Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, specifically a tree trunk whitening mechanism. Background Technology

[0002] Agriculture is mainly divided into two categories: agricultural planting and agricultural animal husbandry. As a basic industry of the national economy, agriculture is important in many aspects, such as ensuring food security, supporting social stability, promoting economic development, maintaining ecological balance, and inheriting cultural values.

[0003] As an agricultural product, apples have the advantages of wide planting range, high survival rate and good fruit storage properties, making them suitable for large-scale planting.

[0004] After planting, apple trees need to have their trunks whitewashed. This is to prevent the trees from being damaged by frost due to large temperature fluctuations in winter. The quicklime and salt in the whitewash also have bactericidal and disinfectant properties, which can kill bacteria and insect eggs at the base of the trunk. In addition, whitewashed apple trees look cleaner and more beautiful.

[0005] In the initial stage of whitewashing, lime is generally chosen as the main material. After adding water, the lime is brushed onto the tree trunk. With the development of agricultural technology, other ingredients such as sulfur and salt are added to the whitewashing agent. It is sold as a finished product with a finer texture and can be directly sprayed using a spraying machine, which is more labor-saving than brushing.

[0006] Among the applications found, one application with application number 202420928986.8 describes a whitewashing device for tree trunks used in landscaping. This novel whitewashing device uses a rack and pinion plate to drive a gear in reverse, causing the spray ring to slide inside a movable plate and move to the other half of the tree trunk's outer wall. This allows the nozzle to spray the other half of the trunk while the movable plate is descending, improving the spraying efficiency. However, the device has the following drawbacks:

[0007] Existing spraying equipment is limited to small fruit trees because taller devices can interfere with branches extending from the sides of the trees. Therefore, there is an urgent need to improve the spraying components to use flexible handheld devices to spray white on the tree trunk in one go, which can be used on a variety of trees, saving time and effort and improving work efficiency. Utility Model Content

[0008] The purpose of this utility model is to provide a tree trunk whitening mechanism in order to solve the above-mentioned problems.

[0009] The technical solution adopted by this utility model is as follows: A tree trunk whitening mechanism includes a main rod, a main feed pipe and a sprayer. The main feed pipe is provided with the outlet of the sprayer. The main rod is located outside the sprayer. A longitudinal handle is integrally provided at the tail end of the main rod. A sliding groove is provided in the middle of the main rod. A slider is slidably connected inside the sliding groove. A transverse handle is fixedly connected to both sides of the slider.

[0010] The end of the main pole is equipped with a white spraying mechanism that can spray white paint around the trunk;

[0011] The whitening mechanism includes a positioning head, a tee connector, a connecting hole, a force-bearing column, a long screw, a torsion spring, a support frame, a fan-shaped nozzle, a connecting lug, and a feeding hose;

[0012] The main rod has an integrated positioning head at the top end, a three-way connector is installed in the lower middle part of the positioning head, and support frames are symmetrically and rotatably connected to both sides of the positioning head. Fan-shaped nozzles are embedded in the inner side of each support frame, and connecting ears are integrated at the ends of each support frame.

[0013] Both the connecting ear and the positioning head have a through-hole. A force-bearing column is integrally formed on the side of the connecting ear and the positioning head near the connecting hole. A long screw is movably connected inside the connecting hole. A torsion spring is nested outside the long screw. The extension hook of the torsion spring is hooked between the connecting ear and the force-bearing column on the positioning head. Hanging rings are provided on the surfaces of the slider and the two support frames. Pull ropes are connected between the hanging rings.

[0014] Each of the support frames is equipped with a feeding hose on the outside, and the fan-shaped nozzle is connected to the feeding hose. One end of each of the two feeding hoses is sealed, and the other end is connected to a T-connector, which is connected to the other end of the main feeding pipe.

[0015] The support frame has a semi-circular design.

[0016] The longitudinal grip and the lateral grip are set at a 90° angle.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the user pulls the horizontal handle, causing the slider to slide to one side along the groove. This causes the two support frames to open to both sides under the pull of the rope, allowing the support frames to be placed over the tree trunk. After the user releases the horizontal handle, the force on the torsion spring disappears, and the two support frames return to their original position under the torsion of the torsion spring, thus encircling the tree trunk. The user can then hold the main pole and move it up and down to spray the entire tree trunk, making the spraying work more time-saving and efficient.

[0019] 2. In this utility model, the two semi-circular support frames can better fit the shape of the tree trunk, and with the fan-shaped nozzles spraying evenly, the spraying area of ​​the device can be increased, thereby improving efficiency. At the same time, this device can operate on trees of various sizes, with a larger operating range. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In this utility model:

[0028] Reference Figure 1-5 A tree trunk whitening mechanism includes a main rod 1, a main feed pipe 302 and a sprayer 7. The main feed pipe 302 is provided at the outlet of the sprayer 7. The main rod 1 is located outside the sprayer 7. A longitudinal handle 101 is integrated at the tail end of the main rod 1. A sliding groove 102 is provided in the middle of the main rod 1. A slider 2 is slidably connected inside the sliding groove 102. A transverse handle 201 is fixedly connected to both sides of the slider 2.

