A robot for weeding and obstacle avoidance

Abstract

The invention relates to a robot for weeding and obstacle avoidance, comprising a weeding and obstacle avoidance mechanism, a cutterhead adjustment mechanism and a mobile platform; the first end of the cutterhead adjustment mechanism is connected with the weeding and obstacle avoidance mechanism, and the second end of the cutterhead adjustment mechanism is connected The platform is connected; the cutterhead adjustment mechanism adjusts the height and / or inclination angle of the cutterhead. The invention uses the weeding and obstacle avoidance mechanism to realize automatic weeding and effective obstacle avoidance at the same time, avoiding damage to fruit trees; adopts the cutter head adjustment mechanism, which is suitable for traditional clearing and weeding orchards, and can adjust the depth of hoeing and the inclination of the cutter into the soil; Grass-made orchards can adjust the height of mowing to meet different weeding needs; and adapt to weeding on slopes, using the adjustment structure to adjust the inclination angle of the cutterhead to the same as the slope, so as to remove all weeds on the slope; in addition, provide operators with Larger operating space is convenient for inspection and replacement of cutter head.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a robot for weeding and obstacle avoidance. Background technique [0002] The orchard industry is an important industry in my country, and the fruit trees in the orchard are planted according to a certain row spacing and plant spacing. Because the distance between the fruit trees is relatively large, many weeds will grow between the fruit trees, and the weeds will absorb the nutrients in the soil, affecting the growth and yield of the fruit trees. Therefore, it is necessary to remove the weeds in the orchard many times. [0003] With the continuous improvement of the mechanization level of orchards, various types of weeding machines have emerged at home and abroad, but the level of intelligence of orchard weeding machines is low, the number of dedicated advanced weeding machines is small, the content of weeding technology is low, the operating area is small, and th...

AI Technical Summary

Problems solved by technology

[0003] With the continuous improvement of the mechanization level of orchards, various types of weeding machines have emerged at home and abroad, but the level of intelligence of orchard weeding machines is low, the number of dedicated advanced weeding machines is small, the content of weeding technology is low, the operating area is small, and the price is expensive.

Most orchard weeders work in the way of walking between rows, which makes it impossible to effectively remove the weeds between the fruit trees, especially the weeds around the fruit trees. Most of the equipment that can achieve weeding between the orchards is a backpack type Weeder, oblique weeder, hand-push weeder and rear-pull hanging weeder, this type of weeder has low working efficiency, poor passability, large labor consumption, low weeding rate, and great damage to fruit trees. of weeds still need manual removal

These all limit the development of orchard mechanization level, and also affect the orchard output

[0004] The existing weeding device also has the following disadvantages. The weeding height is fixed, and the grass roots cannot be eradicated, so that the weeds cannot be completely eradicated; it cannot adapt to the slope or ups and downs of the grass; and the armrest structure is not adjustable, and the operator is comfortable to use In the process of moving the car body, the handrail structure may cross the branches and cause damage to the fruit trees.
