Description

Technical Field

[0001] This invention belongs to the technical field of fallen leaf recycling devices, specifically an environmentally friendly garden fallen leaf recycling and processing device. Background Technology

[0002] In autumn and winter, many trees shed their leaves to protect themselves from the cold. During this leaf-fall season, sanitation workers and gardeners need to collect the fallen leaves from hedges, lawns, and roadsides, then either burn them or transport them to landfills. This not only causes air pollution but also results in the loss of organic matter. Fallen leaves are a resource; recycling and effectively utilizing them can reduce energy consumption.

[0003] Furthermore, fallen leaves will cover the roads around the garden. Since garden roads are often hard surfaces, the fallen leaves cannot decompose in time. Long-term residue will cause the fallen leaves to rot, which will not only affect the appearance of the road, but also obstruct pedestrians and may cause them to slip and fall.

[0004] Therefore, during garden maintenance, when there are many fallen leaves, it is often necessary to clean up the fallen leaves on the road. The usual cleaning methods are manual or automatic. Manual cleaning usually involves cleaners using sweeping tools to sweep up the fallen leaves on the road and then collecting and disposing of the swept leaves. This method is time-consuming, inefficient, and has high labor costs. Automatic cleaning methods involve operating automatic processing equipment, such as automatic leaf vacuum machines, which can absorb the fallen leaves on the road through ventilation and quickly complete the cleaning work.

[0005] However, existing automatic leaf suction machines operate on a non-contact basis. During rainy weather, the gaps between some fallen leaves and the road surface are quite moist, and mixed with soil erosion and other debris, causing the leaves to adhere tightly to the road surface and making it difficult for the automatic leaf suction machine to suck them in. As the automatic leaf suction machine continues to move forward during the cleaning process, fallen leaves that are not cleaned in time will stick to the road surface, resulting in incomplete leaf removal and affecting the appearance of the road surface. If the remaining adhered fallen leaves are cleaned manually, it will increase the cleaning cost and affect the cleaning efficiency of the road surface. Summary of the Invention

[0013] Preferably, the sidewall of the suction nozzle is provided with a crushing block, the end of which is sharp and concentrated in the gap between the combing blocks; the inner wall of the suction nozzle opening is uniformly provided with a guide groove, the end of which extends upward and faces the gap between the combing blocks.

[0014] Preferably, a separation plate is provided on the inner wall of the suction chamber, the separation plate dividing the internal area of ​​the suction chamber into a recovery area on the upper side of the separation plate and a separation area on the lower side of the separation plate, and separation holes are uniformly provided on the separation plate.

[0015] Preferably, the separation plate is elastically connected to the inner wall of the suction chamber, and a vibrator is installed on the separation plate, the start of which is controlled by an intelligent control system.

[0016] Preferably, the upper surface of the separation plate is uniformly provided with top rods, the top rods are vertically arranged, and the ends of the top rods are spherical.

[0017] Preferably, the separation plate has a hollow interior forming a gas guiding cavity, which is not connected to the separation hole, and the gas guiding cavity is connected to the outlet of the gas supply device through a gas supply pipe, and the gas supply device is installed in the side wall of the suction chamber;

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The environmentally friendly garden leaf recycling and processing device of the present invention involves activating a drive device connected to a cleaning roller at the opening of a suction nozzle, which drives the cleaning roller to rotate. The rotating cleaning roller causes cleaning strips evenly arranged on its surface to rotate, and the ends of the cleaning strips contact the fallen leaves on the road surface, thus sweeping away the fallen leaves. This causes relative movement between the fallen leaves and the road surface, thereby releasing the tight adhesion between the fallen leaves and the road surface. This allows the fallen leaves to be sucked in by the suction generated at the opening of the suction nozzle, resulting in a more thorough cleaning of the fallen leaves on the road surface.

[0022] 2. The environmentally friendly garden leaf recycling and processing device of the present invention allows the No. 1 fan and the No. 2 fan to start alternately. During the cleaning process, the fallen leaves first stay inside the suction chamber. During the stay of the fallen leaves in the suction chamber, the intense vibration causes the small and heavy debris such as soil and stones mixed in with the fallen leaves to be separated and fall to the bottom of the suction chamber. The large and light fallen leaves are recycled and sucked into the recycling bin. This achieves the separation of debris in the fallen leaves and avoids the hard debris such as stones mixed in with the fallen leaves from hindering the crushing and processing of the fallen leaves into green fertilizer during the later recycling process.

