[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a spraying mechanism, which can realize that the clamping jaw assembly 100 can be adjusted according to the diameter of the tree, so as to adapt to the tree and avoid the waste of whitening liquid. It includes the clamping jaw assembly 100, which includes a connecting seat 101, and also includes a rotating shaft member 102 arranged on the connecting seat 101, and a clamping jaw member 103 rotatably installed on the connecting seat 101, and a spraying assembly 200, which includes a spraying member 201 and a scraping member 202 arranged on the clamping jaw member 103.

[0032] The clamping jaw 103 includes a first clamping jaw 103a and a second clamping jaw 103b rotatably mounted on the connecting base 101. The rotating ends of the first clamping jaw 103a and the second clamping jaw 103b are both provided with tooth blocks 103c, and the tooth blocks 103c on the first clamping jaw 103a are meshed with the tooth blocks 103c on the second clamping jaw 103b.

[0033] In this embodiment, the connecting seat 101 is U-shaped and is used to install the first jaw 103a and the second jaw 103b. The first jaw 103a and the second jaw 103b are both rotatably installed on the connecting seat 101 through the rotating shaft 102, and are respectively located at the two ends of the connecting seat 101. The first jaw 103a and the second jaw 103b are both arc-shaped and can match a semicircular arc. If the diameter of the tree is small, the first jaw 103a and the second jaw 103b can be merged and contacted at one end away from the rotating shaft 102. At the same time, the cross-section of the first jaw 103a and the second jaw 103b is U-shaped, so that the spraying part 201 and the scraping part 202 can be set in the U-shaped groove.

[0034] The scraping member 202 is disposed below the spraying member 201 , and the scraping end of the scraping member 202 protrudes from the U-shaped groove to fit the tree.

[0035] Furthermore, the rotating ends of the first jaw 103a and the second jaw 103b are adjusted by rotating the first jaw 103a according to the diameter of the whitewashed tree through the tooth block 103c. The first jaw 103a drives the second jaw 103b to rotate through the meshing tooth block 103c, so that the first jaw 103a and the second jaw 103b can wrap and fit the outer wall of the tree as much as possible.

[0036] The spraying member 201 includes a hose 201a fixedly mounted on the upper ends of the inner walls of the first clamping jaw 103a and the second clamping jaw 103b, and an atomizing nozzle 201b disposed on the hose 201a.

[0037] The scraper 202 includes a mounting seat 202a disposed at the lower end of the inner wall of the first clamping jaw 103a and the second clamping jaw 103b, and a brush piece 202b disposed in the mounting seat 202a.

[0038] In this embodiment, a plurality of atomizing nozzles 201b are arranged at equal intervals on the hose 201a, and the hose 201a is connected to the whitening liquid. After the whitening liquid enters the hose 201a, it is sprayed onto the tree bark from the plurality of atomizing nozzles 201b, thereby achieving a whitening effect. It should be noted that when whitening the trees, the movement trajectory of the spraying mechanism is from bottom to top, and the brush piece 202b is plugged and installed in the mounting seat 202a and is arranged below the spraying member 201, so that when the whitening liquid sprayed onto the tree bark by the atomizing nozzle 201b flows downward, it is brushed upward by the brush piece 202b, which more effectively makes the whitening liquid flow on the tree bark, avoiding the whitening liquid flowing downward and finally accumulating at the root of the tree.

[0039] The connection between the mounting seat 202a and the brush piece 202b is a mortise and tenon structure, so that the brush piece 202b can be replaced after being worn, and the brush piece 202b is prevented from falling off when the brush piece 202b is scraping the whitening liquid upwards.

[0040] Example 2, reference Figures 1 to 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a rotating shaft member 102 of the spraying mechanism, which realizes the purpose of quickly locking the first clamping jaw 103a and the second clamping jaw 103b after adjustment. It includes the rotating shaft member 102 including a first rotating shaft 102a and a second rotating shaft 102b arranged on the connecting seat 101, and the first rotating shaft 102a and the second rotating shaft 102b are respectively corresponding to the first clamping jaw 103a and the second clamping jaw 103b for rotation installation, the length of the first rotating shaft 102a is greater than the length of the second rotating shaft 102b, and the first rotating shaft 102a is movably plugged into the connecting seat 101 up and down, a stop block 102c is arranged on the first rotating shaft 102a, and the stop block 102c and the tooth block 103c are gap-matched and clamped, a pull ring 102d is arranged on the top of the stop block 102c, and a lifting inclined surface 102c-1 and a stop vertical surface 102c-2 are opened on the stop block 102c.

