Description

Technical Field

[0001] This invention relates to the field of agricultural machinery cleaning equipment technology, specifically to a cutter cleaning device that works in conjunction with a suspended lawnmower. Background Technology

[0002] During operation, the cutter head and blades of overhead lawnmowers easily accumulate grass clippings, dirt, and other debris. If not cleaned promptly, this not only affects cutting efficiency but also accelerates blade wear. Current technology relies heavily on manual cleaning with handheld high-pressure water guns, which suffers from low cleaning efficiency, high labor intensity, and difficulty in cleaning hard-to-reach areas such as the blade gaps. Some automated cleaning equipment often only rinses one side of the blade, resulting in limited cleaning effectiveness.

[0003] In particular, the cutter assembly with symmetrically protruding arc-shaped cutter discs lacks effective coordination with the mower structure, resulting in cutter table shaking or inaccurate positioning during cleaning, inadequate cleaning of the internal gaps of the arc-shaped cutter disc, and the cutter assembly's typically low working height and inability to be easily lifted due to its connection with the tractor's suspension platform, making bottom cleaning difficult. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a mower cleaning device that works with a suspended lawnmower, which aims to solve the problems of manual labor, low efficiency and blind spots in the cleaning of mowers in the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is: a mower cleaning device for use with a suspended lawnmower, comprising:

[0006] A cleaning station assembly includes a cleaning base and a support base extending to the left and right sides of the cleaning base. The support base is equipped with a hydraulic lifting device. A power function device mounting box is located in the center of the cleaning base. Two cleaning stations are symmetrically arranged on the left and right sides of the power function device mounting box.

[0007] A lawnmower assembly, comprising a suspension frame, a cutter assembly, and a floating guide structure connected between the suspension frame and the cutter assembly, the floating guide structure allowing the cutter assembly to rise and fall independently relative to the suspension frame when lifted by the hydraulic lifting device;

[0008] The cleaning station includes a cleaning cover that is slidably mounted on the cleaning base. The cleaning cover has an opening on its outer side. When the cleaning cover moves toward the cutting table assembly that has arrived at the station, the cutting table assembly enters the cleaning cover from the opening.

[0009] The cleaning hood is equipped with several sets of longitudinal nozzle assemblies that cooperate with the symmetrically protruding cutter discs in the cutting table assembly. Each longitudinal nozzle assembly consists of two parts symmetrically arranged at the upper and lower ends inside the cleaning hood. Each part includes an arc-shaped nozzle assembly that is slidably disposed on the inner wall of the cleaning hood and is arranged in a manner that matches the shape of the cutter disc. The cleaning hood is also equipped with several sets of transverse nozzle assemblies that cooperate with the guide boss at the front end of the cutting table assembly.

[0010] The longitudinal nozzle assembly is responsible for cleaning the top blade surface and top gap of the cutter disc, while the transverse nozzle assembly, in cooperation with the guide boss, is responsible for cleaning the bottom blade surface and bottom gap of the cutter disc. Both the longitudinal nozzle assembly and the transverse nozzle assembly are connected to the power function device mounting box through built-in pipelines.

[0011] Furthermore, the front guide boss of the present invention has a triangular cross-section and an arc-shaped end. The transverse nozzle assembly includes two parallel transverse nozzles arranged vertically. An elastic tube is provided between the transverse nozzle and the corresponding built-in pipeline on the inner wall of the cleaning hood. When the two transverse nozzles move forward with the cleaning hood toward the cutting table assembly, they contact the guide boss. Under the combined action of the arc end of the guide boss and the deformation of the elastic tube, the spray direction changes along the upper and lower sides of the guide boss, so that the spray direction is aligned with the inner bottom of the corresponding cutter head.

[0012] Furthermore, the guide boss of the present invention is provided with guide channel tubes at both the upper and lower ends for the insertion of corresponding transverse nozzles, and the guide channel tubes have an open structure on the front and upper sides near the cutter head.

