Abstract
Description
Technical Field
[0001] This utility model relates to the field of mortar mixing technology, and in particular to a mortar mixing device. Background Technology
[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and cementitious materials with water in a certain proportion. It is also called mortar or grout. The difference between building mortar and concrete is that building mortar does not contain coarse aggregate. It is made by mixing cementitious materials, fine aggregate, and water in a certain proportion. According to its use, it is divided into masonry mortar and plastering mortar; according to the different materials used, it is divided into cement mortar, lime mortar, gypsum mortar, and cement-lime mixed mortar, etc. The rational use of mortar plays an important role in saving cementitious materials, facilitating construction, and improving the quality of projects.
[0003] Existing mortars are mixed manually or by mechanical mixers. Sometimes, when the mixing shaft is in operation, some material that has not fully mixed with water will adhere to the connection between the mixing blades and the mixing shaft. The unmixed material is covered with a mortar film that has been mixed with water, making it impossible to remove during mixing. As a result, when the mortar is poured out, a large amount of unmixed mortar remains on the mixing shaft, wasting a lot of material. Utility Model Content
[0004] The purpose of this utility model is to solve the technical problems mentioned above, and to propose a mortar mixing device.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a mortar mixing device, comprising a base plate, on which two fixing plates are fixedly mounted, and rotating shafts are rotatably connected to the surfaces of the two fixing plates. A U-shaped seat is fixedly mounted between the two rotating shafts. Reciprocating devices are provided on the inner walls of both sides of the U-shaped seat. Each reciprocating device includes two sleeves, which are fixedly mounted on the inner walls of both sides of the U-shaped seat. Support rods are slidably connected inside each of the two sleeves, and a strip frame is fixedly mounted between the two support rods. The sleeves and support rods provide greater stability to the strip frame during movement.
[0006] Preferably, two L-shaped rods are fixedly installed on both sides of the strip frame. A mixing tank is fixedly installed at the end of each L-shaped rod away from the strip frame. A feed hopper is fixedly installed on the outer wall surface of the mixing tank, and a hopper cover is hinged to the surface of the feed hopper. A rotating rod is rotatably connected between the inner walls of the two sides of the mixing tank. Multiple mixing rods are distributed in a ring on the outer wall surface of the rotating rod. A first motor is fixedly installed on one end face of the mixing tank, and the output end of the first motor is fixedly connected to the rotating rod. The L-shaped rods serve to support the mixing tank.
[0007] Preferably, a vertical plate is fixedly mounted on the horizontal end surface of the U-shaped seat, and a second motor is fixedly mounted on the surface of the vertical plate. A special-shaped gear is fixedly mounted on the output end of the second motor. Only one-third of the teeth on the surface of the special-shaped gear are visible. The inner walls on both sides of the strip frame are provided with tooth-like structures, and the special-shaped gear meshes with the tooth-like structures on the inner walls of both sides of the strip frame. The second motor drives the special-shaped gear to rotate, and the special-shaped gear drives the strip frame to move.
[0008] Preferably, one of the fixed plates has a flipping device on its surface, the flipping device including a third motor, the third motor being fixedly mounted on the surface of one of the fixed plates, and the output end of the third motor being fixedly connected to one of the rotating shafts. The third motor drives the rotating shaft to rotate.
[0009] Preferably, one of the fixing plates has a vertical groove on its surface, and a sliding plate is slidably connected inside the vertical groove. A plug is fixedly installed on the surface of the sliding plate, and a plurality of insertion holes are annularly formed on the outer wall surface of one of the rotating shafts. The arrangement of the plug and insertion holes serves to restrict the rotation of the rotating shaft.
[0010] Preferably, a rectangular plate is fixedly mounted on the surface of one of the fixing plates, and a spring is fixedly mounted between the rectangular plate and the sliding plate. The spring serves to limit the position of the sliding plate inside the vertical groove.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0012] 1. In this utility model, by setting a reciprocating device, when the device is needed, firstly, the base plate is raised. After the raising is completed, the material is fed into the mixing tank from the feed hopper, and then water is injected into the mixing tank from the feed hopper. Finally, the hopper cover is closed, and then the first motor is started. The first motor drives the rotating rod to rotate, and the rotating rod drives the stirring rod to rotate. The rotating rod stirs the material and water inside the mixing tank. At the same time, during the stirring process, the second motor can be started. The second motor drives the shaped gear to rotate. When the shaped gear meshes with the tooth-like structure on the inner wall of the upper end of the strip frame, it causes the strip frame to move to the left. The leftward movement of the strip frame causes one of the support rods to move into the sleeve, and the other support rod moves out of the sleeve. Simultaneously, the leftward movement of the strip frame also causes the L-shaped rod to move to the left, which in turn causes the mixing drum to move to the left. When the shaped gear rotates and meshes with the toothed structure on the inner wall of the lower end of the strip frame, the strip frame will move to the right, thus ultimately causing the mixing drum to move to the right. As the shaped gear continues to rotate, the mixing drum moves back and forth, making the mortar inside the mixing drum more evenly mixed. Through the cooperation of the above structures, the liquid inside the mixing drum can repeatedly wash the mixing rod and rotating rod while the mixing drum is shaking left and right, washing off the unmixed mortar material adhering to the mixing rod and rotating rod, and fully mixing it with the liquid, improving the fluidity and water retention of the mortar, and saving a lot of mortar material.
