JPH08623B2 - Evenly distributed hopper for granules - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a hopper that evenly distributes granular materials such as earth and sand, ores, and grains (hereinafter simply referred to as granular materials) to a trolley or the like.

(B) Conventional technology Conventionally, in order to distribute granular materials to a dolly, etc., the granular material is placed on a conveyor, conveyed, once put into a hopper, and then cut out by a predetermined amount to a dolly waiting below the hopper. ing.

However, when multiple vehicles are connected,
It is difficult to evenly cut out the granular material on each carriage or the like.

(C) Problem to be Solved by the Invention A problem to be solved by the present invention is to obtain a hopper capable of evenly distributing granular materials.

(D) Means for Solving the Problem A hopper for evenly distributing granular material according to the present invention is a hopper that receives conveyed granular material and has a bottom portion provided with a plurality of batchers along the longitudinal direction. It extends upward at a predetermined angle in the longitudinal direction of the hopper and advances in the longitudinal direction.
The above problem is solved by means of a retractable conveyor and a pair of fully open type screw conveyors that extend in the longitudinal direction parallel to each other in the hopper and have feed directions opposite to each other.

(E) Embodiment A hopper 1 of the present invention will be described with reference to FIGS. 1 and 2. The hopper 1 receives the granular material conveyed on the conveyor 2. When the end of the conveyor moves in the longitudinal direction of the hopper, the conveyor 2 extends above the hopper 1 at a predetermined angle θ in the longitudinal direction of the hopper 1, as shown in FIG. If the center of the hopper does not move, θ = 0 (no tilt) is sufficient.

Inside the hopper 1, a pair of screw conveyors 3 extending parallel to each other in the longitudinal direction and having feed directions opposite to each other.
a and 3b are provided. At the bottom of the hopper 1 is a batcher 4
Is provided, and a predetermined amount of granular material is cut out on the trolley 5 or the like waiting below the hopper 1.

(F) Action The action of the hopper of the present invention will be described. As shown in FIG. 2, the granular materials are screw conveyors 3 a, 3 in the hopper 1.
It is distributed left and right with b. Since the screw conveyors 3a and 3b are of the general open type in which fins are spirally wound around the rotating shaft, they also allow natural fall while transporting the granular material forward. For example, one screw conveyor 3b
Allows the granular material to drop naturally while carrying it to the left in the drawing,
The other screw conveyor 3a is naturally dropped while being transported to the right.

Since the conveyor 2 is inclined with respect to the longitudinal direction of the hopper 1, when the leading end of the conveyor 2 moves forward and backward, the supply point of the granular material moves diagonally. For example, in FIG. 2, when the feed point is at the lower right, the particulate matter mainly falls on 3b, so a large amount of particles are sent from the right side to the left side, and when the feed point is at the upper left corner, the particulate matter is mainly present. Since it falls on 3a, it is sent from left to right. Also, when the supply point is in the center, it falls evenly on 3a and 3b and is sent to both sides. When the supply point is at an intermediate point other than the above, the particulate matter is proportionally distributed on 3a and 3b according to the position.

In this way, by adjusting the position of the tip of the conveyor 2, that is, the position of the supply point, the leveling operation of the granular material in the hopper 1 can be performed quickly.

By opening and closing the batcher 4, the granular material is evenly cut out and distributed to each dolly 5 or the like.

(G) Effect According to the present invention, since the granular material is evenly distributed in the hopper, it is possible to evenly distribute and cut out the granular material.

Claims (1)

[Claims] 1. A hopper that receives conveyed particulate matter and has a bottom provided with a plurality of batchers along the longitudinal direction, and extends at a predetermined angle in the longitudinal direction of the hopper above the hopper and the longitudinal direction. An upper conveyor that can be moved forward and backward, and a pair of fully open lower screw conveyors that extend in the longitudinal direction parallel to each other in the hopper and have feed directions opposite to each other. The feed point is on the feed start end of one of the pair of lower screw conveyors when advanced to the maximum, and the feed point is the feed of the other one of the lower screw conveyor when the feed point at the tip is retracted to the maximum. When it is on the starting end and the feed point at the tip is approximately in the center of the forward / backward position, the feed point is approximately above the center of both of the lower screw conveyors. Even distribution hopper the granulate is passed said angle as was characterized in that it is set.
