Description

[Detailed Description of the Invention] The present invention relates to an improvement of a manu- spreader. In recent years, many proposals have been made to widen the spreading width of manure spreaders, especially those in which the spreading part mechanism is forcibly guided to the spreading blade by a guide cover placed close to the cutting and crushing of compost by a crusher beater. However, there was a drawback that compost adhered to and accumulated on the inner surface of the guide cover. The present invention has been devised in view of this point, and provides a structure in which an elastic thin material is attached to the inner surface of the guide cover to prevent adhesion and accumulation of cut or crushed compost.

The configuration will be described below based on the drawings in which the present invention is implemented. 1 is a cargo frame with a front wall 2, side walls 3 and a floor plate 4
A transfer chain 5 is hung on the floor plate 4. Reference numeral 6 denotes a traction rod, which is vertically installed at the lower central portion of the load frame 1 , and forms part of the support frame of the load frame 1 , and the tip of the traction rod 6 is connected to a hitch at the rear of the tractor. 12 indicates the input shaft, the tractor
The crushing beater 11 , the dispersing blades 10, and the transfer chain 5 are driven by receiving rotational force from the PTO shaft through an appropriate internal speed change means.

FIG. 2 is a cross-sectional view showing the details of the dispersion section, and eleven crushing beaters are horizontally installed in parallel to the rear upper surface of the floor plate 4, and have a large number of cutting blades fixed thereto. Reference numeral 10 denotes a dispersing blade which is arranged in parallel facing the final end of the floor plate 4 and fixed to a rotating shaft protruding from the horizontal case 14. In this embodiment, the dispersing blade 10 is attached to the upper surface of a pair of disks.
They are grown by planting 3 of each.

Reference numeral 19 denotes a mounting frame which covers the upper part of the crushing beater 11 , and a guide cover 9 is connected to the rear edge of the mounting frame. The guide cover 9 has a substantially arcuate cross-section, has a side plate 13 on the inside thereof, and is disposed close to the rotational tip locus of the crushing beater 11 , with its lower end approximately at the center of the dispersing blade 10. (Side view)

Reference numeral 15 is made of an elastic thin material, and a stopper 17 is installed horizontally along the inner wall surface of the guide cover 9 and fixed with a set screw.
In this embodiment, a synthetic rubber material is used as the elastic thin material 15, but the gist does not change even if it is made of a flexible synthetic resin thin material.

Reference numeral 16 denotes a rubber plate divided into appropriate widths and suspended from the lower end of the guide cover 9, and the rubber plate 16 is placed close to the upper surface of the dispersing blade 10.

With the above structure, when the transfer chain 5, the crushing beater 11 , and the spreading blades 10 are driven, the compost gradually moves backward, is cut and crushed by the cutting blade of the crushing beater 11 , and is raked upward. The particles are struck by the inner surface of the guide cover 9 and broken into pieces, which are further forcibly guided to the center surface of the scattering blades 10 and dispersed over a wide area. At this time, since an elastic thin material 9 is attached to the inner surface of the guide cover 9 close to the crushing beater 11 , adhesion of the fragmented compost is prevented, and unlike the conventional method, the spreading efficiency is reduced due to adhesion and accumulation of compost. Spraying work has become more comfortable as there is no need to waste energy or power.
