Description

Technical Field

[0001] This utility model belongs to the field of agricultural technology, and specifically relates to a corn seed metering device. Background Technology

[0002] Corn is one of the three major grain crops in my country, accounting for more than 50% of the planting area. Corn planting requires processes such as turning the soil, fertilizing, ridging, and compacting. With the development of agricultural mechanization, wheat and corn are generally sown mechanically. Fertilizer planters are widely welcomed by farmers because they reduce the labor intensity of farmers, improve the germination rate of seeds, and reduce the occurrence of pests and diseases.

[0003] Existing corn planting devices typically include a grooving mechanism, a soil-raising mechanism, a seed-metering mechanism, and a soil-closing mechanism on the frame. The grooving mechanism creates furrows in the soil, the soil-raising mechanism applies fertilizer to these furrows, and then the seed-metering mechanism plants the corn seeds into them. After the fertilizer and seeds are applied, the soil-closing mechanism covers the furrows with soil, ensuring the fertilizer and seeds are covered. A pressure roller then presses down on the covered furrows to prevent them from being exposed. Currently, the soil-closing mechanism mainly uses a soil-closing cutter. Once installed, the position of the soil-closing cutter is not adjustable, and its height is fixed, generally resulting in a fixed thickness of soil covering. This can easily lead to overly thick or thin soil covering when encountering uneven soil surfaces. On the other hand, the soil compaction cutter is installed on the frame via a shock-absorbing rod. Although this can reduce the vibration caused by the soil compaction cutter to the frame, the soil compaction cutter is fixed relative to the frame and does not rotate. It passively pushes the soil by relying on the traction of the frame. Straw and other debris in the soil will get stuck on the soil compaction cutter, causing increased resistance.

[0019] See Figure 1 and Figure 2A corn seeding device includes a frame 1, on which a fertilization mechanism 2, a seeding mechanism 3, and a moisture-combining mechanism 4 are mounted. The moisture-combining mechanism 4 includes a moisture-combining blade 41, a mounting component 42, an elastic component 43, and a rotating component 44. The moisture-combining blade 41 is arranged in an inverted V-shape and is rotatably connected to the mounting component 42. The mounting component 42 is connected to the elastic component 43, which is connected to the frame 1. The mounting component 42 is rotatably connected to the rotating component 44, which is connected to the frame 1.

[0020] In the corn seed metering device, the frame 1, the fertilization mechanism 2, the seed metering mechanism 3, and the soil moisture-retaining mechanism 4 are all existing technologies. The frame 1 has two grooving mechanisms 5, which create two rows of furrows in the soil. Behind each grooving mechanism 5 is a fertilization mechanism 2, which applies waste material to the two rows of furrows. Behind the fertilization mechanism 2 are two seed metering mechanisms 3, which dispense seeds into the two rows of furrows. Behind each of the two seed metering mechanisms 3 is a soil moisture-retaining mechanism 4. This invention mainly improves the soil moisture-retaining mechanism 4 in the corn seed metering device by making the soil moisture-retaining blade 41 height-adjustable to adapt to soil surfaces that are not perfectly level during agricultural operations. Simultaneously, the soil moisture-retaining blade 41 is made self-rotating, and the rotating blade can cut up hard soil clumps and straw, preventing debris from accumulating and clogging the blade.

[0021] In a specific implementation scheme, the soil-covering blade 41 is arranged in an inverted V-shape with a non-contact bottom. The inverted V-shape of the blade 41 allows for soil covering, and it is rotatably connected to the mounting assembly 42. The blade 41 itself can rotate, and by rotating the soil, it can chop up hard soil clumps and straw, preventing debris from clogging the blade. The cutting force generated by the rotation also reduces frictional resistance with the soil. Furthermore, the rotating blade 41 loosens the soil during the soil-covering process, breaking up potential compaction layers and further improving soil aeration.

[0022] After the soil compaction cutter 41 is rotatably connected to the mounting assembly 42, the mounting assembly 42 is connected to the frame 1 through the elastic component 43. The elastic component 43 applies downward pressure to the mounting assembly 42, which indirectly applies downward pressure to the soil compaction cutter 41. This allows the elastic component 43 to give the soil compaction cutter 41 a certain degree of adjustability and adaptability. When encountering raised or depressed soil surfaces, the elastic component 43 will expand and contract with the terrain, causing the soil compaction cutter 41 to adjust its height slightly, but always maintaining the pressure applied to the soil compaction cutter 41, so that the soil compaction cutter 41 maintains effective contact with the soil and avoids local soil covering that is too thick or too thin.

