Description

  The present invention relates to a combine control device, and more particularly, to a combine control device in which a plurality of switches are arranged in a grip portion of an operation lever that performs an elevating operation of a preprocessing unit, a turning operation of a traveling machine body, or a shifting operation.

  As an operation lever equipped in the driver's seat of the combiner, it is possible to lift and lower the pre-processing unit for harvesting cereals and to turn the traveling machine body with a single operation lever (for example, a multi-steering lever). There is. And, in the grip part of this multi-steering lever, by providing a horn switch that sounds an alarm horn, a changeover switch that can be switched to shallow handling or deep handling by adjusting the handling depth of the cereal, etc. Even when operating the multi-steering lever, the operator can instantly sound an alarm horn if necessary to ensure work safety. The threshing work can be performed at an appropriate handling depth by adjusting the handling depth (see, for example, Patent Document 1).

  Further, according to another conventional example, the pre-processing unit is moved to a predetermined lowering position in conjunction with the pressing operation on the grip portion of an operation lever (for example, a main transmission lever) that performs a forward / reverse switching operation of the traveling machine body. What provided the auto set switch for making it descend | fall is well-known (for example, refer patent document 2).

  1 and 2 are external perspective views of a combine to which the present invention is applied as viewed from the left and right front sides, in which the combine 10 is supported by left and right crawler travel devices (travel units) 12 and 12. The traveling machine body 13 is provided, and on the left and right sides of the traveling machine body 13, a driver's seat 14 and a grain tank 16 for temporarily storing the grain behind the driver's seat 14 are disposed. . An engine room (not shown) is defined on the rear rear side of the driver's seat 14, and one side of the engine room is covered with an engine cover 25. Further, a threshing unit 18 is disposed on the left and right other sides of the traveling machine body 13, and a pre-processing unit 20 is disposed in front of the traveling machine body 13 so as to be movable up and down.

  The pre-processing unit 20 includes a divider 21 for weeding the cereals, a pulling device 22 for causing the overlaid cereals, and the cereals cut by the pre-processing unit 20 are fed into the feed chain 23. To the threshing unit 18, threshing and sorting in the threshing unit 18, and the selected grain is lifted and transferred and temporarily stored in the grain tank 16. The stored grains are erected out of the machine by a discharge auger 24 which is erected substantially vertically from the rear part of the grain tank 16 and has a long tube which can be swung and undulated.

  As shown in FIG. 3, the driver's seat 14 has a seat seat 15 on the center side, and has a multi-steering lever 26 erected in a tiltable manner in front of the seat seat 15.

A sub-transmission lever 32 tilted along the linear guide groove 31, a work implement clutch lever 33 tilted along the linear guide groove behind the sub-shift lever 32, and a cutting A clutch lever 34 and the like are disposed.

  The multi-steer lever 26 is an operation lever that performs an on / off operation of the side clutch and an up / down operation of the preprocessing unit 20, and the preprocessing unit 20 can be moved up / down by tilting from the neutral position in the longitudinal direction of the machine body. In addition, left and right side clutch operations can be performed by tilting in the left-right direction from the neutral position. The main transmission lever 30 is configured to be capable of switching between forward and backward (F, N, R) of the traveling machine body 13 and a continuously variable transmission operation from 0 start to maximum speed.

  FIG. 4 is a view of the multi-steering lever 26 and the main transmission lever 30 as viewed from above. A direction correction (right) switch 35 and a direction correction (left) switch 36 for finely adjusting the direction by disengaging only the side clutch are arranged at the tip grip portion of the multi-steer lever 26. Right) When the switch 35 is pressed, the aircraft traveling direction is corrected in the right direction, and when the direction correction (left) switch 36 is pressed, the aircraft traveling direction is corrected in the left direction. In the present embodiment, these direction correction switches 35 and 36 are constituted by non-lock type push button switches. When these switches are pressed, they are turned on, and when released, they are turned off.

At the tip of the grip portion of the main speed change lever 30, a forced scratching switch 37 whose pushing direction is the left and right sides of the machine is provided. When the forced scratching switch 37 is pushed, It has the function of rotating the star foil (not shown) of the pre-processing unit 20 and performing a scraping operation, thereby preventing spillage of the harvested cereal meal. Further, below the forcible raking switch 37, a handling depth manual (shallow) switch 38 and a handling depth manual (depth) switch 39 are arranged in parallel so that the pushing operation direction is the front and rear of the machine body. When these manual operation depth switches 38 and 39 are pressed, a treatment depth motor (not shown) is driven so that the treatment depth of the cereals in the treatment depth conveying device (not shown) becomes shallow or deep. Adjusted to be. Further, below the forced raking switch 37 and on the rear side of the handling depth manual switches 38 and 39, an overturning cutting switch 40 is disposed so that the pushing operation direction is the front and rear of the machine body. When the lodging cut switch 40 is pushed, the raising speed of the chain of the raising device 22 is increased to cause the fallen grain straw to be raised. Each of these switches is also composed of a non-lock type push button switch.

  Although not shown in the drawings, in other places, for example, a cutting height position control release switch, an automatic lowering switch for automatically lowering the height of the preprocessing unit 20 to the cutting height, and a cutting end are set in advance. An automatic ascent switch or the like for raising the height of the preprocessing unit 20 to a certain height is provided.
