Description

The present invention relates to a pesticide spraying device, and particularly to a pesticide spraying device having a portable pesticide spraying device.

Conventionally, there has been a type of agricultural portable pesticide spraying apparatus in which an operator carries a pesticide tank, attaches a nozzle pipe to a hose extending from the pesticide tank, and sprays the pesticide through the nozzle pipe.

In general, these portable pesticide spraying devices are generally not equipped with a measuring device for the pesticide flow rate. For this reason, for example, when pesticide is sprayed on a field or the like, the total amount of the pesticide sprayed on the entire field is obtained by subtracting the remaining amount from the supply amount to the tank. Specifically, for example, it can be calculated from the number of times that the agricultural chemical tank is filled and the final residual amount in the tank. However, with such a calculation method, only a rough amount can be calculated. For example, a large error occurs due to an error in the number of times the tank is full or a misplacement mark. However, since these portable pesticide spraying devices are used for small fields, etc., there has been no particular problem with respect to management of these errors and the total amount of sprayed pesticides.

However, various legal revisions have been made in recent years in order to cope with various problems related to agricultural chemicals. For example, the pesticide use standards have been revised, the use standards to be followed by pesticide users are specifically set, and penalties for violations are also stipulated. In addition, as an effort regulation, it is stipulated that the date of use of the agricultural chemical, the place of use, the crop, the type of agricultural chemical, and the amount of application are recorded.

Furthermore, a positive list system for pesticide residue standards is about to be implemented. Before the implementation of this system, multiple pesticides were registered for one crop, and the residual pesticide standard value for each pesticide was set. Therefore, even if a certain amount of pesticide not registered for the crop was detected, the distribution of the crop was not regulated at all because no reference value was set for that pesticide. However, after the implementation of this system, for pesticides for which residue standards are not defined, a certain amount (0.01 ppm) is defined as the residue standard, and distribution of crops in which agricultural chemicals exceeding this amount are detected is prohibited. become. For this reason, for example, if agricultural chemicals spread in different fields with different crops are scattered and applied to the crop immediately before shipment, and the agricultural chemical is not registered in the crop, the crop is prohibited from shipping. There is a possibility that it will end up.

Therefore, in order to comply with these laws and regulations, agricultural workers who are pesticide users need to pay more attention than ever to pesticide application. Specifically, it may be possible to learn basic spraying operations, and to constantly take care not to scatter pesticides. For this purpose, it is required to spray with an appropriate amount of agricultural chemicals and to manage the amount of spraying more thoroughly than before.

The present invention has been made in view of the above problems, and the object of the present invention is to provide an agrochemical spraying device equipped with a small-sized flowmeter capable of accurately measuring and displaying the amount of agrochemical spraying. The application of agricultural chemicals by quantity and thorough management of the quantity of spraying can be easily performed, so that the prevention of agricultural chemicals scattering is promoted and the burden on agricultural workers is reduced.

The agricultural chemical spraying device according to the present invention is
An agrochemical storage section, an agrochemical sprayer, an agrochemical delivery pipe connecting the agrochemical storage section and the agrochemical sprayer,
A pesticide spraying device equipped with
The agrochemical sprayer is connected to the agrochemical spray nozzle provided at the tip, the nozzle and the agrochemical delivery pipe, and a substantially rod-shaped outflow pipe and support rod having a pesticide outflow passage for allowing the pesticide to flow out, A flow rate detection sensor provided in the pesticide outflow passage, and a digital indicator that digitally displays the amount of the pesticide sprayed from the measurement value from the flow rate detection sensor,
The flow rate digital indicator has a rectangular main body and a display portion provided on the surface of the main body, and the main body is attached so as to be adjustable in the longitudinal direction of the outflow pipe and support rod,

If it is an agrochemical spraying apparatus which concerns on this invention, since the small flowmeter which can measure and display the agrochemical spraying quantity correctly is provided, the agricultural chemical spraying by an appropriate spraying quantity can be implemented easily. In addition, the amount of agricultural chemicals applied can be easily and accurately managed, thereby preventing the scattering of agricultural chemicals and reducing the burden on farmers.

Hereinafter, one embodiment of the agricultural chemical spraying device 1 according to the present invention will be described with reference to the drawings.

FIG. 1 shows the overall configuration of the agricultural chemical spraying apparatus 1. The pesticide spraying apparatus 1 includes a pesticide storage unit 2, a pesticide sprayer 3, and a pesticide delivery pipe 4 that connects the pesticide storage unit 2 and the pesticide sprayer 3.

Here, the agrochemical storage section 2 corresponds to a conventional so-called pesticide tank, and the mode thereof is a small one that can be hung on the shoulder or carried on the shoulder when the pesticide is sprayed, The large-sized thing used with a power sprayer with an engine may be sufficient.