[0013] 2. In this utility model, by setting a flipping device, when the mixing is complete and unloading is required, the sliding plate is first slid, causing it to move inside the vertical groove. The movement of the sliding plate inside the vertical groove compresses the spring, causing it to be compressed. Simultaneously, the movement of the sliding plate inside the vertical groove also drives the insertion rod to move, causing it to move out of the insertion hole. The separation of the insertion rod and the insertion hole causes one of the rotating shafts to lose its limit position. At this point, the third motor can be activated. The third motor starts, driving one of the rotating shafts to rotate. The rotation of one rotating shaft drives the U-shaped seat to rotate, and the rotation of the U-shaped seat drives the other... The rotating shaft rotates, and the U-shaped seat rotates simultaneously, ultimately driving the mixing drum to rotate. When the mixing drum rotates to the position where the feed hopper faces downwards, the third motor is turned off, and then the sliding plate is released. The spring's rebound force causes the insert rod to re-insert into the corresponding insertion hole, thereby re-restraining the rotation of one of the rotating shafts. Next, the collecting mechanism is placed below the feed hopper, and the hopper cover is opened. At this time, the mortar inside the mixing drum will flow from the feed hopper into the collecting mechanism. Through the cooperation of the above structures, the mixing drum can be flipped, making it easier for workers to unload the mortar and further improving the practicality of the device.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Please see Figures 1-4 This utility model provides a technical solution: a mortar mixing device, including a base plate 1, two fixing plates 2 are fixedly installed on the surface of the base plate 1, and a rotating shaft 3 is rotatably connected to the surface of each of the two fixing plates 2. A U-shaped seat 4 is fixedly installed between the two rotating shafts 3.
[0023] The specific configuration and function of its reciprocating device 5 and flipping device 6 will be explained in detail below.
[0024] In this embodiment: reciprocating devices 5 are provided on both inner wall surfaces of the U-shaped seat 4. The reciprocating devices 5 include two sleeves 51. The two sleeves 51 are fixedly installed on both inner wall surfaces of the U-shaped seat 4. Support rods 52 are slidably connected inside the two sleeves 51. A strip frame 53 is fixedly installed between the two support rods 52.
[0025] In this embodiment, the sleeve 51 and the support rod 52 are designed to make the strip frame 53 more stable when it moves.
[0026] Specifically, two L-shaped rods 54 are fixedly installed on both sides of the strip frame 53. A mixing tank 55 is fixedly installed at the end of each L-shaped rod 54 away from the strip frame 53. A feed hopper 7 is fixedly installed on the outer wall surface of the mixing tank 55. A hopper cover 8 is hinged to the surface of the feed hopper 7. A rotating rod 9 is rotatably connected between the inner walls of the two sides of the mixing tank 55. Multiple stirring rods 10 are distributed in a ring on the outer wall surface of the rotating rod 9. A first motor 11 is fixedly installed on one end face of the mixing tank 55. The output end of the first motor 11 is fixedly connected to the rotating rod 9.
[0027] In this embodiment, the L-shaped rod 54 serves to support the mixing tank 55.
[0028] Specifically, a vertical plate 56 is fixedly mounted on the horizontal end of the U-shaped base 4. A second motor 57 is fixedly mounted on the surface of the vertical plate 56. A special-shaped gear 58 is fixedly mounted on the output end of the second motor 57. Only one-third of the teeth on the surface of the special-shaped gear 58 are visible. The inner walls on both sides of the strip frame 53 are provided with tooth-like structures. The special-shaped gear 58 meshes with the tooth-like structures on the inner walls on both sides of the strip frame 53. The second motor 57 drives the special-shaped gear 58 to rotate, and the special-shaped gear 58 drives the strip frame 53 to move.
