Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a multi-level spraying device for composite planting of soybeans and corns. Background Art

[0002] Soybean-corn composite planting is a highly efficient planting method, commonly known as soybean-corn strip composite planting. Its core lies in expanding spacing and increasing light, and shrinking plants to keep secrets. It solves the problem of corn and soybeans competing for land, while improving land utilization and farmers' planting income. The main arrangement methods of soybean-corn strip composite planting include 4:2 mode (4-row soybean belt and 2-row corn belt composite planting), 4:3 mode (4-row soybean belt and 3-row corn belt composite planting), 4:4 mode (4-row soybean belt and 4-row corn belt composite planting) and 6:3 mode (6-row soybean belt and 3-row corn belt composite planting).

[0003] However, there are some problems with the strip-based composite planting of soybeans and corn. For example, during the process of pest control of plants, due to the differences in stem heights, pest types, and drug dosages of soybeans and corn, there will be mutual influence when spraying. Specifically, since corn is taller and soybeans are shorter, the height and angle of the spray equipment need to be adjusted during spraying to ensure that the drug solution can evenly cover the leaves of the two crops. At the same time, the mutual influence of the two drugs needs to be avoided, which increases the difficulty and complexity of spraying.

[0004] The prior art proposes a Chinese patent for a corn and soybean composite boom sprayer (publication number CN218451326U) to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: "The corn seedlings and soybean seedlings are separated by a barrier component, and then the liquid medicine in the medicine storage component is transported to the spraying component by a medicine pump component, and then sprayed outward by the spraying component. Under the action of the barrier component, the phenomenon of two pesticides interfering with crops can be avoided, and cotton and linen are used as barrier components in the barrier component. When used in open areas, it can reduce wind resistance and is very convenient to use." However, this solution and the existing sprayer have the following problems:

[0005] The spray boom is set horizontally perpendicular to the direction of travel, and the nozzle is installed below the spray boom. The spray is achieved from top to bottom. However, the leaves of corn plants are large, and the ends of the leaves are usually drooping. Figure 5In the figure, a is a soybean plant, b is a corn plant, and c is the distance between adjacent soybeans and corns. After the pesticide is sprayed from top to bottom, most of it will be blocked and received by the upper leaves, and it is difficult to pass through the layers of leaves to the leaves below. After the leaves above receive more pesticides, the pesticide droplets gather on the leaves and form larger water droplets. The accumulation of pesticides on the leaves will further increase the drooping state of the leaves and cause some droplets to flow downward. The flowing droplets are located on the periphery of the plant and flow in the direction away from the plant, so they cannot be received by the lower leaves. Summary of the invention

[0006] The purpose of the present invention is to provide a multi-level spraying device for composite planting of soybeans and corns, so as to solve the problem that after the pesticide is sprayed from top to bottom, it is difficult to pass through the layers of leaves to be transferred to the leaves below and cannot be received by the leaves below.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A multi-level spraying device for composite planting of soybean and corn comprises a spraying vehicle body, on which a first spraying component for spraying corn plants and a second spraying component for spraying soybean plants are arranged; the first spraying component comprises a flip frame rotatably connected to the front end of the spraying vehicle body, a motor is fixedly installed on the top of the spraying vehicle body, an output end of the motor and a central axis of the flip frame are connected via a belt and a pulley transmission, two mounting rods are symmetrically arranged at one end of the flip frame away from the spraying vehicle body, two spray rods are fixedly connected to the outer side walls of the mounting rods, a plurality of first nozzles are fixedly connected to the outer side walls of the spray rods along the axial direction, and the plurality of first nozzles are respectively used for spraying leaves at different heights of corn plants medicine; a transmission component is arranged on the inner side of the flip frame, and the transmission component is used to keep the spray rod in a vertical state during the flipping process of the flip frame; the second spraying component includes a second nozzle fixedly installed at the front end of the sprayer body, and a medicine storage tank is fixedly connected to the sprayer body, and two independent chambers are arranged inside the medicine storage tank for storing different pesticides respectively, and two pump bodies are installed on the sprayer body, and the two ends of one pump body are respectively connected to the first nozzle and a chamber of the medicine storage tank, and the two ends of the other pump body are respectively connected to the second nozzle and the other chamber of the medicine storage tank; partition components are arranged on both sides of the sprayer body for separating the spraying areas of the first spray component and the second spray component, and the partition components are arranged to be a retractable structure.

