Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a grain discharge device for a combine harvester having a grain tank.

(b) Prior art Conventionally, a threshing device and a grain tank were provided on the machine base of a combine, and a discharge auger was attached to the grain tank for lifting and discharging the grains onto the loading platform of a transport vehicle. A combine harvester that is not capable of raising and lowering and also folds the upper folding part into two was developed in 1972.
This is already known from Publication No.-80850.

(c) Problems to be Solved by the Invention In the grain discharge device of the known combine harvester, the lower part of the lodging part of the discharge auger is placed on the inclined part of the side part of the threshing device, and The machine body protrudes rearward from the threshing machine and runs along the rear surface of the machine, and as the machine body repeats rolling and pitching during operation, the support of the discharge auger is unstable, and the upper side protrudes backward from the machine body, causing the machine body to repeatedly roll and pitch during operation. It was dangerous when moving around, and required a large space to store.

In addition, the bottom of the grain tank is formed in a V-shape so that the middle part of the width is at the bottom, considering the angle of repose of the grains and the storage capacity, so the transfer spiral for discharge is placed near the center of the bottom of the grain tank. Therefore, in the known threshing discharge device, the upper part of the upright part of the discharge auger is bent diagonally upward and outward, and a receding part is provided at the upper end. They were connected and bent backwards, and the rear part was further bent to follow the rear surface of the threshing device and grain tank, but if the upper part of the raised part was bent diagonally, the machining of the cylinder itself was extremely troublesome. In addition to being expensive, the long and heavy lodging section was suspended from the outside of the fuselage, making it unstable and causing damage and noise due to the vibration of the fuselage.

(d) Means for solving the problem The present invention has a threshing device 1 mounted on one side of a machine base having a traveling device 2, and a grain tank 6 on the other side and a driver's seat 5 in the front thereof. Then, the Glentank 6
A discharge auger 10 for lifting and carrying out the grains inside is divided into an upright part 10a and a lodging part 10b which is pivotally supported on the upper part so that it can be folded down and whose distal end part is connected to the base end part so as to be bendable and extensible. In this combine harvester, the upright part 10a of the discharge auger is provided at one end of the grain tank 6 in the front and back direction.
0 to such an extent that at least the proximal end side of the grain tank 6 is tilted sideways toward the other end side,
The lodging portion 10b is in a lodging posture, and its tip side portion is folded back toward one end on the threshing device 1 so that it forms a V-shape in plan view with the proximal portion, and is arranged so that it fits within the projection plane of the machine body. The above-mentioned problem is solved by providing at least two saddles that separately support the proximal portion and the distal portion, and attaching the operating rod 14 to the distal portion of the lodging portion 10b. did.

(E) Function When discharging the grains in the grain tank, the entire discharge auger is extended in a straight line, and in that state it is tilted toward the transport vehicle to lift and discharge the grains, allowing it to be driven on the road, stored, etc. When storing the auger, after laying down the entire lodging part toward the other end, fold the upper end part back to one end and place it on the threshing device, then fold the upper end part and the base end part. It is supported by separate saddles to form a V-shape in plan view and is housed within the projection plane of the fuselage.

(F) Example An example of the present invention will be explained with reference to the drawings.
1 is a threshing device mounted on one side of a machine base 3 having a traveling device 2, and on the other side of the machine base 3, an operation panel 4, a driver's seat 5, and a grain tank 6 are arranged in order from the front. However, a reaping device 7 and a grain culm conveying device 8 are installed in front of the machine stand 3.

At the bottom of the grain tank 6, there is provided a forward and backward transfer spiral (not shown), and at one end of the grain tank 6, which is the end of the transfer, there is a hydraulic cylinder 9 whose lower end is centered around the front and rear axis. The discharge auger 10 is pivoted so that it can take an upright position or an inclined position as shown in FIG. The base side is connected to the upright part 10a, and the tip side is connected by a hinge 11 having a horizontal axis that extends to the lowered part 10b.
The lowered portion 10b is lowered toward the other end of the grain tank 6 by the hydraulic cylinder 12.

In addition, the above-mentioned lodging portion 10b is further divided into a proximal end portion and a distal end portion at the midpoint, and the divided portions are connected to each other so as to be bendable and extensible by a pivot shaft 13 which is directed upward on the side opposite to the driver's seat 5 in the lodging posture. It has been done.

Furthermore, the base of the operating rod 14 is rotatably attached to the tip side of the lodging portion 10b, and when the discharge auger 10 is arranged in a straight line to discharge the grains, it is as shown in FIG. The engaging protrusion 15 is fitted into a clamp 16 made of an elastic material to maintain the joined state, and at that time, the operating rod 14
is fitted into another clamp 17 and fixed.

