[0002] With the development of modern agricultural technology, corn seeding equipment, as a key tool for achieving mechanized and precise planting, has become increasingly important.

[0003] In some small-scale planting situations, large agricultural machinery and equipment are often difficult to access or not an economically reasonable option due to the small plots, complex terrain, or cost considerations. Therefore, farmers and growers prefer to use smaller, more flexible seeding equipment to access these fields and perform precise, fixed-point seeding operations. However, many conventional small seeding equipment on the market do not fully consider the adjustability of planting spacing in their designs. As a result, in actual operations, it is difficult for growers to flexibly adjust the spacing during seeding according to crop growth needs, soil conditions, and planting plans, thus affecting the growth distribution, light utilization, and final yield of corn crops.

[0021] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0022] Example

[0023] A corn sowing device described in this embodiment, such as Figures 1 to 3 As shown, the roller 1 comprises a solid wheel with only a central hole formed at its center during production. A central shaft 14 is independently mounted within the central hole of the roller 1. To reduce friction, a bearing can be installed between the central shaft 14 and the central hole. A bracket 13 is secured to the rear end of the central shaft 14, extending through the central hole. A screw 2 is secured to the front end of the bracket to prevent the roller 1 from falling off. A threaded hole is formed at the center of the front end of the central shaft 14. The stud of the screw 2 threadably engages the threaded hole. The nut of the screw 2 is larger than the central hole of the roller 1, preventing the roller 1 from falling off the central shaft 14. Of course, if a bearing is installed between the central shaft 14 and the central hole, the nut of the screw 2 can prevent dirt from entering the bearing.

[0024] like Figure 2 As shown, a push rod 5 for pushing the roller 1 to move is fixed on the bracket 13. The bracket 13 is an "L"-shaped structure, and the connecting end of the push rod 5 is fixed on the bracket 13 and is in the same vertical plane as the roller 1.

[0025] like Figure 5 As shown, a mounting sleeve 4 is fixed to the push rod 5. The mounting sleeve 4 is rectangular in structure and has a circular hole inside. The rectangular mounting sleeve 4 increases the fixing area and facilitates fixing to the push rod 5. To facilitate fixing to the mounting sleeve 4, the cross-section of the left half of the push rod 5 is set to a rectangular structure, and the right half is circular.

[0026] like Figure 2 As shown, a handle ring 6 is fixed to the movable end of the push rod 5. The handle ring 6 has an isosceles trapezoidal structure. Since this structure only has one roller 1, it needs to remain stable during movement. Therefore, the isosceles trapezoidal structure of the handle ring 6 is conducive to maintaining the stability of the roller 1. In addition, two support legs inclined to the sides can be fixed to the push rod 5. When not in motion, the support legs support the push rod 5 to prevent it from falling.

[0027] A hopper 3 is fixed on the outer wall of the mounting sleeve 4, and a feed port communicating with the inside and outside is opened on the side wall of the mounting sleeve 4 corresponding to the lower bucket mouth of the hopper 3; the hopper 3 is a narrow bottom and wide top structure, and the lower bucket mouth of the hopper 3 is fixed on the outer wall of the mounting sleeve 4, and the feed port is communicated with it.

[0028] Below the corresponding feed port, a discharge port is provided on the side wall of the mounting sleeve 4, communicating with the inside and outside. A feed pipe 9, communicating with the discharge port, is fixed to the outer wall of the mounting sleeve 4. The feed port is located above the discharge port, with the two sides aligned with each other. A valve stem 10 is independently installed in the mounting sleeve 4. The valve stem 10 has a through hole connecting the feed port and the discharge port, located in the middle of the valve stem 10. When the through hole is connected to the feed port and the discharge port, the corn in the hopper 3 leaks out of the feed pipe 9 and is sown in the field.

[0029] like Figure 1 and Figure 5 As shown, a spring 8 is installed within the mounting sleeve 4 at the right end of the corresponding valve stem 10. One end of spring 8 is connected to the right end of valve stem 10, and the other end is connected to a fixing plate 7, which is fixed to the right end of mounting sleeve 4. When spring 8 is in its natural position, the through-hole and the feed port intersect. This section as a whole constitutes a thrust assembly for pushing valve stem 10 leftward and intersecting the through-hole and the feed pipe. During use, the thrust of spring 8 causes valve stem 10 to slide leftward, intersecting the through-hole and the feed port, and the right half of valve stem 10 blocks the feed port, preventing the corn in mounting sleeve 4 from falling.

[0030] The two ends of the spring 8 are connected to the fixed plate 7 and the spring 8 respectively. When the spring 8 is in a natural state, the through hole is just staggered with the feed port, so as to avoid the valve stem 10 sliding to the left, which may cause the structure to fail to complete its function.

[0031] In addition, the spring 8 can be mounted on the valve stem 10 so that one end of the spring rests on the left end of the mounting sleeve 4 and the other end rests on the guide head 12, which can also make the valve stem 10 slide to the left.

[0032] A guide head 12 is fixed to the movable end of the valve stem 10, and a number of connecting holes are opened on the front side wall of the roller 1, and all the connecting holes are evenly spaced along the circumference of the roller 1; a detachable guide wheel 11 is connected to any one or more connecting holes, and a guide groove is opened on the rear side wall of the guide head 12; the guide wheel 11 passes through the guide groove to make the valve stem 10 slide to the right and the through hole is connected to the feed port.

[0033] like Figure 6 As shown, the guide wheel 11 includes a wheel core 11.2, on which a wheel sleeve 11.1 is independently mounted, and a limiting hook groove is provided on the wheel core 11.2 to limit the shedding of the wheel sleeve 11.1; a connecting rod 11.3 is fixed at the center of the wheel core 11.2, and an external thread is provided on the outer wall of the connecting rod 11.3, and an internal thread is provided on the inner wall of the connecting hole to threadably match the external thread.

[0034] like Figure 4As shown, the right wall of the guide groove is inclined, with the left side higher and the right side lower. The right wall of the guide groove is located on the moving path of the guide wheel 11. During use, as the roller 1 rotates, the guide wheel 11 passes through the guide groove and contacts the right side wall of the guide groove. Due to this inclined surface, the guide head 12 can only move left and right. When the guide wheel 11 contacts the inclined surface, the guide head 12 moves to the right, pushing the valve stem 10 to the right, connecting the through hole with the feed port. The corn falls through the through hole, passes through the discharge port, and is guided by the feed pipe 9, so that the corn seeds are sown in the farmland, completing a sowing cycle.

[0035] After the guide wheel 11 passes through the guide groove, the valve stem 10 slides to the left under the push of the spring 8, and the feed port is closed by the valve stem 10, prohibiting discharge of materials.

[0036] The wheel sleeve 11.1 and the wheel core 11.2 cooperate to reduce the friction between the guide wheel 11 and the guide groove. The connecting rod 11.3 is connected to the connecting hole by a thread. When three of the connecting holes are equipped with guide wheels 11, and these three guide wheels are evenly spaced, the roller 1 will complete three sowing operations for each rotation of the roller 1.

[0037] During production, scale lines can be set on the front side wall of the roller 1 to express the angle between the connecting holes, so as to facilitate the installation of two adjacent guide wheels 11 at equal intervals.

[0038] In actual use, the frequency of the movement of the valve stem 10 is controlled by adjusting the angle at which two adjacent guide wheels 11 are installed on the roller 1, thereby adjusting the sowing spacing.
