Description

Technical Field

[0001] This invention relates to the field of plant protection equipment technology, and more specifically, to a plant protection machine for the efficient control of major pests of cowpea. Background Technology

[0002] During cowpea cultivation, diseased leaves, withered leaves, and insect-infested or damaged leaves (hereinafter referred to as "insect leaves") are the main breeding grounds and habitats for pests (such as cowpea pod borers, aphids, thrips, etc.). If these leaves remain on the plants or in field ditches and ridges for a long time, they can easily lead to the proliferation of pests and their spread to healthy plants, which will not only affect the growth and development of cowpeas, but also reduce yield and quality.

[0003] Currently, the removal of diseased, withered leaves and insect-infested flowers in cowpea fields relies heavily on manual labor. Workers must manually remove these plants one by one, sweeping away dead leaves from the ground. This process is not only labor-intensive and inefficient, but also fails to thoroughly clean hidden areas such as deep furrows and crevices in the ridges, creating loopholes in pest control and preventing the formation of a complete pest and disease control loop. Furthermore, existing plant protection equipment used for field cleaning suffers from limited functionality and poor adaptability. Some equipment only has a single function of blowing or sweeping, requiring multiple trips to complete the removal and collection of diseased, withered leaves and insect-infested flowers, making the process cumbersome. Therefore, there is an urgent need for a highly efficient plant protection machine for controlling major cowpea pests to solve these problems. Summary of the Invention

[0010] Preferably, the material suction and crushing assembly includes a support base fixedly connected to the inner wall of the bottom of the box, a protective shell fixedly connected to the inner circumference of the support base, a crusher shell fixedly connected to one end of the protective shell, a third motor fixedly connected inside the protective shell, an iron disc fixedly connected to the output end of the third motor, blades evenly distributed in a circular pattern fixedly connected to the outer circumference of the iron disc, and a suction pipe fixedly connected to the bottom of the crusher shell.

[0011] Preferably, the cross-section of the crusher shell is whistle-shaped, and one end of the housing is provided with a through groove to facilitate material discharge from the crusher shell, with one end of the crusher shell passing through the inside of the through groove.

[0012] Preferably, a suction cylinder is fixedly connected to the bottom outer wall of the box body. The suction cylinder is connected to the suction pipe.

[0015] The beneficial effects of this invention are: This invention provides a highly efficient plant protection machine for controlling major pests of cowpea. The machine achieves stable movement via a drive shaft driven by a rear wheel at the bottom of the casing, in conjunction with a rolling assembly. During this process, the roller within the rolling assembly provides the primary rolling support. The protrusions on the outer wall of the roller effectively reduce the contact area between the roller and the ground in the planting furrow, preventing the roller from compacting diseased leaves, withered leaves, and insect-infested flowers scattered in the furrow onto the ground, thus hindering subsequent cleaning. Furthermore, the protrusions on the outer circumference of the roller are distributed with a "sparser middle and denser ends" pattern, further adapting to the terrain characteristics of cowpea planting furrows. The middle area of ​​the furrow is relatively flat and has a denser distribution of diseased leaves, withered leaves, and insect-infested flowers; the sparser protrusions reduce the impact on the middle area. The design minimizes ground disturbance and prevents compaction of densely packed diseased, withered, and insect-infested leaves, ensuring effective cleaning of these areas by the subsequent sweeping components. Since the density of these leaves and insects is lower on the sides of the ditch, and they are close to the cowpea planting ridges, the terrain is prone to slight undulations due to ridge height differences. The densely distributed bumps better conform to these undulating terrains, enhancing the equipment's stability as it moves along the ditch edges and preventing it from shifting towards the ridges or the center of the ditch. This also strengthens the equipment's grip as it moves along the sides of the ditch, preventing it from shifting within the ditch itself. This improves overall stability during movement and protects against diseased, withered, and insect-infested leaves in different areas of the ditch, laying the foundation for efficient collection and processing of these leaves and insects by the subsequent material suction and crushing components.

