Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural planting equipment, in particular to a disease and pest spraying device for corn planting. BACKGROUND

[0002] During the growth of corn, it is easy to be threatened by various diseases and pests, such as corn borer, aphid, leaf spot disease, rust disease, etc., which seriously affect the yield and quality of corn. Therefore, scientific and timely spraying of pesticides is one of the key links of corn field management. Spraying pesticides on corn can reduce the occurrence of pests and achieve the effect of increasing the yield of corn planting.

[0003] Traditional spraying of pesticides on corn relies on manual backpack sprayers. The operator carries a pesticide storage tank on his back and holds a spray rod to operate. This method not only has high labor intensity and low operation efficiency, but also in the middle and late growth period of corn, the plant height can reach more than 2 meters, and the crown layer is dense, so it is difficult for manual spraying to cover the middle and upper leaves, resulting in poor control effect.

[0004] Due to the small distance of corn planting and the vertical growth of corn, the plant is tall in the middle and late growth period, and the ordinary spray rod cannot cover the middle and upper leaves, resulting in uneven spraying of pesticide mist when spraying pesticides on corn. In the prior art, there are large pesticide spraying equipment for spraying above the plants, but the lower part of the leaves is also not covered, which still leads to poor effect of spraying pesticides on corn. In addition, due to the limitation of operation mode and equipment, the traditional pesticide spraying has problems such as poor atomization effect of pesticide liquid, uneven coverage, serious drift and loss of pesticide liquid. Not only does it cause waste of pesticides and increase production cost, but also leads to environmental pollution, and even may cause crop pesticide damage.

Based on the examples in the present application, all other examples obtained by the ordinary skilled person in the art without creative labor belong to the scope of protection of the present application.

[0039] Example 1

[0040] A corn planting disease and pest spraying device, comprising a vehicle body 1, a cab 2, a pesticide spraying mechanism, a vertical lifting mechanism, a walking mechanism and an integrated power module 17. The vehicle body 1 is welded by high-strength lightweight alloy material, which has good corrosion resistance and structural stability.

[0041] A medicine box 3 is arranged in the vehicle body 1, and the volume of the medicine box 3 can be designed as 500-2000 liters according to actual operation requirements. An injection port 301 is arranged on the medicine box 3, and the medicine box 3 is connected with a medicine pump 4 through a corrosion-resistant pipeline. The medicine pump 4 adopts a diaphragm type or a plunger type structure, which is controlled by the control center 18 to start and stop and control the flow. The output flow can be steplessly adjusted by the control center 18, and the range is 10-100 liters / minute, so as to meet the required pesticide spraying amount of different disease and pest control. The pesticide is input into the medicine box 3 through the injection port 301, and the pesticide in the medicine box 3 is pumped out through the medicine pump 4.

[0042] The cab 2 is located at the front end of the vehicle body 1, and adopts a fully enclosed design, which has good sealing performance and wide field of vision. The control center 18 is arranged in the cab 2.

[0043] In an embodiment of the present application, the cab 2 is provided with sliding or outward opening doors 201 on both sides, and the doors 201 are equipped with safety locking devices. The cab 2 is provided with transparent windows 202 on both sides and the front side, and the window material can be selected from explosion-proof glass or polycarbonate material, which has anti-fog and anti-ultraviolet functions. The cab 2 is provided with an ergonomic driver's seat 19, the height and angle of which can be adjusted, and is equipped with a safety belt. The user opens the door 201 to enter the cab 2, sits on the driver's seat 19 to work, and the transparent window 202 is used to observe the forward travel route and working conditions. The control center 18 in the driver's seat 19 is integrated with a steering wheel, a braking system, a pesticide spraying control interface and a hydraulic lifting control interface, including a color touch screen, mechanical buttons, a steering wheel, a brake pedal, an accelerator pedal, a hydraulic control lever and a pesticide pump control module. The screen can display real-time information such as vehicle speed, pesticide pump 4 flow, hydraulic system pressure, battery capacity, fan state, support one-key start, fault diagnosis and operation data recording function, and the operation is simple.

