Description

Technical Field

[0001] This invention relates to the field of litter collection equipment, and more specifically to a litter collection device for measuring forestry carbon sequestration. Background Technology

[0002] The litter collection equipment used in forestry carbon sequestration is a technical device specifically designed for the precise collection and quantification of forest litter biomass. Its core function is to provide reliable data support for carbon storage accounting through a scientific collection and processing process. In existing forestry carbon sequestration litter collection equipment, workers place the equipment with its opening facing upwards on the ground to naturally collect litter. The equipment is then cleaned regularly, and the accumulated litter is sorted. Finally, the sorted litter is taken back to the laboratory, dried to remove moisture, and weighed to obtain data on the yield of different types of litter per unit area. This provides fundamental support for assessing the carbon storage and dynamic changes in the forest litter pool.

[0003] A search revealed that while some existing patents have improved the screening structure of litter, they still fail to overcome the problems of insufficient classification accuracy and efficiency for lightweight litter. For example, Chinese patent (CN117483386A) discloses a litter collection device for forestry carbon sequestration, which uses a screening drum to classify litter. Although this solution can classify litter, it uses a single mechanical structure and does not involve pneumatic screening, resulting in limited effectiveness in classifying small or lightweight litter. Another example is a litter processing device disclosed in Chinese patent (CN216441062U), which uses a filter component to dry screen the litter and then further processes impurities. However, it lacks a clear classification mechanism and may only achieve mixed storage of litter, failing to meet the accuracy requirements of carbon sequestration for classifying litter based on its decomposition degree.

[0004] In summary, the main drawback of the above-mentioned solutions is that they only meet the preliminary screening requirements for litter, failing to overcome the limitation of insufficient classification accuracy and efficiency for lightweight litter. This results in suboptimal screening performance of the equipment during use. Therefore, the applicant has invented a litter collection device for forestry carbon sequestration measurement that can simultaneously perform pneumatic and mechanical screening of litter, while also reducing clogging during the screening process. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a litter collection device for forestry carbon sequestration metering. This device uses a drive assembly to operate an air supply assembly, which in turn supplies air into a vibrating cylinder. Through vibrating blocks, vibrating rods, and pressure relief holes, the screening plate undergoes periodic vibration, achieving high-frequency vibration of the screening plate. This reduces screen clogging while improving the screening rate for fine particles such as humus. Furthermore, the air supply assembly and the screening plate work synergistically to perform both mechanical and pneumatic screening of the litter, improving screening efficiency and quality.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A forestry carbon sequestration metering litter collection device includes a controller and a processing box. A handle is fixedly connected to the processing box. A feed inlet is opened at the top of the processing box. A guide frame is detachably connected to the feed inlet. A drive box and a first collection box are detachably connected to one side of the processing box. A through hole is opened on one side of the first collection box, and the first collection box communicates with the processing box through the through hole. A second collection box is detachably connected and communicates with the side of the processing box away from the drive box. A screening plate is hinged to the inner side wall of the processing box. The screening plate is located below the feed inlet. A screen is fixedly connected to the screening plate. A shaking rod is hinged to the bottom of the screening plate. A shaking cylinder is fixedly connected to the bottom wall of the processing box. The end of the shaking rod away from the screening plate extends into the shaking cylinder and is hinged to a shaking block. The shaking block slides vertically with the inner side wall of the shaking cylinder. A pressure relief hole is opened at the upper part of the side wall of the shaking cylinder.

[0007] The drive box contains a sorting component for classifying fallen materials, an air supply component for supplying gas to the lower part of the shaking cylinder, and a drive component for driving the air supply component. The controller is used to control the operation of the drive component.

