Description

Description: TECHNICAL FIELD The present invention relates to a spin turn control device in a combine.

(Prior Art) Japanese Patent Application Laid-Open No. 63-125478 discloses a traveling device having a spin-turn mechanism, a grain stalk cutting portion provided in front of the traveling device, and In a combine having a threshing unit for threshing the grain stalks cut by the mowing unit provided and a tilt sensor for sensing the front, rear, left and right inclinations of the body provided at a desired position, the tilt sensing sensor is such that the body is inclined by a predetermined angle or more. If the aircraft is not tilted more than a predetermined angle, it will be turned on,
The tilt sensor and the spin turn mechanism, when the tilt sensor is `` off '', spin turn disabled,
A spin-turn control device in a combine in which the tilt-sensing sensor and the spin-turn mechanism are interlocked so that the spin-turn is enabled when the tilt-sensing sensor is "on" is described.

(Problems to be Solved by the Invention) In the known device, a tilt sensing sensor and a spin turn mechanism are used. When the tilt sensing sensor is “off” (slow tilt), spin turn is disabled, and the tilt sensing sensor is “on”. In the case of "" (steep inclination), a spin turn is possible.

In a gentle inclination state, when the vehicle is spin-turned, the vehicle body turns significantly and cannot return to the original traveling direction. In a steeply inclined state, a spin turn is performed because it is desired to immediately return to the original direction when the traveling direction turns.

However, the slope in the known example is not a large slope because the slope in a flat field is symmetrical. The present invention may also adopt a known example configuration, but the present invention is directed to a case where the inclination is higher than that of the known example.

That is, as the combine moves from field to field, it crosses over high concrete ridges. Since the concrete ridges cannot be broken, the aircraft leans heavily forward and backward. Also, when working parallel to the ridge, one side rides on the ridge and is in a state just before falling. In such a case, it is inevitable that the aircraft will fall down after a spin turn.

(Object of the Invention) Accordingly, an object of the present invention is to obtain a combine that is always safe against inclination.

(Means for Solving the Problems) Accordingly, the present invention provides a traveling device 1 provided with a spin-turn mechanism, a grain stalk cutting portion 3 provided on the front side of the traveling device 1,

However, when the outer engaging claws 61 and 62 are both moved outward and engaged with the left and right fixing claws 59 and 60, the sliding gears 53 and 54 do not rotate and are engaged with the sliding gears 53 and 54. The left and right annular drums 30 and 31 are in a fixed state, and spin turns cannot be performed.

Thus, reference numeral 69 denotes an inclination sensor for detecting the front and rear and right and left inclinations of the entire body, which is provided at a desired position of the body, and when the inclination detection sensor 69 is `` OFF '', that is, when the body is not inclined more than a predetermined amount.

6, 77 are engaged.

The base of an arm 79 is fixed to the rotating shaft 78, and the distal end of the arm 79 is connected to a solenoid 80 provided at a desired position of the fuselage by a connecting member 81.
(Wire). The solenoid 80 is electrically connected to the tilt sensor 69.

FIG. 3 shows an embodiment in which the connecting member 81 is directly pulled by a manual operation and a manual mechanism 83 for manually switching the spin-turn mechanism is attached, and an end of the connecting member 81 is linked. While being locked to one end of 84, one end of the link 84 and the lower end of the spin lever 82 are connected. The link 84 has an intermediate portion fixed at a desired position on the body, and the solenoid 80 is attached to the other end of the link 84. An inclination sensor 69 is electrically connected to the solenoid 80. Even in this case, the tilt sensor 69 mechanism has priority over the manual mechanism 83, and the solenoid

(Operation) Next, the operation will be described.

The present invention is configured as described above. When the engine 9 is rotated, the rotating shaft 6 is rotated via the gear 10 → the intermediate gear 8 → the input gear 7. Next, the switching gear group 14 is switched, and the small gear 1
6, middle gear 17 or large gear 18
To rotate the center gear 20 via the large gear 18.

When the center gear 20 rotates, the left and right internal teeth 21 and 22 of the center gear 20 rotate.
Since the left and right clutch bodies 23 and 24 mesh with the first and second clutch bodies 23 and 24, the left and right clutch bodies 23 and 24 rotate forward, and the left and right clutch bodies 23 and 24

To run.

Next, the threshing unit 2 of the combine is rotated, and the harvesting unit 3 is rotated.
Is operated, the cut culm is threshed by the threshing unit 2.

Thus, the inclination sensor 69 has a function of detecting the inclination of the field and “ON” when the field is inclined by a predetermined amount or more.
When the field is not tilted more than a predetermined value, the tilt detection sensor 69 is `` off '' when the field is not tilted more than a predetermined value, so that the function is turned off.
The solenoid 80 is not excited.

