Abstract

PURPOSE:To eliminate round movement of material to be threshed and to reduce the fourth loss by a handling barrel in a handling chamber in a plural barrel type thresher of equipping the handling chamber and a treating chamber side by side by making open space leading to the handling chamber above the part corresponding to a dust throwing outlet of the treating chamber. CONSTITUTION:Rice straw waste, cut ear, etc., among materials threshed and treated in a handling chamber 2 internally supporting a handling barrel 1 in a shaft are sent from a dust throwing outlet 5 to a treating chamber 6 and treated between the treating chamber and a treating net 12 while being transported toward the shaft by a treating chamber 7. Then the isolated grain granules, finely divided rice straw waste, etc., downwardly dropped from the treating net 12 onto an oscillating selection shelf 13, and the treated materials of waste dust such as large rice straw waste not dropping from the treating net 12 are sent to the edge side of the treating chamber 6 and thrown out from a dust discharging outlet 14 onto the downward oscillating selection shelf 13. In the operation, the treated materials not delivered from the dust throwing outlet 5 of the handling chamber 2 to the treating chamber 6 are brought to open space 11 and temporarily collected so that round movement of material by the handling barrel 1 in the handling chamber 2 is eliminated.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a handling chamber in which a handling cylinder is mounted on an internal shaft, and a processing II in which the handling cylinder is parallel to the handling cylinder. This invention relates to a multi-barrel type threshing processing device in which a processing chamber and a processing chamber in which an internal shaft is installed are arranged side by side.

[Prior art]

Conventionally, a processing chamber has been provided that extends from a part corresponding to a dust inlet opened at the end of the processing chamber to the rear of the processing chamber and has a processing cylinder mounted on an internal axis, to remove straw waste and ear fragments generated within the processing chamber. There is already known a system in which the processed materials are received into the processing chamber through the dust inlet and processed in the processing cylinder, and the processed materials are discharged onto the swinging sorting shelf below through the dust exhaust port opened at the terminal end of the processing chamber. ing.

In this kind of structure, as shown in Fig. 7, the upper part of the processing chamber corresponding to the handling chamber dust inlet is connected to the cover C covering the upper part of the processing chamber and the rotation locus of the handling teeth of the handling chamber. It was separated from the guide plate G provided approximately along the guide plate G.

[Problem to be solved by the invention]

In such a conventional structure, the processed material that was not carried over into the processing chamber from the dust inlet of the handling chamber is rotated in the rotational direction of the handling drum and placed on the waste straw, and the grains are stuck in the waste straw. There was a problem in that it was ejected directly from the aircraft, causing a large number 4 loss.

[Means to solve the problem]

The present invention aims to solve these problems and takes the following technical measures.

That is, the technical means according to the present invention is to provide a dust inlet 5 with an opening at the end side of the handling chamber 2 in which the handling cylinder is mounted on an internal shaft,
A processing chamber 6 is provided which extends to the rear of the handling chamber 2 from a portion corresponding to the dust feeding port 5 and on which the processing cylinder 7 is mounted on the internal shaft, and above the portion of the processing chamber 6 corresponding to the dust feeding port 5. This is characterized in that the upper part of the processing chamber is opened to form an open space 11 communicating with the processing chamber 2.

[Effect]

Among the threshed grains that have been threshed in the handling chamber 2, straw waste, ear fragments, etc. enter the processing chamber 6 through the dust inlet 5, and are transferred between the processing net 12 and the processing cylinder 7 while being transported in the axial direction. processed,
Then, the single grains and the finely divided straw waste leak from the processing w412 to the lower swinging sorting shelf 13'',
This process II! ! For waste disposal materials such as large straw waste that cannot be completely leaked through 112.

From the dust exhaust loe 4 to the end of the processing chamber, there is a downward swing sorting process [
13-18 was thrown out.

Processed materials that have not been carried over from the dust inlet 5 of the handling room 2 into the processing room 6 will be brought into the upper open space 1 and temporarily pooled, and will not be carried by the handling cylinder in the handling room. The sameness disappears.

〔Effect of the invention〕

In short, according to the present invention, the above-mentioned problems can be solved, and in particular, the rotation of the handling cylinder in the handling room is eliminated, and the reduction of No. 4 loss can be greatly reduced. be.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a handling cylinder, and 2 designates a handling chamber in which the handling cylinder 2 is mounted on an internal shaft.The upper part is surrounded by a handling cylinder cover 3, and the lower part is surrounded by a receiving net 4. A dust inlet 5 is opened at the terminal end of the handling chamber 2.

A processing chamber 6 is provided in a region extending from a region corresponding to the dust inlet 5 to the rear of the handling chamber 2 . A processing cylinder 7 is mounted on a shaft within the processing chamber 6 . The processing chamber 6 is configured to straddle the inside and outside of the horizontal side plate 9 of the processing chamber 2, and is surrounded by an outer cover 10 and an inner processing net 12. At the terminal end of the processing chamber 6, the waste to be treated is thrown onto the lower linear motion sorting shelf 13,
A dust exhaust port 14 is opened. An open space 11 is provided above the part of the processing chamber 6 corresponding to the dust transfer chamber 5 with the upper part of the processing chamber open and communicating with the handling chamber 2 side.

The processing cylinder 7 has a large number of solid processing teeth 7a on its outer circumferential surface having a lead angle for moving the processed material backward, and a blade plate parallel to the processing cylinder axis 15 direction is provided at a portion corresponding to the dust exhaust port 14. 7b is provided at the tip of the treated tooth 7a.

The starting end of the processing cylinder 7 is axially mounted on the front plate 16 of the processing chamber 6, while the terminal end is supported via a bearing member F, which is smaller in outer diameter than the processing cylinder 7. is fixed to the side plate 9 with bolts.

The treatment chamber 2 has the treatment II! A U-shaped frame member 20 for fixing the processing net 112 is integrally fixed, and the net frame 12a on one end side of the processing net 12 is fitted and supported by this U-shaped member 20. It looks like this. The mesh frame 12b at the other end of the processed work 2 is fixed to the side plate 9 via bolts 21.
