DETAILED DESCRIPTION

[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a technical solution for a sowing device: a sowing device, comprising a sowing frame 1, a bearing seat 4 is symmetrically arranged at the front end of the sowing frame 1, a roller 5 is connected between the two bearing seats 4, a sowing roller 23 is mounted on the roller 5, and the outer wall of the sowing roller 23 is circumferentially arranged with soil turning blocks 14 at equal intervals. When the sowing roller 23 rotates, the soil turning blocks 14 can turn over the soil to provide a sowing space for seeds. A fixed sleeve 2 is arranged on the sowing frame 1, and a sowing barrel 15 is installed in the fixed sleeve 2. Seeds are stored in the sowing barrel 15. When the sowing roller 23 rolls to a fixed position, the sowing barrel 15 can drop seeds.

[0022] The rear end of the sowing frame 1 is provided with an inclined rod 16, and a handle 17 is installed on the inclined rod 16, which facilitates the sowing device to be pushed forward by the handle 17. A reinforcement rod 18 is provided between the sowing frames 1, and the reinforcement rod 18 improves the structural strength of the sowing frame 1 to prevent it from deforming during use.

[0023] The seeding barrel 15 is provided with a housing 3, and a delivery assembly is provided in the housing 3, and the delivery assembly includes a micro motor 31, an eccentric disc 32 is connected to the output end of the micro motor 31, a boss 33 is provided on the eccentric disc 32, a connecting block 34 is installed outside the boss 33, a connecting rod 35 is installed on the connecting block 34, a positioning recess 36 is provided at the bottom of the connecting rod 35, a barrel cover 37 is installed in the positioning recess 36, and the barrel cover 37 is tightly attached to the bottom opening of the seeding barrel 15. When the micro motor 31 is working, it drives the eccentric disc 32 to rotate, thereby driving the boss 33 to make a circular motion, and then drives the barrel cover 37 to make an up and down reciprocating motion through the connecting block 34 and the connecting rod 35, so as to realize the opening and closing of the barrel cover 37, thereby controlling the delivery of seeds.

[0024] The connecting block 34 is rotatably connected to the boss 33 and the connecting rod 35, and the cylinder cover 37 is rotatably connected to the positioning recess 36. This connection mode allows the connecting rod 35 and the cylinder cover 37 to rotate freely, thereby successfully completing the delivery action. The tail end of the connecting rod 35 is connected to the cylinder cover 37, ensuring that the movement of the connecting rod 35 can directly drive the movement of the cylinder cover 37. The connecting rod 35 passes through the housing 3 and is slidably connected thereto. This connection mode allows the connecting rod 35 to slide freely in the housing 3, ensuring the normal operation of the delivery assembly.

[0025] The working principle of the utility model is as follows: when in use, the farmer pushes the sowing device forward through the handle 17, the sowing roller 23 rolls under the drive of the roller 5, and the soil turning block 14 turns over the soil to provide a sowing space for the seeds. When the sowing roller 23 rolls to a fixed position, the micro motor 31 starts to work, and drives the cylinder cover 37 to open through the eccentric disk 32, the boss 33, the connecting block 34 and the connecting rod 35, and the seeds in the sowing cylinder 15 are dropped into the soil from the bottom opening to complete the sowing action. When the sowing roller 23 continues to roll, the cylinder cover 37 is closed under the drive of the connecting rod 35 to prevent the seeds from continuing to be dropped. By repeating the above actions continuously, continuous sowing is achieved.

[0026] The utility model has a simple structure and is easy to operate. It can realize the integrated operation of sowing and turning the soil, improve the sowing efficiency, and reduce the labor intensity of farmers. At the same time, the whole device is small in size, easy to carry and store, and is particularly suitable for small farmland or complex terrains such as mountains and hills. The delivery component is driven by a micro motor, with a high degree of automation and high delivery accuracy, which improves the uniformity and consistency of sowing.
