Description
Technical Field
[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a fallen leaf recycling device for gardens. Background Technique
[0002] In the process of garden greening, fallen leaves are a recyclable resource. Effective utilization can reduce energy consumption and increase income. At present, the resource utilization of fallen leaves can usually be used for composting and biomass power generation. However, at present, most of the garden fallen leaf recycling and cleaning methods are manual, which not only has low efficiency but also high costs.
[0003] Some existing fallen leaf recycling devices have made certain progress in automatic recycling, but their actual utilization is less. This is mainly because their structures are complex, their volumes are large, and their actual use effects are poor. At the same time, in gardens, there are a large number of impurities such as stones and soil blocks, and the existing fallen leaf recycling devices are difficult to distinguish them. Content of the Utility Model
[0004] To solve at least one of the above problems, the utility model proposes a fallen leaf recycling device for gardens, which can separately recycle fallen leaves and impurities such as sand and gravel, improving its practicability; at the same time, this device has a small volume, a simple structure, a relatively low cost, and is easy to promote and use.
[0005] The technical solution of the utility model is: a fallen leaf recycling device for gardens, including a fan and a housing. The fan is arranged at the top of the housing. A storage chamber is arranged below the fan. A bottom plate is arranged at the lower part of the housing. An inclined baffle is arranged on one side of the housing. A temporary storage bucket is arranged on one side of the bottom plate close to the inclined baffle. A baffle is arranged between the storage chamber and the temporary storage bucket. A first air flow channel is formed between the inclined baffle and one side wall of the temporary storage bucket. A second air flow channel is arranged directly above the opening of the temporary storage bucket. The first air flow channel is sequentially communicated with the second air flow channel and the storage chamber, and the sizes of the first air flow channel, the second air flow channel, and the storage chamber increase in sequence. When in use, one end of the first air flow channel away from the second air flow channel faces the ground.
[0006] In one embodiment of the utility model, an L-shaped baffle is arranged at one end of the housing close to the fan, and the L-shaped baffle is used to prevent the materials coming from the second air flow channel from directly entering the fan interior.
[0007] In one embodiment of the utility model, rolling wheels are further arranged at the bottom of the bottom plate.
[0008] In one embodiment of the utility model, a rotating shaft is arranged between the inclined baffle and the housing. The inclined baffle can rotate around the rotating shaft, and the rotating shaft can fix the inclined baffle at a certain angle.
[0009] Further, the temporary storage bucket is detachably arranged on the bottom plate.
[0010] In an embodiment of the present utility model, several blocking needles are further arranged on the second air flow channel.
[0011] Further, a groove is arranged on the housing close to the second air flow channel, and a sealing block matching the groove is arranged at the same time. One end of the sealing block close to the second air flow channel is provided with a blocking needle, and the sealing block is detachably arranged.

Specific Embodiments
[0017] Next, the specific embodiments of the present utility model will be clearly and completely described in conjunction with the examples and the drawings. Obviously, the described examples are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0018] Such as Figures 1 to 2As shown in the figure, a fallen leaf recycling device for gardens includes a fan 9 and a housing 17. The fan 9 is provided at the top of the housing 17. A storage chamber 2 is provided below the fan 9. A bottom plate 1 is provided at the lower part of the housing 17. An inclined baffle 3 is provided on one side of the housing 17. A temporary storage bucket 4 is provided on one side of the bottom plate 1 close to the inclined baffle 3. A baffle 6 is provided between the storage chamber 2 and the temporary storage bucket 4. A first air flow channel 5 is formed between the inclined baffle 3 and one side wall of the temporary storage bucket 4. A second air flow channel 7 is provided directly above the opening of the temporary storage bucket 4. The first air flow channel 5 is sequentially connected to the second air flow channel 7 and the storage chamber 2, and the sizes of the first air flow channel 5, the second air flow channel 7, and the storage chamber 2 increase in sequence. During use, one end of the first air flow channel 5 away from the second air flow channel 7 faces the ground.
[0019] Specifically, regarding the internal structure of the housing 17, a fan 9 is provided at the upper part of one side. When the fan 9 is working, it sucks air inside the housing 17, causing the gas to flow from inside the housing 17 to the outside of the housing 17. Below the fan 9, there is a storage chamber 2 for storing the collected fallen leaves. To facilitate the treatment of the fallen leaves, a fallen leaf bucket 16 can be provided inside the storage chamber 2. When the fallen leaves in the fallen leaf bucket 16 reach a certain amount, the fallen leaf bucket 16 is taken out and the fallen leaves are recycled. For this reason, in this embodiment, a door 8 is provided on one side wall of the storage chamber 2. Through this door 8, the fallen leaf bucket 16 can be taken out. At the same time, to ensure the effect of the storage chamber 2, a sealing sleeve can be provided around the door 8. This sealing sleeve can be made of rubber and can greatly reduce the problem of gas entering the storage chamber 2 through the door 8.
[0020] The fan 9 provides the force required to adsorb fallen leaves and other sundries. The housing 17 is used to ensure that the force provided by the fan 9 will not disperse. At the same time, the housing 17 is also used for the installation of components such as the storage chamber 2, the fan 9, and the temporary storage bucket 16. To separate fallen leaves and sand and gravel, in this embodiment, a first air flow channel 5 and a second air flow channel 7 are provided, and it is specified that the size of the first air flow channel 5 is smaller than that of the second air flow channel 7. Since the two air flow channels are connected and the air volume per unit time is the same, the gas flow rate in the second air flow channel 7 is less than that in the first air flow channel 5. In such a case, sand and gravel with a larger density will settle in the second air flow channel 7. Since the temporary storage bucket 4 is below the second air flow channel 7, the sand and gravel will enter the temporary storage bucket 4 and be stored.
