JPH0262324A - Uniform distribution hopper for particulate matter - Google Patents

Abstract

PURPOSE:To obtain a hopper which can distribute particulate matter uniformly by providing a pair of screw conveyers extended parallel to each other in the longitudinal direction, the feed directions of which are opposite to each other, in a hopper. CONSTITUTION:Particulate matter is distributed to the right and left by screw conveyers 3a, 3b in a hopper 1. One screw conveyer 3b is adapted to carry the particulate matter to the left, and the other screw conveyer 3a is adapted to carry the particulate matter to the right. When the forward end of a conveyer 2 advances, with the advance, the supply point for particulate matter is moved obliquely. That is, when the supply point is located in the lower right corner, the particulate matter mainly drops on the screw conveyer 3b to sent to the left. When the supply point is located in the upper left corner, the particulate matter mainly drops on the screw conveyer 3a to be sent much to the right. Thus, uniform operation is quickly conducted. When the supply point is located in the center, it uniformly drops on the conveyers 3a, 3b to be sent to both sides. Thus, the particulate matter in the hopper 1 is levelled.

Description

[Detailed Description of the Invention] (1') Industrial Application Field The present invention relates to a hopper that evenly distributes granular materials such as earth and sand, ore, and grains (hereinafter simply referred to as granular materials) to carts, etc. .

(B) Prior Art Conventionally, in order to distribute granular materials into carts, etc., the granular materials are placed on a conveyor, conveyed, and then fed into a hopper. I'm just cutting it out.

However, when a plurality of carts, etc. are connected, it is difficult to cut out the granules evenly onto each cart, etc.

(C) Problems to be Solved by the Invention The problem to be solved by the present invention is to obtain a hopper that can evenly distribute granular materials.

(d) Means for Solving the Problems The hopper for evenly distributing granules of the present invention includes a hopper that receives granules transported on a conveyor, and a conveyor extending at a predetermined angle in the longitudinal direction of the hopper; The above problem is solved by a means consisting of a pair of screw conveyors extending parallel to each other in the longitudinal direction inside the hopper and having opposite feeding directions.

(E) Embodiment The hopper 1 of the present invention will be described with reference to FIGS. 1 and 2. Hopper 1 receives granules conveyed on conveyor 2. When the end of the conveyor 2 moves in the longitudinal direction of the hopper, as shown in FIG.
If the end of the conveyor does not move in the center of the hopper, θ may be 0 (no inclination).

Inside the hopper 1, a pair of screw conveyors 3a extend parallel to each other in the longitudinal direction and have opposite feeding directions.
, 3b are provided. A batcher 4 is provided at the bottom of the hopper 1, and granules with predetermined teeth are cut out onto a cart or the like 5 waiting below the hopper 1.

(f) Function The function of the hopper of the present invention will be explained. As shown in FIG.
It is distributed to the left and right at 3b. For example, one screw conveyor 3b conveys the granules to the left in the drawing, and the other screw conveyor 3a conveys them to the right. conveyor 2
When the tip of the granule advances, the supply point of the granules moves diagonally as it advances. In other words, when the supply point is at the lower right, the granules mainly fall on 3b, so more of them are sent to the left, and when the supply point is at the upper left, the granules mainly fall on 3a, so they are sent to the right. Large quantities are sent, and work is done quickly and evenly. Also, when the supply point is in the center, 3a,
It falls evenly on 3b and is sent to both sides. In this way, the granular material in the hopper 1 is leveled.

By opening and closing the batcher 4, granules are evenly cut out and distributed to each cart 5, etc.

ω) Effects According to the present invention, the granules are evenly leveled within the hopper, making it possible to evenly distribute and cut out the granules.

[Brief explanation of the drawing]

FIG. 1 is a side view of the hopper of the present invention. FIG. 2 is a plan view of FIG. 1. 1: Hopper 2: Conveyor 3a, 3b
: Screw conveyor 4: Batcher 5: Cart, etc.

Claims (1)

[Claims] In the hopper that receives the transported granules, there is a conveyor that extends at a predetermined angle in the longitudinal direction of the hopper, and a pair of screw conveyors that extend parallel to each other in the longitudinal direction inside the hopper and have opposite feeding directions. Hopper for even distribution of granules.
