Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and particularly relates to a crawler-type automatic feeding and stacking loading equipment. Background Art

[0002] At present, when stacking and loading materials (such as wood chips, etc.), a crawler-type stacker is mostly used to stack and load the wood chips. When the crawler-type stacker conveys and loads the wood chips, after the wood chips fall from the conveyor belt of the crawler-type stacker into the carriage, it will cause the sawdust and dust in the wood chips to fly, thus causing environmental pollution. At the same time, after the sawdust flies and falls on the ground, it needs to be cleaned by the staff. Therefore, a crawler-type automatic feeding and stacking loading equipment is proposed to facilitate filtering the flying sawdust and dust when stacking and loading the wood chips. Summary of the Invention

[0003] Aiming at the problems in the prior art, the present invention provides a crawler-type automatic feeding and stacking loading equipment, which is convenient for filtering the flying sawdust and dust when stacking and loading the wood chips.

[0004] The technical solution adopted by the present invention to solve its technical problems is a crawler-type automatic feeding and stacking loading equipment, including a main body. Both sides of the main body are provided with crawler wheels. An inclined conveying structure is arranged above the main body. The upper surface of the main body is fixedly connected with a support rod, and the upper end of the support rod is hinged to the conveying structure. A hydraulic telescopic rod is hinged to the upper surface of the main body, and the output ends of the hydraulic telescopic rods are all hinged to the lower surface of the conveying structure;

[0005] One end of the conveying structure is provided with an adjustable feeding structure. An adjustable filtering structure is arranged in the adjustable feeding structure. A driving structure is arranged outside the adjustable feeding structure, and the driving structure is used to drive the adjustable feeding structure. A detection structure is arranged below the adjustable feeding structure, and the detection structure is used to control the driving structure.

[0006] By adopting the above technical solution, when it is necessary to load the wood chips, the carriage of the vehicle is moved below the adjustable feeding structure, and at the same time, the wood chips are moved onto the conveying structure. The conveying structure is relied on to convey the wood chips. When the wood chips move to a certain position on the conveying structure, the wood chips fall into the adjustable feeding structure. As the wood chips move down, the wood chips fall into the carriage. Relying on the shielding of the adjustable feeding structure, the situation of dust flying during the stacking of the wood chips can be effectively reduced; and when the wood chips contact the carriage, the generated sawdust and dust and other impurities will move upward. At this time, the adjustable filtering structure is relied on to filter the sawdust and dust and other impurities, thereby further preventing the situation of sawdust and dust flying when stacking and loading the wood chips;

[0007] When the wood chips in the carriage are stacked to a certain position, as the wood chips continue to move downward, the wood chips will squeeze and contact the detection structure at this time. Rely on the detection structure to control the operation of the driving structure, and rely on the driving structure to drive the adjustable feeding structure to move upward, so as to prevent the problem that after the wood chips are stacked to a certain height, the wood chips are stacked in the adjustable feeding structure and cannot continue to fall and be transferred into the carriage. When the adjustable feeding structure moves upward to a certain position, the wood chips can continue to move downward through the adjustable feeding structure into the carriage, thereby further improving the convenience of stacking the wood chips;

[0008] When the adjustable feeding structure moves upward to the limit, the output end of the driving hydraulic telescopic rod extends, thereby driving the conveying structure to swing. When the conveying structure swings, it drives the adjustable feeding structure to move upward synchronously. When the adjustable feeding structure moves upward to a certain position, the wood chips can continue to move downward through the adjustable feeding structure into the carriage. At the same time, relying on the support rod can improve the overall stability of the conveying structure, so as to facilitate stacking and loading the wood chips according to the amount of wood chips in the carriage.

[0009] Specifically, the conveying structure includes two groups of mounting plates. Between the two groups of mounting plates, a number of conveying rollers are rotatably connected. Between the number of conveying rollers, they are driven by a conveyor belt. One end of one of the conveying rollers is connected with a driving motor, and the driving motor is fixedly connected with the mounting plate. Between the bottoms of the two groups of mounting plates, a support plate is fixedly connected. The upper end of the support rod is hinged to the lower surface of the support plate, and the output end of the hydraulic telescopic rod is hinged to the lower surface of the support plate.

