Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and more specifically, to an antifreeze and anti-stick belt conveyor. Background Technology

[0002] In open-pit coal mining, belt conveyors are crucial material transport equipment. However, in cold winters, materials such as coal are prone to freezing and sticking to the feed chute and conveyor belt, leading to increased belt resistance, material spillage, and reduced transport efficiency. This also increases equipment wear and maintenance costs.

[0003] Therefore, how to provide a belt conveyor that can effectively prevent materials from freezing and adhering is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an antifreeze and anti-stick belt conveyor, which can effectively prevent materials from freezing and sticking to the guide chute and conveyor belt in low-temperature environments, thereby improving the operational stability and conveying efficiency of the belt conveyor in low-temperature environments.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A freeze-proof and anti-stick belt conveyor, comprising:

[0007] Conveyor rack;

[0008] A conveyor belt is mounted on the conveyor frame and connected to a drive device for driving the conveyor belt to rotate around the conveyor frame. The conveyor belt is an antifreeze adhesive conveyor belt made of several layers of thin film material.

[0009] A guide trough is located above the feed end of the conveyor belt with its discharge port facing the bearing surface of the conveyor belt. The outer wall of the guide trough is provided with a heating film, and the interior of the guide trough is provided with a temperature sensor. Both the heating film and the temperature sensor are signal-connected to a controller. The controller is used to receive the temperature signal from the temperature sensor and control the heating film to heat up when the temperature is lower than a preset temperature.

[0010] An ultrasonic cleaner is located below the discharge end of the conveyor belt and close to the return surface of the conveyor belt.

[0011] Preferably, the conveyor belt includes an anti-stick surface layer and a cold-resistant elastic layer arranged sequentially along the direction from the top surface to the bottom surface of the conveyor belt.

[0012] Preferably, the conveyor belt further includes a heat insulation layer, a tensile layer, and an antifreeze layer arranged sequentially on the side of the cold-resistant elastic layer facing away from the anti-stick surface layer.

[0013] Preferably, the heating film is uniformly applied to the outer wall of the feed trough using an adhesive.

[0014] Preferably, the heating film is composed of several wall films evenly arranged around the outer peripheral wall of the feed channel;

[0015] The temperature sensors are configured as a plurality of those evenly arranged around the inner peripheral wall of the feed trough, and each temperature sensor is linked to at least one of the wall membranes.

[0016] Preferably, the signal lead of the temperature sensor is led out of the material guide trough through a waterproof sealing joint.

[0017] Preferably, the power line connecting the heating film to the power source and the signal line connecting the heating film to the controller are both wrapped with insulating sleeves.

[0018] Preferably, the ultrasonic cleaner includes a housing, an ultrasonic power supply, and a plurality of ultrasonic transducers. The housing is fixed on the conveyor frame and a predetermined distance is left between its top end and the return surface of the conveyor belt. The ultrasonic power supply is located inside the housing on the side away from its top end. The plurality of ultrasonic transducers are spaced apart at the top end inside the housing and are all electrically connected to the ultrasonic power supply.

[0019] Preferably, the device further includes a funnel, the interior of which is inserted into the discharge end of the conveyor belt. The funnel is equipped with at least one cleaner, which is located below the turning point of the discharge end of the conveyor belt and has an elastic scraper that contacts the conveyor belt. Along the conveying direction of the conveyor belt, the cleaner is located behind the ultrasonic cleaner.

[0020] Preferably, the driving device includes a feed end roller, a discharge end roller, a motor, and several idler rollers;

[0021] Some of the rollers are evenly arranged on the upper end face of the conveyor frame, and another part of the rollers are evenly arranged on the lower end face of the conveyor frame, leaving a space in the horizontal direction between them and the funnel. The ultrasonic cleaner is installed in the space.

[0022] The feed end roller and the discharge end roller are rotatably mounted at both ends of the conveyor frame. The motor drives and connects to the discharge end roller. The conveyor belt connects the feed end roller and the discharge end roller and rotates around several idler rollers.

