Description

Technical Field

[0001] This utility model relates to the field of coal-water separation equipment technology, specifically a feeding component for coal-water separation. Background Technology

[0002] As a vital energy resource, coal mine safety has always been a key concern in my country. Coal mine drainage ditches are an essential component of coal mine production, responsible for drainage and preventing water accumulation to ensure mine safety. During coal mining, large amounts of wastewater and rainwater are generated, carrying silt, coal dust, and other impurities into the drainage ditches. Over time, these impurities gradually accumulate at the bottom of the ditches, forming silt. Silt buildup not only affects drainage efficiency but can also cause blockages, thus impacting normal coal mine production and safety. Therefore, regular cleaning of drainage ditches is necessary to ensure normal coal mine production and safety. However, traditional manual cleaning methods are inefficient, risky, and incomplete, easily leading to ditch blockages and disrupting normal mine operations. Utility Model Content

[0003] To address the problems of low efficiency, high risk, and incomplete cleaning, which can easily lead to clogging of the drainage ditch, the present invention provides a feeding assembly for coal-water separation.

[0004] The technical solution of this utility model is as follows: A feeding assembly for coal-water separation includes a movable ditch cleaning machine platform. A main lifting device is vertically installed on one side of the ditch cleaning machine platform. A protective base plate is rotatably installed above the main lifting device. Support plates are installed on both sides of the protective base plate, perpendicular to it and perpendicular to the direction away from the ditch cleaning machine platform. A transmission assembly is also installed between adjacent support plates. The main lifting device has an auxiliary lifting device rotatably mounted on the side of the main lifting device that is away from the connection position with the protective base plate and close to the protective base plate, and the end of the auxiliary lifting device that is away from the main lifting device is rotatably connected to the protective base plate. The lifting of either the main lifting device or the auxiliary lifting device can drive the protective base plate to rotate in its vertical plane and change the relative height of the two ends.

[0005] In order to fix the main lifting device to one side of the ditch cleaning machine platform and enhance the stability of the main lifting device, the main lifting device and the ditch cleaning machine platform are connected at multiple points by reinforcing rods, and the connected reinforcing rods are parallel to each other in the vertical direction of the reinforcing rods.

[0006] Furthermore, in the feeding assembly for coal-water separation described above, the transmission assembly includes transmission rollers disposed at both ends of a protective base plate and a transmission chain rotating on the surface of the transmission rollers, wherein both ends of the transmission rollers are rotatably connected to adjacent support plates.

[0007] To improve transmission efficiency, a fastening device is provided on the outer surface above the support plate. One end of the fastening device is fixed to the surface of the support plate, and the other end is connected to both ends of the transmission roller located on the outside of the support plate.

[0008] As a preferred technical solution, the surface of the transmission chain is also uniformly provided with multiple material hoppers, which are detachable from the transmission chain.

[0009] To improve the applicability of the feeding assembly, there is a certain angle between the protective base plate and the horizontal plane of the ditch cleaning machine platform. The main lifting device and the auxiliary lifting device drive the protective base plate to have an angle range of 50-70° with the horizontal plane of the ditch cleaning machine platform.

[0010] To facilitate the feeding device's ability to reach deep into the drainage ditch to retrieve materials, the length of the protective base plate is shorter than the length of the support plate.

[0011] Furthermore, the feeding assembly for coal-water separation described above also includes a receiving hopper, which is disposed below the support plate at one end of the mounting and fastening device.

[0012] As a preferred technical solution, a buffer pad is provided at the end of the material hopper away from the transmission chain. The end of the buffer pad that is not in contact with the material hopper is serrated, and the material of the buffer pad is one of rubber, polypropylene plastic or polyvinyl chloride plastic.

[0013] To enhance the stability between adjacent support plates, multiple reinforcing plates are also provided between adjacent support plates, specifically at the end away from the protective base plate.

