The outer surfaces of the sliding rods 203 are all sleeved with a telescopic spring 205, the two ends of the telescopic spring 205 are fixedly connected to the opposite surfaces of the leakage-proof plate 204 and the limiting sliding groove 202 respectively, the side of the leakage-proof plate 204 away from the feeding bin 201 is fixedly connected with a pressure receiving plate 206, and the side of the pressure receiving plate 206 away from the telescopic spring 205 is in an arc shape, the inner wall of the side of the seed box 102 close to the rotating disc 2 is fixedly connected with a pressing block 207, the pressing block 207 is located on the movement track of the arc-shaped side of the pressure receiving plate 206, and the center of the side of the rotating disc 2 away from the driving wheel 101 is provided with a driving assembly.

[0044] The driving assembly includes a worm gear 208, the worm gear 208 is fixedly connected to the center of the side of the rotating disc 2 away from the feeding bin 201, and the worm gear 208 is located outside the seed box 102, the inner wall of one side of the drill body 1 is rotationally connected with a transmission rod 2081, one end of the transmission rod 2081 is fixedly connected with a worm 2082 at equal intervals, the worm gear 208 is engaged with the worm 2082, the outer wall of the side of the drill body 1 close to the transmission rod 2081 is fixedly connected with a servo motor 2083, and the output shaft of the servo motor 2083 is fixedly connected to the transmission rod 2081.

[0045] The working process is as follows: first, the sowing personnel pour the Chinese medicine seeds to be sown into the seed box 102, and evenly spread them, so that the Chinese medicine seeds can be evenly distributed in the seed box 102, so that the plurality of feeding bins 201 can be filled with the Chinese medicine seeds to be sown, then the sowing personnel start the built-in motor to drive the drive wheel 101 to rotate, and make the drill body 1 move at a constant speed on the field, in this process, the furrow opener 105 is in contact with the field, and a groove is opened on the field by the front side of the furrow opener 105, then the sowing personnel start the servo motor 2083 to make it work and drive the transmission rod 2081 to rotate, the transmission rod 2081 drives the worm gears 208 engaged with it to rotate through the plurality of worms 2082 evenly distributed on it, so that the plurality of rotating discs 2 rotate synchronously, at this time, the plurality of feeding bins 201 arranged on each rotating disc 2 rotate evenly, when the feeding bin 201 rotates close to the bottom of the seed box 102, the feeding bin 201 extends into the Chinese medicine seeds evenly laid in the seed box 102, and a certain amount of Chinese medicine seeds are filled in the space inside the feeding bin 201, then with the uniform rotation of the rotating disc 2, the feeding bin 201 filled with Chinese medicine seeds at the lowest part of the rotating disc 2 moves upward and gradually approaches the round port on the limiting sliding groove 202, when the corresponding pressure plate 206 below the feeding bin 201 filled with Chinese medicine seeds is in contact with the pressing block 207 on the inner wall of the seed box 102, the pressing block 207 constantly presses one side of the pressure plate 206 in the arc shape, so that the pressure plate drives the leakage-proof plate 204 to slide along the outer surface of the sliding rod 203 to the worm gear 208, and the extension spring 205 sleeved on the outer surface of the sliding rod 203 constantly shrinks under the extrusion of the leakage-proof plate 204, so that the leakage-proof plate 204 gradually moves away from the round port between the feeding bin 201 and the limiting sliding groove 202, so that the Chinese medicine seeds in the feeding bin 201 can fall into the discharge pipe 103 from the inside of the round port, and finally fall into the groove opened by the furrow opener 105, and the plurality of feeding bins 201 on each rotating disc 2 are aligned with the round port through the rotating range of the rotating disc 2, and a certain amount of Chinese medicine seeds are put into the groove from the discharge pipe 103, and the drill body 1 is driven by the drive wheel 101 to move at a constant speed, so that a certain amount of Chinese medicine seeds can be evenly put into the groove, so that the Chinese medicine seeds can be sown in a certain amount and at an equal distance, avoiding the situation that the seed density in the groove is not uniform and the plant spacing in the groove is inconsistent when the Chinese medicine seeds are sown by the strip sowing method, thereby effectively improving the land utilization rate.