[0023] The antifreeze and anti-stick conveyor belt provided by this utility model uses a temperature sensor to monitor the internal temperature of the guide trough in real time during operation and transmits the data to the controller. When the temperature is lower than a preset temperature threshold, it indicates that the internal temperature of the guide trough is too low and adhesion may occur. The controller then activates a heating film to heat the guide trough, effectively maintaining the internal temperature within a suitable range and preventing materials from freezing and sticking to it, thus ensuring that the materials fall smoothly onto the conveyor belt for transport. Furthermore, during conveyor belt operation, the antifreeze and anti-stick conveyor belt, composed of several layers of thin film material, enhances its antifreeze and anti-stick properties, reducing the risk of materials freezing and sticking to the belt, decreasing wear and resistance in the load-bearing section, and thus improving the stability and efficiency of the conveyor belt operation. In addition, even if some material remains frozen on the conveyor belt after unloading, the ultrasonic cleaner can use high-frequency vibration to clean the frozen material on the conveyor belt during the initial stage of the conveyor belt's return run. This prevents the material from freezing and sticking to the conveyor belt, reduces wear and resistance on the return section of the conveyor belt, and thus improves the stability and conveying efficiency of the conveyor belt operation.

[0024] Therefore, the antifreeze and anti-stick belt conveyor provided by this utility model, through the combined action of the antifreeze and anti-stick guide chute, the antifreeze and anti-stick conveyor belt and the ultrasonic cleaner, can effectively prevent materials from freezing and sticking to the guide chute and conveyor belt in low-temperature environments, thereby improving the operational stability and conveying efficiency of the belt conveyor in low-temperature environments.

[0037] 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.

[0038] The core of this utility model is to provide an antifreeze and anti-stick belt conveyor. This antifreeze and anti-stick belt conveyor can effectively prevent materials from freezing and sticking to the guide chute and conveyor belt in low-temperature environments, thereby improving the operational stability and conveying efficiency of the belt conveyor in low-temperature environments.

[0039] It should be noted that in this embodiment, the orientation or positional relationship indicated by "up", "down", "front", "back", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on this application.

[0040] Please refer to Figure 1 This application provides an antifreeze and anti-stick belt conveyor, including a conveyor frame 1, a conveyor belt 2, a guide trough 3, and an ultrasonic cleaner 4.

[0041] The conveyor belt 2 is mounted on the conveyor frame 1 and connected to a drive device for driving the conveyor belt 2 to rotate around the conveyor frame 1. The conveyor belt 2 is an antifreeze adhesive conveyor belt 2 made of several layers of thin film material.

[0042] It should be noted that the conveyor belt 2 can be composed of different film materials (such as Teflon coating or polyethylene film, neoprene rubber) to form a conveyor belt 2 with anti-freeze and anti-stick properties, thereby preventing materials from freezing and sticking to the conveyor belt 2, reducing wear and resistance in the load-bearing section of the conveyor belt 2 (which refers to the part of the conveyor belt 2 that carries and transports materials), and thus improving the stability and conveying efficiency of the conveyor belt 2.

[0043] The guide trough 3 is located above the feed end of the conveyor belt 2 and its discharge port faces the bearing surface of the conveyor belt 2. The outer wall of the guide trough 3 is provided with a heating film 31 and the interior of the guide trough 3 is provided with a temperature sensor 32. The heating film 31 and the temperature sensor 32 are both connected to the controller. The controller is used to receive the temperature signal of the temperature sensor 32 and control the heating film 31 to heat when it is lower than the preset temperature.

[0044] It should be noted that the guide chute 3 is mainly used to guide the material to fall onto the conveyor belt 2 in a concentrated manner, preventing the material from spilling out. The guide chute 3 is set above the feed end of the conveyor belt 2, and the bottom of the guide chute 3 has a downward-facing discharge port, that is, the discharge port faces the bearing surface of the conveyor belt 2 (which refers to the side of the conveyor belt 2 that is responsible for bearing the material), ensuring that the material falls onto the conveyor belt 2 after passing through the guide chute 3.

