Description

[Detailed Description of the Invention] [Industrial field of application] In the present invention, a threshing device is equipped with a discharge straw cutter for shredding discharged straws and a chemical spraying device acting on the shredded discharge straws at the rear portion thereof. The present invention relates to a combine drug spraying structure.

[Conventional technology]

The above-mentioned chemical spraying device for combine harvesters adds chemicals such as a ripening agent to shredded waste straws in order to corrode straw debris that has fallen on the ground to generate humus soil, and is conventionally shown in FIG. As described above, the medicine is sprinkled on the shredded discharge straw after it has exited the discharge passage (15) below the discharge straw cutter.

[Problems to be solved by the device]

According to the above-mentioned conventional technique, since the medicine is spread only on the surface of the straw dust accumulated on the ground, it is difficult to mix the straw dust below the surface with the medicine, and the medicine is exposed to sunlight. As a result, the microorganisms contained in the drug are prone to death, and the desired corrosive action is not exhibited.

The present invention has an object to solve the above-mentioned inconvenience by allowing a drug and straw waste to mix well.

[Means for Solving the Problems]

In order to achieve the above object, the present invention is a combine drug spraying structure in which a threshing device rear part is equipped with a waste straw cutter for shredding waste straws and a chemical spraying device acting on the shredder straws. A skirt portion that forms a discharge passage for shredded discharge straw is provided below the discharge straw cutter, and a drug dropping hose is provided on the side wall of the skirt so that the discharge end of the drug dropping hose of the chemical spraying device faces the discharge passage. And a portion of the side wall through which the medicine dropping hose penetrates is configured as a guide plate pivotally supported by the side wall so as to be swingable around a horizontal axis.

[Action]

According to the above-mentioned characteristic configuration, the straw dust shredded by the exhaust straw cutter will be sprayed toward the straw dust while it is falling on the ground, so when it falls on the ground surface, Straws are mixed well. That is, the chemicals are evenly attached to the straw debris deposited on the ground regardless of the upper and lower parts of the deposited layer.

In addition, since the guide plate that penetrates and supports the medicine dropping hose can be swung around the horizontal axis, the angle of the discharge end at the lower end of the hose can be changed, and the mixing degree of the medicine and the shredded discharge straw can be adjusted. It is also possible to adjust the reflection angle when the falling shredded discharge straw collides with the guide plate, and it is possible to further promote the mixing of the medicine and the straw waste.

[Effect of device]

As a result, a relatively simple modification based on changing the placement position of the chemical dropping hose can improve the chemical spraying efficiency and further promote the corrosive action of straw debris, providing a more fertile soil. It has been possible to economically provide a drug spraying structure that enables the above.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 8, a threshing device (3) is mounted on a vehicle body (2) having a pair of left and right crawler traveling devices (1), and a cutting pretreatment section (4) is provided at the front end of the vehicle body (2). The combine is configured.

In the combine, a transfer route is formed so that the cut culm from the pre-cutting processing section (4) is supplied to the feed chain (5) of the threshing device (3), and the cut corn supplied to the feed chain (5) is supplied. After the grain culm is treated by the threshing device (3), it is sent to the upper rear part of the vehicle body (2) as a discharging straw, and the discharging straw cutter (A) provided at the rear end of the threshing device (3). To be sent to.

As shown in FIGS. 1 and 7, this discharge straw cutter (A) has disc-shaped cutting blades (7) at predetermined intervals in the axial direction with respect to a cutting blade shaft (6) having a hexagonal cross section. A rotary blade (B) having a large number of blades and a rotary blade having a large number of disk-shaped blades (9) arranged at predetermined intervals in the axial direction with respect to the blade (8) having a hexagonal cross section. The blade (C) is provided in parallel with each other, and the threshing device (3) has a handling barrel (10) for handling a grain culm bundle conveyed by a feed chain (5) and a handling barrel (1).
Oscillation sorting mechanism (1) that sorts the processed products from
1) and Kara Minoh (12) that sends sorting wind to the swing sorting mechanism (11)
And a dust-exhausting fan (13), and the threshing device (3) is a dust generated when sorting a processed material from a handling chamber (not shown) in which a handling barrel (10) is housed. Is configured to be discharged together with the selected wind from an exhaust port (3a) formed on the rear surface side of the vehicle body.

Further, the discharge straw cutter (A) is installed at a position above the discharge port (3a) as shown in FIG. 1, and is directed downward so as to drop and discharge the shredded discharge straw. A discharge passage (15) is formed, and two rotating bodies (1) are provided at a lower portion of the discharge passage (15) at a level below the discharge port (3a).
A diffusion emission device (D) having 4) and (14) is provided.

That is, each of the rotating bodies (14), (14) of the diffusion emission device (D) is provided with a plurality of blade bodies (14a) and the rotation axis (14b) thereof is set to be substantially vertical. By setting the rotation direction as shown by the arrow in the figure, shredded straw from the discharge straw cutter (A) and straw debris from the discharge port (3a) are diffused to the already cut side of the field. It can be released.

As shown in FIG. 1, a drug spraying device (E) is attached to the rear of the discharge straw cutter (A), and a drug dropping hose (1) for spraying the drug in the drug storage hopper (16) is provided.
This hose (17) is provided with multiple 7) installed side by side.
The discharge end portion (17a) of this is provided in the discharge passageway (15).

That is, on the rear wall [corresponding to the side wall] (18) of the skirt (S) for forming the discharge passage (15), as shown in FIG. ₁ ) A guide plate (19) which can be swung around is pivotally supported so as to also serve as a part of the rear wall (18), and a mounting port (20) for inserting a hose is attached to the guide plate (19). It is provided in parallel at four locations.

As shown in FIG. 4, the mounting opening (20) is provided with a guide plate (19).
It is provided on the rear surface side and is configured to be swingable around the lower horizontal axis (P ₂ ), and is closed by a lid (21) which is biased to swing forward.

Therefore, as shown in FIG. 2, by inserting the discharge end (17a) of the hose (17) into the mounting opening (20) by opening the lid (21), the drug is guided through the discharge passageway (15). It comes to adhere to the shredded straw scraps that are scattered.

Further, as shown in FIG. 3, when the guide plate (19) is swung inward, straw chips are reflected by the guide plate (19) and are directed toward the diffusion emission device (D). Discharge passage (1
It is possible to further enhance the diffusion of straw dust that scatters and falls 5), and to promote the mixing of the drug and straw dust.
