in the corresponding spray head assembly and the half holding cylinder: the spray head assembly comprises an arc-shaped pipe 421 fixed on the half holding cylinder and a plurality of spray heads 422 communicated with the arc-shaped pipe, the arc-shaped pipe is attached to the inner side wall of the half holding cylinder, and the arc-shaped pipe is communicated to the pressing type liquid spraying pump through a liquid spraying outlet hose 43;

the ring suction mechanism comprises a press type liquid suction pump 5 and two liquid suction devices which are in one-to-one correspondence with the half holding cylinders, the press type liquid suction pump is communicated to the liquid storage tank through a liquid suction outlet pipe 51, and the liquid suction devices and the half holding cylinders are correspondingly arranged: the liquid suction device comprises a plurality of liquid suction components, and each liquid suction component comprises an arc-shaped seat plate 52 fixed with the lower end of the half holding cylinder;

in a wicking assembly: the liquid suction component also comprises an arc-shaped moving seat 53 which can be attached to the inner side wall of the arc-shaped seat plate, an arc-shaped adhesive tape 54 arranged on the arc-shaped moving seat and a pushing cylinder 55 for driving the arc-shaped moving seat to move, wherein the pushing cylinder comprises a pushing cylinder body 551, the pushing device comprises a pushing inner piston 552 in sliding sealing fit with a pushing cylinder body and a pushing piston rod 553 arranged on the pushing inner piston, wherein a pushing spring 554 is sleeved on the pushing piston rod, one end of the pushing spring is connected with the pushing inner piston, the other end of the pushing spring is connected with the pushing cylinder body, the pushing piston rod is in sliding connection with an arc-shaped seat plate, the pushing cylinder body is fixed on the arc-shaped seat plate through a cylinder support 555, a plurality of adhesive tape liquid suction ports 54a are formed in the top of the arc-shaped adhesive tape, a plurality of adhesive tape liquid suction ports are formed in one side, far away from the pushing cylinder, of the arc-shaped adhesive tape, adhesive tape inner channels communicated with all the adhesive tape liquid suction ports are formed in the arc-shaped adhesive tape, and the adhesive tape inner channels are communicated to a pressing type liquid suction pump through a liquid suction hose 56;

the vehicle body is provided with an inflator 16 for inflating the pushing cylinder and an inflating air supply pipe 17 communicated with the inflator, one end of the inflating air supply pipe is an air receiving cylinder end communicated with an air outlet end of the inflator, the other end of the inflating air supply pipe is an inflating air supply end, the pushing cylinder is communicated to the inflating air supply end through the pushing air pipe, the inflating air supply pipe is provided with an air outlet branch pipe, and the air outlet branch pipe is provided with an air outlet on-off valve;

When the invention is positioned on a horizontal ground, the distance between the highest point of any arc-shaped rubber strip and the ground is less than 10 cm. The vehicle body is provided with a kettle rack, and the kettle rack is provided with a watering can clamped with the kettle rack. The spraying pot is filled with protective liquid.

In the prior art, when the trunk needs to be whitewashed, if the brush is used, the whitewashing efficiency is low, the labor intensity of gardeners is high, whether the trunk is fully whitewashed or not can not be well guaranteed, and all whitewashing areas are judged by observing the gardeners, so that carelessness is avoided. In addition, if a large amount of the protective solution is dipped with a brush every time in order to make the protective solution as white as possible, the protective solution is wasted because the excess protective solution flows down, a part of the flowing protective solution adheres to the trunk, and the rest of the protective solution flows to the soil completely. If the spray gun (or other conventional sprayers) is used, a gardener is required to observe and spray while spraying, and the waste of the protective liquid is serious when the spray gun is used for spraying, because a large amount of protective liquid flows down along the trunk when the spray gun is used for spraying, one part of the flowing protective liquid is attached to the trunk, and the other parts of the flowing protective liquid completely flow to soil and are wasted.

In the invention, a protective liquid is stored in a liquid storage tank, when a trunk needs to be whitewashed, the lock catch and the lock body are separated, the half holding cylinders rotate along the axes of the movable hinge shafts corresponding to the half holding cylinders, so that the two half holding cylinders are relatively opened, gardeners hold the push-pull handle (the left hand holds one push-pull handle, the right hand holds the other push-pull handle) to enable the trunk to enter between the two half holding cylinders, then the two half holding cylinders are relatively closed, the lock catch and the lock body are locked and fixed, at the moment, the trunk is positioned in the surrounding holding cylinders, and the trunk and the surrounding holding cylinders are similar to coaxial arrangement.