[0046] Embodiment two: please refer to Figures 8 to 12 and Figure 16As shown, a lifting mechanism is provided on the main body 1 of the strip seeder. The lifting mechanism includes a reciprocating screw 3, which is rotatably connected to the inner wall of the main body 1 of the strip seeder. The reciprocating screw 3 is located directly above the mounting plate 104. A limit rod 301 is fixedly connected between opposite surfaces of the main body 1 of the strip seeder. The limit rod 301 is located directly above the reciprocating screw 3. A nut 302 is threadedly connected to the outer surface of the reciprocating screw 3. The end of the nut 302 away from the reciprocating screw 3 is slidably connected to the outer surface of the limit rod 301. A roller 303 is rotatably connected to the side of the nut 302 near the drive wheel 101. A ratchet 304 is fixedly connected to the outer surface of the reciprocating screw 3 and the transmission rod 2081, and the ratchet teeth of the ratchet 304 face opposite directions. A mounting ring 3041 is rotatably connected to the outer surface of the reciprocating screw 3 and the transmission rod 2081. A pawl 3042 is rotatably connected to one side of the mounting ring 3041. The claw-shaped part at the front end of the pawl 3042 engages with the tooth groove part of the ratchet 304. A synchronous pulley 3043 is fixedly connected to the outer surface of the mounting ring 3041. The outer surfaces of the synchronous pulley 3043 are connected by a synchronous belt 3044. The output shaft of the servo motor 2083 is fixedly connected to the side of the mounting ring 3041 away from the strip seeder body 1.

[0047] The inner wall of the strip seeder body 1 has symmetrically formed grooves 305. The mounting plate 104 is slidably connected inside the grooves 305. Support springs 306 are symmetrically fixed between the bottom of the mounting plate 104 and the inner wall of the grooves 305. A lifting plate 307 is fixedly connected to the top of the mounting plate 104. The top of the lifting plate 307 is inclined, and the vertical height of the lifting plate 307 increases gradually from the side closer to the synchronous belt 3044 to the side farther away. The outer surface of the roller 303 is adapted to the inclined top of the lifting plate 307. The inclined surface of the top of the lifting plate 307 has equidistant mounting slots 308. The bottom of the mounting slots 308 is fixedly connected to the mounting rod 309. A trigger block 310 is slidably connected inside the mounting slots 308. The top of the trigger block 310 is horizontal and is used to provide a holding position for the roller 303 on the inclined surface of the lifting plate 307 to facilitate the subsequent equidistant lifting of the furrow opener 105. A return spring 311 is fitted onto the outer surface of the mounting rod 309. The two ends of the return spring 311 are fixedly connected to the bottom of the trigger block 310 and inside the mounting groove 308. A trigger rod 312 is fixedly connected to the bottom of the trigger block 310, and a tactile switch 313 is fixedly connected to the bottom of the mounting groove 308. The tactile switch 313 is located on the movement trajectory of the trigger rod 312.

The tactile switch 313 is electrically connected to the warning lights 314, and their opening and closing are controlled by a controller.