[0008] The technical principles of the above solution are as follows: After determining the installation location of the debris collection equipment, the staff installs it in the designated position and selects the specifications of the guide frame according to the actual situation. Then, the controller operates the drive component, which in turn drives the air supply component to inflate the lower part of the shaking cylinder. As the gas continuously enters the shaking cylinder, it sequentially moves the shaking block and shaking rod upward. When the shaking block is raised above the pressure relief hole, the gas inside the shaking cylinder escapes through the pressure relief hole. At this point, the shaking block and shaking rod can move downward under their own weight. The shaking rod drives the screening plate to swing up and down repeatedly, achieving a shaking effect and shaking and screening the debris on the screening plate.

[0009] The above approach has the following beneficial effects: 1. This invention drives an air supply component to operate, which in turn supplies air into the vibrating cylinder. Through the vibrating blocks, vibrating rods, and pressure relief holes, the screening plate vibrates periodically, achieving high-frequency vibration of the screening plate. This reduces screen clogging while improving the screening rate for fine particles such as humus. Simultaneously, the air supply component and the screening plate work together to perform both mechanical and pneumatic screening of fallen materials, improving screening efficiency and quality.

[0010] 2. This invention separates litter by designing a classification component, which enables the sieved litter to be automatically diverted, reducing the error in carbon content calculation caused by mixed storage of litter.

[0011] 3. By detachably connecting the guide frame to the processing box, the present invention allows staff to select guide frames of different specifications according to actual needs, thereby increasing the flexibility of the equipment.

[0012] Furthermore, the drive assembly includes a drive component fixedly connected to the inner wall of the drive housing, a controller for controlling the opening and closing of the drive component, a drive rod fixedly connected coaxially to the output shaft of the drive component, a half gear fixedly connected to the end of the drive rod away from the output shaft of the drive component, a drive frame provided inside the drive housing, racks fixedly connected to the inner top and inner bottom walls of the drive frame, and the racks meshing with the half gears; several limiting rods fixedly connected to the inner wall of the drive housing, and the two ends of the drive frame respectively pass through the adjacent limiting rods and slide laterally with the limiting rods.

[0013] Beneficial effects: During rotation, the half gear will mesh with the racks at the top and bottom of the drive frame in sequence, thereby driving the drive frame to reciprocate horizontally through the meshing of the gears and racks, improving the power transmission efficiency and making the equipment more efficient in screening fallen materials.

[0014] Furthermore, the drive assembly includes a drive component fixedly connected to the inner wall of the drive housing, a controller for controlling the opening and closing of the drive component, a drive rod fixedly connected coaxially to the output shaft of the drive component, a cam fixedly connected eccentrically to the end of the drive rod away from the output shaft of the drive component, a drive plate provided inside the drive housing, a drive groove opened on the drive plate for the output shaft of the drive component to pass through, transmission blocks symmetrically fixedly connected to one side of the drive plate, and the transmission blocks are all located in the motion path of the cam; several limit rods are fixedly connected to the inner wall of the drive housing, and the two ends of the drive plate respectively pass through the adjacent limit rods and slide laterally with the limit rods.

[0015] Beneficial effects: When the cam rotates, its contour curve will come into contact with the transmission block, pushing the transmission block and drive rod to reciprocate laterally. At the same time, it drives the sorting component and the air supply component to operate. The air supply component drives the shaking block and shaking rod to reciprocate up and down to simulate the rhythm of manual screening, thereby improving the screening efficiency of fallen materials.

[0016] Furthermore, the drive assembly includes a telescopic component fixedly connected to the inner wall of the processing box. A controller is used to control the opening and closing of the telescopic component. The output shaft of the telescopic component extends through the air supply assembly and is coaxially fixedly connected to a rack on one side of the air supply assembly. A rotating rod is rotatably engaged on the inner wall of the drive box. A full gear is fixedly connected to the rotating rod, and the full gear meshes with the rack. The sorting component is located at the end of the rotating rod away from the inner wall of the drive box. Several limiting rods are fixedly connected to the inner wall of the drive box. The rack passes through all the limiting rods and is laterally slidingly engaged with the limiting rods.

[0017] Beneficial effects: The design of using the output shaft of the telescopic component to drive the rack in linear motion, and then using the rack and gears to directly drive the sorting components, improves the stability of the transmission. This ensures that the rotational force of the gears can stably act on the sorting and air supply components, thus ensuring the accuracy of litter sorting.

