Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibrating screen technology, specifically a vibrating screen with a collection function. Background Technology
[0002] Vibrating screens, as important screening equipment in industrial production, are widely used in mining, metallurgy, chemical, food, building materials and other fields. Their main function is to classify and screen materials of different particle sizes and densities through vibration to meet the needs of subsequent production processes. Traditional vibrating screens typically consist of core components such as a screen box, a vibrating motor, and a support device. During operation, the excitation force generated by the vibrating motor causes the material to reciprocate on the screen surface, thereby achieving the separation of coarse and fine materials.
[0003] A search revealed that patent publication number CN207615184U discloses a vibrating screen with a collection function, relating to the field of vibrating screen technology. This vibrating screen with a collection function includes a body, with connecting members fixedly connected to the left and right sides of the front and rear sides of the body. A first spring is fixedly connected to the bottom of each connecting member, and the bottom of the first spring is fixedly connected to the top of a support leg. A housing is provided on one side of the body, and connecting plates are provided on both sides of the front and rear surfaces of the housing. This vibrating screen with a collection function effectively improves the vibration effect of the screen by setting a first spring between the connecting member and the support leg, and by ensuring that the spring force of the first spring is greater than the weight of the machine. By setting a second spring inside the housing, the spring force of the second spring can push the locking block into the groove, allowing a third spring to extend the fixing block to the outside of the body, thereby achieving the effect of fixing the housing to the body.
[0004] In actual use, existing vibrating screens with collection functions cause particles to collide and rub against each other when screening fine or dry materials such as ores, cement, and coal powder. At the same time, the vibration of the screen surface also causes fine particles to detach from the material layer, generating a large amount of dust. This dust not only permeates the production workshop, leading to a deterioration of the working environment and harming the health of operators (such as causing respiratory diseases like pneumoconiosis), but may also pollute the surrounding atmosphere and violate environmental protection regulations. Therefore, a vibrating screen with a collection function needs to be designed. Utility Model Content

[0017] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:
[0018] 1. In this utility model, through a series of coordinated structural arrangements, when the equipment screens materials, the geared motor on the drive assembly and the fan on the dust collection mechanism are started. The operator feeds the material from the feeding trough into the housing. The geared motor starts and drives the first rotating shaft to rotate. When the first rotating shaft rotates, it drives the second rotating shaft to rotate. When the second rotating shaft rotates, it drives the cam to rotate. When the cam rotates, it creates a reciprocating force on the plate screen. The plate screen vibrates in a certain direction due to the reciprocating force. When the plate screen vibrates, it can screen the material. During the screening process, a certain amount of dust is generated. When the fan starts, the suction hood has a certain suction force. The suction hood sucks up the dust inside the housing and transports it into the box for collection. Thus, when the equipment screens materials, it can suck up and collect the dust generated during the screening process, avoiding the dust pollution of the working environment.
[0019] 2. In this utility model, through a series of coordinated structural arrangements, when the dust drawn in by the suction hood enters the box, the plate filter inside the box filters and blocks the dust. The blocked dust falls into the collection tank for collection. When the first rotating shaft rotates, it drives the third rotating shaft on the cleaning component to rotate. When the third rotating shaft rotates, it drives the fourth rotating shaft to rotate. When the fourth rotating shaft rotates, it drives the brush plate to rotate. When the brush plate rotates, it can clean the bottom of the plate filter, avoiding the situation where dust clogs the plate filter and reduces the dust absorption effect. It also eliminates the need for frequent manual cleaning of the plate filter, reducing the workload of workers and improving the production efficiency of material screening.

[0048] Working Principle: When in use, connect the external power supply. When the equipment is screening materials, start the geared motor 131 on the drive assembly 130 and the fan 240 on the dust collection mechanism 200. The operator feeds the material from the feeding trough 121 into the housing 110. The geared motor 131 drives the first rotating shaft 133 to rotate, which in turn drives the second rotating shaft 135 to rotate. The second rotating shaft 135 then drives the cam 136 to rotate, which in turn exerts a reciprocating force on the plate screen 140. This reciprocating force causes the plate screen 140 to vibrate in a certain direction, screening the material. During screening, dust is generated. The fan 240 then creates suction on the suction hood 111, which draws in the dust from inside the housing 110 and transports it to the box 210 for collection. When screening materials, the dust generated during the screening process can be collected, preventing dust pollution of the working environment. When the dust collected by the suction hood 111 enters the box 210, the plate filter 220 inside the box 210 filters and blocks the dust, which falls into the collection tank 270 for collection. When the first rotating shaft 133 rotates, it drives the third rotating shaft 261 on the cleaning component 260 to rotate. When the third rotating shaft 261 rotates, it drives the fourth rotating shaft 266 to rotate. When the fourth rotating shaft 266 rotates, it drives the brush plate 265 to rotate. When the brush plate 265 rotates, it can clean the bottom of the plate filter 220, preventing dust from clogging the plate filter 220 and reducing the dust collection effect. It also eliminates the need for frequent manual cleaning of the plate filter 220, reducing the workload of the staff and improving the production efficiency of material screening.
[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
