Description

Technical Field

[0001] This invention relates to the field of building drainage technology, specifically a building drainage device. Background Technology

[0002] Southern regions are prone to typhoons and strong winds, and receive a lot of rainfall. Therefore, roofs in the south are often designed with slopes. This makes it easier for rainwater to flow down the slope, thus avoiding the problem of water accumulation on the roof. In addition, the sloped roofs in the south also need drainage pipes. Drainage pipes can effectively guide the rainwater flowing down the sloped roof, making it convenient to collect and discharge the rainwater. Furthermore, due to the frequent strong winds in the south, leaves are more easily blown onto the sloping roof. When rainwater flows down the sloping roof, it washes away the leaves, causing them to be washed into the drainpipes. This clogs the drainpipe openings and affects the normal drainage effect. Especially during heavy rainfall, clogged drainpipes can easily lead to flooding. Therefore, workers need to climb onto the roof during brief breaks in the rain to clear the debris blocking the drainpipe openings. Because the sloping roof is tilted, its support is weak, and the surface becomes smoother after being washed by rainwater, which not only increases the difficulty of cleaning for workers but also poses a risk of slipping and falling. In view of this, in order to overcome the above-mentioned technical problems, the present invention proposes a building drainage device, which solves the above-mentioned technical problems. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention proposes a building drainage device. Through the cooperation between the mounting plate and the rotating column, the rotating column drives the filter screen to move via the mounting plate. The filter screen, through a push plate, pushes leaves that are blocking the filter screen to the unloading module for collection. At this point, the filter screen, continuously extending out of the machine body, again blocks and filters the water outlet. This not only prevents rainwater from entering the machine body and clogging the drain pipe, but also ensures that leaves do not block rainwater from entering the drain pipe, increasing the drainage capacity. It eliminates the need for workers to climb onto the roof to clear leaves, avoiding the danger of slipping and falling, improving worker safety, and reducing the difficulty of cleaning.

[0004] The technical solution adopted by this invention to solve its technical problem is: a building drainage device according to this invention, comprising: The machine body has a water inlet on one side and a water outlet at the lower end.

A rotating column is located inside the machine body and rotatably connected to it. A drive motor is fixedly installed at the upper end of the machine body and its output end is fixedly connected to the rotating column. The filter screen is wound around the surface of the rotating column, and a pushing module is installed on the surface of the filter screen. The pushing module is used to push leaves away from the filter screen. The unloading module is installed on one side of the machine body; the unloading module is used to unload leaves from one side of the filter screen.

[0015] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0016] like Figures 1 to 8 As shown, the building drainage device of the present invention includes: The machine body 1 has a water inlet 11 on one side and a water outlet 12 at the lower end. A drain pipe 13 is fixedly connected to the lower end of the water outlet 12. A filter screen 14 is slidably connected inside the water inlet 11 and is slidably connected to the upper end of the machine body 1. A rotating column 15 is provided inside the machine body 1 and is rotatably connected to the machine body 1. A drive motor 16 is fixedly installed at the upper end of the machine body 1 and its output end is fixedly connected to the rotating column 15. The filter screen 14 is wound around the surface of the rotating column 15. A pushing module is installed on the surface of the filter screen 14 to push leaves away from the filter screen 14. The unloading module is installed on one side of the body 1; the unloading module is used to unload the leaves on one side of the filter screen 14.

