Generally, it is stored in a commercial concrete mixing tank, and a discharge pipe is generally provided at the bottom of the commercial concrete mixing tank and a valve is installed on the discharge pipe. However, its stirring structure generally only stirs the inside of the commercial concrete mixing tank. Therefore, the commercial concrete remaining in the discharge pipe and above the valve is prone to solidification. Therefore, it is difficult to discharge the commercial concrete, and the commercial concrete mixing tank is easily scrapped as a whole. For this reason, an anti-solidification device based on commercial concrete mixing is designed. Utility Model Content

[0021] See also Figure 1-3 , an anti-solidification device based on commercial concrete mixing, comprising a commercial concrete mixing tank 1 with a discharge pipe 2 fixedly connected to the bottom, a stirring mechanism arranged in the commercial concrete mixing tank 1, the stirring mechanism being in contact with the inner wall of the commercial concrete mixing tank 1, and comprising a blocking slide 6 which can be sealingly slidably matched with the discharge pipe 2 and whose top wall is adapted to the inner wall of the commercial concrete mixing tank 1, an elastic mechanism which can make the upper part of the blocking slide 6 in a free state push into the commercial concrete mixing tank 1 is arranged below the discharge pipe 2, a magnetic repulsion mechanism adapted to the blocking slide 6 is fixedly connected to the position of the stirring mechanism at the discharge pipe 2, when the magnetic repulsion mechanism moves to the discharge pipe 2 with the rotation of the stirring mechanism, The blocking slide 6 can be magnetically repelled into the discharge pipe 2 and the top surface of the blocking slide 6 and the inner wall surface of the commercial concrete mixing tank 1 are in a smooth surface. It also includes a lifting mechanism that can drive the blocking slide 6 and the elastic mechanism to drop as a whole until the blocking slide 6 is separated from the bottom of the discharge pipe 2. Furthermore, a plurality of brackets 18 are fixedly installed at the bottom of the commercial concrete mixing tank 1, a feeding port is opened at the top of the commercial concrete mixing tank 1, and a feeding hopper 19 is fixedly installed at the feeding port. The bracket 18 is convenient for supporting the commercial concrete mixing tank 1. Through the setting of the feeding hopper 19, it is convenient to add raw materials or commercial concrete for preparing commercial concrete into the commercial concrete mixing tank 1 through the feeding port.
[0022] Specifically, the stirring mechanism includes a rotating shaft 3 rotatably connected to the commercial concrete mixing tank 1, a stirring screw belt 4 in contact with the inner wall of the commercial concrete mixing tank 1 is fixedly connected to the rotating shaft 3, and also includes a stirring motor 5 fixedly installed on the outside of the commercial concrete mixing tank 1 and used to drive the rotating shaft 3 to rotate. Starting the stirring motor 5 is convenient to drive the rotating shaft 3 and the stirring screw belt 4 to rotate as a whole. The stirring screw belt 4 is convenient for stirring the commercial concrete in the commercial concrete mixing tank 1 and also for scraping the commercial concrete on the inner wall of the commercial concrete mixing tank 1.
[0023] Specifically, the magnetic repulsion mechanism includes a magnetic strip 17 embedded and fixedly mounted on the stirring screw belt 4, and the sealing slide 6 is configured to be a material that magnetically repels the magnetic strip 17. Through the cooperation between the magnetic strip 17 and the sealing slide 6, as the magnetic strip 17 approaches the sealing slide 6, the sealing slide 6 can be pushed downward.
