Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a discharge mechanism for concrete production. Background Technology

[0002] Concrete is an artificial stone material made by mixing cementitious materials (such as cement), aggregates (sand, stone), water, and admixtures in a certain proportion, followed by stirring, molding, and curing. It features adjustable strength, good durability, high plasticity, and low cost, and is widely used in building construction (beams, slabs, columns, etc.), civil engineering (bridges, tunnels, dams), and special engineering (high-rise buildings, nuclear power plants), making it a core material in modern civil engineering. In the concrete production process, the discharge chamber of traditional mechanisms is usually fixedly connected to the machine body, and can only discharge in one direction. It is inconvenient to rotate the discharge chamber and difficult to flexibly adjust the discharge angle of concrete. When the position of the receiving equipment (such as a mixer truck or hopper) changes, it is necessary to move the equipment frequently or manually handle it, which not only increases the labor intensity, but also easily causes concrete to spill due to docking deviation, resulting in material waste and site pollution. If the discharge angle needs to be adjusted, it is often necessary to stop the machine and manually operate by disassembly and reassembly, which seriously interrupts the production process and greatly reduces production efficiency. Therefore, this utility model proposes a discharge mechanism for concrete production to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a discharge mechanism for concrete production, which solves the issues of inconvenience in rotating the discharge chamber and difficulty in flexibly adjusting the discharge angle of concrete in the prior art.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a discharge mechanism for concrete production, including a discharge chamber, a discharge pipe installed below the discharge chamber, a discharge pipe installed below the discharge chamber, a rotary joint installed at one end of the discharge pipe, the discharge pipe and the rotary joint being rotatably connected to each other, a first servo motor installed at one end of the discharge pipe, a screw conveyor shaft installed inside the discharge pipe, the output end of the first servo motor being connected to one end of the screw conveyor shaft, a discharge port opened on one side of the discharge pipe, mounting plates installed below both sides of the discharge chamber, a vibration mechanism provided above the mounting plates, and an adjustment mechanism provided below one of the mounting plates; The adjustment mechanism includes a mounting cavity, a self-locking motor, a driving gear, a driven gear, a transmission rod, a connecting rod, and a limiting structure. The mounting cavity is installed below a mounting plate. A self-locking motor is installed on one side of the top of the mounting cavity. A driving gear is installed on one side inside the mounting cavity. The output end of the self-locking motor is connected to one end of the driving gear. A driven gear meshes with one side of the driving gear. A transmission rod is installed at one end of the driven gear. A connecting rod is installed at the bottom end of the transmission rod. The bottom end of the connecting rod is connected to the top of the discharge pipe.

[0005] A further improvement is that the limiting structure includes a limiting rail and a limiting block. The limiting rail is installed on one side of the mounting cavity, and a limiting block is provided inside the limiting rail. The bottom end of the limiting block is connected to the top end of the transmission rod.

[0006] A further improvement is that the limiting rail and the limiting block are mutually adapted, and the limiting rail and the limiting block form a sliding structure.

[0007] A further improvement is that the limiting rail is designed in an arc shape, and the center of the limiting rail and the center of the driven gear are on the same straight line.

[0008] A further improvement is that the vibration mechanism includes a mounting base, a reciprocating cylinder, and a vibration block. The mounting base is installed above the mounting plate, the reciprocating cylinder is installed on the inner side of the mounting base, and the vibration block is installed at one end of the reciprocating cylinder.

[0009] A further improvement is that the vibration block is parallel to the bottom of the feeding chamber, and a plastic pad is provided on the inner side of the vibration block.

[0010] The beneficial effects of this utility model are as follows: By setting an adjustment mechanism below the mounting plate, the mutual cooperation between the mounting cavity, self-locking motor, driving gear, driven gear, transmission rod, connecting rod, limit rail, and limit block of the adjustment mechanism can flexibly drive the discharge pipe to rotate, quickly adjust the concrete discharge angle, adapt to different receiving equipment positions, reduce equipment movement, avoid material spillage and waste, eliminate the need for machine stoppage for adjustment, improve production continuity and efficiency, and reduce labor intensity; By setting a vibration mechanism above the mounting plate, the mutual cooperation between the mounting seat, reciprocating cylinder, and vibration block of the vibration mechanism can drive the two vibration blocks to move and impact the discharge chamber, making the discharge chamber more effective during discharge, and preventing concrete material from adhering to the inner wall of the discharge chamber, thus saving raw materials and greatly improving the practicality of the mechanism in use.

