Abstract
The invention relates to an automatic control potato harvester, formed by a digging shovel, a transmitter, a potato-soil separator, a guide groove, a frame, a depth limiting wheel, and walking wheels. The separator is driven by the straight motor. The invention comprises a stable part and a vibrating part, wherein, the vibration screen of vibrating part is sheet structure, while the amplitude is controlled by the compressed amount of damping spring in the stable part and the frequency is controlled by the electrical signal input into the straight motor. The separator utilizes the mechanical resonance theory. The invention will not hurt the potato, with less steel consumption and long service life.
Description
Technical field
The invention belongs to crops results and agricultural mechanization technical field.Be particularly related to a kind of automatic control potato harvester.
Background technology
In China, potato harvester is mechanical.It is the mode that adopts bar strip chain type vibration separator structure and sieve formula swing separating mechanism to combine that potato soil separates majority.Vibration is that the band tooth elliptic wheel (or band toothed wheel of other shape) that is mounted on the frame drives.The shortcoming of this separating mechanism is: 1. with toothed elliptic wheel (or band toothed wheel of other shape) contact position, bar strip (being reinforcing bar) amplitude is big.Leaving toothed elliptic wheel (or band toothed wheel of other shape) slightly at a distance, the amplitude of bar strip diminishes or basic friction.Because local amplitude is big, reinforcing bar very easily ruptures, and frame is also shaken from weld seam easily and split, and machine life is short.2. in the whole separation process of potato, soil, potato and reinforcing bar friction each other are bigger, and fraction time is longer, potato rubbing leather badly broken.3. after passing through bar strip chain type vibration separator structure, in potato, still there is a large amount of soil.Soil lands simultaneously with potato, and exposed potato rate is lower, leaks to receive seriously.4. consumption of power is big.When the single file operation, need 304 type tractors to drive, if the duplicate rows operation needs 654 type tractors to drive at least.
In the U.S., large-scale potato harvester mainly is to adopt the multistage screening conveyer belt.Finish different separation tasks, soil block, stone and cauline leaf are separated for every grade.The then two-stage conveyer belts that adopt of small-sized potato harvester more.Owing to be multistage transmission, the fraction time between potato and the conveyer belt is longer, potato rubbing leather badly broken, and also the traction power that consumes is generally bigger.Gondola potato harvester is similar substantially to China structurally.The then many employings of the potato harvester of Japan are mechanical.
Summary of the invention

(2) transmitting device is driven by stepper motor, and the vibration of vibratory sieve is driven by linear electric motors.
(3) circulus of vibratory sieve that will be at present the most frequently used makes laminated structure into, and rolled steel dosage is few, and complete machine is in light weight.
(4) by the motion mode of Tu Fa and potato on the control vibratory sieve, reduce friction, guarantee not damage potato.
(5) through behind the potato soil separating mechanism, potato thoroughly separates with Tu Fa, and exposed potato rate improves.
(6) potato soil separating mechanism has utilized the mechanical resonance principle, and consumed power is little, can reduce the tractive force of tractor greatly.
(7) the secondary realization of high-speed motion vibrated, and avoids the vibration bump to frame, and machine life is long.
