Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine planting, and specifically provides a seeding device for traditional Chinese medicine planting with depth adjustment. Background Art

[0002] The seeding methods for traditional Chinese medicine include drilling, hill dropping, broadcasting, etc. Drilling is a seeding method in which furrows are directly opened on the ridge or on the raised bed at a certain row spacing, and the seeds are scattered into the furrows. It is suitable for mechanized management and is the most commonly used method for seeding medicinal materials. Generally, this method can be used for seeding all medicinal material varieties. Hill dropping is a method of opening holes on the raised bed at a certain plant spacing in rows or at a certain plant spacing on the ridge, and putting 2-3 seeds in each hole. Currently, when seeding traditional Chinese medicine seeds, a drilling machine is usually used to plant by the drilling method. However, since the existing drilling machine may not be able to effectively control the feeding amount during seeding, the amount of seeds fed each time may be too much or too little, resulting in uneven distribution of the number of seeds in the furrows. As a result, in places where the number of seeds is large, the plants will be crowded after emergence, competing for nutrients, light, and space, thus affecting the individual growth and development. In places where the number of seeds is scarce, there will be missing plants and ridges, reducing the land utilization rate and yield. In addition, if the feeding amount of the existing drilling machine is too much, it may also cause the accumulation of too many seeds in the seed cup and the seed delivery tube, resulting in blockage. Moreover, too little feeding amount or blockage in the seed cup and the seed delivery tube will make the plant spacing between the traditional Chinese medicine plants in the furrows inconsistent, which will further affect the overall yield and quality of traditional Chinese medicine planting and waste land resources. Summary of the Invention

[0003] In view of this, aiming at the deficiencies of the prior art, the present invention provides a seeding device for traditional Chinese medicine planting with depth adjustment to solve the problems that the uneven number of seeds and inconsistent plant spacing of the drilling machine when seeding traditional Chinese medicine seeds affect the overall yield and quality of traditional Chinese medicine.

Furthermore, it can avoid the clumped soil blocks in the soil covering squeezing the traditional Chinese medicine seeds so that they cannot germinate and grow effectively, and can also avoid the soil covering on the traditional Chinese medicine seeds being too deep, which affects the respiration and germination of the traditional Chinese medicine seeds. Furthermore, it can improve the germination rate and the uniformity of seedling emergence of the traditional Chinese medicine seeds. At the same time, it can make the soil covering evenly cover each traditional Chinese medicine seed, and then improve the air permeability and water permeability of the soil, enabling the traditional Chinese medicine seeds to obtain sufficient oxygen and water during the germination process, thereby effectively increasing the germination rate of the traditional Chinese medicine seeds.

Detailed implementation manners

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0021] Embodiment 1: Please refer to Figures 1 to 7 As shown, to solve the problems mentioned in the technical solutions, the embodiment of the present application provides a seeding device for traditional Chinese medicine planting with depth adjustment, including a drill seeder body 1. On one side of the drill seeder body 1, driving wheels 101 are symmetrically and rotatably connected, and a driving motor is built in the driving wheels 101 to supply power for the movement of the drill seeder body 1. A seed box 102 is fixedly connected to the top of the drill seeder body 1. On the outer wall of one side of the seed box 102 close to the driving wheels 101, a plurality of blanking pipes 103 are fixedly connected at equal intervals. An installation plate 104 is slidably connected up and down in the drill seeder body 1. At the bottom of the installation plate 104, a plurality of furrow openers 105 are fixedly connected at equal intervals. The furrow openers 105 are sleeved on the blanking pipes 103. A land roller 106 is rotatably connected to one side of the drill seeder body 1 away from the driving wheels 101. Among them, the plurality of blanking pipes 103 are of two-section type, and the upper part of the blanking pipe 103 is in sliding fit with its lower part, which is used to ensure the normal blanking of traditional Chinese medicine seeds.

