Description

[Detailed Description of the Invention] The present invention relates to an improvement in a waste straw processing device for bundling and discharging waste straw after threshing into predetermined amounts.

In general, the waste straw conveying means in this type of waste straw processing apparatus includes: (1) The waste straw after threshing is forcibly transferred in the horizontal direction to the bundling device.

◎ After threshing, the waste straw is dropped vertically and fed into the binding device.

O After the threshing process, the waste straw is sent to the binding device by sliding it down along the inclined path facing diagonally downward.

There are three modes, and each of them has its own characteristics in terms of conveyance function. However, when trying to align the stock of waste straw among these conveyance means, in the method (ii) above, Because it grips the straw from above and below and conveys it horizontally, there is a large difference in supporting pressure due to changes in the volume of the waste straw, and the stock alignment plate pushes the stock end against the clamping pressure. There is a drawback that it is difficult to fully demonstrate the function, and in addition, with the method ◎, even if the stock end of the waste straw comes into contact with the stock alignment plate in the natural falling path, the waste straw culm Since there is nothing to restrict mutual movement of the waste straw groups in this direction, the entire waste straw group simply moves to the tip side, making it difficult to achieve sufficient stock alignment.

When the above-mentioned method ◎ is adopted, the waste straw group slides down the inclined path and becomes separated to some extent in the conveying direction, and there is also slight sliding resistance against the waste straw group even in the direction of the waste straw culm. Although the function of stock alignment using the stock alignment plate is very good, even with this method, if the length of the protruding length on the stock side of the waste straw that slides down the slope path changes, the removal of straw stock There is a drawback that, as the contact resistance between the base end and the stock alignment plate changes, the tip side of the waste straw greatly advances, making it difficult to properly bundle the waste straw bundle.

In particular, when the handling depth is adjusted to change the protrusion length on the stock base side, the contact resistance changes even more, so the position of the stock base alignment plate itself must also be changed. Unless the amount of change in the position of the stock alignment plate and the amount of change in the protruding length of the waste straw on the stock head side match well, the change in contact resistance cannot be reduced, and in reality, the change in contact resistance cannot be reduced. It was extremely difficult to control.

The technical problem of the present invention is to adopt a type of conveying means that slides down the waste straw diagonally downward, and to provide a stock leveling plate on the inclined path so that the stock height of the waste straw can be properly aligned. To reduce the degree of change in the sliding posture of the waste straw, and to feed the waste straw into the convergence space of a binding device with less disturbance of the posture.

The technical means of this invention taken to solve the above problems are as follows:
A binding device is disposed behind the threshing device, and the waste straw discharged from the threshing device in a horizontal position is guided diagonally downward by a conveyance cover when viewed from the side, and is conveyed to the convergence space of the binding device. In this waste straw processing device, a stock alignment plate is provided between the threshing device and the bundling device, and the stock alignment plate has an inclined posture and is positioned closer to the terminal end inward of the machine in plan view. The structure is such that the position of the waste straw can be freely changed and adjusted in the culm length direction, and furthermore, a locking conveyance device is provided on the upper part of the conveyance cover to forcibly convey the waste straw in predetermined amounts, and the locking device is connected to the stock alignment plate. This is because the working part with the conveying device is overlapped in the direction of conveying the waste straw.

The effects produced by taking the above technical measures are as follows.

■ In other words, the straw that slides down on the conveyor cover as a diagonally downward slope path can be properly aligned with the stock alignment plate by contact with the stock alignment plate. By providing a locking and conveying device that has a conveying action section that overlaps with the action section in the direction of conveying the waste straw, even if the contact resistance between the stock end of the waste straw and the stock alignment plate changes slightly, the By applying the forced transfer action of the locking and conveying device to the sliding waste straw, the change in the posture of the waste straw can be reduced in comparison to the change in the contact resistance, and the waste straw bundle in the convergence space of the bundling device can be reduced. It is possible to perform good binding by reducing the disturbance of the posture of the material.