[0010] By adopting the above technical solution, when it is necessary to load the wood chips, the wood chips are moved onto the conveyor belt. Rely on the driving motor to drive the conveying rollers to rotate. When the conveying rollers rotate, they drive the conveyor belt to move. Rely on the conveyor belt to convey the wood chips. When the wood chips move to a certain position on the conveyor belt, the wood chips enter the adjustable feeding structure, so as to facilitate the conveying and stacking and loading of the wood chips.

[0011] Specifically, a feeding frame is provided at the lower end of the conveying structure. The feeding frame is fixedly connected with the upper surfaces of the two groups of mounting plates. The adjustable feeding structure is located at one end of the mounting plate away from the feeding frame.

[0012] By adopting the above technical solution, the wood chips to be stacked and loaded are conveyed into the feeding frame. After the wood chips enter the feeding frame, they fall on the conveyor belt. Rely on the conveyor belt to convey the wood chips. At the same time, relying on the feeding frame can prevent the wood chips from spilling, so as to improve the stability during the conveying of the wood chips.

[0013] Specifically, the adjustable feeding structure includes a fixed frame. Symmetrically arranged connecting plates are fixedly connected to the outside of the fixed frame. The ends of the connecting plates away from the fixed frame are hinged to the outside of the mounting plate;

[0014] A sliding frame is slidably connected within the fixed frame. A chute is provided inside the fixed frame, and a slider corresponding to the chute is provided outside the sliding frame. The slider is located within the chute and is slidably connected to the chute. A driving structure is provided outside the fixed frame, and the driving structure is used to drive the sliding frame to move. The detection structure is located on the lower surface of the sliding frame, and the adjustable filtering structure is located within the fixed frame.

[0015] By adopting the above technical solution, when the wood chips move to a certain position on the conveyor belt, the wood chips sequentially enter the fixed frame and the sliding frame. As the wood chips move downward, the wood chips fall into the carriage. When the wood chips come into contact with the carriage, impurities such as wood chips and dust generated will move upward into the sliding frame and the fixed frame. At this time, the adjustable filtering structure is relied on to filter the wood chips and dust and other impurities, thereby preventing the situation of wood chips and dust flying when stacking and loading the wood chips.

[0016] When the wood chips in the carriage are stacked to a certain position, as the wood chips continue to move downward, the stacked wood chips will come into extrusion contact with the detection structure at this time. Rely on the detection structure to control the driving structure to work, and rely on the driving structure to drive the sliding frame to move upward. When the sliding frame moves upward to a certain position, at this time the wood chips can continue to fall into the carriage through the fixed frame and the sliding frame, thus facilitating the stacking and loading of the wood chips in height and facilitating the filtering of impurities such as wood chips and dust generated during the stacking of the wood chips.

[0017] When the driving structure drives the sliding frame to move upward, the cooperation between the slider and the chute can improve the movement stability of the sliding frame.

[0018] Specifically, the driving structure includes two groups of electric wire winders fixedly connected to the outside of the fixed frame. A pull rope is wound around the electric wire winder. Two groups of damping type guide wheels are provided at the top of the fixed frame, and the two groups of guide wheels respectively correspond to the two groups of electric wire winders. The end of the pull rope away from the electric wire winder extends downward after passing around the guide wheel and is fixedly connected to the upper surface of the sliding frame. The detection structure is used to control the electric wire winder.

[0019] By adopting the above technical solution, when the wood chips in the carriage are stacked to a certain position, as the wood chips continue to move downward, the stacked wood chips will come into extrusion contact with the detection structure at this time. Rely on the detection structure to control the electric wire winder to work, so as to wind and reel the pull rope. When one end of the pull rope is wound and reeled, it drives the guide wheel to rotate, and at the same time drives the sliding frame to move upward. When the sliding frame moves upward to a certain position, at this time the wood chips can continue to fall into the carriage through the fixed frame and the sliding frame, thus facilitating the stacking and loading of the wood chips in height.

