Detailed Implementation

[0044] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Specific details are set forth in the following description to provide a full understanding of the invention. However, the invention can be practiced in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0046] Example 1

[0047] like Figure 1 As shown, the modular automatic seed supply device of the present invention includes a seed-carrying mechanism 1, a seed-dropping mechanism 2, a seed-collecting mechanism 3, and a driving mechanism 4. The seed-carrying mechanism 1 is mounted on the seed-dropping mechanism 2, which is located above the seed-collecting mechanism 3. The seed-carrying mechanism 1, the seed-dropping mechanism 2, and the seed-collecting mechanism 3 are fixedly connected by a connector 5. Driven by the driving mechanism 4, the seeds in the seed-carrying mechanism 1 fall into the seed-collecting mechanism 3 through the seed-dropping mechanism 2. In this embodiment, the driving mechanism 4 is connected to the seed-collecting mechanism 3 through the connector 5.

[0048] like Figure 1 As shown in Figure 2(c), the seed-carrying mechanism 1 includes a seed box 11 and a seed-embedding tray 12. The seed box 11 is placed on the seed-embedding tray 12, and the seed box 11 contains crop seeds. (See Figure 2(c) and...) Figure 4 As shown, the seed tray 12 includes a seed box fixing seat 122. In this embodiment, the seed box fixing seat 122 is annular, that is, the seed box fixing seat 122 is a disc with a circular hole in the center. Several seed outlets 124 are spaced apart along the circumference of the seed box fixing seat 12. In this embodiment, the seed outlets 124 are circular. Seed box fixing seats 122 are fixed to the upper surface of the seed box fixing seat 12 and along the circular edge of the opening. The seed box 11 is disposed inside the seed box fixing seat 122. A seed box positioning groove 121 is provided on the seed box fixing seat 122, through which the seed box 11 and the seed box fixing seat 122 are connected. Several seed tray positioning holes 123 are also provided on the circumferential edge of the seed box fixing seat 122. The connecting member 5 passes through the seed tray positioning hole 123, thereby achieving a fixed connection between the seed tray fixing seat 12 and the seed dropping mechanism 2.

[0049] like Figure 3 As shown, the seed box 11 is a hollow frustum shape. The top of the seed box 11 has a seed-throwing port 112, through which crop seeds are placed into the cavity of the seed box 11. The bottom of the seed box 11 is located within a seed box fixing seat 122. A locking protrusion 113 is provided on the lower part of the annular outer side of the seed box 11. When the seed box 11 is placed within the seed box fixing seat 122, the position of the seed box is fixed by the interference fit between the locking protrusion 113 and the seed box fixing seat 122. Simultaneously, a hinge block 111 is also provided on the lower part of the annular outer side of the seed box 11. When the seed box 11 is placed within the seed box fixing seat 122, the hinge block 111 fits precisely within the seed box positioning groove of the seed box fixing seat 122. The hinge block 111 and the seed box fixing seat 122 are hinged together by components such as a rotating shaft. In this embodiment, the seed tray 12 has twelve openings 124, and each opening 124 has a seed box above it. Therefore, there are twelve seed boxes in this embodiment.

[0050] The seed-dropping mechanism 2 includes a seed-dropping tray 21, a seed-dropping tray support plate 22, and a seed-dropping tube 23. The seed-dropping tray support plate 22 is located below the seed-embedded box 12, and the seed-dropping tray 21 is located between the seed-dropping tray support plate 22 and the seed-embedded box 12. The seed-dropping tray is slidably disposed within the seed-dropping tray support plate 22. The seed-dropping tube 23 is located below the seed-dropping tray support plate 22.

[0051] like Figure 6The seed tray support plate 22 is annular, with several support plate positioning holes 221 spaced apart along its circumference. When the connector passes through the support plate positioning holes 221 and the seed tray positioning holes 123, a fixed connection can be achieved between the seed tray support plate 22 and the seed tray 12. A circular hole is provided in the center of the seed tray support plate 22, and a seed tray slide 222 is provided outside the circular hole. The seed tray 21 is located at the center of the seed tray support plate 22 and can rotate along the seed tray slide 222. The seed tray slide 222 limits the rotation direction of the seed tray 21. A notch is provided on one side of the seed tray support plate 22, forming a seed tray exposed area 223. At the seed tray exposed area 223, the seed tray 21 is connected to the drive mechanism 4. During operation, the drive mechanism 4 drives the seed tray 21 to rotate within the seed tray slide 222.

