Sand and stone sorting and cleaning all-in-one machine for civil engineering

Abstract

This invention discloses an integrated sand and gravel sorting and cleaning machine for civil engineering, including an outer casing. In this invention, a vibrator is fixedly connected to the bottom end of the outer casing, and a motor is fixedly connected to the bottom end of the inner wall of the outer casing. A hollow shaft extends from the upper end of the motor, and two sets of hollow rotating rods are fixedly connected to the cylindrical outer surface of the hollow shaft, with the hollow shaft communicating with the hollow rotating rods. Each set of hollow rotating rods has brush bristles at its lower end. The motor drives the hollow rotating rods to rotate via the hollow shaft. The rotation of the hollow rotating rods disperses the sand and gravel as much as possible, preventing sand and gravel accumulation and reducing separation efficiency. Similarly, it also prevents sand and gravel accumulation on the fine filter screen. The brush bristles clean the perforations on the coarse and fine filter screens, preventing clogging. Simultaneously, when the regulating valve is opened, water is sprayed through the nozzles to clean the coarse and fine filter screens. The regulating valve can also be opened slightly, and the small water flow from the nozzles can further clean the sand and gravel, preventing dust from splashing during sand screening.

Description

Technical Field

[0001] This invention relates to the field of sand and gravel screening, and more particularly to an integrated sand and gravel sorting and cleaning machine for civil engineering. Background Technology

[0002] As one of the most basic building materials in civil engineering construction, the quality of sand and gravel directly affects the strength of concrete and the durability of engineering structures. During the mining and transportation process, natural sand and gravel often have a large amount of impurities such as mud and dust attached to their surfaces, and the particle size distribution of the sand and gravel is uneven. If used directly in construction, it will seriously affect the mixing quality of concrete and the safety of the project. Existing sand and gravel sorting methods can only simply screen sand and gravel of different sizes, and cannot clean the dust on the surface of the sand and gravel. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated sand and gravel sorting and cleaning machine for civil engineering.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a sand and gravel sorting and cleaning integrated machine for civil engineering, comprising an outer sleeve, a vibrator fixedly connected to the bottom end of the outer sleeve, a motor fixedly connected to the bottom end of the inner wall of the outer sleeve, a hollow shaft extending from the upper end of the motor, two sets of hollow rotating rods fixedly connected to the cylindrical outer surface of the hollow shaft, and the hollow shaft communicating with the hollow rotating rods, each set of hollow rotating rods having bristles at the lower end, and multiple sets of nozzles at the lower end of the hollow rotating rods, a support rod fixedly connected to the top end of the inner wall of the outer sleeve, a connecting sleeve fixedly connected to the upper end of the support rod, and the hollow shaft rotatably connected to the connecting sleeve, a coarse filter screen fixedly connected to the inner wall of the outer sleeve, and a fine filter screen fixedly connected to the inner wall of the outer sleeve, with the coarse filter screen and the fine filter screen respectively located directly below a set of hollow rotating rods.

[0005] As a further description of the above technical solution:

[0006] The inner wall of the outer sleeve is fixedly connected to a first funnel, which is located above the coarse filter screen. The inner wall of the outer sleeve is fixedly connected to a second funnel, which is located below the coarse filter screen. The inner wall of the outer sleeve is fixedly connected to an inclined plate, which is located below the fine filter screen.

[0007] As a further description of the above technical solution:

[0008] A first discharge pipe is fixedly connected to the cylindrical outer surface of the outer sleeve. A first notch is provided on one side of the coarse filter screen, and the first discharge pipe corresponds to the position of the first notch. A second discharge pipe is fixedly connected to the cylindrical outer surface of the outer sleeve. A second notch is provided on one side of the fine filter screen, and the second notch corresponds to the position of the second discharge pipe.

[0009] As a further description of the above technical solution:

[0010] A flexible hose is fixedly connected to the upper end of the connecting sleeve, and an adjusting valve is provided on the flexible hose.

[0011] As a further description of the above technical solution:

[0012] The lower end of the outer sleeve is fixedly connected to multiple sets of elastic ribs, and the lower ends of the multiple sets of elastic ribs are fixedly connected to a base plate.

[0013] The present invention has the following beneficial effects:

[0014] 1. This invention utilizes a motor that drives a hollow rotating rod via a hollow shaft. The rotation of the hollow rotating rod disperses the sand and gravel as much as possible, preventing sand and gravel accumulation and reducing separation efficiency. Similarly, it also prevents sand and gravel accumulation on the fine filter screen. The brush bristles clean the perforations on both the coarse and fine filter screens, preventing them from becoming clogged. Simultaneously, when the regulating valve is opened, water is sprayed through the nozzle to clean the coarse and fine filter screens. The regulating valve can also be opened slightly, and the small amount of water from the nozzle can further clean the sand and gravel, preventing dust from splashing during sand screening (since the sand and gravel will be mixed with cement later, a small amount of water has no impact on subsequent processes).

