[0024] Firstly, the storage tank 2 is filled with an appropriate amount of pesticide, then the whole spraying machine is moved to the corn field that needs to be sprayed by connecting the traction member 101 with the traction equipment (such as a tractor), and the movable wheels 3 and the supporting wheels 10 provide good mobility and stability during the movement, according to the height and density of the corn plants, the spraying range of the spray head 803 needs to be adjusted, at this time, the double thread screw rod 501 can be rotated, since the two driving blocks 6 are symmetrically screwed on the outside of the double thread screw rod 501, when the double thread screw rod 501 rotates, the two driving blocks 6 will move towards or away from each other along the adjusting frame 5, and this movement drives the adjusting plate 8 connected at the top to rotate synchronously, thereby changing the spraying range of the spray head 803, and according to the height of the corn plants, the spraying height of the spray head 803 also needs to be adjusted, which can be achieved by rotating the rotating screw rod 703 inside the vertical frame 7, the rotating screw rod 703 is externally threaded with a transmission block 701, when the rotating screw rod 703 rotates, the transmission block 701 will move up and down along the rotating screw rod 703, and the limiting column 702 fixedly connected to one side of the transmission block 701 towards the adjusting plate 8 will also move, since the limiting column 702 is located in the limiting groove 804 inside the two adjusting plates 8, the movement of the limiting column 702 will drive the adjusting plate 8 to rotate around the rotating connection point at the top of the adjusting plate 8, thereby changing the spraying height of the spray head 803, when the spraying range and height are adjusted, the spraying pump 4 can be started, the spraying pump 4 draws pesticide from the storage tank 2 through the first conduit, and then delivers the pesticide to the two spray heads 803 through the second conduit and the third conduit respectively for spraying;

[0025] Through the design of the double thread screw rod 501 and the rotating screw rod 703, flexible adjustment of the spray head 803 in the horizontal and vertical directions is achieved, which makes the spraying machine adapt to corn plants of different heights and densities, ensures that the pesticide can uniformly cover the target area, and through precise control of the spraying range and height, the utility model reduces the waste and excessive spraying of pesticides, which helps to reduce environmental pollution.

[0026] In the embodiment, one end of the adjusting plate 8 is provided with a spraying part 801, the included angle between the spraying part 801 and the adjusting plate 8 is one hundred and sixty degrees, the bottom of the spraying part 801 is provided with a connecting frame 802, the spray head 803 is clamped in the inside of the connecting frame 802, the outside of the spray head 803 is provided with a connecting cover 9, the first spraying groove 902 is opened in the bottom of the connecting cover 9 directly below the spray head 803, the sealing cap 901 is clamped in the inside of the first spraying groove 902, a plurality of second spraying holes 903 are arranged on the side of the connecting cover 9 towards the adjusting plate 8, and the second spraying holes 903 occupy three fifths of the annular area of the sealing cap 901;

[0027] When spraying smaller plants, the spraying part 801 is parallel to the ground, at this time the sealing cap 901 is removed, and then the smaller plants can be sprayed through the first spraying groove 902. Due to inertia, the pesticide will not enter the second spraying hole 903. Due to the limited diameter of the first spraying groove 902, the pesticide can be accurately sprayed on the plants, avoiding waste. When spraying taller plants, one end of the adjusting plate 8 will tilt upward. At this time, the spraying part 801 is inclined, and the sealing cap 901 blocks the first spraying groove 902. After the sealing cap 901 blocks the first spraying groove 902, the spraying path of the pesticide is redirected to the second spraying hole 903 on the connecting cover 9. Since the second spraying hole 903 is distributed in a ring shape on the connecting cover 9, and its distribution area occupies three-fifths of the ring-shaped area of the sealing cap 901, the pesticide can be uniformly sprayed to the taller plants through the second spraying hole 903 facing the adjusting plate 8;

[0028] During the spraying process, as the inclination angle of the adjusting plate 8 is adjusted, the height and angle of the spray head 803 relative to the plants also change accordingly. This change ensures that the pesticide can accurately cover all parts of the plants, whether it is the front or back of the leaves, and can be fully protected. At the same time, due to the number and distribution of the second spraying hole 903, even when spraying at a high angle, the uniform distribution of the pesticide can be ensured, avoiding local over-concentration or dilution;

[0029] The design of the sealing cap 901 not only serves as a switch for the spraying path, but also protects the first spraying groove 902 from contamination by debris and dust when not in use. When it is necessary to switch back to using the first spraying groove 902 for low plant spraying, simply remove the sealing cap 901. The operation is convenient and efficient.

[0030] The utility model discloses a working principle and use flow: first, first, fill the storage box 2 with the pesticide of proper amount, then, through the traction piece 101 is connected with the traction equipment (for example tractor), the whole spraying machine is moved to the corn field that needs to be sprayed, in the moving process, the caster 3 and the support wheel 10 provide good mobility and stability, according to the height and density of corn plant, need to adjust the spraying range of the spray head 803, at this moment, can rotate double thread screw rod 501, because two drive blocks 6 symmetrical screw connection in the outside of double thread screw rod 501, when double thread screw rod 501 rotates, two drive blocks 6 will along with the adjustment frame 5 move towards or move away, this kind of movement drives the adjustment plate 8 of top swing joint synchronous movement, thereby changed the spraying range of the spray head 803, also need to adjust the spraying height of the spray head 803 according to the height of corn plant, this can be realized through rotating the rotating screw rod 703 in the vertical frame 7, the rotating screw rod 703 is externally threaded and has a transmission block 701, when the rotating screw rod 703 rotates, the transmission block 701 will along with the rotating screw rod 703 moves up and down, the limit post 702 fixedly connected on the one side of transmission block 701 towards the adjustment plate 8 also moves along with it, because the limit post 702 is located in the limiting groove 804 in the inside of two adjustment plates 8, thus the movement of limit post 702 will drive the adjustment plate 8 rotates around its top swing joint point, thereby change the spraying height of the spray head 803, when the spraying range and height are adjusted, can start the spraying pump 4, the spraying pump 4 draws the pesticide from the storage box 2 through the first conduit, then through the second conduit and the third conduit respectively the pesticide is delivered to two spray heads 803 and is sprayed, when the smaller plant is sprayed, the spraying part 801 is parallel to the ground, at this moment, the sealing cap 901 is removed, and then the smaller plant can be sprayed through the first spraying groove 902, because the inertia pesticide will not enter the second spraying hole 903, because the diameter of the first spraying groove 902 is limited, so that the pesticide can be accurately sprayed on the plant, avoid waste, when the higher plant is sprayed, one end of the adjustment plate 8 will be inclined to rise, at this moment, the spraying part 801 is inclined, and the first spraying groove 902 is blocked by the sealing cap 901, when the first spraying groove 902 is blocked by the sealing cap 901, the spraying path of the pesticide is redirected to the second spraying hole 903 on the connecting cover 9, because the second spraying hole 903 is annularly distributed on the connecting cover 9, and the distribution area occupies three fifths of the annular area of the sealing cap 901, the pesticide can be evenly sprayed to the higher plant through the second spraying hole 903 towards the adjustment plate 8, in the spraying process, with the inclination angle adjustment of the adjustment plate 8, the height and angle of the spray head 803 relative to the plant also change accordingly, this change ensures that the pesticide can accurately cover each part of the plant, whether it is the front or back of the leaf, can be fully protected, at the same time, because the number and distribution of the second spraying hole 903, even in high-angle spraying, can also ensure the uniform distribution of the pesticide, avoid local over-concentration or dilution.
