Description

Technical Field

[0001] The present invention relates to the technical field of intercropping and sowing of corn and legume crops, and in particular to an integrated machine for intercropping, fertilizing, sowing and weeding of corn and legume crops. Background Art

[0002] Intercropping (including inter-ridge planting) refers to the practice of planting two or more crops alternately in rows or strips on the same field during the same growing season. Intercropping improves land utilization. The resulting crop complex increases sunlight interception and absorption, reducing light energy waste. Furthermore, the two crops can complement each other. Planting legumes between corn ridges protects the soil, fixes nitrogen, improves soil fertility, and effectively reduces fertilizer consumption, making it a novel ecological planting model.

[0003] When intercropping corn with legumes or sowing between ridges, since herbicides for corn and legumes are mutually exclusive, applying one herbicide after seedling emergence will inhibit the growth of the other, necessitating separate herbicide spraying. Existing technologies make it difficult to control weeds with herbicides, as weeding is mostly manual, time-consuming, labor-intensive, and costly. Mechanization is not feasible, making it unsuitable for large-scale planting and inconsistent with the requirements of modern agricultural development. However, herbicides suitable for the sowing period do not mutually exclude seeds, so rotary tillage and herbicide spraying should be performed simultaneously during sowing. This mixing of the herbicide with the soil reduces the potential for photolysis caused by surface spraying and improves its efficacy. This integrated sowing, fertilization, and pesticide application system addresses the difficulty of controlling weeds in intercropping corn with legumes and in systems where corn is planted between ridges and legumes.

[0004] In response to the above problems, there is an urgent need to develop an integrated fertilizing, sowing and weeding machine suitable for intercropping corn and legumes and planting legumes between corn cages. Summary of the Invention

[0005] The present invention proposes an integrated machine for intercropping corn and legume crops and planting legume crops between corn cages for fertilizing, sowing and weeding, which solves the problem of time-consuming and labor-intensive manual weeding in related technologies.

[0006] The technical solution of the present invention is as follows: an integrated machine for intercropping corn and leguminous crops for fertilization, sowing and weeding, comprising a frame and a rotary tillage mechanism, a fertilization mechanism and a sowing mechanism sequentially arranged on the frame.

[0007] The rotary tillage mechanism includes a hollow shaft, a rotary tillage blade, a rotary joint, a tube body and a herbicide box, the hollow shaft is rotatably arranged on the frame, the rotary tillage blades are multiple and are arranged on the circumferential surface of the hollow shaft, the herbicide box is arranged on the frame for storing liquid medicine, the tube body is arranged on the frame and is connected to the herbicide box, the tail end of the rotary joint is rotatably connected to the end of the tube body, a baffle is arranged in the hollow shaft, the head end of the rotary joint penetrates into the hollow shaft and abuts against the baffle, the baffle and the end surface of the rotary joint are provided with a liquid outlet, the tube body, the rotary joint and the hollow shaft are coaxially arranged and connected in sequence, and the circumferential surface of the hollow shaft is provided with multiple atomizing nozzles.

[0008] The circumference of the baffle plate is provided with a driving block and a stopping block, and the outer circle of the rotary joint is provided with a shift block, and the shift block rotates between the driving block and the stopping block. When the shift block abuts against the driving block, the baffle plate and the liquid outlet on the end face of the rotary joint are connected. When the shift block abuts against the stopping block, the baffle plate and the liquid outlet on the end face of the rotary joint are disconnected.

[0009] As a further technical solution,

[0010] It also includes a reset mechanism, which includes a driving member, a ring gear and a gear. The driving member is installed on the inner wall of the hollow shaft, the ring gear is sleeved on the outer circle of the rotary joint, the gear is rotatably arranged on the inner wall of the hollow shaft, the gear is engaged with the ring gear, and the driving member is connected to the gear.

[0011] As a further technical solution,

[0012] The liquid outlet is circular and multiple liquid outlets are arranged along the circumferential direction.

[0013] As a further technical solution,

[0014] The frame is provided with a baffle, and the baffle is located above the hollow rotating shaft.

[0015] As a further technical solution,

[0016] The baffle is arranged on the frame in a vertical sliding manner, and one end of the baffle away from the traveling direction is inclined downward. The frame is provided with a soil raising mechanism for raising the turned soil onto the baffle.

[0017] As a further technical solution,

[0018] The soil-lifting mechanism includes a conveying chain, a supporting plate and a baffle. The conveying chain is installed on the frame and is located behind the hollow rotating shaft. There are multiple supporting plates, all of which are hinged to the conveying chain by means of torsion springs. The torsion springs are used to provide a force to keep the supporting plates horizontal. The baffle is provided on the frame and located above the baffle. The baffle is located on the moving path of the supporting plate and is used to squeeze the free end of the supporting plate to make it swing downward.

