Description

Technical Field

[0001] This utility model relates to the field of cleaning rake technology, and in particular to a leaf-clearing rake for garden maintenance. Background Technology

[0002] A garden rake is a tool frequently used by gardeners. It is mainly used to clear fallen leaves from garden grass, lawns, and other areas, creating a clean and comfortable environment for people.

[0003] Current leaf removal rakes for garden maintenance mostly remove fallen leaves from the turf by using their teeth. However, these rakes still have the following problems in actual use: The current method of using a leaf-clearing rake requires moving the rake up and down and back and forth to remove fallen leaves. During operation, the rake teeth will carry the fallen leaves back through them, causing them to become stuck on the rake teeth. This requires manual removal and frequent pulling of the rake teeth to clean them, which affects the efficiency of the operation. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a leaf-clearing rake for garden maintenance, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a leaf-clearing rake for garden maintenance, comprising a connecting plate, a plurality of connecting lugs fixedly connected to one side of the connecting plate, rake teeth fixedly connected to the center of each of the connecting lugs at the end away from the connecting plate, a drive shaft rotatably connected to the center of the plurality of connecting lugs, a plurality of cleaning push rods fixedly connected to one side of the drive shaft, and pulling lugs inclined towards the side away from the connecting plate fixedly connected to both sides of the middle of the drive shaft, a connecting shaft rotatably connected to the center of the bottom of two of the pulling lugs, a traction rope fixedly connected to the center of the connecting shaft, and a connecting rod fixedly connected to the center of one side of the connecting plate. The device includes a rake handle with a non-slip grip fixedly connected to the end of the rake handle away from the connecting plate. A guide groove is provided at the center of the bottom of the non-slip grip. A hollow structure is provided at the center of the rake handle. The guide groove is connected to the interior of the rake handle. A pull plate is slidably connected to the inner wall of the guide groove. One end of the pull plate is located on the inner wall of the rake handle. A traction rope passes through the connecting plate and is located at the center of the inner wall of the rake handle. The end of the traction rope away from the connecting shaft is fixedly connected to the top of the pull plate. Several return springs are sleeved on the outer wall of the drive shaft. The two ends of the return springs are fixedly connected to the connecting lug and the drive shaft, respectively. Several cleaning push rods are raised to the top of several rake teeth rods under the winding of the return springs.

[0007] Preferably, in any of the above embodiments, the plurality of cleaning push rods are located at the center between the plurality of rake teeth rods, the length of the plurality of cleaning push rods is greater than the length of the plurality of rake teeth rods, and the ends of the plurality of rake teeth rods are bent downwards.

[0008] The technical effect achieved by the above solution is that several cleaning push rods pass between several rake teeth rods, which can completely push and clean the leaves hanging on the rake teeth rods.

[0009] Preferably, in any of the above schemes, the angle between the two pulling ears and the plurality of cleaning push rods is an acute angle structure, and the position of the end of the plurality of rake teeth rods away from the connecting plate is lower than the bottom surface of the connecting plate.

[0010] The technical effect achieved by adopting the above solution is that: the fallen branches and leaves in the lawn can be raked out by a number of rake teeth, and the angle between the pull ear and a number of cleaning push rods ensures that the pull ear has a larger range of pulling and rotating.

[0011] Preferably, in any of the above embodiments, the width of the guide channel is smaller than the diameter of the inner wall of the rake rod, the top of the pull plate is in contact with the inner wall of the rake rod, and the bottom end of the pull plate extends through the guide channel to the bottom of the anti-slip grip.

[0012] The technical effect achieved by adopting the above solution is to prevent the pull plate from detaching from the inner wall of the rake rod from the guide channel.

[0013] Preferably, in any of the above solutions, the length of the guide channel is greater than the stroke of the connecting shaft being pulled by the traction rope, and the length of the traction rope is equal to the length between the connecting shaft and the pull plate.

[0014] The technical effect achieved by adopting the above solution is that the sliding distance in the guide channel can ensure that one end of the connecting shaft is fully pulled, so that it can drive the transmission shaft and several cleaning push rods to flip downward.

[0015] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. This garden maintenance leaf-clearing rake uses several rake teeth to remove fallen leaves and branches from the lawn. When too many leaves are stuck on the rake teeth, simply pull the pull plate backward from the grip position of the non-slip handle. This pulls the connecting shaft via the traction rope, causing the pull lug to rotate towards the connecting plate. This rotation drives the drive shaft, causing several cleaning push rods on one side of the drive shaft to flip downward. These push rods then pass between the rake teeth, pushing the leaves stuck on the rake teeth down quickly. This eliminates the need to manually pull the rake teeth back, improving work efficiency.

