[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1As shown, a cold-proof whitewashing device for landscape trees includes a cart 5, a hard pipe 4 and a storage barrel 6, and is characterized in that: the storage barrel 6 is fixedly connected to the rear of the upper end of the cart 5, a water pump is fixedly connected between the hard pipe 4 and the storage barrel 6, the hard pipe 4 and the storage barrel 6 are respectively fixedly connected to the output end and the input end of the water pump, the upper end of the hard pipe 4 is fixedly connected to a bellows 7 communicated with its inner cavity, the upper end of the bellows 7 is fixedly connected to a hard pipe 2 8 communicated with its inner cavity, the left side of the front upper end of the cart 5 is fixedly connected to a support assembly 1, and the left end of the hard pipe 2 8 is fixedly connected to an adjustment device 3.

[0027] During the specific implementation of this solution, the cart 5 is first pushed to the side of the tree, so that the adjusting device 3 is placed on one side of the tree, which is convenient for whitewashing the tree. Then, the adjusting device 3 can be started to rotate 45 degrees to the front and left, and the support assembly 1 and the water pump can be started to drive the adjusting device 3 to move up and down to whitewash the root of the tree. Then, the adjusting device 3 is started to rotate 135 degrees to the right rear to whitewash the other half of the root area of ​​the tree. The whitewashing of the tree is completed mechanically. In the process of using the support assembly 1, when the adjusting device 3 is placed at the lower part, the supporting rod 51 is used to tilt the adjusting device 3 downward to ensure that the root of the tree is completely whitewashed without leaving any blank space, thereby further ensuring the effect of keeping out the cold.

[0028] Specifically, in order to reduce the labor pressure of workers and improve the efficiency of whitewashing, refer to Figure 4 and Figure 5 The regulating device 3 includes a semicircular spray plate 31 slidably connected to the hard pipe 28, a plurality of spray heads 32 are fixedly connected to the inner surface of the semicircular spray plate 31 in an annular array, a hose 33 is arranged inside the semicircular spray plate 31, two ends of the hose 33 are connected to the side wall on the same side of the inner surface of the semicircular spray plate 31 and communicate with the inner cavity of the semicircular spray plate 31, a rotating assembly 34 is fixedly connected to the lower end of the semicircular spray plate 31, and a plurality of springs are sleeved on the outer surface of the hose 33;

[0029] For further information, see Figure 4 The rotating assembly 34 includes a half gear ring 341, the lower end of the half gear ring 341 is slidably connected to a casing 342, the outer surface of the half gear ring 341 is meshedly connected to a gear 343, the lower end of the gear 343 is fixedly connected to a second motor 344, the second motor 344 passes through the casing 342 and the gear 343 in sequence through the coupling at the output end, extends to the top wall of the inner surface of the casing 342 and is rotatably connected to the casing 342, and the second motor 344 is fixedly connected to the casing 342 through a connecting seat;

[0030] For further information, see Figure 4 , the semi-toothed ring 341 is fixedly connected to the semicircular spray plate 31, and the sleeve 342 is fixedly connected to the hard pipe 28;

[0031] The left and right sides of the middle hose 33 have extra length inside the semicircular spray plate 31 to ensure that the hard tube 2 8 and the hose 33 are always fixedly connected when the semicircular spray plate 31 rotates, and the paint supply is always smooth.

[0032] The spring pieces on the outer surface of the above-mentioned middle hose 33 can be squeezed out from the inside of the semicircular spray plate 31 together with the hose 33 being squeezed. While the hose 33 is being squeezed out, the hose 33 is always kept in a round and unbent state by using a plurality of spring pieces, so that the paint can be smoothly transported into the semicircular spray plate 31 to supply a plurality of nozzles.

[0033] It can be seen that the initial position of the hard tube 2 8 is placed in the middle of the outer surface of the semicircular spray plate 31, and the position of the semicircular spray plate 31 is placed on the upper part of the support assembly 1. When the semicircular spray plate 31 is placed outside the tree, the motor 2 344 can be started to drive the gear 343 to rotate, and the gear 343 can drive the semi-gear ring 341 to slide on the bottom wall of the inner surface of the casing 342 and rotate 45 degrees to the left. At this time, the semicircular spray plate 31 also slides on the left end of the hard tube 2 8 so that the rear side of the outer surface of the semicircular spray plate 31 corresponds to the position of the hard tube 2 8, so that the middle of the semicircular spray plate 31 corresponds to the front position of the outer side of the tree;

[0034] During the rotation of the semicircular spray plate 31, the hose 33 at the rear is squeezed and squeezed out from the inner surface of the semicircular spray plate 31. At this time, the hose 33 does not fold and remains smooth with the help of a number of springs on the outer surface of the hose 33. The reserved hose 33 at the front is stretched, so that the semicircular spray plate 31 rotates smoothly.

