Description

Technical Field

[0001] The present invention relates to the technical field of agricultural plant protection, and in particular to a device and method for preventing drift of plant protection sprays used in strip planting of soybeans and corns. Background Art

[0002] The current imbalance between soybean supply and demand is acute, threatening food security. To increase soybean production, a soybean-corn strip intercropping system has been adopted. This system expands soybean planting area and increases soybean yields without increasing arable land, resolving the conflict between corn and soybean production. Soybean-corn strip intercropping represents an innovative new agricultural development within my country's traditional intercropping system. This new system utilizes wide-narrow row arrangements, leveraging the advantages of high-lying crops in the side rows while increasing the sunlight exposure of lower-lying crops.

[0003] In order to ensure the harmonious coexistence of soybeans and corn in the same plot of land and double harvest in one season, full mechanization technology is the most suitable field management method under the new agricultural model. Especially when spraying herbicides in the field, since the applicable herbicides for soybeans and corn are quite different and cannot be mixed together, serious pesticide reactions are prone to occur. Therefore, whether field plant protection mechanization can meet the requirements of new agricultural technology is a difficult problem that needs to be solved urgently.

[0004] Since the new agronomic method of soybean and corn strip intercropping is a research proposal based on the new national conditions of agricultural land in my country, there is currently no demand for this method abroad. There is also little research and development in China on methods and mechanical devices for anti-drift partitioning in the context of specialized plant protection machinery under this new agronomic model. Since the soybean and corn strip planting model is adapted to local conditions, the number of rows and spacing between soybeans and corn are different. When simultaneously protecting two crops, in addition to avoiding pesticide damage caused by drift, it is also necessary to ensure that pesticide damage does not occur at the junction of soybeans and corn due to inconsistent crop heights. Currently, existing plant protection machinery and devices are difficult to meet all of these needs. If new plant protection machinery is specifically developed, it will greatly increase the cost of agricultural cultivation.

[0005] Therefore, there is an urgent need to realize a low-cost plant protection spray anti-drift isolation device that meets the needs of soybean and corn strip composite planting. Summary of the Invention

[0006] In order to solve the problems of the existing plant protection machinery's reaction to mixed pesticide damage in the soybean and corn strip composite planting scenario and the versatility of mechanized operation liquid drift technology, the purpose of the present invention is to provide a plant protection spray anti-drift isolation device and method for soybean and corn strip planting.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0011] According to the application, the number of the supporting bases, the lifting rod assemblies and the rib linkage structures is the same, and the three are arranged one by one in a one-to-one correspondence.

[0012] According to the application, a spray rod mounting hole is arranged on the supporting base and used for connecting the spray rod; a mounting flange or a mounting plate is welded on the supporting base and used for mounting and fixing the first servo motor; a boss is arranged on the supporting base, and a first rolling bearing is installed in the boss; and the first rolling bearing is used for nested connection with the lifting rod assembly.

[0013] According to the application, a first bevel gear is installed on the output shaft of the first servo motor.

[0014] Preferably, according to the present invention, the lifting rod assembly includes a spline shaft, a second bevel gear arranged at the lower end of the spline shaft and meshing with the first bevel gear, a fixed sleeve installed at the upper end of the spline shaft, and an annular mounting plate installed on the fixed sleeve; the lower end of the spline shaft is installed in the first rolling bearing; the upper end of the spline shaft is connected to the fixed sleeve through a second rolling bearing; and a plurality of first mounting holes distributed in an annular shape are provided on the annular mounting plate.

[0015] Preferably, according to the present invention, the mobile platform is provided with a plurality of second mounting holes distributed in a ring shape; the second mounting holes are used for connecting the umbrella rib connecting rod structure.

[0016] The movable platform includes a first flange block, a second flange block and a circular thin sheet; the circular thin sheet is fixed between the first flange block and the second flange block; the movable platform is sleeved on the outside of the spline shaft and is engaged with the spline shaft tooth profile through a keyway; the keyway is arranged on the movable platform, and when the first servo motor drives the spline shaft to rotate, the movable platform moves up and down along the keyway tooth profile of the spline shaft.

[0017] Preferably, according to the present invention, the umbrella rib connecting rod structure includes an active arm, a driven arm and a supporting arm.

