[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-Figure 5 The present invention provides a self-propelled spray boom 3 sprayer anti-herbicide drift device based on a corn-soybean strip composite planting mode, comprising:

[0033] A spliced ​​outer frame 1, wherein a plurality of partition frames 2 are detachably connected to the spliced ​​outer frame 1, and the plurality of partition frames 2 are divided into a plurality of spray zones in the spliced ​​outer frame 1;

[0034] The inner diameter of the square tube 5 is 18×18 mm, and the wall thickness is 2 mm; the number of the overall structure square tubes 5 is 26, 12 of which are 830 mm long, 4 are 900 mm long, 4 are 700 mm long, 2 are 1260 mm long, and 4 are 570 mm long (2 of which are punched in the middle with a hole diameter of 8 mm for connecting angle steel);

[0035] Cover cloth: the outside of the spliced ​​outer frame 1 and the plurality of partition frames 2 are covered with cover cloth respectively, and the bottom of the cover cloth on the spliced ​​outer frame 1 is flush with the bottom of the spliced ​​outer frame 1;

[0036] The spliced ​​outer frame 1 is composed of 26 detachably connected square tubes 5 and 16 square tube connectors 6;

[0037] The cover cloth is covered on the spliced ​​outer frame 1, the bottom of the cover cloth is flush with the bottom of the spliced ​​outer frame 1, and the cover cloth is spliced ​​with Oxford cloth according to the size of the spliced ​​outer frame 1;

[0038] The selection of the material of the cloth cover needs to consider its waterproofness, wear resistance and corrosion resistance to ensure that it can effectively prevent water from rubbing against crops when the machine is working outdoors, and that it can be durable.

[0039] The herbicide spraying assembly includes a spray rod 3 fixedly connected to the spliced ​​outer frame 1, and a plurality of adjustable spray heads 4 and a quick-insert elbow are installed on the spray rod 3. One end of the quick-insert elbow is connected to the spray rod 3, and the other end is connected to the medicine supply pipe;

[0040] The design of the spray boom 3 should take into account the flow and pressure of the pesticide, as well as the interface matching with the sprayer tank;

[0041] The spliced ​​outer frame 1 is detachably connected to the front end of the self-propelled sprayer, and a gap is provided between the frame and the ground.

[0042] According to a further optimization scheme, the spliced ​​outer frame 1 includes a plurality of square tubes 5 and square tube connectors 6. The plurality of square tubes 5 are spliced ​​together through the square tube connectors 6 to form a three-dimensional frame, and the longitudinal section of the three-dimensional frame is a trapezoidal structure.

[0043] A further optimized solution is that the square tube connector 6 is plugged into the square tube 5 , a positioning screw is installed on the square tube connector 6 , and the positioning screw passes through the square tube connector 6 and is fixed to the square tube 5 .

[0044] The square tube connector 6 is formed in two forms by welding a square sleeve, including 12 three-way galvanized connectors and 4 four-way galvanized connectors, which respectively cooperate with the square tubes 5 in three directions of the three-dimensional frame. The setting of the square tube connector 6 ensures that the connection between the pipes is tight and firm, so that the entire frame structure has excellent stability and load-bearing capacity. Whether it is subjected to static loads or dynamic impacts, it can maintain good performance and provide safe and reliable support for mechanical operations. Moreover, the components of the frame are all made of galvanized iron, which reduces costs, is beneficial to the corrosion protection of the metal frame, and increases the service life. At the same time, the size of the overall structure can be adjusted according to actual needs, and the device is more flexible.

[0045] In a further optimized solution, the shape of the partition frame 2 is adapted to the longitudinal cross-sectional shape of the spliced ​​outer frame 1. The longitudinal cross-sectional trapezoidal structure of the spliced ​​outer frame 1 has a top side length of 570 mm, a bottom side length of 1260 mm, and side side lengths of 900 mm and 700 mm, respectively.

[0046] According to a further optimization scheme, a galvanized angle steel 7 is fixedly connected to the spliced ​​outer frame 1, and the spray rod 3 is fixed in the spliced ​​outer frame 1 through the galvanized angle steel 7. The side width of the galvanized angle steel 7 is 30 mm, the side thickness is 6 mm, and the length is 450 mm.

[0047] Three holes with a diameter of 8 mm are punched on both sides of the galvanized angle steel 7. The upper hole is connected to the self-propelled spray boom sprayer, the middle hole is connected to the spliced ​​outer frame 1, and the lower hole is connected to the fixing part of the fixed spray boom 3, all of which are connected by hexagonal screws and matching nuts.

[0048] According to a further optimized solution, the length of the spray bar 3 is 400-2100 mm. The spray bar 3 is fixed on the galvanized angle steel 7 by a fixing member. The length of the spray bar 3 is 2100 mm, the diameter is 35 mm, and the aperture is 15 mm.

[0049] According to a further optimization scheme, the number of the adjustable nozzles 4 is 2-6. The number of the adjustable atomizing nozzles is 6, and the distance between adjacent adjustable atomizing nozzles is 400 mm.

[0050] A further optimized solution is that the spray rod 3 is fixed to the galvanized angle steel 7 by a fixing part. The fixing part includes a sleeve and a connecting pad. The connecting pad is fixed to the outer wall of the sleeve. The sleeve is sleeved on the outer wall of the spray rod 3, and a positioning bolt is threadedly connected to the sleeve. The positioning bolt is abutted against the spray rod 3, and the inner diameter of the sleeve matches the outer diameter of the spray rod 3; the inner diameter of the fixing part 3 is 35 mm, the sleeve height is 30 mm, the wall thickness is 2 mm, and the inner diameter of the upper hole is 8 mm.

[0051] In the present embodiment, it should be noted that due to the large difference in height between soybeans and corn, in the present embodiment, the rear end of the spray section corresponding to the corn spray section sets the straight square rod to a U-shaped structure, that is, a reserved channel for the corn, and a height-adjustable shielding cloth is set on the channel part, and a winding assembly is set on the external splicing frame, and a cover cloth is wound on the winding assembly, and a track is set on the square rod, and the end of the cover cloth is fixed by a slider and slid on the track, and a lead screw structure is used between the slider and the track for manual adjustment to achieve the spray rod being set on both sides of the corn in a relative manner. The side spraying method is combined with the channel setting to achieve spraying while avoiding the device from affecting the corn stalks during the spraying process.

[0052] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0053] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
