Description

Technical Field

[0001] This invention relates to the field of garden machinery technology, specifically a lawn mower. Background Technology

[0002] Lawn mowers belong to the field of garden machinery and are mainly used for trimming and maintaining lawns. Existing lawn mowers usually use an internal combustion engine to drive the blade shaft to rotate, which drives the mowing blades to cut the lawn, and the grass clippings are discharged or collected by wind or mechanical transmission. However, traditional lawn mowers have some technical defects in use and cannot fully meet the requirements of efficient, clean and safe operation.

[0003] Existing lawn mowers have several technical problems during use. The grass clippings are of varying lengths and easily get tangled in the impeller, guide channels, or conveying pipes, causing blockages, reducing conveying efficiency, and affecting the continuity of operations. Grass clippings and dust are easily dispersed during discharge or collection, causing environmental pollution and increasing the risk of dust inhalation for operators. The collection device has a complex structure, is inconvenient to disassemble and clean, and is difficult to maintain, increasing labor intensity and equipment operating costs. In addition, existing lawn mowers lack effective measures for uniform flow, graded filtration, and humidification of grass clippings, which limits mowing efficiency and dust control levels.

[0022] Please see Figures 1-10 The present invention provides a technical solution: a lawn mower, including a mower frame 1, an internal combustion engine 101 on the mower frame 1, a cutter shaft 102 installed at the output end of the internal combustion engine 101, an outer protective shell 103 on the mower frame 1, and a cutting component 3 installed on the outer surface of the cutter shaft 102. The lawnmower frame 1 is equipped with a guide assembly 2, which includes a guide shell 201 and a backward-curved centrifugal impeller 202. The guide shell 201 is installed on the inner surface of the outer protective shell 103, the backward-curved centrifugal impeller 202 is installed on the outer surface of the blade shaft 102, the inner protective shell 203 is installed on the inner surface of the guide shell 201, and a number of ventilation holes 204 are evenly distributed on the outer surface of the inner protective shell 203. A mesh 205 is installed on the inner surface of each ventilation hole 204, a mesh 206 is installed on the bottom surface of the inner protective shell 203, and an air inlet 207 is opened on the bottom surface of the guide shell 201. A collection and processing component 4 is installed on the outer surface of the guide shell 201. The guide component 2 is used to guide the grass fibers cut by the cutting component 3 into the guide shell 201. Under the action of the backward-curved centrifugal impeller 202, an airflow is formed, which blows the grass fibers along the guide shell 201 into the collection and processing component 4. Through the design of the cutting component 3, the guide component 2 and the airflow collection and processing component 4, the grass clippings are efficiently transferred and the blockage is reduced, thereby improving the continuous operation capability and collection efficiency of the whole machine.

[0023] The cutting assembly 3 includes a sleeve 303 and several connecting brackets 304. A sleeve is installed on the outer surface of the cutter shaft 102. Connecting brackets 304 are evenly distributed on the outer surface of the sleeve 303. A lever 305 is installed on one end of each connecting bracket 304. A lever 306 is installed on one end of each lever 305. A crushing blade 307 is installed on the outer surface of each lever 306. This secondary crushing process makes the grass clippings easier to transport and reduces the risk of entanglement.

[0024] The outer surface of lever 1 305 is in active contact with the outer surface of the inner protective sleeve 203, and the outer surface of lever 2 306 is in active contact with the outer surface of mesh 3 206. Through contact guidance and scraping action, the adhesion and accumulation of grass fibers are reduced, the smoothness of guidance is improved and the probability of blockage is reduced.

[0025] A clamping block 301 is installed on the outer surface of the blade shaft 102, and a grass-cutting blade 302 is installed on the inner surface of the clamping block 301. This is used to achieve stable fixation of the grass-cutting blade 302 and high-speed rotation cutting, ensuring uniform and reliable grass-cutting effect.

[0026] The collection and processing component 4 includes a liquid storage box 401 and a slot 402. The liquid storage box 401 is installed on the outer surface of the guide shell 201. The slot 402 is opened on the outer surface of the liquid storage box 401. The collection box 403 is movably installed on the outer surface of the liquid storage box 401. The collection box 403 is provided with an insertion block 404. The outer surface of the insertion block 404 is in active contact with the inner wall of the slot 402, so as to realize the quick disassembly and assembly of the collection box 403, improve the cleaning efficiency and facilitate maintenance.

[0027] The liquid storage box 401 is equipped with a partition net 406 inside, and a miniature water pump 405 is installed on the outer surface of the liquid storage box 401. A water suction pipe 407 is installed at the output end of the miniature water pump 405, and a water outlet pipe 408 is installed at the other output end of the miniature water pump 405, so as to realize the circulation and transportation of the humidified liquid, prevent grass clippings from entering the liquid storage area, and ensure the stability of the spraying.

