Description

Automatic lifting and damping self-balancing mechanism for spray rod pesticide applying machine

Technical Field

The invention provides an automatic lifting and damping self-balancing mechanism for a spray boom pesticide applying machine, which is mainly used for the spray boom pesticide applying machine and belongs to the field of agricultural machinery.

Background

At present, the pesticide applying machine becomes an important component part of plant protection machinery, and the spray rod type pesticide applying machine has the characteristics of high operation efficiency, automatic spray rod folding and the like, and is widely applied. The problems of easy abrasion of a mechanism, poor stability of lifting action and the like exist in the lifting, stretching and folding processes of a spray rod type pesticide spraying machine, and the conditions that the stretching and folding actions need multi-step operation, are not folded in place and the like exist at the same time; when the spraying rod is in operation on sloping fields, the spraying rod can shake up and down and left and right, and the spraying rod can shake back and forth due to the processes of accelerating, decelerating, steering and the like of the machine tool in the running process of the pesticide applying machine, so that the pesticide applying effect is greatly influenced. The spray rod type pesticide spraying machine is long in spray rod length, the shock absorption effect of the spray rod is poor under the action of 'swinging', and the spray rod is easy to break, the tail end of the spray rod touches the ground, so that the pesticide spraying effect is affected. In order to ensure better application effect, most of the nozzles are fan-shaped or cone-shaped, and the distance between the spray heads is strictly corresponding to the distance between the spray heads and the ground. The spray rod pesticide applying machine walks in the field with uneven ground surface, the spray rod is subjected to 'shake' from front and back, up and down and left and right directions to influence the stability of the spray rod, namely, the spray rod and the ground are inclined by the shake of the spray rod, the distance between the spray head and the ground is changed in real time, and the balance is poor, so that the pesticide applying effect of the pesticide applying machine is directly influenced.

round hole on 2 single hole connecting blocks passes through bolted connection, and see towards spray lance pesticide application machine advancing direction, the buffer column is located single hole connecting block connecting bolt's right side, the right-hand member of connecting rod I and the middle part of crossbeam II are equipped with the attenuator.

The working principle is as follows: the left side arm and the right side arm of the connecting rod of the connecting spray rod are respectively connected between the tail end of the connecting pull rod of the swinging connecting frame and the two connecting grooves, the spray rod of the horizontally arranged pesticide applying machine is respectively arranged at the bottom end of the swinging connecting frame and the bottom ends of the left side arm and the right side arm, when the initial state of the pesticide applying machine is that the two side arms are in a folding state, the hook of the adjusting plate II and the hook of the hook plate are pulled together, the connecting rod I and the connecting rod II are in a parallel state, the front hinge point and the rear hinge point of the connecting rod I and the front hinge point and the rear hinge point and form a parallelogram, when the two side arms are about to be unfolded, the hydraulic cylinder I supplies oil, the cylinder rod of the hydraulic cylinder I is shortened, the cylinder rod of the hydraulic cylinder I is lifted upwards, the cylinder rod of the lifting process is always in a non-extension state, the hook of the adjusting plate II and the hook of the hook plate are not pulled together, the adjusting plate II always presses the hook plate on the side face of the hydraulic cylinder I, when the swinging connecting frame is lifted to a certain height (the side arm is ensured to be unfolded, no interference object), the handle is operated, the hydraulic cylinder II is firstly extends to the maximum stroke, the adjusting plate I is simultaneously, the cylinder rod II is not pushed down, the hook plate I is not to be unfolded, the position is simultaneously, the hydraulic cylinder I is unfolded, and the hydraulic cylinder I is suitable to be simultaneously, and the hydraulic cylinder I is simultaneously lowered, and the position is suitable for the hydraulic cylinder is simultaneously to be lowered. When the spray rod needs to be lowered in height, the cylinder rod of the hydraulic cylinder I stretches, the swing connecting frame descends, and the spray rod descends downwards; when the spray boom needs to be lifted, the cylinder rod I of the hydraulic cylinder is shortened, the swing connecting frame is lifted, and meanwhile the spray boom is lifted upwards.

The connecting rod I and the connecting rod II are connected and then form a four-bar mechanism with the support I, the pull plate and the hydraulic cylinder III, and when the vehicle walks on uneven ground with rough fluctuation along the direction of the spray rod pesticide applying machine, the swing connecting frame and the left and right side arms connected with the swing connecting frame are caused to swing in all directions due to the fact that the self weight of the spray rod pesticide applying machine is large. When the swinging connecting frame swings towards the left direction when the spraying rod pesticide applying machine is seen in the advancing direction, the left side of the swinging connecting frame is lifted, the lower part of the pulling plate moves towards the left upper side, the force applied to the left side pressure spring is increased, meanwhile, the end part of the cylinder rod III of the hydraulic cylinder moves towards the left lower side, the force applied to the right side pressure spring is increased, the damper is pressed, and the combined action of the left side pressure spring, the right side pressure spring and the damper forces the swinging connecting frame to balance; when the swinging connecting frame swings rightwards when seen in the advancing direction of the spray rod applicator, the reverse is opposite.

When the swing connecting frame swings upwards when the spray rod pesticide applying machine is seen in the advancing direction, the plumb of the swing connecting frame moves upwards, the lower part of the pull plate and the end of the III cylinder rod of the hydraulic cylinder move upwards at the same time, the force applied to the left pressure spring and the right pressure spring is reduced, the damper is pulled, the swing connecting frame is balanced, and the reverse is also carried out; when the spray rod pesticide applying machine bears the shaking of the comprehensive direction of the left and right direction and the up and down direction, the balance of the swinging connecting frame can be achieved in the same way. When the sloping field works, under the condition that the ground on the right side and the ground on the left side are respectively higher, the cylinder rod of the hydraulic cylinder III is correspondingly shortened and lengthened respectively, and the swinging connecting frame is balanced. After the operation is finished, the folding process of the left side arm and the right side arm is opposite to the unfolding action.

Compared with the prior art, when the spray rod needs to be lowered or lifted, the length of the cylinder rod of the hydraulic cylinder I is changed, the position of the swinging connecting frame is also changed, the purpose of lifting and adjusting the spray rod is achieved, and the lifting device is convenient to adjust and stable in lifting action. The damping device can fully utilize the buffering characteristic of the cushion block to achieve the damping purpose, when the swinging connecting frame shakes, the swinging connecting frame acts, the lower part of the pulling plate and the end of the III cylinder rod of the hydraulic cylinder also act along with the swinging connecting frame, the force applied to the left pressure spring and the right pressure spring changes, the resistance of the damper changes, and the swinging connecting frame is balanced, namely the self-balancing device fully utilizes the comprehensive effect of the pressure spring and the damper, and the purpose of self-balancing can be better achieved.
