DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A large volume concrete mixing device for cold climates, such as Figure 1-6 As shown, it includes a fixing plate 100, a tank body 110 is installed on the upper end of the fixing plate 100, a knocking and anti-sticking wall assembly 120 is arranged above the tank body 110, and a spraying assembly 130 is arranged above the tank body 110 on the other side of the knocking and anti-sticking wall assembly 120;

[0027] The wall knocking and anti-sticking assembly 120 includes a motor 121 fixedly mounted on the upper end of the fixed plate 100, the output shaft of the motor 121 is installed with a stirring rod 122 that penetrates and extends to the inside of the tank body 110 through a coupling, the top of the stirring rod 122 is fixedly installed with a ratchet disk 123 extending from the outside of the tank body 110, the inner wall end bearing of the ratchet disk 123 is installed with a rotating block 124, the side wall of the rotating block 124 is rotatably installed with multiple groups of blocks 125 at the contact position with the inner wall surface of the ratchet disk 123, the other end of the rotating block 124 is fixedly installed with a connecting rod 126 located on the outside of the ratchet disk 123, the side wall of the rotating block 124 is fixedly installed with a first telescopic spring 127 fixed to the end of the block 125, and the other end of the connecting rod 126 is fixedly installed with a rotating Disk 128, a travel block 129 is installed on the upper end of the rotating disk 128, two groups of connecting blocks 1291 are fixedly installed at both ends of the side wall of the travel block 129, and multiple groups of tooth plates 1292 are fixedly installed at both ends of the side wall of each group of connecting blocks 1291. Four groups of first transmission rods 1294 close to both sides of the tooth plates 1292 are installed on the upper end bearing of the fixed plate 100, and the outer wall of each group of first transmission rods 1294 is fixedly installed with a gear 1293 at a surface contact position with the tooth plate 1292. The outer wall of the first transmission rod 1294 is fixedly installed with multiple groups of eccentric blocks 1295 at a surface contact position with the tank body 110. The outer wall of the first transmission rod 1294 is sleeved with a transmission belt 1296, and the inner wall of the transmission belt 1296 is sleeved with a second transmission rod 1297.

[0028] When the concrete attached to the inner wall of the tank body 110 is knocked to prevent adhesion, the motor 121 is started to cause the stirring rod 122 to rotate, and the concrete inside the tank body 110 can be evenly stirred. When the concrete attached to the inner wall of the tank body 110 is knocked and shaken off for cleaning, when the motor 121 is reversed, the clamping block 125 contacts the ratchet disk 123 under the telescopic force of the first telescopic spring 127, and the clamping force between the clamping block 125 and the ratchet disk 123 causes the connecting rod 126 and the rotating disk 128 to rotate in the opposite direction, completing the motor 121. When the motor 121 rotates forward, the rotating disk 128 does not rotate, and the rotating disk 128 rotates only when the motor 121 rotates reversely. When the rotating disk 128 rotates, it causes the travel block 129 to reciprocate on both sides, and during the movement, the tooth plate 1292 is prompted to contact the gear 1293 and drive the gear 1293 to rotate. When the gear 1293 rotates, it can prompt the multiple sets of eccentric blocks 1295 installed on the outer wall of the first transmission rod 1294 to rotate and knock the outer wall of the tank body 110, and the concrete attached to the inner wall of the tank body 110 can be caused to fall off through the knocking force.

[0029] Please refer to Figure 5 The spray assembly 130 includes a piston cylinder 131 fixedly mounted on the upper end of the tank body 110 and close to both sides of the connecting block 1291, a push rod 132 extending from the outside of the piston cylinder 131 and fixed to the end of the connecting block 1291 is slidably mounted inside the piston cylinder 131, a second telescopic spring 133 located at the bottom end of the piston cylinder 131 is fixedly mounted on the other end of the push rod 132, a water inlet pipe 134 is fixedly mounted on the side wall of the piston cylinder 131, a water storage tank 135 fixed to the end of the water inlet pipe 134 is fixedly mounted on the top of the tank body 110, and a drainage pipe 136 penetrating and extending to the inside of the tank body 110 is fixedly mounted on the other end of the piston cylinder 131.

