Abstract
Description
Technical Field
[0001] The present application relates to the technical field of concrete construction, and in particular to a concrete anti-stationary transportation device. Background Art
[0002] During concrete construction, concrete needs to be transported to the construction area using transport equipment. Currently, large concrete transport vehicles have a mixing function during transportation. However, when filling and repairing damaged areas of concrete-paved roads or working in small construction areas and corners, small carts are needed to transport concrete supplementary materials. These concrete supplementary materials are easily left standing in the carts, affecting the use effect of the concrete.
[0003] In this regard, the patent with announcement number CN218779281U discloses "an asphalt concrete anti-stationary transportation device, which relates to the technical field of concrete transportation equipment, including: a transport cart; a storage box for storing asphalt concrete, which is installed on the transport cart. The utility model uses a small cart to transport asphalt concrete supplementary materials to fill and repair damaged areas of the road or to carry out construction in small construction areas and corner areas. It effectively avoids the asphalt concrete supplementary materials from standing still in the cart, which affects the use effect of the asphalt concrete. At the same time, it effectively avoids the asphalt concrete from adhering to the cart, which makes it inconvenient to clean the cart."
[0004] Regarding the above-mentioned related technologies, the inventors believe that after the sealing plate is opened, the concrete will flow out quickly from one side of the storage box, making it impossible to control the amount of concrete. When the discharged concrete exceeds the required amount in the repair or construction area, the excess concrete needs to be manually shoveled back into the storage box through the feed port, which is time-consuming and labor-intensive. Utility Model Content
[0005] In order to solve the above problems, the present application provides a concrete anti-stationary transportation device.
[0006] The present application provides a concrete anti-stationary transportation device that adopts the following technical solutions:
[0007] A concrete anti-stagnation transport device includes a movable transport tank, a stirring mechanism installed in the transport tank and used to stir concrete to prevent stagnation, and a conveying mechanism installed in the transport tank and used to quantitatively convey concrete. A discharge pipe is fixedly provided on one side of the bottom of the transport tank. The conveying mechanism includes a second rotating rod rotatably installed in the discharge pipe, and a spiral blade fixedly installed at one end of the second rotating rod. The spiral blade is rotatably connected to the corresponding discharge pipe.
[0008] The bottom of the transport tank is provided with a driving mechanism for driving the stirring mechanism and the conveying mechanism to rotate, and the driving mechanism includes a motor fixed at the center of the bottom of the transport tank, and a transmission mechanism arranged between the motor, the stirring mechanism and the conveying mechanism. The top of the transport tank is provided with an indicator for indicating the direction of the motor as the stirring mechanism rotates, and the bottom of the indicator is fixed with bristles that cooperate and abut against the top of the outer wall of the transport tank.
[0009] By adopting the above technical solution, the concrete can be quantitatively transported by utilizing the rotation of the spiral blades in the conveying mechanism, so that the device can quantitatively discharge the concrete according to the required amount of concrete at the construction site.
[0010] Preferably, a plurality of casters are fixedly installed at the bottom edge of the transport tank, a feed hopper is fixedly provided on one side of the top of the transport tank, and the stirring mechanism includes a first rotating rod rotatably arranged in the transport tank and coaxial with the transport tank, a rotating plate fixed on the outer wall of the bottom end of the first rotating rod for pushing the concrete at the bottom inside the transport tank, and a stirring blade fixed on the middle of the outer wall of the first rotating rod for stirring the concrete in the transport tank, and a scraper fixed on the outer wall of the first rotating rod for cooperating and abutting against the inner wall of the transport tank.
[0011] By adopting the above technical solution and arranging the rotating plate and the stirring blades in the stirring mechanism, the concrete in the transport tank can be stirred to prevent the concrete from being statically stratified in the transport tank.
[0012] Preferably, a protective box located between the rotating plate and the scraper is fixedly provided at the bottom of the inner wall of the transport tank, the end of the second rotating rod facing away from the spiral blade is rotatably connected in the protective box, the motor is located outside the transport tank, the first rotating rod is fixed at the top of the output end of the motor, the transmission mechanism includes a first bevel gear fixed to the outside of the first rotating rod, and a second bevel gear meshingly connected to one side of the bottom of the first bevel gear, the second bevel gear is fixed to the outer wall of one end of the second rotating rod, and the first bevel gear and the second bevel gear are both located inside the protective box.
[0013] By adopting the above technical solution, the forward rotation of the motor, in conjunction with the transmission of the transmission mechanism, can drive the mixing mechanism to rotate to stir the concrete to prevent it from settling, and can also drive the spiral blades to quantitatively discharge the concrete.
[0014] Preferably, the top end of the first rotating rod passes through and extends to the outside of the transport tank, the indicator is fixed on the outer wall of the top end of the first rotating rod, and a handle for people to push the device to move is fixed on one side of the transport tank.