[0018] Furthermore, the air supply assembly includes an air supply box fixedly connected to the inner side wall of the drive box. An air supply plate is laterally slidably fitted on the inner side wall of the air supply box. One end of the drive frame extends through the side wall of the air supply box and into the air supply box, where it is fixedly connected to the air supply plate. An inlet one-way valve and an outlet pipe are connected to the air supply box. An outlet one-way valve is connected at the connection between the outlet pipe and the air supply box. The end of the outlet pipe away from the air supply box extends through the side wall of the drive box and the side wall of the processing box and into the processing box, where it is connected to the lower part of the shaking cylinder.

[0019] Beneficial effects: When the drive frame drives the air supply plate to reciprocate, the air supply plate continuously delivers gas to the inside of the shaking cylinder. The gas drives the shaking block and shaking rod to move upward. When the shaking block moves upward to above the pressure relief hole, the airflow can escape from the pressure relief hole, thereby causing the shaking block and shaking rod to move downward under their own gravity. The shaking rod drives one end of the screening plate to shake up and down, improving the screening efficiency of fallen materials.

[0020] Furthermore, the sorting component includes a connecting rod that is coaxially and fixedly connected to the drive rod. Several fan blades are fixedly connected to the connecting rod. Air supply holes are opened on both the side wall of the drive box and the side wall of the processing box. The air supply holes are all located on the same straight line as the fan blades, and a dustproof net is fixedly connected to the air supply hole on the side wall of the processing box.

[0021] Beneficial effects: The high-speed rotating fan blades can form a directional airflow in the processing box, which can automatically separate light materials from heavy materials according to the density differences of different components of the fallen material, thereby achieving the effect of classifying the fallen material.

[0022] Furthermore, the first collection box is equipped with an auxiliary component for assisting the lowering of fallen debris. The auxiliary component includes an auxiliary plate. The end of the drive frame away from the air supply box extends through the side wall of the drive box and the side wall of the first collection box into the first collection box and is fixedly connected to the auxiliary plate. An inclined block is fixedly connected to the bottom wall of the first collection box, and an elastic block is fixedly connected to the bottom of the auxiliary plate. The inclined block is located in the movement path of the elastic block.

[0023] Beneficial effects: The design of the inclined block being located in the movement path of the elastic block allows the elastic block to push the fallen material on the inclined block when it is moved laterally by the auxiliary plate, thereby reducing the accumulation of fallen material and improving sorting efficiency.

[0024] Furthermore, guide blocks are fixedly connected to the screening plate.

[0025] Beneficial effects: When the fallen material moves on the screening plate, it can enter the first collection box through the through holes under the guidance of the guide block, which improves the continuity of fallen material transportation.

[0026] Furthermore, an arc-shaped plate is fixedly connected to the inner side wall of the second collection box.

[0027] Beneficial effects: When the fallen debris enters the second collection box, it can be transported to the bottom of the second collection box by the airflow. When the airflow re-enters the second collection box and disturbs the fallen debris inside, it can be guided by the arc plate, thereby reducing the possibility of the airflow escaping directly below the arc plate and causing the fallen debris to escape.

[0028] Furthermore, electric heating plates are fixedly connected to the inner bottom wall and inner side wall of both the first and second collection boxes, and the controller is used to control the opening and closing of the electric heating plates.

[0029] Beneficial effects: The design of fixing the heating plate to the inner bottom wall and inner side wall of the first and second collection boxes enables three-dimensional heating of the fallen material, which reduces the drying time of the fallen material compared with unidirectional heating.

[0030] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The following detailed description illustrates the specific implementation method: Example

[0037] As attached Figure 1 , Figure 2 and Figure 4 As shown: A litter collection device for forestry carbon sequestration measurement includes a controller and a processing box 1. The processing box 1 has an integrally formed handle. The top of the processing box 1 has a feed inlet, and a guide frame 2 is detachably connected to the feed inlet by screws. A drive box 3 and a first collection box 4 are detachably connected to one side of the processing box 1 by screws.

