Problems solved by technology

The existing handrails of micro tillage machines use two toothed disc mechanisms to adjust the vertical height and left and right positions respectively. Not only the structure is relatively complicated, but the production cost is high, and the convenience and reliability of the adjustment operation are poor.

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0020] Such as figure 1 , figure 2 As shown, the armrest frame 1 is a "U" shape with a closed front end and an open rear end, which is formed by bending a round tube. The width of the armrest frame 1 gradually increases from front to back; And the rear end of the armrest frame 1 is bent downward, and the specific angle of bending is determined according to actual needs. The transverse section of the front end of the armrest frame 1 passes through the protective cover 2, and the transverse section of the front end of the armrest frame 1 is hinged to the protective cover 2 through two U-shaped bolts arranged side by side on the left and right sides. The top surface of cover 2 is locked by cap nut 8, and guard cover 2 is fixedly arranged on the tail end of armrest seat 3 by welding.

[0021] Such as figure 1 , figure 2 As shown, a toothed plate 4 is arran...

Abstract

The invention discloses a bending handrail assembly of a minitiller. A transverse section at the front end of a handrail frame (1) is hinged with a protecting hood (2); a toothed plate (4) is fixed at the bottom of the transverse section at the front end of the handrail frame (1); a bayonet lock (5) is locked into a neck (4a) of the tooth plate; the bayonet lock (5) is arranged on a wrench (6); the front end of the wrench (6) is hinged with a base (3a); a tension spring (7) is arranged between the bayonet lock (5) and a handrail base (3); the bottom of the front end of the handrail base (3) is sleeved into a positioning column (10); a plurality of positioning holes (11b) are formed on a top plate (11a) of a riser base (11); the lower end of a lifting rod (13) extends inside a positioning pipe (12) and is connected with the upper end of an expansion head (14); the lower end of the expansion head (14) is inserted into one positioning hole (11b). By adopting the bending handrail assembly, the upper and lower heights and the left and right positions of the handrail frame can be adjusted according to the requirements; the bending handrail assembly is not only large in adjusting range, but also convenient and reliable to operate.

Description

technical field [0001] The invention belongs to the technical field of micro-tillers, and in particular relates to an elbow handrail assembly on a micro-tiller. Background technique [0002] In order to facilitate the operation of people of different heights, the armrests on the tiller can generally be adjusted in height up and down as needed; and in order to meet the operating needs of different occasions, the armrests can also be adjusted in left and right positions as needed. The existing handrails of micro-tillers are used to adjust the vertical height and left and right positions respectively through two toothed disc mechanisms. Not only the structure is relatively complicated, but the production cost is high, and the convenience and reliability of the adjustment operation are relatively poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a convenient and reliable micro tillage machine elbow handrail assem...