[0020] After the sliding frame moves up to a certain position, the electric wire winder stops working, and the electric wire winder no longer winds and reels in the pulling rope. At this time, relying on the self-weight of the sliding frame, one end of the pulling rope is driven to move downward. When the pulling rope moves, it drives the guide wheel to rotate. Relying on the function of the damping type guide wheel, the moving speed of the pulling rope can be made slower, so that the sliding frame slowly moves downward, facilitating the stacking of wood chips;

[0021] After the sliding frame moves down to a certain position, relying on the detection structure to detect the stacked wood chips will drive the electric wire winder to work again, driving the sliding frame to move up, so as to facilitate the automatic adjustment of the position of the sliding frame and ensure the stacking effect of the wood chips;

[0022] It should be noted that the electric wire winder described in the present invention will automatically turn off the electric wire winder after winding and reeling in a certain length of the pulling rope.

[0023] Specifically, the detection structure includes a fixed rod fixedly connected to the lower surface of the sliding frame. The lower surface of the fixed rod is fixedly connected with a push switch, and the push switch is used to control the electric wire winder.

[0024] By adopting the above technical solution, when the wood chips in the carriage are stacked to a certain position, as the wood chips continue to move downward, at this time, the stacked wood chips will be in pressing contact with the push switch. Relying on the push switch to control the electric wire winder to work, the pulling rope is wound and reeled in, and the sliding frame is driven to move up, so as to facilitate automatically driving the sliding frame to move up according to the stacking height of the wood chips in the carriage, thereby effectively reducing the situation of dust flying during the current stacking process.

[0025] Specifically, the adjustable filtering structure includes several groups of first filter frames fixedly connected to the outside of the fixed frame. The several groups of first filter frames are evenly distributed in the vertical direction. The fixed frame is provided with several groups of first openings horizontally penetrating through, and the first openings are respectively communicated with the interiors of the several groups of first filter frames;

[0026] The upper inner side of the fixed frame is fixedly connected with a second filter frame. One side of the second filter frame is provided with several groups of second openings, and the second openings are communicated with the second filter frame. The outside of the fixed frame is fixedly connected with a negative pressure pump and an air filter. The air inlet of the negative pressure pump is communicated with the air filter, and the air filter is communicated with the first filter frame and the second filter frame through pipelines.

[0027] By adopting the above technical solution, when the wood chips move to a certain position on the conveyor belt, the wood chips enter the fixed frame and the sliding frame in sequence. As the wood chips move downward, the wood chips fall into the carriage. When the wood chips come into contact with the carriage, impurities such as wood chips and dust generated will move upward into the sliding frame and the fixed frame. At this time, relying on the suction force generated by the first openings and the second openings, the wood chips and dust and other impurities are suction filtered, so as to improve the convenience of loading the wood chips.

[0028] Specifically, a wedge-shaped cleaning block is fixedly connected to the upper surface of the sliding frame, and the wedge-shaped cleaning block is slidably connected to the inner wall of the fixed frame.

[0029] By adopting the above technical solution, when the wood chips are squeezed and contacted with the push switch, the push switch is used to control the electric winder to work, thereby winding and reeling the pull rope and driving the sliding frame to move upward. When the sliding frame moves upward, it is slidably connected with the fixed frame. At the same time, when the sliding frame moves upward, it drives the wedge-shaped cleaning block to move upward synchronously. When the wedge-shaped cleaning block moves upward, it slides and contacts with the inner wall of the fixed frame, and relies on the wedge-shaped cleaning block to clean the first opening in the fixed frame, thereby preventing wood chips from accumulating in the first opening and affecting the filtering effect.

[0030] As the sliding frame moves upward, the sliding frame blocks part of the first opening, and the length of the adjustable filter structure will decrease, thereby reducing the air exhaust volume in the filter structure and increasing the air exhaust force of the first opening, thereby ensuring the dust extraction effect of the first opening when the length of the filter structure is relatively small; conversely, as the sliding frame moves downward, the length of the adjustable filter structure increases, and the number of blocked first openings decreases, thereby increasing the air exhaust volume in the filter structure, thereby ensuring the air exhaust effect of the filter structure on the bottom of the sliding frame, and effectively reducing dust flying.

[0031] Specifically, a pressure detection switch is provided at the bottom of the second filter frame, and the upper surface of the wedge-shaped cleaning block is in squeeze contact with the lower surface of the pressure detection switch. The pressure detection switch is used to control the swing of the hydraulic telescopic rod.

