Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0050] In this embodiment, as Figure 1 and Figure 2 As shown, a high-efficiency sand mixer includes: a sand mixing tank 1, with a bearing support 11 connected to the outer periphery of the sand mixing tank 1 via a bearing; a water supply pipe 2, positioned on the central axis of the sand mixing tank 1, and rotatably connected to the sand mixing tank 1 via a bearing; a flange 23 is provided at the water inlet end of the water supply pipe 2, and the end of the water supply pipe 2 away from the flange 23 extends into the cavity of the sand mixing tank 1; a nozzle 21 is provided on the portion of the water supply pipe 2 located in the cavity of the sand mixing tank 1, and the nozzles 21 are evenly distributed based on the water supply pipe 2.
[0051] Thus, under the action of an external power source, the sand mixing tank 1 is driven to rotate in the support bracket 11. The material in the sand mixing tank 1 moves to the highest point as the sand mixing tank 1 rotates and falls, so as to mix the material in the sand mixing tank 1. At the same time, the external water source is connected to the flange 23. The water source enters the inner cavity of the water supply pipe 2 and is sprayed onto the material through the nozzle 21. The nozzle 21 makes the water supply to the material more uniform. The water supply pipe 2 extends into the inner cavity of the sand mixing tank 1 to supply water to the material in motion, which facilitates the combination of water source and material.
[0052] Specifically, the inner wall of the sand mixing tank 1 is machined with grooves to drive the material to rotate with the sand mixing tank 1 to the highest point and fall. A strip-shaped discharge port is opened at the top of the sand mixing tank 1. One end of the sand mixing tank 1 is designed to be open. The water supply pipe 2 is used to directly supply water to the inside of the material to facilitate the combination of water source and material. The design of multiple nozzles 21 is to increase the uniformity of water supply (the number of nozzles 21 used is determined according to the usage requirements).
[0053] In some embodiments, such as Figure 2 As shown, the water supply pipe 2 is also equipped with a dispersion cap 22, which is used to buffer the impact of sand and gravel falling from the sand mixing tank 1 on the water supply pipe 2.
[0054] The dispersion cap 22 includes: a support rod 221, which is located at the end of the water supply pipe 2 away from the nozzle 21. A protective plate 222 is fixedly connected to the end of the support rod 221 away from the water supply pipe 2. The protective plate 222 is machined with an arc surface. The protective plate 222 partially wraps around the outer periphery of the water supply pipe 2.
[0055] Specifically, multiple support rods 221 are provided, and the number of support rods 221 used is determined according to the usage requirements. The arc surface design of the guard plate 222 is used to disperse the falling materials. The guard plate 222 partially wraps around the outer periphery of the water supply pipe 2 to prevent the materials from directly impacting the water supply pipe 2, thus protecting the water supply pipe 2.
[0056] It should be noted that the dispersion cap 22 is used to buffer the impact force on the water supply pipe 2 when the material in the mixing tank 1 falls to the highest point. The dispersion cap 22 can be made of elastic materials, such as rubber or silicone. The dispersion cap 22 performs secondary dispersion on the falling material, increasing the mixing efficiency of the material.
[0057] In some embodiments, such as Figure 5 As shown, the feed end of the sand mixing tank 1 is equipped with a feed assembly 3;
[0058] The feeding assembly 3 includes: a sealing shell 31, which is connected to the feeding end of the sand mixing tank 1 via a bearing; a guide bend 32, the vertical pipe of which is fixedly connected to the sealing shell 31, and the inclined pipe of which extends to the space between the water supply pipe 2 and the sand mixing tank 1; and a connecting frame 33, one end of which is fixedly connected to the bearing support 11, and the other end of which is fixedly connected to the sealing shell 31.
[0059] Specifically, the sealing shell 31 seals the open end of the sand mixing tank 1, the guide pipe 32 is used to guide the material into the sand mixing tank 1, and the connecting frame 33 is used to fix the position of the sealing shell 31.
[0060] In some embodiments, such as Figure 6 As shown, a discharge assembly 4 is arranged on the outer periphery of the sand mixing tank 1;
[0061] The unloading assembly 4 includes: a mounting ring 41, which is rotatably connected to the sand mixing tank 1 via a bearing; and a baffle plate 42, which is used to block the discharge port of the sand mixing tank 1. One end of the baffle plate 42 is fixedly connected to the mounting ring 41, and the other end of the baffle plate 42 is equipped with a bolt 421. The baffle plate 42 is connected to the sand mixing tank 1 via the bolt 421.
[0062] The mounting ring 41 drives the baffle plate 42 to rotate around the outer periphery of the sand mixing tank 1 via the bearing. The baffle plate 42 has a baffle length that matches the discharge port of the sand mixing tank 1. Threaded holes corresponding to bolts 421 are machined on the outer periphery of the sand mixing tank 1.
[0063] The baffle plate 42 is designed to be separable from the discharge port of the sand mixing tank 1 to facilitate discharge.
[0064] In some embodiments, such as Figure 6 As shown, the support bracket 11 is equipped with a driving component 5, which is used to drive the sand mixing tank 1 to rotate.
