Description

Technical Field

[0001] This utility model relates to the field of concrete admixture processing technology, specifically a grinding equipment for processing concrete admixtures. Background Technology

[0002] With the continuous advancement of global infrastructure construction, such as the large-scale development of highways, bridges, and high-rise buildings, the usage of concrete, an indispensable material in construction, continues to rise. Concrete admixtures, as key materials that can significantly improve concrete performance (such as strength, durability, and workability), are also experiencing rapid market demand growth. In the processing of concrete admixtures, grinding of some raw materials is often required. While existing grinding equipment for concrete admixture processing can generally meet daily needs, some shortcomings still require improvement.

[0003] Most commercially available grinding equipment for concrete admixtures consists of a hopper and a grinding disc. During grinding, the additive raw materials are fed into the hopper and then ground by the grinding disc. However, in actual use, the additive raw materials tend to produce powder that is scattered outwards during the grinding process, and this powder is difficult to collect and clean up afterward. Therefore, we propose a grinding equipment for concrete admixtures to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding equipment for processing concrete admixtures, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding equipment for processing concrete admixtures, comprising a grinding equipment, a grinding motor disposed outside the grinding equipment, and a dispensing chamber disposed at the upper end of the grinding equipment. The dispensing chamber has a dispensing port on its front top, and a sealing cover is slidably connected to the dispensing port. A sleeve is fixed to the rear top of the dispensing chamber, and a movable plate is disposed inside the sleeve. The outer wall of the front end of the movable plate is connected to the outer wall of the sealing cover via two sets of connecting rods. The outer wall of the rear end of the movable plate is connected to a side plate via two sets of connecting rods. A pull handle is installed at the top of the side plate. Return springs are wound around the outside of both sets of connecting rods. An auxiliary positioning component is disposed at the top of the sleeve.

[0006] As a further preferred embodiment of this technical solution, the auxiliary positioning component includes a flap rotatably connected to the middle of the top of the side plate, a fixed plate fixed to the top of the sleeve, and multiple sets of positioning grooves equally spaced on the fixed plate. The front end of the flap can enter the positioning groove on the fixed plate.

[0007] As a further preferred embodiment of this technical solution, the outer wall of the movable plate is fully fitted with the inner wall of the sleeve, and the movable plate and the sleeve are slidably connected.

[0008] As a further preferred embodiment of this technical solution, a sealing ring is adhesively bonded to the outer wall of the sealing cover.

[0009] As a further preferred embodiment of this technical solution, the two ends of the return spring on the outside of the second connecting rod are respectively connected to the outer wall of the rear end of the movable plate and the inner wall of the sleeve, and the movable plate is elastically connected to the inner wall of the sleeve through two sets of return springs.

[0010] As a further preferred embodiment of this technical solution, the outer surface of the handle is provided with anti-slip texture.

[0011] This utility model provides a grinding equipment for processing concrete admixtures, which has the following beneficial effects:

[0012] 1. This utility model has a horizontally movable sealing cover installed outside the inlet. The return springs on the two sets of connecting rods can release their elasticity, allowing the movable plate to move the sealing cover quickly to the front end under the elasticity of the two sets of return springs. This allows the sealing cover to quickly form a seal at the inlet, effectively preventing the raw material powder from escaping from the inlet and improving the convenience of using the device.

