Description

Technical Field

[0001] The utility model relates to the technical field of garden engineering, in particular to a chassis cleaning device for a lawn mower. Background Art

[0002] When a lawn mower is mowing the lawn, the high-speed rotating blades will not only cut the grass blades that are too high, but also roll up the soil on the surface. The soil containing water and the grass blades are mixed and adsorbed on the chassis of the lawn mower. As the mower works, the soil mixed with grass blades on the chassis will gradually accumulate and be subjected to pressure and friction. It will quickly solidify in the high-speed air flow and the high-temperature environment generated by the high-speed rotation of the mower, forming a dense soil layer firmly attached to the chassis of the mower. The current cleaning method is to turn the mower sideways, then remove the blade and knock off the solidified soil layer by knocking. Since the mower can only lie on its side, the angle between the chassis and the ground is about 120°, and workers can neither shovel it with force nor remove it easily. The soil layer is very hard and difficult to remove, which is laborious and will cause damage to the chassis of the mower.

[0003] Therefore, in view of the above shortcomings, it is necessary to provide a lawn mower chassis cleaning device. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] A lawn mower chassis cleaning device, such as Figure 1 As shown, it includes a support platform 1, an empty box 2, a nozzle 3 and a mud guard 4. The empty box 2 is arranged in the support platform 1, the nozzle 3 is fixedly connected to the top of the empty box 2, and the mud guard 4 is fixedly connected to the top of the nozzle 3.

[0030] Combination Figure 1 , Figure 4The cross-section of the support platform 1 is concave, the empty box 2 is fixedly connected to the concave area of ​​the support platform 1, and the nozzle 3 is also located in the concave area to avoid interference with the trimmer 5. A slope 11 is provided on one side of the support platform 1 in the length direction, and the angle between the slope 11 and the bottom of the support platform 1 is less than 40°. The slope 11 is provided to push the trimmer 5 onto the support platform 1, so that the trimmer 5 with wheels can be placed on the raised parts on both sides of the support platform 1, and there is no need to manually carry and lift the trimmer, which is more time-saving and labor-saving. A car blocking plate 12 is fixedly connected to the top of the other side of the support platform 1 in the length direction. The car blocking plate 12 is L-shaped and extends out of the top of the support platform 1. The car blocking plate 12 is provided to resist the wheels of the trimmer 5 to play a blocking role to prevent the trimmer 5 from being pushed out of the support platform 1 due to excessive force when pushing the cart. A mud guide 13 is provided at the bottom of the concave area of ​​the support platform 1 on the side away from the slope 11. The surface of the mud guide 13 is inclined and the inclination direction is opposite to the inclination direction of the slope 11. The mud guide 13 can allow the washed mud to flow out of the support platform 1 under the flow of water, thereby preventing the mud from sticking to the support platform 1 and the empty box 2.

[0031] Combination Figure 1 , Figure 7 A U-shaped handle 14 is fixedly connected to one side of the support platform 1 close to the slope 11 to lift one side of the support platform 1. The support platform 1 is located below the vehicle blocking plate 12 and is rotatably connected to a platform wheel 15. The support platform 1 is located at the slope 11 and is lifted so that the platform wheel 15 is in contact with the ground. Through the above arrangement, when the cleaning device is not in use, the worker can lift the support platform 1 by hand using the handle 14. At this time, the platform wheel 15 is in contact with the ground, and the worker can take the support platform 1 away from its original place like pulling a suitcase, which is more labor-saving and does not require carrying. In addition, after the support platform 1 is lowered, the platform wheel 15 does not contact the ground to prevent the support platform 1 from moving together with the mower 5 when the mower 5 is pushed. After the mower 5 is moved onto the slope 11, the stability of the support platform 1 can be further improved by stepping on the handle 14, so that the mower 5 can be better pushed onto the support platform 1.

