Problems solved by technology

The currently used armrest frame height adjustment mechanism is mainly the tooth plate meshing adjustment mechanism (such as the patent No. CN 203015415 U) or the bayonet type facility adjustment mechanism (such as the patent No. CN 203261679 U). Different operators work in different There will be different most comfortable operating positions when operating on the work site, and these mechanisms are difficult to achieve continuous adjustment of the height of the armrest frame and the structure is complex, so it is difficult for the operator to always be in the most comfortable position for operating the tiller

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 and figure 2 As shown, the present invention includes an armrest frame 2, an armrest seat 1, a spiral tube 7 and a locking device; the armrest frame 2 is formed by bending a round tube, and its general shape is "U" shape, narrow at the front and wide at the rear. 2. The front is low and the rear is high, and it is bent downward at the tail end of the armrest frame 2, and the degree of bending is determined according to needs.

[0017] The armrest base 1 is provided with two groups of through holes, each group of through holes includes two through holes, two U-shaped bolts 4 are installed in the two groups of through holes on the armrest base 1, and the U-shaped bolts 4 connect the armrest frame 2 The cross beam at the bottom is fixed on the armrest seat 1, and the armrest frame 2 can rotate relative to the armrest seat 1.

[0018] The beam a...

Abstract

The invention provides a height adjustment mechanism for a handrail of a mini tiller. The height adjustment mechanism for the handrail of the mini tiller comprises a handrail frame, a handrail seat and a threaded tube. The handrail frame is rotatably mounted on the handrail seat and provided with a seat lug, a screw rod is hinged onto the seat lug, and a screw rod is hinged onto a base which is arranged on the handrail seat. Thread directions of the screw rod on the handrail frame and the screw rod on the handrail seat are opposite, and the screw rod on the handrail frame and the screw rod on the handrail seat are connected with two ends of the threaded tube respectively. The height adjustment mechanism is simple in structure and small in space occupation; when the height adjustment mechanism is used, ascending and descending of the handrail frame can be realized by rotating the threaded tube with a spanner or hands, and a hoop can be loosened or locked by screwing a bolt handle with hands, so that convenience in adjustment is achieved; height adjustment is realized by means of threads, and wide height range and continuity in ascending and descending of the handrail frame can be realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a mechanism for adjusting the height of a handrail of a tiller. Background technique [0002] Tillers are agricultural machines used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. In some areas with relatively small plots (such as greenhouses and terraced gardens), large-scale agricultural machinery cannot enter, and micro-tillage machines are playing an increasingly important role. They are the best choice for farmers and consumers to replace cattle farming. Tillers require operators to hold the armrests to control their direction when they are working. Since different people have different heights, the height of the armrest must be adjustable. By adjusting the height of the armrest, the operator can be in a comfortable operating state. The currently used armrest frame height adjustment mechanism is mainly the tooth plate ...