[0028] One end of the water outlet pipe 408 extends into the interior of the liquid storage box 401. The interior of the liquid storage box 401 is evenly provided with drip grooves 409. Sponge balls 410 are movably installed on the inner walls of several drip grooves 409 to achieve uniform liquid release and slow-release humidification, improve dust suppression effect and avoid local water accumulation.

[0029] The collection box 403 has several ventilation holes 411 evenly distributed inside. Each ventilation hole 411 has a mesh 412 installed on its inner wall. The collection and processing component 4 is used to humidify the grass clippings and dust entering the collection box 403 to reduce dust diffusion. This is used to suppress dust while ensuring airflow discharge, improve the working environment and reduce secondary dust.

[0030] The inner protective sleeve 203 is used to cover the backward-curved centrifugal impeller disk 202 to reduce the entry of grass clippings into the impeller disk and improve the operating stability of the backward-curved centrifugal impeller disk 202, and avoid the efficiency reduction or failure caused by grass clippings.

[0031] The collection box 403 can be quickly disassembled and assembled via slot 402 and insert 404, which facilitates quick cleaning and maintenance and improves usage efficiency.

[0032] The specific workflow of this invention is as follows: The lawnmower frame 1 provides support and a mounting foundation for the entire machine. An internal combustion engine 101 is mounted on it, serving as a power source to power the blade shaft 102, the subsequent guide assembly 2, and the cutting assembly 3. The output end of the internal combustion engine 101 is connected to the blade shaft 102, enabling the blade shaft 102 to rotate and drive the cutting assembly 3. An outer protective sleeve 103 covers the frame and blade shaft 102, providing protection and preventing operators from contacting the rotating parts. It also guides airflow and grass clippings towards the guide assembly 2. The cutting assembly 3 is mounted on the outside of the blade shaft 102. A clamping block 301 is used to fix the lawnmower blade 302 and ensure stable blade rotation. The blade shaft 102 drives the clamping block 301 and the lawnmower blade 302 to rotate. The lawnmower blade 302 directly performs the mowing operation, cutting the lawn. 102 drives the sleeve 303, connecting bracket 304, lever 1 305, lever 2 306, and crusher 307 to rotate. The sleeve 303 and connecting bracket 304 support and fix lever 1 305, lever 2 306, and crusher 307, ensuring that lever 1 305, lever 2 306, and crusher 307 rotate in tandem with the cutter shaft 102. Lever 1 305 and lever 2 306 contact the inner protective sleeve 203 and the partition net 3 206 to prevent grass fibers from sticking to the outside of the inner protective sleeve 203 and the partition net 3 206, guiding the grass fibers into the guide assembly 2. At the same time, the crusher 307 performs secondary crushing of grass clippings, preventing grass clippings from being too long or tangled. The crusher 307 is used to cut longer grass clippings, crushing them into a length suitable for suction into the guide assembly 2, improving conveying efficiency and preventing blockage.

[0033] The guide assembly 2 is located between the cutting assembly 3 and the collection and processing assembly 4. It guides the cut grass fibers into the guide shell 201 and transports them to the collection and processing assembly 4 via airflow. The guide shell 201 provides a closed channel so that the grass fibers can be smoothly transported by the airflow. The backward-curved centrifugal impeller 202 rotates to generate negative pressure airflow, which accelerates the grass fibers along the guide shell 201 to the collection and processing assembly 4. The inner protective sleeve 203 covers the backward-curved centrifugal impeller 202 to prevent grass clippings from tangling with it. The partitions 205 and 206 of the ventilation hole 204 perform flow equalization and graded filtration of the incoming airflow, keeping the grass clippings stable during the transport process and reducing the risk of turbulence and tangling. The air inlet chamber 207 is located at the bottom of the guide shell 201 to ensure that the cut grass fibers can smoothly enter the guide assembly 2.

[0034] The collection and processing component 4 is installed on the outside of the guide component 2. The liquid storage box 401 is used to store the humidifying liquid. The micro water pump 405 delivers the liquid to the dripping tank 409 through the suction pipe 407 and the outlet pipe 408. The dripping tank 409 and the sponge ball 410 are used to release the liquid evenly, humidifying the grass clippings and dust entering the collection box 403, causing them to settle and reducing dust diffusion. The collection box 403, the slot 402 and the plug 404 form a detachable structure, which is convenient for cleaning and maintaining grass clippings. The partition net 406 prevents grass clippings from entering the liquid storage tank. The partition net 412 of the ventilation hole 411 facilitates airflow and prevents grass clippings from being blown out, so that the grass clippings settle evenly and prevent blockage.
