Description

[Detailed Description of the Invention] [Object of the Invention] "Field of Industrial Application" This invention relates to a hopper for supplying soil.

"Conventional description" A pottery sterilizer is used to burn soil for plant cultivation for the purpose of sterilization.

FIG. 4 is a schematic vertical sectional view of the burned earth sterilizer.

In the drawing, a hopper 41 having a size into which soil is input by human power such as a scoop is provided, and the hopper 41 supplies the soil to a rotating cylindrical drum 42. By rotating the drum 42, the scraping blade provided inside or the drum 42 is arranged so that the outlet side is lowered, so that the soil moves in the direction of the arrow in the drawing. On the other hand, a burner 43 provided on the outlet side of the drum 42 blows a flame against the advancing soil to sterilize the soil. The soil from the outlet of the drum 42 falls on the conveyor 44 and is carried away.

However, machines of the Sjobel Roda Party are generally used, and there is a demand to supply soil to the burned soil sterilizer with a Sjobel loader. The shovel loader cannot be used as it is because the hopper is too small to supply the soil to the burner sterilizer with a shovel loader or the like. Therefore, it is conceivable to install a hopper separately from the burned soil sterilizer.

FIG. 5 is a vertical sectional view of a conventional hopper. A rotary stirring blade 5 and a feed blade 4 are provided in the middle of the inlet 2 and the outlet 3 of the hopper body 1 and on the outlet side. The upper stirring blade 5 prevents the soil from becoming bridging, and the feed blade 4 on the outlet side adjusts the amount of soil discharged from the outlet and is used as a constant amount supply device.

[Problems to be Solved by the Invention] In the above-mentioned hopper, soil may be caught between the feeding blades 4 and the wall of the hopper body 1 on the outlet 3 side, and the soil may be stuck and may not come out. Further, if a stone block in the soil comes in, not only will it be clogged, but also a large force will be applied to the feed vane 4 and the wall surface of the opposing hopper body 1, which may deform the hopper body 1 or the feed blade 4. Furthermore, although the stirring blade 5 is suitable for preventing the soil from bridging, a large impact load is applied when the soil is supplied to the hopper from the inlet 2, so that a shaft much larger than the size required for the stirring purpose is used. It will be necessary. In addition, providing the hopper with two rotary blades complicates the structure.

It is an object of the present invention to provide a hopper that can solve the above-mentioned drawbacks of the conventional hopper and prevent clods and stone blocks from blocking the hopper outlet.

Another object of the present invention is to provide a hopper having a simple structure without stirring blades.

[Constitution of device]

"Means for Solving Problems" This invention is a hopper in which the main body is elastically supported with an inlet at the upper part and an outlet at the lower part, is provided with a vibrating device, and has a feed vane at the outlet of the hopper. A part of the opposing hopper body walls is a movable wall that can be retracted, and the part of the movable wall is supported by a spring member in the forward direction, and the feed vanes have a plurality of radial blade pieces around the horizontal axis. This horizontal shaft is rotatably supported and is connected to a rotary drive source, and a part of the movable wall of the hopper main body facing the feed vane is fed on the side where the vane piece moves downward. A lower wall of the hopper body that faces the blades, and the retractable movable wall is a hopper that is supported so as to widen the outlet opening of the hopper body.

"Operation" If a block of debris that cannot be extruded from the outlet of the hopper body by the force of the feed blade is caught between the feed blade and a part of the wall of the hopper body facing the feed blade, the one facing the feed blade The movable wall of the portion is retracted against the spring force of the spring member supporting the movable wall, and the lumpy debris is passed. Therefore, the soil to be treated does not clog the hopper, and the wing and a part of the wall of the hopper body facing the wing are not overloaded.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. 1 is a longitudinal sectional view, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. 3 is a perspective view. The inverted hopper body 1 in the shape of a truncated pyramid has an inlet 2 at the upper portion and an outlet 3 at the lower portion. The outlet body 3 is supplied with soil. For example, the hopper body 1 is provided with a flange 1a at its upper edge via a vibration-proof rubber 8 by a frame body 7 having four legs 6 so as to be higher than the above-mentioned hopper 41 of the earthmoving machine. It is supported.