■ In addition, when adjusting the handling depth to actively change the protrusion length on the stock base side of the waste straw, and correspondingly changing the position of the stock base alignment plate, the position of the stock base alignment plate is , even if it is not controlled to be in a position that facilitates the most appropriate stock alignment with respect to the stock end of the waste straw, as shown in (■) above, the posture of the waste straw remains unchanged regardless of some change in contact resistance. Since conveyance can be performed with less disturbance, relatively rough control means may be employed as the position control means for the stock alignment plate, which is advantageous in that the control means does not become complicated.

■Furthermore, the means for forcibly transferring the waste straw is not a supporting conveyance device that clamps the waste straw, but a locking conveyance device that transports the waste straw in a locked state that allows mutual movement in the direction of the culm. In addition, the locking conveyance device is configured to transport the waste straw in predetermined amounts, so that the waste straw can be moved freely in the direction of the culm, making it possible to align the stock. The advantage is that the waste straw can be transported without impeding the unique function of the transport means on the inclined path where it can be carried out well, and that it is easy to separate the following waste straw from the tied wandering straw by transporting each predetermined amount. There is also.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the structure of the present invention will be described below with reference to the drawings.

The figure shows a waste straw processing device that is configured to transport waste straw discharged from the rear of a thresher 1 mounted on a combine in a horizontal position to a bundling device 2 for tying. show.

The tying device 2 includes a string supplying section 2a equipped with a string 3 for winding the tying string around a bundled straw, a raking packer 4, etc., and a knotting section 2b equipped with a knotting bill, a string holder, etc. are vertically opposed and juxtaposed, and a focusing space B is formed between the string supply section 2a and the knot section 2b.

Then, after collecting the waste straw in an appropriate amount while scraping it into the collection space B with the scraping packer 4, it is tied by the cooperation of the string supplying part 2a and the knotting part 2b, and the bundled straw is released to the rear. It is designed to repeat the operation.

Next, the waste straw from the threshing device 1 is transferred to the bundling device 2.
We will explain the structure for conveying to.

That is, a conveyance cover 6 for receiving and placing the straw from the threshing device 1 is disposed rearwardly downward from the terminal end of the straw straw chain 5 for conveying the straw from the threshing device 1 toward the rear. A plurality of guide rods 7 are arranged side by side in the length direction of the straw culm from the terminal end of the guide rod 6 to the lower position of the focusing space B.

On the other hand, a rod-shaped frame body 8 is disposed in an opposing manner from a position above the terminal end of the feed chain 5 to a position above the focusing space B.

Then, the conveyance cover 6, the guide rod 7 and the frame body 8
An inclined conveyance path A facing diagonally downward is constructed between the
In addition, a locking conveyance claw 9a is provided on the upper part of the conveyance cover 6.
・Equipped with a locking and conveying device 9 that forcibly conveys the waste straw.

Further, at a position corresponding to the discarded straw stock base side of the inclined conveyance path A, a stock alignment plate 10 that slides and guides the discarded straw stock base end to be conveyed is provided, which is connected to the action portion of the locking and conveying device 9 and the conveyance unit. They are equipped with their operating parts located at overlapping positions in the direction.

This stock alignment plate 10 is disposed such that it is positioned closer to the inside of the machine as it approaches the terminal end, and is externally connected to a cylindrical fixed frame 11 along the length direction of the waste straw that is connected and supported by the bundling device 2. It is constructed such that its position can be freely changed and adjusted in the length direction of the waste straw culm, and is fixed at a desired position by the pressing action of a bolt 12, and extends into the focusing space B. It's being served.

According to the above structure, the conveyed waste straw is conveyed while being guided by the stock end by the stock alignment plate 10, so that the end of the stock is reliably aligned and the waste straw is adjusted according to the length of the waste straw. By changing the position of the stock alignment plate 10 in the culm length direction, the waste straw to be collected can be reliably bundled at an appropriate location in the middle in the culm length direction, facing the twenty-one dollar 3.

In carrying out the present invention, if the stock head alignment plate 10 is extended into the focusing space B as described above, the waste straw will be reliably guided into the focusing space B while preventing the stock heading from being disturbed. At the same time, it is possible to prevent unexpected posture disturbances of the waste straw during convergence.

In addition, in order to prevent such a disturbance in the posture of the waste straw during convergence, as shown in FIG. If this attitude is made to favor a downward trend in stock prices, the effect will be even more pronounced.
