[0061] Reference Figures 1-12 One of the embodiments of the present application provides a cotton seeding device, comprising:

[0062] The protective shell 100 is connected in a ring shape with a plurality of seeding boxes 300 to form a seeding ring 200.

[0063] The seeding ring 200 is installed in the protective shell 100 and forms a seed storage area 110 in the protective shell 100;

[0064] The seed storage area 110 is provided with a rotating assembly 400 connected with the seeding ring 200 for driving the seeding ring 200 to rotate;

[0065] The protective shell 100 has a seed inlet 120 and a seed outlet 130 communicating with the seed storage area 110, and the seeds are uniformly dropped into the seed outlet 130 by the rotating seeding ring 200 for uniform seeding;

[0066] The rotating assembly 400 is driven by an external driving mechanism.

[0067] In this embodiment, the external driving mechanism (not shown in the figure) can adopt a motor and a speed reducer, and the motor and the speed reducer are cooperated to drive the rotating assembly 400 to rotate, so as to drive the seeding ring 200 to rotate.

[0068] Specifically, as shown in Figures 1-5 The cotton seeding device is composed of a protective shell 100 and a seeding ring 200; the protective shell 100 has a seed inlet 120 and a seed outlet 130, the seed inlet 120 is used for inputting seeds, and the seed outlet 130 is used for discharging seeds for uniform seeding; the seeding ring 200 is composed of a plurality of independent seeding boxes 300 through annular connection; when the seeding ring 200 is installed in the protective shell 100, a seed storage area 110 is formed in the protective shell 100, the seed storage area 110 communicates with the seed inlet 120 and the seed outlet 130, and the seeds input by the seed inlet 120 enter the seed storage area 110; the rotating assembly 400 is arranged in the seed storage area 110, the rotating assembly 400 is connected with the protective shell 100 and the seeding ring 200 respectively, and the rotating assembly 400 is driven to rotate by an external motor and speed reducer, the rotating assembly 400 drives the seeding ring 200 connected therewith to rotate in the protective shell 100, so that the seeds in the seed storage area 110 fall into the plurality of seeding boxes 300 in the seeding ring 200 under the action of gravity, and the seeds in the plurality of seeding boxes 300 fall into the seed outlet 130 in sequence during the rotation, so as to perform uniform seeding. The cotton seeding device in this embodiment can automatically and accurately drop cotton seeds for seeding through the unique structure design of the seeding ring 200, improves the planting efficiency and reduces the labor cost, improves the accuracy of seed dropping, ensures the uniform distribution and appropriate density of seeds, and effectively reduces the problems of seed jamming and breakage rate.

[0069] In one embodiment, a trigger protrusion 500 is fixedly installed inside the protective housing 100;

[0070] A trigger switch 600 is provided on the sowing ring 200. When the rotating component 400 drives the sowing ring 200 to rotate and the trigger switch 600 on the sowing ring 200 is in contact with the trigger protrusion 500, the trigger switch 600 is triggered, causing the seeds in the seed storage area 110 to fall into the sowing ring 200.

[0071] When the trigger switch 600 on the sowing ring 200 is reset, the seeds located in the sowing ring 200 fall into the seed outlet 130 to complete the sowing.

