Description

A construction waste shredder with screening structure

technical field

The utility model belongs to the technical field of construction waste treatment, in particular to a construction waste shredder with a screening structure.

Background technique

Construction waste refers to the general designation of muck, waste concrete, waste masonry and other waste generated in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries.

Some construction waste generated in construction projects is often large in size, and it is difficult to be crushed thoroughly at one time. However, the current garbage shredders often only crush construction waste once, and do not screen the crushed waste; part of the crushed construction waste is still relatively large, resulting in low space utilization during storage and transportation, which not only increases The cost of storage and transportation is increased, and the cost of subsequent processing is also increased.

Utility model content

The utility model provides a construction waste crusher with a sieving structure to solve the problem that the existing construction waste crusher cannot completely crush the construction waste.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a construction waste shredder with a screening structure, including a support seat, the support seat is in the shape of an I-shaped overall, and the upper and lower layers of the support seat It is a support plate, a plurality of support columns are connected between the two support plates, a crushing box is installed on the support plate, the top of the crushing box is designed with an opening, and a screen is installed at the bottom of the crushing box. A crushing mechanism is installed on the crushing box, and the crushing mechanism is used for crushing construction waste.

The principle and effect of the technology: When the crushing mechanism in the crushing box is crushing the construction waste, the crushed fine waste will fall down with the screen, and the construction waste with a larger diameter will remain in the crushing box until it is crushed. The crushing mechanism is completely crushed.

Further, the crushing mechanism includes a rotating shaft, a crushing knife, a driving motor and a transmission belt, the rotating shaft is installed in the crushing box and one end of the rotating shaft passes through the crushing box, the crushing knife is installed on the rotating shaft, and the driving motor is installed On the support plate and outside the crushing box, the transmission belt is sheathed between the output shaft and the rotating shaft of the drive motor.

Adopting the above scheme, the driving motor drives the rotating shaft to rotate, and when the rotating shaft rotates, the pulverizing knife is driven to pulverize the construction waste in the pulverizing box.

Further, the rotating shaft is fixedly connected with a pulley located outside the crushing box, the output shaft of the driving motor is also equipped with a pulley, and the two ends of the transmission belt are sleeved outside the two pulleys.

By adopting the above solution, the transmission belt can be made to run more stably in rotation.

Further, an opening is provided on the supporting plate above the supporting column, the crushing box passes through the opening, and a container is installed at the bottom of the crushing box, and the container is slidably connected to the supporting plate below the supporting column.

With the above solution, the staff can quickly take out the nearly full container and then replace it.

Further, the drive motor is bolted to the support plate.

Adoption of the above scheme facilitates the removal and replacement of drive motors of different types by the staff.

Compared with the prior art, the utility model has the beneficial effect that construction waste with different diameters can be decomposed into pulverized particles with the same diameter, thereby improving the space utilization rate during storage and transportation, and saving storage and transportation costs .

Description of drawings

Fig. 1 is a structural representation of a construction waste pulverizer with a sieving structure of the utility model;

In the figure: 1. support plate; 2. support column; 3. crushing box; 4. driving motor; 5. rotating shaft; 6. crushing knife; 7. pulley; 8. transmission belt.

Detailed ways

Further detailed description will be given below through specific embodiments.

Embodiment: As shown in Figure 1, a construction waste shredder with a sieving structure includes a support seat, and the support seat is in the shape of an I-shape as a whole. The upper and lower layers of the support seat are rectangular support plates 1, and the middle bolts of the two support plates 1 are connected with multiple support columns 2 arranged at intervals. There is an opening in the middle of the support plate 1 above the support column 2, and a crushing box 3 is plugged into the opening. The upper and lower ends of the crushing box 3 are designed with openings. Filter out construction waste particles with consistent diameters. A container is installed in the middle of the two support plates 1, and the container is located directly below the crushing box 3 and a slide rail is installed between the container and the support plate 1. The crushing box 3 is provided with a crushing mechanism, the crushing mechanism includes a rotating shaft 5, a crushing knife 6, a drive motor 4 and a transmission belt 8, the rotating shaft 5 rotates and is installed inside the crushing box 3 and is located above the screen, and one end of the rotating shaft 5 passes through the crushing machine. Case 3 is fixedly connected with belt pulley 7 above. The crushing knife 6 is fixedly installed on the rotating shaft 5 , and the drive motor 4 is bolted on the support plate 1 and is opposite to the crushing box 3 . Pulley 7 is installed on the output shaft of drive motor 4 equally, and drive belt 8 is sleeved outside two pulleys 7.

During work, when the construction waste needs to be crushed, only large pieces of construction waste need to be sent into the crushing box 3, and then the drive motor 4 is turned on. When the output shaft of the driving motor 4 rotates, it drives the rotating shaft 5 to rotate together, and when the rotating shaft 5 rotates, it drives the pulverizer 6 to crush the construction waste. Now when the particle diameter of the pulverized material meets the standard of the sieve, it can fall into the container through the sieve, while the larger construction waste remains in the crushing box 3 and is cut by the crushing knife 6 until its diameter meets the standard of the sieve. Mesh standard. Then just take out the container to store and transport the shredded construction waste.

What is described above is only the embodiment of the present utility model, and common knowledge such as known concrete structure and characteristic in the scheme is not described too much at this, it should be pointed out that for those skilled in the art, without departing from the structure of the present utility model Under the premise of the invention, some deformations and improvements can also be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the utility model implementation and the practicability of the patent. The scope of protection required by this application shall be based on the content of the claims, and the specific implementation methods and other records in the specification may be used to interpret the content of the claims.
