Description

Technical Field

[0001] The present application relates to the field of tree painting, and in particular to a tree whitewashing tool. Background Art

[0002] Trunk whitewashing means that the trunk is painted with a layer of white liquid by workers. Its main purposes include:

[0003] 1. Sterilize, prevent bacterial infection, and accelerate wound healing.

[0004] 2. Pest control and pest prevention. Whitewashing can kill overwintering insect eggs and trunk-boring insects in the bark. Since pests generally prefer black areas to white areas, white lime water applied to the trunks can effectively prevent soil pests from climbing up the tree along the trunks, and also prevent the bark from being bitten by animals.

[0005] 3. Prevent frost damage and sunburn, and avoid early spring frost damage. In winter, the temperature is very low at night, and the trunk loses heat and is in a low temperature state; during the day, the dark brown trunk is easy to absorb heat, and under the influence of sunlight, the trunk temperature will rise quickly; this cold and hot situation makes the trunk easy to be frozen and cracked. After applying lime water, because the lime is white, it can reflect 40%-70% of the sunlight, thus reducing the temperature difference between the day and night of the trunk, making it less likely to crack. At the same time, it can also delay the budding and flowering period of fruit trees and prevent early spring frost damage.

[0006] Because the existing white-painting equipment has poor performance, in order to improve the efficiency and effect of white-painting, our company has independently developed a white-painting tool. Utility Model Content

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Example 1

[0034] like Figure 1-4As shown, a tree whitewashing tool includes a hand-held rod 1, a mounting block 2 arranged at the front end of the hand-held rod 1, an opening and closing adjustment structure arranged on the mounting block 2, and a whitewashing part arranged on the mounting block 2 and matched with the opening and closing adjustment structure; the front end of the mounting block 2 is a mounting platform 17, and the whitewashing part is arranged on the mounting platform 17.

[0035] The opening and closing adjustment structure consists of a limiting groove 3 opened on the mounting block 2 and penetrating the mounting block 2 forward, a slider 4 arranged in the limiting groove 3 and slidable along the limiting groove 3, and a double-sided rack 5 arranged at the front end of the slider 4 and perpendicular to the bottom of the limiting groove 3; the bottom of the limiting groove 3 and the mounting platform 17 are located in the same plane.

[0036] The forward and backward sliding of the slider can control the forward and backward movement of the double-sided rack, and then the forward and backward movement of the double-sided rack can change the opening and closing angles of the two mother arc blocks. The different opening and closing angles of the mother arc blocks make the product suitable for trees of different diameters.

[0037] The bottom of the limiting groove 3 is provided with a plurality of latch holes 19 , and the slider 4 is provided with a latch rod 18 which penetrates the slider 4 and has a diameter matching the latch hole 19 .

[0038] When the latch stick is inserted into the latch hole, the slider can be effectively fixed in the current position, thereby preventing the opening and closing angle of the female arc block from changing due to operating errors during use of the product, and effectively improving the stability of the product.

[0039] The white coating part is composed of two main arc blocks 7 symmetrically arranged on the left and right sides of the double-sided rack 5, sub-arc blocks 9 respectively arranged on the two main arc blocks 7, arc tubes 20 respectively arranged on the inner sides of the main arc block 7 and the sub-arc blocks 9, and a plurality of nozzles 12 respectively arranged on the arc tubes 20; each of the arc tubes 20 is externally connected to a manual pump or an automatic pump through a pipeline; the rear end of the main arc block 7 is provided with a gear 6 that matches the double-sided rack 5.

[0040] The prepared whitening liquid can be pumped into the arc tube by a manual pump or an automatic pump, and finally sprayed out by the nozzle. According to actual use conditions and use requirements, the liquid can also be pumped into the arc tube by a manual pump or an automatic pump to treat insects on the tree trunk.

[0041] The nozzle is a prior art. First, a hole is set on the arc tube, and then the nozzle is fixed in the hole for use. When necessary, a nozzle with an adjustable nozzle spraying mode or an adjustable nozzle spraying direction can be selected. When it is not necessary to use all the nozzles, the nozzle can be turned on or off according to the specific usage of the nozzle. The specific nozzle selection is a conventional technical means in this field. Technical personnel in this field can complete the selection or replacement of the nozzle according to actual needs when necessary, so it will not be elaborated here.

