Abstract

PURPOSE:To prevent the clogging of a running direction sensor with soil by placing a sensor box supporting an actuator rotating backward on the contact thereof with a left or right grain straw foot on the upper outward side of a straw-dividing lever at the top end of a reaping device. CONSTITUTION:When an actuator 2 comes into contact with the foot portion of a left or right grain straw in the running direction of a reaping device during a reaping work thereof, the actuator 2 is backward rotated to detect the grain straw. A sensor 3 supporting the actuator 2 is placed on the upper outward side of a straw-dividing lever 4 to form a space on the downward side of the sensor box 3. The sensor box is not clogged with soil to smoothly rotate the actuator.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a strike sensor for combine harvesters and the like, and can be used for combine harvesters, binders, and the like.

BACKGROUND TECHNOLOGY AND PROBLEMS TO BE SOLVED BY THE INVENTION] A strike direction sensor such as an unbine is installed at a position close to the soil surface at the tip of a reaping device at the front of the vehicle body, and is located at a position close to the soil surface with respect to the running direction of the reaping device. Based on the detection result, the vehicle body is steered so that the reaping device travels along the row of grain culms.

Since this strike direction sensor detects the stock base of the grain culm, it is installed at a position close to the soil surface, and when this strike direction sensor comes into contact with the stock base of the grain culm, an actuator that rotates backward is activated. If this type of reaping device is installed on the upper side of the grass dividing rod at the tip of the reaping device, mud may become clogged between the sensor box that supports the actuator and the grass dividing rod during reaping operation, which may prevent the actuator from operating. may not be performed correctly.

Therefore, an object of the present invention is to prevent mud from clogging the strike direction sensor so that it can operate reliably.

Means for Solving the Problems The present invention provides a sensor box (3) that supports an actuator (2) that rotates rearward by contacting the stock base of the left and right grain culms with respect to the traveling direction of the reaping device (1). ) is configured as a strike direction sensor of a combine harvester or the like, which is located above and outside of the dividing rod (4) at the tip of the reaping device (1).

Functions and Effects of the Invention During reaping work, when the 7 cutuator (2) comes into contact with the base of the grain culm on the left and right with respect to the traveling direction of the reaping device (1), this actuator (2) moves backward. It rotates to detect grain culms, and based on the detection results, the vehicle body is steered and controlled.

The sensor box (
3) is the reaping device! (1) This sensor box (3
) is open at the bottom, and this sensor box (3)
Mud clogging is prevented.

Therefore, the actuator (2) rotates smoothly,
Grain culms can be detected accurately.

Example In addition, in turning, the combine harvester uses the left and right traveling device (5)
A threshing device (7) is mounted on a chassis (6) having a wheel, a reaping device (7) is mounted on the front part, and a reaping device (1) is provided on the front part.

The reaping device (1) includes a raising device (81) that raises grain culms, a cutting blade device (9) that reaps the raised grain culms, a raking device (IDI) that collects and collects the harvested grain culms; The structure includes a transfer device (lυ, etc.) that transfers the collected grain culms to the threshing device (7) at the rear.

A mounting plate aδ is provided on the upper outer side of the weeding rod (4) at the tip of the reaping device (1). This mounting plate 0 old samurai, corresponding branch rod (4)
Attach it to the weeding rod (+3) at the tip and the connecting rod (!4) that connects the lower part of the pulling device (8) and the weeding rod (4), and bypass it to the outside of the weeding rod (4). It is set up.

The strike direction sensor (1!9) consists of an actuator (2) and a sensor box (3) that supports this actuator (2).This sensor box (3) is attached to the mounting plate 0, and this sensor box ( 3) is a branch rod (4)
The actuator (2) is provided to protrude to both left and right sides of the weeding rod (4). When this actuator (2) contacts the grain culm and rotates backward, each switch is turned on.

When the actuator (2) is turned on, the latch that transmits power from the prime mover to the left/right traveling device (5) is turned off, thereby correcting and controlling the running direction of the vehicle body to the left and right.

When the reaping device (1) is moved by transmitting power through each part and moving the cutting body (13) along the rows of grain culms, the left and right grain culms are detected by the strike sensor (19).For example, the cutting rod (4) When the actuator (2) comes into contact with the grain culm on the left side and rotates backward and the switch is turned on, the power transmission to the right side running device (5) is cut off and the running direction of the car body is corrected to the right. In this way, the steering of the vehicle body is controlled based on the detection result of one grain culm by the direction sensor (one grain culm detection result), and the reaping device (1) moves along the grain culm row and harvests the grain culm. Work is done.

The strike direction sensor (19) is located on the upper outer side of the dividing rod (4) and is attached to the mounting plate (1).Since the lower part is open, the actuator (2) can be moved smoothly without getting clogged with mud. Since it rotates, it can be operated reliably.
