For the convenient manufacture, the curved surface is in a circular arc shape. The device of the invention not only keeps high picking rate, but also effectively reduces the stem carrying rate of fruit pods and the rates of seedling breaking and root breaking, thus the harvest quality of a semi-feeding peanut combine harvester can be significantly improved.
Description
Technical field
The present invention relates to a kind of picker, especially a kind of semi-feeding device for harvesting peanut and picking fruit belongs to agricultural machinery technological field.
Background technology
Understand according to the applicant, peanut combine mainly contains full feeding and partly feeds two kinds of forms at present.The full feed type peanut combine exists the climing winding of seedling, breakage rate height, fruit seedling to separate shortcomings such as unclean, that power consumption is big, and the semi-feeding type peanut combine can overcome above shortcoming, semi-feeding type peanut combining mode is not to the climing pulverizing of seedling, destruction simultaneously, and the seedling after the results is climing still can be as the high-quality feed of animal.In recent years, the semi-feeding type peanut combine has become the development trend of peanut combine.
Existing semi-feeding type peanut combine picker as shown in Figure 1, main two rollers 2, the difference phase assembling form of adopting, the board-type that is fixed on the roller is plucked fruit blade 5 along with roller is made high speed rotating (referring to " agricultural research " first phase in 2008 98 pages of " design of horizontal pair of roller peanut picker " literary compositions, especially Fig. 5 of this article), the fruit seedling that passes through is brushed to take off pluck fruit.In fact this picker takes off formula by brush and plucks fruit, its pick up rate height, but many with fruit in season pod band handle rate height, the disconnected branch of seedling breaking, influence results quality.And fruit pod band handle rate height cause must the more manpower of cost manual extract on the fruit pod with carpopodium, the disconnected branch of seedling breaking has strengthened separating of results later stage peanut fruit and seedling branch at most.Above problem has become the technical bottleneck of semi-feeding type peanut combine.
Summary of the invention
The objective of the invention is to: at the problem of above-mentioned prior art existence, a kind of not only pick up rate height is proposed, can effectively reduce fruit pod band handle rate and the seedling breaking semi-feeding device for harvesting peanut and picking fruit of rate of being completely cured, thereby significantly improve the results quality of semi-feeding type peanut combine.
In order to reach above purpose, the applicant is through the long period field trial, recognize gradually: the pick up rate height no doubt give the credit to board-type pluck the fruit blade brush take off effect, but simultaneously (referring to Fig. 5) causes and plucks fruit consequence pod 7 band handle rate height, the many seeds of trouble of the disconnected branch of seedling breaking also are that board-type is plucked the fruit blade construction.Because taking off, the brush of this structure in the peanut picking process, not only has the power of pullling, also has tangible dissection simultaneously, the result is under carpopodium 8 and situation that fruit pod 7 does not separate, not only easily fruit pod 7 is cut off from rhizome together with carpopodium 8, simultaneously seedling, branch 9 are cut off by force and fruit pod 7 band handles are come off.
On this understanding basis, the present invention proposes the technical scheme as second feeding peanut picker: this device constitutes by the poor at interval a pair of roller of plucking the fruit blade that distributes mutually radially is housed, and the described fruit blade of plucking is towards deviating from the crooked gradually continuous curve surface of roller direction of rotation.Make for convenient, described curved surface is a circular arc camber.
Of the present invention further improving is that the bending direction of described curved surface outer most edge tangentially overlaps with the envelope of described outer most edge circle.
During work, it is to exist the brush of rigidity shear action to take off that arc plucks that the fruit blade no longer resembles the board-type the active force of peanut pod, and becomes the beating to the peanut pod, so essential change has been given birth in machine for picking fruits haircut, play similar craft and get rid of dozen action effect of plucking fruit, softization of active force.Facts have proved, not only kept high pick up rate, and effectively reduce fruit pod band handle rate and the seedling breaking rate of being completely cured, thereby can significantly improve the results quality of semi-feeding type peanut combine.

Embodiment
Embodiment one
The semi-feeding device for harvesting peanut and picking fruit of present embodiment is made of a pair of roller 3 as shown in Figure 3, and two rollers radially are equipped with the really blade 5 of plucking of poor at interval distribution mutually, and promptly the fruit blade 5 of plucking of two rollers staggers mutually.Roller 3 two end supports are on roller axle 1, outer circle diameter is to extending vanes fixed seat 2 spaced apart, be equipped with by set bolt 4 on each vanes fixed seat and pluck fruit blade 5, pluck fruit blade 5 and be towards deviating from the crooked gradually circular arc camber of roller 3 direction of rotation, two ends have chamfering (referring to Fig. 2).
During work, arc is plucked the fruit blade peanut pod is produced the beating effect, and no longer is that brush takes off effect, has therefore avoided shear action.And because that arc is plucked the fruit blade is crooked gradually towards deviating from the roller direction of rotation, so linear velocity gets over general goal, more towards rear-inclined, pats softization of active force thereby make, and more approaching craft is got rid of and beaten the action effect of plucking fruit.As a result, be applied on the semi-feeding type peanut combine after, with the board-type of prior art pluck the fruit blade compare, not only kept high pick up rate, and fruit pod band handle rate has been reduced more than 20%, and the seedling breaking rate of being completely cured has then reduced more than 80%, and the results quality significantly improves.
Embodiment two
Present embodiment partly feed peanut picker as shown in Figure 3, basic structure is identical with embodiment one, difference is: roller 3 outer circle diameters to extended vanes fixed seat 2 towards deviating from roller 3 direction of rotation, be advisable at 30 ± 5 ° with angle radially, the bending direction that circular arc is plucked fruit blade 5 outer most edge tangentially overlaps with the envelope circle that circular arc is plucked fruit blade 5 outer most edge.Like this, when the seedling branch of plucking fruit blade 5 and branch shape, rhizome, when carpopodium contact, its panting action only can make it that deformation takes place, and is unlikely to make rhizome, carpopodium to be cut off, and has only when contacting with the fruit pod, just can produce than tangible impact force, and it " is taken ".
Facts have proved that after present embodiment was applied to and improves on the semi-feeding type peanut combine, beneficial effect was better than embodiment one, has broken through the technical bottleneck of semi-feeding type peanut combine.
In addition to the implementation, the present invention can also have other embodiments.For example, the continuous curve surface of plucking the fruit blade also can be gradually open surface, Archimedian screw curved surface etc. except circular arc camber; And for example, the vanes fixed seat is not limited to shown in Figure 2, and is parallel with the roller axis, and also shape in the shape of a spiral along the distortion of roller axis, thereby makes the continuous curve surface of plucking the fruit blade become three-dimensional space curved surface, thereby realizes along drum shaft being convenient to the fruit pod and concentrating to patting in proper order.These also are feasible technical schemes through evidence.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
