Technical Field
[0001] The present invention belongs to the technical field of rapeseed hybridization, and specifically relates to a precise spraying device for a rapeseed hybridization agent. Background Art
[0002] Rapeseed is an important oilseed crop in my country, and hybrid breeding technology is crucial for improving yield and quality. However, traditional rapeseed hybrid seed production is plagued by issues such as imprecise application of hybridizing agents, unstable efficacy, and environmental pollution, resulting in low hybrid seed purity and high production costs.
[0003] Rapeseed seed production generally requires planting 1-2 rows of male parents and 2-10 rows of female parents. Traditional application methods (such as manual spraying or large-scale mechanical spraying) make it difficult to precisely control the amount and placement of the hybridizing agent. This can result in some female plants not receiving effective treatment or excessive application, which can damage the male parent and affect hybridization results. Environmental factors (such as wind speed and temperature) and improper application techniques can easily lead to uneven distribution of the hybridizing agent across the plants, reducing the induction rate of sterile plants. Furthermore, manual application is inefficient, with large spraying errors and high labor intensity, making it difficult to meet the needs of large-scale hybrid seed production.
[0004] At present, there is a need for a pesticide application device that can spray rapeseed flowers accurately and stably. Therefore, a stable and accurate pesticide application device for rapeseed hybrid agent is proposed. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention realizes the function of actively adapting to and adjusting the rapeseed row width through the walking mechanism and the mother parent positioning mechanism. The user can control the power motor to work through the electrical control panel to drive the walking wheel to rotate, thereby moving the device to the seed rapeseed field. Then, the user can again control the positioning telescopic rod and the gap telescopic rod to work through the electrical control panel to drive the adjustment frame to slide on the positioning track. According to the actual planting row width, the user can adjust the position of the adjustment frame so that it is located directly above the rapeseed mother parent row. This design effectively solves the problem of the existing technology that is difficult to adapt to irregular row widths, and improves the adaptability and flexibility of the present device. (2) The present invention is provided with an adaptive protection mechanism, which achieves the effect of isolating the male and female rapeseed plants, and controls the extension of the protective hydraulics on both sides. In the initial state, due to the self-gravity of the protective arc plate and the folding arc plate, the protective arc plate exerts a pulling force on the protective hydraulics, and the folding arc plate is in a vertical state. When the protective hydraulics are extended, they are always subjected to the pulling force of the protective arc plate, causing the protective arc plate to rotate on the side wall of the adjustment frame. During the rotation process, the sequential slider and the protective arc plate remain relatively stationary. The folding arc plate tends to maintain a vertical state due to its own gravity, thereby rotating on the side wall of the protective arc plate and vertically inserting downward between the two rows of rapeseed. When the protective arc plate rotates When the folding plate moves to the maximum angle and is limited by the adjustment frame, the folding rod on the folding arc plate contacts the sequential slider, the protective hydraulic device continues to extend, and the sequential slider is pushed to slide on the inner wall of the folding groove, compressing the sequential spring, and at the same time pushing the folding rod to drive the folding arc plate to rotate, wrapping the rapeseed flowers. The rotation angle of the folding plate is determined according to the actual growth conditions of the rapeseed, which effectively solves the problem of spraying hybridization agents to contaminate the male parent in the prior art and greatly improves the seed production efficiency. When the spraying is finished, the protective hydraulic device is retracted, the sequential spring returns to its initial state, the folding arc plate returns to its vertical state, and the protective arc plate rotates to remove the folding arc plate vertically upward to avoid damaging the rapeseed. (3) The present invention designs a pumping system to achieve quantitative and fixed-point application of pesticides. By controlling the operation of the liquid pump, the hybridizing agent in the hybridizing agent box can be sent to each branch of the application pipe through the application main pipe and sprayed on the rapeseed flowers. The user can control the flow rate of each row through the electric control valve to achieve precise quantitative application of the hybridizing agent, reducing the error caused by human labor; (4) The present invention is provided with a uniform spraying mechanism to achieve precise spraying. The control cycle servo motor rotates, and the power sprocket