[Detailed Description of the Invention] Industrial Application Field The present invention automatically lifts and transports heavy combine bags so that they are tilted to an appropriate height position, thereby saving labor on grain loading devices for various grain dryers. This invention relates to a grain loading device in a grain dryer that can be achieved under the following technology.

Prior Art Conventionally, when carrying out grain drying work by loading harvested grain into a grain dryer, a worker places a heavy combine bag containing the grain into a hopper attached to the bottom of an elevator. Prior to the filing of this application, for example, Japanese Utility Model Publication No. 17004/1988 states that it is necessary to lift and transport grain one by one to a high loading platform, then open the combine bag and at the same time turn it upside down and drop it into the hopper. It has been described and is known.

Problems to be Solved by the Invention By the way, according to the above-mentioned known grain filling means,
Approximately 70 combine bags weighing 30 to 45 kg are collected by workers.
Not only is it necessary to lift and transport each bag individually onto a loading platform at a height of 1.5 cm, but also the combine bags mounted on the loading platform are being held upside down by workers as the amount of waste increases. Since it became essential to discharge the stored grain, workers were forced to do heavy labor during the grain tensioning work, and it was not only difficult to save labor but also to improve the efficiency of the grain tensioning work. An unexpected problem arose.

Therefore, the present invention accomplishes the work of lifting and transporting heavy combine bags one by one and the work of standing the combine bags upside down by mechanical operation, thereby achieving significant labor savings for the operator and further improving the efficiency of grain loading work. The above-mentioned problems are solved by providing a grain loading device in a grain dryer that can be used in a grain dryer.

Means for Solving the Problems Therefore, the technical problem of the present invention is that the work of lifting and transporting a heavy combine bag to the height of the hopper and the work of standing the combine bag upside down after being lifted and transported are all performed by mechanical operation. The purpose is to save labor and improve work efficiency of workers by making them work more accurately. In order to solve this technical problem, the first
The structure of the invention includes a forward and reverse rotation motor, a hollow rotation piece that is integrally provided at the core of a driven pulley that is rotated in the forward and reverse directions by the rotation of the forward and reverse rotation motor, and one side of which is screwed into the hollow rotation piece. , one side of the main body houses an elevating and rotating device consisting of an operating rod whose other end is connected to a lift arm that tilts the tilting support frame downward or upward, and the loading section on the tip side is located near the ground surface. A tilted support frame whose upper end side is rotatably supported on the main body and a chute for feeding grains is attached to the majority of the upper surface side is disposed in a diagonally downwardly inclined shape, and the tilted support frame has a hollow rotary support frame. A grain loading device for a grain dryer, characterized in that an operating rod is raised and lowered by the left and right rotation of a moving piece, and is raised and lowered around a support part so as to be tilted diagonally upward.
Further, the configuration of the second invention includes a rotating disk that is rotated in one direction by a motor, an operating rod that has one end connected to the rotating disk and the other end connected to the inclined support frame, and an operating rod that is provided to protrude from the rotating disk, respectively. Moreover, on one side of the main body, an elevating and rotating device consisting of an upper limit pin and a lower limit pin that alternately opens and closes a limit switch that regulates the upper and lower rotational positions of the inclined support frame is installed.
The loading section on the tip side is located near the ground surface, the upper end side is rotatably supported on the main body, and the tilted support frame, which has a chute for loading grain on the majority of the upper surface, is tilted diagonally downward. The grain dryer is characterized in that the tilted support frame is tilted up and down about the support part as an axis so as to be tilted diagonally upward by an operating rod that is raised and lowered by the rotation of a rotary disk. This is an integrated device.

[Function] Now, when carrying out grain tensioning work efficiently with labor saving using the tensioning device according to the first invention,
First, with the handle 5 pressed down, the main body 1 is moved to the position of the tensioning hopper 30 and set as shown in the first figure.

