Description

Technical Field

[0001] This utility model relates to the field of seeding technology, and more specifically to a high-efficiency seeding machine for organic Tibetan medicine cultivation. Background Technology

[0002] In the cultivation of organic Tibetan medicinal herbs, the sowing process is crucial. In actual sowing operations, traditional seeders often cannot maintain a uniform speed. For example, in complex terrain conditions such as mountains and slopes, the speed of the seeder will vary due to factors such as terrain undulations and differences in soil texture. Or, during long-term operation, mechanical failures and operator habits can also lead to unstable speeds. When the seeder is in a non-uniform speed operation state, the uniformity and stability of sowing become even more difficult to guarantee. This makes the distribution of seeds in the soil more chaotic and disorderly, further exacerbating the problem of uneven seed distribution. This seriously limits the efficiency and quality of organic Tibetan medicinal herb cultivation and poses a great obstacle to the large-scale and efficient cultivation of organic Tibetan medicinal herbs.

[0003] A search revealed that utility model patent CN205658002U discloses a seeder for organic Tibetan medicinal herb cultivation. The seeder comprises: a combined support frame with a left insertion port on the left side and a right insertion port on the right side. Both the left and right insertion ports are connected to combined inserts, which are respectively connected to a left support plate and a right support plate. The front ends of both the left and right support plates have front slots connected to a front support plate. The rear ends of both the left and right support plates have rear slots connected to a rear support plate. The left, right, front, and rear support plates are all connected to an organic Tibetan medicinal herb seeding box. The seeding box is connected to a seeding tube, which is attached to a plowshare column. The plowshare column is connected to a plowshare and is connected to a left and right arc-shaped baffle. The seeding tube is located between the left and right arc-shaped baffles.

[0004] In this patent, the seeding tube is directly connected to the seeding box. When the device moves, the seeds slide continuously from the seeding box to the ground through the seeding tube. As a result, there are no gaps between the seeds, which leads to an overly dense distribution of seeds in the seeding area. During the germination and growth process, the plants will have insufficient space, their root systems will be restricted, and they will be unable to fully absorb nutrients and water from the soil. The leaves will also block each other, affecting photosynthesis, resulting in poor plant growth. Weak plants may even die because they cannot compete with the surrounding plants, ultimately reducing the yield and quality of Tibetan medicine. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-efficiency seeder for organic Tibetan medicine cultivation, so as to solve the problems existing in the background art.

[0006] The utility model provides the following technical solution: a high-efficiency organic Tibetan medicine planter, including a planter body and guide pipes equidistantly installed on the planter body. A connecting pipe is fixedly connected to the end face of the guide pipe. An annular airbag is fixedly installed inside the connecting pipe. A fixing seat is fixedly sleeved on the outer surface of the connecting pipe. A material blocking component is installed inside the fixing seat. A rotating wheel is fixedly connected to the input end of the material blocking component. The output end of the material blocking component is connected to the inside of the annular airbag.

[0007] Furthermore, the material-blocking assembly includes a circular groove formed inside the fixed base, a sealing disc slidably connected inside the circular groove, a sliding groove formed at the center of the side of the sealing disc, a connecting pipe fixedly connected inside the fixed base, the interior of the circular groove communicating with the interior of the annular airbag through the connecting pipe, a positioning rod fixedly connected to the inner wall of the sliding groove, a bearing fixedly installed inside the fixed base, a rotating shaft fixedly connected to the inner ring of the bearing, a reciprocating screw fixedly connected to one end of the rotating shaft, and the other end of the rotating shaft fixedly connected to the center of the surface of the rotating wheel, the outer surface of the positioning rod inserted into the threaded groove of the reciprocating screw, a limit groove formed inside the sealing disc, a limit rod inserted inside the limit groove, and the end face of the limit rod fixedly connected to the inner wall of the circular groove.

[0008] Furthermore, a feed trough is provided through the interior of the connecting pipe, the top diameter of the feed trough is larger than the bottom diameter, the interior of the guide pipe is connected to the interior of the feed trough, and the inner wall of the annular airbag extends into the interior of the feed trough.

[0009] Furthermore, the outer surface of the reciprocating screw is inserted into the interior of the slide groove, the reciprocating screw is rotatably connected to the center of the interior of the slide groove, and the diameter of the end of the limiting bar away from the bearing is larger than the diameter of the other end.

[0010] Furthermore, a sealing ring is fixedly fitted onto the surface of the sealing disc, and the end of the rotating shaft away from the reciprocating screw extends to the outside of the fixed seat.