[0072] In this embodiment, as Figures 3-6 As shown, specifically, a trigger protrusion 500 is provided inside the protective housing 100, and the trigger protrusion 500 is fixedly connected to the inner side of the protective housing 100; several trigger switches 600 are provided on the side of the sowing ring 200 near the trigger protrusion 500, and the several trigger switches 600 are respectively connected to several sowing boxes 300. The number of trigger switches 600 is the same as the number of sowing boxes 300. Each trigger switch 600 is used to trigger the sowing box 300 connected to it to perform seed feeding / discharging. The trigger switches 600 are in the shape of levers, such as... Figure 4When the rotating assembly 400 is driven by the motor and the speed reducer to rotate and the seeding ring 200 connected therewith is rotated, a plurality of trigger switches 600 provided on the seeding ring 200 will rotate with the seeding ring 200. Since the trigger protrusions 500 are in a fixed state, each trigger switch 600 on the seeding ring 200 will be in contact with the fixed trigger protrusions 500 in turn in the process of rotation. When one of the trigger switches 600 is in contact with the trigger protrusions 500, the trigger switch 600 will trigger the seeding box 300 connected therewith, so that the seeds in the seed storage area 110 enter the inside of the seeding box 300. Since the seeding ring 200 is in a state of continuous rotation, when the seeding ring 200 drives the trigger switch 600 to leave the trigger protrusions 500, the trigger switch 600 is in a non-contact state with the trigger protrusions 500. When the trigger switch 600 is in a non-contact state with the trigger protrusions 500, the trigger switch 600 will drive the seeding box 300 connected therewith to reset. When the seeding box 300 is reset, the seeds in the inside of the seeding box 300 will fall into the seed outlet 130 under the action of gravity, so as to uniformly seed. In this embodiment, the trigger protrusions 500 and a plurality of trigger switches 600 which are the same number as the seeding boxes 300 are arranged to trigger each seeding box 300 in turn, so as to complete the feeding and discharging of each seeding box 300 in turn, so as to achieve the effect of uniform seeding, ensure the uniform distribution and proper density of seeds, and effectively reduce the problem of seed jamming.

[0073] In one embodiment, the protective shell 100 is provided with a first support shaft 140;

[0074] The trigger protrusions 500 are fixedly installed on the cylindrical surface of the first support shaft 140, and are close to the seed outlet 130.

[0075] In this embodiment, as shown in Figure 5 、 Figure 6As shown, specifically, a first support shaft 140 is arranged in the protective shell 100, the first support shaft 140 is a through shaft to facilitate the installation of the driving mechanism; since the seed outlet 130 on the protective shell 100 is arranged at the lower end, the trigger protrusion 500 is fixedly arranged on the cylindrical surface of the first support shaft 140, and is arranged at the lower end of the first support shaft 140 close to the position of the seed outlet 130. The trigger protrusion 500 has the beneficial effect of: controlling the feeding and discharging of the seed box 300, so that the feeding and discharging can be accurately completed when the seed box 300 is rotated to a position above the seed outlet 130. When the seed ring 200 rotates and drives the trigger switch 600 connected thereto to rotate to the position of the trigger protrusion 500, the trigger switch 600 is in contact with the trigger protrusion 500, and the trigger switch 600 drives the seed box 300 connected thereto to trigger, so that the seeds in the seed storage area 110 enter the inside of the seed box 300. Since the seed ring 200 is in a state of continuous rotation, when the seed ring 200 drives the trigger switch 600 away from the trigger protrusion 500, the trigger switch 600 is in a non-contact state with the trigger protrusion 500. When the trigger switch 600 is in a non-contact state with the trigger protrusion 500, the trigger switch 600 drives the seed box 300 connected thereto to reset. When the seed box 300 is reset, the seeds in the inside of the seed box 300 fall into the seed outlet 130 under the action of gravity.

[0076] In one embodiment, two opposite sides of each seed box 300 are respectively provided with a limiting protrusion 311 and a first limiting clamping groove 312 for connecting with adjacent seed boxes 300;

[0077] Each seed box 300 is fixedly connected with adjacent seed boxes 300 through the limiting protrusion 311 and the first limiting clamping groove 312, and a plurality of seed boxes 300 are connected in a ring shape to form a seed ring 200.

[0078] In this embodiment, each seed box 300 in the seed ring 200 formed by a plurality of seed boxes 300 connected in a ring shape is connected with adjacent seed boxes 300 in a clamping manner to form the whole seed ring 200.

[0079] Specifically, as shown in FIG. 1, the seed ring 200 is arranged in the seed ring groove 120 of the protective shell 100, and the seed ring 200 is arranged in the seed ring groove 120 of the protective shell 100 in a clamping manner through the limiting protrusion 311 and the first limiting clamping groove 312. Figures 3-4 、 Figures 9-11As shown, in a single seeding box 300, limiting protrusions 311 and first limiting slots 312 are provided on two opposite sides. When connected to an adjacent seeding box 300, the limiting protrusions 311 on the individual seeding box 300 engage with the first limiting slots 312 of the adjacent seeding box 300, thus connecting several seeding boxes 300 sequentially. Since the upper and lower end faces of a single seeding box 300 are arc-shaped and its left and right end faces are inclined, several seeding boxes 300 are connected sequentially until the limiting protrusions 311 of the last seeding box 300 engage with the first limiting slots 312 of the first seeding box 300, forming a closed loop, thus connecting to form an integral seeding ring 200. The integral seeding ring 200, by adopting this connection method, facilitates installation and disassembly and provides stable operation.

