Problems solved by technology

However, in the case of using the conventional detection device, when the ground sensor slips on the ground, the ground sensor will be hooked on the bumps or clods on the ground, and at this time, a large bending force, etc. will easily act. On the sensor support part such as ground sensor
Unsuitable force will act on the detection part

no. 1 Embodiment approach

[0042] Such as figure 1 As shown, this Combine harvester consists of a ride-on driver's part equipped with a driver's seat 2 and an engine (the Not shown) of the prime mover constituted. On the support part 4 positioned at the front part of the body frame 3, the base end part of the pretreatment part frame 11 of the harvesting part 10 is connected freely around the horizontal axis. On the rear end side of the body frame 3, a threshing device 5 and a grain tank 6 for storing grains such as rice and wheat after threshing are provided.

[0043] A piston rod of a hydraulic lifting cylinder (corresponding to a hydraulic cylinder) 8 is connected to the above-mentioned preprocessing part frame 11 . By telescopically operating the lifting cylinder 8, the pre-processing unit frame 11 swings in the up and down direction, thereby lowering the harvesting unit 10 to a working position close to the ground and lifting the harvesting unit 10 from the ground to a non-working position. Betw...

no. 2 Embodiment approach

[0066] Figure 10 The harvesting part 10 of the Combine harvester which concerns on 2nd Embodiment of this invention is shown. In this harvesting section 10, except for the location and the number of installations of the harvesting section's height-to-ground detection device 20, the rest of the structure is the same as that of the above-mentioned Kangbaiying harvester in the first embodiment. Below, only the differences will be described. point.

[0067] That is, the height detection device 20 of the harvesting section to the ground is arranged in a plurality of grass-distributing frames 16 arranged in the lateral direction of the body, and is also a plurality of grass-distributing frames inside the body than the two outermost grass-distributing frames 16 positioned in the lateral direction of the body. 16 on the front end.

[0068] In this way, if a plurality of detection devices 20 for the height of the harvesting section to the ground are installed, even if the ground sen...

no. 3 Embodiment approach

[0070] Figure 11 , FIG. 12 has shown the main part of the harvesting part height detection apparatus 20 in the Combine harvester which concerns on 2nd Embodiment of this invention. Among them, a brake bolt (an example of a stopper) 55 is attached to the bearing portion 40a of the gear box 40 supporting one end side of the input shaft 41 . The stop bolt 55 plays a blocking role relative to the flat portion 41 a provided at the end of the input shaft 41 inside the gearbox 40 . Thereby, a structure is formed in which the lowering limit of the ground contact sensor 21 can be freely adjusted and set so that the ground contact sensor 21 becomes the lowering limit when the detection unit 22 reaches the operation limit.

[0071] That is to say, even in the state where the ground sensor 21 is still grounded, the operating force that makes the automatically traveling body retreat and swing downward continues to act on the ground sensor 21, and as the ground sensor 21 descends and swin...

Abstract

A harvester, which has a cutting portion(10) having a frame(16) connected fluctuatingly and liftably relative to a travelling body, and in which a ground height detecting apparatus(20) is provided with a ground sensor(21) vertically fluctuating relative to the frame(16) and a detecting portion(22) for detecting the ground height of the cutting portion based on a fluctuating angle of the ground sensor, wherein the apparatus(20) comprises a supporting body(25) rotatably connected relative to the frame around a rotational axis center(Y) in an anteroposterior direction of the traveling body, while supporting the ground sensor(21) and the detecting portion(22); and a compressing unit for rotating the supporting body in a reference rotational position for the frame.

Description

technical field [0001] The present invention relates to harvesters such as Combine. More specifically, the present invention relates to a harvester in which a harvesting section with a grass-distributing frame can freely swing up and down with respect to a traveling body, and the height-to-ground detection device of the harvesting section is provided with a grounding sensor and a detection section. The ground sensor can freely swing up and down relative to the above-mentioned grass-dividing frame; the detection part detects the height of the above-mentioned harvesting part to the ground according to the swing angle of the ground sensor. Background technique [0002] The harvester is provided with a detection device for detecting the height of the harvesting section above the ground. If the detection height obtained by the height-to-ground detection device is below the set height, the harvesting section is controlled so that it moves closer to the traveling body. rise automa...
