Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and specifically to an automatic feeding device for an incinerator. Background Art

[0002] Automatic feeding devices for incinerators are generally designed to effectively transport solid waste or biomass fuels into the combustion chamber for incineration. The automatic feeding device can not only improve the efficiency and safety of the incinerator, but also reduce the need for manual operation and lower the operating cost. These devices mainly consist of the following parts:

[0003] 1. Hopper: Used to store and preprocess waste or biomass.

[0004] 2. Conveying system: Transports the materials in the hopper to the combustion chamber. This usually includes chain conveyors, screw conveyors or other types of conveying equipment, and the specific selection depends on the nature of the waste and the design of the incinerator.

[0005] 3. Feeding control system: Monitors and adjusts the feeding rate and quantity of the materials to ensure that the incinerator can maintain stable combustion conditions.

[0006] However, when the existing feeding equipment is in use, the flow rate of the hopper during discharging is uneven, which makes the fuel flow rate into the incinerator uneven and easily leads to unstable fuel combustion in the incinerator. Summary of the Invention

[0007] The purpose of the present invention is to provide an automatic feeding device for an incinerator to solve the problems raised in the above background art.

[0008] To solve the above technical problems, the present invention provides the following technical solution: The automatic feeding device includes a frame, a hopper, a control system, a conveying system and an adjusting system. The hopper is fixedly connected to the frame, the control system is fixedly connected to the frame, the control system is electrically connected to the conveying system and the adjusting system, the conveying system is fixedly connected to the frame, the adjusting system is fixedly connected to the frame, and the adjusting system is used to adjust the distribution state of the materials. There is a discharge port on one side of the frame far from the hopper.

[0009] The frame is placed on the ground to provide stable support for each system. The hopper is used to store materials and input the materials onto the conveying system. When the automatic feeding device is working, the control system starts the conveying system, and the materials in the hopper fall onto the conveying system at a certain rate. Then the conveying system transports the materials to the discharge port and then into the incinerator for combustion. At the same time, in order to ensure the stable flow rate of the conveying system when transporting materials, the adjusting system adjusts the materials passing through the conveying system in real time to make their distribution tend to be uniform, so as to ensure the stable combustion of the materials entering the incinerator.

[0010] Further, the conveying system includes a conveyor belt, a driving roller, a driving motor, and a redirecting roller. The rotating shafts of the driving roller and the redirecting roller are rotatably connected to the frame. The driving motor is fixedly connected to the frame, and the output end of the driving motor is drivingly connected to the driving roller. The conveyor belt is wound around the driving roller and the redirecting roller. There are several redirecting rollers arranged along the movement direction of the conveyor belt. The driving motor is electrically connected to the control system.

[0011] The driving motor is the main power source of the conveying system. The control system is used to control the opening and closing of the driving motor. Driven by the driving motor, the driving roller rotates around the frame, thereby driving the conveyor belt wound around the driving roller and the redirecting roller to move. After the materials stored in the hopper fall onto the conveyor belt, they will gradually move towards the discharge port under the drive of the conveyor belt and finally fall into the incinerator for combustion.

[0012] Further, the regulating system includes a power roller, a transmission roller, a guiding roller, a regulating motor, a transmission mechanism, a conveyor belt, and a detection component. The power roller and the transmission roller are rotatably connected to the frame. The conveyor belt is wound around the power roller and the guiding roller. The transmission roller is drivingly connected to the conveyor belt. The regulating motor is fixedly connected to the frame, and the output end of the regulating motor is drivingly connected to the transmission mechanism. The transmission mechanism is respectively drivingly connected to the power roller and the transmission roller. The detection component is fixedly connected to the frame. The detection component is used to measure the weight of the materials passing through the conveyor belt.