and the transmission sprocket drive the chain to rotate, and then drive the sliding frame and the sliding rod on the side wall of the chain to rotate. Since the side wall of the sliding rod slides on the inner wall of the sliding groove in the shape of a bent circle, the sliding rod can be driven to move up and down with the sliding groove during the rotation process, maintaining a constant distance from the rapeseed flower, avoiding uneven spraying due to uneven height. At the same time, the sliding rod drives the rotating nozzle to rotate, and circulates the spraying above the rapeseed flower, effectively solving the problem caused by nozzle blockage. To solve the problem of uneven spraying, when the sliding rod rotates to the arc of the sliding groove, the rotating rod contacts the folding block. As the sliding rod rotates further, the distance between the sliding rod and the folding block is shortened, pushing the rotating rod to rotate at the bottom end of the sliding rod, driving the rotating nozzle to rotate, and adjusting the angle to face the rapeseed flowers, so that the nozzle can rotate cyclically and aim at the rapeseed flowers, solving the problem of uneven spraying caused by different spraying angles in the existing technology. The rotating manifold transmits the hybridizing agent and rotates at the bottom end of the spraying branch pipe at the same time to prevent the pipe from being entangled. The side nozzles on the protective arc plate spray the flowers on both sides of the rapeseed, thereby increasing the receiving surface. (5) The present invention is also equipped with a dual-channel reflux mechanism, which realizes the recycling of liquid medicine and the isolation of agent spraying. During the spraying process, part of the hybridizing agent sprayed from above will float in the air, and part will condense into droplets and fall to the soil below. At this time, the reflux fan can be controlled by the electrical control panel to generate negative pressure in the reflux pipe and the collection opening pipe. The droplets of hybridizing agent falling to the soil below enter from one end of the bell mouth of the collection opening pipe. The hybridizing agent floating in the air is sucked in by the reflux pipes on both sides of the folded arc plate and blown to the rapeseed flowers through the secondary circulation pipe, realizing the recycling of liquid medicine and ensuring that the hybridizing agent will not float to the adjacent rows, effectively solving the problem of the male parent being contaminated by the application of pesticides in the prior art.

[0029] The chain 425 is engaged with the power sprocket 423 and the transmission sprocket 424 .
[0030] Among them, the sliding groove 426 is in a bent circular shape, the main spraying pipe 413 is a PVC hard pipe, the spraying branch pipe 414 is a hose, the small end of the collecting opening pipe 501 is a hose, and the protective arc plate 321 and the folding arc plate 323 are made of plastic.
[0031] During specific use, the default hybridization agent box 411 is filled with hybridization agent. First, the user can control the power servo motor to work through the electrical control panel 101, thereby driving the walking wheel 201 to rotate, and then control the movement of the device to move the device to the seed rapeseed field. Then, the user can control the positioning telescopic rod 313 and the gap telescopic rod 314 to work through the electrical control panel 101, thereby driving the adjustment frame 312 to slide on the positioning track 311. At this time, the user can adjust the position of the adjustment frame 312 according to the actual planting row width, so that each adjustment frame 312 is located directly above the rapeseed mother row, thereby achieving the technical effect of actively adapting to the rapeseed row width, effectively solving the technical problem that the existing technology is difficult to adapt to irregular row widths, and improving the adaptability and flexibility of the device; Then the user can control the height hydraulic machine 203 through the electrical control panel 101, and then control the height of the main frame 1, and then drive the adjustment frame 312 to be adaptively located 15 cm above the rapeseed, ensuring the spraying effect, and achieving the technical effect of adapting to the actual height of rapeseed and different varieties. Then the user can control the protection hydraulic machine 322 on both sides to extend through the electrical control panel 101. At this time, the sequence spring 327 will generate a thrust on the sequence slider 326 due to the compression elastic force. When the protection hydraulic machine 322 is extended, in the initial state, due to the protection arc Due to the gravity of the plate 321 and the folding arc plate 323, the protective arc plate 321 exerts a pulling force on the protective hydraulic press 322, and the folding arc plate 323 is in a vertical state. When the protective hydraulic press 322 is extended, the protective hydraulic press 322 is always pulled by the protective arc plate 321, thereby causing the protective arc plate 321 to rotate on the side wall of the adjustment frame 312. During the rotation process, the sequential slider 326 and the protective arc plate 321 remain relatively stationary, while the folding arc