[0016] This invention provides a highly efficient plant protection machine for controlling major pests of cowpeas. A blower can blow diseased leaves, withered leaves, and insect-infested flowers attached to cowpea plants to the furrows and ridges. Because the blower is fixedly connected to a vertical plate via a second spring, it vibrates during startup, causing it to swing. When the swinging blower touches the first springs on both sides, it generates a reaction force, returning to its original position. This cyclical change in the blower's angle allows the airflow to cover a wider area of ​​the cowpea plant, preventing the omission of some diseased and withered leaves due to a fixed blowing angle. This significantly improves the efficiency of blowing off diseased leaves, withered leaves, and insect-infested flowers. Furthermore, the dynamically changing blowing angle can gently "sweep" the surface of the cowpea plant while blowing off diseased leaves, withered leaves, and insect-infested flowers, reducing the attachment of pests (such as aphids and thrips) to the plant surface. This provides early assistance in pest control and double protection for subsequent cleaning of diseased leaves, withered leaves, and insect-infested flowers (reducing pest breeding grounds), thus achieving the goal of controlling major cowpea pests more efficiently.

[0017] This invention provides a highly efficient plant protection machine for controlling major pests of cowpea. Through a specially designed suction and crushing component, the suction cylinder is connected to the suction pipe of the suction and crushing component. When the third motor in the suction and crushing component drives the blades to rotate at high speed, a negative pressure is formed inside the crusher casing. This negative pressure is transmitted to the suction cylinder through the suction pipe, providing power for suction. The suction cylinder consists of an expansion section, a contraction section, and a suction section. The notch on the outer circumference of the suction section expands the suction range for diseased leaves, withered leaves, and insect-infested flowers, ensuring that scattered diseased leaves, withered leaves, and insect-infested flowers in the channels can smoothly enter the suction cylinder. Simultaneously, the contraction section is located between the expansion section and the suction section, and its inner diameter is smaller than that of the expansion section. The inner diameters of both the contraction section and the expansion section gradually decrease. This structural design allows the airflow to create an acceleration effect in the contraction section under negative pressure, enabling diseased leaves, withered leaves, and insect-infested flowers (which are larger in size and heavier than dust) to quickly enter the suction cylinder under the influence of the airflow. The feed pipe utilizes the volume and weight differences between diseased leaves, dead leaves, insects, flowers, and dust to slow down the speed at which dust moves with the airflow. Larger diseased leaves, dead leaves, and insects can continue to move forward in the accelerated airflow, while finer dust, due to its lower inertia and greater susceptibility to airflow disturbances, tends to settle or remain outside the suction cylinder in the area where the inner diameter changes between the expansion and contraction sections. This reduces the amount of dust sucked into the suction pipe and the crusher housing, ensuring efficient collection of diseased leaves, dead leaves, and insects while preventing a large amount of dust from accumulating inside the crusher housing and affecting the operating efficiency of the suction and crushing components. This provides a guarantee for subsequent crushing of diseased leaves, dead leaves, and insects, as well as for the stable operation of the equipment. The whistle-shaped crusher housing accelerates material flow. After the blades crush the material, the crushed material can be discharged through the channel at the end of the housing, preventing the residue of diseased leaves, dead leaves, and insects from becoming a breeding ground for pests and reducing material accumulation, which facilitates subsequent processing.

