DETAILED DESCRIPTION

[0019] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a technical solution: referring to Figure 1 - Fig.10The present invention discloses an efficient sowing device for planting Chinese medicinal materials, comprising a plurality of fixed plates 1, on which a sowing assembly 2 is provided, wherein the sowing assembly 2 comprises a rotating disk 22, wherein a storage groove 21 is provided in the fixed plate 1, wherein the rotating disk 22 is provided in the storage groove 21 and is connected to the inner wall of the storage groove 21, wherein both driving ends of the rotating disk 22 extend to the outside of the corresponding fixed plate 1 and are rotatably connected to the corresponding fixed plate 1 through a bearing, wherein an annular groove 23 is provided at the middle position of the outer peripheral wall of the rotating disk 22, wherein a soft pad 24 is fixedly installed in the annular groove 23, and the outer peripheral wall of the soft pad 24 is in contact with the inner wall of the storage groove 21, wherein a plurality of circular grooves 25 are provided on the outer peripheral wall of the soft pad 24 and in the corresponding rotating disk 22 in a circular array, and the cross-section of each circular groove 25 is in a T-shaped arrangement, wherein a piston plate 26 is slidably installed in the circular groove 25, and a circular hole 27 is provided at the position corresponding to the circular groove 25 on the bottom side of the fixed plate 1; Several fixed plates 1 are connected by a connecting assembly 4, and a supporting mechanism 3 is provided on the front and rear sides of the fixed plate 1. A feeding mechanism 5 is provided at the middle position of the top side of the fixed plate 1, and a liquid injection mechanism 6 is provided at the right end of the top side of the fixed plate 1.

[0021] In this embodiment, when the improved efficient sowing device for Chinese medicinal plant planting is used, the operator can adjust the sowing row spacing between the Chinese medicinal plant seeds by disassembling and assembling the connecting mechanism and the fixed plate 1, and then put an appropriate amount of different Chinese medicinal plant seeds or the same Chinese medicinal plant seeds into a plurality of storage mechanisms, and inject different nutrient solutions or the same nutrient solutions into the injection mechanism 6, so that the device can perform sowing operations of different Chinese medicinal plants or the same Chinese medicinal plant seeds; After the adjustment of the above-mentioned device and the loading operation of the raw materials are completed, the operator completes the connection between the traction mechanism and the device through the connecting mechanism, and then the pulling device is located on the planting ground to move in a linear trajectory through the traction mechanism. Due to the support of the fixed plate 1 by the supporting mechanism 3, the fixed plate 1 is synchronously located at a specific height on the planting ground to move in a linear trajectory. At the same time, the supporting mechanism 3 drives the turntable 22 to rotate at a corresponding rate according to the sowing requirements of the Chinese medicine seeds. The rotating turntable 22 drives the circular groove 25 to align with the unloading mechanism 5 and the injection mechanism 6 in turn. When the circular groove 25 is aligned with the unloading mechanism 5, the Chinese medicine seeds in the unloading mechanism 5 fall into the circular groove 25. At this time, due to the mutual interference between the Chinese medicine seeds and the piston plate 26, and the Chinese medicine seeds in the circular groove 25 and the discharge port of the storage hopper 51 The mutual interference of the Chinese medicine seeds ultimately makes it so that when the circular groove 25 is aligned with the storage hopper 51, only one Chinese medicine seed falls into the circular hole 27. When the circular hole 27 is aligned with the injection mechanism 6, the nutrient solution in the injection mechanism 6 is injected into the circular hole 27. Due to the push of the nutrient solution on the piston plate 26, the piston plate 26 moves a corresponding distance into the circular groove 25 according to the sowing requirements of the Chinese medicine seeds, so that a corresponding amount of nutrient solution is stored in the circular groove 25. Finally, when the circular groove 25 is aligned with the circular hole 27, due to the push of the gas in the circular groove 25 on the piston plate 26, the piston plate 26 quickly moves and resets, so that the nutrient solution and Chinese medicine seeds in the circular groove 25 are quickly pushed out of the circular hole 27 through the piston plate 26, so that the nutrient solution and Chinese medicine seeds directly fall into the groove on the planting ground. It should be noted that the space between the piston plate 26 and the bottom of the corresponding circular groove 25 is filled with high-pressure air, and a control panel is fixedly mounted on the outer peripheral wall of the storage hopper 51 to control the operating status of the device.

