Description

[Detailed description of the invention] [Field of industrial application] The present invention is mainly concerned with the crushing device of a broadcaster that spreads powder and granules. It is related to the device.

[Conventional technology]

Conventionally, well-known broadcasters have been used to feed powdered fertilizer, grass,
It was used to spread wheat seeds, etc. over the entire surface of the hopper, using a scattering disk that applied a centrifugal force to the powder at the bottom of the hopper.

For example, as disclosed in Japanese Utility Model Application Publication No. 54-80915, a stirring mechanism for stirring the powder in the hopper is attached to a stirring shaft that rotates at the same time as the above-mentioned scattering plate. The powder and granules were crushed.

[Problem that the invention attempts to solve]

However, using this traditional broadcaster,
For example, when trying to spray a compound fertilizer containing urea, etc.
Because the solidified fertilizer cannot be sufficiently crushed during the process of feeding it from the fertilizer bag to the hopper, clogging often occurs at the discharge port at the bottom of the hopper, and the stirring mechanism in the hopper alone is not sufficient to crush the solidified fertilizer. There wasn't.

In addition, when feeding this solidified fertilizer from the fertilizer bag to the hopper, it takes a lot of time to completely crush the solidified fertilizer by stepping on it with your feet while raising and lowering the heavy fertilizer bag. Was.

[Means for solving problems]

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a crushing device for a broadcaster that can completely crush powder solidified at the stage of supplying powder to a hopper in a broadcaster.

For this purpose, the broadcaster crushing device of the present invention is equipped with a rotary disk having a crushing blade on the top of the stirring shaft of the hopper supply part of the broadcaster, and a scattering prevention cover with a receiving blade attached to the rotary disk. In addition to crushing the solidified powder by rotation, the crushing effect is further enhanced with the anti-scattering cover.
This device is characterized by supplying free-flowing powder and granules that do not clump into the hopper, allowing for clogging-free dispersion work.

EXAMPLE Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 indicates a broadcaster equipped with a hopper 2, a scattering plate 3, a stirring shaft 4, etc., and this broadcaster 4 is attached to the rear of a tractor (not shown) via a frame 5. ing.

The stirring shaft 4 is located at the center of the scattering plate 3 and extends within the hopper 2 to the vicinity of the supply port of the hopper, and a spiral stirring metal fitting 6 is attached to the outer periphery of the base side thereof.

The stirring shaft 4 is driven by receiving power from a PTO shaft of a tractor (not shown).

Further, a disk-shaped rotary disk 7 is provided at the top of the stirring shaft 4, and is fixed to the stirring shaft 4 with bolts 8.

As shown in FIG. 2, on this rotary disk 7, a plurality of crushing metal fittings 9 are vertically installed at equal angular intervals in the radial direction, and the crushing metal fittings 9 have a crushing blade 10 and a crushing comb blade 11. It is attached to the rotary disk 7 with mounting bolts 12.

The crushing blades 10 and the crushing comb blades 11 intersect at right angles, and large particles such as solidified fertilizer are removed by the crushing blades 10.
When the small lumps are received in the pocket and released by centrifugal force, they are sequentially impacted by the grinding comb blades 11 and are crushed and released outward.

Further, a scattering prevention cover 13 is provided above the rotary disk 7, and this scattering prevention cover 13 is attached to the upper outer periphery of the hopper 2 with a clip 14, and a supply port 15 is provided in the center.
is open.

A plurality of annularly connected receiving blades 16 shown in FIG. 3 are attached to the back surface of the scattering prevention cover 13 so as to be located on the outer circumferential side of the crushing metal fitting 9 of the rotary disk 7, as shown in FIG. The powder and granules discharged outward from the rotary disk 7 while being impacted by the crushing fitting 9 are further transferred to the receiving blade 1.
6, and those that are still solidified are carried around until they are crushed.

In such a configuration, for example, to perform fertilization work, first attach the broadcaster 1 to the tractor, and then drive the rotary axis of the tractor.The agitation shaft 4 and rotary disk 7 will start rotating, and the fertilizer will be applied. When the fertilizer is supplied from the supply port 15 opened above the scattering prevention cover 13, the fertilizer supplied to the rotary disk 7 is given an outward ejection force by centrifugal force, but at this time, the crushing fitting 9 and the receiving blade 16 absorb the impact. The solidified fertilizer is crushed while being received, and the free-flowing powdered fertilizer is supplied into the hopper 2 from between the receiving blades 16.

In addition, in the above example, powdered and granular fertilizer was explained, but
It is also effective even for seeds that tend to clump, and is expected to have a labor-reducing effect, especially during the humid rainy season, in humid areas with oceanic climates, or when using highly hygroscopic compound fertilizers containing urea.

[Effect of idea]

As explained above, according to the broadcaster crushing device of the present invention, it is possible to remove the solidified powder and granules at the supply port position for supplying powder and granules such as fertilizer and seeds to the broadcaster, which takes time and effort. The crushing blade and receiving blade can completely crush and stir the powder, and therefore, smooth powder can be supplied to the hopper, improving scattering performance and reducing labor and labor savings.
