Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of stirring devices, and specifically relates to a vertical stirring device. Background Technology
[0002] Mortar is typically composed of cement, fine aggregates (such as sand), and water. Sometimes chemical additives are also added to improve its performance. By mixing, it is ensured that these components are evenly distributed throughout the mortar, avoiding excessive or insufficient cement, sand, or water in local areas. Therefore, a mixing device is needed to mix the mortar raw materials.
[0003] In existing mixing devices, a rotating column drives the mixing column to rotate, which mixes the mortar. During the mixing process, material adheres to the side wall of the mixing drum, requiring a scraper to scrape it. In existing scraping mechanisms, the scraper is usually fixed at the top of the mixing column. Although this meets the requirement of scraping the side wall of the mixing drum, the scraper is fixed on the rotating column. After long-term use, the scraper is prone to wear. The wear cannot be compensated by moving and adjusting the scraper, and the entire scraper needs to be replaced, resulting in unnecessary waste and increased material costs. Utility Model Content
[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a vertical stirring device. By setting a fixed groove and a fixed block, the fixed block can be moved to move the scraper, thereby compensating for the wear of the scraper. This eliminates the need for workers to frequently replace the scraper, saving production costs.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a vertical stirring device, including a stirring drum, a top plate detachably provided on the top of the stirring drum, a rotating column rotatably provided in the middle of the top plate, a fixing groove symmetrically provided at one end of the rotating column located inside the upper side of the stirring drum, a fixing plate slidably provided inside the fixing groove, a scraper provided at one end of the fixing plate located outside the fixing groove, a plurality of fixing holes evenly opened on the fixing plate, the fixing holes opened on two fixing plates being staggered, and a fixing member for fixing the fixing plate being provided on the outside of the fixing groove.
[0006] As a further improvement of this utility model, the fixing component includes a mounting bracket disposed on the front side of the middle of the fixing groove. The mounting bracket has a sliding groove inside, and a sliding plate is slidably disposed inside the sliding groove. A plug rod adapted to the fixing hole is disposed on one side of the sliding plate located in the fixing groove. A pull rod that is slidably connected to the mounting bracket is disposed at the end of the sliding plate away from the plug rod. Each pull rod is provided with a pull ring. A spring is sleeved on the outer arc surface of the end of the pull rod located inside the mounting bracket. One end of the spring is connected to the inner side wall of the mounting bracket, and the other end is connected to the sliding plate.
[0007] As a further improvement of this utility model, both the fixing groove and the mounting bracket are provided with through holes that are compatible with the insertion rod.
[0008] As a further improvement of this utility model, several stirring rods are evenly arranged on the outer arc surface of the lower end of the rotating column.
[0009] As a further improvement of this utility model, a mounting box is fixedly provided at the upper end of the top plate, a motor is provided at the front end of the mounting box, a worm gear connected to the output end of the motor is rotatably provided at the rear end, and a worm wheel that meshes with the worm gear is provided at the upper end of the rotating column.
[0010] As a further improvement of this utility model, the upper end of the mixing drum is provided with a feed inlet, the lower end of the mixing drum is provided with a discharge outlet, and a discharge valve is provided at the discharge outlet.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] Firstly, by setting a fixed groove and a fixed plate, the fixed plate can slide along the fixed groove to move its position. The fixed plate drives the scraper to move, so that when the scraper is worn, it can be moved to compensate for the wear, eliminating the need for workers to replace the scraper and saving production costs.
[0013] Secondly, by setting up a stirring rod, rotating the rotating column drives the stirring rod to rotate. The rotation of the stirring rod can stir the material inside the mixing drum. The shearing force generated by the stirring rod during rotation helps to break up agglomerates in the material, promotes full contact and reaction between fine particles, and improves the uniformity of mixing.
[0014] Third, by setting up a discharge valve, operators can precisely control the outflow rate and total amount of material as needed, which is crucial for ensuring accurate mixing ratios.
[0015] Fourth, by setting up scrapers, the rotating column drives the fixed groove to rotate, and the fixed groove drives the scrapers to rotate, which can scrape the material on the side wall of the mixing drum, preventing the material from adhering to the inner wall of the mixing drum for a long time, reducing damage to the inner wall caused by corrosion or wear, and extending the service life of the mixing drum.

Detailed Implementation
[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0023] like Figure 1 , 2 As shown in Figure 3, a vertical stirring device includes a stirring drum 101. A top plate 102 is detachably provided on the top of the stirring drum 101. A rotating column 103 is rotatably provided in the middle of the top plate 102. A fixing groove 107 is symmetrically provided at one end of the rotating column 103 located inside the upper side of the stirring drum 101. A fixing plate 104 is slidably provided inside the fixing groove 107. A scraper 105 is provided at one end of the fixing plate 104 located outside the fixing groove 107. A plurality of fixing holes 106 are evenly opened on the fixing plate 104. The fixing holes 106 opened on two fixing plates 104 are staggered. A fixing member for fixing the fixing plate 104 is provided on the outside of the fixing groove 107.
