specific Embodiment 1

[0069] This embodiment is an embodiment of a weeder.

[0070] The weeder of the present embodiment, such as figure 1 , figure 2 and image 3 As shown, it includes base 1, scale telescopic sleeve 2, scale 3, handle 4, adjustment rod 5, horizontal device 6, bracket 7, bottom plate 8, generator 9, motor 10 and blade 11; bracket 7, generator 9 and scale The telescopic sleeve 2 is fixedly installed above the base 1; the horizontal device 6 includes two connecting rods 6-1, and the two connecting rods 6-1 are respectively fixed on both sides of the adjusting rod 5, each of the connecting rods 6 The ends of -1 are respectively fixed with horizontal driving rollers 6-2, which rotate synchronously with the adjustment rod 5; the horizontal driving rollers 6-2 are wound with pulling ropes 6-3, The pulling rope 6-3 is also fixedly connected with the base plate 8, the base plate 8 is provided with a motor 10 powered by the generator 9, the rotating shaft of the motor 10 passes through ...

specific Embodiment 2

[0083] This embodiment is an embodiment of a weeder.

[0084] The above-mentioned weeding machine, on the basis of the specific embodiment 1, is further limited under the condition of Δα≈0, and is required to satisfy the following two conditions at the same time:

[0085] Condition one:

[0086]

[0087] Condition two:

[0088] R 4 =L 2 L 3 sinα

[0089] Wherein, Δα is the clockwise rotation angle of the horizontal driving roller 6-2.

[0090] Under the condition that the angle Δα of the horizontal driving roller 6-2 rotates clockwise is Δα≈0, then pass L 2 , L 3 , L 4 Under the special parameter relationship of , r and α, it can also ensure that the blade is always parallel to the ground, and the grass is cut more smoothly.

specific Embodiment 3

[0091] This embodiment is an embodiment of a weeder.

[0092] The above-mentioned weeding machine, on the basis of specific embodiment 1 or specific embodiment 2, further defines that said scale 3 is provided with several groups of connected T-shaped holes 3-1, and said several T-shaped holes 3-1 Size numbers are set on the sides.

Abstract

The invention relates to the technical field of engineering machinery, in particular to a method for determining parameters of a weeding machine, which solves the problems that the special structure of the existing weeding machine can only be transversely trimmed along a slope and cannot be trimmed along the slope during grass trimming, and the cutting is not orderly enough. The weeding machine comprises a base; a bracket, a generator and a scale telescopic sleeve are fixedly arranged above the base; a horizontal device comprises two connecting rods, the two connecting rods are respectively fixed on two sides of an adjusting rod, the end parts of each connecting rod are respectively fixed with a horizontal driving roller, and the horizontal driving roller and the adjusting rod rotate synchronously; a traction rope is wound on the horizontal driving roller, a motor powered by the generator is arranged on a bottom plate, and a rotating shaft of the motor penetrates through the bottom plate and is provided with a blade; one end of the upper surface of the base is provided with a fixed scale telescopic sleeve, the scale telescopic sleeve is provided with a scale, and the top end of theadjusting rod passes through the scale telescopic sleeve through a clamping device to be connected with a handle, so that the purpose that the weeding machine can be smoothly trimmed along the slopeduring grass trimming is achieved.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to a method for determining parameters of a weeding machine. Background technique [0002] Lawn mower (Lawn mower), also known as weeder, lawnmower, lawn trimmer, etc., a lawn mower is a mechanical tool used to trim lawns, vegetation, etc. Mechanism, blades, handrails, and control parts. The cutter head is mounted on the walking wheel. The cutter head is equipped with an engine. The output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, saving the work of weeding workers. Time, reducing a lot of human resources. [0003] Due to the special structure of the weeding machine, the grass can only be trimmed horizontally along the slope, and cannot be trimmed up and down the slope, and the cutting is not neat enough. Contents of the invention [0004] In view of the above problems, the obj...
