Description

Self-propelled garlic combine harvester

technical field

The invention relates to the technical field of garlic harvesting equipment, in particular to a self-propelled garlic combine harvester with higher degree of mechanization and higher harvesting efficiency.

Background technique

The garlic harvester is an agricultural machine that uses machinery to harvest garlic in agronomic links such as digging, plucking, cutting stems (cutting stems), collection, and transportation when garlic is mature. The degree of mechanization of the existing garlic harvesters is not high, and generally only one or several agronomic links can be realized. For example, some garlic harvesters can only realize the digging of garlic, and the later processing is all done manually. The machine can only realize the agronomic links of digging and cutting the poles, but cannot realize the agronomic links of online bagging. Through the analysis of the existing garlic harvesters, it can be seen that the existing garlic harvesters have low degree of mechanization and complete agronomic links as a whole. less and less harvesting efficiency. The main factors restricting the further development of the garlic harvester are as follows: First, the digging resistance is large. The garlic harvesting is different from the traditional crops of wheat and corn. The garlic harvesting must be excavated first. The excavation shovel is directly obliquely inserted into the ground for excavation. When excavating, the resistance is very large, and the engine power is too large, resulting in insufficient power of the garlic harvester, low harvesting efficiency, and no excess power to complete other agronomic links; the second is the cutting rod of the plucking and cutting rod. The accuracy is low, and the length of the cutting rod is different, which is not conducive to the collection and processing of garlic in the later stage. Third, the existing garlic harvester cannot realize the agronomic link of online bagging, or has the function of online bagging, but the bagging speed seriously lags behind the garlic harvest. Speed, in order to match the bagging speed, the existing garlic harvester has to reduce the running speed, and carry out online bagging at the expense of harvesting efficiency. Due to the above-mentioned defects of the existing online bagging equipment, it is difficult to be installed on the garlic harvester. promotion and application. Therefore, in order to improve the working performance of the garlic harvester as a whole, it is necessary to improve or change at least one key influencing factor in the existing garlic digging, plucking and cutting rods and in-line bagging structures, in order to improve the harvesting efficiency of the garlic harvester. and degree of mechanization.
