Abstract

The utility model relates to a pair of shears for fruits on high branches, particularly a pair of shears for picking fruits on high and strong branches, which relates to a tool for picking fruits by fruit growers. The utility model is mainly composed of a cam assembly, a branch clamping body, a pruning body, a knife body with a fixed handle, steel wires, etc. The length of the utility model can be increased by using a telescopic casing tube, the cam arranged on the end of the shears can be controlled to rotate by steel wires, and consequently, a clamp for clamping a fruit stalk and the pruning body can be driven to actuate, and the purpose that fruits on the upper part of fruit trees which is hard to pick by hands can be picked by standing on the ground. The utility model has the advantages of simple structure, convenient operation, flexible operation, low cost, etc. The utility model is not only suitable for picking fruits on high branches but also suitable for cutting plants under the water for a certain depth.

Description

Shears for fruits on high branches

The utility model relates to a kind of instrument of orchard worker's fruit-picking, refers in particular to a kind of scissors of plucking fruit on the high bough.

The orchard worker generally is to adopt special-purpose fruit to cut to pluck when picking the fruit in orchard, still, just have to pluck by the help of staircase for the fruit on the upper strata that is grown in fruit tree, and studying carefully its drawback has three:

1, must two people cooperate and can carry out in the process of fruit-picking: lift staircase as two people, a people buttresses staircase in the harvesting process, and a people plucks;

2, picking efficiency is low, and the orchard worker can only pluck in the scope of activities at ladder top, and plucks lot and must move staircase one time;

3, pluck process hazard, the orchard worker should stand firm firmly at the top of staircase, must climb to a higher point in big as far as possible scope again and climb down the ground fruit-picking.

Its drawback in sum so there is improved necessity very much.

I am to overcome above-mentioned weak point of the prior art order of the present utility model, and provide a kind of orchard worker can be in terrestrial operation, and scissors can be at the Shears for fruits on high branches of the out of reach eminence action of staff.

The utility model is achieved by the following scheme: use telescope to increase length, cam by steel wire control scissors termination rotates, thereby drive the anchor clamps and the beta pruning body action of clamping fruit handle, reach and stand in the purpose that the out of reach fruit of fruit tree top staff also can be plucked in ground.

The utlity model has advantages such as simple in structure, that operation is nimble, cheap, be suitable for plucking the fruit on the branches of tall trees, also adapt to the clip plant of certain depth under water.

Below in conjunction with accompanying drawing the utility model is further specified:

Accompanying drawing 1 is the utility model front view

Accompanying drawing 3 is cam pack 5 partial enlarged drawings

Accompanying drawing 4 is cam 51 stereograms

Accompanying drawing 5 is connector 4 stereograms

Accompanying drawing 6 is the utility model A-A cutaway view

Accompanying drawing 7 is folder branch body 2 front views

See accompanying drawing 1-5, the utility model is by fixed handle cutter hub 1, folder branch body 2, beta pruning body 3, cam pack 5, steel wire 6, sleeve pipe 9, bearing pin 10, pulley 11, support 12, holding rod 13, handle 14 is formed, fixed handle cutter hub 1, folder branch body 2, beta pruning body 3 is connected as a single entity by bearing pin, the other end at fixed handle cutter hub 1 is connected with sleeve pipe 9 by bearing pin 10, stage casing at fixed handle cutter hub 1, be with the cam pack 5 of two same shapes on the garden boss on its both sides, cam pack 5 is by cam 51, connector 4, spring 15 is formed, on cam 51, symmetry has several holes 7, and the tenon on the connector 4 is inserted in respectively in two holes on the cam 51, two cams 51 are connected as a single entity, between two

cams

51,15 1 on spring is fixed on the cam 51, and the other end is fixed on the fixed handle cutter hub 1.Towards one side of outside, be fixed with a boss 8 at two cams 51, its boss 8 is inserted in respectively in the groove of folder branch body 2 and beta pruning body 3 one ends.One of telescope 9 links to each other with holding rod 13 by bearing pin 10, and support 12 is fixed on the holding rod 13, and an end of handle 14 is connected on the holding rod 13 by rotating shaft.Steel wire 6 one ends are fixed on the connector 4, and the other end is drawn between two cams 51, around bearing pin 10, pass sleeve pipe 9, holding rod 13 is through being fixed on the pulley 11 in the holding rod 13, pass the hole from holding rod 13, and, be fixed on the handle 14 through the hole on the support 12.

The angle that the angle that fixed handle cutter hub 1 and folder branch body 2 are in original state is in original state less than fixed handle cutter hub 1 and beta pruning body 3.

See accompanying drawing 6, the cross section of fixed handle cutter hub 1 blade is the L type, and adhesive tape 101 is embedded in the groove at middle part, in the groove on the folder branch body 2 of no sword, is embedded with the adhesive tape 201 of protruding folder branch body 2 planes.

See accompanying drawing 7, press from both sides branch body 2 by a folder branch body handle 21, axle 22, spring 23 compositions, the folder branch body handle 21 that is divided into two sections is linked as an integral body by rotating axle 22, and the two ends of spring 23 are separately fixed on the folder branch body handle 21 that is divided into two sections.

When using the utility model, regulate the length between sleeve pipe 9 and the holding rod 13, make and just in time aim at the fruit branch position for the treatment of fruit-picking between fixed handle cutter hub 1 and the folder branch body 2, be used to pull handle 14, when handle 14 moves down, the steel wire 6 same moved further on it are fixed in drive, because of the other end that passes hole on the support 12 and the steel wire 6 in holding rod 13 and the sleeve pipe 9 is fixed on the connector 4 in the cam pack 5, by connector 4, overcome the elastic force that is connected the spring 15 on cam 51 and the fixed handle cutter hub 1, make the boss of cam 51 that abuts in fixed handle cutter hub 1 both sides rotate around fixed handle cutter hub 1 middle part, and because the boss 8 on the cam 51 is inserted in the groove of the shank that presss from both sides branch body 2 and beta pruning body 3, so drive folder branch body 2 and beta pruning body 3 around being connected and fixed handle cutter hub 1, folder branch body 2, the bearing pin of beta pruning body 3 rotates, because of the angle between fixed handle cutter hub 1 and the folder branch body 2 less than the angle between fixed handle cutter hub 1 and the beta pruning body 3, so folder branch body 2 is in rotation process, adhesive tape 201 on the folder branch body 2 at first touches the adhesive tape 101 on the fixed handle cutter hub 1, and the fruit branch of fruit is clipped in wherein, when being rotated further folder branch body 2, position-limiting action because of fixed handle cutter hub 1, make an end that presss from both sides trough of belt on the branch body 2 restrain the elastic force of eye spring 23, rotate around axle 22.Meanwhile, beta pruning body 3 rotates synchronously, and its blade touches the blade of fixed handle cutter hub 1, and fruit fruit branch to be plucked is cut off, and takes.

In case the fruit fruit branch is cut off, is taken, release handle 14, under the tension of spring 15, cam 51 opposite spins, make fixed handle cutter hub 1, folder branch body 2, beta pruning body 3 recovers initial state, and is ready for plucking next fruit, meanwhile, under the effect of spring 23, the folder branch body handle 21 of an angle of deflection rotates around axle 22, makes folder branch body 2 restore to the original state.
