Description

Technical Field

[0001] The utility model relates to the technical field of construction waste crushers, in particular to a construction waste crusher that is easy to move. Background Art

[0002] The mobile construction waste crusher is an improvement over traditional fixed crushers. Traditional crushers are fixed in one location, requiring construction waste to be transported there, crushed by crushing rollers, and then transported away by conveyor equipment. This mobile crusher, however, can be deployed directly to the construction waste disposal site, eliminating the need for long-distance material transportation. Its integrated crushing and conveying functions allow for flexible relocation to accommodate diverse sites, simplifying the processing process, reducing transportation costs and time, and improving the efficiency of construction waste crushing, sorting, and secondary utilization. It is therefore more suitable for the processing needs of dispersed and diverse construction waste sites.

[0003] However, existing mobile crushers still have defects: the conveyor belt has a fixed angle, which is difficult to adapt to the height and position of the ground and different unloading targets, often causing materials to fall, accumulate and clog, affecting efficiency or even shutting down. At the same time, there is no shielding device when the crushed material falls to the conveyor belt, and the material is easy to splash and scatter, increasing the workload of cleaning, posing a safety hazard, and also aggravating air pollution, reducing the utilization rate of material collection, and violating the concept of efficient and environmentally friendly secondary utilization, which urgently needs to be improved. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a mobile construction waste crusher with the advantages of flexible adjustment of the conveyor belt angle to adapt to different unloading scenarios and a shielding device to prevent material splashing. It solves the problems in the background technology that the fixed conveyor belt angle is difficult to adapt to the height and position of the ground and different unloading targets, resulting in material falling, accumulation and blockage, and affected efficiency, and the lack of a shielding device causes material splashing and scattering, increases the cleaning workload, poses a safety hazard, aggravates air pollution, and reduces the utilization rate of material collection.

[0005] In order to achieve the purpose of flexibly adjusting the angle of the above-mentioned conveyor belt to adapt to different unloading scenarios and providing a shielding device to prevent material from splashing, the utility model provides the following technical solutions: a construction waste crusher that is easy to move, including a truck, mounting frames are installed on four sides of the middle of the truck compartment, the top of the mounting frame is fixedly connected with a placement plate, and the top of the placement plate is installed with a crusher group, two connecting frames are fixedly connected to the middle of one side of the truck compartment, and one side of the connecting frame is located at the bottom of the placement plate, and the two connecting frames are fixedly connected to a connecting plate 1 on one side of the bottom of the placement plate, and two groups of mounting blocks are installed on both sides of the connecting plate 1, and each group of mounting blocks is divided into two, a rotating rod is rotatably connected between the mounting blocks of one group, and the outer walls of the two groups of rotating rods located between the mounting blocks are fixedly connected to the conveyor belt mounting plates, and a conveyor belt is installed between the two conveyor belt mounting plates;

[0006] The two ends of the support frame are connected with the support of the U-shaped support plate, and the two ends of the support frame are connected with the support of the U-shaped support plate.

[0007] As a further solution of the present invention: a material discharge chute is opened in the middle of the top of the placement plate, and the material discharge chute is matched with the crushing unit.

[0008] As a further solution of the present invention: both sides of the bottom of the placement plate are fixedly connected with a material blocking plate 1, and both sides of the bottom of the two material blocking plates 1 are fixedly connected with an elastic belt.

[0009] As a further solution of the present invention: the two elastic belts are fixedly connected to a mounting plate on one side away from the material blocking plate, and the two mounting plates are fixedly connected to the two conveyor belt mounting plates.

[0010] As a further solution of the present invention: a side of the bottom of the placement plate away from the baffle plate one is fixedly connected to the baffle plate two, and both sides of the baffle plate two are fixedly connected to the baffle plate one.

[0011] As a further solution of the present invention: one side of the second baffle plate is rotatably connected to a resistance plate, and the resistance plate is in resistance with one side of the conveyor belt.

[0012] As a further solution of the present invention: the side of the resistance plate away from the conveyor belt is fixedly connected with evenly distributed springs, and the springs are fixedly connected to the second baffle plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this utility model, when the conveyor belt angle needs to be adjusted, the brake motor is activated, driving the screw to rotate, causing the U-shaped push plate, threadedly connected to the screw, to slide back and forth within the chute. The sliding of the U-shaped push plate causes the fixed rod to tilt. The backward tilt of the fixed rod pulls the connecting push plate downward. The connecting push plate, through the connecting rod, drives the conveyor belt mounting plate and conveyor belt to move synchronously. As the conveyor belt moves downward, it rotates around the rotating rod as a base point to achieve angle adjustment. This allows precise adaptation to the height and position of different unloading targets, effectively preventing material from falling or clogging, ensuring a smooth and efficient conveying process and improving overall operational efficiency.

[0015] 2. In the present invention, when the conveyor belt adjusts its angle, it will drive the mounting plate to move. The movement of the mounting plate stretches the elastic belt connected to the baffle plate 1. The elastic belt cooperates with the baffle plate 1 to effectively block the falling material and prevent the material from splashing and scattering. The baffle plate 2 further blocks the material. The resistance plate rotatably connected on one side always contacts the feeding end of the conveyor belt under the action of the spring force, preventing the material from falling from the gap, reducing the cleaning workload, eliminating safety hazards, and improving the material collection and utilization rate, which is in line with the concept of environmental protection.
