Description

Technical Field

[0001] The utility model relates to the field of seedling raising and sowing machines, in particular to a soil scraping and regulating device of the seedling raising and sowing machines. Background Art

[0002] The seedling planter is an important piece of agricultural machinery that significantly improves the efficiency and quality of crop sowing. The planter primarily uses a furrow opener to create a furrow in the soil. The seeds in the seed box are then discharged by the seed meter and precisely dropped into the furrow through the seed tube. A coverer then covers the soil, while a compactor compacts it to ensure a suitable growth environment for the seeds. Depending on the sowing method, planters can be categorized into broadcast, row, hole, precision, and combined types to meet the sowing needs of different crops. With the advancement of agricultural mechanization, planters are playing an increasingly important role in agricultural production, and their efficient and precise sowing capabilities have been welcomed by farmers.

[0003] A scraper is provided inside the seedling raising and sowing machine. After soil is spread on the seedling tray, the scraper can scrape the soil on the seedling tray flat. Different types of seedling trays have different heights, and the scraper is fixed inside the seedling raising and sowing machine. The position of the scraper cannot be adjusted according to the height of the seedling tray, resulting in the soil on some seedling trays cannot be completely scraped flat. Therefore, a soil scraping adjustment device for a seedling raising and sowing machine is proposed. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 As shown, a scraping adjustment device of a seeding and sowing machine includes a positioning base 3, an equipment housing 2 is fixedly installed on the positioning base 3, an upper hopper 1 is fixedly installed on the upper end of the equipment housing 2, a conveying roller 5 is movably installed in the equipment housing 2, and an adjusting notch 4 is opened on both sides of the equipment housing 2. A scraping mechanism 6 is installed inside the equipment housing 2, and the scraping mechanism 6 includes a slide seat 601 fixedly installed on the inner wall of the equipment housing 2, and a scraping plate 605 is movably installed in the slide seat 601. A first support leg 603 is fixedly installed on the scraping plate 605, and a second support leg 607 is fixedly installed on the slide seat 601. A compression spring 606 is provided between the first support leg 603 and the second support leg 607. An adjusting mechanism 7 is provided on the equipment housing 2, and the adjusting leg 706 can be driven to move up and down by rotating the adjusting knob 704. When the adjusting leg 706 moves up and down, the scraping plate 605 will be driven to move up and down, thereby adjusting the position of the scraping plate 605 according to the height of the seedling tray.

[0023] like Figure 2 Figure 3As shown, a scraping mechanism 6 is installed inside the equipment housing 2, and the scraping mechanism 6 includes a slide seat 601 fixedly installed on the inner wall of the equipment housing 2, and a scraping plate 605 is movably installed in the slide seat 601. A first support leg 603 is fixedly installed on the scraping plate 605, and a second support leg 607 is fixedly installed on the slide seat 601. A compression spring 606 is provided between the first support leg 603 and the second support leg 607. The scraping mechanism 6 also includes movable notches 604 opened on both sides of the slide seat 601, and a positioning guide rod 602 is fixedly installed on the second support leg 607.

[0024] Specifically, the compression spring 606 will apply elastic force to the first leg 603, causing the first leg 603 to tend to move downward. When the first leg 603 moves, it will drive the scraper plate 605 to move downward, causing the lower end of the scraper plate 605 to contact the upper end of the seedling tray. When the conveying roller 5 drives the seedling tray to pass under the scraper plate 605, the scraper plate 605 will scrape the soil on the seedling tray flat.

[0025] like Figure 3 Figure 4 As shown, the adjustment mechanism 7 includes an adjustment screw 702 fixed on the upper surface of the device housing 2, an adjustment knob 704 is threadedly installed on the adjustment screw 702, an adjustment frame 701 is movably installed on the adjustment screw 702, and adjustment legs 706 are fixedly installed at both ends of the adjustment frame 701. The adjustment mechanism 7 also includes a docking base 705 fixedly installed at the lower end of the adjustment screw 702, a positioning through hole 707 is opened at the edge of the docking base 705, and a fixing nut 703 is connected to the adjustment screw 702.

[0026] Specifically, the user can turn the adjustment knob 704 up and down. After turning the adjustment knob 704 up and down, it will drive the adjustment frame 701 to move up and down. After the adjustment frame 701 moves up and down, it will drive the adjustment support foot 706 to move up and down. When the adjustment support foot 706 moves up and down, it will drive the scraper plate 605 to move up and down. When the scraper plate 605 moves up and down, the user can observe whether the lower end of the scraper plate 605 is in conflict with the upper end of the seedling tray through the adjustment notch 4, and thus adjust the position of the scraper plate 605 according to the height of the seedling tray to scrape the soil on the seedling trays of different heights.

[0027] It should be noted that the present invention is a soil scraping and regulating device for a seedling raising and sowing machine. In actual use, the conveying roller 5 is first used to convey the seedling tray with seeds to the bottom of the upper hopper 1. After the seedling tray is conveyed to the bottom of the upper hopper 1, the soil in the upper hopper 1 can be released so that the soil is spread on the seedling tray. After the soil is spread on the seedling tray, the seedling tray can continue to be conveyed forward. The compression spring 606 will apply elastic force to the first support leg 603, so that the first support leg 603 has a tendency to move downward. When the first support leg 603 moves, it will drive the scraper plate 605 to move downward, so that the lower end of the scraper plate 605 contacts the upper end of the seedling tray. When the seedling tray continues to be conveyed forward, the seedling tray will pass through the scraper plate 605. When the seedling tray passes through the scraper plate 605, the scraper plate 605 will scrape the soil on the seedling tray The user can adjust the position of the scraper 605 according to the height of the seedling tray, so as to make the soil on the seedling tray of different heights be scraped flat.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
