Description

Technical Field

[0001] The present application relates to the field of construction waste treatment, and in particular, to a construction waste treatment system. Background Art

[0002] A large amount of waste chips are generated during the construction crushing process. The waste chips adhere to the equipment or some protective covers and need to be cleaned in a timely manner.

[0003] In the related art, the waste chips are often directly cleaned by using an air suction pipe to align with the waste chips to be cleaned and absorb them. In some solutions, in order to improve the cleaning effect of the construction waste treatment, a chip cleaning brush is provided to sweep the waste chips, so as to improve the effect of absorbing the waste chips.

[0004] In view of the above related art, the inventor believes that there are the following defects:

[0005] When the chip cleaning brush sweeps the waste chips, it is easy to cause small particle waste chips to float into the air, and it is difficult to completely collect the waste chips; although some protective covers are provided to reduce the probability of waste chips floating into the air, when it comes to the surface depressions or protrusions of the mechanical parts with broken material dust that need to adsorb waste chips, it is difficult for the protective cover to completely abut against the mechanical parts with broken material dust where there are waste chips, so that small particle waste chips will float into the air at the gap between the protective cover and the mechanical parts with broken material dust, and it is difficult to completely and thoroughly clean the waste chips. Summary of the Invention

[0006] In order to improve the problem of difficult and incomplete thorough cleaning of waste chips, the present application provides a construction waste treatment system.

[0007] The construction waste treatment system provided by the present application adopts the following technical solutions:

[0008] A construction waste treatment system includes: a first crusher, a second crusher, a receiving hopper, a construction waste treatment device, a first conveyor and a second conveyor;

[0009] The first crusher is used to receive the construction waste to be crushed; the first conveyor is used to convey the crushed materials discharged from the first crusher to the second crusher, and the second conveyor is used to output the crushed materials discharged from the second crusher;

[0010] The receiving hopper is located below the first conveyor and the second conveyor;

[0011] The construction waste treatment device is arranged on a movable carrier; the construction waste treatment device includes:

[0012] A chip suction pipe, a storage tank, and a chip suction pump for sucking waste chips into the storage tank through the chip suction pipe for storage and collection; the construction waste treatment device further includes: a chip cleaning brush disposed on the chip suction pipe; a closing control member forming a waste chip diversion cavity communicating with the chip suction pipe; an expansion control member forming a control chamber with variable space size; a driving member for driving the closing control member to move to a first position close to a first crusher, a second crusher, a receiving hopper, the first crusher, the second crusher, the receiving hopper with chip dust and away from the mechanical components with chip dust to a second position; and for injecting a fluid medium into the control chamber to cause the expansion control member to expand to an expanded state; and for withdrawing the fluid medium from the control chamber to cause the expansion control member to contract to a contracted state; wherein when the closing control member moves to the first position, the expansion control member expands to the expanded state, and the expansion control member forms a flexible sealing area in contact with the mechanical components with chip dust between the closing control member and the mechanical components with chip dust; the flexible sealing area communicates with the waste chip diversion cavity; the driving member also drives the chip cleaning brush to move.

[0013] By adopting the above technical solution, the waste chip diversion cavity of the closing control member is used to adsorb the waste chips by the chip suction pipe in a relatively closed space, and the waste chips are cleaned by the chip cleaning brush in the relatively closed space, so that the waste chips are separated from the mechanical components with chip dust. At the same time, the waste chips will not overflow outward and are better retained in the relatively closed chamber to be absorbed by the chip suction pipe, and the effect of absorbing waste chips is better. In addition, by using the setting of the expansion control member, when the surface of the mechanical components with chip dust is uneven, the expansion control member is in the expanded state, and the expansion control member abuts against the uneven surface of the mechanical components with chip dust, which can ensure the sealing performance of the waste chip diversion cavity, thereby preventing the waste chips from overflowing outward and floating in the air when the chip cleaning brush sweeps the waste chips, and better cleaning and absorbing the waste chips into the storage tank.

[0014] Optionally, a rigid telescopic member is disposed in the control chamber; the rigid telescopic member is connected to the inner wall surface of the control chamber; when the expansion control member is in the expanded state, the rigid telescopic member extends; when the expansion control member is in the contracted state, the rigid telescopic member contracts; the rigid telescopic member is used to form an annular telescopic area in the control chamber, so that when the expansion control member is in the expanded state, a circular flexible sealing area and an annular control chamber are formed; the end of the rigid telescopic member forms a narrow edge portion connected to the control chamber, so that the expansion control member forms a narrow edge abutting portion abutting against the mechanical components with chip dust.

[0015] By adopting the above technical solution, the rigid telescopic member forms an annular telescopic region to limit the position of the expansion control member after expansion. The expansion control member expands along the annular telescopic region, thereby preventing the expansion control member from expanding towards the waste chip diversion chamber and preventing the expansion control member from expanding to a position where it blocks the chip suction pipe. The end of the expansion control member is narrowed by connecting the narrow edge portion to the inner wall surface of the control chamber. When the expansion control member abuts against the mechanical component with shredded dust, the expansion control member forms a narrow edge abutting portion to reduce the contact area between the expansion control member and the mechanical component with shredded dust, thereby ensuring a larger contact area between the waste chips and the waste chip diversion chamber and greatly improving the effect of absorbing the waste chips.