[0011] Furthermore, the end of the circular groove near the connecting pipe is sealed, and the surface of the annular airbag near the inner wall of the connecting pipe is arc-shaped.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. The design of the material blocking component and the annular airbag in this utility model enables precise fixed-distance sowing. During the movement of the seeder body, the rotating wheel drives the rotating shaft and reciprocating screw to rotate, which in turn causes the sealing disc to slide left and right in the circular groove. When the sealing disc slides to the left, a negative pressure is formed inside the annular airbag, the feed chute is connected, and the seeds fall and are sown normally. When the sealing disc slides to the right, the annular airbag is pressurized and expanded to seal the feed chute. Even if the seeder body does not move at a uniform speed, this method can ensure that the sowing distance is relatively fixed each time, so that the Tibetan medicinal seeds are evenly distributed in the soil, providing good growth space for Tibetan medicinal plants, avoiding the problems of nutrient competition and waste of land resources caused by uneven seed distribution, and effectively improving land utilization and Tibetan medicinal yield.

[0014] 2. In this utility model, the annular airbag is made of elastic material. Even if it comes into contact with the seeds when the feeding trough is closed, it will not damage the seeds, greatly reducing the risk of seed damage and better maintaining the integrity of the seeds. This improves the germination rate, reduces the reseeding work caused by seed damage, and saves manpower and material costs. It provides a reliable guarantee for the cultivation of organic Tibetan medicine. At the same time, this design also helps to improve the overall quality of Tibetan medicine cultivation, ensure the quality and efficacy of Tibetan medicine, and promote the healthy development of the organic Tibetan medicine industry.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] A high-efficiency organic Tibetan medicine planter includes a planter body 1 and a guide pipe 2 equidistantly installed on the planter body 1. A connecting pipe 3 is fixedly connected to the end face of the guide pipe 2. An annular airbag 4 is fixedly installed inside the connecting pipe 3. A fixing seat 5 is fixedly sleeved on the outer surface of the connecting pipe 3. A material blocking component 6 is installed inside the fixing seat 5. A rotating wheel 7 is fixedly connected to the input end of the material blocking component 6. The output end of the material blocking component 6 is connected to the inside of the annular airbag 4.

[0023] In this embodiment, the annular airbag 4 inside the connecting pipe 3 cooperates with the material blocking component 6 inside the fixed base 5. The state of the annular airbag 4 is controlled by the rotating wheel 7 driving the material blocking component 6, thereby achieving precise control of seed discharge, laying the foundation for subsequent precise sowing, ensuring orderly sowing, and improving sowing efficiency.

[0024] Specifically, the material blocking assembly 6 includes a circular groove 61 formed inside the fixed base 5. A sealing disc 62 is slidably connected inside the circular groove 61. A sliding groove 63 is formed at the center of the side of the sealing disc 62. A connecting pipe 64 is fixedly connected inside the fixed base 5. The inside of the circular groove 61 is connected to the inside of the annular airbag 4 through the connecting pipe 64. A positioning rod 65 is fixedly connected to the inner wall of the sliding groove 63. A bearing 67 is fixedly installed inside the fixed base 5. A rotating shaft 68 is fixedly connected to the inner ring of the bearing 67. A reciprocating screw 66 is fixedly connected to one end of the rotating shaft 68. The other end of the rotating shaft 68 is fixedly connected to the center of the surface of the rotating wheel 7. The outer surface of the positioning rod 65 is inserted into the threaded groove of the reciprocating screw 66. A limiting groove 69 is formed inside the sealing disc 62. A limiting rod 610 is inserted inside the limiting groove 69. The end face of the limiting rod 610 is fixedly connected to the inner wall of the circular groove 61.

[0025] In this embodiment, when the rotating wheel 7 rotates, it drives the rotating shaft 68 and the reciprocating screw 66 to rotate. The positioning rod 65 cooperates with the reciprocating screw 66 to make the sealing disc 62 slide stably left and right in the circular groove 61. The limiting groove 69 and the limiting rod 610 ensure the accuracy of the sliding direction of the sealing disc 62 and prevent it from shaking or deviating. Through this structure, the pressure change in the circular groove 61 can be precisely controlled, thereby adjusting the inflation and deflation state of the annular airbag 4, realizing precise control of the opening and closing of the feeding trough 31, and ultimately achieving the purpose of precisely controlling the seed sowing interval to ensure that the Tibetan medicine seeds are evenly distributed in the soil.

[0026] Specifically, a feed trough 31 is provided through the inside of the connecting pipe 3. The top diameter of the feed trough 31 is larger than the bottom diameter. The inside of the guide pipe 2 is connected to the inside of the feed trough 31. The inner wall of the annular airbag 4 extends into the inside of the feed trough 31.