Moreover, the mechanism for sending the agrochemical in the agrochemical storage part 2 to the agrochemical sprayer 3 may be any of a pressure accumulation type, an electric type, and a power type (engine type). Accordingly, the airtightness and pressure resistance are not particularly limited.

The agrochemical delivery tube 4 is, for example, a flexible tube-like material that requires chemical resistance, durability, and the like, and is formed from vinyl chloride, silicon rubber, synthetic resin, or the like. Is preferred. However, it is not limited to the agrochemical delivery pipe 4 made of these materials.

Next, an example of the agricultural chemical spreader 3 is shown in FIGS. The pesticide sprayer 3 is composed of, for example, a substantially rod-shaped outflow pipe / support rod 7 as a main body, and is used for spraying agricultural chemicals at the longitudinal end of the outflow pipe / support rod 7 (right side in FIGS. 2 and 3). A nozzle 5 is mounted. The pesticide spraying nozzle 5 is not particularly limited as long as normal pesticide spraying is possible.

Here, in the vicinity of the agrochemical spray nozzle 5, a flow rate digital display 9 is attached so that the attachment position can be adjusted in the longitudinal direction of the outflow pipe and support rod 7. The flow rate digital display 9 includes, for example, a rectangular parallelepiped main body 10 and a display unit 11 provided on the main body surface. Here, the main body 10 is fastened to the outflow pipe / support rod 7 by the clasp 12 as understood from FIG. 3, and the attachment position can be adjusted by releasing the clasp 12.

Moreover, since the agrochemical spreader 3 is used outdoors, it is preferable that the flow rate digital display 9 is waterproof. Here, the display unit 11 may be configured by using, for example, a monochrome display liquid crystal that can be operated at a low cost and at a low current. In addition, the displayed content can be a numerical display in units and L / min. In the embodiment, for example, a wide measurement range of 0.5 L / min to 35 L / min can be covered.

As described above, a monochrome display is sufficient from the viewpoint of cost as described above, but the following examples are conceivable in order to improve visibility because it is used outdoors.
1. Visibility under sunlight can be improved by using a color liquid crystal display.
2. By providing a window-type cover on the display portion, visibility under bad weather can be improved.
3. Visibility can be improved by enlarging the display by providing a glass with a lens in front of the display unit.
4). By adding a voice display function together with the digital display unit, it is possible to accurately grasp the spray flow rate.
The power source of the flow rate digital display 9 is preferably a battery built-in type.

Meanwhile, for example, two grips 13 are attached to the outflow pipe / support rod 7 in the vicinity of the substantially central portion in the longitudinal direction and the rear end (left side in FIGS. 2 and 3). By supporting the grip during the agricultural chemical spraying operation, an appropriate agricultural chemical spraying operation can be achieved. Moreover, the display part 11 of the said flow volume digital display 9 will be located at the front, and the visibility of the agrochemical flow instruction | indication will improve.

FIG. 4 is an enlarged view of the AA cross section and a part of FIG. As apparent from FIG. 4, an agrochemical outflow passage 6 is formed in the outflow pipe / support rod 7 to connect the agrochemical delivery pipe 4 and the agrochemical spray nozzle 5 to allow the agricultural chemical to flow out. However, for example, the agrochemical delivery pipe 4 may pass through the inside of the outflow pipe and support rod 7 and directly connect to the agrochemical spray nozzle 5.

Here, a flow rate detection sensor 8 is installed in the agrochemical outflow passage 6. As the flow rate detection sensor 8, for example, an impeller type flow rate sensor that measures the rotational speed of the impeller 14 by the fluid and calculates the flow rate of the fluid from the measured amount is used. In this embodiment, the flow rate detection sensor 8 is installed inside the outflow pipe / support rod 7, but the installation position is not limited to the inside of the outflow pipe / support rod 7.

FIG. 5 shows an example in which the flow rate detection sensor 8 is installed outside the outflow pipe / support rod 7. In this embodiment, the agrochemical delivery pipe 4 connected to the agrochemical storage section 2 is connected to one end side of the flow rate detection sensor 8, and the flow rate detection sensor 8 is fastened to the outflow pipe and support rod 7 with a clasp 12, for example. To do. Then, the other end side of the flow rate detection sensor 8 is connected to one end side of the new agrochemical delivery pipe 4, while the other end side of the agrochemical delivery pipe 4 is drilled at a substantially central portion of the outflow pipe and support rod 7. From the communication hole thus formed, it passes through the inside of the outflow pipe and support rod 7 and is directly connected to the agrochemical spray nozzle 5. According to the present embodiment, it is possible to manufacture at low cost because it is easy to manufacture, and it is possible to exhibit effects such as easy maintenance because the flow rate detection sensor can be attached and detached.
