Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to cleaning equipment for a concrete mixing device. Background Art

[0002] Concrete is a mixture of cementitious materials, aggregates, and water mixed in appropriate proportions. It is an artificial stone formed after a certain period of time. Concrete is widely used in civil engineering. A concrete mixer is a machine that mixes cement, sand and gravel aggregates, and water to make a concrete mixture. During discharge, some concrete will remain in the mixing device. If this concrete is not removed in time, it will gradually accumulate and eventually form lumps, increasing the resistance of the machine operation and may even cause damage to the machine.

The wheels slidably mounted on the bottom of the body in this utility model more effectively enhance the flexibility of the concrete mixer, making installation and use more convenient.

[0004] However, the above technical solution will generate a large amount of dust when cleaning the concrete mixing device, and the above method is not convenient for handling the dust. After the dust floats out of the mixing device, it may affect the environment and the health of the operators. Therefore, we propose a cleaning device for a concrete mixing device to solve the above problem. Utility Model Content

[0022] Example:

[0023] See also Figures 1 to 3 The utility model provides a technical solution for a cleaning device for a concrete mixing device: comprising a base plate 1, a mounting frame 5 for providing support is fixedly connected to the top of the base plate 1, a mixing barrel 6 for mixing concrete is rotatably connected to the inner cavity of the mounting frame 5 through a bearing, and a cleaning structure for cleaning the interior of the mixing barrel 6 is movably connected to the inner cavity of the mixing barrel 6;

[0024] The cleaning structure includes a support rod 12, the bottom end of the support rod 12 is connected to a mounting plate 13, and the mounting plate 13 is detachably connected to the top of the bottom plate 1 by bolts, and the side wall of the support rod 12 is fixedly connected to a threaded rod 14, and the outer surface of the threaded rod 14 is detachably connected to a plurality of nuts 15 for limiting by threads, and the outer surface of the threaded rod 14 is slidably connected to a connecting frame 16, and the connecting frame 16 is located between the two nuts 15. By removing the nuts 15, the connecting frame 16 can be disassembled, and the top of the connecting frame 16 is detachably connected to a connecting block 17 through an angle code, and the top of the connecting block 17 is fixedly connected to a connecting ring 18, and one side of the connecting block 17 is fixedly connected to a joint 21 for connecting a water pipe, and water supply to the inside of the connecting ring 18 can be facilitated through the joint 21. A baffle 19 is fixedly connected to one side of the connecting ring 18, and one side of the connecting ring 18 is located on the periphery of the baffle 19 and is equidistantly distributed in a ring shape, and the water outlet end of the nozzle 20 is located above the baffle 19.

[0025] A limiting rod 22 is fixedly connected to one side of the connecting frame 16. The limiting rod 22 is set to a "T" shape. A connecting plate 23 is sleeved on the outer surface of the limiting rod 22. A scraper 27 for scraping concrete attached to the inner wall of the mixing barrel 6 is fixedly connected between the two connecting plates 23.

[0026] The outer wall of the scraper 27 is fixedly connected to a connecting rod 28 , and the outer wall of the connecting rod 28 is fixedly connected to a wire brush 29 for cleaning concrete attached to the inner wall of the mixing barrel 6 , and the wire brush 29 is composed of a plurality of rectangular and equidistantly distributed steel wires.

[0027] A through slot 2 is provided through the top of the base plate 1, and a connecting slot 4 is provided through the side wall of the base plate 1 to the inner cavity of the through slot 2. The inner cavity of the through slot 2 is movably connected to a bracket 3 for providing support force to the whole. A number of adjustment slots of the same size as the connecting slot 4 are axially equidistantly provided through the side wall of the bracket 3 to facilitate adjustment of the overall height of the device.

[0028] A mounting base 7 is fixedly connected to the top of the base plate 1 and located on one side of the mixing barrel 6. The inner cavity of the mounting base 7 is rotatably connected to a shaft 8. The outer surface of the shaft 8 is sleeved with a gear 10. One end of the shaft 8 is connected to a pulley 9. The outer surface of the mixing barrel 6 is sleeved with a gear ring 11, and the gear ring 11 is engaged with the gear 10.