[0009] In this embodiment, when spraying is not in progress, in order to avoid the bottom of the spray rod from colliding with the ground, the motor is controlled to drive the flip frame to rotate until it is in a vertical state, and the spray rod is also in a vertical state, so that the first spraying component is folded as a whole on the main body of the sprayer, thereby reducing the volume of the device as a whole when not spraying; the motor is controlled to drive the flip frame to rotate, so that the flip frame is tilted, thereby pushing the spraying area of ​​the first spraying component forward and keeping a relatively long distance from the cab, and the spray rod is always vertically downward under the action of the transmission component, and a plurality of first nozzles are installed on the axial direction of the spray rod, which can realize multi-level spraying of corn plants at different heights during operation, thereby avoiding the situation where the agent can only gather at the upper end of the plant, and improving the spraying effect of the agent.

[0010] A further improvement of the technical solution of the present invention is that: a hollow shaft is rotatably connected between the inner sides of the flip frame, and both ends of the hollow shaft extend to the outside of the flip frame, and two strip grooves are symmetrically provided on the side wall of the hollow shaft, and an adjusting seat is fixedly connected to one side of the flip frame, and a bidirectional screw is rotatably connected between the two sides of the inner wall of the adjusting seat, one end of the bidirectional screw extends to the outside of the adjusting seat and is fixedly connected with a turning handle, and the outside of the bidirectional screw is symmetrically threaded with two sliding blocks, and the sliding blocks are slidably connected to the inner wall of the adjusting seat, and the outside of the hollow shaft is symmetrically slidably connected to two sliding sleeves, and the outside of the sliding sleeves are rotatably connected to adapter tubes, and the adapter tubes correspond to the sliding blocks one by one and are fixedly connected, and two key shafts are symmetrically slidably connected between the inner walls of the hollow shaft, and the key shafts match the internal shapes of the hollow shafts and are both prismatic, and the key shafts correspond to the sliding sleeves one by one and are fixedly connected; and two mounting rods are respectively fixedly connected to the ends away from the two key shafts.

[0011] By adopting the above technical scheme, the position of the first spraying component is adjusted according to the distance between two adjacent corn belts. Specifically, the target state that needs to be adjusted is determined according to the distance between the nearest corn plants on both sides of the soybean belt. By turning the handle, the bidirectional screw is driven to rotate, so that the two sliders slide in opposite directions and at equal distances, and drive the adapter tube, sliding sleeve, key shaft, mounting rod and spray rod to move until the corn plants are in the middle of the first nozzle on each side.

[0012] A further improvement of the technical solution of the present invention is that the transmission component includes two transmission gears symmetrically connected to the two sides of the flip frame, and the two sides of the spray vehicle body are symmetrically fixedly connected with mounting plates, one side of the mounting plate is fixedly connected with an inner gear ring, the inner gear ring is meshingly connected with the transmission gear, the central axis of the transmission gear extends to the inner side of the flip frame and is fixedly connected with a first pulley, the outer side of the hollow shaft is fixedly connected with a second pulley, and the second pulley is connected to the first pulley through a belt drive.

[0013] By adopting the above technical scheme, the motor is controlled to drive the turning frame to rotate, so that the turning frame is tilted, thereby pushing the spraying area of ​​the first spraying component forward and keeping a relatively long distance from the cab; after turning, ensure that the mounting rod is higher than the top position of the corn plant and the bottom of the spray rod is at least cm above the ground; during the turning process, the transmission gear revolves around the center position of the inner gear ring, so that the transmission gear rotates at the same time and drives the first pulley to rotate, and further, the second pulley is driven to rotate by the transmission belt, so that the hollow shaft, key shaft, mounting rod and spray rod all rotate around the axis of the hollow shaft, so that the spray rod and the turning frame rotate in opposite directions and the rotation angles are equal, so that the spray rod is always vertically downward to complete the deployment.

[0014] A further improvement of the technical solution of the present invention is that: the partition component includes a connecting frame fixedly connected to the side wall of the mounting rod, the connecting frame is fixedly connected to a crossbeam at one end away from the mounting rod, four storage boxes are symmetrically fixedly connected to the bottom of the crossbeam, a through slot is opened on one side of the storage box, the top and bottom of the storage box are fixedly connected to a control box, a winding roller is rotatably connected between the top and bottom of the inner wall of the storage box, a dividing film is wound on the outer side of the winding roller, one end of the dividing film is fixedly connected to the winding roller, and the other end extends to the outside of the storage box and is fixedly connected to a pull plate, and a hanging buckle is fixedly connected to the middle position of the pull plate; both ends of the central axis of the winding roller extend to the inside of the corresponding control box, and a spring is connected between the central axis of the winding roller and the inner wall of the control box; a suspension structure is provided at the tail of the sprayer body, and the suspension structure is used to provide hanging buckle for suspension.