The gardener utilizes the inflater to give each propelling movement cylinder air feed (inflate), and propelling movement main cavity grow, and piston, propelling movement piston rod, arc move seat, arc adhesive tape move towards the trunk direction together in the propelling movement, push the trunk until the arc adhesive tape, because the arc adhesive tape has elasticity, so can paste the trunk better on. It should be emphasized that the trunk surface is not flat, so that the "bark slit" surface recessed toward the inside of the trunk is not completely adhered to the arc-shaped rubber strip (the "bark slit" pressed by the arc-shaped rubber strip has a small gap with the arc-shaped rubber strip, which will be described later, and the "bark slit" is referred to as the "bark slit" pressed by the arc-shaped rubber strip).

The gardener lets push type hydrojet pump work with push type imbibition pump together, and push type hydrojet pump work draws the protective liquid from the liquid storage tank to let the protective liquid go out hose, arc pipe, each shower nozzle blowout through the hydrojet, thereby spout the trunk on, owing to "hydrojet mechanism includes a plurality of hydrojet wares that arrange in proper order from top to bottom", "in a hydrojet ware: all the spray heads are sequentially and uniformly distributed along the circumferential direction of the encircling cylinder, so that the spraying of each liquid sprayer to the trunk is the 'encircling spraying' of the whole trunk in the circumferential direction. Each sprayer ring is with protection liquid "the ring spouts" back on the trunk, partly protection liquid is attached to the trunk on, all the other protection liquid down flows along the trunk, protection liquid down flows along the trunk in-process, there is some protection liquid to attach to the trunk again, down flow arc adhesive tape department when protection liquid, partly protection liquid direct inflow "bark seam", all the other protection push type liquid flows arc adhesive tape top, because the work of imbibition pump, each adhesive tape imbibition mouth department all has suction, thereby can be with "bark seam", a large amount of protection liquid at arc adhesive tape top is siphoned away, and through the adhesive tape inner path, imbibition advances the hose and inhales the push type imbibition pump, the liquid storage pot is sent back to the rethread imbibition exit tube, thereby can greatly avoid extravagant.

In addition, the arc-shaped rubber strips are not completely attached to the bark gaps, a distance exists between the arc-shaped rubber strips and soil (in practice, the distance is small, for example, in the case that the distance between the highest point of any arc-shaped rubber strip and the ground is less than 10 cm when the invention is positioned on the horizontal ground), most of the protective liquid flowing into the bark gaps is sucked away from the rubber strip liquid suction ports (a plurality of rubber strip liquid suction ports are formed in one side, far away from the pushing cylinder, of each arc-shaped rubber strip), and the protective liquid which is not sucked away continuously flows down and is attached to the surface of the trunk close to the soil.

After each spray head sprays liquid for a plurality of times, the main whitewashing process is completed, the trunk above each arc-shaped adhesive tape is fully 'circularly sprayed' through each liquid sprayer, enough protective liquid is adhered, and the redundant protective liquid is always recovered at the liquid suction port of each adhesive tape, so the protective liquid is not afraid of being wasted on the premise of full spraying.

After the spraying process is finished, a gardener opens the air-release on-off valve to release air for the pushing main cavity, and under the action of the pushing spring, the pushing inner piston, the pushing piston rod, the arc-shaped moving seat and the arc-shaped adhesive tape reset and then close the air-release on-off valve. Then, the lock catch and the lock body are separated, the half holding cylinders rotate along the axes of the movable hinge shafts corresponding to the half holding cylinders, so that the two half holding cylinders are relatively opened, a gardener holds the push-pull handle to pull the tree trunk surface away, and then observes the surface of the trunk close to the soil, because the white coating at the position is completely dependent on the protective liquid flowing down from the bark seam, the situation of insufficient spraying is possible, and at the moment, if the coating needs to be supplemented, the gardener can supplement the coating with a spraying pot (or a brush, a spraying gun and other conventional tools).

According to the traditional whitening operation (spraying operation), all areas to be whitened depend on observation and spraying of gardeners, and the waste of the protective liquid is serious.

The friction between the movable hinge shaft and the fixed hinge body is self-locked.

As previously stated, most protective liquids for whitewashing, whose main component comprises lime milk, contain a large amount of solid matter, and once left to stand for a long time, the "concentration" of the protective liquid in the lower part of the tank is high and the "concentration" of the protective liquid in the upper part of the tank is low, which is disadvantageous for the spraying operation. Because the liquid supply position of the liquid storage tank is arranged close to the bottom of the liquid storage tank (the liquid cannot be supplied outwards when a large amount of protective liquid is still in the liquid storage tank). Therefore, once the protection liquid in the liquid storage tank is not uniform enough, the concentration of the protection liquid which can be sprayed out at the beginning is high, which is easy to cause waste, and when the storage amount of the protection liquid in the liquid storage tank is low, the concentration of the protection liquid which can be continuously sprayed out is insufficient, which is easy to cause insufficient protection effect after whitewashing.

