A threshing device has been proposed in which a wind selection chamber is formed below the rear blower fan and the dust exhaust cylinder toward the front side.

(Issuance i+ that Jg+ tries to solve! l11) 111
The threshing device of the first application has a problem in that the sorting in the distant area (front side) is not sufficient because the wind blown by the rear blower fan becomes weaker as the distance increases.

Therefore, in this application, straw can be evenly sorted over the entire width of the wind sorting room.

(-f step to solve the problem) Therefore, 9. The light is a horizontal shaft handle 11 with multi-O handle teeth 3 erected on the A side. A processing IF on the horizontal axis is provided with a processing chamber 2 for processing i4, and a large number of processing teeth 19 are erected on the inner surface on the rear side of the processing chamber 2.

The grains from the processing chamber 18 fall almost downward due to their own weight, but the grain threshing in the No. 1 chamber 2 is handled with IH4) (Rotating 1:
At section J), the falling objects in the processing chamber are biased towards the φ side and fall into the processing chamber 18, and the falling objects in the processing chamber merge with the inside of the processing chamber 18 at the lower blade of the processing chamber 18. This is blown to the front side by the rear ventilation fan 35 to be diffused, thereby being evenly distributed in the width direction in the wind translation chamber 8, and uniformly swept across the entire width of the wind selection chamber 8, so that it can be efficiently processed. It is something to do.

Reference numeral 36 denotes a suction fan installed on the ;11j side of the VL selection room 8, which works together with the rear blower fan 35 to suction and remove the air to evenly distribute the air in the J room B. Also, remove any light dust or straw from the handling room and processing room by suction.

Reference numeral 37 denotes a front plate, and 38 denotes an inclined guide plate provided below the processing chamber 18, which guides fallen objects that have fallen from the processing net η of the processing chamber 18 to the rear blower fan 35. 39 is 2 incense con-

(effect) Next, we will discuss the effect.

With the field in front of the field, the grain culms are separated into grains with the body, the divided grain culms are pulled up with a pulling device, the roots are cut by 9j with a cutting blade, and the grain culms are transferred to the grain culm feeding device 6 by a conveying device. After taking over, the grain culm tips are fed into the handling chamber 2 by the culm supply device 6.

While the culms are being transferred by the shell culm supply device 6, they are threshed and handled by the rotating handle +144 in the handling room 2, and the straw waste and grains are threshed from the net 7 in the M selection room 8 below. fail.

In addition, the discharge side of the handling chamber 2 is connected to the handling chamber 2.
1 dust chamber 24 is excised +5Q, and there is t# in the dust evacuation chamber 24.
Since the dust exhaust 11 to the right of i & J 25 is mounted on a shaft, it is handled among the grains removed in the handling room 2, and the grains collected on the discharge side from v47 are handled in the JJ dust room 24 sent to and processed.

Handling of the handling room 2 147. Out of the threshed grains that fall into the wind selection chamber 8 of the talker from the mesh in the rack room 24, the grains are oscillated (the grains are sent to the first straw rack 10 by the moving rack 9, and The first product is transferred from the first stroke rack 10 to the sorting net 14 and taken out to the first condenser 715.
The second item is taken out to the 2# conveyor 16, and light dust etc. are blown away by the selection air of the supply side blower fan 12 and sucked out of the machine by the discharge side cross-flow suction fan 17.

The second item that fell into the No. 2 conveyor 16 flows into the No. 2 thrower river from the alligator end of the No. 22 conveyor 16 [1, -1- rises to the inclined guide plate 381. will be returned to.

In this case, the falling objects from the processing chamber 18 fall almost downward due to their own hair, and the grain threshing in the handling chamber 2 is biased toward the processing chamber IN 4) (the falling objects in the processing chamber on the rear side due to the rotating relationship). The rice is washed down.

Since one suction fan 35 is installed in the front side of the air filter, together with the rear blower fan, the suction fan 35 works together to suction and remove debris, to evenly distribute debris in the air selection chamber 8, and to remove debris from the handling room and the processing chamber. Light dust and moss among things? Remove by suction.

(Effect) The specification and drawings of Japanese Patent Application No. 1.67400 filed by the same applicant, which corresponds to the priority of the present application, show the handling of a horizontal shaft with a large number of handling teeth erected on the six circumferential surfaces. A processing chamber is provided in which the processing cylinder is installed, and a processing chamber is provided at the rear side of the processing chamber, which has a horizontal processing cylinder with a large number of processing teeth on the circumferential surface.

However, the above-mentioned prior application was removed:! The problem with this device is that the wind blown by the rear blower fan becomes weaker as it moves farther away, so that it is not able to sort out the far side (front side) sufficiently.
