Description

Technical Field

[0001] This utility model relates to a vibrating screen, and more particularly to an aggregate vibrating screen. Background Technology

[0002] Aggregates are granular materials that serve as the skeleton and filler in concrete and mortar. There are two types: fine aggregates and coarse aggregates. Fine aggregate particles have a diameter between 0.16 and 5 mm and are generally made of natural sand, such as river sand, sea sand, and valley sand. Coarse aggregate particles have a diameter greater than 5 mm and commonly include crushed stone and pebbles. Crushed stone concrete has higher strength than pebble concrete, but crushed stone is made by crushing rocks and is more expensive than pebble concrete. In the aggregate production process, an aggregate vibrating screen is used. During the vibrating screen process, water is used to wet the internal aggregates. Water and aggregates splash onto the inner wall of the machine, making it difficult to clean. Currently, most cleaning is done manually, which is time-consuming and labor-intensive.

[0003] Therefore, we need to design an aggregate vibrating screen with a cleaning function. Utility Model Content

[0004] In order to overcome the disadvantage that the internal cleaning is mostly done manually, which is time-consuming and labor-intensive, the present invention aims to provide an aggregate vibrating screen with a cleaning function.

[0005] To solve the above-mentioned technical problems, this utility model provides an aggregate vibrating screen, comprising a base, shock-absorbing springs, a vibrating screen motor, a vibrating screen protective plate, a conveyor cylinder, a mounting plate, an impact baffle, steel balls, a transmission rod, a bevel gear assembly, a mounting block, a double-acting screw, and a scraper. Shock-absorbing springs are symmetrically installed on the upper parts of both sides of the base. A vibrating screen protective plate is installed on the upper part of the base, with the upper ends of the shock-absorbing springs fixed to the vibrating screen protective plate. A vibrating screen motor is installed on the lower part of the vibrating screen protective plate, and the front part of the vibrating screen protective plate is movable. A conveyor cylinder is installed in a fixed manner. A mounting plate is fixedly connected to the upper rear end of the vibrating screen protective plate. A transmission rod is movably installed inside the mounting plate. An impact baffle is installed on the upper part of the transmission rod. A steel ball is movably installed on one side of the impact baffle. A bevel gear assembly is fixedly connected to the lower part of the transmission rod through the vibrating screen protective plate. A mounting block is installed on the lower part of the vibrating screen protective plate. A bidirectional screw is movably installed on the mounting block. One end of the bidirectional screw passes through the mounting block and is fixedly connected to the bevel gear assembly. A scraper is movably installed on the other end of the bidirectional screw.

[0006] Preferably, it also includes an atomizing nozzle and a water source connection pipe. The atomizing nozzle is installed inside the end of the vibrating screen protective plate away from the mounting plate, and the water source connection pipe is fixed to one end of the atomizing nozzle through the vibrating screen protective plate.

[0007] Preferably, it also includes a belt, a drive shaft, a connecting plate, and a stirring rod. The connecting plates are symmetrically installed on both sides of the vibrating screen protective plate near the conveyor cylinder. The stirring rod is movably installed on the connecting plate. One end of the stirring rod passes through the connecting plate and is connected to the belt. The drive shaft is installed at one end of the conveyor cylinder, and the other end of the belt is fitted onto the drive shaft.

[0008] Preferably, it also includes a grading feed plate, with the grading feed plate installed at the end of the vibrating screen protective plate away from the conveyor cylinder.

[0009] Preferably, it also includes a protective shell, with the protective shell mounted on the upper part of the mounting plate, and an impact baffle and steel ball installed inside the protective shell.

[0010] Preferably, the lower part of the vibrating screen protective plate is inclined.

