DETAILED DESCRIPTION
[0026] 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.
[0027] As shown in the figure, a crop seed seeder includes:
[0028] The outer shell 5 is a circular shell-shaped structure with a center line parallel to the horizontal plane, so that the center line of the turntable 6 installed therein can also be parallel to the horizontal plane;
[0029] The turntable 6 is rotatably mounted inside the outer shell 5, and has a plurality of storage cavities 601 evenly arranged in the circumferential direction. The outer surface of the turntable 6 is provided with a ratchet 4 that rotates synchronously with the turntable 6;
[0030] The inner cavity of the feeding pipe 7 is connected with the inner cavity of the turntable 6;
[0031] The unloading drive mechanism includes a pawl 8 that can be raised and lowered vertically. The pawl 8 is arranged on one side of the ratchet 4 and can engage with the ratchet 4. When the pawl 8 rises, it can engage with the ratchet 4, thereby causing the ratchet 4 to rotate at a certain angle, thereby driving the turntable 6 to rotate. When the turntable 6 rotates at a certain angle, the material storage chamber 601 can stay at the lowest limit position in turn, thereby achieving the unloading effect.
[0032] Specifically, it also includes a silo 3, which is arranged at the top of the outer shell 5. When the turntable 6 rotates, the seeds in the silo 3 can fall into the storage cavity 601 in the circumferential direction of the turntable 6 through the lower discharge port. The silo 3 can store more seeds at one time and is easy to carry.
[0033] A handle 1 is fixed on the top of the silo 3, and the handle 1 is mainly used for facilitating the carrying of the video player.
[0034] The unloading drive mechanism also includes a pull rod 9, which is slidably installed in a fixed guide sleeve 10, wherein the guide sleeve 10 is fixedly installed below the handle 1 and is arranged in a vertical direction to guide the up and down movement of the pull rod 9. A reset spring 16 is installed inside the guide sleeve 10. The reset spring 16 can make the pull rod 9 be in the lower extreme position in a natural state, and when the turntable 6 needs to rotate, the pull rod 9 is pulled up.
[0035] Specifically, the pawl 8 is rotatably mounted on the lower end of the pull rod 9 through the first pin 18. One side of the lower end of the pull rod 9 has a limiting surface 901 for limiting the rotation angle of the pawl 8. A torsion spring is sleeved on the first pin 18, which can drive the pawl 8 to move closer to the direction of the ratchet 4 when it is not under force; in the natural state, such as Figure 5 As shown, the right side of the pawl 8 is limited by the limiting surface 901, and the torsion spring also applies a force to the pawl 8, so that Figure 5 In this state, the pawl 8 remains stationary. When the pawl 8 moves upward, it can mesh with the teeth in the circumferential direction of the ratchet 4, driving the ratchet 4 and the turntable 6 to rotate by a fixed angle. When the upward force applied to the pull rod 9 disappears, the pull rod 9 will drive the pawl 8 downward under the action of the return spring 16. During the downward movement, the pawl 8 contacts the ratchet 4, allowing the pawl 8 to swing around its rotation center in the opposite direction of the limit surface 901 and return to the lower limit position. Each time the pawl 8 moves upward, it drives the turntable 6 to rotate by a fixed angle, so that the storage chamber 601 can gradually stay at the lowest point of the turntable 6, facilitating the falling of seeds.
[0036] The unloading drive mechanism also includes a pull wire 11 connected to the pull rod 9, and a control handle 2 for controlling the pull wire 11, wherein the control handle 2 is installed on the handle 1, which can facilitate the operator to pinch the control handle 2, and the operation is convenient; the structural design of the control handle 2 and the pull wire 11, its structure and principle are similar to the handbrake structure on the bicycle in the prior art, and will not be elaborated here.
[0037] A spring plunger 17 is installed at the end surface of the outer shell 5, and a plurality of grooves 602 are provided at the end of the turntable 6, which are concave and match the spring plunger 17. When the turntable 6 rotates, the steel ball at the end of the spring plunger 17 can enter the groove 602, thereby preventing the turntable 6 from shaking easily and improving the rotation accuracy.
[0038] The lower end of the discharge pipe 7 has a spike portion 15, one side of the spike portion 15 is an open structure, and a rotatable opening and closing piece 14 is installed below the discharge pipe 7 through a second pin shaft 13, and a torsion spring is installed on the second pin shaft 13. The opening and closing piece 14 is close to the spike portion 15. The opening and closing piece 14 can be in an open state under the action of the torsion spring, so that the opening of the spike portion 15 is opened. More specifically, a foot pedal 12 extending to the outside of the discharge pipe 7 is fixed to the upper end of the opening and closing piece 14. When the operator steps on the foot pedal 12, the opening and closing piece 14 can be closed to prevent soil from entering the inside of the discharge pipe 7 due to the opening at the bottom during the process of the discharge pipe 7 entering the soil.
[0039] When this crop seed seeder is sowing, the seeds are first introduced into the hopper 3, and then the handle 1 can be held to operate the seeder. After the sowing position is determined, the foot is stepped on the pedal 12, and the pedal 12 drives the opening and closing piece 14 to close the opening of the spike part 15 and insert it into the soil. Then, by squeezing the control handle 2, the pawl 8 is moved up, the ratchet 4 is rotated, and the turntable 6 is driven to rotate. One of the storage cavities 601 with seeds moves to the lower end position of the turntable 6, and the seeds fall into the discharge pipe 7. When the discharge pipe 7 is extracted, the force on the pedal 12 disappears, the opening and closing piece 14 opens under the action of the torsion spring, and the seeds fall into the soil, completing the sowing work. It has the characteristics of convenient operation and accurate feeding.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to 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.
