Description

Technical Field

[0001] The utility model relates to the technical field of rotary tillers, in particular to an anti-fracture and anti-falling rotary blade seat for rotary tillers. Background Art

[0002] A rotary tiller is an agricultural machine mainly used for tilling land, turning soil and mixing organic matter in the soil, such as crop residues, fertilizers, etc. In modern agricultural production, a rotary tiller is a very critical equipment. It can provide loose and uniform soil conditions, creating a good foundation for subsequent agronomic operations such as sowing, transplanting, weeding and spraying pesticides. The rotary knife seat in the rotary tiller is one of the core components of the rotary tiller. It is installed on the knife shaft of the rotary tiller to support and fix the rotary tiller blade. In the existing rotary tillers, when the rotary knife seat is rotating, the blade will produce a great stress concentration when colliding with the rock during operation. This may cause the blade to break due to the impact force, shortening the service life of the blade and affecting the normal operation of the rotary tiller. At the same time, strong collisions can easily damage the fixing structure of the knife seat, causing the knife seat to fall off the knife shaft, affecting the tillage effect of the rotary tiller and increasing the maintenance cost and downtime of the equipment. Therefore, we propose an anti-breakage and anti-falling rotary knife seat for a rotary tiller to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the existing rotary tillers, when the rotary cutter seat is rotating, the blade will produce great stress concentration when colliding with the rock, which may cause the blade to break due to the impact force, shortening the service life of the blade and affecting the normal operation of the rotary tiller. At the same time, the strong collision can easily damage the fixing structure of the cutter seat, causing the cutter seat to fall off the cutter shaft, affecting the tillage effect of the rotary tiller and increasing the maintenance cost and downtime of the equipment.