[0032] By adopting the above technical solution, when the wood chips are piled up to a certain height, the sliding frame is driven upward by the electric winder. When the sliding frame moves up to a certain position, the wedge-shaped cleaning rod is squeezed into contact with the pressure detection switch, thereby driving the output end of the hydraulic telescopic rod to extend, and driving the fixed frame and the sliding frame to move up synchronously, thereby adjusting the angle of the conveyor belt and the height of the fixed frame and the sliding frame. When the fixed frame and the sliding frame move up to a certain position, the sliding frame moves down to the initial state. At the same time, the wood chips will continue to move down into the car through the fixed frame and the sliding frame to continue stacking the wood chips. In this way, the height of the fixed frame and the sliding frame can be automatically adjusted according to the stacking height of the wood chips, thereby further facilitating the stacking of the wood chips.

[0033] Beneficial effects of the present invention:

[0034] (1) For a crawler-type automatic loading and stacking equipment of the present invention, when the wood chips move to a certain position on the conveyor belt, the wood chips successively enter the fixed frame and the sliding frame. By relying on the shielding of the fixed frame and the sliding frame, the situation of dust flying during the stacking of wood chips can be effectively reduced. And when the wood chips come into contact with the carriage, the generated wood chips, dust and other impurities will move upward. By relying on the suction force generated by the first opening and the second opening, the wood chips, dust and other impurities are sucked and filtered, so as to further prevent the situation of wood chips and dust flying during the stacking and loading of wood chips.

[0035] (2) For a crawler-type automatic loading and stacking equipment of the present invention, when the wood chips in the carriage are stacked to a certain position and continue to move downward, the stacked wood chips will come into pressing contact with the pressing switch at this time. By relying on the pressing switch to control the operation of the electric wire winder, the pulling rope is wound and rolled up, and the sliding frame is driven to move upward, so as to facilitate automatically driving the sliding frame to move upward according to the height of the wood chips stacked in the carriage, thereby effectively reducing the situation of dust flying during the current stacking process.

[0045] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0046] In order to facilitate the filtration of flying wood chips and dust when stacking and loading wood chips onto a vehicle, as an embodiment of the present invention, as Figure 1 、 Figure 2 shown, a crawler-type automatic feeding and stacking loading device of the present invention includes a main body 1, crawler wheels 2 are provided on both sides of the main body 1, an inclined conveying structure is provided above the main body 1, a support rod 3 is fixedly connected to the upper surface of the main body 1, the upper end of the support rod 3 is hinged to the conveying structure, and a hydraulic telescopic rod 4 is hinged to the upper surface of the main body 1, and the output ends of the hydraulic telescopic rods 4 are respectively hinged to the lower surface of the conveying structure;

[0047] One end of the conveying structure is provided with an adjustable feeding structure, an adjustable filtering structure is arranged in the adjustable feeding structure, a driving structure is arranged outside the adjustable feeding structure, the driving structure is used to drive the adjustable feeding structure, and a detection structure is arranged below the adjustable feeding structure, and the detection structure is used to control the driving structure.

[0048] When in use, when it is necessary to load wood chips onto a vehicle, the carriage of the vehicle is moved below the adjustable feeding structure, and at the same time the wood chips are moved onto the conveying structure, and the wood chips are conveyed by relying on the conveying structure. When the wood chips move to a certain position on the conveying structure, the wood chips fall into the adjustable feeding structure, and as the wood chips move down, the wood chips fall into the carriage. Relying on the shielding of the adjustable feeding structure, the situation of dust flying during the stacking of wood chips can be effectively reduced; and when the wood chips contact the carriage, impurities such as wood chips and dust generated will move upward. At this time, the adjustable filtering structure is relied on to filter the wood chips and dust and other impurities, so as to further prevent the situation of wood chips and dust flying during the stacking and loading of wood chips;

[0049] When the wood chips in the carriage are piled up to a certain position, as the wood chips continue to move down, the wood chips will be squeezed and contacted with the detection structure, and the detection structure controls the operation of the driving structure, and the driving structure drives the adjustable feeding structure to move up, thereby preventing the problem that the wood chips cannot continue to fall and be transferred to the carriage after the wood chips are piled up to a certain height in the adjustable feeding structure. When the adjustable feeding structure moves up to a certain position, the wood chips can continue to move down into the carriage through the adjustable feeding structure, thereby further improving the convenience of stacking the wood chips.