When the solenoid 80 is not excited, the elasticity of the springs 63, 64 causes the connecting member 81, the arm 79, the rotating shaft 78, the bosses 72, 73,
By moving the shifters 70, 71, the sliding gears 53, 54 are both moved inward, and both of the inner engaging claws 55, 56 are engaged.
Engage both 57 and 58.

Then, the left and right annular drums 30, 31 rotate in the reverse direction to the rotation direction of the center gear 20, and in this state, only one of the left and right clutch bodies 23, 24 is moved outward by the side clutch lever 40. Then, while either one of the left and right clutch bodies 23 and 24 is engaged with the center gear 20, one of the left driving gear 36 and the right driving gear 37 is reversed to perform a spin turn.

Thus, when the field is inclined more than a predetermined amount, or when the field is inclined more than a predetermined amount in the front-rear direction over the ridge of the field,
The tilt sensor 69 is turned “on” and excites the solenoid 80.

When the solenoid 80 is excited, the connecting member 81, the arm 79, the rotating shaft 78, the bosses 72, 73 are opposed to the elasticity of the springs 63, 64.
Move the shifters 70, 71, and move both the sliding gears 53, 54 outward to disengage both the inner engaging claws 55, 56 from the engaging claws 57, 58. Outer engaging claws 61, 62
Are engaged with and fixed to the left and right fixing claws 59 and 60 on the case 5 side.

When the outer engagement claws 61, 62 engage the left and right fixed claws 59, 60,
The sliding gears 53 and 54 do not rotate, the left and right annular drums 30 and 31 meshing with the sliding gears 53 and 54 are in a fixed state, and spin turns cannot be performed.

In the embodiment of FIG. 3, when the spin lever 82 is manually operated, the spin lever 82 directly loosens the connecting member 81, and the spring 63,
When the reversing mechanism A is switched by the resilience of 64 and the side clutch lever 40 is operated in this state, a spin turn can be performed. Even in this case, the tilt sensor 69 has priority over the manual mechanism 83 and the tilt sensor 69 Turns on when it senses a tilt greater than a predetermined value, excites solenoid 80,
The solenoid 80 rotates the link 84 to pull the connecting member 81 to stop the spin turn.

(Effect) Conventionally known, Japanese Patent Application Laid-Open No. 63-125478 discloses a traveling device having a spin turn mechanism, a grain reaper provided in front of the traveling device, and a traveling device provided above the traveling device. In a combine having a threshing unit for threshing grain culms cut by the mowing unit and an inclination sensor for detecting inclination of the body provided in a desired position in the front-rear and left-right directions, the inclination sensor is inclined at a predetermined angle or more. `` On '' when the aircraft is not tilted more than a predetermined angle, `` Off ''
The tilt sensor and the spin turn mechanism, when the tilt sensor is `` off '', spin turn disabled,
A spin-turn control device in a combine in which the tilt-sensor and the spin-turn mechanism are interlocked so as to be able to spin when the tilt-sensor is "on" is described. In this state, when a spin turn is performed, the vehicle body turns significantly and cannot return to the original traveling direction. In a steeply inclined state, a spin turn is performed because it is desired to immediately return to the original direction when the traveling direction turns. Therefore, the slope in the above-mentioned known example is not a large slope because the slope in a flat field is targeted.

However, when the combine moves from field to field, it may cross over high concrete ridges and the ridges of concrete cannot be broken, so the aircraft will tilt heavily back and forth. Also, when working parallel to the ridge, one side rides on the ridge and is in a state just before falling. In such a case, it is inevitable that the aircraft will fall down after a spin turn.

However, the present invention relates to a traveling device 1 provided with a spin-turn mechanism, and a culm cutting section 3 provided on the front side of the traveling device 1.
A threshing unit 2 provided above the traveling device 1 for threshing the stalks mowed by the mowing unit 3 and an inclination sensor 69 for detecting front and rear and left and right inclinations of the machine at a desired position. In the combine, the tilt sensor 69 is set to `` ON '' when the body is tilted more than a predetermined value, and `` OFF '' when the body is not tilted more than a predetermined value. The tilt sensing sensor 69 and the spin turn mechanism are linked so that the spin sensing is possible when the tilt sensing sensor 69 is `` OFF '' and the spin turning is disabled when the tilt sensing sensor 69 is `` ON ''. Since it is a spin-turn control device in the combined combine, when the field is inclined more than a predetermined value, or when the field is inclined more than a predetermined amount in the front-rear direction over the ridge of the field. When the tilt sensor 69 is turned on, the solenoid 80 or a motor is used to fix it so that it does not spin. Because it turns, it has the feature that it is always safe even when the aircraft steeply moves forward, backward, left and right.