[0015] By adopting the above technical solution, the hanging buckle is pulled to make the pull plate move accordingly, and each separation membrane is pulled out until the hanging buckle is hung on the hanging ring. During the process, the spring accumulates potential energy. After the four separation membranes are pulled out and hung, multiple separation areas are formed. The separation area extends from the front of the sprayer body to the rear of the expansion frame, and the spray area of ​​the first spraying component is at the front end of the separation area. As the sprayer body moves, the spraying area can be in a fenced environment for a long time. On the one hand, the drift of the drug (natural drift and wind drift) is prevented. On the other hand, it can effectively prevent some pests from having a stress response and migrating to the soybean plants after spraying the drug.

[0016] A further improvement of the technical solution of the present invention is that the suspension structure includes an expansion frame rotatably connected to the rear part of the sprayer body, the bottom of the expansion frame is symmetrically fixedly connected with four slide rails, a number of positioning holes are equidistantly provided on the slide rails, an adjusting block is slidably connected to the outer side of the slide rails, slide grooves are symmetrically provided on both sides of the inner wall of the adjusting block, a slide rod is fixedly connected between the inner walls of the slide grooves, a pad is slidably connected between the outer sides of the slide rods, a limiting groove is provided on the slide rails, the pad is slidably connected to the limiting groove, a spring is sleeved on the outer side of the slide rod, and a positioning pin used in conjunction with the positioning hole is fixedly connected to one side of the inner wall of the adjusting block; a fixed block is fixedly connected to the rear part of the sprayer body, a lock buckle is fixedly connected to the top and one of the side walls of the fixed block, and a latch used in conjunction with the lock buckle is fixedly connected to one side of the expansion frame; an auxiliary bracket is fixedly connected to the rear part of the sprayer body; a hanging ring is fixedly connected to one side of the adjusting block.

[0017] By adopting the above technical solution, the height of the adjustment block is adjusted according to the height of the storage box after adjustment. Specifically, the hook is pulled out to the slide rail position, and then the side of the adjustment block close to the hanging ring is pressed, so that the spring is compressed and drives the positioning pin to leave the corresponding positioning hole, so that the adjustment block can be slid along the slide rail until it slides to the position closest to the hook, and then the adjustment block is released (no longer pressed) and the positioning pin is fine-tuned until the positioning pin is aligned with the nearest positioning hole. At this time, the adjustment block is pushed back to its original position under the rebound of the spring, and the positioning pin is inserted into the corresponding positioning hole.

[0018] A further improvement of the technical solution of the present invention is that two sponges are connected to one side of the storage box close to the through groove by screws, the sponge includes a sponge part and a base part, the sponge part contacts both sides of the partition membrane, a slope is provided on the side of the pull plate close to the partition membrane, and the distance between the two base parts is greater than the width of the pull plate; a guide groove is provided on the top of the control box located below the storage box.

[0019] By adopting the above technical solution, a sponge is arranged on one side of the storage box to wipe the separator membrane and absorb the medicine, thereby reducing the amount of medicine remaining after the separator membrane is rolled up, and can effectively remove medicines with larger particles; when the separator membrane is rolled up to the position where the pull plate is inserted between the two sponges, the pull plate will gradually squeeze the sponge part, so that the medicine in the sponge part is squeezed out, and no special handling is required by the operator, thereby reducing the actual operation amount and reducing the safety hazards of the medicine to the operator.

[0020] A further improvement of the technical solution of the present invention is that a plurality of levers are fixedly connected to the side wall of the spray rod at equal intervals, the levers are arc-shaped, with the concave side facing upward, and the ends of the levers are provided with rounded corners.

[0021] By adopting the above technical solution, an arc-shaped lever is provided. When the main body of the spraying vehicle is moving, the lever pushes the blade upward and upward, so that the blade covers more horizontal area (increases the area in the top view), thereby improving the receiving effect of the agent.

[0022] A further improvement of the technical solution of the present invention is that a shield is fixedly connected to the front end of the spraying vehicle body, and the shield is used to shield the spraying area of ​​the second spraying component.

[0023] The above technical solution is adopted to facilitate fencing off the spraying area (soybean plant belt) of the first spraying component, thereby reducing the impact of the spray of the pesticide used for soybeans on corn, and at the same time reducing the impact of the pesticide used for corn on soybeans.

