Description

Technical Field

[0001] This utility model relates to the field of plant protection equipment for cotton planting, specifically to a cotton plant protection device with adjustable spray height and row spacing. Background Technology

[0002] Many problems are encountered in the process of cotton cultivation, but with the development of industrialized cultivation, cotton cultivation has been mechanized.

[0003] During the cotton growth process, mechanized operations such as spraying pesticides and fertilizing are required during the seedling and growth stages to ensure the normal growth of cotton.

[0004] Existing plant protection equipment mostly uses a bracket to install several nozzles and a tractor as the locomotive (traction power) to achieve mechanized spraying. Although it can complete the spraying work, it is inadequate when dealing with furrows with different spacing, cotton plants of different heights and growth stages. It is also prone to damaging taller plants.

[0005] Although the existing tractors are equipped with hydraulic devices that can raise the overall height, it is clear that they cannot properly coordinate with the equipment for spraying, especially when the plants are tall, as most of the sprayed pesticide is concentrated on the top leaves of the plants.

[0006] Therefore, there is a need for a plant protection device that can adjust the spray height and row spacing, and can effectively spray pesticides onto plants of different heights. Utility Model Content

[0007] To address the aforementioned problems, this invention provides a cotton plant protection device with adjustable spray height and row spacing.

[0008] This utility model is achieved through the following technical solution: An adjustable spray height and row spacing cotton plant protection device includes a mobile frame. A drive motor is fixedly installed on one side of the mobile frame. A lead screw is fixedly connected to the output end of the drive motor. A lead screw assembly is installed on the lead screw.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: like Figure 1 , Figure 2 As shown, a cotton plant protection device with adjustable spray height and row spacing includes a mobile frame 1. A drive motor 2 is fixedly installed on one side of the mobile frame 1. A lead screw 3 is fixedly connected to the output end of the drive motor 2. A lead screw assembly 4 is installed on the lead screw 3. Hinge rods 5 are hinged to both sides of the lead screw assembly 4 via hinge pins. A fixed frame 9 is fixedly installed on the mobile frame 1. Two sliding frames 6 are slidably connected to the mobile frame 1. The fixed frame 9 is positioned between the two sliding frames 6. One end of the lead screw 3 is rotatably connected to the side wall of the fixed frame 9. One end of each hinge rod 5 is connected to the corresponding sliding frame 6 via a hinge pin. The moving frame 6 is hinged, and connecting rods 7 are fixedly connected to the side walls of the two sliding frames 6 and the fixed frame 9. A fixed block 8 is fixedly connected to one end of each connecting rod 7. A spray box 12 is installed on each fixed block 8. When adjusting the spacing, the drive motor 2 is started, which causes the lead screw 3 to rotate, thereby driving the lead screw assembly 4 to move, which causes the hinge rod 5 to move, thereby causing the sliding frame 6 to move, which in turn drives the corresponding fixed block 8 to move. The middle fixed block 8 is fixed, thus realizing the spacing adjustment between multiple fixed blocks 8.

[0017] A connecting frame 10 is installed directly above the mobile frame 1. The connecting frame 10 is fixedly connected to the external traction equipment. The connecting frame 10 is in an inverted U-shape. An electric telescopic rod 11 is fixedly installed on the inner top surface of the connecting frame 10. The output end of the electric telescopic rod 11 is fixedly connected to the top of the mobile frame 1. Both ends of the connecting frame 10 pass through the mobile frame 1 and are slidably connected to it. When adjusting the height, the electric telescopic rod 11 is activated, and the connecting frame 10 is fixedly connected to the connecting part at the rear of the tractor. This allows the mobile frame 1 to be raised and lowered, thereby achieving height adjustment.

[0018] A spray box 12 with a sliding connection is inserted into the fixed block 8. A telescopic frame 17 is fixedly connected to one side of multiple spray boxes 12. The telescopic frame 17 consists of three telescopic cylinders and two telescopic rods. The two telescopic rods are fixed on both sides of the middle telescopic cylinder. The two telescopic rods are inserted into the telescopic cylinders on both sides and slidably connected to them. The cross-section of the telescopic cylinders and the telescopic rods is square. An adjusting screw 18 is screwed onto the middle telescopic cylinder. The bottom end of the adjusting screw 18 is rotatably connected to the top of the fixed block 8 in the middle. For plants of different heights, the height of the moving frame 1 has been adjusted by the electric telescopic rod 11. At this time, the adjusting screw 18 is rotated to adjust the height of the spray box 12, thus meeting the usage requirements and ensuring that the plants can be sprayed from all directions. This also prevents the spray box 12 from contacting the ground. The telescopic frame 17 is provided so that it can be well used in conjunction with the spacing adjustment structure to avoid jamming.

[0019] Multiple sets of nozzles 13 are fixedly installed on the spray box 12. Each set of nozzles 13 is evenly arranged from top to bottom to achieve comprehensive spraying of the plants.

[0020] A limiting rod 14 is fixedly connected to one side of the fixing block 8. The limiting rod 14 is U-shaped, and a sealing plate 15 is fixedly connected to one end of the limiting rod 14. An inlet pipe 16 is fixedly inserted through the sealing plate 15. Each sealing plate 15 is inserted into the corresponding spray box 12 and slides in close contact with it. After the inlet pipe 16 is connected to the hose, the medicine can enter the spray box 12 from the medicine tank along the hose and the inlet pipe 16, thereby providing medicine to the nozzle 13 for spraying. For plants of different heights, the depth of the sealing plate 15 entering the spray box 12 is first adjusted according to the height of the plant to block unnecessary nozzles 13 and avoid waste of medicine. Then the electric telescopic rod 11 is activated to adjust the overall height, thereby achieving all-round spraying.