[0038] The first collection box 4 has a through hole on one side, and the first collection box 4 is connected to the processing box 1 through the through hole; the processing box 1 is detachably connected to the second collection box 5 on the side away from the drive box 3 by screws, and an arc plate 6 is welded on the inner wall of the second collection box 5.

[0039] Electric heating plates (not shown in the figure) are embedded in the inner bottom wall and inner side wall of the first collection box 4 and the second collection box 5. The controller is used to control the opening and closing of the electric heating plates.

[0040] like Figure 3 and Figure 5As shown, a screening plate 7 is hinged to the inner wall of the processing box 1. The screening plate 7 is located below the feed inlet. A screen mesh 8 is integrally formed on the screening plate 7, and a guide block 9 is welded to the screening plate 7. A shaking rod 10 is hinged to the bottom of the screening plate 7. A shaking cylinder 11 is welded to the bottom wall of the processing box 1. The end of the shaking rod 10 away from the screening plate 7 extends into the shaking cylinder 11 and is hinged to a shaking block 12. The shaking block 12 slides vertically with the inner wall of the shaking cylinder 11. A pressure relief hole is opened on the upper part of the side wall of the shaking cylinder 11.

[0041] like Figure 2 and Figure 6 As shown, the drive housing 3 contains a drive assembly, which includes a drive component fixedly connected to the inner wall of the drive housing 3 with screws. A controller is used to control the opening and closing of the drive component. A drive rod is fixedly connected to the output shaft of the drive component with coaxial screws. A half gear 14 is fixedly engaged at the end of the drive rod away from the output shaft of the drive component. The drive housing 3 contains a drive frame 15. The inner top wall and inner bottom wall of the drive frame 15 are integrally formed with racks 16, and the racks 16 mesh with the half gears 14. Several limiting rods 17 are welded to the inner wall of the drive housing 3. The two ends of the drive frame 15 pass through the adjacent limiting rods 17 and slide laterally with the limiting rods 17. In this embodiment, a stepper motor 32 is selected as the drive component.

[0042] Specifically, after determining the designated location for collecting fallen debris, the staff installs the collection equipment at the designated location and selects a guide frame 2 of the appropriate specification according to the collection requirements, installing it at the feed inlet. At this time, the fallen debris can enter the processing box 1 through the guide frame 2 and the feed inlet, falling onto the screening plate 7. Since the screen 8 is located on the screening plate 7, the fallen debris can be initially screened by the screen 8 when it falls onto the screening plate 7. At the same time, the fallen debris can also enter the first collection box 4 through the through hole under the guidance of the guide block 9.

[0043] The operator controls the output shaft of the stepper motor 32 to rotate via a controller, which in turn drives the half gear 14, which is fixedly engaged with it, to rotate via a drive rod. Since the rack 16 located on both the top and bottom walls of the drive frame 15 meshes with the half gear 14, the half gear 14 can drive the drive frame 15 to reciprocate laterally via the rack 16 during rotation. Figure 2 As shown, when the half gear 14 rotates clockwise and meshes with the rack 16 located on the inner top wall of the drive frame 15, it can drive the drive frame 15 to move to the right through the rack 16; when the half gear 14 meshes with the rack 16 located on the inner bottom wall of the drive frame 15, it can drive the drive frame 15 to move to the left through the rack 16.

[0044] The drive box 3 is equipped with an air supply assembly for supplying gas to the lower part of the vibrating cylinder 11.

