[0002] A concrete mixer is a machine that mixes cement, sand and gravel aggregates and water to make concrete mixture. It is mainly composed of a mixing drum, a feeding and unloading mechanism, a water supply system, a prime mover, a transmission mechanism, a frame and a supporting device. According to the working nature, it can be divided into intermittent type and continuous type; according to the mixing principle, it can be divided into self-falling type and forced type; according to the installation method, it can be divided into fixed type and mobile type; according to the discharging method, it can be divided into tilting type and non-tilting type; according to the mixing drum structure, it can be divided into pear type, drum type, double cone type, disc vertical shaft type and round groove horizontal shaft type.

The utility model relates to the technical field of concrete production; the horizontal concrete mixer, by removing the fixing seat bolts and nuts on the mounting ring, the electric slider drives the support seat and the support frame, the circular block, the mounting ring and the sealing ring to separate from the mixer body, the support frame drives the L-shaped frame to move, the L-shaped frame drives the U-shaped slider to slide on the mounting frame, and the circular block drives the mixing assembly to separate from the inside of the mixer body, so that the mixer body and the mixing assembly are separated, and when the staff is cleaning, there will be fewer dead corners for cleaning inside, and the mixer body and the mixing assembly can be thoroughly cleaned, and the cleaning effect is better.

However, after reaching the designated position, the mixer needs to be limited and fixed with external objects to avoid movement during the mixing process. It cannot effectively meet people's use needs. For this reason, the present application provides a concrete mixer. Utility Model Content

[0005] The purpose of the present application is to provide a concrete mixer to solve the problem that a mixer with movable wheels needs to be limited and fixed with external objects after reaching a specified position, which cannot effectively meet people's usage needs.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application is provided with an adjustment component, which drives the bidirectional threaded rod to rotate by starting motor 2, so that the two hinged rods rotate and gradually become vertical, thereby pushing the bottom of the anti-skid plate to fit the ground.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a concrete mixer.

[0034] Reference Figure 1A concrete mixer comprises a frame 1, a plurality of supporting legs 2 are symmetrically fixedly connected to the bottom of the frame 1, a plurality of supporting legs 2 are rotatably connected to the bottom of each supporting leg 2, a supporting plate 1 4 is symmetrically fixedly connected to the top of the frame 1, a supporting plate 2 5 is symmetrically fixedly connected to the top of the frame 1, a rotating rod 6 is rotatably connected to the corresponding surface of the supporting plate 1 4 and the supporting plate 2 5, a gear 7 is fixedly connected to the rotating rod 6, a guide wheel 8 is fixedly connected to the rotating rod 6, a mixing tank 10 is arranged on the frame 1, and an adjusting component 13 is installed in the frame 1 A control box 14 is installed on the top of the frame 1, and a buffer plate 15 is slidably arranged inside the control box 14. A controller body 16 is installed on the top of the buffer plate 15, and a vibration reduction assembly 17 is installed on the bottom of the buffer plate 15. A motor 9 is fixedly connected to one side of the support plate 4, and the output end of the motor 9 is fixedly connected to one end of the rotating rod 6. A gear ring 11 is fixedly connected to the stirring tank 10, and the gear 7 is meshed with the gear ring 11. A limiting groove 12 is provided on the stirring tank 10, and the guide wheel 8 is slidably connected inside the limiting groove 12.

[0035] When in use, first push the device to the specified position through the moving wheel 3, and then start the adjustment component 13. The mixer can be limited and stabilized without the help of external objects to prevent the mixer from vibrating during the mixing process, causing the mixer to move and affect the mixing. After the position of the mixer is fixed, the motor 9 can be started to drive the rotating rod 6 to rotate. When the rotating rod 6 rotates, it will drive the gear 7 to rotate. Because the gear 7 is meshing with the gear ring 11, the mixing tank 10 will gradually rotate with the rotation of the gear 7. Through the cooperation of the guide wheel 8 and the limiting groove 12, the mixing process is made more stable, so that the concrete inside can be evenly mixed. At the same time, during the mixing process, the mixer will vibrate. At this time, the vibration of the controller body 16 can be effectively reduced by the vibration reduction component 17, which effectively avoids the damage of the internal parts of the controller body 16 due to long-term vibration, greatly improving the service life of the controller body 16 and the mixer.

[0036] Reference Figure 1 and Figure 2 The adjustment component 13 includes a bidirectional threaded rod 131 rotatably connected to one side of the inside of the frame 1, a motor 2 132 is fixedly connected to one side of the frame 1, an output end of the motor 2 132 is fixedly connected to one end of the bidirectional threaded rod 131, two threaded sleeves 133 are symmetrically threadedly connected to the bidirectional threaded rod 131, and the bottom of the two threaded sleeves 133 are hinged with a hinged rod 134, and the end of the hinged rod 134 away from the threaded sleeve 133 is hinged with a base 135, an adjustment plate 136 is fixedly connected to the bottom of the base 135, and an anti-skid plate 137 is fixedly connected to the bottom of the adjustment plate 136.

