Description

Technical Field

[0001] This utility model relates to the field of garden technology, specifically a leaf collection device for garden maintenance. Background Technology

[0002] Garden maintenance refers to the routine upkeep, repair, prevention and repair of catastrophic damage, and reinforcement, improvement or expansion measures taken to improve the quality of use, aesthetic effect and service level of gardens to ensure their normal use.

[0003] Chinese invention patent CN113863198B, published on April 15, 2025, discloses a leaf collector, belonging to the field of cleaning component technology. It includes a carrier box with a movable component and a leaf-collecting mechanism connected to the carrier box. The leaf-collecting mechanism includes sweeping blades for agitating leaves on the ground, a driving component for rotating the sweeping blades, and a collecting component for receiving and collecting leaves. In use, the movable component moves the carrier box, thereby moving the leaf-collecting mechanism. Simultaneously, the driving component activates the sweeping blades, causing them to rotate. The sweeping blades agitate the leaves on the ground, pushing them into the collecting component, thus completing the leaf collection. The driving component also increases the rotation speed of the sweeping blades, making it easier for them to push leaves into the collecting component.

[0004] However, the aforementioned disclosed solutions have the following shortcomings: Existing leaf collection devices use fan blades to scrape the leaves, which is only suitable for smooth, flat surfaces and not for leaves that have fallen on grass. They cannot separate the leaves from the grass and cannot effectively collect leaves that are different in color from the grass. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing leaf collection devices, which use fan blades to scrape fallen leaves, are only suitable for smooth, flat surfaces and are not suitable for leaves that have fallen on grass. They cannot separate fallen leaves from the grass and cannot effectively collect leaves that are different in color from the grass. This invention provides a leaf collection device for garden maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] This utility model discloses a leaf collection device for garden maintenance, comprising a collection cover; a movable unit at the lower end of the collection cover; partitions fixedly connected at intervals to the lower opening of the collection cover; connecting pipes fixedly connected to the partitions; a fan fixedly connected to the corresponding connecting pipe on the collection cover; a baffle fixedly connected to the partitions; an open pipe rotatably connected inside the collection cover; an open sleeve sleeved to the open pipe; a motor fixedly connected to one end of the open pipe; a connecting pipe fixedly connected to the other end of the open pipe; an output pipe fixedly connected to the lower end of the connecting pipe; multiple T-junctions fixedly connected to the output pipe; and a collection container inserted between the baffles and partitions.

[0008] The leaf collection device for garden maintenance provided by this utility model has the following beneficial effects:

[0009] 1. This utility model, when used in a garden, supplies power to a fan and motor. The fan's rotation generates negative pressure, which absorbs air from near the ground through a baffle and connecting pipe. Lighter fallen leaves are attracted and moved upwards. At the same time, the air pressure inside the collection hood is increased. Then, the high-pressure air enters the connecting pipe and output pipe through the open pipe and perforated sleeve, and is then discharged through multiple tee pipes and blown towards the ground, blowing up damp and heavier fallen leaves. Combined with the negative pressure inside the baffle and connecting pipe, the air velocity is increased, allowing fallen leaves on the ground and in the grass to be blown up and collected. The fallen leaves enter between the baffle and the collection hood with the flowing air, and then contact the perforated sleeve, blocking the holes on the surface of the perforated sleeve. Then, under the rotation of the perforated sleeve, the fallen leaves are driven downwards and then contact the inner surface of the collection hood, scraping off the fallen leaves. Since the fallen leaves are no longer on the path of the high-speed airflow, they fall into the collection container under the action of gravity for centralized collection.

[0010] 2. This utility model uses a flexible hose so that the end of the hose can be in contact with the ground. When blowing air, it can blow up the fallen leaves from the ground, move them, and collect them. It achieves the dual function of blowing and inhaling air, so that fallen leaves in the grass can also be blown up and collected, resulting in a good collection effect of fallen leaves in the grass.

[0020] Please see Figure 1-4As shown, a leaf collection device for garden maintenance includes a collection cover 1; a movable unit is provided at the lower end of the collection cover 1; partitions 6 are fixedly connected to the lower opening of the collection cover 1 at intervals; connecting pipes 8 are fixedly connected to the partitions 6; a fan 9 is fixedly connected to the collection cover 1 corresponding to the connecting pipes 8; a baffle 12 is fixedly connected to the partitions 6; an open pipe 10 is rotatably connected inside the collection cover 1; an open sleeve 11 is sleeved on the open pipe 10; a motor 15 is fixedly connected to one end of the open pipe 10; a connecting pipe 16 is fixedly connected to the other end of the open pipe 10; an output pipe 17 is fixedly connected to the lower end of the connecting pipe 16; multiple tee pipes 18 are fixedly connected to the output pipe 17; a collection container 13 is inserted between the baffle 12 and the partitions 6. In use, power is supplied to the fan 9 and the motor 15 in the garden. The fan 9 rotates to generate negative pressure, which absorbs air from near the ground through the partitions 6 and the connecting pipes 8, resulting in lighter leaves. The fallen leaves are adsorbed and moved upwards; at the same time, the air pressure inside the collection hood 1 increases. Then, the high-pressure air enters the connecting pipe 16 and the output pipe 17 through the open pipe 10 and the perforated sleeve 11, and then is discharged through multiple three-way pipes 18 and blown to the ground, blowing up the damp and heavier fallen leaves. Combined with the negative pressure in the baffle 6 and the connecting pipe 8, the air velocity is increased, so that the fallen leaves on the ground and in the grass can be blown up and collected. The fallen leaves enter between the baffle 12 and the collection hood 1 along with the flowing air, and then contact the perforated sleeve 11 to block the holes on the surface of the perforated sleeve 11. Then, under the rotation of the perforated sleeve 11, the fallen leaves are driven to rotate downwards and then contact the inner surface of the collection hood 1 to scrape off the fallen leaves. Then, the position of the fallen leaves is no longer on the path of the high-speed flowing air, and then they fall into the collection container 13 under the action of gravity for centralized collection.

[0021] The output port of the three-way pipe 18 is connected to a flexible hose 19. The end of the flexible hose 19 can be made to fit against the ground, so that when blowing air, it can blow up from the ground, move and collect fallen leaves, and achieve the dual function of blowing and inhaling. This allows fallen leaves that have fallen into the grass to be blown up and collected, resulting in a good collection effect of fallen leaves in the grass.

[0022] The lower end of the collection cover 1 is fixed with a toothed plate 20 corresponding to the partition 6. The toothed plate 20 is inserted deep into the grass to comb the grass and expose the movement path of the fallen leaves, so that the fallen leaves can be blown up and collected by the dual action of blowing and suction.

[0023] A handle 14 is fixed to the outer surface of the collection container 13, which allows the collection container 13 to be easily inserted into and pulled out of the baffle 12 and partition 6 to transfer the collected fallen leaves.

[0024] The mobile unit includes multiple casters 4 that roll on the ground; the casters 4 are fixed to threaded shafts 3; the threaded shafts 3 are threadedly fitted with a frame 2; the frame 2 is fitted onto the collection cover 1. By adjusting the height of the threaded shafts 3 on the frame 2, the distance between the frame 2 and the collection cover 1 and the ground can be adjusted, thus adapting to grass of different heights.

[0025] The threaded shaft 3 is threaded with multiple nuts 5. The multiple nuts 5 are located on the upper and lower sides of the sleeve frame 2, so that the threaded shaft 3 can be stably passed through the sleeve frame 2 and fixed, and the height can be adjusted to adapt to garden use with different grass heights.
