Description

Technical Field

[0001] This invention relates to the field of concrete transportation, and more specifically to a concrete anti-solidification device inside a concrete transport vehicle. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to concrete made by mixing concrete as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is also called ordinary concrete and is widely used in civil engineering. Concrete is characterized by abundant raw materials, low price, and simple production process, leading to its increasing usage. To prevent concrete from solidifying during transportation, large concrete mixer trucks are mostly used. However, in some rugged and narrow areas, large trucks cannot transport concrete, and handcarts or mortar trucks are usually used. However, when the concrete is transported over long distances, the exchange of air between the inside and outside of the concrete carries away a large amount of moisture, causing the concrete to gradually solidify, which is detrimental to construction. Therefore, a concrete anti-solidification device for the inside of concrete transport trucks is proposed. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention proposes a concrete anti-hardening device for the inside of a concrete transport vehicle, which prevents concrete from starting to set before use during long-term transportation and storage, thus rendering the concrete unusable.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A concrete anti-solidification device for a concrete transport vehicle includes: a storage box, a first mixing shaft, a second mixing shaft, and a mixing plate; the storage box is mounted on the transport vehicle; the first mixing shaft is rotatably connected to the inner side of the storage box; the second mixing shaft is rotatably connected to the inner side of the first mixing shaft; mixing seats are linearly and evenly distributed on the inner side of the first mixing shaft; each mixing seat is rotatably connected to a third mixing shaft; the mixing plate is fixedly mounted on the third mixing shaft; the mixing plate has evenly distributed perforations; the mixing plate is used to mix the concrete to prevent it from solidifying. Due to the high viscosity of concrete, some concrete is trapped within the flowing concrete during mixing, resulting in the concrete being fluid overall but not internally. However, by providing perforations, the trapped portion of the concrete passes through the perforations, thereby improving its fluidity and preventing solidification.

[0006] Each of the three stirring shafts is fixedly equipped with a bevel gear 1; each of the two stirring shafts is fixedly equipped with a bevel gear 2 on the side near the bevel gear 1; each bevel gear 1 meshes with the adjacent bevel gear 2; the conveyor is fixedly equipped with a motor 1 and a motor 2; the motor 1 drives the stirring shaft 1 through chain drive; the motor 2 drives the stirring shaft 2 through chain drive.

In this way, the bevel gear two on the mixing shaft two rotates relative to the bevel gear one, and the bevel gear two drives the bevel gear one and the mixing shaft three to rotate, thereby driving the mixing plate to rotate. The mixing plate rotates around the axis of the mixing shaft one and rotates around the mixing shaft two; through the through hole, the concrete passes through the center part, thereby improving its fluidity and preventing it from solidifying.

[0008] Fixed connections in this application refer to connections where parts or components do not move relative to each other after installation. Common examples include using screws, splines, or wedges to fix components together. This type of connection allows for disassembly during maintenance without damaging the parts.

These methods require forging, sawing, or oxy-acetylene cutting for disassembly during maintenance or replacement, so the parts are generally not reusable. Rotating connections in this application refer to connections where parts or components rotate relative to a fixed component after installation. Common forms include mounting bearings on the fixed component, with the part mounted on the inner or outer ring of the bearing, allowing rotational movement via the bearing. Sliding connections in this application refer to connections where parts or components can move on a fixed component after installation.

[0009] Furthermore, the storage tank is rotatably connected to a drive shaft at the upper end of the stirring shaft; the drive shafts are arranged in a matrix on the storage tank; a drive seat is installed inside the storage tank on each drive shaft; a nozzle is rotatably connected to the drive seat; the storage tank is provided with a delivery pipe; each nozzle is connected to the delivery pipe via a flexible hose; the transport vehicle is also provided with a water storage tank; a water pump is installed in the water storage tank; the water pump is connected to the delivery pipe; the drive shaft is provided with a sliding groove; a movable column is slidably connected to the sliding groove; a counterweight is fixedly installed on the side of each nozzle facing away from the movable column; the movable column is driven by a telescopic mechanism; the drive shaft is rotated by a four-wheel drive motor.