[0023] Reference Figure 1-6 An embodiment of the present invention provides a sand and gravel sorting and cleaning integrated machine for civil engineering, comprising an outer sleeve 1, a vibrator 11 fixedly connected to the bottom end of the outer sleeve 1, a motor 17 fixedly connected to the bottom end of the inner wall of the outer sleeve 1, a hollow shaft 18 extending from the upper end of the motor 17, two sets of hollow rotating rods 21 fixedly connected to the cylindrical outer surface of the hollow shaft 18, and the hollow shaft 18 communicating with the hollow rotating rods 21, each set of hollow rotating rods 21 having bristles 22 at the lower end, and multiple sets of nozzles 23 at the lower end of the hollow rotating rods 21, a support rod 7 fixedly connected to the top end of the inner wall of the outer sleeve 1, a connecting sleeve 8 fixedly connected to the upper end of the support rod 7, and the hollow shaft 18 and the connecting sleeve 8 rotating... The outer sleeve 1 is connected to a coarse filter screen 13 and a fine filter screen 15. The coarse filter screen 13 and the fine filter screen 15 are respectively located directly below a set of hollow rotating rods 21. The vibrator 11 can make the outer sleeve 1 vibrate as a whole, pouring sand and gravel into the upper part of the outer sleeve 1. The first funnel 12 concentrates the sand and gravel in the middle of the coarse filter screen 13. The motor 17 is started, and the hollow shaft 18 drives the hollow rotating rods 21 to rotate. The rotation of the hollow rotating rods 21 can disperse the sand and gravel as much as possible, preventing the sand and gravel from accumulating and reducing the separation efficiency. Similarly, it can also prevent the sand and gravel from accumulating on the fine filter screen 15. The brush bristles 22 can clean the holes on the coarse filter screen 13 and the fine filter screen 15 to prevent the holes from becoming blocked.

[0024] The inner wall of the outer sleeve 1 is fixedly connected to a first funnel 12, which is located above the coarse filter screen 13. The inner wall of the outer sleeve 1 is fixedly connected to a second funnel 14, which is located below the coarse filter screen 13. The inner wall of the outer sleeve 1 is fixedly connected to an inclined plate 16, which is located below the fine filter screen 15.

[0025] A first discharge pipe 4 is fixedly connected to the cylindrical outer surface of the outer sleeve 1. A first notch 19 is provided on one side of the coarse filter screen 13, and the first discharge pipe 4 corresponds to the first notch 19. A second discharge pipe 5 is fixedly connected to the cylindrical outer surface of the outer sleeve 1. A second notch 20 is provided on one side of the fine filter screen 15, and the second notch 20 corresponds to the second discharge pipe 5.

[0026] A flexible hose 9 is fixedly connected to the upper end of the connecting sleeve 8, and an adjusting valve 10 is provided on the flexible hose 9; multiple sets of elastic ribs 3 are fixedly connected to the lower end of the outer sleeve 1, and a base plate 2 is fixedly connected to the lower end of the multiple sets of elastic ribs 3.

[0027] Working principle: Connect hose 9 to the water supply pipe (faucet). Initially, regulating valve 10 is slightly open. Start vibrator 11 to vibrate the entire outer sleeve 1, allowing sand and gravel to be poured in from above. The first funnel 12 concentrates the sand and gravel in the middle of the coarse filter screen 13. Start motor 17, and hollow shaft 18 drives hollow rotating rod 21 to rotate. The rotation of hollow rotating rod 21 disperses the sand and gravel as much as possible, preventing sand and gravel accumulation and reducing separation efficiency. Similarly, it also prevents sand and gravel accumulation on fine filter screen 15. Brush bristles 22 clean the holes on coarse and fine filter screens 13 and 15 to prevent clogging. Fine sand of different particle sizes is separated. Do not discharge from the first discharge pipe 4, the second discharge pipe 5, or the third discharge pipe 6. When cleaning is required, simply open the regulating valve 10, and the nozzle 23 will spray water onto the upper surfaces of the coarse filter screen 13 and the fine filter screen 15. The brush 22 can clean the surfaces of the coarse filter screen 13 and the fine filter screen 15, completing the self-cleaning process. During the sand screening process, the small amount of water flow from the nozzle 23 cannot prevent dust from splashing during sand screening (the sand and gravel will be mixed with cement later, and a small amount of water will not affect the subsequent project). The larger particles of impurities are separated from the first discharge pipe 4, the compliant sand and gravel are separated from the second discharge pipe 5, and the mud and dust are discharged from the hose 9.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
