Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural machinery technology, specifically to an automatic row alignment driving detection device and its row alignment method for a sugar beet topping and pruning machine. Background Technology
[0002] Beetroot, one of the raw materials for sugar production, is harvested in stages, which consist of three parts: vine removal and topping, digging and separating, and collecting and piling. The main machinery used in the vine removal and topping stage is a topping and vine-removing machine, which is a combination of the topping and vine-removing implement and a wheeled tractor. During beet harvesting, because beet vines and leaves are lush, the rows of crops are not easily judged by the naked eye. The operator needs to concentrate on judging the position of the crop rows and constantly fine-tune the driving direction to ensure that the tractor's trajectory always follows the crop rows, allowing the topping and vine-removing implement to achieve precise vine removal and topping. Otherwise, the tractor tires will crush the beet roots, causing harvest losses. Therefore, the workload for operators is heavy, and the work efficiency is low, creating an urgent need for automated row-aligning driving technology.
[0003] Detecting row alignment deviation in beet topping and sapling trimmers is the primary task in achieving automated row alignment driving technology. Currently, row alignment deviation in beet topping and sapling trimmers is mainly detected through satellite positioning or row alignment sensors. Field environments are complex and variable, making it impossible for operators to create ideal straight planting rows during beet sowing, whether manually or using navigation systems. In the topping and sapling trimming stage, because the position information of the beet crop rows is difficult to obtain accurately, existing agricultural machinery GNSS navigation systems cannot accurately calculate the relative position information between the tractor and the crop rows, thus hindering automated row alignment driving of beet topping and sapling trimmers.

The number of the guide blocks 10 is two, and the two guide blocks 10 are fixedly connected with the two telescopic sleeves through bolts.
[0039] The number of the rear mounting plates 9 is two, and the two rear mounting plates 9 are both of a bending structure, one end of each of the two rear mounting plates 9 is hingedly connected with a guide block 10; the parallelogram profiling frame 8 comprises two parallelogram profiling frames, one end of each of the two parallelogram profiling frames is hingedly connected with the other end and the middle part of the rear mounting plate 9, the other end of each of the two parallelogram profiling frames is hingedly connected with a hinge member, and the hinge connection mode of the two ends of each of the two parallelogram profiling frames is shaft hole cooperation; it should be noted that the middle parts of the two parallelogram profiling frames are connected with a rod, and the rod is used to maintain the heights of the two parallelogram profiling frames at the same level and ensure the stability during the operation of detecting the road. Each of the two parallelogram profiling frames is composed of two hollow rectangular pipes, and the head and tail ends of each of the two hollow rectangular pipes are welded with sheet metal for mounting the elastic rubber assembly 11. The elastic rubber assembly 11 has a circular hole in the middle and is connected with the front frame 1 and the rear mounting plate 9 through shaft hole cooperation.