[0018] The active arm and the driven arm are connected by a hinge to achieve rotation; one end of the active arm is connected to the first mounting hole of the annular mounting plate, and the other end is hinged to one end of the support arm; the other end of the support arm is connected to the second mounting hole opened on the mobile platform; one end of the driven arm is connected to the active arm, and the other end is connected to the fixed shaft sleeve; adjacent umbrella rib connecting rod structures are connected through the fixed shaft sleeve.

[0019] Preferably, according to the present invention, the anti-drifting extension and retraction unit has an annular fastening mounting plate at the rib connecting rod structure at the junction with the spray rod to nest and connect the driven arms of the rib connecting rod structures on both sides for fixed connection.

[0020] The present invention also includes a method for operating the aforementioned plant protection spray anti-drift isolation device for strip planting of soybeans and corns, the method comprising the following steps:

[0021] S1. Fix the support base to the spray boom, and then fix the annular fastening mounting plates on both sides of the device to both sides of the spray boom to fix the anti-drifting expansion and contraction device.

[0022] S2. Start the first servo motor, which drives the first bevel gear installed on its output shaft to rotate. The first bevel gear transmits torque to the second bevel gear on the lifting rod assembly. Since the spline shaft is connected to the inner ring of the rolling bearing, the spline shaft in the lifting rod assembly rotates under the drive of the second bevel gear, thereby providing an upward thrust to the mobile platform meshing with the spline shaft, causing the mobile platform to move up and down.

[0023] S3. When the mobile platform moves upward, the first servo motor rotates to provide torque, and the support arm in the umbrella rib connecting rod structure extends outward, driving the active arm to open, and the active arm drives the driven arm to extend outward until the mobile platform reaches the limit position; when the mobile platform moves downward, the first servo motor rotates in the opposite direction to provide torque, and the support arm in the umbrella rib connecting rod structure contracts inward, driving the active arm to contract, and the active arm drives the driven arm to contract inward until the support arm is completely contracted; the servo motor has an electromagnetic brake with a self-locking function. When certain conditions are met, the servo motor will self-lock and the gear will also be locked to achieve the movement limit of the mobile platform.

[0024] S4. Start the second servo motor through the pesticide partition unit installed on the base bearing to drive the pulley in the retraction coil box to rotate, so that the carbon wire on the pulley drives the baffle to move to adjust the height position of the baffle. When the second servo motor rotates forward, the baffle moves downward to achieve a stretching effect and the height becomes longer; when the second servo motor rotates reversely, the baffle moves upward to achieve a contraction effect and the height becomes shorter. Alternatively, when the second servo motor rotates reversely, the baffle moves downward to achieve a stretching effect and the height becomes longer; when the second servo motor rotates forward, the baffle moves upward to achieve a contraction effect and the height becomes shorter. Drive the carbon wire in the retraction coil box to tie it to the hole on the surface of the baffle to adjust the height of the baffle, so that it moves downward and increases the height of the drug barrier.

[0025] In step S2, the control method of each lifting rod assembly is the same. The first servo motor in the lifting rod assembly located in the middle of the spray rod is turned on first. After a certain period of time, the first servo motors in the remaining lifting rod assemblies are turned on at the same time.

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] (1) The present invention fixes the support base in an annular design and linear bearings on both sides in an axial direction perpendicular to the wind resistance, thereby ensuring its stability, thereby stabilizing the airflow resistance caused by the forward movement of the plant protection vehicle, and at the same time having the advantages of quick and convenient installation; and using a three-stage detachable structural layout to meet the problem of different spray boom lengths of plant protection machinery, realizing the innovation of the universal technology of the anti-drifting expansion and retraction unit for different rows and spacings of soybean and corn strip planting.

[0028] (2) The present invention realizes the forward and reverse rotation of the servo motor and controls the travel distance of the mobile platform through the linkage control of the servo motor and the lift platform (the lift platform refers to the lift rod assembly and the mobile platform) and uses PLC control to ensure that the device has highly automated control over the liquid spray prevention.

[0029] (3) The present invention proposes a special structural design of the mobile platform and the umbrella ribs. When the vehicle is moving forward, there will be wind resistance causing the liquid medicine sprayed from the nozzle to drift. The drifting liquid medicine will cause the problem of pesticide damage reaction. The umbrella rib connecting rod structure of this device is based on the principle of aerodynamics. The proposed asymmetric umbrella structure design is based on the principle of aerodynamics. The umbrella rib connecting rod structure located in the center is kept at 90 degrees with the spray rod and protrudes to resist the airflow. The active arms on both sides of the central umbrella rib connecting rod structure are kept at 45 degrees with the middle active arm and are retracted into an arc design, so that the airflow is diverted to both sides. Finally, the anti-drift expansion and retraction unit not only effectively reduces the wind resistance, but also prevents the liquid medicine sprayed from the nozzle from drifting.