[0016] Optionally, a spacer region is formed between the inner wall surface of the waste chip diversion chamber and the outer wall surface of the chip suction pipe; the chip cleaning brush is disposed in the spacer region.

[0017] By adopting the above technical solution, the chip cleaning brush is located outside the chip suction pipe. The chip suction pipe sweeps the waste chips on the mechanical component with shredded dust and separates them from the mechanical component with shredded dust. Then, the port of the chip suction pipe is unobstructed, better ensuring the suction force and avoiding the situation where the chip cleaning brush causes suction loss in the chip suction pipe.

[0018] Optionally, the chip suction pipe includes a connecting pipe section and a movable pipe section; the movable pipe section is connected to the connecting pipe section; the driving member is further configured to drive the movable pipe section to move, forming a movable cleaning region located in the waste chip diversion chamber; the chip cleaning brush is disposed on the movable pipe section.

[0019] By adopting the above technical solution, the movable pipe moves in the chip suction diversion chamber, so that the chip cleaning brush cleans the waste chips at different positions, increasing the effect of treating construction waste. In addition, when the movable pipe moves to different positions, the waste chips at different positions can be strongly sucked away, thereby improving the chip suction effect on the waste chips.

[0020] Optionally, a plurality of chip cleaning brushes are provided, and the plurality of chip cleaning brushes are circumferentially and arrayedly distributed around the axis of the chip suction pipe; the driving member is configured to drive the plurality of chip cleaning brushes to rotate around the axis of the chip suction pipe.

[0021] By adopting the above technical solution, the chip cleaning brush cleans the waste chips in a rotating manner, thereby generating a stronger force for treating construction waste, enabling the waste chips to be better cleaned to the extent of being separated from the mechanical component with shredded dust, and increasing the effect of treating construction waste.

[0022] Optionally, an elastic member and a guiding member are provided on the chip suction pipe; a guiding portion is formed on the chip cleaning brush; the guiding member forms a guiding track; the elastic member is used to closely attach the guiding portion to the guiding track; the guiding track extends around the axis of the chip suction pipe; at least one guiding protrusion or at least one guiding depression is formed on the guiding track; when the driving member drives the chip cleaning brush to rotate around the axis of the chip suction pipe, the chip cleaning brush reciprocates in the axial direction of the chip suction pipe.

[0023] By adopting the above technical solution: since the chip cleaning brush reciprocates along the axis of the chip suction pipe, the pressure between the chip cleaning brush and the mechanical component with shredded materials and dust will increase and decrease, or the pressure between the chip cleaning brush and the mechanical component with shredded materials and dust will increase and the two will separate. Therefore, the effect of treating construction waste can be improved by increasing the pressure. The pressure between the chip cleaning brush and the mechanical component with shredded materials and dust decreases or the two separate so that the waste chips can be better sucked into the chip suction pipe. When the pressure decreases or they separate, there is an obvious gap between the chip suction pipe and the mechanical component with shredded materials and dust, facilitating the suction of waste chips into the storage tank.

[0024] Optionally, the closing control member includes: a sliding ring, a transmission member, and extension legs; a plurality of extension legs are provided; the sliding ring is connected to the chip suction pipe; the transmission member is used to connect the extension legs to the sliding ring; the driving member is used to drive the sliding ring to move, so that the extension legs and the transmission member move closer to and farther away from the mechanical component with shredded materials and dust; the driving member is also used to drive the plurality of extension legs to expand and contract through the transmission member; when the chip suction pipe moves closer to the mechanical component with shredded materials and dust, after the driving member drives the plurality of extension legs to expand, it drives the extension legs to move closer to the mechanical component with shredded materials and dust; when the chip suction pipe moves away from the chip suction carrier, after the driving member drives the plurality of extension legs to contract, it drives the extension legs to move away from the mechanical component with shredded materials and dust; an elastic film is provided outside the plurality of extension legs, and a waste chip diversion chamber is formed in the elastic film.

[0025] By adopting the above technical solution, the waste chip diversion chamber is formed by fixing an elastic membrane on the extension leg. The extension leg moves closer to and away from the axis of the chip suction pipe, which can make the positions where the expansion control member contacts the mechanical component with shredded dust approach and move away from each other. Then, when the expansion control member and the closing control member move closer to the mechanical component with shredded dust, the extension leg is moved away from the axis of the chip suction pipe, and then the expansion control member and the closing control member are moved closer. After the chip suction pipe finishes sucking chips, the multiple extension legs are moved closer to each other. As a result, the expansion control member will scrape on the mechanical component with shredded dust, gathering the mechanical component with shredded dust near the axis of the chip suction pipe. This realizes that after the chip suction is completed, the mechanical component with shredded dust is scraped again, making the waste chips better scraped off the mechanical component with shredded dust. And after gathering, it is easier to be absorbed by the chip suction pipe, thus improving the treatment effect of construction waste. In addition, since the multiple extension legs move away from the axis of the chip suction pipe, the multiple extension legs can move to different positions, enabling the expansion control member to form narrow-edge abutting parts of different sizes. Then, when there are large protrusions or depressions on the mechanical component with shredded dust and it is difficult for the expansion control member to contact the mechanical component with shredded dust after expansion, the size enclosed by the narrow-edge abutting part can be reduced for adaptation, so as to clean the waste chips on the mechanical component with shredded dust with a relatively tricky shape and structure.

