Description

Technical Field

[0001] The present invention relates to the field of concrete pouring, and more particularly to a concrete pouring device. Background Art

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.

[0003] A pouring device is used when pouring concrete. The authorization announcement number is CN211498384U. A pouring device for recycled aggregate concrete is used to stir the concrete through a stirring device, and the material is discharged out of the machine body from the discharge port through a discharging device. When the piston slides upward, the valve on the pipe connecting the piston cylinder and the mixing cylinder needs to be opened to allow the concrete to enter the discharging device, but it takes a certain amount of time to allow a sufficient amount of concrete to enter the discharging device. Therefore, the time interval between two discharges is large, which will lead to reduced pouring efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a concrete pouring device, which can shorten the time of two discharges and improve the pouring efficiency.

[0029] The present invention has at least the following beneficial effects:

[0030] In the present invention, the power is used to drive the extrusion plate to move upward, and the moving plate is manually moved upward to allow the concrete to enter below the extrusion plate and the moving plate. Then, the power drives the extrusion plate to move downward, pushing the concrete to be discharged from the concrete discharge pipe. During this process, part of the concrete is squeezed by the extrusion plate below the moving plate, and the concrete conveyed by the auger conveyor is also conveyed below the moving plate. After the extrusion plate moves to the bottommost position, the power drives the extrusion plate to move upward, and the moving plate is manually pressed downward. The concrete below the moving plate and the concrete conveyed by the auger conveyor can be quickly squeezed below the extrusion plate. Then, the power drives the extrusion plate to move downward, pushing the concrete to be discharged from the concrete discharge pipe. In this way, the time between two discharges can be shortened, ensuring the continuous operation of the auger conveyor.

[0031] By setting a fixed pulley, a connecting rope and a counterweight block in the present invention, when the extrusion plate moves downward, it can drive the moving plate to move upward. When the extrusion plate moves upward, under the action of the counterweight block, the moving block can push the concrete below it, thus saving manpower.

[0032] The present invention drives the mixing of concrete and the rotation of the sector gear through the same driving device, which can save costs.

[0033] Other advantages, objectives, and features of the present invention will be partially reflected in the following description and partially understood by those skilled in the art through the research and practice of the present invention. Description of the Drawings

[0036] The following further describes the present invention in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0037] It should be noted that in the description of the present invention, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0038] As Figure 1 shown, the present invention provides a concrete pouring device, including:

[0039] A mixing tank 1, with a concrete outlet provided at its bottom. The mixing tank 1 is a mixing tank in the prior art with a concrete outlet at the bottom;

[0040] A screw conveyor 2, which is provided at the bottom of the mixing tank 1. The inlet of the screw conveyor 2 is connected to the concrete outlet of the mixing tank 1 to convey the mixed concrete;

[0041] An extrusion box 3, which is a cuboid with a hollow interior. A discharge pipe 301 is provided at the bottom of the extrusion box 3. The extrusion box 3 includes a first side wall, a second side wall, a third side wall, and a fourth side wall. The first side wall (as Figure 1 shown, the side wall of the extrusion box 3 on the right side) and the fourth side wall (as Figure 1 shown, the side wall of the extrusion box 3 on the left side) are both located between the second side wall and the third side wall. A first opening is provided on the first side wall, and the discharge outlet of the screw conveyor 2 is connected to the first opening;

[0042] The extrusion plate 4 is L-shaped and includes a horizontal portion and a vertical portion. The vertical portion of the extrusion plate 4 is parallel to the first side wall and is spaced apart by a certain distance. The horizontal portion of the extrusion plate 4 is in contact with the second side wall, the third side wall, and the fourth side wall. The extrusion plate 4 moves up and down under the drive of power and always remains at a certain distance from the top of the extrusion box 3; the discharge pipe 301 faces the extrusion plate 4;

[0043] The moving plate 5 is square, and the four sides of the moving plate 5 are respectively in contact with the first side wall, the second side wall, the third side wall, and the vertical portion of the extrusion plate 4;

[0044] The first guide rod 6 is vertically arranged. The bottom of the first guide rod 6 is connected to the top of the moving plate 5, and the top passes through the top of the extrusion box 3 and extends to the outside of the extrusion box 3.

[0045] When the concrete pouring device provided by this solution is in use, the extrusion plate 4 is driven by power to move upward, and the moving plate 5 is manually moved upward to allow the concrete to enter below the extrusion plate 4 and the moving plate 5. Then, the extrusion plate 4 is driven by power to move downward, pushing the concrete to be discharged from the concrete discharge pipe 301. During this process, part of the concrete is squeezed by the extrusion plate 4 below the moving plate 5, and the concrete conveyed by the auger conveyor 2 is also conveyed below the moving plate 5. After the extrusion plate 4 moves to the bottommost position, the extrusion plate 4 is driven by power to move upward, and the moving plate 5 is manually pressed downward. The concrete below the moving plate 5 and the concrete conveyed by the auger conveyor 2 can be quickly squeezed below the extrusion plate 4. Then, the extrusion plate 4 is driven by power to move downward, pushing the concrete to be discharged from the concrete discharge pipe 301. This can shorten the time between two discharges and ensure the continuous operation of the auger conveyor 2. During the upward movement of the moving plate 5, it is always in contact with the first side wall, the second side wall, the third side wall, and the vertical portion of the extrusion plate 4 to prevent the concrete from flowing above the extrusion plate 4 and the moving plate 5.