[0052] like Figure 5 As shown, the seed dropping tray 21 is annular in shape, and external teeth 211 are provided on the outer surface of the annular surface of the seed dropping tray. The external teeth 211 are connected to the drive mechanism 4. During the operation of the drive mechanism 4, the seed dropping tray 21 is rotated through the meshing transmission between the drive mechanism and the external teeth 211. The seed dropping tray 21 is provided with a seed inlet 212. The upper surface of the seed dropping tray 21 is located below the lower seed inlet of the seed box. Therefore, the upper surface of the seed dropping tray forms a seed-blocking surface 213. The seed-blocking surface 213 plays a blocking role on the crop seeds in the seed box 11 above it, causing the crop seeds to be blocked and accumulated in the seed box 11 above the seed-blocking surface 213, preventing them from falling.

[0053] When the seed inlet 212 on the seed tray 21 rotates to be directly below a certain seed outlet 124, the seeds in the seed box located at that seed outlet will fall directly from the seed inlet 212 into the seed tube 23 under the action of gravity. At this time, the seeds in the other seed boxes 11 will remain in their respective seed boxes due to the obstruction of the seed-blocking surface 213.

[0054] In this embodiment, a seed dropping tube 23 is provided below the seed dropping tray plate, and a corresponding seed dropping tube 23 is provided below each seed box, so that the crop seeds in each seed box can fall directly into the corresponding seed dropping tube 23 under the action of gravity.

[0055] like Figure 7 As shown, the seed-dropping tube 23 includes a seed-dropping pipe 232, with a seed-dropping port 231 at the top of the seed-dropping pipe 232. The seed-dropping port 231 is located directly below each seed-dropping port inside the seed-embedding box. A seed-dropping tube positioning plate 234 is fixed to the bottom of the seed-dropping pipe 232. The seed-dropping tube positioning plate 234 has a seed-dropping tube positioning hole 233. When the connector is placed in the seed-dropping tube positioning hole 233, a fixed connection between the seed-dropping tube 23 and the seed-collecting mechanism 3 is achieved.

[0056] like Figure 1As shown in Figure 2(a), the drive mechanism 4 includes a stepper motor 42 and a motor base 41. The body of the stepper motor 42 is fixed on the motor base 41. The output shaft of the stepper motor 42 is connected to a drive gear 43. The drive gear 43 passes through the exposed area 233 of the seed dropping tray on the seed dropping tray support plate and meshes with the external teeth 211 of the seed dropping tray set inside the seed dropping tray support plate. During the operation of the stepper motor 42, the drive gear 43 rotates, and through the meshing between the drive gear 43 and the external teeth 211, it drives the seed dropping tray 21 to rotate. During the rotation of the seed dropping tray 21, the seed dropping action of the crop seeds is realized by controlling the rotation speed and rotation frequency of the seed dropping tray 21.

[0057] like Figure 10 As shown, the motor base 41 includes a motor mounting sleeve 411 and a motor seat 413. The motor mounting sleeve 411 is fixedly mounted on the motor seat 413, and the stepper motor 42 is fixed inside the motor mounting sleeve 411. The motor seat 413 is provided with a motor mounting hole 412. When the connector is set in the motor mounting hole 412, the motor seat 413 can be fixed on the seed collecting mechanism 3, thereby realizing the fixed connection between the drive mechanism 4 and the seed collecting mechanism 3.

[0058] The seed collection mechanism 3 includes a seed dropping frame 31 and a seed collection tube 32, with the seed dropping frame 31 located above the seed collection tube 32. For example... Figure 8 As shown, the seed-dropping rack 31 includes a positioning disc 314 and an inoculation wall 313 fixedly connected to the bottom of the positioning disc 314. The top of the inoculation wall 313 is fixedly connected to the positioning disc 314, and the bottom of the inoculation wall 313 is fixedly connected to the top of the seed collection tube 32. In this embodiment, the inoculation wall 313 is a hollow inverted frustum shape. After the crop seeds fall into the seed-dropping rack 31, they will slide down the inclined surface of the inoculation wall 313 under the action of gravity.

