Abstract
The utility model relates to an agricultural machine for yam harvesting. At present, most of the yam harvesters produced in China almost adopt the structures as the fixed digging shovel, the rod or the swing sorting screen, which cause the problems of the huge power consumption, the heavy loading of the screen surface, the incomplete cleaning, and the serious yam burying phenomenon. The utility model provides a yam harvester comprising digging components, wherein, a digging shovel is tightly fixed at the front end of the connecting rod base; a vibrating screen is arranged at the rear end of the connecting rod base; a front connecting rod and a back connecting rod separately hinge the two sides of the connecting rod base; a frame hinges the upper end of the front connecting rod; the middle of the back connecting rod is movably combined with the pin on the frame; two upper parts of the back connecting rods and the two ends of the connecting shaft are tightly fixed as a whole; an upper connecting rod is connected between the middle of the connecting shaft and the eccentric wheel on the power shaft. The utility model, adopting the structures of the connecting rod, the vibrating screen and the eccentric wheel, has the advantages of that can make the digging shovel and the vibrating screen vibrate, separate the earth from the yam in advance, alleviate the loading of the future work, save the oil, and improve the yam cleaning efficiency.
Description
Technical field
The utility model relates to a kind of farm machinery, especially gathers in the crops the machinery of potato class.
Background technology
At present, the potato harvester of domestic production is of a great variety, but type size no matter, its structure is basic identical, mostly adopts parts such as fixed digger blade, rod-type or swing type sorting screen.This structure causes power consumption big easily, and compass screen surface load is heavy, cleans not thoroughly, buries the serious problem of potato phenomenon.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of fuel oil of both having saved, and can improve the potato type harvesting machine that the potato class is cleaned effect again.
The technical solution of the utility model is: it comprises the excavation assembly, described excavation assembly is made up of digger blade, front rod, back link, connecting rod pedestal, vibratory sieve and last connecting rod, digger blade is fastened on connecting rod pedestal front end, vibratory sieve is equipped with in connecting rod pedestal rear end, connecting rod pedestal both sides are hinged with front rod and back link respectively, the front rod upper end is hinged with frame, the back link middle part cooperates with the bearing pin on the frame is movable, two back link tops and connecting axle two ends fasten as one, and are connected with connecting rod in the middle of the connecting axle and between the eccentric wheel on the line shaft.
The utility model adopts connecting rod, vibratory sieve and eccentric structure, makes digger blade and shaker vibration in the results process, carries out soil, potato separation in advance, alleviates the load of postorder work, has saved fuel oil, and simultaneously, the effect of cleaning the potato class obviously improves.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, the utility model is identical substantially with the prior art structure, is made up of hanger bracket 1, frame 2, line shaft 3, excavation assembly, oscillating riddle, road wheel, conveyer belt 7 and chaffcutter dish etc.The main contribution of prior art is to excavate assembly improves to some extent, it is made up of digger blade 10, front rod 5, back link 6, connecting rod pedestal 9, vibratory sieve 8 and last connecting rod 4.Digger blade 10 is fastened on connecting rod pedestal 9 front ends, vibratory sieve 8 is equipped with in connecting rod pedestal 9 rear ends, connecting rod pedestal 9 both sides are hinged with front rod 5 and back link 6 respectively, front rod 5 upper ends and frame 2 are hinged, back link 6 middle parts cooperate with the bearing pin on the frame 2 is movable, two back links, 6 tops and connecting axle two ends fasten as one, and last connecting rod 4 two ends eccentric wheel middle with connecting axle respectively and on the line shaft links to each other.The installation of other parts be connected with prior art basic identically, those of ordinary skills all can know, and no longer describe in detail.Its course of work is as follows: hanger bracket 1 is articulated on the tractor, starting tractor work, drive when tractor is advanced digger blade 10 with soil together with potato piece turn up.Simultaneously, on the eccentric wheel of the transmission of power of tractor to the line shaft 3, eccentric wheel drives back link 6 and digger blade 10, connecting rod pedestal 9 and vibratory sieves 8 by last connecting rod 4, is the axle center with the bearing pin that connects back link 6 middle parts, carries out reciprocating vibration.Like this, soil of just having excavated and potato piece carry out soil, potato separation and clods breaking in advance under the upper frequency vibration, and most of soil block sifts out from vibratory sieve 8, has alleviated the load of back operation, has saved the fuel oil of tractor, has improved cleaning efficiency simultaneously.Subsequently, remaining soil block and potato piece are sent on the conveyer belt 7, and soil block leaks earthward by the gap of conveyer belt 7.Last soil block in a small amount enters oscillating riddle together with the potato piece, further cleans and lay, thereby finishes the entire job flow process.
