[0001] The present application relates to the technical field of cleaning parts, and in particular to a fallen leaf collector. Background Art

[0002] There are usually many trees planted in parks or family courtyards. When the trees shed their leaves, many leaves will fall on the ground. In order to keep the ground clean, people regularly clean the fallen leaves on the ground. In order to improve the cleaning efficiency of fallen leaves, people have invented a leaf collector to collect fallen leaves on the ground.

[0003] In the related art, see Figure 1 and Figure 2 The leaf collector includes a carrier box 1 and a collection bag 242, wherein the collection bag 242 is connected to the carrier box 1; wherein, a moving part 3 is provided on the outer wall of the carrier box 1, wherein the moving part 3 is a roller, and a cleaning fan blade 23 is provided in the carrier box 1, wherein a rotating shaft 22 is provided through the cleaning fan blade 23, wherein both ends of the rotating shaft 22 are rotatably provided through the carrier box 1, and both ends of the rotating shaft 22 are respectively inserted into two rollers, wherein the rotating shaft 22 is fixedly connected to the rollers. When the collector is used, people push the carrier box 1, so that the carrier box 1 rolls on the ground through the rollers, and when the rollers roll, the rotating shaft 22 is driven to rotate, so that the rotating shaft 22 drives the cleaning fan blade 23 to rotate, so that the cleaning fan blade 23 pushes the leaves on the ground into the collection bag 242.

[0047] An embodiment of the present application discloses a fallen leaf collector.

[0048] Reference Figure 3 The fallen leaf collector includes a carrying box 1 and a leaf collecting mechanism 2. The leaf collecting mechanism 2 is connected to the carrying box 1 and is used to collect leaves on the ground. The carrying box 1 is provided with a moving part 3, which drives the carrying box 1 to move, thereby driving the leaf collecting mechanism 2 to move.

[0049] See also Figure 3 and Figure 4 The leaf collecting mechanism 2 includes a driving member 21, a rotating shaft 22 drivingly connected to the driving member 21, a cleaning blade 23 connected to the rotating shaft 22, and a collecting member 24 for receiving leaves. The driving member 21 drives the rotating shaft 22 to rotate, so that the cleaning blade 23 rotates and moves the leaves on the ground, so that the leaves are pushed into the collecting member 24.

[0050] Among them, the driving member 21 is a motor, and the driving member 21 is fixedly connected to the outer wall of the carrying box 1; the bottom surface of the carrying box 1 is provided with a accommodating cavity 11, the rotating shaft 22 is located in the accommodating cavity 11, and the two ends of the rotating shaft 22 are rotatably penetrated through the cavity wall of the accommodating cavity 11, the driving member 21 is transmission-connected with the rotating shaft 22, so that the driving member 21 drives the rotating shaft 22 to rotate on the carrying box 1; the cleaning fan blades 23 are connected to the rotating shaft 22, so that the rotating shaft 22 drives the cleaning fan blades 23 to rotate; the collecting member 24 is detachably connected to the outside of the carrying box 1, so that the collecting member 24 can be removed from the carrying box 1.

[0051] In addition, the carrying box 1 is provided with a leaf channel 12 connected to the accommodating chamber 11 , and the leaf channel 12 is connected to the outer wall of the carrying box 1 close to the collecting member 24 , so that the cleaning fan blades 23 push the leaves on the ground from the leaf channel 12 into the collecting member 24 .

[0052] See also Figure 5 Furthermore, the driving member 21 is connected to the rotating shaft 22 through a gear set 25. The gear set 25 includes a driving gear 251 and a driven gear 252. Both the driving gear 251 and the driven gear 252 are located in the accommodating chamber 11. The output shaft of the driving member 21 extends into the accommodating chamber 11 and is fixedly connected to the driving gear 251, so that the driving member 21 drives the driving gear 251 to rotate; the driven gear 252 is fixedly sleeved on the rotating shaft 22, and the driven gear 252 is meshed with the driving gear 251, so that when the driving gear 251 rotates, the driven gear 252 is driven to rotate, and the driven gear 252 drives the rotating shaft 22 to rotate. It is worth noting that in this embodiment, the rotating shaft 22 is a square rod, and the parts at both ends of the rotating shaft 22 connected to the carrier box 1 are round rods.

[0053] When the collector collects leaves, the driving member 21 is started, and the driving member 21 drives the rotating shaft 22 to rotate through the gear set 25, and the rotating shaft 22 drives the cleaning blades 23 to rotate, so that the cleaning blades 23 move the leaves on the ground and push the leaves into the leaf channel 12, so that the leaves pass through the leaf channel 12 and enter the collecting member 24.

