Description
Technical field
The present invention provides a kind of automatic lifting for spray boom pesticide applicator and damping self-balancing mechanism, is mainly used for spray boom and applies
Medicine machine, belongs to agricultural mechanical field.
Background technique
Currently, pesticide applicator has become the important component of equipment for plant protection, and spray rod type pesticide applicator has operating efficiency high
The features such as automating is folded with spray boom, has been used widely.The processes such as spray rod type pesticide applicator spray lance lifting, stretching, extension and folding
Often there is the problems such as mechanism is easy to wear, lifting action stability is poor, while even there is also stretching, extension, jackknife actions to need multistep
Suddenly operate and fold situations such as not in place；In hillside fields when operation, spray boom understands upper and lower, double swerve, and pesticide applicator walking process also can
Because the processes such as equipment speed-raising, deceleration and steering cause spray boom to sway forwards and backwards, it is affected to pesticide supplying effect.Spray rod type pesticide applicator is past
Longer toward spray bar length, spray boom damping effect in the case where " pendulum is trembled " acts on is poor, easily causes spray boom to fracture, spray boom end is contacted to earth, and shadow
Ring pesticide supplying effect.To ensure that preferable pesticide supplying effect, nozzle majority are that fan-shaped or taper, the distance between spray head are liftoff with spray head
The spacing in face need to be corresponded to strictly.The walking of spray boom pesticide applicator is in the field of earth's surface injustice, and spray boom is by from front and back, upper and lower and left and right
" shaking " in direction and influence spray boom stability, i.e. the shaking of spray boom causes spray boom and ground there are angle, and spray head is from the ground
Spacing real-time change, balance are poor, this will directly affect the pesticide supplying effect of pesticide applicator.

Between III right side retainer plate of crossbeam, " cavity " formed on the inside of two lapping plates, on the inside of single hole link block is fixed with by articulated shaft
The axis of bumper post cylindrical, articulated shaft is consistent with the round hole axial on lapping plate, and the circular hole and buffering of lapping plate
The through-hole perpendicular to axis direction in the middle part of column is affixed, and the circular hole on 2 pieces of single hole link blocks is bolted, and towards spray boom
Pesticide applicator direction of advance sees that bumper post is located at the right side of single hole link block connection bolt, the right end of connecting rod I and the middle part of crossbeam II
Equipped with damper.
Its working principle is that: the left and right side arm for connecting spray boom be connected to wave the connecting rod of connection frame end and
Between two link slots, the spray boom of horizontally disposed pesticide applicator is separately mounted to wave the bottom end of connection frame bottom end and left and right side arm,
When pesticide applicator original state is that two sides side arm is in folded state, " hook " of adjustment plate II is pulled in " hook " of hanger plate
Together, connecting rod I and connecting rod II are in parastate, and the front and back 2 of the hinge joint of the front and back of connecting rod I 2 and connecting rod II
A hinge joint forms a parallelogram, and when two sides side arm will be unfolded, I fuel feeding of hydraulic cylinder, the cylinder rod of hydraulic cylinder I shortens,
It waves and is lifted on connection frame, the cylinder rod of upper lift process hydraulic cylinder II is constantly in non-elongate state, " hook " of adjustment plate II and hangs
" hook " of hook plate is no longer pulled together, and adjustment plate II pushes down always the hanger plate of I side of hydraulic cylinder, when waving on connection frame
When lift to certain altitude (ensuring that side arm carries out expansion movement, no interference object), the elongation of operation handle, first II cylinder rod of hydraulic cylinder
To range, while adjustment plate II no longer pushes down hanger plate, and then side arm starts to spread out, I fuel feeding of hydraulic cylinder, hydraulic cylinder I
Cylinder rod is elongated, waves connection frame decline, while spray boom also synchronous decline, medical fluid can be sprayed by reaching suitable location.When spray boom needs
When reducing height, connection frame decline is waved in the elongation of I cylinder rod of hydraulic cylinder, while spray boom reduces downwards；When spray boom needs to lift height
When spending, I cylinder rod of hydraulic cylinder shortens, and waves and lifts on connection frame, while spray boom is lifted up.
Connecting rod I and connecting rod II with support I, pulling plate, hydraulic cylinder III form " four-bar mechanism " after connecting, when walking along
Spray boom pesticide applicator direction fluctuation is indefinite, when fluctuating biggish out-of-flatness earth's surface, causes to shake because spray boom pesticide applicator own wt is larger
Pendulum connection frame and its left and right side arm connected generate the shaking of all directions.It is seen towards spray boom pesticide applicator direction of advance, works as production
It when the connection frame shaking of side direction to the left is waved in life, waves and is increased on the left of connection frame, pulling plate lower part is mobile to upper left side, is applied to
Power on the pressure spring of left side becomes larger, while lower section is mobile to the left for III cylinder rod end of hydraulic cylinder, and the power being applied on the pressure spring of right side becomes larger,
Damper is pressurized, and the collective effect of left and right sides pressure spring and damper, which forces, waves connection frame balance；Towards before spray boom pesticide applicator
It is seen into direction, when the shaking of connection frame right direction is waved in generation, vice versa.
It is seen towards spray boom pesticide applicator direction of advance, when waving connection frame and generating upward shaking, waves connection frame plummet
It moves up, plummet moves up simultaneously for pulling plate lower part, III cylinder rod end of hydraulic cylinder, is applied to left side, the power on the pressure spring of right side becomes
Small, damper tension waves connection frame balance, vice versa；When spray boom pesticide applicator bears the synthesis side of left and right and up and down direction
To shaking when, similarly can reach wave connection frame balance.When hillside fields operation, higher item is distinguished on right side, left side ground
Under part, III cylinder rod of hydraulic cylinder respectively corresponds shortening, elongation, waves connection frame balance.Operation finishes, the process that left and right side arm folds
It is opposite with the movement of expansion.
Compared with prior art, the present invention I cylinder rod length of hydraulic cylinder becomes when spray boom needs reduction or raising height
Change, wave connection rack position and also change therewith, achievees the purpose that the lift adjustment of spray boom, and lifting device is easy to adjust and goes up and down
Stable action.Damping device can make full use of the damping characteristics of cushion block to reach damping purpose, when waving connection frame generation shaking,
Connection frame movement is waved, pulling plate lower part, III cylinder rod end of hydraulic cylinder also act therewith, is applied to left side, the power on the pressure spring of right side becomes
Change, damper resistance variation, waves connection frame and reach balance, is i.e. self balancing device makes full use of pressure spring and the comprehensive of damper to make
With can preferably reach the purpose of self-balancing.