[0013] Furthermore, the power function device mounting box of the present invention is equipped with an electric push rod device for moving the cleaning hood and a water pump. The input end of the water pump is connected to the water tank above the power function device mounting box, and the output end of the water pump is connected to the built-in pipeline.

[0014] Furthermore, the floating guide structure of the present invention includes an L-shaped connector, the bottom of which is rotatably connected to the rotating shaft at the end of the suspension frame, and the top of which is connected to the hydraulic balance rod on the suspension frame through a movable pin cavity. The L-shaped connector is provided with a slot with an opening at the top, and a sliding connecting block on one side of the cutting table assembly is slidably inserted into the slot and locked on the top side by a limiting bolt.

[0015] Furthermore, the movable pin cavity of the present invention is movably inserted into the pin hole at the end of the hydraulic balance rod via a pin, and the connecting end of the hydraulic balance rod has rotation space within the movable pin cavity. Meanwhile, the bottom of the power mounting end on the other side of the hydraulic balance rod is a movable elastic mounting structure.

[0016] Furthermore, the cutting platform assembly of the present invention has recessed positioning parts on the lower sides of its left and right ends that cooperate with the hydraulic lifting device.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention achieves thorough cleaning of the bottom of the cutter head, eliminating blind spots. In existing technologies, the cutter head assembly of lawnmowers is typically rigidly connected or can only rise and fall as a whole with the suspension frame, making it difficult for high-pressure water jets to effectively reach the gap between the bottom of the cutter head and the inner side of the blade. This invention, by incorporating a floating guide structure within the lawnmower assembly, allows the cutter head assembly to rise independently relative to the suspension frame when lifted by a hydraulic lifting device, thereby completely exposing the top, bottom, and inner / outer gaps of the blade to the cleaning station. Combined with the three-dimensional spraying of the longitudinal and transverse nozzle assemblies, this achieves all-around, blind-spot-free cleaning of the cutter head assembly and blade, significantly improving cleaning quality.

[0019] 2. The dual-station parallel design significantly improves cleaning efficiency. The cleaning station component of this invention features two independent cleaning stations symmetrically arranged on the left and right sides of the power unit mounting box. In actual operation, two suspended lawnmowers can drive into their respective support bases from either side. Once in position, the hydraulic lifting device lifts the cutting table, allowing them to execute the cleaning process in parallel. This effectively reduces equipment downtime and improves overall operational efficiency.

[0020] 3. The transverse nozzle assembly engages with a guide boss at the front end of the cutter head assembly. The guide boss has a triangular cross-section with rounded ends. Combined with the elastic tube at the transverse nozzle connection, this allows the upper and lower transverse nozzles to automatically change their spray direction and precisely align with the inner bottom of the cutter head as they follow the cleaning hood, utilizing the physical contour of the guide boss and the elastic deformation of the elastic tube. This purely mechanical adaptive structure requires no additional sensors or electronic control components, offering high reliability and low cost.

[0021] 4. In this invention, the arc-shaped contour structure of the longitudinal nozzle assembly can closely fit the outer edge contour of the cutter disc. The upper and lower sets of arc-shaped nozzles respectively spray the top blade surface, top gap and blade root of the cutter disc from the top and bottom, respectively, to achieve full coverage, equidistant and multi-angle three-dimensional spraying. This significantly improves the coverage area and impact force of a single cleaning, solves the problem of spray blind spots in traditional linear nozzles, and ensures the thorough removal of stubborn grass stains and dirt from the top of the cutter disc.

[0022] 5. High degree of modularity, facilitating upgrades and modifications to existing lawnmowers. The cleaning station component of this invention is an independent module that can be flexibly arranged on the ground of a parking apron or garage. The improvements to the lawnmower component are mainly focused on the floating guide structure at the connection between the suspension frame and the cutter head. The scope of modification is small, and it has good compatibility with the suspension interface of existing suspended lawnmowers, facilitating low-cost upgrades to existing equipment and possessing good market promotion value.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 6 As shown, this embodiment provides a mower cleaning device for use with a suspended lawnmower, including a cleaning station assembly and a lawnmower assembly.