[0037] When in use, first start the motor 2 132 to drive the two-way threaded rod 131 to rotate. When the two-way threaded rod 131 rotates, the two threaded sleeves 133 will gradually approach each other on the two-way threaded rod 131. When the two threaded sleeves 133 gradually approach each other, the two hinged rods 134 will be driven to rotate and gradually become vertical, thereby pushing the bottom adjustment plate 136 and the anti-skid plate 137 to gradually approach the ground. When the bottom of the anti-skid plate 137 is in contact with the ground, the rotation of the two-way threaded rod 131 is stopped. Through the cooperation of the adjustment plate 136 and the anti-skid plate 137, the position of the mixer can be limited and stabilized without the help of external force, which facilitates the overall movement and fixation of the mixer and greatly improves the practicability of the mixer.

[0038] Reference Figure 1 , Figure 3 and Figure 4 The vibration reduction assembly 17 includes a fixed block 171 symmetrically fixedly connected to the bottom surface of the control box 14, one end of the fixed block 171 is hinged with a connecting rod 172, the bottom of the buffer plate 15 is symmetrically fixedly connected with a fixed block 173, one end of the fixed block 173 is hinged with a connecting rod 174, the end of the connecting rod 172 away from the fixed block 171 is hinged with a sliding block 175, the end of the connecting rod 174 away from the fixed block 173 is hinged to one end of the sliding block 175, the end of the sliding block 175 away from the hinge port is slidably connected with a shell 176, a cavity is provided inside the shell 176, a spring 177 is fixedly connected inside the shell 176, both ends of the spring 177 are fixedly connected to one end of the sliding block 175, and a damper 18 is symmetrically fixedly connected inside the control box 14, and the top of the damper 18 is fixedly connected to the bottom of the buffer plate 15.

[0039] During use, when the mixer is mixing the internal concrete, the mixer will vibrate. At this time, after the controller body 16 is vibrated, it will squeeze the two fixed blocks 173 to move closer to the fixed block 171, so that the connecting rod 174 and the connecting rod 172 will rotate. Through the rotation of the connecting rod 174 and the connecting rod 172, the two sliding blocks 175 will be pushed to gradually approach and squeeze the spring 177 in the internal cavity of the shell 176. Through the contraction of the spring 177 and the buffering of the damper 18, the vibration of the controller body 16 is greatly reduced, and the internal parts of the controller body 16 are prevented from loosening and being damaged due to long-term vibration. The service life of the controller body 16 and the mixer is effectively improved.

[0040] Reference Figure 1 and Figure 3 Heat dissipation holes 19 are provided on both sides of the control box 14 .

[0041] When in use, the heat dissipation holes 19 on both sides can effectively ventilate and dissipate heat inside the control box 14 , thereby preventing the internal temperature of the control box 14 from being too high and affecting the operation and service life of the controller body 16 .

[0042] The implementation principle of a concrete mixer in this embodiment is as follows: when in use, first, the device is pushed to a specified position by the moving wheel 3, and then the motor 2 132 is started to drive the bidirectional threaded rod 131 to rotate. When the bidirectional threaded rod 131 rotates, the two threaded sleeves 133 gradually approach each other on the bidirectional threaded rod 131. When the two threaded sleeves 133 gradually approach each other, the two hinged rods 134 are driven to rotate and gradually become vertical, thereby pushing the bottom adjustment plate 136 and the anti-skid plate 137 gradually approach the ground. When the bottom of the anti-skid plate 137 is in contact with the ground, the bidirectional threaded rod 131 stops moving. Rotation, through the cooperation of the adjustment plate 136 and the anti-skid plate 137, the position of the mixer can be limited and stabilized without the help of external force, which facilitates the movement and fixation of the mixer as a whole and greatly improves the practicality of the mixer. After the position of the mixer is fixed, the motor 9 can be started to drive the rotating rod 6 to rotate. When the rotating rod 6 rotates, it will drive the gear 7 to rotate. Because the gear 7 is meshed with the gear ring 11, the mixing tank 10 will gradually rotate with the rotation of the gear 7. Through the cooperation of the guide wheel 8 and the limiting groove 12, the mixing process is more stable, so that the concrete inside is evenly mixed;

[0043] At the same time, during the mixing process, the mixer will vibrate. At this time, after the controller body 16 is vibrated, it will squeeze the two fixed blocks 173 to move closer to the fixed block 171, so that the connecting rod 174 and the connecting rod 172 will rotate. Through the rotation of the connecting rod 174 and the connecting rod 172, the two sliding blocks 175 will be pushed to gradually approach and squeeze the spring 177 in the internal cavity of the shell 176. Through the contraction of the spring 177 and the buffering of the damper 18, the vibration of the controller body 16 is greatly reduced, and the internal parts of the controller body 16 are prevented from loosening and being damaged due to long-term vibration. The service life of the controller body 16 and the mixer is effectively improved. Among them, through the heat dissipation holes 19 on both sides, the interior of the control box 14 can be effectively ventilated and cooled, and the internal temperature of the control box 14 is prevented from being high, which affects the operation and service life of the controller body 16.
