Description

Technical Field

[0001] The invention relates to the technical field of agricultural breeding spraying, and in particular to a sorghum leaf spraying device for nitrogen fertilizer and melatonin. Background Art

[0002] my country has a vast territory and many farmlands prone to waterlogging. Although sorghum has a certain degree of waterlogging resistance, there are differences in waterlogging resistance between different sorghum varieties. After waterlogging, the active oxygen content in sorghum leaves increases, and the chloroplast structure is damaged, which seriously affects the photosynthesis and normal physiological processes of sorghum.

[0003] Studies have shown that melatonin can effectively reduce the accumulation of reactive oxygen in plants under adverse stress and alleviate the damage of reactive oxygen to leaves. The combined use of melatonin and nitrogen fertilizer, as well as the combined use of melatonin and urea are better than using either alone.

[0004] In the prior art, when spraying pesticides or applying fertilizers on a larger area of ​​farmland, drones are used to improve work efficiency. Although drone operations can improve efficiency, there are many environmental restrictions and the spraying or application effect of pesticides is easily affected by weather and wind direction.

[0005] Although the hand-operated sprayer is conducive to controlling the precise spraying range, it is inefficient and labor-intensive during operation, and is not suitable for large-scale operations. Usually, the user carries the liquid tank while walking to spray, which increases the user's load.

[0006] Moreover, the liquid tanks of drones or hand-cranked sprayers are usually static storage, which is not conducive to the storage of mixed liquid medicines. Especially during long-term operations, liquid medicines are prone to precipitation, thus affecting the spraying effect. Although they can be mixed during the spraying process through an agitator, it not only increases the equipment cost, but also further increases the weight of the device, which is not conducive to the spraying operation.

[0045] like Figure 1 and Figure 4 As shown, the present invention provides a sorghum foliar spraying device for nitrogen fertilizer and melatonin, comprising a liquid storage cylinder 10, on which at least one set of tires 11 is fixedly arranged, the length direction of the liquid storage cylinder 10 penetrates the inside of the tires 11 to form an integrated structure, and the tires 11 are movably abutted against the ground to form a self-rotating structure;

[0057] The spray pipe 30 is rotatably connected to the liquid storage cylinder 10 through a rotary joint 31, so that the liquid storage cylinder 10 keeps the spray pipe 30 at the same angle for spraying during the rolling process;

[0058] The spray pipe 30 is wound around the cross bar 323 and connected to the medicine pump 36, and then connected to the straight spray pipe 33 and the oblique spray pipe 34 through the three-way head 35, so as to achieve the purpose of multi-angle spraying. Multi-angle spraying is performed through the straight spray pipe 33 and the oblique spray pipe 34 to expand the spraying range, and a plurality of atomizing nozzles 37 are arranged at equal intervals on the straight spray pipe 33 and the oblique spray pipe 34, which is conducive to achieving the purpose of three-dimensional uniform spraying and improving the spraying efficiency.

[0059] like Figure 1 , Figure 2 and Figure 5 As shown, one end of the movable screw 322 passes through the inner wall of the fixed tube 321, and a movable groove 324 is provided on one side of the fixed tube 321 close to the cross bar 323, the cross bar 323 is meshed and connected with the movable screw 322 through the movable groove 324, and a thread matching the movable screw 322 is provided on the outer wall of the cross bar 323;

[0060] A rotating motor 23 fixedly mounted on the frame 20 is provided at one end of the cross bar 323. After the cross bar 323 rotates around the connection between it and the rotating motor 23, it engages with the movable screw 322 and moves along the length direction to form a height adjustment structure, and the spray pipe 30 rotates around the winding position between it and the cross bar 323 to form a retracting structure.

[0061] The motor 23 is rotated to drive the crossbar 323 to rotate, and the crossbar 323 drives the movable screw 322 to slide in the fixed pipe 321 through engagement, and further drives the straight spray pipe 33 and the oblique spray pipe 34 to rise and fall at the top of the movable screw 322, so as to achieve the purpose of adjusting the spraying height.

[0062] The motor 23 is rotated to drive the crossbar 323 to rotate, and the crossbar 323 drives the movable screw 322 to slide in the fixed pipe 321 through engagement, and further drives the straight spray pipe 33 and the oblique spray pipe 34 to rise and fall at the top of the movable screw 322, so as to achieve the purpose of adjusting the spraying height.

