Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeding machine technology, and in particular to a novel corn planting seeding machine. Background Technology
[0002] The new type of corn planter is an agricultural machinery device that applies modern technology to improve and innovate upon traditional corn planters. It aims to enhance the efficiency, quality, and accuracy of corn planting, better meeting the needs of modern agricultural production. These new planters typically feature high operating speeds and wide operating widths, enabling them to complete large-area planting tasks in a shorter time. Simultaneously, functions such as simultaneous seed and fertilizer application reduce the number of field operations, lowering labor intensity and production costs.
[0003] In the prior art, such as patent CN215529827U, a novel corn planting machine is proposed, including a base plate, a fixed handrail fixedly connected to the front surface of the base plate, and a support column fixedly connected to the top of the base plate. Through the design of a fixed box, a first connecting box, an engine, a drive wheel, a seed storage box, a fixed trough, and a fixed block, the machine operates by using the engine to power the drive wheel. When the device moves, the stability is improved by holding the fixed handrail. During movement, seeds are transferred from the seed transfer tube and fall into the soil through the fixed trough, solving the problem that the device is too large to be suitable for small-scale planting.
[0004] However, some corn seeds require suitable temperature, humidity, and oxygen conditions to germinate. Sowing too deep results in lower soil temperatures and relatively less oxygen, delaying germination and even causing seeds to rot due to lack of oxygen, thus reducing the germination rate. Conversely, sowing too shallow exposes the seeds to the surface, leading to rapid water evaporation and difficulty in maintaining sufficient humidity, which also affects normal germination. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a novel corn planting machine. In areas with compacted soil or high moisture content, the planting plate can be raised to increase the planting depth, allowing seeds to better contact the soil and absorb water and nutrients. Various factors in the field can cause the planter to move, such as wind, collisions with other machinery, or human error. Fixing the planter to the ground prevents accidental movement, avoids damage to already planted areas, and ensures planting effectiveness and the integrity of the field layout.
[0006] To achieve the above objectives, a novel corn planting and seeding machine is provided, comprising a housing, wherein two second racks are fixedly connected inside the housing, and a second gear is meshed inside the second racks. A first drive rod is fixedly connected inside the second gear, and a first motor is fixedly connected to the output end of the first drive rod. A seeding plate is fixedly connected to the outside of the first drive rod, and multiple seed outlets are provided inside the seeding plate.
[0007] According to the novel corn planting machine, the inside of the housing has two first limiting grooves, and a first sliding block is slidably connected inside the first limiting groove.
[0008] According to the novel corn planting machine, the first sliding block is fixedly connected to a feed inlet, and the box body is fixedly connected to two first racks.
[0009] According to the novel corn planting machine, the first gear is internally meshed with the first rack, and the interior of the first gear is fixedly connected to the exterior of the feed inlet.
[0010] According to the novel corn planting machine, a handrail is fixedly connected to the outside of the box, and a water storage tank is fixedly connected to the rear side of the box.
[0011] According to the novel corn planting machine, the water storage tank is externally connected to a port, and one end of the water storage tank is fixedly connected to multiple nozzles.
[0012] According to the novel corn planting machine, two rollers are fixedly connected to the bottom of the housing, multiple threaded rods are threaded inside the housing, and a third gear is threaded outside the threaded rods.
[0013] According to the novel corn planting machine, the third gear is externally meshed with a fourth gear, the fourth gear is internally fixedly connected with a second drive rod, the output end of the second drive rod is fixedly connected with a second motor, and the bottom of the threaded rod is fixedly connected with a chassis.
[0014] Beneficial effects:
[0015] 1. Driven by a first motor and a first drive rod, the external first gear rotates. The first gear moves within the housing under the action of a first rack. As it moves, the seeding plate outside the first drive rod rotates, scattering corn seeds from the seed outlet. The height of the seeding plate, driven by the first motor, can be adjusted to accommodate variations in soil texture, moisture, and compaction in different regions. Adjusting the seeding plate height controls the sowing depth of the corn seeds. In areas with looser soil, the seeding plate height can be lowered to allow for shallower sowing, facilitating seed emergence. In areas with compacted or moist soil, the seeding plate can be raised to increase the sowing depth, allowing for better seed contact and absorption of water and nutrients.
