Abstract

A potato digging harvester comprises an airframe, a speed-changing box, an actuating device, a rapping device, a digger, an apron belt and a ground wheel. The power driving shaft and the centerline of the machine are not at the same perpendicular line, which forms the relative polarization for the digging harvester and the tractor. Meanwhile the wheel group uses built-up construction of metal and rubber improving the service life of the products. The offset potato-digging harvester is suitable for the harvest of different ridge distance. When the ridge distance is large, the harvester can dig one ridge by one ridge. When the ridge distance is small, the harvester can dig two ridged by two ridges. The product has strong suitability and can be used to harvest potatoes with different planting methods.

Description

A kind of potato digging harvester

Technical field: the utility model relates to a kind of agricultural machinery, particularly a kind of results agricultural machinery.

Background technology: CN2753116Y, CN2704995Y, CN2312565Y etc. has all announced several small-sized potato harvester that structure is different, adopts tractor-drawn, has reached mechanical excavation and has replaced hand digging, the purpose of boosting productivity.But, anatomizing the back and find, the ridge of sowing is a key of decision technique scheme type apart from size, just needs according to different ridges apart from the sower of selecting different type of machines.And, influenced by traditional planting patterns in China rural area, the ridge of different regions sowing varies apart from size, if type is not inconsistent to cause and ploughs under situation under the soil again digging out the potato piece that comes, influences result of use.So technique scheme can not flexible Application in different planting patternss.

Goal of the invention: the utility model provides a kind of offset potato digging harvester, can adapt to the results of different ridge distances, is the single file operation, and tractor motive power output shaft is connected with the vibratory sieve power transmission shaft of digging harvester; Axially depart from the digging harvester center line, form departing from of reaping machine and tractor center line, promptly reaping machine is offset to tractor; Ridge can be from the digging over of the delegation of side delegation on ground when big, and ridge distance hour can one digging of two ridges, and the adaptation of product is strong.

Technical scheme: the potato digging harvester comprises parts such as body, gearbox, transmission device, vibrating device, digger blade, conveyer belt, land wheel.Wherein, body is made up of frame and power traction axle, and the power traction axle is a Cardan shaft, is connected with the vibratory sieve final drive shaft of vibrating device by gearbox.The power traction axle of excavator and the center line of body form the biasing of digging harvester and tractor relative position not on same vertical line.Vibrating device comprises the vibratory sieve driving wheel on the vibratory sieve final drive shaft that is connected by gearbox with axis of traction, by driven pulley and the driving belt tensioning adjustment wheel that band connects, and vibratory sieve holder sprocket wheel, directive wheel and be positioned at vibrating wheels below the vibratory sieve.Driving wheel, driven pulley, holder sprocket wheel, vibrating wheels, directive wheel adopt the metal-rubber combining structure, comprise axle sleeve, be enclosed within the rubber wheel of axle sleeve outside, in the both sides of rubber wheel the metal plate washer is arranged, rubber wheel radially is higher than the metal plate washer, run through fixing with screw, this structure can prolong the service life of wheel greatly.The number of teeth of driving wheel can be 8 to 14 teeth, the driven pulley of the different numbers of teeth of supporting use, holder sprocket wheel, vibrating wheels, directive wheel; By driving the driving wheel and the driven pulley of vibratory sieve, can change passing on of vibratory sieve.Two supporting plates about being positioned at body front end edge axis of traction and being symmetrically distributed, on open a plurality of holes, adjust the supporting plate height by connecting with different hole, can adjust excavating depth.The digger blade front end has fixed screw, and screw position is adjustable, by adjusting screw position, can adjust angle of penetration.

Its course of work is: the power take-off of tractor is connected with the vibratory sieve final drive shaft by Cardan shaft, through chang-over speed reducing box power is passed to the vibratory sieve driving wheel, by belt power is passed to driven pulley, the driving vibratory sieve rotates, the step vibrating wheels is arranged below vibratory sieve, make the vibration of chain-type sieve, holder sprocket wheel and directive wheel play respectively and prevent that chain from sinking and the effect of guiding.Tractor drives digging harvester and advances, digger blade excavates out with soil and potato together, be deposited into the vibratory sieve front portion, rotate and vibration through vibration, soil and potato are transmitted rearward, in transport process, vibrate through sieve, the soil sieve is gone, potato is placed in the excavator back, for manually picking up pack.

Beneficial effect: owing to adopt technique scheme, it is little, in light weight to the utlity model has volume; Compact conformation, flexible operation, the characteristics of parts long service life.Reliable and stable on the performance, the dig out rate height reveals potato rate height, and percentage of damage is low, can satisfy the agriculture requirement of potato harvest, can be fit to the results in Different Ways of Planting plot.Already compare the saving of labor with people and animals' masterpiece, shorten harvest time, suitable peasant household and collective use than large tracts of land results potato.The rural area small tractor is more, and power selects face big, supporting easily.This machine cost is lower, is suitable for peasant household and buys, and has promotion prospect.