[0045] like Figure 3 As shown, a heating film 31 is provided on the outer wall of the material guide trough 3. The heating film 31 is connected to a power source via wires. When current passes through the heating film 31, electrical energy is converted into heat energy due to resistance, thereby achieving the effect of heating the material guide trough 3. In addition, the circuit connecting the heating film 31 to the power source usually has a switch (e.g., a relay). The switch is connected to a controller via a signal line, so that the controller can control the start and stop of the heating film 31 through the switch.

[0046] like Figure 3 As shown, a temperature sensor 32 is installed inside the feed trough 3, and the signal lead of the temperature sensor 32 extends out of the feed trough 3 and connects to the controller. Thus, the temperature sensor 32 can transmit the real-time monitored internal temperature of the feed trough 3 to the controller.

[0047] The controller can link the temperature sensor 32 and the heating film 31 according to a preset program. Specifically, a temperature threshold is set in the preset program. When the real-time temperature is lower than the preset temperature threshold, it indicates that the internal temperature of the guide trough 3 is too low and is prone to sticking. Then, the controller controls the heating film 31 to turn on. The heating film 31 heats the guide trough 3, which can effectively keep the internal temperature of the guide trough 3 within a suitable temperature range, prevent the material from freezing and sticking to the guide trough 3, and thus ensure that the material falls smoothly onto the conveyor belt 2 for transportation.

[0048] The ultrasonic cleaner 4 is located below the discharge end of the conveyor belt 2 and close to the return surface of the conveyor belt 2.

[0049] It should be noted that the discharge end of conveyor belt 2 refers to the end where the material will naturally fall off conveyor belt 2.

[0050] The ultrasonic cleaner 4 is an instrument that cleans contaminants by generating shock waves through high-frequency vibration. The ultrasonic cleaner 4 is positioned below the discharge end of the conveyor belt 2 and close to the return surface of the conveyor belt 2 (the side of the conveyor belt 2 opposite to its carrying surface). Therefore, even if some material remains frozen on the conveyor belt 2 after unloading, the ultrasonic cleaner 4 can clean the frozen material during the initial stage of the return journey, preventing the material from freezing and reducing wear and resistance on the return section of the conveyor belt 2 (the part of the conveyor belt 2 that does not carry the transported material). This improves the stability and conveying efficiency of the conveyor belt 2.

[0051] Therefore, the antifreeze and anti-stick belt conveyor provided by this utility model, under the combined action of the antifreeze and anti-stick guide trough 3, the antifreeze and anti-stick conveyor belt 2 and the ultrasonic cleaner 4, can effectively prevent the material from freezing and sticking to the guide trough 3 and the conveyor belt 2 in low temperature environment, thereby improving the operating stability and conveying efficiency of the belt conveyor in low temperature environment.

[0052] Based on the above embodiments, and considering the specific configuration of the conveyor belt 2, as a preferred option, please refer to... Figure 2 The conveyor belt 2 includes an anti-stick surface layer 21 and a cold-resistant elastic layer 22 arranged sequentially along the direction from the top surface to the bottom surface of the conveyor belt 2.

[0053] The anti-stick surface layer 21 can be made of Teflon coating or polyethylene film, which has an extremely low coefficient of friction and can effectively prevent materials from sticking to the surface of the conveyor belt 2 during transportation. Of course, the anti-stick surface layer 21 can also be made of films made of other low-friction materials, and is not the only option.

[0054] The cold-resistant elastic layer 22 can be made of neoprene rubber, which has good low-temperature resistance, maintaining the flexibility of the conveyor belt 2 and preventing it from cracking in cold conditions. Of course, the anti-stick surface layer 21 can also be made of films made of other cold-resistant elastic materials, and is not the only option.

[0055] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 The conveyor belt 2 also includes a heat insulation layer 23, a tensile layer 24, and an antifreeze layer 25, which are arranged sequentially on the side of the cold-resistant elastic layer 22 facing away from the anti-stick surface layer 21. That is, the anti-stick surface layer 21, the cold-resistant elastic layer 22, the heat insulation layer 23, the tensile layer 24, and the antifreeze layer 25 are arranged sequentially along the direction from the bearing surface of the conveyor belt 2 to its return surface to form the conveyor belt 2.