[0050] When the adjustable feeding structure moves up to the limit, the output end of the hydraulic telescopic rod 4 is driven to extend, thereby driving the conveying structure to swing. When the conveying structure swings, the adjustable feeding structure is driven to move up synchronously. When the adjustable feeding structure moves up to a certain position, the wood chips can continue to move down into the carriage through the adjustable feeding structure. At the same time, the support rod 3 can improve the overall stability of the conveying structure, thereby facilitating the stacking and loading of wood chips according to the amount of wood chips in the carriage.

[0051] In order to facilitate the transportation of wood chips, for example, Figure 1 、 Figure 2 、 Figure 4 As shown, the present invention also includes that the conveying structure includes two groups of mounting plates 5, and several groups of conveying rollers 6 are rotatably connected between the two groups of mounting plates 5. The conveying rollers 6 are driven by conveyor belts 7, one end of one group of conveying rollers 6 is connected to a driving motor, and the driving motor is fixedly connected to the mounting plate 5. A support plate 8 is fixedly connected between the bottoms of the two groups of mounting plates 5, the upper end of the support rod 3 is hinged to the lower surface of the support plate 8, and the output end of the hydraulic telescopic rod 4 is hinged to the lower surface of the support plate 8.

[0052] During use, when wood chips need to be loaded onto a truck, the wood chips are moved onto the conveyor belt 7, and the conveyor roller 6 is driven to rotate by the driving motor. When the conveyor roller 6 rotates, the conveyor belt 7 is driven to move, and the wood chips are conveyed by the conveyor belt 7. When the wood chips move to a certain position on the conveyor belt 7, the wood chips enter the adjustable feeding structure, which facilitates the transportation and stacking of the wood chips for loading.

[0053] For example, Figure 1 As shown, the present invention also includes that a feed frame 9 is provided at the lower end of the conveying structure, and the feed frame 9 is fixedly connected to the upper surfaces of the two groups of mounting plates 5, and the adjustable feeding structure is located at the end of the mounting plate 5 away from the feed frame 9.

[0054] During use, the wood chips to be stacked and loaded are transported to the feed frame 9. After entering the feed frame 9, the wood chips fall onto the conveyor belt 7. The conveyor belt 7 is used to transport the wood chips. At the same time, the feed frame 9 can prevent the wood chips from falling, thereby improving the stability of the wood chips during transportation.

[0055] To prevent sawdust and dust from flying when stacking and loading wood chips, for example, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 shown, the present invention further includes that the adjustable feeding structure includes a fixed frame 10, symmetrically arranged connecting plates 11 are fixedly connected to the outside of the fixed frame 10, and one end of the connecting plate 11 away from the fixed frame 10 is hinged to the outside of the mounting plate 5;

[0056] A sliding frame 12 is slidably connected inside the fixed frame 10, a chute 13 is provided inside the fixed frame 10, a slider 14 corresponding to the chute 13 is provided on the outside of the sliding frame 12, the slider 14 is located in the chute 13 and is slidably connected to the chute 13, a driving structure is provided on the outside of the fixed frame 10, and the driving structure is used to drive the sliding frame 12 to move. The detection structure is located on the lower surface of the sliding frame 12, and the adjustable filtering structure is located inside the fixed frame 10.

[0057] During use, when the wood chips move to a certain position on the conveyor belt 7, the wood chips enter the fixed frame 10 and the sliding frame 12 in sequence. As the wood chips move down, the wood chips fall into the carriage. When the wood chips come into contact with the carriage, impurities such as sawdust and dust generated will move up into the sliding frame 12 and the fixed frame 10. At this time, the adjustable filtering structure is relied on to filter the sawdust and dust and other impurities, so as to prevent sawdust and dust from flying when stacking and loading wood chips;

[0058] When the wood chips in the carriage are stacked to a certain position, as the wood chips continue to move down, the stacked wood chips will come into extrusion contact with the detection structure at this time. The detection structure is relied on to control the driving structure to work, and the driving structure drives the sliding frame 12 to move up. When the sliding frame 12 moves up to a certain position, at this time the wood chips can continue to pass through the fixed frame 10 and the sliding frame 12 and fall into the carriage, so as to facilitate stacking and loading the wood chips and facilitate filtering of impurities such as sawdust and dust generated during wood chip stacking;

[0059] When the driving structure drives the sliding frame 12 to move up, the cooperation between the slider 14 and the chute 13 can be relied on to improve the moving stability of the sliding frame 12.

