Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hopper gate that temporarily stores powder, granules, etc. and allows them to flow down to a belt conveyor.

[Prior Art] A hopper, which temporarily stores grains such as wheat and soybeans and allows them to flow down onto a belt conveyor when necessary, has a conical or pyramidal shape extending below the main body 11, as shown in FIGS. 6 and 7. A hopper cutting device 20 as a hopper gate is provided at the outlet 13 so that the lower end of the inclined portion 12 serves as an outlet 13 of a required diameter.

An example of the hopper cutting device 20 that includes a gate body, an opening/closing cylinder, etc. is as follows.
There is one in which the outlet 13 is opened and closed by horizontally moving a flat gate body 21 having a width and length larger than the width and length of the outlet 13 using an opening/closing cylinder 41. , support arms 4 upward from the four corners of the flat gate body 21.
5, a wheel 47 is provided at the upper end of the support arm 45, and the wheel 47 is mounted on parallel and horizontal rails 17 provided above both ends of the support part 15 that protrudes from the lower end of the hopper slope part 12 to the left and right. The opening/closing cylinder 4 is placed so that the gate body 21 can move smoothly in the horizontal direction, and a piston rod 43 is connected to one end of the gate body 21.
1 is provided approximately horizontally.

[Problems to be solved by the invention] When powder or granules such as grains are allowed to flow down onto a belt conveyor using the hopper, when the belt conveyor stops due to an accident such as a power outage, the products in the hopper will flow out from the outlet. It may continue to flow down, overflowing from the top of the belt conveyor, and spilling to the left and right sides of the belt conveyor.

Further, since the opening/closing cylinder is provided horizontally, the opening/closing cylinder is long because it requires a required stroke length, and it also has the disadvantage of requiring a large space for the cutting device.

[Means for solving the problem] The present invention provides one support arm attached to a wheel on each side of the gate body, and connects the rear end of the gate body and the hopper slope with a link rod. Further, the rear end of the opening/closing cylinder is attached to the hopper inclined part, and flat skirt parts are made to protrude vertically from the tip of the gate body obliquely upward on the left and right sides of the gate body.

[Function] Since the present invention supports the gate body by a support arm having one wheel on each left and right and a link rod provided at the rear end of the gate body, the rear end of the gate body can be moved while horizontally moving the gate body. The gate can be opened and closed by rotating the gate upward, and the skirt section provided diagonally upward from the tip of the gate body is located above the gate body when the gate body is closed. When the gate body is opened, it becomes lower than the gate body and covers the left and right sides of the outlet.

[Example] As shown in FIG. 1, the hopper cutting device 20 according to the present invention includes a flat gate portion 25 that is slightly wider than the width of the outlet 13 of the hopper 10, and the gate portion 2.
Lateral support 31 and front-back support 3 that reinforce 5
2 to form a gate body 21, and a horizontal support 31
is made to protrude from the gate portion 25 in the left and right horizontal direction,
A support arm 45 of an appropriate length is provided vertically upward from both ends of the horizontal support 31, and a wheel 47 whose rotation axis is in the horizontal direction is provided inside near the upper end of the support arm 45.

Further, a support part 15 is horizontally projected from the lower end of the hopper inclined part 12 to the left and right, and rails 17 are provided on the upper surface of both left and right ends of the support part 15, and the left and right rails 17 are arranged with the front and back direction of the hopper 10 as an axis. The rails 17 are provided horizontally and in parallel, and the wheels 47 attached to the support arm 45 are placed on the rails 17.

As shown in FIG. 2, the gate part 25 of the gate body 21 is slightly longer than the length of the hopper outlet 13 in the front-back direction, and there are vertical partitions at the rear end 27 and both left and right ends of the gate part 25. A plate 37 is provided,
The upper end of the partition plate 37 is made to be slightly higher than the lower end of the hopper outlet 13 when the gate is closed. Furthermore, the partition plates 37 provided on the left and right sides of the gate section 25 are extended far further forward than the gate section 25, and after protruding in the horizontal direction from the front end 26 of the gate section, are made to protrude significantly diagonally upward.
The skirt portion 35 is formed by making the width in the vertical direction wider than the partition plate 37 portion. Further, the longitudinal support 32 of the gate main body 21 is connected to the rear end 2 of the gate portion.
7, and one end is pivoted to the rear end 23 of the gate body, which is the rear end of the longitudinal support 32,
A link rod 49 is provided whose other end is pivoted to the hopper inclined portion 12, and the rear end 42 of the opening/closing cylinder 41, on which the piston rod 43 is pivoted to the rear end of the longitudinal support 32, is also pivoted to the hopper inclined portion 12. (See Figures 2 and 3).

Since the embodiment of the hopper cutting device 20 according to the present invention is constructed as described above, when the opening/closing cylinder 41 is retracted, the link rod 49 is attached to the pivot point on the hopper inclined portion 12, as shown in FIG. Since the gate main body 21 is supported by the support arm 45 and the wheels 47, it moves horizontally to the rear of the outlet 13, and also moves behind the front-rear support column 32, which becomes the rear end 23 of the gate main body. Since the end is pivoted to the link rod 49, the rear end 23 of the gate body is lifted upward and tilted. Therefore, the skirt portion 35 that protrudes forward and obliquely upward from the gate body 21 allows the rear end 23 of the gate body 21 to move backward while the gate body 21 recedes in the horizontal direction.
Since the hopper can be lifted up, the hopper moves while descending to the left and right positions of the outlet 13 so as to cover the left and right sides of the outlet 13.

As mentioned above, when the gate of the hopper 10 is opened, in the embodiment of the present invention, the left and right sides of the hopper outlet 13 are covered by the skirt portion 35 provided on the gate body 21, so that the belt conveyor is closed as shown in FIG. 19 is stopped due to an accident such as a power outage, and even if the products in the hopper 10 continue to flow down to a certain point on the belt conveyor 19, the skirt portion 35 prevents the products from flowing out in the left and right direction, Overflow is prevented. or,
Since the skirt portion 35 is located above the gate body 21 when the hopper gate is closed, when a product loaded onto the belt conveyor 19 from another hopper passes under the hopper 10, It does not cause any trouble.

In the above embodiment, although the partition plates 37 are provided only on the left, right, and rear sides of the gate section 25, the gate section 25
If a partition plate is also provided at the front end 26 of the hopper 10, it is possible to stop the contents of the hopper 10 from flowing out without bringing the gate part 25 into close contact with the front end of the hopper outlet 13 when the gate is closed. In addition to extending forward from the left and right sides of the main body 21, the front ends of the left and right skirt portions 35 are connected to each other, so that three sides of the outlet 13 are connected to the skirt portion 35 when the gate is opened.
It can also be covered with

[Effects of the invention] The hopper cutting device according to the invention attaches the gate body to the hopper using support arms each having one wheel provided on the left and right sides of the gate body and a link rod at the rear end of the gate body. The gate can be opened and closed by rotating the rear end of the gate body vertically while moving it horizontally, and the skirt part provided on the gate body is positioned above the gate body when the gate is closed. However, there is no obstacle to the movement of the baggage on the belt conveyor, and when the gate is opened, the skirt portion covers at least the left and right sides of the hopper outlet, and the products falling from the outlet onto the belt conveyor are This prevents overflow from the left and right sides of the conveyor, and since the cylinder for opening and closing the gate is provided on the slope of the hopper, the space required for the cutting device can be reduced.
