Description

[Detailed description of the invention] The present invention relates to a pressing roller for barley treading, which is attached to a stock-filling machine for working with barley.

In wheat cultivation, in order to produce strong wheat with good rooting, it is necessary to tread the wheat and add soil in the winter months of January and February. Conventionally, soil was poured with a small tiller, and then a roller was rolled to tread the wheat, which was a two-step process, but with this invention, treading the wheat and treading the soil are done simultaneously with one machine. be.

Rollers are attached to the axle instead of tires, and instead of a rotary tiller, an up-cutting soil-filling device is installed to lift soil from the furrows and drop it onto the wheat.

In this type of wheat management machine, the outer diameter of the roller is flat so as not to damage the wheat leaves, so it is not possible to obtain propulsion like a tire, and on the contrary, it is difficult to install a soil container. The problem was that because the aircraft was rotating sharply, it tried to stop the control aircraft, and the aircraft ended up slipping and not moving forward.

In addition, in order to properly trample the wheat, the weight of the management machine of about 20 kg is not enough, and it is necessary to attach another weight of 50 kg or more to make the load on the rollers about the same as the ground contact load of the sole of a human foot. There is.

Conventionally, a 50Kg weight was placed in front of the engine frame as a front weight, but in terms of durability, the engine frame of the control machine was not designed to withstand a 50Kg weight.
The front frame was rattling due to repeated vibrations.

In order to eliminate these drawbacks, the present invention eliminates the front weight, and instead installs a 50 kg weight wheel on the axle and protrudes a lug on the outer diameter of the weight wheel, which cannot be obtained with rollers. It was also possible to obtain a driving force.

The purpose of the present invention is as described above, and the present invention will be explained based on the configuration of the embodiment shown in the attached drawings.

Figure 1 is an overall side view of the wheat management machine of the present invention.

Figure 2 is an overall bottom view of the wheat management machine.

FIG. 3 is a perspective view of the cover 9 of the soil filling device. The wheat management machine is mainly composed of a milling case 13, and a handle 12 is fixed to the upper part of the milling case 13. A front frame 15 is protruded from the front part of the transmission case 13,
An engine 14 is installed on the upper part of the front frame 15, and a stand 16 is installed vertically on the lower part.

Rotational force is transmitted from the engine 14 to the input shaft of the transmission case 13 by a belt, and a belt cover 18 is provided on the belt.

A soil container attachment is attached from the rear of the mission case via a hitch, and the soil container attachment consists of a cover 9, an upcut claw 10, and a tail wheel 17. An axle 6 protrudes from the lowermost left and right sides of the transmission case 13, and a weight wheel 1 and a roller 5 are symmetrically fitted onto the axle 6.

FIG. 4 is an enlarged cross-sectional view of the axle with the rollers 5 and weight wheels 1 attached.

FIG. 5 is a side view of the weight wheel 1.

FIG. 6 is a front sectional view of the weight wheel 1.
The weight wheel 1 is configured to have a slightly larger diameter than the roller 5, and a portion protruding from the outer diameter of the roller serves as a lug 1a for obtaining propulsive force.

It is also possible to attach a weight 2 for increasing the weight on the outside of the weight wheel 1. An extension axle 8 is fitted onto the axle 6 to extend the axle, and a roller 5 is fitted onto the extension axle 8.

The spokes 5a of the roller 5 can also be attached with the increase weights 3, and the increase weights 3 can also be attached with the increase weights 4.

As described above, the present invention attaches pressure rollers 5, 5 for barley treading instead of tires to the left and right axles,
In a barley treading machine that is equipped with an up-cut type soil container as a rotary tilling device at the rear, cast weight wheels 1, 1 are mounted on the transmission case side inside the barley treading pressure rollers 5, 5.
The portion of the weight wheel protruding from the outer periphery of the barley treading pressure rollers 5, 5 is configured as a lug 1a for obtaining propulsion force, so that the following effects are achieved.

First, lug 1a is attached to the outer diameter of the cast weight wheel.
The projecting structure provides propulsion, and this propulsion can also be used to pour soil.

Second, since the weight wheel itself has additional weight, there is no need to attach it to the front part of the engine frame as a front weight as in the conventional case, and the front-rear balance will not be disrupted.

Thirdly, there is no need to pass through the field twice for soil pouring and wheat treading as in the conventional method, and wheat treading and soil pouring can be done at the same time in one pass.

Fourthly, additional weights can be attached to the weight wheels themselves, making it possible to obtain sufficient suppressing force.