[0022] In a further preferred embodiment of the present invention, Figure 3 As shown, the support mechanism 3 includes a plurality of rollers 31, the axles of the rollers 31 are inserted into corresponding mounting grooves of the fixing plate 1 and are rotatably connected to the fixing plate 1, and the bottom ends of the rollers 31 are located below the fixing plate 1; In this embodiment, when the pulling device of the traction equipment is moving on the planting ground, due to the friction between the roller 31 and the ground, the roller 31 rolls synchronously on the planting ground as the fixed plate 1 moves, and due to the support of the fixed plate 1 by the roller 31, the fixed plate 1 is always located at a specific position above the ground.

[0023] In a further preferred embodiment of the present invention, Figure 3 and Figure 4As shown, transmission gears 32 are fixedly mounted on the front and rear driving ends of the turntable 22, and two electronically controlled gear transmissions 33 are relatively fixedly mounted at the positions corresponding to the transmission gears 32 on the front and rear sides of the fixed plate 1, and the axle of the left end roller 31 is fixedly passed through the gear ring at the input end of the electronically controlled gear transmission 33, and the output gear of the electronically controlled gear transmission 33 is meshed and connected with the corresponding transmission gear 32; In this embodiment, the roller 31 can synchronously drive the electronically controlled gear transmission 33 to run synchronously while rolling on the planting ground, and drive the transmission gear 32 to rotate through the electronically controlled gear transmission 33, and synchronously drive the turntable 22 to rotate, and by adjusting the electronically controlled gear transmission rate, the turntable 22 can be adjusted at a corresponding rate according to the type of Chinese medicinal seeds, so that the spacing between the seeds can be adjusted to a suitable length during sowing; It should be noted that the above-mentioned electronically controlled gear transmission 33 is mainly composed of a housing, a gear ring, a plurality of gears and an electronically controlled adjustment mechanism, so as to adjust the transmission ratio between the roller 31 and the turntable 22 through the meshing of gears with different diameters.

[0024] In a further preferred embodiment of the present invention, Figure 3 and Figure 6 As shown, a plow blade 7 is provided on the left side of the fixed plate 1, and the plow blade 7 is fixedly connected to the corresponding fixed plate 1 by bolts, and the bottom end of the plow blade 7 is located below the roller 31, and a scraper 8 with a V-shaped top view is provided on the right side of the fixed plate 1, and the scraper 8 is fixedly connected to the corresponding fixed plate 1 by a connecting rod, and the bottom side of the scraper 8 is coplanar with the bottom end of the corresponding roller 31; In this embodiment, when the above device is used, the operator unscrews the bolts on the plow blade 7, and then adjusts the height of the bottom end of the plow blade 7 below the fixed plate 1 according to the sowing requirements, and the furrowing depth of the plow blade 7 is adjusted; During the movement of the fixed plate 1, the plow blades 7 can be used to open grooves in advance on the planting ground for sowing the Chinese medicinal seeds before the Chinese medicinal seeds fall through the circular holes 27. After the Chinese medicinal seeds fall into the grooves, the fixed plate 1 pulls the scraper 8, and the bottom side of the scraper 8 slides against the ground. When the scraper 8 moves to the position of the soil on both sides of the groove, the soil can be scraped into the groove along the inner slope of the scraper 8 due to the mutual interference between the soil and the inner slope of the scraper 8, and the soil on both sides of the groove is automatically backfilled, which simplifies the sowing operation of the Chinese medicinal seeds and reduces the operator's workload.

