Description

Technical Field

[0001] The utility model belongs to the technical field related to construction waste treatment, and particularly relates to an automatic screening device for construction waste. Background Art

[0002] Construction waste refers to construction waste generated in engineering projects due to human or natural reasons, including waste soil, abandoned soil, silt and abandoned materials. With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the construction waste generated is increasing day by day. These materials are of no help to the building itself, but they are substances generated in the process of construction and need to be processed accordingly, so corresponding screening devices are needed.

[0003] However, the existing construction waste screening device does not have the function of pushing the construction waste when in use, so the construction waste is easily accumulated in the internal position of the screening device, which makes the interior of the screening device easy to be blocked. At the same time, the existing screening device does not have the function of fluctuation when in use, so the dust in the gap of the construction waste cannot be detached from the surface, so it is impossible to effectively screen the construction waste comprehensively. To this end, we provide an automatic screening device for construction waste to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-6 The utility model is an automatic screening device for construction waste; the construction waste is pushed by pushing the bar 6 at the inner side of the semicircular screen plate 1 to avoid excessive accumulation of construction waste on the inner side of the semicircular screen plate 1. At the same time, the spring 503 pushes the semicircular screen plate 1 to reset it, so that the construction waste fluctuates up and down, which is convenient for quickly screening the dust trapped in the construction waste and realizing comprehensive screening of the dust.

[0030] Specifically; a semicircular sieve plate 1 and a bottom plate 3 located directly below the semicircular sieve plate 1, characterized in that: a dust box 4 is provided on the upper end surface of the bottom plate 3 and is located directly below the semicircular sieve plate 1, a pushing bar 6 is provided on the inner side of the semicircular sieve plate 1, mounting bars 102 are fixed to the upper end surfaces on the left and right sides of the semicircular sieve plate 1, a lead screw 2 is provided above the mounting bar 102 located on the left side of the dust box 4, a motor 201 is provided at the front end of the lead screw 2 and is transmission-connected thereto, a vibration cylinder 5 is fixed to the upper surface of the bottom plate 3 at the front and rear ends of the mounting bar 102, a support rod 501 connected to the lower end surface of the mounting bar 102 by bolts is provided directly above the vibration cylinder 5, a round block 502 is fixed to the lower end surface of the support rod 501, and a spring 503 is fixed to the lower end surface of the round block 502.

[0031] The operation process of this embodiment is as follows: through the use of the above-mentioned structure, when it is necessary to screen the construction waste, the construction waste can be dumped at the position of the semicircular screen plate 1, and then the motor 201 is controlled to work, so that the motor 201 will directly drive the lead screw 2 to rotate, so that the lead screw 2 will drive the push bar 6 to slide along the inner position of the semicircular screen plate 1, and at this time, the push bar 6 will drive the construction waste to move at the inner position of the semicircular screen plate 1, and then the construction waste will be pushed in the left and right directions inside the semicircular screen plate 1, so that the construction waste will not be over-accumulated, so that the dust in the construction waste can be removed from the semicircular screen plate 1. The circular sieve plate 1 is screened at the circumferential side to make the dust slide into the dust collecting box 4. At the same time, when the construction waste is poured into the inner side of the semicircular sieve plate 1, the construction waste will impact the semicircular sieve plate 1, causing the semicircular sieve plate 1 to vibrate up and down. As a result, the semicircular sieve plate 1 will drive the round block 502 to slide along the vibration cylinder 5 through the support rod 501, and the round block 502 will compress the spring 503. Therefore, the semicircular sieve plate 1 is pushed and reset by the spring 503, so that the construction waste fluctuates up and down on the inner side of the semicircular sieve plate 1, thereby facilitating the rapid screening of the dust trapped in the construction waste. Specific embodiment 2

[0033] See also Figure 2 , 3 On the basis of the first specific embodiment, the positioning plate 601 is limited by the positioning rod 104 to ensure the stable sliding of the pushing bar 6.

[0035] The operation process of this embodiment is: when the pushing bar 6 slides inside the semicircular screen plate 1, the pushing bar 6 will drive the positioning plate 601 to slide on the mounting bar 102, and the positioning plate 601 will slide on the peripheral position of the positioning rod 104 through the positioning hole 604, so the positioning rod 104 limits the positioning plate 601 to ensure that the pushing bar 6 can slide stably, and at the same time, the pushing bar 6 will drive the scraper 602 to quickly push the construction waste on the semicircular screen plate 1. Specific embodiment three

[0037] See also Figure 4 , 6 On the basis of the first specific embodiment, the strip block 401 is located inside the strip opening 301 to limit the position of the dust collecting box 4, thereby ensuring that the dust collecting box 4 stably receives the dust.