[0029] Specifically, an external machine drives the shaft 8 to rotate through the pulley 9, and the shaft 8 drives the gear 10 to rotate. The gear 10 drives the mixing barrel 6 to rotate in the mounting frame 5 through the gear ring 11 to complete the mixing of the concrete.

[0030] A buffer groove 24 is provided on one side of the connecting plate 23, and one end of the buffer groove 24 is fixedly connected to a limiting ring 25. The limiting rod 22 is slidably connected to the limiting ring 25. The limiting rod 22 can be limited in the connecting plate 23 through the limiting ring 25 to prevent the connecting plate 23 from falling off. A buffer spring 26 is connected to the inner cavity of the buffer groove 24 and located on one side of the limiting rod 22.

[0031] The working principle of this utility model is:

[0032] When the mixing barrel 6 needs to be cleaned, the gear ring 11 is first driven to rotate by the gear 10, and the gear ring 11 drives the mixing barrel 6 to rotate. Since the scraper 27 is located inside the mixing barrel 6 and the side wall of the scraper 27 is in contact with the inner wall of the mixing barrel 6, when the mixing barrel 6 rotates, the concrete attached to the inner wall will be scraped off by the scraper 27.

[0033] When cleaning the mixing barrel 6, the external water pipe is connected to the side wall of the connecting block 17 through the joint 21. At this time, the water in the connecting ring 18 can be supplied and purified. The water in the connecting ring 18 is discharged through the nozzle 20 and is discharged by the nozzle 20. Figure 1 As shown, the connecting ring 18 is located at the port of the mixing barrel 6. When the nozzle 20 discharges water, the continuously flowing water forms a water net at the port of the mixing barrel 6. At this time, the dust generated when cleaning the mixing barrel 6 will be absorbed by the water net and flow into the mixing barrel 6 along the inner wall of the mixing barrel 6 to clean the mixing barrel 6.

[0034] Since there is a certain distance between the multiple nozzles 20, the discharged water will flow out in a linear shape. In order to avoid the gap between the water network being too large, which will affect the dust collection rate, a baffle 19 is fixed on one side of the connecting ring 18, and Figure 2 It can be seen that the baffle 19 is arc-shaped. When water is sprayed from the nozzle 20, it will flow above the baffle 19. At this time, the linear water flow will be dispersed by the baffle 19 and slide down along the edge of the baffle 19 to form a water curtain, which expands the dust collection range and further improves the dust reduction effect.

[0035] In order to avoid affecting the discharge of the mixing barrel 6, Figure 1 As shown, the connecting ring 18 is located above the end of the mixing barrel 6;

[0036] Since the scraper 27 needs to be in close contact with the mixing barrel 6 when working, in order to prevent the scraper 27 from having a gap with the inner wall of the mixing barrel 6 due to wear during long-term working, resulting in incomplete cleaning, the present device provides a supporting force to the connecting plate 23 through the buffer spring 26 when in use. Under the action of the buffer spring 26, it can ensure that the edge of the scraper 27 can always be in close contact with the inner wall of the mixing barrel 6, thereby ensuring that the scraper 27 can scrape the concrete attached to the mixing barrel 6. In addition, in special circumstances such as when the device vibrates, the scraper 27 can drive the connecting plate 23 to compress the buffer spring 26 to provide a buffer distance, thereby preventing the scraper 27 from being damaged due to rigid impact.

[0037] And because the wire brush 29 is fixedly connected to the outer wall of the scraper 27 through the connecting rod 28, when the mixing barrel 6 rotates, the wire brush 29 can clean the inner wall of the mixing barrel 6, avoiding impurities such as sand and gravel that are difficult to scrape off by the scraper 27 from remaining in the mixing barrel 6 after cleaning, thereby improving the cleaning effect.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
