Description

Technical Field

[0001] The invention relates to the technical field of fertilization equipment, and in particular to a corn planting positioning fertilization equipment. Background Art

[0002] Corn contains various nutrients such as glutathione, lutein and zeaxanthin, magnesium and selenium, glutamate, dietary fiber, calcium, phosphorus, etc.

[0003] With the development of society, corn has been planted on a large scale, and the planting process requires fertilizing the corn according to the production cycle of the corn plants. For example, the invention patent with announcement number CN116138016A discloses a four-row corn intertillage fertilization vehicle, which includes two double-row fertilization assemblies located on both sides of the three-wheel fertilization vehicle. The double-row fertilization assembly includes a rolling bracket and two disc-type hole-piercing fertilization mechanisms. The rolling bracket includes a U-shaped main bracket and two U-shaped axle brackets. A fertilizer box is installed on the U-shaped main bracket. The two U-shaped axle brackets are symmetrically installed at the lower ends of two support rods on both sides of the U-shaped main bracket. The fixed-plant hole-piercing fertilization method is beneficial to reducing the loss of water in the soil and improving the fertilizer utilization rate.

[0004] However, when the fertilizer application vehicle in the above application applies fertilizer to corn, the disc-type hole-piercing fertilizer application mechanism moves in the middle of the corn row, and the applied fertilizer is far away from the roots of the corn plants, which is not convenient for targeted fertilization of the corn roots according to corn planting. As a result, the applied fertilizer is not conducive to the absorption of the corn plants, resulting in poor fertilization effect.

[0037] In the present invention, a control box for opening and closing the electrical components on the fertilizing member 5 is also installed on the base plate 1. The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field. The present invention is mainly used to protect mechanical structures, so the present invention will no longer elaborate on technical means such as control methods and circuit connections.

[0038] In an optional embodiment, the fertilizer application member 5 includes a telescopic plate 51 fixedly connected to the base plate 1, the telescopic end of the telescopic plate 51 is fixedly connected to a connecting plate 517, a hydraulic rod 516 is fixedly installed on the base plate 1, and the output end of the hydraulic rod 516 is fixedly connected to the connecting plate 517, the telescopic end of the telescopic plate 51 is fixedly connected to a material guide bin 52, one side of the material guide bin 52 is rotatably connected to a support rod 53, the outer side of the support rod 53 is fixedly connected to a group of cross bars 55, one side of the telescopic plate 51 is fixedly connected to a support column 514, the end of the support column 514 is plugged with a support frame 513, and the sliding connection on the cross bar 55 At least one sliding ring 56 is connected, and at least one supporting ring 58 is slidably connected to the outer side of the supporting frame 513, and a supporting block 510 is fixedly connected to the outer side of the supporting ring 58.

[0039] In this embodiment, when the support column 514 conflicts with the support frame 513, the activated hydraulic rod 516 drives the telescopic plate 51 to contract, which can drive the guide rod 59 to move downward. After the telescopic rod 511 that extends following the guide rod 59 is extended and can no longer be extended, the conical block 512 extending to the root of the corn can be pulled and rotated by the telescopic rod 511, thereby propping up the soil at the root of the corn, so that the fertilizer transported to the guide rod 59 can be applied to the soil through the guide rod 59, so as to position the fertilization of the corn roots, improve the absorption effect of the corn fertilizer, and thus improve the fertilization effect.

[0040] It should be noted that a fixed ring 518 is fixedly connected to the outer side of the upper end of the guide rod 59, and a movable ring 520 is slidably connected to the outer side of the upper end of the guide rod 59. A return spring 519 is fixedly connected between the fixed ring 518 and the movable ring 520. The upper surface of the movable ring 520 is fixedly connected to a limit block 512 whose end extends to the inside of the cross bar 55. The limit block 512 extending into the cross bar 55 is used to limit the sliding ring 56 from sliding on the cross bar 55. Conversely, the limit block 512 is pulled to separate from the cross bar 55, so that the sliding ring 56 and the support ring 58 can be swung laterally to slide.

[0041] Among them, the telescopic plate 51 is composed of a sleeve plate and a slide plate. The sleeve plate is fixedly connected to the bottom plate 1, and the slide plate is slidably connected to the inner side of the sleeve plate. The end of the slide plate located on the outer side of the sleeve plate is L-shaped. The connecting plate 517 is fixedly connected to the slide plate.

