Description

Technical Field

[0001] The invention relates to the technical field of material conveying, in particular to automatic feeding equipment for an incinerator. Background Art

[0002] Automatic feeding equipment for incinerators is usually designed to effectively transport solid waste or biomass fuel into the combustion chamber for incineration. Automatic feeding equipment can not only improve the efficiency and safety of the incinerator, but also reduce the need for manual operation and reduce operating costs. These devices are mainly composed of the following parts: 1. Hopper: used to store and pre-process waste or biomass.

[0003] 2. Conveying system: conveys the material in the hopper to the combustion chamber. This usually includes a chain conveyor, screw conveyor or other types of conveying equipment, the specific choice depends on the nature of the waste and the design of the combustion furnace.

[0004] 3. Feed control system: used to monitor and adjust the feed rate and quantity of materials to ensure that the burner can maintain stable combustion conditions.

[0005] However, when the existing feeding equipment is in use, the flow rate of the hopper when discharging the material is uneven, which makes the flow rate of the fuel entering the incinerator uneven, and easily leads to unstable combustion of the fuel in the incinerator. Summary of the invention

[0006] The object of the present invention is to provide an automatic feeding device for an incinerator to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: the automatic feeding equipment includes a frame, a hopper, a control system, a conveying system and an adjustment system. The hopper is tightly connected to the frame, the control system is tightly connected to the frame, the control system is electrically connected to the conveying system and the adjustment system, the conveying system is tightly connected to the frame, the adjustment system is tightly connected to the frame, the adjustment system is used to adjust the distribution state of the material, and a discharge port is provided on the side of the frame away from the hopper.

[0008] The rack is placed on the ground to provide stable support for each system. The hopper is used to store materials and input the materials into the conveying system. When the automatic feeding equipment is working, the control system starts the conveying system, and the materials in the hopper fall into the conveying system at a certain rate. Then the conveying system transports the materials to the discharge port and enters the incinerator for combustion. At the same time, in order to ensure the stability of the flow rate of the conveying system when conveying materials, the material passing through the conveying system is adjusted in real time through the adjustment system to make its distribution uniform, so as to ensure the stable combustion of the materials entering the incinerator.

[0009] Furthermore, 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 firmly connected to the frame, the output end of the driving motor is transmission-connected to the driving roller, the conveyor belt is wound around the driving roller and the redirecting roller, a number of redirecting rollers are arranged along the movement direction of the conveyor belt, and the driving motor is electrically connected to the control system.

[0010] The drive motor is the main power source of the conveying system, and the control system is used to control the opening and closing of the drive motor. Driven by the drive motor, the drive roller rotates around the frame, thereby driving the conveyor belt wound around the drive roller and the redirecting roller to move. After the material stored in the hopper falls onto the conveyor belt, it will gradually move toward the discharge port driven by the conveyor belt and finally fall into the incinerator for combustion.

[0011] Furthermore, the adjustment system includes a power roller, a transmission roller, a guide roller, an adjustment motor, a transmission mechanism, a transfer belt and a detection component. The power roller and the transmission roller are rotatably connected to the frame, the transfer belt is wound around the power roller and the guide roller, the transmission roller is transmission-connected to the conveyor belt, the adjustment motor is tightly connected to the frame, the output end of the adjustment motor is transmission-connected to the transmission mechanism, the transmission mechanism is respectively transmission-connected to the power roller and the transmission roller, the detection component is tightly connected to the frame, and the detection component is used to measure the weight of the material passing through the transfer belt.