[0027] In this embodiment, the top-large and bottom-small design of the feeding trough 31 facilitates the natural falling of seeds under gravity and their accumulation at the smaller diameter opening, making it easier to discharge the seeds in a concentrated manner. The guide pipe 2 is connected to the feeding trough 31 to ensure that the seeds can smoothly enter the feeding trough 31. The inner wall of the annular airbag 4 extends into the feeding trough 31. When the annular airbag 4 expands, it can effectively seal the feeding trough 31 to prevent the seeds from falling when sowing is not required. When the annular airbag 4 contracts, the feeding trough 31 is unobstructed, and the seeds can fall smoothly for sowing, ensuring the controllability of the sowing process.

[0028] Specifically, the outer surface of the reciprocating screw 66 is inserted into the interior of the slide groove 63, and the reciprocating screw 66 is rotatably connected to the center of the interior of the slide groove 63. The diameter of the end of the limit bar 610 away from the bearing 67 is larger than the diameter of the other end.

[0029] In this embodiment, the reciprocating screw 66 is inserted into the slide groove 63 and rotatably connected in its middle, making the sliding of the sealing disc 62 smoother and reducing jamming, ensuring the stable operation of the material blocking component 6. The limiting rod 610 has a larger diameter at one end, which can effectively limit the sliding range of the sealing disc 62 in the circular groove 61, preventing the sealing disc 62 from sliding excessively and affecting the normal operation of the annular airbag 4, thus ensuring the reliability and stability of the entire sowing control process.

[0030] Specifically, a sealing ring is fixedly fitted onto the surface of the sealing disc 62, and the end of the rotating shaft 68 away from the reciprocating screw 66 extends to the outside of the fixed seat 5.

[0031] In this embodiment, the sealing ring on the surface of the sealing disc 62 enhances the sealing performance of the circular groove 61, ensuring that the gas in the circular groove 61 will not leak during the sliding process of the sealing disc 62, thus ensuring the accuracy of pressure changes and precisely controlling the state of the annular airbag 4. One end of the rotating shaft 68 extends to the outside of the fixed base 5, which facilitates connection with the rotating wheel 7, allowing the rotating wheel 7 to drive the rotating shaft 68 and the entire material blocking assembly 6 to work, so that the seeder can automatically control the sowing action during movement, improving the automation level of the sowing operation.

[0032] Specifically, the end of the circular groove 61 near the connecting pipe 64 is sealed, and the surface of the annular airbag 4 near the inner wall of the connecting pipe 3 is arc-shaped.

[0033] In this embodiment, the end of the circular groove 61 near the connecting pipe 64 is sealed to ensure stable pressure inside the circular groove 61, prevent gas leakage from affecting the normal inflation and deflation of the annular airbag 4, and ensure the accuracy of seeding control. The surface of the annular airbag 4 near the inner wall of the connecting pipe 3 is arc-shaped. This design allows it to fit more tightly with the inner wall of the feeding groove 31 when it expands and closes the feeding groove 31, resulting in a better sealing effect. At the same time, the arc-shaped structure can reduce the squeezing and damage to the seeds when in contact with them, protecting the integrity of the seeds.

[0034] The working principle and usage process of this utility model are as follows: During use, after placing the seeds in the seed box on the main body 1 of the seeder, they enter the connecting pipe 3 through the guide pipe 2. The movement of the main body 1 of the seeder causes the rotating wheel 7 to rotate on the ground. When the rotating wheel 7 rotates, it drives the reciprocating screw 66 to rotate through the rotating shaft 68. Through the engagement of the reciprocating screw 66 with the positioning rod 65, the sealing disc 62 slides left and right inside the circular groove 61. When the sealing disc 62 slides to the left, the right end of the circular groove 61 is under negative pressure, and this negative pressure is transmitted through the connecting pipe. The tube 64 creates a negative pressure inside the annular airbag 4, while the inside of the feed trough 31 is in a connected state, allowing seeds to fall directly onto the ground through the feed trough 31. When the sealing disc 62 slides to the right, the inside of the annular airbag 4 is pressurized. Through the expansion of the annular airbag 4, the inside of the feed trough 31 is sealed, ensuring that even when the seeder body 1 is moving at a non-uniform speed, a certain distance can still be maintained for sowing, thus improving sowing efficiency. Moreover, due to the elasticity of the annular airbag 4, even when it comes into contact with the seeds while sealed, it will not damage the seeds.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
