[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] Example 1: Please refer to Figure 1 , 4 5. One embodiment of this utility model: A novel environmentally friendly belt cleaning device, installed at the bottom of a belt conveyor, includes a housing 1, a scissor-type lifting device 2, a top cover 3, an air knife 4, a cleaning roller 5, a lower clamping roller 6, and an upper clamping roller 9.

[0028] The housing 1 is a rectangular, hollow shell with an upward-facing opening, located at the bottom of the belt conveyor. As the external frame of the entire cleaning device, housing 1 supports and secures all other components. Its rectangular, upward-facing hollow structure ensures a tight fit between the device and the bottom of the belt conveyor, protecting internal components from external environmental influences. It also provides a structurally stable support platform and forms a relatively sealed space with the top cover 3, preventing dust from flying during internal cleaning. Vertical extensions are provided on both the left and right sides of housing 1, with the distance between these extensions greater than the width of the belt. The top of the extension extends beyond the bottom of the belt fold and is located in the middle of the belt return end. The extension forms a concave groove with the housing 1, providing space for the belt to pass through. Simultaneously, the top of the extension connects to the top cover 3, forming a relatively sealed space. The top cover 3 helps prevent dust and debris from overflowing from the top of the cleaning device, ensuring effective maintenance of the entire system's cleaning function. Furthermore, a space is formed between the extension, housing 1, and top cover 3 for the belt return end to pass through. The left and right sides of the extension are symmetrically equipped with sliding grooves, located at the front and rear ends of the housing 1, respectively.

[0029] Slider 7 is installed in the chute, and a lower clamping roller 6 is connected between the left and right sliders 7. In the initial position, the central axis of the lower clamping roller 6 is flush with the top of the housing 1, and the outer circumference of the lower clamping roller 6 abuts against the outer circumference of the upper clamping roller 9. A groove is provided in the housing 1 at the position of the lower clamping roller 6 to accommodate it. The lower clamping roller 6 cooperates with the upper clamping roller 9 to clamp and guide the belt at the return end of the belt, while reducing friction between the belt and the top cover 3 and the housing 1. Grooves are provided in both the housing 1 at the position of the lower clamping roller 6 and the top cover 3 at the position of the upper clamping roller 9. The lower clamping roller 6 and the upper clamping roller 9 are accommodated in the grooves, and their outer circumferences abut against the belt. Both the lower clamping roller 6 and the upper clamping roller 9 are made of rubber. When in contact with the belt, the extended portion forms a concave groove with the housing 1 for sealing, creating a sealed space between the housing 1 and the top cover 3. This prevents dust overflow when the air knife 4 and cleaning roller 5 are working, and simultaneously cooperates with the upper clamping roller 9. The lower clamping roller 6 is slidably fitted onto the housing 1. A spring 8 is provided between the bottom end of the slider 7 and the groove. The spring 8 supports the slider 7 and the lower clamping roller 6 and allows for fine adjustment. Through the cooperation of the spring 8 and the slider 7, belts of different thicknesses can pass through the gap between the lower clamping roller 6 and the upper clamping roller 9. During installation, the lower clamping roller 6 is installed at the bottom end of the belt, and the top cover 3 is then installed. The upper clamping roller 9 squeezes the belt and the lower clamping roller 6, simultaneously moving the slider 7 and squeezing the spring 8. When the device is removed, spring 8 drives slider 7 to reset, simultaneously driving lower clamping roller 6 to reset. One end of spring 8 abuts against the slide groove, and the other end abuts against the bottom end of slider 7. The bottom end of top cover 3 is connected to upper clamping roller 9 corresponding to the position of lower clamping roller 6. Lower clamping roller 6 and upper clamping roller 9 are made of rubber. The outer circumferences of lower clamping roller 6 and upper clamping roller 9 abut against the belt. Simultaneously, the distance between lower clamping roller 6, upper clamping roller 9 and the corresponding end face of the extension is the same. The front and rear ends of the housing 1 are symmetrically connected to air knives 4. Airflow is provided through air knives 4 to help clean the surface of the belt, removing dust or debris. It can effectively remove minor dirt and impurities from the belt. It is used in conjunction with cleaning roller 5, and the air outlet is angled. When the belt is running, the air outlet blows air out at an angle to the belt, effectively cleaning the deposits on the belt. The air knife 4 is angled, with its air outlet aligned with the belt. A cleaning roller 5 is located between the front and rear air knives 4. The cleaning roller 5 is equipped with a brush for mechanically cleaning the belt surface. The brush can effectively remove dust, dirt, and other substances accumulated on the belt surface, ensuring that the belt is always clean and thus extending its service life. At the same time, the top of the cleaning roller 5 is flush with the central axis of the extension section, making it easy to clean the deposits on the belt. Simultaneously, when the belt is running, it drives the cleaning roller 5 to roll, cleaning the belt. It is connected to the middle of the housing 1, and its outer circumference abuts against the belt. Several brushes are provided on the outer circumference of the cleaning roller 5, and the brushes abut against the belt.Bearing seats are connected to the contact ends of the lower clamping roller 6 and the slider 7, the contact end of the cleaning roller 5 and the housing 1, and the contact end of the upper clamping roller 9 and the top cover 3. The bearing seats are used to reduce friction during rotation and provide support and positioning. The housing 1 has an air knife inlet at the position of the air knife 4. The air knife inlet is connected to the air source through the air inlet pipe 10. A solenoid valve is connected to the pipe. The air knife inlet is connected to the air source through the air inlet pipe 10 to provide compressed air. The compressed air blows the belt through the air outlet. The cleaning process includes removing surface deposits and includes a dust collection port located at the bottom of the housing 1. The dust collection port is connected to a dust collector via a dust collection pipe 11, which is equipped with a one-way valve. This system collects dust and debris generated during the cleaning process, effectively cleaning the housing 1, maintaining a clean working environment, and minimizing impact on the equipment. Simultaneously, the one-way valve prevents dust and debris from entering the housing 1.

