The utility model content
The above-mentioned deficiency that the utility model exists to prior art; A kind of novel potato harvester is provided, on the topmost body that is characterised in that the tooth back two tilted-putted rotating cylinders is arranged, excavate through tooth potato and soil are entered in the rotating cylinder; Realize that through the bar shaped screen cloth on the barrel soil separates with potato; The rotating cylinder internal helical blades scrolls up potato, and makes potato through in the ascending separation bin that drains to the bottom of screen cloth, automatically the size of potato is carried out apportion; Practiced thrift the labour and reduced cost, efficient is expensive low easy for installation.
The purpose of the utility model is to realize through following technical scheme:
A kind of potato harvester comprises body, movable wheel, pull bar, tooth, transmission device, and said body has movable wheel, and said front part of a body is provided with tooth; Said body upper is provided with pull bar, and said body middle part is provided with separation bin, and said body both sides are provided with material taking mouth; Said separation bin upper angled is provided with rotating cylinder, and said rotating cylinder is pivotally attached on the body through axis, and said axis is provided with helical blade; The said helical blade outside is fixed with the rotating cylinder barrel, and said rotating cylinder barrel is provided with screen cloth, and said rotating cylinder front portion is provided with annulus; Said axis is provided with swing pinion near an end of tooth, and said tooth one end is downward-sloping, and the other end extends in the rotating cylinder through annulus; Said transmission device comprises turning cylinder, driven wheel, chain; Said turning cylinder is provided with driven wheel near rotating cylinder one end, and the other end is connected with hitching machinery, and said driven wheel is connected with said swing pinion through chain.
Said rotating cylinder is less near the screen cloth mesh of tooth one end, by preceding to after strengthen gradually.
Said screen cloth mesh is rectangle or circle.
Said rotating cylinder is provided with 1-5.
Said rotating cylinder is provided with 2.
The utility model beneficial effect: efficient is high, cost is low, easy for installation, labor savings, reduce cost.
Description of drawings
Fig. 1 is the described a kind of potato harvester structural representation of the utility model.
Among the figure:
1, body; 2, movable wheel; 3, pull bar; 4, tooth; 5, separation bin; 6, material taking mouth; 7, rotating cylinder; 8, axis; 9, helical blade; 10, rotating cylinder barrel; 11, annulus; 12, swing pinion; 13, screen cloth; 14, mesh; 15, power transmission shaft; 16, driven wheel; 17, chain.
Embodiment
According to accompanying drawing and embodiment the utility model is done further explain below.
As shown in Figure 1, at first make two rotating cylinders 7, the outer wall of rotating cylinder 7 is made upper screen cloth 13; Mesh 14 on the screen cloth 13 can adopt rectangle or circle hole shape; Narrower near the width of transmission device one side rectangle screen cloth 13, mesh 14 is less, by preceding to after strengthen gradually; Width is widened gradually, and the potato that makes different-diameter size from low to high, leaks down from rotating cylinder 7 in rotating cylinder 7 gradually; The middle part of rotating cylinder 7 is provided with axis 8, welding helical blade 9 on the axis 8, and helical blade 9 fixes with the screen cloth 13 of rotating cylinder 7 outer walls; Rotating cylinder 7 has the effect that stops near the just anterior mounting circular ring 11 of swing pinion 12 1 ends, prevents directly to fall on the ground from the potato that tooth 4 gets into; Install bearing in both sides, body 1 front and back, axis 8 is connected on the body 1 through what bearing can rotate, and axis 8 is installed swing pinion 12 near a side of transmission device; Body 1 middle part is divided into separation bin 5 according to the position of screen cloth mesh 14 different-diameters size; Its role is to the potato that tumbles from rotating cylinder 7, can fall different separation bin 5, realize the ascending classification of potato according to the size of mesh 14; At body 1 top and anterior welding upper connecting rod 3; Being connected with tractor provides tractive force, installs tooth 4 in body 1 underside of forward, its role is to when results, directly to insert in the soil potato is picked up.Install power transmission shaft 15 in body 1 front portion; One end of power transmission shaft 15 connects the output shaft of tow tractor; Revolving force is provided, the other end installing drive gear 16 of power transmission shaft 15, driven wheel 16 rotates through the swing pinion 12 on the chain 17 band axis 8; Thereby realize the rotation of helical blade 9 and rotating cylinder 7, realize the classification of potato.
At first pull bar 3 is linked to each other with the tractor rear portion during use; By tractor pulling pull bar 3 body 1 is moved forward, tractive force is provided, power transmission shaft 15 is connected on the output shaft at tractor rear portion provides rotary power for rotating cylinder 7 then; During use under the tractive force effect of tractor; Tooth 4 is firmly dug out potato and clod downwards from soil, a part of soil and soil block fall from the gap of tooth 4, and potato and part soil block enter into rotating cylinder 7 through tooth 4; Because there is annulus 11 rotating cylinder 7 ends; Prevented coming off of earth and potato, rotating cylinder 7 under the acting in conjunction of power transmission shaft 15, driven wheel 16, chain 17, swing pinion 12, the rotation that does not stop.Because the screen cloth 13 of long strip type is arranged on the rotating cylinder barrel 10, under having, the width of mesh 14 broadens the potato that effect is to fall different-diameter gradually to last; Because first screen cloth mesh 14 is less, soil block is spilt on first mesh 14 of rotating cylinder 7, directly falls on the ground; Potato is then along with helical blade 9 scrolls up; Superincumbent screen cloth 13 medium and small potatos fall in the less mesh 14 of mesh, fall 5 li of corresponding separation bins, and bigger potato falls in the bigger screen cloth 13 of mesh; Fall 5 li of corresponding separation bins; Realize the automatic clustering of potato, saved the artificial step of picking up and classifying, realized the automatic results of potato.
