Description
Technical Field
[0001] The utility model relates to the field of seed drills, in particular to a soil covering device for wheat seed drills. Background Art
[0002] A wheat seeder is a mechanical device that plants wheat seeds in the soil through a sowing mechanism. It is primarily driven by a tractor and equipped with a fertilizer spreader, enabling efficient wheat sowing and fertilization. Adjusting the seeder's parameters, such as seeding rate and sowing depth, allows for precise sowing and even distribution of wheat seeds, facilitating their subsequent growth and management. The wheat seeder can simultaneously complete multiple processes, including furrowing, sowing, covering, and pressing, significantly improving sowing efficiency and reducing labor costs. Suitable for wheat cultivation in both plains and hilly areas, the wheat seeder has broad adaptability.
[0003] During sowing, the furrow opener in front of the wheat seeder first opens a furrow on the ground, and then the wheat seeds fall into the opened furrow along the conveying pipe to realize automatic sowing. After sowing is completed, the soil covering scraper at the rear of the wheat seeder will push the soil on both sides of the furrow into the furrow to automatically cover the soil. However, there may be some stones on the ground, and the soil covering scraper will be blocked by the stones when moving forward, causing the soil covering scraper to be deformed under force. Therefore, a soil covering device for a wheat seeder is proposed. Utility Model Content

[0022] like Figure 2 and Figure 3 As shown, the covering mechanism 5 includes a positioning frame 502 connected to the frame 1, and the positioning frame 502 is provided with a movable hole 503 and a movable notch 504, a movable shaft 505 is movably installed in the movable hole 503, a scraper arm 507 is fixedly installed on the movable shaft 505, a covering scraper 508 is fixedly installed on the scraper arm 507, a torsion spring 506 is sleeved on the movable shaft 505, a docking port 501 is provided on the positioning frame 502, the positioning frame 502 is mounted on the frame 1 through the docking port 501, a mounting hole is provided on the scraper arm 507, and the movable shaft 505 is mounted on the scraper arm 507 through the mounting hole.
[0023] Specifically, when the soil-covering scraper 508 encounters a stone obstruction, the movable shaft 505 will twist, causing the soil-covering scraper 508 to rotate backward to prevent the soil-covering scraper 508 from being deformed by force. After the stone is cleared, the torsion spring 506 will drive the movable shaft 505 to twist and reset. After the movable shaft 505 is twisted and reset, it will drive the soil-covering scraper 508 on the scraper arm 507 to twist and reset, so that the soil-covering scraper 508 can work again.
[0024] like Figure 2 and Figure 4 As shown, the alarm mechanism 6 includes an alarm 602 fixedly installed in the positioning frame 502 and a fixed bracket 605, fixing screw holes 606 are provided at both ends of the fixed bracket 605, and a release switch 604 is fixedly installed in the middle position of the fixed bracket 605, and the release switch 604 is connected to the power cord 603, and the release switch 604 and the alarm 602 are connected in series through the power cord 603, a positioning base 601 is provided on the alarm 602, and the alarm 602 is installed on the positioning frame 502 through the positioning base 601, and an installation opening is provided in the middle position of the fixed bracket 605, and the release switch 604 is installed on the fixed bracket 605 through the installation opening.
[0025] Specifically, when the covering scraper 508 encounters a stone obstruction, the movable shaft 505 will twist, causing the covering scraper 508 to rotate backward, thereby driving the scraper arm 507 to rotate. After the scraper arm 507 rotates, it will release the release switch 604, thereby turning on the power of the alarm 602. After the power of the alarm 602 is turned on, it will sound an alarm to remind the user that there is a stone in front of the covering scraper 508 and it needs to be handled.
[0026] Working principle: When in use, the entire device is pulled forward. When the entire device moves forward, the wheat seeds in the wheat seed storage box 2 will fall along the wheat seed conveying pipe 3 to complete the sowing of the wheat seeds. After the sowing of the wheat seeds is completed, the soil covering scraper 508 will move forward, thereby pushing the soil on both sides of the groove into the groove, covering the wheat seeds in the groove. The soil covering scraper 508 may encounter stone obstructions when moving forward. When the soil covering scraper 508 encounters stone obstructions, the movable shaft 505 will twist, causing the soil covering scraper 508 to rotate backward to prevent the soil covering scraper 508 from being deformed by force, and when the soil covering scraper 508 rotates backward, it will drive the scraper arm 507 to rotate. Since the release switch 604 is installed on one side of the scraper arm 507 through the fixed bracket 605, and the scraper arm 507 is pressed against the release switch 604, the scraper arm 507 rotates. After that, it will release the release switch 604. After releasing the release switch 604, the power of the alarm 602 can be turned on. After the power of the alarm 602 is turned on, it will sound an alarm to remind the user that there are stones in front of the soil scraper 508 and it needs to be cleaned. Since the movable shaft 505 is movably installed on the positioning frame 502 through the movable hole 503, the scraper arm 507 is movably installed on the positioning frame 502 through the movable shaft 505, one end of the torsion spring 506 is fixed on the movable shaft 505, and the other end of the torsion spring 506 is fixed on the positioning frame 502. Therefore, after the cleaning is completed, the torsion spring 506 will drive the movable shaft 505 to twist and reset. After the movable shaft 505 is twisted and reset, it will drive the soil scraper 508 on the scraper arm 507 to twist and reset, so that the soil scraper 508 can work again.
[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