[0044] The pesticide spraying mechanism includes front row pesticide spraying integrated pipe 5 and rear row pesticide spraying integrated pipe 7, and the front row pesticide spraying integrated pipe 5 and the rear row pesticide spraying integrated pipe 7 are communicated through the connecting pipe 6. The front row pesticide spraying integrated pipe 5 is provided with front spraying rods 8 longitudinally on both sides, and the front spraying rods 8 are inclined downward. The rear row pesticide spraying integrated pipe 7 is provided with rear spraying rods 9 longitudinally on both sides, and the rear spraying rods 9 are inclined upward. The front spraying rods 8 and the rear spraying rods 9 are bendable pipes made of stainless steel or engineering plastic, and can realize multi-angle adjustment. The downward inclination angle of the front spraying rods 8 is adjusted between 15°-45° to adapt to corn plants of different heights and densities. The upward inclination angle of the rear spraying rods 9 can be adjusted within the range of 10°-30°. The ends of the front spraying rods 8 and the rear spraying rods 9 are provided with spray heads 10. The spray heads are selected from fan-shaped mist spray heads or conical mist spray heads, and the droplet size range is controlled within 100-300 microns to ensure good adhesion and coverage of the pesticide liquid on the leaf surface. The front row pesticide spraying integrated pipe 5 is slightly higher than the rear row pesticide spraying integrated pipe 7, and the height difference can be adjusted according to the growth cycle of corn, usually within the range of 20-50 cm. The front row pesticide spraying integrated pipe 5 is used to cover the upper part of the leaf, and the rear row pesticide spraying integrated pipe 7 is used to cover the lower part of the leaf, forming comprehensive pesticide spraying coverage.

[0045] In an embodiment of the present application, the front row pesticide spraying integrated pipe 5 is mirror image provided with two groups, and the rear row pesticide spraying integrated pipe 7 is mirror image provided with two groups. They are respectively located on the left and right sides of the vehicle body, which is convenient for simultaneously spraying plants on both sides.

[0046] In an embodiment of the present application, the front row pesticide spraying integrated pipe 5 includes a telescopic spray pipe 501 connected with the output end of the pesticide pump 4, a front cross rod 502 and a front longitudinal rod 503 connected with each other. The telescopic spray pipe 501 is a bellows structure, which can be telescopic within a certain length range, providing a margin for the lifting adjustment of the pesticide spraying mechanism. The rear row pesticide spraying integrated pipe 7 includes a rear cross rod 701 and a rear longitudinal rod 702.

[0047] The vertical lifting mechanism is used to adjust the working height of the pesticide spraying mechanism to adapt to the change of plant height in different growth periods of corn. The vertical lifting mechanism includes a hydraulic cylinder 13 mounted on the vehicle body 1 and a support cylinder frame 11 sleeved outside the hydraulic cylinder 13. The hydraulic cylinder 13 can adopt a multi-stage telescopic oil cylinder with a stroke range of 1.5-3 meters and a lifting capacity of not less than 200 kilograms. The support cylinder frame 11 is made of square or circular steel pipes and the surface is treated by corrosion protection. The support cylinder frame 11 is provided with fixing plates 12 on the top front and rear sides for fixing the front row of pesticide spraying integrated pipes 5 and the rear row of pesticide spraying integrated pipes 7. The fixing plates 12 are designed to be adjustable, allowing fine adjustment of the position of the integrated pipes. The outer side of the support cylinder frame 11 is provided with a mounting bracket 14 on which an axial flow fan 15 cooperating with the front spray rod 8 and the rear spray rod 9 is mounted. The axial flow fan 15 is driven by a direct current brushless motor with a power of 1-3 kilowatts and a wind speed adjustable range of 5-20 meters / second. The hydraulic cylinder 13 and the axial flow fan 15 are controlled by a control center 18.