[0013] There will be a phenomenon of uneven weight of the materials falling from the hopper onto the conveyor belt, with a section being light in weight and a section being heavy in weight. The regulating system redistributes the materials on the conveyor belt, transfers a part with a large weight to the light-weight area, realizes dynamic compensation for the materials on the conveyor belt, makes the distribution of the materials on the conveyor belt tend to be uniform, thereby ensuring that the weight of the materials entering the incinerator remains uniform, and improving the combustion stability of the incinerator; when the materials on the conveyor belt move to the conveyor belt, the regulating motor is used to drive the power roller, thereby driving the conveyor belt to move along the guiding roller. There are corresponding guiding plates between the conveyor belt and the conveyor belt. Under the action of inertia, the materials will be transferred from the conveyor belt along the guiding plate to the conveyor belt. The rotational speeds of the conveyor belt and the conveyor belt are the same, so as to ensure the stability of the transfer; in the initial state, the rotational speeds of the power roller and the transmission roller are the same. When the materials are transferred to the conveyor belt, the detection component is used to judge the weight of the materials. When the weight of the materials passing through the conveyor belt is light, the transmission mechanism acts to increase the rotational speed transmitted to the transmission roller, so that the transmission roller and the power roller rotate at a differential speed. The rotational speed of the transmission roller increases, and the rotational speed of the conveyor belt wound around the transmission roller can be correspondingly increased, thereby increasing the moving speed of the materials on the conveyor belt and increasing the weight of the materials transferred to the conveyor belt per unit time, realizing dynamic compensation for the weight of the materials. When the weight of the materials on the conveyor belt is in the standard state, the transmission mechanism acts to restore the rotational speeds of the power roller and the transmission roller to be the same.

[0014] Furthermore, the transmission mechanism includes a driving shaft, a driven shaft, a first movable sleeve, a second movable sleeve, a movable component, a driving wheel, a driven wheel and a slider. One end of the driving shaft is in transmission connection with the output end of the adjusting motor, and the other end of the driving shaft is in transmission connection with the power roller. One end of the driven shaft is rotatably connected to the frame, and the other end of the driven shaft is in transmission connection with the transmission roller. The driving wheel is fixedly connected to the driving shaft, and the driven wheel is fixedly connected to the driven shaft. The first movable sleeve is slidably connected to the driving shaft, and the second movable sleeve is slidably connected to the driven shaft. One end of the movable component is hinged to the first movable sleeve, and the other end of the movable component is hinged to the second movable sleeve. A plurality of sliding grooves are provided on both the driving wheel and the driven wheel, and the slider is slidably connected to the sliding groove. A transmission belt is sleeved on the slider, and the slider is hinged to the first movable sleeve and the second movable sleeve respectively through a connecting rod.

[0015] The adjusting motor transmits torque to the driving shaft, thereby driving the driving shaft to rotate at a fixed speed, and further driving the power roller to rotate at a certain speed. In the initial state, the diameter of the transmission shaft composed of the sliders in a plurality of sliding grooves on the driving wheel and the driven wheel is the same. Driven by the transmission belt sleeved on the slider, the rotational speeds of the power roller and the transmission roller are kept consistent. When it is necessary to increase the rotational speed of the transmission roller, the movable component acts, pushing the first movable sleeve to move along the driving shaft towards the driving wheel, and the second movable sleeve to move along the driven shaft away from the driven wheel, so that the diameter of the transmission shaft composed of the sliders on the driving wheel becomes larger, and the diameter of the transmission shaft composed of the sliders on the driven wheel becomes smaller. Since the rotational speed of the driving wheel is fixed, under the transmission of the transmission belt, the rotational speed of the driven wheel is greater than that of the driving wheel, so that the transmission roller and the power roller form a differential rotation.

[0016] Furthermore, the detection component includes a support plate, the support plate is fixedly connected to the frame, a pressure strain gauge is provided on the support plate, the detection end of the pressure strain gauge abuts against the conveyor belt, and the pressure strain gauge is electrically connected to the movable component.

[0017] When the material is transferred onto the conveyor belt, under the action of the self-gravity of the material, the conveyor belt will be pressed against the pressure strain gauge on the support plate. Under the action of the gravity of the material, the pressure strain gauge will be stretched by force, making the resistance value of the pressure strain gauge become larger. The pressure strain gauge is externally connected to a power supply, so that the current transmitted to the movable component will decrease accordingly. The smaller the weight of the material on the conveyor belt, the smaller the resistance value of the pressure strain gauge, and the greater the current transmitted to the movable component.

[0018] Furthermore, the movable component includes a connecting seat, a telescopic rod, a gear, a rack, a reset spring and an electromagnet. The connecting seat is tightly connected to the frame, one end of the telescopic rod is hinged to the first movable sleeve, and the other end of the telescopic rod is hinged to the second movable sleeve. A transmission cavity is provided on the connecting seat, and the gear is located in the transmission cavity. The gear is tightly connected to the telescopic rod, the gear is rotatably connected to the connecting seat, the rack is slidingly connected to the transmission cavity, the rack is meshed with the gear, one end of the reset spring is tightly connected to the rack, the other end of the reset spring is tightly connected to the inner wall of the transmission cavity, the electromagnet is tightly connected to the connecting seat, the electromagnet is located in the transmission cavity at one end away from the reset spring, and the opposite ends of the rack and the electromagnet are provided with repelling magnets, the opposite ends of the repelling magnet and the electromagnet are opposite magnetic poles, and the electromagnet is electrically connected to the pressure strain gauge.