[0065] The driving component 5 includes: a drive shaft 51, which is rotatably connected to the support bracket 11, and a first motor 511 is configured at the input end of the drive shaft 51; a first gear 52, whose center hole is fixedly connected to the drive shaft 51; and a second gear 53, whose center hole is fixedly connected to the sand mixing tank 1, and which meshes with the first gear 52.
[0066] Specifically, the first motor 511 provides power for the rotation of the transmission shaft 51, and the second gear 53 meshes with the first gear 52 for transmission. Under the action of the meshing of the second gear 53 and the first gear 52, the sand mixing tank 1 is driven to rotate in the support bracket 11.
[0067] Furthermore, provided that the mixing tank 1 can rotate, the drive component 5 can be replaced with other drive structures.
[0068] In some embodiments, such as Figure 1 As shown, a base 6 is fixedly connected to the bottom of the support bracket 11. The base 6 is equipped with a traction rod 61. One end of the traction rod 61 is fixedly connected to the base 6, and the other end of the traction rod 61 is fixedly connected to the support bracket 11.
[0069] Specifically, the base 6 is used to support the overall mechanism, and the traction rod 61 is provided with two rods symmetrically distributed based on the bearing bracket 11.
[0070] In some embodiments, such as Figure 1 As shown, the traction rod 61, the base 6, and the support bracket 11 form a triangular structure to enhance the stability of the support bracket 11.
[0071] The traction rod 61, the base 6, and the support bracket 11 form a triangular structure, which makes the support bracket 11 more stable during use.
[0072] In some embodiments, such as Figure 4 and Figure 5 As shown, the inner cavity of the sand mixing tank 1 is equipped with an auxiliary discharge assembly 7;
[0073] The auxiliary discharge assembly 7 includes: a double-ended threaded rod 71, which is located in the inner cavity of the sand mixing tank 1 and is connected to the sand mixing tank 1 through a bearing. A second motor 711 is installed at the input end of the double-ended threaded rod 71; a scraper annular plate 72, the outer periphery of which abuts against the inner wall of the sand mixing tank 1, and a guide rod 721 is slidably connected in the limiting hole of the scraper annular plate 72. The guide rod 721 is fixedly connected to the sand mixing tank 1.
[0074] Specifically, the second motor 711 provides power for the rotation of the double-ended threaded rod 71 in the sand mixing tank 1. The double-ended threaded rod 71 is used to drive the scraping annular plate 72 to move towards each other along the inner wall of the sand mixing tank 1. The guide rod 721 assists the scraping annular plate 72 to move laterally, and scrapes off the material attached to the inner wall of the sand mixing tank 1 through the scraping annular plate 72.
[0075] The scraper ring plate 72 has a through groove in the middle. The diameter of the through groove is larger than the outer diameter of the water supply pipe 2, the nozzle 21 and the dispersion cap 22. The design of the through groove allows the scraper ring plate 72 to move laterally on the outer wall of the water supply pipe 2.
[0076] In some embodiments, such as Figure 5 As shown, the double-threaded rod 71 is arranged in parallel with the guide rod 721.
[0077] The design of the double-threaded rod 71 and the guide rod 721 is such that the guide rod 721 is used to assist the scraper ring plate 72 in moving laterally along the outer wall of the double-threaded rod 71.
[0078] In some embodiments, such as Figure 3 As shown, the two scraper ring plates 72 are symmetrically distributed based on the sand mixing tank 1.
[0079] The design of the two scraper ring plates 72 allows them to move simultaneously toward the discharge port of the sand mixing tank 1 during the discharge process, thereby pushing the material out.
[0080] The working principle of this application is illustrated below with a preferred embodiment:
[0081] The material enters the mixing tank 1 through the guide bend 32. Then, the first motor 511 is started. The output end of the first motor 511 drives the transmission shaft 51 to rotate in the bearing support 11 through the coupling. At the same time, the first gear 52 drives the second gear 53 outside the mixing tank 1 to rotate. The mixing tank 1 rotates in the bearing support 11 and the sealing shell 31. The material in the mixing tank 1 moves to the highest point as the mixing tank 1 rotates and falls. The falling material lands on the top of the guard plate 222. The guard plate 222 changes the falling trajectory of the material to mix the material in the mixing tank 1. At the same time, the external water source is connected to the flange 23. The water source enters the inner cavity of the water supply pipe 2 and is sprayed onto the material through the nozzle 21. The nozzle 21 makes the water supply to the material more uniform.
[0082] During material discharge, the discharge port of the sand mixing tank 1 is adjusted to face the ground by the first motor 511. Then, the bolt 421 is rotated to separate from the sand mixing tank 1. The baffle plate 42 is driven to separate from the discharge port of the sand mixing tank 1 by rotating the mounting ring 41, so as to discharge the material. At the same time, the second motor 711 is started. The second motor 711 drives the double-headed threaded rod 71 to rotate. Under the action of the double-headed threaded rod 71, the two scraping annular plates 72 move along the outer wall of the guide rod 721. The two scraping annular plates 72 move towards the discharge port of the sand mixing tank 1 to accelerate the discharge speed of the material.
[0083] 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.
