Description

Technical Field

[0001] This invention belongs to the field of mixing technology, specifically a mobile cement mixing device. Background Technology

[0002] When highways are expanded, large amounts of concrete are typically needed for the construction of intersections and medians. Mobile cement mixing plants can be flexibly deployed in these locations to ensure timely concrete supply. If the highway expansion involves the repair of existing road surfaces, mobile mixing plants can be used to produce pavement concrete, ensuring the quality and strength of the pavement.

[0003] A patent application with publication number CN211842540U discloses a mobile cement mixing device for construction projects, including a supporting base plate. Sliding rollers are fixedly connected to the four corners of the lower surface of the supporting base plate. A push handle is fixedly connected to the middle of the left side of the supporting base plate. A water tank is fixedly connected to the left side of the upper surface of the supporting base plate, and a material box is fixedly connected to the right side of the upper surface of the water tank. This mobile cement mixing device for construction projects, through the cooperation of a mixing motor, a first mixing plate, a second mixing plate, a mixing tank, a storage tank, a water outlet pipe, and a material outlet pipe, enhances the overall mixing effect and saves the time required for mixing.

[0004] The above solution still has some problems in practical application. When using this mobile mixing device, because the mixing space of the mixing device is square, after a period of work, a certain amount of cement tends to accumulate in the corners inside the mixing device, especially in the corners of the square space.

[0017] Preferably, each of the baffles is fixedly connected to a sealing plate on the side near the mixing tank, and the side of the sealing plate facing the mixing tank is smooth.

[0018] Preferably, one of the baffles has a first groove on the side near the other baffle, and the other baffle has a sealing strip fixedly connected to the first groove at the position corresponding to the first groove, and the sealing strip is engaged with the first groove.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Example 1

[0042] like Figures 1 to 9As shown in the embodiment of the present invention, a mobile cement mixing device includes a base plate 1, a water tank 2 fixedly connected to the upper surface of the base plate 1, a support platform 3 provided on the upper surface of the water tank 2, two water pumps 31 provided on the upper surface of the support platform 3, a fixed box 4 fixedly connected to one side of the water tank 2, a feed inlet 41 provided on the upper surface of the fixed box 4, a mixing device provided inside the fixed box 4, the mixing device including a mixing tank 44 provided inside the fixed box 4, the two water pumps 31 being used to pump water from the water tank 2 into the mixing tank 44; the mixing tank 44 being fixedly connected to the fixed box 4; a mixing paddle 46 rotatably disposed inside the mixing tank 44, one end of the mixing paddle 46 being fixedly connected to a second motor 45; and a partition 47 provided in the middle of the fixed box 4, a rotating assembly provided at the end of the partition 47 near the output end of the first hydraulic cylinder 5, the rotating assembly including two third motors 45 fixedly connected above the partition 47. 10. One of the third motors 410 has a rotating gear 417 connected to its output end; the output ends of both third motors 410 are fixedly connected to a first gear 411, and each first gear 411 is meshed with a rack plate 418. The rack plate 418 is slidably disposed on the top wall of the fixed box 4. Each rack plate 418 has a baffle plate 49 fixedly connected to the side away from the first gear 411. Each baffle plate 49 is semi-circular. A first hydraulic cylinder 5 is fixedly connected to the lower surface of the partition plate 47. A positioning rod 51 is fixedly connected to the output end of the first hydraulic cylinder 5. A rotating disk 52 is rotatably disposed at the top of the positioning rod 51. Several gear teeth 54 are fixedly connected to the circumferential surface of the rotating disk 52. The several gear teeth 54 mesh with the rotating gear 417. Several cleaning rollers 53 are rotatably connected to one side of the rotating disk 52. Several steel brush strips 59 are fixedly connected to the circumferential surface of each cleaning roller 53.