[0025] In a further preferred embodiment of the present invention, Figure 1 and Figure 2As shown, the connection assembly 4 includes a connection plate 41, the cross-section of the connection plate 41 is L-shaped, and the corners of the connection plate 41 are arc-shaped. A plurality of mounting holes 42 are provided on the top side of the connection plate 41 and the left side of the connection plate 41, and the spacing between two adjacent mounting holes 42 is equal. The connection plate 41 is fixedly connected to the fixing plate 1 by bolts, and the spacing between two adjacent fixing plates 1 is equal. A mounting plate 43 is fixedly installed at the middle position of the outer arc wall of the connection plate 41; In this embodiment, before using the above-mentioned device, the operator unscrews the bolts on the connecting plate 41 to complete the separation between the connecting plate 41 and the fixed plate 1, and then adjusts the spacing between several fixed plates 1 according to the sowing needs of traditional Chinese medicine seeds, and finally uses bolts to re-complete the fixation between the connecting plate 41 and the fixed plate 1. The spacing adjustment between the grooves is completed, and the device can be installed at the tail end of the traction equipment through the mounting plate 43, so that the device can be pulled by the traction equipment to reduce the operator's work intensity when sowing traditional Chinese medicine seeds.

[0026] In a further preferred embodiment of the present invention, Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the unloading mechanism 5 includes a storage hopper 51, which is arranged at the middle position of the top side of the corresponding fixed plate 1, and the discharge end of the storage hopper 51 is inserted into the storage tank 21 and fixedly connected to the corresponding fixed plate 1, and the discharge end of the storage hopper 51 is connected to the outer peripheral wall of the corresponding soft pad 24, and the top opening of the storage hopper 51 is internally threaded with a cylinder cover 52, and the center position of the cylinder cover 52 is fixedly penetrated with a filter plate 53; In this embodiment, during the use of the above-mentioned device, the operator unscrews the cylinder cover 52 from the storage hopper 51, and then pours an appropriate amount of different Chinese medicinal seeds or the same Chinese medicinal seeds into the storage hopper 51. The Chinese medicinal seeds poured into the storage hopper 51 slide along the inner wall of the storage hopper 51 and fall into the discharge port of the storage hopper 51, so that an appropriate amount of Chinese medicinal seeds are arranged in sequence from top to bottom in the discharge port of the storage hopper 51 until the discharge port of the storage hopper 51 is filled with Chinese medicinal seeds. Subsequent Chinese medicinal seeds are stored in the storage hopper 51, and finally the sealing cover is screwed back into the top opening of the storage hopper 51, and the loading of Chinese medicinal seeds is completed, so that different storage hoppers 51 can synchronously complete the storage of different Chinese medicinal seeds.

[0027] In a further preferred embodiment of the present invention, Figure 3 , Figure 5 , Figure 6 and Fig.10As shown, the liquid injection mechanism 6 includes a liquid storage cylinder 61, which is fixedly installed at the right end of the top side of the corresponding fixed plate 1, and a piston push plate 62 is slidably installed in the liquid storage cylinder 61. A guide tube 63 is provided at the middle position on the right side of the fixed plate 1, and one end of the guide tube 63 is inserted into the corresponding storage groove 21 and fixedly connected to the corresponding fixed plate 1. One end of the guide tube 63 contacts the outer peripheral wall of the corresponding soft pad 24, and an electric control valve 64 is fixedly installed and penetrated on the outer peripheral wall of the bottom of the liquid storage cylinder 61, and the other end of the guide tube 63 is threadedly sleeved on the discharge end of the corresponding electric control valve 64; In this embodiment, during the rotation of the turntable 22, when the circular hole 27 is aligned with the conduit 63, part of the nutrient solution in the liquid storage cylinder 61 flows into the circular groove 25 through the conduit 63, so that when the Chinese medicine seeds fall into the groove, the nutrient solution can be simultaneously sprinkled on the soil near the Chinese medicine seeds, so that the device can simultaneously complete the sowing of the Chinese medicine seeds and the spraying of the nutrient solution.