[0054] See also Figure 6 and Figure 7 The cleaning blade 23 is provided with a fixing groove 232 , and the rotating shaft 22 is passed through the fixing groove 232 , so that the cleaning blade 23 rotates together with the rotating shaft 22 .

[0055] In order to improve the firmness of the connection between the cleaning blade 23 and the rotating shaft 22, the cleaning blade 23 is provided with a locking member 4, and the cleaning blade 23 is fixed to the rotating shaft 22 by the locking member 4. The cleaning blade 23 has a connecting shaft 231 in the middle, and a fixing groove 232 is formed on the connecting shaft 231, and the fixing groove 232 is connected to one of the circumferential side surfaces of the connecting shaft 231.

[0056] See also Figure 7 and Figure 8 A set of opposite side surfaces of the connecting shaft 231 are integrally provided with a limiting block 233. The locking member 4 is plate-shaped. The locking member 4 is provided with a limiting groove 41 for the limiting block 233 to slide through. The limiting groove 41 runs through the two end surfaces of the locking member 4 in the length direction. The limiting block 233 abuts against the groove wall of the limiting groove 41, so that the locking member 4 is not easy to fall off from the connecting shaft 231.

[0057] In this embodiment, a plurality of limit blocks 233 are disposed on a side surface of the connecting shaft 231 , and two adjacent limit blocks 233 are disposed at the same distance.

[0058] See also Figure 8 and Fig. 9 The back of the locking member 4 is provided with an unlocking slot 42 for the limit block 233 to pass through and slide out. The unlocking slot 42 is connected to the limit slot 41. The width of the unlocking slot 42 is slightly larger than the width of the limit block 233, so that the limit block 233 can pass through the unlocking slot 42.

[0059] The locking member 4 is provided with a positioning block 43 , which is integrally arranged at one end of the locking member 4 in the length direction. When the locking member 4 is locked, the positioning block 43 abuts against the limiting block 233 .

[0060] The front of the locking member 4 is provided with windows 44 intersecting the limiting groove 41. The number of the windows 44 is the same as that of the limiting block 233, and the width of the windows 44 is greater than that of the limiting block 233. At the same time, the windows 44 and the unlocking grooves 42 are arranged alternately, so that the state of the limiting block 233 can be conveniently viewed through the windows 44, and the limiting block 233 can be conveniently observed to slide out of the unlocking groove 42. When the locking member 4 is connected to the connecting shaft 231, the plurality of limiting blocks 233 correspond to the plurality of windows 44, and the limiting blocks 233 can be seen from the windows 44 from the front of the locking member 4. When the locking member 4 moves and the limiting blocks 233 cannot be seen from the windows 44, the limiting blocks 233 correspond to the unlocking groove 42, and the limiting blocks 233 can slide out of the unlocking groove 42.

[0061] When the locking member 4 is in use, the locking member 4 is slidably sleeved on the limit block 233, and the limit block 233 slides in the limit groove 41 until the positioning block 43 abuts against the limit block 233 at the edge. At this time, the limit block 233 appears in the window 44, and the locking member 4 fixes the connecting shaft 231 on the rotating shaft 22.

[0062] Furthermore, in order to prevent the connecting shaft 231 from shaking on the rotating shaft 22, the locking member 4 is integrally provided with two abutment blocks 45, which protrude from the side surface of the limiting groove 41. When the locking member 4 is connected to the connecting shaft 231, the abutment blocks 45 are embedded in the fixing groove 232, and the abutment blocks 45 abut against the rotating shaft 22, so that the connection between the connecting shaft 231 and the rotating shaft 22 is stable.

[0063] See also Fig.10 and Fig.11 The moving member 3 is a roller, which includes an outer wheel 31 and an inner wheel 32. The inner wheel 32 is connected to the carrier box 1. The outer wheel 31 is rotatably sleeved on the inner wheel 32, so that the outer wheel 31 and the inner wheel 32 can rotate relative to each other; and the outer diameter of the outer wheel 31 is larger than the outer diameter of the inner wheel 32. When the roller is used, the outer wheel 31 abuts against the ground and rolls on the ground. In this embodiment, two rollers are provided, and the two rollers are respectively located on both sides of the carrier box 1. The carrier box 1 is supported by the rollers and driven to move.

