Description

Technical Field

[0001] This utility model relates to the field of garden tree technology, specifically a tree disease and pest prevention device. Background Technology

[0002] As the scale and number of garden trees continue to expand, a wider environment is provided for the spread of pests and diseases. As a result, the number of pests and diseases on tree trunks has gradually increased, which has seriously affected the sustainable development of domestic gardening and forestry production. Common methods for preventing tree pests and diseases include whitewashing, trunk injection, trunk coating, and pesticide application. Among these, whitewashing not only prevents pests and diseases and kills overwintering insect eggs and pathogens, but also provides cold protection and is economical and efficient, making it the most commonly used method for preventing pests and diseases.

[0003] According to the announcement, a tree pest and disease control device includes a moving mechanism, a feeding mechanism mounted on the moving mechanism, a connecting mechanism mounted on the moving mechanism, a first whitening mechanism mounted on the connecting mechanism, and a second whitening mechanism mounted on the first whitening mechanism. The first whitening mechanism includes two first whitening seats, and the second whitening mechanism includes two upper mounting seats, which are fixedly connected to the sides of the first whitening seats. The beneficial effect is that it includes both the first and second whitening mechanisms.

[0004] This device allows adjustment of the lateral distance between the first and second whitening seats via a bidirectional screw on the connecting mechanism, and the front-to-back distance via an adjusting screw. This allows the first and second whitening seats to form rectangles of different sizes, accommodating tree trunks of varying thicknesses for whitening, thus improving the tree's disease and pest control effectiveness. However, this device only sprays trees of different diameters and cannot adjust the spray height, preventing it from reaching all parts of the tree and limiting the spraying range.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Please see Figure 1-4 This utility model provides a technical solution: a tree disease and pest prevention device, including a base 1, a universal wheel 2 fixedly connected to the bottom of the base 1, a push handle 3 fixedly connected to the top left end of the base 1, a lifting mechanism 4 provided at the top right end of the base 1, and a spraying mechanism 5 provided at the top left end of the base 1.

[0031] The lifting mechanism 4 includes a fixed frame 41, which is fixedly connected to the top right end of the base 1. A sliding sleeve 42 is slidably connected to the surface of the fixed frame 41. A first fixed frame 43 is fixedly connected to the surface of the sliding sleeve 42.

A bidirectional screw 49 is rotatably connected to both sides. A second servo motor 411 is fixedly connected to the front of the second fixed frame 48. A moving block 412 is symmetrically threaded on the surface of the bidirectional screw 49. Limiting rods 413 are fixedly connected to the front and rear sides near the right side inside the second fixed frame 48. A protective cover 414 is fixedly connected to the right side of the moving block 412. A first connecting pipe 415 is provided at the bottom of the protective cover 414. A nozzle 417 is fixedly connected to the surface of the first connecting pipe 415 inside the protective cover 414. A second connecting pipe 416 is fixedly connected to the bottom end of the first connecting pipe 415.

[0032] The first fixing bracket 43 has a hole on its front side that matches the output shaft of the first servo motor 46, and the surface of the output shaft of the first servo motor 46 passes through and is rotatably connected to the hole.

[0033] The output end of the first servo motor 46 is fixedly connected to the front end of the rotating shaft 44, and the gear 45 meshes with the rack 47.

[0034] The second mounting bracket 48 has a hole on its front side that matches the output shaft of the second servo motor 411. The output peripheral surface of the second servo motor 411 is penetrated and rotatably connected to the hole.

[0036] The bottom of the protective cover 414 has a hole that matches the first connecting pipe 415, and the surface of the first connecting pipe 415 is penetrated and fixedly connected to the hole. Both ends of the first connecting pipe 415 are fixedly connected to the top of the inner wall of the protective cover 414.

[0037] Example 2

[0038] Please see Figure 5 Furthermore, based on Example 1, a spraying mechanism 5 was obtained.