[0035] After the position is adjusted, start the water pump to extract the paint inside the storage barrel 6, transport it into the hose 33 through the hard pipe 1 4, the corrugated pipe 7 and the hard pipe 2 8, and spray the lower part of the trunk through a plurality of nozzles 32. During the spraying process, start the support assembly 1 to drive the adjusting device 3 to move up and down, and the whitewashing of the front area of ​​the trunk can be completed, that is, half of the whitewashing can be completed. The support assembly 1 can be used to drive the adjusting device 3 to move up and down repeatedly to increase the number of spraying layers. After the spraying is completed, the adjusting device 3 is still placed on the upper part of the support assembly 1. At this time, start the motor 2 344 again to drive the semicircular spray plate 31 to rotate 135 degrees to the right rear, and spray the rear side of the trunk. In this way, the whitewashing of the trees is completed mechanically, which improves the whitewashing work efficiency.

[0036] Specifically, to ensure that the bottom of the tree trunk is completely white, refer to Figure 2 and Figure 3 The support assembly 1 includes a fixed plate 11 and a connecting plate 15. The right end of the connecting plate 15 is fixedly connected to two front-to-back symmetrical support plates 16. The ends of the two support plates 16 close to each other are rotatably connected to the sleeve 12. A support plate 13 is provided on the left side of the lower part of the outer surface of the sleeve 12. A spring 14 is fixedly connected between the support plate 13 and the connecting plate 15.

[0037] For further information, see Figure 3 , the hard tube 8 is sleeved inside the casing 12;

[0038] For further information, see Figure 2 The front and rear parts of the lower end of the fixed plate 11 are both provided with a guide rod 111 and a reciprocating screw 112 which penetrate the connecting plate 15 and extend to the lower part of the lower end of the connecting plate 15. The guide rod 111 and the reciprocating screw 112 are respectively slidably connected and threadedly connected to the connecting plate 15. The reciprocating screw 112 is rotationally connected to the fixed plate 11. The lower end of the reciprocating screw 112 is fixedly connected to a motor 113. The guide rod 111 and the motor 113 are both fixedly connected to the cart 5.

[0039] For further information, see Figure 2 The upper end of the cart 5 is fixedly connected with a support rod 51 corresponding to the position of the hard pipe 8;

[0040] It can be seen that during the start-up of the support assembly 1, the motor 113 is first started to drive the reciprocating screw 112 to rotate, which can drive the connecting plate 15 to reciprocate up and down. The connecting plate 15 cooperates with the guide rod 111 to maintain its own stability during the up and down movement, so as to maintain the stability of the spraying of the adjustment device 3, thereby ensuring the uniformity of the white coating. The hard tube 2 8 can be driven to move up and down through the sleeve 12 and the support plate 16, so as to achieve the up and down reciprocating movement of the adjustment device 3. During the up and down movement of the hard tube 2 8, the corrugated tube 7 will be straightened or rolled up accordingly. Due to the material characteristics of the corrugated tube 7 itself, no bending will occur during this process, so as to facilitate the smooth supply of paint.

[0041] In addition, when the adjusting device 3 is placed at the lower part of the guide rod 111, as the connecting plate 15 continues to move downward, when the sleeve 12 contacts the supporting rod 51, the supporting rod 51 can hold the right part of the sleeve 12. At this time, the sleeve 12 will rotate to the lower left under the action of the two supporting plates 16. At this time, the left part of the sleeve 12 will squeeze the supporting plate 13 to compress the spring 14. At this time, the adjusting device 3 can be tilted to the lower left, which is convenient for whitewashing the roots of trees and avoiding missing some areas. When the connecting plate 15 moves upward, it can drive the sleeve 12 to gradually move away from the supporting rod 51 and no longer press the sleeve 12. At this time, under the action of the spring 14, the supporting plate 13 and the sleeve 12 are gradually reset. In this process, the right part of the sleeve 12 rotates to the lower right until the sleeve 12 is placed in a horizontal position.

[0042] It should be particularly noted that the specific installation method, circuit connection method and control method of the motor 1 113 and the motor 2 344 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