[0010] Furthermore, the storage box is also fixedly equipped with a screw seat and a connecting seat; the connecting seat is rotatably connected to a connecting shaft; both the connecting shaft and the drive shaft are fixedly equipped with sprockets; the sprockets are connected by a chain; the screw seat is rotatably connected to a screw; the screw seat is slidably connected to a movable block; the movable block is threadedly connected to the screw; the movable block is fixedly equipped with a push plate; the push plate abuts against the movable column; both the screw and the connecting shaft are fixedly equipped with bevel gears three; the motor four is disposed between the bevel gears three; the motor four is a double-headed motor; the motor four is equipped with two rotating columns through one-way bearings; the one-way bearings rotate in opposite directions; each rotating column is fixedly equipped with two toothed gears; the bevel gear three is disposed between the toothed gears; the toothed gears are adapted to the bevel gears three; each bevel gear three meshes with one of the toothed gears.

[0011] Furthermore, the storage tank is rotatably connected to an auger shaft; the auger shaft is fixedly mounted with auger blades; the auger shaft is driven by a third motor; the auger shaft is located at the lower end of the first stirring shaft; the transport vehicle is provided with a discharge port at the lower end of the auger shaft; and the feed port is located at the upper end of the storage tank.

[0012] Furthermore, the water storage tank is provided with two water storage chambers; each water storage chamber is connected to one of the water pumps; the delivery pipe is connected to both water pumps through a reversing valve.

[0013] Furthermore, a limiting shaft is fixedly installed on the side of the storage box near the chain; a tensioning wheel is rotatably connected to the limiting post; and the tensioning wheel abuts against the chain.

[0014] The beneficial effects of this invention are:

[0015] The concrete anti-solidification device inside the concrete transport vehicle of the present invention prevents concrete from solidifying by means of a mixing plate; by opening a hole in the mixing plate, the concrete in the center of the flowing concrete can be carried through the hole, thereby improving its fluidity and preventing it from solidifying.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] A concrete anti-solidification device for a concrete transport vehicle includes: a storage tank 1, a first mixing shaft 3, a second mixing shaft 4, and a mixing plate 7; the storage tank 1 is mounted on the transport vehicle; the first mixing shaft 3 is rotatably connected to the inner side of the storage tank 1; the second mixing shaft 4 is rotatably connected to the inner side of the first mixing shaft 3; mixing seats 5 are linearly and evenly distributed on the inner side of the storage tank 1 on the first mixing shaft 3; each mixing seat 5 is rotatably connected to a third mixing shaft 6; the mixing plate 7 is fixedly mounted on the third mixing shaft 6; the mixing plate 7 has through holes 8 evenly distributed; the mixing plate 7 is used to mix the concrete to prevent it from solidifying. Due to the high viscosity of concrete, some concrete is trapped within the flowing concrete during the mixing process, resulting in the concrete being flowing overall but not internally; however, by providing through holes 8, the trapped portion of the concrete passes through the through holes 8, thereby improving its fluidity and preventing solidification.

[0026] Each of the three stirring shafts 6 is fixedly equipped with a bevel gear 9; each of the two stirring shafts 4 is fixedly equipped with a bevel gear 10 on the side near the bevel gear 9; each bevel gear 9 meshes with the adjacent bevel gear 10; the conveyor is fixedly equipped with a motor 11 and a motor 12; the motor 11 drives the stirring shaft 3 through chain drive; the motor 12 drives the stirring shaft 4 through chain drive.

[0027] In use, first, the prepared concrete or unprepared concrete raw materials are placed into the storage box 1; then, motor 11 drives the mixing shaft 3 to rotate, causing the mixing shaft 3 to drive the mixing plate 7 to rotate, so that the mixing plate 7 can mix the prepared or unprepared concrete; then, motor 212 is started, and motor 212 drives the mixing shaft 24 to rotate, and the mixing shaft 24 rotates in the opposite direction to the mixing shaft 3 or at a different speed than the mixing shaft 3. In this way, the bevel gear 210 and bevel gear 19 on the mixing shaft 24 rotate relative to each other. The bevel gear 210 drives the bevel gear 19 and the mixing shaft 36 to rotate, thereby driving the mixing plate 7 to rotate. The mixing plate 7 rotates around the axis of the mixing shaft 3 and rotates around the mixing shaft 24; the concrete passes through the through hole 8 in the center part, thereby improving its fluidity and preventing it from solidifying.

