[0018] Please see Figure 1-4This utility model provides a technical solution: a concrete additive production equipment, including a machine body 1 and a mixing cylinder 2. The machine body 1 is connected to the mixing cylinder 2. The machine body 1 is the driving body of a three-dimensional mixer in the prior art, which can drive the mixing cylinder 2 to rotate. Both the machine body 1 and the mixing cylinder 2 are existing equipment. The mixing cylinder 2 is provided with a cleaning structure for cleaning the inner wall of the mixing cylinder 2. The cleaning structure includes two clamping units 3 for fixing the cleaning structure to the mixing cylinder 2, a water spraying unit 5 for spraying external water source onto the inner wall of the mixing cylinder 2, and a driving unit 4 for driving the water spraying unit 5 to rotate. The two clamping units 3 are detachably set on the top of the mixing cylinder 2, and the two clamping units 3 are arranged symmetrically on the left and right. The driving unit 4 is fixedly set on the top of the two clamping units 3. The water spraying unit 5 is connected to the driving unit 4.

[0019] Specifically, the clamping unit 3 includes a clamping frame 31, a cylinder 32, and a clamping plate 33. The clamping frame 31 is movably disposed on the top of the mixing cylinder 2. The clamping frame 31 has an inverted concave structure. The parts of the clamping frame 31 that contact the side wall of the mixing cylinder 2 are all matched with the side wall of the mixing cylinder 2. The cylinder 32 is fixedly disposed on the outside of the clamping frame 31, and the driving end of the cylinder 32 moves through the outside of the clamping frame 31. The clamping plate 33 is fixedly disposed on the driving end of the cylinder 32, and the clamping plate 33 abuts against the outer wall of the mixing cylinder 2.

[0020] When installing the clamping unit 3, open the cover of the mixing cylinder 2, then put the clamping frame 31 on the top of the mixing cylinder 2, and then turn on the cylinder 32 so that the driving end of the cylinder 32 drives the clamping plate 33 to move towards the outer wall of the mixing cylinder 2 until the clamping plate 33 is completely against the outer wall of the mixing cylinder 2.

[0021] Specifically, the drive unit 4 includes a support box 41, an annular guide rail 42, two sliders 43, a first gear 44, a first motor 45, a drive shaft 46, and a second gear 47. The support box 41 is fixedly mounted on the top of the clamping frame 31. The annular guide rail 42 is fixedly mounted on the bottom of the support box 41. The two sliders 43 are slidably connected to the annular guide rail 42, allowing the sliders 43 to slide circularly within the annular guide rail 42. The first gear 44 is fixedly mounted on the top of the two sliders 43, and the sliders 43 support the first gear 44. The first motor 45 is fixedly mounted on the top of the two sliders 43. The first motor 45 is located on the top of the support box 41, and its driving end extends through the top of the support box 41. The top end of the drive shaft 46 is fixedly connected to the driving end of the first motor 45, and the bottom end of the drive shaft 46 is rotatably connected to the bottom of the support box 41. The second gear 47 is fixedly mounted on the drive shaft 46. The driving end of the first motor 45 can drive the drive shaft 46 and the second gear 47 to rotate. The second gear 47 can drive the first gear 44, which meshes with it, to rotate. When the first gear 44 rotates, it can drive the slider 43 to rotate within the annular guide rail 42.

[0022] Specifically, the water spraying unit 5 includes a water spraying pipe 51, a water delivery pipe 52, and multiple nozzles 53. The water spraying pipe 51 is fixedly connected to the center of the first gear 44, and the water spraying pipe 51 movably passes through the top and bottom of the support box 41. The first motor 45 can transmit rotational power to the water spraying pipe 51 through the second gear 47 and the first gear 44, thereby causing it to rotate. The inner wall of the water spraying pipe 51 is connected to the water delivery pipe 52 through a sealed bearing. The outer ring of the sealed bearing is fixedly connected to the inner wall of the water spraying pipe 51, and the inner ring of the sealed bearing is interference-fitted with the outer wall of the water delivery pipe 52. The water delivery pipe 52 is in a fixed state, thereby delivering external water to the water spraying pipe 51. This structure allows the water spraying pipe 51 to rotate freely under the action of the drive unit 4. At the same time, the sealing mechanism inside the sealed bearing ensures that no leakage occurs during the water delivery process, thereby ensuring rotational flexibility while achieving a good sealing effect. Multiple nozzles 53 are fixedly installed on the water spraying pipe 51, and the nozzles 53 can spray water onto the inner wall of the mixing cylinder 2.

[0023] The drive unit 4 and the water spray unit 5 work synchronously. First, the external water pipe and the water supply pipe 52 are connected together by existing equipment such as threads, so that the water source is delivered to the water spray pipe 51 through the external water pipe and the water supply pipe 52, and then sprayed out through the nozzle 53 to wash the inner wall of the mixing drum 2. The first motor 45 in the drive unit 4 is turned on synchronously. When it starts, it will transmit the rotational power to the water spray pipe 51 through the second gear 47 and the first gear 44. The water spray pipe 51 will drive the nozzle 53 to rotate, thereby thoroughly washing all parts of the inner wall of the mixing drum 2.

[0024] Specifically, the water spray pipe 51 is also equipped with a brush cleaning unit 6 for further cleaning the inner wall of the mixing drum 2. The brush cleaning unit 6 works synchronously with the drive unit 4 and the water spray unit 5. The combination of the three can maximize the cleaning effect and reduce the cleaning time.

[0025] Specifically, the brush cleaning unit 6 includes two connecting plates 61, a brush roller 62, a support plate 63, and a second motor 64. The two connecting plates 61 are fixedly mounted on the water spray pipe 51. The brush roller 62 is rotatably connected to the two connecting plates 61. When the water spray pipe 51 rotates, it can drive the cleaning brush to rotate synchronously, thereby cleaning the inner wall of the mixing cylinder 2. The support plate 63 is fixedly mounted on the water spray pipe 51 and is located above the two connecting plates 61. The second motor 64 is fixedly mounted on the support plate 63, and the drive end of the second motor 64 is fixedly connected to the central axis of the brush roller 62. The second motor 64 is a motor with an internal battery, which can be charged before use.

[0026] The second motor 64 inside the brush cleaning unit 6 rotates synchronously with the water spray pipe 51 and can drive the brush roller 62 to rotate. While revolving with the water spray pipe 51, the brush roller 62 can also rotate on its own axis. This compound motion allows the brush roller 62 to contact the inner wall of the mixing cylinder 2 with a more complex and comprehensive trajectory, thereby significantly improving the cleaning effect, avoiding the cleaning blind spots that may be caused by rotation in one direction, and achieving a more thorough and efficient cleaning of the inner wall of the mixing cylinder 2.

[0027] Specifically, a scraper 7 is fixedly installed at the bottom of the water spray pipe 51. The scraper 7 rotates synchronously with the water spray pipe 51 to automatically clean the bottom of the mixing cylinder 2.

[0028] Specifically, a rubber pad 34 matching the shape of the outer wall of the mixing cylinder 2 is fixedly provided on the side of the clamping plate 33 near the outer wall of the mixing cylinder 2. The rubber pad 34 can improve the stability of the clamping unit 3.

[0029] Specifically, a support base 54 is fixedly installed on the top of the support box 41, and the support base 54 is fixedly connected to the water supply pipe 52. The support base 54 is used to fix the water supply pipe 52 and ensure the stability of the water supply pipe 52.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
