Abstract

PURPOSE:To allow the fixing, release and free mechanism of rotating action to be selected easily by forming a connecting opening part with a sliding plate at the end lower part of a screw conveyor, and providing a connecting device with a connecting metal fitting to hold the sliding plate directly for connection. CONSTITUTION:A sliding plate 5 formed at the end lower part of a screw conveyor 4 at the bottom part of a grain hopper 1 is held by the connecting metal fitting 6 of a conveyor connecting device B. When a lever 9 is pulled to this side by a free lock control means C and rotated in a free position, the conveyor connecting device B is moved into a position parallel to the screw conveyor 4. A lock pin 8 is then dropped into the adjusting hole 11 of a plate frame 19 in the desired position and fixed. Since the grain feeding conveyor connecting device B is thus connected directly to the sliding plate 5, constitution is simplified and made solid. The lock pin 8 is lifted from the adjusting hole 11 to release lock by pulling the lever 9 to this side, so that fixing and release are easily selected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is detachably attached to a connecting opening of a grain hopper which is mounted on a truck bed or the like and is moved so as to directly feed the grain to a spout or the like of a dryer. The present invention relates to the configuration of a connecting device that connects grain transfer conveyors.

[0002]

2. Description of the Related Art Connection devices for grain transfer conveyors in grain hoppers are Japanese Utility Model Publication No. 63-18416 and Japanese Utility Model Publication 3-7.
Known as No. 6822, etc., the connecting device which is the root part of the grain feeding conveyor is configured to be rotatable, and the place where the truck equipped with the grain hopper cannot enter, or the place where the flexible range of the grain feeding conveyor does not meet The degree of freedom is even higher for workability and so on.

[0003]

In the former known technique described above, the connecting device of the grain feeding conveyor protrudes from the side wall of the grain hopper and becomes an obstacle even after the grain feeding conveyor is removed, or the protruding length thereof. There is a problem in that the main body length must be set short in advance. In the latter known page (2) technology, the connection device of the grain feeding conveyor is arranged facing the bottom communication port of the grain hopper, and a separate movable base is installed on the machine frame. The connection device is rotatably arranged. With this configuration, a separate movable base is rotatably installed, resulting in a complicated structure, and since the revolving part is always free, the position of the grain feeding conveyor becomes unstable in a narrow and unreasonable place. There is a problem.

[0004]

[Means for Solving the Problems] In order to solve the above-mentioned problems, a grain body is housed inside, a screw conveyor is arranged at the lowest portion, and a grain feeding kokubeya is attached to and detached from the end portion of this screw conveyor. In a grain hopper provided with a connecting device for freely connecting, a connecting opening having a sliding plate is formed at the lower end of the screw conveyor, and the connecting device is provided with a connecting fitting to perform the sliding operation. A connecting device for a grain feeding conveyor in a grain hopper, which is characterized in that the discs are directly held and connected, and the continuous device is provided with a free lock control means for fixing and releasing sliding rotation.

[0005]

[Operation] Since the connecting device of the grain feeding conveyor is directly connected to the sliding plate provided at the lower end portion of the screw conveyor of the grain hopper, the structure is simple and robust, and the truck is controlled by the free lock control means. A stable grain supply can be achieved by positioning the tip of the grain feeding conveyor at the narrow inlet of the dryer that cannot enter and fixing it at the predetermined position of the connecting device. Further, even when the grain transfer conveyor is removed and moved, if this connecting device is fixed by the free lock means, unnecessary rotation and vibration can be prevented, which is safe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An explanation will be given based on the drawings in which the constitution of the present invention is carried out. FIG. 1 is an external view in which a part is omitted in a perspective view in which the present invention is implemented. Although not shown, the grain hopper 1 is mounted on a carrier such as a truck, and a conveyor connection page (3) device B is provided at the rear part. The conveyor connecting device B is a box-shaped case having an insertion hole 7 for the grain feeding conveyor at the tip, and a motor 3 provided in the rear in one body. C is a free-lock control means for performing fixed-free control in relation to the plate frame 19 hung on the machine frame 12. A shutter lever 2 adjusts the falling amount of the grain inside.

[0007] Fig. 2 is a perspective view of the main part. Fig. 2A shows the bottom of the grain hopper 1, and a connecting opening A is formed at the lower end of the screw conveyor. The connection opening A is configured by horizontally providing a drop opening and a circular brim-shaped sliding plate 5. (B) shows a perspective view of the conveyor connecting device B, which is a box-shaped case having a receiving hole 17 in the upper surface, and the front end insertion port 7 of the grain feeding conveyor D is formed in the front surface. Around the upper part of the receiving hole 17, there is provided a connecting fitting 6 for holding the sliding board 5 described above. Reference numeral 3 denotes a motor, which is integrally assembled in the rear of the box-shaped case of the connection device B in a court.

C is a free lock control means provided on one side of the conveyor connection device B, and when the lever 9 is pulled toward you, the tip of the bracket 23 through the link 10 locks the lock pin 8 and the adjustment hole 11 of the plate frame 19. The connecting device is further raised and unlocked so that the connecting device can rotate with respect to the grain hopper 1. At the time of rotation, the lever 9 may be gripped and rotated as it is.

FIG. 3 is a perspective view of the engaging portion at the base of the grain feeding conveyor port. Reference numeral 15 is a flexible pipe into which the spring conveyor 13 is inserted and one end of which is connected to the engaging shaft 14.

FIG. 4 is a plan view of the conveyor connecting device, which has a receiving hole 17 on the upper surface, and the sliding plate 5 is formed concentrically with the receiving hole. When rotated, it moves to the position indicated by the chain double-dashed line. The lock pin 8 is dropped and fixed to the adjustment hole 11 at a desired position.

Reference numeral 16 denotes an engaging hook provided on the shaft of the motor 3, which engages with the engaging shaft 14 of the grain feeding conveyor D to rotationally drive the spring conveyor 13. Page (4)

FIG. 5 is an explanatory sectional view of the connecting opening A of the grain hopper and the conveyor connecting device B. A grain dropping hole 18 is provided at the bottom end of the screw conveyor, a connecting opening is formed so as to cover the dropping hole 18, and the sliding board 5 is directly connected to the upper surface of the conveyor connecting device B. 24
Guides the grain when the grain feeding conveyor D is engaged by the guide plate.

FIG. 6 is an explanatory view of the free lock control means, in which the lever 9 serves as a handle for rotation of the conveyor connecting device at the same time as fixing and free control. When the lever 9 is pulled toward the front, the lever 9 becomes horizontal, and at this time, the first pin 20 and the second pin 21 serve as fixed points to swing the link 10 and the bracket 23, and the lock pin 8 can be raised.

A leaf spring 22 fixes the lever 9 by pressing the upper surface of the lever 9 and the horizontal side surface indicated by an imaginary line. Therefore, the horizontal position of the imaginary line keeps the rotatable state and is selected as necessary.

[0015]

[Effect] With the above-mentioned structure, the connecting device of the grain conveyor has a simple structure and can fix and release the rotating action.
The free mechanism is convenient because it is easily selected.