Detailed Implementation

[0032] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] An environmentally friendly garden leaf recycling and processing device is proposed. In urban gardens, a large number of trees are planted. As the weather changes, the increase in fallen leaves will cover the roads around the gardens. Since garden roads are often hard surfaces, the fallen leaves cannot decompose in time. Long-term residue will cause the fallen leaves to rot, which will not only affect the aesthetics of the roads, but also obstruct pedestrians and may cause them to slip and fall.

[0035] Therefore, during garden maintenance, when there are many fallen leaves, it is often necessary to clean up the fallen leaves on the road. The usual cleaning methods are manual or automatic. Manual cleaning usually involves cleaners using sweeping tools to sweep up the fallen leaves on the road and then collecting and disposing of the swept leaves. This method is time-consuming, inefficient, and has high labor costs. Automatic cleaning methods involve operating automatic processing equipment, such as automatic leaf vacuum machines, which can absorb the fallen leaves on the road through ventilation and quickly complete the cleaning work.

[0036] However, existing automatic leaf suction machines operate on a non-contact basis. During rainy weather, the gaps between some fallen leaves and the road surface are quite moist, and mixed with soil erosion and other debris, causing the leaves to adhere tightly to the road surface and making it difficult for the automatic leaf suction machine to suck them in. Furthermore, as the automatic leaf suction machine continues to move forward during the cleaning process, leaves that are not cleaned in time will stick to the road surface, resulting in incomplete leaf removal and affecting the appearance of the road. If the remaining adhered leaves are cleaned manually, it will increase the cleaning cost and affect the cleaning efficiency of the road surface.

[0037] To effectively solve the above problems, see the attached diagram in the instruction manual. Figure 1-7 As shown, an environmentally friendly garden leaf recycling and processing device includes an automatic leaf suction vehicle. The automatic leaf suction vehicle includes a vehicle body 1, a leaf suction machine body 11 and a recycling bin 12 installed on the vehicle body 1. The vehicle body 1 is equipped with moving wheels, which are connected to a motor. The rotation speed and direction of rotation are automatically controlled by an intelligent control system to facilitate the movement of the vehicle body 1 along a predetermined route. The intelligent control system is installed inside the leaf suction machine body 11 to control the operation of each component of the device. The intelligent control system here is the control system inside an existing automatic leaf suction machine. It can control the movement of each component by means of a pre-entered program, or it can be operated manually by a person in the side.

[0038] A suction nozzle 13 is provided on the front side of the vehicle body 1, and a suction pipe 14 is provided on the top of the suction nozzle 13. The suction pipe 14 is connected to the suction chamber 15 provided inside the leaf suction machine body 11. The top of the suction chamber 15 is connected to the inside of the recovery bin 12 through the recovery pipe 121. A first fan 151 is provided on the side wall of the suction chamber 15, and a second fan 122 is provided on the side wall of the recovery bin 12. Filters are provided at the air inlets of both the first fan 151 and the second fan 122. The first fan 151 and the second fan 122 are both existing air pumps that provide suction power inside the leaf suction machine, and their power is controlled by the intelligent control system.

[0039] A cleaning roller 16 is provided on the side wall of the opening of the suction nozzle 13. The cleaning roller 16 is rotatably connected to the side wall of the suction nozzle 13 through a rotating shaft 161 located in the middle. The rotating shaft 161 is connected to a drive device located inside the side wall of the suction nozzle 13. The drive device here can be a drive motor and is controlled by an intelligent control system. Cleaning strips 162 are uniformly provided on the surface of the cleaning roller 16. The cleaning strips 162 are made of elastic material.

[0040] Specific workflow: When it is necessary to clean up fallen leaves on the garden road, the automatic leaf suction vehicle of this application is transported to the garden road. Then, the predetermined cleaning route is input into the intelligent control system, and the moving wheels on the automatic leaf suction vehicle are controlled to start rotating, driving the vehicle body 1 to move along the road between gardens. During the movement, the opening of the suction nozzle 13 on the front side of the vehicle body 1 is close to the road surface, and the No. 1 fan 151 inside the leaf suction machine 11 starts to operate. The resulting suction effect is transmitted to the opening of the suction nozzle 13 through the suction pipe 14. The resulting suction effect sucks up the fallen leaves on the road surface directly in front of it. Then, the fallen leaves enter the suction chamber 15 through the suction pipe 14, thus cleaning up the fallen leaves on the road surface.

