Description

[Detailed description of the invention] [Industrial application field] This invention stores grains harvested by a combine harvester or the like in a field, transports them to a farmer's workplace using a transport vehicle, and transfers them to other grain processing containers. Relating to improvements in grain storage equipment for transfer.

[Prior art and its issues] Conventionally, the transport vehicle for storing grain harvested by a combine harvester in the field and transporting it to the farmer's workplace has been to use a container that can be tilted manually on the platform of an ordinary small truck. Was. This container transmits rotation by a manual handle to an endless wire stretched horizontally through a speed reduction mechanism, and by moving this wire back and forth, the container, whose rear end is pivoted on a frame, is tilted backwards, and the opening is opened. It was opened and the stored grain was transferred to another processing container. In this way, manually moving the wire through a speed reduction mechanism has the disadvantage that the number of rotations is extremely high, which places a heavy burden on the operator, and also requires a lot of time. Mechanisms that allow wires to support significant weight also present design challenges.

The present invention was devised in view of the above circumstances, and aims to provide a grain storage device that uses a pulley block to tilt containers without requiring any manual labor, and that is also efficient in transfer operations. It is something.

[Means for Solving the Problems] The structure of the present invention that solves the problems of the prior art is such that the rear end of the cubic grain container is pivotally supported on the left and right sides of the lower rear end of the grain container. In a grain storage device in which an opening with a door that automatically opens when the grain container is tilted downward is formed in the rear wall,
A round bar is pivoted between the front ends of the underframe, and the lower end of the column that can be tilted in the front and back direction is supported by this round bar.Furthermore, a fixed pulley 12a constituting the pulley block 12 is attached to the rear surface of the upper end of the column. In addition, a floating pulley 1 which always corresponds to the same vertical plane as the fixed pulley 12a and which constitutes the above-mentioned pulley block 12 is provided.
2b is attached to the front lower part of the grain container, and a winding drum driven by a driving means such as a motor is provided on one side of the front face of the column, and a wire having one end fixed to the column is connected to the fixed pulley 12.
(a) A plurality of wires are wound around the floating pulley 12b, and the other end of the wire is connected to the winding drum.

This underframe 8 is placed, for example, on the loading platform (not shown) of a transport vehicle such as a truck, and the grain container 1 is placed within this underframe 8, as is clear from the figure. Then, on the left and right ends of the rear surface of the base frame 1a of this grain container 1, this base frame 1a is attached.

Although not particularly shown, there is a wire winding part,
It is natural to provide safety devices such as a stop switch and a rotation stop clutch for the winding drum.

Furthermore, the underframe 8 and grain container 1 can be separated, and after first mounting the underframe 8 on the loading platform, the grain container 1 is set between the steel rods 8a, and the rear ends of both steel rods 8a are removed. The base frame 1a of the shaft hole 8c of the underframe 8
After inserting the fulcrum shaft 9 provided in the holder, both steel rods 8a are returned to their original positions, and the dowel pin 10 is driven in to complete the assembly.Disassembly can be performed by reversing the above procedure.

[Explanation of action] The operation of the above embodiment will be explained.

The grain storage device having the structure of the present invention is mounted on the loading platform of a transport vehicle such as a truck, and the grain container is
is transported to the field empty. In a farm field, for example, rice is being harvested using a combine harvester, and the harvested and threshed grain is temporarily stored in the combine itself, but it is also stored on the loading platform of a transport vehicle waiting near the field. The grains are transferred to grain container 1 located at This transport vehicle then returns to the farmer's workplace and transfers the grain to another processing container.

Then, when the transport vehicle returns to the work site, the driver operates the vehicle to position the rear end of the vehicle body, specifically, the rear surface of the grain container 1, so as to fit into another processing container that receives the grains. Next, the motor 13 is driven to wind the wire 16 onto the winding drum 15.
Due to the principle of the pulley block 12, the floating pulley 12b
is pulled up toward the fixed pulley 12a, and the grain container 1 tilts about the fulcrum shaft 9 as shown by the imaginary line in FIG. Then, the unlocked door 3 is automatically opened as shown by the phantom line, and the grains are transferred to the processing container from which they were released.

At this time, since the column 11 is simply mounted on the round bar 8b of the underframe 8 via the downward U-shaped support metal fitting 11a provided at the lower end of the column, the column 11
is tilted in the direction of the grain container 1 as shown by the imaginary line, and the centers of the fixed pulley 12a and the floating pulley 12b constituting the pulley block 12 are always on the same vertical plane, so that the tensile force by the pulley block 12 always acts effectively. At the same time, since the moment of force on the support column 11 is small, the strength of the support column 11 is not required to be very strong.

When the grain discharge is completed, the drive of the motor 13 is stopped and the rotation stop clutch is released, and all the tilted members return to their old positions. Then, after locking door 3 again, the transport vehicle is operated to the field again.
Repeat similar tasks.

[Effects of the Invention] As described above, according to the configuration of the present invention, the following effects can be obtained.

(a) It goes without saying that the grain collected in the field can be transported to the workplace and the stored grain can be transferred to another processing container by dumping the grain container. (b) The dumping operation of the grain container can be A pulley block 12 with a plurality of wraparound structures consisting of a fixed pulley 12a and a floating pulley 12b provided between the upper end of the rear surface of the column attached to the frame and the lower front surface of the grain container.
This allows the grain container to be dumped with several times the pulling force and one-fold the pulling speed.In addition, since the support can be tilted relative to the underframe, the grain container can be dumped backwards. Following the tilting movement, the column tilts toward the grain container, and the centers of the fixed pulley 12a and the floating pulley 12b constituting the pulley block 12 are always on the same vertical plane.
The tensile force exerted by the pulley block always acts effectively, and the moment of force applied to the support column can be reduced. Therefore, the support column strength is not required so much, and the structure can be simplified.