[0080] In one embodiment, a single seed box 300 includes a seed inlet 310 and a swing seed outlet assembly 320;

[0081] The limiting protrusion 311 and the first limiting slot 312 are both provided on the outer surface of the seed inlet chamber 310;

[0082] A rotating shaft 330 is provided inside the seed inlet chamber 310, and the swinging seed outlet component 320 is installed on the rotating shaft 330. The swinging seed outlet component 320 is installed inside the seed inlet chamber 310 through the rotating shaft 330.

[0083] The trigger switch 600 is fixedly connected to one end of the drive shaft passing through the seed inlet chamber 310, and is used to trigger the rotation of the swing seed outlet assembly 320.

[0084] In this embodiment, a single seeding box 300 consists of a seed inlet chamber 310 and a swinging seed dispensing component 320. After seeds are input into the seed storage area 110 inside the protective shell 100, the input seeds will concentrate at the bottom of the seed storage area 110 under the action of gravity. However, since the overall seeding ring 200 is in a rotating state, the seeds will be evenly distributed on the seed inlet chamber 310 of each seeding box 300 during the rotation process.

[0085] Specifically, such as Figures 9-11 As shown, the limiting protrusion 311 and the first limiting slot 312 on the individual seeding box 300 are located on the outer side of the seed inlet body 310 and are arranged opposite to each other.

[0086] The other two sides of the seed feeding bin body 310 (adjacent to the limiting protrusion and the first limiting clamping groove) are provided with mounting holes, a rotating shaft 330 is arranged on the mounting holes, the seed feeding assembly 320 is also provided with mounting holes, the seed feeding assembly 320 is arranged in the seed feeding bin body 310, one end of the rotating shaft 330 is arranged to pass through the mounting hole of the seed feeding assembly 320, and the other end of the rotating shaft 330 is arranged on the outside of the seed feeding bin body 310; the rotating shaft 330 is a hexagonal rotating shaft, and when the rotating shaft 330 rotates, the seed feeding assembly 320 arranged on the rotating shaft 330 can be driven to rotate.

[0087] The end of the rotating shaft 330 on the outside of the seed feeding bin body 310 is connected with the trigger switch 600, when the trigger switch 600 is in contact with the trigger protrusion 500, the trigger switch 600 is swung, so that the rotating shaft 330 connected with the trigger switch 600 is followed to rotate, and the seed feeding assembly 320 is driven to rotate by the rotating shaft 330; in the rotating process of the seed feeding assembly 320, the seeds on the seed feeding bin body 310 enter the seed feeding assembly 320; when the trigger switch 600 is reset, the rotating shaft 330 and the seed feeding assembly 320 are reset, so that the seeds in the seed feeding assembly 320 fall into the seed outlet 130 to be sowed.

[0088] Because the seeds are distributed in the seed feeding bin body 310 of each seed sowing box 300, and the whole seed sowing ring 200 is in a rotating state, the trigger switch 600 connected with each seed sowing box 300 will fall the seeds distributed by the trigger switch 600 into the seed outlet 130 to be sowed after the trigger switch 600 is in contact with the trigger protrusion 500 and is reset, so that the uniform sowing effect is achieved.

[0089] In one embodiment, the seed feeding assembly 320 comprises an arc-shaped connecting seat 321, a supporting seat 322 and an elastic member 323.

[0090] The arc-shaped connecting seat 321 is arranged on the rotating shaft 330;

[0091] The supporting seat 322 is fixed in the seed feeding bin body 310;

[0092] One end of the elastic member 323 is arranged on the supporting seat 322, and the other end of the elastic member 323 is connected with the arc-shaped connecting seat 321;

[0093] The arc-shaped surface of the arc-shaped connecting seat 321 is provided with a seed hole 324.