[0043] Specifically, when using this mobile mixing device, because the mixing space of the mixing device is square, after a period of operation, a certain amount of cement tends to accumulate in the corners inside the mixing device, especially in the corners of the square space. Once the cement hardens, it becomes difficult to clean. Therefore, this invention first changed the mixing space to a cylindrical mixing tank 44. However, regardless of whether it is the mixing tank 44 or the rectangular mixing space, a small amount of cement will continuously accumulate in the tank or rectangular mixing space after long-term use. This continuous accumulation gradually reduces the mixing space and the amount of cement mixed each time will decrease, affecting the use.

[0044] Therefore, this invention cleans the inner wall of the mixing tank 44 by setting a rotating disk 52 and several cleaning rollers 53 rotatably connected to one side of the rotating disk 52. Firstly, when constructing a median strip on a highway, cement needs to be poured into the median strip. Workers push the mobile mixing device to the work site, and then add various raw materials to be mixed into cement into the feed inlet 41 on the upper surface of the fixed box 4. The raw materials enter the mixing tank 44 along the feed inlet 41. After all the raw materials are added, two water pumps 31 are started to pump water from the water tank 2 into the mixing tank 44. Simultaneously, the second motor 45 is started, which drives the mixing paddle 46 fixed to its output end. The mixing paddle 46 continuously mixes the cement raw materials and water to form cement, which is then poured at the corresponding location. After the pouring at that location is completed, if there is no new pouring work, the inside of the mixing tank 44 needs to be cleaned. However, one end of the mixing tank 44 must first be opened to allow the cleaning roller 53 to be placed inside. By starting the two third motors 410, the first teeth fixed to the output ends of the two third motors 410 are driven. The first gear 411 drives the rack plate 418 that is slidably mounted on the top wall of the fixed box 4. The rack plate 418 pulls the baffle 49 fixed to each rack plate 418. The two baffles 49 seal one end of the mixing tank 44. After it is opened, the first hydraulic cylinder 5 is activated to drive the positioning rod 51 fixed to its output end to move towards the open end of the mixing tank 44. This achieves the effect of moving the rotating disk 52 into the mixing tank 44. The positioning rod 51 will carry the rotating disk 52 into the mixing tank 44. Then the rotating disk 52 and the mixing tank 44 rotate. The dynamic seal is used, and the cleaning roller 53, which is rotated and set on one side of the rotating disk 52, is in close contact with the inner wall of the mixing tank 44. A number of steel brush strips 59 are fixed on the circumference of the cleaning roller 53 to clean the cement that has solidified on the inner wall of the mixing tank 44. In order to clean more thoroughly, the water pump 31 also injects water into the mixing tank 44 while the cleaning roller 53 is cleaning, so that the residual cement will not solidify again during cleaning. This solves the problem that a small amount of cement will accumulate in the tank or rectangular mixing space over a long period of use, and the mixing space will gradually shrink due to the continuous accumulation.

[0045] like Figure 9 As shown, the interior of each cleaning roller 53 is hollow, and several through water spray holes 510 are opened on the circumferential surface of each cleaning roller 53. A rotating tube 55 is fixedly connected to the side of the positioning rod 51 away from the rotating disk 52. A flexible hose 56 is rotatably connected inside the rotating tube 55. The end of the flexible hose 56 away from the rotating tube 55 is fixedly connected to the water tank 2.

[0046] Specifically, when the rotating disc 52 is cleaning the inner wall of the mixing tank 44, if water is directly added to the mixing tank 44 through the water pump 31, the water cannot be completely sprayed onto the inner wall of the mixing tank 44, thus preventing the cleaning roller 53 from cleaning the inner wall of the mixing tank 44 effectively. Therefore, a flexible hose 56 is rotatably connected to one side of the rotating disc 52. The flexible hose 56 is connected to the water tank 2. When the rotating roller is cleaning the inner wall of the mixing tank 44, the water in the flexible hose 56 will continuously inject water into each cleaning roller 53. Then, the water will be sprayed out from the spray hole 510 of the cleaning roller 53, thereby achieving better cleaning of the inner wall of the mixing tank 44.