[0060] To facilitate driving the sliding frame 12 to move, for example, as Figure 2 , Figure 3 , Figure 5 , Figure 7As shown in the figure, the present invention further includes that the driving structure includes two groups of electric wire winders 15 fixedly connected to the outside of the fixed frame 10. A pull rope 16 is wound around the electric wire winder 15. Two groups of damping guide wheels 17 are provided at the top of the fixed frame 10. The two groups of guide wheels 17 correspond to the two groups of electric wire winders 15 respectively. The end of the pull rope 16 away from the electric wire winder 15 extends downward after passing around the guide wheel 17 and is fixedly connected to the upper surface of the sliding frame 12. The detection structure is used to control the electric wire winder 15.

[0061] During use, when the wood chips in the carriage are stacked to a certain position and then continue to move downward, the stacked wood chips will squeeze and contact the detection structure at this time. Relying on the detection structure to control the operation of the electric wire winder 15, the pull rope 16 is wound and retracted. When one end of the pull rope 16 is wound and retracted, it drives the guide wheel 17 to rotate, and at the same time drives the sliding frame 12 to move upward. When the sliding frame 12 moves upward to a certain position, the wood chips can continue to fall into the carriage through the fixed frame 10 and the sliding frame 12, so as to facilitate stacking and loading the wood chips.

[0062] When the sliding frame 12 moves upward to a certain position, the electric wire winder 15 stops working and no longer winds and retracts the pull rope 16. At this time, relying on the self-weight of the sliding frame 12 to drive one end of the pull rope 16 to move downward. When the pull rope 16 moves, it drives the guide wheel 17 to rotate. Relying on the function of the damping guide wheel 17, the moving speed of the pull rope 16 can be made slower, so that the sliding frame 12 moves downward slowly, which is convenient for stacking the wood chips.

[0063] When the sliding frame 12 moves downward to a certain position, relying on the detection structure to detect the stacked wood chips will drive the electric wire winder 15 to work again, driving the sliding frame 12 to move upward, so as to facilitate automatically adjusting the position of the sliding frame 12 and ensuring the stacking effect of the wood chips.

[0064] It should be noted that the electric wire winder 15 of the present invention will automatically turn off the electric wire winder 15 after winding and retracting the pull rope 16 by a certain length.

[0065] Exemplarily, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 As shown in the figure, the present invention further includes that the detection structure includes a fixed rod 18 fixedly connected to the lower surface of the sliding frame 12. A push switch 19 is fixedly connected to the lower surface of the fixed rod 18. The push switch 19 is used to control the electric wire winder 15.

[0066] During use, when the wood chips in the carriage are piled up to a certain position, as the wood chips continue to move downward, the piled wood chips will be squeezed and contacted with the press switch 19, and the electric winder 15 will be controlled by the press switch 19 to work, thereby winding the pull rope 16 and driving the sliding frame 12 to move upward, so that the sliding frame 12 can be automatically driven to move upward according to the height of the wood chips piled in the carriage, thereby effectively reducing the dust flying during the current stacking process.

[0067] In order to facilitate the suction and filtration of impurities such as sawdust and dust, for example, Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 As shown, the present invention also includes that the adjustable filtering structure includes a plurality of groups of first filter frames 20 fixedly connected to the outside of the fixed frame 10, the plurality of groups of first filter frames 20 are evenly distributed along the vertical direction, and the fixed frame 10 is provided with a plurality of groups of first openings 21 horizontally penetrating therethrough, the first openings 21 being respectively communicated with the interiors of the plurality of groups of first filter frames 20;

[0068] A second filter frame 22 is fixedly connected to the inner side of the upper part of the fixed frame 10. A plurality of second openings 23 are provided on one side of the second filter frame 22. The second openings 23 are communicated with the second filter frame 22. A negative pressure pump 24 and an air filter 25 are fixedly connected to the outer side of the fixed frame 10. The air inlet of the negative pressure pump 24 is communicated with the air filter 25. The air filter 25 is communicated with the first filter frame 20 and the second filter frame 22 respectively through pipelines.

