[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Construction solid waste (SSD) treatment refers to the resource utilization of solid waste generated during the construction, renovation, and demolition of buildings to reduce the environmental burden caused by landfilling and dumping. Construction solid waste treatment involves classifying, processing, and reusing construction waste to transform it into renewable resources, such as recycled aggregates, permeable bricks, and other building materials, or for use in roadbed filling, ecological restoration, and other projects.

[0004] Construction waste treatment involves the relocation, leveling, site cleanup, loading, and transportation of construction waste. Currently, these processes require the coordinated or sequential operation of various engineering machinery. These machines need to enter the site simultaneously or sequentially to perform their operations, which not only makes the construction waste treatment process cumbersome but also makes it easy for interference to occur between the different machines.

[0005] In addition, existing construction waste treatment stations do not have material handling capabilities, requiring additional excavators, loading machines, etc., to grab materials, which are then transported to the construction waste treatment station by a feeder. The operation process is complicated, time-consuming, and labor-intensive. Summary of the Invention

[0030] In a typical embodiment of the present invention, such as Figure 1 As shown, a chain-bucket self-loading tracked mobile construction solid waste treatment station is proposed, which consists of a driving power unit 1, a chain bucket material handling unit 2, a processing unit 3, an external conveying unit 4, and a walking unit 5. All parts of this treatment station adopt a modular structure, which can be easily assembled, disassembled, and transported. The chain bucket material handling unit 2 is one module; the driving power unit 1, processing unit 3, and external conveying unit 4 share a housing and are combined into one module; four sets of walking units 5 form one module, for a total of three modules. The housing is used to install the driving power unit 1, processing unit 3, and external conveying unit 4. Corner fittings are provided at the bottom of the housing, and a turnlock is provided on the upper platform of the walking unit 5. The corner fittings and turnlock are used for positioning and fixing when the walking unit 5 is connected to the processing unit 3. The chain bucket reclaiming unit 2 is suspended on the outside of the housing and is fixedly connected to the housing via the base of the drive shaft system 223. A dedicated lifting mechanism (not shown in the figure) is located at the lower part of the chain bucket reclaiming unit 2 to adjust the height of the chain bucket. The chain bucket reclaiming unit 2 primarily uses the chain bucket to collect construction solid waste from the site and transports it to the top via the chain bucket system 22. The waste is then conveyed to the jaw crusher in the processing unit 3 via the conveyor port 216. The external conveying unit 4 is located at the rear of the housing (behind the chain bucket reclaiming unit 2) and is responsible for conveying the processed construction aggregate to external transport vehicles via a conveying mechanism.

[0031] Specifically, the driving power unit 1 consists of a driver's cab 11, a switchboard 12, a generator set 13, and a hydraulic pump station 14, etc. The switchboard 12, generator set, and hydraulic pump station 14 are all installed in the driver's cab 11. The construction solid waste treatment station is controlled by a PLC. The PLC control equipment is installed in the switchboard 12. The generator set 13 mainly supplies power to the hydraulic pump station 14 and the equipment. The hydraulic pump station 14 provides hydraulic power to all parts of the construction solid waste treatment station.

[0032] In addition to power distribution equipment, the distribution board 12 also contains a control cabinet. The control cabinet is used to control all the equipment in the processing station, receive and process feedback signals from all sensors, and issue control commands. Each sensor feeds back system data to the control box in the driver's cab, enabling automatic control of the device, real-time monitoring of equipment operating status, and fault alarm and remote operation and maintenance.

[0033] The control cabinet in the distribution board 12 implements a standardized control mode; different building solid waste treatment modes are selected according to the solid waste generated by different building types, such as concrete structures, steel structures, brick structures, brick-concrete structures, and wood structures.

[0034] Specifically, the chain bucket material handling unit 2 is mainly responsible for handling construction solid waste. Located at the front of the entire machine, the chain bucket material handling unit 2 consists of a protective cover 21, a chain bucket system 22, and a support structure 23. The support structure 23 is made of steel plate and is fitted onto the chain bucket system 22 to support it. The support structure 23 is connected to the housing of the construction solid waste treatment station. The protective cover 21 is directly fitted onto and fixed to the support structure 23, and secured with bolts. The protective cover 21 serves two purposes: enhancing the overall strength of the chain bucket material handling unit 2 and preventing dust from escaping.

[0035] The chain bucket material handling unit 2 integrates material handling and conveying (the chain bucket 2221 directly handles the material, and the chain bucket system 22 is driven by the drive shaft system 223 to directly transport the construction solid waste to the top of the chain bucket system. The falling construction solid waste falls directly into the jaw crusher 31 through the conveying port 216), realizing simultaneous material handling and external conveying.

