Description

Technical Field

[0001] The utility model relates to the technical field of construction waste aggregate processing, in particular to a novel device for efficiently crushing construction waste aggregate. Background Art

[0002] Construction waste aggregate refers to waste materials generated during construction or demolition, usually fragments or residues of building materials such as concrete, bricks, tiles, and stones. These waste aggregates usually contain raw materials such as cement, sand, and gravel. After construction or demolition, the unused or damaged parts become waste aggregates. When crushing construction waste, a large amount of dust particles are easily generated and scattered, which can easily have an adverse effect on the health of workers.

[0003] After searching, a Chinese patent with announcement number CN211989081U discloses a construction waste crushing device. The utility model can avoid the flying of dust particles during crushing and discharging by setting structures such as a water inlet pipe, branch pipe one, branch pipe two, nozzle, baffle and spring, thereby ensuring the health of the staff; by setting structures such as a crushing roller, a rotating shaft, a rolling roller, a motor, a bevel gear one, a bevel gear two, a gear one and a gear two, the construction waste is first crushed and then rolled, with a good crushing effect and easy recycling.

[0004] When the above crushing device is in use, the three crushing rollers crush the fallen construction waste aggregates, and the two rolling rollers rotate synchronously in opposite directions to roll the fallen construction waste aggregates. However, it is inconvenient to screen the crushed aggregates, and the different particle sizes of the aggregates will affect the uniformity of the concrete, resulting in poor use effect.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A novel device for efficiently crushing construction waste aggregates comprises a storage box, two first motors are fixedly installed on the rear side of the storage box, the output shaft ends of the two first motors are fixedly connected to crushing rollers, and the front and rear ends of the two crushing rollers are movably connected to the inside of the storage box through bearings, a feed hopper is fixedly connected at the top center position of the storage box, a filter inclined plate is movably arranged inside the storage box, the front and rear sides of the two filter inclined plates are fixedly connected to guide plates, a connecting assembly is provided between the two guide plates and the storage box, one side of the storage box is fixedly connected to a side frame, the top of one side of the side frame is fixedly connected to an inclined pipe, and one end of the inclined pipe is fixedly connected to the feed hopper, a transport assembly is provided on the side frame, and the transport assembly comprises a second motor, a rotating shaft and a screw rod.

[0011] Furthermore, sliding rods are movably provided on both the front and rear sides of the reciprocating screw rod, and one end of the two sliding rods passes through the slider and is fixedly connected to the material storage box.

[0012] It can be seen that in the above technical solution, the two slide bars limit the rotation of the slider.

[0013] Furthermore, the two connecting assemblies each include two telescopic rods and two springs, the four telescopic rods are respectively located inside the four springs, the top ends of the four springs are respectively fixedly connected to the two material guide plates, and the bottom ends of the four springs are fixedly connected to the material storage box.

[0016] It can be seen that in the above technical solution, before crushing, the cover plate is closed on the feed hopper to prevent dust from splashing.

[0017] Furthermore, a transparent plate is fixedly mounted on the rear side of the storage box.

[0018] It can be seen that in the above technical solution, a transparent plate is used to facilitate observation of the crushing of construction waste aggregates.

[0019] The utility model has the following advantages:

[0020] 1. The utility model crushes construction waste aggregates through two crushing rollers, and two guide plates guide the aggregate particles and make them fall on the filter inclined plate. The filter inclined plate screens the aggregate particles, and qualified aggregate particles pass through the filter inclined plate, and unqualified aggregate particles are introduced into the side frame by the filter inclined plate.

[0021] 2. The utility model can drive the first bevel gear to rotate through the rotating shaft, thereby driving the second bevel gear to rotate, and then driving the reciprocating screw to rotate. The reciprocating screw can drive the slider to move back and forth left and right, thereby driving the top block to move back and forth left and right. When the top block moves to the right, the top block will lift the filter inclined plate, thereby driving the four springs to stretch. When the top block moves to the left, the four springs rebound and drive the two guide plates to move downward, thereby driving the filter inclined plate to move downward. This cycle is repeated to screen the aggregate particles and prevent the aggregate particles from clogging the filter inclined plate. The operation is simple and easy to use.

[0033] Furthermore, the second motor 801 is fixedly installed on the storage box 1, the bottom end of the rotating shaft 802 is fixedly connected to the end of the output shaft of the second motor 801, and the top end of the rotating shaft 802 is fixedly connected to the screw rod 803, and the top and bottom ends of the screw rod 803 are movably connected to the side frame 5 through bearings.

[0034] Furthermore, a first bevel gear 804 is fixedly sleeved on the rotating shaft 802, and a moving assembly 12 is provided on one side of the first bevel gear 804. The moving assembly 12 includes a second bevel gear 1201, a reciprocating screw rod 1202, a slider 1203 and a top block 1205, and the second bevel gear 1201 is meshed with the first bevel gear 804, both ends of the reciprocating screw rod 1202 are movably connected to the storage box 1 through bearings, the slider 1203 is threadedly connected to the reciprocating screw rod 1202, and the bottom end of the top block 1205 is connected to the slider 12 03 is fixedly connected, and the top of the top block 1205 is in contact with the filter inclined plate 11, the front and rear sides of the reciprocating screw rod 1202 are movably provided with sliding rods 1204, and one end of the two sliding rods 1204 passes through the slider 1203 and is fixedly connected to the storage box 1, the two connecting components include two telescopic rods 6 and two springs 7, the four telescopic rods 6 are respectively located inside the four springs 7, the top ends of the four springs 7 are respectively fixedly connected to the two guide plates 13, and the bottom ends of the four springs 7 are fixedly connected to the storage box 1.
