Rapid hooking mechanism and hooking method

Abstract

The invention relates to a rapid hooking mechanism for supporting machines like a micro management machine, and a hooking method thereof, belonging to the technical field of agricultural machinery. The hooking mechanism comprises a pair of mounting plates with inner ends fixedly arranged on a tractor, and a hooking frame used for mounting a supporting machine, wherein the outer end of each mounting plate is provided with an upper limit rod and a lower limit rod with two extended ends and a through hole; the lower limit rod exceeds out of a plumb line of the upper limit rod; the hooking frame is provided with a pair of mounting frames extending towards the mounting plates; the inner side of the extended end of each mounting frame is respectively provided with an upper limit groove with a downward opening and a lower limit groove with an outward opening; the distance of two mounting frames corresponding to limit grooves match with the length of corresponding limit rods; the upper limit groove is provided with a top circular arc and a mounting hole matching with the upper limit rod; and the lower limit groove is provided with an inner-side circular arc and a mounting hole matching with the lower limit rod. The rapid hooking mechanism provided by the invention has simple structure; the whole process of hooking can be completed by one person, so rapidness and convenience are achieved; and hooking is reliable.

Description

technical field [0001] The present invention relates to a hooking mechanism of agricultural machinery, especially a quick hooking mechanism with supporting equipment such as a miniature multifunctional management machine (hereinafter referred to as a micromanagement machine), and also relates to a hooking method thereof, which belongs to the technical field of agricultural machinery . Background technique [0002] In hilly and mountainous areas, the plots are small, irregular, with steep slopes and many bends, and the roads for machine farming are narrow, making it difficult for four-wheel tractors to enter the land, and it is also difficult to popularize matching agricultural machinery. At present, the ones that are suitable for this area are mainly micro-management machines (for a typical structure, refer to the Chinese patent document whose notification number is CN99225069.2) or supporting agricultural implements of walking tractors, such as rotary cultivators, seeders, ...

AI Technical Summary

Problems solved by technology

The first type of hooking method needs to adjust the supporting equipment to align with the tractor hook interface, and ensure that the connecting screw holes are aligned, and then fix it with bolts. It requires high precision and difficult operation, and generally requires 3 to 4 people to operate; For the second type of attachment, it is also necessary to adjust the supporting equipment to align with the hitch interface of the tractor, and ensure that the connecting pin holes are aligned, and then connect with a bolt and fasten with two bolts. Compared with the first type of attachment, the attachment The precision requirement of the method is slightly lower, and the operation is relatively simple. Generally, 2 to 3 people are required to operate, but the connection is not firm, and the supporting equipment shakes seriously.