[0048] Working process: when the distance between the opener 105 and the field needs to be adjusted, the seeder first starts the servo motor 2083 in reverse rotation, the output shaft of the servo motor 2083 drives the mounting ring 3041 on the transmission rod 2081 to rotate in reverse, at this time, the pawl 3042 on the mounting ring 3041 cannot be engaged with the ratchet wheel 304 on the transmission rod 2081, so that the mounting ring 3041 cannot drive the transmission rod 2081 to rotate synchronously, therefore the plurality of rotating discs 2 in the seed box 102 cannot rotate synchronously, in this process, the mounting ring 3041 drives the synchronous wheel I 3043 on it to rotate, then the synchronous wheel I 3043 drives the synchronous wheel I 3043 on the reciprocating lead screw 3 through the synchronous belt I 3044 on it to rotate, so that the mounting ring 3041 on the reciprocating lead screw 3 rotates in the same direction, at this time, the pawl 3042 on the mounting ring 3041 is engaged with the ratchet wheel 304 on the reciprocating lead screw 3, so that the reciprocating lead screw 3 rotates in the same direction, then the nut 302 on the reciprocating lead screw 3 slides along the outer surface of the limiting rod 301 away from the synchronous wheel I 3043, and the roller 303 on the nut 302 rolls horizontally along the inclined surface on the top of the lifting plate 307 at a constant speed, the roller 303 gradually extrudes the lifting plate 307, rolls from the lowest part of the inclined surface on the top of the lifting plate 307 to a relatively higher position, and moves to the top of the trigger block 310 located thereon, at this time, the lifting plate 307 moves downward at a constant speed under the extrusion of the roller 303, then the mounting plate 104 pushes the mounting plate 104 to move vertically downward along the groove 305, and the mounting plate 104 drives the plurality of openers 105 to move vertically downward synchronously, and extrudes the supporting spring 306 in the groove 305 to shrink under stress, so that the opener 105 can move downward by a certain distance, similarly, as the roller 303 continues to translate, the roller 303 rolls to a higher position of the lifting plate 307, so that the roller 303 can make the opener 105 move downward by the same distance each time it rolls to a trigger block 310 on the top of the lifting plate 307, in this process, when the roller 303 rolls from the lowest end of the top of the lifting plate 307 to the trigger block 310 on the top of the lifting plate 307, and from the lower end of the trigger block 310 to the relatively higher end of the trigger block 310, the roller 303 contacts the trigger block 310 and extrudes the trigger block 310 to move vertically along the outer surface of the mounting rod 309, at this time, the reset spring 311 sleeved on the mounting rod 309 is stressed to shrink, and the trigger lever 312 at the bottom of the trigger block 310 moves downward and approaches the micro switch 313 in the mounting groove 308, then the trigger lever 312 extrudes the micro switch 313 to connect the circuit of the warning lamp 314 electrically connected thereto, and the controller turns on the warning lamp 314, so as to remind that the opener 105 has been adjusted to the required position, when the roller 303 is separated from the horizontal end of the lower part of the top of the lifting plate 307,The reset spring 311 inside the installation groove 308 here is constantly elongated upward due to the loss of extrusion of the roller 303, the reset spring 311 pushes the trigger block 310 to move vertically upward along the outer surface of the installation rod 309, and makes the trigger rod 312 at the bottom of the trigger block 310 gradually disengage from the touch switch 313, thereby making the circuit of the warning light 314 electrically connected thereto be disconnected, and the warning light 314 is turned off by the controller, so that the depth of the furrow opener 105 can be adjusted equidistantly by using the lifting plate 307 to displace multiple times by the same distance, and the sowing personnel can also be reminded in time that the furrow opener 105 has been adjusted to the position, thereby being able to adapt to the plowing depth conditions required by different varieties of Chinese herbal seed sowing, and effectively reducing the time required for adjustment, so as to increase the effective working time and improve the overall working efficiency, and the warning light 314 can more prominently remind the worker of the depth of the furrow opener 105 adjusted from the visual aspect, preventing the worker from adjusting too deep or too shallow due to difficulty in grasping the depth during manual adjustment, which not only can improve the safety of the working process, but also can reduce the workload of the sowing personnel.

[0049] When the roller 303 moves to the highest position of the inclined surface at the top of the lifting plate 307, the reciprocating lead screw 3 drives the roller 303 to move in the opposite direction along the inclined surface at the top of the lifting plate 307 through the nut 302, and the lifting plate 307 can be moved upward by the same distance multiple times, thereby adjusting the position of the furrow opener 105 upward equidistantly.