[0041] A stopper 102e is provided on the circumferential side wall of the first rotating shaft 102a, and a return spring 102f is sleeved on the first rotating shaft 102a. A limiting groove 102g is provided on the connecting seat 101, and a limiting block 102h is provided on the stopper 102e, and the limiting block 102h and the limiting groove 102g are slidably matched.

[0042] In this embodiment, under the action of the return spring 102f, the first rotating shaft 102a makes the gap between the stop block 102c at the top and the tooth block 103c on the first clamp 103a match and engage, and when the stop block 102c is inserted into the gap of the tooth block 103c, the raised inclined surface 102c-1 and the stop vertical surface 102c-2 correspond to two adjacent tooth blocks 103c respectively.

[0043] Furthermore, when adjusting the first clamping jaw 103a and the second clamping jaw 103b according to the diameter of the tree, in the initial state, the first clamping jaw 103a and the second clamping jaw 103b need to be at the maximum angle, so it is necessary to first adjust the first clamping jaw 103a and the second clamping jaw 103b to be unfolded, and by pulling the pull ring 102d upward, the anti-rotation block 102c is disengaged from the gap of the tooth block 103c on the first clamping jaw 103a. At this time, the first clamping jaw 103a is rotated to drive the second clamping jaw 103b to rotate and unfold through the meshing tooth block 103c. After unfolding, so that it can wrap the tree, the first clamping jaw 103a is rotated again. Claw 103a causes tooth block 103c to push the raised inclined surface 102c-1 on the stop block 102c, so that the stop block 102c moves up and over the tooth block 103c and enters the gap of another tooth block 103c. Similarly, when the first jaw 103a is rotated to adjust the contraction, the second jaw 103b will also rotate and contract. When the first jaw 103a and the second jaw 103b hold the tree tightly, one side of the tooth block 103c corresponds to the stop vertical surface 102c-2 on the stop block 102c, thereby preventing the first jaw 103a from rotating in the open direction, and the whitewashing operation can be performed at this time.

[0044] The rest of the structure is the same as that of Example 1.

[0045] Example 3, reference Figures 1 to 5 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a tree whitening device, which solves the problem that the whitening machine is inconvenient to move and difficult to operate. It includes the spraying mechanism in the above embodiment, and also includes a screw slide 300 fixedly connected to the connecting seat 101. The screw slide 300 moves up and down to drive the spraying mechanism to whiten the trees, and a mobile cart 400 on which the screw slide 300 is fixedly installed. The base of the mobile cart 400 is L-shaped, and a triangular wheel 401 is provided at the corner of the L-shape of the base of the mobile cart 400. The triangular wheel 401 design can easily climb over the steps and can be moved by one person. A water tank 402 is provided on the horizontal section of the base of the mobile cart 400, and a cover plate 403 is rotatably installed on the top of the water tank 402. The cover plate 403 can be opened to add whitening liquid into the water tank 402.

[0046] A water pump 404 is provided at the top of the water tank 402. The water inlet of the water pump 404 is connected to the inside of the water tank 402, and the water outlet of the water pump 404 is connected to the hose 201a through a delivery pipe. The water pump 404 draws the whitening liquid in the water tank 402 and delivers it to the hose 201a, and then sprays it out through the atomizing nozzle 201b.

[0047] A stirring motor 405 is provided at the top of the water tank 402, and an agitator 406 is provided inside the water tank 402. One end of the agitator 406 is fixedly connected to the output shaft of the stirring motor 405. The stirring motor 405 drives the agitator 406 to rotate, so that the whitening liquid in the water tank 402 can be mixed evenly, reduce the viscosity, and prevent the whitening agent in the water tank from solidifying.

[0048] A control box 407 is provided at the vertical section of the base of the mobile cart 400, and the control box 407 is electrically connected to the screw slide 300, the water pump 404 and the stirring motor 405 through wires.
