Description

[Detailed description of the invention] The present invention has a grain separation effect by making the material to be handled pass through the handling section of the handling cylinder and concave two or more times while rotating and flowing the outer periphery of the handling cylinder. and a threshing device designed to improve threshing performance including grain leakage through a concave,
Specifically, the discharge port that opens at the back of the handling chamber that houses the rotating handling cylinder and has a concave at the bottom.
For the grain receiving port that opens at the front of the handling room,
The present invention relates to a plate-shaped guide provided above the handling cylinder, which is provided so as to be offset laterally in the direction of the rotational axis of the handling cylinder, and presses and guides the material to be handled toward the discharge port.

In such a threshing device, it is necessary to use guide tools to accurately press and guide the material to be processed toward the discharge port.However, on the other hand, the guide tools allow a large amount of material to be processed to be pushed near the side wall of the handling chamber. It is preferable not to have the driver guide the user until the end. In other words, if the guide tool's pressure-guiding action toward the discharge port becomes insufficient, the material to be processed cannot be properly supplied to the handling cylinder in the portion corresponding to the discharge port, and the inside of the handling chamber becomes ineffective. This may lead to problems such as clogging of the grain culm, so for example, the guide tool is installed at a steep slope that greatly intersects the circumferential direction of the handling trunk, but on the other hand,
If the guide tool is installed at a steep slope in this way, an unnecessarily large amount of the material to be handled will be guided near the side wall of the handling chamber, and a large amount of the material to be handled will be unevenly distributed at the end of the handling cylinder. Due to these points, there is a risk of unhandled waste, and it is not possible to properly supply the processed material to the handling drum part corresponding to the discharge port using only the guide tool, so improvements are desired. It was hot.

An object of the present invention is to suppress uneven distribution of the processed material near the side walls of the treatment chamber, while allowing the processed material to flow appropriately toward the discharge port side through simple modification.

The characteristic configuration of the threshing device according to the present invention is such that an auxiliary guide plate is placed above the handling barrel to receive the processed material that is pressed and guided by the plate-shaped guide so as to move it away from the side wall of the handling chamber. And, it is located near the lateral side wall of the handling room.

Next, the effects of the feature configuration of the present invention will be described.

That is, the auxiliary guide device receives the material to be processed, which is pressure-guided by the plate-shaped guide device, so as to move it away from the side wall of the handling chamber,
It is designed to prevent a large amount of the processed material flowing into the handling barrel portion corresponding to the discharge port from being unevenly distributed near the lateral side wall of the handling chamber.

Therefore, even if the material to be handled is properly received and guided toward the discharge port by a plate-shaped guide, the material to be handled will not be able to reach the entire part of the handling barrel corresponding to the discharge port. Appropriate handling can be performed while dispersing the particles, and the handling performance can be effectively improved by a simple modification by providing an auxiliary guide.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Figure 1, there is a reel 1 that scrapes the planted grain culms toward the rear of the machine, a cutting blade 2 that reaps the raked grain culms, and a cutting blade 2 that receives the harvested grain culms and collects them toward the center in the width direction of the machine.

The processing cylinder is provided so as to be offset on both lateral sides in the direction of the rotation axis
A plate-shaped guide 13 for pressure dispersion and guidance toward the first side is provided above the handling drum 9 in an inclined position intersecting the circumferential direction of the handling drum, and further, the processed material after the threshing process is discharged to the sorting section 14. A pair of beaters 15 for
15 is provided in a state facing each of the two discharge ports 11, 11, and the material to be treated, which is supplied from the grain culm receiving port 12, is swirled around the outer periphery of the handling drum 9 and flows through the handling drum 9. The threshing processing section between the concave 10 and the concave 10 is passed through twice or more, so that the threshing processing can be performed with less unhandled grain.

The sorting section 14 is configured with a rocking-driven rack plate 16 for transporting the processed material falling through the concave 10 to the rear, and a rack plate 16 for transporting the processed material discharged from the beater 15 to the rear. An auxiliary oscillating sorting plate 18 with a stroke rack is provided, which sorts grains, branch straw with grains, etc. while conveying them to the dust outlet 17, and drops them downward, while conveying and discharging the waste straw to the dust outlet 17. The processed materials supplied from the rack plate 16 and the auxiliary swinging sorting board 18 are sorted by the cooperation of the sorting wind from the winnowing machine 19 and the main swinging sorting board 20, and the grains are placed in the first slot 21 and , the second materials are collected into the second port 22, and dust such as straw waste is sent out to the dust exhaust port 17 and discharged. However, C in the figure is a beater curtain that receives and drops the discharged material from the beater 15 onto the auxiliary oscillating sorting plate 18.

Further, a device 23 for lifting and transporting the grains collected at the first port 21 into the tank 7 is provided so as to sequentially collect the grains after the threshing process. A device 24 is provided for transporting the second grains collected into the handling room A so as to return them to the handling room A, so that they can be threshed again.

As shown in FIGS. 2 to 4, an auxiliary guide plate 25 is provided, which receives the processed material that is pressed and guided by the plate-shaped guide 13 so as to move it away from the side wall a of the handling chamber. Above the handling barrel 9 and near the horizontal side wall a of the handling room, it is pivotally supported around a vertical shaft 26, and an insertion hole for a bolt 27 for fixing the swinging position of the auxiliary guide plate 25 is provided. 28, the vertical axis 26