[0094] When the trigger switch 600 is in contact with the trigger protrusion 500, the trigger switch 600 is triggered, and the seeds in the seed storage area 110 fall into the seed hole 324;

[0095] When the trigger switch 600 is in a non-contact state with the trigger protrusion 500, the elastic element 323 drives the trigger switch 600 to reset, so that the seeds in the seed hole 324 fall into the seed outlet 130 to complete the sowing.

[0096] In this embodiment, as Figures 9-11 As shown, specifically, the swing seed dispensing assembly 320 consists of an arc-shaped connecting seat 321, a support seat 322, and an elastic element 323, which is a spring. The mounting hole of the swing seed dispensing assembly 320 is located on the arc-shaped connecting seat 321, which is mounted on a rotating shaft 330. The rotating shaft 330 drives the arc-shaped connecting seat 321 to rotate. A seed hole 324 is provided on the arc surface of the arc-shaped connecting seat 321 for seed insertion. The size of the seed hole 324 can be designed according to the size of the seeds to ensure that only one seed enters the swing seed dispensing assembly 320 each time, thus ensuring the sowing density. The support seat 322 is fixedly installed on one side inside the seed inlet chamber 310, which is the turning side of the arc-shaped connecting seat 321 when rotating. The elastic element 323 is sleeved on the support seat 322 to reset the arc-shaped connecting seat 321 after rotation.

[0097] like Figure 10 , Figure 11 As shown, Figure 10 To trigger the initial position of the arc-shaped connector 321, the opening of the seed hole 324 faces the seed outlet 130. Figure 11 After triggering, the arc-shaped connecting seat 321 is positioned such that the opening of the seed hole 324 faces the seed storage area 110. Before triggering, the seeds distributed in the seed inlet chamber 310 of each seed box 300 are located on the arc-shaped connecting seat 321. When the trigger switch 600 contacts the trigger protrusion 500, the trigger switch 600 swings, causing the connected rotating shaft 330 to rotate accordingly. The rotating shaft 330 drives the arc-shaped connecting seat 321 mounted on it to rotate accordingly, causing the seed hole 324 of the arc-shaped connecting seat 321 to rotate upward. At this time, one side of the arc-shaped connecting seat 321 presses against the elastic element 323, and the seeds located in the seed inlet chamber 310 fall into the seed hole 324. Since the size of the seed hole 324 is determined according to the seed size... The size is designed so that only one seed enters the seed hole 324. When the trigger switch 600 and the trigger protrusion 500 are not in contact, the arc-shaped connecting seat 321 rebounds and resets under the elastic force of the elastic element 323, causing the trigger switch 600 to reset as well. The seed hole 324 on the arc-shaped connecting seat 321 also resets, and the seed in the seed hole 324 falls into the seed outlet 130 under the action of gravity, thus completing the sowing. The other sowing boxes 300 are sown in the same way. Since the overall sowing ring 200 is in a rotating state, each sowing box 300 can complete the sowing in sequence, achieving the effect of uniform sowing.

[0098] In one embodiment, a second support shaft 150 is provided inside the protective housing 100, and one end of the rotating component 400 is sleeved on the second support shaft 150 and rotatably connected to the second support shaft 150.

[0099] The other end of the rotating component 400 is fixedly connected to the seeding ring 200, and the rotating component 400 drives the seeding ring 200 to rotate.

[0100] In this embodiment, as Figure 5 As shown, specifically, a second support shaft 150 is provided inside the protective housing 100. The second support shaft 150 is coaxial with the first support shaft 140 and is also a through shaft to facilitate the installation of the drive mechanism. One end of the rotating assembly 400 is mounted on the second support shaft 150, which supports the rotating assembly 400 to ensure its stability during rotation. The other end of the rotating assembly 400 is fixedly connected to the seeding ring 200. When the rotating assembly 400 is driven to rotate by an external drive mechanism, since one end of the rotating assembly 400 is fixedly connected to the seeding ring 200, it will cause the seeding ring 200 to rotate accordingly.

[0101] In one embodiment, the rotating assembly 400 includes a connecting sleeve 410 and a plurality of connecting rods 420 arranged around the circumference of the connecting sleeve 410.
