Shot blasting machine with feeding hopper, connecting shaft and supporting bearing

Abstract

The invention provides a shot blasting machine with a feeding hopper, a connecting shaft and a supporting bearing. The shot blasting machine further comprises the feeding hopper, the connecting shaft and the supporting bearing, wherein the feeding hopper is arranged in front of a sliding door; one end, far from the sliding door, of the feeding hopper is provided with a lifting rope; one end, close to the sliding door, of the feeding hopper is rotatably connected to a main body part of the shot blasting machine; one end of the connecting shaft is connected to the sliding door by fixing; the other end of the connecting shaft is connected to the supporting bearing; the shaft length of the connecting shaft is smaller than one third of the width of the sliding door; and the supporting bearing comprises two bearings. The shot blasting machine provided by the invention has the beneficial effects of being simple in structure, delicate in design, safe and convenient, energy-saving, time-saving, labor-saving and the like.

Description

technical field [0001] The invention relates to a shot blasting machine, in particular to a shot blasting machine with a feeding hopper, a connecting shaft and a support bearing. Background technique [0002] With the development of science and technology, the current shot blasting machine gradually adopts new technology. In the past, the shot blasting door was opened manually by hand, but now it begins to use hydraulic pressure, air pressure and other methods to open and close the door semi-automatically. When the cylinder-type door is used, the sliding door is usually directly pulled up vertically. This may cause the weight of the sliding door to be large, and a single cylinder is not enough to directly pull it up, so 2 Or more cylinders can be operated, which greatly increases the cost. [0003] Moreover, because the cylinder is connected with the sliding door at a single point, when the cylinder pulls the sliding door, it is easy to cause the sliding door to be unbalanc...

AI Technical Summary

Problems solved by technology

When using the cylinder type to open and close the door, usually the sliding door is directly lifted up vertically, which may cause the weight of the sliding door to be heavy, and a single cylinder is not enough to pull it up directly, and two cylinders are required or more cylinders can be operated, which greatly increases the cost

[0003] Moreover, because the cylinder is connected to the sliding door at a single point, when the cylinder pulls the sliding door, it is easy to cause the sliding door to be unbalanced, causing a corner of the sliding door to tilt and get stuck on the shot blasting machine, so that the cylinder can no longer pull the sliding door. cause damage

[0004] In addition, the shaft length of the previous connecting shaft exceeds half the width of the sliding door. When the sliding door is stuck, a huge force acts on it, which can easily cause damage or even damage to the connecting shaft.

Moreover, the supporting bearings connected to the connecting shaft are all single bearings, and the width of the bearing is smaller than the width of the side in contact with the shot blasting machine, which is likely to cause the overall shaking and make the sliding door stuck

[0005] In addition, the current cylinder type semi-automatic switch door has only two states of open or closed stroke control, that is, it cannot stop working when the switch is opened, and there is no half-open state. A trip, a waste of electricity, and a waste of time