[0015] By adopting the above technical solution, the indicator can indicate the rotation direction of the motor to the user, thereby preventing the user from mistakenly operating the concrete before reaching the construction area due to being unable to observe the rotation direction of the motor.
[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] 1. The rotation of the spiral blades in the conveying mechanism can quantitatively convey concrete, so that the device can quantitatively discharge concrete according to the required amount of concrete at the construction site, avoiding the trouble of manually shoveling excess concrete back into the transport tank at a later stage. The setting of the rotating plate and stirring blades in the mixing mechanism can stir the concrete in the transport tank to prevent the concrete from standing and stratifying in the transport tank, thereby improving the quality of concrete in use;
[0018] 2. The forward rotation of the motor can drive the mixing mechanism to rotate to stir the concrete to prevent it from settling, and can also drive the spiral blades to quantitatively discharge the concrete. The reverse rotation of the motor can cause the spiral blades to transport the concrete in the reverse direction, making it impossible for the concrete in the transport tank to be discharged. This ensures that the two processes of stirring the concrete and quantitatively discharging the concrete do not interfere with each other.
[0019] 3. With the help of the indicator, the direction of rotation of the motor can be shown to the user, avoiding the user's mistaken operation due to the inability to observe the direction of the motor and discharging the concrete before reaching the construction area. The bristles can clean the top of the transport tank when the indicator rotates, reducing the intensity of people's cleaning of the transport tank in the later stage.

DETAILED DESCRIPTION
[0025] The following is combined with Figure 1-Figure 4 This application is described in further detail.
[0026] The embodiment of the present application discloses a concrete anti-stationary transportation device.
[0027] Example 1
[0028] Reference Figure 1-4 A concrete anti-stationary transportation device includes a movable transportation tank 1, a stirring mechanism and a conveying mechanism.
[0029] The transport tank 1 is in the shape of a round tank, and a number of casters 13 are fixedly installed on the bottom edge of the transport tank 1. A feed hopper 12 is fixedly provided on the top side of the transport tank 1, and a discharge pipe 11 is fixedly provided on the bottom side of the transport tank 1. People can push the transport tank 1 to move by rotating the casters 13, and equipment such as concrete tankers can feed concrete into the transport tank 1 through the feed hopper 12, so that people can push the transport tank 1 to the construction area where equipment such as concrete tankers are inconvenient to reach or where the demand for concrete is small. When the transport tank 1 arrives at the construction area, the concrete can be discharged through the discharge pipe 11 to repair the roads in the construction area or to carry out concrete construction in the corner areas.
[0030] Reference Figure 1-2 The conveying mechanism includes a second rotating rod 3 rotatably arranged in the discharge pipe 11, and a spiral blade 31 fixed at one end of the second rotating rod 3. The spiral blade 31 is rotatably connected to the corresponding discharge pipe 11. After the second rotating rod 3 is running, it will drive the spiral blade 31 to rotate. After the spiral blade 31 rotates forward, it will quantitatively convey the concrete in the transport tank 1 through the discharge pipe 11 to carry out quantitative discharge. After the spiral blade 31 is reversed, it will reversely convey the concrete in the discharge pipe 11 into the transport tank 1, so that the concrete in the transport tank 1 cannot be discharged through the discharge pipe 11.
[0031] Reference Figure 2 The mixing mechanism includes a first rotating rod 2 that is rotatably arranged in the transport tank 1 and coaxial with the transport tank 1, a rotating plate 21 fixed on the outer wall of the bottom end of the first rotating rod 2 for pushing the concrete at the bottom inner side of the transport tank 1, and a mixing blade 22 fixed on the middle of the outer wall of the first rotating rod 2 for stirring the concrete in the transport tank 1. The rotating plate 21 is in contact with the bottom of the inner wall of the transport tank 1. When the first rotating rod 2 rotates, it will drive the rotating plate 21 and the mixing blade 22 to rotate. When the rotating plate 21 rotates, it will push the concrete at the bottom inner side of the transport tank 1. When the mixing blade 22 rotates, it can stir and agitate the concrete in the transport tank 1, thereby preventing the concrete from standing and stratifying in the transport tank 1 and improving the quality of the concrete.
[0032] Reference Figure 2 A scraper 23 is fixedly provided on the outer wall of the first rotating rod 2 for cooperating with the inner wall of the transport tank 1. After the first rotating rod 2 is running, it will drive the scraper 23 to rotate. After the scraper 23 is running, it will scrape off a large area of concrete adhering to the inner wall of the transport tank 1, reducing the difficulty and intensity of people's later cleaning of the transport tank 1.
