Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a threshing machine in which, for example, a threshing device can be moved by a crawler.

(Prior Art) Conventional threshing machines simply have a rice bundle stand attached to the side of the threshing device, so at least two people are required to thresh the rice. In other words, one person would place the rice bundles on the rice bundle table, and then another person would place the rice bundles through a feed chain and thresh them one bundle at a time.

(Problems to be Solved by the Present Invention) The present invention has been made in view of the above-mentioned points, and its purpose is to place rice bundles on the rice bundle mounting table and then automatically do the rest. The grain can be sent to the threshing machine to be threshed.
Furthermore, we provide a threshing machine that can perform general feeding and threshing smoothly.

(Means for Solving Problems, Effects, and Examples) The present invention will be described in detail below based on an example of a harvester. The barhester is equipped with a threshing device 2 at the front and an operating section at the rear, and can be moved by crawlers 8. The threshing device 2 has a built-in threshing barrel 9 and has a supply port 3 opened on one side. Further, a feed chain 6 is disposed parallel to the rotating shaft of the saw barrel 9, and the feed chain 6 grasps the lightning B of the rice bundle A and moves it from the supply port 3 in the discharge direction before threshing. ing. The feed chain 76 consists of a chain body and a support body disposed close to the lower outer periphery of the chain body, and is structured to move the rice bundle A with the stock B sandwiched between them.

Reference numeral 5 denotes a rice bundle mounting table, which is formed into a funnel shape with a flN slope I8, and a rice bundle outlet 17 is opened at the bottom of the rice bundle mounting table 5 toward the rear. This rice bundle mounting stand 5 is arranged on one side of the machine body l and protrudes laterally from a position in front of the supply port 3 of the threshing device 2. And rice bundle A
The grains are placed on the rice bundle mounting table 5 with the ears C facing toward the machine body l, and are sent to the bottom along the slope I8. Furthermore, if a feeding conveyor is attached to the rice bundle mounting table 5, this feeding becomes even more reliable.

Reference numeral 20 denotes a conveyance means, and the conveyor a20 is constructed by arranging a plurality of conveyance bands 7 (three conveyance bands 7a, 7b, and 7c in the illustrated embodiment) in a linear manner, and the starting end thereof is a rice bundle takeout port. 17, and connect the end to the feed chain 6.
It is located at the tip of the Protrusions 12 on the outer periphery of each conveyor belt 7
The chain 13 is made up of a chain 13 and a lower holding body 14 arranged in parallel below the chain 13. Then, by the rotation of the chain 13 of the conveyor belt 7 next to the rice bundle mounting table 5, the rice bundles are pushed between the chain 13 and the lower clamping body 14 with the protrusions 12, and the rice bundles are removed from the rice bundle mounting table 5. A is pulled out and conveyed to the supply port 3 of the threshing device 2 by each conveyor band 7.

FIG. 3 shows the conveying means 20 in which the conveying speed of the conveying belt 7 that is closer to the supply port 3 of the threshing device 2 is faster. In this embodiment, sprockets 16 having different diameters are coaxially rotated to change the conveying speed. Therefore, each time the rice bundles are transferred from one conveyance belt 7 to the next conveyance belt 7, the distance between adjacent rice bundles A increases and the rice bundles A are separated.

A transport belt 7 located next to the rice bundle loading platform 5 among each transport belt 7
A is designed to be able to swing around one end, as shown in FIG. 1, so that the position of the stock B can be adjusted. As a result, if the rice bundle A is long (for example, 1201) w*
), even if it is short (for example, 600+is), you can always make one bet on the stock price. Incidentally, the tip C is always placed in contact with the vertical wall 15 on the side of the machine body of the rice bundle mounting stand C.

In addition, the conveyor belt 7 located on the side of the supply port 3 of the threshing equipment 7F, 2
C is designed to be able to swing around one end as shown in FIG. 1, so that the insertion depth of the threshing device 2 into the saw barrel 9 can be changed. This allows threshing to be done in accordance with the area where the ears of rice bundle A are attached.

Reference numeral 19 in FIG. 1 is an auxiliary conveyance device formed by a conveyor or the like, and the tip C of the rice bundle A is placed on this auxiliary conveyance device 19 and conveyed. As a result, the conveying means 2
This eliminates the delay in the tip C that occurs during the transportation of the stock B in the middle of 0, and also allows the tip C to be handled. Therefore, the conveyance speed of the auxiliary conveyance device I9 is set so that the tip C precedes the first day of the stock.

FIG. 1 shows the transport operation of the rice bundle A.

First, the rice bundle A is placed on the rice bundle mounting stand 5. Then, the rice bundle A is moved along the slope 18 to the rice bundle take-out port 17 as shown by arrow A. Grasp the grain and transport it to the supply port 3 of the threshing device 2 as shown by the arrow. At this time, the rice bundle A is turned around around the tip C, and the stock is pulled upwards, allowing the rice bundles to be efficiently separated from each other and brought to the supply port 3. Moreover, at this time, the tip C is lowered. It becomes easier to put the grain into the threshing device 2. Finally, the grain is threshed by moving it in the direction of arrow C using the feed chain 6.

As described above, the present invention protrudes laterally from a portion in front of the supply port opening on one side of the threshing device, and the rice bundle mounting platform protrudes from the protruding ring and the starting end of the feed chain of the threshing device. A conveying means for conveying the lightning by sandwiching it between them is installed, and this conveying means has a plurality of conveying belts lined up in a line with an angle of 4 degrees, making it possible to automatically feed rice bundles from the rice bundle loading platform to the threshing device. It is possible to save labor, and the rice bundles can be fed to the threshing device at regular intervals, resulting in good threshing efficiency and stable performance. Since the conveying belt increases the conveying speed, each time the rice bundles are passed from one conveying belt to the next, the distance between adjacent rice bundles increases and the rice bundles are separated. It has the effect of being able to In addition, the conveyor belt at the back of each conveyor belt, next to the rice bundle mounting table, is designed to be able to be adjusted by one position in order to change the position in which the rice bundles are held, so that the rice bundles can always be gripped whether the rice bundles are long or short. It has the effect of being able to. Furthermore, the position of the conveyor belt next to the feed chain of each conveyor belt is adjustable in order to change the depth of insertion into the threshing device, so it can be threshed according to the range where the ears of rice bundle A are attached. This effect is achieved.