[0012] The material dropped from the hopper onto the conveyor belt will have uneven weight, with some sections being light and some being heavy. The material on the conveyor belt can be redistributed through the adjustment system, and the heavy part can be transferred to the light area, so as to achieve dynamic compensation of the material on the conveyor belt, so that the distribution of the material on the conveyor belt tends to be uniform, thereby ensuring that the weight of the material entering the incinerator remains uniform, thereby improving the combustion stability of the incinerator; when the material on the conveyor belt moves to the transfer belt, the adjustment motor is used to drive the power roller, thereby driving the transfer belt to move along the guide roller. A corresponding guide plate is provided between the conveyor belt and the transfer belt. Under the action of inertia, the material will be transferred from the conveyor belt along the guide plate to the transfer belt, and the transfer belt and The rotation speed of the conveyor belt is consistent to ensure the stability of transfer; in the initial state, the rotation speed of the power roller and the transmission roller is consistent. When 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 light, the transmission mechanism is activated to increase the rotation speed transmitted to the transmission roller, so that the transmission roller and the power roller can achieve differential rotation. The increase in the rotation speed of the transmission roller can correspondingly increase the rotation speed of the conveyor belt wound around the transmission roller, 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, and realizing dynamic compensation of the material weight. When the weight of the material on the conveyor belt is in a standard state, the transmission mechanism is activated to restore the rotation speed of the power roller and the transmission roller to be consistent.

[0013] Furthermore, the transmission mechanism includes a driving shaft, a driven shaft, a first movable sleeve, a second movable sleeve, a movable assembly, a driving wheel, a driven wheel and a slider. One end of the driving shaft is drivingly connected to the output end of the adjusting motor, the other end of the driving shaft is drivingly connected to the power roller, one end of the driven shaft is rotationally connected to the frame, the other end of the driven shaft is drivingly connected to the transmission roller, the driving wheel is tightly connected to the driving shaft, the driven wheel is tightly connected to the driven shaft, the first movable sleeve is slidingly connected to the driving shaft, the second movable sleeve is slidingly connected to the driven shaft, one end of the movable assembly is hinged to the first movable sleeve, the other end of the movable assembly is hinged to the second movable sleeve, a number of sliding grooves are provided on the driving wheel and the driven wheel, the slider is slidingly connected to the sliding groove, a transmission belt is sleeved on the slider, and the slider is respectively hinged to the first movable sleeve and the second movable sleeve through connecting rods.

[0014] The regulating motor transmits torque to the driving shaft, thereby driving the driving shaft to rotate at a fixed speed, and then driving the power roller to rotate at a certain speed. In the initial state, the diameter of the transmission shaft composed of sliders in several slide grooves on the driving wheel and the driven wheel is the same. Driven by the transmission belt wound around the slider, the rotation speeds of the power roller and the transmission roller are kept consistent. When the rotation speed of the transmission roller needs to be increased, the movable component is actuated to push the first movable sleeve along the driving shaft toward the driving wheel, and the second movable sleeve moves along the driven shaft away from the driven wheel, which increases the diameter of the transmission shaft composed of the sliders on the driving wheel and reduces the diameter of the transmission shaft composed of the sliders on the driven wheel. The rotation speed of the driving wheel is fixed. Under the transmission of the transmission belt, the rotation speed of the driven wheel is greater than that of the driving wheel, which causes the transmission roller and the power roller to form a differential rotation.

[0015] Furthermore, the detection component includes a support plate, which is fastened to the frame, and a pressure strain gauge is provided on the support plate. The detection end of the pressure strain gauge abuts against the transmission belt, and the pressure strain gauge is electrically connected to the movable component.

[0016] When the material is transferred to the conveyor belt, the material's own gravity will press the conveyor belt onto the pressure strain gauge on the support plate. Under the action of the material's gravity, the pressure strain gauge will be stretched, causing the resistance of the pressure strain gauge to increase. The pressure strain gauge is connected to an external power supply, so that the current transmitted to the active component will decrease accordingly. The smaller the weight of the material on the conveyor belt, the smaller the resistance of the pressure strain gauge, and the greater the current transmitted to the active component.

[0017] 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.

[0018] 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.

[0019] Furthermore, the automatic feeding device also includes a tightening mechanism, which is used to adjust the tightness of the conveyor belt.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the material is transferred to the conveyor belt, the detection component is used to determine the weight of the material. When the weight of the material passing through the conveyor belt is relatively light, the transmission mechanism is activated to increase the rotation speed transmitted to the transmission roller, so that the transmission roller and the power roller can achieve differential rotation. The increase in the rotation speed of the transmission roller can correspondingly increase the rotation speed of the conveyor belt wound around the transmission roller, 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, realizing dynamic compensation for the material weight, and improving the uniformity of transportation.

