Description

Peanut picking four seperators

The utility model belongs to agricultural machinery, specifically a kind of farm machinery that are used for peanut picking.

The peasant is manually to pluck fruit when the results peanut for a long time, and labour intensity is big, and efficient is low.The patent No. is that 95226734.9 utility model patent " peanut picking separator " discloses a kind of farm machinery that peanut picking is cleaned usefulness that are used for, it by frame, cylinder, cover, blower fan, air outlet, conveying stir cage, concave grate and running gear, transmission mechanism is formed, with the supporting use of tricycle, the tricycle power-take-off pulley links to each other with the cleaning fan belt pulley through gear-box, 3～5 groups of rib formula screw type tooth groups are arranged in the cylinder, and concave grate etc. also is equipped with in the cylinder lower end.This Realization by Machine the automation peanut picking, improved production efficiency, but its structural design is unreasonable, mainly show following several respects: 1. Flow of Goods and Materials is not smooth in the cylinder, easily stops up, and goes out climing not smooth; 2. the air quantity of blower fan is unadjustable, and adaptability is bad; 3. fan airflow blows the wet soil of not going out and is difficult to separate with peanut again; 4. cylinder is an all welded construction, inconvenient maintenance.

The purpose of this utility model just provides a kind of improved peanut picking separation machinery, overcomes the shortcoming of existing type, peanut, climing, leaf, soil and fruitlet girl can be separated well, further improves the efficient and the performance of plucking fruit.

It by frame, cylinder, shell of top cover, concave grate, blower fan, stir cage, feeding hopper, vine outlet and transmission system and form, it is characterized in that said cylinder is a garden columnar shaft stream roller, constitute by drum shaft, spoke dish, ratch, bow tooth, ratch is installed in parallel in the cylinder, bow tooth on the ratch becomes helical arrangement, the bow tooth not only arches to the direction of rotation bending, and to the crooked angle of Flow of Goods and Materials direction; Said concave grate also is equipped with row's bow tooth, and the bow tooth is also to the bending of Flow of Goods and Materials direction; Be welded with spiral guide plate on the said shell of top cover; Said vine outlet is arranged on the below of one on cylinder.

There is air-flow plate at air inlet place at blower fan, when air quantity is big when light peanut is blown out, air-flow plate is blocked some air inlets, is as the criterion peanut leaf and impurity being blown out and peanut do not blown out.Stir the cage blade and stir the bottom of cage shell 14 and the gap of both sides is 4～6 millimeters.

Be drilled with many eyelets in the cage shell bottom of stirring of stirring cage, in stirring the defeated fruit of cage process, blower fan blows the grogs and the fruitlet girl that do not go out and leaks down from eyelet, once separates again, guarantees four separating properties that this machine is good.

Being key connecting between cylinder spoke dish and the drum shaft, is Bolt Connection between bow tooth and ratch, ratch and the spoke dish.

Owing to adopted said structure, so this machine is compared with existing type and is had the following advantages: 1. be equipped with on bow tooth, the shell of top cover on the bending direction of the arrangement of bow tooth, ratch in the cylinder, bow tooth, the concave grate and be welded with spiral guide plate, these structures guarantee that this machine has higher production efficiency and the good fruit performance of plucking, vine outlet is below one on cylinder simultaneously, climingly dish out from oblique below, guarantee out climing smooth, Flow of Goods and Materials is fast, cylinder is difficult for stopping up, per hour 2～3 mu of productivity ratio, pick up rate is greater than 98%, and percentage of damage is less than 1%; 2. blower fan two ends air inlet has air-flow plate, regulates the air quantity size; 3. stir cage shell bottom and be drilled with eyelet, blower fan blows the grogs and the fruitlet girl that do not go out and leaks down from eyelet, and existing other types do not have this separating property again.4. bow roller gear and ratch, ratch and spoke dish adopt Bolt Connection, are convenient to repair and replacement behind the bow odontotripsis, are that all welded construction is good than existing type cylinder, are unlikely to bend that odontotripsis or indivedual part damage and whole cylinder is scrapped or be difficult to repairing.So this machine novel structure, uniqueness, the efficient height, performance is good, uses convenience easy to maintenance, is a kind of peanut picking facility more better than existing type.