[0026] Optionally, a plurality of chip cleaning brushes are provided, and the plurality of chip cleaning brushes are circumferentially and arrayedly distributed around the axis of the chip suction pipe; the driving member is used to drive the plurality of chip cleaning brushes to rotate or move closer to and away from the axis of the chip suction pipe.

[0027] By adopting the above technical solution, when the chip cleaning brush moves closer to the axis of the chip suction pipe, it can gather the waste chips on the mechanical component with shredded dust, thus realizing gathering while cleaning the waste chips.

[0028] Optionally, the chip cleaning brush is arranged on the extension leg and the chip cleaning brush is a flexible brush body.

[0029] By adopting the above technical solution, the chip cleaning brush is arranged on the extension leg. Since the extension leg moves closer to and away from the axis of the chip suction pipe, it realizes cleaning and gathering the waste chips by the chip cleaning brush.

[0030] Optionally, the fluid medium is water or antistatic liquid.

[0031] By adopting the above technical solution, the fluid medium can reduce or eliminate static electricity on the expansion control member, thereby avoiding the situation where small particle waste adheres to the expansion control member. The adhesion of small particle waste to the expansion control member will cause the small particle waste to not be absorbed. As the expansion control member moves, shrinks, expands, and the adhered small particle waste gradually increases, it will cause the small particle waste to fall off the control member, thus affecting waste collection. Therefore, by reducing or eliminating static electricity, the effect of construction waste treatment and collection is improved.

[0032] In summary, the beneficial technical effects of this application are as follows:

[0033] When the surface of the mechanical component with chip dust is uneven, by using the expansion control member in the expanded state and making the expansion control member abut against the uneven surface of the mechanical component with chip dust, the sealing performance of the waste chip diversion chamber can be ensured, thereby preventing the situation where waste chips overflow outward and float in the air when the chip cleaning brush cleans the waste chips, and better completely cleaning and absorbing the waste chips into the storage tank.

[0072] The following further elaborates on this application in conjunction with the attached Figure 1-26 drawings for a more detailed description.

[0073] An embodiment of this application discloses a construction waste treatment system.

[0074] Referring to Figure 1-2 , a construction waste treatment system includes: a first crusher 21, a second crusher 22, a receiving hopper 27, a construction waste treatment device, a first conveyor 23 and a second conveyor 24; both the first conveyor 23 and the second conveyor 24 are conveyors.

[0075] The first crusher 21 is used to hold the construction waste to be crushed; the first conveyor 23 is used to convey the crushed materials discharged from the first crusher 21 to the second crusher 22, and the second conveyor 24 is used to output the crushed materials discharged from the second crusher 22;

[0076] The receiving hopper 27 is located below the first conveyor 23 and the second conveyor 24;

[0077] Specifically, the conveying directions of both the first conveyor 23 and the second conveyor 24 are inclined upward. At this time, both the first crusher 21 and the second crusher 22 are placed on the ground. The first crusher 21 and the second crusher 22 are directly purchased products. Therefore, the inclined upward setting of the first conveyor 23 is to be able to send the construction waste discharged from the discharge port of the first crusher 21 into the feed port of the second crusher 22, so as to enable the first crusher 21 and the second crusher 22 to be directly placed on the ground, making the use process more stable.

[0078] Specifically, a first filter member 25 is provided at a position of the first conveyor member 23 near the first crusher 21; a second filter member 26 is provided at a position of the second conveyor member 24 near the second crusher 22; a receiving hopper 27 is provided below both the first filter member 25 and the second filter member 26. Among them, both the first filter member 25 and the second filter member 26 are filter mesh plates. Multiple strip-shaped through slots are formed on the filter mesh plate, and the through slots are used to pass the small-particle construction waste that meets the requirements, and then intercept the large-particle construction waste that does not meet the requirements. It realizes the separate addition of the large-particle construction waste that does not meet the requirements into the second crusher 22 for re-crushing. The receiving hopper 27 is used to receive the construction waste that meets the requirements, so as to facilitate its transportation and use. More specifically, a storage box is provided at a position of the second conveyor member 24 away from the second crusher 22. The construction waste with too large particles that does not meet the requirements on the second conveyor member 24 will fall into the storage box along the transportation of the second conveyor member 24. The construction waste in the storage box does not meet the requirements and can be taken out manually later and crushed manually.

