Description
Affiliated technical field
The present invention relates to a kind of farm equipment, particularly a kind of digger of potatoes that is used to gather in the crops the potato class.
Background technology
The primary structure of tomato digging harvester is at the frame front end clay digger, hitch frame and transmission device to be installed at present, driving-chain is installed on frame, the conveyer belt that drives in the frame by driving-chain rotates, and the vibratory sieve that is driven its vibration by eccentric wheel is installed at the conveyer belt rear portion.During use hitch frame is linked to each other with tractor, transmission device links to each other with the power take-off of tractor, drives tomato digging harvester by tractor and moves rotation with conveyer belt.After clay digger digs out the potato class, move backward, soil, potato class separated by conveyer belt, and then by vibratory sieve with soil with fall in the ground after the potato class is separated once more.The form of conveyer belt mainly contains two kinds, a kind of for shaking row's chain type conveyer belt, the structure of this conveyer belt is by two soft bands and be fixed on the closed circular that two steel bars between the soft band are formed, this conveyer belt is installed on the drive roll and passive cylinder of frame front and back, eccentric wheel is installed in the middle, in this conveyer belt rotation, make it produce up-down vibration, soil, potato are separated; Shake row's chain type conveyer belt owing to the structure more complicated, reliability extreme difference in the use, in case there is a steel bar from fixing soft band, to deviate from, the just possible thoroughly damage of whole piece conveyer belt, and its replacement cost is very high.The form of another kind of conveyer belt is a drum-type, the conveyer belt of forming by a plurality of cylinders, but owing to there is not dither functions, and the space of cylinder is less, is easily blocked by hard thing on the one hand, and soil, potato inferior separating effect on the other hand, it is lower to gather in the crops efficient.
Summary of the invention
The objective of the invention is to solve the defective that prior art exists, a kind of soil, potato good separating effect are provided, the digger of potatoes of simple in structure, long service life.
Technical scheme of the present invention is: a kind of digger of potatoes, comprise frame, be installed in the clay digger of frame front end, hitch frame and the conveying plant that is installed in the frame, conveying plant links to each other with driving-chain, the vibratory sieve that is driven its vibration by eccentric wheel is installed at frame rear end, it is characterized in that stationary distribution has the supporting riser parallel with the frame biside plate in above-mentioned frame, on each supporting riser, have elongated slot, the two ends of power transmission shaft are installed in rotation on the frame, one end of power transmission shaft links to each other with above-mentioned driving-chain, above-mentioned conveying plant is made up of the slider-crank mechanism that is installed between the two supporting risers, wherein an end of crank is fixed on the power transmission shaft, the other end links to each other with connecting rod by hinge, slide block is fixed on the other end of connecting rod, and slide block is removable to be installed in the elongated slot.
The above-mentioned slider-crank mechanism that is installed in the frame is two groups or more, by the parallel relative distribution to the rear end of frame front end.
Link to each other by driving-chain between the above-mentioned power transmission shaft more than two.
Driving-chain between the above-mentioned power transmission shaft more than two is chain or belt.
The present invention adopts slider-crank mechanism to replace existing conveyer belt type structure, has fundamentally solved existing digger of potatoes poor reliability, easily by problems such as hard thing block.Because in this device, crank is under the drive of power transmission shaft, rotate, and connecting rod is under the drive of crank, about doing, the compound motion of front and back, when being moved after along the supporting riser by forward direction by the soil that dug out and potato class, connecting rod is done from bottom to top, and promote backward meet motion, just the potato class in the soil well can be separated, soil falls along the slit between the supporting riser, and the potato class moves backward along the supporting riser.
In sum, that the technical program has is simple in structure, result of use good, long service life and be convenient to characteristics such as maintenance.