[0036] The protective cover 21 is installed outside the chain bucket system 22. Specifically, the protective cover 21 consists of a protective cover shell 211, nuts 212, bolts 213, a protective cover baffle 214, fixing bolts 215, and a feed inlet 216. The protective cover 21 is a steel structure. The protective cover shell 211 and the protective cover baffle 214 are combined into a relatively closed structure by fixing bolts 215 and nuts 212, and the protective cover covers the chain bucket system. The protective cover 21 is then fixed to the supporting structure 23 by bolts 213. The feed inlet 216 is provided on the protective cover 21. The feed inlet 216 receives the construction solid waste taken by the chain bucket system 22 through the chain bucket mechanism 222, and also transports the construction solid waste to the jaw crusher 31 for crushing.

[0037] The support structure 23 is entirely made of steel plate and includes a lower positioning hole 231, a screw hole 232, a support plate 233, an upper positioning hole 234, and a tensioning mounting hole 235. All holes are located on the support plate 233. The lower positioning hole 231 and the upper positioning hole 234 are respectively fitted onto the driven shaft system 221 and the drive shaft system 223 for mounting the driven shaft system and the drive shaft system. The tensioning mounting hole 235 is used to mount the tensioning mechanism 224, and the screw hole 232 is used to mount the protective cover. The support structure 23 supports and tensions the chain bucket system 22.

[0038] Specifically, the chain bucket system 22 includes a driven shaft system 221, a chain bucket mechanism 222, a drive shaft system 223, and a tensioning mechanism (two sets of tensioning mechanisms are installed in the tensioning mounting holes 235, as shown in the figure); the drive shaft system 223 and the driven shaft system 221 provide power to the chain bucket mechanism 222, which is the material handling mechanism and is driven by the drive shaft system 223; the tensioning mechanism tensions the chain bucket mechanism 222.

[0039] The chain bucket mechanism 222 comprises a chain bucket 2221, a wear-resistant sleeve 2222, a positioning sleeve 2223, a gasket 2224, a shaft 2225, a fixing nut 2226, and an inner chain plate 2227. Multiple chain buckets 2221 are arranged sequentially to form a chain ring. The roots of the chain buckets 2221 are connected by a chain plate structure. The chain plate structure includes an inner chain plate 2227 and an outer chain plate, which are connected sequentially. The inner and outer chain plates are connected by a shaft 2225, and the end of the shaft 2225 is secured by a fixing nut 2226. A positioning sleeve 2223 is placed between two inner chain plates 2227 on the shaft 2225, and a gasket 2224 is placed between the inner and outer chain plates. A wear-resistant sleeve 2222 is placed in the connection hole between the chain plate and the shaft. The sequentially connected inner and outer chain plates connect the multiple chain buckets 2221 to form a ring.

[0040] The chain bucket 2221 includes a chain bucket body 22211 and bucket teeth 22212, with the bucket teeth 22212 integrally welded onto the chain bucket body 22211. The chain bucket body 22211 has a bucket-shaped structure, and multiple evenly distributed bucket teeth 22212 are provided on the opening edge of the chain bucket body 22211; the bucket body of the chain bucket body 2221 and the bottom outer chain plate are an integral structure.

[0041] In this embodiment, the bucket teeth are pointed structures, and the bucket teeth are evenly distributed around the opening of the chain bucket body. In addition to digging up loose construction solid waste, it can also dig up buried underground and harder blocks, such as soil and soft stones.

[0042] The drive shaft system 223 provides power to the chain bucket unloading section 2. The drive shaft system 223 includes an end cover 2231, a housing 2232, a drive roller 2233, a drive shaft 2234, a bearing 2235, a coupling 2236, a coupling 2237, a gearbox 2238, and a hydraulic motor 2239. The drive roller 2233 is mounted on the drive shaft 2234. One end of the drive shaft 2234 is provided with the housing 2232 and the end cover 2231. The drive shaft 2234 is provided with a bearing 2235 at the mating point with the housing, etc. The drive shaft 2234 is connected to the gearbox 2238 through the coupling 2236 and the coupling 2237. The gearbox 2238 is connected to the hydraulic motor 2239. The drive roller 2233 is connected to the chain plate structure of the chain bucket mechanism 222. The drive shaft system 223 is driven by the hydraulic motor 2239. The hydraulic motor 2239 drives the reduction gearbox 2238 to reduce speed, and the driving force is transmitted to the drive shaft 2234 by the coupling 2237 and coupling 2236. The drive shaft 2234 drives the drive roller 2233 to rotate, and the drive roller 2233 drives the chain bucket system to operate, thereby completing the material picking work.