[0019] The connecting seat is fixed on the frame to provide stable support for the movable component. In the initial state, the telescopic rod is in a retracted state. When the weight of the material on the conveyor belt is light, the current transmitted to the electromagnet through the pressure strain gauge will increase, and the magnetism of the electromagnet will increase. Because the rack and the electromagnet are provided with repelling magnets at the opposite ends, under the effect of opposites attracting each other, the rack is driven to move toward the electromagnet, and the reset spring is stretched by force, thereby driving the gear to rotate, and then driving the telescopic rod to rotate and extend along the connecting seat. Driven by the telescopic rod, the first movable sleeve and the second movable sleeve slide along the driving shaft and the driven shaft respectively, so that the slider on the driving wheel expands outward and the slider on the driven wheel contracts inward, thereby realizing automatic adjustment of the speed ratio between the driving wheel and the driven wheel according to the weight of the material on the conveyor belt.

[0020] Furthermore, the automatic feeding device also includes a tightening mechanism, which is used to adjust the tightness of the conveyor belt.

[0021] When the transmission roller accelerates, it will pull the conveyor belt wrapped around the transmission roller. In order to prevent the conveyor belt from being pulled and broken, the tightness of the conveyor belt is adjusted through the tightening mechanism to dynamically compensate the conveyor belt.

[0022] Furthermore, the tightening mechanism includes a first adjusting roller, a second adjusting roller, a push rod and a guide block. The rotating axes of the first adjusting roller and the second adjusting roller are rotatably connected to the guide block. A guide groove is provided on the frame. The guide block is slidably connected to the guide groove. The push rod is tightly connected to the frame. The push rods are staggered in the guide grooves. The output ends of the push rods are transmission-connected to the guide block. The conveyor belt is S-shaped and wound around the first adjusting roller and the second adjusting roller.

[0023] The conveyor belt wound in an S shape on the first adjusting roller and the second adjusting roller is in a taut state. When the driving roller rotates faster, the push rod contracts, driving the guide block to move to both sides along the guide groove, stretching the conveyor belt wound on the first adjusting roller and the second adjusting roller, dynamically compensating the conveyor belt to prevent the conveyor belt from breaking.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: After the material is transferred to the conveyor belt, the detection component is used to judge the weight of the material. When the weight of the material passing through the conveyor belt is relatively light, the transmission mechanism operates to increase the rotational speed transmitted to the transmission roller, enabling the transmission roller and the power roller to rotate at a differential speed. As the rotational speed of the transmission roller increases, the rotational speed of the conveyor belt wound around the transmission roller can be correspondingly increased, thereby increasing the moving speed of the material on the conveyor belt, increasing the weight of the material transferred to the conveyor belt per unit time, achieving dynamic compensation for the material weight, and improving the uniformity of transportation.

[0025] When the weight of the material on the conveyor belt is relatively light, the current transmitted to the electromagnet through the pressure strain gauge will increase, and the magnetism of the electromagnet will increase. Since a repulsive magnet is provided at the opposite end of the rack and the electromagnet, under the action of opposite-sex attraction, the rack is driven to move towards the electromagnet direction, thereby driving the gear to rotate, and further driving the telescopic rod to rotate and extend along the connecting seat. The first movable sleeve and the second movable sleeve are each driven by the telescopic rod to slide along the driving shaft and the driven shaft, so that the slider on the driving wheel expands outwards and the slider on the driven wheel contracts inwards, realizing automatic adjustment of the rotational speed ratio between the driving wheel and the driven wheel according to the weight of the material on the conveyor belt.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] The present invention provides a technical solution:

[0039] As Figure 1 shown, the automatic feeding device includes a frame 1, a hopper 2, a control system 3, a conveying system 4, and an adjusting system 5. The hopper 2 is fixedly connected to the frame 1, the control system 3 is fixedly connected to the frame 1, the control system 3 is electrically connected to the conveying system 4 and the adjusting system 5, the conveying system 4 is fixedly connected to the frame 1, the adjusting system 5 is fixedly connected to the frame 1, and the adjusting system 5 is used to adjust the distribution state of the material. A discharge port 11 is provided on one side of the frame 1 away from the hopper 2.