[0046] Specifically, the bottom of the first guide rod is connected to the center of the top of the moving plate. The first guide rod is rectangular parallelepiped-shaped and is coaxially arranged with the moving plate;

[0047] The concrete pouring device further includes:

[0048] A fixed pulley 7 is arranged above the extrusion box 3;

[0049] A connecting rope 8, one end of which is connected to the extrusion plate 4, the other end passes through the top of the extrusion box 3, bypasses the fixed pulley 7, and is connected to the top of the first guide rod 6. The other end of the connecting rope 8 is in a straight line with the first guide rod 6. When the extrusion plate 4 moves up and down under the drive of power, the connecting rope 8 can drive the first guide rod 6 to move up and down, thereby driving the moving plate 5 to move up and down;

[0050] The counterweight 9 is square, sleeved on the first guide rod and coaxially arranged with the first guide rod.

[0051] In this solution, by setting the fixed pulley 7 and the connecting rope 8, when the pressing plate 4 moves downward, the moving plate 5 can be driven to move upward synchronously. By setting the counterweight 9, when the pressing plate 4 moves upward, under the action of the gravity of the counterweight 9, the moving plate 5 can push the concrete below it, thus saving manpower.

[0052] Specifically, as Figure 2 shown, it further includes:

[0053] The driving box 10 has a hollow interior and is arranged above the extrusion box 3. Two guide blocks 101 are arranged at intervals in the vertical direction on one side wall of the driving box 10; a linear bearing can be arranged between the guide block 101 and the second guide rod 111 to make the movement of the second guide rod 111 smoother.

[0054] The moving assembly 11 includes two second guide rods 111 and a rack assembly 112. The two second guide rods 111 respectively pass vertically through the two guide blocks. The second guide rod 111 located below passes through the bottom of the driving box 10 and the top of the extrusion box 3 in sequence and then is connected to the horizontal part of the pressing plate 4. The second guide rod 111 located above passes through the top of the driving box 10. The rack assembly 112 is located between the two second guide rods 111. The bottom of the second guide rod 111 located above is connected to the top of the rack assembly 112, and the top of the second guide rod 111 located below is connected to the bottom of the rack assembly 112. The rack assembly 112 is frame-shaped and has two vertical and oppositely arranged racks; the two second guide rods 111 are always guided by their respective corresponding guide blocks during the movement.

[0055] The sector gear 12 rotates under the drive of power. The sector gear 12 is arranged between the two racks and alternately meshes with the two racks. When the sector gear 12 rotates, it continuously drives the moving assembly 11 to move up and down, so that the pressing plate 4 moves up and down under the drive of power.

[0056] Through the cooperation of the sector gear 12 and the rack assembly 112, when the sector gear 12 rotates under the drive of power, it can continuously drive the moving assembly 11 to move up and down, and can make the pressing plate 4 move up and down under the drive of power.

[0057] Specifically, a limit block 61 is arranged on the first guide rod 6. When the pressing plate 4 moves downward until its horizontal part fits with the bottom of the extrusion box 3 and the limit block 61 fits with the top of the extrusion box 3, the height of the moving plate 5 is not higher than the height of the top of the vertical part of the pressing plate 4. This can prevent the moving plate 5 from moving upward above the vertical part of the pressing plate 4. When the limit block 61 fits with the top of the extrusion box 3, the moving plate 5 moves to the highest position.

[0058] Specifically, a rotating shaft 13 is provided on the sector gear 12. The rotating shaft 13 passes through the driving box 10 and is rotatably connected to the driving box 10. When the rotating shaft 13 rotates, it drives the sector gear 12 to rotate synchronously. One end of the rotating shaft 13 away from the sector gear 12 is provided with a first bevel gear 14. The top of the rotating shaft 13 of the mixing tank 1 passes through the top of the mixing tank 1 and is connected to the driving device. A second bevel gear 15 meshing with the first bevel gear 14 is provided on the rotating shaft 13 of the mixing tank 1. Both the first bevel gear and the second bevel gear are located above the mixing tank 1. The driving device drives the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 can drive the second bevel gear 15 to rotate. At the same time, the rotation of the second bevel gear 15 drives the first bevel gear 14 meshing with it to rotate, thereby driving the rotating shaft 13 to rotate and causing the sector gear 12 to rotate. This solution drives the mixing of concrete and the rotation of the sector gear 12 through the same driving device, which can save costs.

[0059] Specifically, the rack assembly 112 is in a square frame shape, and the two second guide rods 111 are both symmetrically arranged with respect to the axis of the rack assembly 112.

[0060] Specifically, it further includes:

[0061] A box body 16, with a second opening provided at its bottom. The discharge pipe 301 passes through the second opening and extends below the box body 16. The mixing tank 1, the auger conveyor 2, the extrusion box 3, and the driving box are all located inside the box body 16 and are fixed on the box body 16.

[0062] Specifically, a plurality of universal wheels are provided at the bottom of the box body 16. A flattening roller can also be provided at the bottom of the box body 16 to enable pouring and flattening to be carried out simultaneously.

[0063] Specifically, the fixed pulley 7 is fixed to the bottom of the driving box 10.

[0064] Specifically, the bottom of the lower second guide rod 111 is connected to the center of the top of the horizontal part of the extrusion plate 4.

[0065] Although the embodiments of the present invention have been disclosed as above, they are not limited to only the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated and described examples here.