[0043] The lower part of the chain bucket material handling section 2 is equipped with a dedicated lifting mechanism. This mechanism consists of a hydraulic cylinder and lugs. One end of the hydraulic cylinder is connected to the support structure of the chain bucket material handling section 2, and the other end is connected to the housing structure. By actuating the hydraulic cylinder, the height of the material handling position of the chain bucket material handling section 2 can be raised or lowered. A relative position sensor is installed between the chain bucket material handling section 2 and the housing structure to monitor the height of the chain bucket material handling section.

[0044] The processing unit 3 includes a jaw crusher 31, a blower 32, a cyclone dust collector 33, an impact crusher 34, a drum screen 35, a C1 type bucket conveyor 36, and a C2 type bucket conveyor 37. The processing unit 3 is located behind the chain bucket receiving unit 2, which collects construction solid waste and transports it to the jaw crusher 31 in the processing unit 3. The jaw crusher 31 is connected to the impact crusher 34 via the C1 type bucket conveyor 36, and the impact crusher 34 is connected to the drum screen 35 via the C2 type bucket conveyor 37. The drum screen 35 has a fine material bin 441 at its bottom. Construction solid waste is fed into jaw crusher 31 via chain bucket receiving unit 2, where it undergoes coarse crushing. The crushed material is then conveyed from the discharge port of jaw crusher 31 to the feed port of impact crusher 34 by C1 type bucket conveyor 36, where it undergoes fine crushing. The finely crushed material is then conveyed to drum screen 35 by C2 type bucket conveyor 37, where it is screened to separate standard aggregates, which are then fed into the corresponding fine material bins 441.

[0045] The fan 32 in the processing section 3 is mainly used as an air separation device to remove light materials such as paper scraps and wood chips from the crushed aggregate of the crushing plant.

[0046] The cyclone dust removal device 33 installed in the processing section 3 transports the dust generated by crushing from various equipment in the processing station to the cyclone dust removal device 33 through pipelines. The dust and particles are removed by the cyclone dust removal device 33 to meet the environmental emission requirements.

[0047] In addition to being used as conveying machinery, the C1 type bucket conveyor 36 and the C2 type bucket conveyor 37 are also equipped with magnetic separation equipment inside the conveyor to remove metal impurities from the material.

[0048] The external conveying section 4 is installed on the outside of the box structure and includes several parts: a discharge auger 41, a rotating mechanism 42, a vertical auger 43, and a retrieving auger 44. The discharge auger 41 is connected to the vertical auger 43 via the rotating mechanism 42, and the vertical auger 43 is connected to the retrieving auger 44. The rotating mechanism 42 allows the discharge auger 41 to rotate along its centerline, enabling the discharge position of the discharge auger 41 to be located on the right side or rear of the self-loading conveyor belt mobile solid waste treatment station, as needed. The retrieving auger 44 is mainly responsible for retrieving material from the concentrate bin 441. The material is lifted by the vertical auger 43, transported by the rotating mechanism 42 to the discharge auger 42, and then discharged through the discharge port 412 into a transport vehicle, which then transports it to the corresponding aggregate warehouse.

[0049] The feeding screw conveyor 44 comprises a feed chamber 441, a remote control gate valve 442, a feed inlet 443, a support structure 444, a shaft 445, screw blades 446, a housing 447, a pairing bevel gear 448, and a shell 449. The bottom of the feed chamber 441 is equipped with a remote control gate valve 442, which controls the opening of the corresponding feed chamber 441, thus controlling the output aggregate specifications. A screw conveyor mechanism is located below the feed chamber 441, with a feed inlet 443 at its top connected to the remote control gate valve 442 at the bottom of the corresponding feed chamber 441. The end of the screw conveyor mechanism is supported by the support structure 444. The screw conveyor mechanism includes a shaft 445, with screw blades 446 mounted on the shaft. The screw blades 446 are housed within the housing 447, and the aggregate is conveyed by the shaft 445 through the screw blades 446.

[0050] The material handling auger 44 and the vertical auger 43 are connected by a pair of bevel gears 448 to achieve steering and conveying. The pair of bevel gears 448 are placed in the housing 449.

[0051] The vertical spiral auger 43 consists of a housing 431, spiral blades 432, a spiral shaft 433, and a connecting flange 434. The working principle of the vertical spiral auger 43 is the same as that of the material handling spiral auger 44. The spiral shaft 433 is equipped with spiral blades 432, which are placed in the housing 431. The bottom of the housing 431 is fixedly connected to the housing 449 through the connecting flange 434.

[0052] The rotating mechanism 42 consists of a rotary motor 421, a reduction gearbox 422, and a slewing mechanism 423. The rotary motor 421 drives the slewing mechanism 423 to rotate via the reduction gearbox 422, thereby driving the discharge auger 41 to rotate. The slewing mechanism allows the discharge auger to be rotated according to the position of the construction solid waste aggregate receiving vehicle. For example, when the receiving vehicle is at the rear of the processing station, the slewing mechanism rotates the discharge auger to the rear, positioning the discharge port 412 above the receiving vehicle's hopper.