[0040] The frame 1 is placed on the ground to provide stable support for each system. The hopper 2 is used to store the material and input the material onto the conveying system 4. When the automatic feeding device is working, the control system 3 starts the conveying system 4, and the material in the hopper falls onto the conveying system 4 at a certain rate. Then, the conveying system 4 conveys the material to the discharge port 11 and then enters the incinerator for combustion. At the same time, in order to ensure the stable flow rate of the conveying system 4 when conveying the material, the adjusting system 5 adjusts the material passing through the conveying system 4 in real time to make its distribution tend to be uniform, so as to ensure the stable combustion of the material entering the incinerator.

[0041] As Figure 2 shown, the conveying system 4 includes a conveyor belt 41, a driving roller 42, a driving motor 43 and a redirecting roller 44. The rotating shafts of the driving roller 42 and the redirecting roller 44 are rotatably connected to the frame 1. The driving motor 43 is fixedly connected to the frame 1. The output end of the driving motor 43 is drivingly connected to the driving roller 42. The conveyor belt 41 is wound around the driving roller 42 and the redirecting roller 44. A plurality of redirecting rollers 44 are arranged along the movement direction of the conveyor belt 41. The driving motor 43 is electrically connected to the control system 3.

[0042] The driving motor 43 is the main power source of the conveying system 4. The control system 3 is used to control the opening and closing of the driving motor 43. Driven by the driving motor 43, the driving roller 42 rotates around the frame 1, thereby driving the conveyor belt 41 wound around the driving roller 42 and the redirecting roller 44 to move. After the materials stored in the hopper 2 fall onto the conveyor belt 41, they will gradually move towards the discharge port 11 under the drive of the conveyor belt 41 and finally fall into the incinerator for combustion.

[0043] As Figures 3 - 7 shown, the adjusting system 5 includes a power roller 51, a transmission roller 52, a guiding roller 53, an adjusting motor 54, a transmission mechanism 55, a conveyor belt 56 and a detection assembly 57. The power roller 51 and the transmission roller 52 are rotatably connected to the frame 1. The conveyor belt 56 is wound around the power roller 51 and the guiding roller 53. The transmission roller 52 is drivingly connected to the conveyor belt 41. The adjusting motor 54 is fixedly connected to the frame 1. The output end of the adjusting motor 54 is drivingly connected to the transmission mechanism 55. The transmission mechanism 55 is respectively drivingly connected to the power roller 51 and the transmission roller 52. The detection assembly 57 is fixedly connected to the frame 1. The detection assembly 57 is used to measure the weight of the materials passing through the conveyor belt 56.

[0044] The materials falling from the hopper 2 onto the conveyor belt 41 may have uneven weights, with some parts being light and some parts being heavy. The adjustment system 5 redistributes the materials on the conveyor belt 41, transferring the heavier part to the lighter area to achieve dynamic compensation for the materials on the conveyor belt 41, making the distribution of the materials on the conveyor belt 41 tend to be uniform, thereby ensuring that the weights of the materials entering the incinerator are uniform and improving the combustion stability of the incinerator. When the materials on the conveyor belt 41 move to the transfer belt 56, the adjustment motor 54 drives the power roller 51, thereby driving the transfer belt 56 to move along the guide roller 53. Corresponding guide plates are provided between the conveyor belt 41 and the transfer belt 56. Under the action of inertia, the materials will be transferred from the conveyor belt 41 to the transfer belt 56 along the guide plates. The rotation speeds of the transfer belt 56 and the conveyor belt 41 are the same to ensure the stability of the transfer. In the initial state, the rotation speeds of the power roller 51 and the drive roller 52 are the same. After the materials are transferred to the transfer belt 56, the detection component 57 is used to judge the weight of the materials. When the weight of the materials passing through the transfer belt 56 is light, the transmission mechanism 55 acts to increase the rotation speed transmitted to the drive roller 52, making the drive roller 52 rotate differentially with the power roller 51. As the rotation speed of the drive roller 52 increases, the rotation speed of the conveyor belt 41 wound around the drive roller 52 can be correspondingly increased, thereby increasing the moving speed of the materials on the conveyor belt 41 and increasing the weight of the materials transferred to the transfer belt 56 per unit time to achieve dynamic compensation for the material weight. When the weight of the materials on the transfer belt 56 is in the standard state, the transmission mechanism 55 acts to restore the rotation speeds of the power roller 51 and the drive roller 52 to be the same.

