Description

[Detailed description of the invention] Industrial application field This invention relates to a compost spreader that is towed by a walking-type mobile agricultural machine and performs compost spreading work.

BACKGROUND OF THE INVENTION Conventionally, a typical example of a compost spreader that is towed by a walking-type mobile agricultural machine and performs compost spreading work is the one described in Japanese Utility Model Application Publication No. 156418/1983. According to this compost spreader, a feed-out belt for conveying compost toward a feed-out port at the rear of the hopper is provided at the bottom of a hopper for loading compost in a substantially horizontal state in the front-rear direction, and the length of the feed-out belt in the front-rear direction is The width dimension is set larger than the width dimension of the hopper in the front-rear direction. Further, a connecting fitting of the compost spreading machine for connecting the compost spreading machine and the mobile agricultural machine is provided in front of the feeding belt.

Problems that the invention aims to solve: Even if the overall length of a compost spreader connected to a mobile agricultural machine is the shortest, the length of the delivery belt and the length from the compost spreader's coupling fitting to the tip of the mobile agricultural machine It is the sum of the above, and it is getting larger.
For this reason, there are drawbacks such as a large turning radius and poor maneuverability for trajectory correction.

This idea was developed in view of these points, and aims to provide a compost spreader that can shorten the overall length when connected to a mobile agricultural machine and improve operability such as turning and trajectory correction. purpose.

Means for Solving the Problems A vehicle body 4 having a grounding wheel 3 that rotates while being in contact with the ground is detachably connected to a rear hitch 21 of a walking type mobile agricultural machine 19. A car body 4 is provided with a hopper 5 for loading compost, and a delivery belt 8 is provided at the bottom of the hopper 5, which rotates with the rotation of the grounding wheel 3 and conveys the compost toward a delivery port 9 at the rear of the hopper 5. Vehicle body 4 connected to rear hitch 21
At least a part of the connecting fitting 18 is positioned closer to the hopper 5 than the front end of the feeding belt 8.

Operation When the vehicle body 4 is connected to the mobile agricultural machine 19, the feed belt 8 and the rear hitch 21 of the mobile agricultural machine 19 are overlapped, and the total length of the state in which the vehicle body 4 and the mobile agricultural machine 19 are connected is shortened accordingly.

Embodiment An embodiment of this invention will be described based on the drawings. A vehicle body 4 is provided, which rotatably holds an axle 2 approximately in the center of a chassis 1 extending in the front-rear direction, and has ground wheels 3 attached to both ends of the axle 2. The car body 4 is provided with a hopper 5 for loading compost.
At the bottom of the hopper 5, there are a pair of front and rear feeding rollers 6,
A feeding belt 8 is provided which is wound between the belts 7 and 7. In addition, the outlet 9 formed at the rear of the hopper 5
A comb-like scraping rotary body 10 is rotatably held facing the feed belt 8 and located above the feed belt 8. The hopper 5 is covered with a cover 11 attached to the side thereof, and the rotation of the grounding ring 3 is controlled by the rotating shaft 12 of the feeding roller 7 and the scraping rotary body 1.
A power transmission mechanism (not shown) consisting of a chain, sprocket, etc., which transmits power to the rotating shaft 13 of the engine 0, is provided. A soil plate 14 that forms a fertilizer groove is connected to the front of the chassis 1, and a fertilizer collecting plate 15 that guides the compost falling from the outlet 9 to the fertilizer groove is connected to the rear of the chassis 1. Covering ring 16
are connected. Further, a shutter 17 for adjusting the opening width of the outlet 9 is attached to the hopper 5 so as to be slidable in the vertical direction.

Next, a connecting fitting 18 is fixed to the front part of the chassis 1 in close proximity to the hopper 5, and is connected to the connecting fitting 18 by a connecting pin 20 at the rear of the walking-type mobile agricultural machine 19 in the direction of movement. A rear hitch 21 is fixed. The connecting fitting 18 is located behind the front end of the feeding belt 8, and is connected to the connecting fitting 18.
The rear hitch 21 and the feed belt 8 overlap.

In such a configuration, the vehicle body 4 is connected to the moving agricultural machine 1.
9 and towed by the mobile agricultural machine 19, the vehicle body 4
run. As the vehicle body 4 moves, the grounding wheels 3
and the axle 2 rotate integrally, and this rotation is transmitted to the rotating shafts 12 and 13 via the power transmission mechanism within the cover 11.
can be conveyed to. Then, the rotating shaft 12 and the feeding roller 7 rotate integrally, so that the feeding belt 8
rotates in the direction of arrow a and transports the compost in the hopper 5 toward the outlet 9. Furthermore, the rotating shaft 13 and the scraping rotary body 10 rotate integrally, and the compost conveyed by the feeding belt 8 is dropped from the feeding port 9. The compost falling from the outlet 9 is guided by a fertilizer collecting plate 15 into the fertilizing groove formed by the soil plate 14, and is covered with soil by a soil covering ring 16.

Next, the vehicle body 4 and the mobile agricultural machine 19 are connected by connecting the connecting fitting 18 and the rear hitch 21 with a connecting pin 20, and the rear end of the rear hitch 21 is connected to the front end of the feeding belt 8. It is located at the rear. For this reason, the vehicle body 4 and the mobile agricultural machine 1
9 is connected, the total length becomes shorter, the turning radius becomes smaller, and the width of the headland becomes narrower. In addition, the operability such as trajectory correction is improved. Furthermore, the center of gravity of the fertilizer spreader with the hopper 5 and the like attached to the vehicle body 4 becomes closer to the mobile agricultural machine 19, and the turning operation is performed by pushing down the bar-like handle 22 of the mobile agricultural machine 19 using the running wheels 23 of the mobile agricultural machine 19 as a fulcrum. It's easy to do.

Effects of the invention As mentioned above, this invention locates at least a part of the coupling fittings of the car body closer to the hopper than the front end of the feed belt, so that when the car body with the hopper etc. attached is connected to a mobile agricultural machine, The overall length can be shortened, which improves maneuverability such as turning and course correction.Furthermore, the turning radius can be reduced, the width of the headland can be narrowed, and the center of gravity on the vehicle side can be reduced. This has the advantage that turning operations, which are performed by lifting or pushing down the rod-shaped handle of the mobile agricultural machine by bringing the handle close to the mobile agricultural machine, can be easily performed.
