Description

[Detailed description of the invention] This invention relates to a compost spreader that finely crushes and uniformly spreads compost onto rice fields, fields, pastures, etc.

Traditionally, compost has been put into practical use by loading it onto a trailer or the like, towing it to a destination with a small tractor, etc., and spreading it in the field, or by using a special-purpose compost spreading machine called a manas spreader.

However, in the above-mentioned compost spreader, the device that pushes the loaded compost to a part of the beater at the rear is not connected to the rotation or movement of the beater that spreads the compost, so the compost may be fed too quickly or too slowly, resulting in a thicker spread. There were drawbacks such as the fact that the coloring was not uniform.

In addition, it is not possible to spray compost or to fly it far,
In order to uniformly spread the spray over the entire field, it was necessary to go back and forth many times, resulting in poor work efficiency.

This invention was made in order to improve the above-mentioned conventional drawbacks, and by linking the compost feeding device of the compost spreading machine with the compost scattering device, the rotation of the compost scattering device allows for constant spreading thickness and spreading. To provide a compost spreader configured to secure the interior and spread as far as possible.

Hereinafter, one embodiment of this invention will be described in detail based on the attached drawings.

Figures 1 and 2 are a perspective view and a partially cutaway side view of the compost spreader according to this invention, in which 1 is a vehicle body, 2 is a hitch connected to a hitch part (not shown) of a tractor,
3 is a compost loading section provided at the rear of the vehicle body 1; 4 is a drive shaft to which power is transmitted from the tractor's power take-off shaft (not shown); 5 is a gear box; 6 is a crank; 7 is a crank arm; 8 is a one-way rotating gear, 9 is a moving wheel of the vehicle body 1, 10 is a compost scattering device, 11 is a compost feeding device, etc.

The drive shaft 4 applies a predetermined rotation to the crank 6 via a reducer in a gear box 5, and power is transmitted to a drive shaft 12 of a compost scattering device 10 via a belt, chain, or the like.

On the other hand, the rotation of the crank 6 gives intermittent rotation to the one-way rotating gear 8 via the crank arm 7, and is transmitted via the shaft 13 to the conveyor drive device of the compost feeding device 11.

The compost feeding device 11 has a feeding bar 14 as shown in FIG.
Both ends of the conveyor device 16 are connected by chains 15 at predetermined intervals.

In addition, a plate-shaped body 1 such as rubber or cloth is placed between the feed bars 15.
If line 7 is laid out, granular materials such as powder and sand can also be loaded.

A shutter device (not shown) is provided at the entrance of the compost sending device 11 and the compost scattering device 10, and is closed while compost is being loaded onto the loading section 3, and is opened when spreading begins. .

On the other hand, the compost scattering device 10, as shown in FIG.
A compost dispersion port 18 of the case body is provided on one side of the vehicle body 1, and a plurality of beaters 19 are provided radially fixed to a drive shaft 12 provided along the traveling direction.

This beater 19 crushes the compost sent during rotation and blows it away from the compost dispersion port 18, and the further away from the center of the drive shaft 12 the farther away the compost is scattered.

FIG. 5 shows another embodiment of the compost scattering device 10 according to this invention, in which, in addition to the large beater fixed to the drive shaft 12, a small beater device 20 for crushing the compost into finer pieces is provided near the compost inlet. This is an example.

The compost spreading device configured as described above is towed by a tractor or the like and receives driving force from a power transmission shaft, which rotates the beater of the compost scattering device, and one rotational force is transmitted to the compost feeding device via the crank and crankham. Since the structure is configured to drive the compost, the compost loaded in the compost loading section is sequentially sent to the inlet of the compost scattering device, and is crushed by the beater while being spread at a constant spreading thickness from near to far from the compost scattering port. is maintained and dispersed.

As explained in detail above, this invention has a simple structure and transmits the power from a tractor etc. to the compost feeding device and the compost scattering device. It is a constant and uniform process.

Further, granules can also be loaded by fixing a plate-like body made of rubber or cloth to the feed bar connected to the chain conveyor of the compost feeder.

In addition, the compost spreader of this invention rotates the beaters radially fixed to the rotating shaft at right angles to the direction of travel and opens the spread opening in one direction of the vehicle body, so the compost can be spread over a long distance and spread evenly from near to far. The practical effects are significant, such as the ability to spread compost, which further improves compost spreading efficiency and increases work efficiency.