[0056] The insulation layer 23 can be a film made of a rubber and glass fiber composite material, which can increase the heat insulation performance of the conveyor belt 2 and prevent the surface of the conveyor belt 2 from freezing or the material from freezing due to rapid temperature changes. Moreover, the addition of glass fiber gives the intermediate layer strong tensile strength and durability. Of course, the insulation layer 23 can also be made of films made of other heat-insulating materials, and is not the only option.

[0057] The tensile layer 24 can be made of a film of high-strength polyester fiber, which can improve the tensile strength of the conveyor belt 2, ensure that the conveyor belt 2 can withstand greater tension during transportation, and prevent breakage or deformation in low-temperature environments, thereby effectively enhancing the stability of the conveyor belt 2. Of course, the tensile layer 24 can also be made of films of other high tensile strength materials, and is not the only option.

[0058] The antifreeze layer 25 can be made of polyvinyl chloride film, which can improve the adhesion and stability of the conveyor belt 2, ensuring that the conveyor belt 2 can work smoothly, while preventing the conveyor belt 2 from freezing and cracking or hardening in low-temperature environments. Of course, the antifreeze layer 25 can also be made of other films with high antifreeze properties, and is not the only option.

[0059] Based on the above embodiments, and considering the specific arrangement of the heating film 31, as a preferred embodiment, the heating film 31 is evenly applied to the outer wall of the feed trough 3 by an adhesive.

[0060] Understandably, the heating film 31 is adhered to the outer wall of the feed trough 3 using adhesive. This ensures a tight fit between the heating film 31 and the outer wall of the feed trough 3, allowing the heat from the heating film 31 to be effectively transferred to the feed trough 3, thus enhancing the heating effect. Furthermore, the shape and size of the heating film 31 can be cut and pasted according to the shape and size of the feed trough 3, ensuring that the heating film 31 is evenly distributed on the outer wall of the feed trough 3, avoiding overlap or excessive gaps. This guarantees uniform heat distribution, ensuring that the feed trough 3 is heated evenly and preventing heating dead zones that could cause material adhesion.

[0061] Preferably, the adhesive can be a special adhesive that is resistant to high temperatures and has good insulation properties.

[0062] Based on the above embodiments, in order to realize the local heating function of the material guide trough 3, as a preferred embodiment, the heating film 31 is spliced ​​together by a number of wall films evenly arranged around the outer peripheral wall of the material guide trough 3; the temperature sensor 32 is set as a number and evenly arranged around the inner peripheral wall of the material guide trough 3, and one temperature sensor 32 corresponds to at least one wall film.

[0063] Taking a rectangular feed trough 3 as an example, in one specific embodiment, three membranes are attached to each of the four outer walls of the feed trough 3, and two temperature sensors 32 are disposed adjacent to each of the four inner walls of the feed trough 3. Furthermore, on the same sidewall of the feed trough 3, each temperature sensor 32 is located between two adjacent membranes. Figure 3 As shown. Thus, when any temperature sensor 32 detects an excessively low temperature, indicating that the internal temperature of the feed trough 3 in its vicinity is too low, the controller can only control the heating of the two films near that temperature sensor 32 to heat the locally low-temperature area of ​​the feed trough 3. This setup has the following advantages: firstly, heating only the locally low-temperature area significantly reduces the heating area and time, resulting in high efficiency and energy saving. Secondly, it avoids the situation where heating areas with normal temperatures could cause high-temperature damage to the material.

[0064] Based on the above embodiments, as a preferred embodiment, the signal lead of the temperature sensor 32 is led out to the outside of the feed trough 3 through a waterproof sealing joint.

[0065] The signal lead of temperature sensor 32 needs to be connected to a controller located outside the feed trough 3. The signal lead is led out of the feed trough 3 through a waterproof sealing joint. The waterproof sealing joint has the functions of waterproofing and sealing, which can prevent short circuits and leakage of the signal lead, so as to be better suited to low temperature and humid environments and ensure the reliable operation of temperature sensor 32.

