A bearing support structure applied to a double-blade bidirectional rotary lawn mower

Abstract

The invention relates to a bearing supporting mechanism for a double-edge bidirectional rotating mowing machine. The bearing supporting mechanism comprises a lower blade, a bottom hood and an output shaft. A center hole of the lower blade is installed on the output shaft. A disc spring and the bottom hood are arranged below the bottom end of the lower blade. The top of the disc spring is in contact with the outer circle of the bottom end of the lower blade to enable the lower blade to be isolated from the end part of the outer side of the bottom hood. The bottom of the disc spring is arranged at the upper end of a bearing. The disc spring is supported by the bearing and is tightly pressed on the bottom end of the lower blade. The left end and the right end of the bearing are respectively fastened on the output shaft and the inner side shell of the bottom hood. The bearing is tightened at the end of the output shaft through a bolt. The bearing supporting mechanism for the double-edge bidirectional rotating mowing machine has the advantages that since the bottom hood and the blade are separated from each other through the disc spring and the bottom hood and the output shaft are separated from each other through the bearing, the effect that the bottom hood does not rotate is realized, the collision between the bottom hood and the bottom and hard objects such as stones due to contact is eliminated, and the phenomenon that the bottom hood is cracked or seriously worn is avoided.

Description

technical field [0001] The invention relates to a double-blade bidirectional rotary lawn mower device, in particular to a bearing support structure applied to a double-blade bidirectional rotary lawn mower. Background technique [0002] Since the lawn of urban green belts, golf courses, and farm-level garden lights often needs to be trimmed regularly to maintain the overall beauty of the lawn and meet the needs of sports venues, this operation is a very heavy labor, so there are many kinds of operating machines. scheme and has been applied. Among these work machines, lawnmowers are widely used because they are compact and easy to operate. Because the upper and lower blades of the double-bladed bidirectional rotating lawn mower work in a shearing manner, it can cut grass smoothly and efficiently, and has good high-speed running stability, high cutting efficiency, and a wide range of applications. [0003] The bottom support structure of the existing double-bladed lawn mower...

AI Technical Summary

Problems solved by technology

[0003] The bottom support structure of the existing double-bladed lawn mowers is generally the same, and they are all pressed against the surface of the blade. Driven by the friction force generated by the pressing force, the bottom cover will rotate together with the blade. The bottom of the lawn mower will collide with hard objects such as the ground surface and stones, and the bottom cover will often be broken or worn to a high degree, resulting in failure to work normally

Some double-bladed two-way lawn mowers use high-hardness materials as the bottom cover, which makes the weight of the machine generally heavy, and the operator is prone to fatigue, which affects working hours and reduces work efficiency.