[0021] The same principle applies to the storage chamber 2 and the second air flow channel 7: Since the size of the storage chamber 2 is larger than that of the second air flow channel 7, the gas flow rate in the storage chamber 2 is slower, resulting in substances with a lower density such as fallen leaves also settling inside the storage chamber 2, thus completing the recycling of fallen leaves.
[0022] As for the specific dimensions of the first air flow channel 5, the second air flow channel 7, and the storage chamber 2, they are related to the power of the fan 9: the greater the power of the fan 9, the greater the dimensional difference among the three, and vice versa. However, the inventor found during the actual production process that considering the density of fallen leaves and sand and gravel, the size of the cross-section of the storage chamber 2 is at least 2.5 times that of the cross-section of the second air flow channel 7, and the size of the cross-section of the second air flow channel 7 is at least 1.5 times that of the cross-section of the first air flow channel 5. In such a case, it can be ensured that the sand and gravel and fallen leaves can enter the temporary storage bucket 4 and the storage chamber 2 respectively.
[0023] For the second air flow channel 7 and the storage chamber 2, in order to separate them, a baffle 6 is provided between the storage chamber 2 and the temporary storage bucket 4. The baffle 6 separates the storage chamber 2 and the temporary storage bucket 4, and also indirectly separates the second air flow channel 7 and the storage chamber 2, so that the air flow shows different flow velocities inside the second air flow channel 7 and the storage chamber 2.
[0024] When the device starts to work, under the action of the fan 9, the flow path of the air flow is successively the outside, the first air flow channel 5, the second air flow channel 7, the storage chamber 2, and the fan 9. Since the end of the first air flow channel 5 far from the second air flow channel 7 faces the ground, sundries such as sand and gravel and fallen leaves on the ground are sucked into the first air flow channel 5. When these sundries enter the second air flow channel 7, as the air flow velocity slows down, sand and gravel with a larger density settle into the temporary storage bucket 4, and fallen leaves and other sundries with a smaller density enter the storage chamber 2 through the second air flow channel 7. As the air flow velocity further decreases, these sundries with a smaller density settle inside the storage chamber 2, thus completing the recovery.
[0025] From the above recovery process, it can be seen that since the fan 9 is arranged above the storage chamber 2, when fallen leaves enter the storage chamber 2, some fallen leaves may be adsorbed on the fan 9, affecting the normal operation of the fan 9. To avoid this problem, an L-shaped baffle 10 is provided at one end of the housing 17 close to the fan 9. The vertical arm of the L-shaped baffle 10 is close to the second air flow channel 7, and its horizontal arm is arranged below the fan 9, so that the L-shaped baffle 10 can prevent the materials coming from the second air flow channel 7 from directly entering the fan 9, ensuring the normal operation of the fan 9.
[0026] In some cases, the ground not only includes sundries such as fallen leaves and gravel, but also has a small amount of soft plastic bags with relatively low density. The density of some plastic bags is lower than that of fallen leaves, and at the same time, their sizes are larger, which can easily affect the fan 9 and is also not conducive to the recycling of fallen leaves. To reduce the impact of plastic bags, in this embodiment, several blocking needles 12 are further provided on the second air flow channel 7. The lengths of these blocking needles 12 are relatively close to or equal to the cross-sectional length of the second air flow channel 7, and they are arranged at intervals. The interval is larger than the size of conventional fallen leaves, so that the fallen leaves will not be affected by the blocking needles, while due to the large size and softness of the plastic bags, they are easily blocked by the blocking needles 12. To more easily catch the plastic bags, some barbs can be provided on the blocking needles 12.
[0027] To facilitate the treatment of the plastic bags hanging on the blocking needles 12, a groove is provided on the housing close to the second air flow channel 7, and at the same time, a sealing block 11 matching the groove is provided. One end of the sealing block 11 close to the second air flow channel 7 is provided with a blocking needle 12, and the sealing block 11 is detachably arranged. When it is found that there is a certain amount of plastic bags on the blocking needles 12, after removing the sealing block 11, the plastic bags on the blocking needles 12 can be taken out.
[0028] The first air flow channel 5 is jointly determined by the inclined baffle 3 and the temporary storage bucket 4. For the temporary storage bucket 4, its position is fixed. At this time, if the inclined baffle 3 is also fixed, then the size of the first air flow channel 5 will be fixed. In some cases, the fallen leaves in some gardens are small, such as those in coniferous forests and grasslands, while the fallen leaves in some gardens are larger, such as those in broad-leaved forests. The inclined baffle 3 that can adjust the inclination angle can be applicable to more environments, and at the same time, it is relatively beneficial to reduce the power and energy consumption of the fan (currently, almost all fans can adjust the corresponding rotation speed gears and power, so as to adjust the air volume and wind speed). Therefore, in this embodiment, a rotating shaft 15 is provided between the inclined baffle 3 and the housing 17, and the inclined baffle 3 can rotate around the rotating shaft 15, and the rotating shaft 15 can fix the inclined baffle 3 at a certain angle. There are many such rotating shafts, such as the currently common damping rotating shafts, etc., which can achieve this purpose.
[0029] At the same time, since the temporary storage bucket 4 is used to store sundries such as gravel with high density, when it is stored to a certain amount, it needs to be taken out. Therefore, we set the temporary storage bucket 4 to be detachable. When the sundries in the temporary storage bucket 4 are stored to a certain amount, rotate the inclined baffle 3, and then take out the temporary storage bucket 4.
[0030] To facilitate the use of this device, corresponding rolling wheels 14 are further provided at the bottom of the bottom plate. Through the rolling wheels 14, this device can be moved more conveniently. The rolling wheels 14 can be conventional universal wheels. At the same time, to facilitate operation, a handrail 13 is also provided on the housing 17.
[0031] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to form equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