[0066] Based on the above embodiments, as a preferred embodiment, the power cord connecting the heating film 31 to the power source and the signal cord connecting the heating film 31 to the controller are both wrapped with insulating sleeves. The insulating sleeves also serve a waterproof and sealing function. Wrapping the exposed power cords and signal cords of the heating film 31 with insulating sleeves can prevent short circuits and leakage, thus better suiting low-temperature and humid environments and ensuring reliable operation of the heating film 31.

[0067] Based on the above embodiments, and considering the specific configuration of the ultrasonic cleaner 4, as a preferred option, please refer to... Figure 4 The ultrasonic cleaner 4 includes a housing 41, an ultrasonic power supply 42, and several ultrasonic transducers 43. The housing 41 is fixed on the conveyor frame 1 and a preset distance is left between its top end and the return surface of the conveyor belt 2. The ultrasonic power supply 42 is located inside the housing 41 on the side away from its top end. Several ultrasonic transducers 43 are spaced apart at the top end inside the housing 41 and are all electrically connected to the ultrasonic power supply 42.

[0068] Specifically, the housing 41 is fixed to the conveyor frame 1. The ultrasonic power supply 42 and several ultrasonic transducers 43 are installed inside the housing 41 so that the ultrasonic cleaner 4 is firmly located below the discharge end of the conveyor belt 2. A preset distance is maintained between the top of the housing 41 and the return surface of the conveyor belt 2. This preset distance can be determined according to the actual application conditions; generally, the smaller the preset distance, the more significant the cleaning effect. Furthermore, the ultrasonic power supply 42, also known as an ultrasonic generator, converts electrical energy into a high-frequency AC signal that matches the ultrasonic transducer 43 and transmits it to the ultrasonic transducer 43. The ultrasonic transducer 43 then converts the high-frequency AC signal into mechanical vibration (ultrasound) through the inverse piezoelectric effect. Therefore, the several ultrasonic transducers 43, spaced apart at the top of the housing 41, can transmit ultrasonic waves to the return surface of the conveyor belt 2, causing the material adhering to the return surface of the conveyor belt 2 to vibrate, thereby achieving the purpose of cleaning the material.

[0069] It should also be noted that, compared with conventional spraying of antifreeze or contact cleaning, using ultrasonic cleaner 4 to clean the material adhering to conveyor belt 2 through contact cleaning can not only reduce damage to conveyor belt 2, but also generate a strong impact force through high-frequency vibration, thereby improving the cleaning effect.

[0070] Based on any of the above embodiments, and considering the specific arrangement of the driving device, as a preferred option, please refer to... Figure 1 The driving device includes a feed end roller 6, a discharge end roller 7, a motor, and several idler rollers 8. The feed end roller 6 and the discharge end roller 7 are rotatably mounted at both ends of the conveyor frame 1. The motor drives and connects to the discharge end roller 7. Some idler rollers 8 are evenly arranged on the upper end surface of the conveyor frame 1, and other idler rollers 8 are evenly arranged on the lower end surface of the conveyor frame 1. The conveyor belt 2 connects the feed end roller 6 and the discharge end roller 7 and rotates around the several idler rollers 8.

[0071] Thus, the motor drives the discharge end roller 7 to rotate, generating traction force, which can drive the conveyor belt 2 to rotate around the feed end roller 6, several idlers 8, and the discharge end roller 7. Among them, the upper idler group is mainly used to support the weight of the carrying section of the conveyor belt 2 and the material on it, preventing the conveyor belt 2 from sagging and ensuring the stable operation of the conveyor belt 2; the lower idler group is mainly used to disperse the contact point between the return section of the conveyor belt 2 and the conveyor frame 1, avoiding sliding friction and reducing the energy consumption and wear of the conveyor belt 2.

[0072] Based on any of the above embodiments, and considering the specific configuration of the belt conveyor unloading, as a preferred option, please refer to... Figure 1The belt conveyor also includes a hopper 5, the inside of which is inserted into the discharge end of the conveyor belt 2. The inside of the hopper 5 is provided with at least one cleaner 9, which is located below the turning point of the discharge end of the conveyor belt 2 and has an elastic scraper that contacts the conveyor belt 2. Along the conveying direction of the conveyor belt 2, the cleaner 9 is located behind the ultrasonic cleaner 4.

