Technical Field

[0001] This invention belongs to the technical field of spraying devices, specifically relating to a dual-track spraying device suitable for the entire growth period of wheat and corn. Background Technology

[0002] Wheat and corn are important food crops in agricultural production, with a wide planting area. Pest and disease control is crucial during the growth cycle of wheat or corn, and spraying is one of the key methods for pest and disease control.

[0003] Traditional spraying methods, such as manual backpack sprayers, are labor-intensive, inefficient, and prone to uneven application due to the instability of manual operation. While large self-propelled sprayers offer higher efficiency, they suffer from several drawbacks: first, their bulky size can easily crush seedlings in the early stages of wheat and corn growth; second, they struggle to adjust spray height and angle flexibly under varying crop heights and complex terrain conditions, hindering precision spraying and leading to pesticide waste and environmental pollution; and third, most existing equipment is designed for single crops or specific growth stages, failing to meet the diverse needs of wheat and corn throughout their entire growth cycle.

[0004] Based on this, a dual-track spraying device suitable for the entire growth period of wheat and maize is proposed. Summary of the Invention

The specific embodiments described herein are only used to explain the invention and are not intended to limit the invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] like Figure 1-8 As shown, the present invention provides a technical solution: a dual-track spraying device suitable for the entire growth period of wheat and corn, comprising a track unit 1, a walking unit 2, a lifting unit 3, a spraying box 4, and a spraying unit 5; The track unit 1 consists of two I-shaped tracks, which are installed in the planting field to be sprayed; the walking unit 2 is a self-driven walking platform, which is connected to the track unit 1; the mounting end of the lifting unit 3 is connected to the walking unit 2; the spraying tank 4 contains spraying liquid, which is installed on the top of the lifting unit 3; the spraying unit 5 is connected to multiple nozzles 57, which spray the liquid from the spraying tank 4 to complete the spraying operation.

[0021] By installing a track unit consisting of two I-shaped tracks in the wheat or corn planting field and setting the walking unit on the track unit, the walking unit can be stably operated in the planting field based on the double track structure. The height of the spraying can be roughly adjusted through the lifting unit 3, and the type of pesticide and the specific spraying method can be controlled through the pesticide tank 4 and the spraying unit 5, thus meeting the spraying needs of wheat and corn throughout the entire growth period, which is convenient and practical.

[0022] As one possible implementation method in this embodiment, the I-shaped track is composed of multiple track modules spliced ​​together. The upper flange of the I-shaped track is 12 cm wide, the lower flange is 15 cm wide, the web thickness is 2 cm, and the height is 10 cm.

[0023] The track spacing of the track unit 1 is 30-200cm to accommodate different planting row spacings.

Independently driven stirring rods 45 are rotatably connected to the front liquid medicine tank and the rear liquid medicine tank respectively. During use, two different types of liquid medicine can be placed in the front liquid medicine tank and the rear liquid medicine tank as needed. When spraying, the appropriate type of liquid medicine can be selected as needed to improve the spraying efficiency.

[0032] As one possible implementation method in this embodiment, the top of the liquid chamber 43 is provided with a liquid inlet 46, through which liquid can be added to the front liquid tank or the tail liquid tank respectively.

[0033] As one possible implementation method in this embodiment, a gate is provided in the lower middle section of the partition 44. When the gate is opened, the connection between the front medicine tank and the rear medicine tank can be completed.

The nozzle body 571 is provided with an obliquely arranged liquid delivery channel 575. A spherical connecting seat 572 is fixed at the tail end of the nozzle body 571. The nozzle body 571 is rotatably connected to the movable spray frame 52 or the fixed spray frame 53 through the spherical connecting seat 572. A cross-shaped connecting seat 573 is fixed in the liquid delivery channel 575. A liquid delivery turbine 574 is connected to the cross-shaped connecting seat 573. The liquid delivery turbine 574 can blow the liquid into the liquid delivery channel 575. The front end of the nozzle body 571 is equipped with a spray end head 576, and a control valve 578 is installed inside the spray end head 576. The control valve 578 controls the opening and closing between the spray end head 576 and the liquid delivery channel 575. Multiple spray through holes 577 are opened at equal intervals on the spray end head 576. When the control valve 578 is opened, the liquid delivery turbine 574 is activated. The liquid delivery turbine 574 can accelerate the liquid into the liquid delivery channel 575 and spray it out through the spraying hole 577 to complete the liquid spraying operation.

[0036] As one possible implementation of this embodiment, the movable sprayer 52 and the fixed sprayer 53 are respectively provided with a bottom horizontal working area 54, a vertical working area 55 and a top horizontal working area 56, and at least two nozzles 57 are connected to each of the bottom horizontal working area 54, the vertical working area 55 and the top horizontal working area 56.

[0037] When in use, after making a rough adjustment of the spraying height of the spraying box 4 using the cross-type lifting rod 32, lock the height of the cross-type lifting rod 32, and then select different work areas according to the type of liquid and the spraying height. When spraying pesticides on wheat or corn at a lower position, select the bottom horizontal working area 54 on the movable sprayer 52 or the fixed sprayer 53, and select an appropriate number of nozzles 57 according to the amount of pesticide to be sprayed, and carry out horizontal single or multiple spraying operations. When spraying wheat or corn at a higher position, select the top horizontal working area 56 on the movable sprayer 52 or the fixed sprayer 53, and select an appropriate number of nozzles 57 according to the amount of pesticide to carry out horizontal single or multiple spraying operations. When multiple vertical spraying operations are required, select the vertical working area 55 on the movable spraying frame 52 or the fixed spraying frame 53, and select an appropriate number of nozzles 57 according to the amount of pesticide to carry out single or multiple vertical spraying operations. By selecting the nozzles 57 in the bottom horizontal working area 54, vertical working area 55, or top horizontal working area 56 of the movable sprayer 52 or the fixed sprayer 53, different spraying operation modes can be completed, which is efficient and convenient.