plate 323 is affected by its own gravity and tends to remain in a vertical state, thereby enabling The folding arc plate 323 is rotated on the side wall of the protective arc plate 321, and the folding arc plate 323 can be vertically inserted downward between the two rows of rapeseed. When the protective arc plate 321 is rotated to the maximum angle, it is limited by the adjustment frame 312. At this time, the folding rod 324 on the folding arc plate 323 will contact the sequential slider 326. At this time, the protective hydraulic press 322 continues to extend. Since the adjustment frame 312 cannot rotate, it will push the sequential slider 326 to slide on the inner wall of the folding groove 325, thereby compressing the sequential spring 327 and pushing the folding rod 324 at the same time, thereby The movable folding arc plate 323 rotates to wrap the rape flowers. The specific rotation angle of the folding plate is based on the actual growth conditions of the rape, thereby achieving the effect of isolating the male and female rape plants, effectively solving the technical problem of spraying hybridization agents to contaminate the male parent in the prior art, and greatly improving the seed production efficiency. When the spraying is completed, the protective hydraulic actuator 322 can be retracted. At this time, the sequence spring 327 first returns to the initial state, that is, the folding arc plate 323 returns to the vertical state, and the protective arc plate 321 rotates, and the folding arc plate 323 can be taken out vertically to avoid damaging the rape. The user can then control the operation of the liquid pump 412 through the electrical control panel 101, thereby allowing the hybridizing agent in the hybridizing agent box 411 to enter the various application branches 414 through the application main pipe 413 and then be sprayed on the rapeseed flowers. The user can control the flow rate of each row through the electric control valve 415, thereby achieving precise quantitative application of the hybridizing agent, achieving the technical effect of quantitative and fixed-point application, and reducing errors caused by human factors. Then the user can control the circulation servo motor 422 to rotate through the electrical control panel 101, which is transmitted through the power sprocket 423 and the transmission sprocket 424, so that the chain 425 can rotate, and then the sliding frame 427 on the side wall of the chain 425 can be driven to rotate, thereby driving the sliding rod 428 to rotate. Since the side wall of the sliding rod 428 slides on the inner wall of the sliding groove 426, and the sliding groove 426 is a bent circle, during the rotation process, the sliding rod 428 can be driven to move up and down following the sliding groove 426, thereby achieving the technical effect of maintaining a constant distance from the rapeseed flower, avoiding uneven spraying due to uneven height. At the same time, the sliding rod 428 drives the rotating nozzle 4211 to rotate, so that the rotating nozzle 4211 can circulate and spray above the rapeseed flower, effectively solving the technical problem of uneven spraying due to nozzle blockage, and achieving precise control. The technical effect of accurate spraying is that when the sliding rod 428 rotates to the arc of the sliding groove 426, the rotating rod 429 will contact the folding block 4212. With further rotation, the distance between the sliding rod 428 and the folding block 4212 will be shortened, thereby pushing the rotating rod 429 to rotate at the bottom end of the sliding rod 428, thereby driving the rotating nozzle 4211 to rotate, and adjusting the angle of the rotating nozzle 4211 to face the rapeseed flower, thereby achieving the technical effect of circulating the nozzle and aiming at the rapeseed flower, effectively solving the technical problem of uneven spraying due to different spraying angles in the prior art, and at the same time rotating the manifold 4210 to transmit the hybridizing agent, and rotating the manifold 4210 simultaneously rotates at the bottom end of the pesticide branch pipe 414 to prevent the pipe from being entangled, and the side nozzles 421 on the protective arc plate 321 will spray the flowers on both sides of the rapeseed, thereby increasing the receiving surface; During the spraying process, part of the hybridizing agent sprayed above will float in the air, and part will condense into droplets and fall to the soil below. At this time, the return fan 503 can be controlled by the electrical control panel 101, and negative pressure will be generated in the return pipe 502 and the collection opening pipe 501. The hybridizing agent droplets falling to the soil below will enter from the trumpet end of the collection opening pipe 501, and the hybridizing agent floating in the air will be sucked in by the return pipe 502 on both sides of the folding arc plate 323, and blown to the rapeseed flowers through the secondary circulation pipe 504, realizing the technical effect of recycling the liquid medicine, and at the same time ensuring that the hybridizing agent will not drift to adjacent rows, thereby achieving the technical effect of spraying isolation of the medicine, and effectively solving the technical problem of the application of pesticides to contaminate the father in the prior art.
