Description

Technical Field

[0001] This invention belongs to the field of sowing and planting technology, and in particular relates to a corn-wheat intercropping shallow buried drip irrigation and closed weeding staggered no-till planter. Background Technology

[0002] As research continues to deepen, intercropping between corn and other grain crops such as soybeans and wheat has gradually attracted attention. The underlying principle is to reduce the light and temperature stress on corn through intercropping, so that corn and other crops such as soybeans and wheat can make full use of light and heat resources.

[0003] The fertigation technology dissolves the fertilizer needed during the vigorous growth period of corn into the irrigation water and delivers it to the corn roots through drip irrigation. It has the advantages of rapid fertilization, avoiding fertilizer loss, and improving corn yield and fertilizer utilization.

[0004] However, due to issues such as inconsistent planting times for various crops, uncoordinated plant protection methods, and inconvenient drip irrigation tape installation, this planting method, which utilizes light and temperature efficiently, faces the following problems during its application:

[0005] 1. Because wheat is sown earlier and corn is sown later, the sowing times for corn and wheat are not synchronized;

[0006] 2. When corn, soybeans, or wheat are intercropped in strips, the application of herbicides to corn can cause phytotoxicity to soybeans and wheat.

[0007] 3. Drip irrigation tape is laid by covering the soil with the soil wheel of the seeder, and the depth cannot be controlled, which easily leads to the tape getting tangled.

[0008] Based on the above issues, we have launched an integrated machine for corn-wheat intercropping, sowing, drip irrigation tape laying, and herbicide spraying. This machine mainly solves the above problems and completes sowing, fertilization, drip irrigation tape laying, and herbicide spraying in one operation. This machine can overcome the above problems and truly realize the efficient integration of corn strip intercropping and water and fertilizer integration technology, providing an feasible way to increase corn yield and improve land quality and efficiency.

[0016] The irregular gear has two sets of teeth, which are placed symmetrically at 180 degrees. The two sets of teeth have the same number of teeth and are named tooth one and tooth two, respectively.

[0017] A bending component is installed on the side wall of the tooth condition away from the mounting plate. The other end of the bending component is located at the top of the mounting frame. Multiple sets of actuating rods for driving are installed on the bottom wall of the end of the bending component located at the top of the mounting frame. The lower end of the actuating rod is movably mounted on the elastic screen to facilitate the screening of soil on the elastic screen.

[0018] Furthermore, a baffle is installed on the end of the connecting plate near the irregular gear, and the baffle has an air hole.

[0019] The side plate has a hydraulic rod installed on its sidewall, a support plate is movably installed on the lower outer sidewall of the side plate, a drive wheel is movably installed on the support plate, and the movable end of the hydraulic rod is movably connected to the support plate; the main beam has a back beam installed on its sidewall, a back crossbeam is installed on the back beam, and drip irrigation tape placement racks are installed at both ends of the back crossbeam for winding and placing drip irrigation tape, with the drip irrigation tape placement racks located on the upper end of the mounting frame; a front traction frame is installed at the front end of the back beam, and the front traction frame is connected to a drive device, such as a tractor.

[0020] In a preferred embodiment of the present invention, foot pedals are installed at both ends of the main beam, and the foot pedals are located at the lower end of the drip irrigation tape placement frame. Fertilizer boxes are installed on the upper walls at both ends of the main beam, and a medicine box is installed in the middle of the main beam. Multiple sets of front-mounted disc furrow openers are also installed on both sides of the lower end of the main beam. The cutting and laying device is located between two adjacent sets of front-mounted disc furrow openers. The output end of the fertilizer box is located at the rear end of the front-mounted disc furrow opener. When the front-mounted disc furrow opener tills the land, the organic fertilizer in the fertilizer box is discharged into the furrow opened by the front-mounted disc furrow opener.

[0021] The main beam has main connecting frames installed at both ends of its rear side. A sowing device and a fertilizer box are installed on the upper wall of the main connecting frame. The fertilizer box is located at the rear end of the sowing device and on one side of the sowing operation direction. A depth-limiting wheel, a rear-mounted disc furrow opener, and a soil-covering wheel are installed on the bottom wall of the main connecting frame. The rear-mounted disc furrow opener is located between the depth-limiting wheels, and the soil-covering wheel is located at the rear end of the rear-mounted disc furrow opener. The output end of the sowing device is located at the rear side of the rear-mounted disc furrow opener, and the output end of the fertilizer box is located at the rear side of the sowing device. The rear-mounted disc furrow opener opens furrows in the soil, and the sowing device sows the seeds in the furrows. At the same time, the fertilizer in the fertilizer box falls into the furrows, mainly providing nutrients for the seedlings and promoting root development.