[0064] See also Fig.11 and Fig.12 The carrier box 1 is provided with an adjustment component 5, through which the height of the roller on the carrier box 1 is adjusted. The adjustment component 5 includes a connecting rod 51, a sliding block 52 and a locking screw 53. The two ends of the connecting rod 51 are respectively fixedly connected to the inner wheels 32 of the two rollers, so that the rollers are connected to the carrier box 1 through the connecting rod 51; the sliding block 52 is slidingly connected to the carrier box 1, and the connecting rod 51 is fixedly penetrated on the sliding block 52, so that when the sliding block 52 slides on the carrier box 1, it drives the connecting rod 51 to move together; the locking screw 53 passes through the carrier box 1 and is threadedly connected to the sliding block 52, and the sliding block 52 is fixed on the carrier box 1 through the locking screw 53, so that the sliding block 52 is not easy to move on the carrier box 1.

[0065] Among them, the upper end surface of the carrying box 1 is provided with a sliding groove 13 for the sliding block 52 to slide. In this embodiment, the upper end surface of the carrying box 1 is an arc surface, so the sliding groove 13 is also arc-shaped. When the sliding block 52 slides in the sliding groove 13, the height of the sliding block 52 on the carrying box 1 changes, so that the height of the connecting rod 51 changes, and then the height of the roller changes.

[0066] The carrier box 1 is provided with a clearance groove 14, which is provided at the bottom of the sliding groove 13, the clearance groove 14 is connected to the accommodating cavity 11, and the length of the clearance groove 14 is the same as that of the sliding groove 13, and the locking screw 53 is penetrated in the clearance groove 14 and slides in the clearance groove 14.

[0067] When the sliding block 52 is connected to the carrying box 1, the locking screw 53 penetrates the clearance groove 14 from the wall of the accommodating cavity 11 and then is screwed into the sliding block 52, so that the locking screw 53 and the sliding block 52 are connected by threads, and the sliding block 52 is fixed on the carrying box 1 by the locking screw 53.

[0068] See also Fig.13The sliding block 52 includes a sliding portion 521 and a locking portion 522. The connecting rod 51 is inserted into the sliding portion 521, and the sliding portion 521 slides in the sliding groove 13.

The locking portion 522 is located on the side of the sliding portion 521 away from the carrier box 1, and the locking portion 522 is provided with a threaded hole 524 for the locking screw 53 to pass through. When the locking screw 53 is connected to the sliding block 52, the locking screw 53 passes through the through hole 523 of the sliding portion 521 and then is screwed into the threaded hole 524, so that the locking screw 53 and the locking portion 522 are connected by threads.

[0069] When the sliding block 52 is connected to the carrying box 1, the locking screw 53 passes through the clearance groove 14 and then enters the through hole 523 of the sliding part 521, and then passes through the through hole 523 and is screwed into the threaded hole 524; when the sliding block 52 is disassembled from the carrying box 1, the sliding part 521 is rotated to separate the locking screw 53 from the sliding part 521, thereby removing the sliding part 521 from the carrying box 1.

[0070] See also Fig.11 and Fig.12 In addition, the inner wheel 32 is coaxial and fixedly penetrated with a fixed shaft 33, and one end of the fixed shaft 33 penetrates into the outer wheel 31, and the fixed shaft 33 is rotatably connected with the outer wheel 31, so that the fixed shaft 33 and the outer wheel 31 can rotate relative to each other; a guide groove 15 is opened on the carrier box 1, and one end of the fixed shaft 33 away from the outer wheel 31 is slidably penetrated on the guide groove 15, and when the sliding block 52 drives the roller to move on the carrier box 1, the fixed shaft 33 slides in the guide groove 15.

[0071] At the same time, both ends of the rotating shaft 22 are respectively inserted into the two inner wheels 32. When the adjusting assembly 5 drives the roller 3 to move on the carrying box 1, the inner wheels 32 rotate along the rotating shaft 22 as the central axis, so that the rotation of the inner wheels 32 is more stable.

[0072] See also Fig.14 The collecting member 24 includes a fixing frame 241 and a collecting bag 242. The fixing frame 241 is surrounded by metal rods. The edge of the collecting bag 242 is sleeved on the fixing frame 241. The fixing frame 241 and the collecting bag 242 form a collecting cavity 243 for placing leaves.

[0073] The outer side wall of the carrying box 1 is provided with a hook 16 , and the fixing frame 241 is hung on the hook 16 , so that the collecting member 24 is connected to the carrying box 1 .