[0017] In one embodiment of the present invention, the pushing module includes a push plate 21; a mounting plate 2 is fixedly connected to the surface of the filter screen 14; the mounting plate 2 is fixedly connected to the filter screen 14; a toothed groove 151 is formed on the surface of the rotating column 15; the mounting plate 2 engages with the toothed groove 151; a mounting groove 22 is formed on the side of the mounting plate 2 away from the rotating column 15; the push plate 21 is slidably connected in the mounting groove 22 by a connecting spring 221. Due to the frequent strong winds in the south, leaves are more easily blown onto the sloping roof. When rainwater flows down the sloping roof, it washes away the leaves, causing them to be washed into the drain pipe 13. This clogs the drain pipe 13, affecting its normal drainage. Especially during heavy rainfall, the blockage of the drain pipe 13 can easily lead to flooding. Therefore, workers need to climb onto the roof during brief breaks in the rain to clear the debris blocking the drain pipe 13. Because the sloping roof is tilted, its support is weak, and the surface becomes smoother due to the rain, which not only increases the difficulty of cleaning but also poses a risk of workers slipping and falling. During operation, the user fixes the unit 1 to the eaves and connects the drain pipe 13 to the outlet 12 of the unit 1. When rainwater flows down from the sloping roof, it washes leaves from the roof to the unit 1. The rainwater then enters the unit 1 through the filter 14 passing through the inlet 11. The rainwater flowing into the unit 1 then flows through the outlet 12 into the drain pipe 13, allowing the drain pipe 13 to discharge the rainwater. Because the unit 1 is in a semi-enclosed state, it can block the upper part of the inlet 11, preventing leaves from falling into the unit 1 and ensuring that the inlet 11 is not blocked by leaves. However, as leaves continue to be washed to the filter 14, the rainwater... As the mesh of filter 14 is continuously blocked, the operator controls the drive motor 16 to rotate the rotating column 15. This causes the toothed grooves 151 on the surface of the rotating column 15 to rotate. Since the mounting plate 2 on the surface of filter 14 engages with the toothed grooves 151 on the surface of the rotating column 15, the rotating column 15 can push the mounting plate 2 through the groove walls of the toothed grooves 151, causing the filter 14 to rotate around the rotating column 15. During the movement of the filter 14 within the machine body 1, the mounting plate 2 slides against the inner wall of the machine body 1. At this time, the mounting groove 22 is located on the side of the mounting plate 2 closest to the machine body 1. Therefore, during this sliding contact between the mounting plate 2 and the inner wall of the machine body 1... During the dynamic contact process, the push plate 21 in the mounting groove 22 is blocked by the inner wall of the body 1 and squeezes the connecting spring 221 near the bottom of the groove. The mounting plate 2 can push the push plate 21 inside the mounting groove 22 to move synchronously. At this time, the side of the push plate 21 away from the body 1 slides in contact with the body 1. When the mounting plate 2 on the surface of the filter screen 14 enters the water inlet 11, the mounting plate 2 no longer slides in contact with the body 1, so that the push plate 21 in the mounting groove 22 is no longer blocked by the body 1. Under the push of the restoring force of the connecting spring 221, the push plate 21 that has extended out of the mounting groove 22 can extend out of the water inlet 11. As the push plate 21 extends out of the inlet 11, the leaves blocked by the filter screen 14 will be between two adjacent push plates 21. As the filter screen 14 drives the push plate 21 to move continuously, the push plate 21 can push the leaves blocked by the filter screen 14 to move synchronously until the push plate 21 pushes the leaves blocked by the filter screen 14 to the unloading module. At this time, the outlet 12 is no longer blocked by the leaves, increasing the amount of water entering through the outlet 12. The unloading module can collect the leaves pushed by the push plate 21, preventing the leaves from accumulating on the sloping roof and preventing strong winds from blowing the accumulated leaves away on the sloping roof again, thus reducing the blockage of the filter screen 14 at the outlet 12 caused by the leaves.When the push plate 21 passes the unloading module, it contacts the body 1, causing the push plate 21 to squeeze the connecting spring 221 into the mounting groove 22 under the blocking force of the body 1. The leaves that are attached to the filter screen 14 due to the tension of the rainwater will be scraped off the filter screen 14 by the inner wall of the body 1, so that the body 1 cleans the surface of the filter screen 14. The cleaned filter screen 14 rotates around the rotating rod under the drive of the mounting plate 2 until the filter screen 14 that has entered the body 1 moves to the outlet 12 again. At this time, the filter screen 14 that has leaked out of the body 1 is not blocked by the leaves, thus improving the filtration effect of the filter screen 14. This invention utilizes the cooperation between the mounting plate 2 and the rotating column 15 to drive the filter screen 14 to move via the mounting plate 2. The filter screen 14 can be pushed by the push plate 21 to the unloading module for collection. At this time, the filter screen 14, which extends out of the machine body 1, once again blocks and filters the water outlet 12. This not only prevents rainwater from entering the machine body 1 and clogging the drain pipe 13, but also ensures that the leaves will not block rainwater from entering the drain pipe 13, thereby increasing the drainage capacity of the drain pipe 13. This eliminates the need for workers to climb onto the roof to clean up the leaves, thus avoiding the danger of slipping and falling, improving the safety of workers, and reducing the difficulty of cleaning.