[0048] In an embodiment of the present application, the axial flow fan 15 is provided with four groups, and the air outlet of the axial flow fan 15 is provided with a flow guide cover. The central axis of the front row of axial flow fans 15 forms a 30-degree angle with the horizontal line to optimize airflow guidance and accurately blow pesticide mist to the target area. The axial flow fan 15 is used to help the sprayed pesticide mist to diffuse, increase the adhesion of pesticide liquid and reduce waste.

[0049] The walking mechanism is located below the vehicle body 1 and the cab 2.

[0050] In an embodiment of the present application, the walking mechanism includes high ground clearance wheels 20 mounted on the bottom of the vehicle body 1 and front wheels 22 mounted on the bottom of the cab 2. The high ground clearance wheels 20 are directly driven by a hub drive machine 21, and the power is provided by an integrated power module 17 to ensure smooth travel in the corn field. The hub drive machine 21 has a power of 5-15 kilowatts, large torque and wide speed regulation range, and supports forward, backward and stepless speed change. The front wheels 22 are steering wheels and adopt a hydraulic power-assisted steering system, which is flexible and light in steering. The high ground clearance wheels 20 have a diameter of 80-120 centimeters and an adjustable track to adapt to different row spacing requirements.

[0051] The integrated power module 17 is arranged at the rear of the vehicle body 1 and adopts a shockproof and waterproof design to provide power for the pesticide spraying mechanism, the vertical lifting mechanism and the walking mechanism. Specifically, it provides power for the pesticide pump 4, the hydraulic cylinder 13, the axial flow fan 15 and the hub drive machine 21 to support the whole vehicle operation function, and also can provide power for other auxiliary equipment of the control center 18. The integrated power module 17 is composed of a lithium battery pack or a diesel generator set, and the lithium battery capacity can be designed to be 30-100 kilowatt-hours according to the operation time requirement, supporting continuous operation for 4-8 hours.

[0052] When working, the operator fills the liquid medicine from the filling port 301, then enters the cab 2, fastens the safety belt, and starts the equipment through the control center 18. First, check whether each system state is normal, including battery power, hydraulic system pressure, medicine pump function, etc. Set the operation parameters, including travel speed, medicine pump flow, spray bar angle, and fan speed, etc.

[0053] The control center 18 controls the walking mechanism to move forward, and at the same time starts the medicine pump 4 to deliver the liquid medicine to the front and rear rows of the spray integrated pipe 5 and 7 and finally to the front and rear spray bars. According to the height of the corn, the overall height of the spray mechanism is adjusted through the hydraulic cylinder 13 to make the spray head in the best working position. The front spray bar 8 sprays downward to cover the upper leaves of the plant, and the rear spray bar 9 sprays upward to cover the lower leaves, realizing three-dimensional coverage. Four groups of axial flow fans 15 are started synchronously to generate directional airflow, further dispersing the pesticide mist and guiding it to the plant, enhancing the adhesion of the liquid medicine on the leaf surface and reducing the drift of the liquid medicine.

[0054] During the spraying operation, the operator can observe the operation effect through the transparent window 202, and if necessary, can adjust the parameters in real time through the control center 18. In case of emergency, the emergency stop button can be pressed immediately to cut off all power sources.

[0055] After completing the operation, first, close the medicine pump 4, and let the fan continue to run for a period of time to blow off the residual liquid medicine in the pipeline. Then, lower the spray mechanism to the lowest position, turn off the power, and clean and maintain the equipment. Open the blocking cover 16 at the bottom of the front and rear longitudinal rods 503 and 702, and flush the inside of the pipeline with clean water to prevent the liquid medicine from crystallizing and blocking the spray head 10. Regularly check the wear of the spray head 10 and replace the damaged parts in time.

[0056] The spraying device is particularly suitable for the prevention and control of pests and diseases in the middle and late growth stages of corn, and can effectively solve the problem of insufficient coverage of the upper leaves by traditional spraying devices, and improve the utilization rate of liquid medicine and the prevention and control effect. At the same time, its high ground clearance design and flexible adjustment capability make it able to adapt to the operation needs of corn fields in different growth stages and planting modes, and it is an indispensable professional plant protection equipment in modern corn planting.