[0022] An equal - amount feeding mechanism is arranged inside the seed box 102. The equal - amount feeding mechanism includes a plurality of turntables 2 arranged at equal intervals. The plurality of turntables 2 are all rotatably connected to the inner wall of the seed box 102 on the side close to the driving wheel 101. On the side of each turntable 2 away from the driving wheel 101, a plurality of feeding bins 201 are fixedly connected at equal intervals in a ring shape. And on the side of the turntable 2 away from the feeding bin 201, a plurality of limiting sliding grooves 202 are opened at equal intervals in a ring shape. The feeding bin 201 is communicated with the limiting sliding groove 202 through the opened round holes. Inside each limiting sliding groove 202, sliding rods 203 are symmetrically and fixedly connected. A leakage - proof plate 204 is slidably connected to the outer surfaces of every two sliding rods 203. The leakage - proof plate 204 is adapted to the limiting sliding groove 202, and the number of the leakage - proof plates 204 is the same as that of the limiting sliding grooves 202. And the leakage - proof plate 204 covers the outside of the round holes on the limiting sliding grooves 202. It is used to prevent Chinese medicine seeds from leaking into the limiting sliding grooves 202 and prevent the situation that the Chinese medicine seeds are crushed during the rotation of the turntable 2 in the seed box 102. Expansion springs 205 are sleeved on the outer surfaces of the sliding rods 203. The two ends of the expansion spring 205 are respectively fixedly connected to the opposite surfaces of the leakage - proof plate 204 and the limiting sliding groove 202. A pressure - receiving plate 206 is fixedly connected to the side of the leakage - proof plate 204 away from the feeding bin 201. And the side of the pressure - receiving plate 206 away from the expansion spring 205 is arc - shaped. A pressing block 207 is fixedly connected to the inner wall of the seed box 102 close to the turntable 2. The pressing block 207 is located on the movement track of the arc - shaped side of the pressure - receiving plate 206. A driving assembly is arranged at the center of the side of the turntable 2 away from the driving wheel 101.

[0023] The driving assembly includes a worm gear 208. The worm gear 208 is fixedly connected to the center of the side of the turntable 2 away from the feeding bin 201. And the worm gear 208 is located outside the seed box 102. A transmission rod 2081 is rotatably connected to the inner wall of one side of the drill seeder body 1. One end of the transmission rod 2081 is fixedly connected with a plurality of worm shafts 2082 at equal intervals. The worm gear 208 is meshed with the worm shafts 2082. A servo motor 2083 is fixedly connected to the outer wall of the drill seeder body 1 close to the transmission rod 2081. The output shaft of the servo motor 2083 is fixedly connected to the transmission rod 2081.

[0024] Working process: First, the sowing operator pours the traditional Chinese medicine seeds to be sown into the interior of the seed box 102 and spreads them out horizontally so that the traditional Chinese medicine seeds are evenly distributed inside the seed box 102. In this way, multiple feeding bins 201 can be filled with the traditional Chinese medicine seeds to be sown. Then, the sowing operator starts the built-in motor to make the driving wheel 101 start to rotate, and makes the drill seeder body 1 move forward at a constant speed on the field. During this process, the furrow opener 105 comes into contact with the field and uses its front side to open a groove on the field. Subsequently, the sowing operator starts the servo motor 2083 to make it start working and drive the transmission rod 2081 to rotate. The transmission rod 2081 drives the worm gear 208 engaged with it to rotate through a plurality of equally spaced worms 2082 arranged thereon, so that the multiple turntables 2 rotate synchronously. At this time, the multiple feeding bins 201 arranged on each turntable 2 rotate evenly. When the feeding bin 201 rotates to be close to the bottom of the inner cavity of the seed box 102, the feeding bin 201 extends into the evenly spread traditional Chinese medicine seeds in the seed box 102 and fills a certain amount of traditional Chinese medicine seeds by using the internal space of the feeding bin 201. Subsequently, with the uniform rotation of the turntable 2, the feeding bin 201 filled with traditional Chinese medicine seeds at the lowest position of the turntable 2 continuously moves upward and gradually approaches the circular opening on the limit sliding groove 202. When the pressure receiving plate 206 corresponding to the lower part of the feeding bin 201 filled with traditional Chinese medicine seeds comes into contact with the pressure applying block 207 on the inner wall of the seed box 102, the pressure applying block 207 continuously presses one side of the arc shape of the pressure receiving plate 206, so that the pressure receiving block drives the anti-leakage plate 204 to slide along the outer surface of the sliding rod 203 towards the worm gear 208, and the telescopic spring 205 sleeved on the outer surface of the sliding rod 203 is continuously compressed by the anti-leakage plate 204. Thus, the anti-leakage plate 204 gradually moves away from the circular opening between the feeding bin 201 and the limit sliding groove 202, so that the traditional Chinese medicine seeds in the feeding bin 201 can fall into the interior of the feeding pipe 103 from the circular opening, and finally fall into the groove opened by the furrow opener 105. This process is repeated. The multiple feeding bins 201 on each turntable 2 are aligned with the circular opening through the rotation amplitude of the turntable 2, and an equal amount of traditional Chinese medicine seeds are put into the groove from the feeding pipe 103. Then, by using the driving wheel 101 to drive the drill seeder body 1 to move forward at a constant speed, an equal amount of traditional Chinese medicine seeds can be evenly put into the groove at equal intervals. In this way, the traditional Chinese medicine seeds can be sown at equal amounts and equal intervals, avoiding the situation of uneven seed density in the groove and inconsistent plant spacing in the groove when using the drill seeding method to sow traditional Chinese medicine seeds, and thus effectively improving the land utilization rate.

