Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a threshing device.

[Problems to be solved by conventional technologies and devices]

In a thresher, especially when threshing a culm damp with rain, morning dew, etc., the threshed product is apt to adhere to the net and become clogged, but in this case, conventionally, the net should be brushed or the like. Not only is it time-consuming to clean artificially,
The cleaning had to be interrupted for an extended period of time.

An object of the present invention is to prevent clogging of the receiving net from occurring easily, and to make it possible to eliminate the clogging easily and quickly.

[Means for solving problems]

In order to achieve the above-mentioned object, the threshing device according to the present invention is provided with a drive rotating body for rotating the receiving net, and reciprocates so that the receiving net reciprocates within a small range along the peripheral surface of the handling cylinder. A drive form switching mechanism is provided for switching the drive form of the drive rotating body between a first drive state in which it is rotated and a second drive state in which the receiving net is rotated so as to rotate in a fixed direction. It is characterized by that.

The operation and effect of this characteristic configuration are as follows.

[Action]

That is, when the drive rotating body is brought into the first drive state by operating the drive form switching mechanism, the receiving net is reciprocally driven in a small range, and the threshing processed material is shaken so as not to easily adhere,
The scraping action of the handling teeth on the adhered matter is performed, and the drive rotating member is moved to the second position by operating the drive mode switching mechanism.
When in the driven state, the receiving net is rotated in a certain direction, which allows the receiving net to bend along the drive rotating body with a small radius to peel off adhering substances, or to move the receiving net from the upper side to the lower side. It can be reversed so that the attached matter can be dropped.

[Effect of device]

Therefore, by being able to reciprocally drive the receiving net in a small range, it becomes possible to make it difficult to cause the adherence of the processed material and to prevent the clogging. If the clogging nevertheless occurs, the receiving net can be moved in a certain direction. The clogging can be cleared easily and quickly just by rotating it to the right, and the number of interruptions of work and efficiency reduction necessary for clearing the clogging can be reduced, and the time taken to clear the clogging can be shortened. From both sides, the efficiency decrease due to clogging is suppressed as much as possible,
It has become possible to improve the efficiency of the entire work.

The receiving net (1) will be described in detail. As shown in FIGS. 2 to 4, the receiving net (1) arranged below the handling barrel (2) is provided with a pair of net-like bodies (1a), ( 1a) and the first threshing treatment product drop hole (15) larger than the threshing treatment product fall hole (14) of the first receiving net portion (1A). Second net part (1B) consisting of a plurality of rod-shaped members (1b) ...
And an endless belt (1) formed on the endless belt is attached to the endless chains (16) and (16).

Then, the endless chains (16), (16) are respectively wound around a drive chain sprocket (17) and a free-running chain sprocket (18) as a drive rotor, and the chain (1

The chain guide rails (21), (21) are slidably provided, respectively, so that the drive net sprocket (17) can be driven to rotate the receiving net (1).

As shown in FIG. 1, a changeover switch (22) for changing over the drive state of the drive chain sprocket (17) is provided, and an electric motor for the drive chain sprocket (17) is changed by changing over the changeover switch (22).
First operation circuit (24) and second operation circuit (25) for driving (23)
Each of them is provided with an electric motor via the first operation circuit (24) by operating the changeover switch (22) to one side.
By driving (23), as shown in FIGS. 5 (a) and 5 (b), the first net part (1A) is reciprocally rotated so as to reciprocate along the handling cylinder (2). 1 drive state and the changeover switch (22)
The other side to drive the electric motor (23) via the second operation circuit (25), and as shown in FIGS. 6 (a) and 6 (b), the first receiving net portion (1A) The second is rotated so that the
The drive chain sprocket (1
A drive mode switching mechanism (26) for switching 7) is configured.

Therefore, by operating the changeover switch (22),
By setting (1) to the first drive state, the grains and straw debris that are about to adhere to or adhere to the first receiving net portion (1A) are peeled off so that the mesh of the receiving net (1) is early. It is possible to suppress clogging, and by operating the changeover switch (22) to put the receiving net (1) in the second drive state, the first receiving net (1A)
When it passes through the chain sprockets (17) and (18), it peels off when it bends, or when the first net-receiving part (1A) is inverted, it falls down by its own weight, etc.
It is designed to be able to remove grains and straw debris attached to A).

In addition, when the receiving net (1) is rotated once, the first receiving part (1A)
Is located at a position facing the sorting section (B), the second receiving section (1B)
Is located at the position facing the handling cylinder (2), and this second
Although the receiving net (1B) can receive the grain culm supplied and can shed grain from the grain culm, it cannot perform threshing treatment, so when setting the net (1) to the second drive state. Although the threshing efficiency decreases, as mentioned above,
By setting the receiving net (1) in the first driving state so as to reciprocate the first receiving net (1A) along the handling cylinder (2), the first receiving net (1A)
Make sure that the mesh is not blocked for a long time,
By reducing the number of times the first receiving net portion (1A) is put into the second drive state, it is possible to avoid the threshing efficiency from decreasing as much as possible.

In addition, (27) shown in FIG. 2 is a brush that scrapes against the first net-receiving part (1A), and the brush is applied to the first net-receiving part (1A) when the receiving net (1) is in the second driving state. It is designed to scrape off the attached grains and straw chips.

[Another embodiment]

As shown in FIG. 8, the receiving net (1) is connected to a pair of chains (1
6), (16) A pair of nets (1
You may comprise only the 1st net-receiving part (1A) which consists of a) and (1a). In this case, when the receiving net (1) is rotated once, if the first receiving part (1A) is located at the position facing the sorting part (B), the part of the receiving net (1) facing the handling cylinder (2) is located. Since there is nothing to accept the grain culm,
If the threshing process cannot be performed and the net (1) is rotated once, the threshing work must be interrupted and the work efficiency will be reduced, but as described above, the net (1) Is set to the first state, the number of times the receiving net (1) is rotated once is reduced, and it is possible to avoid a decrease in work efficiency as much as possible.

In the above-mentioned embodiment, the receiving net (1) is artificially switched between the first driving state and the second driving state. However, it is detected that the mesh of the first receiving net (1) is clogged. When it is detected by the above, the receiving network (1) may be automatically switched from the first driving state to the second driving state. If there is a large amount of grain culm supplied or if there is leakage threshing, grains and straw debris will be generated in the first receiving net (1A).
The receiving net (1) may be set to the first driving state only when it easily adheres to the sheet, and the receiving net (1) may be set to the stopped state in the normal state.
