A hopper with adjustable outlet size

Abstract

The invention provides a discharging-opening-adjustable hopper. The discharging-opening-adjustable hopper comprises two bases, the two bases are each provided with a supporting device, the upper portions of the supporting devices are in bearing connection with first rotating rods, multiple stretching devices are arranged on the first rotating rods, the uppermost stretching devices are slidingly connected with first limiting devices, a fixed ring is arranged on the side, located on the first limiting devices, on the stretching devices, first arc grooves are formed in the sides, located on the multiple stretching devices, at the lower portion of the fixed ring, the arc grooves and the fixed ring are aslant arranged, and the stretching devices and the first arc grooves in the two first rotating rods are rotationally and symmetrically arranged. According to the discharging-opening-adjustable hopper, by arranging the first limiting devices, the transverse directions of the stretching devices are limited, then the first rotating rods rotate through longitudinal limiting devices, the first arc grooves in the specified first stretching rods are rotated, and it is achieved that a lower opening of the hopper is adjusted.

Description

technical field [0001] The invention relates to the technical field of conveying equipment, and mainly relates to a hopper with an adjustable discharge port. Background technique [0002] The hopper refers to the equipment manufactured when the feed inlet of the material is limited, or when the feed inlet is too small or too large, and the amount of feed is difficult to control. The amount of feed is controlled through the hopper and the solution The feeding port is too large or too small. [0003] The existing hopper is, for example, a retractable hopper with patent No. 201610721899.5, which slides from top to bottom to realize the contraction of the hopper so that the practicability of the hopper is increased. [0004] However, when the material is introduced into the hopper, the size of the feed port is different, and the control of the material introduction speed is different, and then the size of the lower opening of the hopper needs to be adjusted, while the size of t...

[0004] However, when the material is introduced into the hopper, the size of the feed port is different, and the control of the material introduction speed is different, and then the size of the lower opening of the hopper needs to be adjusted, while the size of the lower opening of the existing hopper is fixed, so when used It is necessary to find a suitable hopper diameter for material guidance, which increases the cost
