Description

[Detailed Description of the Invention] [Industrial Field of Application] The field of application of the present invention is a grass collection device for a riding mower such as a lawn tractor, a ride mower, or a mower attached to an agricultural tractor.

[Prior art]

As shown in Japanese Utility Model Application Publication No. 60-141732, the discharge port of the grass clippings discharge tube for discharging the grass clipped from the grass cutting section to the grass collecting section is arranged so as to face the mounting hole provided on one side wall of the grass collecting section. It was configured to be attached to.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the grass clippings discharge tube was installed so that its discharge port faced the mounting hole provided on one side wall of the grass collecting section, so that the grass clippings were discharged from an uneven position within the grass collecting section. There was a problem when the grass clippings were not collected evenly in the grass collection section.

[Means to solve the problem]

This invention takes technical measures to solve the above problems. That is, in a riding mower that is configured to have a mowing section movable up and down on the vehicle body and to send cut grass to a grass collection section provided on the vehicle body through a discharge tube, the discharge tube is collected from the side of the grass collection section. Along with protruding to the inside of the grass part to the extent of its inner width.

One side of the protruding discharge tube near the axis was cut off to form a discharge port.

[Effect]

When mowing work in a grassy area, the vehicle body is rotated to the left, and the mowing unit is driven to remove the grass clippings from the side of the mower deck, through the grass discharge tube, and generate the grass clippings by the rotational movement of the cutting blades. The grass is transported by the centrifugal force and wind pressure, and is discharged from the outlet into the grass collecting section and stored.

〔effect〕

This invention provides a riding mower that is configured to have a mowing section movable up and down on the vehicle body and to send the cut grass through a discharge tube to a grass collection section provided on the vehicle body. The grass clippings are made to protrude to the inside of the grass collection part to the extent of its inner width, and one side of the protruding discharge tube is cut off from near the axis line to form a discharge port, so that the grass clippings discharged from the discharge port is The capacity of the grass collecting part can be effectively utilized, and the number of times one worker releases grass clippings from the grass collecting part to the outside can be reduced, thereby increasing work efficiency.

〔Example〕 Hereinafter, the present invention will be described in detail based on the drawings.

First, the configuration will be explained. Lawn tractor body 1
The engine 2 is mounted on the front of the engine 2, and an output shaft (not shown) protrudes downward, and an engine pulley (not shown) is attached to the engine 2. At the bottom of the vehicle body 1 between the front wheels 3, 3 and the rear axles 4, 4, there are lifting links 5, 5, 6, 6 whose upper portions are pivotally connected to the vehicle body 1.
The lower part of the mower deck 8 of the mowing device 7 is pivotally connected to the left and right support brackets 9, 9 arranged in parallel so as to wrap around the upper part and the front and rear parts of the mower deck 8, and the mowing device is attached to the lift arm 10 of the vehicle body 1 via the lift rod 11. The engine V 7 is connected so as to be movable up and down, and a front support support 12.12 is attached to the front of the support brackets 9, and a rear support support 13.13 is attached to the rear of the support brackets 9, 9.
The upper belt transmission mechanism is constructed by passing the V-belt 17 over the input V-pulley 16 attached to the input shaft 15 protruding upward from the work transmission case 14 provided on the ceiling wall (not shown) of the moadetsuki 8 and the boob. In the ceiling space (not shown) formed by the lower ceiling wall of the work transmission case 14 and the lower partition wall (not shown), there are three working vertical shafts (not shown) provided with blades (not shown) at the lower ends. This vertical work shaft is rotatably attached to the lower bulkhead so that the vertical work shaft (not shown) protrudes, and the work is transmitted via a V pulley (not shown) and a V belt (not shown) installed on the top of the vertical work shaft. The V-belt is passed through the output V-pulley (not shown) provided on the output shaft (not shown) that protrudes from the case 14 into the ceiling space and the V-pulley (not shown) provided on the upper part of the vertical work shaft to transmit the lower belt. It constitutes a mechanism. This lower belt transmission mechanism is provided with a working clutch (V4 not shown) that connects and disconnects power by loosening and tensioning the V-belt. Car body 1
A collector box 19 is removably attached to the rear hitch 18 of the collector box 19, and a bottom portion 21 of the collector box 19 can be opened and closed by an operating lever 20 provided at the front portion. Discharge port 22 provided on the right side of the moadetsuki 8
A lower discharge pipe 23 whose lower part is attached to the rear shaft 4 is provided so as to protrude from the front side of the right rear axle 4 around the outside so as to face obliquely rearward and upward, and from the right side wall 24 of the collector box 19 to the front wall 25 of the collector box 19. A discharge port in which the rear part of the upper discharge n26 which is attached so as to protrude along the width direction is cut out to make the front part a discharge guide part 27, and a curved surface part 28 is formed such that the tip thereof faces toward the left and right center. A portion 29 is provided, and the outside of the upper discharge pipe 26 is provided along the right side wall 24 of the collector box 19 and protrudes so as to face downward on the front side, and the lower discharge pipe 23 and the upper discharge pipe 26 are provided on the outside of the rear shaft 4 on the right side. They are connected by a located intermediate discharge pipe 30.

Next, the functions and effects of this embodiment will be explained.

After starting the engine of the agricultural tractor and lowering the mowing device 9 by operating the hydraulic lifting device, connect the work clutch and the running latch, and move the vehicle body 1 to the left along the turf grass in the garden. When mowing work is carried out while traveling in a circular motion, the grass clipped by the rotation of the blade is transferred from the discharge port 22 of the mower deck 8 to the lower discharge tube 23 by the centrifugal force and wind force generated by the rotation of the blade. The waste is conveyed to the collector box 19 via the intermediate discharge tube 30 and the upper discharge tube 26, and is also guided by the discharge guide section 27, discharged from the wide discharge port 29 toward the bottom of the collector box 19, and stored. When the collector box 19 is full, the grass clippings are discharged to the outside by operating the operating lever 20 and opening the bottom 21.

In the embodiment described above, the 11-port discharge tube 26 extends from the right side wall 24 of the collector box 19 to the collector box 19.
is attached so as to protrude in the width direction along the f-wall 25, and inside the collector box 19, the rear part of the upper discharge pipe 26 is cut out and the front part is used as a discharge guide part 27, and the Since the discharge port 29 is formed on the curved surface 28 with the tip facing toward the left and right center, the grass clippings discharged from the lower mower deck 8 are dispersed in the collector box 19 and are kept at a uniform height. Thus, the volume of the collector box 19 can be used effectively, and work efficiency can be improved.