[0039] The spraying mechanism 5 includes a housing 51, which is fixedly connected to the top left side of the base 1. A material injection pipe 52 is fixedly connected to the top of the housing 51 near the front left side. A pump body 53 is fixedly connected to the top of the housing 51. A feed pipe 54 is fixedly connected to the input end of the pump body 53. A discharge pipe 55 is fixedly connected to the output end of the pump body 53. Telescopic pipes 56 are fixedly connected to both ends of the discharge pipe 55.

[0040] The top of the housing 51 has a hole that matches the feed pipe 54, and the surface of the feed pipe 54 is penetrated and fixedly connected to the hole. The bottom end of the feed pipe 54 is close to the bottom of the inner wall of the housing 51, which makes it easy to extract the paint from the housing 51.

[0041] The other end of the telescopic tube 56 is fixedly connected to the bottom end of the second connecting tube 416.

[0042] In actual operation, when this device is in use, the base 1 is equipped with casters 2 at the bottom and a push handle 3 at the top left. The operator can easily move the entire device to the location where tree pest and disease treatment is needed by holding the push handle 3 and utilizing the rolling characteristics of the casters 2, thus improving the device's mobility and ease of operation. When the height needs to be adjusted, the first servo motor 46 is activated, its output shaft rotates, and drives the fixedly connected rotating shaft 44 to rotate. The first fixed frame 43 has a hole on its front that matches the output shaft of the first servo motor 46, ensuring that the motor output shaft can smoothly drive the rotating shaft 44. When the rotating shaft 44 rotates, the gear 45 fixed in the middle of its surface rotates accordingly. Because gear 45 meshes with racks 47 on the upper and lower sides of the inner wall of fixed frame 41, the rotation of gear 45 is converted into linear motion along the direction of rack 47. Gear 45 drives the first fixed frame 43 connected to it and the sliding sleeve 42 fixed to the first fixed frame 43 to slide up and down along the surface of fixed frame 41, thereby realizing the overall lifting and lowering of the second fixed frame 48 and its accessories installed on the right side of sliding sleeve 42, so that the spray nozzle 417 can reach different height positions of the tree for spraying operations. The second servo motor 411 is started, and its output shaft rotates to drive the bidirectional screw 49 fixedly connected to it to rotate. The front of the second fixed frame 48 has a hole that matches the output shaft of the second servo motor 411 to ensure that the motor output shaft can stably drive the bidirectional screw 49. The surface of the bidirectional screw 49 is symmetrically threaded with moving blocks 412. At the same time, the front and rear sides of the second fixed frame 48 are fixedly connected to limit rods 413 near the right side. The front of the moving block 412 has a hole that matches the limit rod 413, and it is slidably connected to the surface of the limit rod 413 through the hole. The limiting rod 413 limits the moving block 412, so that when the bidirectional screw 49 rotates, the two moving blocks 412 will move in opposite directions along the limiting rod 413. The right side of the moving block 412 is fixedly connected to the protective cover 414. Therefore, as the moving block 412 moves, the two protective covers 414 will open and close to adapt to tree trunks of different diameters.

[0043] Insect-preventing paint can be injected into the housing 51 through the injection pipe 52 to provide paint reserves for spraying operations. The pump 53 is started, and it extracts the paint from the housing 51 through the inlet pipe 54 at the input end. The top of the housing 51 has a hole matching the inlet pipe 54, through which the inlet pipe 54 is fixedly connected and penetrates the surface. The bottom end of the inlet pipe 54 is close to the bottom of the inner wall of the housing 51, facilitating the full extraction of paint from the housing 51. The extracted paint is transported through the outlet pipe 55 at the output end of the pump 53 to the telescopic pipes 56 at both ends. The other end of the telescopic pipe 56 is fixedly connected to the bottom end of the second connecting pipe 416. The paint then travels through the second connecting pipe 416 and the first connecting pipe 415 to finally reach the spray head 417. The telescopic tube 56 can extend and retract with the lifting mechanism 4, ensuring that the paint can be delivered smoothly at different heights. The paint is evenly sprayed onto the surface of the tree trunk through the nozzle 417. Due to the presence of the protective cover 414, the paint drift can be reduced, and the utilization rate and spraying effect of the paint can be improved.
