Description

Technical Field

[0001] This utility model relates to the field of seeders, and in particular to an adaptive deep and shallow seeder for corn planting. Background Technology

[0002] To achieve high yield and quality in maize, innovation and improvement in planting techniques are crucial. Sowing, as the initial key step in maize planting, directly affects seed germination rate, seedling growth, and final yield. Appropriate sowing depth provides a suitable soil environment for the seeds, ensuring sufficient water and oxygen supply, which is beneficial for seed germination and root development. Therefore, it is necessary to design an adaptive depth seeder for maize planting.

[0003] Current pesticide spraying methods typically rely on manual experience to assess pest and disease occurrence after corn germination before spraying. This often leads to missed opportunities for optimal control, resulting in uncontrolled pests and diseases, which damages the health of later corn plants and reduces yield. Furthermore, most seeders are equipped with simple, fixed-force covering rollers that cannot be flexibly adjusted, leading to poor covering effect, affecting sowing quality, and lowering corn survival rates. Installing an adjustable covering roller thrust mechanism inside the seeder's covering roller frame would create the optimal soil environment for seed germination, thereby improving germination rates and seedling survival rates.

[0014] (III) Beneficial Effects

[0015] This utility model provides an adaptive depth seeder for corn planting, which has the following beneficial effects:

[0016] 1. This adaptive depth-shallow seeder for corn planting, through its spraying mechanism, first fills the storage tank with pesticide solution before use. A water pump is installed inside the storage tank, drawing the solution out and transmitting it through a water pipe. This solution is then transferred to a storage pipe inside the rolling frame. The storage pipe then evenly sprays the solution from a pressurized nozzle at the bottom, covering the corn seedlings and applying the solution. This increases the survival rate of the corn seedlings, allowing for simultaneous spraying of pesticides and improving survival rates. It avoids the need for later spraying, which increases planting steps and can damage corn seedlings, leading to reduced yield.

[0017] 2. This adaptive depth-shallow seeder for corn planting, through the setting of the adjustment mechanism, in order to better cover the corn seeds with soil when the device is to be used, has a rotatable frame A installed in the middle of the soil rolling frame. The rotating frame A is connected to an adjusting hydraulic rod. The length of the adjusting hydraulic rod is extended and retracted, causing the top adapter block B and the rotating frame B to rotate and stretch, adjusting the force and depth of the soil covering wheel in contact with the ground. This plays a role in adjusting the soil covering wheel to increase the covering force, avoiding the inability to make flexible adjustments, which would lead to poor soil covering effect, affect the sowing quality, and reduce the survival rate of corn.