[0030] (4) The present invention uses a retractable coil box in the pesticide partition unit to drive the pulley to move through the second drive motor, so that the carbon wire on the pulley pulls the baffle to move along the slot to adjust the height of the baffle, adapt to the height of crops at different times, and solve the problem of height difference between soybean and corn crops. The addition of a servo motor can ensure that the partition device can achieve any height limit, thereby isolating the two liquid medicines to prevent pesticide damage reactions.

The support base 11 has a mounting hole in a direction perpendicular to the spray rod, and a mounting flange is welded to connect the first servo motor 13. In order to improve versatility, the support base 11 adopts a ring design. The support base 11 is provided with a circular boss, and a rolling bearing 123 is installed in the boss. The rolling bearing 123 is nested and connected to the lifting rod assembly 12, and the lower end of the lifting rod assembly 12 is connected to the output shaft of the first servo motor 13. A mobile platform 14 is installed on the outside of the lifting rod assembly 12.

[0041] The umbrella rib linkage structure 15 includes an active arm 151, a passive arm 152, and a support arm 153.

One end of the support arm 153 is hinged to the active arm 151, and the other end is connected to the opening of the circular sheet 143 of the mobile platform 14. The umbrella rib linkage structure 15 is centered on the lifting rod assembly and is designed to be divided into three independently controlled sections to control the extension and retraction functions of the control device. The active arm is connected to the support arm, and the support arm is connected to the mobile platform. The angle between the three active arms is 45 degrees. The three active arms and passive arms in the umbrella rib structure located in the center form an arc surface.

[0042] According to a preferred embodiment of the present invention, the support base 11 is designed in a T-shape, with a mounting plate mounted on one side for mounting the first servo motor 13. The output shaft of the first servo motor 13 is connected to the first bevel gear 121. A fixed rolling bearing is mounted on the other side of the T-shape, and the lifting rod assembly 12 is nested inside. The support base 11 is bolted to an annular fixing mounting plate 16 and mounted on the spray boom. Preferably, the rolling bearing is a ball bearing.

[0043] Among them, the number of the lifting rod assemblies 12 is 3, which are fixedly matched with the support base 11 and symmetrically distributed on the spray rod. Each lifting rod assembly 12 includes a second bevel gear 122, a spline shaft 124, a fixed sleeve 125, and an annular mounting plate 126. The second bevel gear maintains a meshing relationship with the first bevel gear 121 at the output shaft end of the first servo motor 13, and is fixedly connected to the lower end of the spline shaft 124. A rolling bearing 123 is installed to maintain the connection between the spline shaft 124 and the support base 11. The upper end of the spline shaft 124 is also connected with a bearing and nested in the fixed sleeve 125. An annular mounting plate 126 is fixedly installed on the outer side of the fixed sleeve 125. The number of the annular mounting plates 126 is 3, and the angle and number of the openings are based on the umbrella rib connecting rod structure 15 and are connected to it.

[0044] The outer surface of the spline shaft 124 is nested with a movable platform 14, which includes a first flange block 141, a second flange block 142, and a circular thin sheet 143. The circular thin sheet 143 is fixed between the two flange blocks, and the opening is nested with the umbrella rib connecting rod structure 15. The opening design is the same as the annular mounting plate.

[0045] The anti-drift extension and retraction unit 1 has a mounting plate at the rib connecting rod structure 15 at the junction with the spray boom to install a flange linear bearing for fixed connection. The outer side of the mounting plate is punched with holes to install the second servo motor 27 and the retraction coil box 28 to ensure the vertical height adjustment of the baffle.

[0046] like Figure 4As shown, the pesticide dispensing barrier unit comprises a pair of dispensing barrier assemblies, one at each end of the spray boom. These assemblies include a slide rail module 21, a slot 22, a baffle 23, a curtain paper 24, a mounting plate 25, a base bearing 26, a second servo motor 27, and a retraction coil box 28. The slot is made of PVC, the baffle 23 is lightweight, the curtain paper 24 is plastic, and the mounting plate 25 is aluminum alloy.