[0024] Specifically, a U-shaped fixing bar 7 fixedly connected to the commercial concrete mixing tank 1 is provided below the discharge pipe 2, a guide column 8 extending into the discharge pipe 2 is fixedly connected to the U-shaped fixing bar 7, and the top surface of the guide column 8 and the inner wall of the commercial concrete mixing tank 1 are in a smooth surface, a through hole for guiding and slidingly cooperating with the guide column 8 is provided on the blocking slide 6, an L-shaped slide bar 9 is fixedly connected to the bottom of the blocking slide 6, and the L-shaped slide bar 9 is guided and slidably cooperating with the U-shaped fixing bar 7, a fixing block 10 is provided on the commercial concrete mixing tank 1, an elastic mechanism is provided between the fixing block 10 and the L-shaped slide bar 9, and the elastic mechanism includes a lower spring 14 and an upper spring 15, and the bottom of the fixing block 10 is fixedly connected to a fixing rod for vertically slidingly cooperating with the L-shaped slide bar 9 12, the bottom of the fixed rod 12 is fixedly connected to the limit plate 13, the upper spring 15 and the lower spring 14 are both sleeved on the fixed rod 12 and are respectively arranged on the upper and lower sides of the L-shaped slide bar 9, and the two ends of the lower spring 14 are respectively fixedly connected to the fixed rod 12 and the L-shaped slide bar 9, and the two ends of the upper spring 15 are respectively fixedly connected to the fixed block 10 and the L-shaped slide bar 9. In the free state, the lower spring 14 is compressed and the upper spring 15 is stretched. When the blocking slide plate 6 is lowered, the lower spring 14 can be further compressed and the upper spring 15 can be further stretched. When the downward pressure on the blocking slide plate 6 is released, under the action of the rebound force of the lower spring 14 and the upper spring 15, the blocking slide plate 6 rises to the upper part of the blocking slide plate 6 and extends into the commercial concrete mixing tank 1.
[0025] Specifically, the lifting mechanism includes a lifting drive cylinder 11 vertically fixedly installed on the U-shaped fixing bar 7, and the bottom output end of the lifting drive cylinder 11 is fixedly connected to the fixed block 10. Through the lifting drive cylinder 11, it is convenient to drive the fixed block 10 and the L-shaped slide bar 9 and the blocking slide plate 6 connected by the elastic mechanism to perform lifting and lowering movements as a whole. When the output shaft of the lifting drive cylinder 11 is extended, the fixed block 10, the L-shaped slide bar 9 and the blocking slide plate 6 are lowered as a whole to a state where the blocking slide plate 6 is detached from the bottom of the discharge pipe 2, so that the commercial concrete in the commercial concrete mixing tank 1 can be discharged through the discharge pipe 2.
[0026] Specifically, the L-shaped slide bar 9 is slidably matched with the inner wall of the discharge pipe 2, and a guide rod 16 is fixedly connected to the L-shaped slide bar 9 and is vertically guided and slidably matched with the U-shaped fixing bar 7. Through the sliding cooperation between the L-shaped slide bar 9 and the discharge pipe 2 and the setting of the guide rod 16, the stability of the overall lifting and lowering of the L-shaped slide bar 9 is increased, and the stability of the lifting and lowering of the blocking slide plate 6 is further guaranteed.
[0027] When in use, the stirring mechanism is started, and the stirring mechanism stirs the commercial concrete in the commercial concrete mixing tank 1. When the magnetic repulsion mechanism on the stirring mechanism moves to the discharge pipe 2 with the rotation of the stirring mechanism, the blocking slide 6 is pushed down until the top surface of the blocking slide 6 and the inner wall of the commercial concrete mixing tank 1 are in a smooth surface. As the stirring proceeds, the commercial concrete on the top of the blocking slide 6 is scraped off by the magnetic repulsion mechanism, and the stirring is synchronously performed with the stirring of the stirring mechanism. When the magnetic repulsion mechanism leaves, the blocking slide 6 is moved up under the action of the rebound force of the elastic mechanism. In this way, the blocking slide 6 can be reciprocated and lifted at the connection between the commercial concrete mixing tank 1 and the discharge pipe 2. At the same time, the blocking is ensured while the blocking slide 6 is kept in an active state to avoid solidification. By setting a lifting mechanism, the blocking slide 6 and the elastic mechanism can be driven to descend as a whole until the blocking slide 6 is separated from the bottom of the discharge pipe 2, so that the discharge operation of the commercial concrete can be performed.
