Description

Technical Field

[0001] This utility model relates to the field of corn planting technology, and in particular to a corn planting fertilization device. Background Technology

[0002] With the global trend of agriculture transforming towards modernization and intelligence, the concept of precision agriculture is gradually gaining popularity. Precision fertilization, as an important component of precision agriculture, aims to accurately control the amount, time, and location of fertilizer application based on the growth needs of crops, soil fertility, and environmental factors, in order to improve fertilizer utilization and reduce resource waste and environmental pollution. As an important food crop widely grown worldwide, corn exhibits significant stage-specific changes in its demand for various nutrients such as nitrogen, phosphorus, and potassium throughout its growth cycle. However, sufficient phosphorus fertilizer plays a crucial role in this stage, greatly contributing to the healthy development of corn roots.

[0003] However, in actual agricultural production scenarios, traditional manual fertilization is difficult to achieve highly precise positioning. During the fertilization process, it is difficult to accurately deliver fertilizer to the most suitable location around the corn roots. This results in a large deviation in fertilizer placement, causing different corn plants to have varying fertilizer absorption efficiency. Corn plants that fail to effectively absorb enough fertilizer experience slower growth and, compared to other plants that are absorbing fertilizer normally, their growth consistency is severely disrupted, ultimately having a very adverse impact on the overall corn yield. To address this issue, we propose a corn planting fertilization device. Utility Model Content

[0004] The purpose of this invention is to provide a corn planting and fertilization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corn planting and fertilization device, comprising two sets of fixed frames and multiple sets of crossbeams installed between the two sets of fixed frames. Each fixed frame and crossbeam is equipped with a conveying pipe. Each crossbeam has a dispensing nozzle connected to its side end via two sets of connecting hoses. Each of the two sets of fixed frames has a guide groove at its top, and guide sliders are slidably connected within each guide groove. Support frames are installed at the top of each set of guide sliders. A linear actuator is installed at the center of the top of the support frame.

The end of the locking block can be inserted into the slots on the side plate. A pull handle is fixed in the middle of the movable sleeve. A return spring is wound around the outside of both sets of guide slide rods.

[0007] As an improved technical solution, the input terminal of the linear driver is electrically connected to an external controller via a wire.

Movable sleeves 18 are provided on the outside of the two sets of guide slide rods 16. The bottom end of the movable sleeve 18 is connected to a retaining block 20 through the lower connecting plate 19. The end of the retaining block 20 can be inserted into the slot 15 on the side plate 14. A pull handle 21 is fixed in the middle of the movable sleeve 18. A return spring 22 is wound around the outside of the two sets of guide slide rods 16.

[0028] By installing a movable sleeve 18 on the outside of the support frame 8, and cooperating with the side plate 14 fixed on the outside of the conveying pipe 3, the movable sleeve 18 can drive the locking block 20 on the lower connecting plate 19 to quickly insert into the corresponding slot 15 on the side plate 14, so as to effectively position the support frame 8, thereby facilitating the control of the position of the support frame 8 on the fixed frame 1, accurately controlling the opening position of the corn seed opening rod 11 and the fertilizer opening rod 12, and improving the convenience of using the device.

[0029] In other embodiments, the input terminal of the linear driver 9 is electrically connected to an external controller via a wire;

[0030] This design allows an external controller to control the start and stop of the linear drive 9 in real time, ensuring that the linear drive 9 can drive the pressure plate 10 to rise and fall.

[0031] In other embodiments, the guide groove 6 on the fixing frame 1 is provided with an opening at its end;

[0032] This design allows the support frame 8 to move two sets of guide sliders 7 to the opening of the guide groove 6, thus facilitating the quick disassembly of the support frame 8 as a whole.

[0036] This design allows the lower connecting plate 19 to drive the locking block 20 to quickly insert into the slot 15 on the side plate 14, so that the locking block 20 can provide a stable limit for the movement of the support frame 8.

[0037] In other embodiments, the movable sleeve 18 is provided with two sets of sliding holes corresponding to the guide slide rods 16, and the movable sleeve 18 is slidably connected to the two sets of guide slide rods 16 through the two sets of sliding holes;

[0038] This design allows the movable sleeve 18 to move along the surfaces of the two sets of guide rods 16, ensuring the stability of the movable sleeve 18 during movement.

[0039] This utility model provides a corn planting and fertilization device, the specific working principle of which is as follows:

[0040] When using this equipment, the fixed frame 1 and the crossbeam plate 2 can be correctly placed in the planting area. Then, the support frame 8 drives the linear actuator 9 to move to the side of the crossbeam plate 2, allowing the linear actuator 9 to drive the pressure plate 10 to descend. The pressure plate 10 then drives the corn seed hole opening rod 11 and fertilizer hole opening rod 12 at the bottom to insert into the soil, allowing the corn seed hole opening rod 11 and fertilizer hole opening rod 12 to open corresponding corn seed and fertilizer holes on the ground. When it is necessary to move the support frame 8, the handle 21 on the outside of the movable sleeve 18 can be pulled, allowing the movable sleeve 18 to drive the locking block 20 on the lower connecting plate 19 to disengage from the locking groove 15 on the side plate 14. Then, the support frame 8 can be pushed, allowing the support frame 8 to drive the two sets of guide sliders 7 along the guide groove 6 on the fixed frame 1. The displacement is performed. When the support frame 8 moves to the next crossbeam plate 2, the tension on the pull handle 21 can be released, allowing the return springs 22 outside the two sets of guide slide rods 16 to release their elasticity and push the movable sleeve 18 to move along the guide slide rod 16. The lower connecting plate 19 at the bottom of the movable sleeve 18 drives the locking block 20 to insert into the corresponding slot 15 on the side plate 14. Then, the linear driver 9 pushes the pressure plate 10 to work. Subsequently, the dispensing nozzle 5 on the corresponding crossbeam plate 2 can be placed into the prepared fertilizer dispensing hole. When fertilization is required inside the machine, the corresponding fertilizer can be put into the fertilizer box 13. Then, the fertilizer box 13 will transport fertilizer into the delivery pipe 3, and the dispensing nozzle 5 will accurately dispense the corresponding fertilizer into the fertilizer dispensing hole. The operation is then completed.

[0041] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