[0022] Secondary connecting frames are also installed at both ends of the rear side of the main beam. The secondary connecting frames are located between the main connecting frames at the ends. A spraying device is installed at the rear end of the secondary connecting frames. The spraying device is connected to the medicine tank. The spraying device includes a sealed enclosure with an opening at the lower end and a nozzle inside the enclosure. The medicine in the medicine tank is sprayed onto the soil where corn is planted through the nozzle. During spraying, the enclosure forms a relatively sealed space to prevent the medicine from spreading to the planting area of ​​wheat or soybeans, thus enabling targeted spraying.

[0023] The beneficial effects of the present invention after adopting the above structure are as follows:

[0024] (1) It can realize staggered sowing of corn-wheat or corn-soybean, realize efficient intercropping of crops, and improve land utilization and utilization effect.

[0025] (2) The furrow opener can clear plant roots and stones on the land. The end of the drip irrigation tape placed on the drip irrigation tape placement frame moves through the mounting frame and through the through hole in sequence and is placed on the ground that has been furrowed at the bottom of the mounting frame. This can reduce the damage to the drip irrigation tape caused by stones and hard straw.

[0026] (3) Under the action of the driven gear, the irregular gear and the tooth condition, the tooth condition makes a reciprocating motion, and drives the lever to move through the bending part, which can screen the soil on the elastic screen. The soil screened by the installation frame falls onto the drip irrigation tape laid on the ground.

[0027] (4) When the tooth condition moves toward the push plate, it can squeeze the push plate. The push plate moves along the groove on the bottom wall of the connecting plate and squeezes the compression bladder. The gas in the compression bladder is transported to the second elastic bladder through the air guide tube, and the second elastic bladder bulges. When the tooth condition moves away from the push plate, the tooth condition can drive the push plate to move away from the baffle, and the external gas enters the compression bladder.

[0028] (5) When the elastic bladder and the folded bladder are filled with gas and lifted, the folded bladder can push the lifting plate to move up along the slot. After the lifting plate moves up, it stretches the elastic screen. The middle of the elastic screen is lifted, and the stones on the elastic screen roll down to both ends along the elastic screen, making it easier to discharge.

[0029] (6) The drip irrigation tape laying device is on the front main beam to reduce the impact of bumps on the depth of drip irrigation tape laying and make the burial depth of drip irrigation tape basically consistent.

[0030] (7) The pesticide in the pesticide tank is sprayed in a closed manner on the soil where corn is planted through the spraying device to prevent the pesticide from spreading to the planting area of ​​wheat or soybeans, and can achieve targeted spraying. Attached Figure Description

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0046] like Figures 1-11 As shown, a corn-wheat intercropping shallow-buried drip irrigation and closed-loop weeding staggered no-till planter includes a main beam 1 for support and fixation. A cutting and laying device 2 and an adjustment device 3 are installed on the main beam 1. The cutting and laying device 2 and the adjustment device 3 are each provided in two sets, respectively located at both ends of the main beam 1. The adjustment device 3 is located inside the cutting and laying device 2, and the adjustment device 3 is connected to the cutting and laying device 2 through.

[0047] The cutting and laying device 2 includes a mounting frame 4, which is mounted on the side wall of the main beam 1. A trencher 5 is installed at the lower end of the mounting frame 4 for clearing plant roots and stones from the soil. A mounting frame 6 is provided on the lower side wall of the mounting frame 4. A protective frame 7 is installed on the side of the mounting frame 6 connected to the mounting frame 4, and the protective frame 7 is located inside the mounting frame 6. A fixing plate 2 8 is installed on the bottom wall of the mounting frame 6. The fixing plate 2 8 has a cross-shaped structure, and a folding mechanism is installed on the upper wall of the fixing plate 2 8 located at the center of the mounting frame 6. The folded bladder 9 has a hollow cavity. A lifting plate 10 is installed at the upper end of the folded bladder 9. The lifting plate 10 is movably disposed within the bottom wall of the mounting frame 6. An elastic bladder 11 is installed on the upper wall of the fixing plates 8 at both ends of the mounting frame 6. The elastic bladder 11 has a frame-shaped structure with an internal cavity and is connected to the folded bladder 9. The vertical cross-section of the elastic bladder 11 is a fan-shaped structure, with a larger arc in the part connected to the folded bladder 9 and a smaller arc in the part connected to the mounting frame 6. The upper end of the elastic bladder 11 is an inclined structure.

