Technical Field
[0001] This utility model belongs to the field of traditional Chinese medicine planting technology, specifically relating to a root and stem recovery device for traditional Chinese medicine planting. Background Technology
[0002] The recovery of rhizomes is a crucial step in the cultivation and harvesting of Chinese medicinal herbs. Because these herbs grow underground, their rhizomes are often covered with a significant amount of soil. During recovery, it is essential to effectively separate the rhizomes from the soil to ensure the cleanliness of the herbs and the quality of subsequent processing.
[0003] However, traditional rhizome recycling methods mostly rely on manual hand tools to knock off the soil. This method is not only labor-intensive and time-consuming, but also inefficient and cannot meet the needs of large-scale production. Although existing rhizome recycling devices have improved recycling efficiency to some extent, they still have the problems of simple structure and single function. These devices mainly separate the soil on the surface of the rhizome by simple shaking or vibration, which is difficult to completely remove the soil attached to the rhizome, resulting in unsatisfactory recycling quality. Utility Model Content
[0004] To overcome the problems of time-consuming, labor-intensive, and inefficient traditional manual methods of removing soil from the surface of Chinese herbal medicine roots and stems, as well as the shortcomings of existing recycling devices that are simple in structure and have limited function, resulting in incomplete separation of roots and stems from soil, this utility model provides a root and stem recycling device for Chinese herbal medicine cultivation. A vibration mechanism drives a sieve disc to reciprocate, causing the roots and stems of the Chinese herbal medicine to tumble continuously within a washing tank. Combined with the flexible scrubbing action of the silicone brushes on the inner wall of the washing tank, the soil adhering to the surface of the roots and stems can be peeled off. A secondary cleaning mechanism then further removes residual soil, ensuring the cleanliness of the root and stem surface. This significantly improves soil separation efficiency and root and stem recycling quality, solving the problems of time-consuming and labor-intensive traditional manual methods and the limited function and incomplete separation of existing devices.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A root and stem recovery device for Chinese herbal medicine planting mainly includes a frame, a washing tank, a vibration mechanism, a motor, silicone brushes, and a washing mechanism. The washing tank is fixedly installed at the center of the frame by bolts. A plurality of silicone brushes are evenly arranged along the circumference of the inner wall of the washing tank, with the axis of the silicone brushes pointing to the center of the washing tank, and their ends are fixed to the inner wall of the washing tank by heat fusion bonding. A vibration mechanism for shaking the Chinese herbal medicine is installed at the center of the washing tank. The vibration mechanism includes a rotating shaft, a sieve plate, a turntable, a connecting plate, a guide rod, rollers, springs, and protrusions. The motor is fixedly installed at the bottom of the washing tank by bolts. The rotating shaft is installed at the center of the bottom of the washing tank through a bearing, and its bottom end passes through the washing tank and is connected to the motor through a coupling. The output shaft is connected to the drive, and a turntable is bolted to the top. Several connecting plates are evenly welded to the turntable along the circumference. The end of the connecting plate has a guide hole, and a linear bearing is embedded in the guide hole. The screen is located inside the cleaning tank, and the gap between its outer edge and the inner wall of the cleaning tank is 1 mm to 1 mm. Guide rods corresponding to the positions of the guide holes are evenly arranged along the circumference of the bottom surface of the screen. The bottom end of the guide rod passes through the guide hole and is slidably connected to the connecting plate through the linear bearing. A roller is installed at the bottom end of the guide rod, and the roller makes rolling contact with the bottom of the inner wall of the cleaning tank. A spring is sleeved on the guide rod, with its top end abutting against the bottom of the connecting plate and its bottom end abutting against the limiting block at the bottom of the guide rod. Several protrusions are evenly welded to the bottom of the cleaning tank along the movement trajectory of the roller. The protrusions are arc-shaped surfaces that are narrower at the top and wider at the bottom. A cleaning mechanism is installed inside the cleaning tank.
[0006] The cleaning mechanism includes a water supply pipe, a ring branch pipe, spray heads, and a water pump. The ring branch pipe is installed on the top of the cleaning tank by fasteners. Several downward-sloping spray heads are evenly connected along the circumference of the ring branch pipe. The water pump is installed on the frame by bolts. One end of the water supply pipe is connected to the outlet of the water pump through a flange, and the other end is connected to the ring branch pipe.
[0007] The bottom of the inner wall of the cleaning tank is welded with an annular baffle shell. The diameter of the annular baffle shell is larger than the diameter of the movement trajectory at the end of the connecting plate. The bottom of the screen is welded with an annular guide hood. The height of the annular guide hood is the same as the height of the annular baffle shell. Its inner diameter is larger than the outer diameter of the annular baffle shell and it is fitted outside the annular baffle shell. Several filter holes are evenly opened on the screen in the outer area of the annular guide hood.