[0047] like Figure 5 and Figure 9 As shown, a convex ring 57 is fixedly connected to the side of the rotating disk 52 near the cleaning roller 53, and an annular groove 58 is opened in the mixing tank 44 corresponding to the position of the convex ring 57, and the convex ring 57 is engaged with the annular groove 58.

[0048] Specifically, after the rotating disc 52 comes into contact with the mixing tank 44, in order to ensure the sealing of the tank and prevent the water inside from flowing out, a convex ring 57 is provided on one side of the rotating disc 52. The convex ring 57 is engaged in the corresponding annular groove 58 of the mixing tank 44 to achieve a better cleaning effect, while also protecting the equipment outside the tank and preventing water from flowing out.

[0049] like Figure 8 As shown, a connecting rod 419 is fixedly connected to the upper surface of each rack plate 418, and a slider 423 is fixedly connected to the upper surface of each connecting rod 419. A groove is provided on the top wall of the fixed box 4 corresponding to the position of the slider 423, and the slider 423 slides in the groove.

[0050] Specifically, after the first gear 411 drives the rack plate 418 to rotate, a connecting rod 419 is fixedly connected to the upper surface of each rack plate 418, and a slider 423 is fixedly connected to the upper surface of the connecting rod 419. After the rack plate 418 moves, it will drive the slider 423 to slide in the groove opened in the top wall of the fixed box 4, thereby opening the two baffles 49, and then the cleaning roller 53 is moved into the stirring roller.

[0051] like Figure 7 As shown, the rack plate 418 is divided into a rack section and a rackless section. The rack section of the rack plate 418 is made of magnetic material. The fixing box 4 has a second groove 424 at the end of the rack plate 418. Electro-permanent magnet blocks are fixed to both sides of the inner wall of the second groove 424.

[0052] Specifically, when the rack plate 418 moves, after the rack segment of the rack plate 418 meshes with the first gear 411, it will be attracted to the electro-permanent magnet block set at the position of the rack plate 418 in the fixed box 4. Then, the first gear 411 will rotate freely on the rackless segment of the rack plate 418. After the cleaning roller 53 in the rotating disk 52 cleans and moves out of the mixing tank 44, the electro-permanent magnet block is activated to flip the magnetic pole, causing the electro-permanent magnet block to repel the rack segment of the rack plate 418, squeezing the rack plate 418 back to reset it. Then, the rotating disk 52 can be driven into the mixing tank 44 by the first hydraulic cylinder 5.

[0053] like Figure 8 As shown, each baffle 49 is fixed with a sealing plate 420 on the side near the mixing tank 44, and the side of the sealing plate 420 facing the mixing tank 44 is smooth.

[0054] Specifically, when using the baffle 49 to seal one end of the mixing tank 44, in order to maintain a better seal, a sealing plate 420 is fixed to the side of the baffle 49 near the mixing tank 44. This side of the sealing plate 420 is a smooth surface, which reduces cement adhesion to the sealing plate 420, thereby increasing the weight of the baffle 49 and facilitating the movement of the baffle 49 during the subsequent opening process.

[0055] like Figure 8 As shown, one of the baffles 49 has a first groove 421 on the side near the other baffle 49, and the other baffle 49 has a sealing strip 422 fixedly connected to the position corresponding to the first groove 421, and the sealing strip 422 is engaged with the first groove 421.

[0056] Specifically, when resetting the baffle 49, in order to maintain the sealing of the baffle 49 to the inside of the mixing tank 44, a first groove 421 is provided on one side of the baffle 49 near the other baffle 49, and a sealing strip 422 is fixed to the other baffle 49 at the position corresponding to the first groove 421. The sealing strip 422 is made of rubber, which can increase the friction between the two baffles 49 to a certain extent, thereby allowing the baffle 49 to also provide better sealing to the mixing tank 44.

