Background

Every time a spring arrives, a great number of pests such as meadow beetles can propagate in a large quantity, and larvae of the pests can ascend to new branches along the trunk of the tree to suck juice, so that the growth of the tree is threatened, leaf wilting is caused, the growth vigor of the tree is weakened, and even the tree is dead. Because the physical prevention and control method is advocated at present, the use of pesticides is reduced, in order to prevent and control the pests, at present, municipal engineering personnel mainly carry out the pest control by taking measures such as winding adhesive tape or spraying white paint on the trunk of the tree, the purpose is to prevent or reduce the pests from crawling upwards along the trunk of the tree, but the trunk winding adhesive tape belongs to repetitive operation, and the trees have great workload, long working time, low efficiency and great labor capacity which are consumed by manually winding the adhesive tape; in addition, the mode of winding the adhesive tape is high in cost, and the adhesive tape which is easy to paste is adopted because of manual winding, so that the cost of tree protection is increased, the width of the adhesive tape is limited, the cost is higher if the wider adhesive tape is needed, or two groups of adhesive tapes can be wound, and the winding cost and the labor amount are also increased. The white paint spraying is another protection method, namely a layer of white quicklime and the like are brushed on the trunk at the height of 1.2-1.5 m, and the white paint can reflect sunlight, reduce the heat absorption of the trunk, and further prevent the trunk from cracking due to huge day and night temperature difference; meanwhile, the white coating also has the functions of sterilization and insect prevention; the freezing injury in winter can be reduced; in addition, a winding adhesive tape can be combined above the whitewashing part, and the winding adhesive tape and the whitewashing part can jointly form a measure for preventing insects of trees.

Chinese patent application number is 202122789083.5, the patent name is an automatic trunk protection against insects sticky tape winding machine, wherein the support frame is L type support body, be equipped with two slides along vertical direction on the stand portion of L type support body, and two slides set up along the width direction symmetry of L type support body, every slide and the stand portion fixed connection of L type support body, auxiliary positioning mechanism sets up on the stand portion in the support frame, and auxiliary positioning mechanism and support frame sliding connection, track platform sets up on auxiliary positioning mechanism, and track platform and auxiliary positioning mechanism fixed connection, sticky tape winding mechanism sets up on the track in the track platform, and sticky tape winding mechanism passes through the track fixed connection in connecting slider and the track platform. The mode of manual winding sticky tape has been solved to a certain extent to it, but its problem that exists is: the adopted support frame is an L-shaped support body, one trunk is required to be lifted to the other trunk every time the trunk is wound, and the operation of winding adhesive tapes is not needed manually, but the device is carried back and forth and operated, so that more heavy manual labor is needed, sometimes even two people are needed to lift the machine, the whole device is heavy in weight, and even a moving wheel is arranged below the device, the device cannot freely walk on the loose soil in a tree forest; moreover, the structure of the utility model is complex, and the adhesive tape is still adopted as a material for winding the trunk, so that the use cost is relatively high, and the device is not popularized and approved in the market.

In summary, it is necessary to invent a handheld trunk insect-proof film winding device and a using method thereof.

The handheld trunk insect prevention film winding device according to claim 1, wherein: more than one sleeve (450) is fixed at the side end of the inner wall of the winding ring (400), sliding rods (452) are connected to the inner wall of the sleeve (450) in a sliding mode, and positioning wheels (440) are connected to one end, away from the sleeve (450), of each sliding rod (452) in a rotating mode through a fixing frame.

8. The handheld trunk insect prevention film winding device of claim 7, wherein: the one end that slide bar (452) inserted sleeve (450) inner wall all is fixed with the short board, the one end that the short board kept away from spring (451) all is fixed with spring (451), the one end that the short board was kept away from to spring (451) is fixed with the inner wall of sleeve (450).

9. The handheld trunk insect prevention film winding device according to claim 6 or 8, wherein: the insect-proof film (b) comprises more than one group of insect-proof film sections (b 1), point-off interfaces (b 1.1) are arranged between the two insect-proof film sections (b 1), adhesive areas (b 1.3) are respectively arranged on two sides of each point-off interface (b 1.1), and protective strips (b 1.2) are adhered to the outer parts of the adhesive areas (b 1.3).

10. A method of using the handheld trunk insect prevention film winding device of claim 9, wherein: the method comprises the following operation steps:

s1: firstly, an operator adjusts and controls the sliding block (411) to enable the position of the winding ring (400) to adapt to the diameter size of the trunk (a), then the device is moved to the position of the trunk (a) to be wound by the hand-held handle (110), and then the trunk (a) is sent to the inner sides of the base (100) and the rotating ring (200) through the opened opening (130);

s2: after an operator adjusts the winding ring (400), the set positioning wheel (440) can enable the spring (451) to be in a compressed state under the action of approaching to the trunk, and the set winding ring (400) can position the trunk under the action of the positioning wheel (440) and the sleeve (450); the servo motor controls the electric control telescopic rod (430) to stretch so that the tail end of the insect-proof film is positioned on the outer wall of the compression wheel (433), and the insect-proof film is compressed;

s3: then, starting a driving motor (300), driving the limiting driving roller (310) to rotate through the belt pulley assembly (320), driving the rotating ring (200) to rotate on the annular sliding rail (120) through the meshed effect when the limiting driving roller (310) rotates, driving the winding ring (400) to coaxially rotate through the supporting rod (410), and pasting the insect-preventing film (b) on the outer wall of the trunk (a) under the rotating effect of the winding ring (400) due to the fact that the tail end of the insect-preventing film (b) is compressed by the compressing wheel (433), reserving a gap between the pasting wheel (432) and the trunk (a), winding the insect-preventing film (b) on the outer wall of the trunk (a), and pasting the insect-preventing film by pulling out the protective strip (b 1.2) after the winding ring (400) rotates for more than one circle, wherein the point-breaking interface (b 1.1) at one side of the next insect-preventing film section (b 1) of the insect-preventing film (b) is compressed by the compressing wheel (433), and pasting the insect-preventing film and the trunk of the tree is pasted; then, winding is continued on the next tree.