[0024] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0025] 1. The present invention controls the motor to drive the turning frame to rotate, thereby tilting the turning frame, so as to push the spraying area of ​​the first spraying component forward and keep a relatively long distance from the cab. The spray rod is always vertically downward under the action of the transmission component, and a plurality of first nozzles are installed on the axial direction of the spray rod. When working, multi-level spraying can be achieved on corn plants at different heights, thereby avoiding the situation that the medicine can only gather at the upper end of the plant, and improving the spraying effect of the medicine.

[0026] 2. The present invention sets the first spraying components located on both sides as a distance-adjustable structure. In actual use, the first spraying components can be adjusted according to the distance between corn plants on both sides of the soybean belt. Specifically, the target state to be adjusted is determined according to the distance between the nearest corn plants on both sides of the soybean belt. By turning the handle, the bidirectional screw is driven to rotate, so that the two sliders slide in opposite directions and at equal distances, and drive the adapter tube, sleeve, key shaft, mounting rod and spray rod to move until the corn plants are in the middle of the first nozzle on each side.

[0027] 3. The present invention pulls the hanging buckle to move the pull plate and pull out each partition membrane until the hanging buckle is hung on the hanging ring. During the process, the spring accumulates potential energy. After the four partition membranes are pulled out and hung, a plurality of partition areas are formed. The partition area extends from the front of the sprayer body to the rear of the expansion frame, and the spray area of ​​the first spraying component is at the front end of the partition area. As the sprayer body moves, the spraying area can be in the enclosure environment for a long time. On the one hand, the drift of the drug (natural drift and wind drift) is prevented. On the other hand, it can effectively prevent some pests from migrating to the soybean plants due to stress response after spraying the drug.

[0028] 4. The present invention provides a sponge on one side of the storage box for wiping the partition membrane and adsorbing the medicine, thereby reducing the amount of medicine remaining after the partition membrane is rolled up, and can effectively remove medicines with larger particles; the sponge part will also carry the medicine after wiping and adsorbing the medicine on the partition membrane, so the pull plate is also improved in this scheme, and an inclined surface is provided on the pull plate. When the partition membrane is rolled up to the position where the pull plate is inserted between the two sponges, the pull plate will gradually squeeze the sponge part, so that the medicine in the sponge part is squeezed out and flows downward, and part of the medicine flows to the guide groove and is discharged, thereby reducing the residual amount of medicine in the sponge, and does not require the operator to perform special processing, reducing the actual amount of operation, and at the same time reducing the safety hazards of the medicine to the operator.

[0029] 5. The present invention provides an arc-shaped lever. When the main body of the sprayer is moving, the lever pushes the blades upward and upward, so that the blades cover more horizontal areas. Combined with the multi-level first nozzles, the atomized medicine can be fully received, thereby improving the receiving effect of the medicine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The present invention is further described in detail below in conjunction with embodiments:

[0048] Example 1

[0049] like Figure 1 , Figure 2 and Figure 8As shown, the present invention provides a multi-level spraying device for composite planting of soybeans and corns, including a spraying vehicle body 1, on which a first spraying component for spraying corn plants and a second spraying component for spraying soybean plants are arranged; the first spraying component includes a turning frame 2 rotatably connected to the front end of the spraying vehicle body 1, a motor 47 is fixedly installed on the top of the spraying vehicle body 1, and the output end of the motor 47 is connected to the central axis of the turning frame 2 through a belt and a pulley transmission. Two mounting rods 4 are symmetrically arranged at one end of the turning frame 2 away from the spraying vehicle body 1, and two spray rods 5 are fixedly connected to the outer side walls of the mounting rods 4, and a plurality of first nozzles 13 are fixedly connected to the outer side walls of the spray rods 5 along the axial direction, and the plurality of first nozzles 13 are respectively used for spraying corn plants at different heights. The blades spray the pesticide; a transmission component is provided on the inner side of the turning frame 2, and the transmission component is used to keep the spray rod 5 in a vertical state during the turning process of the turning frame 2; the second spraying component includes a second nozzle 42 fixedly installed on the front end of the spraying vehicle body 1, and a medicine storage tank 14 is fixedly connected to the spraying vehicle body 1. Two independent chambers are arranged inside the medicine storage tank 14 for storing different pesticides respectively. Two pump bodies are installed on the spraying vehicle body 1, and the two ends of one pump body are respectively connected to the first nozzle 13 and a chamber of the medicine storage tank 14, and the two ends of the other pump body are respectively connected to the second nozzle 42 and another chamber of the medicine storage tank 14; partition components are provided on both sides of the spraying vehicle body 1 for separating the spraying areas of the first spraying component and the second spraying component, and the partition components are arranged to be a retractable structure.