Next, the combine bag 12 is placed diagonally downward onto the inclined support frame 7 on the mounting section 9 whose lower part is horizontal.
After being mounted so as to be placed on top, the changeover operation switch 26 is operated to start the elevating and rotating device 2 in the normal rotation direction so that the tilting support frame 7 is tilted diagonally upward. Then, the driven pulley 19 and the hollow rotating piece 20 are rotated in the normal rotation direction by the normal rotation of the forward/reverse rotation motor 17, and the operating rod 22 is extended diagonally upward by the rotation of the hollow rotating piece 20. .

With this extending operation of the operating rod 2, the lift arm 13 is rotated upwardly in the clockwise direction in FIG.
The combine bag 12 is rotated upward in the clockwise direction with the combine bag 12 mounted on the axis 1. And the inclined support frame 7
When the upper limit switch 28 is opened in a predetermined diagonally upwardly inclined state, the operation of the lifting and rotating device 2 is automatically stopped. In this stopped state, the lower end of the chute 15 faces the tensioning hopper 30 because the inclined support frame 7 is inclined obliquely upward.

Therefore, when the combine bag 12 is opened,
The stored grain automatically falls into the loading hopper 30 through the chute 15, and is loaded into a grain dryer (not shown) by the operation of the elevator 29. As described above, when the grain filling work in one combine harvester bag 12 is completed, if the changeover operation switch 26 is operated again, the elevating and rotating device 2 starts operating, and the forward and reverse rotation motor 17 is rotated in the reverse direction. and rotate the operating rod 22 downward. Due to this downward rotation of the operating rod 22, the lift arm 13 also rotates counterclockwise in FIG. It rotates downward in the clockwise direction to reach a predetermined diagonally downward tilted state, opens the lower limit switch 27, stops the operation of the elevating and rotating device 2, and prepares for the next tensioning operation.

By repeating the above-mentioned operations, even with a large amount of grain, it is possible to efficiently stake out a large amount of grain while saving labor. Further, in the first invention device, since the inclined support frame 7 and the lift arm 13 are pivotally connected at separate positions, the lift arm 1
3, even if an object or person is placed under the inclined support frame 7 and gets caught between it and the frame 3, only the lift arm 13 will rotate downward, and the inclined support frame 7 will When the lift arm 13 stops at the spot without being supported by an obstacle and does not rotate downward, the lower limit switch 2 is activated.
7 is opened to stop the operation of the lifting and rotating device 2, thereby preventing danger.

Further, in the second invention device, when the lower limit pin 40 is engaged with the limit switch 41, if the manual operation switch 42 is pressed and operated, the motor 31 is activated.
starts operating, and the rotating disk 3 is powered by the motor 31.
3 to one side, and the operating rods 22 are sequentially raised to upwardly rotate the inclined support frame 7 which was in the state shown in FIG. Since the motor 31 is stopped at the position where the limit switch 41 is opened, the inclined support frame 7 is stopped in the diagonally upwardly inclined state, and the grain is automatically opened by opening the combine bag 12 mounted on the inclined support frame 7. It is possible to perform stake-out work by dropping the stake into the stake-out hopper 30. Also, in the above state, the manual operation switch 4
2 is pressed again, the motor 31 starts operating again and rotates the rotary disk 33 in one direction. As the rotary disk 33 rotates, the operating rod 22 sequentially descends and moves the inclined support frame 7 to the position shown in FIG. The tilt support frame 7 is rotated diagonally downward so as to be in the state shown in FIG. stop it,
Prepare for the next loading work of the combine bag 12.

In addition, even in the case of the above-mentioned crank type lifting/lowering rotating device 2, when the tilting support frame 7 is rotated downward, the tilting support frame 7
Even if a person or object is placed underneath and gets caught between the frame 3 and the frame 3, the operating rod 22 and the fitting tube 38 are connected in a plug-in manner, so the inclined support frame 7
The actuating rod 22 is configured to stop in place without being supported by an obstacle and rotating downward, and only the actuating rod 22 descends while coming out of the fitting tube 38 to prevent danger.