[0045] like Figure 2 , Figure 6and Figure 7 As shown, the air supply assembly includes an air supply box 18 welded to the inner wall of the drive box 3. An air supply plate 19 is laterally slidably fitted onto the inner wall of the air supply box 18. One end of the drive frame 15 extends through the side wall of the air supply box 18 and is integrally formed with the air supply plate 19 inside the air supply box 18. An inlet one-way valve 20 and an outlet pipe 21 are connected to the air supply box 18. An outlet one-way valve 22 is connected at the connection between the outlet pipe 21 and the air supply box 18. The end of the outlet pipe 21 away from the air supply box 18 extends through the side wall of the drive box 3 and the side wall of the processing box 1 and is connected to the lower part of the shaking cylinder 11 inside the processing box 1. In this embodiment, the flow direction of the inlet one-way valve 20 is one-way from the outside of the air supply box 18 to the inside of the air supply box 18, and the flow direction of the outlet one-way valve 22 is one-way from the inside of the air supply box 18 to the inside of the outlet pipe 21.

[0046] Specifically, since the drive frame 15 and the air supply plate 19 are integrally formed, when the drive frame 15 reciprocates, it can drive the air supply plate 19 to slide laterally back and forth in the air supply box 18. The air outside the air supply box 18 is drawn into the air supply box 18 through the inlet one-way valve 20, and then the air in the air supply box 18 is transported to the lower part of the shaking cylinder 11 through the outlet one-way valve 22 and the outlet pipe 21 for inflation. At this time, since the inside of the shaking cylinder 11 is continuously inflated, the shaking block 12 will be lifted upward by the inflated air.

[0047] Since the two ends of the vibrating rod 10 are hinged to the vibrating block 12 and the screening plate 7 respectively, and the screening plate 7 is hinged to the inner wall of the processing box 1, when the vibrating block 12 is lifted by the gas, it can drive the vibrating rod 10 to move upward, and then drive the screening plate 7 to swing upward through the vibrating rod 10. When the vibrating block 12 is lifted above the pressure relief hole, the gas below the vibrating block 12 can escape from the pressure relief hole. At this time, the air pressure below the vibrating block 12 drops, and the vibrating block 12 can move downward under the action of the screening plate 7, the vibrating rod 10 and the gravity of the vibrating block 12 itself, thereby driving the vibrating rod 10 to move downward, and then driving the screening plate 7 to swing downward through the vibrating rod 10, so that the screening plate 7 vibrates periodically, which reduces the blockage of the screen 8 by the fallen material and improves the screening efficiency of the fallen material.

[0048] The drive box 3 is also equipped with a sorting component for classifying fallen debris.

[0049] like Figure 2 and Figure 6 As shown, the classification component includes a connecting rod integrally formed coaxially with the drive rod. Several fan blades 23 are integrally formed on the connecting rod. Air supply holes are opened on the side wall of the drive box 3 and the side wall of the processing box 1. The air supply holes are all located on the same straight line as the fan blades 23, and a dustproof net 24 is fixedly bonded to the air supply hole on the side wall of the processing box 1.

[0050] Specifically, when the output shaft of the stepper motor 32 drives the drive rod to rotate, the drive rod can drive the connecting rod integrally formed with it to rotate, causing the connecting rod to drive the fan blade 23 integrally formed with it to rotate. The airflow generated by the rotation of the fan blade 23 enters the processing box 1 through the air inlet to disturb the light fallen leaves and other debris, blowing the light fallen leaves and other debris to... Figure 2 The second collection box 5, located on one side of the air inlet, is used to classify the fallen debris.

[0051] After the fallen material enters the second collection box 5, it can be transported to the area below the arc plate 6 by the airflow. When the airflow re-enters the second collection box 5, the airflow can reduce the direct disturbance to the fallen material inside the second collection box 5 under the guidance of the arc plate 6, thereby reducing the possibility of the fallen material escaping from the second collection box 5 due to airflow disturbance.

[0052] like Figure 2 and Figure 6 As shown, the first collection box 4 is equipped with an auxiliary component for assisting the falling of fallen objects. The auxiliary component includes an auxiliary plate 25. The end of the drive frame 15 away from the air supply box 18 extends through the side wall of the drive box 3 and the side wall of the first collection box 4 and is integrally formed with the auxiliary plate 25 inside the first collection box 4. An inclined block 26 is welded to the bottom wall of the first collection box 4. An elastic block 27 is fixedly bonded to the bottom of the auxiliary plate 25. The inclined block 26 is located in the movement path of the elastic block 27.