[0008] The cleaning tank has a discharge chute on its side wall near the bottom. A baffle plate is slidably connected between the discharge chute and the outer wall of the cleaning tank. A handle is welded to the outer wall of the baffle plate. A mud discharge chute is welded to the bottom of the cleaning tank and is located outside the annular baffle shell.
[0009] The beneficial effects of this utility model are: This invention uses a vibration mechanism to drive the sieve disc to shake back and forth, causing the roots and stems of Chinese medicinal herbs to tumble continuously inside the washing tank. Combined with the gentle scrubbing action of the silicone brushes on the inner wall of the washing tank, the soil attached to the surface of the roots and stems can be peeled off. The roots and stems are then washed a second time by the washing mechanism to further remove residual soil, ensuring the cleanliness of the root and stem surface. This significantly improves the soil separation efficiency and the quality of root and stem recovery, solving the problems of time-consuming and labor-intensive traditional manual knocking methods and the limited functionality and incomplete separation of existing devices.

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0015] This utility model discloses a root and stem recovery device for Chinese herbal medicine planting. The device includes a frame 1, a washing tank 2, a vibration mechanism 3, a motor 4, silicone brushes 5, and a washing mechanism 6. The frame 1 is the supporting structure of the entire device and is welded from steel. The washing tank 2 is fixedly installed at the center of its top by bolts. The washing tank 2 is a cylindrical structure, and a number of silicone brushes 5 are evenly arranged along the circumference of the inner wall. The axis of the silicone brushes 5 points to the center of the washing tank 2, and the ends are fixed to the inner wall of the washing tank 2 by hot melt bonding. The length of the silicone brushes 5 is less than the radius of the washing tank 2 to ensure that they can contact the surface of the Chinese herbal medicine roots and stems on the sieve plate 302 during operation.
[0016] A vibration mechanism 3 is installed at the center inside the cleaning tub 2. The vibration mechanism 3 includes a rotating shaft 301, a screen plate 302, a turntable 303, a connecting plate 304, a guide rod 305, a roller 306, a spring 307, and a protrusion 308. The motor 4 is fixedly installed at the bottom of the cleaning tub 2 by bolts. The rotating shaft 301 is installed at the center of the bottom of the cleaning tub 2 by bearings. The bottom end of the rotating shaft 301 passes through the cleaning tub 2 and is connected to the output shaft of the motor 4 by a coupling. A turntable 303 is installed at the top. Several connecting plates 304 are evenly welded on the turntable 303 along the circumference. A guide hole is opened at the end of the connecting plate 304. A linear bearing is embedded in the guide hole. The linear bearing is used to reduce the friction of the guide rod 305 in the guide hole. The sieve disc 302 is located inside the washing tank 2, and the gap between its outer edge and the inner wall of the washing tank 2 is 1-3 mm. Guide rods 305 corresponding to the positions of guide holes are evenly arranged on the bottom surface of the sieve disc 302 along the circumferential direction. The bottom end of the guide rod 305 passes through the guide hole and is slidably connected to the connecting plate 304 through a linear bearing. A roller 306 is installed at the bottom end of the guide rod 305 by bolts. The roller 306 rolls in contact with the bottom of the inner wall of the washing tank 2. A spring 307 is sleeved on the guide rod 305. The top end of the spring 307 abuts against the bottom of the connecting plate 304, and the bottom end abuts against the limiting block at the bottom of the guide rod 305. Several protrusions 308 are evenly welded on the bottom of the washing tank 2 along the movement trajectory of the roller 306. The cross-sectional shape of the protrusion 308 is an arc-shaped surface that is narrow at the top and wide at the bottom. After the motor 4 starts, its output shaft drives the rotating shaft 301 to rotate, and the rotating shaft 301 drives the turntable 303 to rotate synchronously. The turntable 303 drives the guide rod 305 to make a circular motion through the connecting plate 304. Since the roller 306 rolls in contact with the bottom of the inner wall of the cleaning tank 2, and the bottom of the cleaning tank 2 is welded with a protrusion 308, when the roller 306 passes the protrusion 308, the roller 306 is subjected to the arc surface force of the protrusion 308, causing the guide rod 305 to move upward along the guide hole. At the same time, the spring 307 is compressed. When the roller 306 leaves the protrusion 308, the spring 307 returns to its original state, and the guide rod 305 moves downward, thereby causing the sieve plate 302 to make up-down reciprocating motion. The up-down reciprocating motion of the sieve plate 302 causes the roots and stems of the Chinese herbal medicines placed on it to roll continuously, thereby achieving the effect of soil removal.
