Potato harvester

Abstract

The invention discloses a harvester for potato, comprising: digging and spading device, rod chain separating device, screen swing separator, gear box drive device, main frame, traction device, and drive supporting device; drag chain axis, shaker axis, lower drag chain axis and guiding wheel axis are all integral. The structure of main frame is left and right side board, the structure of lower part of which is semi-circle orifice. The spading slice projects out of integral machine. The elevation angle between rod chain separating device and horizontal surface is reduced by 15-20 deg. The invention is characterized in that: the harvester never hip for 20-30 days' continuous work, the resistance is small, and efficiency is high. The design of integral axis makes the force be rational, operation stable and maintenance convenient. The projection of spading slice makes it work without influence of any other parts, and the tillage depth more stable.

Description

Technical field: [0001] The invention relates to a potato harvester, which belongs to the field of agricultural machinery. Background technique: [0002] The current potato harvesters are different in structure, but most of them have the following disadvantages: (1), the input shaft of the gearbox is mostly supported by a single wall, that is, it is fixed with two disc bearings on the front wall of the box; (2), the excavating shovel Most of the coulters are aligned with the disc coulter or slightly in front of the shovel blades. There is also a structural design of the shovel blades and the left and right side panels of the whole machine in front of the ground. The above structures have been proved to affect the shovel blades in the production and use. , so as to affect the stability of the tillage depth; (3), the swing arm structure is complex, difficult to manufacture, and the failure rate in use increases the manufacturing cost of the whole machine by more than 1,000 yua...

[0002] The current potato harvesters are different in structure, but most of them have the following disadvantages: (1), the input shaft of the gearbox is mostly supported by a single wall, that is, it is fixed with two disc bearings on the front wall of the box; (2), the excavating shovel Most of the coulters are aligned with the disc coulter or slightly in front of the shovel blades. There is also a structural design of the shovel blades and the left and right side panels of the whole machine in front of the ground. The above structures have been proved to affect the shovel blades in the production and use. , so as to affect the stability of the tillage depth; (3), the swing arm structure is complex, difficult to manufacture, and the failure rate in use increases the manufacturing cost of the whole machine by more than 1,000 yuan (RMB); (4), the guide wheel, the chain The half-shaft design of the wheel and the vibrating wheel is complicated in structure, unreasonable in force, inconvenient in use and maintenance, and high in failure rate; (5) There is a large drop between the screen surface of the sieve-type swing separation mechanism and the bar conveyor chain, which mostly causes potato rubbing loss
