[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation of pipelines and equipment supporting them. A large amount of building materials waste will be generated during the construction of buildings, such as waste wood, stones, etc.; these building materials waste are traditionally stacked in the open air or buried in place, which not only occupies a large amount of space but also causes waste of resources.

[0003] In recent years, crushing devices have emerged to process building materials waste, enabling on-site treatment, making it convenient to send the building materials waste to the garbage recycling point or enabling some building materials waste to be reused after on-site treatment to reduce the cost of building materials. However, the crushing devices currently used generally have the following disadvantages when processing building materials waste: 1. Poor applicability, only applicable to a single type of building materials waste, such as only applicable to wood building materials waste or stone building materials waste; 2. Poor dust removal effect and incomplete dust removal of the crushing device; 3. The crushing tool is easily stuck due to the clamping of the building materials waste and the crushing box body, affecting the overall crushing efficiency; 4. When crushing long wood building materials waste, it is often difficult for this type of building materials waste to enter the crushing box body and external force needs to be used to make it enter, resulting in an increase in crushing cost.

[0043] Embodiment 1

[0044] As Figure 1 shown, this embodiment provides a waste treatment device for construction engineering, including a base 10, a crushing box body 20, a first feeding device 30, and a second feeding device 40. Among them, the base 10 is welded by channel steel, which is convenient for moving the waste treatment device while reducing the weight; the first feeding device 30 is used for feeding wood waste, and the second feeding device 40 is used for feeding stone waste. Both the first feeding device 30 and the second feeding device 40 are arranged at the feeding end of the crushing box body. Further, the first feeding device and the second feeding device are located on the same side of the crushing box body 20; it should be noted that when the waste treatment device crushes wood waste, it feeds through the first feeding device 30, and when it crushes stone waste, it feeds through the second feeding device 40, and the two cannot be misaligned. Furthermore, on the one hand, considering the labor-saving factor of feeding wood waste and stone waste, and on the other hand, considering that longer wood waste is likely to fall into the crushing box body 20, the first feeding device 30 and the second feeding device 40 are arranged from top to bottom.

[0045] As Figure 2 shown, both the first feeding device 30 and the second feeding device 40 are installed on the feeding housing 31, and the second feeding device 40 protrudes from the first feeding device 30, which is convenient for feeding stone waste. Specifically, the second feeding device 40 is a belt conveyor, and the belt conveyor is arranged parallel to the base to minimize the space volume of the waste treatment device as much as possible. In specific practice, in order to increase the load-bearing capacity of the belt conveyor, a supporting frame is added under the belt to increase the load-bearing capacity of the belt.

[0046] Further, the output ends of the first feeding device 30 and the second feeding device 40 are separated by a material dividing plate 311, and the material dividing plate 311 is arranged on the feeding housing 31. In this embodiment, since the first feeding device 30 is located above the second feeding device 40, and the first feeding device 30 is used for feeding wood waste, especially when feeding long wood waste, when the wood waste is bitten, the material dividing plate 311 can effectively prevent the wood waste from falling to the end of the second feeding device 40, ensuring that the wood waste falls into the crushing box body.

[0047] As Figure 1 , Figure 3 shown, the first feeding device 30 includes the feeding housing 31, a feeding shaft 32, six feeding tool holders 33, three feeding tools 34, and a chain plate conveyor 35. Among them, the feeding port of the crushing box body 20 is arranged at its upper part, and the feeding housing 31 is installed at the feeding port of the crushing box body 20 and is communicated with the inner cavity of the crushing box body 20. The feeding shaft 32 is rotatably arranged in the feeding housing 31, and the six feeding tool holders 33 are arranged along the outer surface of the feeding shaft 32; preferably, the arrangement method is staggered and at different heights. Specifically, each feeding tool 34 is horizontally spanned on two feeding tool holders 33. Since the two feeding tool holders 33 are staggered and at different heights, the feeding tool 34 is arranged non-parallel and at different heights with the feeding shaft 32, which is convenient for wood waste to automatically enter the crushing box body 20, especially for long wood waste to enter, without the need to push the wood waste into the crushing box body 20 by external force, so that the waste treatment equipment has strong feeding automation when crushing wood waste. In addition, the feeding tool 34 is installed on the feeding tool holder 33 through a fastener, which is convenient for replacing the feeding tool 34 after wear.

[0048] Further, the chain plate conveyor 35 is arranged on the feeding housing 31 and is located in front of the feeding shaft 32. The feeding tool 34 is in clearance fit with the end of the chain plate conveyor 35, and the size of the clearance is preferably such that it can bite the wood waste. Specifically, the chain plate conveyor 35 is arranged with a higher feeding end and a lower discharging end, that is, it is arranged non-parallel to the belt conveyor, which is convenient for feeding wood waste, especially long wood waste; and, the convex plates on the surface of the chain plate conveyor 35 can promote the entry of wood waste into the crushing box body.