[0018] This invention provides a highly efficient plant protection machine for controlling major pests of cowpeas. One end of a blower in the blowing assembly is fixedly connected to an air outlet. An air guide pipe inserted into the outer circumference of the air outlet delivers a portion of the airflow to the transmission pipe of the rolling assembly. The transmission pipe is connected to the inside of the roller. The airflow is ultimately ejected through jet holes on a protrusion on the outer circumference of the roller. The protrusion located in the middle of the roller provides a blowing force towards the suction cylinder to diseased, withered leaves and insect-infested flowers falling into the furrows, effectively improving the suction cylinder's suction function. The air jet holes located on the protrusions at both ends of the roller body are inclined, which can concentrate the diseased leaves, withered leaves and insect flowers on both sides of the groove and blow them towards the center, improving the cleaning effect of diseased leaves, withered leaves and insect flowers in the groove. At the same time, during the rolling process of the roller body, the arc plate set on one side can not only scrape and clean the diseased leaves, withered leaves and insect flowers adhering to the roller body surface, but also block and seal the air jet holes on the protrusions on the side of the roller body away from the suction cylinder, ensuring the blowing force of the protrusions on the side of the roller body closer to the suction cylinder.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0030] Please see Figures 1-8 A highly efficient plant protection machine for controlling major pests of cowpea includes a housing 1, the top of which is equipped with a blower assembly for blowing off diseased, withered, and insect-infested cowpea leaves and flowers. One end of the box 1 is equipped with a cleaning component for cleaning diseased leaves, dead leaves and insect flowers on the furrows and ridges; The interior of the box 1 is equipped with a material suction and crushing component for collecting diseased leaves, dead leaves, and insect flowers after they have been swept by the cleaning component; A push rod 2 is fixedly connected to one side of the outer wall of the housing 1. A control panel 3 is fixedly connected to the outer circumference of the push rod 2. A battery pack 30 is installed inside the housing 1. A baffle 31 for limiting and fixing the battery pack 30 is fixedly connected inside the housing 1. The bottom of the housing 1 is provided with rear wheels 18 and drive shaft 19 for easy movement. The drive shaft 19 is fixedly connected to the two rear wheels 18. A triangular plate is fixedly connected to the bottom outer wall of the housing 1. Both ends of the drive shaft 19 are rotatably connected to the triangular plate. The bottom of the housing 1 is equipped with a rolling component 27 to ensure stable movement of the device.

[0031] Furthermore, the blowing assembly includes vertical plates 14 fixedly connected to the outer walls of both sides of the box 1. A second spring 17 is fixedly connected to one side of the outer wall of the vertical plate 14. A blower 11 is fixedly connected to the end of the second spring 17 away from the vertical plate 14. The blower 11 can blow the diseased leaves and withered leaves attached to the cowpea plants to the furrow and ridge area.

[0032] Furthermore, a support plate 16 is fixedly connected to one outer wall of the vertical plate 14, and a first spring 15 is fixedly connected to the top outer wall of the support plate 16. The first springs 15 are distributed on the left and right sides below the hair dryer 11. Since the hair dryer 11 is fixedly connected to the vertical plate 14 through the second spring 17, a certain vibration amplitude will be generated during the start-up process of the hair dryer 11, causing it to swing. When the swinging hair dryer 11 touches the first springs 15 on both sides, a reaction force will be generated to reset it, thereby repeatedly realizing the cycle of the blowing angle of the hair dryer 11. The changing airflow allows it to cover a wider area of ​​the cowpea plant, preventing the omission of diseased, withered, and insect-infested leaves due to a fixed wind angle. This significantly improves the efficiency of blowing off diseased, withered, and insect-infested leaves and flowers. In addition, the dynamically changing wind angle can gently "sweep" the surface of the cowpea plant while blowing off diseased, withered, and insect-infested leaves and flowers, reducing the attachment of pests (such as aphids and thrips) to the plant surface. This provides early assistance in pest control and creates a double guarantee for subsequent cleaning of diseased, withered, and insect-infested leaves and flowers (reducing the breeding grounds for pests), thus achieving the goal of controlling the main pests of cowpeas more efficiently.

[0033] Furthermore, the cleaning assembly includes a first motor 6 and a second motor 7 located at the end of the housing 1. The output end of the first motor 6 is fixedly connected to a flat brush disc 4 for cleaning the ridge surface, and the output end of the second motor 7 is fixedly connected to a side brush disc 5 for cleaning the furrows. The side brush disc 5 is inclined. The first motor 6 drives the flat brush disc 4 to clean the ridge surface, and the second motor 7 drives the inclined side brush disc 5 to penetrate into the furrows for cleaning.