[0024] 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. Because the opposite ends of the rack and the electromagnet are provided with repelling magnets, under the effect of opposite charges attracting each other, the rack is driven to move toward the electromagnet, 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.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a technical solution: like Figure 1 As shown, the automatic feeding equipment includes a frame 1, a hopper 2, a control system 3, a conveying system 4 and an adjusting system 5. The hopper 2 is tightly connected to the frame 1, the control system 3 is tightly 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 tightly connected to the frame 1, the adjusting system 5 is tightly connected to the frame 1, the adjusting system 5 is used to adjust the distribution state of the material, and a discharge port 11 is provided on the side of the frame 1 away from the hopper 2.

[0028] The frame 1 is placed on the ground to provide stable support for each system. The hopper 2 is used to store materials and input the materials into the conveying system 4. When the automatic feeding equipment is working, the control system 3 starts the conveying system 4, and the materials in the hopper fall into the conveying system 4 at a certain rate. Then the conveying system 4 conveys the materials to the discharge port 11 and enters the incinerator for combustion. At the same time, in order to ensure the stability of the flow rate of the conveying system 4 when conveying materials, the adjustment system 5 is used to adjust the materials passing through the conveying system 4 in real time to make its distribution uniform, so as to ensure the stable combustion of the materials entering the incinerator.

[0029] like Figure 2As 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 tightly connected to the frame 1, and the output end of the driving motor 43 is transmission-connected to the driving roller 42. The conveyor belt 41 is wound around the driving roller 42 and the redirecting roller 44. Several redirecting rollers 44 are arranged along the moving direction of the conveyor belt 41, and the driving motor 43 is electrically connected to the control system 3.

[0030] The driving motor 43 is the main power source of the conveying system 4, and 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 material stored in the hopper 2 falls onto the conveyor belt 41, it will gradually move toward the discharge port 11 driven by the conveyor belt 41, and finally fall into the incinerator for combustion.

[0031] like Figure 3-7 As shown, the adjustment system 5 includes a power roller 51, a transmission roller 52, a guide roller 53, an adjustment motor 54, a transmission mechanism 55, a transfer belt 56 and a detection component 57. The power roller 51 and the transmission roller 52 are rotatably connected to the frame 1. The transfer belt 56 is wound around the power roller 51 and the guide roller 53. The transmission roller 52 is transmission-connected to the conveyor belt 41. The adjustment motor 54 is tightly connected to the frame 1. The output end of the adjustment motor 54 is transmission-connected to the transmission mechanism 55. The transmission mechanism 55 is transmission-connected to the power roller 51 and the transmission roller 52 respectively. The detection component 57 is tightly connected to the frame 1. The detection component 57 is used to measure the weight of the material passing through the transfer belt 56.

[0032] The material dropped from the hopper 2 onto the conveyor belt 41 will have uneven weight, with one section being light and the other being heavy. The material on the conveyor belt 41 is redistributed through the adjustment system 5, and the heavy part is transferred to the light area, so as to achieve dynamic compensation of the material on the conveyor belt 41, so that the distribution of the material on the conveyor belt 41 tends to be uniform, thereby ensuring that the weight of the material entering the incinerator remains uniform, thereby improving the combustion stability of the incinerator; when the material on the conveyor belt 41 moves to the transfer belt 56, the adjustment motor 54 is used to drive the power roller 51, thereby driving the transfer belt 56 to move along the guide roller 53, and a corresponding guide plate is provided between the conveyor belt 41 and the transfer belt 56. Under the action of inertia, the material will be transferred from the conveyor belt 41 along the guide plate to the transfer belt 56, and the transfer belt 56 and the conveyor belt 41 has the same rotation speed, thereby ensuring the stability of transportation; in the initial state, the rotation speed of the power roller 51 and the transmission roller 52 is consistent. When the material is transferred to the transmission belt 56, the detection component 57 is used to judge the weight of the material. When the weight of the material passing through the transmission belt 56 is light, the transmission mechanism 55 is activated to increase the rotation speed transmitted to the transmission roller 52, so that the transmission roller 52 and the power roller 51 can realize differential rotation. The increase in the rotation speed of the transmission roller 52 can correspondingly increase the rotation speed of the conveyor belt 41 wound around the transmission roller 52, thereby increasing the moving speed of the material on the conveyor belt 41, and increasing the weight of the material transferred to the transmission belt 56 per unit time, thereby realizing dynamic compensation of the material weight. When the weight of the material on the transmission belt 56 is in a standard state, the transmission mechanism 55 is activated to restore the rotation speed of the power roller 51 and the transmission roller 52 to be consistent.