[0053] Specifically, when the fallen debris enters the first collection box 4 through the through hole, it falls onto the inclined block 26. At this time, during the lateral reciprocating motion of the drive frame 15, it also drives the auxiliary plate 25, which is integrally formed with it, to reciprocate laterally. The auxiliary plate 25 drives the elastic block 27, which is fixedly bonded to it, to reciprocate laterally, so that the elastic block 27 pushes the fallen debris on the inclined block 26 during the lateral reciprocating motion to assist in the falling of the fallen debris.

[0054] While collecting the fallen debris, the controller also activates the heating plate to dry the fallen debris in the first collection box 4 and the second collection box 5. After drying, the pretreatment of the fallen debris is completed.

[0055] This invention drives an air supply component to operate, which in turn supplies air into the shaking cylinder 11. This air, through the shaking block 12, shaking rod 10, and pressure relief hole, causes the screening plate 7 to vibrate periodically. This high-frequency vibration of the screening plate 7 reduces clogging of the screen 8 while increasing its screening rate for fine particles such as humus. Simultaneously, the air supply component and the screening plate 7 work together to perform both mechanical and pneumatic screening of fallen materials, improving screening efficiency and quality.

[0056] Example 2: The main difference between this embodiment and Embodiment 1 lies in the structure of the driving component. Since the driving component is used to simultaneously drive the sorting component and the air supply component to improve the sorting and sieving effect of the fallen material, in addition to the driving component of Embodiment 1, the driving component can also be as follows: Figure 8 As shown. Specifically, the drive assembly includes a drive component fixedly connected to the inner wall of the drive housing 3 by screws. A controller is used to control the opening and closing of the drive component. A drive rod is fixedly connected to the output shaft of the drive component by coaxial screws. A cam 28 is eccentrically fixed and snapped onto the end of the drive rod away from the output shaft of the drive component. A drive plate 29 is provided inside the drive housing 3. The drive plate 29 has a drive groove for the output shaft of the drive component to pass through. A transmission block 30 is integrally formed symmetrically on one side of the drive plate 29. The transmission blocks 30 are all located in the movement path of the cam 28. Several limiting rods 17 are welded to the inner wall of the drive housing 3. The two ends of the drive plate 29 pass through the adjacent limiting rods 17 and slide laterally with the limiting rods 17. The rest of the structure is the same as in Embodiment 1. In this embodiment, a stepper motor 32 is selected as the drive component.

[0057] Specifically, in this embodiment, the operator controls the output shaft of the stepper motor 32 to rotate via a controller, causing the cam 28 to rotate eccentrically. During this rotation, the cam 28 can contact the transmission block 30, thereby pushing the transmission block 30 to move laterally. Figure 8 As shown, when the output shaft of the stepper motor 32 rotates clockwise, it drives the cam 28 to rotate eccentrically clockwise, pushing the right transmission block 30 to move to the right, which in turn drives the drive plate 29 integrally formed with it to move to the right. When the cam 28 continues to rotate until it contacts the left transmission block 30, the cam 28 pushes the left transmission block 30 to move to the left, which in turn drives the drive plate 29 integrally formed with it to move to the left, thereby realizing the lateral reciprocating motion of the drive plate 29. The drive plate 29 drives the air supply component to operate, and at the same time drives the sorting component to operate through the drive rod, so that the effect achieved by the drive component in this embodiment is the same as the effect of the drive component in embodiment 1.

[0058] It should be noted that, regardless of the type of drive component used in this application, as long as the drive component can simultaneously drive the sorting component and the air supply component, the overall structure of such a drive component is within the scope of protection of this application.

