Description

Technical Field

[0001] This invention relates to the field of manufactured sand pushing devices, and more particularly to a manufactured sand pushing device with a crushing structure. Background Technology

[0002] Manufactured sand refers to sand produced by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different shapes and sizes according to different process requirements, which can better meet daily needs.

[0003] Manufactured sand requires multiple processing equipment such as transportation, crushing, and drying. However, existing manufactured sand pushing devices take a long time to transport the manufactured sand to the crushing equipment, where it is then crushed. After the manufactured sand pushing device finishes transporting the sand, a large amount of manufactured sand powder remains on its surface, requiring subsequent cleaning by staff, which affects the efficiency of manufactured sand production.

[0004] Therefore, to address the issues that existing manufactured sand pushing devices lack crushing capabilities and leave a large amount of manufactured sand powder on their surface after transportation, requiring subsequent cleaning and impacting production efficiency, a manufactured sand pushing device with a crushing structure can be designed. This device crushes the manufactured sand through a crushing mechanism. During crushing, the first screw makes the crushing screen plate contact the ground of the crushing mechanism, facilitating the compression and crushing of the manufactured sand and improving crushing efficiency. After the manufactured sand is transported by the conveyor belt mechanism, the conveyor belt mechanism is cleaned by a support and cleaning mechanism. Summary of the Invention

[0005] In order to overcome the problem that the existing manufactured sand pushing device does not have the function of crushing, and that a large amount of manufactured sand powder remains on the surface of the manufactured sand pushing device after the transportation is completed, which requires the staff to clean it and affects the production efficiency of manufactured sand.

The top of the cleaning brush is in contact with the outer end face of the conveyor belt mechanism.

[0009] Preferably, the manufactured sand is crushed by a crushing mechanism. During the crushing process, the first screw makes the crushing screen plate contact the ground of the crushing mechanism, which facilitates the crushing of the manufactured sand and improves the crushing efficiency. After the manufactured sand is transported by the conveyor belt mechanism, the conveyor belt mechanism is cleaned by the support and cleaning mechanism.

[0010] Preferably, the front end of the crushing seat is provided with a feed inlet, the bottom end of the crushing seat is provided with a discharge outlet, the bottom end of the feed inlet extends above the discharge outlet, and the feed inlet and the discharge outlet are connected in a continuous manner.

One end of the connecting hose extends through the crushing seat to the inside of the water tank. The top of each nozzle is provided with a first displacement groove at the top of the inner wall of the crushing seat. The top of the nozzle extends to the inside of the first displacement groove. The rear end of each nozzle is provided with a second lead screw at the inner wall of the first displacement groove. One end of the second lead screw extends through the nozzle and the crushing seat to one side of the first lead screw. The nozzle and the second lead screw mesh with each other.

[0012] Preferably, there are two second lead screws, which are located on both sides of the first lead screw and are symmetrical about the first lead screw. A bevel gear is provided at one end of each of the two second lead screws and at the intersection of the first lead screw and the two second lead screws. The first lead screw is connected to the two second lead screws through the bevel gears.

[0013] Preferably, the crushing screen plate has guide grooves on both sides of the inner wall of the crushing seat, and the two sides of the crushing screen plate extend to the inner side of the guide grooves. A threaded hole is provided at the center of the crushing screen plate, and the bottom end of the first lead screw extends through the threaded hole to the bottom end of the inner wall of the crushing seat.

The toothed blocks on the outer side of the four crushing rollers are arranged in an alternating manner. The crushing rollers and the auxiliary drive wheel are integrated into one structure. The main drive wheel has an output end located at one end of the second servo motor. The second servo motor is connected to the main drive wheel through a coupling. Both the main drive wheel and the auxiliary drive wheel have drive belts on their inner sides. The main drive wheel and the auxiliary drive wheel are connected by drive belts.

[0018] The beneficial effects of this invention are:

[0019] 1. The manufactured sand is crushed by the crushing mechanism. During the crushing process, the first screw rotates in both directions. Since the crushing screen plate is meshed with the first screw, the crushing screen plate moves up and down during the rotation of the first screw, which facilitates the crushing of the manufactured sand and improves the crushing efficiency. The first screw is connected to the second screw on the inner wall of the crushing seat, and the nozzle is meshed with the second screw. This allows the second screw to drive the nozzle to move repeatedly on the inner wall of the crushing seat when the first screw rotates in both directions, which expands the spraying area of ​​the nozzle and reduces dust on the crushing seat.

