Description
Technical Field
The invention relates to the field of cultivation machinery, in particular to a furrow plough with an adjustable interface position applied to a tractor.
Background
The turnplow is used for breaking soil blocks and plowing grooves to prepare for sowing, when in use, the turnplow needs to be hung on traction equipment, usually on a tractor to plowing, the turnplow is connected with the tractor through lifting lugs, the lifting lugs are fixedly arranged, and the positions and the distances between the lifting lugs are different for connecting the tractors with different horsepowers, so that the turnplow with different tractor types can be matched with the turnplow with fixed types to ensure the optimal connection between the turnplow and the tractor, and when the tractor is not matched with the tractor, for example, when the tractor with a wide wheel track is used for mounting the tractor matched with the tractor, the tail end of the first plow body turnplow blade of the plow is transversely separated from the right side tire by a larger distance, and the phenomenon of plowing missing can occur at the moment. In contrast, when the tractor with narrow wheel track is used for mounting the plough matched with the tractor with normal wheel track, the tail end of the first plough body ploughshare blade of the plough is transversely overlapped with the right side tyre, and the wheels advance along the furrows during the tillage, so that the phenomenon of heavy tillage can occur. So that the machine tool cannot reach the optimal use state, and the tractor track needs to be adjusted with time and effort. Therefore, the furrow plough with a fixed model is matched with each tractor type so as to ensure that no condition of no tillage missing or heavy tillage occurs in the tillage process.
In order to adapt to different crops, different agronomics and different application scenes, the track of the special type or modified tractor which is newly put forward for the small and medium horsepower section is different from that of the conventional tractor. The development investment of each farm tool manufacturer is less, and the produced plough tool is suitable for a special machine type or a refitted tractor, which is pushed out aiming at a conventional tractor, cannot follow the process. When the special type or modified tractor is connected with the conventional plough, the adjustable range is affected slightly, and compared with the plough matched with the conventional horsepower tractor, the situation that the wheel track is too wide and the phenomenon of no tillage occurs or the wheel track is too narrow and the phenomenon of heavy tillage occurs is the occurrence. The optimal use requirements for the tractor and the plow are as follows: 1. the traction force of the tractor is larger than or equal to the traction resistance of the plough, namely the power is matched; 2. the transverse distance delta between the end of the first plow blade of the plow and the right tire is 15mm most reasonably. Compared with the conventional plough with wide wheel tread, the delta value is larger, the ploughing missing exists, the wheel tread is narrow, the delta is more negative, and the phenomenon of heavy ploughing occurs. Therefore, for tractors with different center wheel tracks in the same horsepower section, the existing plow cannot meet the optimal use requirement at the same time.