[0047] Preferably, according to the present invention, the slide rail module 21 includes a rail fixedly connected to the slot 22 and a slider slidably engaged with the rail, and the slider is fixedly connected to the baffle 23 with a nut to achieve vertical height adjustment of the baffle.

[0048] According to a preferred embodiment of the present invention, the curtain paper 24 is fixed to the surface of the baffle 23 to prevent the drift of the liquid medicine.

[0049] According to a preferred embodiment of the present invention, both sides of the mounting plate 25 are fixedly connected to the slot 22, and the base bearing is fixedly connected to the upper surface of the mounting plate with bolts. The second servo motor 27 and the retraction coil box 28 are fixedly connected to the side surface of the mounting plate 25 via a support plate. The ends of the spray bar are respectively connected to a base bearing. Both sides of the baffle 23 are respectively connected to a slide module 21, and the slide module 21 slides in conjunction with the slot 22. The mounting plate 25 is disposed on top of the baffle 23. The base bearing 26, the second servo motor 27, and the retraction coil box 28 are all mounted on the mounting plate 25. The ends of the spray bar are respectively connected to a base bearing 26. The second servo motor 27 rotates the pulley in the retraction coil box 28, and a carbon wire on the pulley connects to the baffle 23.

[0050] The working process of the above-mentioned plant protection spray anti-drift isolation device for soybean and corn strip planting is as follows:

[0051] S1. First, fix the support base to the spray boom with bolts, and then fix the annular fastening mounting plates on both sides of the device to both sides of the spray boom to fix the anti-drifting expansion and contraction unit.

[0052] S2. Start the first servo motor. The rotation of the first servo motor drives the first bevel gear on its output shaft to rotate. The first bevel gear transmits torque to the second bevel gear on the lifting rod assembly. Due to the presence of the rolling bearing, the second bevel gear drives the spline shaft in the lifting rod assembly to rotate, and the mobile platform threadedly connected to the spline shaft can move along the axial direction of the spline shaft. The first servo motor can provide an upward thrust for the mobile platform. Step S2 is used to provide driving force for the anti-drift expansion and retraction unit. The innovative point is that the bevel gear cooperates to drive the spline shaft to achieve the lifting function and is applied to the anti-drift partition device.

[0053] S3, when the mobile platform starts to execute the command of moving upward, the first servo motor needs to rotate in positive direction to provide torque, the support arm in the umbrella linkage structure stretches outward, drives the active arm to open, and the active arm drives the driven arm to stretch outward until the mobile platform reaches the limit position. Conversely, when the mobile platform starts to execute the moving command downward, the servo motor needs to rotate in reverse direction to provide torque, the support arm in the umbrella linkage structure shrinks inward, drives the active arm to shrink, and the active arm drives the driven arm to shrink inward until the support arm completely shrinks. The above-mentioned movement process of the mobile platform is also applicable to the second lifting rod assembly and the third lifting rod assembly, and when the servo motor starts, the servo motor of the first lifting rod assembly is opened first for three seconds, and then the servo motors of the second lifting rod assembly and the third lifting rod assembly are opened simultaneously to achieve the unfolding effect of the device. The mobile platform, the lifting rod assembly and the umbrella linkage structure are cooperated with each other under the action of the servo motor to provide power, so that the device achieves the unfolding and folding effect. The asymmetric design of the umbrella linkage structure applied to the anti-drifting partition device is an innovation point.

[0054] S4, the medicine application partition unit installed through the base bearing is started, the servo motor drives the contraction coil box to adjust the height position of the baffle 23. In the embodiment, when the motor rotates in positive direction, the baffle moves downward to achieve the stretching effect and the height becomes longer, and when the motor rotates in reverse direction, the baffle moves upward to achieve the shrinking effect and the height becomes shorter. Alternatively, when the second servo motor rotates in reverse direction, the baffle moves downward to achieve the stretching effect and the height becomes longer, and when the second servo motor rotates in positive direction, the baffle moves upward to achieve the shrinking effect and the height becomes shorter. Adjusting the height of the medicine application partition unit can prevent the soybean and corn interplanting from causing different crop injury reactions during the growth of different time sequences. The medicine application partition unit in the embodiment has universality.

[0055] The above-mentioned embodiments only describe the preferred embodiments of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
