Description

Technical Field

[0001] This utility model relates to the technical field of concrete aggregate recycling, and in particular to a concrete aggregate separation device. Background Technology

[0002] Concrete is commonly used as the main material for buildings during construction. Due to its excellent compressive strength and durability, concrete is widely used in various construction scenarios.

[0003] During construction, it is inevitable that the amount of concrete mixed will exceed the amount actually used. If the excess concrete is discarded, it will not only waste materials and costs, but also pollute the surrounding environment.

[0004] Therefore, it is necessary to recycle the sand and gravel in this part of the concrete for future use. The common recycling method is to use a sedimentation tank for sedimentation, but this method takes a long time and is not very practical. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present invention provides a concrete sand and gravel separation device.

[0006] The present invention provides a concrete sand and gravel separation device with the following technical solution:

[0007] A concrete sand and gravel separation device includes a main box with an open top. A support frame is laterally slidable inside the main box, and a separation box is detachably installed on the support frame. A lateral drive mechanism for driving the support frame to reciprocate is provided on the main box. A guide plate is inclinedly provided inside the main box and is located below the separation box. A sand storage box is provided at the bottom of the main box and is located below the bottom edge of the guide plate. A lifting mechanism for lifting the sand storage box is also provided on the main box.

[0008] By adopting the above technical solution, the horizontal drive mechanism drives the support frame to move the separation box back and forth, so as to separate the gravel and sand. The sand first falls onto the guide plate, and then falls from the guide plate into the sand storage box. The sand storage box is lifted by the lifting mechanism. The separation box and the sand storage box can be lifted out and the gravel and sand can be dumped respectively. The use of this sand and gravel separation device significantly improves the separation efficiency of gravel and sand, and at the same time facilitates the separate removal of gravel and sand. It is simple and quick for the staff to operate.

[0009] Optionally, the support frame includes longitudinally arranged vertical bars and horizontal bars fixed between the vertical bars.

[0010] By adopting the above technical solution, the support frame is simple in composition and easy to assemble the separation box on the longitudinal and transverse bars.

[0011] Optionally, the lateral drive mechanism includes a bracket seat set on the inner wall of the main housing, a receiving box installed on the bracket seat, a baffle slidably installed inside the receiving box, a longitudinal rod slidably passing through the receiving box and fixedly connected to the baffle, a compression spring installed inside the receiving box located on one side of the main housing, the compression spring elastically supporting the baffle and the inner wall of the receiving box, a rotating shaft rotatably connected inside the receiving box located on the other side of the main housing, a cam mounted on the rotating shaft that abuts against the baffle, a drive motor connected to the end of the rotating shaft, and the drive motor mounted on the main housing.

[0012] By adopting the above technical solution, the drive motor drives the cam to rotate, and the cam, in conjunction with the compression spring, realizes the reciprocating movement of the support frame. This transverse drive mechanism is simple to operate and highly efficient.

[0013] Optionally, the bracket includes a horizontally fixed tray, with the receiving box fixed to the top surface of the tray.

[0014] Optionally, a mounting plate is vertically fixed to one side of the pallet. The mounting plate is fitted against the inner wall of the main box and is connected to the main box by bolts. A diagonal brace is fixed between the bottom surface of the pallet and the mounting plate.

[0015] By adopting the above technical solution, the bolt pair facilitates the installation or disassembly of the bracket seat.

[0016] Optionally, a pulley block is installed on the longitudinal bar, and the pulley block provides rolling support to the top surface of the support plate.

[0017] By adopting the above technical solution, the pulley system makes the support frame move more smoothly and provides vertical support for the support frame.

[0018] Optionally, the lifting mechanism includes a second drive motor mounted on the main housing, a winding wheel mounted on the output shaft of the second drive motor, a rope for lifting the sand storage box wound on the winding wheel, a steering wheel mounted on the top of the main housing, and the rope going up past the steering wheel and then down into the main housing.

[0019] By adopting the above technical solution, the second drive motor drives the winding wheel to rotate, which in turn drives the rope to pull the sand storage box to lift. This lifting mechanism is simple to operate and highly efficient.

[0020] Optionally, a positioning rod is vertically fixed to the bottom plate of the main box, and a sliding sleeve is fixed to the outer wall of the sand storage box, with the sliding sleeve slidingly fitted onto the positioning rod.

[0021] By adopting the above technical solution, the positioning rod and the sliding sleeve cooperate to accurately place the sand storage box into the main box, so as to receive sand particles and lift it out next time. Attached Figure Description

The mounting plate 401 is set against the inner wall of the main housing 1 and is installed on the side wall of the main housing 1 by bolt pair 402. A diagonal brace 403 is also fixed between the bottom surface of the support plate 400 and the mounting plate 401.

[0031] Reference Figure 1 , Figure 3 and Figure 4 A receiving box 41 is fixedly connected to the top surface of the pallet 400. A baffle 42 is provided inside the receiving box 41. The longitudinal rod 20 slides through the receiving box 41 and is fixedly connected to the baffle 42. A compression spring 43 is provided inside the receiving box 41 located on one side of the main box 1. The compression spring 43 is elastically supported between the inner wall of the receiving box 41 and the baffle 42. A rotating shaft 44 is rotatably connected inside the receiving box 41 located on the other side of the main box 1. A cam 45 is installed on the rotating shaft 44. The cam 45 contacts the baffle 42. The rotating shaft 44 passes through the two cams 45 and is connected to the output shaft of the drive motor 46 installed on the outer wall of the main box 1. That is, the two cams 45 are driven to rotate synchronously by the drive motor 46.

[0032] Reference Figures 1-4 A pulley block 47 is also installed on the longitudinal rod 20. The pulley block 47 is slidably set on the top surface of the support plate 400. The pulley block 47 makes the support frame 2 move more smoothly and provides vertical support for the support frame 2. A guide plate 5 is fixedly inclined inside the main box 1. The guide plate 5 is located below the support frame 2 and is used to receive and guide the sand particles to move downward. A sand storage box 6 is placed inside the main box 1.

[0034] The implementation principle of this utility model embodiment is as follows: Water is injected into the main box 1, and concrete is placed into the separation box 3. The drive motor 46 is started, and the drive motor 46 drives the cam 45 to move the longitudinal rod 20. The compression spring 43 cooperates to drive the longitudinal rod 20 to move in the opposite direction. Under this cyclical cooperation, the separation box 3 moves back and forth to screen, and the gravel in the concrete remains in the separation box 3. After separation, the separation box 3 is lifted out and the gravel is dumped using hoisting machinery. The sand first falls onto the guide plate 5, and then falls into the sand storage box 6. The drive motor 70 in the lifting mechanism 7 drives the pull rope 72 to lift the sand storage box 6. Then, other hoisting machinery is used to lift the sand storage box 6 out and dump the sand. The positioning rod 75 cooperates with the sliding sleeve 76 to make the sand storage box 6 accurately placed into the main box 1 to receive the sand and lift it out next time. The use of this sand and gravel separation device significantly improves the separation efficiency of gravel and sand, and facilitates the separate removal of gravel and sand. It is simple and quick for workers to operate.