[0018] In one embodiment of the present invention, the unloading module includes an unloading column 3; the rotating column 15 is rotatably connected inside the machine body 1; the unloading column 3 and the rotating column 15 are connected by a gear set 23; a discharge port 17 is provided on one side of the machine body 1; the discharge port 17 is located between the unloading column 3 and the rotating column 15.

[0019] In one embodiment of the present invention, an extrusion groove 31 is provided on the surface of the unloading column 3; an extrusion plate 32 is slidably connected in the extrusion groove 31; the extrusion plate 32 and the bottom of the extrusion groove 31 are fixedly connected by a return spring 33.

[0020] In one embodiment of the present invention, a circular groove 321 is provided on the side of the extrusion plate 32 near the rotating column 15; the circular groove 321 is inclined; a claw pin 322 is slidably connected in the circular groove 321; the claw pin 322 is fixedly connected to the bottom of the circular groove 321 by a fixing spring 323; an electromagnet 34 is embedded in the bottom of the circular groove 321; and a pressure sensor 35 is embedded in the bottom of the extrusion groove 31. During operation, the claw pin 322 is made of PTFE material and is arc-shaped. The rotating column 15 drives the mounting plate 2 to move the filter belt and push plate 21 towards the discharge column 3. This causes the push plate 21 to push the leaves blocked by the filter belt to the discharge column 3. Since the discharge column 3 and the rotating column 15 are connected by a gear set 23, they rotate towards each other. When the leaves move between the discharge column 3 and the rotating column 15 under the push of the push plate 21, the discharge column 3 can push the leaves located between the discharge column 3 and the rotating column 15 through the extrusion plate 32. This allows the leaves to pass through the gap between the discharge column 3 and the rotating column 15 and move towards the discharge port 17, so that the leaves can fall into the discharge port 17. Inside the woven bag; by setting a squeezing plate 32, the squeezing plate 32 can extend out of the squeezing groove 31 under the push of the return spring 33, thereby increasing the length of the squeezing plate 32 extending out of the squeezing groove 31, thus increasing the range of the squeezing plate 32 pushing the leaves around the discharge column 3, until the squeezing plate 32 pushes the leaves to the rotating column 15. At this time, the squeezing plate 32 contacts the rotating column 15 through the filter screen 14 attached to the surface of the rotating column 15, so that the rotating column 15 can squeeze the squeezing plate 32 to continuously compress the return spring 33 into the squeezing groove 31, so that the squeezing plate 32 in contact with the rotating column 15 can generate an effective pushing force on the leaves between the rotating column 15 and the discharge column 3, ensuring that the leaves are effectively pushed into the discharge port 17, improving the discharge effect of the discharge column 3, and squeezing The cooperation between plate 32 and return spring 33 not only increases the pushing range of extrusion plate 32, but also prevents extrusion plate 32 from being damaged by extrusion from rotating column 15. The claw nail 322, when the extrusion plate 32 extends out of extrusion groove 31 and pushes the leaves around discharge column 3, extends out of circular groove 321 under the restoring force of fixed spring 323. During the pushing process of extrusion plate 32, leaves continuously accumulate on one side of extrusion plate 32, causing leaves near the end of extrusion plate 32 away from discharge column 3 to be squeezed out of extrusion plate 32 by the accumulated leaves. The claw nail 322 effectively blocks the leaves pushed by extrusion plate 32, thereby increasing the pushing amount of leaves by extrusion plate 32. When plate 32 drives claw nail 322 to rotate to a position close to rotating column 15, pressing plate 32 is blocked by rotating column 15 and enters pressing groove 31. By simply embedding pressure sensor 35 at the bottom of pressing groove 31, it is possible to monitor whether pressing plate 32 rotates to contact filter screen 14. That is, when pressing plate 32 contacts filter screen 14 attached to the surface of rotating column 15, pressing plate 32 squeezes return spring 33 into pressing groove 31. At this time, return spring 33 will exert pressure on pressure sensor 35. When it is detected that pressing plate 32 is in contact with filter screen 14, electromagnet 34 is energized, so that electromagnet 34 attracts claw nail 322 into circular groove 321, thereby allowing leaves pierced by claw nail 322 to be blocked by pressing plate 32 and detached from claw nail 322.This allows leaves pierced by the claw nail 322 to enter the discharge port 17 under the push of the extrusion plate 32. The side of the extrusion plate 32 with the circular groove 321 is set as an inclined surface. When the extrusion plate 32 rotates to the end of the discharge port 17, the inclined surface of the extrusion plate 32 contacts the end of the discharge port 17, causing the discharge port 17 to exert a pressing force on the inclined surface of the extrusion plate 32. This pressing force perpendicular to the inclined surface generates a component force perpendicular to the extrusion groove 31 on the extrusion plate 32. Under the push of this component force, the extrusion plate 32 drives the claw nail 322 and completely enters the extrusion groove 31. At this point, when the pressure sensor 35 senses that the pressure has reached the upper limit of the set value, the pressure sensor 35 transmits an electrical signal to the electromagnet 34, causing the electromagnet 34 to be de-energized. This continues until the extrusion plate 32 rotates and moves beyond the machine body 1. The claw nail 322 and the pressing plate 32 continuously extend from the circular groove 321 and the pressing groove 31 under the push of the fixing spring 323 and the return spring 33, so that the claw nail 322 and the pressing plate 32 push the leaves. By using a woven bag made of polypropylene, on the one hand, the woven bag can collect the leaves, preventing them from being blown onto other rooftops by strong winds; on the other hand, the leaves collected by the woven bag can be used as firewood or fertilizer. Furthermore, the woven bag is made of polypropylene, which not only makes it wear-resistant, heat-resistant, and weather-resistant, effectively improving its service life, but also allows rainwater to pass through the gaps in the woven bag, thereby increasing the bag's leaf-bearing capacity and improving the practical application effect of the invention.