[0014] The beneficial effects of this utility model are as follows: This invention employs a dual-adjustment structure with a main lifting device and an auxiliary lifting device, and utilizes a rotating base to achieve multi-angle flexible deflection of the protective base plate. This allows the entire feeding assembly to precisely adapt to coal mine ditch cleaning environments of varying depths and angles, greatly improving the equipment's adaptability and positioning accuracy. The transmission assembly uses a transmission chain to drive a detachable material hopper for cyclical feeding, effectively achieving continuous and efficient lifting and transfer of sludge, coal dust, and other debris, significantly improving the automation level and work efficiency of ditch cleaning. Simultaneously, the detachable design of the material hopper facilitates maintenance and replacement, reducing the long-term operating costs of the equipment.

[0015] Furthermore, this utility model effectively improves the connection rigidity and overall stability between the feeding assembly and the ditch clearing machine platform, as well as between the support plates, by incorporating reinforcing rods and plates. The fastening device on the outer side of the support plate cooperates with the receiving hopper below to ensure the tension of the transmission chain and the smooth collection and transfer of materials, preventing material spillage. The serrated buffer pad at the end of the material hopper effectively reduces impact wear between the hopper and the trench bottom during digging, extending the service life of key components.

Detailed Implementation

[0019] Example like Figure 1-4 The feeding assembly shown is for coal-water separation and aims to solve the problems of low efficiency, high risk, incomplete cleaning, and easy blockage of ditches caused by traditional manual cleaning of silt in coal mine ditches. This embodiment provides a feeding assembly for coal-water separation, including a ditch cleaning machine platform 1 that can move along the ditch. A main lifting device 2 is installed on one side of the ditch cleaning machine platform 1. In this embodiment, the main lifting device 2 is a multi-stage hydraulic cylinder to provide sufficient lifting force and stable stroke. To improve the connection stability between the main lifting device 2 and the ditch cleaning machine platform 1, the two are fixedly connected by reinforcing rods. In this embodiment, two sets of reinforcing rods are provided, parallel to each other along the vertical direction of the main lifting device 2, and fixedly connected to the lower end and middle of the main lifting device 2, respectively. A protective base plate 3 is rotatably mounted on the piston rod of the main lifting device 2 via a rotating base. The protective base plate 3 can rotate relative to the main lifting device 2 in a vertical plane. To improve the conveying capacity of the feeding assembly, the protective base plate 3 is rectangular in shape when viewed from above, and is curved on one side, meaning that both ends of the protective base plate 3 are vertical and the middle is inclined. Support plates 4 are provided on both sides of the protective base plate 3, near and away from the ditch cleaning machine platform 1, perpendicular to it and perpendicular to the direction away from the ditch cleaning machine platform 1. Adjacent support plates 4 are parallel to each other. It is worth noting that, to prevent the protective base and support plates 4 from having the same length and affecting material collection, the length of the protective base is shorter than the length of the support plates 4.

[0020] To achieve precise and flexible adjustment of the tilt angle of the protective base plate 3, an auxiliary lifting device 5 is installed at the end of the main lifting device 2 away from the connection point with the protective base plate 3. The auxiliary lifting device 5 is also a hydraulic cylinder, positioned on the side of the main lifting device 2 closest to the protective base plate 3. The other end of the auxiliary lifting device 5 is connected to the center of the bottom surface of the protective base plate 3 via a rotating base. Thus, the main lifting device 2, the auxiliary lifting device 5, and the protective base plate 3 together form a stable triangular linkage mechanism. By controlling the extension and retraction strokes of the main lifting device 2 and the auxiliary lifting device 5, this equipment can drive the protective base plate 3 to rotate around its connection point with the top of the main lifting device 2, thereby flexibly changing the relative height between its unloading end and its feeding end, allowing it to adapt to different angle adjustments.