[0019] As a further technical solution,

[0020] An eccentric wheel is rotatably provided on the frame, the eccentric wheel abuts against the bottom surface of the baffle, and the eccentric wheel is driven and connected to the hollow rotating shaft by means of a transmission belt.

The sowing boxes are divided into corn seed bins and legume seed bins by partitions. The slides are slidably arranged at the connection between the sowing boxes and the seeders, and are used to control the opening and closing of the corn seed bins and the legume seed bin outlets.

[0023] The working principle and beneficial effects of the present invention are as follows: in order to replace manual weeding, a herbicide box is set on a frame, and the medicine liquid is connected to the hollow rotating shaft with the help of a pipe body and a rotary joint, and then the medicine liquid is sprayed out with the help of an atomizing nozzle as the hollow rotating shaft rotates, thereby realizing automatic spraying of the herbicide, and the spraying action is carried out synchronously with the rotation of the hollow rotating shaft. A plurality of rotary tillage blades are set on the circumference of the hollow rotating shaft, and the rotary tillage blades turn the soil, so that the medicine liquid can be fully mixed with the soil as the soil is turned, thereby maximizing the weed control effect of the medicine liquid. The on-off state is controlled by the liquid outlet on the rotary joint and the baffle. Under normal conditions, the shift block abuts the stop block, at which point the liquid outlet on the rotary joint and the baffle are staggered, and the internal passage is disconnected. During operation, the frame descends as a whole, allowing the rotary tillage blade to penetrate the soil. The hollow shaft then drives the rotary tillage blade to rotate, causing the baffle and the rotary joint to twist relative to each other, causing the shift block to disengage from the stop block and abut against the drive block. After abutment, the rotary joint and the baffle are connected. As the hollow shaft continues to rotate, the shift block remains in abutment with the drive block and rotates accordingly, thereby driving the rotary joint to rotate, ensuring that the liquid outlet remains connected during the rotary tillage process. The liquid medicine enters the hollow shaft and is sprayed out through the atomizing nozzle. The rotation of the hollow shaft can also control the connection of the liquid outlet, achieving automatic spraying of the liquid medicine after rotary tillage begins, thus playing a linkage role.

[0024] The present invention pours liquid medicine into the hollow rotating shaft through the tube body and the rotary joint, and sprays it out through the atomizing nozzle, thereby realizing automatic spraying of the herbicide, replacing manual labor and improving efficiency. In addition, a fertilizing mechanism and a sowing mechanism are arranged at the rear to realize machine integration. By designing the rotating shaft to be hollow and installing the atomizing nozzle on the hollow rotating shaft, rotary tillage and herbicide spraying can be carried out synchronously. The soil is turned over by rotary tillage, and the liquid medicine is sprayed into the soil, thereby realizing full mixing of the liquid medicine and the soil, and maximizing the weed control effect of the liquid medicine.

DETAILED DESCRIPTION

[0036] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1 to 9 As shown, this embodiment proposes an integrated machine for intercropping corn and leguminous crops for fertilization, sowing and weeding, comprising a frame 1 and a rotary tillage mechanism 2, a fertilization mechanism 3 and a sowing mechanism 4 sequentially arranged on the frame 1.

[0038] The rotary tillage mechanism 2 includes a hollow shaft 5, a rotary tillage blade 6, a rotary joint 7, a pipe body 8 and a herbicide box 9. The hollow shaft 5 is rotatably arranged on the frame 1. The rotary tillage blade 6 is multiple and is arranged on the circumferential surface of the hollow shaft 5. The herbicide box 9 is arranged on the frame 1 for storing liquid medicine. The pipe body 8 is arranged on the frame 1 and is connected to the herbicide box 9. The tail end of the rotary joint 7 is rotatably connected to the end of the pipe body 8. A baffle 10 is provided in the hollow shaft 5. The head end of the rotary joint 7 penetrates into the hollow shaft 5 and abuts against the baffle 10. The baffle 10 and the end surface of the rotary joint 7 both have a liquid outlet 11. The pipe body 8, the rotary joint 7 and the hollow shaft 5 are coaxially arranged and connected in sequence. A plurality of atomizing nozzles 12 are provided on the circumferential surface of the hollow shaft 5.

[0039] The baffle plate 10 has a driving block 13 and a stopping block 14 on its circumference, and the rotary joint 7 has a shift block 15 on its outer circumference. The shift block 15 rotates between the driving block 13 and the stopping block 14. When the shift block 15 abuts against the driving block 13, the baffle plate 10 and the liquid outlet 11 on the end face of the rotary joint 7 are connected. When the shift block 15 abuts against the stopping block 14, the baffle plate 10 and the liquid outlet 11 on the end face of the rotary joint 7 are disconnected.