[0021] In one embodiment of the present invention, the bottom of the discharge port 17 is provided with a U-shaped support plate 36; the lower end of the support plate 36 is hinged with a hook 361; the lower end of the machine body 1 is fixedly installed with a pulley 37; the upper end of the pulley 37 is provided with a pull rope 371; the pull rope 371 is in rolling contact with the pulley 37; the pull rope 371 is fixedly connected to the support plate 36; the hook 361 is used to hook woven bags.

[0022] In one embodiment of the present invention, a support cylinder 38 is provided between the pulley 37 and the discharge port 17; the support cylinder 38 is hinged to the bottom of the machine body 1; the surface of the support plate 36 has a slot 362; one end of the pull rope 371 near the support plate 36 passes through the support cylinder 38 and is fixedly connected to the support plate 36.

[0023] In one embodiment of the present invention, the slot 362 is horn-shaped; the support plate 36 is made of PTFE material; and a cavity 363 is formed inside the support plate 36. In operation, initially, the user installs a fixed hanging lug on the wall or ground. After installing the machine body 1, the user connects one end of the pull rope 371 to the support plate 36. The other end of the pull rope 371 passes through the support cylinder 38, and then the tension from the support cylinder 38 passes over the pulley 37, allowing the other end of the pull rope 371 to be released to the ground from the side of the pulley 37 away from the support cylinder 38. The user then hangs the upper end of the woven bag on the hook 361 at the lower end of the support plate 36, securing the woven bag to the lower end of the support plate 36. Since there are two support cylinders 38, both are hinged to the bottom of the machine body 1 and are fixedly connected. Each support cylinder 38 has a pull rope 371. When the user pulls the other end of the pull rope 371, the pull rope 371 on the pulley 37 pulls the support plate 36 upward, causing the support plate 36 to move closer to the support cylinder 38 under the stretching force. Since the fixed part of the pull rope 371 and the support plate 36 is located at the center of the slot 362 of the support plate 36, the rope will pull the support plate 36 and move the slot 362 to the support cylinder 38, allowing the support cylinder 38 to be inserted into the slot 362. By setting the slot 362 to be funnel-shaped, when the support plate 36 contacts the support cylinder 38, the support cylinder 38 can contact the funnel-shaped end of the support plate 36, causing the support cylinder 38 to move along the slot 362. The rounded chamfer at the flared end enters the slot 362. At this point, the support cylinder 38 is connected to the support plate 36. As the pull rope 371 is pulled, it causes the support plate 36 to continue rising, allowing the support plate 36 to drive the support cylinder 38 to rotate upwards along the hinge between the support cylinder 38 and the machine body 1 until the support plate 36 rotates to below the discharge port 17. At this point, the user secures the pull rope 371 to the hanging lug, thus fixing the support plate 36 below the discharge port 17. By making the support plate 36 with PTFE material, it has the advantages of a smooth surface and low friction. When the support plate 36 contacts the support cylinder 38, the friction between the support cylinder 38 and the inner wall of the slot 362 is reduced. The low friction facilitates the insertion of the support cylinder 38 into the slot 362. By providing a cavity 363 inside the support plate 36, the material of the support plate 36 can be reduced, lowering the manufacturing cost. On the other hand, the weight of the support plate 36 can be reduced, making it easier for the user to pull the support plate 36 up using the pull rope 371. Moreover, when the woven bag is full of leaves, the user can untie the pull rope 371 attached to the hanging ear to lower the support plate 36 and the woven bag, making it convenient for the user to replace the woven bag on the ground. This avoids the user climbing the roof and the risk of falling, ensuring user safety and effectively improving the practical application effect of the invention.

