Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing device in which a processing chamber is juxtaposed closely to a handling chamber.

Conventionally, the above-mentioned threshing device was constructed as shown in FIG.
Form a gap partial view between the processing chamber (3) and the handling chamber (3), and extend the receiving net (6) of the handling chamber (3) to the point where it faces the gap partial view in the direction of rotation of the handling cylinder (2). By extending the net, the area of the receiving net (6) is increased, its filtration capacity is increased, and the threshing capacity of the handling room (3) is the same as above. There were other problems, such as easy clogging in the figure, and the formation of the gap (A15e) increased the width of the fuselage, resulting in an increase in the size of the fuselage.

The purpose of the present invention is to: In view of the conventional situation, by effectively utilizing the processing chamber and making simple improvements, it is possible to make the horizontal 13 dimensions of the machine body as compact as possible, while at the same time maintaining the The purpose is to expand the area so that the threshing capacity of the handling room can be increased once, and to prevent clogging of grains, etc., and to perform the threshing process smoothly.

A characteristic configuration of the present invention is that in the above-mentioned general removal equipment, the receiving net in the handling chamber is arranged so that a part thereof in the direction of rotation of the handling cylinder faces the processing chamber.・In other words, the receiving net in the handling room is extended to a point where it directly faces the treatment plan in the direction of rotation of the handling cylinder, and the grains, etc. that have passed through the extended receiving net portion are transferred to the next process via the □ processing room. Since the system is for transporting grains, the conventional gap between the processing room and the handling room can be omitted to reduce the width of the machine, while increasing the offshore area of the receiving net and making it easier to thresh in the handling room. Processing capacity can be improved, and since grains, etc. do not have to pass through narrow thread paths such as gaps, the occurrence of clogging is reduced, making it possible to improve the threshing process f! Moreover, since it is an extremely simple improvement that simply places the receiving net directly in front of the processing chamber, it does not complicate the membrane removal processing structure:
In order to be able to provide a threshing device that is compact, has excellent membrane removal performance, and is advantageous in terms of economy and production, we will explain embodiments of the present invention in detail based on illustrative drawings. Describe.

As shown in Figure wJ1 and Figure 2, the feed chain (
A handling chamber (3) is equipped with a front-backward facing handling cylinder (21) that performs rotary threshing on grain culms that are held and conveyed in a sideways position by a
), and processing chambers (5) containing longitudinal processing cylinders (4) that act to re-thresh the second grain, which will be described later, are installed side by side in the lateral direction of the machine, processing type 1417jTh, etc. Initial screening receiving net 161 stretched over the frontage of section F,
The demembrane-treated material that is downgraded through the
The sorting section (10) that performs ratio 1 sorting accompanied by rearward transport by sorting +91 K is located in the compartment (3).

(5) are provided below, and each transverse feed-out screw (lla) and (12a) separately collects the first and second items sorted in the sorting section (10).
The first article collection part 圓 and the second article collection part tta equipped with
) to the processing chamber i6), and a smear reduction device u3 that supplies vc, and a dust exhaust fan u! that discharges dust such as straw waste after the sorting process from the dust exhaust port u to the machine body. 9 etc. are provided to constitute a threshing device.

As shown in Figures 2 and 8, the front handling room (3) consists of a handling room supported on the upper side of the aircraft between the handling room (3) and the processing room (6). The longitudinal axis Uη for the intermediate pulley ae support of the trunk belt transmission system is also used, and its axis center (Q)
-kF to form the handling room (3)! The As cover (8 holes), the front and rear side plates (8b), (8c), and the clamping rail uI for the feed chain (1) that are integrally connected to them are integrated with the handling cylinder (2) [kF oscillation]. It is configured so that it can be opened and closed dynamically, and can be used to clean the receiving net (6) in the handling room (2) and to operate the sorting unit (lO) with the receiving net (6) removed.
The structure is such that cleaning, inspection, etc. can be easily performed.

Furthermore, when the processing cylinder (4) and the handling cylinder (2) are arranged in parallel,
Place the handling cylinder (2) so that their lower ends are approximately on the same level.
The rotation axis (4 m) of the processing cylinder (4), which has a smaller diameter than K, is placed at a lower position than the rotation axis (2 m) of the handling cylinder (2).
In addition to equalizing the distances from the handling room (3) and the processing room (6) to the number of selected parts of the detached dangerous materials that are supplied dropwise, the rotation directions of these barrels (21, +4) are shown in Fig. 2. The handling cylinder (2) is rotated clockwise and the processing cylinder (4) is rotated counterclockwise, so that the cylinder cylinders 121 and 121 rotate in opposite directions.
+4) By using the centrifugal action to uniformly drop and supply the defilmed material to the number of screening parts in the direction of the lateral force of the machine,
The number of sorted vehicles for sorted copies is flttied to be the same as above.

To explain in more detail the tension structure of the receiving nets 161 and 171, a cross section along the outer circumferential shape of the handling cylinder (2) and the processing cylinder (4) is installed at the lower opening of the handling chamber (3) and the processing chamber (5), respectively. Of each receiving net 161 (7) stretched in an arc shape, the receiving net on the handling chamber (3) side (61'if: processing chamber tel and handling chamber (3) in the rotation direction of the handling cylinder (2) It is extended to the partition wall of the processing chamber (6) so as to directly face the processing chamber (6), and a part of the threshed material from the t& ), the filtration area of the receiving net (6) in the handling room (3) can be increased and the removal capacity of the handling room (3) can be increased without increasing the size of the machine. It is configured to be the same.

In addition, out of the receiving net (6) of the handling room (3), directly to the processing room (5),
Opening shape of directly facing part (6a) and handling room (3)
Various configuration changes can be made to the F section side receiving screen (6) portion, the opening 1111 ratio between the processing chamber (6) side receiving screen (7), etc.

The present invention is directed to AI type de-l112 devices, such as those mounted on combine harvesters, etc., and those of stationary type.