[0033] like Figure 3-7 As 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 assembly 555, a driving wheel 556, a driven wheel 557 and a slider 558. One end of the driving shaft 551 is drivingly connected to the output end of the adjusting motor 54, the other end of the driving shaft 551 is drivingly connected to the power roller 51, one end of the driven shaft 552 is rotatably connected to the frame 1, the other end of the driven shaft 552 is drivingly connected to the transmission roller 52, the driving wheel 556 is tightly connected to the driving shaft 551, and the driven wheel 557 is connected to the driving roller 52. It is tightly connected to the driven shaft 552, the first movable sleeve 553 is slidably connected to the driving shaft 551, 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 sliding grooves are provided on the driving wheel 556 and the driven wheel 557, the slider 558 is slidably connected to the sliding grooves, the slider 558 is provided with a transmission belt 559, and the slider 558 is respectively hinged to the first movable sleeve 553 and the second movable sleeve 554 through a connecting rod.

[0034] The regulating motor 54 transmits the torque to the driving shaft 551, thereby driving the driving shaft 551 to rotate at a fixed speed, and then 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 the plurality of slide grooves on the driving wheel 556 and the driven wheel 557 is the same. Driven by the transmission belt 559 wound around the slider 558, the rotation speeds of the power roller 51 and the transmission roller 52 are kept consistent. When the rotation speed of the transmission roller 52 needs to be increased, the movable component 555 is actuated to push the first The movable sleeve 553 moves along the driving shaft 551 toward the driving wheel 556, and the second movable sleeve 554 moves along the driven shaft 552 away from the driven wheel 557, so that the diameter of the transmission shaft composed of the sliders 558 on the driving wheel 556 becomes larger, and the diameter of the transmission shaft composed of the sliders on the driven wheel 557 becomes smaller. The rotation speed of the driving wheel 556 is fixed. Under the drive of the transmission belt 559, the rotation speed of the driven wheel 557 is greater than the rotation speed of the driving wheel 556, so that the transmission roller 52 and the power roller 51 form a differential rotation.

[0035] like Figure 4 As shown, the detection component 57 includes a support plate 571, which is fastened 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 transmission belt 56, and the pressure strain gauge 572 is electrically connected to the movable component 555.

[0036] When the material is transferred to the conveyor belt 56, the material's own gravity will press the conveyor belt 56 against the pressure strain gauge 572 on the support plate 571. Under the gravity of the material, the pressure strain gauge 572 will be stretched, causing the resistance of the pressure strain gauge 572 to increase. The pressure strain gauge 572 is connected to an external power supply, so that the current transmitted to the movable component 555 will decrease accordingly. The smaller the weight of the material on the conveyor belt 56, the smaller the resistance of the pressure strain gauge 572, and the greater the current transmitted to the movable component 555.

