Description

Technical Field

[0001] This utility model relates to the technical field of putty powder unloading devices, specifically to a putty powder unloading bin. Background Technology

[0002] Traditionally, putty powder is unloaded into a hopper by opening a bag containing the powder from the top of the hopper. The putty powder then pours from the bag into the hopper. However, due to static electricity generated by the friction between the putty powder and the bag, the bag openings tend to stick together after unloading, resulting in a lot of residual putty powder in the bags and incomplete unloading. This requires workers to climb up to the top of the hopper and use their hands to open the bags or to tap them with sticks to ensure that the putty powder inside falls completely. This method is not only inefficient, but also poses a risk of accidents for workers climbing. Therefore, there is an urgent need for a device that can cleanly unload putty powder without requiring manual climbing. Utility Model Content

[0003] The purpose of this utility model is to provide a putty powder unloading bin.

[0004] This utility model provides the following technical solution:

[0005] This utility model proposes a putty powder unloading bin, including a hopper and a pair of blowers located next to the hopper. The blowers are connected to an air outlet pipe, which passes through the hopper. The air outlet of the air outlet pipe is located inside the hopper and faces upward. A cover plate is hinged to the air outlet of the air outlet pipe. A limiting member is fixed to the air outlet pipe. The limiting member is located behind the hinge point of the cover plate and is used to prevent the cover plate from flipping over to a vertical position when it rotates.

[0006] Furthermore, the air outlet is an angled opening, which is at an angle of 30-60° relative to the horizontal.

[0007] Furthermore, the air outlet is located at 1 / 3 to 2 / 3 of the distance from the side wall of the hopper.

[0008] Furthermore, the limiting element is a limiting block.

[0009] Compared with the existing technology, this utility model has a simple structure and is easy to operate. It uses a blower to blow air to support the bag and uses a limiting component to prevent the cover from rotating beyond the vertical position. When the blower is turned off, the cover can cover the air vent under the action of gravity. This solves the problems of low efficiency and safety in traditional putty powder unloading, which requires manual climbing and holding the bag open by hand or hitting it with sticks.

[0015] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0016] In one embodiment of this utility model, a putty powder unloading bin includes a hopper 1 and a pair of blowers 2 located next to the hopper 1. The blowers 2 are connected to an air outlet pipe 3, which passes through the hopper 1. The air outlet 31 of the air outlet pipe is located inside the hopper 1 and faces upward. A cover plate 5 is hinged to the air outlet 31 of the air outlet pipe 3. A limiting member 6 is fixed to the air outlet pipe 3. The limiting member 6 is located behind the hinge point of the cover plate 5 and is used to prevent the cover plate 5 from flipping over when it rotates. In actual application, the blower 2 blows the cover plate 5 up, and the air from the blower 2 blows upward to open the bag of putty powder. Then the blower 2 is turned off, and the cover plate 5 covers the air outlet around the hinge point under the action of its weight, and the putty powder stuck to the bag also falls down.

[0017] In one embodiment of the present invention, a support base 4 for fixing to a wall is also included, and the blower 2 is fixed on the support base 4.

[0018] In one embodiment of this utility model, the air outlet 31 is an oblique opening, and the angle α of the oblique opening relative to the horizontal is 30-60°; in order to avoid the putty powder pressing down on the cover and to prevent the blower 2 from blowing up the cover plate 5.

[0019] In one embodiment of this utility model, the air outlet 31 is located 1 / 3 to 2 / 3 of the distance from the side wall of the hopper, so as to facilitate the blower 2 to blow air and open the bag of putty powder.

[0020] In one embodiment of this utility model, the limiting member 6 is a limiting block; the limiting block prevents the cover plate from flipping over to the vertical state, so that after the blower is turned off, the cover plate will cover the air outlet around the hinge point under the action of weight.

[0021] In practical applications, the blower blows air to lift the cover plate, and the air from the blower blows upward to open the bag of putty powder. Then the blower is turned off, and the cover plate, under its own weight, covers the air vent around the hinge point, and the putty powder stuck to the bag also falls off.

[0022] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