[0028] In a further preferred embodiment of the present invention, Figure 5 and Fig.10 As shown, an air pump 65 is provided above the piston push plate 62, and the air inlet end of the air pump 65 is fixedly penetrated through the wall of the corresponding liquid storage cylinder 61, and a plurality of exhaust ports 66 are fixedly penetrated and installed in a circular array on the outer peripheral wall of the top of the liquid storage cylinder 61, and each exhaust port 66 is located above the corresponding piston push plate 62; In this embodiment, when the above-mentioned device is performing the sowing operation of Chinese medicinal seeds, the air pump 65 is simultaneously started to continuously extract external gas and inject it into the liquid storage cylinder 61. At this time, due to the limited amount of gas discharged from the exhaust interface 66, a relatively stable negative pressure cavity is formed at the top of the liquid storage cylinder 61, thereby applying a relatively stable thrust to the nutrient solution in the liquid storage cylinder 61 and the conduit 63. The strength of the high-pressure cavity at the top of the liquid storage cylinder 61 can be adjusted by adjusting the gas injection rate of the air pump 65, and the size of the high-pressure cavity at the top of the liquid storage cylinder 61 can be adjusted by adjusting the gas injection rate of the air pump 65. When the above-mentioned nutrient solution flows into the circular groove 25, the high-pressure chamber at the top of the liquid storage cylinder 61 applies a thrust to the piston push plate 62 through the nutrient solution, so that the piston push plate 62 slides a corresponding distance into the piston plate 26 to compress the air in the circular groove 25. The storage amount of nutrient solution in the circular groove 25 can be adjusted by adjusting the pressure of the high-pressure chamber at the top of the liquid storage cylinder 61 to cope with seeds of different types of Chinese medicinal plants.

[0029] In a further preferred embodiment of the present invention, Figure 5 , Figure 6 and Figure 8As shown, a plurality of L-shaped air injection holes 54 are provided on the outer peripheral wall of the soft pad 24 and in the rotating disk 22 in a circular array, and each air injection hole 54 is located on the outer peripheral side of the corresponding circular hole 27, and the interior of the air injection hole 54 is communicated with the interior of the corresponding circular hole 27. An air guide tube 55 is provided at the position of the circular hole 27 on the top side of the fixed plate 1, and the bottom end of the air guide tube 55 is inserted into the corresponding storage groove 21 and contacts the outer peripheral wall of the corresponding soft pad 24, and the top end of the air guide tube 55 is connected and installed with the exhaust end of the corresponding exhaust interface 66; In the present embodiment, after the circular hole 27 is aligned with the discharge port of the storage hopper 51, part of the excess gas at the top of the liquid storage cylinder 61 flows into the air duct 55 through the exhaust interface 66, and then is introduced into the circular hole 27 through the air duct 55. The airflow flowing into the circular hole 27 flows into the storage hopper 51 from the discharge hopper of the storage hopper 51, and then flows into the storage hopper 51 through the holes of the filter plate 53, so that an airflow from bottom to top is formed in the storage hopper 51. The airflow can exert an upward thrust on the Chinese medicinal seeds, thereby breaking the equilibrium state of the Chinese medicinal seeds stuck in the storage hopper 51, so that the Chinese medicinal seeds in the storage hopper 51 can fall normally, so as to avoid the situation where the Chinese medicinal seeds in the storage hopper 51 are stuck and cannot fall.

[0030] In a further preferred embodiment of the present invention, Figure 5 and Fig.10 As shown, a guide rod 56 is slidably installed at the center of the filter plate 53, a circular plate 57 is fixedly installed at the top of the guide rod 56, and the diameter of the circular plate 57 is smaller than the diameter of the filter plate 53, and a spring 58 is spirally wound on the outer circumference of the guide rod 56, and the two ends of the spring 58 are respectively fixedly connected to the bottom side of the corresponding filter plate 53 and the corresponding guide rod 56; In this embodiment, the airflow discharged from the hole of the filter plate 53 can apply an upward thrust to the guide rod 56 through the circular plate 57, so that the guide rod 56 moves upward to compress the spring 58 until the thrust of the spring 58 on the guide rod 56 is equal to the thrust of the airflow on the circular plate 57. After the circular hole 27 is misaligned with the discharge port of the storage hopper 51, due to the fit between the soft pad 24 and the bottom end of the air guide pipe 55, the gas in the liquid storage cylinder 61 will not continue to flow into the storage hopper 51. At this time, the circular plate 57 Without the thrust exerted by the airflow, due to the push of the spring 58 on the guide rod 56, the guide rod 56 pulls the circular plate 57 to move rapidly toward the filter plate 53, causing a strong collision between the circular plate 57 and the filter plate 53, and then causing the storage hopper 51 to vibrate to a certain extent, thereby breaking the equilibrium state of the Chinese medicinal seeds stuck in the storage hopper 51, allowing the Chinese medicinal seeds in the storage hopper 51 to fall normally, thereby avoiding the situation where the Chinese medicinal seeds in the storage hopper 51 are stuck and cannot fall.

