In technical solutions of the utility model, filled between the connecting components such as the axis and rack of each rotation, lateral support frame There is bearing.

Damping spring is provided with (in figure between the upper part of double vibrating screen and lower part upper part of double vibrating screen and rack 28 Do not provide), one end of damping spring corresponding with upper part of double vibrating screen is connected with the first connecting plate 37, the other end and rack phase Even；One end of damping spring corresponding with lower part double-deck screen shale shaker is connected with the second connecting plate 38, and the other end is connected with rack, into One step plays the role of bumper and absorbing shock to vibrating screen.

The service condition of the utility model is, after engine 19 starts, by filling sprocket wheel, chain, belt on the rack The power transmission structures such as wheel and belt (not providing in figure) give power transmission to each dynamical element, drive all parts operating, The knife that loosens the soil of hack feeding device shovels out little particle root crop fruit from soil, is carried out by hack knife to bulk soil It is preliminary broken, and first conveyer belt is sent by guide rod 131, the rear end of first conveyer belt by pressure roller to bulk soil into It is sent into upper part of double vibrating screen after one step is broken, is fed forward by vibration, during vibrating transportation, most of little particle Root crop fruit and lesser soil block fall on the first lower layer sieve plate 25b simultaneously by the first sieve pore on the first upper sieve plate 25a Conveying direction along first lower layer's sieve plate continues vibrating transportation forward, and during vibrating transportation, smaller soil block passes through the Two sieve pores, which are separated, falls into upper layer delivery board 26a, and the bulk soil left on the first upper sieve plate 25a is from the first of extension The discharge end of upper sieve plate 25a is fallen into be backfilled on the ground, and the soil fallen on the delivery board 26a of upper layer is equally fallen by vibrating transportation Enter and backfill on the ground, upper layer delivery board 26a is closed bottom plate, and in tilting down setting, it is this slided when vibrating send the earthwork Formula ensure that the soil screened out is smoothly discharged, and effectively prevent the accumulation of soil, little particle root crop fruit is under first Continue to be fed forward and fall into the second lower layer sieve plate 26b vibrating transportation in the opposite direction on layer sieve plate 25b, it is right during vibrating transportation Little particle soil block further sieves, and finally remaining little particle root crop fruit and small part soil are shaken by lateral transfer Dynamic sieve is sent into rewinding hoisting mechanism, the top of rewinding elevator is sent to by the scraping disc on rewinding hoisting mechanism conveyer belt, finally The recycling (as shown in arrow c, d in Figure 18) that harvest case completes little particle root crop fruit is fallen by delivery sheet 35, it is described The conveying direction of upper part of double vibrating screen and lower part double-deck screen shale shaker is on the contrary, substantially prolong screening distance, while upper part of double Vibrating screen and lower part double-deck screen shale shaker vibrate upper part of double vibrating screen and lower part bilayer by the progress power transmitting of transmission arm 30 The direction of vibration of sieve substantially increases the stability of complete machine on the contrary, vibration force is cancelled out each other.

Compared with prior art, the utility model structure novel is unique, and overall design is solid and reliable, and transmission rationally, operates Simply, mechanical quickly harvest is carried out to little particle root crop, and by multi-stage screening, extends the length of separation screening And the time, while the conveying direction of upper part of double vibrating screen and lower part double-deck screen shale shaker is on the contrary, substantially prolong screening distance, always Length reaches 5-7 meter, has reached that good screening effect is good, substantially increases the net rate that goes out of fruit, upper part of double vibrating screen is under Portion's double-deck screen shale shaker carries out power transmitting by transmission arm, makes the direction of vibration of upper part of double vibrating screen and lower part double-deck screen shale shaker On the contrary, vibration force is cancelled out each other, the stability of complete machine is substantially increased, it is in tilt down the close of setting that the soil block screened out, which passes through, Close upper layer delivery board discharge backfill, it is this while vibration while slide send a cubic metre of earth formula, ensure that the soil screened out is smoothly discharged, Effectively prevent the accumulation of soil, pressure roller and hack knife are driven by belt, therefore occur stone in locality, block hack knife or When pressure roller, belt can skid, to ensure that equipment will not can be in first conveyer belt because of the damage for appearance of getting stuck, pressure roller Bulk soil be tentatively crushed, and improves the adaptability to different soils, and closed promotion passes through device, and midway is avoided to fall Fruit, high-order discharge bin, entrucking is convenient and efficient, further improves working efficiency, applied widely, and collection excavates hack, broken piece, point From, screening, recycling multiple functions be integrated, can be suitably used for the harvest of various little particle root crops, and conveniently moving, promote Prospect is big, is the innovation on little particle root crop harvester tool, there is good social and economic benefit.
