The air cylinder outlet head is located at the end of the outer wall of the air cylinder. The cylinder plunger, the rack, the plunger spring stopper and the air cylinder plunger sealing head constitute the air cylinder plunger, and the rack is meshed with the teeth of the half gear shaft. The seed pusher is sleeved on the lower end of the air cylinder outlet head.

[0015] The plunger spring guide column is embedded in the grooves of the left shell of the sowing mechanism and the right shell of the sowing mechanism through a protrusion at one end. The plunger spring is sleeved on the plunger guide column, and one end of the plunger spring is in contact with the bottom end surface of the plunger guide column, and the other end extends into the center hole of the barrel plunger.

[0016] The plunger mechanism is installed in the cylindrical groove reserved in the left shell of the sowing mechanism and the right shell of the sowing mechanism, and the axial movement and radial movement of the outer wall of the air cylinder are limited in the cylindrical groove. The reserved groove on the air outlet head of the air cylinder cooperates with the large round table protrusion on the left shell of the sowing mechanism and the right shell of the sowing mechanism.

[0017] The lower end of the seed pusher bracket is engaged with the seed pusher. The upper end of the seed pusher bracket is matched with the boss of the half gear shaft, and the hook in the middle of the seed pusher bracket is connected with the small round table bosses on the left shell of the sowing mechanism and the right shell of the sowing mechanism through a tension spring.

[0020] A method for using a spherical seed broadcasting device comprises the following steps:

[0021] Step 1. Use the power of an external power source to transmit the power to the seed box and the sowing component through the transmission component.

[0022] Step 2. The seed box stirs the seeds with a stirring wheel to prevent the seeds from getting stuck inside the seed box. The disordered seeds inside the seed box are orderly discharged from the seed outlet of the seed box through the gap reserved between the seed wheel and the seed box shell. The seeds move forward under the action of the seed wheel, and the subsequent seeds push the seeds in front to the predetermined position of the three-way component;

[0023] Step 3. The half-tooth shaft gear of the sowing component rotates using the power transmitted by the transmission component, and its teeth mesh with the rack of the plunger mechanism. Driven by the half-tooth shaft gear, the cylinder plunger moves toward the plunger spring guide column and gradually compresses the plunger spring. When the teeth of the half-tooth shaft gear rotate to the toothless part, the cylinder plunger moves toward the cylinder outlet head under the action of the plunger spring, and at the same time compresses the air between the outer wall of the cylinder and the cylinder plunger head, so that the compressed air is discharged from the cylinder outlet head.

[0024] Step 4. The boss of the half-tooth shaft gear rotates with the rotation of the half-tooth shaft gear, and the seed pusher bracket matched with the boss of the half-tooth shaft gear follows the movement. The movement of the seed pusher bracket drives the tension spring fixed on the small round table protrusion to stretch, and drives the seed pusher connected to the seed pusher bracket to move. When the boss contacts the seed pusher bracket, the seed pusher moves upward. When the boss does not contact the seed pusher bracket, the seed pusher moves downward under the action of the restoring force of the tension spring. This cycle continues, and the seed pusher head reciprocates on the air outlet head of the air cylinder.

[0025] Step 5. After the seeds reach the predetermined position, they then move toward the three-way seed stopper under the action of the seed pusher and stop at the three-way seed stopper. The seeds overcome the force of the torsion spring under the action of the compressed gas discharged from the air cylinder outlet head, push the three-way seed stopper open, and the seeds are discharged from the three-way component. This cycle is repeated to complete the seeding of all seeds in the seed box.

[0026] Beneficial effects of the present invention:

[0027] The present invention provides power through an external power source. The external power source is first connected to the power input shaft. The power input shaft transmits power to the seed stirring shaft through the inner synchronous belt and the inner synchronous pulley, driving the seed row wheel and the seed stirring wheel to work, and the seeds are sequentially entered into the three-way component from the seed box outlet from the seed box, and then the power is transmitted to the half-tooth shaft gear of the sowing component by the outer synchronous belt and the synchronous pulley.

[0028] The working half-tooth shaft gear drives the meshing rack and the air cylinder plunger fixedly connected to the rack, so that the compressed air discharged from the air cylinder outlet head, under the guidance of the three-way component channel, blows out the seeds that have been arranged in sequence at the predetermined positions of the three-way component to complete the sowing.

[0029] The present invention sows spherical seeds mainly including soybeans and pelletized seeds including corn, peanuts, etc., integrates the characteristics of a pneumatic precision seeder that does not damage seeds and sows with high precision, improves the mechanization level of spherical seed sowing, reduces the use of furrow openers and reduces soil disturbance.

The left outer shell 21 of the sowing mechanism and the right outer shell 22 of the sowing mechanism are fixedly connected by the nut 23 and the hexagon socket bolt 24, and the plunger spring guide column 25, the plunger spring 26, the plunger mechanism 27, the seed pusher bracket 28, the half gear shaft 29, the large bearing 210, the rectangular bearing end cover 211, the small bearing 212 and the tension spring 213 are all covered therein.

The air cylinder outlet head 275 is located at the end of the air cylinder outer wall 273 and has an interference fit with the air cylinder outer wall 273. The cylinder plunger 271, the rack 272, the plunger spring stopper 274 and the cylinder plunger sealing head 275 form the cylinder plunger, the rack 272 is meshed with the teeth 2902 of the half gear shaft 29, and the cylinder plunger moves upward to squeeze the plunger spring 26 under the drive of the half gear shaft 29.