[0048] The mounting frame 6 is a hollow structure with an open top. The front end of the mounting frame 6 is provided with an inlet 12, which is located at both ends of the trench opener 5. The soil generated when the trench opener 5 trenches enters the mounting frame 6 through the inlet 12. The bottom wall of the mounting frame 6 is provided with a discharge port 13. The screened soil falls onto the laid drip irrigation tape through the discharge port 13, burying the edges of the drip irrigation tape. The fixing plate 8 is located inside the discharge port 13. The left and right walls of the mounting frame 6 are provided with discharge ports 14, through which the screened stones are discharged. The protective frame 7 is provided with a through hole 15.

[0049] The cutting and laying device 2 also includes an elastic screen 16 and an elastic bladder 17. The elastic screen 16 is installed in the feed port 13 of the mounting frame 6 and is located at the lower end of the discharge port 14. The elastic screen 16 is connected to the upper end of the elastic bladder 11 and the side wall of the lifting plate 10 respectively.

[0050] The second elastic bladder 17 is located on one outer side wall of the mounting frame 6. The second elastic bladder 17 is sealed to the side wall of the mounting frame 6. The bottom inner wall of the mounting frame 6 is provided with a vent pipe 18. One end of the vent pipe 18 is connected to the inner space of the second elastic bladder 17, and the other end of the vent pipe 18 is connected to the folded bladder 9. A control valve is installed in the vent pipe 18 to facilitate the control of the gas flow in the second elastic bladder 17. The second elastic bladder 17 is provided with an exhaust valve to discharge the gas in the first elastic bladder 11, the folded bladder 9, and the second elastic bladder 17.

[0051] The side wall of the discharge port 13 is provided with a slot 19, and the movable end of the lifting plate 10 is equipped with a clamping plate 20, which is movably clamped in the slot 19.

[0052] It should be noted that initially, the elastic bladder 11 is in an unstressed state, and the lifting plate 10 is located inside the discharge port 13. When the gas in the elastic bladder 2 17 enters the folded bladder 9 and the elastic bladder 11 through the vent pipe 18, the elastic bladder 11 and the folded bladder 9 are filled with gas and lifted. The folded bladder 9 pushes the lifting plate 10 to move upward along the slot 19. After the lifting plate 10 moves upward, it stretches the elastic screen 16, and the middle of the elastic screen 16 is lifted. The stones or impurities on the elastic screen 16 roll down to both ends along the elastic screen 16 and are finally discharged from the discharge port 14.

[0053] The control device 3 includes a side plate 21, a first mounting plate 22, and a second mounting plate 23. The side plate 21, the first mounting plate 22, and the second mounting plate 23 are all located at the lower end of the main beam 1. A first fixing plate 24 is installed at the lower end of the side plate 21. A driven gear 25 is installed on the lower side wall of the first fixing plate 24. An irregular gear 26 is installed on the lower side wall of the first mounting plate 22. The irregular gear 26 meshes with the driven gear 25. A connecting plate 27 is also installed on the side wall of the first mounting plate 22. A sliding groove 28 is provided on the bottom wall of the connecting plate 27. A toothed conditioner 29 is movably installed in the sliding groove 28. The toothed conditioner 29 is located at the upper end of the driven gear 25 and the irregular gear 26, and meshes with both the driven gear 25 and the irregular gear 26. A motor 30 is installed at the lower end of the second mounting plate 23. The output end of the motor 30 is connected to the center of the irregular gear 26.

[0054] The irregular gear 26 is provided with two sets of teeth, which are placed symmetrically at 180 degrees. The two sets of teeth have the same number of teeth and are named tooth 1 31 and tooth 2 32 respectively.

[0055] It should be noted that, assuming the motor 30 drives the irregular gear 26 to rotate counterclockwise, the driven gear 25 and the tooth condition 29 are always in a meshed state. When tooth 31 begins to mesh with tooth condition 29, tooth 32 does not mesh with the driven gear 25. As the irregular gear 26 rotates, the teeth on tooth 31 mesh with tooth condition 29 one by one, and tooth condition 29 moves in one direction. When tooth condition 29 moves, it drives the driven gear 25, and the driven gear 25 rotates counterclockwise. When tooth 31 disengages from tooth condition 29, tooth 32 just meshes with the driven gear 25, driving the driven gear 25 to rotate clockwise. The driven gear 25 drives tooth condition 29 to move in another direction until tooth 32 disengages from the driven gear 25.