[0069] During use, after the wood chips move to a certain position on the conveyor belt 7, the wood chips enter the fixed frame 10 and the sliding frame 12 in turn. As the wood chips move downward, the wood chips fall into the carriage. When the wood chips come into contact with the carriage, the wood chips, dust and other impurities generated move up and enter the sliding frame 12 and the fixed frame 10. At this time, the suction force generated by the first opening 21 and the second opening 23 is used to suck and filter the wood chips, dust and other impurities, thereby improving the convenience of loading the wood chips.

[0070] For example, Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, the present invention further includes a wedge-shaped cleaning block 26 fixedly connected to the upper surface of the sliding frame 12 , and the wedge-shaped cleaning block 26 is slidably connected to the inner wall of the fixed frame 10 .

[0071] During use, when the wood chips are pressed and contacted with the push switch 19, the push switch 19 is used to control the electric winder 15 to work, thereby winding and reeling the pull rope 16, and driving the sliding frame 12 to move upward. When the sliding frame 12 moves upward, it is slidably connected with the fixed frame 10. At the same time, when the sliding frame 12 moves upward, it drives the wedge-shaped cleaning block 26 to move upward synchronously. When the wedge-shaped cleaning block 26 moves upward, it slides and contacts with the inner wall of the fixed frame 10, and relies on the wedge-shaped cleaning block 26 to clean the first opening 21 in the fixed frame 10, thereby preventing wood chips from accumulating in the first opening 21 and affecting the filtering effect.

[0072] As the sliding frame 12 moves upward, the sliding frame 12 blocks part of the first opening 21, and the length of the adjustable filter structure will be reduced, thereby reducing the air extraction volume in the filter structure and increasing the air extraction force of the first opening 21, thereby ensuring the dust extraction effect of the first opening 21 when the length of the filter structure is small; conversely, as the sliding frame 12 moves downward, the length of the adjustable filter structure increases, and the number of the first openings 21 blocked is reduced, thereby increasing the air extraction volume in the filter structure, thereby ensuring the air extraction effect of the filter structure on the bottom of the sliding frame 12, and effectively reducing the flying of dust.

[0073] For example, Figure 7 As shown, the present invention also includes that a pressure detection switch 27 is provided at the bottom of the second filter frame 22, and the upper surface of the wedge-shaped cleaning block 26 is in squeeze contact with the lower surface of the pressure detection switch 27, and the pressure detection switch 27 is used to control the swing of the hydraulic telescopic rod 4.

[0074] During use, when the wood chips are piled up to a certain height, the electric winder 15 drives the sliding frame 12 to move up. When the sliding frame 12 moves up to a certain position, the wedge-shaped cleaning rod is squeezed and contacted with the pressure detection switch 27, thereby driving the output end of the hydraulic telescopic rod 4 to extend, and driving the fixed frame 10 and the sliding frame 12 to move up synchronously, thereby adjusting the angle of the conveyor belt 7 and the height of the fixed frame 10 and the sliding frame 12. When the fixed frame 10 and the sliding frame 12 move up to a certain position, the sliding frame 12 moves down to its initial state. At the same time, the wood chips will continue to move down into the car through the fixed frame 10 and the sliding frame 12 to continue stacking the wood chips. In this way, the height of the fixed frame 10 and the sliding frame 12 can be automatically adjusted according to the stacking height of the wood chips, thereby further facilitating the stacking of the wood chips.

[0075] When the present invention is in use, when it is necessary to load wood chips, the vehicle compartment is moved to the bottom of the sliding frame 12, the wood chips are moved to the conveyor belt 7 through the feed frame 9, and the conveyor roller 6 is driven by the driving motor to rotate. When the conveyor roller 6 rotates, the conveyor belt 7 is driven to move, and the wood chips are transported by the conveyor belt 7. When the wood chips move to a certain position on the conveyor belt 7, the wood chips enter the fixed frame 10 and the sliding frame 12 in turn. As the wood chips move downward, the wood chips fall into the compartment. Relying on the fixed frame 10 and the sliding frame 12, the dust flying when the wood chips are stacked can be effectively reduced.

