Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine grain tank in which a grain tank is tiltably arranged on a machine base.

[0002]

[Prior Art]

 Conventionally, there is already known a combiner in which a threshing device and a grain tank are provided side by side on a machine platform having a traveling device, and the grain tank can be vertically tilted by a lifting drive device such as a hydraulic cylinder. ..

[0003]

[Problems to be solved by the device]

 In the known combine, the grain tank may gradually rise during traveling due to unevenness in the field scene or fluctuations in the left-right inclination, and in such a case, the grain may leak or the divided portion of the frying cylinder may be divided. Sometimes did not close.

[0004]

[Means for Solving the Problems]

 According to the present invention, a thresher and a grain tank are provided side by side on a machine stand having a traveling device, and the grain tank can be vertically tilted by an elevating and lowering drive device. In the combine that can be inserted from the section and can be separated in the vicinity of the intrusion section, a lower limit detection sensor that detects that the grain tank is at the lower limit of descending and a sensor that detects that the work is in progress are provided, If the lower limit sensor is not detected during work, the lower limit sensor will not be detected even if the grain tank is slightly raised by configuring the lifting drive device to move downward. As a result, the grain tank was lowered to solve the above-mentioned problems.

[0005]

[Action]

 When performing the mowing threshing work, the sensor that detects that the work is in progress is in the detection state, and when the grain tank is at the lower limit of lowering, the lower limit detection sensor is in the detection state. When the airframe vibrates, the grain tank may tilt up and down, and the lower limit detection sensor becomes undetected. Then, the elevating drive device lowers the grain tank for a certain period of time, and when the lower limit detection sensor is in the detection state, the elevating drive device stops, and as a result, the grain tank is always lowered to the predetermined position. Therefore, the grain does not leak and the connection part of the fried cylinder does not close.

【Example】

 The present invention will be described in more detail with reference to the embodiments shown in the drawings. In addition to the threshing device 3 and the grain tank 5 being provided on the machine base 2 having the traveling device 1, the grain tank 5 is provided on the support frame 6. The single-acting hydraulic cylinder 8 which is erected and rotatably supported by the same axis as the discharge spiral 7 at the lower outer side, and which operates by switching the electromagnetic valve, is used to move the grain tank 5 in a substantially horizontal position as a lifting drive device. Tilted between the receiving position and the outwardly tilted grain discharging state, the fried cylinder 10 of the threshing device 3 and the fried spiral shaft installed therein are divided into upper and lower parts at the bottom plate portion of the grain tank 5. The split portion of the fried grain spiral shaft is disengaged by a joint when the grain tank 5 is rotated up and down, and the discharge cylinder connected to the transfer end of the discharge spiral 7 includes a standing cylinder 11 and a movable cylinder 12. Threshing device In front of, it is equipped with a processing device 4 before comprising a cutting device 4a and culms conveying device 4b vertically movably. Reference numeral 9 is an engine, 9a is a radiator, and 14 is a cabin.

A lower limit detection sensor 13 for detecting that the grain tank 5 has descended to the lower limit is attached to the outer side of the upper end of the lower part of the divided part of the fried container 10, and the lower part of the movable cylinder 12 is provided near the base part. , The horizontal turning angle of the movable barrel 12 is 0, that is, the auger storing switch 15 which is turned on when the movable barrel 12 is in the retracted position when viewed from above, and the auger which is turned on when the movable barrel 12 is at the upper limit. An upper limit switch 16 is provided, and a tank raising manual switch 18 and a tank lowering manual switch 19 are provided on the operation panel 17, and these lower limit detection sensor 13, auger upper limit switch 16, auger storing switch 15, and tank raising manual switch are provided. 18 and the operation data for the tank lowering manual switch 19 are input to a controller 20 composed of a microcomputer as shown in FIG. It outputs to the alarm horn 21, the lamp 22, and the solenoid SV ₁ or SV ₂ of the electromagnetic valve associated with the hydraulic cylinder 8 by the turning process.

When the grain tank 5 becomes full or close to it after the mowing and threshing work, the machine is brought close to a transport vehicle parked on the road, and the discharge auger in the storage position in plan view is used. Horizontally swivel the movable cylinder 12 so that its discharge port faces the bed of the carrier (when the movable cylinder 12 is in the complete storage posture in which it is stored in the groove on the upper surface of the grain tank 5, it is rotated upright diagonally). Then, the discharging spiral 7 and the lifting spiral in the discharging auger are driven, and when the shutter on the discharging spiral is opened, the grains in the grain tank 5 are loaded into the carrier bed of the carrier.

At that time, the grain accumulated in the portion of the grain tank 5 along the side of the threshing device 3 is discharged, and then, when the tank raising manual switch 18 is pressed, the control device 20 causes the hydraulic cylinder 8 to move. When the hydraulic cylinder 8 is extended by the output to the tank raising solenoid SV ₁ of the electromagnetic valve that controls the, and the grain tank 5 tilts upward and upward, the grain tank 5 extends to the threshing device 3 of the grain tank 5. When a part of the grain flows down onto the discharge spiral 7 and is discharged, and when the discharge is completed in this way, the tank lowering manual switch 19 is pressed, the electromagnetic valve switches to the lowering side and the hydraulic cylinder 8 lowers and operates. Then, when it is tilted down to a predetermined position, the lower limit detection sensor 13 is turned on, the solenoid valve is neutralized, and at the same time, the divided portion of the fried food container 10 is connected and the horn 21 emits a single sound. 22 is turned on (which may be in either of the horn 21 or lamp), it'll Ri driver knows that grain tank 5 descent has been completed, release the finger without too much press and hold tank manual switch 19 or et al. Further, when performing the mowing and threshing work while the machine is traveling, it is determined that the auger storage switch 15 is ON and the auger upper limit switch 16 is OFF as shown in FIG. The switch that determines that the machine is a threshing clutch switch or a mowing clutch switch may be used), and in this state the machine vibrates due to unevenness in the field, or fluctuations in the left / right tilt, etc. When the lower limit detection sensor 13 of the grain tank 5 that was turned on is changed to off, a timer is set, and the lowering solenoid SV ₂ of the solenoid valve is energized for the time set by this timer and the lowering side is lowered. , The hydraulic cylinder 8 shrinks, the grain tank 5 descends, and when it descends to a predetermined position, the lower limit sensor 13 turns on. Ri, the electromagnetic valve is restored attributed to neutral. That is, if the grain tank 5 rises even a little, it will fall immediately, and the grains will not flow out or the divided parts of the fried cylinder will not be able to be combined.

[Effect of the device]

 According to the present invention, a threshing device 3 and a grain tank 5 are provided on a machine base 2 having a traveling device 1, and the grain tank 5 can be vertically tilted by an elevating drive device. In the combine tank which is inserted from the lower part of the grain tank 5 and is separable in the vicinity of the invasion part, the lower limit detection sensor 13 for detecting that the grain tank 5 is at the lower limit of descending, and working. When the lower limit detection sensor 13 is in a non-detection state during work, the elevating and lowering drive device is configured to move down. When the grain tank 5 rises due to fluctuations in the grain tank 5 and so on, the grain tank 5 descends for the set time and stops at the lower limit position of descending. For 10 tubes Kernels leaks from parts division portion does not become impossible bond.