[0059] Example 3: The main difference between this embodiment and Embodiments 1 and 2 lies in the structure of the driving component. Since the driving component is used to simultaneously drive the sorting component and the air supply component to improve the sorting and sieving effect of the fallen material, in addition to the driving components of Embodiments 1 and 2, the driving component can also be as follows: Figure 9As shown. Specifically, the drive assembly includes a telescopic component fixedly connected to the inner wall of the processing box 1 with screws. A controller is used to control the opening and closing of the telescopic component. The output shaft of the telescopic component extends through the air supply assembly and is coaxially fixedly connected to a rack 16 with screws on one side of the air supply assembly. A rotating rod is rotatably fitted on the inner wall of the drive box 3. A full gear 31 is fixedly engaged on the rotating rod. The full gear 31 meshes with the rack 16. The sorting component is located at the end of the rotating rod away from the inner wall of the drive box 3. Several limiting rods 17 are welded to the inner wall of the drive box 3. The rack 16 passes through all the limiting rods 17 and slides laterally with the limiting rods 17.

[0060] In this embodiment, the telescopic component is an electric telescopic rod 33, and the structure of the air supply assembly is as follows: Figure 10 As shown, it includes an air supply box 18 welded to the inner wall of the drive box 3. The output shaft of the electric telescopic rod 33 extends through the air supply box 18 to one side of the air supply box 18. An air supply plate 19 is fixedly connected to the output shaft of the electric telescopic rod 33 inside the air supply box 18 by screws. The air supply plate 19 slides laterally with the inner wall of the air supply box 18. An air inlet check valve 20 and an air outlet pipe 21 are connected to the air supply box 18. An air outlet check valve 22 is connected at the connection between the air outlet pipe 21 and the air supply box 18. The end of the air outlet pipe 21 away from the air supply box 18 extends through the side wall of the drive box 3 and the side wall of the processing box 1 into the processing box 1 and connects with the lower part of the shaking cylinder 11. The rest of the structure is the same as in embodiment 1.

[0061] Specifically, in this embodiment, the operator controls the output shaft of the electric telescopic rod 33 to reciprocate, causing it to drive the rack 16, which is fixedly connected to it with screws, to reciprocate laterally. The rack 16 then drives the full gear 31, which meshes with it, to reciprocate, thus driving the sorting component to operate. Simultaneously, during the reciprocating motion, the output shaft of the electric telescopic rod 33 also drives the air delivery plate 19, which is fixedly connected to it with screws, to reciprocate laterally within the air delivery box 18. This causes the air outside the air delivery box 18 to be drawn into the air delivery box 18 through the inlet one-way valve 20, and then the air inside the air delivery box 18 to be delivered to the shaking cylinder 11 through the outlet one-way valve 22 and the outlet pipe 21. Therefore, the driving component and the air delivery component in this embodiment achieve the same effect as those in Embodiment 1.

[0062] It should be noted that, regardless of the type of drive component and air supply component used in this application, as long as the drive component can simultaneously drive the sorting component and the air supply component, and the air supply component can deliver gas into the shaking cylinder 11, the overall structure of such a drive component and air supply component is within the scope of protection of this application.

[0063] Scope of Protection: The core inventive point of this invention lies in simultaneously performing pneumatic screening and mechanical shaking operations on fallen materials to improve screening efficiency and quality. Its scope of protection specifically includes: 1. Drive mechanism: Any mechanism that synchronously drives the air supply component and the sorting component through drive components (stepper motor 32, servo motor, etc.) and telescopic components (electric telescopic rod 33, pneumatic telescopic rod, hydraulic rod, etc.) is considered an equivalent replacement.

[0064] 2. Vibration mechanism: Any structure that can supply air into the vibrating cylinder 11 (such as pumping air directly into the vibrating cylinder 11 through an air pump, or supplying gas into the vibrating cylinder 11 through a mechanical structure, etc.) is considered an equivalent replacement.

[0065] 3. Auxiliary mechanisms: Any structure that can assist in the collection and lowering of fallen debris (such as a structure that directly pushes the fallen debris to move, or a structure that indirectly drives the fallen debris to move) is considered an equivalent replacement.

[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
