Abstract

An automatic discharge hopper, comprising a main body (1) having an open structure at a lower end, and provided with a discharge plate (2) therebelow. The discharge plate (2) is pivoted to a lower terminal portion of the main body. The main body is symmetrically provided with two pneumatic cylinders (3). Piston rods of the pneumatic cylinders are pivoted to the discharge plate. A curved protrusion (21) is provided on the side of the discharge plate facing the main body. A pressure sensor used to detect a pressure on the discharge plate is mounted on the main body. When the pressure on the discharge plate reaches a preset pressure value, the piston rods of the pneumatic cylinders extend downward and drive the discharge plate to be inclined downward at a preset slope. In addition, the side of the main body facing the discharge plate is provided with the curved protrusion. In this way, the present invention enables a smooth discharge of a powder material, and achieves a rapid and automatic discharge of the material, thus saving manual labors, and improving operation efficiency.

Description

Automatic discharge hopper

Technical field

The utility model relates to a discharging tool, in particular to an automatic discharging hopper.

Background technique

Unloading hoppers are often used in factories, especially in the discharge of powder. However, the existing unloading hopper requires manual manual unloading during unloading, which wastes labor and affects work efficiency.

Utility model content

In order to solve the above technical problems, an object of the present invention is to provide an automatic unloading hopper that overcomes the deficiencies of the prior art.

In order to achieve the above object, the technical solution of the present invention is as follows:

An automatic unloading hopper includes a hopper body, the bottom end of the hopper body is an open structure, and a discharging plate is disposed below the hopper body, the discharging plate is hinged with a bottom end portion of the hopper body, and the hopper body is Two cylinders are symmetrically disposed, the telescopic rod of the cylinder is hinged with the discharge plate, and the discharge plate is provided with a curved convex portion facing one side of the discharge body, and the hopper body is installed on the hopper body. a pressure sensor for detecting the pressure on the discharge plate, when the pressure on the discharge plate reaches a set pressure value, the telescopic rod of the cylinder protrudes downward, thereby driving the discharge plate to tilt downward Set the slope.

As one of the preferred embodiments of the present invention, the arcuate convex portion has a hemispherical shape. However, it is not limited to a hemisphere, and may be an approximately hemispherical shape.

As one of the preferred embodiments of the present invention, the hopper body is provided with a blowing port, and the blowing port is connected to a high-pressure gas source for blowing the powder adhered to the inner wall of the hopper body.

As one of the preferred embodiments of the present invention, the curved surface convex portion is provided with a synovial layer.

Compared with the prior art, it has at least the following advantages:

1) When the pressure on the discharge plate reaches the set pressure value, the telescopic rod of the cylinder protrudes downward, thereby driving the discharge plate to tilt downward to set the inclination, and the discharge plate is disposed toward the side of the discharge body. The curved surface is convex, so that the powder can smoothly slide down, thereby achieving the effect of fast and automatic unloading, thereby saving manpower and improving work efficiency.

2) Preferably, when the hopper body is provided with a blowing port, it can be blown and adhered to the hopper body The powder on the inner wall acts to clean the inner wall of the hopper body.

DRAWINGS

In order to more clearly illustrate the structural features and technical points of the present invention, the present invention will be described in detail below with reference to the drawings and specific embodiments.

1 is a schematic structural view of an automatic unloading hopper disclosed in an embodiment of the present invention;

2 is a schematic structural view of a stripper plate disclosed in an embodiment of the present invention.

detailed description

The technical solutions in the embodiments will be specifically, clearly and completely described in the following with reference to the accompanying drawings in the embodiments.

Referring to FIG. 1 , an embodiment of the present invention discloses an automatic unloading hopper, including a hopper body 1 . The bottom end of the hopper body 1 is an open structure, and a discharging plate 2 , a discharging plate 2 and a hopper body are disposed below the hopper body 1 . The bottom end of the 1 is hinged, and the hopper body 1 is symmetrically disposed with two cylinders 3, the telescopic rod of the cylinder 3 is hinged with the unloading plate 2, and the side of the discharge plate 2 facing the discharge body is provided with a curved surface protrusion a pressure sensor for detecting the pressure on the discharge plate 2 is mounted on the hopper body 1. When the pressure on the discharge plate 2 reaches a set pressure value, the telescopic rod of the cylinder 3 extends downward, thereby driving the discharge. Plate 2 is tilted down to set the slope.

As one of the preferred embodiments of the present invention, the arcuate convex portion 21 has a hemispherical shape. However, it is not limited to a hemisphere, and may be an approximately hemispherical shape.

As one of the preferred embodiments of the present invention, the hopper body 1 is provided with a blow port 11 to which a high-pressure gas source is connected, and the blow port 11 is for blowing the powder adhered to the inner wall of the hopper body 1.

As one of the preferred embodiments of the present invention, the curved convex portion 21 is provided with a synovial layer, and the synovial layer can increase the smoothness of the surface of the curved convex portion 21, which can be more advantageous.

The working principle of the utility model is as follows:

When the discharge plate 2 accumulates enough powder, and the pressure on the discharge plate 2 reaches the set pressure value, the telescopic rod of the cylinder 3 protrudes downward, thereby driving the discharge plate 2 to tilt downwardly to set the inclination. And the side of the discharge plate 2 facing the discharge body is provided with a curved convex portion 21, so that the powder can smoothly slide down, thereby achieving the effect of rapid and automatic unloading, thereby saving manpower and improving work efficiency. . In addition, when the hopper The body 1 is provided with a blowing port 11, and if necessary, the powder adhered to the inner wall of the hopper body 1 can be blown off to function as an inner wall of the hopper body 1.