Therefore, when the spraying, the protection liquid in the liquid storage tank is best through fully stirring, and does not stand for too long after stirring (if it is too long to stand, then protection liquid "concentration" of the lower part in the liquid storage tank can be obviously higher than protection liquid "concentration" of the upper part in the liquid storage tank, and the protection liquid in the liquid storage tank needs to be fully stirred again at this moment), so that the component proportion of the sprayed protection liquid can be guaranteed to be reasonable.

In this scheme, before the spraying, the protection liquid uniform degree in the liquid storage tank is not enough. At first, when the bottom of the cylinder pipe piston contacts the lower cylinder limiting body, the liquid homogenizing front pipe hole, the piston middle cross hole and the liquid homogenizing rear pipe hole are communicated in sequence, the liquid spraying front pipe hole is sealed by the cylinder pipe piston, the liquid spraying rear pipe hole is sealed by the cylinder pipe piston, the chute notch is sealed by the cylinder pipe piston, and the inner magnetic rod is positioned in the limiting groove. In the process that the hydrojet footboard reciprocated for the first several times, when the hydrojet footboard shifts up, partly protective solution in the liquid storage tank got into the hydrojet main cavity through the hydrojet exit tube, and when the hydrojet footboard shifted down, air and protective solution in the hydrojet main cavity have two to go to, and first goes to and is: the protective liquid in the liquid storage tank is stirred from bottom to top, namely, is pre-stirred once, and solid substances are deposited at the bottom of the liquid storage tank, so that the stirring effect is excellent; the second direction is: the liquid level in the lower cylinder cavity rises after entering the lower cylinder cavity through the liquid separation preposed pipe and the liquid separation preposed pipe hole, a part of air in the lower cylinder cavity is pressed into the transverse hole in the piston through the lower vertical hole of the piston, the air is pressed into the transverse hole in the piston, and then enters each tank bottom connecting pipe through the liquid homogenizing rear pipe hole and the liquid homogenizing rear pipe, the liquid level in the lower cylinder cavity is higher and higher along with the continuous up-and-down reciprocating movement of the liquid spraying pedal (the protective liquid in the lower cylinder cavity falls back to the liquid storage tank through the lower cylinder hole, but the bore diameter of the lower cylinder hole is too small relative to that of the liquid separation preposed pipe hole, so the amount of the protective liquid flowing out of the lower cylinder cavity in unit time is obviously less than the amount of the protective liquid entering the lower cylinder cavity in unit time), the buoyancy force borne by the vertical buoy is larger and larger, but the cylinder pipe piston is 'heavier', so the vertical buoy can not jack the cylinder pipe piston, and the liquid level reaches the position of the upward one-way valve at a certain moment, after that, once the protection liquid continues to enter the lower cylinder cavity from the liquid separation front pipe hole, the lower cylinder cavity becomes large, and the cylinder pipe piston also moves upwards (after the liquid level reaches the ascending one-way valve, once the protection liquid continues to enter the lower cylinder cavity from the liquid separation front pipe hole, if the transverse hole in the piston is communicated with the pipe hole after liquid homogenizing, a small amount of protection liquid is pressed into the transverse hole in the piston through the vertical hole in the piston, but most of the protection liquid remains in the lower cylinder cavity, and the lower cylinder cavity is full, so the lower cylinder cavity becomes large, and the cylinder pipe piston also moves upwards).

