Detailed Embodiment
[0020] In order to deepen the understanding of the utility model, the following will further describe the utility model in detail with reference to the drawings and embodiments. The embodiment is only used to explain the utility model and does not limit the protection scope of the utility model.
[0021] Embodiment:
[0022] The specific implementation process of the utility model: A hill-drop seeder structure of the utility model, as Figures 1-4As shown, it includes a support housing 1, a storage hopper 2, a discharge hopper 4, and a screening housing 5; the screening housing 5 is fixedly connected to the support housing 1, the discharge hopper 4, and the storage hopper 2, and a screening shaft 6 is rotatably provided. Screening grooves 7 are formed on the screening shaft 6, a telescopic column 3 is slidably provided on the housing, a connecting frame 11 is fixedly provided on the telescopic column 3, a transmission block 12 and a telescopic spring 10 are fixedly provided on the connecting frame 11, the transmission block 12 is in transmission connection with the screening shaft 6, and the telescopic spring 10 is fixedly connected to the support housing 1.
[0023] The support housing 1 can be fixedly connected to an external tractor, which is convenient for the external tractor to move together with the structure of the hill-drop seeder of the present invention. The telescopic column 3 can abut against or be fixedly connected to the free end of an external electric push rod, so that the external electric push rod can push the telescopic column 3 to move downward. When sowing, first pour the seeds into the storage hopper 2. The seeds in the storage hopper 2 will enter the screening housing 5 through the outlet at the bottom of the storage hopper 2. Press the telescopic column 3 downward, and the telescopic column 3 will drive the connecting frame 11 and the transmission block 12 to move downward together. The telescopic spring 10 is stretched, and the transmission block 12 pushes the screening shaft 6 to rotate. The seeds in the screening grooves 7 will rotate with the screening shaft 6, pass through the bottom outlet of the screening housing 5 from the upper end of the screening shaft 6, enter the bottom of the discharge hopper 4, and fall onto the soil from the bottom outlet of the discharge hopper 4; when no longer pressing the telescopic column 3 downward, the telescopic spring 10 can drive the connecting frame 11 and the telescopic column 3 to move upward and return to the original position, and the storage hopper 2 is fixedly connected to the support housing 1.
[0024] As Figure 4 shown, a number of convex blocks 14 arranged in a ring are fixedly provided on the screening shaft 6, a groove 13 is formed at the lower end of the transmission block 12, and the convex blocks 14 and the groove 13 are adapted to each other.
[0025] When the transmission block 12 moves downward, the groove 13 will move downward together with the transmission block 12, and the convex block 14 can extend into the groove 13, and the screening shaft 6 can be pushed to rotate through the groove 13 and the convex block 14.
[0026] As Figure 1 、 Figure 2 and Figure 4 shown, a number of tooth blocks are fixedly provided at the upper end of the transmission block 12, a baffle 8 is slidably connected to the support housing 1, a semi-gear portion 15 is fixedly provided at one end of the baffle 8, the other end abuts against the top of the discharge hopper 4, and the semi-gear portion 15 abuts against the tooth blocks.
[0027] When the transmission block 12 moves downward, the tooth blocks will move downward together with the transmission block 12, and the tooth blocks will push the semi-gear portion 15, so that the semi-gear portion 15 drives the baffle 8 to move outward from the support housing 1, and the baffle 8 will push aside the excess soil on the ground to facilitate burying the seeds in the soil.
[0028] As Figure 2 and Figure 5 shown, an installation block 9 is fixedly arranged on the support shell 1. A sliding groove is formed in the installation block 9. A return spring 16 is fixedly arranged in the sliding groove, and a slider 17 is slidably arranged therein. The slider 17 is fixedly connected to the baffle 8 and the return spring 16.
[0029] When the baffle 8 moves towards the outside of the support shell 1, it will drive the slider 17 to move together. The slider 17 will slide in the sliding groove and compress the return spring 16. After the baffle 8 moves towards the outside of the support shell 1, the return spring 16 will push the slider 17 to move, and the slider 17 will drive the baffle 8 to move towards the inside of the support shell 1 together.
[0030] The above embodiments should not limit the present invention in any way. All technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