[0076] When the wood chips come into contact with the carriage, the wood chips, dust and other impurities generated move upward and enter the sliding frame 12 and the fixed frame 10. The suction force generated by the first opening 21 and the second opening 23 is used to suck and filter the wood chips, dust and other impurities, thereby preventing wood chips and dust from flying when the wood chips are stacked and loaded onto the carriage.

[0077] When the wood chips in the carriage are piled up to a certain position, as the wood chips continue to move down, the piled wood chips will be squeezed and contacted with the press switch 19, and the electric winder 15 will be controlled by the press switch 19 to work, thereby winding and reeling the pull rope 16, and driving the sliding frame 12 to move up. When the sliding frame 12 moves up to a certain position, the wood chips can continue to fall into the carriage through the fixed frame 10 and the sliding frame 12, thereby preventing the problem that the wood chips cannot continue to fall and be transferred to the carriage after they have accumulated to a certain height. When the sliding frame 12 moves up to a certain position, the wood chips can continue to move down into the carriage through the sliding frame 12, thereby further improving the convenience of stacking the wood chips.

[0078] When the sliding frame 12 moves upward, it is slidably connected with the fixed frame 10. At the same time, the upward movement of the sliding frame 12 drives the wedge-shaped cleaning block 26 to move upward synchronously. When the wedge-shaped cleaning block 26 moves upward, it slides and contacts with the inner wall of the fixed frame 10, and relies on the wedge-shaped cleaning block 26 to clean the first opening 21 in the fixed frame 10, thereby preventing wood chips from accumulating in the first opening 21 and affecting the filtering effect.

[0079] When the sliding frame 12 moves up to a certain position, the electric winder 15 stops working and no longer winds and reels the pull rope 16. At this time, the weight of the sliding frame 12 drives one end of the pull rope 16 to move down. When the pull rope 16 moves, it drives the guide wheel 17 to rotate. The damping guide wheel 17 can slow down the movement of the pull rope 16, so that the sliding frame 12 moves down slowly, which is convenient for stacking wood chips.

[0080] When the sliding frame 12 moves down to a certain position, after the pressing switch 19 detects the piled-up wood chips, it will drive the electric wire winder 15 to work again, driving the sliding frame 12 to move up, so as to facilitate the automatic adjustment of the position of the sliding frame 12 and ensure the stacking effect of the wood chips;

[0081] As the sliding frame 12 moves up, the sliding frame 12 blocks some of the first openings 21, and the length of the adjustable filtering structure will decrease, thereby reducing the air extraction volume in the filtering structure and increasing the air extraction force of the first openings 21, so as to ensure the dust extraction effect of the first openings 21 when the length of the filtering structure is small; conversely, as the sliding frame 12 moves down, the length of the adjustable filtering structure increases, and the number of the first openings 21 blocked decreases, thereby increasing the air extraction volume in the filtering structure, so as to ensure the air extraction effect of the filtering structure on the bottom of the sliding frame 12 and effectively reduce the situation of dust flying;

[0082] When the wood chips are piled up to a certain height, the electric wire winder 15 drives the sliding frame 12 to move up. When the sliding frame 12 moves up to a certain position, the wedge-shaped cleaning rod squeezes and contacts the pressure detection switch 27, thereby driving the output end of the hydraulic telescopic rod 4 to extend, and driving the fixed frame 10 and the sliding frame 12 to move up synchronously, so as to adjust the angle of the conveyor belt 7 and the heights of the fixed frame 10 and the sliding frame 12. When the fixed frame 10 and the sliding frame 12 move up to a certain position, at this time the sliding frame 12 moves down to the initial state, and at the same time the wood chips will continue to pass through the fixed frame 10 and the sliding frame 12 and move down into the carriage to continue the stacking work of the wood chips. In this way, the heights of the fixed frame 10 and the sliding frame 12 can be automatically adjusted according to the stacking height of the wood chips, so as to further facilitate the stacking and loading of the wood chips.
