Description

DETAILED DESCRIPTION OF THE INVENTION The present invention automatically maintains the height above the ground, that is, the lowest position of the cutting height, of a comparatively wide reaping pretreatment section, such as in a so-called direct current combine harvester of the general input threshing type. This is a reaping/harvesting machine equipped with a ground sensor such as a ground sensor, specifically, a reaping/harvesting machine with a length extending over the entire width or almost the entire width of the reaping pre-processing part, which can be driven up and down with respect to the machine. The present invention relates to a reaping harvester that is equipped with a ground sensor for raising and lowering the shin part of the cutting front, which has a bridge body and a plurality of ground contact parts projecting downward from locations spaced apart in the width direction on the lower surface of the bridge body.

As mentioned above, a sensor configured so that the entire length of the lateral I depression does not come into contact with the ground, but only partially, has a smaller ground contact area, which can reduce running resistance and wear caused by contact with the ground. In the case where the plurality of ground contact parts are integrated with the tower body by means such as hammering, or which are fixed integrally by means such as welding, if the ground contact parts mentioned above become worn or damaged, there will be no damage in most cases. It was necessary to replace the entire sensor, including the oar body, which was not worn out or damaged, which resulted in a large loss in terms of running costs.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks through simple improvements, and in order to achieve that purpose, the configuration of the reaping and harvesting machine according to the present invention is such that a plurality of ground sensors are connected to each other. The bridge body is configured such that the parts are detachably attached to the bridge body.

The effects of the present invention having such a characteristic configuration are as follows.

By configuring the plurality of grounding parts, which are most likely to wear and break during work, to be detachable from the bridge body, when the grounding parts are worn or damaged,
It is only necessary to replace the worn or damaged small ground contact parts, and the tower body and the ground contact parts that are not yet worn or damaged can continue to be used as they are. Therefore, the number of replacement (expendable) parts for the ground sensor as a whole can be limited to the minimum necessary, making it extremely advantageous in terms of running costs.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Figure 1, there is a reel (6) that scrapes the planted grain culm toward the rear of the machine (1), and a cutting blade (7) that reaps the scraped culm.
, an auger (8) that receives the cut culm, collects it in the center side in the lateral direction of the machine, and sends it out to the rear of the machine (L), transports the cut culm to the rear of the machine (1) with the tip in front The reaping pre-processing section (2) equipped with a conveyor (9) is thrown to the main machine (1+) so as to be able to move up and down for 100 mJ, and the reaped husk culm supplied from the reaping pre-processing section (2) is threshed. Device (4)
, the tank (5) for collecting grains after threshing is connected to this machine (1).
) is installed at the rear, and is further provided with a crawler traveling device (23+) and a driving control unit (SL) to form a general input type comparator.

A lifting ground sensor (3) is provided at the bottom of the reaping pre-processing section (2), and in detail, this sensor (3) covers the entire width or almost the entire width of the reaping pre-processing section (2). The front end of the length of the bamboo shoots (3A) is treated in the pre-reaping treatment section (
The bridge body (8A) is pivotally supported on the support hunches in 2), and its rear end is connected to the connecting rond (11) of the mechanism that automatically controls the drive up and down of the reaping pre-processing section (2) in 1a. A plurality of ground contact portions (3B) projecting downward from locations spaced apart in the width direction on the lower surface of the center portion projecting downward are connected to the bridge body (8A) via bolts (10). It is configured to be detachable.

The automatic control mechanism is comprised of the connecting rod (11), link mechanism (I2), and wire mechanism, and transmits the grounding action of the sensor (3) to the lifting operation mechanism (Bl, which will be described later). The middle (E) is the sensor (3)
This is a spring that urges the ground surface.

Further, (b) is a stopper that restricts the lower limit of the sensor (3).

The lifting operation mechanism (Bl) is composed of the wire mechanism (swinging link (+5) that is interlocked with the lever, a connecting rod threshold, and a plate-shaped frame I that rotates integrally with the lever (L4)), and On the negative side of the link (15), a hydraulic cylinder (19) for lifting and lowering the reaping pre-processing section (2) is provided.
The spool of the valve (3) interposed in the hydraulic circuit to
20a) are J-connected, and a long hole (
The wire mechanism ([3)] is interlocked and connected through one line.

To explain the operating state of the pre-reaping treatment section (2) by the sensor (3), when the manual setting lever (14) is set to the lowered position, the spool (20a) is pushed in and the pre-reaping treatment section (2) is activated. starts descending and the sensor (3) detects the ground surface, the wire mechanism (13) acts on the tension side and the tension force moves the spool (20a) from the pushed state to the neutral position. , and the front self-reaping pre-processing section (2) stops descending. At this point, the manual setting lever (+4) Vi is in the neutral position.

When the sensor (3) detects a protrusion during harvesting in such a state, the wire mechanism (+3) acts in the pulling direction of the spool (20a), causing the spool (20a) to extend. state, and the reaping pre-processing section (
2) begins to rise, and upon sensing the rise, the operator resets the manual setting lever (14) to the lower position, thereby switching the pre-reaping process (2) to the lowering state again and returning to the reaping position. let

The ground contact 11 (8B) is located above the lateral external force area and the front area of the inclined wall surface (8a), (8a), (8b).
), it is possible not only to make the ground contact part (3B) relatively small and reduce contact wear with the ground, but also to reduce the ground contact part (8B) during left and right steering operations. ) can be made small.
