Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a straw binding machine equipped with a stock alignment device for aligning the ends of threshed straw that is carried out from a threshing device in a horizontal position.

Conventional technology Conventionally, as shown in Fig. 3, among a pair of sensors 5H to 8K that detect the position of the end of the straw, the sensor SH on the tip side is in the detection state and the sensor SK on the end of the plant is in the non-detection state. In this state, the end of the straw stock is located between the two sensors, and the stock alignment plate is oscillated within a range that corresponds to the spacing between the two sensors, and the straw stock is positioned between the two sensors. It was designed to align the ends of the stocks that were sent into position.

Problems to be Solved by the Invention However, according to the prior art, the sensors SH and S
When there is a main stream of the stock end between K and K, the stock alignment board is at a proper position with respect to the stock end, so it is in a stopped state and does not move toward the culm. As the culm length changes, the main stream of the stock end comes to be near the sensor SH on the tip side, and the stock end of some culms comes to be located closer to the tip side than the sensor SH on the tip side, and the sensor SH There was a problem in that the stock ends within a predetermined interval from the existing position could not be aligned.

Therefore, an object of the present invention is to solve the above problems.

The aim is to further improve the stock arrangement function.

Means for Solving the Problem The technical means according to the present invention is a stock arrangement plate 3 which is configured by a stock arrangement board 3 that can swing back and forth to align the ends of the straw that has been carried out from the threshing device 1 in a horizontal position. It is equipped with an aligning device 4 and a bundling device 5, and is provided with a pair of sensors 21a and 21b for detecting the position of the end of the waste straw.
In the straw tying machine, which is configured to be able to move the stock arranging device w4 in the straw culm direction based on the detection results of the plant end positions of the stock arranging devices 1a and 21b, the stock arranging plate 3 in the stock arranging device [4] is
This stock alignment action range extends from the region corresponding to the pair of stock end position detection sensors 21a and 21b to the region corresponding to a predetermined interval closer to the ear tip side than the location of the stock end position detection sensor 21a on the tip side. It is characterized by being arranged diagonally.

Functions and Effects of the Invention According to the above-described configuration, among the pair of sensors for detecting the position of the stock end of the straw, when the sensor on the tip side is in the detection state and the sensor on the stock end side is in the non-detection state, , the stock end of the waste straw is located between both sensors, and in this state, the stock alignment device is at an appropriate position with respect to the stock end, so it does not move toward the culm and is in a stopped state. When both detection sensors are in the detection state, the one-plant arrangement device moves toward the straw-discarded plant end side until the sensor on the one-plant end side becomes a non-detection state.

When both sensors are in the detection state, the stock alignment device will move toward the side of the straw tip until the sensor on the tip side is in the detection state.

Even if the main stream of the plant end fed into the single plant alignment device due to changes in culm length is located at a position corresponding to the sensor on the tip side, Since the stock alignment action range of the stock alignment plate extends to a corresponding position closer to the tip side than the corresponding position of the tip side sensor, the stock alignment plate can reliably knock and align the ends of the plants.

Example An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a threshing device, and 2 a conveyance device that carries out the straw from the threshing device and transports it backwards in a state where it is lying on its side.

A stock arranging device that has a stock arranging plate 3 that can swing back and forth to align the ends of the waste straw at the rear of the conveyor [12]! A waste straw tying machine 6 is provided, which includes a tying device 5 for concentrating and tying waste straw in a predetermined amount.

The stock is arranged on the guide rail 8 installed between the left and right side frames 7, 7 of the straw binding machine 6! 4 and binding device! ! 5 is installed so that it can slide.

9 is a transmission shaft formed in a hexagonal shape, and a scraping device 10.1
1 and 12 are mounted on an axis to rotate them, and a driving eccentric wheel 13 for reciprocating the stock end alignment plate 3 is mounted on an axis so as to be slidable. The raking devices 10.12 are connected and held by the slide frame 14 on the stock alignment device 4 side and the slide frame 15 on the bundling device 5 side, respectively, and are configured to slide integrally with them.

Further, the intermediate scraping device 11 is set at a fixed position on the main body side of the binding machine 6.

The stock alignment device 4 and the bundling device 5 are screwed onto spiral shafts 16 and 17 arranged in the same direction as the guide rail 8, and motors 18 and 19 drive the spiral shafts 16 and 17 in the forward and reverse directions. And both bags! 4 and 5 are interlocked via a drive control mechanism so that they slide in the same direction in the left and right lateral directions on the guard rail 8.

Next, to explain the control system of the drive control mechanism, a pair of sensors 21a and 21b are mounted on a frame 20 that extends from the single-plant arrangement device 4 toward the straw removal path forward, and detect the position of the straw straw end. is installed in the direction of the culm of the waste straw, and is configured such that the sensor 21 for detecting the position of the stock end becomes ready for detection operation according to the result of detecting the presence of waste straw by the sensor 21 for detecting the presence or absence of waste straw.

In the stock end position detection sensors 21a and 21b, both sensors 21a are located at the stock end of the waste straw.

21b, it is detected that the waste straw is a short culm, the motor 18 is driven in the normal direction, the spiral shaft 16 is rotated, and the one-plant arrangement device l! 4 toward the tip side of the waste straw. When the sensor 21a on the S tip side contacts the stock base, the drive of the motor 18 is stopped. Also, the stock part has both sensors 21a.

21b, it is detected that the waste straw is a long culm, and the motor 18 is driven in the reverse direction, the spiral shaft 16 is similarly rotated in the reverse direction, and the stock arrangement device 4 is moved to the opposite side of the ear in the opposite direction. It is configured to move in the direction.

The bundling device 5 is configured to actuate a limit switch by the movement of the one-stock aligning device 4, drive the motor 19 in forward and reverse directions, and follow the movement by rotating the helical shaft 17.

The stock alignment board 3 swings back and forth within a swing range, and at least this stock alignment action range is detected by the stock end position detection sensor 21a.
- Arranged obliquely with respect to the direction of detection action of the sensor 21 so as to extend from a part corresponding to the interval between the tips 21b to a part corresponding to a predetermined interval closer to the tip side than the location of the tip side sensor 21a. There is.
