Description

[Detailed description of the device] (b) Industrial field of application The present invention is a granular powder spreader for spraying granular powder such as coal and poultry manure. Cleaning of the bottom plate, shutter plate and agitator provided at the bottom of the hopper. Is easy to do.

(B) Conventional technology Conventionally, in a granule dusting machine, a bearing plate that supports an agitator shaft at the bottom of a hopper is used in order to easily clean the inside when the object to be sprayed changes from coal to chicken manure or the like. It is publicly known that the agitator shaft and the agitator portion can be removed laterally by removing them.

The present invention makes it easier to clean the agitator and the bottom plate.

(C) Problems to be solved by the invention In the conventional technique, even if the agitator shaft and the agitator part can be taken out to the side together with the bearing plate part, the spraying remaining inside the opened hopper The work of taking out the medicine was troublesome.

In the present invention, the mechanism of the bottom plate and the shutter plate forming the bottom of the hopper 7 can be integrally opened and rotated,
The scattered material left inside can be easily removed for complete cleaning.

(D) Means for Solving the Problems The purpose of the present invention is as described above, and the configuration for achieving the purpose will be described below.

In a configuration in which the granular powder in the hopper 7 is agitated by the agitator 3 and sprayed by dropping from the drop hole 1b, a pivotal fulcrum is provided at approximately the center of the hopper 7 in the left-right direction, and the bottom plate 1 and the shutter plate 2 separated into the left and right sides are provided. The mechanism is such that both end positions can be tilted downward and opened.

Further, the agitator 3 is fixed to the agitator shaft 9, and the bearing plate 4 for bearing-supporting both ends of the agitator shaft 9 can be attached to and detached from the hopper side plate 7a of the hopper 7. The agitator shaft 9 has a central bevel gear box. The 8 parts can be separated and attached to the left and right.

(E) Embodiment The purpose and construction of the present invention are as described above. Next, the construction of the embodiment shown in the accompanying drawings will be described.

FIG. 1 is a front view of the granule dusting machine of the present invention, FIG. 2 is a perspective view of the same in an exploded state, and FIG. 3 is a side sectional view.

The granule dusting machine of the present invention is called a lime sower, and it is attached to the working machine mounting device of the tractor, so that the granules can be sprayed in a wide range in a direction perpendicular to the traveling direction. It is made wide.

The hopper 7 is formed over the entire width, and the bottom plate 1, the shutter plate 2, and the agitator 3 are arranged below the hopper 7.

Power is transmitted from the PTO shaft of the tractor to the input shaft 13 via the universal joint, and the input shaft 13 is changed to the rotation of the power transmission shaft in the left-right direction by the bevel gear device inside the bevel gear box 8. Of.

Further, in the present invention, the bevel gear box 8 is arranged at the central position on the left and right of the substantially granular powder spraying machine, and the pivotal support portion of the bottom plate mechanism is provided on the left and right of the bevel gear box 8.

As clearly shown in FIG. 2, the bottom plate mechanism is composed of a “U” -shaped bottom plate 1 and a shutter plate 2 attached to the lower surface of the bottom plate 1 so as to be slidable left and right by a guide piece 15. Is there.

The bottom plate 1 is provided with a drop hole 1b, and the shutter plate 2 is also provided with a shutter opening, so that the granular powder is dropped at a position where the both coincide with each other.

The bottom plate mechanism is provided on the left and right sides, has substantially the same length, and the pivotal protrusions 1a and 1a are projected from the center.

The pivot shaft 5 is inserted into the pivot projections 1a, 1a, and the pivot shaft 5
Is screwed onto the pivoting female screw shaft 17.

With this structure, the bottom plate mechanism is pivotally supported at the central end of the pivotal projections 1a and 1a, and the pivotal support shaft 5 inserted into the pivotal projections 1a and 1a as shown in the left half of FIG. Is configured so that it can be opened and rotated downward.

Since the bottom plate mechanism needs to be closed at the time of working, the locking metal fitting 6 is hooked on the locking piece 10 and is inserted into the guide recess 16 of the hopper 7 as shown in FIG.
Until the fitting projection 1c at the upper end of the bottom plate 1 is fitted, it is attracted and fixed by the locking metal fitting 6.

Also, by opening the bottom plate mechanism, the hopper 7
The granular powder remaining in the lower part of the agitator can be taken out, but the agitator shaft 9 that supports the agitator 3 can be detached in order to completely clean the inside.

A central portion of the agitator shaft 9 is locked by a pin 14 to a base shaft 11 protruding left and right from the bevel gear box 8, and the pin 14 is removed and fixed to the lower part of the hopper side plate 7a by a fastening bolt 12. By removing the plate 4, the agitator shaft 9 and the bearing plate 4 can be integrally removed without removing the fitting portion of the bearing plate 4 of the agitator shaft 9 with the bearing.

(F) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

First, in the granule dusting machine, it is necessary to completely clean the inside of the hopper 7 when the dusting agent is changed from coal to chicken manure, but the mechanism of the bottom plate 1 and the shutter plate 2 By inclining and opening so that both ends face downward, the granular powder remaining in the portion of the bottom plate 1 can be easily taken out, and the granular powder adhered to the portion can also be scraped off. is there.

Secondly, by removing the mechanism of the bottom plate 1 and the shutter plate 2, the pin 1 of the connecting portion with the base shaft 11 of the agitator shaft 9 is removed.
The work of removing the bearing plate 4 is simplified, and the work of removing the bearing plate 4 is also easy.

Thirdly, as described above, the cleaning is easy, and after the cleaning, the bottom plate 1, the shutter plate 2 and the agitator 3 are again used.
The work of assembling the agitator shaft 9 can be simplified.
