Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention comprises an axial-flow type handling cylinder that handles and processes the workpiece while rotating around its axis in the front-rear direction and sends it to the rear, extending from the front and back of the handling chamber. The present invention relates to a whole-culm-throwing type threshing device which is mounted on a shaft and has a receiving net stretched along the lower side of the handling drum.

[Conventional technology]

Such a whole culm input type threshing device is disclosed in Japanese Patent Application Laid-Open No. 60-24
As disclosed in Japanese Patent No. 4223, screw teeth were provided over the entire outer circumference of the handling cylinder 1, and the screw teeth were configured to frictionally stir the material to be processed and send it to the rear while being processed. .

[Problem that the invention seeks to solve]

However, since the screw teeth are a series of formed products, they have a high feeding capacity and are excellent for high-load work, but on the other hand, they cannot give an effective blow to the processed material, making them difficult to shed. There was a tendency for leftovers to occur during crop processing.

The present invention was devised by paying attention to the above-mentioned circumstances, and its purpose is to sufficiently increase the ability of the handling cylinder to feed and handle the material to be processed, and to enable threshing with high recovery efficiency. It is in.

[Means for solving problems]

The characteristic configuration of the present invention is that a scraping screw is provided on the front outer periphery of the handling cylinder, and small screw teeth with a rearward feeding slope are provided in a spiral shape behind this screw. A handling tooth without a rearward feeding slope is provided at the rear of the handle, and its functions and effects are as follows.

[For production]

In other words, the material to be processed entering the handling chamber is smoothly guided backwards by a scraping screw installed on the front outer periphery of the handling barrel, and then is given a weak blow by small screw teeth installed in a spiral shape. The remaining processed material is sent to the rear while the single grained paddy is allowed to leak through the receiving net.Then, the processed material that has been sent is processed so that it does not have a rearward feeding slope. The paddy is thoroughly handled and processed by giving a strong blow with its teeth, and the single grains of paddy etc. leak through the receiving net.

[Effects of the Invention] According to the present invention, by providing a scraping screw on the outer periphery of the front part of the handling cylinder, it has become possible to guide the processed material into the handling chamber without delay. In addition, by providing small screw teeth at the rear of the screw, the material to be processed can be subjected to preliminary handling, and later handling can be carried out effectively, reducing dust loss.

Therefore, not only the ability to feed the processed material but also the ability to handle it has been sufficiently increased, making it possible to perform threshing with high recovery efficiency.

4A) and (4B) are arranged in upper and lower two stages. The rotating barrel (4A).

(4B) has a drum shape with protrusions on the outer periphery, and rotates counterclockwise in the figure around the left and right horizontal axes.

The threshing section (B) is a handling chamber (5) formed in the upper part of the machine.
The handling cylinder (6) is mounted on a shaft over the front and rear of the handling cylinder (6).
) is constructed by disposing a receiving line (9) on the lower side. The handling barrel (6) is of an axial flow type that rotates around a longitudinal axis (6a) installed in the longitudinal direction of the fuselage. As a result, the cut husk put into the handling room (5) from the handling room entrance (5a) is handled and sent to the upper rear part of the machine body.

The sorting section (C) separates the leakage material from the receiving net (9) into first grains, which are single-grained paddy, second grains, which contain a large amount of paddy with branches, and straw waste. There is a chaff sieve (12) in two stages, upper and lower, spanning between a pair of swinging sorting plates.
(13) and grain sheave (14) are provided so that they can swing together, and a winnow (15) is provided to send a sorting air downward in front of them. In the front part of the upper chaff sieve (12), there is a grain pan (16),
In addition, there is a straw at the rear of the lower chaff sheave (13).
Racks (17) are arranged in series.

The collecting section (D) is arranged below the sorting section (C), and is connected to the first article collecting section (18) which collects the first article that has fallen from the sorting section (C) and transports it to the side. ), and a second product collection section (19) that collects the second product and transports it to the side.
) is connected, and the transported first grain is sent to the grain tank (T). Further, a thrower (21) is connected to the conveyance end of the second article collecting section (19), and the second article that has been conveyed is sent to the processing chamber (22).

Next, the handling cylinder (6) will be explained in detail.

As shown in FIG. 1, the handling cylinder (6) has a pair of front and rear disc-shaped mounting bases (7) that rotate around the longitudinal axis (P).
A plurality of rectangular rod-shaped tooth stands (8) are installed at regular intervals in the circumferential direction and fixed with bolts, and a cylinder (1
0) is fitted onto the outside to form the main body portion. A scraping screw (23) is provided on the outer periphery of this cylindrical body (10), and a handling tooth table (
8) A small screw tooth (24), a handling tooth (25), and a blade member (26) are provided in this order on the top to constitute a handling tooth section.

To be more specific, the screw (23) is for smoothly guiding the processed material introduced into the handling chamber (5) to the rear, and prevents clogging near the entrance (5a) of the handling chamber.

The small screw teeth (24) are plate-shaped with a rearward feeding slope, and are spirally provided astride the two handling tooth stands (8). Then, the processed material introduced by the screw (23) is treated by giving a weak blow, and the single grained paddy is received! ! ! As it leaks from (9), the remaining processed material is released and sent to the rear.

The handling tooth (25) is a protrusion that does not have a backward feeding slope, and handles the workpiece sent by the small screw tooth (24) in earnest by applying a strong blow and cutting action to the workpiece. The processed and single-grained paddy leaks from the receiver W4 (9). The remaining processed material is gradually sent rearward along a guide plate (27) provided above the handling chamber (5).

The blade member (26) is a band-shaped member having rectangular wave-like unevenness, and is provided along each of the handling tooth stands (8). Only a blow is applied to the processed material sent from the handling tooth (25) side to make it into single grains, thereby promoting leakage from the paddy receiver 11 (9). On the other hand, the remaining processed material is gradually sent rearward along the guide plate (27) and is finally discharged out of the machine from the dust outlet (5b).

As explained above, the whole culm loading type combine uses the screw (23), small screw teeth (24), handling teeth (25), and blade members (26) to create a load inside the handling chamber (5). This improves the handling and feeding capacity for processed materials.