[0063] like Figure 3 and Figure 4 As shown, the liquid storage cylinder 10 is provided with an outer cylinder 101, the outer cylinder 101 is hollow and forms a double-layer heat-insulating structure with the liquid storage cylinder 10, and a water inlet 102 is provided on one side of the outer cylinder 101;

[0064] A feeding mechanism 13 is provided on the liquid storage cylinder 10, a premixing cylinder 14 is provided on the feeding mechanism 13, and a feeding pipe 103 is provided on the liquid storage cylinder 10. The premixing cylinder 14 is built into the liquid storage cylinder 10 and connected to the feeding pipe 103 to form a two-stage feeding structure, and liquid and powder respectively enter the premixing cylinder 14 to form a premixing structure.

[0065] An outer cylinder 101 is used to provide protection outside the liquid storage cylinder 10, thereby improving the light-shielding and heat-insulating effects inside the liquid storage cylinder 10. At the same time, a cavity is formed in the outer cylinder 101, and liquid can be filled into the cavity inside the outer cylinder 101 through the water inlet 102 to achieve the purpose of enhancing the heat-insulating effect, thereby better storing the mixed liquid of nitrogen fertilizer and melatonin and reducing the effects of factors such as sunlight and temperature that affect the melatonin effect.

[0066] By connecting the premixing cylinder 14 to the feeding mechanism 13, melatonin powder can be stored separately while part of the melatonin can be dissolved and mixed during the movement of the device, thereby facilitating the improvement of the mixing efficiency and uniformity of melatonin and nitrogen fertilizer during the next replenishment.

[0067] like Figure 3 and Figure 4 As shown, a disturbance member 12 is provided on the liquid storage cylinder 10, and the disturbance member 12 rotates around the center of the liquid storage cylinder 10 to form a disturbance structure;

[0068] The disturbance member 12 includes a support rod 121, an axis rod 122, an elastic rope 123 and a friction ball 124.

The outer wall of the axis rod 122 is movably provided with a ring 125, and the ring 125 is provided with at least two groups of friction balls 124 through the elastic rope 123.

[0069] In the liquid storage cylinder 10 , the flow velocity of the liquid medicine in the liquid storage cylinder 10 is increased by the disturbance member 12 , thereby slowing down the sedimentation velocity of the liquid medicine and enhancing the mixing effect of the liquid medicine.

[0070] The shaft 122 is fixed by the support rod 121, so that the ring 125 rotates around the outside of the shaft 122, and the friction ball 124 is controlled to rotate around the axis of the liquid storage cylinder 10, thereby increasing the friction between the friction ball 124 and the inner wall of the liquid storage cylinder 10 and reducing the precipitation and adhesion of the liquid medicine.

[0071] like Figure 3 and Figure 7As shown, the feeding mechanism 13 includes a mixing barrel 131 and a stirring rod 132. The top end of the mixing barrel 131 is connected to the feeding pipe 103.

[0075] At the same time, when the liquid flows in the liquid storage cylinder 10, the disturbance piece 12 and the stirring rod 132 are driven to rotate, thereby enhancing the stirring of the medicine liquid. The rotation of the medicine liquid drives the disturbance piece 134 to rotate, driving the stirring rod 132 and the stirring piece 135 to rotate, thereby achieving the purpose of mixing the medicine liquid in the mixing cylinder 131, reducing the use of driving equipment, and achieving the purpose of reducing costs and improving work efficiency.

[0077] The baffle 24 has a lower baffle 242 and an upper baffle 243 disposed opposite to each other on the outer wall of the sleeve 241 , and the longitudinal section of the upper baffle 243 is an L-shaped structure.

[0078] The baffle plate 24 on the pull rod 21 isolates the user from the spraying range, thereby reducing the spray liquid from scattering onto the user, reducing the harm to the user, and improving the protection effect.

[0079] Through the combined extension and retraction of the fixed tube sleeve 211 and the fixed rod 213, it is convenient to rotate the pull rod 21 for steering, and at the same time, the baffle 24 is rotated to facilitate the two-way use angle. The L-shaped structure of the upper baffle 243 is conducive to expanding the shielding range and angle of the user and enhancing the protection effect.