[0034] Furthermore, a first fixing screw 20 and a second fixing screw 23 are fixedly connected to the bottom inner wall of the housing 1, respectively. A first connecting rod 8 is fixedly connected to the top outer wall of the first motor 6. A first adjusting rod 9 is fixedly connected to one side of the first connecting rod 8. A through-type second adjusting groove 22 is opened on the top of the first adjusting rod 9. The second fixing screw 23 passes through the inside of the first adjusting rod 9. A fixing nut 24 for fixing the first adjusting rod 9 is threadedly connected to the outer circumference of the second fixing screw 23. The two fixing nuts 24 are located on the upper and lower sides of the first adjusting rod 9, respectively. A second connecting rod 10 is fixedly connected to the outer wall of one end of the second motor 7. The other end of the connecting rod 10 is fixedly connected to a second adjusting rod 25. The top outer wall of the second adjusting rod 25 has a through first adjusting groove 21. The first fixing screw 20 passes through the inside of the first adjusting groove 21. The second adjusting rod 25 is fixedly connected to the first fixing screw 20 by two fixing nuts 24. If it is necessary to adapt to different widths of ridges and ditches, the fixing nuts 24 can be loosened. The first adjusting rod 9 can move along the second fixing screw 23 through the second adjusting groove 22, and the second adjusting rod 25 can move along the first fixing screw 20 through the first adjusting groove 21. After adjusting the position of the flat brush plate 4 and the side brush plate 5, the fixing nuts 24 are tightened again to ensure that there are no dead corners in the cleaning.

[0035] Furthermore, the material suction and crushing assembly includes a support base 35 fixedly connected to the inner wall of the bottom of the housing 1. A protective shell 33 is fixedly connected to the inner circumference of the support base 35. A crusher housing 32 is fixedly connected to one end of the protective shell 33. A third motor 34 is fixedly connected inside the protective shell 33. An iron disc 36 is fixedly connected to the output end of the third motor 34. Blades 37, evenly spaced and circularly distributed, are fixedly connected to the outer circumference of the iron disc 36. A suction pipe is fixedly connected to the bottom of the crusher housing 32. When the third motor 34 in the material suction and crushing assembly drives the blades 37 to rotate at high speed, a negative pressure is formed inside the crusher housing 32. The negative pressure is transmitted to the suction pipe. The material cylinder 26 provides power for material suction. It is fixedly connected to the bottom outer wall of the housing 1 and is connected to the suction pipe. The material cylinder 26 includes a contraction section 2601, an expansion section 2602, and a suction section 2603. The outer circumferential wall of the suction section 2603 has a notch 2604. The contraction section 2601 is located in the middle of the expansion section 2602 and the suction section 2603. The inner diameter of the contraction section 2601 is smaller than the inner diameter of the expansion section 2602. The inner diameters of both the contraction section 2601 and the expansion section 2602 gradually decrease. The material cylinder 26 is composed of the expansion section 2602, the contraction section 2601, and the suction section 2603. The notch 2604 on the outer circumference of the feed section 2603 expands the suction range of diseased leaves, withered leaves, and insect-infested flowers, ensuring that the diseased leaves, withered leaves, and insect-infested flowers scattered in the channel can smoothly enter the suction cylinder 26. Meanwhile, the contraction section 2601 is located between the expansion section 2602 and the suction section 2603, and its inner diameter is smaller than that of the expansion section 2602. The inner diameters of both the contraction section 2601 and the expansion section 2602 gradually decrease. This structural design allows the airflow to create an acceleration effect in the contraction section 2601 under negative pressure, enabling the diseased leaves, withered leaves, and insect-infested flowers (which are larger in volume and heavier than dust) to quickly enter the suction pipe under the influence of the airflow. Simultaneously, the diseased leaves, withered leaves, and insect-infested flowers... The difference in volume and weight of dust slows down the speed at which dust moves with the airflow. Larger diseased leaves, withered leaves, and insect-infested flowers can continue to move forward in the accelerated airflow, while finer dust, due to its lower inertia, is more affected by airflow disturbances and tends to settle or remain outside the suction cylinder 26 in the area where the inner diameter of the expansion section 2602 and the contraction section 2601 changes. This reduces the amount of dust sucked into the suction pipe and the crusher housing 32, ensuring efficient collection of diseased leaves, withered leaves, and insect-infested flowers while preventing a large amount of dust from accumulating inside the crusher housing 32 and affecting the operating efficiency of the suction and crushing components. This provides a guarantee for the subsequent crushing and processing of diseased leaves, withered leaves, and insect-infested flowers and for the stable operation of the equipment.

