Description
Technical field
The invention belongs to the present invention relates to the tools of the tool of agricultural and sideline products harvest application more particularly to fruit picking
Class, in particular to a kind of portable variable-angle shears for picking fruit.
Background technique
China is large agricultural country, and fruit growing is the important component of agricultural, and the fruit tree output value is in China agriculture (plantation)
It is only second to grain, dish occupies third position.At the same time, the fruit growing comprehensive mechanization level in China is very low, therefore picking fruit efficiency
Very low, manpower and material resources consumption is big.
And in recent years, rural area youth strong labour power outflow is serious, the mainly old, weak, sick, residual of stay-at-home rural area, women and youngster
It is virgin.And picking fruit, at present mainly by fruit picker picked by hand, fruit picking apparatus is short in addition, therefore labor intensity is very in a short time
Greatly, danger coefficient is big, requires height to the physical efficiency of picking personnel, therefore a very big contradiction occur, does not consider social policy
It is adjusted with the stream of people, current relatively effective solution is exactly to improve picking condition, improves device for picking, is reduced to picking personnel's body
The requirement of energy.And the picking to certain relatively high fruit, traditional fruit picker seem helpless.
Summary of the invention
Technical problem solved by the present invention is in order to overcome the deficiencies of the prior art, the present invention designs a kind of novel fruit picking
It cuts, it had not only been able to achieve the picking to eminence fruit, but also the safety of energy support personnel, while also to have certain picking efficiency and adopt
Pluck quality.And under the national policy as defined in " People's Republic of China's mechanization of agriculture promotion law " is encouraged, agricultural will be into one
Step develops towards mechanization direction.With the high speed development of China's manufacturing industry and substantially mentioning for mechanization of agriculture popularity
Height, mechanical picking replaces handwork to be inevitable development trend, therefore its market prospects is also very good.
The technical scheme is that a kind of portable variable-angle shears for picking fruit, including scissors bit, support adjust compound rod
Part and handle, and scissors bit, support adjust combined member bar and handle is sequentially connected；

It is glued at the top of thin mobile jib and fixes.
Scissors bit and handle: being protruded on the bolt of lower sword limiting slot in scissors head part is to have a lead, and lead successively leads to
It crosses: inside the thin mobile jib in arbor adapter, support adjusting combined member bar component in scissors head part, supporting adjusting combined member bar
Inside thick mobile jib in component, fastened on the cross bar inside handle rotating member that is finally wound in handle component, by adjusting manually
Save circle number of the wire wound on cross bar, the adjustable wire length used.
Support adjusts combined member bar and handle: support adjusts the thick mobile jib bottom in combined member bar component and is inserted into handle component
In handle fixing piece upper circular groove in, be glued fix.
Present apparatus working principle is described for plucking peach below:
The default conditions of device:
1. the limit spring in limiting slot is in pre-compressed state, spring has restoring force.
2. the restoring force of spring makes the bolt in limiting slot be in maximum position end.Since the bolt and upper sword are affixed, because
Sword is also at maximum position end on this.Upper sword and lower sword are discrete state at this time.
3. thin mobile jib and thick mobile jib are connected by positioning pin.
4. fine tuning pole and coarse adjustment pole are connected by positioning pin.
5. lead is in tie-down state, the restoring force of spring acts on bolt, ties up to the lead on bolt by pulling force, lead
The handle rotating member of the other end is in maximum deployed position.
The preparation state of device:
1. unclamping the lead tied up on the cross bar inside handle rotating member.
2. extracting the positioning pin between thin mobile jib and thick mobile jib, thin mobile jib is slided to suitable position, is aligned on thin mobile jib
Aperture on aperture and thick mobile jib, being inserted into positioning pin keeps thin mobile jib and thick mobile jib affixed.
3. extracting the positioning pin between fine tuning pole and coarse adjustment pole, sliding fine tuning pole to suitable position is aligned fine tuning
The aperture on aperture and coarse adjustment pole on pole, being inserted into positioning pin keeps fine tuning pole and coarse adjustment pole affixed.
4. fastening the lead in handle rotating member internal cross bar.
Take the operating process of peach:
1. left hand holds adjusting rod sliding block, the right hand holds handle but not by lower handle rotating member.
2. mobile shears for picking fruit extends to scissors head part near the peach that need to be picked to suitable position.
3. the right hand is motionless, left hand holds adjusting rod sliding block and slides up and down the position for adjusting upper sword and lower sword.Adjusting rod at this time
Sliding block drives the sliding of coarse adjustment pole, and coarse adjustment pole drives the sliding of fine tuning pole, and fine tuning pole drives adjusting rod top connection sliding, adjusts
Pole top connection drives the translation of ears connecting rod and rotation, ears connecting rod to connect with lower sword around knife bar with movable knife rack and its connected upper sword
Head rotation.
4. the twig where making peach is between upper sword and lower sword.
5. left hand is motionless, the right hand is not unclamped by lower handle rotating member, and twig is cut.Handle rotating member has rotated at this time
One angle drives the lead tied up on handle rotating member cross bar to move down, and lead tension drives the lead other end mobile, draws
The other end of line is the bolt being connected with upper sword, therefore upper sword is rotated around hinged position, and upper sword and lower sword are closed, and completes shearing
Movement.Meanwhile with bolted there are one limit spring, limit spring compressive deformation, is in compressive state at this time.
6. mobile shears for picking fruit, peach is slowly put it on the ground.When cutting twig, upper sword and lower sword are closed, at this time
Upper sword fixture and lower sword fixture have clamped twig, therefore peach will not fall down.
7. left hand is motionless, the right hand unclamps handle rotating member, and twig is unclamped, and completes picking.The right hand unclamps handle rotation
After part, the limit spring of compressive deformation is restored to preloading condition before, and the bolt being connected with upper sword is driven to restore to maximum position
End, upper sword are also restored to maximum position end, and upper sword is separated with lower sword at this time.The lead tension on bolt is tied up to, drives lead another
The handle rotating member of one end restores to maximum deployed position.
8. device restores to default conditions.
In operation process, both hands hold adjusting rod sliding block and handle respectively, and varied angle mechanism uses offset slider-crank machine
Structure, mobile jib make rack, and adjusting rod can be considered as sliding block, by pushing adjusting rod sliding block, directly drive bipitch connecting rod up and down, utilize
Bipitch connecting rod drives blade holder turns, and the knife rest other end is connect with rack by rotary pair, and the other end and cutter head are connected, by adjusting rod
Translation be changed into the rotation of cutter head, thus can adjust cutter head angle for branch situation, pinch handle later and can drive and draw
Line makes cutter head realize shearing function, puts down for growing after higher fruit can clamp after winning to safe altitude, avoids fruit
It falls damage in fact.