After the convex end of the support frame 513 and the concave end of the support column 514 are fitted together, the support ring 58 and the support block 510 on the support frame 513 can rigidly support the guide rod 59.

[0043] Secondly, a number of limit grooves 522 are opened on one side of the cross bar 55 close to the movable ring 520. The limit grooves 522 are evenly distributed on the cross bar 55, and the specifications of the limit grooves 522 are compatible with the specifications of the limit blocks 521. The sliding ring 56 is supported and limited by the limit blocks 521 extending into the limit grooves 522.

[0044] Then, the end of the cross bar 55 away from the support rod 53 and the end of the support frame 513 are both T-shaped, and the ends of the cross bar 55 and the support frame 513 are threadedly connected with circular blocks. By tightening the circular blocks at the ends of the cross bar 55 and the support frame 513, a T-shape is formed. By unscrewing the circular blocks, the sliding sliding ring 56 and the support ring 58 can be slid out to increase or decrease, and the number and orientation of the sliding ring 56 and the support ring 58 of the cross bar 55 are adapted.

[0045] Finally, the telescopic rod 511 is composed of a sleeve rod and a sliding rod. The sleeve rod is hinged on the support block 510, and the sliding rod is slidably connected to the inner side of the sleeve rod. The end of the sliding rod located on the outer side of the sleeve rod is hinged to the conical block 512, and the end of the sliding rod located on the inner side of the sleeve rod is T-shaped, so that the sliding rod can slide inside the sleeve rod. When the T-end of the sliding rod collides with the opening of the sleeve rod, the sliding rod can no longer slide outward on the sleeve rod.

[0046] In an optional embodiment, a spray piece for spraying fertilizer on corn is provided on the inner side of the material guide bin 52; the spray piece includes two extension frames 57 which are slidably connected to the inner side of the material guide bin 52, a plurality of first nozzles 524 are connected to the lower surface of the material guide bin 52, a plurality of second nozzles 525 are connected to the lower surface of the extension frame 57, a double-axis cylinder 523 is installed on one end of the telescopic plate 51 connected to the material guide bin 52, and a connecting rod 526 with one end fixedly connected to the extension frame 57 is fixedly connected to the output end of the double-axis cylinder 523.

Sealing rings are embedded in the sealing groove and the opening of the material guide bin 52. The opening of the extension frame 57 is located on the inner side of the material guide bin 52. When the second nozzle 525 is in the sealing groove, the second nozzle 525 can be sealed, and the second nozzle 525 exposed from the sealing groove can cooperate with the first nozzle 524 to widen the fertilizer spraying range.

[0049] In an optional embodiment, a conveying member 4 for conveying fertilizer to the guide bin 52 and the guide rod 59 respectively is provided on the storage bin 2, and the conveying member 4 includes a pump body 41 fixedly installed on the storage bin 2, and the output end of the pump body 41 is connected to a conveying pipe 42 whose one end is connected to the guide bin 52, and the end of the conveying pipe 42 connected to the guide bin 52 is connected to a connecting pipe 43 whose one end is connected to the middle guide pipe 515.

[0051] It should be noted that the delivery pipe 42, the connecting pipe 43 and the material guide pipe 515 are all hoses, and the connection between the delivery pipe 42, the connecting pipe 43 and the material guide bin 52 and the connection between the connecting pipe 43 and the middle material guide pipe 515 are all connected through a three-way valve.

[0052] The working principle in the above embodiment is:

[0053] By controlling the three-way valves on the guide bin 52 and the middle guide pipe 515, the fertilizer delivered by the pump body 41 is delivered to the middle guide pipe 515, and then flows into the plurality of guide rods 59 in sequence through the plurality of guide pipes 515, the hydraulic rod 516 can be activated to lower the telescopic plate 51 to drive the guide bin 52, the support rod 53, the cross bar 55 and the support frame 513, and the downwardly moved cross bar 55 can drive the guide rod 59 to move downward, and the support ring 58 and the support block on the support frame 513 can move downward. 510 can support the guide rod 59 and pull the telescopic rod 511.