[0036] Furthermore, the cross-section of the crusher housing 32 is whistle-shaped, and a through groove 29 is provided at one end of the box body 1 to facilitate the discharge of material from the crusher housing 32. One end of the crusher housing 32 passes through the inside of the through groove 29. The whistle-shaped crusher housing 32 can accelerate the flow of material. After the blades 37 crush the material, the crushed material can be discharged through the through groove 29 at the end of the box body 1. This not only avoids diseased leaves, withered leaves and insect flowers remaining as a breeding ground for pests, but also reduces material accumulation and facilitates subsequent processing.

[0037] Furthermore, the rolling assembly 27 includes a roller body 2701, a transmission pipe 2702, and protrusions 2704. Fixing plates 28 are fixedly connected to both outer walls of the housing 1. The fixing plates 28 are rotatably connected to the transmission pipe 2702, which is connected to the interior of the roller body 2701. The protrusions 2704 are distributed on the outer circumference of the roller body 2701 in a sparser middle and denser end configuration. The roller body 2701 in the rolling assembly 27 provides the main rolling support, while the protrusions 2704 on the outer wall of the roller body 2701 effectively reduce the contact area between the roller body 2701 and the ground of the ditch during rolling, preventing the roller body 2701 from pressing the diseased and withered leaves scattered in the ditch onto the ground, thus affecting subsequent treatment. The cleaning effect of diseased leaves, withered leaves, and insect-infested flowers is excellent. The protrusions 2704 on the outer circumference of the roller body 2701 are distributed with a "sparse in the middle and dense at both ends" pattern, which can further adapt to the terrain characteristics of the cowpea planting furrows. The middle area of ​​the furrow is relatively flat and the distribution of diseased leaves, withered leaves, and insect-infested flowers is relatively dense. The sparse protrusions 2704 can reduce the interference with the ground in the middle area and avoid the situation where the dense diseased leaves, withered leaves, and insect-infested flowers are compacted and cannot be cleaned. This ensures the cleaning effect of the subsequent cleaning components on the diseased leaves, withered leaves, and insect-infested flowers on both sides of the furrow. The density of diseased leaves, withered leaves, and insect-infested flowers on both sides of the furrow is lower and closer to the cowpea planting ridge. The terrain is prone to slight undulations due to the height difference of the ridge. The densely distributed protrusions 2704 can better fit the undulating terrain on both sides and enhance the support and stability of the equipment when moving at the edge of the furrow. Qualitative measures are taken to prevent the equipment from shifting towards the center of the ridge or furrow, while also enhancing the equipment's grip when moving along the sides of the furrow, preventing it from shifting within the furrow, and improving the overall stability during movement and the protection of diseased, withered, and insect-infested leaves in different areas of the furrow. This lays the foundation for the efficient collection and processing of diseased, withered, and insect-infested leaves by the subsequent material suction and crushing components. Air jet holes are provided on the outer circumference of the protrusion 2704, and these holes are connected to the interior of the roller body 2701. The air jet holes on the outer wall of the protrusion 2704 at both ends of the roller body 2701 are inclined. One end of a blower 11 is fixedly connected to an air outlet 12, and an air guide pipe 13 is inserted into the outer circumference of the air outlet 12. The other end of the air guide pipe 13 is connected to a transmission pipe 2702. Because one of the blowers 11... One end is fixedly connected to an air outlet 12. The air guide pipe 13 inserted into the outer circumference of the air outlet 12 will transport part of the airflow to the transmission pipe 2702 of the rolling assembly 27. The transmission pipe 2702 is connected to the inside of the roller body 2701. The airflow is finally ejected through the air jet hole on the protrusion 2704 on the outer circumference of the roller body 2701. The protrusion 2704 located in the middle of the roller body 2701 can give the diseased leaves, dead leaves and insect flowers falling in the ditch a blowing force close to the suction cylinder 26, which plays a good auxiliary role in the suction work of the suction cylinder 26. The air jet holes of the protrusion 2704 located at both ends of the roller body 2701 are opened at an angle, which can concentrate the diseased leaves, dead leaves and insect flowers on both sides of the ditch to the middle, improving the cleaning effect of diseased leaves, dead leaves and insect flowers in the ditch.