A load receiving rod 9 is extended between the opposing walls 1b and 1c of the hopper body 1, and both ends are fixed to the wall. A vibration motor 11 is attached to the outer surface of one wall 1d of the walls 1d and 1e orthogonal to the walls 1b and 1c of the hopper body 1.

A feed blade 4 parallel to the load receiving rod 9 is provided near the outlet 3 of the hopper body 1. The shaft 12 of the feed vane 4 is inserted through the walls 1b and 1c of the hopper body 1 and fixed to the hopper body 1 outside the hopper body 1 by brackets 1f and 1f.
The shaft 12, which is supported by bearings 13 and 13 mounted on, is connected at one end of a shaft 12 to a rotary drive source, for example, a motor 15 mounted on the frame body 7 via a flexible shaft joint 14. Radial blade pieces 4a are circumferentially arranged on the shaft 12 so as to be displaced in the axial direction.

The feed blade 4 rotates in the direction of arrow 16. A part of the lower part of the wall 1e facing the feed vane 4 on the side where the blade piece 4a moves in the downward direction is located above the position of the shaft 12 of the feed vane 4 with respect to the upper and lower sides and the hinge 17 centers the horizontal axis. Is rotatably attached to the movable wall 1g which can be retracted. One end of a rod 21 which is loosely inserted through a hole 19 of a spring receiver 18 fixed to the frame body 7 is pivotally attached to the movable wall 1g, and a nut stopper 22 is screwed into the other end of the spring receiver 18 and locked. ing. A compression coil spring 23 is inserted in the rod 21 between the spring receiver 18 and the movable wall 1g.

Next, the operation will be described. As the vibration motor 11 is energized, the soil in the hopper body 1 is prevented from bridging, and is vibrated to move downward due to gravity. When the motor 15 is energized, the shaft 12 rotates via the flexible shaft coupling 14, and the blade piece 4a rotates in the direction of arrow 16. The soil sent from above by the feeding blade 4 between the feeding blade 4 and the movable wall 1g goes to the outlet 3 and exits from the outlet 3. By making the number of rotations of the feed blade 4 constant, the amount of soil discharged from the outlet becomes constant, and a fixed amount is supplied.

Now, if the lumpy debris in the hopper body 1 comes between the feed blade 4 and the movable wall 1g, if the lumpy debris is broken, it is broken, but it is not broken. Then, due to the rotation of the feed blade 4, the lumpy debris is pressed,
The movable wall 1g is pressed to rotate the movable wall 1g outward of the hopper body 1 around the hinge 17 against the spring force of the compression coil spring 23. Debris can be passed through, and exits from the wide open outlet 3. If the lumpy debris comes out, the compression coil spring 2
Due to the spring force of 3, the movable wall 1g is hinged against the earth pressure inside.
17 toward the inside of the main body 1 of the hopper,
2 is restored by hitting the spring bridge 18.

When soil is introduced from the inlet 2 with a shovel loader, the soil hits the load bearing rod 9 and is prevented from becoming large and large in size. At this time, even when the inside of the hopper body 1 is empty, it is also prevented that the feed blade 4 is directly hit and earth pressure is applied. The load receiving rod 9 also functions to reinforce the sheet metal hopper body 1.

Since the movable wall 1g as described above is provided, the hopper body 1 and the feed blade 4 are not deformed or damaged. Further, since the load receiving rod 9 is provided, the feeding blade is not damaged even if soil is thrown into the hopper body 1 by mechanical force. Since the hopper body 1 and the like are carried on the frame body 7 of the four legs, the stability is good, and there is a flight that can be installed by simply covering it on a clay machine or the like if necessary. Further, it is possible to avoid a situation in which a large hopper is provided on the earth-burning machine and the center of gravity of the earth-burning machine becomes high and stability is impaired.