[0042] There are two gears 6 arranged on each of the mother arc blocks 7, and they are respectively arranged on the upper and lower sides of the mother arc block 7; the two gears 6 on the upper and lower sides of the mother arc block 7 are penetrated by the same rotating shaft and fixed on the mounting platform 17, and the two gears 6 on the upper and lower sides are fixed as a whole with the mother arc block 7.

[0043] By arranging gears on the upper and lower sides of the mother arc block, the consistency of the upper and lower ends of the mother arc block during the opening and closing process can be effectively guaranteed, thereby avoiding the situation where the mother arc block gets stuck during opening and closing due to uneven force when the product is in use, and better reducing the damage or deformation of the mother arc block caused by jamming, thereby better improving the use effect of the product and reducing the maintenance frequency of the product.

[0044] In addition, an interference fit can be adopted between the rotating shaft and the mounting platform, so that the rotating shaft can be detachably set on the mounting platform. This facilitates the disassembly, replacement and maintenance of the product, and allows the product to be used normally when only the mother arc block and related accessories on one side are installed, thereby further improving the scope of application of the product.

[0045] An arc-shaped limit head 16 is respectively disposed at the front and rear ends of the double-sided rack 5 .

[0046] The purpose of setting the arc limit head is to better limit the movement range of the double-sided rack, to prevent the double-sided rack from disengaging from the gear when the forward and backward movement range is too large, effectively ensuring the meshing effect of the gear and the double-sided rack, and at the same time better ensuring that the angle between the two mother arc blocks will not change due to the disengagement between the double-sided rack and the gear, thereby ensuring the weight balance on the left and right sides of the product when in use.

[0047] A driving limit block 8 is provided at the front end of the mother arc block 7, and the driving limit block 8 is provided in an inverted "U" shape, and an opening running through the front and back of the driving limit block 8 located on the inner side of the mother arc block 7 is provided, and the width of the opening matches the nozzle 12; a power supply and a driving motor are provided in the driving limit block 8, and a bevel gear 14 is provided on the output shaft of the driving motor; the driving motor is connected to a controller by wire or wirelessly.

[0048] According to actual use requirements, the controller can be made into a handheld independent controller, or fixedly set on a handheld rod for the convenience of users to operate during use. The main function of the controller is to control the drive motor to rotate forward or reverse.

[0049] The sub-arc block 9 passes through the driving limit block 8, and an arc rack 13 matching the bevel gear 14 is arranged on the upper side of the sub-arc block 9; a front annular limit block 11 is arranged around the front end of the sub-arc block 9, and a rear limit block 15 is arranged at the rear end; a semicircular touch head 10 is also arranged at the front end end of the sub-arc block 9.

[0050] Since the bevel gear is meshed with the arc rack, when the bevel gear rotates, it can drive the arc rack to move forward or backward, and then drive the sub-arc blocks to close forward or open backward through the arc rack.

[0051] The touch head can be made of flexible material, and its function is to reduce the collision strength when the sub-arc blocks touch each other, and better protect the product components from damage due to touch. If the sub-arc blocks continue to move toward each other after the touch heads touch due to operational errors, the front annular limit block can effectively limit each other to prevent the sub-arc blocks or arc racks from deforming due to mutual collision; at the same time, when the sub-arc blocks move away from each other, the front annular limit block can also effectively prevent the sub-arc blocks from being over-retracted, thereby ensuring that the arc rack will not be separated from the bevel gear, and also ensuring that the sub-arc block will not move backwards and collide with the gear. The rear limit block can effectively limit the extension length of the sub-arc block to prevent the sub-arc block from falling off due to excessive extension.

[0052] The position of the arc tube 20 on the sub-arc block 9 matches the position of the opening of the drive limit block 8 , and the position of the nozzle 12 on the arc tube 20 matches the position of the opening of the drive limit block 8 .

[0053] This arrangement ensures the normal movement of the sub-arc block and the passability of the nozzle, effectively improving the reliability of the product.

[0054] Example 2

[0055] The only difference between this embodiment and embodiment 1 is that a sliding groove with the same direction as the limiting groove 3 is respectively arranged on the left and right side walls of the limiting groove 3, and a limiting sliding block matching the sliding groove and capable of sliding along the sliding groove is respectively arranged on the left and right sides of the sliding block 4.

[0056] Providing a sliding groove in the limit groove and providing a limit slider on the slider can effectively limit the range of motion of the slider, avoid operating errors that cause the slider to be lifted from the limit groove, and better ensure the reliability of product use.

[0057] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0058] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims. The protection scope of the utility model is defined by the claims and their equivalents.
