[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-4This utility model provides an embodiment of a vegetable seed fixed-distance sowing device, including a frame 1, a sowing mechanism 4 installed inside the middle of the frame 1, and a punching mechanism 5 located at the left end of the frame 1. The top right end of the frame 1 is fixedly connected to the bottom of a pusher frame 2. The bottom of the front and rear ends of the frame 1 are provided with movable wheels 3, which increase the ease of movement of the frame 1. The punching mechanism 5 includes a punching wheel 51, with punching heads evenly distributed at equal intervals on its outer side. The punching wheel 51 can punch holes on the soil ridges of the vegetable field. Holes are formed with equal spacing between them. The front and rear rotating rods of the perforating wheel 51 are connected to the interior of the left side wall of the connecting frame 53. An angle sensor 57 is mounted on the front left wall of the connecting frame 53, capable of detecting the rotation angle of the perforating wheel 51. The output end of the angle sensor 57 is connected to the front rotating rod of the perforating wheel 51. The right end of the connecting frame 53 is fixedly connected to the left end of the lifting block 54, which is installed inside the left end of the frame 1. The sowing mechanism 4 includes a feeding frame 41, the interior of which is used to hold vegetable seeds. The bottom of the feeding frame 41 is connected to the top of the through hole of the control frame 42. An electric push rod 43 is mounted on the right end of the control frame 42. The output end of the electric push rod 43 is fixedly connected to the right end of the translation rod 44. A control head 46 is mounted on the left end of the translation rod 44. The control head 46 is located in the through hole of the control frame 42. The bottom of the control frame 42 is connected to the top of the discharge pipe 47. The control head 46 has a conical shape with an arc-shaped tip. The electric push rod 43 can drive the translation rod 44 and the control head 46 to move left and right. When head 46 moves to the right, the vegetable seeds inside the feeding frame 41 will fall out through the through hole of the control frame 42. The electric push rod 43 drives the translation rod 44 and the control head 46 to move to the left, and the through hole of the control frame 42 will close, so the seeds will not fall out. The perforating wheel 51 will make a hole in the soil ridge every time it rotates a certain angle. The angle sensor 57 detects the rotation angle of the perforating wheel 51 to control the feeding of vegetable seeds. In this way, the vegetable seeds can be sown at a fixed distance according to the position of the perforating wheel, which improves the convenience of using the sowing device.

[0021] A spring 45 is mounted on the outside of the translation rod 44. The left end of the spring 45 is fixedly connected to the right end of the control head 46. The spring 45 can increase the stability of the movement of the control head 46.

[0022] The top left end of the frame 1 is vertically connected to the bottom of the fixed frame 6. The fixed frame 6 has an adjusting bolt 7 inside. A bearing is installed at the connection between the adjusting bolt 7 and the fixed frame 6. The adjusting bolt 7 rotates on the fixed frame 6 through the bearing. The rotation of the adjusting bolt 7 will drive the lifting block 54 to rise and fall. The height of the soil ridges in the vegetable field is different. By adjusting the height of the lifting block 54, the height of the punching wheel 51 can be changed, thereby adapting to soil ridges of different heights. The adjusting bolt 7 and the threaded hole of the lifting block 54 are connected by threads. The lifting block 54 has a limiting strip 55 on the front and rear sides. The side of the limiting strip 55 is slidably connected to the side wall of the limiting groove on the left end of the frame 1. The limiting strip 55 can prevent the position of the lifting block 54 from shifting when it rises and falls. The top front and rear sides of the top of the lifting block 54 are equipped with a limiting top plate 56. The limiting top plate 56 is a cuboid structure. The limiting top plate 56 limits the lifting height of the lifting block 54.

[0023] When in use, the adjustment bolt 7 of this device rotates, which drives the lifting block 54 to rise and fall. The height of the soil ridges in the vegetable field varies. By adjusting the height of the lifting block 54, the height of the punching wheel 51 can be changed to adapt to soil ridges of different heights. The electric push rod 43 drives the translation rod 44 and the material control head 46 to move to the right. The vegetable seeds inside the feeding frame 41 will fall out through the through hole of the material control frame 42. The electric push rod 43 drives the translation rod 44 and the material control head 46 to move to the left. The through hole of the material control frame 42 will close, and the seeds will not fall out. The punching wheel 51 punches a hole in the soil ridge every time it rotates a certain angle. The angle sensor 57 detects the rotation angle of the punching wheel 51 to control the feeding of vegetable seeds. In this way, the vegetable seeds can be sown at a fixed distance according to the position of the punching wheel 51, which improves the convenience of using the sowing device.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