[0057] Example 2

[0058] like Figures 1 to 9As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the rotating assembly further includes a second gear 412 fixedly connected to the output end of the water pump 31, the second gear 412 meshing with a strip steel 413, the end of the strip steel 413 away from the second gear 412 meshing with an auxiliary gear 414, the partition 47 being fixedly connected to a positioning plate 416 corresponding to the position of the auxiliary gear 414, the top end of the positioning plate 416 being rotatably connected to a rotating shaft 415, the auxiliary gear 414 being fixedly connected to the rotating shaft 415, and the rotating gear 417 being fixedly connected to the top end of the rotating shaft 415.

[0059] Specifically, when using the rotating assembly to drive the rotating disk 52 to rotate, one of the third motors 410 is first started. After the third motor 410 rotates, it will drive the first gear 411 and the second gear 412 fixed at its output end. The rotation of the first gear 411 will drive the rack plate 418 to rotate. The second gear 412, which rotates synchronously, will drive the strip steel 413 to rotate. The strip steel 413 will drive the auxiliary gear 414 to rotate. The auxiliary gear 414 will drive the rotating gear 417 fixed on the same rotating shaft 415 to rotate. When the first gear 411 just rotates to the rackless section of the rack plate 418, the third motor 410 stops. At this time, the rotating gear 417 meshes with the gear teeth 54 on the circumferential surface of the rotating disk 52, achieving the effect of driving the rotating disk 52 to rotate.

[0060] like Figure 2 As shown, a discharge pipe 42 is provided on one side of the fixed box 4. A connecting pipe 48 is fixedly connected to one end of the discharge pipe 42. The connecting pipe 48 is fixedly connected to the bottom end of the mixing tank 44. A valve 43 is fixedly connected to the circumferential surface of the discharge pipe 42. The valve 43 is used to pour cement.

[0061] Specifically, after the cement is mixed in the mixing tank 44, when it is needed, the valve 43 on the fixed box side is opened, so that the cement in the mixing tank 44 will flow out from the storage pipe along the connecting pipe 48, thereby better mixing the cement in the mixing tank 44.

[0062] like Figure 1 As shown, a rotating cover 21 is rotatably connected to the upper surface of the water tank 2, and a water pump 31 is fixedly connected to the output end of the water pump 31. The end of the water pump 32 away from the water pump 31 is fixedly connected to the water tank 2. The output end of the water pump 31 is also fixedly connected to the inlet pipe 33. The end of the inlet pipe 33 away from the output end of the water pump 31 is fixedly connected to the mixing tank 44.

[0063] Specifically, when using water tank 2, if the water in water tank 2 is insufficient, water can be added to water tank 2 by opening the rotating cover 21 on water tank 2, so that the mobile mixing device can be used again without having to continuously add water by connecting a tap. This allows for cement pouring in areas without taps during highway expansion.

[0064] The working principle is as follows: When using this mobile mixing device, because the mixing space is square, after a period of operation, cement tends to accumulate in the corners of the mixing device, especially in the corners of the square space. Once the cement hardens, it becomes difficult to clean. Therefore, this invention first changed the mixing space to a cylindrical mixing tank. However, regardless of whether it is a mixing tank or a rectangular mixing space, a small amount of cement will continue to accumulate in the tank or rectangular mixing space after long-term use. This continuous accumulation gradually reduces the mixing space and the amount of cement mixed each time, thereby increasing the number of times workers need to mix, increasing the labor force of workers, and consuming a lot of time, leading to the problem of extending the highway expansion time.

