Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a threshing device for an all-cullet-type combine harvester in which a swinging and selecting section is provided rearward from the lower part of a handling room having a handling cylinder that rotates around the horizontal axis.

[0002]

[Prior art]

 Conventionally, as a threshing device for the above-mentioned all culm input type combine, it is general that the handling chamber and the swing sorting part are configured to have the same width, as shown in, for example, JP-A-63-56217. It is known that a control unit is provided on the side of the front of this threshing device.

[0003]

[Problems to be solved by the device]

 When constructing an all-cullet throw-in type combine with a small body width, the following problems will occur if the above configuration is followed as it is. In other words, if the control unit is made as wide as a large-scale machine while the machine width is regulated to be small, the width of the threshing device will be reduced, and threshing selection with the desired capacity will not be possible. On the contrary, if the width of the threshing device is set to a size capable of performing threshing selection with a desired ability, the width of the control unit becomes small and it becomes cramped. It is an object of the present invention to provide a threshing device that can be mounted on a relatively small all-cullet throw-in type combine with few defects.

[0004]

[Means for Solving the Problems]

 The characteristic configuration of the present invention for achieving the above-mentioned object is the threshing device of the all-cullet throw-in type combine described at the beginning, in which the lateral width of the handling chamber is set to be smaller than the lateral width of the rocking sorting section. , The handling room is arranged side by side to the side opposite to the control section present side with respect to the swing selection section, and the handling room and the control section are overlapped in a side view, and the front wall section of the handling room is arranged. From this, a sink plate is installed so as to swing up and down around the front end over the front part of the sorting case provided in the swing sorting part, so that the material to be leaked from the handling chamber is located in the front part of the sorting case. It is configured so that it can be supplied downstream.

[0005]

[Action]

 According to the above configuration, the handling chamber is set to have a width smaller than the lateral width of the swing selection unit, but it is possible to achieve the desired threshing ability by adjusting the rotation speed of the handling cylinder and the design of the handling teeth. The dynamic sorting section can utilize the wide width to exert the desired sorting ability. By arranging the control parts overlapping on the lateral side of the narrow handling room, it is possible to secure a control part with a lateral width that is not cramped even when the lateral width of the airframe is restricted. Also, the processed material that has leaked from the receiving net of the small width handling chamber is temporarily received by a sink plate of approximately the same width as the handling chamber, and is vertically fed to the front of the wide sorting case by swinging the sink plate up and down. Therefore, for example, a sorting case extending from the lower part of the handling room to the swing sorting section is formed, and a grain pan for receiving the processed material leaked from the net is installed in the front part of the sorting case to sort the processed material as a whole. The sorting case can be made lighter and smaller than the case where the swing feeding operation is performed, and it is effective in reducing the vibration that is inevitable by the swing sorting means. Further, by simply connecting the rear part of the sink plate to the front part of the sorting case by engaging or placing it, the swing plate can be easily swung up and down in conjunction with the forward and backward swing of the sorting case. However, there is no need for a drive means dedicated to the sink.

[0006]

[Effect of device]

 As is clear from the above description, the present invention does not make the control section cramped and impairs the threshing selection function when constructing a relatively small all-cullet throw-in type combine in which the body width is restricted. It was possible to obtain a practically useful threshing device that can be installed without any need, and that is small and lightweight, and can be implemented with comparatively little vibration.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an overall side view of a threshing device for an all-cullet-type combine harvester according to the present invention. This all culm throwing type combine is a threshing device that connects a cutting unit 3 to the front part of a traveling body 1 having a pair of left and right crawler traveling devices 2 so as to be able to move up and down, and threshes and selects grain culms from the cutting unit 3. 5, the control unit 4 and the like are mounted in parallel on the traveling body 1. The reaping unit 3 collects a reel 6 for scraping planted culms to the rear of the machine frame 1, a reaper 7 for reaping the scraped culms, and an auger 8 for collecting the corns in the middle of the cutting width. A feed conveyor 9 or the like for feeding the grain culms upward and feeding them to the threshing device 5 is configured. The threshing device 5 is configured by arranging a threshing unit 10, a rocking and sorting unit 11, a first collecting unit 12, a second collecting unit 13 and the like configured as follows.

The threshing unit 10 does not leak from the handling barrel 15 that rotates around the horizontal axis P in the handling chamber 14 for handling and processing, the receiving net 16 disposed below the handling chamber 14, and the receiving net 16. A beater 17 and the like for scraping out the processed material and dropping and supplying the processed material to the swing selection section 11 are provided.

The rocking / sorting unit 11 is arranged from the lower rear side of the threshing unit 10 to the rear side, and sorts a sorting case 18 and a sorting wind for sieving and sorting the processed products while swinging and transferring the processed products to the rear side. It is equipped with Karato 19 to be sent, a belt conveyor 20 for selection which is driven by switching the rotation direction of rice, wheat and soybeans. The sorting case 18 is oscillated back and forth by an eccentric crank mechanism (not shown), and a chaff sheave 21 for rough sorting, a straw rack 22 and the like are provided therein. Further, as shown in FIG. 3, a plurality of straw risers 24 are arranged in parallel on the upper part of the sorting case 18 so as to be capable of swinging back and forth via a pair of swing links 23a, 23b, and front swing The link 23a and the selection case 18 are interlockingly connected by a link mechanism 25, and the selection case 18 and the stray riser 23 are configured to oscillate back and forth in an anti-reverse manner to reduce vibration.

Further, as shown in FIG. 2, the lateral width L1 of the handling chamber 14 is set to be smaller than the lateral width L2 of the rocking / sorting section 11, and the handling chamber 18 is arranged to the left side of the machine body. A part of the control part 4 is configured to enter a right side concave portion of the front part of the threshing device formed by the one-sided arrangement of the chamber 14. Then, the sink plate 26 that receives the leaked material from the receiving net 16 and supplies it to the front part of the rocking sorting part 11 is provided between the front wall part 14a of the handling chamber 14 and the front part of the sorting case 18. Has been installed. The sink plate 26 has its front end pivotally connected to the handling chamber front wall portion 14a so as to be vertically swingable, and has its rear part connected to a pin 27 provided on a side plate of the sorting case 18 through an elongated hole 28. The sink plate 26 is configured to swing up and down around the front end as the sorting case 18 swings back and forth.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configurations of the accompanying drawings by the entry.