[0079] Specifically, filter surfaces are formed on both the first filter member 25 and the second filter member 26; conveying surfaces are formed on both the first conveyor member 23 and the second conveyor member 24; an angle of -° is formed between the filter surface and the conveying surface. Among them, the first conveyor member 23 can convey the construction waste towards the second crusher 22 or towards the first crusher 21. When conveying towards the first crusher 21, the construction waste will be intercepted by the first filter member 25. At the same time, the first conveyor member can also stop conveying the construction waste. Thus, it can better enable the construction waste that meets the requirements on the first conveyor member 23 to flow onto the first filter member 25 and enter the receiving hopper 27 through the first filter member 25 for storage, facilitating the separation of the construction waste that meets the requirements from the construction waste that does not meet the requirements.

[0080] Specifically, a first magnetic member 28 is provided above the first conveyor member 23, and a second magnetic member 29 is provided above the second conveyor member 24; both the first magnetic member 28 and the second magnetic member 29 are used to adsorb metals in the construction waste. Both the first magnetic member 28 and the second magnetic member 29 are electromagnets. Both the first magnetic member 28 and the second magnetic member 29 are used to adsorb and remove metals in the construction waste. Among them, a robotic arm is further included. The robotic arm is connected to the first magnetic member 28 and the second magnetic member 29, and the robotic arm is used to drive the first magnetic member 28 and the second magnetic member 29 to move, so as to be able to move the first magnetic member 28 and the second magnetic member 29 to the parts outside the first conveyor member 23 and the second conveyor member 24, thus facilitating the removal of metals in the construction waste.

[0081] Specifically, the first filter member 25 is further configured to form a first protection area with a plurality of first filter holes at the edge of the first conveyor member 23; the second filter member 26 is further configured to form a second protection area with a plurality of second filter holes at the edge of the second conveyor member 24. The first protection area and the second protection area are formed by a mesh plate to prevent particles in the construction waste from spilling outwards.

[0082] The construction waste treatment device is disposed on a movable carrier; the construction waste treatment device includes:

[0083] A chip suction pipe 1, a storage tank 2, and a chip suction pump 3 that sucks waste chips into the storage tank 2 through the chip suction pipe 1 for storage and collection. Among them, the chip suction pipe 1, the storage pipe, and the chip suction pump 3 are integrated on a movable carrier 4, so that the chip suction pipe 1 can perform chip suction treatment for different positions or different devices. The chip suction pump 3 utilizes the flow of air to generate suction at the port of the chip suction pipe 1, sucks the waste chips into the chip suction pipe 1, and then sucks them into the storage tank 2 for storage and collection.

[0084] Referring to Figure 1-5 , the construction waste treatment device further includes: a chip cleaning brush 5, a closing control member 6, an expansion control member 7, and a driving member 8.

[0085] The chip cleaning brush 5 is arranged on the chip suction pipe 1. The closing control member 6 forms a waste chip diversion cavity communicating with the chip suction pipe 1. In this actual example, the closing control member 6 adopts a pipe body, preferably a flared pipe body. The expansion control member 7 forms a control chamber 71 with variable space size. In this embodiment, the expansion control member 7 adopts an annular ring 72 surrounded by an elastic rubber membrane. The cavity inside the annular ring 72 is the control chamber 71. The expansion control member 7 and the closing control member 6 are fixed together. The driving member 8 is used to drive the closing control member 6 to move to a first position close to a first crusher, a second crusher, a receiving hopper, the first crusher, the second crusher, the receiving hopper with chip dust and move away from the mechanical components with chip dust to a second position; and is used to inject a fluid medium into the control chamber 71 to cause the expansion control member 7 to expand to an expanded state; and is used to draw the fluid medium out of the control chamber 71 to cause the expansion control member 7 to contract to a contracted state. The driving member 8 also drives the chip cleaning brush 5 to move. In this embodiment, the driving member 8 includes: a first electric push rod 81, a second electric push rod 82 and a pump body 83. The fluid medium adopts air in this embodiment. The pump body 83 is communicated with the control chamber 71. The pump body 83 injects air into the control chamber 71 to make the expansion control member 7 in the expanded state and the contracted state. The first electric push rod 81 is installed on the chip suction pipe 1. The output end of the first electric push rod 81 is connected to the closing control member 6. The closing control member 6 is slidably connected to the chip suction pipe 1. The first electric push rod 81 drives the closing control member 6 to move to the first position and the second position. The second electric push rod 82 is located inside the waste chip diversion cavity. The second electric push rod 82 drives the chip cleaning brush 5 to move, so that the chip cleaning brush 5 cleans the waste chips on the mechanical components with chip dust.

[0086] Wherein, when the closing control member 6 moves to the first position, the expansion control member 7 expands to an expanded state, and the expansion control member 7 forms a flexible sealing area 73 in contact with the mechanical components with chip dust between the closing control member 6 and the mechanical components with chip dust. The flexible sealing area 73 is communicated with the waste chip diversion cavity.

