Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a premixing device that facilitates the removal of the hopper. Background Technology

[0002] Concrete production refers to the process of mixing and processing raw materials such as cement, sand, gravel, and mineral admixtures into concrete. Concrete is a widely used basic material in construction engineering, possessing advantages such as high strength, good durability, and relatively low cost.

[0003] Premixing equipment is required during concrete production to mix various raw materials (such as sand, stone, cement, etc.) in a certain proportion and formula to ensure the quality and uniformity of concrete. The mixing equipment is usually equipped with hoppers to store different types of raw materials. During mixing, the raw materials in the hoppers are discharged into the mixing structure for mixing.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. The hopper of some existing ordinary premixing equipment is usually installed with the equipment by screws. When it is necessary to clean or maintain the hopper, multiple screws need to be removed, which is time-consuming and laborious, affecting the efficiency of cleaning and maintaining the hopper; 2. When using some existing ordinary premixing equipment, the operation method is relatively rough. After the operator opens the hopper valve, the raw materials are directly discharged into the mixing structure below, resulting in large fluctuations in the weight of the raw materials discharged each time. It is difficult to ensure the accuracy of the proportion of premixed raw materials in each batch, which ultimately affects the quality stability of the mixed product. Utility Model Content

[0031] In this embodiment, as Figure 2 As shown, the stirring blades 108 form a rotating mechanism with the first reduction motor 106 via the rotating rod 107; when the first reduction motor 106 is started, the rotating rod 107 can drive several stirring blades 108 to rotate, which can stir and mix the raw materials in the mixing tank 101.

[0032] In this embodiment, as Figure 2 As shown, the fixing block 102 and the support rod 103 are set as a group, and there are three groups in total. The three groups of fixing blocks 102 and support rods 103 are arranged in a ring with the vertical center line of the mixing tank 101 as the origin. The mixing tank 101 can be supported by the three groups of fixing blocks 102 and support rods 103. The support plate 201 can be supported by the three support rods 103. The bottom of the mixing tank 101 is shaped like a bucket. When the first electric valve 104 is opened, the raw materials in the mixing tank 101 can be discharged.

[0033] In this embodiment, as Figure 3 and Figure 5As shown, the weight sensor 202 and the support ring 203 are set as a group, and there are three groups in total.

When the first fixing ring 209 is in contact with the third fixing ring 303, the third fixing ring 303 can support the first fixing ring 209. When the first fixing ring 209 moves, it slides in the ring frame composed of the four arc-shaped plates 302, which can improve the stability of the first fixing ring 209 when it moves up and down, so that the support bucket 2010 can stably push the hopper assembly 4 upward.

[0036] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the fourth fixing ring 402 is attached to the top of the support ring 203, and there are three hopper assemblies 4 in total. The three hopper assemblies 4 are arranged in a ring with the vertical center line of the support plate 201 as the origin. At the same time, there are four handles arranged in a ring on the top of the hopper body 401. Opening the second electric valve 403 can discharge the raw material in the hopper body 401. The handles on the hopper body 401 make it easy to lift or manually move and remove the hopper assembly 4.

[0037] The usage and advantages of this utility model: This premixing device, which facilitates hopper removal, operates as follows:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, different raw materials are first added to the three hopper components 4. According to the requirements, the corresponding second electric valve 403 is opened, and the raw materials are discharged from the hopper body 401. The weight sensor 202 senses the weight change of the corresponding hopper component 4. When the weight of the hopper component 4 decreases by the corresponding weight, the corresponding second electric valve 403 is closed. At the same time, the first reduction motor 106 is started, which drives several stirring blades 108 to rotate through the rotating rod 107 to stir and mix the raw materials in the mixing tank 101. When the stirring is finished, the first electric valve 104 is started to discharge the mixed raw materials in the mixing tank 101. When the equipment is finished and the hopper needs to be cleaned or maintained, the second reduction motor 206 is started, which drives the three sets of first fixing rings 209 and support buckets 2010 to move upward through the threaded rod 207 and Y-shaped slider 208. When the support buckets 2010 move upward, they push the corresponding hopper components 4 to move upward. Then, the hopper components 4 are lifted or manually moved out through the handle on the hopper body 401.
