Abstract

The invention discloses a potato harvester, which comprises a chassis and vibrating screen bars; a driving shaft is arranged on the front end of the upper part of the chassis; a gearbox which is connected with the gearbox of a walking tractor is arranged on the driving shaft; a stop lever is arranged on the gearbox; a driven shaft I, a driven shaft II and a driven shaft III are arranged sequentially from the rear to the front on the lower part of the chassis; a driving gear, a driven gear I and a driven gear II are sequentially arranged on the outer ends of the driving shaft, the driven shaft I and the driven shaft II on the same side; the driving gear is respectively connected with the driven gear I and the driven gear II through chains; a working blade is arranged on the front end of the lower part of the chassis, and is movably connected with the chassis; an eccentric wheel is arranged on the inner side of the driven gear II, and is movably connected with the working blade through a connecting rod, and by means of the rotation of the eccentric wheel, the variation range of the penetrating angle of the working blade is between 5 degrees and 15 degrees within a rotation cycle; depth-adjusting universal wheels are arranged on the rear end of the lower part of the chassis; and gears are respectively arranged on both ends of the driven gear I, and are connected with transmissions on both ends of the driven shaft III through chains.

Description

Technical field: [0001] The invention relates to an agricultural machine, in particular to a potato harvester with an adjustable shovel entry angle. Background technique: [0002] At present, the potato harvester is widely used in the mechanized production of farmland, and solves the shortcomings of low agricultural rate and low harvest rate caused by manual harvesting by farmers for a long time. However, most of the existing domestic advanced potato harvesters are imported from abroad. , generally used in plain areas, its body is huge, complex in structure, and it needs to be driven by a large tractor. For example, the application number is the invention patent of 201020229212.4, which discloses a potato harvesting machine, which is composed of a traction device and a harvesting implement. The rear training wheel mechanism, the car body assembly includes the front part of the car body, the rear part of the car body, the connecting parts of the car body, the front side pane...
