Description

Technical Field

[0001] This utility model relates to the field of sand and gravel aggregate processing technology, and in particular to a sand and gravel aggregate gradation screening and fixing device. Background Technology

[0002] Sand and gravel aggregate processing refers to the process of processing mined natural rocks, organic materials, and other usable solid materials into sand and gravel granular materials that meet the specifications required for different engineering construction and industrial production through a series of crushing, screening, and washing processes. The development of the sand and gravel aggregate processing industry will drive related upstream and downstream industries. Upstream, it will promote the mining and machinery manufacturing industries, and downstream, it will promote the progress of many industries such as construction, building materials, and water conservancy, forming a complete industrial chain. With the acceleration of urbanization and the country's heavy investment in transportation and energy infrastructure construction, a large number of construction projects, water conservancy projects, railway and highway projects are constantly being launched. High-quality sand and gravel aggregate processing can ensure that these projects have a sufficient and qualified supply of raw materials, promote the continuous improvement of infrastructure, and promote the sustainable development of the economy and society.

[0003] In actual processing, sand and gravel aggregate raw materials have different particle size requirements. In order to meet the needs of different engineering construction scenarios, screening devices are often required to screen the sand and gravel aggregate raw materials. Most existing screening devices adopt a single screen structure, which can effectively screen the raw materials, but lacks a pre-treatment structure. They lack effective treatment for large-sized aggregates in the raw materials, making large aggregates easy to get stuck in the screen, thereby reducing screening efficiency. This limits the application scenarios of the screening devices and reduces their service life. Utility Model Content

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, aggregate is poured into the pretreatment cylinder through a feeding funnel. The servo motor is started, and the rotating disk is driven to rotate through the transmission rod. The extrusion block 1 on the rotating disk is continuously in contact with the extrusion block 2, thereby lifting the extrusion block 2. This causes the internal vibrating plate to vibrate up and down, preventing large-sized aggregate from falling through the through hole. The hydraulic rod is started to drive the push plate to move, thereby pushing the large-sized aggregate on the vibrating plate to be discharged from the pretreatment cylinder through the discharge inclined plate. The aggregate passing through the vibrating plate then enters the next step of screening, thus achieving the purpose of pretreatment of aggregate, expanding the application scenarios of the device, and improving the service life of the device.

[0022] 2. In this utility model, when the aggregate falls from the pretreatment cylinder onto the conveyor plate, the servo motor is started to drive the conveyor plate to move to the left. Small-sized aggregates fall through the holes on the conveyor plate into the next layer and are collected into the collection box through the collection funnel. Aggregates that cannot pass through the holes move with the conveyor plate and leave the conveyor plate through the fixed inclined plate. Baffles are provided on the adjacent sides of the two rotating wheels to prevent aggregates falling into the conveyor plate from damaging the rotating wheels. The design of the fixed ring and the stop block prevents the aggregates from being thrown out from the front and rear sides of the conveyor plate, thus achieving the purpose of collecting aggregates and reducing the loss of raw materials.

[0039] Working principle: When it is necessary to screen sand and gravel aggregates, the aggregates are first poured into the pretreatment cylinder 3 through the feed funnel 1 for pretreatment. The servo motor 11 is started by the controller 22. Under the output of the servo motor 11, the bottom rotating disk 12 is driven to rotate through the transmission rod 10. Through the rotation of the rotating disk 12, the extrusion block 13 on the rotating disk 12 continuously contacts the extrusion block 14, thereby lifting the extrusion block 14. After contact, the extrusion block 14 falls naturally. The up and down movement of the extrusion block 14 drives the connecting rod 9 and the fixed plate 8 to move up and down, thereby causing the internal vibrating plate 4 to vibrate up and down, thus pre-screening the aggregates and preventing large-sized aggregates from falling through the through hole 5. Then, the hydraulic rod 6 is started to drive the push plate 7 to move, thereby pushing the large-sized aggregates on the vibrating plate 4 from the right side of the pretreatment cylinder 3 through the discharge inclined plate 15 and discharged from the pretreatment cylinder 3. The aggregates that pass through the vibrating plate 4 enter the next step of screening.

[0040] The collection mechanism 2 can further screen the aggregate and collect the small-sized aggregates after screening. When the aggregates fall from the pretreatment cylinder 3 onto the conveyor plate 202, the servo motor 201 is started to drive the conveyor plate 202 to the left through the rotating wheel 209. The small-sized aggregates on the conveyor plate 202 fall into the next layer through the holes 203 on the conveyor plate 202 and are collected into the collection box 206 through the collection funnel 205. The aggregates that cannot pass through the holes 203 move with the conveyor plate 202 and leave the conveyor plate 202 through the fixed inclined plate 23. The adjacent sides of the two rotating wheels 209 are provided with baffles 211 to prevent the aggregates falling into the conveyor plate 202 from damaging the rotating wheels 209. The design of the fixed ring 207 and the stop block 208 can prevent the aggregates from being thrown out from the front and rear sides of the conveyor plate 202 and not collected into the collection funnel 205, thus reducing the loss of raw materials.