[0031] Working principle: When the improved high-efficiency sowing device for Chinese medicinal plant planting is used, the operator first screws the barrel cover 52 out of the storage hopper 51, and then pours an appropriate amount of different Chinese medicinal seeds or the same Chinese medicinal seeds into the storage hopper 51. The Chinese medicinal seeds poured into the storage hopper 51 slide along the inner wall of the storage hopper 51 and fall into the discharge port of the storage hopper 51, so that an appropriate amount of Chinese medicinal seeds are arranged in sequence from top to bottom in the discharge port of the storage hopper 51 until the discharge port of the storage hopper 51 is filled with Chinese medicinal seeds, and subsequent Chinese medicinal seeds are stored in the storage hopper 51. Finally, the cover is screwed back into the top opening of the storage hopper 51, and the feeding of Chinese medicinal seeds is completed; After the loading of the Chinese medicinal seeds is completed, the operator twists the top end of the conduit 63 out of the discharge end of the electric control valve 64, and then connects the discharge end of the nutrient solution injection device and the discharge end of the electric control valve 64 through a water pipe. The electric control valve 64 is opened, and the nutrient solution injection device injects the nutrient solution required for the planting of Chinese medicinal seeds into the liquid storage cylinder 61 to complete the loading process of the nutrient solution. According to the sowing requirements of the Chinese medicinal seeds in the storage hopper 51, the corresponding types of nutrient solutions can be injected into different liquid storage cylinders 61 respectively; After the above-mentioned Chinese medicinal seeds are loaded, the operator unscrews the bolts on the plow blade 7, and then adjusts the height of the bottom end of the plow blade 7 below the fixed plate 1 according to the sowing requirements, and the furrowing depth of the plow blade 7 is adjusted; After the position adjustment of the plow blade 7 is completed, the operator unscrews the bolts on the connecting plate 41 to complete the separation between the connecting plate 41 and the fixing plate 1, and then adjusts the spacing between the fixing plates 1 according to the sowing needs of the Chinese medicinal seeds, and finally uses the bolts to re-fix the connecting plate 41 and the fixing plate 1, and the spacing adjustment between the furrows is completed; After the adjustment of the above device is completed, the operator installs the device at the tail end of the traction device through the mounting plate 43, and then the operator pulls the device to move on the planting ground through the traction mechanism, and as the moving plow blade 7 of the fixed plate 1 is inserted into the planting ground, a groove of a suitable depth is opened on the planting ground, and then when the scraper 8 moves to the position of the soil on both sides of the groove, due to the mutual interference between the soil and the inner inclined surface of the scraper 8, the soil can be scraped into the groove along the inner inclined surface of the scraper 8, completing the backfilling of the soil on both sides of the groove; During the movement of the above-mentioned device, due to the pulling of the connecting plate 41 on the fixed plate 1, several fixed plates 1 are synchronously moved along with the traction equipment. At this time, due to the friction between the roller 31 and the ground, the roller 31 is synchronously located on the ground and rolls. The rotating roller 31 synchronously drives the transmission gear 32 to rotate at a corresponding speed through the electronically controlled gear transmission 33, and synchronously drives the turntable 22 to rotate at a specific speed according to the planting requirements of the Chinese medicine seeds. During the rotation of the turntable 22, the circular groove 25 is aligned with the discharge port of the storage hopper 51 in turn, so that the Chinese medicine seeds in the discharge port of the storage hopper 51 fall into the discharge hole for storage. At this time, due to the mutual conflict between the Chinese medicine seeds and the piston plate 26, and the mutual conflict between the Chinese medicine seeds in the circular groove 25 and the Chinese medicine seeds in the discharge port of the storage hopper 51, finally when the circular groove 25 is aligned with the storage hopper 51, only one Chinese medicine seed will fall into the circular hole 27, and then with the rotation of the turntable 22, the Chinese medicine