[0087] By adopting the above technical solution, the waste chip diversion chamber of the closed control member 6 is used to adsorb waste chips by the chip suction pipe 1 in a relatively closed space, and the waste chips are cleaned by the chip cleaning brush 5 in a relatively closed space, so that the waste chips are separated from the mechanical components with broken materials and dust. At the same time, the waste chips will not overflow outward, but better stay in the relatively closed chamber and be absorbed by the chip suction pipe 1, and the effect of absorbing waste chips is better. In addition, by setting the expansion control member 7, when the surface of the mechanical component with broken materials and dust is uneven, the expansion control member 7 is in an expanded state, and the expansion control member 7 abuts against the uneven surface of the mechanical component with broken materials and dust, which can ensure the sealing performance of the waste chip diversion chamber, so as to prevent the waste chips from overflowing outward and floating in the air when the chip cleaning brush 5 sweeps the waste chips, and better clean and absorb the waste chips completely into the storage tank 2.

[0088] Referring to Figure 10 、 12 、15, 17, 20, 24 - 25, in other embodiments, a rigid telescopic member 9 is provided in the control chamber 71. In a specific solution, the rigid telescopic member 9 adopts a multi-section low-friction telescopic rod 91. The rigid telescopic member 9 is connected to the inner wall surface of the control chamber 71; in a specific solution, the rigid telescopic member 9 is a plurality of multi-section low-friction telescopic rods 91, and the plurality of telescopic rods 91 are arranged in a circular pattern, so that the rigid telescopic member 9 is used to form an annular telescopic area in the control chamber 71. An elastic rubber membrane is wrapped around the plurality of telescopic rods 91, and both ends of the telescopic rod 91 are fixed to the elastic telescopic membrane. Therefore, when the expansion control member 7 is in an expanded state, the rigid telescopic member 9 extends; when the expansion control member 7 is in a contracted state, the rigid telescopic member 9 contracts.

[0089] In addition, in a specific solution, the side part of the telescopic rod 91 is fixed to the elastic rubber membrane. When the expansion control member 7 is in an expanded state, a circular flexible sealing area 73 and an annular control chamber 71 are formed. The annular control chamber 71 is formed by fixing the side of the telescopic rod 91 to the elastic rubber membrane. Since the elastic rubber membrane can only expand and contract along the direction of the extension and contraction of the telescopic rod 91 when the elastic rubber membrane expands, the annular control chamber 71 is formed. The circular flexible sealing area 73 is formed by the inner circle of the annular telescopic area. Therefore, when the expansion control member 7 contacts the mechanical component with broken materials and dust, the contact range between the expansion control member 7 and the mechanical component with broken materials and dust is an annular range, and the diameter of the telescopic rod 91 limits the contact range. Therefore, the contact area with the chip suction carrier can be reduced, preventing more waste chips from being squeezed by the expansion control member 7, avoiding the expansion of the expansion control member 7 towards the waste chip diversion chamber and avoiding the expansion of the expansion control member 7 to a position blocking the chip suction pipe 1.

[0090] In some more specific solutions, the end of the rigid telescopic member 9 forms a narrow-edge portion 92 connected to the control chamber 71, so that the expansion control member 7 forms a narrow-edge abutting portion that abuts against the mechanical component with chip dust. Among them, the narrow-edge portion 92 is an annular plate fixed to the end of the telescopic rod 91. One end of the annular plate facing away from the chip suction pipe 1 forms a chamfer, so that the lower part of the annular plate is a narrow edge. The elastic rubber membrane is fixed to the narrow-edge portion 92, so that the expansion control member 7 forms a narrow-edge abutting portion. The narrow-edge abutting portion is used to abut against the mechanical component with chip dust.

[0091] In some preferred solutions, the narrow-edge portion 92 being an annular plate is replaced with the narrow-edge portion 92 being a plurality of narrow blocks. The narrow blocks are fixed to the telescopic rod 91, so that the plurality of narrow blocks abut against the mechanical component with chip dust at the same time. Since the telescopic length of each telescopic rod 91 is determined by the degree to which the control chamber 71 can expand, the plurality of narrow blocks are located at different height positions and are adapted to some special shapes on the mechanical component with chip dust, such as inclined surfaces, concave surfaces and convex surfaces. The narrow blocks are in contact with the inclined surfaces, concave surfaces and convex surfaces, so that when the expansion control member 7 is in the expanded state, it can abut tightly against the inclined surfaces, concave surfaces and convex surfaces. The end of the expansion control member 7 is narrowed by the way the narrow-edge portion 92 is connected to the inner wall surface of the control chamber 71, and when the expansion control member 7 abuts against the mechanical component with chip dust, the expansion control member 7 forms a narrow-edge abutting portion to reduce the contact area between the expansion control member 7 and the mechanical component with chip dust, so as to more ensure the contact area between the waste chips and the waste chip diversion chamber, and greatly improve the effect of absorbing the waste chips.

