Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery suspension, in particular to an agricultural machinery suspension device. Background Art

[0002] An existing patent (publication number: CN118303165A) proposes an agricultural machinery suspension device, including a hook and a ball head. The hook is provided with a spherical groove and a mounting groove. The spherical groove is located near one end of the hook hook tip and in front of the mounting groove. The ball head is arranged in the spherical groove. The bottom of the hook is provided with a receiving groove. The bottom of the spherical groove is provided with a through groove that passes through the receiving groove. Two mounting plates are symmetrically fixed in the mounting groove. However, this device "enables the ball head to rotate slightly during tillage, causing the force position of the spherical surface to change." After the ball head rotates, the angle of the agricultural machinery may change. After the angle of the agricultural machinery changes, the agricultural machinery lacks the ability to reset, so that the agricultural machinery may deviate when encountering an obstacle, affecting the subsequent tillage effect. Summary of the Invention

[0003] In response to the above-mentioned deficiencies in the prior art, the present utility model provides an agricultural machinery suspension device, in which, during farming operations after connection is completed, the longitudinal arrangement of the upper spring connecting ring, the spring mounting column, and the longitudinal return spring can enable the agricultural machinery to perform partial longitudinal displacement when encountering an obstacle. At the same time, the connection between the outer rotating connecting platform and the inner rotating connecting platform and the rotation return spring between the main bearing column and the transition mounting platform can enable the agricultural machinery to perform partial angle change when encountering an obstacle. After crossing the obstacle, the longitudinal return spring and the rotation return spring will assist the agricultural machinery in resetting, thereby ensuring that the farming operation is carried out smoothly.

Beneficial effects

[0008] 1. When the utility model is used to hang agricultural machinery, after removing the outer suspension hook, the connecting rod of the agricultural machinery is inserted into the inner suspension hook slot. After reconnecting the outer suspension hook, the outer suspension hook slot will be clamped on the other side of the connecting rod of the agricultural machinery to complete the connection of the agricultural machinery. During the farming operation after the connection is completed, the longitudinal arrangement of the upper spring connecting ring, the spring mounting column, and the longitudinal return spring can enable the agricultural machinery to perform partial longitudinal displacement when encountering an obstacle. At the same time, the connection between the outer rotating connecting platform and the inner rotating connecting platform and the rotation return spring between the main bearing column and the transition mounting platform can enable the agricultural machinery to partially change its angle when encountering an obstacle.