seeds in the circular groove 25 move along a fixed trajectory; During the rotation of the above-mentioned disc, the air pump 65 is synchronously started to continuously extract external gas and inject it into the liquid storage cylinder 61. At this time, due to the limited amount of gas discharged from the exhaust interface 66, a relatively stable negative pressure cavity is formed at the top of the liquid storage cylinder 61, thereby applying a relatively stable thrust to the nutrient solution in the liquid storage cylinder 61 and the conduit 63. The strength of the high-pressure cavity at the top of the liquid storage cylinder 61 can be adjusted by adjusting the gas injection rate of the air pump 65; When the turntable 22 drives the Chinese medicinal seeds to the position of the conduit 63, the circular hole 27 at this position is connected to the conduit 63, and the nutrient solution in the conduit 63 flows into the circular groove 25. At this time, the top high-pressure chamber in the liquid storage cylinder 61 applies a thrust to the piston push plate 62 through the nutrient solution, so that the piston push plate 62 slides into the piston plate 26 by a corresponding distance to compress the air in the circular groove 25, so that the corresponding amount of nutrient solution is stored in the circular groove 25. Subsequently, the circular groove 25 is misaligned with the conduit 63. Due to the soft plate and the storage groove 2 1, a closed space is formed in the circular groove 25 for storing the nutrient solution. Then, as the turntable 22 rotates, the circular groove 25 continues to move toward the circular hole 27 with the Chinese medicine seeds and a certain amount of nutrient solution. When the Chinese medicine seeds move to the position of the circular hole 27, the piston push plate 62 is pushed by the gas in the circular groove 25, and the piston push plate 62 is quickly reset, thereby pushing out the Chinese medicine seeds and nutrient solution in the circular groove 25, and making the nutrient solution and Chinese medicine seeds fall into the groove, completing the operation of filling the Chinese medicine seeds in the groove; It should be noted that, according to the above, the operator separates the fixed plate 1 from the plow blade 7 and the scraper 8, and then fills the nutrient solution according to the above, and can specifically spray the nutrient solution on the soil around the seeds; After the circular hole 27 is aligned with the discharge port of the storage hopper 51, part of the excess gas at the top of the liquid storage cylinder 61 flows into the air guide pipe 55 through the exhaust interface 66, and then is introduced into the circular hole 27 through the air guide pipe 55. The airflow flowing into the circular hole 27 flows into the storage hopper 51 from the discharge hopper of the storage hopper 51, and then flows into the storage hopper 51 through the holes of the filter plate 53, so that an airflow from bottom to top is formed in the storage hopper 51. The airflow can exert an upward thrust on the Chinese medicine seeds, thereby breaking the equilibrium state of the Chinese medicine seeds stuck in the storage hopper 51, so that the Chinese medicine seeds in the storage hopper 51 can fall normally, so as to avoid the situation where the Chinese medicine seeds in the storage hopper 51 are stuck and cannot fall; The airflow discharged from the hole of the filter plate 53 can apply an upward thrust to the guide rod 56 through the circular plate 57, so that the guide rod 56 moves up to compress the spring 58 until the thrust of the spring 58 on the guide rod 56 is equal to the thrust applied by the airflow to the circular plate 57. After the circular hole 27 is misaligned with the discharge port of the storage hopper 51, due to the fit between the soft pad 24 and the bottom end of the air guide tube 55, the gas in the liquid storage cylinder 61 will not continue to flow into the storage hopper 51. At this time, the circular plate 57 loses the thrust applied by the airflow. Due to the push of the spring 58 on the guide rod 56, the guide rod 56 pulls the circular plate 57 to move quickly toward the filter plate 53, so that a strong collision occurs between the circular plate 57 and the filter plate 53, and then the storage hopper 51 vibrates to a certain extent, thereby breaking the equilibrium state of the Chinese medicine seeds stuck in the storage hopper 51, so that the Chinese medicine seeds in the storage hopper 51 can fall normally, so as to avoid the situation where the Chinese medicine seeds in the storage hopper 51 are stuck and cannot fall.
