Japanese Patent Laid-Open No. 11-346508

  Since the compost spreader is intended for handling humus compost, manure, etc., it adheres significantly to the loading platform, transport belt, etc., and it is easy to stick, the transport belt is easily deformed, stable feeding and feeding It is difficult to maintain the rotational conveyance of the like. Further, the corrosiveness of the loading platform that receives the conveyor belt is also remarkable.

  The invention described in claim 1 is a compost spreader provided with a conveyor belt 3 that is slidably guided and rotated on the upper surface of the bottom plate 2 of the loading platform 1 to load, feed or convey the compost, and the bottom plate 2 of the loading platform 1. The upper end 6 is fixed to the side wall plate 4 and the lower end edge 7 is brought close to the upper surface of the conveying belt 3 so as to cover the top corner 5 of the cargo bed between the left and right side wall plates 4. An inclined plate 8 that is inclined is provided, and a discharge hole 9 is formed in the bottom plate 2 of the cargo bed bottom corner 5 to form a compost transfer device.

  When the compost loaded on the loading platform 1 is sprayed on the field, the conveyor belt 3 on the upper surface of the loading platform 1 is rotated rearward while the vehicle body is traveling forward, and the compost supported on the upper surface of the conveying belt 3 is rear end. It can be fed to a scraping device or the like and sprayed. Further, when compost can be loaded on the loading platform 1, the compost supplied and placed on the rear end of the conveying belt 3 is fed to the front of the loading platform 1 while the conveying belt 3 is rotated in the reverse direction. Can be loaded. Since the compost conveyed on the upper surface of the conveyor belt 3 is guided and conveyed by the inclined plate 8 at both left and right ends of the conveyor belt 3, the lower end edge of the inclined plate 8 is placed on the upper surface of the conveyor belt 3. The compost that is transported while being positioned at the approaching or sliding contact portion is transported while being guided by the lower end edge 7 of the inclined plate 8 so as to be scooped up to the inclined upper surface side of the inclined plate 8. And the leakage of the compost to the loading platform bottom corner 5 at the lateral edge of the conveyor belt 3 is prevented. Further, when compost or the like leaks from between the upper surface of the conveyor belt 3 and the lower end edge 7 of the inclined plate 8 to the bottom corner 5 of the loading platform, the compost or the like is transferred from the lateral edge of the conveyor belt 3 to the bottom plate 2. Is extruded onto the lateral end surface of the, and discharged through the discharge hole 9. In this way, the compost on the upper surface of the transport belt 3 is smoothly transported to prevent a part of the compost from leaking from the lower end edge 7 of the inclined plate 8 to the outer cargo bed bottom corner 5. Even if some compost, compost scraps, etc. leak into the bottom corner 5 of the loading platform, the upper surface of the conveyor belt 3 is kept rotating in a flat form, so that it is moved outward from the discharge hole 9 of the bottom plate 2. Let it drain. Further, since the amount of compost and the like at the bottom corner 5 of the cargo bed is small and is blocked by the inclined plate 8 so as not to receive the pressing force of the main transport portion compost on the upper surface of the transport belt 3, The adhesion of the compost to the upper surface of the conveyor belt 3 and the upper surface of the bottom plate 2 is weakened so that cleaning after the end of the work can be performed easily and easily.

According to a second aspect of the present invention, a lateral gap 10 is formed at an appropriate height interval between the bottom plate 2 surface and the lower edge of the side wall plate 4 on the outer side of the cargo bed bottom corner 5. A discharge hole 9 is formed in the bottom plate 2 of the gap 10.
As described above, the compost placed on the upper surface is conveyed by the conveying belt 3 rotating on the upper surface of the bottom plate 2. At this time, the compost guided by the left and right inclined plates 8 is guided so as to be scooped up from the upper surface of the conveyor belt 3 to the lower end edge 7 of the inclined plate 8, and the position is maintained inside the conveyance width region. Leakage to the bottom corner 5 side is prevented. Further, the lateral end edge of the conveyor belt 3 is guided by the top surface of the bottom plate 2 of the loading platform corner 5 and rotates, but the lower end edge of the side wall plate 4 positioned on the lateral end, the bottom plate 2 portion, Since a side gap 10 is formed between them and is formed so as to communicate with the load carrier bottom corner 5, a wide gap is formed between the side edge of the conveyor belt 3 and the conveyance belt 3. It is difficult to give resistance to the rotation of the belt 3. Therefore, the inclined plate 8 is set to the outer side as much as possible, the width of the loading platform corner 5 is narrowed, the conveying width of the conveying belt 3 is increased, and the lateral end of the conveying belt 3 in the loading platform corner 5 is formed. The smooth rotation of the belt on the flat surface is maintained by reducing large distortion such as rising of the edge and bending deformation. Further, the discharge hole 9 may be formed below the side gap 10 that forms part or all of the discharge hole 9 outside the side wall plate 4.

Further, even if the lateral edge of the conveyor belt 3 is set so as to be close to the side plate 10, the side gap 10 and the lower discharge hole 9 are formed on the outer side. A resistance phenomenon that gives resistance to the rotation of the conveyor belt 3 at the bottom corner 5 hardly occurs, and the smooth rotation of the conveyor belt 3 can be maintained.

  According to the third aspect of the present invention, the elastic member 11 is provided at the lower end of the inclined plate 8 and the lower end edge 7 of the elastic member 11 is brought into sliding contact with the upper surface of the conveying belt 3. The elasticity of 11 makes it difficult for a large resistance to act on the rotation of the conveyor belt 3, allows smooth rotation to be maintained, and prevents compost from leaking to the bottom corner 5 of the bed. When the elastic material 11 needs to be replaced due to aging, damage or the like, the replacement operation and configuration of only the elastic material 11 can be made simple and easy, and durability can be maintained so as not to damage the conveyor belt 3. it can.
