Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to an agricultural scraper. Background Art

[0002] Agricultural machinery scraper blades are important components used for land leveling and are widely used in operations such as field preparation and soil scraping. They typically consist of a blade, a scraper bracket, and other components. The blade, the scraper blade's primary working component, is typically made of wear-resistant materials such as manganese steel to increase its service life and operating efficiency. The scraper bracket secures the blade and withstands various forces during operation. Agricultural machinery scraper blades are widely used in operations such as field preparation, soil scraping, and land leveling. They can be used in conjunction with agricultural machinery such as four-wheel tractors to achieve mechanized operations and improve efficiency and quality. However, current scraper blades are rectangular, fixed, and difficult to adjust. They also occupy a large amount of space when not in use. Therefore, the inventors have proposed an agricultural scraper blade to meet these high demands. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This specific embodiment is an agricultural scraper, and its structural diagram is as follows Figure 1 、 Figure 2 As shown, it includes a scraper body 1, a sub-plate 2 and a connecting frame 3. The sub-plate 2 is movably arranged on both sides of the scraper body 1, and the connecting frame 3 is fixedly installed above the scraper body 1. A connecting mechanism 4 is provided at the connection between the scraper body 1 and the sub-plate 2.

[0024] Reference Figure 3 The connecting mechanism 4 includes a first connecting block 5 and a second connecting block 6. The first connecting block 5 is rotatably mounted above the sub-plate 2, and the second connecting block 6 is rotatably mounted above the scraper body 1. The scraper body 1 and the sub-plate 2 are provided with mounting grooves 9 on their facing surfaces. Support shafts 12 are vertically mounted inside the mounting grooves 9. Connecting rods 9 are sleeved between the support shafts 12. The connecting rods 9 are movably connected to the support shafts 12. Mounting holes 8 are provided on the upper surfaces of the sub-plate 2 and the scraper body 1. Connecting shafts 10 are provided at the corresponding locations of the mounting holes 8 of the first connecting block 5 and the second connecting block 6. The connecting shafts 10 are rotatably connected to the mounting holes 8. A socket is provided on the outer wall of the first connecting block 5. A clamping block 7 is movably provided on the outer wall of the second connecting block 6. The clamping block 7 slides toward the inside of the second connecting block 6, and the clamping block 7 is plugged into the socket.

[0025] Reference Figure 4 The second connecting block 6 has a groove 14 formed inside it, and a spring 15 is installed inside this groove 14. The spring 15 is arranged horizontally, with one end fixedly connected to the inner wall of the groove 14 and the other end fixedly connected to the operating block 13. The operating block 13 vertically penetrates the groove 14 and slides horizontally along the groove 14. The operating block 13 is fixedly connected to the end of the clamping block 7 that penetrates the second connecting block 6. First, pull the operating block 13, and the operating block 13 moves along the groove 14, compressing the spring 15. The operating block 13 drives the clamping block 7 to slide toward the interior of the second connecting block 6.

[0026] Working Principle: When in use, first connect the connecting frame 3 to the tractor, and the scraper body 1 is in contact with the ground. The soil is scraped flat by the blade at the bottom of the scraper body 1. The two sides of the scraper body 1 are rotatably mounted with sub-plates 2. When in use, the sub-plates 2 need to be unfolded. When not in use, the sub-plates 2 can be folded up, thereby reducing the volume of the entire scraper board and making it easy to carry and store.

[0027] The deployment operation of the auxiliary plate 2 and the scraper body 1 is as follows: first, pull the operating block 13, the operating block 13 moves along the groove 14, compresses the spring 15, and the operating block 13 drives the card block 7 to slide toward the inside of the second connecting block 6, and the card block 7 leaves the socket on the first connecting block 5, thereby releasing the limit between the first connecting block 5 and the second connecting block 6, and then the auxiliary plate 2 and the scraper body 1 can be ranged with the fixed shaft and the connecting rod 9 as the support points. After keeping them flush, the first connecting block 5 and the second connecting block 6 can be rotated. Figure 2 As shown, the block 7 on the first connecting block 5 is rotated and adjusted to correspond to the socket on the second connecting block 6 again, and the operating block 13 is pushed by the return elastic force of the spring 15. The block 7 is forced to be inserted toward the inside of the socket, and then the sub-plate 2 is fixed to the scraper body 1 after unfolding, completing the unfolding operation.

[0028] Finally, it should be noted that the above is only 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 can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