[0025] Embodiment 2: Please refer to Figures 8 to 12 and Figure 16As shown in the figure, a lifting mechanism is provided on the drill seeder body 1. The lifting mechanism includes a reciprocating lead screw 3. The reciprocating lead screw 3 is rotatably connected to the inner wall of the drill seeder body 1. The reciprocating lead screw 3 is located directly above the mounting plate 104. A limiting rod 301 is fixedly connected between the opposite faces of the drill seeder body 1. The limiting rod 301 is located directly above the reciprocating lead screw 3. A nut 302 is threadedly connected to the outer surface of the reciprocating lead screw 3. One end of the nut 302 away from the reciprocating lead screw 3 is slidably connected to the outer surface of the limiting rod 301. A roller 303 is rotatably connected to the side of the nut 302 close to the driving wheel 101. A ratchet 304 is fixedly connected to the outer surfaces of the reciprocating lead screw 3 and the transmission rod 2081, and the ratchet teeth of the ratchet 304 on the two are oriented in opposite directions. An installation ring 3041 is rotatably connected to the outer surfaces of the reciprocating lead screw 3 and the transmission rod 2081. A ratchet pawl 3042 is rotatably connected to one side of the installation ring 3041. The front end of the ratchet pawl 3042 in the shape of a claw is engaged with the tooth groove part of the ratchet 304. A first synchronous pulley 3043 is fixedly connected to the outer surface of the installation ring 3041. The outer surfaces of the first synchronous pulleys 3043 are drivingly connected by a first synchronous belt 3044. The output shaft of the servo motor 2083 is fixedly connected to the side of the installation ring 3041 away from the drill seeder body 1.

[0026] Grooves 305 are symmetrically formed in the inner wall of the drill seeder body 1. The mounting plate 104 is slidably connected inside the grooves 305. Support springs 306 are symmetrically and fixedly connected 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. Among them, the top of the lifting plate 307 is inclined, and the vertical height of the lifting plate 307 gradually increases from the side close to the first synchronous belt 3044 to the side away from it. The outer surface of the roller 303 is adapted to the inclined top of the lifting plate 307. Installation grooves 308 are equidistantly formed in the inclined surface of the top of the lifting plate 307. An installation rod 309 is fixedly connected to the bottom of the installation groove 308. A trigger block 310 is slidably connected in the installation groove 308. Among them, the top of the trigger block 310 is in a horizontal state, which is used to provide a retention position for the roller 303 on the inclined surface of the lifting plate 307, so as to facilitate the subsequent equidistant lifting of the furrow opener 105. A return spring 311 is sleeved on the outer surface of the installation rod 309. Both ends of the return spring 311 are fixedly connected to the bottom of the trigger block 310 and the inside of the installation groove 308. A trigger rod 312 is fixedly connected to the bottom of the trigger block 310. A touch switch 313 is fixedly connected to the bottom of the installation groove 308. The touch switch 313 is located on the movement track of the trigger rod 312. Warning lights 314 are equidistantly fixedly connected to the side of the drill seeder body 1 close to the lifting plate 307. The touch switch 313 and the warning lights 314 are electrically connected and controlled by a controller to turn on and off.

