Description

A kind of auxiliary device for picking for pineapple picking

Technical field:

The utility model relates to a kind of fruit picking apparatus, specifically a kind of auxiliary device for picking for pineapple picking.

Background technique:

Pineapple is perennial fruit, and picking season property is very strong, while pineapple generally uses large area intensively to plant, mainframe Tool disengaging is inconvenient, therefore is not available for disposable Mechaniaed harvest in large area, and orchard worker can only be allowed according to the difference of maturity Pineapple is targetedly picked.At present both at home and abroad pineapple recovery operations manually based on, when orchard workers need long Between stoop labor.There are hangnail, pericarp with prickle on pineapple leaf, even if orchard worker's picked by hand has worn gloves, orchard worker also holds It is easily wounded by stabbing, increases the labor intensity of orchard worker, reduce picking efficiency.The considerations of this comprehensive several respect, it is therefore desirable to a kind of Structure is simple and convenient to operate, high-efficient pineapple picking mechanical arm indirect labor picks.

It is seldom for the development precedent of pineapple seed harvester at present according to inspection information." the one of existing Agricultural University Of South China Picking of the kind for pineapple picking mechanical arm end executes (201210431101.5) " it needs to be arranged and reverses motor, motor Setting is unfavorable for field long working.The pineapple seed harvester of some large sizes, may damage fruit, be not easy to the needle to pineapple Picking to property, the effect is unsatisfactory for picking.

Utility model content:

It is simple that the utility model is intended to provide a kind of structure, easy to operate, and the pineapple of economy and durability assists device for picking, with solution The problems such as certainly workpeople needs to bend over to work for a long time, and picked by hand is easy to be wounded by stabbing, and picking efficiency is low.

In order to realize above-mentioned purpose, the utility model uses a kind of following technical scheme: pineapple device for picking: mainly by spinach Trailing plants clamping device, height adjustment device, variation four-bar mechanism, motion controller and reversed winding mechanism composition.The clamping Device includes: gear pawl, whistle type drag hook, box, limited post；Motion controller includes: wire spool, rocking handle；Reversed coil winding machine Structure includes ratchet, pawl base, double wrap drum.Pineapple auxiliary device for picking drives whole device first to tighten, again by finer wire line Torsion achievees the purpose that pick pineapple.

Further, pineapple auxiliary device for picking drives reel by rocking handle, so that line is tauted, the steel wire tightened is drawn Whistle type drag hook of opening one's mouth achievees the purpose that hold pineapple tightly with moving gear pawl so that gear pawl closes up, while crescent moon fork supports pineapple Rhizome.This stage steel wire the other end due to pawl effect so that variation four-bar mechanism do not work.When reaching certain power After, pawl flicks, and under the action of making a variation four-bar mechanism, vertical bar torsion achievees the purpose that pick pineapple.After picking pineapple, Corresponding resetting apparatus makes device for picking reply work original state.

Further, using the mechanism of coiling and reversed coiling, so that uniaxially shaking rocking handle, that is, it may make clamping, turn round Disconnected pineapple successively carries out.

Further, the picking of pineapple auxiliary has height adjustment device, is adapted to pineapple picking different in size.

Compared with prior art, when the utility model solves artificial picking pineapple, time-consuming and laborious, low efficiency, orchard worker is curved The problems such as waist, injury, and pineapple auxiliary device for picking structure is simple, can pick pineapple by the simple operations of people, not need Motor driven separately is set, the adverse circumstances of field picking pineapple can be better adapted to.

Specific embodiment:

In order to facilitate the understanding of those skilled in the art, the utility model is made into one below with reference to the accompanying drawings and in conjunction with the embodiments The detailed description of step.

As shown in figures 1-4, it is a kind of for pineapple picking auxiliary device for picking, including for clamping pineapple clamping device, For adjusting the regulating device of height, the four-bar mechanism for pulling gear pawl, the middle controller for controlling movement and control Wire processed around to reversed winding mechanism.

Clamping device in the present embodiment includes a pair of of gear pawl 8, whistle type drag hook 13, jackshaft 14, limited post 15, divides Laminate 16, box 17；Its middle gear pawl 8 is mounted on box 17 by the fixed position of two jackshafts 14.Jackshaft 14 on the right Upper that a bearing is housed, bearing and gear pawl 8 cooperate.Meanwhile whistle type drag hook 13, whistle type drag hook 13 being housed on jackshaft 14 It is fixed together with gear pawl 8.There is a limited post 15 close to box rear end, which is fitted with torsional spring.Box Respectively there are one and the wide fluting of gear pawl 8 in sub 17 both ends, and cassette interior is driveed there are three hole, for connecting with lid.

Clamping device working principle: whistle type drag hook 13 under the pulling of steel wire by being rotated, to drive jackshaft 13 Rotation, axis drive right gear tire 8, and gear-linked is closed claw.When not working, due to the work of torsional spring and limited post 15 With making gear pawl 8 return to original state.

Height adjustment device in the present embodiment includes intermediate vertical bar 10, height adjustment device cover 6.Height adjustment device Cover 6 includes spring, positioning pin, floating junction, and there are also coniform holes on intermediate vertical bar.Height adjustment device to position by spring Pin card enters in coniform hole to realize positioning.

Middle controller in the present embodiment includes rocking handle 11, wire spool 18, motion controller box 12.Rocking handle 11, around Drum 18 and motion controller box 12 are connected as one by jackshaft, and there are two bearings on box for axis.

Reversed winding mechanism in the present embodiment includes pawl controller 2, repercussion winding mechanism outer box 1, double wrap wire wheel axis 19, ratchet 20.For dress there are two the reel of slot, the trend of line is opposite in reversed winding mechanism.

The working principle of reversed winding mechanism is most to be started by the control whole device movement of the power of ratchet and line due to pawl The effect of controller 2 is so that pawl blocks ratchet and is able to rotate ratchet 20 not, after current face gear pawl 8 is firmly grasped, due to line It tenses so that pawl jacks up upwards, ratchet is rotated, and reel in turn can be with take-up.

The pineapple auxiliary device for picking specific motion process be by finer wire line drive pineapple clamping device first tighten, Again vertical bar is reversed, achievees the purpose that pick pineapple.The pineapple assists device for picking to drive motion controller 12 by rocking handle 11, So that line is tauted, the steel wire tightened pulls whistle type drag hook 13 with moving gear pawl 8, so that gear pawl 8, which closes up, reaches holding spinach The purpose of trailing plants, while crescent moon fork 9 supports pineapple rhizome.This stage steel wire the other end due to pawl effect so that become Different four-bar mechanism 5 does not work.After the power for reaching certain, pawl is flicked, and under the action of four-bar mechanism 5, vertical bar 10 is reversed, Achieve the purpose that pick pineapple.After picking pineapple, corresponding reset spring 4 extends so that device for picking replys work original state.