[0016] 2. This garden maintenance leaf-clearing rake, through the winding force of the reset spring, allows the drive shaft to automatically rewind after the leaves strung on the rake teeth are cleared and the pull plate is released, thus retracting several cleaning push rods.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0020] Example 1: As Figures 1 to 3 As shown, a leaf-clearing rake for garden maintenance includes a connecting plate 1. Several connecting lugs 2 are fixedly connected to one side of the connecting plate 1. Rake teeth 5 are fixedly connected to the center of each connecting lug 2 at the end away from the connecting plate 1. A drive shaft 3 is rotatably connected to the center of the connecting lugs 2. Several cleaning push rods 4 are fixedly connected to one side of the drive shaft 3. Pulling lugs 10, inclined towards the side away from the connecting plate 1, are fixedly connected to both sides of the middle of the drive shaft 3. A connecting shaft 11 is rotatably connected to the center of the bottom of two pulling lugs 10. A traction rope 12 is fixedly connected to the center of the connecting shaft 11. A rake rod 7 is fixedly connected to the center of one side of the connecting plate 1. The rake rod 7 is located away from the connecting plate. One end of the rake rod 7 is fixedly connected to a non-slip handle 8. A guide channel 14 is provided at the center of the bottom of the non-slip handle 8. A hollow structure 13 is provided at the center of the rake rod 7. The guide channel 14 is connected to the interior of the rake rod 7. A pull plate 9 is slidably connected to the inner wall of the guide channel 14. One end of the pull plate 9 is located on the inner wall of the rake rod 7. A traction rope 12 passes through the connecting plate 1 and is located at the center of the inner wall of the rake rod 7. The end of the traction rope 12 away from the connecting shaft 11 is fixedly connected to the top of the pull plate 9. Several return springs 6 are sleeved on the outer wall of the drive shaft 3. The two ends of the several return springs 6 are fixedly connected to the connecting ear plate 2 and the drive shaft 3 respectively. Several cleaning push rods 4 are raised to the top of several rake tooth rods 5 under the winding of the return springs 6.

[0021] As an optional technical solution of this utility model, a plurality of cleaning push rods 4 are respectively located at the center between a plurality of rake teeth rods 5. The length of the plurality of cleaning push rods 4 is greater than the length of the plurality of rake teeth rods 5. The ends of the plurality of rake teeth rods 5 are bent downward so that the plurality of cleaning push rods 4 pass through the plurality of rake teeth rods 5, and can completely push down the leaves hanging on the plurality of rake teeth rods 5.

[0022] As an optional technical solution of this utility model, the angle between the two pull ears 10 and the several cleaning push rods 4 is an acute angle structure, and the position of the several rake teeth 5 away from the connecting plate 1 is lower than the bottom surface of the connecting plate 1, so that the bottom of the rake teeth 5 protrudes to facilitate contact with the lawn surface. The several rake teeth 5 can rake out the dead branches and leaves that have fallen into the lawn. The angle between the pull ears 10 and the several cleaning push rods 4 ensures that the pull ears 10 have a larger range of pulling and rotating.

[0023] As an optional technical solution of this utility model, the width of the guide channel 14 is smaller than the diameter of the inner wall of the rake rod 7, the top of the pull plate 9 is in contact with the inner wall of the rake rod 7, and the bottom end of the pull plate 9 extends through the guide channel 14 to the bottom of the anti-slip grip 8, thereby preventing the pull plate 9 from detaching from the inner wall of the rake rod 7 from the guide channel 14.

[0024] As an optional technical solution of this utility model, the length of the guide channel 14 is greater than the stroke of the connecting shaft 11 being pulled by the traction rope 12. The length of the traction rope 12 is equal to the length between the connecting shaft 11 and the pull plate 9, so that the sliding distance in the guide channel 14 can ensure that one end of the connecting shaft 11 is fully pulled, so that it can drive the transmission shaft 3 and several cleaning push rods 4 to flip downward.

[0025] A leaf-clearing rake for garden maintenance works on the following principle: 1) The dead branches and leaves that have fallen into the lawn can be raked out by using several rake teeth 5; 2) When too many fallen leaves are inserted into the rake tooth rod 5, simply pull the pull plate 9 backward from the grip position of the anti-slip handle 8, and pull the connecting shaft 11 through the traction rope 12; 3) This causes the pull ear 10 to rotate toward the connecting plate 1, which in turn causes the transmission shaft 3 to rotate. This causes several cleaning push rods 4 on one side of the transmission shaft 3 to flip downwards, so that the cleaning push rods 4 pass between several rake rods 5, thereby pushing the leaves hanging on the rake rods 5 down and achieving rapid cleaning.

[0026] In summary, this garden maintenance leaf-clearing rake can remove fallen leaves and branches from the lawn using several rake teeth 5. When too many leaves are stuck on the rake teeth 5, simply pull the pull plate 9 backward from the grip position of the non-slip handle 8. This pulls the connecting shaft 11 via the traction rope 12, causing the pull lug 10 to rotate towards the connecting plate 1. This, in turn, rotates the drive shaft 3, causing several cleaning push rods 4 on one side of the drive shaft 3 to flip downward. The cleaning push rods 4 then pass between the rake teeth 5, pushing the leaves stuck on the rake teeth 5 down, achieving rapid cleaning without the need to manually pull back the rake teeth 5, thus improving work efficiency. The rewinding force of the return spring 6 allows the drive shaft 3 to automatically rewind after the leaves stuck on the rake teeth 5 are removed and the pull plate 9 is released, causing the cleaning push rods 4 to retract.

[0027] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