[0037] like Figure 5-7As shown, the movable assembly 555 includes a connecting seat 5551, a telescopic rod 5552, a gear 5553, a rack 5554, a reset spring 5555 and an electromagnet 5556. The connecting seat 5551 is fastened 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, and the gear 5553 is located in the transmission cavity. The gear 5553 is fastened to the telescopic rod 5552, the gear 5553 is rotatably connected to the connecting seat 5551, and the rack 5554 is rotatably connected to the connecting seat 5551. It is slidingly connected to the transmission chamber, the rack 5554 is meshed with the gear 5553, one end of the reset spring 5555 is tightly connected to the rack 5554, the other end of the reset spring 5555 is tightly connected to the inner wall of the transmission chamber, the electromagnet 5556 is tightly connected to the connecting seat 5551, the electromagnet 5556 is located in the transmission chamber away from the end of the reset spring 5555, the rack 5554 and the electromagnet 5556 are provided with a repelling magnet 5557 at the facing ends, the repelling magnet 5557 and the facing ends of the electromagnet 5556 are opposite poles, and the electromagnet 5556 is electrically connected to the pressure strain gauge 572.

[0038] 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 retracted state. When the weight of the material on the conveyor belt 56 is 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. Because the opposite ends of the rack 5554 and the electromagnet 5556 are provided with repelling magnets 5557, under the effect of opposites attracting each other, the rack 5554 is driven to move toward the electromagnet 5556, and the reset is performed. The spring 5555 is stretched under force, thereby driving the gear 5553 to rotate, and then driving the telescopic rod 5552 to rotate and extend along the connecting seat 5551. Driven by the telescopic rod 5552, the first movable sleeve 553 and the second movable sleeve 554 slide along the driving shaft 551 and the driven shaft 552 respectively, so that the slider 558 on the driving wheel 556 expands outward and the slider 558 on the driven wheel 557 contracts inward, thereby 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.

[0039] like Figure 8-9 As shown, the automatic feeding device further includes a tightening mechanism 6 , which is used to adjust the tightness of the conveyor belt 41 .

[0040] 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 by the tightening mechanism 6 to dynamically compensate the conveyor belt 41 .

[0041] like Figure 8-9As shown, 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. The guide block 64 is slidably connected to the guide groove 12. The push rod 63 is tightly connected to the frame 1. The push rod 63 is staggered in the guide groove 12. The output end of the push rod 63 is transmission-connected to the guide block 64. The conveyor belt 41 is S-shaped and wound around the first adjusting roller 61 and the second adjusting roller 62.

[0042] The conveyor belt 41 wound in an S shape on the first adjusting roller 61 and the second adjusting roller 62 is in a taut state. When the driving roller 52 accelerates, the push rod 63 contracts, driving the guide block 64 to move to both sides along the guide groove 12, stretching the conveyor belt 41 wound on the first adjusting roller 61 and the second adjusting roller 62, dynamically compensating the conveyor belt 41, and preventing the conveyor belt 41 from breaking.

[0043] The working principle of the present invention is as follows: when the automatic feeding equipment 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. After the material stored in the hopper 2 falls onto the conveyor belt 41, it will gradually move toward the discharge port 11 driven by the conveyor belt 41, and finally fall into the incinerator for combustion; when the material is transferred to the conveyor belt 56, the detection component 57 is used to judge the weight of the material. When the weight of the material passing through the conveyor belt 56 is light, the transmission mechanism 55 is actuated, and the movable component 555 is actuated to push the first movable sleeve 553 to move along the driving shaft 551 toward the driving wheel 556, and the second movable sleeve 554 moves along the driven shaft 552 away from the driven wheel 557, so that the driving wheel The diameter of the transmission shaft composed of the sliders 558 on 556 becomes larger, and the diameter of the transmission shaft composed of the sliders on the driven wheel 557 becomes smaller, while the rotation speed of the driving wheel 556 is fixed. Under the transmission of the transmission belt 559, the rotation speed of the driven wheel 557 is greater than the rotation speed of the driving wheel 556, so that the transmission roller 52 and the power roller 51 form a differential rotation, which can correspondingly increase the rotation speed of the conveyor belt 41 wound around the transmission roller 52, thereby increasing the moving speed of the material on the conveyor belt 41, and increasing the weight of the material transported to the transfer belt 56 per unit time, thereby realizing dynamic compensation of the material weight. When the weight of the material on the transfer belt 56 is in a standard state, the transmission mechanism 55 is actuated to restore the rotation speeds of the power roller 51 and the transmission roller 52 to be consistent.
