Description

Plough with adjustable joint position

Technical Field

The utility model relates to a farming machinery specifically is a be applied to tractor interface position adjustable furrow plough.

Background

The furrow plough is used for breaking soil blocks and ploughing out of a groove to prepare for sowing, the furrow plough needs to be hung on traction equipment during use and usually hung on a tractor to plough, the furrow plough is connected with the tractor through a lifting lug, the lifting lug is fixedly arranged, the positions and the intervals for connecting the lifting lugs by tractors with different horsepower are different, so that the furrow plough matched with fixed models of each tractor type is realized, the best connection between the furrow plough and the tractor is ensured, when the tractor is not matched with the plough, for example, when a tractor with a wide wheel spacing is hung on a tractor to load a tractor matched with the plough with a normal wheel spacing tractor, the tail end of a first plough body plough blade of the plough has a larger distance with a right tire transversely, and at the moment, the phenomenon of plough missing can occur. On the contrary, when a tractor with a narrow wheel track is used for hanging a tractor with a normal wheel track to form a matched plough, the tail end of the first plough body share edge of the plough and the right tire are transversely overlapped, and the wheel moves forward along the plough furrow during cultivation, so that the phenomenon of replanning can occur. So that the machine tool can not reach the optimal use state, and the time and labor are wasted to adjust the wheel track of the tractor. Therefore, each tractor type is also required to be matched with a fixed-type furrow plough so as to ensure that no missing ploughing or re-ploughing occurs in the ploughing process.

In order to adapt to different crops, different agricultural techniques and different application scenes, the track of a special type or a modified tractor newly proposed by a middle-small horsepower segment is different from that of a conventional tractor. And each farm machinery manufacturer has less research and development investment, and the produced plough is suitable for a special type or a modified tractor and cannot follow the process aiming at the conventional tractor. When the special tractor or the modified tractor is connected with the conventional plough tool in use, the adjustment range is small, and compared with the plough tool matched with the conventional horse-power tractor, the plough tool has the condition that the wheel track is too wide and the phenomenon of missing ploughing occurs, or the plough tool has the condition that the wheel track is too narrow and the phenomenon of replanning occurs. The optimal use requirements of matching the tractor and the plough tool are as follows: 1. the traction force of the tractor is more than or equal to the traction resistance of the plough, namely the power is matched; 2. the transverse distance between the tail end of the first plough body share edge of the plough and the tire at the right side is most reasonable about 15 mm. Compared with the conventional plough, the wheel track is wide, the value is large, no tillage exists, the wheel track is narrow, the value is negative, and the phenomenon of replanting occurs. Therefore, for tractors with the same horsepower section and different center wheel track distances, the existing plough tool cannot simultaneously meet the optimal use requirement.