[0013] 2. This utility model has a rotatable flap installed on the side plate, which works in conjunction with a fixed plate at the top of the sleeve. When the handle is pulled, the movable plate moves the sealing cover to the rear end, allowing the flap to rotate into the positioning groove at the corresponding position on the fixed plate. This allows the flap to limit the side plate to the front end, requiring the user to continuously pull the handle when feeding material into the feeding port, thus improving the convenience of using the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0022] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0023] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0024] This utility model provides a technical solution: such as Figures 1 to 5As shown in this embodiment, a grinding equipment for processing concrete admixtures includes a grinding equipment 1, a grinding motor 2 disposed outside the grinding equipment 1, and a feeding chamber 3 disposed at the upper end of the grinding equipment 1. A feeding port 4 is opened on the front side of the top of the feeding chamber 3, and a sealing cover plate 5 is slidably connected to the feeding port 4. A sleeve 6 is fixed on the rear side of the top of the feeding chamber 3. A movable plate 7 is disposed inside the sleeve 6. The outer wall of the front end of the movable plate 7 is connected to the outer wall of the sealing cover plate 5 by two sets of connecting rods 1 8. The outer wall of the rear end of the movable plate 7 is connected to a side plate 10 by two sets of connecting rods 2 9. A pull handle 11 is installed on the top of the side plate 10. A return spring 12 is wound around the outside of both sets of connecting rods 2 9. An auxiliary positioning component is disposed on the top of the sleeve 6.

[0025] By installing a laterally movable sealing cover 5 outside the inlet 4, the pull handle 11 can be pulled to move the movable plate 7 inside the sleeve 6 laterally. The movable plate 7 then moves the sealing cover 5 quickly to the rear end, releasing the seal on the inlet 4. Material can then be fed into the inlet 4. When it is necessary to grind the additive raw materials, the pull force on the pull handle 11 can be released, allowing the return springs 12 outside the two sets of connecting rods 9 to release their elasticity. Under the elasticity of the two sets of return springs 12, the movable plate 7 can move the sealing cover 5 quickly to the front end, forming a seal on the inlet 4. This effectively prevents the raw material powder from escaping from the inlet 4, improving the convenience of using the device.

[0026] In other embodiments, the auxiliary positioning component includes a flap 13 rotatably connected to the middle of the top of the side plate 10, a fixing plate 14 fixed to the top of the sleeve 6, and multiple sets of positioning grooves 15 equally spaced on the fixing plate 14. The front end of the flap 13 can enter the positioning groove 15 on the fixing plate 14.

[0027] By installing a rotatable flap 13 on the side plate 10, and cooperating with the fixed plate 14 at the top of the sleeve 6, when the handle 11 is pulled, the movable plate 7 moves the sealing cover 5 to the rear end, allowing the flap 13 to rotate into the positioning groove 15 at the corresponding position on the fixed plate 14. This allows the flap 13 to limit the side plate 10 to the front end, requiring the user to continuously pull the handle 11 when feeding material into the feeding port 4, thus improving the convenience of using the device.

[0028] In other embodiments, the outer wall of the movable plate 7 is fully fitted with the inner wall of the sleeve 6, and the movable plate 7 and the sleeve 6 are slidably connected.

[0029] With this design, when the movable plate 7 moves laterally along the inside of the sleeve 6, it can effectively prevent the movable plate 7 from shaking significantly during the movement, thereby effectively improving the stability of the movable plate 7 during movement.

[0030] In other embodiments, a sealing ring is adhesively bonded to the outer wall of the sealing cover 5;

[0031] This design effectively reduces the gap between the sealing cover 5 and the inner wall of the inlet 4 on the inlet chamber 3, thereby improving the sealing effect of the sealing cover 5 on the inlet 4.

[0032] In other embodiments, the two ends of the return spring 12 outside the connecting rod 2 9 are respectively connected to the outer wall of the rear end of the movable plate 7 and the inner wall of the sleeve 6, and the movable plate 7 is elastically connected to the inner wall of the sleeve 6 through two sets of return springs 12.

[0033] This design allows the return springs 12 outside the two sets of connecting rods 9 to continuously apply a spring force towards the front end to the movable plate 7, enabling the movable plate 7 to drive the sealing cover 5 to move forward quickly, so that the sealing cover 5 can quickly seal the injection port 4.

[0034] In other embodiments, the outer surface of the handle 11 is provided with anti-slip texture;

[0035] This design effectively increases the friction between the user's hand and the surface of the handle 11 when the user pulls the handle 11, making it easier to pull the handle 11 with less effort.

[0036] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