And because of buoyancy, the vertical float bowl, outer magnetic block will also move up (when the outer magnetic block moves up or down, if the outer magnetic block and cylinder tube piston move relatively, the vertical slide bar and slide hole can play a guiding role), at a certain moment, the cylinder tube piston moves up to contact the upper cylinder limiting body, at this moment, the outer magnetic block has reached the side of the chute notch due to the floating up of the vertical float bowl, the outer magnetic block has magnetic attraction to the inner magnetic rod, one end of the inner magnetic rod extends out of the chute, and the inner magnetic rod and the outer magnetic block are magnetically adsorbed and fixed (contacted with each other), at this moment, the inner magnetic rod contacts the outer magnetic block, the top of the inner magnetic rod contacts the bottom of the cylinder tube piston, the top of the outer magnetic block contacts the bottom of the cylinder tube piston, the top of the cylinder tube piston contacts the upper cylinder limiting body, the front liquid spray tube hole, the transverse hole on the piston and the rear liquid spray tube hole are sequentially communicated, the front liquid homogenizing tube hole is sealed by the cylinder tube piston, in this state, when the liquid spraying pedal moves downwards, the air and the protective liquid in the liquid spraying main cavity also have two directions, wherein the first direction is as follows: the tree trunk is sprayed by a liquid spraying preposed pipe, a liquid spraying front pipe hole, a piston upper transverse hole, a liquid spraying rear pipe, a liquid spraying outlet hose, an arc-shaped pipe and all nozzles, and the second direction is as follows: and the liquid falls back to the liquid storage tank through the liquid separation preposed pipe, the liquid separation front pipe hole, the lower cylinder cavity and the lower cylinder hole. Before the inner magnetic rod contacts the outer magnetic block, a large amount of air and protective liquid enter the liquid storage tank through the bottom holes of the liquid storage tank, so that the protective liquid in the liquid storage tank is pre-stirred for multiple times, namely, a pre-mixing process is fully completed, and in the later spraying operation, a part of protective liquid falls back to the liquid storage tank from a lower cylinder hole, namely, the protective liquid in the liquid storage tank is slightly stirred (the degree of the slight stirring is lighter compared with the degree of the pre-stirring).

After the "premixing process" is completed, continued "gentle agitation" provides good maintenance of the uniformity of the protective solution within the reservoir. Therefore, if the liquid ejection is continued for a while thereafter, the "gentle agitation" is continued, so that the uniformity of the protective liquid in the liquid storage tank is ensured. In other words, the homogeneity of the protection liquid in the tank begins to become less than reasonable (requiring a new "premixing process") only after a certain time after the "gentle agitation" has ceased.

If liquid spraying is stopped at a certain moment, in a period of time just after liquid spraying is stopped, because the top of the inner magnetic rod contacts the bottom of the cylinder pipe piston, the cylinder pipe piston cannot move downwards, and a state that a hole before liquid spraying, a hole on the piston and a hole after liquid spraying are sequentially communicated is kept, in the state, if spraying operation is carried out, liquid spraying can be performed to be whitewashed, meanwhile, the protection liquid in the lower cylinder cavity also continuously flows out from the lower cylinder hole and falls back to the liquid storage tank, in the process that the protection liquid in the lower cylinder cavity flows out from the lower cylinder hole, although the liquid level in the lower cylinder cavity is reduced in a period of time, the top of the outer magnetic block is still enough to contact the bottom of the cylinder pipe piston, until the liquid level in the lower cylinder cavity is low at a certain moment, and the resultant force of the buoyancy force exerted on the vertical pontoon and the outward magnetic block of the inner magnetic rod is F (the gravity of the vertical sliding rod is larger than the maximum friction force between the vertical sliding rod and the cylinder pipe piston), f is not enough to continuously support the vertical float bowl and the outer magnetic block, the outer magnetic block and the vertical float bowl fall (the vertical slide rod slides downwards relative to the slide hole), and after the outer magnetic block falls and leaves, the inner magnetic rod returns to the limiting groove under the action of the limiting spring, so that the cylinder tube piston can fall.

After the cylinder pipe piston begins to fall down, two conditions exist, one is that no spraying operation is performed, the cylinder pipe piston is opened and falls until the bottom of the cylinder pipe piston contacts the lower cylinder limiting body, at the moment, if the spraying liquid is required to be whitely coated, the premixing process is performed, the other is that the spraying operation is performed suddenly, the bottom of the cylinder pipe piston does not contact the lower cylinder limiting body, the protection liquid in the lower cylinder cavity begins to increase again, at a certain moment, the cylinder pipe piston rises again until the top of the cylinder pipe piston contacts the upper cylinder limiting body, and a pipe hole before spraying the liquid, a transverse hole on the piston and a pipe hole after spraying the liquid are communicated in sequence.

From the above, when the invention carries out the whitening operation (spraying operation) after standing for a long time, although the action of the gardener is not different from the 'spraying operation', namely, the spraying pedal is repeatedly stepped down and loosened to repeatedly move up and down, but the 'whitening function' is automatically forbidden actually to prevent the 'concentration' of the sprayed protective liquid from being too high, the 'spraying operation' carried out at the moment is actually and automatically converted into the 'pre-stirring' operation, and the 'whitening function' is automatically forbidden after the 'premixing process' is finished, and the 'spraying operation' carried out at the moment is the real whitening operation.