[0038] Furthermore, an arc-shaped plate 2703 is fixedly connected to the bottom outer wall of the box 1. The inner circumference of the arc-shaped plate 2703 contacts the outer circumference of the protrusion 2704. The cross-section of the arc-shaped plate 2703 is semi-circular, and a sloping groove is provided at one end of the arc-shaped plate 2703. During the rolling process of the roller 2701, the arc-shaped plate 2703 on one side can not only scrape and clean the diseased leaves, withered leaves and insect flowers adhering to the surface of the roller 2701, but also block and seal the air jet hole of the protrusion 2704 on the side of the roller 2701 away from the suction cylinder 26, thus ensuring the blowing force of the protrusion 2704 on the side of the roller 2701 close to the suction cylinder 26.

[0039] In summary, with the help of the above-mentioned technical solution of the present invention, during use, the operator holds the push rod 2 to push the equipment to move in the trench. When the equipment moves, the rear wheel 18 at the bottom of the box 1, driven by the transmission shaft 19, cooperates with the rolling assembly 27 to achieve stable movement. In this process, the roller 2701 in the rolling assembly 27 plays the main rolling support role. The protrusions 2704 provided on the outer wall of the roller 2701 can effectively ensure that the roller 2701 reduces the contact area with the trench ground during rolling, and avoids the roller 2701 pressing the diseased leaves, withered leaves and insect flowers scattered in the trench onto the ground, thereby affecting the subsequent cleaning effect of diseased leaves, withered leaves and insect flowers. The protrusions 2704 on the outer circumference of the roller 2701 are distributed in a "sparse in the middle and dense at both ends" manner, which can further adapt to the terrain characteristics of the cowpea planting trench. The middle area of ​​the trench is relatively... For flat areas with a high density of diseased, withered, and insect-infested leaves, the sparsely distributed bumps 2704 reduce interference with the ground in the central area, preventing compaction of the dense diseased, withered, and insect-infested leaves and ensuring the cleaning effect of the subsequent sweeping components on the diseased, withered, and insect-infested leaves on both sides of the ditch. However, the density of diseased, withered, and insect-infested leaves and the area close to the cowpea planting ridges are lower, and the terrain is prone to slight undulations due to the height difference of the ridges. The densely distributed bumps 2704 can better conform to the undulating terrain on both sides, enhancing the support stability of the equipment when moving along the edge of the ditch, preventing the equipment from shifting towards the ridge or the center of the ditch. At the same time, it enhances the grip of the equipment when moving along both sides of the ditch, preventing the equipment from shifting within the ditch, improving the overall stability during movement and the protection effect on diseased, withered, and insect-infested leaves and the area of ​​the ditch in different regions. This lays the foundation for the efficient collection and processing of diseased, withered, and insect-infested leaves and the area of ​​the ditch by the subsequent material suction and crushing components. During the equipment movement, the staff first activates the blower 11. The blower 11 blows diseased and withered leaves from the cowpea plants down into the furrows and ridges. Since the blower 11 is fixedly connected to the vertical plate 14 via the second spring 17, it vibrates during startup, causing it to swing. When the swinging blower 11 touches the first springs 15 on either side, a reaction force is generated, causing it to return to its original position. This cycle repeats, achieving a cyclical change in the blowing angle of the blower 11. The airflow can cover a wider area of ​​the cowpea plant, avoiding the omission of some diseased leaves, withered leaves, and insect flowers due to a fixed wind angle, greatly improving the efficiency of blowing off diseased leaves, withered leaves, and insect flowers. In addition, the dynamically changing wind angle can gently "sweep" the surface of the cowpea plant while blowing off diseased leaves, withered leaves, and insect flowers, reducing the attachment of pests (such as aphids and thrips) to the plant surface, assisting in the early control of pests, and providing a double guarantee for the subsequent cleaning of diseased leaves, withered leaves, and insect flowers (reducing the breeding grounds of pests), thus achieving the goal of controlling the main pests of cowpea more efficiently. After the diseased, withered leaves and insect-infested flowers on the cowpea plants are blown off by the blower assembly, the cleaning assembly starts to work. The first motor 6 drives the flat brush 4 to clean the ridge surface, and the second motor 7 drives the inclined side brush 5 to clean the furrows. If it is necessary to adapt to different widths of ridges and furrows, the fixing nut 24 can be loosened. The second adjusting groove 22 of the first adjusting rod 9 moves along the