[0016] 2. Driven by the second motor and the second drive rod, the third gear at the bottom rotates, which in turn drives the surrounding fourth gears. These fourth gears, in turn, drive the internal threaded rod, which moves within the housing until it contacts the base plate, thus fixing the device to the ground. This prevents accidental movement of the seeder due to various factors in the field, such as wind, collisions with other machinery, or human error. Fixing the seeder to the ground prevents damage to already sown areas and ensures optimal sowing results and the integrity of the field layout.

[0029] Specifically: Driven by the first motor 13, the first drive rod 12 drives the external first gear 11 to rotate. The first gear 11 moves under the action of the first rack 5 inside the housing 1. When pushed, the seeding plate 8 outside the first drive rod 12 will rotate accordingly.

[0032] Specifically: the first gear 11 moves under the action of the first rack 5 inside the housing 1, and the seeding plate 8 outside the first drive rod 12 will rotate accordingly when pushed.
[0033] The first gear 6 is internally meshed with the first rack 5, and the inside of the first gear 6 is fixedly connected to the outside of the feed inlet 7.
[0034] A handrail 2 is fixedly connected to the outside of the box 1, and a water tank 16 is fixedly connected to the rear side of the box 1.
[0035] Specifically: The operator pushes the handle 2 and moves it using the rollers 14 at the bottom.
[0036] The water storage tank 16 has an external fixed connection to a port 17, and multiple nozzles 18 are fixedly connected to one end of the water storage tank 16.
[0037] Specifically: water is poured into the water storage tank 16 through the port 17 at the rear of the box 1, and the soil attached to the surface of the seeding plate 8 is cleaned by the nozzle 18.
[0038] Two rollers 14 are fixedly connected to the bottom of the housing 1. Multiple threaded rods 19 are threaded inside the housing 1, and a third gear 20 is threaded outside the threaded rods 19.
[0039] Specifically: Driven by the second motor 23, the second drive rod 22 drives the third gear 20 at the bottom to rotate, and the third gear 20 drives the fourth gear 21 around to rotate.
[0040] The third gear 20 is externally meshed with a fourth gear 21, the fourth gear 21 is internally fixedly connected with a second drive rod 22, the output end of the second drive rod 22 is fixedly connected with a second motor 23, and the bottom of the threaded rod 19 is fixedly connected with a chassis 15.
[0041] Specifically: the fourth gear 21 drives the internal threaded rod 19 to rotate, and the threaded rod 19 moves inside the housing 1, so that the bottom plate 15 of the threaded rod 19 contacts and fixes the device to the ground.
[0042] Working principle: Corn seeds are poured into the feed inlet 7. Then, the operator pushes the handle 2 and moves it through the rollers 14 at the bottom. Then, driven by the first motor 13, the first drive rod 12 drives the external first gear 11 to rotate. The first gear 11 moves under the action of the first rack 5 inside the housing 1. When pushing, the seeding plate 8 outside the first drive rod 12 will rotate accordingly, and the corn seeds will be scattered from the seed outlet 9. Since the seeding plate 8 is driven by the first motor 13 to adjust the height, it can accommodate different soil textures, moisture and compaction in different regions. By adjusting the height of the seeding plate 8, the sowing depth of corn seeds can be controlled. In areas with loose soil, the height of the seeding plate 8 can be appropriately lowered to allow the seeds to be sown shallower, which is conducive to seed emergence. In areas with compacted soil or high humidity, the seeding plate 8 can be raised to increase the sowing depth, allowing the seeds to better contact the soil, absorb water and nutrients, and improve the germination rate and seedling survival rate. After sowing, water is poured into the water storage tank 16 through the port 17 at the rear of the box 1. The soil adhering to the surface of the seeding plate 8 is cleaned by the nozzle 18. Then, driven by the second motor 23 and the second drive rod 22, the third gear 20 at the bottom is rotated. The third gear 20 drives the fourth gear 21 around it to rotate, which in turn drives the internal threaded rod 19 to rotate. The threaded rod 19 moves inside the box 1, so that the bottom plate 15 of the threaded rod 19 contacts and fixes the device to the ground. Various factors in the field may cause the seeder to move, such as wind, collisions with other machinery, or human error. Fixing the seeder to the ground can prevent it from moving accidentally, avoid damage to the sown area, and ensure the sowing effect and the integrity of the field layout.