[0057] Example 2:

[0058] This example is basically the same as example 1, the difference is that the output end of the medicine pump 4 is provided with a one-way valve to prevent backflow of the liquid medicine. The one-way valve is made of stainless steel, with a built-in spring and sealing gasket, and the opening pressure can be adjusted in the range of 0.1-0.3 MPa. When the medicine pump 4 is working, the liquid medicine pressure pushes the valve core open against the spring force, and the liquid medicine flows smoothly; when the medicine pump 4 stops working, the spring force makes the valve core reset quickly, and the sealing gasket completely blocks the flow passage to prevent backflow of the liquid medicine to the medicine tank 3.

[0059] When the drug pump 4 stops working, the one-way valve can effectively prevent the backflow of the drug liquid to the drug tank 3, avoid the cavity of the pipeline to cause the unstable spraying when the next start, and also prevent the damage of the pump body caused by the backflow of the drug liquid, thereby prolonging the service life of the equipment.

[0060] Embodiment 3:

[0061] The embodiment is basically the same as embodiment 1, and the difference lies in that the front spray rod 8 and the rear spray rod 9 are both provided with the anti-dripping valve 23 to prevent the dripping of the drug liquid when stopping. The anti-dripping valve is an electromagnetic control type and works in linkage with the drug pump 4. When the drug pump starts, the control center 18 sends a signal to the anti-dripping valve at the same time, and the valve is opened; when the drug pump stops working, the valve is quickly closed within 0.1 seconds, and the flow of the drug liquid is completely cut off. The anti-dripping valve 23 adopts Teflon sealing material and ceramic valve core, has the characteristics of corrosion resistance, wear resistance and fast response. The internal flow channel of the valve is optimized in design, and the pressure loss is small, which does not affect the flow and pressure in the normal spraying. Each valve is provided with a state indicating lamp, which can directly display the opening and closing state of the valve.

[0062] When working, the anti-dripping valve 23 is automatically closed during the spraying interval or stopping, and the flow of the drug liquid is cut off, which effectively avoids the dripping of the drug liquid from the spray head in the non-working state, saves the pesticide, and prevents the soil pollution and the crop pesticide damage.

[0063] Embodiment 4:

[0064] The embodiment is basically the same as embodiment 1, and the difference lies in that the front vertical rod 503 and the rear vertical rod 702 are both detachably connected with the plugging cover 16 at the bottom end, so as to facilitate the cleaning and maintenance of the pipeline. The plugging cover 16 is designed in a quick connector type. The quick connector is made of stainless steel and adopts a buckle type structure, and only needs to be rotated by 90 degrees to complete the installation or disassembly, which is simple and fast in operation. The plugging cover 16 is internally provided with a rubber sealing ring, so as to ensure the sealing property of the connection.

[0065] When working, the plugging cover 16 can be opened to flush and drain the inside of the integrated pipe after a long time of use, so as to prevent the deposition from blocking the spray head 10, keep the pipeline unobstructed, prolong the service life of the spraying system, and also facilitate the daily maintenance and cleaning.

[0066] In the present application, unless otherwise clearly specified and limited, the terms such as "mounting", "connection", "linkage", "fixing" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or can be integrated; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0067] In the present application, unless specifically stated and limited otherwise, a first feature "on" or "under" a second feature can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. Also, a first feature "over", "above" and "on top of" a second feature can be directly above or obliquely above the second feature, or simply mean that the first feature is horizontally higher than the second feature. A first feature "under", "below" and "underneath" a second feature can be directly below or obliquely below the second feature, or simply mean that the first feature is horizontally lower than the second feature.

[0068] Certain exemplary embodiments of the present application have been described above by way of illustration, and it will be apparent that, to those skilled in the art, changes in form and detail can be made without departing from the spirit and scope of the application. Therefore, the above-described drawings and descriptions are to be considered in all respects only as illustrative and not restrictive, and the scope of the application is indicated by the appended claims rather than by the foregoing description.