[0021] In addition, the lifting of either the main lifting device 2 or the auxiliary lifting device 5 can drive the protective base plate 3 to rotate in its vertical plane and change the relative height of the two ends. That is, when the main lifting device 2 lifts, it can drive the protective base plate 3 to rotate around the auxiliary lifting device 5, and the lifting of the auxiliary lifting device 5 can drive the protective base plate 3 to rotate around the main lifting device 2, so as to achieve an adjustment range of 50-70° between the protective base plate 3 and the horizontal plane of the ditch cleaning machine platform 1. When dealing with shallow ditches, the angle between the protective base plate 3 and the horizontal plane of the ditch cleaning machine platform 1 is smaller, and when dealing with deep ditches, the angle between the protective base plate 3 and the horizontal plane of the ditch cleaning machine platform 1 is larger.

[0022] To achieve power transmission and material lifting, a transmission assembly 6 is installed between the parallel support plates 4. The transmission assembly 6 includes transmission rollers 61 located at both ends of the protective base, and a transmission chain 62 tensioned on the surfaces of the two transmission rollers 61. The two ends of the transmission rollers 61 are rotatably connected to the two sides of the support plates 4 via bearings. The transmission roller 61 located at the higher end of the support plate 4 is driven by a drive motor (not shown in the figure) installed between the support plate 4 and the ditch cleaning machine platform 1 via a chain or belt. To prevent the transmission rollers 61 from axially shifting during high-speed operation, a fastening device 8 is installed on the outer surface above the support plate 4. One end of the fastening device 8 is fixed to the outer surface of the support plate 4 by welding, and the other end is connected to the two ends of the transmission rollers 61 located on the outer side of the support plate 4.

[0023] To better collect materials from inside the ditch, multiple material hoppers 7 are detachably mounted on the outer surface of the drive chain 62. In this embodiment, the drive chain 62 and the material hoppers 7 are fixed together by bolts. When the material hoppers 7 are worn or damaged, they can be disassembled and replaced individually, reducing maintenance costs. The multiple material hoppers 7 are evenly distributed on the surface of the drive chain 62. The material hoppers 7 are integrally molded and have an overall trapezoidal structure. Furthermore, at the leading edge of the opening of each material hopper 7 away from the drive chain 62, a buffer pad 10 is firmly bonded using a high-strength adhesive. The buffer pad 10 is made of rubber, polypropylene plastic, or polyvinyl chloride plastic. In this embodiment, the buffer pad 10 is made of polypropylene plastic, which has excellent elasticity, wear resistance, and corrosion resistance.

[0024] To further enhance the deformation resistance of the support plate 4, multiple reinforcing plates are provided on the side of the adjacent support plate 4 away from the protective base plate 3. In this embodiment, two sets of reinforcing plates are provided on both ends of the support plate 4. The reinforcing plates are vertically welded to the support plate 4 to form a frame structure, which can effectively disperse the lateral vibration generated by the transmission component 6 during operation and prevent the support plate 4 from bending and deforming due to long-term stress.

[0025] In order to better collect materials from the residential area, a receiving hopper 9 is installed below the unloading end of the protective base plate 3 to receive materials thrown out from the material hopper 7 and to introduce the materials into the subsequent processing equipment in a non-destructive and centralized manner.

[0026] Please refer to the appendix. Figure 1-4When using this device, the ditch cleaning machine platform 1 is first moved to the side of the ditch to be cleaned. According to the depth of the ditch, the tilt angle of the protective base plate 3 is adjusted by the main lifting device 2 and the auxiliary lifting device 5. The drive motor of the transmission component 6 is started, which drives the transmission roller 61 and the transmission chain 62 to move clockwise in a circular motion. The material hopper 7 moves down to the bottom of the ditch with the transmission chain 62, grabs the silt through the sawtooth structure of the buffer pad 10, and then moves up to the top of the protective base plate 3 with the transmission chain 62. When the material hopper 7 moves to the top of the transmission chain 62, the silt is poured into the receiving hopper 9 below under the action of gravity. Finally, it is transported to the external collection equipment through the lower opening of the receiving hopper 9, completing the silt transportation cycle.
