Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reciprocatingly movable stock end pressing for knocking the stock ends of straws discharged from a threshing device by a carrier device in a sideways posture. The present invention relates to a stock aligning device configured by a plate and an exhaust straw processing mechanism including a binding device. 2. Description of the Related Art The above-mentioned waste straw processing mechanism is used for harvesters,
It is a device that binds and shreds the discharged straw discharged from the threshing device installed in the combine, etc., but in the binding process state, the harvester artificially supplies grain culm, so the threshing device The end position of the straw discharged from the plant is not constant, and in the combine harvester, by changing the cutting culm culm length and adjusting the handling depth frequently,
In many cases, the stock end position of the straw discharged from the threshing device is not constant. Therefore, from the post-treatment surface such as sun-drying, it is desirable to perform the bundling process in a state where the stock ends of the waste straw are provided and the binding position from the stock ends is constant. Therefore, as an example of means for dealing with this, Japanese Patent Publication No. 57-54
As disclosed in Japanese Patent Publication No. 87, there is a mechanism for automatically moving a guide plate for aligning stock ends in the direction of the straw of the discharged straw according to the position of the stock end of the discharged straw. The guide plate type described above is effective when the discharge straw is relatively hard and strong, but when the discharge straw is soft and weak, the discharge straw is a guide plate. When you start contacting with, there is a case where stems are broken and the stocks are not fully stocked. Therefore, as an example of means for solving this problem, a swing-driving stock end pressing plate as disclosed in Japanese Utility Model Laid-Open No. 56-8131 is provided.
Although there is a structure for forcibly striking the stock ends, this reciprocating motion mechanism such as a swing drive type requires a wider device space than the guide plate structure. Here, an object of the present invention is to use a stock aligning device equipped with the above-mentioned forced-driving stock end pressing plate to neatly align the stock ends and to bind the stock ends at a certain position. Is to get. The feature of the present invention resides in that in the mechanism for treating discharged straw described above, a pair of position sensors for detecting the presence or absence of the discharged straw are provided in the stock root portion on the conveyance route. In the body direction, and arranged in a fixed position relative to the stock alignment device, the reciprocating operation range end of the stock end pressing plate in the stock alignment device and the position of the pair of the position sensors substantially correspond to each other, There is a drive control mechanism for moving the stock aligning device and the bundling device in the same direction in the same direction in the same direction as the stock end of the drainage straw so that the stock edge of the stock straw is located in the same direction. The action and effect are as follows. With the above construction, if the position sensor on the tip side of the pair of position sensors is in the detection state and the position sensor on the stock end side is in the non-detection state, the stock end of the discharged straw is Is located between both position sensors, and in this state the stock end of the discharge straw is fed into the working range of the stock end pressing plate, the stock is properly aligned and the stock end is kept constant. Is bound at the position. And, for example, if both position sensors are in the non-detection state, the discharge straw will not be sent to the stock alignment device, so until the position sensor on the tip side becomes the detection state, the drive control mechanism keeps the stock alignment device and the binding. Move the device. Also, if both position sensors are in the detection state,
Since the middle of the drainage straw stem culm will be sent within the working range of the stock end pressing plate, the drive control mechanism will align stocks in the opposite direction to the above until the position sensor on the stock end side becomes undetected. The device and the binding device are moved. As described above, the waste straws are bound at a fixed position from the stock end while aligning the stock ends. As described above, it is possible to bind the discharged straws discharged from the threshing device in a non-uniform state while automatically aligning the stock ends and at a fixed position from the stock ends. As a result, the efficiency of waste straw treatment is improved, and the post-treatment after binding is also advantageous. Further, by making the working range of the stock end pressing plate and the interval of the position sensor coincide with each other, the working range of the stock end pressing plate can be effectively used without waste, and the working range of the stock end pressing plate is set small. It is also possible to make the entire discharge straw processing mechanism compact.

Exhaust straw processing mechanism. Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mounted on a harvester or a combine, and is a source of waste straw which is carried out of a threshing device by a transport device in a sideways posture. The present invention relates to a waste straw processing mechanism configured to bind the waste straw while aligning the side ends. In a harvester, a worker directly feeds the cut grain culm into a feed chain of a threshing device by hand, so that the position of the end of the waste straw discharged from the threshing device on the side of the plant base. Is often not constant, and even in combine harvesters, the handling depth control is performed according to the change in the length of the cut grain culm, so the position of the end on the plant base side of the straw discharged from the threshing device is Often not constant. In this case, from the viewpoint of post-processing such as solar drying performed by making the waste straw independent, it is desirable to perform the bundling process by aligning the end of the waste straw on the stock side. [0003] Therefore, for example, Japanese Utility Model Application Laid-Open No.
As disclosed in the publication, a position sensor for detecting the position of the end of the straw near the base of the stack is provided with a stock end receiving plate for receiving the end of the base of the straw near the end of the straw that is conveyed from the threshing device. In preparation for the above-mentioned stock end receiving plate, the moving end mechanism moves the stock end receiving plate to the position of the stock end side end portion of the discharged straw based on the detection of the position sensor by the moving mechanism. Some are configured to move along the body direction. [0004] In the structure of the prior art described above, the stock end receiving plate is of a fixed type, and is merely configured to receive and guide the end of the exhaust straw on the stock base side. In such a fixed stock end plate, when the drainage straw is relatively soft and weak, the stock straw end may break when it is received by the stock end plate. Yes, it is not possible to orderly align the ends of the waste straws to be bound together on the root side.