[0033] Reference Figure 1-2 A driving mechanism for driving the stirring mechanism and the conveying mechanism to rotate is provided at the bottom of the transport tank 1. The driving mechanism includes a motor 4 fixed at the center of the bottom of the transport tank 1, and a transmission mechanism provided between the motor 4, the stirring mechanism and the conveying mechanism. The motor 4 can rotate forward and reverse, which is a prior art and will not be elaborated on here. The motor 4 can drive the stirring mechanism and the conveying mechanism to rotate through the transmission of the transmission mechanism.
[0034] Reference Figure 2-3 A protective box 41 is fixedly provided at the bottom of the inner wall of the transport tank 1, and is located between the rotating plate 21 and the scraper 23. The end of the second rotating rod 3 facing away from the spiral blade 31 is rotatably connected to the protective box 41. The protective box 41 can support and limit the second rotating rod 3. The protective box 41 consists of a long plate fixed on the inner wall of the transport tank 1 and a box body fixed on one side of the long plate.
[0035] Reference Figure 2-3 The motor 4 is located outside the transport tank 1, and the first rotating rod 2 is fixed at the top of the output end of the motor 4. The transmission mechanism includes a first bevel gear 42 fixed to the outside of the first rotating rod 2, and a second bevel gear 43 meshingly connected to one side of the bottom of the first bevel gear 42. The second bevel gear 43 is fixed to the outer wall of one end of the second rotating rod 3. The first bevel gear 42 and the second bevel gear 43 are both located inside the protective box 41. The box body of the protective box 41 can hide and protect the first bevel gear 42 and the second bevel gear 43.
[0036] After the motor 4 is running, it will drive the first rotating rod 2 and the first bevel gear 42 to rotate, and cooperate with the engagement of the first bevel gear 42 and the second bevel gear 43 to drive the second rotating rod 3 to rotate. After the motor 4 rotates forward and reverse, the stirring mechanism will also rotate forward and reverse. After the forward and reverse rotation, the stirring mechanism will stir the concrete in the transport tank 1 to prevent it from stagnation.
[0037] Reference Figure 1 、 Figure 2 and Figure 4 An indicator 5 is provided on the top of the transport tank 1 for indicating the direction of the motor 4 as the stirring mechanism rotates. A brush 51 is fixed to the bottom of the indicator 5 and is in contact with the top of the outer wall of the transport tank 1. The top of the first rotating rod 2 passes through and extends to the outside of the transport tank 1. The indicator 5 is fixed to the outer wall of the top of the first rotating rod 2. A handle is fixed on one side of the transport tank 1 for people to push the device to move. People can push the transport tank 1 by holding the handle.
[0038] After the first rotating rod 2 rotates, it can drive the indicator 5 and the brush 51 to rotate, so that people can judge the rotation direction of the motor 4 by observing the rotation direction of the indicator 5 outside the transport tank 1, thereby preventing users from mistakenly operating the concrete before reaching the construction area due to being unable to observe the direction of rotation of the motor 4. After the brush 51 rotates, it can clean the top of the transport tank 1, reducing the intensity of people's cleaning of the transport tank 1 in the later stage.
[0039] The implementation principle of the concrete anti-stationary transportation device of the embodiment of the present application is as follows: when in use, the user can push the device to move and control the rotation of the motor 4 to drive the first rotating rod 2, the rotating plate 21, the mixing blade 22, the scraper 23, the indicator 5 and the bristles 51 to rotate. After the first rotating rod rotates, the first bevel gear 42 and the second bevel gear 43 in the transmission mechanism are engaged, thereby driving the second rotating rod 3 and the spiral blade 31 to rotate;
[0040] After the motor 4 is reversed, it will drive the rotating plate 21, the mixing blade 22, and the scraper 23 to rotate in the opposite direction when the transport tank 1 is transported. After the rotating plate 21 rotates, it will push the concrete at the bottom of the inner side of the transport tank 1. After the scraper 23 runs, it will scrape off a large area of concrete adhering to the inner wall of the transport tank 1. After the mixing blade 22 rotates, it can stir and agitate the concrete in the transport tank 1, thereby preventing the concrete from standing and stratifying in the transport tank 1 and improving the quality of the concrete. After the spiral blade 31 is reversed, it will transport the concrete in the discharge pipe 11 back to the transport tank 1, so that the concrete in the transport tank 1 cannot be discharged through the discharge pipe 11.
[0041] When the transport tank 1 arrives at the construction site, the motor 4 can be controlled to rotate forward during use. The turn plate 21, the mixing blade 22, and the scraper 23 will still stir the concrete after rotating forward. The spiral blade 31 will quantitatively transport the concrete in the transport tank 1 through the discharge pipe 11 after rotating forward to carry out quantitative discharge. When the concrete discharged by the device reaches the required amount, the user can turn off the motor 4 and transport the device to the next construction site to continue the quantitative discharge of concrete.
[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