[0056] Driven by the motor 30, tooth 32 meshes with tooth condition 29. At this time, tooth 31 does not mesh with driven gear 25. As the irregular gear 26 rotates, the teeth on tooth 32 mesh with tooth condition 29 one by one. Tooth condition 29 moves in one direction and drives driven gear 25 during the movement. Driven gear 25 rotates counterclockwise. When tooth 32 disengages from tooth condition 29, tooth 31 meshes with driven gear 25, causing driven gear 25 to rotate clockwise. Driven gear 25 drives tooth condition 29 to move in another direction until tooth 31 disengages from driven gear 25 and meshes with tooth condition 29.

[0057] Under the action of driven gear 25 and irregular gear 26, gear condition 29 performs reciprocating motion.

[0058] A bending member 33 is installed on the side wall of the tooth condition 29 away from the mounting plate 22. The other end of the bending member 33 is located at the top of the mounting frame 6. Multiple sets of actuating rods 34 for driving are installed on the bottom wall of the end of the bending member 33 located at the top of the mounting frame 6. The lower end of the actuating rod 34 is movably mounted on the elastic screen 16 to facilitate the screening of the soil on the elastic screen 16.

[0059] It should be noted that when the tooth condition 29 moves back and forth, it drives the bending part 33 to move, and the bending part 33 drives the actuating rod 34 to move. The actuating rod 34 screens the soil on the elastic screen 16. When the actuating rod 34 moves back and forth, it can move to the bottom wall of the mounting frame 6 that is separated from the discharge port 13.

[0060] A baffle 35 is installed on one end of the connecting plate 27 near the irregular gear 26. The baffle 35 has an air hole. A pusher plate 36 is movably installed in the slide groove 28. A compression bladder 37 is provided between the baffle 35 and the pusher plate 36. A one-way valve is provided in the air hole to facilitate the entry of external gas into the compression bladder 37. A magnetic element one is provided on the outer wall of the pusher plate 36. A magnetic element two is provided on one end of the gear 29 near the pusher plate 36. The magnetic elements one and two have opposite magnetic properties. An air guide pipe 38 is installed on the connecting plate 27. One end of the air guide pipe 38 is connected to the compression bladder 37, and the other end of the air guide pipe 38 is connected to the elastic bladder 17. A one-way valve is provided in the air guide pipe 38 to facilitate the entry of gas from the compression bladder 37 into the elastic bladder 17.

[0061] It should be noted that when the tooth condition 29 moves towards the push plate 36, it can compress the push plate 36. The push plate 36 moves along the groove 28 on the bottom wall of the connecting plate 27, compressing the compression bladder 37. The gas in the compression bladder 37 is transported to the elastic bladder 17 through the air guide pipe 38. The control valve in the air pipe 18 is closed, and the elastic bladder 17 inflates. When the tooth condition 29 moves away from the push plate 36, it can drive the push plate 36 away from the baffle 35 through magnetic adsorption. The compression bladder 37 is stretched, and external gas enters the compression bladder 37 through the one-way valve.

[0062] A hydraulic rod 39 is installed on the side wall of the side plate 21. A support plate 40 is movably installed on the lower outer wall of the side plate 21.

Drip irrigation tape placement racks 44 are installed at both ends of the back crossbeam 43 for winding and placing drip irrigation tape. The drip irrigation tape placement rack 44 is located at the upper end of the mounting frame 4. The end of the drip irrigation tape placed on the drip irrigation tape placement rack 44 moves through the mounting frame 4 and the through hole 15 in sequence and is placed on the trenched ground at the lower end of the mounting frame 6. The soil screened by the mounting frame 6 falls onto the drip irrigation tape laid on the ground. A front traction frame 45 is installed at the front end of the back beam 42. The front traction frame 45 is connected to the drive equipment, such as a tractor.

[0063] Foot pedals 46 are installed at both ends of the main beam 1. The foot pedals 46 are located at the lower end of the drip irrigation tape placement frame 44. Fertilizer boxes 47 are installed on the upper walls of both ends of the main beam 1. A medicine box 48 is installed in the middle of the main beam 1. Multiple sets of front-mounted disc furrow openers 49 are also installed on both sides of the lower end of the main beam 1. The cutting and laying device 2 is located between two adjacent sets of front-mounted disc furrow openers 49. The output end of the fertilizer box 47 is located at the rear end of the front-mounted disc furrow opener 49. When the front-mounted disc furrow opener 49 tills the land, the organic fertilizer in the fertilizer box 47 is discharged into the furrow opened by the front-mounted disc furrow opener 49.

[0064] The main beam 1 has main connecting frames 50 installed at both ends of its rear side. The main connecting frame 50 has a sowing device 51 and a fertilizer box 52 installed on its upper wall.