The seed pusher 279 is jacketed at the lower end of the cylinder outlet head 278.

The reserved groove on the cylinder outlet head 278 cooperates with the large frustum protrusion 2105 on the left shell 21 of the sowing mechanism and the right shell 22 of the sowing mechanism, thereby limiting the circumferential rotation of the plunger mechanism 27.

[0057] The lower end of the seed pusher bracket 28 is engaged with the seed pusher 279, and the seed pusher 279 moves with the reciprocating motion of the seed pusher bracket 28, and is used to push the seeds inside the three-way component 1 to the three-way seed stopper 12.

[0060] The present invention also provides a method for using the spherical seed broadcasting device, comprising the following steps:

[0061] Step 1. Use the power of an external power source to transmit the power to the seed box 3 and the sowing component 2 through the transmission component 4.

[0062] Step 2. The seed box 3 uses the seed stirring wheel 37 to stir the seeds to prevent the seeds from getting stuck inside the seed box 3 and affecting the sowing effect. The disordered seeds inside the seed box 3 are discharged from the seed outlet of the seed box in an orderly manner through the gap reserved by the seed wheel 38 and the seed box shell 31. The seeds move forward under the action of the seed wheel 38, and the subsequent seeds push the seeds in front to the predetermined position of the three-way component 1 (enter the intersection of the horizontal section and the vertical section).

[0063] Step 3. The half-tooth shaft gear 29 of the sowing component 2 rotates using the power transmitted by the transmission component 4, and its tooth 2902 part meshes with the rack 272 of the plunger mechanism 27. Driven by the half-tooth shaft gear 29, the cylinder plunger moves toward the plunger spring guide column and gradually compresses the plunger spring 26. When the tooth 2902 of the half-tooth shaft gear 29 rotates to the toothless part, the cylinder plunger moves toward the cylinder outlet head 278 under the action of the plunger spring 26, and at the same time compresses the air between the cylinder outer wall 273 and the cylinder plunger head 275, so that the compressed air is discharged from the cylinder outlet head 278.

[0064] Step 4. The boss 2901 of the half-tooth shaft gear 29 rotates with the rotation of the half-tooth shaft gear 29, and the seed pusher bracket 28 matched with the boss 2901 of the half-tooth shaft gear 29 follows the movement. The movement of the seed pusher bracket 28 drives the tension spring 213 fixed on the small round table protrusion 2104 to stretch, and drives the seed pusher 279 connected to the seed pusher bracket 28 to move. When the boss 2901 contacts the seed pusher bracket 28, the seed pusher 279 moves upward. When the boss 2901 does not contact the seed pusher bracket 28, the seed pusher 279 moves downward under the action of the restoring force of the tension spring 213. This cycle continues, and the seed pusher 279 is sleeved on the air cylinder outlet head 278 and reciprocates.

[0065] Step 5. After the seeds reach the predetermined position (reaching the intersection of the horizontal section and the vertical section), they then move toward the three-way seed stopper 279 under the action of the seed pushing head 279 and stop at the three-way seed stopper. Under the action of the compressed gas discharged from the air cylinder outlet head 278, the seeds overcome the force of the torsion spring 13 and push the three-way seed stopper 12 open, and the seeds are discharged from the three-way component. This cycle is repeated to complete the seeding of all seeds in the seed box 3.

6. A method for using a spherical seed broadcasting device, characterized in that: The steps include: Step 1. Use the power of the external power source to transmit the power to the seed box and the sowing component through the transmission component; Step 2. The seed box stirs the seeds with a stirring wheel to prevent the seeds from getting stuck inside the seed box. The disordered seeds inside the seed box are orderly discharged from the seed outlet of the seed box through the gap reserved between the seed wheel and the seed box shell. The seeds move forward under the action of the seed wheel, and the subsequent seeds push the seeds in front to the predetermined position of the three-way component; Step 3. The half-toothed shaft gear of the sowing component rotates with the power transmitted by the transmission component, and its teeth mesh with the rack of the plunger mechanism. Driven by the half-toothed shaft gear, the cylinder plunger moves toward the plunger spring guide column and gradually compresses the plunger spring. When the teeth of the half-toothed shaft gear rotate to the toothless part, the cylinder plunger moves toward the cylinder outlet head under the action of the plunger spring, and at the same time compresses the air between the outer wall of the cylinder and the cylinder plunger seal head, so that the compressed air is discharged from the cylinder outlet head; Step 4. The boss of the half-toothed shaft gear rotates with the rotation of the half-toothed shaft gear, and the seed pusher bracket matched with the boss of the half-toothed shaft gear moves along with it. The movement of the seed pusher bracket drives the tension spring fixed on the small round table protrusion to stretch, and drives the seed pusher connected to the seed pusher bracket to move. When the boss contacts the seed pusher bracket, the seed pusher moves upward. When the boss does not contact the seed pusher bracket, the seed pusher moves downward under the action of the restoring force of the tension spring. This cycle repeats, and the seed pusher sleeve reciprocates on the air outlet head of the air cylinder. Step 5. After the seeds reach the predetermined position, they then move toward the three-way seed stopper under the action of the seed pusher and stop at the three-way seed stopper. The seeds overcome the force of the torsion spring under the action of the compressed gas discharged from the air cylinder outlet head, push the three-way seed stopper open, and the seeds are discharged from the three-way component. This cycle is repeated to complete the seeding of all seeds in the seed box.