[0029] In this embodiment, a flipping device 6 is provided on the surface of one of the fixed plates 2. The flipping device 6 includes a third motor 61, which is fixedly installed on the surface of one of the fixed plates 2. The output end of the third motor 61 is fixedly connected to one of the rotating shafts 3. When the mixing is completed and unloading is required, the sliding plate 63 is first slid, causing the sliding plate 63 to move inside the vertical groove 62. The movement of the sliding plate 63 inside the vertical groove 62 will compress the spring 67, causing the spring 67 to be compressed. At the same time, the movement of the sliding plate 63 inside the vertical groove 62 will also drive the insertion rod 64 to move. The movement of the insertion rod 64 will cause it to move out of the insertion hole 65. The separation of the insertion rod 64 and the insertion hole 65 will cause one of the rotating shafts 3 to lose its limit. At this time, the third motor 61 can be turned on. The third motor 61 will start and drive one of the rotating shafts 3 to rotate. The rotation of one of the rotating shafts 3 will drive the U-shaped seat 4 to rotate. The rotation of the U-shaped seat 4 will drive the other rotating shaft 3 to rotate. The U-shaped seat 4 rotates, ultimately driving the mixing tank 55 to rotate. When the mixing tank 55 rotates to the position where the feed hopper 7 faces downwards, the third motor 61 is turned off, and then the sliding plate 63 is released. The spring force of the spring 67 causes the insertion rod 64 to be reinserted into the corresponding insertion hole 65, thereby restricting the rotation of one of the rotating shafts 3. Then, the collecting mechanism is placed below the feed hopper 7, and the hopper cover 8 is opened. At this time, the mortar inside the mixing tank 55 will flow from the feed hopper 7 into the collecting mechanism. Through the cooperation of the above structures, the mixing tank 55 can be flipped, which makes it easier for workers to unload the mortar and further improves the practicality of the device.
[0030] Specifically, a vertical groove 62 is provided on the surface of one of the fixed plates 2, a sliding plate 63 is slidably connected inside the vertical groove 62, a plug rod 64 is fixedly installed on the surface of the sliding plate 63, and a plurality of plug holes 65 are provided on the outer wall surface of one of the rotating shafts 3.
[0031] In this embodiment, the insertion rod 64 and the insertion hole 65 serve to restrict the rotation of the rotating shaft 3.
[0032] Specifically, a rectangular plate 66 is fixedly installed on the surface of one of the fixed plates 2, and a spring 67 is fixedly installed between the rectangular plate 66 and the sliding plate 63.
[0033] In this embodiment, the spring 67 serves to limit the position of the slide plate 63 inside the vertical groove 62.
[0034] Working principle: By setting up the reciprocating device 5, when the device is needed, first raise the base plate 1. After raising, feed the material into the mixing tank 55 from the feed hopper 7, then inject water into the mixing tank 55 from the feed hopper 7, and finally close the hopper cover 8. Then start the first motor 11. The first motor 11 drives the rotating rod 9 to rotate, which in turn drives the stirring rod 10 to rotate. The stirring rod 10 stirs the material and water inside the mixing tank 55. At the same time, during the stirring process, the second motor 57 can be started. The second motor 57 drives the special gear 58 to rotate. When the special gear 58 rotates and meshes with the toothed structure on the inner wall of the upper end of the strip frame 53, the strip frame 53 will move to the left. The leftward movement of the strip frame 53 will cause one of the support rods 52 to move into the sleeve 51, while the other support rod 52 moves out of the sleeve 51. As the internal structure moves outward, the strip frame 53 moves to the left, which in turn moves the L-shaped rod 54 to the left. The L-shaped rod 54 moves to the left, which in turn moves the mixing tank 55 to the left. When the shaped gear 58 rotates and meshes with the tooth-like structure on the lower inner wall of the strip frame 53, the strip frame 53 moves to the right, which in turn moves the mixing tank 55 to the right. As the shaped gear 58 rotates continuously, the mixing tank 55 moves back and forth, which makes the mortar inside the mixing tank 55 more evenly mixed. Through the cooperation of the above structures, when the mixing tank 55 shakes left and right, the liquid inside the mixing tank can repeatedly wash the mixing rod 10 and the rotating rod 9, washing off the unmixed mortar material adhering to the mixing rod 10 and the rotating rod 9, and mixing it with the liquid, which improves the fluidity and water retention of the mortar and saves a lot of mortar material. When mixing is complete and unloading is required, first slide the slide plate 63, causing it to move inside the vertical groove 62. This movement compresses the spring 67. Simultaneously, the movement of the slide plate 63 also moves the insertion rod 64, causing it to move out of the insertion hole 65. This separation of the insertion rod 64 and insertion hole 65 causes one of the rotating shafts 3 to lose its limit position. At this point, the third motor 61 can be activated. The third motor 61 starts, causing one of the rotating shafts 3 to rotate. This rotation of the rotating shaft 3 causes the U-shaped seat 4 to rotate, which in turn causes the other rotating shaft 3 to rotate. The U-shaped seat 4 rotates, ultimately driving the mixing tank 55 to rotate. When the mixing tank 55 rotates to the position where the feed hopper 7 faces downwards, the third motor 61 is turned off, and then the sliding plate 63 is released. The spring force of the spring 67 causes the insertion rod 64 to be reinserted into the corresponding insertion hole 65, thereby restricting the rotation of one of the rotating shafts 3. Then, the collecting mechanism is placed below the feed hopper 7, and the hopper cover 8 is opened. At this time, the mortar inside the mixing tank 55 will flow from the feed hopper 7 into the collecting mechanism. Through the cooperation of the above structures, the mixing tank 55 can be flipped, which makes it easier for workers to unload the mortar and further improves the practicality of the device.
