Multifunctional weeding rotary cultivator for orchard

Abstract

The invention relates to the field of agricultural machinery and specifically relates to a multifunctional weeding rotary cultivator for an orchard. The multifunctional weeding rotary cultivator comprises a rack, a rotary blade shaft and rotary blades; a soil crushing grinding roller is located at the rear side of the rotary blade shaft; a double-belt belt wheel at one end of the rotary blade shaft is connected with an output belt wheel of a driving motor; a weeding mechanism comprises a steering gear and swinging arms; the steering gear is mounted on the rack and is in transmission connectionwith the double-belt belt wheel; the swinging arms are mounted at the outer side of the rack; a supporting sleeve is vertically and fixedly mounted at the tail ends of the swinging arms; the middle part of the upper swinging arm is elastically connected with the rack through a returning tension spring; the supporting sleeve movably sleeves a transmission shaft; a cutter disc and cutting blades are mounted below the transmission shaft; a transmission belt wheel in transmission connection with the steering gear sleeves the upper side of the transmission shaft; an avoiding protection ring sleeves a part, located at the upper side of the cutter disc, outside the supporting sleeve; the diameter of the avoiding protection ring is greater than the diameter of a maximum working region for rotarycutting of the cutting blades. By adopting the device, weeds at the periphery of fruit trees at two sides can be removed in a rotary cultivation process.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a multifunctional weeding rotary tiller for orchards. Background technique [0002] At present, in orchards and garden planting, garden plants are mostly planted in rows, which is convenient for later interplanting and mechanical automation for weeding and other operations. Although agricultural machinery such as rotary tillers and weeders can pass through the open space between two adjacent vertical rows of plants, they cannot meet the operation requirements of orchards with different row spacing and plant spacing, and it is difficult to eliminate weeds around the fruit trees. The position between the plants in the same tandem cannot be covered by a weeding knife or a rotary tiller, so in each tandem, the area between two adjacent trees becomes a blind spot for operation, and weeds will be in the area. grow in this blind zone. At the same time, due...

Problems solved by technology

At the same time, due to the growth process of trees, some trees grow fast, some trees grow slowly, and the tree thickness varies, resulting in inconsistent tree spacing. Therefore, it is relatively difficult to automate weeding in this area through automatic weeding equipment. ;In addition, the volume of the weeding equipment itself is relatively large, the distance between trees is small, and the equipment cannot freely walk through the distance between trees, so it is very easy to accidentally injure trees during the walking process of the equipment, and the automatic weeding operation of the equipment is difficult. At present, the existing weeding Although there are a few machines that can work between fruit trees, their adaptability and automation are low