[0023] Specifically, for uneven field surfaces, when the soil compaction tool 41 moves from a relatively flat soil surface to a relatively higher raised area, the elastic component 43 compresses the tool from the raised area and applies downward pressure. This causes the tool to adapt to the raised surface, preventing it from being pushed up by the soil while maintaining its level with the surface, thus reducing excessive soil cover. When encountering depressions, the elastic component 43 continuously applies downward pressure, ensuring the tool remains in contact with the soil and reducing the likelihood of insufficient soil cover.

[0024] In this invention, due to the inclusion of the elastic component 43, the mounting component 42 for mounting the moisture-retaining blade 41 must both support the moisture-retaining blade 41 and accommodate the newly added elastic component 43. Therefore, the mounting component 42 is configured to rotate relative to the rotating component 44. The rotating component 44 supports the mounting component 42 and allows the mounting component 42 to have a certain positional offset capability when subjected to force. Specifically, when the moisture-retaining blade 41 is compressed by a higher protruding surface, the mounting component 42 is subjected to force and can deflect upwards.

[0025] See Figure 2 and Figure 3 In a specific implementation, the mounting component 42 includes a first base 421 and a second base 422. The clamping blade 41 is connected to the first base 421. The second base 422 is provided with a connecting hole for connecting the rotating component 44. The elastic component 43 is connected to the top of the first base 421 and the second base 422.

[0026] A drive motor 423 is connected to the first base 421, and a connecting shaft 424 is connected to the drive motor 423. The moisture-retaining blade 41 is connected to the connecting shaft 424, and a fixing ring is provided on the connecting shaft 424. The fixing ring is located on both sides of the moisture-retaining blade 41 and is used to fix the moisture-retaining blade 41 so that the moisture-retaining blade 41 is stably connected to the connecting shaft 424.

[0027] The first base 421 is used to mount the drive motor 423, providing stable support for the drive motor 423. The control circuit for the drive motor can employ conventional motor control circuits in the art, capable of controlling the start / stop, speed regulation, and forward / reverse rotation of the drive motor.

[0028] The drive motor is used to rotate the connecting shaft 424, which can drive the moisture-retaining blade 41 to rotate, thus enabling the moisture-retaining blade 41 to rotate on its own. The retaining ring is used to fix the moisture-retaining blade 41 to the connecting shaft 424. The moisture-retaining blade 41 is arranged in an inverted V-shape and then connected to the connecting shaft 424. The bottoms of the two moisture-retaining blades 41 arranged in an inverted V-shape are set to a non-contact form to avoid the moisture-retaining blades 41 contacting each other and causing wear when they rotate.

[0029] See Figure 2 and Figure 3 In a specific implementation, the elastic component 43 includes a first spring 431, a second spring 432, and a support frame 433. The bottoms of the first spring 431 and the second spring 432 are respectively connected to connecting plates 434, and the tops of the first spring 431 and the second spring 432 are respectively connected to connecting blocks 435. The connecting blocks 435 are connected to the support frame 433.

[0030] See Figure 2 and Figure 3 In a specific implementation, the support frame 433 includes a first connecting column 4331, a second connecting column 4332, and a connecting beam 4333. The first connecting column 4331 and the second connecting column 4332 are respectively connected to the connecting beam 4333, and the connecting beam 4333 is connected to the frame 1 through a connecting seat 4334.

[0031] The bottom of the first spring 431 is connected to the top of the first base 421 via a connecting plate 434, and the top of the first spring 431 is connected to the first connecting post 4331 via a connecting block 435. The bottom of the second spring 432 is connected to the top of the second base 422 via a connecting plate 434, and the top of the second spring 432 is connected to the second connecting post 4332 via a connecting block 435.

[0032] See Figure 2 and Figure 4 In a specific implementation, the rotating assembly 44 includes a fixed shaft 441, a support rod 442, and a fixed seat 443. The fixed shaft 441 is connected to the support rod 442, the support rod 442 is connected to the fixed seat 443, and the fixed seat 443 is connected to the frame 1.

[0033] The fixed shaft 441 is connected to the connecting hole on the second base 422, and the second base 422 is connected to the fixed shaft 441 by a fixing ring, so that the second base 422 can rotate relative to the fixed shaft 441.

[0034] In a specific implementation, the moisture-retaining mechanism further includes a pressure roller located at the rear end of the moisture-retaining cutter and connected to the frame. The moisture-retaining mechanism is used to cover and bury the fertilizer and seeds in the trench, while the pressure roller, located behind the mechanism, presses down on the buried trench to prevent it from being exposed. It should be noted that the pressure roller is prior art and will not be described further here.