[0092] In a more specific solution, an interval region is formed between the inner wall surface of the waste chip diversion chamber and the outer wall surface of the chip suction pipe 1. The chip cleaning brush 5 is arranged in the interval region. The chip cleaning brush 5 is located outside the chip suction pipe 1. The chip suction pipe 1 sweeps the waste chips on the mechanical component with chip dust and separates them from the mechanical component with chip dust, and then the port of the chip suction pipe 1 is not blocked, which better ensures the suction force and avoids the situation that the chip cleaning brush 5 causes suction loss of the chip suction pipe 1 inside the chip suction pipe 1.

[0093] Embodiment 2

[0094] Refer to Figure 11-12 , the difference from Embodiment 1 is that: the chip suction pipe 1 includes a connecting pipe section 11 and a movable pipe section 12. The movable pipe section 12 is connected to the connecting pipe section 11. The driving member 8 is also used to drive the movable pipe section 12 to move. An active cleaning area located in the waste chip diversion chamber is formed. The chip cleaning brush 5 is arranged on the movable pipe section 12. Among them, the connecting pipe is used to connect to the chip suction pump 3.

[0095] In a specific solution, the driving member 8 further includes a first driving motor 84. The movable pipe section 12 is rotatably connected to the connecting pipe section 11, and the first driving motor 84 drives the movable pipe section 12 to rotate. By moving the movable pipe in the chip suction and diversion chamber, the chip cleaning brush 5 can clean waste chips at different positions, improving the effect of treating construction waste. In addition, when the movable pipe moves to different positions, waste chips at different positions can be strongly sucked away, thus improving the chip suction effect on waste chips.

[0096] Embodiment 3

[0097] Referring to Figure 6-10 , the difference from Embodiment 1 is that multiple chip cleaning brushes 5 are provided, and the multiple chip cleaning brushes 5 are circumferentially arrayed around the axis of the chip suction pipe 1. The driving member 8 is used to drive the multiple chip cleaning brushes 5 to rotate around the axis of the chip suction pipe 1.

[0098] In a specific solution, the driving member 8 includes a second driving motor 85 and a rotating plate 851. The rotating plate 851 is rotatably connected to the movable pipe section 12. A carrier 41 is provided on the movable pipe section 12. The second driving motor 85 is installed on the carrier 41. The second driving motor 85 drives the rotating plate 851 to rotate, and multiple chip cleaning brushes 5 are installed on the rotating plate 851. Among them, the second driving motor 85 drives the rotating plate 851 to rotate by means of gear transmission or belt pulley transmission.

[0099] In some other embodiments, an elastic member 44 and a guiding member 43 are provided on the chip suction pipe 1. A guiding portion 42 is formed on the chip cleaning brush 5, and the guiding member 43 forms a guiding track. The elastic member 44 is used to closely attach the guiding portion 42 to the guiding track. The guiding track extends around the axis of the chip suction pipe 1.

[0100] The specific solution for the guiding member 43 is that the guiding member 43 is a circular ring plate. The guiding track formed on the guiding member 43 is a circular guide rail, and the guiding portion 42 formed on the chip cleaning brush 5 is a groove structure that slidably connects with the guide rail. Among them, at least one guiding protrusion 431 or at least one guiding depression 432 is formed on the guiding track, that is, there are protrusions and depressions on the circular guide rail. After the guiding portion 42 moves to the positions of the guiding protrusion 431 and the guiding depression 432, the guiding portion 42 drives the chip cleaning brush 5 to move along the axial direction of the chip suction pipe 1. When the driving member 8 drives the chip cleaning brush 5 to rotate around the axis of the chip suction pipe 1, the chip cleaning brush 5 reciprocally moves along the axial direction of the chip suction pipe 1. The chip cleaning brush 5 reciprocally moves along the axis of the chip suction pipe 1, then the pressure between the chip cleaning brush 5 and the mechanical component with shredded material and dust will become larger and smaller, or the pressure between the chip cleaning brush 5 and the mechanical component with shredded material and dust becomes larger and the two are separated, so that the effect of building waste treatment can be improved by increasing the pressure. The pressure between the chip cleaning brush 5 and the mechanical component with shredded material and dust becomes smaller or the two are separated in order to enable the waste chips to be better sucked into the chip suction pipe 1. When the pressure becomes smaller or they are separated, there is an obvious gap between the chip suction pipe 1 and the mechanical component with shredded material and dust, so as to facilitate sucking the waste chips into the storage tank 2.

[0101] Another specific solution for the guiding member 43 is that the guiding portion 42 contacts the guiding member 43, and the elastic member 44 presses the guiding portion 42 against the guiding member 43. The elastic member 44 is a spring, the elastic member 44 abuts against the rotating plate 851, the guiding portion 42 is slidably connected with the rotating plate 851, and the elastic member 44 exerts a downward acting force on the guiding portion 42.