[0030] During installation, the lower clamping roller 6 is installed at the bottom of the belt, and the top cover 3 is installed subsequently. The upper clamping roller 9 squeezes the belt and the lower clamping roller 6, while simultaneously driving the slider 7 to move and squeezing the spring 8. At the same time, the upper clamping roller 9 and the lower clamping roller 6 are accommodated in the groove, forming a sealed space between the housing 1 and the top cover 3. The bottom end of the belt abuts against the outer circumference of the cleaning roller 5. Then, the air knife 4 is activated, and the air outlet of the air knife 4 blows air onto the belt. At the same time, when the belt is running, it drives the cleaning roller 5 to rotate. The brush on the surface of the cleaning roller 5 cleans the surface of the belt. Then, the dust is adsorbed by the dust collector and enters the dust collector through the dust collection pipe 11.

[0031] Example 2: Please refer to Figure 1-3 Based on Example 1, it also has the following structure:

[0032] The system also includes a scissor lift device 2, comprising a base 201, an outer scissor lift 202, an inner scissor lift 203, and a lifting plate 204. The base 201 and lifting plate 204 are rectangular frames. The base 201 is the supporting structure for the entire device, providing stable support and a base for other components. The base 201 bears the load of the entire device and ensures stable operation. Its bottom end contacts the ground for support. The lifting plate 204 is connected to the bottom end of the housing 1. Guide grooves are symmetrically provided on both sides of the frame. The outer scissor lift 202 and inner scissor lift 203 are a pair of spaced-apart lifting rods. The inner scissor lift 203 is located inside the outer scissor lift 202. The outer scissor lift 202 and inner scissor lift 203 work together. When the piston rod of the hydraulic cylinder 207 extends, it drives the inner scissor lift 203 to adjust its angle. Simultaneously, the rollers slide within the guide grooves, causing the lifting plate 204 to rise and the outer scissor lift 202 to shift. The housing 1 is lifted, and the inner shear 203 is hinged to the middle of the outer shear 202. A crossbar 206 connects the two inner shears 203, serving to connect the inner shears 203 and also connecting to the hydraulic cylinder 207. It is located in the upper middle part of the two inner shears 203. The bottom end of the outer shear 202 is hinged to one side of the lifting plate 204, and the top end is connected by a connecting rod 205, which passes through the outer shear 202. Rollers are connected to both sides of the connecting rod, which slides in guide grooves. The top end of the inner shear 203 is hinged to one side of the base 201, and the top end is connected by a connecting rod 205, which passes through the inner shear 203. Rollers are connected to both sides of the connecting rod, which slides in guide grooves. The hydraulic cylinder 207 is hinged to the base 201 and connected to a hydraulic pump through a pipeline. A regulating valve is connected to the pipeline, and the top end of its piston rod is hinged to the crossbar 206.

[0033] When it is necessary to handle belt clamping and cleaning at different heights, the hydraulic cylinder 207 is activated. The piston rod of the hydraulic cylinder 207 drives the crossbar 206 to move, and at the same time drives the inner shear 203 to shift. The hydraulic cylinder 207 shifts synchronously, and the roller slides in the guide groove, which synchronously drives the lifting plate 204 to rise. At the same time, the roller of the outer shear 202 slides in the guide groove, which synchronously drives the outer shear 202 to shift, lifting the lifting plate 204, increasing stability, and completing the lifting adjustment of the housing 1, so that the concave groove between the housing 1 and the extension is located at the bottom end of the belt.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
