Description

[Detailed description of the invention] The present invention arranges a pair of left and right conveyors, each equipped with a plurality of protruding claws, so that the shell culm is conveyed toward the rear of the fuselage in the path inside the fuselage where they face each other. The present invention also relates to a tip conveying device configured to wrap the conveying planes of the protruding claws of both conveying bodies in a state close to each other in the vertical direction on the rear side of the path, and to merge the conveying shell culm tip sides at the lapped portion.

As mentioned above, by lapping the conveying planes of the protruding claws close to each other in the vertical direction, it is possible to smoothly merge the culms while locking substantially the same phase points on the tip side of the culms, which is preferable.

However, in the past, the protruding claws of a pair of left and right conveyors were arranged so that they were brought close to each other and wrapped so that the conveyance planes were almost parallel to each other on the rear side of the conveyance path so that the culms merged. Due to loosening or vibration of the attached conveyor, the left and right protruding claws interfere with each other at the lap portion, making it impossible to smoothly merge and convey the culms and causing abnormal noise.

The purpose of the present invention is to eliminate the above-mentioned drawbacks by simple modification, and an embodiment of the present invention shown in the drawings will be described below.

1 is a 3-row cutting combine; 3 is a raising device that uses a chain with raising claws 2 to raise a fallen culm;
Reference numeral 4 denotes a reaping section provided at the rear of the pulling device 3. A clipper-type cutting blade 5. It is composed of a cutting blade driving rod 6, an arm 7, etc., and the rod 6 and arm 7 are actuated from a prime mover (not shown in Figure 1) via a transmission mechanism 8, and the culm is cut in an upright state with a clipper type cutting blade 5. Reference numeral 9 denotes a threshing unit 10 in which the husks are harvested in an upright position by the reaping unit 4.
a conveying section for conveying to a loading wheel 11. ．．
11.11, a stock transport device 14 consisting of two transport shapes 12.13, and two transport bodies 1 with protruding claws 15...
6.17, and a lifting conveyor 20 that transfers the culm from the stock head conveyor 14 to the starting end of the feed chain 19 of the threshing section 10.

The scraping wheels 1i, ii, 1i, stock transfer device 1
4. Spear tip conveying device 18. The lift carrier 20 is configured to be operated by an external motor via a transmission mechanism 18.

Furthermore, the two conveyors 16 and 17 that constitute the tip conveyor 18 are as follows.

The reaped husk culm is arranged to be conveyed toward the rear of the machine on the internal routes facing each other, and the conveying planes of the protruding claws 15 of both conveyors 16 and 17 are aligned vertically with respect to each other on the rear side of the route. They are wrapped in a state in which they are brought close to each other, and the wrapped portion is used as a merging point P to merge the conveyed shell culm tip side, and after the merging point P, the conveying route backward from the merging point P is configured. The confluent culm is conveyed toward the supply port 21 of the threshing section 10 by a conveyor 16 having one conveyor 17 located on the lower side in the lap portion, as shown in FIG. With respect to the conveying plane of the protruding pawls 15, the conveying planes of the protruding pawls 15 of the conveying body 17 located above the wrap portion are inclined in such a manner that the tips of these pawls are separated from the protruding pawls on the lower side. It is a provision.

In addition, 22 is a handling cylinder. Next, the operation of the above embodiment will be explained.

While the combine 1 is traveling, the grain culm is raised by a raising device 3 and the grain culm is harvested in an upright state by a reaping part 4.

The harvested culm is transported to the starting end of the feed chain 19 on the stock side using the stock transport device 14 and the lifting conveyor 20, and on the ear side to the supply port 21 of the threshing section 10 by the ear tip transport device 18. The shell culm is fed to the threshing section 10 in a horizontal position.

By the way, in the two conveying bodies 16 and 17 that constitute the ear tip conveying device 18, the cut culm is transferred to the conveying bodies 1.
The tips of the culms carried by one carrier 17 are also transported by the other carrier 16 after the confluence point P of the carriers 16 and 17.
The conveyor 16 conveys the grains to the supply port 21 of the threshing section 10 on the tip side of the culm.

As described in detail above, the present invention provides a method for transporting the protruding claws located above the conveyance plane of the protruding claws located below the wrap portion of the protruding claws that join the grain culm tips. By tilting the conveying plane so that the tip of the claw is separated from the lower protruding claw, the upper protruding claw is less likely to interfere with the lower protruding claw even if the conveyor loosens or vibrates. As a result, grain culms can be smoothly merged without causing postural holes, and abnormal noises can be suppressed.
