Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and more specifically, to a waste crushing residue conveyor. Background Technology

[0002] With the acceleration of urbanization and the improvement of people's living standards, the amount of urban solid waste is constantly increasing, putting enormous pressure on the environment. Waste disposal, as a crucial aspect of environmental protection, directly impacts urban sanitation and residents' quality of life. Among various waste disposal methods, crushing, as a common pretreatment method, can effectively reduce waste volume. After crushing, an efficient, reliable, and adaptable conveying mechanism must be installed to stably and continuously transfer the crushed residue to the next processing unit (such as a sorting machine, bio-fermentation chamber, or incinerator feed inlet).

[0003] However, in practical engineering applications, conveyors often need to lift materials from the crusher outlet to the incinerator feed inlet, sorting equipment inlet, or intermediate storage silo at a certain angle (usually 10°–20°) to adapt to compact plant layouts or process flow requirements. Under such inclined conveying conditions, high-moisture residue is prone to slippage, accumulation, or even blockage due to gravity, which not only reduces conveying efficiency but may also cause equipment overload and shutdown. Furthermore, the height of traditional waste crushing residue conveyors is usually fixed, and when connecting to feed or discharge equipment of different heights, additional auxiliary devices are often required for adjustment, increasing operational complexity and cost. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a waste crushing residue conveyor to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A waste crushing residue conveyor includes a support frame with two drive rollers rotatably connected to it. The drive rollers are connected to a conveyor belt, which has multiple partition plates and a cleaning mechanism at its bottom. Four support feet are hinged to the outside of the support frame, and the bottom of each support foot is connected to a hydraulic telescopic rod. The hydraulic telescopic rod is electrically connected to a PLC controller, which is also electrically connected to a tilt sensor. The tilt sensor is installed at the middle of one side of the support frame.

[0007] Furthermore, the cleaning mechanism includes a fixed frame located at the bottom of the support frame, a movable rod being connected through the fixed frame, one end of the movable rod being connected to a mounting plate, a scraper being connected to one side of the mounting plate, and a telescopic spring being sleeved on the outside of the movable rod, one end of the telescopic spring being connected to the fixed frame, and the other end being connected to the mounting plate.

[0008] Furthermore, the scraper and the separator are inclined on one side.

[0009] Furthermore, the mounting plate and the scraper are connected by the first bolt.

[0010] Furthermore, a limiting block is connected to the middle position of the mounting plate, and one end of the limiting block is connected through the fixing frame.

[0011] Furthermore, a fixed plate is connected to the conveyor belt, and a mounting groove is provided on one side of the partition plate. The fixed plate matches the mounting groove, and the fixed plate and the partition plate are connected by a second bolt.

[0012] Furthermore, the drive shaft of the drive roller is connected to the reducer, the input end of the reducer is connected to the drive motor, and the drive motor is fixed to the outside of the support frame.

[0013] Furthermore, baffles are connected to both sides of the top of the support frame.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) Four support legs are hinged to the outside of the support frame, and hydraulic telescopic rods are connected to the bottom of each support leg. A closed-loop control system is formed by a PLC controller and an inclination sensor. This design can achieve precise and automatic adjustment of the overall height and conveying inclination angle, effectively adapting to different working conditions (such as differences in inlet / outlet height, changes in material flowability, etc.), and improving the equipment's versatility and operating efficiency. Multiple partition plates are set on the conveyor belt, evenly distributed along the belt running direction, forming multiple independent material carrying units. The partition plates can effectively prevent the slippage of wet waste crushing residue during the inclined conveying process, meeting the spatial layout requirements for feeding materials to incinerators, sorting equipment, or storage silos.

[0016] (2) By setting a cleaning mechanism on the conveyor belt, the scraper is connected to the mounting plate via a moving rod and is provided with elastic preload by a telescopic spring. This structure can automatically adjust the scraper clamping force according to the thickness of the residue on the belt surface and the operating status, which not only ensures the cleaning effect, but also avoids belt scratches or scraper breakage caused by rigid contact. In addition, both the scraper and the partition plate are inclined on one side, so that the scraper can move along the inclined surface of the partition plate. The two form a smooth transition in relative movement, which not only reduces mechanical interference and impact wear, but also significantly improves the continuity and integrity of cleaning.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] According to an embodiment of the present invention, a waste crushing residue conveyor is provided.