As a result, it may not be possible to properly perform sun-drying, in which the exhaust straw is self-supporting. As described above, it is necessary to align the end portions of the drainage straws on the base side immediately before binding the waste straws. For this purpose, a drive type of knocking the end portions of the waste straws on the base side is aligned. The configuration of the stock end pressing plate is effective. Then, based on the detection of the position sensor that detects the position of the end portion of the stock straw side,
It is necessary to configure the drive type stock end pressing plate so as to move it along the culm direction of the discharge straw. However, the tap-driving type stock end pressing plate has a high function of aligning the end of the stock stirrer on the side of the stock stirrer, but the stock end pressing plate itself is driven by tapping, as in the structure of the prior art. The position sensor cannot be directly attached to and supported by the stock end pressing plate, and it is difficult to move the position sensor and the stock end pressing plate together. INDUSTRIAL APPLICABILITY According to the present invention, in the discharge straw processing mechanism, the position of the stock aligning device including the position center can be precisely adjusted so that the stock-side end of the discharge straw can be satisfactorily knocked and aligned by the drive-type stock end pressing plate. It is intended to be configured as. The feature of the present invention resides in that the discharge straw processing mechanism is configured as follows. Align the transport device that conveys the discharged straw after threshing in a sideways posture, the binding device that binds the discharged straw that has been transported by the transport device, and the end on the stocker side of the discharged straw that has been transported by the transport device. A stock aligning device is provided, and the stock aligning device is a stock end pressing plate that knocks and aligns the stock-side end of the discharge straw, a drive mechanism that knocks the stock end pressing plate, and a stock end pressing plate before knocking and aligning. Equipped with a position sensor that detects the position of the end part of the drainage straw on the stock base side, the stock end pressing plate and the position sensor are mounted on a support frame fixed to the drive mechanism, and can be moved in the direction of the straw of the drainage straw. In addition, based on the detection of the position sensor, the stock aligning device equipped with a stock end pressing plate and a position sensor is provided with a position control mechanism for moving and operating along the culm direction of the discharge straw. . [I] With the configuration according to the present invention, when the discharged straw after threshing is conveyed in the sideways posture by the conveying device, the stock end pressing plate driven by a knock in the stock aligning device causes The ends of the discharged straws on the side of the base of the stock are knocked and aligned, and the ends of the discharged straws on the side of the stock are aligned at substantially the same position in the binding device. In this case, if the waste straw is long, the distance from the binding position of the binding device to the stock end side of the waste straw becomes long, so that the stock end side end of the waste straw always contacts the stock end pressing plate of the stock alignment device. Then the straw is about to be bent. When the waste straw is long as described above, the position control mechanism based on the detection of the position sensor moves the stock alignment device including the stock end pressing plate and the position sensor in a direction away from the binding position of the binding device, The stock stirrer of the stock aligning apparatus is automatically adjusted to a state in which it is easy to beat and align the end of the straw near the base of the stock by the stock end pressing plate. Conversely, if the straw is short, the stock end side end of the straw is separated from the stock end pressing plate of the stock aligner, and the stock straw side end of the stock straw is pressed by the stock end pressing plate of the stock aligning device. Tapping may not be performed properly. When the waste straw is short in this way, the stock control device having the stock end pressing plate and the position sensor is operated to move in the direction approaching the binding position of the binding device by the position control mechanism based on the detection of the position sensor. In addition, the stock stirrer of the stock stirrer of the stock stirrer by the stock end pressing plate of the stock stirrer is automatically adjusted to a state where the stapling is properly performed. [II] According to the present invention, a stock edge pressing plate and a position sensor are attached to a support frame fixed to a drive mechanism of the stock edge aligning device, and the stock edge aligning device equipped with the stock edge pressing plate and the position sensor. Is configured to be moved and operated in the direction of the culm of the exhaust straw. In this way, when the position sensor is configured to be repositionable, the mounting position of the position sensor is integrated with the support frame of the drive mechanism equipped with the stock end pressing plate that is moved and operated based on the detection result of the position sensor. This can be achieved by a structurally simple mechanism that does not require a dedicated means for changing the position of the position sensor. Further, the position sensor can be supported without difficulty by providing the position sensor at a fixed portion of the stock aligning device, which is called a support frame, rather than at the stock end pressing plate that is driven by being knocked in the stock aligning device. As described above, in the waste straw processing mechanism,
Compared to the structure of the prior art with a fixed stock end receiving plate,
By moving the stock alignment device having the stock end pressing plate and the position sensor driven by tapping in the direction of the culm of the straw, the stocker side end of the straw can be beaten in order. . When the waste straws are bound in the state where the base side ends are aligned in this way, the bound straws can be made to stand up easily and self-sustainingly, and can be dried in the sun. By mounting the stock end pressing plate and the position sensor on a supporting frame fixed to the drive mechanism of the stock aligning device so as to adjust and move in the direction of the culm of the straw to be discharged, Since the position of the position sensor can be adjusted and supported by using the structure for position adjustment, it is advantageous in terms of simplification of the structure, and in terms of securing the reliability of the position sensor itself. But it is advantageous.
