Four-leaf grooved pattern trimmer

Abstract

The invention discloses a four-leaf grooved pattern trimmer, and belongs to the technical field of landscaping pruning. The four-leaf grooved pattern trimmer comprises a four-leaf rose curve generation mechanism and a spherical motion tracking mechanism, wherein a path generation motor 8 drives a guide rod lower section 1-2; and under the rotation of the guide rod lower section 1-2, a longitudinal slide block 4 and a transverse slide block 5 as well as a connecting rod 3, a cross guide block 2 has the track of a four-leaf rose line. A spatially three-dimensional four-leaf rose curve type motion is formed under the guide of a grooving motor connecting sleeve 7-10 and a grooving spherical guide shell 7-17; the grooving motor connecting sleeve 7-10 drives a grooving cutter 7-13 to complete trimming of four-leaf grooved rose patterns on the top of a single shrub. According to the four-leaf grooved pattern trimmer, the superficial area of the shrub receiving sunshine is relatively enlarged, a curved surface of the shrub reflecting noise is enlarged, and the reflection direction is changed, so that the vehicle noise is further reduced. Therefore, a driver in a high position feels the motion, and pedestrians can have a sense of spatial heterogeneity.

Description

technical field [0001] The invention relates to the technical field of landscaping pruning, in particular to a four-leaf trough-shaped pattern pruning device. Background technique [0002] Most of the shrubs are planted on the urban road isolation belt, and there are continuous shrubs. Looking along the direction of the road, the inner and outer sides of the continuous shrubs are trimmed into a vertical plane, and the top surface is almost trimmed into a plane, or evenly spaced among the continuous shrubs. Distribute some spherical-shaped shrubs that are higher than the top of continuous shrubs; there are also scattered shrubs, the ground between the shrubs is planted with grass, and the shape of scattered shrubs is mostly spherical, spherical, and paraboloid The shape is similar to the double-leaf hyperboloid shape, and the shapes are different, which not only brings the beauty of green, but also the beauty of the three-dimensional shape. The shrubs on the road isolation be...

Problems solved by technology

[0003] However, although the single-cluster shrubs on the road median have been pruned into approximately spherical, approximately spherical crown, approximately revolving paraboloid and approximately double-leaf hyperboloid shapes, the shape is still not rich enough. In a word, the current single-cluster shrubs The boundary of the shrub is a continuous curved surface, and the surface area of ​​the shrub to receive sunlight is relatively small
