Description

Technical Field

[0001] The present invention mainly relates to the technical field of garden cleaning, and specifically to a garden leaf recycling device. Background Art

[0002] A garden is a beautiful natural environment and recreation area created by applying engineering techniques and artistic means in a certain area through ways such as transforming the terrain, planting trees, flowers and plants, constructing buildings, and arranging garden paths. It is called a garden and stands out in traditional Chinese architecture. The classical garden architecture has made significant achievements.

[0003] Generally, many kinds of plants such as trees, flowers and plants are planted in the garden. The fallen leaves of these trees, flowers and plants on the ground can easily lead to the ugliness of the garden landscape. Especially in autumn and winter, many garden plants will produce a large amount of fallen leaves. These fallen leaves are important participants in the ecological cycle. Cleaning and recycling them can not only make the garden more beautiful, but also make full use of them as nutrients for plant growth. The existing methods for cleaning garden fallen leaves are mainly manual cleaning, but manual cleaning has low efficiency and high cost. Moreover, after rain or in the area covered by the sprinkler in the garden irrigation, the fallen leaves are attached to the ground due to the action of water, which will greatly increase the cleaning difficulty. Conventional cleaning cannot fully clean the fallen leaves. The existing fallen leaf cleaning and recycling devices can effectively clean the fallen leaves on dry ground, but the cleaning effect on wet ground is also not good. When cleaning the soft road surface near the trees in the garden, it is also easy to suck in too much soil and other substances into the device, and it cannot clean targeted according to different road conditions. Summary of the Invention

[0004] To solve the deficiencies of the prior art, the present invention provides a garden leaf recycling device, which can set different cleaning modes according to different road conditions, effectively clean the fallen leaves on various road conditions, including cleaning and recycling the fallen leaves on the wetland road surface with the greatest cleaning difficulty, and can minimize the damage to the road surface that may be caused during the cleaning process, and help to improve the service life of the machine.

[0019] An electric push rod 21 is provided between the lifting platform 2 and the box body 1, swing arms 22 are symmetrically and rotatably installed on both sides of the bottom of the lifting platform 2, a cleaning roller 3 is rotatably installed at the end of the swing arm 22, a cleaning brush is provided on the cleaning roller 3, a return torsion spring and a limit block are provided at the rotation connection between the swing arm 22 and the lifting platform 2, and the movable angle between the swing arm 22 and the horizontal plane is 0 - 50°; a micro motor for driving the cleaning roller 3 to rotate is provided on the swing arm 22 on one side of the cleaning roller 3.

[0020] An air inlet channel 40 is formed in the middle of the lifting platform 2, and the telescopic pipe 4 is connected to the edge of the air inlet channel 40.

[0021] A crushing drive motor 60 is fixedly installed in the box body 1. The output shaft of the crushing drive motor 60 is connected to the rotating shaft of the crushing cutter bar 6. An outer support rod 61 is fixedly connected to the outer end of the crushing cutter bar 6. A brush 62 is fixedly installed outside the outer support rod 61. A plurality of inertial rods 63 are rotatably installed on the rotating shaft of the crushing cutter bar 6. The inertial rods 63 have no power drive. When the crushing drive motor 60 drives the crushing cutter bar 6 to rotate, a speed difference will be generated with the inertial rods 63, thereby shredding the fallen leaves. The inertial rods 63 and the crushing cutter bar 6 are arranged at intervals. The inertial rods 63 will rotate to a certain extent due to the extrusion and frictional force of the fallen leaves between the inertial rods 63 and the crushing cutter bar 6. However, due to no power drive, its rotation speed will always be unequal to that of the crushing cutter bar 6, thereby generating a speed difference to shred the fallen leaves. The crushing drive motor 60 rotates periodically and variably to improve the shredding effect.

[0022] A filter window 50 is provided in the crushing chamber 5 corresponding to the position of the circulation fan 7; the brush 62 is used to scrape off the fallen leaves accumulated on the surface of the filter window 50 due to air flow adsorption.

[0023] Two groups of conduit adjusting devices 9 are symmetrically arranged at the bottom of the box body 1. The conduit adjusting device 9 includes a control board 91. Two gas conduits 8 on the same side penetrate and are fixedly installed in the control board 91. A vertical connecting rod 92 is rotatably installed between the control board 91 and the box body 1. An inclined connecting rod 93 is rotatably installed between the control board 91 and the lifting platform 2. Threaded sleeves 94 capable of adjusting the length of the connecting rod are provided in the middle of the vertical connecting rod 92 and the inclined connecting rod 93. By adjusting the lengths of the vertical connecting rod 92 and the inclined connecting rod 93, the preset angle of the bifurcated air outlet 10 can be adjusted, and the conduit adjusting device 9 will also automatically adjust the air outlet angle as the height of the lifting platform 2 changes. The control board 91 is in the shape of a long rectangular plate and will avoid the moving space of the universal wheels 101. The lower air outlet of the bifurcated air outlet 10 is used to blow away the water attached to the road surface or blow up the fallen leaves, so that the cleaning brushes on the surface of the cleaning roller 3 can timely capture or brush up the fallen leaves. The upper air outlet of the bifurcated air outlet 10 is used to blow away the fallen leaves that have not been separated in time from the upper surface of the cleaning roller 3 into the air inlet channel 40 to be captured.