[0045] As Figures 3 - 7 shown, the transmission mechanism 55 includes a driving shaft 551, a driven shaft 552, a first movable sleeve 553, a second movable sleeve 554, a movable component 555, a driving wheel 556, a driven wheel 557 and a slider 558. One end of the driving shaft 551 is in transmission connection with the output end of the adjustment motor 54, and the other end of the driving shaft 551 is in transmission connection with the power roller 51. One end of the driven shaft 552 is rotatably connected to the frame 1, and the other end of the driven shaft 552 is in transmission connection with the drive roller 52. The driving wheel 556 is fixedly connected to the driving shaft 551, and the driven wheel 557 is fixedly connected to the driven shaft 552. The first movable sleeve 553 is slidably connected to the driving shaft 551, and the second movable sleeve 554 is slidably connected to the driven shaft 552. One end of the movable component 555 is hinged to the first movable sleeve 553, and the other end of the movable component 555 is hinged to the second movable sleeve 554. A plurality of chute grooves are provided on both the driving wheel 556 and the driven wheel 557. The slider 558 is slidably connected to the chute grooves. A transmission belt 559 is sleeved on the slider 558. The slider 558 is hinged to the first movable sleeve 553 and the second movable sleeve 554 respectively through connecting rods.

[0046] The adjusting motor 54 transmits torque to the driving shaft 551, thereby driving the driving shaft 551 to rotate at a fixed speed, and further driving the power roller 51 to rotate at a certain speed. In the initial state, the diameter of the transmission shaft composed of the sliders 558 in several chutes on the driving wheel 556 and the driven wheel 557 is the same. Driven by the transmission belt 559 wound around the sliders 558, the rotational speeds of the power roller 51 and the transmission roller 52 are kept consistent. When it is necessary to increase the rotational speed of the transmission roller 52, the movable assembly 555 acts, pushing the first movable sleeve 553 to move along the driving shaft 551 towards the driving wheel 556, and the second movable sleeve 554 to move along the driven shaft 552 away from the driven wheel 557. This makes the diameter of the transmission shaft composed of the sliders 558 on the driving wheel 556 larger, and the diameter of the transmission shaft composed of the sliders on the driven wheel 557 smaller. Since the rotational speed of the driving wheel 556 is fixed, under the transmission of the transmission belt 559, the rotational speed of the driven wheel 557 is greater than that of the driving wheel 556, causing the transmission roller 52 and the power roller 51 to rotate differentially.

[0047] As Figure 4 shown, the detection assembly 57 includes a support plate 571. The support plate 571 is fixedly connected to the frame 1. A pressure strain gauge 572 is provided on the support plate 571. The detection end of the pressure strain gauge 572 abuts against the conveyor belt 56. The pressure strain gauge 572 is electrically connected to the movable assembly 555.

[0048] When the material is transferred onto the conveyor belt 56, under the action of the self - weight of the material, the conveyor belt 56 will be pressed against the pressure strain gauge 572 on the support plate 571. Under the action of the gravity of the material, the pressure strain gauge 572 will be stretched by the force, causing the resistance value of the pressure strain gauge 572 to increase. The pressure strain gauge 572 is externally powered, so the current transmitted to the movable assembly 555 will decrease accordingly. The smaller the weight of the material on the conveyor belt 56, the smaller the resistance value of the pressure strain gauge 572, and the greater the current transmitted to the movable assembly 555.

[0049] As Figures 5 - 7As shown, the movable component 555 includes a connecting seat 5551, a telescopic rod 5552, a gear 5553, a rack 5554, a return spring 5555, and an electromagnet 5556. The connecting seat 5551 is fixedly connected to the frame 1. One end of the telescopic rod 5552 is hinged to the first movable sleeve 553, and the other end of the telescopic rod 5552 is hinged to the second movable sleeve 554. A transmission cavity is provided on the connecting seat 5551. The gear 5553 is located in the transmission cavity. The gear 5553 is fixedly connected to the telescopic rod 5552 and rotatably connected to the connecting seat 5551. The rack 5554 is slidably connected to the transmission cavity and meshes with the gear 5553. One end of the return spring 5555 is fixedly connected to the rack 5554, and the other end of the return spring 5555 is fixedly connected to the inner wall of the transmission cavity. The electromagnet 5556 is fixedly connected to the connecting seat 5551 and is located at one end of the transmission cavity away from the return spring 5555. A repelling magnet 5557 is provided at the facing end of the rack 5554 and the electromagnet 5556. The facing ends of the repelling magnet 5557 and the electromagnet 5556 are of opposite magnetic poles. The electromagnet 5556 is electrically connected to the pressure strain gauge 572.

