Description

Technical Field

[0001] The utility model relates to the field of sand and gravel separation, in particular to a sand and gravel separation device for processing concrete waste. Background Art

[0002] Sand and gravel refer to a loose mixture of sand and crushed stone. In geology, mineral or rock particles with a particle size of 0.074 to 2 mm are called sand, and particles larger than 2 mm are called gravel or angular gravel (the difference between the two lies in the degree of roundness).

[0003] During the construction process at a construction site, the demolished concrete needs to be processed, and then the crushed concrete is screened through a sand and gravel separation device to separate the sand from the gravel, so that it can be recycled and reused, saving production costs.

[0004] Existing sand and gravel separation devices usually place concrete waste into the separation device, and separate the sand and gravel through feeding equipment and screen plates during the falling process. However, during the falling transportation process, the overall speed is too fast, which leads to incomplete screening effect. A few sand particles may not be affected by the screening under fast movement, and the screening effect is not thorough. When the crushed stone is discharged, a small amount of sand and gravel are still discharged with it. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a concrete waste processing sand and gravel separation device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete waste processing sand and gravel separation device, comprising a machine body, a motor box is fixedly installed on one side of the machine body, and a transmission rod is movably installed on one side of the motor box, rotating rods are movably installed on both sides of the machine body, and a half gear is fixedly installed on one side of the rotating rod, a baffle is movably installed in the middle of the machine body, and connecting blocks are fixedly installed on both sides of the baffle, racks are fixedly installed on both sides of the connecting block, and the racks and the half gears are meshingly connected, a screw rod is provided on one side of the rotating rod, and a movable plate is movably installed in the middle of the screw rod, and the rotating rod and the screw rod are connected by a chain.

[0007] By adopting the above technical solution, by setting the baffle and the half gear, the raw material is preliminarily screened when it falls on the surface of the screen plate. When the baffle is lowered, the falling of the material can be stagnant, and the falling speed of the material can be slowed down, so that the sand can have enough time to fall. When the baffle rises, the material falls to the plane at one end of the screen plate, so that through the push of the movable plate, while pushing the stone particles, the remaining sand particles can be further screened and fall above the inclined plate. At this time, the separation of sand and gravel is more thorough.

[0008] The utility model is further configured as follows: a sieve plate is fixedly installed inside the machine body, and one end of the sieve plate is set as an inclined surface, the movable plate is fitted with the other end of the sieve plate, the screw rod and the transmission rod are meshed and connected, and second discharge ports are opened on both sides of the machine body, and the second discharge ports are matched with the movable plate.

[0009] By adopting the above technical solution and setting the movable plate and the sieve plate, the movable plate can cooperate with the sieve plate during movement. At the same time, the sieve plate limits the movable plate, ensuring that the movable plate will not deviate during movement, thereby improving the overall working stability.

[0010] The utility model is further configured that unloading plates are fixedly installed on both sides of the machine body, and the unloading plates are matched with the second discharge port, and a collection box is installed at one end of the machine body, and the collection box is communicated with the unloading plates.

[0011] By adopting the above technical solution, by setting up a collecting box and a discharge plate, the discharged stones can be discharged into the collecting box through the discharge plate, and the screened stones can be collected and processed, which is more conducive to improving the overall work efficiency.

[0012] The utility model is further configured as follows: a limit plate is fixedly installed in the middle of the transmission rod, and a movable block is movably installed inside the limit plate, a spring is installed at one end of the movable block, and the movable block is connected to the transmission rod through the spring, an arc surface is set at one end of the movable block, and the movable block matches the screen plate.

[0013] By adopting the above technical solution and setting a limit plate and a movable block, when the transmission rod rotates, the movable block can vibrate the screen plate to speed up the screening work. By setting the limit plate, the movement of the movable block can be limited to ensure that the position of the movable block will not be offset.

[0014] The utility model is further configured that an inclined plate is fixedly installed at the bottom end of the machine body, and a first discharge port is opened at one side of the machine body, the inclined plate cooperates with the first discharge port, and a plurality of groups of holes are opened on the surface of the screen plate.

[0015] By adopting the above technical solution, by setting the inclined plate, the sand can slide on the surface of the inclined plate and be discharged through the first discharge port. The placement positions of the sand and stones are separated, and the separation can be carried out normally.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] The utility model provides a baffle and a half gear so that the raw materials are preliminarily screened when they fall onto the surface of the screen plate. When the baffle is lowered, the falling of the materials is stagnant and the falling speed of the materials is slowed down, so that the sand particles have enough time to fall. When the baffle is raised, the materials fall onto the plane at one end of the screen plate, so that the remaining sand particles are further screened while the stone particles are pushed by the movable plate, so that the sand particles fall onto the upper part of the inclined plate. At this time, the separation of the sand and the gravel is more thorough. By providing the movable block, when the sand and the gravel are blocked by the baffle, the movable block continuously collides with the screen plate under the rotation of the transmission rod, so that the sand particles fall onto the surface of the inclined plate, which is more conducive to the separation of the sand and the gravel and avoids the problem that a small number of sand particles adhere to the surface of the stone and are difficult to separate.

When the half gear 8 rotates, the half teeth contact the rack 9 on one side, causing the rack 9 to rise. When the rack 9 rises to a certain position, the half teeth on the outer side of the half gear 8 gradually contact the rack 9 on the other side, causing the rack 9 to begin to descend after the ascent. When the rack 9 moves, it can drive the baffle 11 to move. At this time, the baffle 11 realizes up and down displacement. During the rising process of the baffle 11, the raw material loses its cover and moves to the plane of the screen plate 6, thereby moving the movable plate 5 to move the stone to the second discharge port 16.
