[0014] The corn planting demonstration device of this utility model has the following advantages compared with the prior art:

[0015] 1. By mounting the container tank on a support frame, the support frame supports the container tank, allowing it to hold white sand. The white sand in the container tank falls onto a conveyor belt, which then moves the white sand. By mounting the seeding mechanism on the support frame, with the container tube located to one side of the seeding mechanism, the support frame supports the seeding mechanism, allowing it to scatter seeds onto the white sand on the conveyor belt. This allows workers to observe the distance of the seeds on the white sand, demonstrating the spacing between the scattered seeds and showcasing the actual working effect of the seeding mechanism. 2. By mounting a vibration mechanism on top of the collection box assembly and connecting it to the filter box, the vibration mechanism drives the filter box to vibrate, sieving the seeds and white sand falling into the filter box. This ensures that the seeds remain in the filter box and the white sand falls into the collection box assembly, improving the user experience.

[0016] 2. By placing the collection box inside the collection tank and positioning it below the filter tank, the white sand flowing out of the filter tank can fall into the collection box, thus enabling the collection box to collect the white sand for reuse by staff.

[0017] 3. By connecting the handle to the collection box and positioning the handle within the opening, the user experience of the product is improved by allowing the collection box to be moved via the handle.

[0018] 4. By mounting four rotating seats on two support plates respectively, connecting the cams to the rotating seats, and making the bottoms of the four cam filter boxes fit together, the support plates support the rotating seats, allowing the cams to rotate within the rotating seats. This allows the rotating cams to drive the filter boxes up and down, causing the filter boxes to vibrate and thus improving the filtration effect of the filter boxes.

[0019] 5. By connecting one end of the guide rod to the support plate and having the other end of the guide rod pass through the bottom of the spring and the rotating seat in sequence, the spring can extend and retract on the outside of the guide rod, thus preventing the spring from bending. At the same time, it also allows the rotating seat to move up and down along the guide rod, thus preventing the rotating seat from shifting during the up and down movement. By connecting the limiting plate to the other end of the guide rod and placing the limiting plate above the bottom of the rotating seat, the limiting plate can limit the rotating seat, thus preventing the rotating seat from moving off the guide rod, thereby improving the user experience of the product.

[0020] 6. By connecting two synchronous pulleys to two cams located on both sides of the collection box body, and simultaneously fitting a synchronous belt around the outside of the two synchronous pulleys, the cams located on both sides of the collection box body are connected together through the two synchronous pulleys and the synchronous belt, thereby enabling the four cams to rotate synchronously and drive the filter box to move up and down synchronously, thus improving the user experience of the product.

[0021] 7. By installing the regulating seat at the bottom of the container, the regulating plate passes through the regulating seat and is positioned below the discharge port, so that the regulating seat can support the regulating plate, thereby enabling the regulating plate to move within the regulating seat and thus partially close the discharge port to regulate the discharge flow rate.

[0029] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0030] A corn planting demonstration device, such as Figures 1 to 5 As shown, the corn planting demonstration device includes a planting mechanism 10. The device comprises: a base plate 11, a support frame 12, transmission rollers 13, a conveyor belt 14, a receiving tank 15, a discharge port 16, a filter box 17, filter holes 18, a collection box assembly 19, and a vibration mechanism 20. The support frame 12 is mounted on the base plate 11, and the planting mechanism 10 is mounted on the top of one end of the support frame 12. Two transmission rollers 13 are respectively embedded in both ends of the support frame 12, and are rotatably connected to the support frame 12. The conveyor belt 14 is simultaneously fitted around the outside of the two transmission rollers 13, and is located within the planting mechanism. Below the seeding mechanism 10; the receiving tank 15 is a hollow cavity with an opening at the top, the receiving tank 15 is mounted on the support frame 12, and the receiving tank 15 is located on one side of the seeding mechanism 10; the discharge port 16 is located at the bottom of the receiving tank 15; the filter box 17 is a hollow cavity with an opening at the top, and the filter box 17 is located below the other end of the support frame 12; the filter hole 18 is located at the bottom of the filter box 17; the collection box assembly 19 is mounted on the base plate 11, and the collection box assembly 19 is located below the filter box 17; the vibration mechanism 20 is mounted on the top of the collection box assembly 19, and the vibration mechanism 20 is connected to the filter box 17.

