[0002] In current agricultural production, sowing and seedling raising is a crucial link in the crop growth cycle. Traditional sowing methods mostly use manual or simple mechanical devices to randomly scatter crop seeds in pre-dug soil sowing troughs. This sowing method has many drawbacks, seriously affecting the growth quality and yield of crops. First, the randomly scattered seeds are unevenly distributed, resulting in too high seed density in some areas, causing intense nutrient competition and affecting the growth of seedlings, while in other areas, the seeds are scarce, the land utilization rate is low, and resources are wasted; second, due to the uneven distribution of seeds, the distribution of natural resources such as light and water during the crop growth process is also uneven, further exacerbating the inconsistency of crop growth. Content of the Utility Model

Detailed implementation manners
[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model claimed, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.
[0022] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, terms such as "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.
[0023] Such as Figures 1 to 3As shown in the figure, a seeding and seedling raising device with good uniformity includes a frame 1. A sinking prevention wheel set 2 is arranged on the frame 1. A grooving structure 3 and a soil filling structure 4 are respectively fixed at the front end and the rear end of the frame 1. A feeding box 5 is fixed above the frame 1. Among them, the sinking prevention wheel set 2 is connected with a rotating roller 6 which is arranged on the frame 1 and can rotate following the sinking prevention wheel set 2. The rotating roller 6 is connected with a gear transmission group which is arranged under the feeding box 5. The gear transmission group is engaged with a reciprocating motion structure 7. The reciprocating motion structure 7 includes a connecting part 71 which can reciprocate up and down. The connecting part 71 is connected with a seeding structure 8 which is connected to the feeding box 5. The seeding structure 8 includes a seeding pipe body 81. Two vertically extending sliding grooves 82 are symmetrically arranged on the outer side of the seeding pipe body 81. A sliding head 83 is clamped in the sliding groove 82. Both sliding heads 83 are connected with the connecting part 71. A conical opening and closing part 84 is arranged at the bottom of the seeding pipe body 81. The opening and closing part 84 is composed of two arc-shaped sectors 841 which are hinged at the bottom of the seeding pipe body 81. The outer side surface of the arc-shaped sector 841 is connected with a traction part 85. The top of the traction part 85 is connected with the sliding head 83.
[0024] In this embodiment, it should be noted that the entire seeding and seedling raising device with good uniformity is directly placed into the cultivation soil for use. Seeding is achieved by moving the entire device. When moving, the grooving structure 3 penetrates into the ground to dig a seedling raising groove. At the same time, the sinking prevention wheel set 2 starts to rotate, thereby driving the rotating rod to rotate. The rotating rod drives the reciprocating motion structure 7 to move through the gear transmission group. After the reciprocating motion structure 7 moves, the connecting part 71 performs reciprocating motion up and down, then drives the sliding head 83 to move along the sliding groove 82, then drives the traction part 85 connected to the sliding head 83 to move up and down as well, and then drives the arc-shaped sector 841 hinged to the seeding pipe body 81 to rotate, completing the alternating reciprocating opening and closing of the opening and closing part 84 continuously. In this way, the crop seeds in the feeding box 5 fall out intermittently. In summary, by controlling the rotation angle of the sinking prevention wheel set 2, the crop seeds will fall out naturally. Through the above, the falling out of crop seeds is automatically controlled by the moving distance of the sinking prevention wheel set 2, achieving uniform distribution of seeds. Compared with the traditional random sowing method, this device can ensure that the number of seeds in each seeding groove path is basically the same, avoiding the problems of too high or too low seed density, thereby improving the land utilization rate and reducing resource waste. Further, the uniform seed distribution enables the crops to obtain natural resources such as light and water more evenly during the growth process, reducing the growth inconsistency problems caused by uneven resource distribution. This is beneficial to the healthy growth of crops and improves the growth quality and yield of crops. Further, through the design of the sliding head 83, the traction part 85 and the arc-shaped sector 841 in the seeding structure 8, the alternating reciprocating motion of the opening and closing part 84 is realized, controlling the intermittent falling out of seeds, with simple operation and easy maintenance and adjustment.

Specifically, the gear transmission group drives the intermediate gear 75 to rotate, the transmission rod 73 rotates accordingly, then the rotating disk 74 rotates following the transmission rod 73, and the limit bolt 76 rotates following the rotating disk 74, so as to realize the reciprocating change in height. Under the action of the activity through groove 791, the limit bolt 76 can drive the connecting rod body 79, the rotating sleeve 78, and the sector body 710 to rotate reciprocally around the rotating pair 77 together.