[0020] 2. After the manufactured sand is crushed and transported by the conveyor belt mechanism, the conveyor belt mechanism contacts the cleaning displacement seat at the top of the supporting cleaning mechanism through the partition. The cleaning brush at the top of the cleaning displacement seat is in contact with the outer end face of the conveyor belt mechanism, which facilitates the contact of the cleaning displacement seat with the partition. The cleaning displacement seat moves on the supporting cleaning mechanism and cleans the conveyor belt mechanism through the cleaning brush. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] Please see Figures 1-6 The present invention provides a technical solution: a manufactured sand pushing device with a crushing structure, including a device base 1, a conveyor belt mechanism 2 provided on the inner side of the device base 1, partitions 10 provided on both sides of the top surface of the conveyor belt mechanism 2, a crushing seat 5 provided above one end of the conveyor belt mechanism 2 at the upper end of the device base 1, a feed inlet 6 provided on the front end of the crushing seat 5, a discharge outlet provided at the bottom end of the crushing seat 5, the bottom end of the feed inlet 6 extending above the discharge outlet, the feed inlet 6 and the discharge outlet being connected in a continuous manner, a first servo motor 9 provided above the crushing seat 5, a drive seat 7 provided at the bottom end of the first servo motor 9, water tanks 8 provided on both sides of the drive seat 7 at the top of the crushing seat 5, a first lead screw 15 provided at the bottom end of the first servo motor 9, the bottom end of the first lead screw 15 extending through the drive seat 7 to the bottom end of the inner wall of the crushing seat 5, thereby feeding uncrushed manufactured sand into the inner side of the crushing seat 5 through the feed inlet 6, and then crushing the manufactured sand through the crushing mechanism 12;

[0031] Example 2

[0032] Please see Figures 2-4 In this embodiment, nozzles 11 and crushing mechanisms 12 are sequentially arranged on both sides of the first lead screw 15 inside the crushing base 5. A crushing screen plate 13 is located below the crushing mechanism 12 at the bottom end of the first lead screw 15. Two nozzles 11 are provided, with a connecting hose at the rear end of each nozzle 11. One end of the connecting hose extends through the crushing base 5 to the inside of the water tank 8. A first displacement groove 16 is provided above the top of the inner wall of the crushing base 5 for each nozzle 11, extending to the inside of the first displacement groove 16. A second lead screw 17 is provided at the rear end of each nozzle 11 on the inner wall of the first displacement groove 16. One end of the second lead screw 17 extends through the nozzle 11 and the crushing base 5 to one side of the first lead screw 15. The nozzles 11 and the second lead screw 17 mesh with each other. Two second lead screws 17 are provided. Located on both sides of the first lead screw 15, two second lead screws 17 are symmetrical about the first lead screw 15. A bevel gear 18 is provided at one end of the two second lead screws 17 and at the intersection of the first lead screw 15 and the two second lead screws 17. The first lead screw 15 is connected to the two second lead screws 17 through the bevel gear 18. When the crushing mechanism 12 crushes the manufactured sand, the first servo motor 9 drives the first lead screw 15 to rotate inside the crushing seat 5. Since the first lead screw 15 is connected to the second lead screw 17 on the inner wall of the crushing seat 5, and the nozzle 11 meshes with the second lead screw 17, it is convenient for the second lead screw 17 to drive the nozzle 11 to repeatedly move on the inner wall of the crushing seat 5 when the first lead screw 15 rotates in both directions, so as to expand the spraying area of ​​the nozzle 11 and perform dust suppression on the crushing seat 5.

[0033] Example 3

[0034] Please see Figures 2-3In this embodiment, the crushing mechanism 12 includes a crushing roller 1201 and a second servo motor 1202. The crushing roller 1201 and the second servo motor 1202 are located at both ends of the crushing mechanism 12. One end of the crushing roller 1201 and the second servo motor 1202 are respectively located on the inner side of the crushing mechanism 12 and are provided with a main drive wheel 1203 and a secondary drive wheel 1205. Both sides of the crushing screen plate 13 are provided with guide grooves 14 on the inner wall of the crushing seat 5. Both sides of the crushing screen plate 13 extend to the inner side of the guide grooves 14. A threaded hole is provided at the center of the crushing screen plate 13. The bottom end of the first lead screw 15 extends through the threaded hole to the bottom end of the inner wall of the crushing seat 5. The first lead screw 15 meshes with the crushing screen plate 13. There are four crushing rollers 1201. The outer side of each of the four crushing rollers 1201 is provided with toothed blocks. The toothed blocks on the outer side of the four crushing rollers 1201 are arranged alternately. The main drive wheel 1203 and the auxiliary drive wheel 1205 are integrated into one structure. The main drive wheel 1203 is located at one end of the second servo motor 1202 and has an output end. The second servo motor 1202 is connected to the main drive wheel 1203 through a coupling. Both the main drive wheel 1203 and the auxiliary drive wheel 1205 are equipped with a drive belt 1204 on their inner sides. The main drive wheel 1203 and the auxiliary drive wheel 1205 are connected by the drive belt 1204. The top surface of the crushing screen plate 13 is consistent with the shape of the four crushing rollers 1201. The top surface of the crushing screen plate 13 is in contact with the bottom surface of the four crushing rollers 1201. When the crushing mechanism 12 is crushing, the first screw 15 rotates in both directions. Since the crushing screen plate 13 and the first screw 15 are meshed with each other, the crushing screen plate 13 moves up and down during the rotation of the first screw 15, which facilitates the crushing of the manufactured sand and improves the crushing efficiency.