[0024] The structure of the screw conveyor 11 includes a conveying channel 111. The conveying channel 111 is fixedly arranged in the box body 1. A screw blade 112 is rotatably installed in the conveying channel 111. A conveying drive motor 113 is provided at the bottom of the conveying channel 111.

[0025] The upper part of the fallen leaf recycling bin 13 is provided with an opening 131. Handles 132 are provided on both sides of the fallen leaf recycling bin 13. A guiding inlet 133 is provided at the bottom inside the fallen leaf recycling bin 13. A leather plug with a cross-shaped opening is installed in the guiding inlet 133. Under normal circumstances, the leather plug is in a closed state. After the fallen leaf recycling bin 13 is installed in the box body 1, the top of the screw conveyor 11 will push open the cross-shaped opening of the leather plug in the guiding inlet 133, enabling the crushed fallen leaves to enter the recycling bin.

[0026] Universal wheels 101 and driving wheels 102 are respectively provided on both sides of the bottom of the box body 1. A driving motor 103 is provided on one side of the driving wheel 102. A hand push rod 104 is fixedly provided on one side of the box body 1. A box cover 105 is movably installed on the top of the box body 1. A lower battery pack 106 and an upper battery pack 107 are respectively arranged inside the box body 1; the arrangement of the battery packs will avoid other structures, such as the screw conveyor 11, the crushing driving motor 60, etc.

[0027] A control device and a charging interface are further provided on the outer surface of the device. A power adapter for charging the battery packs is provided inside the box body 1. The control device is a control device based on a single-chip microprocessor. Several control buttons are provided on the control device. An operator can control the operation of the device through the control device.

[0028] The control device is electrically connected to components such as the electric push rod 21, the battery packs, the crushing driving motor 60, the circulation fan 7, and the conveying driving motor 113.

[0029] When this device is in use, the operator turns on the device to make it move forward through the control device. The control device will control the driving motor 103 to rotate at a low speed to drive the device to move forward stably. The operator can control the forward direction of the device through the hand push rod 104. When reaching the area where fallen leaves need to be cleaned and recycled, turn on the fallen leaf cleaning and recycling work of this device. The control device will first control the lifting platform 2 to descend a certain height so that the cleaning roller 3 contacts the ground and has a certain pressure. Different working modes can be selected in the control device. For example, the cement ground mode: on hardened road surfaces such as cement ground, the lifting platform 2 descends a relatively large height, and the cleaning roller 3 has a relatively large pressure on the ground, which can effectively clean fallen leaves. Soft ground and gravel ground mode: Generally, such ground does not have a large adsorption force on fallen leaves, and at the same time, the ground structure is easy to be scraped up. In this mode, the lifting platform 2 descends a relatively small height, the pressure between the cleaning roller 3 and the ground is relatively small, and the rotation speed of the cleaning roller 3 is appropriately reduced, and at the same time, the speed of the circulating air flow is reduced. On the basis of effectively cleaning fallen leaves, the damage to the road surface and the inhalation of non-fallen leaf substances are reduced, and the abnormal wear of the machine caused by non-fallen leaf substances in the machine is reduced, and the service life of the machine is improved. The wetland / dry land function can also be superimposed in the above working modes. In the hardened wetland mode, the height of the lifting platform 2 is appropriately reduced to improve the cleaning power. In the non-hardened wetland mode, the height of the lifting platform 2 is appropriately increased, etc. When encountering an uneven road surface or foreign objects, the swing arm 22 will swing by overcoming the torsion of the torsion spring at the rotating shaft, thereby preventing the cleaning roller 3 from colliding strongly with the uneven road surface or foreign objects and being damaged. After the lifting platform 2 descends to the specified height according to different working modes, the cleaning roller 3 starts to rotate. The two cleaning rollers 3 rotate in opposite directions, and their rotation can push and rub the fallen leaves towards the middle of the device. The circulating fan 7 starts to work. The air flow passes through the air inlet channel 40 and the telescopic pipe 4 from the lower middle part of the device and is sucked into the crushing cavity 5, and then passes through the circulating fan 7, the gas duct 8, and the bifurcated air outlet 10 and returns to the vicinity of the cleaning roller 3 at the lower part of the device, thus forming a circulating air flow path and continuously bringing the fallen leaves into the crushing cavity 5. The filter window 50 provided on the air inlet side of the circulating fan 7 can effectively filter the fallen leaves. The fallen leaves retained here will enter the conveying channel 111 under the action of the brush 62. The fallen leaves in the crushing cavity 5 will also continuously enter the conveying channel 111 under the action of the rotational centrifugal force and then be conveyed to the fallen leaf recycling box 13 for collection. When the capacity of the fallen leaf recycling box 13 is almost full, open the box cover 105, take out the fallen leaf recycling box 13 and dump it or replace it with a new fallen leaf recycling box 13. Thus, the work of cleaning and recycling garden fallen leaves can be completed quickly, efficiently and labor-savingly.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
