Ridging ploughshare connecting device of plate-type retest tillage implement

Abstract

A ridging ploughshare connecting device of a plate-type retest tillage implement comprises a rod ruler fixing sleeve, an upper clamping plate, a lower clamping plate, fastening bolts and a jackscrew and is characterized in that the rod ruler fixing sleeve is connected with the upper clamping plate and the lower clamping plate, the upper clamping plate and the lower clamping plate are connected with the fastening bolt, the rod ruler fixing sleeve is connected with the jackscrew, and the rod ruler fixing sleeve, the upper clamping plate and the lower clamping plate are matched with an implement square beam and are fixed through the fastening bolts. Due to the fact that the plate type structure design is adopted, the contact face between the ridging ploughshare connecting device and the implement square beam is large, a connecting structural mode in the prior art is changed, the ridging ploughshare connecting device is firm and reliable in connection and does not easily loosen or deform, is not easily abraded, it is ensured that a soil piercing angle of a ridging ploughshare is constant, the implement is not easily changed, and the expected technical effect of improving tillage quality is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a ridge share connection device for a plate-type retest tillage implement. Background technique [0002] At present, U-shaped clips are used as connecting parts in the connection methods of agricultural machinery and tools, especially the connection between the ridge pole ruler or the deep pine rod ruler and the implement beam. The use of U-shaped clips is even more unique in the same field. The conventional structural design method used by technicians, the advantage of the U-shaped card structure is that it is simple in structure, but it also has many defects. Generally, a ridge share or a subsoiling shovel is directly connected with the implement beam by more than two U-shaped cards. , since the U-shaped clip is bent by a threaded screw at both ends, there is always an R angle at the bending point, and it is impossible to adapt to the square steel beam. Therefore...

[0002] At present, U-shaped clips are used as connecting parts in the connection methods of agricultural machinery and tools, especially the connection between the ridge pole ruler or the deep pine rod ruler and the implement beam. The use of U-shaped clips is even more unique in the same field. The conventional structural design method used by technicians, the advantage of the U-shaped card structure is that it is simple in structure, but it also has many defects. Generally, a ridge share or a subsoiling shovel is directly connected with the implement beam by more than two U-shaped cards. , since the U-shaped clip is bent by a threaded screw at both ends, there is always an R angle at the bending point, and it is impossible to adapt to the square steel beam. Therefore, under the condition of heavy load, the U-shaped There is a torque on the opposite beam of the card, and the torque disappears when the car is stopped. The U-shaped card is easy to wear, loosen or deform, especially after wearing, loosening or deforming, it will change the angle of entry of the shovel, which will easily change the performance of the implement and affect the quality of tillage.
