Description

Technical Field

[0001] The invention relates to the technical field of agricultural fertilization, in particular to a fixed-point in-depth fertilization device suitable for intercropping of cereals and beans. Background Art

[0002] Intercropping of gramineous crops (such as corn, wheat, etc.) and legume crops (such as soybeans, mung beans, etc.) can make full use of soil nutrients and space resources at different levels. Gramineous crops have deep root systems and mainly absorb nutrients from deep soil, while legume crops have relatively shallow root systems and can use nutrients from shallow soil. At the same time, legume crops have the function of nitrogen fixation and can convert nitrogen in the air into nitrogen that can be used by plants, thus providing part of the nitrogen source for gramineous crops and reducing the application of nitrogen fertilizers.

[0003] In conjunction with the above content, it should be noted that: Chinese patent publication number CN117598080A discloses an agricultural planting deep fertilization device, which realizes deep fertilization by inserting a fertilizer pipe directly into the soil. The vertical downward pressing process requires a deviation from the root position of the plant, resulting in a deviation in the fertilization point;

[0004] The Chinese patent with publication number CN117296500A discloses an integrated machine for ploughing, land preparation, multi-layer fertilization and sowing of intercropping of wheat and beans, which integrates ploughing, land preparation, fertilization and sowing. However, due to the limitation of the main body structure and the influence of different growth states of intercropping of wheat and beans, it is easy to cause the above equipment to fail to effectively carry out fixed-point, layered and in-depth fertilization according to the height difference of the rhizomes of wheat and beans after the growth of wheat and bean seedlings.

[0005] In view of the above-mentioned technical defects, a solution is now proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a fixed-point deep-drilling fertilization device suitable for intercropping of grass beans. The device uses a shallow-inserted fertilization frame to perform a uniform and quick soil-breaking and trench-pulling shallow soil fertilization treatment on grass beans in a seedling state, which helps rainwater and artificial watering to penetrate along the gullies, allowing the grass bean seedlings to fully absorb fertilizers, and keeps the soil for planting grass beans loose, so that the soil at the edge of the root and stem of the grass bean seedlings can gather water using the gullies, which helps to ensure the growth requirements of the grass bean seedlings in the early stage of planting.

[0007] And by utilizing the position deviation when the oblique insertion fertilization rack and the shallow insertion fertilization rack are running synchronously, a double-row synchronous fertilization action process is formed, which can not only pierce the soil in the root and rhizome area of ​​the grass plants for fertilization, but also cooperate with the shallow insertion fertilization rack to implement coordinated fertilization treatment for intercropping of grass and beans in the same row to solve the problems raised.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a fixed-point in-depth fertilization device suitable for intercropping of rice and beans, comprising a connecting beam, a diversion guide column is arranged on the top of one side of the connecting beam, and a diversion pipe is arranged on the inner wall of the middle part of the diversion guide column, a lifting hydraulic column connected to the connecting beam is arranged at the bottom of one side of the diversion guide column, a cylinder rod is arranged on the side of the lifting hydraulic column, and multiple groups of shallow insertion fertilization racks are arranged on the cylinder rod, a driving motor is arranged on the outer side of the middle part of the shallow insertion fertilization rack, and a storage pressure bag is arranged below the driving motor;

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 5 As shown, this embodiment is a fixed-point in-depth fertilization device suitable for intercropping of rice and beans, including a connecting beam 1, a shunt guide column 3 is arranged on the top of one side of the connecting beam 1, and a shunt pipe 302 is arranged on the inner wall of the middle part of the shunt guide column 3, a lifting hydraulic column 2 connected to the connecting beam 1 is arranged at the bottom of one side of the shunt guide column 3, a cylinder rod 202 is arranged on the side of the lifting hydraulic column 2, and a plurality of groups of shallow insertion fertilizer racks 5 are arranged on the cylinder rod 202, a driving motor 507 is arranged on the outer side of the middle part of the shallow insertion fertilizer rack 5, and a storage pressure bag 503 is arranged below the driving motor 507;

[0034] An upper beam frame 101 is arranged at the center of the top of the connecting beam body 1, and multiple sets of wheel assembly mounting frames 103 are symmetrically arranged on the sides of both ends of the connecting beam body 1, and multiple sets of limit blocks 104 are arranged on the surface of one side of the connecting beam body 1; an external valve 301 connected to the shunt pipe 302 is arranged through the outer wall of the middle part of the shunt guide column 3, and multiple sets of connecting valves 303 are arranged on the surface of the shunt pipe 302; a support rod 201 is sleeved on one side of the lifting hydraulic column 2, and a rotary hydraulic cylinder 204 connected to the barrel rod 202 is arranged on the rod body of the support rod 201, and a limit groove 203 is arranged on the surface of the barrel rod 202;

[0035] Fertilization at the seedling stage: the connecting beam body 1 is connected to the agricultural machinery through the upper beam frame 101, and the agricultural machinery pulls the fertilization device into the intercropped field of rice and beans;