[0050] In this embodiment, when spraying is not performed, in order to prevent the bottom of the spray rod 5 from colliding with the ground, the motor 47 is controlled to work, driving the flip frame 2 to rotate until it is in a vertical state, and the spray rod 5 is also in a vertical state, so that the first spraying component is folded on the spray vehicle body 1 as a whole, thereby reducing the volume of the entire device when not spraying;

[0051] When spraying medicine, the motor 47 is controlled to drive the turning frame 2 to rotate, so that the turning frame 2 is tilted, thereby pushing the spraying area of ​​the first spraying component forward and keeping a relatively long distance from the cab, and the spray rod 5 is always vertically downward under the action of the transmission component, and a plurality of first nozzles 13 are installed on the axial direction of the spray rod 5. When working, multi-level spraying can be achieved on corn plants at different heights, thereby avoiding the situation where the medicine can only gather at the upper end of the plant, and improving the spraying effect of the medicine.

[0052] Due to the lighting conditions of corn plants, the upper leaves usually receive more sunlight, so the plants grow more luxuriantly in the upper part, attracting more pests, and the upper leaves are more susceptible to weather and temperature changes. For example, when the temperature is higher, insects may be more likely to breed, while the lower leaves are closer to the ground and may be affected by factors such as soil moisture and pathogens, resulting in them being relatively less affected by certain pests. Specifically, corn borers tend to enter from the upper part of the plant in search of tenderer and more nutritious leaves. Therefore, preferably, when the corn plants are taller and the specific length is greater than the length of the spray rod 5, the adjustment process ensures that the spray rod 5 is above the corn plants to meet the needs of spraying the upper leaves.

[0053] The wheel width of the spraying vehicle body 1 is smaller than the gap c between the soybean belt and the corn belt.

[0054] like Figure 6 , Figure 7 and Fig.13 As shown, preferably, a hollow shaft 3 is rotatably connected between the inner sides of the flip frame 2, and both ends of the hollow shaft 3 extend to the outside of the flip frame 2. Two strip grooves 11 are symmetrically provided on the side walls of the hollow shaft 3. An adjusting seat 6 is fixedly connected to one side of the flip frame 2. A bidirectional screw 7 is rotatably connected between the two sides of the inner wall of the adjusting seat 6. One end of the bidirectional screw 7 extends to the outside of the adjusting seat 6 and is fixedly connected with a turning handle. Two sliders 8 are symmetrically threadedly connected to the outer side of the bidirectional screw 7. The slider 8 is slidably connected to the inner wall of the adjusting seat 6. Two sliding sleeves 10 are symmetrically slidably connected to the outer side of the hollow shaft 3. A transfer tube 9 is rotatably connected to the outer side of the sliding sleeve 10. The transfer tube 9 corresponds to the slider 8 one by one and is fixedly connected. Two key shafts 12 are symmetrically slidably connected between the inner walls of the hollow shaft 3. The key shaft 12 matches the internal shape of the hollow shaft 3 and is both prismatic. The key shaft 12 corresponds to the sliding sleeve 10 one by one and is fixedly connected. The two mounting rods 4 are respectively fixedly connected to the ends of the two key shafts 12 that are away from each other.

[0055] In this embodiment, the position of the first spraying component is adjusted according to the distance between two adjacent corn belts. Specifically, the target state that needs to be adjusted is determined according to the distance between the nearest corn plants on both sides of the soybean belt. By turning the handle, the bidirectional screw 7 is driven to rotate, so that the two sliders 8 slide. The sliders 8 slide in opposite directions and at equal distances, and drive the adapter tube 9, the sliding sleeve 10, the key shaft 12, the mounting rod 4 and the spray rod 5 to move until the corn plants are in the middle of the first nozzle 13 on each side.

[0056] like Figure 3 and Figure 7As shown, preferably, the transmission component includes two transmission gears 20 symmetrically connected to the two sides of the flip frame 2, and the two sides of the spray vehicle body 1 are symmetrically fixedly connected with the mounting plates 18, one side of the mounting plate 18 is fixedly connected with the inner gear ring 19, and the inner gear ring 19 is meshingly connected with the transmission gear 20. The central axis of the transmission gear 20 extends to the inner side of the flip frame 2 and is fixedly connected with the first pulley 21, and the outer side of the hollow shaft 3 is fixedly connected with the second pulley 22, and the second pulley 22 is connected to the first pulley 21 through a belt drive.

