Description

[Detailed Description of the Invention] The present invention relates to a manure spreader. The present applicant has already published patent publications No. 58-216608 and Japanese Patent Application Publication No. 59-66802 as inventions relating to manure spreaders.
JP-A-59-140805 was proposed. The present invention particularly relates to an improvement of a guide body that regulates the falling position of compost.

In Maniure Spretzda, when compost is applied as top dressing to pastures, there is a drawback that if the lumps adhere to the grass plants, they lose their regenerative power.

In this invention, the upper part of the rear part of the conveyor which transfers the compost is
A crushing beater is provided that rotates in the same direction as the conveying body, and a dispersing body that faces the lower rear of the conveying body and rotates at high speed is disposed horizontally in the axial direction of the crushing beater, and is placed above the dispersing body. A guide body is swingably installed vertically to cause the crushed compost to fall into a compost fall zone formed on the side of the conveyor at the center of the spreading body, and the lower part of the guide is in contact with the terminal end of the conveyor. By providing a manure spreader that can be extended and configured so that the amount of compost supplied can be adjusted, the manure spreader surrounds the rear edge of the crushing beater, tightens the amount of compost supplied, and crushes the compost. The purpose is to ensure the effect of fine particles and supply them to the dispersion body, making it possible to disperse very small amounts of fine particles, and also to double as a closing shutter when used as a transport vehicle for silage or semi-sludge. .

Next, an explanation will be given based on the drawings. Fig. 1 is a side view of the embodiment, and 1 is a cargo frame with front wall, side wall and floor plate 2.
The floor plate 2 has a floor conveyor 3 which is a conveyor.
It will be hung. Reference numeral 4 denotes a traction rod, which is not shown, but also serves as a part of the frame 5 forming the bottom of the tractor.

6 and 7 are crushing beaters that rotate in the same direction as the floor conveyor 3, and the crushing beaters 6 and 7 are installed horizontally above the floor conveyor 3, and the rotation locus of the conveyor end of the floor conveyor 3 and the crushing beater 7 is Arrange so that the rear ends are in approximately the same position. The crushing beater 6 is provided above the front part of the crushing beater 7. A support frame 8 is provided above the crushing beaters 6, 7, and a guide plate 9 serving as a guide body is provided at the rear of the support frame 8 so as to cover the crushing beaters 6, 7. Reference numeral 10 denotes a dispersion section, which in this embodiment is made up of four dispersion members 11, which are dispersion bodies, arranged horizontally, and each of the left and right sides rotates outward relative to the center.

FIG. 2 is a schematic plan view showing power transmission, and 12 is an input shaft that connects the left and right counter shafts 1 through a distribution box 13.
4, 14'. The counter shaft 14 rotates a second shaft 16 that drives the crushing beater 7 and a drive shaft 17 that drives the dispersion member 11 . Its second axis 16
rotates the first shaft 15 which drives the crushing beater 6. On the other hand, the counter shaft 14' drives a conveyor drive shaft 18 which drives the floor conveyor 3 via a transmission box 19. Although the input shaft 12 is not shown, it transmits power from the tractor PTO shaft.

The dispersing member 11 is fixed to a vertical shaft protruding upward from the transmission box 20, and the dispersing member 11 is made up of a flat plate 21 formed in an elongated shape with blades 22 standing upright.
Adjacent dispersion members 11 are sequentially installed horizontally with a phase difference of 90 degrees, and the rotational trajectories of the tips of adjacent blades 22 overlap. Reference numeral 23 denotes a bottom plate whose rear end slightly protrudes from the rotation locus of the tip of the blade 22, and at the front end there is a guide standing plate that surrounds the front and side portions that are close to each other along the rotation locus of the tip of the blade 22. 31 to prevent the compost from scattering forward.

Figures 3 and 4 show the main parts of this embodiment.
The guide plate 9 is rotatably provided on the support frame 8 so as to cover the crushing beaters 6 and 7, and is equipped with an elastic material 30 at the lower end. A connecting rod 24 is pivotally attached to the upper surface of the support frame 8, and connecting plates 25, 25,
26 is fixed. The ends of the connecting plates 25, 25 are connected to brackets 27, 27 provided on the guide plate 9 via auxiliary plates 28, 28. 29
The base is pivoted to the side of the support frame 8 by a cylinder, and the tip is pivoted between the connecting plates 25 and 26. The elastic material 30 at the lower end of the guide plate 9 is arranged so as to come into contact with the transfer end of the floor conveyor 3 when the guide plate 9 is rotated downward by the expansion and contraction of the cylinder 29.

Next, to explain the operation, when moving and conveying, the cylinder 29 is contracted and the guide plate 9 is rotated downward, and the elastic material 3 at the lower end of the guide plate 9 is attached to the transfer end of the floor conveyor 3.
This is to prevent the compost from flowing out by bringing the 0 into contact with it. During spraying, the power of the tractor is transmitted to the input shaft 12, the cylinder 29 is extended, and the opening degree of the guide plate 9 is adjusted.
In particular, when the purpose is to spread fertilizer on pastures, the opening degree of the guide plate 9 is made small, and the trailing end of the crushing beater 7 is surrounded and tightened to ensure the crushing action of the compost and make it fine. It is something to do. At this time, the finely granulated compost falls to the front side of the spreading member 11 and is given a sufficient releasing force to be spread over a wide area.

In the general work, the dropping position to the spreading member 11 is controlled according to the properties of the compost, and the desired spreading accuracy and spreading width are adjusted to perform the work efficiently.

In addition, the transfer speed of the floor conveyor 3 and the expansion and contraction of the cylinder 29 are controlled remotely from the tractor operator's seat to control the amount of compost supplied to the spreading member 11 and the position at which it falls depending on the situation.

The structure described above ensures the crushing action of the compost and enables fine-grained spraying, making it versatile for not only general spraying work but also for top-dressing compost on perennial crop fields in pastures, etc. has improved. Moreover, it can also be used as a closing gate when transporting silage or semi-sludge, making it extremely economical as one manure spreader can be used for multiple purposes.