[0050] Embodiment three: please refer to Figures 13 to 15 As shown in the figure, the drill body 1 is provided with a uniform soil covering mechanism, the uniform soil covering mechanism comprises a plurality of collection bins 4 arranged equidistantly, and the opening of the plurality of collection bins 4 is open, which is used for collecting the soil covered by the furrow opener 105. The plurality of collection bins 4 are fixedly connected equidistantly in the drill body 1, and the connecting rod 401 is rotatably connected between the bottoms of the drill body 1. The first soil turning cylinder 402 and the first gear 403 are fixedly connected equidistantly on the outer surface of the connecting rod 401 in sequence, the first soil turning cylinder 402 is located inside the collection bin 4, and the first gear 403 is located outside the collection bin 4. The second soil turning cylinder 404 is rotatably connected inside the collection bin 4, the second soil turning cylinder 404 is located obliquely above the first soil turning cylinder 402, and the first soil turning cylinder 402 is located obliquely above the ground roller 106. The rotating shaft of the second soil turning cylinder 404 is fixedly connected with the second gear 405, the second gear 405 is located outside the collection bin 4, and the first gear 403 is engaged with the second gear 405. The outer surfaces of the connecting rod 401 and the rotating shaft of the ground roller 106 are both fixedly connected with the second synchronous pulley 406, and the outer surfaces of the second synchronous pulley 406 are drivingly connected through the second synchronous belt 407.

[0051] Working process: when the drill body 1 advances at a constant speed, the ground roller 106 is driven to roll along the surface of the field in the same direction. When the ground roller 106 rolls at a constant speed in the same direction as the drill body 1, the collection bin 4 can guide the soil turned up by the furrow opener 105 to the middle part thereof. The synchronous wheel two 406 on the rotating shaft of the ground roller 106 also rotates in the same direction. The synchronous wheel two 406 on the connecting rod 401 rotates through the synchronous belt two 407 thereon. The plurality of first soil turning cylinders 402 on the connecting rod 401 also rotate in the same direction. Thus, the plurality of first soil turning cylinders 402 can tilt the soil turned up by the furrow opener 105 upward to the inside of the collection bin 4. At the same time, the plurality of first gears 403 on the connecting rod 401 also rotate in the same direction. Then, the first gears 403 drive the second gears 405 engaged therewith to rotate, and make the second gears 405 rotate in the opposite direction with the first gears 403. In turn, the second gears 405 drive the second soil turning cylinders 404 to rotate in the same direction. Thus, the first soil turning cylinders 402 and the second soil turning cylinders 404 rotate relative to each other, and the lumps of soil in the soil are turned and crushed by the protrusions thereon. Thus, the particles of the soil covering the Chinese medicinal seeds can be smaller, which can avoid the lumps of soil pressing on the Chinese medicinal seeds to prevent them from germinating and growing effectively, and can also avoid the soil covering the Chinese medicinal seeds being too deep to affect the respiration and germination of the Chinese medicinal seeds, thereby improving the germination rate and the uniformity of the Chinese medicinal seeds. Meanwhile, the soil can be evenly covered on each Chinese medicinal seed by the first soil turning cylinders 402 and the second soil turning cylinders 404 turning the soil together, thereby improving the air permeability and water permeability of the soil, so that the Chinese medicinal seeds can obtain sufficient oxygen and water during the germination process, thereby effectively improving the germination rate of the Chinese medicinal seeds.

[0052] When the fine soil covering the Chinese medicinal seeds is completed, the ground roller 106 rolling at a constant speed extrudes and crushes the soil downward, and lightly presses the soil by the weight of the ground roller 106, so that the soil is tightly combined with the seeds, thereby becoming the sowing work of the Chinese medicinal seeds.

[0053] The above has carried on the detailed introduction to the present application, the principle and implementation mode of the present application are described by applying specific examples in this paper, the above example is only used to help understanding the method and its core idea of the present application; at the same time, for the general technical personnel in the art, according to the idea of the present application, the specific implementation mode and application range will be changed, and the above description should not be understood as the limitation of the present application.