[0036] The lifting hydraulic column 2 is adjusted according to the height of the seedlings. The lifting hydraulic column 2 drives the cylinder rod 202 to slide up and down through the support rod 201. The cylinder rod 202 synchronously drives the shallow insertion fertilizer frame 5 to adjust close to the field soil until the plow cone 501 of the shallow insertion fertilizer frame 5 is partially inserted into the soil. With the traction of the agricultural machinery, the plow cone 501 moves and scratches the soil in the field to form a slender fertilizer track. The plow cone 501 is a crescent arc structure, and the side facing the soil is a conical structure;

[0037] A plow cone 501 is provided at the bottom of the shallow insertion fertilizer rack 5, and a material injection port 508 is provided on one side of the plow cone 501. As the plow cone 501 breaks the soil, the external valve 301 is connected to the fertilizer storage box on the agricultural machinery, and the fertilizer liquid is guided to flow along the external valve 301, the shunt pipe 302, the connecting valve 303 and the material injection port 508, so as to achieve synchronous perfusion of the fertilizer liquid into the soil, thereby fertilizing the bean seedlings with a small height difference in the seedling state;

[0038] Example 2: Please refer to Figure 3 - Figure 5 As shown, the height difference of the root and stem growth of the bean plant is:

[0039] The shallow insertion fertilizer rack 5 is provided with a limiting hoop 506 sleeved with the barrel rod 202 on the outside, a connecting hose 504 is provided on the top of the shallow insertion fertilizer rack 5, and a regulating valve 505 is provided below the connecting hose 504, and an arc groove 502 connected to the storage pressure bag 503 is recessed on one side of the shallow insertion fertilizer rack 5;

[0040] Bean fertilization: After the agricultural machinery pulls the fertilizer device into the field, it drives in the gullies on both sides of the bean plant field due to the height of the agricultural machinery wheels, and the agricultural machinery moves slowly above the bean plants;

[0041] When the shallow-insertion fertilizer rack 5 moves close to the top of the single-row bean plants, the rotary hydraulic cylinder 204 first drives the shallow-insertion fertilizer rack 5 to deflect 45°±10 clockwise, and specifically adjusts it according to actual needs, so that the height of the plow cone 501 is close to the area below the barrel 202, and the lifting hydraulic column 2 drives the barrel 202 to slide down until the plow cone 501 of the shallow-insertion fertilizer rack 5 is close to the soil, and the rotary hydraulic cylinder 204 synchronously drives the shallow-insertion fertilizer rack 5 to rotate counterclockwise, so that the shallow-insertion fertilizer rack 5 is driven by the dual drive of the rotary hydraulic cylinder 204 and the lifting hydraulic cylinder to move along an arc trajectory and insert into the soil, so that an arc-shaped water storage tank is broken on the soil surface;

[0042] The servo motor 407 is started, and a gear connected to the surface of the shallow insertion fertilizer rack 5 is provided at the output end of the servo motor 407, and a tooth groove 2 is provided on the surface of the shallow insertion fertilizer rack 5 close to the servo motor 407. The shallow insertion fertilizer rack 5 is driven to slide downward between the limiting hoop 506 and the limiting groove 203, and combined with the piercing of the soil by the plow cone 501, the shallow insertion fertilizer rack 5 is inserted into the area below the root of the bean plant, which helps the bean plant to quickly absorb the fertilizer solution;

[0043] Before using the shallow insertion fertilizer rack 5, the storage pressure bag 503 is adjusted according to the root height and fertilization depth of the bean plant in this period of time. A lock buckle that is engaged with the arc groove 502 is arranged on the top of the storage pressure bag 503, so that the storage pressure bag 503 can be limited on the arc groove 502 according to the fertilization depth. The storage pressure bag 503 is kept connected with the storage pressure bag 503 through the regulating valve 505, and a check valve is arranged between the regulating valve 505 and the storage pressure bag 503. The fertilizer rack 5 is operated once, and the regulating valve 505 injects a quantitative fertilizer solution into the storage pressure bag 503. As the shallow insertion fertilizer rack 5 is inserted into the soil and gradually sinks into the soil, a pipeline connected to the discharge port 1 is provided at the bottom of the storage pressure bag 503. The storage pressure bag 503 gradually approaches the soil surface until it is squeezed, thereby pushing the fertilizer solution inside it into the injection port 508, and the injection port 508 guides it to be poured into the required fertilization area.

