[0024] Please refer to the following: Figures 1 to 5This invention provides a specific embodiment of a sowing device for a multi-vegetable seedbed. The sowing device includes a seed hopper 1 positioned above the seedbed, a seed storage trough 11 on the seed hopper 1, and an adjusting slide 12 connected to the bottom of the seed storage trough 11. The adjusting slide 12 is horizontally positioned, and an adjusting plate 2 is slidably installed within it. The adjusting plate 2 has several seed-leaking holes 21 of different diameters. A seed conveying trough 13 is connected to the bottom of the adjusting slide 12, and the seed conveying trough 13 is connected to the seed storage trough 11 through the seed-leaking holes 21. A seed-distributing roller 3 is rotatably installed within the seed conveying trough 13, and several seed-holding troughs 31 are equidistantly spaced around its circumference. A drive shaft 4 is fixedly connected to the seed-distributing roller 3. One end of the drive shaft 4 is rotatably connected to the seed hopper 1, and the other end passes through the seed hopper 1 and is connected to a driver 5, which drives the seed-distributing roller 3 to rotate.

[0025] In this embodiment, support frames 6 are symmetrically fixedly installed on both sides of the seed hopper 1, and a guide rail 7 is slidably connected to the bottom of each support frame 6. The seedbed is located between the two guide rails 7. The bottom of the seed delivery trough 13 is connected to the seed outlet 14.

[0026] For ease of explanation, please refer to Figure 1 A rectangular coordinate system is established with any point in space as the origin, the setting direction of the guide rail 7 relative to the support frame 6 as the Z-axis, the setting direction of the support frame 6 relative to the seed bucket 1 as the X-axis, and the straight line direction that is perpendicular to both the X-axis and the Z-axis as the Y-axis. The XY plane is a horizontal plane, the direction indicated on the horizontal plane is the horizontal direction, and the direction indicated by the Z-axis is the vertical direction.

[0027] In one specific embodiment of this utility model, the support frame 6 is a rectangular frame structure; the bottom of the support frame 6 is a T-shaped structure, and the guide rail 7 is provided with a T-shaped guide groove 71 that is adapted to the bottom of the support frame 6. The cross-section of the seed storage trough 11 is a trapezoid with a larger top and a smaller bottom, and the cross-section of the seed conveying trough 13 is circular; the two sides of the seed hopper 1 are symmetrically provided with handles 9 for pushing the seed hopper 1 to move.

[0028] In this embodiment, the seed leakage holes 21 on the adjusting plate 2 are arranged in several groups along the Y-axis direction. Each group includes several seed leakage holes 21 spaced apart along the X-axis. The diameter of the seed leakage holes 21 in each group is the same, and the diameter of the seed leakage holes 21 between adjacent groups is different. The seed holding groove 31 is arranged in several groups equidistantly on the outer surface of the seed dividing roller 3. Each group includes several seed holding grooves 31 spaced apart along the X-axis. The center of any seed holding groove 31 is on the same vertical line as the center of the corresponding seed leakage hole 21.

[0029] In one specific embodiment of this utility model, a drive rack 22 is provided on one side of the adjusting plate 2 in the horizontal direction. A drive gear 81 is meshed on the drive rack 22, and a rotating shaft 82 is fixedly connected to the drive gear 81. One end of the rotating shaft 82 is rotatably connected to the seed hopper 1, and the other end passes through the seed hopper 1 and is connected to a turntable 83. A limit rod 84 is slidably connected through the turntable 83. A plurality of limit holes 15 are provided on the surface of the seed hopper 1 opposite to the turntable 83 along the circumference of the rotating shaft 82. The limit rod 84 engages with the corresponding limit hole 15.

[0030] In this embodiment, the seed hopper 1 is provided with a drive groove 16 that is vertically connected to the adjusting slide 12, and the drive gear 81 is installed in the drive groove 16; the outer surface of the turntable 83 is provided with several circumferential graduations. The driver 5 is a handle or a motor fixed to the seed hopper 1. Here, anything that can achieve the above-mentioned performance functions of the driver 5 and the seed hopper 1 is within the scope of protection of this application.

[0031] Compared with existing technologies, this multi-vegetable seedbed sowing equipment, through the setting of several seed-exit holes 21 of different sizes on the adjusting plate 2, can better adapt to the size of different vegetable seeds, achieving a multi-purpose effect. Furthermore, the adjusting plate 2 with corresponding seed-exit holes 21 can be replaced according to the required vegetable spacing, making the replacement process simple and convenient. The seed hopper 1 can be easily moved using the handle 9, support frame 6, and guide rail 7, allowing for continuous sowing operations. The coordinated arrangement of the seed-distributing roller 3, drive shaft 4, and driver 5 allows for intermittent sowing of the seedbed according to the required sowing spacing, avoiding the problem of excessively close sowing spacing affecting seedling quality. This equipment solves the problem of existing technologies being unable to perform intermittent sowing operations according to the sowing spacing, thus affecting the breeding effect.

[0032] The working process of the sowing equipment for various vegetable seedling beds of this utility model is as follows: Select a suitable adjusting plate 2 and insert it into the adjusting groove 12. Observe the position of the seed leakage hole 21 from the top of the seed hopper 1, aligning the required seed leakage hole 21 with the seed storage trough 11. Rotate the turntable 83 to a certain angle. The turntable 83 drives the drive gear 81 to rotate via the rotating shaft 82. The drive gear 81 drives the drive rack 22 to move horizontally, so that the seed storage trough 11 is disconnected from the seed delivery trough 13. At this time, pour the seeds into the seed storage trough 11. Push the handle 9... The seed hopper 1 moves along the guide chute 71 to the sowing pit dug in the seedbed, and rotates the turntable 83 in the opposite direction to a certain angle so that the corresponding seed leakage hole 21 connects the seed hopper 1 with the seed holding trough 31. The limiting rod 84 is inserted into the corresponding limiting hole 15 for fixation. The driver 5 is started to drive the drive shaft 4 to rotate, and at the same time the seed distributing roller 3 rotates, rotating the seed holding trough 31, which carries the seeds at the top, to connect with the seed outlet 14, and the seeds fall into the corresponding sowing pit. After the seed hopper 1 is moved to the next position, the sowing operation continues.

[0033] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
