Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural planting, and more specifically, to a uniform seeding device for agricultural planting. Background Technique
[0002] A seeding device is a planting machine that uses crop seeds as the seeding object.

[0027] Please refer to Figure 1-6 , the present utility model provides a technical solution:
[0028] A uniform seeding device for agricultural planting, including an upper shell 1, a middle shell 2, a lower shell 3 and a cover plate 4. The middle shell 2 is located between the upper shell 1 and the lower shell 3. The two ends of the middle shell 2 are respectively communicated with the bottom of the upper shell 1 and the top of the lower shell 3. The cover plate 4 is located at the top of the upper shell 1 and is fixedly installed. A filter plate 5 is arranged inside the upper shell 1, and filter holes 6 are opened inside the filter plate 5. An output motor 7 is fixedly installed on the top of the cover plate 4, and a uniform discharging structure 8 is arranged inside the upper shell 1.
[0029] Specifically, the uniform discharging structure 8 includes an output rod 81, a rotating block 82, a cleaning rod 83, a scraping rod 84, a connecting rod 85 and a spiral blade 86. One end of the output rod 81 is fixedly connected to the rotating block 82. The inside of the rotating block 82 is rotationally connected to the top of the filter plate 5 through a rotating shaft. One end of the cleaning rod 83 is fixedly connected to the side surface of the rotating block 82. One end of the scraping rod 84 is fixedly connected to the top of the cleaning rod 83. One end of the connecting rod 85 is fixedly connected to the bottom of the rotating block 82. The spiral blade 86 is sleeved on the surface of the connecting rod 85 and is fixedly connected to achieve uniform discharging of seeds.
[0030] Furthermore, the number of cleaning rods 83 and scraping rods 84 is four, and the four cleaning rods 83 and scraping rods 84 are distributed in a circular array at the four corners of the surface of the rotating block 82. The cleaning rods 83 can stir the seeds on the filter plate 5 to prevent the seeds from being too crowded and blocking the water filtering holes 6. The scraping rods 84 can clean the seeds adsorbed on the surface of the middle shell 2 to avoid material leakage.
[0031] It should be noted that the bottom end of the cleaning rod 83 is in a sharp shape, and the side surface of the scraping rod 84 is processed into an arc, and the arc directions of the four scraping rods 84 are the same. The sharp surface can facilitate the extrusion and movement of the seeds. When moving, the seeds will be squeezed into the inside by the cleaning rod 83 when encountering the filtering holes 6. The scraping rod 84 can drive the seeds to move. As the seeds move downward along the arc surface until they move onto the filter plate 5 and then are cleaned into the filtering holes 6 by the cleaning rod 83.
[0032] It is worth noting that a connecting bar 9 is fixedly connected to the output end of the output motor 7. The connecting bar 9 is in the shape of a cuboid. A rectangular groove adapted thereto is provided inside the output rod 81. The connecting bar 9 realizes the connection between the output motor 7 and the uniform seeding structure. The output motor 7 drives the uniform seeding structure to operate through the connecting sleeve during the operation process.
[0033] In addition, the bottom end of the connecting rod 85 and the spiral blade 86 are located inside the lower shell 3. The outer side of the spiral blade 86 is in contact with the inner wall of the lower shell 3. The middle shell 2 is oval. When the seeds are located in the middle shell 2, they will accumulate at the connection between the middle shell 2 and the lower shell 3, and then are evenly fed into the seeding device through the spiral blade 86.
[0034] It has to be said that the cover plate 4 is fixedly installed on the upper shell 1 through bolts and nuts. A handle 10 is fixedly connected to the top of the cover plate 4. The user can drive the cover plate 4 to move through the handle 10.
[0035] Working principle: The user pours seeds into the upper shell 1, then covers the cover plate 4 so that the connecting bar 9 is inserted into the rectangular groove inside, and then fixes the cover plate 4 through bolts and nuts. Then start the output motor 7. The output end of the output motor 7 drives the connecting bar 9 to rotate. The connecting bar 9 drives the output rod 81 to rotate. The rotation of the output rod 81 drives the rotating block 82 to rotate. The rotation of the rotating block 82 drives the cleaning rod 83 and the connecting rod 85 to rotate. The rotation of the cleaning rod 83 drives the scraping rod 84 to rotate. Since the output end of the output motor 7 rotates counterclockwise, the cleaning rod 83 and the scraping rod 84 separate the seeds from the filtering holes 6 through their characteristics. At the same time, the rotation of the connecting rod 85 drives the spiral blade 86 to rotate. The spiral blade 86 rotates in a cycle inside the lower shell 3. After the seeds are separated from the filtering holes 6, they fall to the connection between the middle shell 2 and the lower shell 3, and then the spiral blade 86 evenly drops the seeds from the lower shell 3 into the seeding device to complete the operation. After seeding is completed, the user opens the cover plate 4, then takes out the filter plate 5 for cleaning, and then places it back in place to complete the operation.
[0036] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