[0024] like Figure 2 , 3As shown in Figure 4, the fixing component includes a mounting bracket 201 located at the front side of the middle of the fixing groove 107. The mounting bracket 201 has a sliding groove inside, and a sliding plate 202 is slidably disposed inside the groove. A plug rod 203, adapted to the fixing hole 106, is located on one side of the sliding plate 202 in the fixing groove 107. A pull rod 204, slidably connected to the mounting bracket 201, is located at the end of the sliding plate 202 away from the plug rod 203. Each pull rod 204 has a pull ring. A spring 205 is sleeved on the outer arc surface of one end of the pull rod 204 inside the mounting bracket 201. One end of the spring 205 is connected to the inner wall of the mounting bracket 201, and the other end is connected to the sliding plate 202. Both the fixing groove 107 and the mounting bracket 201 have through holes adapted to the plug rod 203. When it is necessary to adjust the scraper 10... 5. When moving, pull the lever 204 outward from the fixing groove 107 at one end. The lever 204 drives the slide plate 202 to move its compression spring 205 outward from the mounting bracket 201. As the slide plate 202 moves, it drives the insertion rod 203 to move, thereby disengaging it from the fixing hole 106 on the fixing plate 104. Then, move the fixing plate 104 outward from the fixing groove 107 by a suitable distance, release the lever 204, and let the slide plate 202 move towards the end closer to the fixing plate 104 under the action of the spring 205. This allows the slide plate 202 to drive the insertion rod 203 to insert into the fixing hole 106 on the fixing plate 104, thereby re-fixing the fixing plate 104 and the scraper 105. This eliminates the need for workers to replace the scraper 105, saving production costs and improving equipment efficiency.
[0025] like Figure 2 As shown, several stirring rods 301 are evenly arranged at the lower end of the rotating column 103. The rotation of the stirring rods 301 can ensure that the materials are fully mixed in the mixing drum 101, so that the various components are more evenly distributed and the quality of the final product is improved.
[0026] like Figure 4 As shown, a mounting box 302 is fixedly installed at the upper end of the top plate 102. A motor 303 is installed at the front end of the mounting box 302, and a worm gear 304 connected to the output end of the motor 303 is rotatably installed at the rear end. A worm wheel 305 that meshes with the worm gear 304 is installed at the upper end of the rotating column 103.
[0027] like Figure 1 As shown, the upper end of the mixing drum 101 is provided with a feed inlet 306, and the lower end of the mixing drum 101 is provided with a discharge outlet 307.
[0028] In use, the motor 303 is started, which drives the worm gear 304 to rotate the worm wheel 305. The worm wheel 305 drives the rotating column 103 to rotate, which in turn drives the stirring rod 301 to rotate, thereby stirring the material inside the mixing drum 101. During the stirring process, the material tends to adhere to the side wall of the mixing drum 101. As the rotating column 103 rotates, it can drive the scraper 105 to rotate through the fixing groove 107, thereby allowing the scraper 105 to scrape the side wall of the mixing drum 101. The scraper 105 can continuously scrape the side wall of the mixing drum 101 during rotation, preventing the material from accumulating on the side wall or forming hard lumps, and keeping the inside of the mixing drum 101 clean.
[0029] After a period of use, the scraper 105 will wear out. At this time, pull the lever 204 outward from the fixing groove 107 at one end. The lever 204 drives the slide plate 202 to move its compressed spring 205 outward from the mounting bracket 201. As the slide plate 202 moves, it drives the insertion rod 203 to move, thereby disengaging it from the fixing hole 106 on the fixing plate 104. Then, move the fixing plate 104 outward from the fixing groove 107 by a suitable distance, release the lever 204, and let the slide plate 202 move towards the end closer to the fixing plate 104 under the action of the spring 205. This allows the slide plate 202 to drive the insertion rod 203 to insert into the fixing hole 106 on the fixing plate 104, thereby re-fixing the fixing plate 104 and the scraper 105. This eliminates the need for workers to replace the scraper 105, saving production costs and improving equipment efficiency.
[0030] According to another embodiment of the present invention, such as Figure 1 As shown, a discharge valve 308 is provided at the discharge port 307. The discharge valve 308 allows the operator to precisely control the outflow rate and total amount of material as needed, which is crucial for ensuring the accuracy of the mixture ratio.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