[0102] Embodiment 4

[0103] Referring to Figure 13-24 , the difference from Embodiment 3 is that: the closing control member 6 includes: a sliding ring 61, a transmission member 62, and extension legs 63. A plurality of extension legs 63 are provided, and the sliding ring 61 is connected to the chip suction pipe 1. The transmission member 62 is used to connect the extension legs 63 with the sliding ring 61. The driving member 8 is used to drive the sliding ring 61 to move, so that the extension legs 63 and the transmission member move closer to and farther away from the mechanical component with shredded material and dust, and the driving member 8 is also used to drive the plurality of extension legs 63 to expand and contract through the transmission member 62. An elastic membrane 64 is arranged outside the plurality of extension legs 63, and a waste chip diversion chamber is formed in the elastic membrane 64.

[0104] Referring to Figure 13-17 , the first specific solution for the transmission member 62 and the driving member 8 in this embodiment is:

[0105] The transmission member 62 includes a plurality of telescopic tubes 621 and a connection block communicating with the plurality of telescopic tubes 621. A communication chamber 622 communicating with the plurality of telescopic tubes 621 is formed in the connection block. The driving member 8 includes a third electric push rod 86, a fourth electric push rod 87 and a push plate 88. The push plate 88 is arranged in the communication chamber 622. The third electric push rod 86 is used to push the push plate 88 to move in the communication chamber 622. The communication chamber 622 and the telescopic tubes 621 are filled with hydraulic oil. Thus, when the push plate 88 moves in the communication chamber 622, the plurality of telescopic tubes 621 are elongated or shortened by using the hydraulic oil, realizing the movement of the plurality of extension legs 63 closer to and farther from the axis of the chip suction tube 1. Wherein, the connection block is a circular block, and the connection block is located in the middle of the chip suction tube 1. The third electric push rod 86 is arranged on the sliding ring 61, and the fourth electric push rod 87 is arranged on the chip suction tube 1. The fourth electric push rod 87 is used to drive the sliding ring 61 to move on the chip suction tube 1.

[0106] When the chip suction tube 1 moves closer to the mechanical component with shredded materials and dust, after the driving member 8 drives the plurality of extension legs 63 to unfold, it drives the extension legs 63 to move closer to the mechanical component with shredded materials and dust; when the chip suction tube 1 moves away from the chip suction carrier, after the driving member 8 drives the plurality of extension legs 63 to contract, it drives the extension legs 63 to move away from the mechanical component with shredded materials and dust.

[0107] Wherein, the telescopic tube 621 is a horizontally arranged tube body. The telescopic tube 621 is connected to the communication chamber 622 through a fixed tube 626. Thus, the liquid in the communication chamber 622 enters the telescopic tube 621 through the fixed tube 626, enabling the telescopic tube 621 to expand and contract.

[0108] Refer to Figure 13-21 In this embodiment, the second specific solution regarding the transmission member 62 and the driving member 8 is:

[0109] The difference between this solution and the above-mentioned first specific solution is that the connection block is replaced with an annular block 623. The annular block 623 is located outside the chip suction tube 1, and the extension legs 63 and the transmission mechanism are both located in the inner ring of the annular block 623. Since in the above-mentioned first specific solution, both the connection block and the telescopic tube 621 will block part of the chip suction tube 1, thus affecting the suction force of the chip suction tube 1, while in this solution, there is no blockage in the middle of the chip suction tube 1, better preserving the suction force of the chip suction tube 1.

[0110] Refer to Figure 22-24 In this embodiment, the third specific solution regarding the transmission member 62 and the driving member 8 is:

[0111] The closed control member 6 includes: a sliding block 624 and a hinge rod 625; a plurality of hinge rods 625 are provided, and a plurality of extension legs 63 are hinged to the sliding ring 61, and a plurality of hinge rods 625 are hinged to the sliding block 624 and the extension legs 63; the driving member 8 includes a fifth electric push rod 89 and a sixth electric push rod 80, the fifth electric push rod 89 is fixed to the chip suction pipe 1, the fifth electric push rod 89 is used to drive the sliding ring 61 to move, the sixth electric push rod 80 is connected to the sliding ring 61, and the sixth electric push rod 80 is used to drive the sliding block 624 to move away from and close to the sliding ring 61. Thus, the driving member 8 is used to drive the sliding ring 61 and the sliding block 624 to move simultaneously and drive the sliding block 624 to move close to and away from the sliding ring 61. A socket is provided in the middle of the sliding block 624, and the size of the socket matches that of the chip suction pipe 1, and the socket is slidably connected to the chip suction pipe 1.

[0112] When the chip suction pipe 1 moves close to the mechanical component with shredded material dust, the driving member 8 drives the sliding block 624 to move close to the sliding ring 61 to deploy a plurality of extension feet; the driving member 8 drives the sliding block 624 and the sliding ring 61 to move close to the chip suction carrier simultaneously; when the chip suction pipe 1 moves away from the chip suction carrier, the driving member 8 drives the sliding block 624 to move away from the sliding ring 61 to contract a plurality of telescopic feet; the driving member 8 drives the sliding block 624 and the sliding ring 61 to move away from the chip suction carrier simultaneously.