[0053] The discharge auger 41 comprises a support bearing 411, a discharge port 412, a auger shaft assembly 413, a housing 414, a bevel gear train 415, a connecting flange 416, a bevel gear train housing 417, and a drive motor 418. The auger shaft assembly 413 is housed within the housing 414. One end of the auger shaft assembly 413 is supported by the support bearing 411, and the other end is connected to the bevel gear train 415. The bevel gear train 415 is installed within a rotating mechanism, horizontally connected to the auger shaft assembly 413 of the discharge auger 41, and vertically connected to the shaft of the drive motor 418 and the auger shaft 433 of the vertical auger 43. The bevel gear train 415 is housed within the bevel gear train housing 417, and the housing 414 and the bevel gear train housing 417 are connected by the connecting flange 416. A discharge port 412 is located at the bottom of the housing 414 for material discharge.

[0054] The drive shafts of the spiral blades inside the three spiral augers 44 (feeding), 43 (vertical), and 41 (discharging) are all connected to each other by bevel gears.

[0055] The aggregate bin 441 is used to store the aggregates that have been screened. The aggregate bin 441 is equipped with material position sensors, including a high-level sensor and a high-high-level sensor. When the material height reaches the high level, the high-level sensor sends a signal to the control system, which then controls the output unit 4 to work. By opening the corresponding remote control gate valve 442, the aggregates are output through the feeding screw auger 44, the vertical screw auger 43, the rotating mechanism 42, and the discharge screw auger 41.

[0056] The traveling unit 5 comprises a tracked traveling mechanism 51, a frame structure 52, an upper platform 53, a safety chain 54, a lifting cylinder 55, and a twist lock 56. The lifting cylinder 55 and safety chain 54 are installed between the upper platform 53 and the frame structure 52, allowing relative vertical movement between them. When the construction waste treatment station encounters uneven road surfaces or pits during its movement, the lifting cylinder 55 can be used to adjust the structure, ensuring it remains level. The frame structure 52 is connected to the tracked traveling mechanism 51. The aforementioned driving power unit 1, processing unit 3, and external transport unit 4 are located on the top of the upper platform 53. A twist lock 56 is installed on the upper platform 53 for securing the traveling unit 5 to the box structure. The twist lock is a conical lock head with a twist handle that can be inserted into a hole in the corner piece at the bottom of the box structure, thus firmly locking the box structure to the upper platform 53 of the traveling unit 5.

[0057] The working process of the chain bucket self-loading tracked mobile construction solid waste treatment station of the present invention is briefly described as follows: After transporting each module of the treatment station to the construction solid waste treatment site and assembling the system, and after the system test is normal, start the generator set 13 of the driving power unit 1, start the hydraulic pump station 14, and the PLC control equipment of the power distribution board 12 is in working condition. The processing station moves forward using the tracked walking mechanism 51 of the processing station walking part 5 until the chain bucket material collection part 2 can collect the material, and the processing station moves forward slowly. Driven by the hydraulic motor 2239, the drive shaft system 223 of the chain bucket material handling unit 2 operates normally. The height of the chain bucket material handling unit is adjusted to the normal material handling position by the lifting and adjusting mechanism, and the material handling begins. The material taken up by the chain bucket 2221 is raised to the highest position by the chain bucket system 22 and then begins to be discharged. The discharged material is received by the conveying port 216 and slid through the conveying port 216 to the inlet of the jaw crusher 31. After the material enters the jaw crusher 31, it undergoes coarse crushing. The crushed material then enters the inlet of the C1 type bucket conveyor 36 from the outlet of the jaw crusher. The material enters the C1 type bucket conveyor 36, is lifted by the conveyor, and is transported from the conveyor outlet to the inlet of the impact crusher 34; The material entering the impact crusher 34 undergoes secondary and further crushing (fine crushing) and then enters the C2 type bucket conveyor 37 from the outlet of the impact crusher 34. The material enters the C2 type bucket conveyor 37, is lifted by the conveyor and transported from the conveyor outlet to the inlet of the drum screen 35; After the material enters the drum screen 35, the drum screen 35 screens the material. The drum screen 35 divides the material into four parts, and the four parts of aggregate that meet the requirements enter the corresponding fine material bin 441 through the corresponding channels. The aggregate in the feed bin 441 is controlled by a remote gate valve 442 and transported to external transport vehicles via the external conveying unit 4 from the feeding screw 44, vertical screw 43, rotating mechanism 42 and discharge screw 41.