[0065] Therefore, this invention cleans the inner wall of the mixing tank 44 by setting a rotating disk 52 and several cleaning rollers 53 rotatably connected to one side of the rotating disk 52. Firstly, when constructing a median strip on a highway, and when pouring cement for the median strip, workers push the mobile mixing device to the work site. Then, various raw materials to be mixed into cement are added to the feed inlet 41 on the upper surface of the fixed box 4. The raw materials enter the mixing tank 44 along the feed inlet 41. After the raw materials are mixed, two water pumps 31 are started to pump water from the water tank 2 into the mixing tank 44. Simultaneously with the start of the water pumps 31, a second motor 45 is started. The second motor 45 drives the mixing paddle 46 fixed to its output end. Under continuous stirring, the mixing paddle 46 fully mixes the cement raw materials with water to form... Cement is poured, and then the corresponding location is poured. After the pouring is completed at that location, if there is no new pouring work, the inside of the mixing tank 44 needs to be cleaned. By starting the first hydraulic cylinder 5, the positioning rod 51 fixed to its output end is moved towards the open end of the mixing tank 44. The positioning rod 51 will carry the rotating disk 52 into the mixing tank 44, and then the rotating disk 52 and the mixing tank 44 will rotate and seal. At the same time, the cleaning roller 53, which is rotated and set on one side of the rotating disk 52, is in close contact with the inner wall of the mixing tank 44, and many steel brush strips 59 are fixed on the circumference of the cleaning roller 53 to clean the cement that has hardened on the inner wall of the mixing tank 44. In order to clean more thoroughly, one of the third motors 410 is started. After the third motor 410 rotates, it will drive The first gear 411 and the second gear 412 are fixed to its output end. The rotation of the first gear 411 will drive the rack plate 418 to rotate. The second gear 412, which rotates synchronously, will drive the strip steel 413 to rotate. The strip steel 413 will drive the auxiliary gear 414 to rotate. The auxiliary gear 414 will drive the rotating gear 417 fixed to the same rotating shaft 415 to rotate. When the first gear 411 just rotates to the rackless section of the rack plate 418, the third motor 410 stops. At this time, the rotating gear 417 meshes with the gear teeth 54 on the circumferential surface of the moving rotating disk 52, achieving the effect of driving the rotating disk 52 to rotate. When the rotating disk 52 rotates to clean the inner wall of the mixing tank 44, if the water is directly pumped into the mixing tank by the water pump 31... Adding water to the mixing tank 44 would prevent the water from being fully sprayed onto the inner wall of the mixing tank 44, thus hindering the cleaning roller 53 from effectively cleaning the inner wall of the mixing tank 44. Therefore, a flexible hose 56 is rotatably connected to one side of the rotating disc 52. The flexible hose 56 is connected to the water tank 2. When the rotating roller cleans the inner wall of the mixing tank 44, the water in the flexible hose 56 continuously injects water into each cleaning roller 53. Then, the water is sprayed out from the spray holes 510 of the cleaning roller 53, thereby achieving better cleaning of the inner wall of the mixing tank 44. This prevents residual cement from hardening again during cleaning and solves the problem of small amounts of cement accumulating in the tank or rectangular mixing space over a long period of use. This continuous accumulation gradually reduces the mixing space and the amount of cement mixed each time.This increases the number of times workers need to mix the materials, thus increasing their workload and consuming a significant amount of time, ultimately prolonging the highway expansion project.

[0066] When using the rotating disc 52, one end of the mixing tank 44 must first be opened before the cleaning roller 53 can be placed into the mixing tank 44. By starting the two third motors 410, the first gears 411 fixed to the output ends of the two third motors 410 are driven. Then the first gears 411 drive the rack plates 418 that are slidably set on the top wall of the fixed box 4. The rack plates 418 pull the baffles 49 fixed to each rack plate 418. The two baffles 49 seal one end of the mixing tank 44. After pulling it open, the rotating disc 52 can be moved into the mixing tank 44.

[0067] After cleaning is completed, water is added to the water tank 2 by opening the rotating cover 21 on the water tank 2, so that the mobile mixing device can be used again without the need for continuous water supply via a tap.