Reference numeral 18 denotes a saddle that rotates upward to support the proximal portion of the folded portion 10b from the midway bending portion;
Reference numeral 9 denotes a sideways saddle with an opening on the side opposite to the driver's seat 5 so as to support the distal end portion, and the proximal end portion and the distal end portion of the lodging portion 10b rest on the grain tank 6 and the threshing device 1. It has a V-shape when viewed from above and is housed within the projection plane of the fuselage. 20
is a locking metal with a locking hole 20a protruding from the middle portion of the operating rod 14, and is secured by fitting into a pin 22 provided on a receiver 21 fixed to the folding portion 10b.

When the above-mentioned combine harvester is driven on the road or stored, the discharge auger 10 crosses diagonally from the rear of the driver's seat 5 side to the middle of the front of the threshing device 1, as shown by the solid line in FIG. The pivot 13 is located above the supply port of the threshing device, and the front end side is folded back around the pivot 13 on the opposite side of the driver's seat 5 to the saddle 1 on the threshing device 1.
It is on board 8.

In addition, when performing reaping and threshing work, the control vehicle removes the operating rod 14 from the pin 22 from the driver's seat 5 and pushes it outward, and the distal end of the discharge auger 10 rotates very easily around the pivot 13. As shown by the chain line, the collapsed portion 10b becomes a straight line, and the engaging protrusion 15 fits into the clamp 16 to maintain the straight line. After that, when the operating rod 14 is fitted to the clamp 17, the discharge auger 10 will be in a state diagonally across the body, and the discharge port will protrude outward to the extent that it does not get in the way even when the reaping device 7 is raised. In this state, the machine is run, and the grain culm harvested by the reaping device 7 is supplied to the threshing device 1 by the grain culm conveying device 8, and the sorted grains are filled into the grain tank 6 by the grain lifting cylinder 23. Ru.

At this time, when the grain tank 6 is filled with grain, the weight of the grain tank 6 increases and the center of gravity tends to move to the rear of the driver's seat 5 side. By countering this, you can maintain balance in the front, back, left, and right directions.

When the grain tank 6 becomes full by continuing such reaping and threshing work, the machine is brought close to a transport vehicle such as a truck 24 parked on the road, and the lodging section 1 is moved by activating the hydraulic cylinder 12.
0b is raised to be in line with the rising part 10a, and then the entire discharge auger 10 is moved by the lower hydraulic cylinder 9 to the track 24 as shown in FIG.
The discharge port at the upper end faces the loading platform of the truck 24.

At this time, the transfer spirals in the discharge auger 10 are connected at the divided portions by respective spigot joints, so that the grains in the grain tank 6 are thrown into the loading platform of the truck 24.

At that time, the discharge auger 1, which is in an inclined position,
Since the pivot 13 that connects the divided parts of the collapsed portion 10b of 0 is located on the upper surface side and supports it, a stable connected state can be maintained even if the locking force of the clamp 16 on the lower surface side is weak.

Once the grains have been discharged, the entire discharge auger 10 is erected in the reverse order to that described above, and the lodging portion 10a is then laid down toward the front side, that is, toward the other end, as shown in FIG. As shown by the chain line, the tip end portion is further bent toward one end to form a V-shape in plan view as shown by the solid line, and is housed on the upper part of the threshing device 1 on the body projection surface.

(G) Effects of the Invention As described above, the present invention has the threshing device 1 mounted on one side of the machine base having the traveling device 2, the grain tank 6 on the other side, and the driver's seat 5 disposed in the front thereof. , a discharge auger 10 for lifting and carrying out the grains in the grain tank 6 is pivotally supported on the upright part 10a so that it can fall down, and the distal end part is connected to the base end part so as to be bendable and extensible. In the combine harvester, in which the rising part 10a of the discharge auger is provided at one end of the grain tank 6 in the front-rear direction, at least the proximal end portion of the lowering part 10 is located above the grain tank 6. The lodging portion 10b is raised to such an extent that it falls sideways toward the end, and the tip side portion of the lodging portion 10b is folded back toward one end on the threshing device 1 in the lodging posture, forming a V-shape in plan view with the proximal portion. At least two saddles are provided so as to fit within the projection plane of the fuselage, and separately support the proximal portion and the distal portion, and the distal portion of the lodging portion 10b is provided with at least two saddles that can be operated on the distal portion of the lodging portion 10b. Since the rod 14 is attached, the lodging part 10b does not protrude outside the aircraft, allowing safe operation without causing an obstacle when driving on the road. It can be easily aligned and stored in a narrow space.

Furthermore, the base end portion of the lodging portion 10b of the discharge auger 10 is laid down from one end side to the other end side in the front-back direction of the grain tank 6, and the tip side portion is folded back in the opposite direction and placed on the threshing device 1, as seen in plan view. Because it is V-shaped, the center of gravity of the aircraft does not move backwards unlike when the upper end is placed along the rear of the aircraft, and it is possible to run stably while preventing the aircraft from increasing its head.

In addition, the long and heavy lodging section 10b can be reliably supported at its proximal end and distal end separately and at two separate locations, thereby preventing noise and damage caused by vibrations of the aircraft body. can.