[0013] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0014] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a discharge mechanism for concrete production, including a discharge chamber 1, a discharge pipe 2 installed below the discharge chamber 1, a discharge pipe 3 installed below the discharge chamber 1, a rotary joint 4 installed at one end of the discharge pipe 3, the discharge pipe 2 and the rotary joint 4 being rotatably connected to each other, a first servo motor 5 installed at one end of the discharge pipe 3, a screw conveyor shaft 6 installed inside the discharge pipe 3, the output end of the first servo motor 5 being connected to one end of the screw conveyor shaft 6, a discharge port 7 being opened on one side of the discharge pipe 3, mounting plates 8 being installed below both sides of the discharge chamber 1, a vibration mechanism being provided above the mounting plates 8, and an adjustment mechanism being provided below the mounting plates 8.

[0015] The adjustment mechanism includes a mounting cavity 9, a self-locking motor 10, a driving gear 11, a driven gear 12, a transmission rod 13, a connecting rod 14, and a limiting structure. The mounting cavity 9 is installed below a mounting plate 8. The self-locking motor 10 is installed on one side of the top of the mounting cavity 9, and the driving gear 11 is installed on one side inside the mounting cavity 9. The output end of the self-locking motor 10 is connected to one end of the driving gear 11. The driven gear 12 meshes with one side of the driving gear 11. The transmission rod 13 is installed on one end of the driven gear 12, and the connecting rod 14 is installed at the bottom end of the transmission rod 13. The bottom end of the connecting rod 14 is connected to the output end of the self-locking motor 10. The top of the material pipe 3 is connected to the self-locking motor 10. When it is necessary to adjust the discharge position of the discharge port 7, the self-locking motor 10 is started to drive the drive gear 11 to rotate, which in turn drives the driven gear 12 to rotate. Therefore, under the limit of the limit rail 15 and the limit block 16, the driven gear 12 drives the transmission rod 13 and the connecting rod 14 to rotate, which in turn drives the discharge pipe 3 to rotate, thereby adjusting the discharge position of the discharge port 7. This allows for flexible rotation of the discharge pipe 3, quick adjustment of the concrete discharge angle, adaptation to different receiving equipment positions, reduced equipment movement, avoidance of material spillage and waste, no need to stop the machine for adjustment, improved production continuity and efficiency, and reduced labor intensity.

[0016] The limiting structure includes a limiting rail 15 and a limiting block 16. The limiting rail 15 is installed on one side of the mounting cavity 9, and the limiting block 16 is provided inside the limiting rail 15. The bottom end of the limiting block 16 is connected to the top end of the transmission rod 13. The limiting rail 15 and the limiting block 16 are mutually adapted to each other and form a sliding structure. The limiting rail 15 has an arc-shaped design, and the center of the limiting rail 15 and the center of the driven gear 12 are on the same straight line. In use, the mutual cooperation between the limiting rail 15 and the limiting block 16 can limit the movement of the transmission rod 13 and the connecting rod 14, making the transmission rod 13 more stable when rotating.

[0017] The vibration mechanism includes a mounting base 17, a reciprocating cylinder 18, and a vibration block 19. The mounting base 17 is installed above the mounting plate 8. The reciprocating cylinder 18 is installed on the inner side of the mounting base 17. The vibration block 19 is installed at one end of the reciprocating cylinder 18. In use, the reciprocating cylinder 18 is activated to drive the vibration block 19 to move. The vibration block 19 vibrates the feeding chamber 1, which makes the concrete material feeding efficiency in the feeding chamber 1 higher and the feeding effect of the feeding chamber 1 better. The concrete material is less likely to stick to the inner wall of the feeding chamber 1, saving raw materials and thus greatly improving the practicality of the mechanism in use.

[0018] The vibrating block 19 is parallel to the bottom of the feeding chamber 1. A plastic soft pad is provided on the inner side of the vibrating block 19. The use of the plastic soft pad ensures that the vibrating block 19 will not damage the feeding chamber 1 when it vibrates.

[0019] Working principle: Concrete raw materials enter the discharge chamber 1 through the mixer and are discharged through the discharge pipe 2. At this time, the reciprocating cylinder 18 is started to drive the vibrating block 19 to move, and the vibrating block 19 vibrates the discharge chamber 1, making the discharge efficiency of concrete raw materials in the discharge chamber 1 higher. Then, the first servo motor 5 is started to drive the screw conveyor shaft 6 to rotate, and the screw conveyor shaft 6 is used to transport concrete. The concrete is discharged through the discharge port 7. When it is necessary to adjust the discharge position of the discharge port 7, the self-locking motor 10 is started to drive the drive gear 11 to rotate, which in turn drives the driven gear 12 to rotate. Therefore, under the limit of the limit rail 15 and the limit block 16, the driven gear 12 drives the transmission rod 13 and the connecting rod 14 to rotate, which in turn drives the discharge pipe 3 to rotate, thereby adjusting the discharge position of the discharge port 7.
