Description

Multi-adaptive adjustable three-point suspension frame for farm tools

Technical Field

The invention belongs to agricultural machinery, and mainly relates to a multi-adaptive adjustable farm tool three-point suspension frame capable of being connected with suspension frames of 1, 2 and 3 types of tractors in a hanging mode.

Background

At present, the existing connection modes of agricultural implements and tractors are of a traction type and a suspension type, the latter is mainly hinged with upper and lower hanging points of a main frame of a deep scarifier, a seeder, a intertillage, fertilization and weeding machine and other implements through a three-point hanging device arranged at the rear of the tractor, the tractors need to be configured with corresponding tractors for different sizes of implements, the tractors are divided into 1, 2 and 3 types according to power output, the corresponding parameters of the hanging devices are also different, for example, the diameters of upper and lower hanging pin holes on an implement frame matched with the 1, 2 and 3 types of tractors are 19.3mm, 25.7mm, 32mm, 22mm, 28mm and 36.6mm, the span of the lower hanging point and the heights of the upper and lower hanging points are 683mm, 825mm, 965mm, 460mm, 610mm and 685mm respectively, and most existing machine frames adopt a mode of integral welding and partial assembly, and can only be adjusted within the range of 1 type of tractor generally, and the cross-type hitching is difficult, and meanwhile, when the output power of the tractor is increased, the width of the machine tool needs to be increased so as to achieve the function of hitching a plurality of operation single bodies, and the width of the welding rack of the existing machine tool is not adjustable and has poor adaptability. Therefore, the design of the frame of the agricultural implement which can be selectively hung on 1, 2 and 3 types of tractors and has adjustable width has important practical significance.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the accompanying drawings:

a multi-adaptive adjustable farm implement three-point suspension frame is characterized in that a lower suspension 21 is fixedly arranged on front side beams 18 on two sides of the front end of a main frame 30 through a front clamping plate 19 and a

front bolt group
