Description

Grass winding prevention mowing mechanism and mower

Technical Field

The invention relates to the technical field of mowing equipment, in particular to an anti-winding mowing mechanism and a mower.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

Mowers are agricultural machines used to cut growing grass or other crops that can be made into hay, or to beautify lawns and lay them on the ground. The research of the novel mower is developing towards high speed and energy saving. Mowers can now be broadly classified into the following categories: backpack (side-hung) mowers, rear-propelled mowers, riding mowers, tractor-suspended mowers, and the like.

With the adjustment of agricultural industrial structure, the development of orchard industry is more and more emphasized, the planting area of fruit trees and the yield of fruits are increased year by year, but with the increase of the planting area of an orchard, the contradiction between the mowing strength and the increase of the planting area is intensified, and the demand of people on orchard mowers is increasingly strong. However, the existing mowing machines are mostly used for mowing lawns, and the machines really used for mowing orchards are few. Since orchards and gardens are mostly located in mountainous and hilly areas, mowing in orchards or gardens has some special requirements, such as (1) obstacles (the height is generally about five centimeters) like broken stones and clods scattered in a working area. (2) The terrace area, i.e., the two-piece working area, has a height difference, and needs to climb when traveling between rows. (3) The operation area is complicated, the distance between trees is small, and the volume of the mower is not suitable to be too large. (4) When the fruit ripens, a certain height of grass is required for buffering in order to protect the fallen fruit, so it is preferable to leave the weeds at a height of 5 cm to 10 cm.

The inventor finds that the existing mower technology specially aiming at orchards or gardens is relatively backward, and the orchard mowing is finished by manpower or a hand-held self-propelled mower, so that the labor intensity of operation is high, the danger of the operation is increased, and the growth of fruit trees and the quality of fruits are influenced by delaying the farming season. The big shortcoming of the manual backpack mower is the grass winding problem, weeds can be wound on an exposed main shaft along with the rotation of a grass cutting rope during mowing, when the grass winding on the main shaft reaches a certain amount, the resistance can be increased, and the movement of the main shaft can be influenced. Therefore, the mowing disc needs to be frequently detached for cleaning during working, the manual workload is greatly increased in the process, and the weeding efficiency is influenced to a certain extent; and the height of mowing is not easy to control through manpower, so that the mowing is not uniform. The rear push mower needs a person to control the advancing direction of the mower through manpower after the mower advances, and the process often needs large force when the terrain is complex or climbing is needed, so that the manual workload needed by the rear push mower is often not large as that of a manual backpack mower when the rear push mower is used in an orchard or a garden. The riding mower and the tractor mounted mower mostly adopt a four-wheel type advancing method due to large volume, and the tree-to-tree distance is usually small and the road surface condition is complicated in the orchard, so that the large and medium sized mowers such as the riding mower and the tractor mounted mower cannot work normally in the orchard.

The existing various mowers cannot be well applicable to orchards or gardens, and various mowers have the defects of difficulty in advancing, difficulty in climbing, large manual workload and the like in the orchards or gardens, so that a mower applicable to the orchards and the gardens is urgently needed to perform weeding work with low cost and low manual workload on the orchards and the gardens with increasingly large area.