[0027] Working process: When it is necessary to adjust the distance between the furrow opener 105 and the field, the seeding operator first starts the servo motor 2083 to rotate it in the reverse direction. The output shaft of the servo motor 2083 drives the mounting ring 3041 on the transmission rod 2081 to rotate in the reverse direction. At this time, the pawl 3042 on the mounting ring 3041 cannot engage with the ratchet 304 on the transmission rod 2081, so that the mounting ring 3041 cannot drive the transmission rod 2081 to rotate synchronously. Therefore, the multiple turntables 2 in the seed box 102 also cannot rotate accordingly. During this process, the mounting ring 3041 drives the first synchronizing wheel 3043 on it to rotate. Then, the first synchronizing wheel 3043 drives the first synchronizing wheel 3043 on the reciprocating lead screw 3 to rotate through the first synchronizing belt 3044 on it, causing the mounting ring 3041 on the reciprocating lead screw 3 to rotate in the same direction. At this time, the pawl 3042 on the mounting ring 3041 engages with the ratchet 304 on the reciprocating lead screw 3, and thus the reciprocating lead screw 3 rotates in the same direction. Then, the reciprocating lead screw 3 drives the nut 302 on it to slide along the outer surface of the limiting rod 301 in the direction away from the first synchronizing wheel 3043, and makes the roller 303 on the nut 302 roll horizontally at a constant speed along the inclined surface at the top of the lifting plate 307. The roller 303 gradually presses the top of the lifting plate 307, rolls from the lowest point of the inclined surface at the top of the lifting plate 307 to a relatively higher position, and moves to the top of the trigger block 310 on it. At this time, the lifting plate 307 is uniformly moved downward by a certain distance under the extrusion of the roller 303. Immediately afterwards, the lifting plate 307 pushes the mounting plate 104 to move vertically downward inside the groove 305, and the mounting plate 104 drives the multiple furrow openers 105 on it to move vertically downward synchronously, and squeezes the support spring 306 inside the groove 305 to contract under force. Thus, the furrow opener 105 can be moved 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 every time the roller 303 rolls to a trigger block 310 at the top of the lifting plate 307, the furrow opener 105 can be moved downward by the same distance. During this process, when the roller 303 rolls from the lowest end at the top of the lifting plate 307 to the trigger block 310 at the top of the lifting plate 307 and from the trigger block 310 at the lower end to the trigger block 310 at the relatively higher end, the roller 303 comes into contact with the trigger block 310 here and squeezes the trigger block 310 to move vertically downward along the outer surface of the mounting rod 309. At this time, the return spring 311 sleeved on the mounting rod 309 here contracts under force, and the trigger rod 312 at the bottom of the trigger block 310 moves downward accordingly and continuously approaches the touch switch 313 in the mounting groove 308 here. Subsequently, the trigger rod 312 squeezes the touch switch 313 to connect the circuit of the warning light 314 electrically connected to it, and turns on the warning light 314 through the controller to remind that the furrow opener 105 has been adjusted to the required position. When the roller 303 disengages from the lower horizontal end at the top of the lifting plate 307,The return spring 311 inside the mounting groove 308 here continuously extends upward due to the loss of the squeezing of the roller 303. The return spring 311 pushes the trigger block 310 to move vertically upward along the outer surface of the mounting rod 309, and causes the trigger rod 312 at the bottom of the trigger block 310 to gradually disengage from the touch switch 313, thereby disconnecting the circuit of the warning light 314 electrically connected thereto, and turning off the warning light 314 through the controller. Thus, the depth of the furrow opener 105 can be adjusted equidistantly by using the lifting plate 307 to move the same distance multiple times, and the sowing personnel can be reminded in time that the furrow opener 105 has been adjusted in place, so as to be suitable for the tillage depth conditions required for sowing different varieties of Chinese medicinal seeds, and the time required for adjustment can be effectively reduced, thereby increasing the effective working time and improving the overall work efficiency. At the same time, the warning light 314 can visually remind the worker of the depth adjusted by the furrow opener 105, and prevent the worker from adjusting too deep or too shallow due to the difficulty in grasping the depth adjustment when manually adjusting. This can not only improve the safety of the working process, but also reduce the workload of the sowing personnel.