[0035] Example 4

[0036] Please see Figures 5-6In this embodiment, a storage base 4 is provided at the bottom of the device base 1. Three sets of supporting cleaning mechanisms 3 are provided on both sides of the storage base 4 below the device base 1. Each supporting cleaning mechanism 3 includes a supporting base 301, a supporting displacement frame 302, a cleaning displacement seat 303, and a cleaning brush 304. The supporting displacement frame 302 is located at the center of the supporting base 301, the cleaning displacement seat 303 is located on both sides of the top surface of the supporting displacement frame 302, and the cleaning brush 304 is located at the top of the cleaning displacement seat 303. The top of the cleaning brush 304 is in contact with the outer end face of the conveyor belt mechanism 2. Two supporting bases 301 are provided, and the supporting displacement frame 302 is located at the center of the two supporting bases 301. Both ends of the supporting displacement frame 302 extend to the inner sides of the two supporting bases 301. Second displacement grooves 19 are provided on both sides of the cleaning displacement seat 303 inside the supporting displacement frame 302. One end of 03 is located on the inner wall of the second displacement groove 19 and is provided with a connecting spring 20. The cleaning displacement seat 303 is movably connected to the support displacement frame 302 through the connecting spring 20. One end of the cleaning displacement seat 303 and the opposite surface of the partition plate 10 and the cleaning displacement seat 303 are both inclined surfaces. The cleaning displacement seat 303 and the partition plate 10 are attached to each other through the inclined surfaces. When the crushed sand falls into the top of the conveyor belt mechanism 2 for conveying, after the conveyor belt mechanism 2 has finished conveying, the conveyor belt mechanism 2 contacts the cleaning displacement seat 303 at the top of the support cleaning mechanism 3 through the partition plate 10. The cleaning brush 304 at the top of the cleaning displacement seat 303 is attached to the outer end face of the conveyor belt mechanism 2, so that the cleaning displacement seat 303 is contacted by the partition plate 10. The cleaning displacement seat 303 moves in the support cleaning mechanism 3. The cleaning displacement seat 303 cleans the conveyor belt mechanism 2 through the cleaning brush 304.

[0037] During operation, the power is turned on and the device is started. The manufactured sand to be crushed is fed into the crushing seat 5 through the feed inlet 6. The crushing mechanism 12 then pulverizes the sand. While the crushing mechanism 12 is crushing the sand, the first lead screw 15 rotates in both directions. Because the crushing screen plate 13 meshes with the first lead screw 15, the screen plate 13 moves up and down during the rotation of the first lead screw 15, facilitating the compression and crushing of the manufactured sand and improving crushing efficiency. Furthermore, because the first lead screw 15 is connected to the second lead screw 17 on the inner wall of the crushing seat 5, and the nozzle 11 meshes with the second lead screw 17, the second lead screw 17 is driven by the first lead screw 15 during its rotation. The moving nozzle 11 repeatedly moves within the inner wall of the crushing seat 5 to expand the spraying area of ​​the nozzle 11 and reduce dust in the crushing seat 5. After the crushed sand is transported, it falls into the top of the conveyor belt mechanism 2. After the conveyor belt mechanism 2 has finished transporting, the conveyor belt mechanism 2 contacts the cleaning displacement seat 303 at the top of the supporting cleaning mechanism 3 through the partition 10. The cleaning brush 304 at the top of the cleaning displacement seat 303 is in contact with the outer end face of the conveyor belt mechanism 2, which facilitates the contact of the cleaning displacement seat 303 with the partition 10. The cleaning displacement seat 303 moves within the supporting cleaning mechanism 3 and cleans the conveyor belt mechanism 2 through the cleaning brush 304.

[0038] Through the above steps, the manufactured sand is crushed by the crushing mechanism 12. During the crushing process, the first screw 15 makes the crushing screen plate 13 contact the ground of the crushing mechanism 12, which facilitates the crushing of the manufactured sand and improves the crushing efficiency. After the manufactured sand is conveyed by the conveyor belt mechanism 2, the conveyor belt mechanism 2 is cleaned by the support and cleaning mechanism 3. This solves the problem that the existing manufactured sand pushing device does not have the function of crushing, and after the manufactured sand pushing device finishes transporting, a large amount of manufactured sand powder will remain on the surface of the manufactured sand pushing device, which requires subsequent cleaning by the staff and affects the production efficiency of manufactured sand.