[0041] During this process, the drive device connected to the cleaning roller 16 located at the opening of the suction nozzle 13 is activated, causing the cleaning roller 16 to rotate. The rotating cleaning roller 16 causes the cleaning strips 162, which are evenly distributed on the surface, to rotate. The ends of the cleaning strips 162 contact the fallen leaves on the road surface and sweep them away. The friction generated by the rotation of the cleaning strips 162 causes relative movement between the fallen leaves and the road surface, which loosens the tight adhesion between the fallen leaves and the road surface, making it easier for the fallen leaves to be sucked in by the suction generated at the opening of the suction nozzle 13, thereby making the fallen leaves on the road surface cleaner.

[0042] The cleaning strip 162 is made of elastic material. When the cleaning strip 162 comes into contact with the road surface, the elastic deformation of the cleaning strip 162 reduces the force during the contact process, thus reducing damage to the road surface and the cleaning strip 162. Moreover, even on dirt roads, the cleaning strip 162 causes less damage to the road surface. It can effectively sweep away the fallen leaves adhering to the road surface, making the cleaning of fallen leaves on the road surface more thorough and efficient, improving the appearance of the road surface after cleaning, and making it easier for pedestrians to walk.

[0043] Furthermore, once the fallen leaves have entered and filled the suction chamber 15, the first fan 151 is shut down; the vehicle body 1 also stops moving, and the second fan 122 is started. The suction effect of the second fan 122 is transmitted through the recovery pipe 121, causing the fallen leaves inside the suction chamber 15 to be sucked into the recovery pipe 121 under the suction effect, and then enter the recovery bin 12 through the recovery pipe 121; after emptying the suction chamber 15, the second fan 122 is shut down again, and the first fan 151 and the vehicle body 1 are started to continue the cleaning work;

[0044] This allows the No. 1 fan 151 and the No. 2 fan 122 to start alternately, so that the fallen leaves first stay inside the suction chamber 15 during the cleaning process, and then are sucked into the recycling bin 12. During the time the fallen leaves stay in the suction chamber 15, the intense vibration causes small and heavy debris such as soil and stones mixed in with the fallen leaves to be separated and fall to the bottom of the suction chamber 15, while the large and light leaves are recycled and sucked into the recycling bin 12, thus achieving the separation of debris from the fallen leaves. Regularly cleaning the debris at the bottom of the suction chamber 15 reduces the amount of debris in the fallen leaves in the recycling bin 12, reduces the weight of the fallen leaves, and facilitates the recycling of more fallen leaves. At the same time, it avoids the hard debris such as stones mixed in with the fallen leaves from hindering the crushing and processing of the fallen leaves into green fertilizer during the later recycling process. Making the fallen leaves into green fertilizer also improves resource utilization efficiency, reduces carbon emissions caused by indiscriminate burning, and is more in line with the development direction of urban environmental protection.

[0045] Example 2:

[0046] Based on Embodiment 1, as shown in the accompanying drawings of the specification. Figures 4-6 As shown, a cleaning block 163 is provided at the end of the cleaning strip 162. The end of the cleaning block 163 is sharp and inclined. Cleaning spikes 164 are evenly provided at the end of the cleaning block 163. The cleaning spikes 164 are bent into hook shapes and are elastic.

[0047] Specific workflow: Based on the specific workflow in Example 1, when the cleaning strip 162 rotates with the cleaning roller 16, the cleaning block 163 at the end of the cleaning strip 162 contacts the fallen leaves on the road surface. Because the end is sharp, the contact friction between it and the surface of the fallen leaves is large, further pushing the fallen leaves to slide relative to the road surface. Then, they are sucked into the suction nozzle 13 by the suction. Furthermore, the cleaning spikes 164 located at the end of the cleaning block 163, which are hook-shaped, can hook or even penetrate into the fallen leaves when they come into contact with them. Thus, as the cleaning strip 162 moves, the hooked fallen leaves move with the cleaning strip 162, detach from the road surface, and detach from the cleaning block 163 under the high-intensity suction, and are sucked in and recovered. This makes the fallen leaves on the road surface more fully recovered, improves the cleaning efficiency, and reduces the amount of manual cleaning work.

[0048] Example 3:

[0049] Based on Embodiment 2, as shown in the accompanying drawings of the specification. Figures 4-6 As shown, the suction nozzle 13 has evenly arranged combing blocks 131 on its sidewall, and the gap between the combing blocks 131 is larger than the width of the cleaning blocks 163; hook blocks 132 are evenly arranged on the sidewall of the combing blocks 131 near the cleaning roller 16, and the ends of the hook blocks 132 are bent upward; crushing blocks 133 are arranged on the sidewall of the suction nozzle 13, and the ends of the crushing blocks 133 are sharp and concentrated in the gap between the combing blocks 131; guide grooves 134 are evenly arranged on the sidewall of the opening of the suction nozzle 13, and the ends of the guide grooves 134 extend upward and face the gap between the combing blocks 131.

