Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically to a low-alkali concrete mixer. Background Technology

[0002] Low-alkali concrete refers to concrete with an alkali content below a certain standard, usually referring to concrete with a sodium ion content of less than 3 kg / m³. Compared with ordinary concrete, low-alkali concrete has stronger durability, resistance to alkali erosion, and resistance to corrosion. It has wide application value in some special construction fields, such as nuclear power plants, chemical plants, bridges, and ports.

[0003] Currently, low-alkali concrete is produced by mixing cement, sand and gravel aggregates, and water in a mixer during construction. Concrete mixers can be divided into vertical and horizontal types. Horizontal concrete mixers mainly consist of a mixing drum, feeding and unloading mechanisms, a water supply system, a prime mover, a transmission mechanism, a frame, and a support device. For example, patent CN211492192U discloses a horizontal concrete mixer that achieves high-efficiency mixing by installing a combined mixer and mixing shaft driven by a motor and reducer inside the mixing drum. This mixer needs to be placed on a hardened, level surface during operation. Uneven ground not only affects the mixer's operation but also causes a large amount of sand and gravel inside the mixer to sink to the lower part, resulting in poor concrete mixing. Furthermore, for small-scale on-site projects, hardening and leveling the ground specifically for the mixer is time-consuming and labor-intensive. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-alkali concrete mixer that can keep the base in a horizontal position at all times. The mixer body can maintain normal operation in a horizontal state, and there will be no unevenness that would cause uneven mixing, thus ensuring the concrete mixing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-alkali concrete mixer, comprising a base and a mixer body, a leveling mechanism, and a strip level mounted on the base, wherein multiple leveling mechanisms and strip levels are provided, and the leveling mechanisms and strip levels are arranged in a one-to-one correspondence; the leveling mechanism includes a support base and a top rod; the support base is located on the lower side of the base and is threadedly connected to the lower end of the top rod; at least part of the upper part of the top rod abuts against the base.

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0021] See Figure 1-3 In one embodiment of this utility model, a low-alkali concrete mixer includes: a mixer body 1, a leveling mechanism 2, a strip level 3, and a base 4. The mixer body 1, the leveling mechanism 2, and the strip level 3 are all mounted on the base 4. There are four leveling mechanisms 2, which are distributed at the four corners of the base 4. Similarly, there are four strip levels 3, which are distributed along the four edges of the base 4. With the cooperation of the leveling mechanism 2 and the strip level 3, the base 4 can always maintain a horizontal posture. The mixer body 1 can maintain normal operation in a horizontal state, and there will be no unevenness that would cause uneven mixing, thus ensuring the concrete mixing effect.

[0022] The mixer body 1 includes components such as a mixing drum 11, a discharge valve 12, a motor 13, a mixing shaft 14, a spiral blade 15, a reducer, a coupling, a bearing seat, and support feet. The mixing drum 11 is fixedly mounted on the base 4 via support feet, and the axis of the mixing drum 11 is parallel to the main end face of the base 4. The mixing shaft 14 is located inside the mixing drum 11 via a bearing seat, and the spiral blade 15 is mounted on the mixing shaft 14. The motor 13 is mounted on the base 4 and located on the right side of the mixing drum 11. One end of the mixing shaft 14 is connected to the output shaft of the motor 13 via a reducer and a coupling. The discharge valve 12 is located at the left end of the mixing drum 11. Compared with the prior art, the discharge port is located at the left end of the mixing drum 11 rather than the bottom, which allows the mixing drum 11 to be closer to the base 4, making the center of gravity of the mixer body 1 lower and achieving better stability.

[0023] The base 4 is a square frame structure, with a corner block 41 at each of its four corners for reinforcing the structure. The corner block 41 has a through hole. The corner block 41 is arranged in a one-to-one correspondence with the leveling mechanism 2.

[0024] In this embodiment, the leveling mechanism 2 mainly includes a support base 21, a top rod 22, and a stop block 27. The support base 21 is a conical cylinder structure and is located on the lower side of the corner block 41. The top rod 22 passes through the through hole and extends into the support base 21. The top rod 22 is threadedly connected to the upper part of the support base 21. The stop block 27 is fixedly sleeved on the top rod 22 and is located between the support base 21 and the corner block 41. The outer diameter of the stop block 27 is larger than the inner diameter of the through hole. By rotating the top rod 22, the top rod 22 can be raised and lowered relative to the support base 21. The stop block 27 pushes the corner block 41 to adjust the vertical height of the corner block 41, thereby realizing the leveling function.

[0025] In one embodiment, a pressure-relieving spring 24 is also provided between the abutment block 27 and the corner block 41. The pressure-relieving spring 24 is sleeved on the top rod 22. The setting of the pressure-relieving spring 24 can change the rigid end between the corner block 41 and the leveling mechanism 2 to soft contact. The pressure-relieving spring 24 can filter the vibration generated by the mixing of the mixer body 1, making the mixer work more stably.

[0026] In one embodiment, the bottom of the support base 21 is provided with an anti-slip groove 211, which further improves the adaptability of the leveling mechanism 2 to different roadbeds.

[0027] In one embodiment, the leveling mechanism 2 further includes a limiting block 26, which is fixedly disposed at the lower end of the top rod 22 to prevent the top rod 22 from slipping off the support seat 21. In practice, the limiting block 26 can be fixed to the lower end of the top rod 22 by screws, and the screws are coaxial with the top rod 22.

[0028] In one embodiment, the leveling mechanism 2 further includes a positioning spring 23 and a top block 25. The top block 25 is fixedly mounted on the top of the top rod 22, and the positioning spring 23 is sleeved on the top rod 22 and compressed between the top block 25 and the corner block 41, so as to prevent the leveling mechanism 2 from becoming loose. Furthermore, the leveling mechanism 2 is also equipped with an adjusting rod 5. The top block 25 has an adjusting hole 251 that matches the adjusting rod 5. When the adjusting rod 5 is used as a tool, it passes through the adjusting hole 251, which allows the top rod 22 to be rotated easily.

[0029] This technical solution involves installing a leveling mechanism and a strip level on the base of the mixer body. With the cooperation of the leveling mechanism and the strip level, the base can always maintain a horizontal posture. The mixer body can maintain normal operation when it is horizontal, and there will be no unevenness that would cause uneven mixing, thus ensuring the concrete mixing effect.

[0030] 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 this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