[0028] Furthermore, a drive shaft 13 is rotatably connected to the upper end of the stirring shaft 3 in the storage tank 1; the drive shafts 13 are distributed in a matrix on the storage tank 1; a drive seat is installed inside the storage tank 1 on the drive shaft 13; a nozzle 14 is rotatably connected to the drive seat; the storage tank 1 is provided with a delivery pipe 16; all nozzles 14 are connected to the delivery pipe 16 through hoses 15; the transport vehicle is also provided with a water storage tank 17; a water pump 18 is installed in the water storage tank 17; the water pump 18 is connected to the delivery pipe 16; the drive shaft 13 is provided with a slide groove; a movable column 19 is slidably connected to the slide groove; a counterweight 20 is fixedly installed on the side of the nozzle 14 away from the movable column 19; the movable column 19 is driven by a telescopic mechanism, which can be a cylinder, an electric movable column 19, a hydraulic rod, etc.; the drive shaft 13 is driven to rotate by a motor 21.

[0029] During use, concrete inevitably adheres to the connection between the mixing shaft 6 and the mixing seat 5. Because of continuous mixing, it does not solidify during use. However, if not cleaned promptly after use, the concrete will stick to the mixing shaft 6 and the mixing seat 5. Therefore, a concrete solvent can be stored in the water storage tank 17. The solvent is then pumped through the water pump 18 to the delivery pipe 16 and hose 15, and finally sprayed onto the mixing plate 7 through the nozzle 14 to soften the concrete. A telescopic mechanism drives the movable column 19 to move, causing it to lift the nozzle 14 and adjust its angle. When the movable column 19 retracts, the nozzle 14 returns to its original position under the action of the counterweight 20. The motor 21 drives the drive shaft 13 to rotate, allowing the nozzle 14 to rotate around the drive shaft 13, thus adjusting the angle between the nozzle 14 and the movable rod. By adjusting these two angles, the spray surface of the nozzle 14 becomes conical. The interaction of multiple nozzles 14 effectively removes the concrete sticking to the mixing shaft 6 and the mixing seat 5.

[0030] Furthermore, the storage box 1 is also fixedly equipped with a screw seat and a connecting seat; the connecting seat is rotatably connected to a connecting shaft 22; both the connecting shaft 22 and the drive shaft 13 are fixedly equipped with sprockets; the sprockets are connected by a chain; the screw seat is rotatably connected to a screw 23; the screw seat is slidably connected to a movable block 24; the movable block 24 is threadedly connected to the screw 23; the movable block 24 is fixedly equipped with a push plate 25; the push plate 25 abuts against the movable column 19; both the screw 23 and the connecting shaft 22 are fixedly equipped with bevel gears 26; the motor 21 is mounted on the bevel gears. Between gear 3 26; motor 4 21 is a double-headed motor; motor 4 21 has two rotating columns 27 mounted on it via one-way bearings; the one-way bearings rotate in opposite directions, when motor 4 21 rotates in the forward direction it drives one rotating column 27 to rotate, and when motor 4 21 rotates in the reverse direction it drives the other rotating column 27 to rotate; each rotating column 27 has two toothed gears 28 fixedly mounted on it; bevel gear 3 26 is positioned between the toothed gears 28; the toothed gears 28 are adapted to bevel gear 3 26; each bevel gear 3 26 meshes with one toothed gear 28;

[0031] When motor 4 21 rotates once, it will drive a rotating column 27 to rotate. The two toothed gears 28 on the rotating column 27 will mesh with the bevel gear 3 26, thereby driving the bevel gear 3 26 to rotate in both directions. The bevel gear 3 26 drives the movable block 24 to move through the screw 23, thereby driving the push plate 25 to push the movable column 19 to move. The other bevel gear 3 26 drives the sprocket and chain to drive the drive shaft 13 to rotate through the connecting shaft 22.

[0033] Furthermore, the water storage tank 17 is provided with two water storage chambers; each water storage chamber is connected to a water pump 18; the delivery pipe 16 is connected to the two water pumps 18 through a reversing valve; one water storage chamber is used to store water, and the other is used to store solvent, and anti-coagulation agents can be added appropriately during the stirring process.
