DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in storage of a grain hopper mounted on a truck bed or the like for transporting grains.

[0002]

2. Description of the Related Art When loading a grain hopper onto a tractor carrier, an auxiliary leg with casters is attached so that the front part having a discharge port is located at the rear end of the truck carrier, and the truck moves backward. Then, the grains are loaded from the field, transported to the drying place, and discharged from the discharge port as it is. After retirement,
There is known a method in which auxiliary legs are attached again, loaded and unloaded, and stored using casters as they are. Japanese Utility Model Application Laid-open No. 60-16779 discloses a known technique of an auxiliary leg with casters.
No. 7 is known. In addition, the same applicant has proposed a technology in which a grain hopper disclosed in Japanese Utility Model Application No. Hei 6-64458 is configured to be movable by inverting the grain side.

[0003]

However, Japanese Utility Model Application Laid-Open No. 167797/1985 has a problem that the flat area of the hopper body is required even if the supporting legs are shortened, which occupies a large area of the warehouse. 6-64
No. 458 moves with the narrow side upside down, but there is a troublesome problem that the work of once turning the grain hopper unloaded from the truck or the like to the side is required. In addition, if the conventional grain hopper is simply provided at the center of the long side of the hopper side with respect to the auxiliary legs with casters and horizontally held and vertically supported, it will cause rattling of manufacturing errors and floor Due to the unevenness, the loading side of the grain hopper may fall down and collide during backward movement of the truck bed, or when the side stand is upside down, the center of gravity is at a high position and unstable and danger may be felt. Therefore, it is desired that the height of the horizontal fulcrum of the stand be as low as possible.

The present invention has been made in order to solve the above-mentioned problems.
In a grain hopper with a rectangular shape that can be mounted on a loading platform such as a truck, a drive motor is provided on the front side of the hopper body with the discharge port, and the The horizontal axis of the stand with the casters is supported, and the grain hopper is inverted with this horizontal axis as a fulcrum so that the front side provided with the discharge port and the drive motor is always inclined downward. A grain hopper is proposed, which is configured so as to be capable of being provided with a side inverted fixing means.

[0005]

Since the grain hopper has a discharge port, the front side of which is always inclined downward and supported by a stand with casters so as to rise up, the truck can be mounted smoothly when the truck bed is moved backward. In addition, since a heavy drive motor is provided on the front side with a downwardly inclined discharge port, the center of gravity of the grain hopper is lower than the fixed part fulcrum with respect to the stand, so that the grain hopper swings up and down when moving. Is small. At the same time, the horizontal axis of the stand with casters is deflected to the front side where the drive motor is installed with respect to the center of the long side of the load frame, so when the front side is inverted at the lower end, the support fulcrum is And the driving motor, which is a heavy object, is located at the lowermost end, and the center of gravity is lowered, so that traveling when moving or the like is stable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration will be described with reference to the drawings embodying the present invention. FIG. 1 is a side view embodying the present invention, FIG. 2 is a side view in which an inverted side is inverted, FIG. 3 is a sectional view for explaining a main part of a stand, and FIG. 4 is a perspective view of a main part.

In FIG. 1, the hopper body 3 is loaded,
It is a side view supported by the stand 6 in the horizontal direction for unloading. The hopper body 3 is provided with a transport drive unit 2 and a discharge port 9 in the front. The transport drive unit 2 has a motor, and drives a helical transport body (not shown) arranged at the V-shaped inner bottom of the hopper body 3. 4 is an extension panel,
In this embodiment, it is folded inward when it is stored. The stand 6 is equipped with a pair of front and rear casters 11 at the lower end of an inverted T-shaped column. The upper end of the column 19 is connected to the metal fitting 8.

Reference numeral 10 denotes a horizontal axis provided horizontally on the top of the column 19 of the stand 6. The horizontal axis 10 is configured such that the left side of the left and right packing frames of the grain hopper 1 having a rectangular planar shape and the front side provided with the discharge port 9 are always inclined downward. In this embodiment, the inclination angle (a) is 5 degrees,
The test results were good at 3 to 7 degrees. or,
The horizontal axis 10 of the stand 6 was supported by displacing a distance of 9% to 14% forward with respect to the center of the long side of the grain hopper packing frame. In this embodiment, the length L of the load frame is 10 minutes forward from the center of the long side with respect to the length L of the load frame, that is, 3:
2 was displaced.

FIG. 2 is a side view in which the front surface of the hopper body 3 is turned upside down at the lower end with the horizontal axis 10 of the stand 6 as a fulcrum. The transport drive motor 2 which is a heavy object and a discharge port are provided on the front surface of the hopper body 3, and when inverted, the center of gravity is lowered and stabilized, and the storage area is minimized when stored.

FIG. 3 is a cross-sectional view of a portion to which the stand 6 is attached, and the hopper main body 3 has one side portion 18 forming a V-shaped cross section.
And a boss 7 fixed to the side frame 5 and the side frame 5. Numeral 10 denotes a horizontal axis, the tip of which is fitted to the boss body 7, and the base is formed by a U-shaped metal fitting 8 which stands upright. The upper portion of the column 19 of the stand 6 is fitted in the groove of the metal fitting 8 described above, and is detachably formed by the upper pin 14 and the lower pin 15. Reference numeral 20 denotes a hook plate, and the upper pin 1 is attached to the receiving member 8 of the grain hopper on which the column 19 of the stand 6 is mounted on the truck bed.
The leg is hung when the user presses the side 4 (virtual line) from the side. When the hopper is lifted, insert the lower pin 15.

The horizontal shaft 10 is provided with an engagement hole 13 for fixing to the boss 7 and a stopper hole 12 for preventing the boss 7 from coming off.

FIG. 4 is a perspective view of a support portion of the stand 6. The boss body 7 is provided with vertical and horizontal fixing holes 17 so that the stopper 16 is fitted to the engaging hole 13 of the horizontal shaft 10. It penetrates and sticks. Reference numeral 21 denotes a stopper pin which prevents the horizontal axis 10 from coming off the boss body 7 and is penetrated through the stopper hole 12. The horizontal fixing hole 17 is formed so that the front surface is inclined downward by 5 to 7 degrees.

[0013]

According to the structure of the stand caster described above, the rear part of the grain hopper is always set at a certain angle so that the grain hopper is unloaded from the truck.
Loading can be done smoothly and easily. At the time of inverted storage in the warehouse, the support fulcrum of the stand is low and the center of gravity is low, so that vertical vibration due to movement is small and stable.
