Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a straw scooping device in a straw collecting machine that scoops and collects straw scattered in a field.

Generally, straw that has been harvested and threshed with a combine harvester and discarded scattered around the field is burned in the field, and the smoke causes pollution problems.

Therefore, straw scattered in fields is collected and piled up for composting, or packaged and used as feed supplement to avoid pollution.

In the conventional rice straw collecting machine, a plurality of straw scooping rods are fixedly installed at the lower front part of the tract and protrude horizontally in parallel, and the straw is scooped up by the straw scooping rod as the tract moves forward. The purpose is to collect straw scattered in the fields.

However, because the top surface of the field is undulating and the rice plants are scattered, when scooping up the scattered straw with the straw scooping rod, the straw scooping rod may penetrate into the convex parts of the top surface of the field or into the rice plants. In this case, not only the straw to be collected but also the mud etc. must be scooped out, making it impossible to scoop the straw smoothly.In order to avoid forced penetration, the height of the straw scooping rod can be raised, but this does not work. There was a problem that the straw recovery rate was poor and work efficiency was reduced.

The present invention aims to provide a straw scooping device for a straw collecting machine that can eliminate these inconveniences.

The present invention will now be described with reference to the accompanying drawings.

A machine frame 2 is connected to the traveling machine body 1, and a plurality of straw scooping rods 11 are protruded in parallel in the horizontal direction from the lower part of the machine frame 2.
In a straw collecting machine that scoops and collects scattered straw with the straw scooping rod 11 due to the running of the straw, a clamping link mechanism 12 is disposed at a connecting portion 15 between the straw scooping rod 11 and the machine frame 2, The pressure link mechanism 12 presses the straw scooping rod 11 against the upper surface of the field, and the straw scooping rod 11 is configured to float backward due to resistance such as irregularities on the upper surface of the field.

This example will be explained.

In this embodiment, the lower links 5 protruding from the left and right sides of the rear part of the traveling body 1 are pivotally connected to the left and right vertical rods 4 of the machine frame 2, and the traveling body 1 is connected to the middle of the upper horizontal beam 6 of the machine frame 2. An upper link 7 protruding from the center of the rear upper part of the traveling body 1 is pivotally connected, and a swinging arm 8 protruding from the left and right sides of the rear upper part of the traveling body 1 and the middle of the lower link 5 are pivotally connected by a lifting link 9. The machine frame 2 is connected to the machine frame 2 so as to be movable up and down by the swing motion of the swing arm 8.

Further, in this embodiment, a horizontal mounting bar 3 is provided at the bottom of the machine frame 2.

The elastic link mechanism 12 of this embodiment is an application of a parallel link mechanism, in which a plurality of support arms 17 are fixed to the mounting crosspiece 3 in the front and back direction, and a pair of forearms 14 are attached to the front and rear of the support arms 17. The upper part of the forearm 14 and the upper part of the pair of rear arms 13 are each pivotally suspended, and the lower part of the forearm 14 and the lower part of the rear arm 13 are each pivotally connected to the base of the straw scooping rod 11. The tip of the rod 11 is formed into a sharp point 10, and an elastic grounding spring 16, which is a tension spring, is suspended between the support arm 17 and the straw scooping rod 11. At all times, the straw scooping rod 11 is pressed against the top of the field, and when traveling, the straw scooping rod 11 comes into contact with irregularities in the field, rocking pillows, etc., and the sharp portion 1
0 receives running resistance, the straw scooping rod 11 moves backward while moving upward against the spring 16 for elastic grounding, and when the unevenness disappears, the straw scooping rod 11 is lifted by the spring 16 for elastic grounding. moves downward and then repeats the vertical movement.

As described above, in the present invention, a pressure link mechanism 12 is disposed at the connection part 15 between the straw scooping rod 11 for scooping straw and the machine frame 2, and the pressure link mechanism 12 allows the straw scooping rod 11 to be moved in the field. Since the straw scooping rod 11 is configured to press against the upper surface and move backward and upward due to resistance such as unevenness on the upper surface of the field, the straw scooping rod 11 is grounded on the upper surface of the field and the traveling machine body 1 is caused to travel backward. If so, the straw scattered on the top surface of the field can be scooped up and collected with the straw scooping rod 11. Especially, since the straw scooping rod 11 can float and move when traveling to scoop up straw, the straw scooping rod 11 can be When it collides with a convex part of the field, a rocking pillow, etc. and receives running resistance, it can levitate and escape, which prevents forced entry, making it easier to scoop straw along the irregularities. The rod 11 can be scooped up and run, and the straw collection work can be carried out smoothly and efficiently.

In addition, the straw scooping rod 11 in particular does not simply float up, but floats while retreating, so it can escape and float in the direction of passing through the protrusion or rocking pillow, etc., which has been pierced, thereby making the straw scooping operation even better. This allows for smoother running and improves the efficiency of straw collection work.

As described above, the intended purpose can be fully achieved.
