The pitaya picking device has the advantages that the four clamping jaws are arranged on pitaya in a sleeving mode by pushing the push rod, the blade is used for cutting the connecting portion of the pitaya and branches, so that the pitaya is separated out, the picked pitaya abuts against the baffle, and workers can be prevented from being stabbed by burrs on the branches.

Description

TECHNICAL FIELD

[0001] The utility model mainly relates to fruit picking technical field, concretely a kind of mechanical arm for pitaya picking. BACKGROUND

[0002] Current pitaya picking is mostly picked by hand, when picking, worker holds pitaya with one hand, and holds cutting knife or scissors with the other hand to separate pitaya from branch, when picking, burr on pitaya branch is easy to prick worker, and the picking method is also relatively low in efficiency. CONTENT OF UTILITY MODEL

[0003] The utility model for achieving the above-mentioned purpose by following technical scheme realizes:

[0004] A kind of mechanical arm for pitaya picking, including sleeve, the push rod is arranged in the sleeve inside sliding, the push rod end is fixedly arranged connection plate, the connection plate top is arrayed hinged connecting rod, every the connecting rod other end is hinged clamping jaw.

[0005] The clamping jaw is arranged in arc, the clamping jaw outer ring is close to bottom and is hinged with the end of sleeve, the clamping jaw inner ring is close to top and is fixedly arranged blade, the clamping jaw inner ring is close to bottom and is fixedly arranged baffle.

[0006] The first baffle ring is fixedly arranged in the sleeve inner wall, the second baffle ring is fixedly arranged in the push rod outer ring, spring is set between the push rod outer ring between first baffle ring, second baffle ring.

[0007] Compared with prior art, the beneficial effects of the utility model are:

[0008] The utility model has the advantages of simple structure, easy to install and use, four clamping jaws are sleeved on pitaya by pushing push rod, blade is used to cut the connecting part of pitaya and branch, so as to separate pitaya, the picked pitaya abuts against baffle, can avoid burr on branch to prick worker, and picking efficiency is high, arc-shaped clamping jaw is used, pitaya of different size can be picked.

[0013] The utility model will be further explained in connection with the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and not to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various modifications or modifications to the utility model, and these equivalent forms also fall within the scope defined by the present application.

[0014] In connection with the drawings, a mechanical arm for pitaya picking, including sleeve 1, the push rod 2 is arranged in the sleeve 1 inside sliding, the push rod 2 end fixedly arranged connecting plate 3, the push rod 2 another end fixedly arranged handle, the connecting plate 3 top array hinge connecting rod 4, every connecting rod 4 another end is hinged to clamp jaw 5.

[0015] The clamp jaw 5 is arranged in arc shape, the clamp jaw 5 outer circle is hinged to the end of sleeve 1 near the bottom, the blade 6 is fixedly arranged in the inner circle of clamp jaw 5 near the top, the root is cut off by this structural design, the baffle 7 is fixedly arranged in the inner circle of clamp jaw 5 near the bottom.

[0016] Its characterized in that: the first baffle ring is fixedly arranged in the inner wall of sleeve 1, the second baffle ring is fixedly arranged in the outer circle of push rod 2, the spring is arranged in the outer circle of push rod 2 between the first baffle ring and the second baffle ring, four clamp jaws 5 are driven to open and close by this structural design.

[0017] The four clamp jaws 5 are in closed state under the action of spring when the device is in non-use state, the four clamp jaws 5 are opened by pushing the push rod 2, the pitaya to be picked is sleeved, the push rod 2 is loosened to make the four clamp jaws 5 close, and the blade 6 cuts the connection between the pitaya and the branch, the cut pitaya is left in the four clamp jaws 5 and abuts against the baffle 7, which can avoid the pitaya from falling to the ground during cutting, the pitaya is taken out from the clamp jaw 5, the next pitaya picking is carried out, the worker can be prevented from being pricked by burrs on the branch, the picking efficiency is high, and the picking quality of pitaya can be guaranteed.

[0018] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the scope of the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify or replace some technical features of the technical solutions recorded in the foregoing embodiments; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
