Mini-tiller and handrail rack adjusting device thereof

Abstract

The invention discloses a handrail rack adjusting device, which comprises a lifting adjusting mechanism. The lifting adjusting mechanism comprises a lifting handle, a lifting stay rope, a lifting positioning piece, a lifting positioning plate, a lifting positioning tube and a lifting resetting member, wherein the lifting handle is hinged with a fixed handle of equipment; the lifting stay rope is connected with the lifting handle; the lifting positioning piece is connected to the tail end of the lifting stay rope, and the dimension of the upper end of the lifting positioning piece is larger than that of the lower end; the lifting positioning plate is fixedly connected with a handrail rack of the equipment, a plurality of lifting positioning holes arranged in the same vertical face are arranged on the lifting positioning plate, and the diameter of each lifting positioning hole is ranged from the size of the lower end of the lifting positing piece and the size of the upper end of the lifting positioning piece; the lifting positioning tube can rotate along a connecting line of central points of the lifting positioning holes, is fixedly arranged on the handrail rack and is internally sleeved with the lifting positioning piece; and two ends of the lifting resetting member are respectively positioned with the end surfaces of the lifting positioning piece and the lifting positioning tube in a propping way. The invention also discloses a mini-tiller comprising the handrail rack adjusting device. According to the handrail rack adjusting device, the stability in position adjustment of the handrail rack can be ensured, and the time for position adjustment of the handrail rack is shortened simultaneously.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an adjusting device for an armrest frame. The present invention also relates to a micro tillage machine provided with the above-mentioned armrest adjustment device. Background technique [0002] Tiller is a kind of agricultural machinery powered by small diesel engine or gasoline engine, which has the characteristics of light weight, small size and simple structure. The tiller can move freely in the field, which is convenient for users to use and store, and solves the disadvantage that large-scale agricultural machinery cannot enter the fields in mountainous areas. Therefore, it is widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. The micro tillage machine is used in conjunction with corresponding tools to perform operations such as pumping water, generating electricity, spraying chemicals, spraying, etc., and can also be towed...

AI Technical Summary

Problems solved by technology

When the pull rod spring positioning type is used, although the adjustment process of the armrest frame is relatively stable, since people always operate through the handle on the armrest frame during normal operation, and the pull rod is connected to the lower end of the armrest frame, the adjustment process needs to be adjusted between the pull rod and the armrest. Frequent switching between the armrests makes the adjustment time of the armrest frame too long and the work efficiency is low