[0050] The connecting seat 5551 is fixed on the frame 1 to provide stable support for the movable component 555. In the initial state, the telescopic rod 5552 is in a contracted state. When the weight of the material on the conveyor belt 56 is relatively light, the current transmitted to the electromagnet 5556 through the pressure strain gauge 572 will increase, and the magnetism of the electromagnet 5556 will increase. Since a repelling magnet 5557 is provided at the facing end of the rack 5554 and the electromagnet 5556, under the action of opposite-sex attraction, the rack 5554 is driven to move towards the electromagnet 5556, and the return spring 5555 is stretched under force, thereby driving the gear 5553 to rotate, and further driving the telescopic rod 5552 to rotate and extend along the connecting seat 5551. The first movable sleeve 553 and the second movable sleeve 554 are each driven by the telescopic rod 5552 to slide along the driving shaft 551 and the driven shaft 552 respectively, so that the slider 558 on the driving wheel 556 expands outwards, and the slider 558 on the driven wheel 557 contracts inwards, realizing automatic adjustment of the speed ratio between the driving wheel 556 and the driven wheel 557 according to the weight of the material on the conveyor belt.

[0051] As Figures 8 - 9 shown, the automatic feeding device further includes a tightening mechanism 6, and the tightening mechanism 6 is used to adjust the tightness of the conveyor belt 41.

[0052] When the driving roller 52 rotates at an accelerated speed, it will pull the conveyor belt 41 wound around the driving roller 52. In order to prevent the conveyor belt 41 from being pulled and broken, the tightness of the conveyor belt is adjusted through the tightening mechanism 6 to perform dynamic compensation on the conveyor belt 41.

[0053] As Figures 8 - 9As shown in the figure, the tightening mechanism 6 includes a first adjusting roller 61, a second adjusting roller 62, a push rod 63 and a guide block 64. The rotating shafts of the first adjusting roller 61 and the second adjusting roller 62 are rotatably connected to the guide block 64. A guide groove 12 is provided on the frame 1, and the guide block 64 is slidably connected to the guide groove 12. The push rod 63 is fixedly connected to the frame 1. The push rods 63 are arranged staggeredly in the guide groove 12, and the output end of the push rod 63 is drivingly connected to the guide block 64. The conveyor belt 41 is wound around the first adjusting roller 61 and the second adjusting roller 62 in an S shape.

[0054] The conveyor belt 41 wound around the first adjusting roller 61 and the second adjusting roller 62 in an S shape is in a tensioned state. When the driving roller 52 rotates at an accelerated speed, the push rod 63 contracts, driving the guide block 64 to move along the guide groove 12 to both sides, stretching the conveyor belt 41 wound around the first adjusting roller 61 and the second adjusting roller 62, and performing dynamic compensation on the conveyor belt 41 to prevent the conveyor belt 41 from breaking.

[0055] The working principle of the present invention: When the automatic feeding device is working, the control system 3 starts the conveying system 4, and the materials in the hopper fall onto the conveying system 4 at a certain rate. After the materials stored in the hopper 2 fall onto the conveyor belt 41, they will gradually move towards the discharge port 11 under the drive of the conveyor belt 41 and finally fall into the incinerator for combustion; when the materials are transferred onto the conveyor belt 56, the detection assembly 57 is used to judge the weight of the materials. When the weight of the materials passing through the conveyor belt 56 is relatively light, the transmission mechanism 55 acts, and the movable assembly 555 acts, pushing the first movable sleeve 553 to move along the driving shaft 551 towards the driving wheel 556, and the second movable sleeve 554 to move along the driven shaft 552 away from the driven wheel 557. This makes the diameter of the transmission shaft formed by the sliders 558 on the driving wheel 556 larger, and the diameter of the transmission shaft formed by the sliders on the driven wheel 557 smaller. Since the rotational speed of the driving wheel 556 is fixed, under the drive of the transmission belt 559, the rotational speed of the driven wheel 557 is greater than that of the driving wheel 556, making the driving roller 52 and the power roller 51 rotate at a differential speed, which can correspondingly increase the rotational speed of the conveyor belt 41 wound around the driving roller 52, thereby increasing the moving speed of the materials on the conveyor belt 41, increasing the weight of the materials transferred onto the conveyor belt 56 per unit time, and realizing dynamic compensation for the weight of the materials. When the weight of the materials on the conveyor belt 56 is in the standard state, the transmission mechanism 55 acts to restore the rotational speeds of the power roller 51 and the driving roller 52 to be the same.
