Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a mixer used in engineering construction. Background Technology

[0002] With the rapid economic development in recent years, the civil engineering and construction industry has become increasingly popular, and the demand for cement has been increasing. Mixers are widely used in industrial production such as chemical, construction, and environmental protection. A mixer is a type of construction machinery, mainly used for mixing building materials such as concrete, cement, sand, gravel, and various dry mortars. It is a machine with blades rotating in a cylinder or trough to mix various raw materials into a mixture or a mixture of suitable consistency.

[0003] Construction mixers are machines used to thoroughly mix materials required for construction projects, significantly improving construction speed. However, existing construction mixers are inconvenient to move around on construction sites. For example, a construction mixer disclosed in utility model patent application number CN202122067983.9 has a mixer body mounted on a base, with support columns at the four corners of the base. The bottom of the support columns is covered with shock-absorbing pads, and a shock-absorbing mechanism is installed between the base and the mixer body. Moving the mixer requires a dedicated transport vehicle, changing its location and significantly increasing the operating costs of large machinery. Furthermore, concrete residue is easily left inside the mixer body during unloading, necessitating improvements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a mixer for use in engineering construction.

[0005] To solve the above problems, the technical solution of this utility model is as follows: a mixer used in engineering construction, including a U-shaped frame, casters installed at the bottom of the frame, a U-shaped mounting bracket movably provided inside the frame, the mixer being fixedly installed on the mounting bracket, positioning shafts passing through the side walls of the frame being fixedly connected to both sides of the mounting bracket, a worm gear being installed on one of the positioning shafts, a protective shell being fixedly connected to the side of the frame outside the worm gear, a worm being rotatably installed inside the protective shell, and a drive motor for driving the worm to rotate being installed at the bottom of the protective shell.

[0006] Furthermore, a push handle is installed on the side of the frame above the protective shell, and a controller is installed on the side of the protective shell.

[0007] Furthermore, the mixer includes a mixing tank mounted on the top of the mounting frame, a mixing shaft rotatably mounted inside the mixing tank, and multiple mixing blades one and two mounted on the mixing shaft. The mixer also includes a mixing motor mounted at the bottom of the mounting frame, and the output end of the mixing motor is connected to the mixing shaft.

[0008] Furthermore, fixing blocks are fixedly connected to both sides of the mixing tank between the mounting frame, and positioning components are detachably installed on the fixing blocks.

[0009] Furthermore, the positioning component includes a horizontal plate, on one side of which are fixed two positioning rods that penetrate the side wall of the frame. The positioning rods are round rods made of iron. The fixing block has a socket adapted to the positioning rods, and the side wall of the frame has a through hole adapted to the positioning rods. A magnetic block is installed in the socket.

[0010] Furthermore, the frame is symmetrically fixed with retaining rings on both sides outside the positioning shaft.

[0011] The advantages of this utility model compared with the existing technology are as follows: This utility model can move the frame and mixer by means of a push handle and casters, which makes it easy to adjust the position of the mixer; the drive motor drives the positioning shaft and mounting bracket to rotate 160° through the worm and worm wheel, so that the opening of the mixing drum is tilted downward, which makes it easy to discharge the concrete in the mixing drum and effectively avoids concrete residue inside the mixing drum.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown, a mixer used in engineering construction includes a U-shaped frame 1, casters 2 installed at the bottom of the frame 1, a U-shaped mounting frame 3 movably installed inside the frame 1, the mixer being fixedly installed on the mounting frame 3, and a push handle 9 installed on the frame 1.

[0021] The frame 1 and the mixer can be moved by the push handle 9 and the casters 2, which makes it easy to adjust the position of the mixer.

[0022] like Figure 3 and Figure 4 As shown, the mixer includes a mixing tank 11 mounted on the top of the mounting frame 3. A mixing shaft 12 is rotatably mounted inside the mixing tank 11. Multiple mixing blades 13 and 14 are mounted on the mixing shaft 12. The mixer also includes a mixing motor 15 mounted at the bottom of the mounting frame 3. The output end of the mixing motor 15 is connected to the mixing shaft 12.

[0023] The mixing motor 15 drives the mixing blades 13 and 14 to rotate via the mixing shaft 12, which can mix the concrete evenly.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, both sides of the mounting frame 3 are fixedly connected to positioning shafts 4 that pass through the side walls of the frame 1. The outer sides of the frame 1 are symmetrically fixedly connected to fixing rings 20 that are sleeved on the outside of the positioning shafts 4. A worm gear 5 is installed on one of the positioning shafts 4. A protective shell 6 is fixedly connected to the side of the frame 1 outside the worm gear 5. A worm 7 is rotatably installed inside the protective shell 6. A drive motor 8 for driving the worm 7 to rotate is installed at the bottom of the protective shell 6.

[0025] The drive motor 8 drives the worm gear 7 to rotate, and the worm gear 7 drives the positioning shaft 4 and the mounting bracket 3 to rotate through the worm wheel 5, so that the mixer rotates around the positioning shaft 4. This allows the opening of the mixing bucket 11 to be rotated to the lower side. At this time, the angle between the center line of the mixing bucket 11 and the vertical direction is 15-30°, which makes it easier to discharge the mixed concrete.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, fixing blocks 16 are fixedly connected to both sides of the mixing tank 11 between the mounting bracket 3. Positioning components are detachably installed on the fixing blocks 16. The positioning components include a horizontal plate 17. Two positioning rods 18 that penetrate the side wall of the frame 1 are fixedly connected to one side of the horizontal plate 17. The positioning rods 18 are round rods made of iron. The fixing blocks 16 are provided with insertion holes that are compatible with the positioning rods 18. The side wall of the frame 1 is provided with through holes that are compatible with the positioning rods 18. A magnetic block 19 is installed in the insertion hole.

[0027] The installation of the fixing block 16 can improve the stability of the mixing tank 11. During mixing, the positioning rod 18 of the positioning member is inserted into the socket. The attraction between the magnetic block 19 and the positioning rod 18 can prevent the positioning member from falling off. At the same time, the installation of the positioning member can improve the stability of the mounting frame 3 during mixing.

[0028] In practical use, the push handle 9 and casters 2 can be used to move the frame 1 and the mixer, making it easy to adjust the position of the mixer. The mixing motor 15 drives the mixing blades 13 and 14 to rotate through the mixing shaft 12, which can mix the concrete evenly. After removing the positioning piece, the drive motor 8 drives the positioning shaft 4 and the mounting bracket 3 to rotate through the worm gear 7 and worm wheel 5. The mounting bracket 3 drives the mixer to rotate 160°, so that the opening of the mixing drum 11 is tilted downward, which makes it easier to discharge the concrete in the mixing drum 11 and effectively avoids concrete residue inside the mixing drum 11.