[0113] The waste chip diversion chamber is formed by fixing an elastic membrane 64 on the extension legs 63. The extension legs 63 move close to and away from the axis of the chip suction pipe 1, which can make the positions where the expansion control member 7 contacts the mechanical component with shredded material dust approach and move away from each other. Then when the expansion control member 7 and the closed control member 6 move close to the mechanical component with shredded material dust, the extension legs 63 are driven to move away from the axis of the chip suction pipe 1, and then the expansion control member 7 and the closed control member 6 are moved closer. Then after the chip suction pipe 1 finishes sucking chips, the plurality of extension legs 63 are made to approach each other. Thus, the expansion control member 7 will scrape against the mechanical component with shredded material dust on the mechanical component with shredded material dust to gather the mechanical component with shredded material dust near the axis of the chip suction pipe 1. After the chip suction is completed, the mechanical component with shredded material dust is scraped again, so that the waste chips are better scraped off the mechanical component with shredded material dust, and after being gathered, they are more easily absorbed by the chip suction pipe 1, thereby improving the construction waste treatment effect.

[0114] Since multiple extension legs 63 move away from the axis of the dust suction pipe 1, the multiple extension legs 63 can be moved to different positions, enabling the expansion control member 7 to form narrow-edge abutting portions of different sizes. Then, when there are large protrusions or depressions on the mechanical component with shredded materials and dust, and it is difficult for the expansion control member 7 to contact the mechanical component with shredded materials and dust after expansion, the size enclosed by the narrow-edge abutting portion can be reduced for adaptation, so as to clean the waste chips on the mechanical component with shredded materials and dust with a relatively tricky shape structure. Specifically, when the expansion control member 7 contacts the mechanical component with shredded materials and dust, the contact position is a small-area protrusion, and there is a situation where the expansion control member 7 cannot fully contact the small-area protrusion, resulting in poor contact and inability to seal. Therefore, by changing the distance between the multiple extension legs 63, the abutting range of the narrow-edge abutting portion on the expansion control member 7 can be realized, and it can be better adapted to different situations for use.

[0115] Embodiment 5

[0116] The difference from Embodiment 3 is that the driving member 8 is used to drive the multiple chip cleaning brushes 5 to rotate or move closer to and away from the axis of the dust suction pipe 1. When the chip cleaning brush 5 moves closer to the axis of the dust suction pipe 1, the waste chips on the mechanical component with shredded materials and dust can be gathered, thus realizing the gathering of waste chips while cleaning. At this time, the driving member 8 adopts the structure of the transmission rod member and the sliding ring 61 in the above embodiment to realize the movement of the multiple chip cleaning brushes 5 closer to and away from the axis of the dust suction pipe 1. Or the driving member 8 adopts the structure of the sliding block 624, the articulated rod 625 and the sliding ring 61 in Embodiment 4 to realize the rotation of the chip cleaning brush 5 closer to and away from the axis of the dust suction pipe 1.

[0117] Embodiment 6

[0118] The difference from Embodiment 4 is that multiple chip cleaning brushes 5 are provided, and some of the chip cleaning brushes 5 are provided on the extension legs 63 and the chip cleaning brush 5 is a flexible brush body. For the convenience of distinction, the chip cleaning brush 5 provided on the extension leg 63 is defined as a sweeping brush. The sweeping brush is provided on the extension leg 63. Since the extension leg 63 will move closer to and away from the axis of the dust suction pipe 1, the sweeping brush realizes the gathering of waste chips while cleaning. The effect of the expansion control member 7 on gathering waste chips when the extension leg 63 contracts is increased.

[0119] Embodiment 7

[0120] Refer to Figure 1-2, different from Embodiment 1 in that: the fluidity medium is water or antistatic liquid. Preferably, antistatic liquid is used. The driving member 8 includes a liquid injection pipe, a driving liquid pump body 83 and a liquid storage box body 45. Additionally, the construction waste treatment device further includes a robotic arm 46. The chip suction pipe 1 is installed on the robotic arm 46, and the robotic arm 46 is arranged on the mobile carrier 4, so that the robotic arm 46 increases the selectivity of the moving position of the chip suction pipe 1. Both the liquid storage box body 45 and the driving liquid pump body 83 are arranged on the mobile carrier 4. The liquid injection pipe is communicated with the control chamber 71, and the driving liquid pump body 83 discharges the antistatic liquid from the liquid storage tank and adds it into the control chamber 71.

[0121] The fluidity medium can reduce or eliminate the static electricity on the expansion control member 7, thereby avoiding the situation that small particle waste chips adhere to the expansion control member 7. The adhesion of small particle waste chips to the expansion control member 7 will cause the small particle waste chips to not be absorbed. As the expansion control member 7 moves, shrinks, expands, and the adhered small particle waste chips gradually increase, the small particle waste chips will fall off the control member, thus affecting the waste chip collection. Therefore, by reducing or eliminating static electricity, the effect of construction waste treatment and collection is improved.

[0122] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
