Power regulation operating mechanism mainly adjusts partial constitutions such as eccentric wheel, main control valve, power motion sensor joint and power regulating spring by power regulation control handle, power. Control handle homoenergetic control main control valve is adjusted to power, position. Be elected to when adjusting hard, must adjust the control handle to the position and pull to " promotion " position and locking, when selecting for use the position to adjust, also must adjust the control handle to power and pull to " promotion " position and locking, avoid the mutual interference. It is nimble to ensure that manipulation rotate handle is adjusted to power, position, must not have the jamming phenomenon. This patent can effectively guarantee the tractor power, that configuration operation adjust to be controld to the position is simple and convenient, resources are saved reduces cost of maintenance, reaches control main control valve, realizes that machines promote, the decline automatic control agricultural implement farming degree of depth and promotions need.
Description
Technical field
This utility model relates to the power of tractor, position regulates operating mechanism, is a kind of operating mechanism for controlling agricultural machinery and implement and the tilling depth distance on ground in tractor lifting mechanism.
Background technology
The effect of the lifter operating mechanism of tractor makes as desired to handle main control valve so that agricultural machinery and implement promote, decline or automatically control agricultural machinery and implement tilth and raised position.
In tractor lifting mechanism, power, position regulate that control crank is mainly used in ploughing, resistivity changes greatly the field of (or there is fluctuating on ground) and carries out operation.Power, position regulate control crank and use proper, protect agricultural machinery and implement, and the plantation etc. of crops has all been played critically important effect.The power of current tractor, position regulate operating mechanism structure complexity, adjust constant, use to vast farmers and bring serious inconvenience, cause because using lifter spoilage height that is constant and that formed, and maintenance cost strengthens.
Summary of the invention
The purpose of this patent is in that: provide the power of a kind of tractor, position to regulate operating mechanism, can be effectively ensured the power of tractor, position regulate handle structure easy and simple to handle, economize on resources, reduce maintenance cost, reach to control main control valve, it is achieved facility promote, declining automatically controls agricultural machinery and implement tilth and promote needs.
The technical solution of this patent is: position regulates handle structure and regulated the parts such as tension spring 19, position eccentric adjustment wheel 8, fanning strip 3, woodruff key 4, rotating casing 6, lift shaft 16, main control valve 21 and position control cam 22 formed by position adjustment control crank 2, position adjustment lever 18, position.Position eccentric adjustment wheel 8 and a rotating casing 6 weld together, and position is regulated control crank 2 and is connected with rotating casing 6 by woodruff key 4.Position regulates on lever 18 empty set eccentric adjustment wheel 8 in place.When position adjustment control crank 2 moves forward and backward, the effect of the lower end adjustment tension spring 19 in place driving rotating casing 6 to make position regulate lever 18 is contacted with the position control cam 22 being fastened in lift shaft 16 with screw 14 down, when agricultural machinery and implement promote or decline, the position control cam 22 also concomitant rotation in lift shaft 16.When position regulates control crank 1, to be in a certain given position motionless, position regulates the upper end of lever 18 and swings with the rotation of position control cam 22, to reach the effect that position regulates control end D feedback control main control valve 21 position of lever 18 bottom, so as to return to " neutrality " state, agricultural machinery and implement are made to reach a certain assigned altitute and stop.
Power regulates operating mechanism and is regulated sensor connector 13, screw 14, push rod 15, push pedal 23 and power adjustment spring 24 etc. partly formed by power adjustment control crank 1, power adjustment lever 20, power adjustment tension spring 17, power eccentric adjustment wheel 9, fanning strip 3, woodruff key 4, mandrel 5, lift shaft 16, main control valve 21, power.Power eccentric adjustment wheel 9 and mandrel 5 are welded into one, and power is regulated control crank 1 and is connected with mandrel 5 by woodruff key 4, and power regulates lever 20 empty set and takes turns on 9 at power eccentric adjustment.When power adjustment control crank 1 moves forward and backward, power can be made to regulate the lower control terminal E swing of lever 20, control the position of main control valve 21, to reach lifting or the decline of agricultural machinery and implement.Owing to being arranged on the push rod 15 that power regulates the upper end of lever 20, regulate in power and contact with the push pedal 23 being fastened on power adjustment lever 20 front end with screw 14 under the effect of tension spring 17, when farming, when the resistance of colter is changed by soil, the stress of the upper connecting rod of hitch also changes, and pass to associated power adjustment sensing joint 11, then compression stress regulates spring 24, the effect of lever 20 and push rod 15 is regulated by power, make power regulate lever 20 and take turns 9 swings around power eccentric adjustment, power regulates lever 20 lower control terminal E makes main control valve 21 position change.
Power, position regulate control crank and all can control main control valve.Elected when firmly regulating, it is necessary to position to be regulated control crank 9 and pulls to " lifting " position and lock；When selecting position to regulate, it is also necessary to power is regulated control crank 10 and pulls to " lifting " position and lock, it is to avoid interfere with each other.It is ensured that power, position adjustment control crank rotate flexibly, must not there is catching phenomenon.
Power adjustment control crank 1 is locked or position regulates control crank 2 locking mechanism mainly by alignment pin 25, sleeve pipe 10, spring 11, packing ring 12 part such as grade forms, power regulates control crank 1, position regulates control crank 2, fanning strip 3 forms by having certain thickness steel plate swaging, but should be taken into account certain rigidity simultaneously, therefore, these three steel plate thickness is respectively set as Amm, Bmm, Cmm, then 4mm≤A or B≤6mm, 2mm≤C≤3.5mm, alignment pin 25 is in the hole of fanning strip 3, sleeve pipe 10 is enclosed within alignment pin 25, the exterior power of sleeve pipe 10 regulates control crank 1, alignment pin 25 regulates control crank 1 or the outer assembling spring 11 respectively of position adjustment control crank 2 in power, packing ring 12, wing nut 26 and split pin 27.When not needing under normal condition to lock, the spring 11 being enclosed within alignment pin 25 should keep natural length state, front portion wing nut 26 and split pin 27 are pinned, when power regulates control crank 1 or position adjustment control crank 2 respectively when " lifting " position and when need to lock, wing nut 26 should be continued make spring 11 compress coupling mechanism force to fanning strip 3 direction precession and regulate control crank 1 or position adjustment control crank 2 so as to be adjacent to sleeve pipe 10.
This utility model has the advantage that
1, this adjustment operating mechanism is simple and convenient, feeds back sensitive, wide accommodation.
If 2, this adjustment operating mechanism maintenance cost is cheap and in use go wrong, it is simple to search reason and be easy to maintenance, adapt to the demand of different different user.