[0028] like Figures 1-4 As shown, the waste crushing residue conveyor according to an embodiment of the present utility model includes a support frame 1, which serves as the load-bearing and installation foundation for the entire machine. Two drive rollers 2 are rotatably connected to the support frame 1. The two drive rollers 2 are tensioned together to support and drive a ring conveyor belt 3 to operate. The conveyor belt 3 adopts a high-strength wear-resistant rubber or composite fabric core structure to adapt to the sharp foreign objects that may be present in the crushed residue and the long-term wear conditions. The conveyor belt 3 is equipped with multiple partition plates 4, and a fixing plate 8 is connected to the conveyor belt 3. The partition plate 4 has an installation groove 9 on one side, and the fixing plate 8 matches the installation groove 9. The fixing plate 8 and the partition plate 4 are connected by a second bolt 10. This modular connection method facilitates the quick installation and replacement of the partition plate 4. The drive shaft of the drive roller 2 is connected to the reducer 11, and the input end of the reducer 11 is connected to the drive motor 12. This facilitates heat dissipation and maintenance, and effectively isolates the influence of garbage dust, moisture and corrosive gases on the internal components of the motor. The drive motor 12 is fixed to the outside of the support frame 1. Baffles 13 are connected to both sides of the top of the support frame 1 to prevent materials from spilling from both sides of the belt during the conveying process.

[0029] Four support legs 14 are hinged to the outer side of the support frame 1. The bottom ends of the support legs 14 are connected to hydraulic telescopic rods 15, and their extension and retraction are precisely controlled by a PLC controller 16. The PLC controller 16 is also electrically connected to a high-precision tilt sensor 17 installed in the middle of one side of the support frame 1. The tilt sensor 17 can collect the tilt angle data of the current conveyor in real time. When the operator sets the target tilt angle on the control panel of the PLC controller 16, the PLC controller 16 will automatically issue commands to adjust the extension or retraction length of the corresponding hydraulic telescopic rod 15 according to the deviation between the actual angle fed back by the tilt sensor 17 and the target value, thereby dynamically adjusting the posture of the whole machine and achieving precise and stable adjustment of height and tilt angle. This closed-loop control system not only greatly improves the equipment's adaptability to different working conditions (such as sorting machines, bio-fermentation chambers, or incinerator feed inlets), but also significantly reduces manual intervention, improves the level of automation, and enhances operational safety.

[0030] like Figures 4-6As shown, a cleaning mechanism 5 is provided at the bottom of the conveyor belt 3. The cleaning mechanism 5 includes a fixed frame 501 located at the bottom of the support frame 1. A movable rod 502 is connected through the fixed frame 501. One end of the movable rod 502 is connected to a mounting plate 503. A scraper 504 is connected to one side of the mounting plate 503. A telescopic spring 505 is sleeved on the outside of the movable rod 502. One end of the telescopic spring 505 is connected to the fixed frame 501, and the other end is connected to the mounting plate 503. The scraper 504 is inclined to one side of the partition plate 4. When the conveyor belt 3 runs to the return section, the scraper 504 can slide smoothly along the inclined surface of the partition plate 4. It can remove residual debris adhering to the surface of the belt and the surface of the separator plate 4. The mounting plate 503 and the scraper 504 are connected by the first bolt 6, which makes it easy to replace them individually according to the wear condition without disassembling the entire cleaning mechanism 5. A limit block 7 is connected in the middle of the mounting plate 503. One end of the limit block 7 is connected through the fixed frame 501 to limit the vertical displacement of the mounting plate 503, ensuring that the scraper 504 is stable and evenly stressed during operation, and avoiding swaying or failure due to vibration or impact. The bottom of the support frame 1 is provided with a collection trough (not shown in the figure) for collecting the scraped residue.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] Before starting, the operator can set the target tilt angle through the PLC controller 16. The PLC controller 16 will automatically adjust the length of the hydraulic telescopic rod 15 based on the data fed back by the tilt angle sensor 17 to ensure that the whole machine is in the optimal working posture to adapt to different working environments or the height requirements of docking equipment. Then, after the drive motor 12 starts, the power is transmitted to the drive roller 2 through the reducer 11, which drives the conveyor belt 3 to circulate along the support frame 1. The waste crushing residue falls from the feed end into the material chamber formed by the adjacent partition plates 4 and is conveyed upwards segment by segment as the belt runs. Due to the presence of the partition plates 4, even under inclined conditions, wet and sticky residue is not easy to slide down, effectively ensuring the conveying efficiency and stability. During the conveying process, some fine crushed materials, leachate, or sticky organic matter may adhere to the surface of the conveyor belt 3 or accumulate on the surface of the partition plates 4. When the belt reaches the return section (i.e., the bottom), the cleaning mechanism 5 begins to function: the scraper 504, under the elastic preload of the telescopic spring 505, remains in contact with the lower surface of the belt; simultaneously, due to its matching inclined structure on the same side as the separator plate 4, when the separator plate 4 moves to the scraper 504, the scraper 504 can slide along the inclined surface of the separator plate 4, simultaneously scraping away debris and dirt remaining on the belt base and the back of the separator plate 4. The scraped residue naturally falls into the lower collection trough or is directly discharged into the sewage channel, avoiding secondary pollution. When the scraper 504 wears out due to long-term use, it can be quickly replaced simply by loosening the first bolt 6, without disassembling the entire cleaning mechanism 5 or the conveyor belt 3.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