[0050] Specific workflow: Based on the specific workflow in Embodiment 2, when the cleaning strip 162 rotates past the side wall of the suction nozzle 13, the end of the cleaning strip 162 will contact the side wall, and at the same time, it will clean the fallen leaves adhering to the inner wall of the suction nozzle 13, keeping the inside of the suction nozzle 13 unobstructed; at the same time, because the inner wall of the suction nozzle 13 is provided with combing blocks 131, when the cleaning strip 162 passes through the part provided with combing blocks 131, the cleaning block 163 at the end of the moving cleaning strip 162 slides along the inside of the suction nozzle 13 and is embedded in the gap between the combing blocks 131; in this way, during the process of the combing blocks 131 and the cleaning blocks 163 sliding back and forth, the fallen leaves that may be trapped in the gap between the combing blocks 131 and the end of the cleaning blocks 163 are cleaned and recycled under the action of suction;

[0051] Furthermore, when the cleaning strip 162 passes through the gap between the combing blocks 131, the large leaf pieces sandwiched between adjacent cleaning strips 162 come into contact with the combing blocks 131. The combing blocks 131 are provided with hook blocks 132, which can hook the large fallen leaves adhering to the cleaning strips 162, so that the fallen leaves are removed from the cleaning strips 162. Moreover, the end of the hook block 132 is tilted upward, so the fallen leaves that are hooked down can more smoothly detach from the hook block 132 under the action of the suction and be recycled.

[0052] Furthermore, the cleaning block 163, sliding in the gaps between the combing blocks 131, is limited by the combing blocks 131 on both sides, maintaining a stable movement trajectory. It then contacts the evenly distributed broken blocks 133 in the gaps between the combing blocks 131. The broken blocks 133 pass through the gaps between the cleaning spikes 164, breaking and removing small pieces of fallen leaves mixed in between the cleaning spikes 164, thereby effectively cleaning the cleaning spikes 164. In this way, by effectively cleaning the cleaning strip 162 and the cleaning blocks 163 on the cleaning strip 162, it is ensured that they can perform their cleaning function normally and effectively clean the fallen leaves on the road surface.

[0053] Furthermore, during the startup of the No. 1 fan 151, when the drawn-in airflow enters the suction nozzle 13, a portion of the airflow flows through the guide groove 134 on the side wall of the suction nozzle 13. The airflow along the guide groove 134 converges and is guided into the gaps of the combing blocks 131, flushing away the leaf fragments remaining in the gaps of the combing blocks 131, ensuring the normal operation of the broken blocks 133 inside the combing blocks 131. In addition, the airflow guided by the guide groove 134 flows on the inner wall of the suction nozzle 13, flushing away the leaves adhering to the inner wall, further preventing the accumulation and blockage of leaves at the opening of the suction nozzle 13, and ensuring the unobstructed flow of the suction nozzle 13.

[0054] Example 4:

[0055] Based on Embodiment 3, as shown in the accompanying drawings of the specification. Figures 2-3 , Figure 7 As shown, a separation plate 17 is provided on the inner wall of the suction chamber 15. The separation plate 17 divides the internal area of ​​the suction chamber 15 into a recovery area 152 on the upper side of the separation plate 17 and a separation area 153 on the lower side of the separation plate 17. Separation holes 171 are evenly provided on the separation plate 17. The separation plate 17 and the inner wall of the suction chamber 15 are elastically connected. Specifically, the elastic connection can be achieved by using an elastic material for the connection part between the separation plate 17 and the inner wall of the suction chamber 15. A vibrator is installed on the separation plate 17. The vibrator can be a miniature vibration motor, which is installed inside the separation plate 17. The start of the vibrator is controlled by an intelligent control system.

[0056] Specific workflow: Based on the specific workflow in Example 3, the No. 1 fan 151 causes the fallen leaves to be sucked into the suction chamber 15 by the suction pipe 14 and stay there temporarily. At this time, the fallen leaves are concentrated on the separation plate 17. The intelligent control system can control the vibrator to start, and the vibrator drives the separation plate 17 to start vibrating relative to the side wall of the suction chamber 15. The fallen leaves located on the upper side of the separation plate 17 shake under the vibration. Small and heavy debris such as stones mixed in the fallen leaves move to the lower side of the fallen leaves and finally flow out through the separation holes 171 evenly arranged on the separation plate 17 and move to the lower separation area 153.

