Cutter-head adjusting mechanism and weeding robot

Abstract

The invention relates to a cutter-head adjusting mechanism and a weeding robot. The cutter-head adjusting mechanism includes a cutter-head rack, a connecting rack and an adjusting structure; the adjusting structure is located between the cutter-head rack and the connecting rack and includes a first linear driving part, a second linear driving part and a connecting rod; the two ends of the first linear driving part are respectively and rotatably connected to the cutter-head rack and the connecting rack; the two ends of the connecting rod are respectively and rotatably connected to the cutter-head rack and the connecting rack; and the two ends of the second linear driving part are respectively and rotatably connected to the connecting rod and the connecting rack. Through the arrangement of the adjusting structure connected to the cutter-head rack, the cutter-head adjusting mechanism and the weeding robot are suitable for traditional clean tillage weeding orchards to adjust the depths ofhoeing and the digging dip angles of cutters, and are also suitable for sod-culture orchards to adjust the heights of mowing, so that different weeding demands can be met; and in addition, large operation space can be provided for operators, and convenient checking and replacing of cutter-head can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a cutter head adjustment mechanism and a weeding robot. Background technique [0002] The orchard industry is an important industry in our country. Many weeds will grow among the fruit trees. Weeds will compete with the fruit trees for sunlight and moisture and nutrients in the soil, which will affect the absorption of nutrients by the fruit trees, resulting in slow growth, reduced yield and quality damage of the fruit trees. Therefore, it is necessary to remove weeds in the orchard several times. [0003] Generally, mechanical weeding in orchards is large in size and poor in passability, which damages fruit tree branches and hair roots; it cannot remove weeds between trees, but can only remove weeds between wide rows of fruit trees. The weeding effect is not ideal, and about 30% of the area between fruit trees has weeds It cannot be removed and needs to be manual...

Problems solved by technology

[0003] Generally, mechanical weeding in orchards is large in size and poor in passability, which damages fruit tree branches and hair roots; it cannot remove weeds between trees, but can only remove weeds between wide rows of fruit trees. The weeding effect is not ideal, and about 30% of the area between fruit trees has weeds It cannot be removed, and a second manual removal is required

[0004] However, the weeding height of the existing weeding device is fixed, and the grass roots cannot be eradicated, so that the weeds cannot be completely eradicated; it cannot adapt to the slope or undulation of the grassland