[0057] In this embodiment, the motor 47 is controlled to rotate to drive the flip frame 2, so that the flip frame 2 is tilted, thereby pushing the spraying area of ​​the first spraying component forward and maintaining a relatively long distance from the cab; after flipping, it is ensured that the mounting rod 4 is higher than the top position of the corn plant and the bottom of the spray rod 5 is at least 5 cm above the ground. During the flipping process, the transmission gear 20 revolves around the center position of the inner gear ring 19, so that the transmission gear 20 rotates at the same time and drives the first pulley 21 to rotate. Further, the second pulley 22 is driven to rotate through the transmission belt, so that the hollow shaft 3, the key shaft 12, the mounting rod 4 and the spray rod 5 all rotate around the axis of the hollow shaft 3, so that the spray rod 5 and the flip frame 2 rotate in opposite directions and the rotation angles are equal, so that the spray rod 5 is always vertically downward to complete the deployment.

[0058] Example 2

[0059] like Figure 3 , Figure 4 and Fig. 9 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the partition component includes a connecting frame 41 fixedly connected to the side wall of the mounting rod 4, the end of the connecting frame 41 away from the mounting rod 4 is fixedly connected to the crossbeam 15, the bottom of the crossbeam 15 is symmetrically fixedly connected to four storage boxes 16, one side of the storage box 16 is provided with a through slot, the top and bottom of the storage box 16 are fixedly connected to the control box 17, the top and bottom of the inner wall of the storage box 16 are rotatably connected to the winding roller 26, and the winding roller 26 is rotatably connected to the top and bottom of the inner wall of the storage box 16. A separation film 27 is wound on the outside of the roller 26, one end of the separation film 27 is fixedly connected to the winding roller 26, and the other end extends to the outside of the storage box 16 and is fixedly connected to a pull plate 28, and a hook 29 is fixedly connected to the middle position of the pull plate 28; both ends of the central axis of the winding roller 26 extend to the inside of the corresponding control box 17, and a spring 33 is connected between the central axis of the winding roller 26 and the inner wall of the control box 17; a suspension structure is provided at the rear of the spray vehicle body 1, and the suspension structure is used to provide suspension to the hook 29.

[0060] In this embodiment, the hook 29 is pulled to move the pull plate 28, and each partition membrane 27 is pulled out until the hook 29 is hung on the hanging ring 34. During the process, the spring 33 accumulates potential energy. After the four partition membranes 27 are pulled out and hung, multiple partition areas are formed. The partition area extends from the front of the sprayer body 1 to the rear of the expansion frame 23, and the spray area of ​​the first spraying component is at the front end of the partition area. As the sprayer body 1 moves, the spraying area can be in the enclosure environment for a long time. On the one hand, the drift of the drug (natural drift and wind drift) is prevented, and on the other hand, it can effectively prevent some pests from migrating to the soybean plants due to stress response after spraying the drug;

[0061] When not in use, the separation membrane 27 can be rolled up into the storage box 16 by the clockwork 33 structure, thereby preventing people from touching or damaging the separation membrane 27 .

[0063] like Figure 5 , Fig.10 and Fig.14 As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, the suspension structure includes an expansion frame 23 rotatably connected to the rear of the spraying vehicle body 1, and the bottom of the expansion frame 23 is symmetrically fixedly connected with four slide rails 24, and the slide rails 24 are equidistantly provided with a plurality of positioning holes 39, and the outer side of the slide rail 24 is slidably connected with an adjustment block 25, and the inner walls of the adjustment block 25 are symmetrically provided with slide grooves 35, and the inner walls of the slide grooves 35 are fixedly connected with slide rods 36, and the outer sides of the slide rods 36 are slidably connected with pads 37, and the slide rails 24 are provided with a plurality of positioning holes 39, and the outer sides of ... The limiting groove 50, the cushion block 37 is slidably connected to the limiting groove 50, the outer side of the slide rod 36 is sleeved with a spring 38, and one side of the inner wall of the adjustment block 25 is fixedly connected with a positioning pin 40 used in conjunction with the positioning hole 39; the tail of the spray vehicle body 1 is fixedly connected with a fixing block 45, and the top and one of the side walls of the fixing block 45 are fixedly connected with a lock buckle 46, and one side of the expansion frame 23 is fixedly connected with a latch 44 used in conjunction with the lock buckle 46; the tail of the spray vehicle body 1 is fixedly connected with an auxiliary bracket 48; one side of the adjustment block 25 is fixedly connected with a hanging ring 34.

