Description

[Detailed Description of the Invention] The present invention relates to a self-propelled thresher that can be loaded and unloaded.

Conventionally, in a self-propelled threshing machine, the threshing machine is placed on a self-propelled trolley so that it can be loaded and unloaded, and when threshing is finished, the threshing machine slides on the trolley using rollers installed on the underside of the threshing machine, and one end is grounded. After making it into an inclined shape and fixing it with a stand, the threshing machine is separated from the self-propelled cart.

The self-propelled cart from which the threshing machine has been removed is used as a transport vehicle.

However, when a threshing machine is installed at an angle with a stand upright, the stand may sink into the ground while it is left unattended, and when this happens, the rollers installed on the bottom of the threshing machine will fall below the top of the trolley, making it difficult to thresh. It becomes impossible to insert the trolley into the machine from below, making it difficult to load it.

Also, when the threshing machine slides on the cart, the rollers slide too lightly, causing it to be thrown off with such force that the threshing machine falls to the ground before the stand can be erected, causing the rollers installed on the underside to collide with the ground and break. Sometimes I put it away.

The present invention was proposed to solve the above-mentioned drawbacks, and its characteristics are that a self-propelled cart is equipped with rollers that can be moved in height using a swinging arm, and the threshing machine is mounted on the cart. product·
At the time of unloading, the rollers are positioned lower than the top of the cart to facilitate loading, and the rollers are operated with the threshing machine tilted to facilitate loading and unloading.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall side view of a self-propelled threshing machine. In this self-propelled threshing machine 1, a threshing machine 5 is mounted on a front half 4b of a self-propelled cart 4 which rotates a crawler 3 using the power of an engine 2. It is mounted and fixed.

The self-propelled trolley 4 has a slide rail 6 fixed to the upper surface 4c of the front half 4b, and a hook 8 is provided at the rear end of the slide rail 6 to hold down the rear upper surface of the bottom frame 7 of the threshing machine 5. A roller moving/fixing device T is provided which presses and fixes the front upper surface of the bottom frame 7 of the threshing machine 5.

In this device T, a swinging arm 10 is pivotally supported on the left and right sides of the front part of a truck 4, and a roller pivot shaft 11 is fixed to the swinging arm 10.Rollers 9 made of bearings are fixed to the swinging arm 10 on the left and right sides. It is centrally supported.

After the threshing machine 5 is placed on the self-propelled trolley 4, the roller moving/fixing device T automatically moves a tightening plate 12 provided parallel to the roller pivot shaft 11 between the left and right swinging arms 10. The running truck 4 is fixed by tightening a nut 14 onto a bolt 13 protruding from the front end.

Further, a towing hook 15 is fixed to the lower surface 4a of the front end of the self-propelled trolley 4 with a bolt 16.

The front half of this hook 15 is made to protrude forward from the front end of the self-propelled trolley 4, and the swinging arm 1 of the roller moving/fixing device T
0 is adapted to receive the roller pivot shaft 11 and the clamping plate 12 when it is swung downward.

In addition, the code|symbol 17 is a culm supply stand, and when loading and unloading the threshing machine 5 from the self-propelled trolley|bogie 4, it is folded.

That is, as shown in FIG. 5, this culm supply table 17 is supported in a swinging posture A and a horizontal posture B by flipping upward using the upper part of a support frame 18 fixed to the side surface of the threshing machine 5 as a fulcrum P. A spring 20 interposed between the frame 18 and the support pipe 19
The structure is such that it can be switched and swung by the culm supply stand 17, and when it is folded upward with the shell culm supply stand 17, it is locked in the folded position by the fixing rod 21.

One end of the fixed rod 21 is swingably supported by the culm supply table 17, and a circumferential groove 22 is provided in the middle portion of the other end, which is shaped like a thick rod.

A receiving part 23 that receives this circumferential groove 22 is a part of the culm supply stand 1.
A U-groove 26 is provided at a place where the tip of a stopper 25 of a guide pipe 24 that guides the shell culm supplied from 7 is bent.

Next, the procedure for loading and unloading the threshing machine 5 from the cart 4 will be explained using an example.

First, after flipping up the shell culm supply stand and firmly locking it with the fixing rod, screw the nut 14 that tightens the tightening plate 12 of the roller moving/fixing device T provided at the front end of the self-propelled trolley 4. Then, the swinging arm 10 is swung downward and the hook 15 is stopped.

Next, the bottom frame 7 provided at the bottom of the threshing machine 5 is slid on the rail 6 provided on the top surface 4c of the self-propelled trolley 4 to project the threshing machine 5 forward from the trolley, and the front end of the bottom frame 7 is placed on the ground. Ground to G.

At this time, the stand 27 provided on the lower surface of the rear half of the bottom frame 7 rises up and is biased by the spring 28 and comes into contact with the ground G (FIG. 2).

After this, when the self-propelled cart 4 is moved backward, the separation (unloading) between the threshing machine 5 and the self-propelled cart 4 is completed.

Furthermore, when loading the threshing machine 5 onto the self-propelled trolley 4, the operation is completely reversed to the above procedure example, and when the tightening plate 12 of the roller moving/fixing device T is tightened and fixed with the nut 14, the swinging arm 10 is drawn toward the self-propelled cart 4 side, and the lower surface of the roller 9 presses the upper surface of the bottom frame 7 of the threshing machine 5 to firmly fix it.

The present invention is structured and operates as described above, and has the following effects.

(b) Even if the stand sinks into the ground and the bottom frame becomes lower than the top surface of the self-propelled trolley while the threshing machine is placed on an inclined position with the stand erected, the rollers will be positioned lower than the top surface of the self-propelled trolley. The bottom surface of the bottom frame of the threshing machine can be scooped up correctly, and the threshing machine can be easily and quickly loaded onto a self-propelled trolley.

(b) Since the rollers also serve to fix the threshing machine to the mounting base, the structure is simple and can be implemented at low cost.

(c) When unloading the threshing machine from the mounting platform, the threshing machine is separated from the rollers, slides on the rails, moves gently on the mounting platform at an appropriate speed, runs too fast on the rollers, and suddenly drops to the ground. When one end of the bottom frame of the threshing machine protrudes from the mounting base and touches the ground, the stand will be properly supported by the spring from the bottom of the threshing machine, and when the cart is pulled back from this state, the threshing machine will move to the stand. It can be properly propped up on the ground while being maintained in a tilted position.

Therefore, neither the bottom nor the rollers of the threshing machine will be damaged due to sudden slamming into the ground, resulting in excellent durability.
