Problems solved by technology

[0002] The plowshare assembly of the reversing plow is deep into the soil during operation, and may encounter obstacles such as stones and tree roots. If the plowshare tip collides with obstacles, it may The resistance of the plowshare increases suddenly or it is subjected to a large impact, which is easy to cause damage to the plowshare assembly. Therefore, it is necessary to design an anti-overload structure on the plowshare assembly to protect the plow.
[0003]In the prior art, most of the anti-overload structures use shear bolts, that is, when the plowshare resistance or impact exceeds the threshold, the safety bolts are sheared to release the impact or overload force, However, when the bolts are cut off, the plow cannot be used normally until the bolts are replaced again, and it needs to be shut down for maintenance and replacement parts

[0048] Please refer to Figure 1 to Figure 4, the present embodiment provides a plowshare assembly 100, including a plowshare 10, a plow column 20, a mounting seat 30 and a buffer cylinder 40, the plowshare 10 is fixedly connected to the plow column 20, and the plow column 20 is rotatably connected to the mounting seat 30, One end of the buffer oil cylinder 40 is connected to the plow column 20 , and the other end is connected to the mounting seat 30 . The plow column 20 can rotate relative to the mounting seat 30 under the action of external force to compress the buffer oil cylinder 40 . Since the plow column 20 is rotationally connected to the mounting seat 30, when the plowshare 10 encounters an obstacle, the plow column 20 is forced to rotate relative to the mounting seat 30, thereby compressing the buffer cylinder 40, and passing the resistance and impact generated by the obstacle through the buffer cylinder 40 absorption, thereby realizing the overload protection of part...

[0057] An embodiment of the present invention provides a reversible plow, including the above-mentioned plowshare assembly 100. If the reversible plow encounters an obstacle during the digging operation, the buffer cylinder 40 on the plowshare assembly 100 can absorb the resistance from the obstacle, thereby The damage to the plowshare assembly 100 is avoided, and there is no need to shut down the plow for maintenance, which improves the working efficiency of the turning plow.

[0058] Please refer to Figure 5 , the present invention provides an overload protection control method for the plowshare assembly 100, which can be applied to a tractor, and the tractor is used to mount the above-mentioned reversible plow to drive the reversible plow to perform operations. The tractor includes a controller, and the control method includes:

[0059] S10: receiving the overload signal of the buffer cylinder 40;

[0060] S20: Control the tractor to stop according to the overload signal...

Abstract

The embodiment of the invention provides a plough share assembly, a turnover plow, a plough share assembly overload protection control method and a tractor, and relates to the technical field of agricultural machinery. The plough share assembly comprises a plough share, a plough column, a mounting seat and a buffer oil cylinder, the plough share is fixedly connected with the plough column, the plough column is rotatably connected to the mounting seat, one end of the buffer oil cylinder is connected with the plough column, the other end of the buffer oil cylinder is connected with the mounting seat, and the plough column can rotate relative to the mounting seat under the action of external force to compress the buffer oil cylinder. By arranging the buffer oil cylinder, overload protection can be achieved after the plough share assembly encounters an obstacle, parts are prevented from being damaged, shutdown maintenance is not needed, and the operation efficiency of the tractor is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a plowshare assembly, a turning plow, an overload protection control method for the plowshare assembly and a tractor. Background technique [0002] The plowshare assembly of the reversing plow goes deep into the soil during operation, and may encounter obstacles such as stones and tree roots. If the plowshare tip collides with obstacles, the resistance of the plowshare may increase suddenly or be subject to a large impact. It is easy to cause damage to the plowshare assembly, so it is necessary to design an anti-overload structure on the plowshare assembly to protect the plow. [0003] In the prior art, the anti-overload structure mostly adopts shear bolts, that is, when the plowshare resistance or impact exceeds the threshold, the safety bolts are cut off to release the impact or overload force, but when the bolts are cut off, the plow cannot be used before the bo...