[0064] Since the spray rod 5 needs to be adjusted to a higher position for taller corn plants, the storage box 16 is adjusted to a higher position accordingly. In order to keep the partition membrane 27 in a horizontal state after being pulled out, in the present embodiment, the height of the adjustment block 25 is adjusted according to the height of the adjusted storage box 16. Specifically, the hook 29 is pulled out to the position of the slide rail 24, and then the side of the adjustment block 25 close to the hanging ring 34 is pressed, so that the spring 38 is compressed and drives the locating pin 40 to leave the corresponding locating hole 39, so that the adjustment block 25 can slide along the slide rail 24 until it slides to the position closest to the hook 29, and then the adjustment block 25 is released (no longer pressed) and the adjustment block 25 is fine-tuned at the same time until the locating pin 40 is aligned with the nearest locating hole 39. At this time, the adjustment block 25 is pushed back to its original position under the rebound of the spring 38, and the locating pin 40 is inserted into the corresponding locating hole 39.

[0065] Example 4

[0066] like Fig. 9 and Fig.12 As shown, on the basis of Example 3, the present invention provides a technical solution: preferably, two sponges are connected to the side of the storage box 16 close to the through groove by screws, and the sponge includes a sponge part 31 and a base part 30, the sponge part 31 contacts both sides of the partition membrane 27, and a slope is provided on the side of the pull plate 28 close to the partition membrane 27, and the distance between the two base parts 30 is greater than the width of the pull plate 28; a guide groove 32 is provided on the top of the control box 17 located below the storage box 16.

[0067] The separation film 27 will adhere to a large amount of medicine during the spraying process. If it is directly retracted after use, the medicine will remain in the storage box 16. The residual accumulation of medicine will cause certain safety problems for the operator, and the residual medicine will flow out during the subsequent movement of the spraying vehicle body 1, causing pollution to the environment and also posing a safety hazard.

[0068] In this embodiment, a sponge is provided on one side of the storage box 16 to wipe the separation film 27 and absorb the medicine, thereby reducing the amount of medicine remaining after the separation film 27 is rolled up, and can effectively remove medicine with larger particles;

[0069] Furthermore, after the sponge portion 31 wipes and absorbs the medicine on the separation membrane 27, it itself will also carry the medicine. Therefore, the pull plate 28 is also improved in the present scheme. A slope is set on the pull plate 28. When the separation membrane 27 is rolled up to the position where the pull plate 28 is inserted between the two sponges, the pull plate 28 will gradually squeeze the sponge portion 31, so that the medicine in the sponge portion 31 is squeezed out and flows downward. Part of the medicine flows to the guide groove 32 and is discharged, thereby reducing the residual amount of medicine in the sponge. The operator does not need to perform special processing, which reduces the actual operation amount and reduces the safety hazard of the drug to the operator.

[0070] Example 5

[0071] like Figure 7 and Figure 8 As shown, based on Example 4, the present invention provides a technical solution: Preferably, a plurality of levers 49 are equidistantly fixedly connected to the side wall of the spray rod 5, the levers 49 are arc-shaped, with the concave side facing upward, and the ends of the levers 49 are provided with rounded corners to avoid damaging the leaves of the corn plants.

[0072] Since the leaves of corn plants are large, some leaves have drooping ends. Figure 5 As shown, the outer periphery of the corn plant leaves tends to droop, which causes the pesticide sprayed by the first nozzle 13 to impact the front of the leaves, thereby causing the leaves to droop further and unable to fully receive the pesticide;

[0073] In this embodiment, by providing an arc-shaped lever 49, when the spray vehicle body 1 is moving, the lever 49 pulls the blades upward and upward, so that the blades cover more horizontal area (increase the area in the top view), thereby improving the receiving effect of the agent.

[0074] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, a shield 43 is fixedly connected to the front end of the spraying vehicle body 1, and the shield 43 is used to shield the spraying area of ​​the second spraying component.

[0075] In this embodiment, the spraying area (soybean plant belt) of the first spraying component is enclosed to reduce the impact of the pesticide spray for soybeans on corn, and at the same time reduce the impact of the pesticide spray for corn on soybeans.

[0076] The working principle of the multi-level spraying device for soybean-corn composite planting is described in detail below.

[0077] like Figure 1-Figure 15 As shown, the two chambers of the medicine storage tank 14 are respectively filled with insecticides for corn plants and insecticides for soybean plants. The two pump bodies have independent control systems. During the spraying process, the corn plant insecticide can be extracted through one of the pump bodies and sprayed out from the first nozzle 13 after being atomized, while the soybean plant insecticide can be extracted through the other pump body and sprayed out from the second nozzle 42 after being atomized.

