Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, specifically to a temporary mixer for concrete. Background Technology

[0002] Traditional concrete mixing equipment is mostly large-scale concrete mixers, either truck-mounted or ground-mounted. While these mixers are highly efficient, they are more suitable for large-scale projects. For smaller projects requiring less concrete, typically around 1 cubic meter, these more expensive mixers are not chosen.

[0003] In small-scale projects, concrete mixing is usually done directly on the ground. Cement, sand, and gravel are arranged in a circle, water is poured into the circle, and then the mixture is mixed manually with shovels. While this method saves costs, the concrete is in direct contact with the ground, which can leave marks and affect the overall appearance. In addition, manual mixing is less effective and takes longer, thus reducing overall work efficiency.

[0004] Therefore, a temporary mixer for concrete is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a temporary mixer for concrete to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temporary concrete mixer, including a trolley, a frame on the trolley, fixing devices installed at both ends of the frame, a drive motor installed in the middle of the frame, a connecting cylinder installed on the output shaft of the drive motor, a telescopic rod slidably connected inside the connecting cylinder, and a limit bolt installed between the connecting cylinder and the telescopic rod.

[0007] Connecting seats are installed on the upper outer side of the connecting cylinder and the lower outer side of the telescopic rod. Stirring rods are hinged to the four sides of the two connecting seats, and the opposite ends of the multiple stirring rods are hinged to each other.

[0008] Preferably, the telescopic rod has multiple through holes evenly distributed on its outer side to facilitate the passage of the limiting bolts, and the bottom end of the connecting cylinder has a hole to facilitate the passage of the limiting bolts.

[0009] Preferably, the fixing device includes a movable plate;

[0010] The movable plate is slidably connected to the frame, and the top of the movable plate is equipped with fixing bolts to facilitate fixing the movable plate.

[0011] Preferably, a threaded rod is threadedly connected to the lower part of the movable plate, and a ball head is installed at one end of the threaded rod.

[0012] Preferably, a ball socket is installed on the outer side of the ball head, a plate is installed on one side of the ball socket, and a rubber pad is installed on one side of the plate.

[0013] Preferably, multiple stirring blades are evenly installed on the outer side of the stirring rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this device allows concrete mixing to be carried out directly inside a cart or other container during some small-scale projects, saving the manual mixing process, improving the overall work efficiency, and also preventing concrete from leaving marks on the ground.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a temporary concrete mixer, including a cart 1, a frame 2 on the cart 1, fixing devices 4 installed at both ends of the frame 2, a drive motor 3 installed in the middle of the frame 2, a connecting cylinder 5 installed on the output shaft of the drive motor 3, a telescopic rod 7 slidably connected inside the connecting cylinder 5, and a limit bolt 8 installed between the connecting cylinder 5 and the telescopic rod 7.

[0023] Connecting seats 9 are installed on the upper outer side of the connecting cylinder 5 and the lower outer side of the telescopic rod 7. Stirring rods 6 are hinged to the four sides of the two connecting seats 9, and the opposite ends of the multiple stirring rods 6 are hinged to each other.

[0024] like Figure 2 and Figure 3 As shown: Multiple through holes 10 are evenly provided on the outer side of the telescopic rod 7 to facilitate the passage of the limiting bolt 8, and a hole is provided at the bottom of the connecting cylinder 5 to facilitate the passage of the limiting bolt 8. With the above settings, the limiting bolt 8 can restrict the position between the connecting cylinder 5 and the telescopic rod 7 through the through holes 10 and the hole, thereby adjusting the extension distance of the telescopic rod 7, which facilitates the adjustment of the multiple stirring rods 6 on the outer side.

[0025] like Figure 4 As shown: The fixing device 4 includes a movable plate 41; the movable plate 41 is slidably connected to the frame 2, and a fixing bolt 42 is installed on the top of the movable plate 41 to facilitate fixing the movable plate 41; with the above settings, after the fixing bolt 42 is tightened, the position of the movable plate 41 can be fixed to prevent it from moving at will.

[0026] like Figure 4 As shown: A threaded rod 43 is threadedly connected to the lower part of the movable plate 41. A ball head 44 is installed at one end of the threaded rod 43, and a ball socket 45 is installed on the outer side of the ball head 44. A plate body 46 is installed on one side of the ball socket 45, and a rubber pad is installed on one side of the plate body 46. With the above configuration, the rotation of the threaded rod 43 can move it on the movable plate 41, thereby driving the ball head 44, the ball socket 45 and the plate body 46 to move. The angle of the plate body 46 can be easily adjusted through the ball head 44 and the ball socket 45, thereby more stably restricting the position of the device.

[0027] like Figure 2 and Figure 3 As shown: Multiple mixing blades 61 are evenly installed on the outer side of the mixing rod 6; with the above configuration, the mixing blades 61 can more conveniently and efficiently mix concrete.

[0028] Working principle: First, remove the limiting bolt 8 to allow the telescopic rod 7 to move freely. Then, adjust the position of the telescopic rod 7 according to the size and depth of the trolley 1 so that the multiple stirring rods 6 on the outside can rotate inside the trolley 1 without touching the inner wall of the trolley 1. After the position of the telescopic rod 7 is adjusted, re-fix the limiting bolt 8. Then, the frame 2 is placed on the cart 1, and the movable plates 41 on both sides are adjusted. When the movable plates 41 are in the correct position, they are fixed by the fixing bolts 42. Then, the threaded rod 43 is rotated to move the movable plate 41. The threaded rod 43 drives the plate 46 to contact the outside of the cart 1. The plate 46 can be adjusted more easily by the ball head 44 and the ball socket 45, so that the plate 46 can fit more efficiently against the outer wall of the cart 1, making the fixation more stable. This device can directly mix concrete inside the cart 1 or container. When less concrete is needed, it can avoid starting a large mixing machine. At the same time, when the concrete needs to be stored inside the cart 1 for a long time, it can also be continuously mixed by this device.

[0029] 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.
