Description

[Detailed Description of the Invention] [Industrial field of application] The present invention has an axial-flow type handling cylinder that handles and treats a processed object while rotating it around an axis in the front-rear direction and extends it to the front and rear of a handling chamber. The present invention relates to an all-culm throw-in type threshing device in which a receiving net is stretched along the lower side of the handling cylinder and a sorting section is arranged below the receiving net.

[Conventional technology]

An example of this type of all culm throwing threshing device is Japanese Patent Laid-Open No. 62-13044.
As disclosed in FIG. 3 of Japanese Unexamined Patent Publication No. 2 (1994), it is general that the leaked substance that has leaked from the receiving net falls directly to any part of the sorting section.

[Problems to be solved by the device]

The axial-flow type handling cylinder is long in the front and back, and many processed materials are handled and processed in the first half to be shredded, so many grains leak from the first half of the net and flow to the front of the sorting section. To fall. On the other hand, the grains that were transferred to the latter half of the net without leaking, or were processed by the latter half of the handling cylinder and shattered, are mostly the latter half of the sorting section that leaked from the latter half of the net. Falls to the section.

However, the grain that leaks from the latter half of the net is mixed with many other grain with branches and straw debris and falls into the sorting section.
Even in the sorting section, the sorting action can be performed only for a short period of time, so that many grains are discharged to the outside of the machine together with straw waste without being collected.

The purpose of the present invention is to prevent the grains leaked from the latter half of the receiving net and the grains with branches from being discharged to the outside of the machine by installing a new mechanism in the processing distribution route from the handling cylinder. To increase the grain recovery rate.

[Means for Solving the Problems]

A characteristic configuration according to the present invention is that a longitudinally-belt-type protruding belt for receiving a processing object leaking from the receiving net and sending it forward is wound around the lower half of the receiving net in the front-rear direction. The point is that a sorting net that moves back and forth in a short period is provided along the lower side of the lower rear conveyance path of the belt with protrusions, and the function and effect thereof are as follows.

[Action]

That is, the processed products such as the grains and the grains with branches and straw scraps leaking from the latter half of the receiving net are received on the upper path side of the belt with the protrusions and returned to the front once, and the process returned to the front. The object is sent backward on the lower path (return) side of the belt with protrusions. At the time of feeding through this lower path, frictional “fir” action with the sorting net causes the grain to be granulated and leaks to the sorting section.

Moreover, since the sorting net moves back and forth in a short cycle,
Since the sorted net-like processed product comes into contact with one projection many times, the fir effect of the processed product from the projection can be increased as a whole.

[Effect of device]

As a result, it is possible to drop the processed material that has undergone singulation processing into the latter half of the sorting unit as well as the first half, and increase the efficiency in the sorting unit and reduce the grain scattering rate. Came to. Moreover, by moving the sorting net back and forth,
It is possible to increase the singulation rate as compared with the case of fixing.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

The all culm throwing type threshing device (1) will be described. While rotating around the longitudinal axis (P), the axial-flow type handling cylinder (6) that handles and processes the processed material and sends it back is mounted on the front and rear of the handling room (5).
A catching net (9) is stretched below the handling cylinder (6), and a swing selecting part (A) is arranged below the catching net (9). A threshing device (1) is provided by providing a first-item collection unit (18) for collecting the first-item and a second-item collection unit (19) for collecting the second-item.
Is configured.

The handling cylinder (6) has several pairs of front handling teeth (2a) arranged in three rows in a spiral shape at the front end of the outer peripheral surface of the body formed in the shape of a cage elongated in the axial direction to form a handling chamber ( In addition to causing the grain culms to be thrown into 5) to be drawn further into the handling chamber (5), the handling teeth (2b) on the rear side of transportation are planted, and the rear handling teeth (2b) are approximately surrounded by their longitudinal direction. The front handle (2a) is installed so that its longitudinal direction is inclined with respect to the circumferential direction with respect to the installation so that the retracting force at the front handle (2a) is increased. ing. The handle teeth (2a), (2b) are detachably bolted to the handle body (6) in consideration of maintainability. Therefore, while the cutting grain culm pulled in by the front handle tooth (2a) is treated with the rear handle tooth (2b),
Finally, the non-leakage material remaining on the net is discharged from the dust inlet (3) at the rear end.

Below the latter half of the receiving net (9), a plate-like protrusion (10
A longitudinally rotatable projection belt (10) provided at equal intervals in the circumferential direction is wound in the front-rear direction, and a sorting net (11) is stretched along the lower surface of the projection belt (10). . Then, the spilled material that has leaked from the latter half of the receiving net (9) is received and placed and conveyed forward, and supplied between the lower surface of the belt with protrusions (10) and the sorting net (11). I am doing it. The leaked material supplied here is a protrusion
(10a) and the sorting net (11) are subjected to friction treatment to be made into single grains, and the paddy and the paddy with branches leak through the sorting net (11) and the sorting part (A)
While falling to, the remaining scraps are transferred to the rear and discharged outside the machine. The sorting net (11) is replaceable, and is configured to be adjustable in parallel movement up and down so that the strength of friction processing can be changed.

The oscillating sorting section (A) is the first rice that is a single grain of the leaked material that has leaked from the receiving net (9), the second one that contains a lot of branched rice, and straw dust. The upper and lower chaff sheaves (12), (13) and the Glen sheave (14) are arranged between a pair of swing sorting plates so that they can swing together and the front of them. It is configured with a Kara-mino (15) that sends the sorting wind below. A gren pan (16) is connected to the front part of the upper chaff sheave (12), and a straw rack (17) is connected to the rear part of the gren sheave (14).

Next, the integral swing structure of the swing selection section (A) will be described. The frame (4) integrally supporting the lower chaff sheave (13), the Glensiegue (14), and the straw rack (17) is driven by the rear crank mechanism (7), and the frame (4) is rolled at the front end. (8) I support it. On the other hand, the upper chaff sheave (12) and the Glen pan (1
An upper frame supporting 6) and 6) is connected to the swing frame (4) so that both swing together. And
The sorting net (11) is attached to the swing frame (4) and swings integrally with the swing arm (4). Therefore, the friction effect between the screening net (11) and the processed material can be further enhanced.

[Another embodiment]

The sorting net (11) is attached to the swing frame (4) as a structure for moving the sorting net (11) back and forth in a short cycle. As shown in Fig. 2, the sorting net (11) is fixed so that it can swing back and forth. Frame (2
0), (20), the pulley (21) for driving the crank mechanism (7) and the fixed frame (20) are linked by the link mechanism (22) to slide the sorting net (11). The configuration may be adopted.

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 present invention is not limited to the structure of the accompanying drawings by the entry.