[0033] The cleaning station assembly includes a cleaning base 1, with supporting bases 2 extending to the left and right sides of the cleaning base 1. Hydraulic lifting devices 3 are mounted on the supporting bases 2. A power function device mounting box 4 is located in the center of the cleaning base 1, and two cleaning stations are symmetrically arranged on the left and right sides of the power function device mounting box 4. The power function device mounting box 4 contains an electric actuator 15, a water pump 16, and a water tank 17 above it.

[0034] Each cleaning station is equipped with a cleaning hood 7 that is slidably mounted on a cleaning base 1, and the cleaning hood 7 has an opening on its outer side. Inside the cleaning hood 7 are a longitudinal nozzle assembly and a transverse nozzle assembly. The longitudinal nozzle assembly includes two sets of arc-shaped nozzle groups 9 arranged symmetrically vertically, each set consisting of multiple nozzles slidably mounted on the inner wall of the cleaning hood 7 arranged in an arc shape that matches the shape of the cutter head 8. The transverse nozzle assembly includes two parallel transverse nozzles 12, with a spring tube 13 connecting the transverse nozzles 12 to the internal piping 11.

[0035] The lawnmower assembly includes a suspension frame 5, a cutter assembly 6, and a floating guide structure connecting the two. The floating guide structure includes an L-shaped connector 18, the bottom of which is rotatably connected to a pivot at the end of the suspension frame 5, and the top of which is connected to a hydraulic balance rod 20 via a movable pin cavity 19. The movable pin cavity 19 is movably inserted into a pin hole at the end of the hydraulic balance rod 20 via a pin 24, and the connecting end of the hydraulic balance rod 20 has rotational space within the movable pin cavity 19. The bottom of the power mounting end on the other side of the hydraulic balance rod 20 is a movable elastic mounting structure 25. The L-shaped connector 18 has a slot 21 with an open top, and a sliding connecting block 22 on one side of the cutter assembly 6 is slidably inserted into the slot 21 and locked by a limiting bolt 23.

[0036] The front end of the cutting table assembly 6 is provided with a guide boss 10, which has a triangular cross-section and rounded ends. Both the upper and lower ends of the guide boss 10 are provided with guide channel tubes 14 for the insertion of corresponding transverse nozzles 12. The guide channel tubes 14 have openings on the front and upper sides near the cutter head 8. The lower sides of both the left and right ends of the cutting table assembly 6 are provided with recessed positioning parts 26 that cooperate with the hydraulic lifting device 3.

[0037] Workflow:

[0038] Before cleaning, loosen the limiting bolt 23 to allow the cutter assembly 6 to float. Drive the lawnmower into the cleaning station, positioning the cutter assembly 6 above the cleaning base 1, with the recessed positioning piece 26 aligned with the hydraulic lifting device 3. Activate the hydraulic lifting device 3 to lift the cutter assembly 6 upwards. The cutter assembly 6 rises independently relative to the suspension frame 5 via the sliding connecting block 22 along the slot 21. Subsequently, the electric push rod device 15 pushes the cleaning hood 7 towards the cutter assembly 6, allowing the cutter assembly 6 to enter the cleaning hood 7 through the opening. At this time, the upper and lower sets of arc-shaped nozzles 9 perform high-pressure cleaning on the top blade surface and top gap of the cutter head 8. Simultaneously, the two transverse nozzles 12 contact the guide boss 10 during their forward movement. Under the combined action of the compression of the guide boss 10 and the elastic deformation of the elastic tube 13, they change their spray direction along the upper and lower sides of the guide boss 10 and stably insert into the guide channel tube 14, precisely targeting the inner bottom of the cutter head 8 for cleaning. After cleaning, the electric actuator 15 drives the cleaning hood 7 to retract and reset, the hydraulic lifting device 3 descends, the cutting table assembly 6 automatically falls back under gravity, and finally the limit bolt 23 is tightened.