[0049] As Figure 4 and Figure 5As shown, an opening and closing cover 21 is provided on the crushing box body 20, and the opening and closing cover 21 is fastened to the crushing box body 20 through a buckle 22. In a specific implementation, by opening the opening and closing cover 21, the condition inside the crushing box 20 can be observed, which is convenient for processing the components inside the crushing box body 20. When the opening and closing cover 21 is closed, the crushing box body 20 is in a closed state, ensuring the safety performance during the crushing process.

[0050] Furthermore, the crushing device 50 includes a crushing shaft 51, six support plates 52, six mounting shafts 53, a number of crushing knives 54, and a serrated arc plate 55. Among them, the crushing shaft 51 passes through and is rotatably arranged on the crushing box body 20, and five of the support plates 52 are evenly sleeved on the crushing shaft 51. Specifically, the support plate 52 has a hexagonal structure, and the six mounting shafts 53 respectively pass through the corresponding corners of the support plate 52 and are arranged parallel to the crushing shaft 51. A number of crushing knives 54 are spaced apart on the mounting shafts 53. The arc of the serrated arc plate 55 is similar to the inner wall of the crushing box body 20, so that the serrated arc plate 55 can be fixed closely to the crushing box body 20. In a specific practice, since the crushing knives 54 are spaced apart from each other and are also spaced apart from the crushing shaft 51, they can stir the waste while achieving crushing, effectively preventing the waste from being stuck or being difficult to be crushed by the crushing knives 54. In addition, the gap between the crushing knives 54 and the serrated arc plate 55 can slow down the wear of the crushing knives 54 and prevent the crushing knives 54 and the serrated arc plate 55 from being stuck by the waste.

[0051] As Figure 6 shown, the waste treatment equipment of this embodiment further includes a motor 12 installed on the base 10. The output shaft of the motor 12 is respectively connected to the crushing shaft 51 and the feeding shaft 32 through a pulley and belt structure, which can synchronously coordinate the opening and closing operations of feeding and crushing, and also reduce the cost of the equipment. Furthermore, the feeding shaft 32 can be connected to the belt conveyor and the chain plate conveyor 35 through a gear and chain structure, further reducing the investment in power components.

[0052] As Figure 7 shown, the motor 12 is arranged on the base 10 through a bearing plate 11, and a linear hole 111 is provided on the bearing plate 11. By moving the motor 12 along the linear hole 111, according to the tightness of the belt, it is beneficial to the stable drive of the motor 12.

[0053] In summary, the working mechanism of the waste treatment equipment in this embodiment is as follows: When waste needs to be crushed, the motor is started, and the crushing shaft and the feeding shaft are driven to rotate through the pulley and belt structure, and the belt conveyor and the chain plate conveyor are driven to work through the gear and chain structure. When the waste to be crushed is wood waste, the wood waste is placed on the chain plate conveyor through the conveying device or manually. The chain plate conveyor promotes the wood waste to be conveyed to its end, and is bitten by the feeding knife and brought into the crushing box body, and is repeatedly crushed through the interaction between the crushing knife and the serrated arc plate. Finally, the crushed waste that meets the crushing size requirements leaks out through the leakage port at the bottom of the crushing box body and is collected and recycled. Similarly, when the waste to be crushed is stone waste, the stone waste is placed on the belt conveyor through the conveying device or manually. The belt conveyor conveys the stone waste to its end and drops into the crushing box body, and is repeatedly crushed through the interaction between the crushing knife and the serrated arc plate. Finally, the crushed waste that meets the crushing size requirements leaks out through the leakage port at the bottom of the crushing box body and is collected and recycled.

[0054] Embodiment 2

[0055] As Figure 8 shown, the difference between this embodiment and Embodiment 1 is that the waste treatment equipment for construction engineering in this embodiment further includes a dust removal device 60 communicated with the crushing box body 20.

[0056] Furthermore, the dust removal device 60 includes a transfer box body 61, a wind box 62 and a collection nozzle 63. Among them, the transfer box body 61 is installed at the lower part of the crushing box body 20 and is inclined, and a sieve mesh is provided at the bottom of the transfer box body 61; the wind box 62 is arranged on the side of the crushing box body 20, and the transfer box body 61 and the wind box 62, and the wind box 62 and the collection nozzle 63 are communicated through pipelines. Specifically, the wind blades of the wind box 62 are installed on the crushing shaft 51. During the rotation of the crushing shaft 51, the wind blades of the wind box 62 are driven to rotate, so that the dust generated by crushing in the crushing box body 20 is sucked out and enters the collection nozzle 63 through the pipeline. By sleeving a dust collection device at the other end of the collection nozzle 63, the dust can be completely removed to achieve a dust-free effect.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