second fixing screw 23, and the first adjusting groove 21 of the second adjusting rod 25 moves along the first fixing screw 20. After adjusting the position of the flat brush 4 and the side brush 5, the fixing nut 24 is tightened again to ensure that there are no dead corners in the cleaning. Afterwards, the material suction and crushing assembly is activated. The material suction cylinder 26 is connected to the material suction pipe of the material suction and crushing assembly. When the third motor 34 in the material suction and crushing assembly drives the blades 37 to rotate at high speed, a negative pressure is formed inside the crusher housing 32. The negative pressure is transmitted to the material suction cylinder 26 through the material suction pipe, providing power for material suction. The material suction cylinder 26 is composed of an expansion section 2602, a contraction section 2601, and a material suction section 2603. The notch 2604 on the outer circumference of the material suction section 2603 can enlarge diseased leaves, withered leaves, and insect-infested flowers. The suction range ensures that diseased leaves, withered leaves, and insect-infested flowers scattered in the channel can smoothly enter the suction cylinder 26. Simultaneously, the contraction section 2601 is located between the expansion section 2602 and the suction section 2603, and its inner diameter is smaller than that of the expansion section 2602. The inner diameters of both the contraction section 2601 and the expansion section 2602 gradually decrease. This structural design allows the airflow to create an acceleration effect in the contraction section 2601 under negative pressure, allowing the diseased leaves, withered leaves, and insect-infested flowers (which are larger in volume and heavier than dust) to be carried by the airflow. The material quickly enters the suction pipe under the airflow. At the same time, the difference in volume and weight between diseased leaves, dead leaves, insect flowers and dust is used to slow down the speed of dust movement with the airflow. Larger diseased leaves, dead leaves and insect flowers can continue to move forward in the accelerated airflow, while fine dust, due to its smaller inertia and greater influence from airflow disturbance, is more likely to settle or remain outside the suction cylinder 26 in the area where the inner diameter changes between the expansion section 2602 and the contraction section 2601. This reduces the amount of dust sucked into the suction pipe and the crusher housing 32, ensuring efficient collection of diseased leaves, dead leaves and insect flowers, and preventing a large amount of dust from accumulating in the crusher housing 32 and affecting the operating efficiency of the suction and crushing components. This provides a guarantee for the subsequent crushing and processing of diseased leaves, dead leaves and insect flowers and the stable operation of the equipment. The whistle-shaped crusher housing 32 can accelerate the flow of materials. After the blades 37 crush the materials, the crushed materials can be discharged through the through groove 29 at the end of the housing 1. This prevents the diseased leaves, dead leaves and insect flowers from becoming a breeding ground for pests and reduces material accumulation, making it easier for subsequent processing. In addition, one end of one of the blowers 11 is fixedly connected to an air outlet 12. The air guide pipe 13 inserted into the outer circumference of the air outlet 12 will transport part of the airflow to the transmission pipe 2702 of the rolling assembly 27. The transmission pipe 2702 is connected to the inside of the roller body 2701. The airflow is finally ejected through the jet hole on the protrusion 2704 on the outer circumference of the roller body 2701. The protrusion 2704 located in the middle of the roller body 2701 can provide a blowing force to the diseased leaves, withered leaves and insect flowers falling in the groove in the direction close to the suction cylinder 26, which plays a good auxiliary role in the suction work of the suction cylinder 26. The protrusion 2704 located in the middle of the roller body 2701 can provide a blowing force to the diseased leaves, withered leaves and insect flowers falling in the groove in the direction close to the suction cylinder 26, which plays a good auxiliary role in the suction work of the suction cylinder 26. The air jet holes of the two end protrusions 2704 are opened at an angle, which can concentrate the diseased leaves, withered leaves and insect flowers on both sides of the channel and blow them towards the center, improving the cleaning effect of diseased leaves, withered leaves and insect flowers in the channel. At the same time, during the rolling of the roller body 2701, the arc plate 2703 set on one side can not only scrape and clean the diseased leaves, withered leaves and insect flowers adhering to the surface of the roller body 2701, but also block and seal the air jet holes of the protrusions 2704 on the side of the roller body 2701 away from the suction cylinder 26, ensuring the blowing force of the protrusions 2704 on the side of the roller body 2701 close to the suction cylinder 26.
