[0032] The high-speed slope lawn trimming and crushing integrated device and the use method thereof provided in the embodiment of the present invention are now described.

[0033] Reference Figure 1-9 A high-speed slope lawn trimming and crushing integrated equipment comprises a cart 1, a rotating platform 2 and a support structure, and a crushing and trimming mechanism 6 is fixedly connected to the end of the support structure. The cart 1 carries the equipment along the highway, and the support structure adjusts the position of the crushing and trimming mechanism 6 to trim and crush the slope lawn outside the guardrail.

[0034] The crushing and trimming mechanism 6 includes a fixing assembly, an air motor 65, a rotating shaft 66, a cutting blade 611, a planetary reduction gear mechanism, a crushing assembly and a safety mechanism.

[0035] Specifically, the fixed assembly is fixedly connected to the bracket structure, the pneumatic motor 65 is fixedly connected to the fixed assembly, the rotating shaft 66 is movably connected to the fixed assembly through a bearing, and the output end of the pneumatic motor 65 is transmission-connected to the rotating shaft 66, the cutting knife 611 is movably connected to the rotating shaft 66, the crushing assembly is fixedly connected to the rotating shaft 66, and a planetary reduction gear mechanism is arranged between the cutting knife 611 and the rotating shaft 66, and a safety mechanism is arranged at the bottom end of the rotating shaft 66.

[0036] The fixed component is the main part, and the pneumatic motor 65 drives the rotating shaft 66 to rotate, directly driving the crushing component to rotate at high speed, and drives the cutting knife 611 through the planetary reduction gear mechanism. The cart 1 carries the equipment forward, and the rotating cutting knife 611 continuously moves toward the uncut lawn part. The broken leaves after cutting enter the gap of the cutting knife 611, are crushed by the high-speed rotating crushing component, and then thrown out, thereby realizing efficient trimming and crushing of high-speed slope lawns.

[0037] The safety mechanism is used to limit the lowest position of the crushing and trimming mechanism 6 to prevent the high-speed rotating cutting knife 611 from hitting the ground due to the crushing and trimming mechanism 6 being too low to the ground, thereby protecting the device.

[0038] The cutting knife 611 includes a small cutting wheel 6111 and a large cutting wheel 6112 . The small cutting wheel 6111 and the large cutting wheel 6112 are arranged in parallel and spaced apart from each other, and the small cutting wheel 6111 and the large cutting wheel 6112 are fixedly connected via a plurality of connecting columns 6113 .

[0039] The small cutting wheel 6111 and the large cutting wheel 6112 rotate synchronously, and there is a gap between the small cutting wheel 6111 and the large cutting wheel 6112. When the device is working, it moves forward continuously, and the cut grass leaves will enter the gap.

[0040] The crushing assembly includes a lower crushing wheel 612 and an upper crushing wheel 613 . The lower crushing wheel 612 is located between the small cutting wheel 6111 and the large cutting wheel 6112 , and the upper crushing wheel 613 is located above the large cutting wheel 6112 .

[0041] The lower crushing wheel 612 and the upper crushing wheel 613 rotate at high speed along with the rotating shaft 66, wherein the lower crushing wheel 612 is used to crush the grass leaves that enter the gap between the small cutting wheel 6111 and the large cutting wheel 6112, and the upper crushing wheel 613 is used to crush the relatively high grass leaves, which are higher than the large cutting wheel 6112. After being cut off, they will fall downward. Since the device is moving forward, they will fall on the upper section of the large cutting wheel 6112, and then be rolled inward and crushed by the upper crushing wheel 613.

[0042] Reference Figure 1In this embodiment, the support structure includes a boom 3 and a telescopic arm 5, the bottom end of the boom 3 is hinged to the movable plate of the rotating table 2, and a first telescopic member 4 for adjusting the angle of the boom 3 is arranged between the boom 3 and the movable plate of the rotating table 2, the top end of the boom 3 is hinged to the top end of the telescopic arm 5, and a second telescopic member 7 for adjusting the angle of the telescopic arm 5 is arranged on the sides of the boom 3 and the telescopic arm 5.

[0043] The rotating table 2 can drive the upper support structure and the crushing and mowing mechanism 6 to rotate, so as to facilitate mowing the lawn on both sides of the driveway. The movement of the first telescopic member 4 is used to adjust the angle of the upper arm 3, which can change the horizontal extension length of the upper arm 3 (the length of the upper arm 3 is fixed, and the more it leans to the vertical, the shorter the extended part); the movement of the second telescopic member 7 is used to adjust the angle between the arm 3 and the telescopic arm 5. One of its purposes is to adjust the position of the crushing and mowing mechanism 6 (so that its bottom surface is basically parallel to the bottom surface of the slope), and the second purpose is to work together with the first telescopic member 4 to adjust the position of the crushing and mowing mechanism 6; the movement of the telescopic arm 5 is used to adjust the height of the crushing and mowing mechanism 6 from the ground. Generally, the safety mechanism is just in contact with the ground to ensure that the height of the mowed lawn is appropriate.

