Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field of Application The present invention relates to a second reduction in a threshing machine equipped with a handling chamber that stores a screw-shaped handling cylinder with a screw-type wound around its surface. It is related to the device.

(b) Conventional technology Conventionally, threshing machines equipped with a handling chamber that stores and mounts this type of screw-type handling cylinder, and threshing machines equipped with a handling cylinder in which inverted ■-shaped handling teeth are installed, have not been used. , for example, JP-A-58-16
As disclosed in Japanese Patent No. 5710, the second grains after threshing were returned to the middle or end of the handling chamber from the start to the end.

Therefore, the conventional method has the disadvantage that the processing action in the handling chamber for the second material to be reduced is short, resulting in insufficient processing action.

(c) Problems to be Solved by the Invention Therefore, the present invention improves the sorting performance by making the processing action in the handling chamber for the second material to be reduced long and providing sufficient processing action. It was created with the aim of eliminating the loss and solving the above-mentioned drawbacks of the conventional method, and also to enable smooth return without clogging when returning the second item to the handling room. It is something.

B) Means for solving the problems The present invention takes the following technical means to achieve the above object. In other words, at the starting end of the handling chamber where the Mekly-type handling cylinder is stored and racked, the second product after threshing-style sorting is returned to a part of the downward rotating part of the handling cylinder for processing. What should I do?

09 Effect Since the present invention has taken the technical means described in the previous section,
The entire amount of grain culms supplied to the starting end of the handling chamber is sent to the terminal end through the screw blades and subjected to threshing action, and the first grain among the grains leaking out from the handling chamber and wind-selected is However, the second item is returned to the starting end of the handling chamber and is subjected to processing action during the long journey to the ending end.

In addition, when the second item is returned to the starting end of the handling chamber, it is returned to the upper part of the handling cylinder that rotates downward, and is taken into the handling chamber by the rotation of the handling cylinder and sent to the terminal side in sequence. .

(f) Examples The present invention as described above will be explained below based on the drawings of examples.

The screw-type threshing machine shown in this section is mounted on a crawler and has a cutting section in the front to form a combine harvester. The culm is chopped and cut with the cutting blade (2), and the cut culm is sent from the scraping auger (3) to the feeder house (4).
) The slurry 4 is transported to the starting end of the handling chamber (6) by the chain conveyor (5) in
- It is sent from the starting end to the ending end by a mold handling cylinder (7) and is subjected to threshing action.

In the process of threshing, the grains and straw waste leak out from the receiving net (8) and fall into the lower swinging sorter (9); ifl) and discharged outside the machine.

The spillage including grains that has fallen onto the oscillating sorter (9) is caused by its oscillating motion and the sorting wind that is blown up by the blower fan (11) and blows through the lower side of the oscillating sorter (9). The first product falls into the 1st gutter (the 2nd product falls into the 2nd gutter 03), and the 1st product (the 1st product with increased thickness is lifted up and stored in the paddy tank 0 → , the second article in the second gutter 03) is returned to the handling chamber (6) by a spiral conveyor cylinder (■) and subjected to processing action.

Next, the main parts of this invention will be described.

06) Huscley - A transverse transfer gutter with a conveyor (16a) installed inside and installed horizontally on the outside upper part of the starting end of the handling chamber (6), the starting end of which communicates with the upper end of the spiral conveyor tube (b)) and jumps out. It is designed to inherit the second item thrown by the feather (1st).

A dumping port 08) is opened next to the handling chamber (6) on the terminal end side of this cross-transfer transfer gutter (16), and the shaft of the scree conveyor (16a) corresponding to this dumping port ((5) is A scraping blade α9) is attached, and the starting edge of this scraping blade 09) is formed into a slope (19a) and a long hole (19b).
It allows you to freely adjust the entrance and exit.

The upper part of the handling chamber (6) is formed by a handling trunk cover (corporate), and the handling trunk cover (incorporated) is particularly designed to extend upward with one side as a fulcrum, as shown in Figures 4 and 5. It is constructed so that it can be opened and closed by rotating it, and the wall surface portion corresponding to the outlet (E) on the terminal side of the transverse transfer gutter α6) of this handling barrel cover (Foundation) has a wall surface that matches this outlet (G). Inlet (21)
A flexible body (b) such as a sponge is pasted around the opening to improve the connection with the outlet (+8).

The above-mentioned receiving port (zl) is an overhanging part (2) that extends the other side of the starting end of the handling cylinder cover (zl) to the side to form a space (zl).
The opening spans the wall of 0a).

Further, the handling cylinder (7) is moved simultaneously in the direction of the arrow (A) by an appropriate drive mechanism (not shown), and the scree conveyor (XSa) in the transverse transfer gutter α6) and the scraping blade (1□ □□
The power extracted from the upper end of the helical conveyor shaft inside the helical conveyor tube 0.5) is transferred to the arrow (b) through Che 7 (Foundation).
It is configured to rotate in the direction of.

As shown in Fig. 5, the spiral conveyor tube (15) has an upper body (5a) that can be attached and detached from a lower body (15b), and an opening/closing lid (2) on the side wall of the handling chamber (6). ) is open so that when the two-part body (15a) is removed, the lower body (15b) communicates directly with the inside of the handling chamber (6) through this window. Also shown in Fig. 3 by imaginary lines -
1 shows a ring-shaped anti-wrapping body.

However, at -, the second object in the second gutter (+8) lifted by the spiral conveyor tube θ5) is thrown out by the jump blade α and transferred to the starting end side of the transverse transfer gutter 06). After being transferred to the terminal end by the screw conveyor (16a), the scraping blade (19) rotating in the direction (b) moves the material from the outlet (e) to the receiving port (21) into the space (transfer). Screw that is taken out and rotates in the direction (a), - type handling cylinder (6
) is taken in and sent through the treatment chamber (6) from the starting end to the ending end while being processed.

In addition, as mentioned above, by removing the upper body (15a) of the spiral conveyor tube (E), the second item can be returned directly into the handling room (6) through the window with the opening/closing lid (3).

(g) Effects of the Invention As explained above, the present invention provides a structure in which, at the starting end of the handling chamber in which the scree-type handling cylinder is stored and racked, the second grain after threshing-style sorting is placed on the upper part of the downward rotating side of the handling cylinder. Since the structure is such that the second material is processed by reducing it, the second material receives a long processing action from the beginning to the end of the handling chamber, and sufficient processing is carried out to improve the sorting performance and reduce the amount of waste to the outside of the machine. There will be no loss.

In addition, since the second material is returned to the upper part of the downward rotation of the handling cylinder, it is better taken into the handling chamber, and there is no clogging, resulting in smooth return.