[0078] Before spraying, the position of the first spraying component is adjusted according to the distance between two adjacent corn belts. Specifically, the target state that needs to be adjusted is determined according to the distance between the nearest corn plants on both sides of the soybean belt. By turning the handle, the bidirectional screw 7 is driven to rotate, so that the two sliders 8 slide (in opposite directions and at equal distances), and the adapter tube 9, the sliding sleeve 10, the key shaft 12, the mounting rod 4 and the spray rod 5 are driven to move until the corn plants are in the middle of the first nozzle 13 on each side (each side includes multiple groups of first nozzles 13 arranged longitudinally, and each group of first nozzles 13 includes two atomizing nozzles arranged opposite to each other); after the adjustment is completed, the motor 47 is controlled to work to drive the turning frame 2 to rotate, so that the turning frame 2 The rotating frame 2 is tilted, thereby pushing the spraying area of ​​the first spraying component forward and maintaining a relatively large distance from the cab; after flipping, it is ensured that the mounting rod 4 is higher than the top position of the corn plant and the bottom of the spray rod 5 is at least 5 cm above the ground. During the flipping process, the transmission gear 20 revolves around the center position of the inner gear ring 19, so that the transmission gear 20 rotates at the same time and drives the first pulley 21 to rotate. Further, the second pulley 22 is driven to rotate through the transmission belt, so that the hollow shaft 3, the key shaft 12, the mounting rod 4 and the spray rod 5 all rotate around the axis of the hollow shaft 3, so that the spray rod 5 and the flip frame 2 rotate in opposite directions and the rotation angle is equal, so that the spray rod 5 is always vertically downward to complete the deployment.

[0079] The expansion frame 23 can be expanded or folded by unlocking the latch 44. Specifically, the latch 44 includes a lock frame and a lock rod slidably connected to the lock frame, the lock rod has a limit rod, and the lock frame includes a gear slot. After the lock rod is pulled out from the lock buckle 46, the expansion frame 23 can be flipped until its bottom contacts the auxiliary bracket 48. At this time, the lock rod is opposite to the lock buckle 46 located at the top of the fixed block 45. By inserting the lock rod into the lock buckle 46 and rotating the lock rod so that the limit rod is stuck in the gear slot, the expansion frame 23 is expanded and fixed.

[0080] Pull the hook 29 to move the pull plate 28 and pull out each partition membrane 27 until the hook 29 is hung on the hanging ring 34. During the process, the spring 33 accumulates potential energy. After the four partition membranes 27 are pulled out and hung, a plurality of partition areas are formed. The partition area extends from the front of the sprayer body 1 to the rear of the expansion frame 23, and the spray area of ​​the first spraying component is at the front end of the partition area. As the sprayer body 1 moves forward, the spraying area can be in a fenced environment for a long time. On the one hand, the drift of the drug (natural drift and wind drift) is prevented. On the other hand, it can effectively prevent some pests from having a stress response and migrating to the soybean plants after spraying the drug.

[0081] Reference Fig.15It is a schematic diagram of the composite planting layout under the soybean-corn 4:2 mode. Based on the relatively short soybean plants, during the spraying process, the sprayer body 1 is controlled to travel on the gap c between the soybean belt and the corn belt, wherein the wheel travel trajectory is the area between the soybean belt a and the corn belt b, which has a large distance; and during the spraying process of the sprayer body 1, the pump body is controlled to adapt to complete the spraying, wherein the virtual frame shown in the figure is the area sprayed after the sprayer body 1 travels a single trip, and the arrows on both sides of the corn belt b indicate the direction in which the first spraying component sprays the corn belt b when the sprayer body 1 passes by.

[0082] After spraying is completed, by disengaging the hanging buckle 29 from the hanging ring 34 and holding the hanging buckle 29 close to the storage box 16, the winding roller 26 rotates under the action of the spring 33, and the partition film 27 is wound along with the winding roller 26 (the operator keeps holding it to avoid twisting and winding of the partition film, while ensuring slow release). During the winding process of the partition film 27, the partition film 27 slides relative to the sponge part 31, so that the sponge wipes the partition film 27, and the medicine remaining on the partition film 27 is adsorbed on the sponge until the pull plate 28 is inserted between the two sponge parts 31, and the pull plate 28 gradually transitions from the inclined part to the insertion of the entire pull plate 28. The sponge part 31 is squeezed during the process, so that the medicine in the sponge is squeezed out, and the medicine drips downward, and part of the medicine flows out from the guide groove 32, thereby reducing the medicine remaining on the partition film 27.

[0083] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
