Description

[Detailed description of the invention] Industrial applications The present invention relates to a reaping device for a combine harvester.

Problems to be Solved by the Invention A mowing height sensor is provided on the front side of the reaping device, and the mowing device is moved up and down while this sensor is in sliding contact with the soil surface to control and control the mowing height of the culm at a constant level. In the reaping device,
Sensors detect irregularities in the field to be harvested and mounds of soil, and move the reaping device up and down to follow these soil surfaces.Also, if the cutting height suddenly changes, the cutting height may become uneven, resulting in uneven cutting marks. Also, the reaping device is often rocked up and down, causing severe vibrations.

Means for Solving the Problem The present invention detects the soil surface on the front side of the reaping device (2) that reaps the culm while traveling with the machine body (1).
A mowing height sensor (2) is provided which moves the mowing height sensor (2) up and down to control the mowing height of the culm at a constant level.
) This cutting height sensor (on the guide plate to level out the unevenness of the soil surface in the area where the glaze slides) is installed on the front side of the combine harvester reaping device.

Functions and Effects of the Invention The soil surface where the cutting height sensor ■ slides is flattened by the guide and guide plate (a), so the cutting height sensor ■ Since the surfaces are in sliding contact and large irregularities in the soil surface are sensed, sudden vertical movements of the reaping device (2) are eliminated, resulting in stability and uneven cutting heights can also be eliminated. The cutting height sensor (3) can also be protected by the guide plate (A).

Embodiment In the illustrated example, a traveling device (■) is mounted on the lower part of the machine body (■), a threshing device (■) is placed on the upper part, and a reaping device (RIO) that can be raised and lowered by a hydraulic device (8) is mounted on the front part. It has a suspended configuration.

The reaping device (2) is provided with a support frame (2) that rotatably supports the base end at the front of the threshing device (2), and an E-shaped portion extending forward in plan view is provided at the tip of the support frame (2). A grass rod (0) is provided, and a grass rod (2) is provided at the tip of each of the grass rods (to).

A pulling device ω is provided on both left and right sides above the grass dividing rod (T), and a clipper-shaped cutting blade (2) is provided at the rear end of the grass dividing rod ω.

A pair of raking devices 0 are provided above the cutting blade (2), and a stock head conveying chino (2) and a tip conveying chino (Qe) are mounted further above.

The hydraulic system (8) has a base pivotally supported on the front part of the aircraft body (2),
The other end is pivotally connected to the rear part of the support frame (2). Q71
is a solenoid valve, which is interlocked and connected to the hydraulic lever (to) via an operating wire, and by operating this hydraulic lever [F], it is possible to switch between sending oil from the hydraulic pump to the hydraulic system ■, draining oil, and shutting off these. The reaping device (2) is moved up and down.

The cutting height sensor (3) is attached to the tip of the weeding rod (1) on the − side, and the sensor ) extends rearward and diagonally downward on the outside of the branch rod O[Il.

A switch is provided in the sensor box υ that is linked to the up and down movement of the actuator 4, and the solenoid valve α is
The solenoid valve O is switched to the ascending and descending sides by vertical swinging of the actuator (to) to operate the hydraulic system), and the ground height of the reaping device (2) is kept constant. The configuration is such that it is controlled as much as possible.

(on the guide plate) is provided in front of the cutting height sensor (3). The guide plate) has a curved plate shape, and the guide plate has a curved plate shape.
It is swingably supported at the tip and biased downward by a spring (■).

The mowing height sensor (2) may be of a non-contact type and may be provided on the guide plate (2) on the front side.

When power is transmitted to each part and the hydraulic lever ω is operated to switch the solenoid valve q71 to the oil drain side, the hydraulic system (8)
When the hydraulic pressure is released, the reaping device (■) descends and the guide plate () and the actuator blade touch the ground.

When the machine (1) moves forward by aligning the cutting body ■ with the planting row of the culms, the guide plate ) is pressed against the soil surface by the spring ■, leveling out the mounds and unevenness of the soil. .

When the actuator rod slides on large irregularities in the leveled soil surface and the actuator senses the depressions in the soil surface and swings downward, the solenoid valve q'? )
is switched to the lowering side and the reaping device (2) is moved by the hydraulic device (8).
) is lowered, or conversely, when a convex portion on the soil surface is detected and swung upward, the solenoid valve G71 is switched to the upward side to raise the reaping device (2). Also, if the soil surface is level and the actuator (to) does not detect changes in unevenness,
Switch the solenoid valve Q71 to the cutoff side and operate the reaping device■
The vertical movement is fixed relative to the aircraft ■. In this way, the height above ground of the reaping device (2) is controlled at a constant level by the cutting height sensor ■.The six-hulled culm is raised upright by the lifting device ■, and its base is cut by the cutting blade ■ and scraped. While being conveyed by the loading device 0, they are merged and focused at the center. The stock base of the culm is held by the stock transport chain υ, and the tip part is held by the stock transport chain qe and transported upwards, and during the transfer, the grip of the stock base is released and the culm assumes a horizontally suspended position. The grain is sent to the threshing device■, where it is threshed and sorted.
