Description

Technical Field

[0001] This utility model relates to the field of concrete feeding technology, specifically a quantitative feeding device for concrete. Background Technology

[0002] With the trend of modern construction towards more refined processes, the demand for the production of various small concrete products (such as precast small components, decorative concrete ornaments, and building repair materials) and sporadic concrete work in construction projects is increasing. Unlike large-scale concrete pouring, the construction of small concrete components requires higher precision and flexibility in material delivery, often necessitating precise control of the amount of concrete delivered to ensure accurate component dimensions and meet appearance quality standards.

[0003] However, most existing concrete feeding devices are designed for large-scale continuous feeding and have obvious defects when dealing with small concrete components. Traditional feeding methods, such as manual scooping and simple hopper conveying, are not only inefficient, but also difficult to achieve precise quantitative feeding due to the differences in the fluidity and viscosity of the mixed concrete. This can easily lead to material waste or rework due to insufficient material, and cannot meet the usage requirements. Therefore, we propose a quantitative feeding device for concrete.

[0013] 1. When this utility model is in operation, the controller starts the first motor, which drives the active roller to rotate. With the cooperation of the driven roller, the active roller rotates and drives the conveyor belt to move, thereby moving the receiving box.

One side of the fixed frame 6 is fixedly connected to the support 1. A synchronous pulley 15 is fixedly connected to the output end of the second motor 12 and the right side of the rotating shaft 13. A synchronous belt 16 meshes with the surface of the synchronous pulley 15. A sliding rod is slidably connected to the inner cavity of the insert plate 11.

[0023] The specific function of this technical solution is as follows: During operation, the controller 23 starts the first motor 2, which drives the active roller 3 to rotate. With the cooperation of the driven roller 5, the active roller 3 rotates and drives the conveyor belt 4 to move, thereby moving the receiving box 8.

[0024] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 3As shown, a housing 25 is fixedly connected to the surface of the conveyor belt 4. A connecting shaft 17 is movably connected to one side of the housing 25 via a second bearing. A drive gear 18 is fixedly connected to one side of the connecting shaft 17. A driven gear 19 meshes with one side of the drive gear 18. A lead screw 20 is fixedly connected to the inner cavity of the driven gear 19. The front and back sides of the lead screw 20 are movably connected to the housing 25 via a third bearing. A rectangular plate 21 is threaded onto the surface of the lead screw 20. A pin 22 is fixedly connected to one side of the rectangular plate 21. A vertical plate 24 is inserted into the surface of the pin 22. One side of the vertical plate 24 is fixedly connected to the receiving box 8. Rectangular grooves are provided on the front and rear sides of the inner cavity of the housing 25, and the inner cavity of the rectangular grooves is slidably connected to the pin 22.

[0025] The specific function of this technical solution is as follows: Rotating the connecting shaft 17 causes the driving gear 18 to rotate, which in turn causes the driven gear 19 to rotate. The driven gear 19 then causes the lead screw 20 to rotate, which in turn causes the rectangular plate 21 to move. The rectangular plate 21 then causes the pin 22 to move. Once the pin 22 is away from the vertical plate 24, it can be used to replace the material box 8.

[0026] Working principle: During operation, the controller 23 starts the first motor 2, which drives the active roller 3 to rotate. With the cooperation of the driven roller 5, the active roller 3 rotates and drives the conveyor belt 4 to move, thereby moving the receiving box 8. After the receiving box 8 is aligned with the frame 9, the electric slide table 10 is started, which drives the insert plate 11 to move. As the insert plate 11 moves to the left, the material falls into the inner cavity of the receiving box 8. After the material fills the receiving box 8, the electric slide table 10 is started again, which makes the insert plate 11 return to its original position. Then the first motor 2 can be started again to adjust the empty receiving box 8 to the bottom of the frame 9. The second motor 12 can also be started. With the cooperation of the synchronous pulley 15 and the synchronous belt 16, the rotating shaft 13 can be driven to rotate. The rotating shaft 13 drives the stirring blade 14 to rotate, which avoids uneven distribution of material concentration.

[0027] Rotate the connecting shaft 17, which drives the drive gear 18 to rotate. The drive gear 18 drives the driven gear 19 to rotate. The driven gear 19 drives the lead screw 20 to rotate. The lead screw 20 drives the rectangular plate 21 to move. The rectangular plate 21 drives the pin 22 to move. After the pin 22 moves away from the vertical plate 24, it can be connected to the material box 8 for replacement.
