Description

Technical Field

[0001] The invention relates to the technical field of lawn mowing, in particular to a multifunctional lawn mowing device. Background Art

[0002] In the landscaping industry, lawn mowing is a crucial part of daily maintenance. Traditional lawn mowing devices typically consist of a basic structure, such as a trimmer and a roller, designed to quickly cut the grass. However, these devices suffer from significant operational deficiencies. First, when cutting grass blades, the trimmer generates a large amount of dust, which not only pollutes the environment but can also affect the health of the operator. Existing technologies struggle to effectively suppress dust, often relying on manual sprinkling or simple spraying, resulting in water waste, uneven spraying, and inability to uniformly cover the mowing area. Second, cut grass clippings need to be cleaned to prevent accumulation and rotting. However, conventional systems lack effective collection and transport mechanisms, resulting in random scattering of clippings, increasing the burden of subsequent cleanup. Even some devices equipped with collection functions fail to dehydrate the clippings promptly, resulting in heavy, bulky, and easily rancid clippings, hindering resource recovery and environmentally friendly disposal. Furthermore, existing dehydration components are rudimentary in design, and the extrusion-based dehydration method is inefficient, causing clippings to stick to the equipment and cause frequent blockages, impacting continuous operation. The lack of a water recovery and reuse mechanism further exacerbates water consumption and operational costs. These issues collectively hinder the efficiency, environmental friendliness, and sustainability of landscaping operations.

[0003] Therefore, there is an urgent need for a multifunctional pruning device that can integrate dust suppression, transmission, dehydration and recycling functions in one, simultaneously reducing dust, efficiently collecting grass clippings and realizing automatic dehydration and drying during the pruning process, while avoiding component adhesion, ensuring smooth operation and efficient use of resources, so as to improve the overall efficiency and environmental friendliness of garden maintenance. Summary of the Invention

An inner ring 18 is provided between the multiple connecting rods 21, and the lower end of the inner ring 18 is fixedly connected to the fixed tube 12 through a fixing frame 17.

[0042] A plurality of first teeth 19 are processed on the rear side of the inner ring 18, and a plurality of second teeth 20 are processed on the front side of the inner ring 18.

The inner plate 26 is connected to the receiving plate 24 by multiple springs 25, and one end of the inner plate 26 is in sliding contact with the inner edge of the cylinder wall of the fixed cylinder 12.

[0045] The trimming assembly includes two trimming knives 30 rotatably arranged in the lower end of the trimmer 1. The two trimming knives are symmetrically arranged on the left and right. The upper ends of the rotating shafts of the trimming knives 30 are concentrically fixed with pulleys, and the two pulleys are connected by a first transmission belt 3.

[0046] A motor 2 is fixed inside the trimmer 1 , and an output shaft of the motor 2 is fixedly connected concentrically with one of the pulleys.

[0047] Specifically, two grass gathering plates 28 are fixed to the lower end of the trimmer 1 , the distance between the front portions of the two grass gathering plates 28 is greater than the distance between the rear portions, and the two pruning knives 30 are located between the front portions of the two grass gathering plates 28 .

[0048] The spray assembly includes a spray head 31, which is fixed to the lower end of the trimmer 1 behind the two pruning blades 30. An elastic airbag 7 is fixed in the trimmer 1. A liquid storage tank 10 is fixed in the trimmer 1 below the fixed cylinder 12. The liquid storage tank 10 is connected to the elastic airbag 7 through a first connecting tube 27, and the elastic airbag 7 is connected to the spray head 31 through a second connecting tube 271.

[0049] A liquid inlet check valve is installed on the first connecting pipe 27 , and a liquid outlet check valve is installed on the second connecting pipe 271 .

[0050] The upper end of one of the pulleys is eccentrically connected to a connecting plate 4, which is rotatably connected to one end of a movable plate 5. The movable plate 5 passes through the support plate 36, and the movable plate 5 is slidingly connected to the support plate 36. The support plate 36 is fixed in the trimmer 1, and the other end of the movable plate 5 is fixed with an extrusion plate 6, which is in contact with the elastic airbag 7.

[0051] The upper end of the liquid storage tank 10 is fixedly connected to a funnel 11 . The upper end of the funnel 11 is fixedly connected to the lower end of the fixed cylinder 12 . The funnel 11 is connected to a water outlet 32 ​​of the fixed cylinder 12 .

[0052] The rear end of the transmission component is tilted upward and extends into the trimmer 1. The transmission component includes a belt conveyor 8. A plurality of salvaging components are fixed to the outside of the transmission belt of the belt conveyor 8.

[0053] Each salvaging assembly includes a plurality of grass hooking rods 9, and the plurality of grass hooking rods 9 are evenly distributed in the width direction of the conveyor belt.

[0054] A plurality of scraping rods 14 are fixed to the upper end of the fixed cylinder 12 . The scraping rods 14 are staggered with the grass hooking rods 9 . The scraping rods 14 are fixed to the fixed cylinder 12 at the front side of the feed port 35 .

[0055] A baffle 13 is fixed to the fixed cylinder 12 at the rear side of the feed port 35 .

[0056] Transmission wheels are concentrically fixed on the driven roller and the rotating plate 15 of the belt conveyor 8 , and the driven roller and the transmission wheels on the rotating plate 15 are connected by a second transmission belt 16 .

