Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to (1) a straw scooping device in a straw collecting machine that scoops and collects straw scattered in a field.

In general, straw that has been harvested and threshed with a combine harvester or the like and scattered and discarded in the field is burned in the field, and this combustion 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 conventional seed straw collection machines, multiple straw scooping rods are fixedly installed in the lower front part of the tractor and protrude horizontally in parallel, and the straw is scooped up by the straw scooping rods as the tractor moves forward. The purpose is to collect straw scattered in the fields.

However, since the top of the field is undulating and the rocking pillows are scattered, when scooping up the scattered straw with the straw scooping rod, the straw scooping rod may penetrate into the protrusions or rocking pillows on the top of the field. In this case, not only the straw to be collected but also the same size of mud is 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 is not possible. However, 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 12 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 12 as the straw travels, a suppression mechanism 15 is disposed at the connecting portion 17 between the straw scooping rod 12 and the machine frame 2, and The straw scooping rod 12 is pressed against the upper surface of the field by the compression mechanism 15VC, and the straw scooping rod 12 is moved backward and floating due to resistance such as unevenness on the upper surface of the field, and is attached to the machine frame 2. A position regulating rod 1 that prevents the straw scooping rod 12 from penetrating into the inside of the field.
0 is fixedly provided in a protruding manner.

This example will be explained.

In this embodiment, 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 An upper link γ 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. However, the machine frame 2 is connected to the machine frame 2 so as to be freely raised and lowered by the swinging motion of the swinging arm 8.

In this embodiment, the mounting horizontal transfer 3 is provided at the bottom of the machine frame 2,
A straw scooping rod 12 and a position regulating rod 10 are connected and attached to this mounting horizontal movement 3.

The compression mechanism 17 of this embodiment applies a parallel link mechanism, in which a plurality of support arms 18 are fixed to the horizontal mounting 3 in the front and back direction, and a pair of forearms 13 are attached to the front and rear of the support arms 18.
The upper part of the forearm 13 and the upper part of the pair of rear arms 14 are pivotally suspended, and the lower part of the forearm 13 and the lower part of the rear arm 14 are attached to the straw scooping rod 1.
Each of the straw scooping rods 12 is pivotally connected to the base of the support arm 18 and the straw scooping rod 12 is formed into a sharp point 11 .
In other words, the straw scooping rod 12 is normally biased against the upper surface of the field by the elastic grounding spring 16, which is a tension spring. When the straw scooping rod 12 comes into contact with a rocking pillow or the like, and the sharp part 11 receives running resistance, the straw scooping rod 12 moves upwardly while retreating with the parallel link mechanism against the elastic grounding spring 16. etc., when the straw scooping rod 1 is removed by the spring 16 for pressure grounding.
2 moves downward and repeats the vertical movement.

The position regulating rod 10 of this embodiment is fixedly protruded in the horizontal direction in parallel with the straw scooping rod 12 on both left and right sides of the horizontal mounting 3.

As described above, in the present invention, the clamping mechanism 15 is disposed at the connection part 17 between the straw scooping rod 12 for scooping straw and the machine frame 2, and the clamping mechanism 15 allows the straw scooping rod 12 to be pushed onto the upper surface of the field. Since the straw scooping rod 12 is configured to move backward and upward due to the resistance of unevenness on the top surface of the field, etc., when the straw scooping rod 12 is grounded on the top surface of the field and the traveling body 1 is moved backward, Straw scattered on the top surface of the field can be scooped up and collected by the straw scooping rod 12. Especially, since the straw scooping rod 12 can float and move when traveling to scoop up straw, the straw scooping rod 12 can be used to collect the straw scattered on the top surface of the field. When it collides with a convex part, a rocking pillow, etc. and receives running resistance, it can levitate, that is, escape, thereby preventing forced penetration. The straw can be scooped up and moved, allowing for smooth and efficient straw collection work.

However, the straw scooping rod 12 in particular does not simply float up (because it floats up while retreating, it can escape in the direction of passing through the pierced protrusion or rocking pillow, etc., and float up, making the straw scooping action even better. Become.

Furthermore, since a positioning rod 10 is fixedly protruded from the machine frame 2 to prevent the straw scooping rod 12 from penetrating into the inside of the field, the straw scooping rod 12 is prevented from penetrating deeply into the inside of the field. At this time, the straw scooping rod 12 floats and escapes due to the pressure mechanism 15, but when the straw scooping rod 12 tries to penetrate into a convex part etc. until it escapes and floats, the position regulating rod is activated. 10 maintains the stable posture of the machine frame 2 and runs the straw scooping rod 12 along the convex portions, etc., so that the straw scooping rod 12 can be further prevented from penetrating, and the machine can run more smoothly. This can improve the efficiency of straw collection work.

The above intended objectives can be fully achieved.
