Description

Technical Field

[0001] This utility model belongs to the field of construction waste treatment technology, specifically relating to a waste concrete crusher. Background Technology

[0002] In the treatment of waste concrete, concrete can be recycled by crushing it into aggregate. However, in existing crushing devices, a large amount of concrete is poured onto the crushing roller, which puts a lot of pressure on the crushing roller and affects the crushing effect. In addition, some concrete particles are too large after a single crushing and need to be crushed again after screening, which affects the crushing efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a waste concrete crusher to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this waste concrete crusher to solve its technical problems is as follows: A waste concrete crusher is provided, including a housing. The housing contains two cooperating crushing rollers, which are rotatably mounted on corresponding supports. The supports are fixedly mounted in the housing, and pressure sensors are fixedly mounted on the supports. A first motor for driving the two crushing rollers to rotate is fixedly mounted on the housing. A feed inlet is opened at the top of the housing and a feed pipe is fixedly mounted thereon. A first through groove is opened on one side of the feed pipe, and an inclined plate is provided in the first through groove. An electric telescopic rod is fixedly mounted on one side of the feed pipe, and the movable end of the electric telescopic rod is fixedly connected to the inclined plate. A discharge outlet is opened at the bottom of the housing.

[0005] Furthermore, a second through groove and a third through groove are respectively opened on both sides of the box body. A screening roller passing through the second through groove and the third through groove is installed on the box body. The screening roller is provided with screen holes. A gear ring is coaxially fixedly installed on one side of the screening roller. The other side of the screening roller is rotatably installed on the second through groove and the third through groove through a bearing. A second motor is fixedly installed on the box body below the second through groove. A gear is fixedly installed at the output end of the second motor. The gear meshes with the gear ring. Several baffles are fixedly installed on the screening roller.

[0006] Furthermore, a collection hopper connected to the feed inlet is fixedly installed on the box body.

[0007] Furthermore, the guide plate is fixedly installed on the third through groove.

[0008] Furthermore, a controller is fixedly installed on the housing, and the controller is connected to the pressure sensor and the electric telescopic rod via a circuit.

[0009] Furthermore, support legs are fixedly installed at the bottom of the box.

[0010] Furthermore, a conveyor belt is provided below the box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides an example of a waste concrete crusher. When in use, the first motor is started to drive the crushing roller to rotate. By collecting data from the pressure sensor, when the amount of concrete on the crushing roller decreases, the pressure sensor reading decreases. The electric telescopic rod is then controlled to push the inclined plate to move, opening the feed pipe so that material can be fed above the crushing roller. After feeding, the crushing roller applies more force to both sides when crushing concrete, and the pressure sensor reading increases. The electric telescopic rod is then controlled to retract, driving the inclined plate to close the feed pipe, thus pausing feeding and preventing excessive concrete accumulation that could affect the crushing roller's crushing function. This device allows for convenient feeding based on the amount of concrete.

[0012] 2. In the present invention, a waste concrete crusher is used such that a second motor drives a gear to rotate, which in turn drives a gear ring and a screening drum to rotate. The fully crushed material falls from the screening drum and is discharged from the discharge port. Larger pieces of material are lifted to the top of the box as the screening drum and baffle rotate, and then re-enter the feed port for crushing.

[0013] 3. The waste concrete crusher of this utility model can be conveniently fed into the feed inlet through the collection bucket, and can also collect the crushed material lifted up by the baffle. 4. The waste concrete crusher of this utility model can conveniently guide the crushed material falling from the screening drum through the guide plate.

[0014] 5. In a waste concrete crusher according to this utility model, a pressure sensor can detect pressure. When the pressure sensor reading decreases, the controller receives a signal feedback from the pressure sensor and controls the electric telescopic rod to push the inclined plate to move, opening the feed pipe so that material can be fed above the crushing roller. When the crushing roller is crushing concrete, the force applied to both sides increases, the pressure sensor reading increases, the controller receives a signal feedback from the pressure sensor, controls the electric telescopic rod to retract and drive the inclined plate to close the feed pipe, thus stopping the feeding.

[0015] 6. The waste concrete crusher of this utility model can be easily supported and raised by the support legs.

[0016] 7. The waste concrete crusher of this utility model can conveniently convey crushed aggregates via a conveyor belt. Attached Figure Description

[0021] Example 1: like Figure 1 As shown, this embodiment provides a waste concrete crusher, including a housing 1. The housing 1 is provided with two cooperating crushing rollers 2. The crushing rollers 2 are rotatably mounted on corresponding supports 3. The supports 3 are fixedly mounted inside the housing 1. Pressure sensors 4 are fixedly mounted on the supports 3. A first motor for driving the two crushing rollers 2 to rotate is fixedly mounted on the housing 1. A feed inlet 5 is opened at the top of the housing 1 and a feed pipe 6 is fixedly installed thereon. A first through groove 7 is opened on one side of the feed pipe 6. An inclined plate 8 is provided in the first through groove 7. An electric telescopic rod 9 is fixedly installed on one side of the feed pipe 6. The movable end of the electric telescopic rod 9 is fixedly connected to the inclined plate 8. A discharge port 10 is opened at the bottom of the housing 1.

[0022] In this embodiment, a second through groove 11 and a third through groove 12 are respectively opened on both sides of the box body 1. A screening roller 13 passing through the second through groove 11 and the third through groove 12 is installed on the box body 1. The screening roller 13 is provided with screen holes. A gear ring 14 is coaxially fixedly installed on one side of the screening roller 13. The other side of the screening roller 13 is rotatably installed on the second through groove 11 and the third through groove 12 through a bearing. A second motor 15 is fixedly installed on the box body 1 below the second through groove 11. A gear 16 is fixedly installed at the output end of the second motor 15. The gear 16 meshes with the gear ring 14. Several baffles 17 are fixedly installed on the screening roller 13.

When the amount of concrete on the crushing roller 2 decreases, the pressure on the pressure sensor 4 decreases, controlling the electric telescopic rod 9 to push the inclined plate 8 to move, opening the feed pipe 6, allowing material to be fed above the crushing roller 2. After feeding, the crushing roller 2 applies greater force to both sides when crushing concrete, and the reading of the pressure sensor 4 increases. The controller 20 receives the signal feedback from the pressure sensor 4 and controls ... move the inclined plate 8 to move the inclined plate 8. The retraction rod 9 retracts, causing the inclined plate 8 to close the feed pipe 6, thus pausing the feeding and preventing excessive concrete accumulation, which would affect the crushing of the crushing roller 2.
