Patent Document 1, as described above, is configured to discharge the stem to the both sides of the stationary body when the stem is lifted by the crushing wheel, when the crushing wheel rotates when cutting the stem dust and the stem is cut As dust generated by the dust is scattered together, even if there is an emission preventing curtain, the dust is emitted, causing contamination of the entire work area as well as around the apparatus due to the discharge of fine dust.

As such, the surrounding area and the work area are contaminated with fine dust, which may cause workers' respiratory diseases, and when the work area is in a position adjacent to the authorization, it is not free from complaints caused by scattering dust.

While the crushing wheel rotates, it causes the wind to cut down the stem while raising the stem, but in practice it is difficult to erect the collapsed stem due to the limitation of the speed at which the crushing wheel rotates. Outgoing stems often pass by not being cut.

In this way, since the entire stem of the crop planted in the toad is not cut cleanly, a separate worker needs to work after cutting the uncut stem while moving along the toad through the device. It is difficult to achieve the fundamental purpose of doing so.

Even when the stem is delivered by the crushing wheel and discharged to both sides of the toad, the stem is often kept in a long length without being cut small, so it is not discharged smoothly. The work must be done, making efficient work difficult.

If the height adjustment is made incorrectly in the process of cutting the stem by the crushing wheel, the upper part of the crop is cut down to reduce the value of the product. In addition, when the crushing wheel collides with foreign matter such as twigs or stones remaining on the tofu, Foreign substances and damaged crushing wheels are scattered to the outside of the device, and there is a high possibility of a safety accident.

In the present invention, to solve the problems as described above, the frame 103 is configured by connecting the gap retaining bar 102 to the front, rear side of the upper side of the side plate 101 to maintain the same width as the ridge;

A gear box 104 installed at a central portion of the frame 103 so as to receive a power war from a farm machine;

An upper connecting rod 105 and a lower connecting rod 106 provided on the gap maintaining bar 102 so as to be connected to agricultural machinery;

A stem cutting part 110 installed to cut a stem of a crop planted in a two-sided front of the frame 103;

A stem collection unit 150 installed above the stem cutting unit 110 to walk and cut the cut stem and to supply it to the rear;

A stem crushing unit 160 installed at the rear of the stem collecting unit 150 to crush the collected and crushed stems into small sizes;

A stem discharge part 170 installed at the rear of the stem crushing part 160 to discharge the crushed stem between the ridge and the ridge through one side of the frame 103;

There is no hassle to re-arrange harvested crops by cutting at the position as close as possible to the crop in the form of trimmer, and there is no scattering of dust and foreign substances in the process of cutting and cutting the stem. It is possible to achieve the purpose of keeping crops comfortable while keeping pleasant and not causing the crushing stem to be discharged.

According to the present invention, when cutting a stem of a crop by using a trimmer-type stem cutting unit such as a bariccan, the cut stem is crushed into a small size and discharged between the toad and the toad so that efficient work can be performed without the uncut stem. It is possible to increase the quality of the device and have the advantage that can be the advantage of the external competitiveness.

In the present invention, the stem is cut and shredded into small sizes so that there is no post-work to collect or cut the cut stem, and because the cutting height is free to move according to the state of the cut, unnecessary adjustment work is not required. In the shredding and discharging process, there is no scattering of dust and foreign substances and the noise is small, and thus the invention has various effects such as maintaining a pleasant working environment.
