Description

[Detailed description of the invention] This invention relates to a tractor straw collection machine that collects waste straw after combining.

With the recent development of harvesting operations using combine harvesters, the disposal of waste straw left in fields has become a problem.

This is because if waste straw is left as it is, it will rot and produce malignant gas that hinders the growth of rice, and if it is incinerated, it will generate smoke pollution.Therefore, the best method is to collect waste straw and feed it to dairy cows. It is used as feed.

However, conventional straw collectors have multiple rotary rakes mounted in the frame, making the frame large and unsuitable for small fields like Japan. The waste straw is collected in a line on one side using a rotary rake with multiple stages of transport rods, and the waste straw collected in a single line must be transported to one more location. There was a drawback that required

The object of this invention is to provide a tractor straw collector that can eliminate the above-mentioned drawbacks.

Next, the structure and operation of this invention will be explained with reference to the drawings.

Three-point linkage mechanism 2 provided at the rear of the tractor 1
An L-shaped frame 3 is connected to the lower end of this frame 3, and the lower surface of a packet 4 is pivoted 5 to be able to vibrate rearward, and the base of a claw body 7 having a lever 13 is pivoted 8 on the upper surface of this frame 3. At the same time, a downward tension spring 9 is provided in front of the claw body 7, a roller 11 is provided on the upper surface of the front wall 10 of the packet 4 that engages with the claw body 7, and a stopper 12 is provided to restrain the claw body 7 at a predetermined angle. is provided, and this claw body 7 and bucket I
・A locking mechanism 15 is formed by providing levers 13 and 14 on the front wall 10 of the packet 4, and a plurality of tooth rods 17 are protruded at equal intervals from the bottom plate 16 at the rear of the packet 4, that is, the opening, to form a rake a. A tooth rod 17 is provided at the outer lower part of the left and right side walls 18 of the packet 4.
An arm 19 of approximately the same length as the packet 4 is protruded, and a grounding member 20 is provided below the tip of the arm 19.The length in the traveling direction of the packet 4 may be short, and the tooth rod 17 is similar to the packet 4. It is preferable to fix it to the top surface of the bottom plate 16.

In addition, the arm 19 may be provided on only one of the left and right side walls 18, and the tooth rod 17 preferably has a sharp tip.

As shown in FIG. 2, the frame 3 and packet 4 are lowered by the three-point linkage mechanism 2, the grounding member 20 is brought into contact with the ground, and the toothed rod 17 is brought into almost the grounded state, and the tractor 1 is moved backwards, thereby scattering the seeds in the rice field. The waste straw is introduced into the packet 4 by a plurality of tooth rods 17.

Next, after the waste straw is stored in the packet 4, the link mechanism 2
As shown in FIG. 3, the frame 3 and packet 4 are raised and the tractor 1 is driven to a predetermined straw collection location. When the straw collection location is reached, the lever 13 of the claw body 7 of the locking mechanism 15 is pulled to release the claw. The body 7 and the roller 11 are disengaged.

Then, the packet 4 vibrates backward and the straw inside the packet 4 is discharged.

Next, when the frame 3 is lowered by the link mechanism 2, the packet 4 gradually becomes horizontal as shown in FIG. 4, and the roller 11 and the claw body 7 are automatically locked.

In this case, the packet 4 can be more easily locked by pulling the lever 14.

Furthermore, the plurality of tooth rods 17 are protected because the grounding member 20 of the arm 19 comes into contact with the ground when the packet 4 vibrates during unlocking and when the packet 4 rotates when locking.

Conventional straw collecting machines have multiple rotary rakes mounted on the frame, and the rotation of the rotary rakes collects and transports the waste straw in a line on one side, which makes the frame large, making it inconvenient to operate and causing problems after collection. Although there was a drawback that the waste straw collected in a line had to be further processed and required double labor, this invention has a plurality of tooth rods 17 and arms 19 in a packet 4 that is short in the direction of travel. Since it is formed in a protruding manner, compact and efficient operation is possible.

Unlike the rotary rake that scatters waste straw and collects it, the tooth rod 17 protruding from the packet 4 directly introduces waste straw into the packet 4 and stores it there, so it is possible to collect the waste straw easily in one straw collection operation. It becomes possible to perform extremely effective work by effectively using the space in space a.

In addition, the straw can be discharged with one touch by opening and closing the lock mechanism 15, which has an excellent practical effect.

In addition, the conventional straw collecting machine, as disclosed in Japanese Utility Model Application Publication No. 48-47726, has tip claws protruding from the rear end of the shelf-like bottom at predetermined intervals, and the tip claws are rotatable to raise the main body above the ground. Know what to use.

It has been pointed out that in such conventional technology, the main body itself is inclined with respect to the ground due to the plurality of tip claws, and the straw collection performance as a whole is somewhat inferior.

However, in the present invention, the arms 1 are placed on both sides of the rear of the packet 4.
By protruding the arm 19 and providing the grounding member 20 on the lower surface of the arm 19, the rake a always travels parallel to the ground.
It has excellent practicality as it can be used to collect straw.

In addition, as known from Japanese Utility Model Application No. 48-47726, the conventional straw collecting machine has a fence-like bottom, which causes the problem that the straw once collected falls down while the tractor is running.

However, in the present invention, since the rake a consisting of a tooth rod 17 is provided on the opening side of the packet 4 consisting of the front wall 10, the bottom plate 16, and the left and right side walls 18, the straw collected by the rake a is It is stored in 4.

Therefore, in the present invention, there is no risk that the straw once collected will fall as the tractor 1 travels, unlike in the prior art.

Furthermore, in the present invention, an L-shaped frame 3 is attached to the rear of the tractor 1 via a three-point linkage mechanism 2, and the lower surface of the packet 4 is pivoted to the lower end of the frame 3 so as to be able to vibrate rearward.
It is provided.

Therefore, when the work is completed, the packet 4 is vibrated backward, tilted, and automatically discharged, which is an excellent feature.

Furthermore, in this invention, a three-point linkage mechanism 2 is installed at the rear of the tractor 1.
An L-shaped frame 3 is attached to the lower end of the frame 3 and a packet 4 is pivoted 5 to the lower end of the packet 4 so that the lower surface of the packet 4 can vibrate rearward.

Therefore, when the work is completed, the packet 4 is vibrated backward, tilted, and automatically discharged, which is an excellent feature.
