Description

[Detailed description of the invention] The present invention relates to a straight-travel guiding device for a combine harvester.

In other words, in a combine that is equipped with running bodies that can operate side clutches on both sides of the lower part of the machine, and a reaping section installed in the front of the machine, the machine automatically moves in a straight line, ensuring accurate and accurate combine work. It was designed to make driving easier for the operator.

Next, the embodiment shown in the drawings will be described.

Fig. 1 is a plan view schematically showing a combine harvester with a conventional structure, in which track-type traveling bodies 11' are arranged on both sides of the lower part of the machine body, and a reaping section A is installed on the front left side. , a transport supply section 2 is disposed behind it, a threshing section 3 is further disposed on the right side, and a control section 4, a paddy receiving section 5, etc. are disposed at the rear of the machine body.

At the frontmost part of the reaping section A, weeding bodies a and a' that can advance between the rows of plants are arranged in the same manner as in the conventional structure, but the left side weeding body a is supported by the frame 6 in the longitudinal direction of the machine, and the weeding body The front support part 8 of the sensor integrated C is freely rotatably attached to the vertical shaft 7 provided at the lower front of the sensor, and the sensor integrated C is extended toward the rear in the longitudinal direction of the fuselage.

That is, the sensor unit C is extended from the support part 8 toward the rear of one side of the frame 6 to form a bent part 9 that is one side detection part in that part, and from the bent part 9 to the other side detection part behind it. The rear end portion 10 is bent so as to straddle the frame 6 and extend rearward on the other side of the frame 6, and a bent portion is a sensing portion on one side of the rear end portion 10, which is located at a length (Ll) from the support portion 8. A protrusion 11 is provided inside the frame 9, and a protrusion 11 is provided in the same way toward the frame 6 at the rear end portion 10, which is the other side detection portion, at a position where the length (L2) is longer than the (Ll) length. 12 is provided at the position of the frame 6 corresponding to the projecting body 11, and when the projecting body 11 comes into contact with it, the traveling body 1 on the other side
A sensing actuated switch body 13 is provided at the position of the frame 6 corresponding to the projecting body 12 to operate the side clutch on the traveling body 1 on one side when the projecting body 12 comes into contact with the switch body 13. Operation switch body 1
4 will be provided.

Bullets 1515' are interposed between the sensor assembly C and the frame 60 at the front and rear positions, respectively, and when the grass division body a and the sensor assembly C move between the two adjacent stock rows BB', one side It's too close to the stock row B, so the sensor is all C.
When the detection part on one side of is strong (when it makes contact, the protruding body 11 contacts the switch body 13 and operates, and the Gero stock b' is placed in the stock row B on the other side)
If the other side detection part of the sensor unit C comes into strong contact with the other side of the sensor integrated circuit C, or if the projecting body 12 comes into contact with the switch body 14 due to the operation of the bullets 15, 15' when the projecting body 12 is moved in that direction, The ratio of the (Ll) length and the (L2) length is configured as a factor in the priority detection degree of the one-side detection unit.

Therefore, in the combine harvesting operation, the cutting plants a and a' at the front of the cutting section A are moved forward between the rows of plants and harvested, but the cutting plants a and a', which are moving forward between the rows of plants B and B', are on one side. If the switch is too close to the stock row B, the bent portion 9 of the following sensor assembly C will come into strong contact with the stock row as shown in FIG.
The side clutch of the other side traveling body 1' is disengaged, and the direction of the body is corrected in the direction of the other side, and while the direction is being corrected, the switch body 1
The sensor unit C is activated so that the projecting body 11 separates from the vehicle 3, and when the projecting body 11 separates from the body 11, the side clutch of the other side traveling body 1' is activated to engage again, and the body moves straight.

In other words, as shown in FIG.
, B', a state is created in which the branching body a and the sensor assembly C move forward in order to maintain a normal straight traveling state.

Also, as shown in FIG. 5, if the weeding body a and the sensor unit C are too close to the other side of the plant row B', the rear end 10 of the sensor unit C will be moved toward the frame 6 side, or the rear end 10 will be The projecting body 12 comes into contact with the switch body 14 and is activated by strongly contacting and being pushed by the stock b', and the side clutch of the blade-side traveling body 1 is disengaged and the direction of the machine body is corrected in one direction. ,
When corrected, the switch body 14 separates from the projecting body 12, the one-side traveling body 1 is operated to engage the side clutch again, and the body moves straight.

As described above, the present invention provides a combine harvester that is equipped with traveling bodies 11' that can operate side clutches on both sides of the lower part of the machine body, and has a reaping section A installed in the front section of the machine body. A sensor integrated C having a -blade side detection part and the other side detection part behind it is provided at a position near the blade side, and the sensor is moved between two adjacent stock rows B and B' to plant b'. This is because a sensor integrated C is installed that can disengage the side clutch of the other traveling body 1' when it approaches the detection section on one side while making contact, and disengage the side clutch of the traveling body 1 on the other side when it approaches the stock row on the other side. , when the sensor unit C along with the cutting body a approaches either side while moving between the two plant rows B', the two traveling bodies 11' receive the contact action with the plant b and b'.
Either of the side clutches can be activated to automatically correct the orientation of the aircraft, and the integrated sensor C operates reliably at the front of the reaping section A to guide the aircraft to proceed straight. It has features that allow combine harvester work to be carried out accurately and easily for the operator, and since the sensor is integrated with a detection section on the other side behind the detection section on the blade side, it is possible to operate the combine harvester accurately and easily. It has the excellent features of being able to prioritize the detection of the stock origin of the plant, sufficiently preventing the machine from getting stuck on the uncut side, and obtaining a sensor with a simple structure and higher detection accuracy. It is something that you have.
