Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a threshing straw tying machine equipped with a stock alignment device and a tying device for aligning the ends of threshed straw that are carried out from a threshing device in a sideways posture. Regarding.

BACKGROUND ART A control means for automatically changing the position of a stock alignment device and a bundling device along the culm direction of waste straw based on the detection result of the end position of waste straw is already known.

Conventionally, as such movement control means, the stock alignment device and the bundling device were moved integrally regardless of the size of the difference in culm length. In other words, the tying device was configured to integrally move to follow even minute movements of the stock alignment device when there is little change in the culm length difference.

Problems to be Solved by the Invention However, according to such prior art, the tying device moves more often in the direction of the culm during tying, resulting in frequent tying errors due to movement of the string, making it difficult to obtain stable tying performance. do not have.

Furthermore, the movement of the binding device more than necessary increases wear on the sliding portion, resulting in a problem of lack of smoothness.

The present invention aims to solve these problems and takes the following technical measures.

A means for solving the problem, that is, a technical means according to the present invention, includes a stock alignment device 4 for aligning the ends of the straw that has been carried out from the threshing device 1 in a sideways posture, and a binding device 5!5. A certain threshing straw tying machine is designed to change the position of the stock aligning device and the bundling device along the direction of the straw culm based on the detection result of the stock end position of a sensor 26 that detects the stock end position of the waste straw. Along with configuring.

The present invention is characterized by a related structure so that the bundling device does not follow the movement of the stock arrangement device by a small amount of movement.

Function According to the above-mentioned configuration, when the sensor detects the position of the end of the straw that is carried out from the threshing device in a sideways posture, the motor is driven and controlled by the command of this sensor, and the helical shaft is rotated. , the stock alignment device is moved and adjusted to a predetermined position in the direction of the culm of the waste straw. When the amount of movement of the stock arrangement device exceeds a predetermined range, a limit switch is turned on to drive and control the bundling motor, and the bundling device is moved to follow by rotation of the helical shaft.

Effects of the Invention Therefore, according to the present invention, when there is no large change in the difference in culm length, the movement of the stock alignment device alone is controlled and the binding device is not moved unnecessarily. The problem has now been resolved.

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

Reference numeral 1 denotes a threshing device, and 2 denotes a conveyance device that carries out the waste straw from the threshing device toward the rear in a sideways state.

Transport device! At the rear of the straw tying machine 2, there is a stock arranging device 4 having a reciprocally swingable stock end aligning plate 3 for slapping and aligning the ends of the waste straw, and a tying device 5 for concentrating and tying the waste straw into a predetermined amount. There are 6.

A stock arrangement device 1f4 and a bundling device 5 are slidably installed on a guide rail 8 installed between the left and right side frames 7, 7 of the straw bundling machine 6.

Reference numeral 9 denotes a transmission shaft formed in a hexagonal shape, and a raking device 10/1
1 and 12 are mounted on an axis to rotate them, and a drive 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 and 12 are connected and held by a slide frame 14 on the one-stock arrangement device 4 side and a slide frame 15 on the binding device 15 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 helical shafts 16 and 17 disposed in the same direction as the guide rail 8 via supports 18 and 19, and are rotated by motors 20 and 21. 16 and 17 are driven in the forward and reverse directions so that both devices 4 and 5 slide on the guide rail 8 in the same direction in the left and right lateral directions through a drive control mechanism.

Reference numeral 22 denotes a slide rod that is slidably provided on the slide frame 15 on the side of the binding device 5, and is connected to the motor 21 on the binding side.
The limit switches S1 and S2 for forward and reverse driving are connected and held to the slide frame 14 on the side of the stock arrangement device 4 through slide cam plates 23 and 24 that operate the limit switches S1 and S2. When reciprocating in the left and right lateral directions, the cam surface 23a or 24a of the slide cam plate 23.24
, the limit switch S1 or S is turned on, and the binding device 5 is driven by the forward and reverse rotation of the motor 21.
is configured to move following the stock alignment device 4, and is also a single stock alignment device! The configuration is such that the limit switches S1-S are not turned on within the movement range of 4 and L3. In addition, the binding device 5 has a limit switch S1.
After moving with respect to S8, it is configured to stop while maintaining a distance of L□・L8.

Next, to explain the drive control plan for the stock arrangement device, a pair of sensors 26a and 26b are installed on the frame 25 extending from the stock arrangement device 4 toward the straw removal path forward to detect the position of the end of the removal straw. is installed in the direction of the culm of the straw, and is determined by the detection result of the presence of straw by a sensor 27 for detecting the presence or absence of straw, which is placed and supported on the starting end side of the intermediate fixed raking device 11 in the vicinity of the straw conveyance device 2. The stock end position detection sensor 26 is configured to be in a detecting state.

Then, in the stock end position detection sensors 26a and 26b, if the stock end of the waste straw does not come into contact with both sensors 26a and 26b, it is detected that the waste straw is a short culm, and the motor 20 is driven in normal rotation, The helical shaft 16 is rotated to move the stock arranging device 4 toward the tip side of the straw. When the sensor 26a on the tip side contacts the stock base, the drive of the motor 20 is stopped. In addition, both sensors 26a and
26b, it is detected that the waste straw is a long culm, and the motor 20 is driven in the reverse direction, the spiral shaft 16 is similarly rotated in the reverse direction, and the stock alignment device 4 is moved in the opposite direction to the opposite direction. The configuration is such that it can be moved to