The rear disc furrow opener 54 opens furrows in the soil. The sowing device 51 sows the seeds in the furrows. At the same time, the fertilizer in the fertilizer box 52 falls onto the side of the furrows at a certain distance from the corn seeds. It mainly provides nutrients for the seedling stage and promotes root development.

[0065] The main beam 1 is also equipped with auxiliary connecting frames 56 at both ends of the rear side. The auxiliary connecting frames 56 are located between the main connecting frames 50 at the ends. The rear end of the auxiliary connecting frames 56 is equipped with a spraying device 57. The spraying device 57 is connected to the medicine box 48. The spraying device 57 includes a sealing enclosure with an opening at the lower end and a nozzle inside the enclosure.

[0066] The specific usage is as follows:

[0067] The front traction frame 45 is connected to the drive equipment. The hydraulic rod 39 drives the drive wheel 41. The position of the drive wheel 41 is adjusted so that the front disc furrow opener 49, furrow opener 5, depth limiting wheel 53, rear disc furrow opener 54 and soil covering wheel 55 can all work. The end of the drip irrigation tape moves through the mounting frame 4 and the through hole 15 in sequence and is placed on the already furrowed ground at the lower end of the mounting frame 6. The drip irrigation tape placed on the field ridge is fixed by the pressure of the heavy object. When the equipment moves, the front disc furrow opener 49 tills the land. The organic fertilizer in the fertilizer box 47 is discharged into the furrow opened by the front disc furrow opener 49. The furrow opener 5 cleans the plant roots and stones on the ground. The drip irrigation tape is laid from the drip irrigation tape placement frame 44 to the furrowed ground under the action of friction. The rear disc furrow opener 54 furrows the land.

[0068] Then, the sowing device 51 sows the seeds in the furrows, and at the same time, the fertilizer in the fertilizer box 52 falls into the furrows to provide nutrients for the seedlings and promote root development. During the wheat planting season, wheat can be sown through this device, and during the corn planting season, corn can be sown through this device. During the planting season of other crops, sowing can also be carried out through this device. It can realize staggered sowing of corn-wheat or corn-soybeans, realize efficient intercropping of crops, and improve land utilization and utilization efficiency.

[0069] The pesticide in the pesticide tank 48 is sprayed onto the soil where corn is planted through the nozzle. During spraying, the enclosure forms a relatively closed space to prevent the pesticide from spreading to the planting area of ​​wheat or soybeans, thus enabling targeted spraying.

[0070] When the trencher 5 is trenching, some of the soil produced enters the mounting frame 6 through the inlet 12, and the soil is eventually pushed onto the screen.

[0071] Initially, the elastic bladder 11 is in an unstressed state, and the lifting plate 10 is located inside the discharge port 13;

[0072] When the motor 30 works, it drives the gear condition 29 to make a reciprocating motion. When the gear condition 29 makes a reciprocating motion, it drives the bending part 33 to move. The bending part 33 drives the actuating rod 34 to move. The actuating rod 34 screens the soil on the screen. The soil screened by the mounting frame 6 falls onto the drip irrigation tape laid on the ground.

[0073] When the tooth condition 29 moves toward the push plate 36, the push plate 36 compresses the compression bladder 37. The gas inside the compression bladder 37 is transported to the elastic bladder 17 through the air pipe 38. The control valve in the air pipe 18 and the exhaust valve in the elastic bladder 17 are both closed, and the elastic bladder 17 inflates. When the tooth condition 29 moves away from the push plate 36, the tooth condition 29 can drive the push plate 36 to move away from the baffle 35 through magnetic adsorption. The compression bladder 37 is stretched, and external gas enters the compression bladder 37 through the one-way valve.

[0074] After the teeth condition 29 has been used for several rounds, the control valve in the vent pipe 18 is opened. The gas in the second elastic bladder 17 enters the folded bladder 9 and the first elastic bladder 11 through the vent pipe 18. The first elastic bladder 11 and the folded bladder 9 are filled with gas and lifted. The folded bladder 9 pushes the lifting plate 10 to move upward along the slot 19. After the lifting plate 10 moves upward, it stretches the screen. The middle of the screen is lifted, and the stones on the screen roll down to both ends along the screen and are finally discharged from the outlet 14. Then the exhaust valve in the second elastic bladder 17 is opened, which can discharge the gas in the first elastic bladder 11, the folded bladder 9 and the second elastic bladder 17. Then the control valve in the vent pipe 18 and the exhaust valve in the second elastic bladder 17 are closed.
