Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a threshing sorting device.

[Conventional technology]

In a threshing sorting device, even if the threshing material adheres to the receiving net, as when threshing stem culms moistened by rain or morning dew, it can be easily removed. 2
He proposed the method shown in No. 30669. That is, when the receiving net is attached to a portion of the entire length of the endless cable and the endless cable is rotated, the receiving net moves between the threshing position along the handling drum and the lower part of this position. When the receiving net is rotated and the winding for the endless ropes passes through the location where the ring is installed, it curves along a small radius, which may cause the deposits to peel off, and the receiving net is used for threshing. When the net moves downward from the threshing position, the surface of the receiving net changes direction from the upward direction when it is in the threshing position to the downward direction, so that the deposits fall off. In addition, when the receiving net is in the threshing position, only the endless cables are below the receiving net, so that the threshed material that passes through the receiving net and falls to the sorting section can be smoothly supplied to the sorting section. We have taken this into consideration. In other words, if the receiving net is formed into an endless net so that there is a receiving net section below the threshing position, the threshed material falling from the receiving net section located at the threshing position will fall into the sorting section. The lower part of the net becomes an obstacle to the receiving net, and the threshed material tends to accumulate in the loops of the receiving net.

[Problem that the invention seeks to solve]

In the case of the method proposed earlier, while the receiving net is removing deposits, that is, while the receiving net is rotating, it stops catching the grain culms to be threshed and allows the handling action by the handling cylinder. Since there is no means to catch the grain culms, threshing must be interrupted during the removal work, and there is room for improvement in this respect.

An object of the present invention is to enable smooth supply of the threshed material falling from the receiving net to the sorting section, and to facilitate the removal of deposits attached to the receiving net, and to facilitate the threshing process even when removing the deposits. The point is to make it easy to obtain a structure that can be continued.

[Means for solving problems]

The characteristic configuration of the threshing sorting device according to the present invention is that the entire length of the endless cord-like body is rotatable so that the receiving net can be rotated between a threshing position along the handling drum and a position below the threshing position. A supporting member is attached to a part of the receiving net located at the threshing position in contact with the back side of the receiving net to receive the receiving net, and the grain falling hole is larger than the grain falling hole of the receiving net. so, and,
The receiving net is formed in a lattice shape so as to receive and support the grain culm to be threshed when it is not in the threshing position, and its functions and effects are as follows.

[For production]

Normally, work is done with the receiving net in the threshing position. Then, since the grain falling hole in the support member for the receiving net is larger than that of the receiving net, and because only the endless cords are below the supporting member, the processed material falling from the receiving net can easily pass through the support member and the location where the endless cable is present below the support member and fall into the sorting section.

If the receiving net is contaminated with waste, rotate the receiving net using an endless cable to curve the receiving net with a small radius, or bend the receiving net upward when the surface side of the receiving net is facing the handling barrel. The direction can be changed downward from In this case, the support member faces the handling cylinder in place of the receiving net, and even if grain culms to be threshed are supplied, the handling cylinder receives and supports them so that they can be handled and acted upon.

〔Effect of the invention〕

The ability to rotate the receiving net makes it easier to remove adhering substances, making it easier to prevent and eliminate clogging.

Moreover, due to the size of the grain fall hole of the support member,
The material to be threshed can be smoothly dropped and fed to the sorting section, making threshing work more efficient.

Furthermore, since the supporting member acts to catch the grain culm even when removing the deposits on the receiving net, the grain culm can be continuously supplied and the threshing operation can be reduced. This also made threshing work more efficient.

Moreover, since the members for supporting the net can also be used as the members for supporting the grain culms, the structure can be simplified, which is economically advantageous.

〔Example〕

As shown in Figure 7, the harvested grain culm is supplied to the handling chamber (2) by the threshing feed chain (1), and the handling cylinder (3) rotates.
), the threshed grains are dropped from the receiving net (4), the threshing dust is dropped from the dust outlet (5), and the threshing section straw is carried out from the handling room (2) by the threshing feed chain (1). The threshing section is configured in A sorting device that can be driven and moved freely (
6), a winnow (7) that supplies a sorting wind in the direction of the handling cylinder axis;
Further, a sorting section is provided from below to the rear of the threshing section, and has a rotating fan (8) that sucks sorted dust together with the sorting wind and discharges it to the outside of the machine. A screw conveyor (9) transports the first processed material from the sorting section to the outside of the machine, and a screw conveyor (9) returns the second processed material from the sorting section to the handling room (2) to be reprocessed. 10) is provided at the bottom of the sorting section, thereby forming a threshing and sorting device for a combine harvester.

As shown in FIGS. 2 and 3, the receiving net (4) consists of a pair of endless chains (11) distributed at the front and rear ends of the handling chamber (2). 11) Each of the pair of endless chains (11) and (11) is attached to one of the pair of chain sprockets (12) and (13). 12), it is configured so that it can be rotated along the guide rail (14) forming the upper path and the guide rail (15) forming the lower path, and the pair Endless chain (11) (11) (1
The structure is such that the receiving net (4) can be rotated between the threshing position along the handling drum (3) and a location located below the threshing position by the rotation operation of step 1). . A pair of attachment rods (17) are placed in such a state that the support member (16) for receiving the receiving net (4) in the threshing position is placed so as to contact and act on the back side of the central net (4). , (17) is attached to the fuselage via. The support member (16) is a first
As clearly shown in the figure, a plurality of curved support rods (16a) lined up at set intervals in the direction of the rotation axis of the handling cylinder, and a plurality of curved support rods (16a) lined up at set intervals in the circumferential direction of the handling cylinder. It consists of a linear support rod (16b)...so that the grain fall hole (18) is larger than the grain fall hole (19) of the receiver M4 (4).
In addition, when the catch net (4) is not in the threshing position, the grain culm to be threshed is formed in a lattice shape so as to receive and support the grain culm to be threshed without leaving the handling barrel (3). .

That is, in normal times, as shown in Fig. 5, the receiving net (4) is positioned at the threshing position, and the receiving net (4) is supported to prevent it from deforming or separating from the handling cylinder (3) by more than the set interval. Parts (16

And Uke 111i! If straw waste or threshed grains adhere to the net (4), as shown in Figure 6, rotate the catch net (4) and move the catch net (4) to the chain sprocket (
), (13) by curving it with a small radius, or using a receiving net (
4) change the surface side from upward to downward so that the deposits can be removed by peeling or falling, and also at this time, the support member (16) acts to support the grain culm, so that is supplied so that threshing operations can continue.

The receiving net (4) is made of a resin sheet as shown in FIGS. 3 and 4. Then, by inserting the end of the reinforcing shaft (20) into the connecting hole of the link plate of the endless chain (11) and preventing it from coming out with the pin (21), the bent shaft center of the chain link plate and the receiving net ( 4
) is connected to the endless chain (11) in such a way that the center in the thickness direction is the same as the center in the thickness direction.

[Another example]

A belt or the like may be used instead of the endless chain (11), and these are collectively referred to as the endless cable (11).