[0029] The end of the main pole 1 is equipped with a white spraying mechanism that can spray white paint around the trunk;

[0030] The whitening mechanism includes a positioning head 3, a three-way connector 301, a connecting hole 4, a force-bearing column 401, a long screw 402, a torsion spring 403, a support frame 5, a fan-shaped nozzle 501, a connecting ear 502, and a feeding hose 6.

[0031] The main rod 1 has an integrated positioning head 3 at the front end. A three-way connector 301 is installed in the lower middle part of the positioning head 3. Support frames 5 are symmetrically rotated and connected on both sides of the positioning head 3. Fan-shaped nozzles 501 are embedded in the inner side of the support frames 5. Connecting ears 502 are integrated at the ends of the support frames 5.

[0032] Both the connecting lug 502 and the positioning head 3 have connecting holes 4 extending through their surfaces. A force-bearing column 401 is integrally formed on the side of both the connecting lug 502 and the positioning head 3 near the connecting hole 4. A long screw 402 is movably connected inside the connecting hole 4, and a torsion spring 403 is nested outside the long screw 402. After the long screw 402 passes through the connecting lug 502 and the connecting hole 4 of the positioning head 3, the long screw 402 rotates as a bearing, and the extension hooks of the torsion spring 403 hook between the connecting lug 502 and the force-bearing column 401 on the positioning head 3. The slider 2 and the two support frames 5 are all equipped with hanging rings, and a pull rope is connected between the hanging rings. When spraying the tree trunk, the user pulls the horizontal handle 201, causing the slider 2 to slide to one side along the slide groove 102. This causes the two support frames 5 to open to both sides under the pull of the pull rope, so that the support frames 5 can be placed on the outside of the tree trunk. After the user releases the horizontal handle 201, the force on the torsion spring 403 disappears, and the two support frames 5 return to their original position under the torsion of the torsion spring 403, thus wrapping around the tree trunk and facilitating subsequent spraying work.

[0033] Each support frame 5 is equipped with a material supply hose 6 on its exterior, and the fan-shaped nozzle 501 is connected to the material supply hose 6. One end of each of the two material supply hoses 6 is sealed, and the other end is connected to a three-way connector 301. The three-way connector 301 is connected to the other end of the main material supply pipe 302. The white paint is pressurized by the spraying machine 7 and delivered to the main material supply pipe 302. Then, it is diverted through the three-way connector 301 to the material supply hoses 6 at both ends, and finally sprayed evenly through the fan-shaped nozzle 501 to spray the surface of the tree trunk.

[0034] Furthermore, the support frame 5 has a semi-circular design. The two semi-circular support frames 5 can better fit the shape of the tree trunk and also form a surrounding spray, making the spraying efficiency higher and more uniform.

[0035] Furthermore, the vertical grip 101 and the horizontal grip 201 are set at a 90° angle, allowing the user to hold the vertical grip 101 with one hand and control the horizontal grip 201 with the other. This two-handed operation is more ergonomic and less strenuous to use.

[0036] Furthermore, the spraying machine 7 consists of a hopper and a spraying pump. The inlet of the spraying pump is connected to the hopper, the outlet of the spraying pump is connected to the main feed pipe 302, and the spraying pump is electrically connected to an external power supply via a switch.

[0037] Working principle: First, the user holds the longitudinal handle 101 with one hand and controls the transverse handle 201 with the other. Working in coordination, when spraying the tree trunk, the user pulls the transverse handle 201, causing the slider 2 to slide to one side along the groove 102. This causes the two support frames 5 to open to both sides under the pull of the rope, allowing the support frames 5 to be fitted over the tree trunk. After the user releases the transverse handle 201, the force on the torsion spring 403 disappears, and the two support frames 5 return to their original position under the torque of the torsion spring 403, thus encircling the tree trunk. The two semi-circular supports... The support frame 5 can better fit the shape of the tree trunk and also form a circumferential spray. Next, the sprayer 7 is turned on, and the white paint is pressurized and delivered to the main feed pipe 302 through the sprayer 7. Then, it is diverted to the feed hoses 6 at both ends through the three-way connector 301. Finally, it is evenly sprayed out through the fan-shaped nozzle 501. The fan-shaped nozzle 501 has a large spraying range. The user can hold the main pole 1 and move it up and down to spray the entire tree trunk, making the spraying work more time-saving and efficient. After the spraying is completed, the support frame 5 is opened by pulling the horizontal handle 201 to carry out the next operation.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