[0024] The specific workflow is as follows: During operation, the user fixes the unit 1 to the eaves and connects the drain pipe 13 to the outlet 12 of the unit 1. When rainwater flows down from the sloping roof, it washes leaves from the roof to the unit 1. The rainwater then enters the unit 1 through the filter 14 passing through the inlet 11. The rainwater flowing into the unit 1 then flows through the outlet 12 into the drain pipe 13, allowing the drain pipe 13 to discharge the rainwater. Because the unit 1 is in a semi-enclosed state, it can block the upper part of the inlet 11, preventing leaves from falling into the unit 1 and ensuring that the inlet 11 is not blocked by leaves. However, as leaves continue to be washed to the filter 14, the rainwater... As the mesh of filter 14 is continuously blocked, the operator controls the drive motor 16 to rotate the rotating column 15. This causes the toothed grooves 151 on the surface of the rotating column 15 to rotate. Since the mounting plate 2 on the surface of filter 14 engages with the toothed grooves 151 on the surface of the rotating column 15, the rotating column 15 can push the mounting plate 2 through the groove walls of the toothed grooves 151, causing the filter 14 to rotate around the rotating column 15. During the movement of the filter 14 within the machine body 1, the mounting plate 2 slides against the inner wall of the machine body 1. At this time, the mounting groove 22 is located on the side of the mounting plate 2 closest to the machine body 1. Therefore, during this sliding contact between the mounting plate 2 and the inner wall of the machine body 1... During the dynamic contact process, the push plate 21 in the mounting groove 22 is blocked by the inner wall of the body 1 and squeezes the connecting spring 221 near the bottom of the groove. The mounting plate 2 can push the push plate 21 inside the mounting groove 22 to move synchronously. At this time, the side of the push plate 21 away from the body 1 slides in contact with the body 1. When the mounting plate 2 on the surface of the filter screen 14 enters the water inlet 11, the mounting plate 2 no longer slides in contact with the body 1, so that the push plate 21 in the mounting groove 22 is no longer blocked by the body 1. Under the push of the restoring force of the connecting spring 221, the push plate 21 that has extended out of the mounting groove 22 can extend out of the water inlet 11. As the push plate 21 extends out of the inlet 11, the leaves blocked by the filter screen 14 will be between two adjacent push plates 21. As the filter screen 14 drives the push plate 21 to move continuously, the push plate 21 can push the leaves blocked by the filter screen 14 to move synchronously until the push plate 21 pushes the leaves blocked by the filter screen 14 to the unloading module. At this time, the outlet 12 is no longer blocked by the leaves, increasing the amount of water entering through the outlet 12. The unloading module can collect the leaves pushed by the push plate 21, preventing the leaves from accumulating on the sloping roof and preventing strong winds from blowing the accumulated leaves away on the sloping roof again, thus reducing the blockage of the filter screen 14 at the outlet 12 caused by the leaves.When the push plate 21 passes the unloading module, it contacts the body 1, causing the push plate 21 to squeeze the connecting spring 221 into the mounting groove 22 under the blocking force of the body 1. The leaves that are attached to the filter screen 14 due to the tension of the rainwater will be scraped off the filter screen 14 by the inner wall of the body 1, so that the body 1 cleans the surface of the filter screen 14. The cleaned filter screen 14 rotates around the rotating rod under the drive of the mounting plate 2 until the filter screen 14 that has entered the body 1 moves to the outlet 12 again. At this time, the filter screen 14 that has leaked out of the body 1 is not blocked by the leaves, thus improving the filtration effect of the filter screen 14. The claw pin 322 is made of PTFE material and is arc-shaped. The rotating column 15 drives the mounting plate 2 to move the filter belt and push plate 21 towards the discharge column 3. This causes the push plate 21 to push the leaves blocked by the filter belt to the discharge column 3. Since the discharge column 3 and the rotating column 15 are