[0044] Example 3: Please refer to Figure 6 - Fig. 9 As shown, a sliding guide frame 102 is provided on the other side of the connecting beam body 1, and a guide limit column 4 and a push base 7 are respectively provided on the top of both ends of the sliding guide frame 102, an extension beam 403 is provided inside the guide limit column 4, and a plurality of groups of obliquely inserted fertilizer racks 6 are sleeved in the middle of the extension beam 403, and a material storage pressure bag 601 is provided at the bottom of the obliquely inserted fertilizer rack 6;

[0045] Grain fertilization: A lifting hydraulic cylinder 701 is provided on the top of the pushing base 7, and a rotating kit is provided on the top of the lifting hydraulic cylinder 701 which is sleeved with the bottom of the extension beam 403. The obliquely inserted fertilizer frame 6 and the shallowly inserted fertilizer frame 5 are used synchronously. In this state, the agricultural machinery drives the fertilization device to remain in place. A stepper motor connected to the sliding guide frame 102 is provided inside the pushing base 7. The stepper motor drives the pushing base 7 to move along the surface of the sliding guide frame 102, and the moving base drives the extension beam 403 to move toward one end of the guide limit column 4 through the rotating kit 702. The lifting slider 402 is slidably connected with the side groove 406, and guides the extension beam 403 toward the soil area of ​​the grain plant. There is a certain gap between the obliquely inserted fertilizer frame 6 and the shallowly inserted fertilizer frame 5, so that when the shallowly inserted fertilizer frame 5 is located above the bean plant, the obliquely inserted fertilizer frame 6 is located between the grain plants in the same row of the bean plant and the previous row of grain plants, and is close to the rhizome area of ​​the grain plants in the same row;

[0046] When the extension beam 403 slides close to the grass plant, the auxiliary wheel 404 first contacts the soil surface to guide the extension beam 403 to slide. During the sliding period, the lifting hydraulic cylinder 401 adjusts the height of one end of the extension beam 403 through the lifting slider 402 to keep the auxiliary wheel 404 moving along the soil surface. The auxiliary wheel 404 and the extension beam 403 are both made of metal. The lifting hydraulic cylinder 701 drives the other end of the extension beam 403 to slide up and down through the rotating kit, and uses the lifting slider 402 as a lever support point to adjust the extension angle of the extension beam 403. A guide wheel embedded in the inner contact of the side groove 406 is provided in the middle of the inner wall of the lifting slider 402;

[0047] When the extension beam 403 moves to the specified position, the output end of the servo motor 407 is provided with a gear connected to the tooth groove 1 606, and the obliquely inserted fertilizer rack 6 is driven to slide down along the inside of the central groove 405, and its bottom is first inserted into the soil of the grass plant, and is continuously driven by the servo motor 407 to penetrate into the soil until the injection port 2 605 penetrates into the soil required for fertilization;

[0048] Before the obliquely inserted fertilizer rack 6 is used, the height of the second storage pressure bag 601 on the connecting groove 603 is adjusted according to the required depth of fertilization of the grass plants, and a fastener connected to the connecting groove 603 is arranged on the top of the second storage pressure bag 601, and a regulating valve 2 and a check valve connected to the second storage pressure bag 601 are arranged at the bottom of the second connecting hose 604. The second connecting hose 604 is connected to the second storage pressure bag 601 through the regulating valve 2, the check valve and the material connecting pipe 602. The bottom of the second storage pressure bag 601 is connected to the discharge port pipeline. As the obliquely inserted fertilizer rack 6 continues to penetrate into the soil, the second storage pressure bag 601 gradually approaches the soil surface until it is squeezed, and the fertilizer solution inside is squeezed into the second injection port 605;

[0049] A lifting hydraulic cylinder 401 is arranged on the inner wall of the guide limit column 4, and a lifting slider 402 connected to the extension beam 403 is arranged between the lifting hydraulic cylinders 401, an auxiliary wheel 404 is arranged at the bottom of one end of the extension beam 403, side grooves 406 are arranged on the surfaces of both sides of the extension beam 403, a central groove 405 is arranged through the top of the extension beam 403, and multiple groups of servo motors 407 are arranged on the bottom wall of the extension beam 403;

[0050] A connecting hose 604 is provided on the top of the obliquely inserted fertilizing rack 6, a material injection port 605 is provided on the bottom of the obliquely inserted fertilizing rack 6, a tooth groove 606 is provided on the outer walls on both sides of the obliquely inserted fertilizing rack 6, a connecting groove 603 is provided in a depression on the end surface of the obliquely inserted fertilizing rack 6, and a material storage pressure bag 601 is clamped with the connecting groove 603, and a material receiving pipe 602 is provided on the top inclined surface of the material storage pressure bag 601.

[0051] In combination with Example 1, Example 2 and Example 3, it can be known that the shallow soil fertilization treatment of the beans in the seedling state is carried out in a unified and quick manner by breaking the soil and pulling trenches through the shallow soil fertilization rack 5, which helps rainwater and artificial watering to penetrate deep into the trenches, allowing the bean seedlings to fully absorb fertilizer and keep the soil for planting the beans loose, so that the soil at the edge of the rhizomes of the bean seedlings can gather water in the trenches, which helps to ensure the growth needs of the bean seedlings in the early stage of planting. The position deviation of the oblique fertilizer rack 6 and the shallow fertilizer rack 5 during synchronous operation is utilized to form a double-row synchronous fertilization action process, which can not only pierce and fertilize the soil in the rhizome area of ​​the grass plants, but also cooperate with the shallow fertilizer rack 5 to form a coordinated fertilization treatment for intercropping of beans in the same row.