[0030] When the concrete cleaned by beating the inner wall of the tank body 110 is sprayed, when the connecting rod 126 reciprocates on the left and right sides, the push rod 132 can be prompted to reciprocate inside the piston cylinder 131. When the push rod 132 moves to the left side inside the piston cylinder 131, the piston cylinder 131 replenishes the water flow inside the water storage tank 135 to the inside of the piston cylinder 131 through the water inlet pipe 134. After the replenishment is completed, the one-way valve in the water inlet pipe 134 is closed, and at the same time, when the push rod 132 moves to the right side inside the piston cylinder 131, the one-way valve in the drainage pipe 136 is opened, so that the water flow inside the piston cylinder 131 is sprayed to the inner wall of the tank body 110 through the drainage pipe 136, so that the inner wall of the tank body 110 can be washed and the knocking can be coordinated. While the inner wall of the tank body 110 is washed, the cleaning effect of the concrete attached to the inner wall of the tank body 110 can be further improved.

[0031] Please refer to Figure 2 and Figure 3The outer wall of the stirring rod 122 is located on the inner wall of the tank body 110 and a scraper is fixedly installed at a position in contact with the surface of the discharge trough.

[0032] By providing a scraper plate, the stirring rod 122 can scrape the concrete to the discharge trough when rotating, thereby avoiding blockage of the discharge trough.

[0033] Please refer to Figure 4 A one-way valve is provided at the connection position between the side wall of the piston cylinder 131 and the end of the water inlet pipe 134 and the drainage pipe 136.

[0034] The spraying of water flow is controlled by the one-way valves arranged inside the water inlet pipe 134 and the drainage pipe 136 .

[0035] Please refer to Figure 1 A collecting box located at the bottom of the tank body 110 is slidably mounted on the upper end of the fixing plate 100 .

[0036] The collection box can collect the concrete after the inner wall of the tank body 110 is cleaned.

[0037] Please refer to Figure 1 A feed port is provided on the side wall of the tank body 110 , and a feed box is fixedly mounted on the side wall of the tank body 110 at a position connected to the end of the feed port.

[0038] The material is put into the feed box and enters through the feed port.

[0039] When in use, when the concrete attached to the inner wall of the tank body 110 is knocked to prevent adhesion, the motor 121 is started, prompting the stirring rod 122 to rotate, and the concrete inside the tank body 110 can be evenly stirred. When the concrete attached to the inner wall of the tank body 110 is knocked and shaken off to be cleaned, when the motor 121 is reversed, the clamping block 125 contacts the ratchet disk 123 under the telescopic force of the first telescopic spring 127, and the clamping force between the clamping block 125 and the ratchet disk 123 prompts the connecting rod 126 and the rotating disk 128 to move. When the motor 121 rotates forward, the rotating disk 128 does not rotate, and the rotating disk 128 rotates only when the motor 121 rotates reversely. When the rotating disk 128 rotates, the travel block 129 makes a reciprocating movement on both sides, and when moving, the tooth plate 1292 is prompted to contact the gear 1293 and drive the gear 1293 to rotate. When the gear 1293 rotates, it can prompt the outer wall of the first transmission rod 1294 to install multiple sets of eccentric blocks 1295 to rotate and knock the outer wall of the tank body 110, and the knocking force can cause the tank to move. When the concrete attached to the inner wall of the tank body 110 falls off and the concrete cleaned by knocking on the inner wall of the tank body 110 is sprayed, when the connecting rod 126 reciprocates on the left and right sides, the push rod 132 can be prompted to reciprocate inside the piston cylinder 131. When the push rod 132 moves to the left inside the piston cylinder 131, the piston cylinder 131 replenishes the water flow inside the water storage tank 135 to the inside of the piston cylinder 131 through the water inlet pipe 134. After the replenishment is completed, the one-way valve in the water inlet pipe 134 is closed. At the same time, when the push rod 132 moves to the right inside the piston cylinder 131, the one-way valve in the drainage pipe 136 opens, causing the water flow inside the piston cylinder 131 to be sprayed into the inner wall of the tank body 110 through the drainage pipe 136, which can flush the inner wall of the tank body 110 and can be combined with knocking to further improve the cleaning effect of the concrete attached to the inner wall of the tank body 110 while flushing the inner wall of the tank body 110. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

[0040] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