Be described in detail the utility model below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the supporting use schematic side view of the utility model and tricycle;

Fig. 3 is the roller frame schematic diagram;

Fig. 4 is cylinder and shell of top cover lateral plan;

Fig. 5 launches schematic diagram for cylinder;

Fig. 6 launches schematic diagram for shell of top cover.

Referring to Fig. 1, Fig. 2, this machine by frame 1, shell of top cover 2, cylinder 3, concave grate 21, blower fan 25, stir cage 13, feeding hopper 24, vine outlet 16 and transmission system and form; It and tricycle 18 supporting uses, as shown in Figure 2, be fixed in tricycle underframe rear end, the passive belt wheel 11 of blower fan directly connects by V-belt and tricycle engine output pulley 26, can use, also much convenient and easy when more supporting through the gearbox transmission than existing type and tricycle.Blower fan driving pulley 10, the passive belt wheel 11 of blower fan, cylinder driving pulley 7, the passive belt wheel 8 of cylinder, stir the transmission system that cage belt wheel 12, V-belt 9 have constituted this machine.

Fig. 3, Fig. 4, Fig. 5 have expressed the structure of cylinder 3.This cylinder 3 is a garden columnar shaft stream roller, constitute by drum shaft 27, cylinder bracing ring 28, spoke dish 6, tooth plate 29, ratch 5, bow tooth 4, ratch 5 is installed in parallel on the cylinder, 4 one-tenth helical arrangement of bow tooth on the ratch 5, Fig. 5 arranges for bow roller gear and launches schematic diagram, in Fig. 5, the fine line of inclination is helix, and the intersection point of helix and ratch 5 is bow tooth mounting points; Being key connecting between cylinder spoke dish 5 and the drum shaft 27, is Bolt Connection between bow tooth 4 and ratch 5, ratch 5 and the spoke dish 6.Bow tooth 4 not only arches to the direction of rotation bending, and to the crooked angle of Flow of Goods and Materials direction, as shown in Figure 3, Figure 4.Concave grate 21 below the cylinder 3 also is equipped with row's concave grate bow tooth 22, also to the bending of Flow of Goods and Materials direction.Be welded with spiral guide plate 30 on the shell of top cover 2 of cylinder top, as shown in Figure 6; Also be provided with gap adjustment bolt 15 between cylinder 3 and the concave grate 21.Said vine outlet 16 is arranged on the below of 3 one on cylinder.

During the work of this machine, will be with the fruit peanut vine to send charging aperture 23, under the rotation of cylinder 3 by feeding hopper 24, by bow tooth 4 peanut vine is led in the machine chamber, and, under the currying of the guide plate 30 of bow roller gear 4, concave grate 21 and concave grate bow tooth 22, pincer attack, rubbing, peanut is taken with cylinder rotation.Pluck clean fruit climing with the cylinder rotating flow to vine outlet 16, under centrifugal action, outside the machine of being dished out.Really, fallen leaves and light small impurities fall by the hole of concave grate, in the moment of falling, fan airflow separates it, is blown out outside the machine by air outlet 20.The air quantity size is blocked how much regulating of blower fan 25 air inlets by air-flow plate 19, is as the criterion peanut leaf and impurity being blown out and peanut do not blown out.Peanut and heavier grogs fall into and stir cage shell 14, under the effect of stirring cage 13, clean fruit are transported to a fruit outlet 17, fall into and connect fruit bag 31; Grogs and fruitlet girl really once separate with soil by leaking down in the eyelet that stirs on the cage shell 14 again.So far, peanut, climing, leaf, soil and fruitlet girl separate well, have guaranteed four good separating properties.Stir the cage blade and stir the bottom of cage shell 14 and the gap of both sides is 4～6 millimeters, guarantee that stirring cage goes slick, defeated fruit smoothly, not broken again fruit is assembled also more convenient.