[0073] Specifically, the discharge end of the conveyor belt 2 (i.e., the end with the discharge end roller 7) is inserted into the inside of the funnel 5, allowing the material to fall through the funnel 5 into a designated area. The inside of the funnel 5 contains at least one cleaner 9, located below the discharge end of the conveyor belt 2 (i.e., the discharge end roller 7). The cleaner 9 has an elastic scraper made of elastic material, which contacts the conveyor belt 2 and is positioned along the conveying direction of the conveyor belt 2. The cleaner 9 is located behind the ultrasonic cleaner 4. In this way, after the conveyor belt 2 has finished unloading, the cleaner 9 can remove any material still adhering to the conveyor belt 2. The elastic scraper is typically made of polyurethane material, which has a certain degree of elasticity and can automatically adjust the contact pressure between the scraper and the conveyor belt 2 to avoid damaging the conveyor belt 2 while ensuring effective cleaning. After the cleaner 9 finishes cleaning, the ultrasonic cleaner 4 will remove any residual material that the cleaner 9 did not clean. Thus, the cleaner 9 and the ultrasonic cleaner 4 work together to clean the conveyor belt 2 in sequence, which can greatly improve the cleaning effect of the material adhering to the conveyor belt 2, thereby effectively improving the operational stability and conveying efficiency of the belt conveyor in low-temperature environments.

[0074] In one specific embodiment, please refer to Figure 1 and Figure 5 Two cleaners 9 are provided. One cleaner 9 is located slightly below the center line of the discharge end roller 7, and its elastic scraper contacts the bearing surface of the conveyor belt 2. It is responsible for removing large particles of material that adhere to the bearing surface of the conveyor belt 2 after unloading. The other cleaner 9 is located below the discharge end roller 7, and its elastic scraper contacts the return surface of the conveyor belt 2. It is responsible for removing small residual materials that were not cleaned by the first section cleaner 9.

[0075] Regarding the specific placement of the ultrasonic cleaner 4, please refer to [reference needed] as an optimal option. Figure 1 A horizontal space is left between the lower idler assembly and the funnel 5, within which an ultrasonic cleaner 4 is installed. This arrangement places the ultrasonic cleaner 4 outside the funnel 5, saving space in the funnel 5 and preventing the ultrasonic waves generated by the ultrasonic cleaner 4 from affecting the stability of the funnel 5 and its internal components. Furthermore, along the conveying direction of the conveyor belt 2, the ultrasonic cleaner 4 is positioned behind the lower idler assembly. This allows it to clean any material adhering to the conveyor belt 2 during its return journey before it comes into contact with the idler rollers 8, thus preventing increased friction between the conveyor belt 2 and the idler rollers 8 and reducing wear on both.

[0076] Regarding the specific configuration of conveyor frame 1, please refer to the following as an preferred option. Figure 1 The conveyor frame 1 includes a tail frame 11, an intermediate frame 12, and a head frame 13. The intermediate frame 12 is located between the tail frame 11 and the head frame 13. The tail frame 11 is fixed to the ground and is equipped with a rotatable feed end roller 6. The lower end face of the intermediate frame 12 is evenly provided with several support legs 14 that are fixed to the ground. The end of the intermediate frame 12 adjacent to the feed end roller 6 is connected to the outer wall of the guide trough 3 through several connecting plates 33. The upper end face of the intermediate frame 12 is evenly provided with several idler rollers 8, and the lower end face of the intermediate frame 12 is also evenly provided with several idler rollers 8. The head frame 13 is fixed to the ground and is equipped with a rotatable discharge end roller 7 that extends into the funnel 5. An ultrasonic cleaner 4 is provided below the other end of the intermediate frame 12 outside the funnel 5.

[0077] It should be noted that the conveyor frame 1 adopts the above-mentioned structural setting, which ensures balanced force distribution and is suitable for high-altitude and long-distance conveying operations.

[0078] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0079] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0080] The above provides a detailed description of the antifreeze and anti-stick belt conveyor provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
