Description

Technical Field

[0001] This utility model relates to the field of recycling technology, specifically to an engineering waste recycling device. Background Technology

[0002] Construction waste refers to various solid wastes generated during construction, demolition, decoration, and renovation. These wastes are mainly classified into the following categories according to their type: Demolition waste: concrete, mortar, bricks, tiles, ceramics, stone, metal, wood, and other wastes generated during the demolition of various buildings, pipelines, roads, and bridges; Construction waste: concrete, asphalt mixtures, mortar, formwork, and other waste materials generated during the construction, renovation, and expansion of various buildings, pipelines, roads, and bridges; and Waste mud: waste and residual mud generated during the construction of pile foundations, foundation pit retaining structures, slurry shield tunneling, and underground pipeline excavation of various buildings and structures.

[0003] Construction waste recycling equipment refers to mechanical equipment specifically designed for the treatment and recycling of construction waste. This equipment can effectively separate, crush, pulverize, screen, transport, and reuse waste, thereby reducing environmental pollution and improving resource utilization.

[0004] However, when using shredders for recycling wood-based engineering waste to shred relatively smooth wood, the excessive smoothness of the wood surface reduces the contact points with the blades or hammers inside the shredder, which may make it difficult for the wood to be effectively gripped and shredded, ultimately affecting the shredding efficiency of the equipment. Therefore, it does not meet the existing needs, and we have proposed an engineering waste recycling device. Utility Model Content

[0005] The purpose of this utility model is to provide an engineering waste recycling device to solve the problems mentioned in the background art, such as the fact that when using a shredder-type recycling device for crushing wood-type engineering waste, the surface of the wood is too smooth, which reduces the contact points with the blades or hammers inside the shredder, which may make it difficult for the wood to be effectively grasped and crushed, and may ultimately affect the crushing efficiency of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engineering waste recycling device, including a wood shredder. A feed inlet is provided on one side of the upper surface of the wood shredder. A stepper motor is fixedly installed inside the casing of the wood shredder on one side of the feed inlet. The output shaft of the stepper motor is connected to a concave rotating shaft via a coupling. The middle position of the outer surface of the concave rotating shaft is concave, and a metal sleeve is movably fitted at the middle position of the concave part of the outer surface of the concave rotating shaft. The lower end face of the metal sleeve is connected to a first rotating shaft connecting rod via a rotating shaft. The lower end face of the first rotating shaft connecting rod is connected to a second rotating shaft connecting rod via a rotating shaft. A guide sleeve is movably fitted on the lower side of the outer surface of the second rotating shaft connecting rod, and a lower pressure plate is fixedly connected to the lower end face of the second rotating shaft connecting rod.

[0007] Preferably, a control panel is fixedly installed on the outer surface of the wood shredder on the other side of the feed inlet, and the wood shredder and the stepper motor are electrically connected to the control panel.

[0008] Preferably, a guide rod is fixedly provided on one side of the upper surface of the lower pressure plate, and the guide rod is movably inserted into the interior of the wood shredder housing.

[0009] Preferably, the lower pressure plate has multiple cylindrical grooves inside, each containing a spring. The lower end face of the spring is connected to a metal ring, and the axis of the metal ring is connected to a connecting rod. The lower end face of the connecting rod is fixedly connected to a rubber push head located below the lower pressure plate.

[0010] Preferably, the outer surface of the metal ring is in contact with the inner wall of the cylindrical groove, and the metal ring and the cylindrical groove are slidably connected.

[0011] Preferably, the front end of the concave rotating shaft is located inside the wood shredder housing, and the concave rotating shaft located inside the wood shredder housing is connected to the wood shredder via a roller bearing.

[0012] Preferably, a protective cover plate is provided above the stepper motor on the outer surface of the wood shredder, and the wood shredder is fixed to the protective cover plate by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, when relatively smooth wood is added into the feed inlet, uses a stepper motor to cyclically push the lower pressure plate and the rubber push head connected to the lower end face of the lower pressure plate downwards. The downward-pushing rubber push head applies a downward pressure to the wood, which helps the blades or hammers inside the wood shredder to engage with the wood, thereby reducing the time required for the wood shredder to engage with the relatively smooth wood. Through the above technical solution, the shredding efficiency of the equipment for relatively smooth wood is improved.

[0015] 2. This utility model indirectly connects the rubber push head to a spring located inside the cylindrical groove. The spring force allows the rubber push head to move up and down. The spring force also prevents the rubber push head from getting stuck on the upper surface of the wood inside the feed inlet and being unable to move downwards, which would otherwise cause the stepper motor used to drive the lower pressure plate to jam. This technical solution improves the flexibility of the structure. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The wood shredder 1 (model BY), stepper motor 3 (model DM542) and spring 11 (model JX110) mentioned in this utility model can be obtained from the market or through private customization.