[0032] Combination Figure 1 , Figure 2 , the empty box 2 is a large-diameter hollow columnar structure, and the top of the empty box 2 is a hemispherical structure. The inside and one side of the empty box 2 are connected to the nozzle 3 through a pipe that runs through the support platform 1. The pipe extends out of the support platform 1 and is connected to a joint 21. The joint 21 is rotatably connected with a hexagonal nut to connect with the steam generator and the supercharger. A pipe 22 is fixedly connected to the middle of the top of the empty box 2, and the nozzle 3 is connected to the pipe 22. Setting the empty box 2 as a large-diameter hollow shell can, on the one hand, provide better support for the nozzle 3 to avoid deformation of the connected pipe due to the reaction force of high pressure when the nozzle 3 is working. On the other hand, it can appropriately reduce the weight of the device, which is convenient for workers to lift or move the tricycle, and will not make the support platform 1 too light and have low friction with the ground, making it difficult to push the heavy trimmer 5 onto the support platform 1. The top surface is set as a hemispherical structure to prevent soil accumulation and contamination of the empty box 2.

[0033] Combination Figure 2 , Figure 3 The nozzle 3 includes a main pipe 31, a nozzle 32, a fixed rod 33, an active rod 34, a driving head 35 and a driven rod 36. The main pipe 31 is a pipe that can rotate along the middle. The main pipe 31 is threadedly connected to the pipe 22 so that the nozzle 3 can be replaced according to different equipment such as cleaning trimmers and weeders. The nozzle 32 is fixedly connected to one side of the main pipe 31 and combined with Figure 5 The outlet end of the nozzle 32 points to one side of the weeding chamber 51 of the trimmer 5, the fixed rod 33 is fixedly connected to the other side of the main pipe 31, the active rod 34 is rotatably connected to the main pipe 31 above the nozzle 32, the driving head 35 is fixedly connected to the active rod 34 directly above the nozzle 32, the cross-section of the driving head 35 is a right triangle, the inclined surface of the driving head 35 faces the nozzle 32, and the driven rod 36 is integrally formed with the active rod 34 and is in contact with or separated from the fixed rod 33.

[0034] Combination Figure 2 , Figure 5 The mud guard 4 is a hemispherical structure, and the inner arc surface of the mud guard 4 is fixedly connected to the top of the main pipe 31 to prevent the falling mud from blocking the nozzle 3. A return spring 37 is sleeved on the main pipe 31 between the mud guard 4 and the active rod 34 to move the driving head 35 to the top of the nozzle 32. The two ends of the return spring 37 are respectively fixedly connected to the mud guard 4 and the active rod 34. The mud guard 4 is located just above the nozzle 32 and has a nozzle 41. The nozzle 41 penetrates the mud guard 4 and has an outer diameter greater than the outer diameter of the nozzle 32, ensuring that the steam can be smoothly ejected to the trimmer 5.

[0035] Combination Figure 2 , Figure 6The steam generator connected to the joint 21 has a power of 12KW and can generate steam at 0.7MPa and a temperature of 150-170°C. It is small in size and can be transported with the support platform 1 by a tricycle. The steam generated by the steam generator is then pressurized to more than 2MPa by the supercharger, and the steam is sprayed into the weeding chamber 51 of the trimmer 5 through the main pipe 31 and the nozzle 32. At this time, the pressure of the steam pushes the driving head 35 away, and the driven rod 36 rotates a certain angle under the drive of the active rod 34 to separate from the fixed rod 33, and then loses the effect of the steam, and the reset spring 37 drives the active rod 34 to reset. At this time, the driven rod 36 knocks the fixed rod 33 to rotate the upper part of the main pipe 31, so that the nozzle 32 and the like rotate at a certain angle at the same time. At this time, the driving head 35 is reset and is pushed by the steam to drive the active rod 34 to rotate, and the nozzle 32 is repeatedly rotated in an intermittent circle, and the rotation direction is the same as the rotation direction of the blade of the trimmer 5. High-temperature and high-pressure steam is sprayed to the bottom of the trimmer 5. The solidified soil layer begins to absorb water vapor from the surface and softens in the high-temperature steam environment. At the same time, the high-pressure spray peels off the softened soil layer on the surface. The chassis of the trimmer 5 is cleaned by gradual softening and peeling, without the need for manual shoveling. The steam can also take the soil away from the support platform 1 after liquefaction and fall, and also has a certain self-cleaning function.