[0040] In this embodiment, in order to replace manual automatic spraying of herbicides, a herbicide box 9 is set on the frame 1, and the liquid medicine is connected to the hollow shaft 5 with the help of the tube body 8 and the rotary joint 7, and then the liquid medicine is sprayed out with the rotation of the hollow shaft 5 with the help of the atomizing nozzle 12, thereby realizing automatic spraying of herbicides, and the spraying action is carried out synchronously with the rotation of the hollow shaft 5. A plurality of rotary tillage blades 6 are set on the circumference of the hollow shaft 5, and the rotary tillage blades 6 turn the soil, so that the liquid medicine can be fully mixed with the soil as the soil is turned, thereby maximizing the weed control effect of the liquid medicine. The on-off state is controlled by the liquid outlet 11 on the rotary joint 7 and the baffle plate 10. In a normal state, the dial block 15 abuts against the stop block 14. At this time, the liquid outlet 11 on the rotary joint 7 and the baffle plate 10 is staggered, and the internal passage is in a disconnected state. During operation, the frame 1 descends as a whole, so that the rotary tillage blade 6 is inserted into the soil, and then the hollow shaft 5 drives the rotary tillage blade 6 to rotate, so that the baffle plate 10 and the rotary joint 7 produce relative torsion, so that the dial block 15 disengages from the stop block 14 and abuts against the driving block 13. After abutting, the rotary joint 7 and the liquid outlet 11 of the baffle plate 10 are connected. As the hollow shaft 5 continues to rotate, the dial block 15 remains in the state of abutting the driving block 13 and follows the rotation, thereby driving the rotary joint 7 to rotate, so that the liquid outlet 11 can always remain connected during the rotary tillage process, and the liquid medicine enters the hollow shaft 5 and is sprayed out through the atomizing nozzle 12. Furthermore, the connection of the liquid outlet 11 can be controlled by the rotation of the hollow rotating shaft 5, so that the automatic spraying of the liquid medicine after the rotary tillage starts is realized, thus playing a linkage role.

[0041] In this embodiment, the liquid medicine is poured into the hollow rotating shaft 5 through the tube body 8 and the rotary joint 7, and is sprayed out by the atomizing nozzle 12, so as to realize automatic spraying of the herbicide, replace manual labor, and improve efficiency. In addition, a fertilizing mechanism 3 and a sowing mechanism 4 are arranged at the rear to realize machine integration. By designing the rotating shaft to be hollow and installing the atomizing nozzle 12 on the hollow rotating shaft 5, rotary tillage and herbicide spraying can be carried out synchronously. The soil is turned over by rotary tillage, and the liquid medicine is sprayed into the soil, so that the liquid medicine and the soil are fully mixed, and the weed control effect of the liquid medicine is maximized.

[0042] Furthermore, it also includes,

[0043] It also includes a reset mechanism, which includes a driving member 16, a ring gear 17 and a gear 18. The driving member 16 is installed on the inner wall of the hollow shaft 5, the ring gear 17 is sleeved on the outer circle of the rotary joint 7, and the gear 18 is rotatably arranged on the inner wall of the hollow shaft 5. The gear 18 is engaged with the ring gear 17, and the driving member 16 is driven and connected to the gear 18.

[0044] In this embodiment, when the tillage is completed, a reset mechanism is provided to allow the shift block 15 to re-abut against the stop block 14 and disconnect the liquid outlet 11. When the tillage is completed, the driving member 16 drives the gear 18 to rotate, and the gear 18 engages with the ring gear 17, controlling the rotary joint 7 to produce a certain angle of twisting, so that the shift block 15 disengages from the driving block 13 and abuts against the stop block 14, disconnecting the liquid outlet 11, thereby realizing automatic cessation of liquid spraying after the tillage is completed.

[0045] Furthermore, it also includes,

[0046] The liquid outlet 11 is circular and multiple liquid outlets 11 are arranged along the circumferential direction.

[0047] In this embodiment, in order to ensure sufficient flow of the liquid medicine and facilitate the flow of the liquid medicine, the liquid outlet 11 is designed to be circular, and multiple outlets are provided in the circumferential direction to ensure the flow rate.

[0048] Furthermore,

[0049] The frame 1 is provided with a baffle 19 , and the baffle 19 is located above the hollow rotating shaft 5 .

[0050] In this embodiment, in order to avoid the waste of liquid medicine when the atomizing nozzle 12 rotates upward with the hollow shaft 5, a baffle 19 is provided above the hollow shaft 5 to block the upward spraying of the liquid medicine. After the liquid medicine is sprayed onto the baffle 19, it will drip into the soil below to avoid waste.