[0023] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides an engineering waste recycling device, including a wood crusher 1. A feed inlet 2 is provided on one side of the upper end face of the wood crusher 1. A stepper motor 3 is fixedly installed inside the housing of the wood crusher 1 on one side of the feed inlet 2. The output shaft of the stepper motor 3 is connected to a concave rotating shaft 4 through a coupling. The middle position of the outer surface of the concave rotating shaft 4 is concave, and a metal sleeve 5 is movably sleeved at the middle position of the concave part of the outer surface of the concave rotating shaft 4. The lower end face of the metal sleeve 5 is connected to a first rotating shaft connecting rod 6 through a rotating shaft. The lower end face of the first rotating shaft connecting rod 6 is connected to a second rotating shaft connecting rod 7 through a rotating shaft. A guide sleeve 8 is movably sleeved on the lower side of the outer surface of the second rotating shaft connecting rod 7, and a lower pressure plate 9 is fixedly connected to the lower end face of the second rotating shaft connecting rod 7.

[0024] As a preferred technical solution in this embodiment, such as Figure 2 As shown, a control panel 16 is fixedly installed on the outer surface of the wood shredder 1 on the other side of the feed inlet 2, and the wood shredder 1 and the stepper motor 3 are electrically connected to the control panel 16; the wood shredder 1 and the stepper motor 3 can be controlled through the control panel 16.

[0025] As a preferred technical solution in this embodiment, such as Figure 3 and Figure 4 As shown, the lower pressure plate 9 has multiple cylindrical grooves 10 inside, each containing a spring 11. A metal ring 12 is connected to the lower end of the spring 11, and a connecting rod 13 is connected to the axis of the metal ring 12. A rubber pusher head 14 located below the lower pressure plate 9 is fixedly connected to the lower end of the connecting rod 13. The outer surface of the metal ring 12 is in contact with the inner wall of the cylindrical groove 10, and the metal ring 12 and the cylindrical groove 10 are slidably connected. When relatively smooth wood is added into the feed inlet 2, the stepper motor 3 is started, and the stepper motor... 3 can drive the concave rotating shaft 4 connected to it to rotate. When the concave rotating shaft 4 rotates, the metal sleeve 5, which is movably sleeved on the concave part of the outer surface of the concave rotating shaft 4, will revolve around the connection between the concave rotating shaft 4 and the stepper motor 3. The revolving metal sleeve 5 can drive the lower pressure plate 9, which is connected to it through the first rotating shaft connecting rod 6 and the second rotating shaft connecting rod 7, to move up and down cyclically. And through the guide sleeve 8 sleeved on the outer surface of the second rotating shaft connecting rod 7, the second rotating shaft connecting rod 7 and the lower pressure plate 9 can only move up and down cyclically in a vertical state.

[0026] When the lower pressure plate 9 moves downward, the rubber push head 14 connected to the lower end face of the lower pressure plate 9 will move downward along with it. The downward moving rubber push head 14 can apply a downward pressure to the wood in the feed port 2. This downward pressure can help the blades or hammers inside the wood crusher 1 to engage with the wood, thereby reducing the time required for the wood crusher 1 to engage with the relatively smooth wood. Through this embodiment, the crushing efficiency of the equipment for relatively smooth wood is improved.

[0027] The rubber pusher head 14 is indirectly connected to the spring 11 located inside the cylindrical groove 10 through the connecting rod 13 and the metal ring 12. The spring force of the spring 11 allows the rubber pusher head 14 to move up and down. The spring force of the spring 11 can prevent the rubber pusher head 14 from getting stuck on the upper surface of the wood inside the feed port 2 and being unable to move down further, which would eventually cause the stepper motor 3 used to drive the lower pressure plate 9 to get stuck. The above technical solution improves the flexibility of the structure.

[0028] As a preferred technical solution in this embodiment, such as Figure 4 As shown, a guide rod 15 is fixedly provided on one side of the upper end face of the lower pressure plate 9. The guide rod 15 is movably inserted into the interior of the wood shredder 1 housing. The guide rod 15, which is fixed to the upper end face of the lower pressure plate 9 and movably inserted into the interior of the wood shredder 1, can improve the stability of the lower pressure plate 9 and prevent it from tilting.

[0029] As a preferred technical solution in this embodiment, such as Figure 3 As shown, the front end of the concave rotating shaft 4 is located inside the housing of the wood shredder 1, and the concave rotating shaft 4 located inside the housing of the wood shredder 1 is connected to the wood shredder 1 by a roller bearing; the roller bearing structure between the wood shredder 1 and the concave rotating shaft 4 can ensure the stability of the rotating concave rotating shaft 4.

[0030] A protective cover plate is provided above the stepper motor 3 on the outer surface of the wood shredder 1, and the wood shredder 1 is fixed to the protective cover plate with screws; the protective cover plate can protect the stepper motor 3, and when the stepper motor 3 fails, the protective cover plate can be removed to repair the stepper motor 3.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
