Abstract

A fruit picking device comprises a supporting rod, a pair of scissors and a storage net. The supporting rod is formed by connecting a plurality of crossed short arms, each crossed short arm comprises a first connecting piece and a second connecting piece which are crossed, and the end of each first connecting piece and the end of the corresponding second connecting piece are movably connected with the end of the second connecting pipe and the end of the first connecting piece of the adjacent crossed short arm through movable hinge pins. The two ends of handles of the scissors are movably connected with the end of the first connecting piece and the end of the second connecting piece of one crossed short arm at the top end of the telescopic supporting rod respectively, and the pair of scissors at the upper end of the supporting rod can be driven to be opened and closed by opening and closing the two connecting pieces of the crossed short arm at the lowermost end of the supporting rod. According to the fruit picking device, the multiple crossed short arms composed of the mutually crossed connecting pieces are connected to form the supporting rod of the fruit picking device, the pair of scissors at the upper end can be driven to be opened and closed by opening and closing the crossed short arm at the bottommost end so that pedicels can be shorn, and meanwhile shorn fruits are collected by the storage net below the scissors to prevent the fruits from directly falling off.

Description

Fruit picking apparatus

Technical field

Background technology

At present, in the time plucking the fruit such as apple, pears, persimmon, need to climb tree or by ladder, the amount of labour is large, dangerous high, inefficiency.

In prior art, CN202232192U discloses a kind of flexible picking rod, comprise a scalable hollow mobile jib, mobile jib top connects a hollow pole, on pole, hang a string bag and above the string bag, be provided with a scissors, scissors one end handle is fixed on described pole, scissors other end handle connects a steel wire, steel wire is through mobile jib and pole inside, cut off the base of fruit of fruit by establish folding that a rotating shaft pulls steel wire to realize scissors in mobile jib bottom, fruit just falls into the string bag, realizes the fruit picking of long distance.The disadvantage of this instrument is that the shearing force that pulls the mode of scissors closure to produce by steel wire is little, is difficult to cut off hard fruit tree.

Summary of the invention

Embodiment

Structure of the present invention is described further by embodiment below in conjunction with accompanying drawing.

As shown in Figure 1,

A kind of fruit picking apparatus, comprising:

Telescopic pole 11, scissors 12 and storage net 13.

Pole 11 comprises the mobilizable intersection galianconism 21 of more piece.Mobilizable intersection galianconism 21 is made up of the first brace 31 and second brace 32 of two elongate in shape.

The middle part of the first brace 31 and two cephalic pars are provided with laterally projecting bearing

34,33 at homonymy, bearing

34,33 upper parts or be all provided with screw thread, the middle part of the second brace 32 and two cephalic pars are provided with hole 36,35(is shown in Fig. 4); After bearing pin 33 extends through the hole 36 at middle part by be tightened on nut on screw thread by the first brace 31 and the second brace 32 be movably connected form a joint intersect galianconism 21, the first braces 31 and the second brace 32 can free opening and closing.The end of the first brace 31 and the second brace 32 intersects the second brace of galianconism and the end of the first brace with adjacent (upper and lower two ends identical) joint respectively and is movably connected by active pin shaft 34, jointly forms pole 11 structures.

Scissors 12, its handle of a knife two ends are flexibly connected respectively the first brace 31 of telescopic support struts 11 top one joint intersection galianconism 21 and the end of the second brace 32 by active pin shaft and hole, and two braces of opening and closing pole 11 intersection galianconism bottom can drive the folding of pole 11 upper end scissors 12.The mode of this flexible connection has minimum resistance, can be directly by the opening and closing power of pole 11 bottoms almost without the scissors that is delivered to upper end 12 of impairment, coordinate the aduncate radian of blade of scissors 12 and the blade lengths of scissors 12 to be less than the length (lever principle) of handle of a knife simultaneously, make scissors 12 there is great shearing force, remove storage net 12 also can be used as branch pruning scissors use.

Storage net 13, the dictyosome 22 that comprises screen frame 23 and supported by screen frame 23.

The joint number of intersection galianconism 21 can increase and decrease arbitrarily, to control the maximum elongation length of telescopic support struts 11.

As shown in Figure 2, pole 11 remains on a plane after being connected by the mobilizable intersection galianconism 21 of more piece, and the screen frame 23 of storage net 13 is fixing removably with scissors 12 handle of a knife middle part active pin shafts.Fruit picking apparatus after storage net 13 is packed up can be realized the function of pruning fruit tree scissors.

The storage pocket actinal surface of net 13 and the blade of scissors 12 are acute angle.

As shown in Figure 3: the middle part of the first brace 31 and two cephalic pars are provided with laterally projecting bearing

34,33 at homonymy, bearing

34,33 upper parts or be all provided with screw thread.

As shown in Figure 4, the middle part of the second brace 32 and two cephalic pars are provided with hole 36,35.Coordinate the

bearing pin

34,33 in Fig. 3 and screw nut can, by the first brace 31 and the second brace 32 middle part interconnections, be connected with adjacent the first brace and the second brace that intersects galianconism 21 simultaneously.

Although present invention is described with reference to the embodiment of showing in accompanying drawing, should be appreciated that and do not deviating under the spirit and scope and background of the present invention's instruction, fruit picking apparatus of the present invention can have many versions.Art technology those of ordinary skill also has different modes to change the parameter in disclosed embodiment of this invention by recognizing, for example intersect connected mode, size, shape or the element of galianconism or the type of material, all fall in the spirit and scope of the present invention and claim.