[0059] The positioning disc 314 is provided with a fixing hole 311 and a positioning hole 312. When the connecting piece passes through the positioning hole 312 on the positioning disc 314 and the seed tube positioning hole 233 on the seed tube in sequence, a fixed connection between the positioning disc 314 and the seed tube 23 can be achieved. When the connecting piece passes through the positioning hole 312 on the positioning disc, the seed tube positioning hole 233 on the seed tube and the motor fixing hole 412 in sequence, a fixed connection between the drive mechanism 4 and the positioning disc 314 can also be achieved. When the connecting piece passes through the fixing hole 311 on the positioning disc, the tray positioning hole 221 on the seed tray bracket 22 and the seed tray positioning hole 123 on the seed tray 12 in sequence, a fixed connection between the seed carrying mechanism 1, the seed dropping mechanism 2 and the seed collecting mechanism 3 is achieved.

[0060] like Figure 9As shown, the seed collection tube 32 includes an inverted conical seed collection wall 322, with a seed collection port 321 at the top of the seed collection wall 322, which is fixedly connected to the bottom of the inoculation wall 313. The bottom of the seed collection wall 322 is provided with a seed supply port 323, through which crop seeds fall into the soil.

[0061] like Figure 1 As shown, the connector 5 in this embodiment includes a connecting bolt 51 and a seed-dropping tube fixing bolt 52. The upper end of the connecting bolt 51 passes through the seed-insertion tray positioning hole 123 on the seed-insertion tray and the tray positioning hole 221 on the seed-dropping tray support plate, respectively. The lower end of the connecting bolt 51 passes through the positioning hole 312 on the seed-dropping frame, thereby achieving a fixed connection between the seed-insertion tray 12, the seed-dropping tray support plate 22, and the seed-dropping frame 31. The seed-dropping tube fixing bolt 52 sequentially passes through the motor fixing hole 412 on the motor base, the seed-dropping tube positioning hole 233 through the seed-dropping tube, and the fixing hole 311 of the seed-dropping frame, thereby fixing both the motor base 41 and the seed-dropping tube 23 onto the seed-dropping frame 31.

[0062] The seed supply process using this device is as follows. First, crop seeds are inserted into the seed box 11 through the seed-throwing port at the top of the seed box 11. In practical applications, the twelve seed boxes in this embodiment can hold up to twelve varieties of crop seeds, meaning that the varieties of crop seeds in each seed box are different. The varieties of crop seeds are not limited to different varieties of the same crop; they can also be seeds from different crops. Then, the drive mechanism 4 is activated. During the operation of the stepper motor 41, the drive gear 43 is driven to rotate through the output shaft. Through the meshing between the drive gear 43 and the external teeth 211 of the seed dropping disc 21, the seed dropping disc 21 is driven to rotate. When the seed-throwing port 212 on the seed dropping disc 21 rotates to be directly below a certain seed box, the crop seeds in the seed box, under the action of gravity, pass sequentially through the lower seed opening 124 and the seed-throwing port 212, falling into the seed dropping tube 23 directly below. At the same time, the seed-blocking surface 213 on the seed tray acts as a seal against the bottom of other seed boxes, preventing the crop seeds in these boxes from falling into their respective boxes. Only when the seed inlet on the seed tray is rotated to be directly below the seed box can the crop seeds in the seed box fall into the seed tube 23.

[0063] Subsequently, the crop seeds enter the seed collection mechanism 3 through the seed drop tube 23, and under the guidance of the inoculation wall 313 and the seed collection wall 322, they fall into the soil through the seed supply port 323 at the bottom.

[0064] Example 2

[0065] like Figure 11As shown in the figure, the several modular automatic seed supply devices described in Embodiment 1 can be stacked vertically. The lower part of the seed collection mechanism 3 of the upper modular automatic seed supply device is inserted into the circular hole in the center of the adjacent lower modular automatic seed supply device. The seed collection mechanisms of the upper and lower devices are interconnected. That is to say, the crop seeds falling into the upper seed collection mechanism can pass through the lower seed collection mechanism in sequence and finally fall into the soil through the seed supply port at the bottom of the bottom seed collection mechanism.

[0066] The seed-dropping frame of the upper seed supply device is fixedly connected to the seed-embedded plate of the adjacent lower seed supply device by splicing thread 53.

[0067] When N automatic seed supply devices are connected one on top of the other, they can provide seeds for up to N*12 varieties in an orderly manner.

[0068] Everything else is the same as in Example 1.
