Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a paddy carry-out mechanism of a combine.

(B) Conventional Technology It has been conventionally known that, in combine harvesters, a vertical carry-out auger and a carry-out auger tube are provided to discharge the paddy in the Glen tank to the bed of the truck.

(C) Problems to be solved by the invention However, in the prior art, in order to uniformly load the cargo into the loading platform of the truck, the carry-out auger cylinder itself is rotated or the combine is moved back and forth to carry out the carry-out. The only option was to move the tip of the auger cylinder.

The present invention solves this problem by rotating the chute portion at the tip of the carry-out auger cylinder back and forth.

(D) Means for Solving Problems The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

A vertical carry-out auger 3 is arranged to discharge the paddy stored in the grain tank T of the combine harvester, and a carry-out auger cylinder that is horizontally rotatable around the vertical carry-out auger 3 at the upper part of the vertical carry-out auger 3. When the paddles 2 are connected and a certain amount of paddy is accumulated, the vertical discharge auger 3 and the discharge auger cylinder 2 are driven to be loaded into the truck stopped on the ridge, and the chute at the tip of the discharge auger cylinder 2 is rotated. The chutes 23, 25 are provided, and the rotating chutes 23, 25 are closer to and farther from the vertical carry-out auger 3 by the operator sitting on the seat 18 remotely operating the motor pinion device 26 or the projecting cylinder device 9. The rotation can be adjusted in any direction.

(E) Embodiment The problems to be solved and the means for solving the present invention are as described above. Next, the structure of the embodiment shown in the accompanying drawings will be described.

FIG. 1 is a plan view of a combine, FIG. 2 is a front sectional view showing a sliding support portion between a chassis frame E and a track frame F, and FIG. 3 is a control block circuit diagram showing a left / right balance automatic control mechanism, 4 is a perspective view of the track frame F and the crawlers 1L, 1R, FIG. 5 is an enlarged side view of the sliding roller 14, and FIG. 6 is an obstacle detection sensor 20, 19 provided on the carry-out auger cylinder 2. It is a control circuit diagram.

In FIG. 1, the overall structure of the combine will be described.

The crawlers 1L and 1R drive the paddy field and the road, and the grain culms are harvested and transported by the weeding / raising / harvesting device provided at the front end of the machine, and then transported to the threshing device D. The threshed rice after threshing by the threshing device D is conveyed to the inside of the Glen tank T by the charging auger 39 and stored inside the Glen tank T. Mowing is performed in the state of being stored inside the Glen tank T, and when a certain amount or more is accumulated, the carry-out auger cylinder 2 is driven to reload the truck to a ridge road.

Then, a cutter, a straw bundling device, or the like as the straw processing device 15 is provided at the rear part of the threshing device D, and a clogging cleaning cover 16 that is opened when the straw processing device 15 is clogged is provided. There is. When the carry-out auger tube 2 is rotated with the clogging cleaning cover 16 left open,
Since the carry-out auger tube 2 and the clogging cleaning cover 16 interfere with each other and either of them is damaged, the obstacle detection sensor 19 for detecting the open state of the clogging cleaning cover 16 is used as the carry-out auger tube 2
It is provided in.

In addition, if the carry-out auger cylinder 2 is rotated with the operator 17 sitting on the seat 18, the operator 17 will suffer a personal injury. An obstacle detection sensor 20 is arranged at a position corresponding to the operator 17 of No. 2.

The signals transmitted from the obstacle detection sensors 19 and 20 are
As shown in FIG. 6, signal processing is performed via the amplifier 21 and the controller 22, and the control signal is transmitted to the rotation drive motor M of the carry-out auger cylinder 2. Even when the carry-out auger cylinder 2 is rotated by the rotation drive motor M, if the obstacle detection sensors 19 and 20 detect an obstacle, the drive of the rotation drive motor M is stopped, It prevents the damage to the aircraft and the occurrence of personal injury.

Then, on the upper surface of the track frame F, the sliding roller
The chassis frame E is supported so as to be slidable from side to side via 14a, 14b, and 14c.

The construction of the sliding roller 14 is described in detail in FIG.

That is, the sliding roller 14 is a lower sliding roller 14a, an upper sliding roller 14c, and a side manual roller 14b.
Supported by 14. As shown in FIG. 4, the sliding roller 14 is in contact with the upper and side surfaces of the track frame F.

In this state, the chassis frame E slides left and right by the left and right sliding cylinders 11 and 12 shown in FIG. The left and right sliding cylinders 11 and 12 receive a signal from the Glen tank amount sensor 13 provided in the Glen tank T as a controller B.
The solenoid 10 is operated after being transmitted to and compared with. The solenoid 10 operates the left and right sliding cylinders 11 and 12 to slide the chassis frame E left and right.

By the above operation, the chassis frame E is slid with respect to the track frame F to adjust the running balance of the machine body.

FIG. 7 is a perspective view of the tip chute adjusting mechanism of the carry-out auger cylinder 2, FIG. 8 is a perspective view when the chute is adjusted near, and FIG. 9 is a perspective view when the chute is adjusted far. .

A rack 8 is engraved on the tip of the carry-out auger cylinder 2,
A motor pinion device 26 is meshed with the rack 8.
The motor pinion device 26 can be remotely controlled by the operator 17 of the seat 18. Then, the rotary chutes 23, 25 can be adjusted to a far distance and a near distance by the remote control.

A sliding cylinder 27 is fixed by the motor pinion device 26, and an extension cylinder device 9 is additionally provided below the sliding cylinder 27.

The extension cylinder device 9 extends at the front and rear ends of the movement of the motor pinion device 26.

Similarly, FIG. 11 is a side sectional view of the unloading auger cylinder 2 in a contracted state, and FIG. 12 is a front sectional view of the same.

The bevel gear boxes 36, 30 and the chain case 31 are provided at the upper end of the vertical carry-out auger 3, and the bevel gear boxes 36, 30 and the chain case 31 allow the vertical carry-out auger 3 to move.
The rotation of is changed to the rotation of the carry-out auger cylinder 2.

The auger shaft of the carry-out auger cylinder 2 is the cylinder shaft 32 and the spline shaft.
It is composed of 33, and sliding adjustment is possible at this portion. Further, even when the carry-out auger tube 2 is stretched and adjusted farther and closer to the vertical carry-out auger 3, the discharge of the vertical carry-out auger 3 is performed so that the paddy can be inherited from the vertical carry-out auger 3 to the carry-out auger tube 2. With respect to the hole 34, the receiving hole of the carry-out auger cylinder 2 is formed as a long hole 35.

6 is a crack and pinion mechanism for expanding and contracting the carry-out auger cylinder 2.