[0057] This reduces the amount of debris mixed with the fallen leaves remaining in the upper recycling area 152. After the second fan 122 is started, the debris is sucked into the recycling pipe 121 by the suction, leaving the recycling area 152 and entering the recycling bin 12. The recycling bin 12 can be equipped with the compression or crushing devices commonly found in existing fallen leaf recycling and processing equipment to crush and compress the incoming fallen leaves, saving space and facilitating the later processing into green manure after preliminary processing. The removal of small but heavy debris such as stones can reduce the potential damage to the processing equipment during the fallen leaf processing, making the crushing and processing of fallen leaves smoother.

[0058] Example 5:

[0059] Based on Embodiment 4, as shown in the accompanying drawings of the specification. Figures 2-3 , Figure 7 As shown, top rods 172 are evenly arranged on the upper surface of the separation plate 17. The top rods 172 are vertically arranged and the ends of the top rods 172 are spherical. The interior of the separation plate 17 is hollow to form an air guiding cavity 173. The air guiding cavity 173 is not connected to the separation hole 171, and the air guiding cavity 173 is connected to the air outlet of the air supply device through the air supply pipe 175. The air supply device here can be a miniature air pump device in the side wall of the separation zone 153. The top rods 172 are hollow inside and are connected to the interior of the air guiding cavity 173. Air outlet holes 174 are evenly arranged on the side wall of the top rods 172. The air outlet holes 174 near the top of the top rods 172 open upwards, and the air outlet holes 174 near the bottom open horizontally.

[0060] Specific workflow: Based on the specific workflow in Example 4, after the fallen leaves are sucked into the suction chamber 15, they fall onto the upper side of the top rod 172. The top rod 172 lifts the fallen leaves, maintaining a large gap between the fallen leaves and the upper side of the separation plate 17, so that the debris in the fallen leaves can fall smoothly into the gap on the upper side of the separation plate 17, and then fall into the lower separation zone 153 through the separation plate 17. During the vibration process, the end of the top rod 172 agitates the accumulated fallen leaves, further promoting the separation between the fallen leaves and the debris, and recovering the debris.

[0061] Furthermore, during the operation of the No. 2 fan 122, the intelligent control system controls the start of the air supply equipment, causing the airflow discharged from the air supply equipment to flow into the air delivery pipe 175, and then into the interior of the top rod 172, flowing out from the air outlets 174 evenly arranged on the side wall of the top rod 172; the airflow flowing out from the air outlets 174 on the side wall of the top rod 172 impacts the fallen leaves located in the gaps between the top rods 172, causing the fallen leaves in the gaps to be impacted by the upward airflow, causing the fallen leaves in the gaps to detach from the gaps of the top rods 172 under the impact of the airflow, and then be attracted by the suction effect of the recovery pipe 121 and sucked upward, thereby cleaning the fallen leaves trapped in the gaps between the top rods 172;

[0062] Furthermore, the air outlet 174 located near the bottom of the top rod 172 is horizontally arranged. The outflowing airflow impacts the debris accumulated on the upper surface of the separation plate 17, causing the debris on the upper surface of the separation plate 17 to move faster under the action of vibration and airflow impact. Then, it enters the separation hole 171 and moves to the lower separation zone 153 for recycling, thereby thoroughly cleaning the debris on the upper side of the separation plate 17.

[0063] Example 6:

[0064] Based on Embodiment 5, as shown in the accompanying drawings of the specification. Figure 2 As shown, a discharge port 154 is provided at the bottom of the separation zone 153, and a sealing door 155 is provided inside the discharge port 154. A control motor can be installed at the rotating connection part of the sealing door 155. The control motor is controlled by the intelligent control system. In this way, the rotation of the sealing door 155 can be achieved by starting the control motor, thereby realizing the automatic opening and closing of the discharge port 154.

[0065] Specific workflow: Based on the specific workflow in Example 5, when debris enters the separation zone 153, because the distance from the opening of the recycling pipe 121 is large and the suction effect of the second fan 122 is blocked by the separation plate 17, the debris in the separation zone 153 is relatively stable. During a period of recycling, when a lot of debris accumulates in the separation zone 153, the vehicle body 1 is moved to a position away from the road surface and the closed door 155 is opened, so that the debris recycled in the separation zone 153 leaves from the discharge port 154. This clears the separation zone 153, reduces the load on the vehicle body 1, and facilitates the continuation of the cleaning work.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
