Small-sized boxing type potato harvesting combined machine

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a small boxing type potato harvesting combined machine. The small boxing type potato harvesting combined machine comprises a rack, a traction hanging frame, a composite digging shovel, a transmission device, a vibration separation device, an eccentric wheel mechanism and a supporting wheel, wherein the composite digging shovel, the supporting wheel and the vibrating screen are connected to the lower end of the rack correspondingly, and the eccentric wheel mechanism is installed at the upper end of the rack. The eccentric wheel mechanism is used for simultaneously driving the digging shovel and the vibrating screen, so that the digging shovel and the vibrating screen simultaneously reciprocate in the horizontal direction, and the design concept of coaxial transmission but different amplitudes is adopted, so that the horizontal amplitude of the vibrating screen is increased while the digging resistance is reduced as far as possible, potatoes and soil are separated more thoroughly in addition, a rotary barrel frame collecting device is designed, and the integrated operation process of digging, soil screening and boxing is achieved, and another function is to further realize potato-soil separation, so that the collected potatoes are cleaner, meanwhile, vibration optimization is conducted on the digging shovel, the resistance of the machine is reduced, and meanwhile the digging shovel and the vibrating screen are connected more compactly.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a small box-packed combined potato harvesting machine. Background technique [0002] In response to the development needs of the potato industry in Northwest my country, the topography of Gansu Province is mainly characterized by many slopes and few rivers, and the plots are relatively small, mostly in the form of terraces. Seriously restricting the development of potato industry in Gansu Province, my country is a large agricultural country, which largely leads to low income of farmers in Northwest China and restricts the development of Northwest China. In the survey, we investigated the planting pattern and distribution of potatoes in Gansu Province, cultivated land resources and soil types, supporting power of walking tractors, acceptance of machine excavation, damage rate of potatoes by machine excavation, and excavation rate, and found that domestic The defecti...

Problems solved by technology

The above-mentioned equipment is bulky, and it is difficult to be used in small plots. At the same time, due to the interference of the plastic film, the transmission parts will be entangled with residual film, which will affect the service life of the whole machine.

[0004] To sum up, the existing potato excavators are generally of the fixed digging shovel type, which has a low efficiency of digging into the soil, and it is difficult to separate the dug potatoes from the soil, which directly le