[0057] During operation, the motor 2 and belt conveyor 8 are activated to propel the device across the lawn to be mowed. The motor 2 then drives one of the trimming blades 30 to rotate, and the other trimming blade 30 rotates accordingly under the action of the first transmission belt 3. The rotating trimming blades 30 trim the lawn, and the grass clippings produced by the trimming blades 30 are located between the two grass-grazing plates 28.

[0058] During the rotation of the pruning knife 30, the connecting plate 4 drives the movable plate 5 and the squeezing plate 6 to reciprocate. The reciprocating movement of the squeezing plate 6 intermittently squeezes the elastic airbag 7. When the elastic airbag 7 is squeezed, the liquid inlet one-way valve on the first connecting pipe 27 is closed, and the liquid outlet one-way valve on the second connecting pipe 271 is opened. The water in the elastic airbag 7 enters the nozzle 31 through the second connecting pipe 271 and is then sprayed onto the lawn, thereby preventing the cutting knife from generating a large amount of dust when trimming the grass on the lawn.

[0059] When the elastic airbag 7 is restored, the liquid outlet check valve on the second connecting pipe 271 is closed, and the liquid inlet check valve on the first connecting pipe 27 is opened, and the water in the liquid storage tank 10 enters the elastic airbag 7 through the first connecting pipe 27. By intermittently squeezing the elastic airbag 7, water can be intermittently sprayed from the nozzle 31 onto the lawn, which can reduce the amount of dust generated when the device mows the lawn.

[0060] After the belt conveyor 8 is started, the conveyor belt drives the multiple salvaging components to rotate. During the movement of this device, the multiple grass hooking rods 9 of the salvaging components move the grass clippings between the two grass gathering plates 28 onto the conveyor belt and are transported by the conveyor belt. The grass clippings transported by the conveyor belt are blocked by the blocking rod and enter the fixed cylinder 12 through the feed port 35 of the fixed cylinder 12. The baffle 13 can block the grass clippings that fall off the conveyor belt, ensuring that all grass clippings that fall off the conveyor belt can enter the fixed cylinder 12.

[0061] During the rotation of the conveyor belt, the rotating plate 15 rotates. During the rotation of the rotating plate 15, the multiple connecting rods 21, the multiple gears 22, the multiple arc blocks 23 and the multiple telescopic plates revolve counterclockwise around the axis of the rotating plate 15.

[0062] like Figure 11 As shown, in the counterclockwise direction, the arc block 23 on the left side of the fixing frame 17 is the first rotating block, and the remaining arc blocks 23 are the second rotating block, the third rotating block, etc.; the connecting rod 21 corresponding to the first rotating block is the first rod, and the remaining connecting rods 21 are the second rod, the third rod, etc.; the telescopic plate corresponding to the first rod is the first plate, and the remaining telescopic plates are the second plate, the third plate, etc.

[0063] When the first rotating block is located in the arc-shaped groove of the fixing frame 17, the first rod and the first plate cannot rotate around the axis of the first rod. At this time, the gear 22 on the second rod is engaged with the first teeth 19. Since the multiple first teeth 19 can make the gear 22 rotate continuously, the second block, the second rod and the second plate can rotate around the axis of the second rod during the revolution. The torsion spring on the second rod accumulates force. As the second plate rotates around the axis of the second rod, the space between the first plate and the second plate becomes smaller, and the first plate and the second plate can squeeze the grass clippings between them. After the grass clippings between the first plate and the second plate are squeezed, the water in the grass clippings is squeezed out and enters the liquid storage tank 10 through the filter screen 33 and the funnel 11 in the water outlet 32 ​​in turn.

[0064] When the first block is rotated out of the arc groove and the gear 22 on the second rod is separated from the first tooth 19, the second block, the second rod and the second plate rotate and return to their original position under the elastic force of the torsion spring on the second rod.

[0065] During the rotation of the rotating plate 15 , the space between two adjacent telescopic plates will be reduced successively, so that the grass clippings in the fixed cylinder 12 can be squeezed out, ensuring that the water attached to the grass clippings in the fixed cylinder 12 is squeezed out and reused.

[0066] After the grass clippings are squeezed between two adjacent telescopic plates, as the rotating plate 15 and the telescopic plate rotate, when the squeezed grass clippings correspond to the discharge opening 34 , the squeezed grass clippings are discharged into the collection trough 29 through the discharge opening 34 .

[0067] When the first block is rotated out of the arc groove, the first rod, the first block and the first plate can rotate on their own. When the gear 22 on the first rod engages with the second teeth 20, the plurality of second teeth 20 can cause the gear 22 to rotate intermittently. Therefore, during the orbital process of the first block, the first rod and the first plate, the first rod, the gear 22 on the first rod and the first plate can swing intermittently in the fixed cylinder 12, so that grass clippings attached to the first plate can be separated from the first plate, thereby preventing grass clippings from sticking to the first plate.

[0068] During the rotation of the rotating plate 15 , when the gear 22 engages with the second teeth 20 , the telescopic rod can intermittently swing in the fixed cylinder 12 to prevent grass clippings from adhering to the telescopic plate, thereby facilitating the effective discharge of grass clippings from the fixed cylinder 12 .

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