[0044] Reference Figure 2 In this embodiment, the telescopic arm 5 includes a small arm 51, a first connecting plate 52 is slidably connected to the side of the small arm 51, a third telescopic member 53 is fixedly connected to the side of the small arm 51, and a telescopic end of the third telescopic member 53 is fixedly connected to the first connecting plate 52.

[0045] The third telescopic member 53 moves, driving the first connecting plate 52 and the small arm 51 to slide, so that the overall length of the telescopic arm 5 changes.

[0046] Reference Figure 3-9 In this embodiment, the fixing assembly includes an upper fixing plate 61 and a lower fixing plate 63, the upper fixing plate 61 and the lower fixing plate 63 are spaced apart, and the upper fixing plate 61 and the lower fixing plate 63 are fixedly connected by a plurality of columns, the pneumatic motor 65 is fixedly connected to the upper fixing plate 61, the rotating shaft 66 is connected to the lower fixing plate 63 by a bearing, and a second connecting plate 62 is fixedly connected to the top of the upper fixing plate 61.

[0047] The structural design of the upper fixing plate 61 and the lower fixing plate 63 makes the installation positions of the second connecting plate 62, the rotating shaft 66, and the pneumatic motor 65 more reasonable, without interference between them, and with a stronger integrity.

[0048] Reference Figure 5-7 In this embodiment, the safety mechanism includes a cavity 67 opened at the bottom end of the rotating shaft 66, a piston member 69 is arranged inside the cavity 67, a protective rod 68 is fixedly connected to the bottom of the piston member 69, the bottom end of the protective rod 68 extends out of the cavity 67, and a limiting cover 610 is detachably connected to the bottom end of the rotating shaft 66.

[0049] When the bottom of the protection rod 68 touches the ground, it will not move downward any further and will transfer force to the piston 69. If the crushing and trimming mechanism 6 continues to move downward as a whole, it will compress the area inside the cavity 67 and above the piston 69, generating a high pressure state inside. The reaction force will push the piston 69. When the internal air pressure is high, it can limit the downward movement of the crushing and trimming mechanism 6 and prevent the crushing and trimming mechanism 6 from colliding with the ground.

[0050] Reference Figure 5-9 In this embodiment, the planetary reduction gear mechanism includes a gear ring 614, a driving gear 615 and a planetary gear 619. The gear ring 614 is fixedly connected to the inner ring of the large cutting wheel 6112, the driving gear 615 is fixedly connected to the rotating shaft 66, the planetary gear 619 is located between the gear ring 614 and the driving gear 615, and is meshed with the gear ring 614 and the driving gear 615. An upper limiting plate 617 and a lower limiting plate 616 are respectively provided above and below the planetary gear 619. Both ends of the central axis of the planetary gear 619 are respectively fixedly connected to the upper limiting plate 617 and the lower limiting plate 616. A connecting rod 618 is fixedly connected to the top of the upper limiting plate 617, and the connecting rod 618 is fixedly connected to the fixing assembly.

[0051] The connecting rod 618, the upper limiting plate 617, the lower limiting plate 616 and the central axis of the planetary gear 619 are equivalent to the planetary carrier of the planetary gear 619, which is fixedly connected to the fixed component. The driving gear 615 is the input gear, and the gear ring 614 is the output gear, which together constitute a planetary reducer. The starting motor directly drives the driving gear 615 to rotate at high speed. After deceleration, it drives the gear ring 614 and the large cutting wheel 6112 to rotate.

[0052] The upper crushing wheel 613 and the lower crushing wheel 612 are both provided with flanges, which are fixedly connected to the end of the driving gear 615 through a bolt group, and the driving gear 615 and the rotating shaft 66 are an integrated structure.

[0053] Reference Figure 3 In this embodiment, the device also includes a protective cover 64, which half covers the outer side of the cutting knife 611. The protective cover 64 is fixedly connected to the fixing assembly to protect the cutting knife 611 and avoid collision with the ground.

[0054] A magnetic block is provided at the bottom of the protective cover 64 to remove broken iron pieces in the lawn and avoid collision with the cutting blade 611.

[0055] The large cutting wheel 6112 is located above the small cutting wheel 6111, the diameters of the lower crushing wheel 612 and the upper crushing wheel 613 are both 1 / 2 of the small cutting wheel 6111, the lower crushing wheel 612 is located between the large cutting wheel 6112 and the small cutting wheel 6111, and there is a crushing space on the outside of the lower crushing wheel 612, and there is a crushing space above the large cutting wheel 6112 and on the outside of the upper crushing wheel 613.

[0056] A method for using a high-speed slope lawn trimming and crushing integrated device, the steps are: using a rotating table 2 and a support structure to control the position of a crushing and trimming mechanism 6, an air motor 65 drives a rotating shaft 66, a cutting knife 611 and a crushing assembly to rotate, and a cart 1 travels along the inner side of the highway to trim and crush the slope lawn outside the highway guardrail.

[0057] The cart 1 moves along the inner side of the highway, driving the entire equipment to move along the slope, achieving efficient and rapid lawn trimming and crushing, saving time and effort, and 2-3 workers can operate, achieving an average cleaning of 8-20 kilometers per hour.