[0011] This invention utilizes the rolling motion of steel balls to drive the impact baffle to rotate, which in turn drives the bevel gear assembly to rotate. The bevel gear assembly then drives the bidirectional screw to rotate, simultaneously causing the scraper to scrape back and forth under the vibrating screen's protective plate, thus achieving the effect of scraping and cleaning off the aggregate adhering to the inside.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0017] An aggregate vibrating screen, such as Figure 1 , Figure 2 and Figure 3As shown, the system includes a base 1, shock-absorbing springs 2, a vibrating screen motor 3, a vibrating screen protective plate 4, a conveyor cylinder 5, a mounting plate 8, a protective shell 801, an impact baffle 9, steel balls 10, a transmission rod 11, a bevel gear assembly 12, a mounting block 13, a double-acting screw 14, and a scraper 15. Shock-absorbing springs 2 are symmetrically installed on the upper sides of the base 1. The vibrating screen protective plate 4 is installed on the upper part of the base 1, with its lower part inclined. The upper ends of the shock-absorbing springs 2 are fixed to the vibrating screen protective plate 4. The vibrating screen motor 3 is installed on the lower part of the vibrating screen protective plate 4. The conveyor cylinder 5 is movably installed at the front of the vibrating screen protective plate 4, through which workers feed aggregate. The mounting plate 8 is fixed to the upper rear end of the vibrating screen protective plate 4. The protective shell 801 is installed on the upper part of the mounting plate 8. The impact baffle 9 and steel balls 10 are installed inside the protective shell 801. The interior of the mounting plate 8 is movably... A transmission rod 11 is installed, and an impact baffle 9 is installed on the upper part of the transmission rod 11. A steel ball 10 is movably installed on one side of the impact baffle 9. When the steel ball 10 rolls, it pushes the impact baffle 9 to rotate. Under the impact of the weight of the steel ball 10, it drives the bevel gear assembly 12 to rotate. The lower part of the transmission rod 11 passes through the vibrating screen protection plate 4 and is fixed to the bevel gear assembly 12. An installation block 13 is installed on the lower part of the vibrating screen protection plate 4. A bidirectional screw 14 is movably installed on the installation block 13. The right end of the bidirectional screw 14 passes through the installation block 13 and is fixed to the bevel gear assembly 12. A scraper 15 is movably installed on the left end of the bidirectional screw 14. The impact baffle 9 drives the bevel gear assembly 12 to rotate, and the bevel gear assembly 12 drives the bidirectional screw 14 to rotate. At the same time, it drives the scraper 15 to scrape back and forth on the lower part of the vibrating screen protection plate 4, which can achieve the effect of scraping off the aggregate adhering inside.

[0018] When the worker feeds the aggregate from the conveyor cylinder 5, the aggregate enters the vibrating screen protective plate 4. The vibrating screen motor 3 drives the protrusion to rotate. Under the action of the damping spring 2, the vibrating screen achieves a damping effect, which shakes the filter screen at the top. At this time, the rolling of the steel ball 10 pushes the impact baffle 9 to rotate. The impact baffle 9 drives the bevel gear assembly 12 to rotate, and the bevel gear assembly 12 drives the bidirectional screw 14 to rotate. At the same time, it drives the scraper 15 to scrape back and forth at the bottom of the vibrating screen protective plate 4, which can achieve the effect of scraping off the aggregate adhering inside. Example 2

[0019] Based on Example 1, such as Figure 2As shown, it also includes an atomizing nozzle 6, a grading feed plate 16, a water source connection pipe 7, a belt 17, a drive shaft 1701, a connecting plate 18, and a stirring rod 19. An atomizing nozzle 6 is installed inside the vibrating screen protective plate 4 at the end furthest from the mounting plate 8. The atomizing nozzle 6 sprays water onto the surface of the aggregate. The left end of the atomizing nozzle 6 passes through the vibrating screen protective plate 4 and is fixedly connected to the water source connection pipe 7. When the water source connection pipe 7 is connected to an external water source, a water pump is driven to draw water to the atomizing nozzle 6. The grading feed plate 16 is installed on the right side of the vibrating screen protective plate 4 furthest from the conveyor cylinder 5, and the aggregate then enters the grading feed plate. At the feeding plate 16, when passing through the discharge port, the finer aggregate falls onto the second grading feeding plate 16. The vibrating screen protection plate 4 is symmetrically installed with connecting plates 18 on both sides near the conveyor cylinder 5. The connecting plate 18 is movably installed with a stirring rod 19, which drives the stirring rod 19 to rotate, thus breaking up the aggregate at the inlet. The left end of the stirring rod 19 passes through the connecting plate 18 and is connected to a belt 17. The left end of the conveyor cylinder 5 is equipped with a drive shaft 1701, which is driven by other motors to rotate. The lower end of the belt 17 is fitted onto the drive shaft 1701.

[0020] The aggregate enters the grading feed plate 16. When passing the discharge port, the finer aggregate falls onto the second grading feed plate 16. At this time, when the water source connection pipe 7 is connected to the external water source, the water pump is driven to draw water to the atomizing nozzle 6. Under the drive of other motors, the drive shaft 1701 is rotated. When the drive shaft 1701 rotates, it drives the belt 17 to rotate, which in turn drives the stirring rod 19 to rotate, thus breaking up the aggregate at the inlet. The aggregate is moistened to facilitate its dispersal. During the vibration process, the aggregate will splash onto the inner wall of the vibrating screen protective plate 4.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