connected by a gear set 23, they rotate towards each other. When the leaves move between the discharge column 3 and the rotating column 15 under the push of the push plate 21, the discharge column 3 can push the leaves located between the discharge column 3 and the rotating column 15 through the extrusion plate 32. This allows the leaves to pass through the gap between the discharge column 3 and the rotating column 15 and move towards the discharge port 17, so that the leaves can fall through the discharge port 17. Inside the woven bag; by setting a squeezing plate 32, the squeezing plate 32 can extend out of the squeezing groove 31 under the push of the return spring 33, thereby increasing the length of the squeezing plate 32 extending out of the squeezing groove 31, thus increasing the range of the leaves around the discharge column 3 pushed by the squeezing plate 32 until the squeezing plate 32 pushes the leaves to the rotating column 15. At this time, the squeezing plate 32 contacts the rotating column 15 through the filter screen 14 attached to the surface of the rotating column 15, so that the rotating column 15 can squeeze the squeezing plate 32 to continuously compress the return spring 33 into the squeezing groove 31, so that the squeezing plate 32 in contact with the rotating column 15 can generate an effective pushing force on the leaves between the rotating column 15 and the discharge column 3, ensuring that the leaves are effectively pushed into the discharge port 17, improving the discharge effect of the discharge column 3, and the squeezing plate The cooperation between 32 and the return spring 33 not only increases the pushing range of the extrusion plate 32, but also prevents the extrusion plate 32 from being damaged by the extrusion of the rotating column 15. Through the setting of the claw nail 322, when the extrusion plate 32 extends out of the extrusion groove 31 and pushes the leaves around the discharge column 3, the claw nail 322 extends out of the circular groove 321 under the restoring force of the fixing spring 323. During the pushing process of the extrusion plate 32, leaves continuously accumulate on one side of the extrusion plate 32, causing the leaves near the end of the extrusion plate 32 away from the discharge column 3 to be squeezed out of the extrusion plate 32 by the accumulated leaves. The claw nail 322 can effectively block the leaves pushed by the extrusion plate 32, thereby increasing the pushing amount of the extrusion plate 32 on the leaves. When the extrusion plate... When the claw nail 322 rotates to a position close to the rotating column 15, the pressing plate 32 is blocked by the rotating column 15 and enters the pressing groove 31. A pressure sensor 35 embedded in the bottom of the pressing groove 31 can monitor whether the pressing plate 32 rotates to contact the filter screen 14. When the pressing plate 32 contacts the filter screen 14 attached to the surface of the rotating column 15, the pressing plate 32 presses the return spring 33 into the pressing groove 31. At this time, the return spring 33 exerts a pressing force on the pressure sensor 35. Upon detecting that the pressing plate 32 is in contact with the filter screen 14, the electromagnet 34 is energized, causing the electromagnet 34 to attract the claw nail 322 into the circular groove 321. This allows the leaves pierced by the claw nail 322 to be blocked by the pressing plate 32 and detach from the claw nail 322.This allows leaves pierced by the claw nail 322 to enter the discharge port 17 under the push of the extrusion plate 32. The side of the extrusion plate 32 with the circular groove 321 is set as an inclined surface. When the extrusion plate 32 rotates to the end of the discharge port 17, the inclined surface of the extrusion plate 32 contacts the end of the discharge port 17, causing the discharge port 17 to exert a squeezing force on the inclined surface of the extrusion plate 32. This squeezing force perpendicular to the inclined surface generates a component force perpendicular to the extrusion groove 31 on the extrusion plate 32. Under the push of this component force, the extrusion plate 32 drives the claw nail 322 and completely enters the extrusion groove 31. At this point, when the pressure sensor 35 senses that the pressure has reached the upper limit of the set value, the pressure sensor 35 transmits an electrical signal to the