[0028] When the roller 303 moves to the highest point of the top inclined surface of the lifting plate 307, the reciprocating screw 3 drives the roller 303 to move in the opposite direction along the top inclined surface of the lifting plate 307 through the nut 302. Similarly, the lifting plate 307 can be moved up the same distance multiple times, thereby adjusting the position of the furrow opener 105 equidistantly upward.

[0029] Example 3: Please refer to Figures 13 to 15 As shown, a uniform soil covering mechanism is provided on the drill body 1, and the uniform soil covering mechanism includes a plurality of equally spaced collecting bins 4, and the openings of the plurality of collecting bins 4 are open, which are used to collect the covering soil opened by the furrow opener 105. The plurality of collecting bins 4 are equally spaced and fixedly connected in the drill body 1, and a connecting rod 401 is rotatably connected between the bottom of the drill body 1, and a first soil turning cylinder 402 and a first gear 403 are equidistantly and fixedly connected to the outer surface of the connecting rod 401 in sequence, and the first soil turning cylinder 402 is located inside the collecting bin 4, and the first gear 403 is located outside the collecting bin 4. A second soil turning cylinder 404 is rotatably connected inside the collecting bin 4, and 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 pressing wheel 106. The rotating shaft of the second soil turning cylinder 404 is fixedly connected to a second gear 405, and the second gear 405 is located outside the collecting bin 4, and the first gear 403 is meshed with the second gear 405. The connecting rod 401 and the outer surface of the rotating shaft of the ground pressing wheel 106 are both fixedly connected with a second synchronous wheel 406 , and the outer surfaces of the second synchronous wheel 406 are connected through a second synchronous belt 407 .

[0030] Working process: When the drill body 1 moves forward at a constant speed, it drives the land roller 106 to roll along the surface of the field in the same direction. When the land roller 106 rolls forward at a constant speed in the same direction as the drill body 1, the collecting bin 4 can guide the soil covering lifted by the furrow opener 105 to its middle part. The second synchronous pulley 406 on the rotating shaft of the land roller 106 also rotates in the same direction. The second synchronous pulley 406 on it drives the second synchronous pulley 406 on the connecting rod 401 to rotate through the synchronous belt two 407 on it. Thus, multiple first soil-turning cylinders 402 on the connecting rod 401 also rotate in the same direction. Thereby, multiple first soil-turning cylinders 402 can turn the soil covering lifted by the furrow opener 105 obliquely upward into the inside of the collecting bin 4. At the same time, multiple first gears 403 located on the connecting rod 401 also rotate in the same direction. Then, the first gear 403 drives the second gear 405 meshing with it to rotate, and makes the second gear 405 rotate in the opposite direction to the first gear 403. Immediately, the second gear 405 drives the second soil-turning cylinder 404 to rotate in the same direction. Thus, the first soil-turning cylinder 402 and the second soil-turning cylinder 404 rotate relative to each other, and use the bumps on both of them to turn, extrude and crush the caked soil blocks in the soil covering. Thereby, the soil covering on the traditional Chinese medicine seeds can have smaller particles, and further, it can avoid the caked soil blocks in the soil covering from squeezing the traditional Chinese medicine seeds and preventing them from germinating and growing effectively. It can also avoid the soil covering on the traditional Chinese medicine seeds being too deep and affecting the respiration and germination of the traditional Chinese medicine seeds. Furthermore, it can improve the germination rate of the traditional Chinese medicine seeds and the uniformity of seedling emergence. At the same time, by jointly turning the soil covering by the first soil-turning cylinder 402 and the second soil-turning cylinder 404, the soil covering can be evenly covered on each traditional Chinese medicine seed. Furthermore, it can improve the air permeability and water permeability of the soil, so that the traditional Chinese medicine seeds can obtain sufficient oxygen and water during the germination process, thereby effectively improving the germination rate of the traditional Chinese medicine seeds.

[0031] After the fine soil covering on the traditional Chinese medicine seeds is completed, the uniformly rolling land roller 106 presses the extruded and crushed soil covering downward, and gently compresses the soil covering by the own weight of the land roller 106 to make the soil covering closely combine with the seeds, thus becoming the sowing work of the traditional Chinese medicine seeds.

[0032] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