[0051] Furthermore,

[0052] The baffle 19 is vertically slidably arranged on the frame 1 , and one end of the baffle 19 away from the traveling direction is tilted downward. The frame 1 is provided with a soil-raising mechanism for raising the turned-up soil onto the baffle 19 .

[0053] In this embodiment, a soil-lifting mechanism is also provided. During rotary tillage, the tilling blades 6 lift the soil backward. The lifted soil is then collected by the soil-lifting mechanism and transported to the baffle 19. The baffle 19 can slide back and forth vertically. The end of the baffle 19, facing away from the direction of travel, tilts downward. The reciprocating sliding motion generates vibrations that shake the soil down, thereby achieving a delayed drop of the soil. The drop point is located behind the hollow rotating shaft 5. After rotary tillage is completed, a layer of soil is shaken down by the baffle 19, covering the surface of the soil mixed with the liquid medicine, thereby covering and sealing the soil and further increasing the depth of action of the liquid medicine.

[0054] Furthermore,

[0055] The soil-lifting mechanism includes a conveying chain 20, a supporting plate 21 and a stopper 22. The conveying chain 20 is installed on the frame 1 and is located behind the hollow rotating shaft 5. There are multiple supporting plates 21, all of which are hinged to the conveying chain 20 by means of torsion springs. The torsion springs are used to provide a force to keep the supporting plates 21 horizontal. The stopper 22 is provided on the frame 1 and is located above the baffle 19. The stopper 22 is located on the moving path of the supporting plate 21 and is used to squeeze the free end of the supporting plate 21 to make it swing downward.

[0056] In this embodiment, the conveyor chain 20 is arranged on a vertical plane, and a plurality of supporting plates 21 are installed on the conveyor chain 20. The supporting plates 21 are located behind the hollow rotating shaft 5. After the rotary tillage blades 6 lift up a portion of the soil, the soil will fall onto the supporting plates 21 and be transported upward through the conveyor chain 20. The supporting plates 21 are maintained in a horizontal state by means of torsion springs. When the conveyor chain 20 drives the supporting plates 21 to move to the stopper 22, the stopper 22 abuts against the free end of the supporting plate 21 and squeezes downward, causing the free end of the supporting plate 21 to swing downward, thereby causing the supported soil to fall onto the baffle 19. The conveyor chain 20 is arranged at an angle, with the top end of the conveyor chain 20 offset forward and the bottom end offset backward, so that the top end of the conveyor chain 20 can be located above the baffle 19, so that the soil can accurately fall onto the baffle 19.

[0057] Furthermore, it also includes,

[0058] An eccentric wheel 23 is rotatably provided on the frame 1 , and the eccentric wheel 23 abuts against the bottom surface of the baffle 19 . The eccentric wheel 23 is driven and connected to the hollow shaft 5 by a transmission belt.

[0059] In this embodiment, the eccentric wheel 23 is driven to rotate by the hollow shaft 5. The eccentric wheel 23 is located below the baffle 19 and abuts the ground of the baffle 19. After the eccentric wheel 23 rotates, it pushes the baffle 19 upward and back and forth, so that the baffle 19 slides back and forth vertically, thereby generating a vibration effect. The vibration of the baffle 19 is controlled by driving the eccentric wheel 23 by the hollow shaft 5, so that the hollow shaft 5 can simultaneously play the role of rotary tillage and vibrating the baffle 19, achieving a linkage effect.

[0060] Furthermore, it also includes,

[0061] The sowing mechanism 4 includes multiple groups of sowing boxes 24, seeders 25 and slides 26. The sowing boxes 24 are connected to the seeders 25. The sowing boxes 24 are divided into corn seed bins 27 and legume seed bins 28 by means of partitions. The slides 26 are slidably arranged at the connection between the sowing boxes 24 and the seeders 25, and are used to control the opening and closing of the outlets of the corn seed bins 27 and the legume seed bins 28.

[0062] In this embodiment, to enable rapid switching of crop types during intercropping, a partition is installed inside the seeding box 24, dividing the seeding box 24 into a corn seed bin 27 and a legume seed bin 28, which store corn seeds and legume seeds, respectively. A slide 26 is used to control the opening and closing of the outlets of the corn seed bin 27 and the legume seed bin 28. The slide 26 has a toggle lever that extends out of the seeding box 24 for easy operation. Sliding the slide 26 to one side allows a separate bin to connect to the seeder 25, enabling normal seeding. When it is necessary to switch crop types, the slide 26 is toggled and slid to the other side to connect the other bin to the seeder 25. Operation is simple, convenient, and fast.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