electromagnet 34, causing the electromagnet 34 to be de-energized. This continues until the extrusion plate 32 rotates and moves beyond the machine body 1. At this time, the claw nail 322 and the pressing plate 32 continuously extend out of the circular groove 321 and the pressing groove 31 under the push of the fixing spring 323 and the return spring 33, so that the claw nail 322 and the pressing plate 32 push the leaves; and by setting up a woven bag made of polypropylene material, on the one hand, the woven bag can collect the leaves, preventing the leaves from being blown to other roofs by strong winds, and the leaves collected by the woven bag can also be used as firewood or fertilizer for plants. On the other hand, the woven bag is made of polypropylene material, which not only makes the woven bag wear-resistant, heat-resistant, and weather-resistant, effectively improving the service life of the woven bag, but also allows rainwater to pass through the gaps in the woven bag, thereby increasing the woven bag's load-bearing capacity for leaves, thus improving the practical application effect of the invention. The system is improved; in the initial state, the user installs a fixed hanging lug on the wall or ground. After the machine body 1 is installed, the user fixes one end of the pull rope 371 to the support plate 36, and the other end of the pull rope 371 first passes through the support cylinder 38, and then the tension passing through the support cylinder 38 passes over the pulley 37, so that the other end of the pull rope 371 can be released to the ground from the side of the pulley 37 away from the support cylinder 38. Then the user hangs the upper end of the woven bag on the hook 361 at the lower end of the support plate 36, so that the woven bag is fixedly fitted on the lower end of the support plate 36. Since there are two support cylinders 38, both support cylinders 38 are hinged to the bottom of the machine body 1 and are fixedly connected. Moreover, each of the two support cylinders 38 has a pull rope 371. Therefore, when using... When the other end of the pull rope 371 is pulled, the pull rope 371 on the pulley 37 pulls the support plate 36 upwards, causing the support plate 36 to move closer to the support cylinder 38 under the stretching force. Since the fixed part of the pull rope 371 and the support plate 36 is located at the center of the slot 362 of the support plate 36, the rope pulls the support plate 36, causing the slot 362 to be positioned at the support cylinder 38, allowing the support cylinder 38 to be inserted into the slot 362. By setting the slot 362 to be funnel-shaped, when the support plate 36 contacts the support cylinder 38, the support cylinder 38 can contact the funnel-shaped end of the support plate 36, allowing the support cylinder 38 to enter the slot 362 along the rounded chamfer of the funnel-shaped end. At this time, the support cylinder 38 is connected to the support plate 36. As the pull rope 371 is continued to be pulled...The pull rope 371 causes the support plate 36 to continue rising, allowing the support plate 36 to drive the support cylinder 38 to rotate upwards along the hinge between the support cylinder 38 and the machine body 1 until the support plate 36 rotates to below the discharge port 17. At this point, the user secures the pull rope 371 to the hanging lug, thus fixing the support plate 36 below the discharge port 17. By making the support plate 36 with PTFE material, it has the advantages of a smooth surface and low friction. When the support plate 36 contacts the support cylinder 38, the low friction between the support cylinder 38 and the inner wall of the slot 362 facilitates the insertion of the support cylinder 38 into the slot 362. By creating a cavity 363 inside the support plate 36, the material used in the support plate 36 can be reduced, lowering manufacturing costs. Furthermore, the weight of the support plate 36 can be reduced, making it easier for the user to pull the support plate 36 upwards using the pull rope 371. When the woven bag is full of leaves, the user can untie the pull rope 371 attached to the hanging ear to lower the support plate 36 and the woven bag, allowing for easy bag replacement on the ground. This avoids the user having to climb onto the roof, preventing falls and ensuring user safety, thus effectively improving the practical application of the invention.