[0031] By mounting the support frame 12 on the base plate 11, embedding the two drive rollers 13 into the two ends of the support frame 12 respectively, and rotatably connecting the two drive rollers 13 with the support frame 12, the support frame 12 supports the two drive rollers 13, thereby enabling the two drive rollers 13 to rotate within the support frame 12. By simultaneously mounting the conveyor belt 14 on the outside of the two drive rollers 13 and positioning the conveyor belt 14 below the sowing mechanism 10, the two drive rollers 13 cooperate to support the conveyor belt 14, thereby enabling the rotation of the drive rollers 13 to drive the conveyor belt 14 to move, thus allowing the seeds sown by the sowing mechanism 10 to fall onto the conveyor belt 14, and for the conveyor belt 14 to move the seeds. By mounting the container 15 on the support frame 12 and positioning the container 15 on one side of the sowing mechanism 10, the support frame 12 can support the container 15, thereby enabling the container 15 to hold the white sand. By setting the discharge port 16 at the bottom of the container 15, the white sand inside the container 15 can fall onto the conveyor belt 14 through the discharge port 16, thereby enabling the conveyor belt 14 to move the white sand so that the seeds sown by the sowing mechanism 10 can fall onto the white sand. By positioning the filter box 17 below the other end of the support frame 12 and setting multiple filter holes 18 at the bottom of the filter box 17, the white sand and seeds carried by the conveyor belt 14 can be poured into the filter box 17. This allows the white sand to be removed from the filter box 17 through the filter holes 18, thus leaving the seeds inside the filter box 17 for filtration. By mounting the collection box assembly 19 on the base plate 11 and positioning it below the filter box 17, the base plate 11 supports the collection box assembly 19, allowing the white sand flowing out of the filter box 17 to fall into the collection box assembly 19 for collection. By mounting the vibration mechanism 20 on top of the collection box assembly 19 and connecting it to the filter box 17, the vibration mechanism 20 can drive the filter box 17 to vibrate, thereby improving the seed filtration effect.

[0032] In actual use of the product, first pour white sand into the container 15, allowing the white sand in the container 15 to fall onto the conveyor belt 14; then, rotate the drive rollers 13, causing the two drive rollers 13 to work together to move the conveyor belt 14, thereby causing the conveyor belt 14 to move the white sand; as the white sand continuously falls onto the conveyor belt 14, and the conveyor belt 14 moves the white sand, the white sand forms a straight line on the conveyor belt 14; then, start the sowing mechanism 10, causing the sowing mechanism 10 to scatter the seeds onto the white sand; in the sowing mechanism 10 During continuous operation, the staff can observe the distance between the seeds on the white sand, thus demonstrating the spacing between the seeds sown by the seeding mechanism 10. Then, when the conveyor belt 14 moves the seeds and white sand to the other end of the support frame 12, the white sand and seeds will fall into the filter box 17. Then, the vibration mechanism 20 is activated, causing the filter box 17 to vibrate, so that the white sand can flow out through the filter holes 18 and fall into the collection box assembly 19, thereby completing the filtration of the seeds and the collection of the white sand.

[0033] With the above structure, by installing the container 15 on the support frame 12, the support frame 12 supports the container 15, thereby enabling the container 15 to hold white sand and allowing the white sand inside the container 15 to fall onto the conveyor belt 14, which in turn enables the conveyor belt 14 to move the white sand. By installing the sowing mechanism 10 on the support frame 12 and placing the container tube on one side of the sowing mechanism 10, the support frame 12 supports the sowing mechanism 10, enabling the sowing mechanism 10 to scatter seeds onto the white sand on the conveyor belt 14. This allows the operator to observe the distance between the seeds on the white sand, thereby demonstrating the spacing between the seeds sown by the sowing mechanism 10 and allowing the operator to observe the working effect of the sowing mechanism 10. By installing the vibration mechanism 20 on the top of the collection box assembly 19 and connecting the vibration mechanism 20 to the filter box 17, the vibration mechanism 20 can drive the filter box 17 to vibrate, thereby screening the seeds and white sand that fall into the filter box 17, so that the seeds can stay in the filter box 17 and the white sand can fall into the collection box assembly 19, thus improving the user experience of the product.