[0017] A cleaning mechanism 6 is installed inside the cleaning tank 2. The cleaning mechanism 6 includes a water supply pipe 601, a ring branch pipe 602, spray heads 603, and a water pump 604. The ring branch pipe 602 is installed on the top of the cleaning tank 2 by fasteners. Several downward-sloping spray heads 603 are evenly connected to the ring branch pipe 602 along the circumference. The tilt angle of the spray heads 603 is between 30 and 45 degrees. The water pump 604 is installed on the frame 1 by bolts. One end of the water supply pipe 601 is connected to the outlet of the water pump 604 through a flange, and the other end is connected to the ring branch pipe 602 through a threaded connection sleeve. After the water pump 604 is started, water flows through the water supply pipe 601 into the ring branch pipe 602 and is sprayed out from the spray heads 603. The water flow from the spray heads 603 covers the roots and stems of Chinese herbal medicines on the sieve plate 302, completing the secondary cleaning of the roots and stems.
[0018] An annular baffle shell 201 is welded to the bottom of the inner wall of the cleaning tank 2. The diameter of the annular baffle shell 201 is larger than the diameter of the movement trajectory at the end of the connecting plate 304. An annular guide shroud 309 is welded to the bottom of the screen plate 302. The height of the annular guide shroud 309 is the same as the height of the annular baffle shell 201, and its inner diameter is larger than the outer diameter of the annular baffle shell 201. It is fitted over the annular baffle shell 201. The design of the annular baffle shell 201 and the annular guide shroud 309 can prevent sewage or separated soil from entering the interior of the annular baffle shell 201, thereby protecting the components of the vibration mechanism 3 from contamination and extending the service life of the device. Several filter holes 310 are evenly opened on the screen plate 302 in the outer area of the annular guide shroud 309 to discharge the stripped soil and water to the outer area of the annular guide shroud 309.
[0019] A discharge trough 7 is provided on the side wall of the washing tank 2 near the bottom. A baffle plate 8 is slidably connected between the discharge trough 7 and the outer wall of the washing tank 2. A handle 801 is welded to the outer wall of the baffle plate 8. After cleaning, the baffle plate 8 can be pulled out through the handle 801 for easy removal of the cleaned Chinese herbal root stems. A mud discharge trough 9 is welded to the bottom of the washing tank 2. The mud discharge trough 9 is located in the outer area of the annular baffle shell 201 and is used to collect the mud and sewage discharged from the filter hole 310 for centralized treatment.
[0020] The working principle of this utility model is as follows: First, the roots and stems of the Chinese herbal medicine to be cleaned are placed on the sieve plate 302. The motor 4 is started. The motor 4 drives the turntable 303 to rotate through the rotating shaft 301. The turntable 303 drives the guide rod 305 to make a circular motion through the connecting plate 304. When the roller 306 rolls at the bottom of the cleaning tank 2 and passes the protrusion 308, the guide rod 305 and the sieve plate 302 produce up-and-down reciprocating motion. The shaking of the sieve plate 302 causes the roots and stems of the Chinese herbal medicine to roll continuously in the cleaning tank 2, vibrating off the soil adhering to the roots and stems. At the same time, the silicone brush rod 5 is used to gently brush the surface of the roots and stems. The peeled soil falls into the outer area of the annular guide shroud 309 through the filter holes 310 on the sieve plate 302. After most of the soil on the Chinese herbal medicine roots and stems has been removed, the water pump 604 is started. The water pump 604 delivers water through the water supply pipe 601 to the annular branch pipe 602, and sprays it out from the spray head 603. The water flow performs a secondary cleaning of the Chinese herbal medicine roots and stems on the sieve plate 302, further removing residual soil. After cleaning, the baffle plate 8 is pulled out through the handle 801, and the cleaned Chinese herbal medicine roots and stems are taken out from the discharge trough 7. The soil and sewage in the mud discharge trough 9 can be centrally treated.
[0021] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principles of this utility model are further supplemented below in conjunction with specific application scenarios.
[0022] In actual operation, the roots and stems of the Chinese herbal medicines to be processed are first placed on the surface of the sieve plate 302. After starting the motor 4, its output shaft drives the rotating shaft 301 to rotate through the coupling. The rotating shaft 301 drives the turntable 303 to rotate synchronously. The rotational motion of the turntable 303 is transmitted to the guide rod 305 through the connecting plate 304, causing the guide rod 305 to make a circular motion. When the roller 306 passes the protrusion 308 welded to the bottom of the washing tank 2, the arc-shaped surface design causes the roller 306 to be subjected to an upward force, and the guide rod 305 moves upward accordingly. When the spring 307 is compressed, and the roller 306 leaves the protrusion 308, the spring 307 returns to its original state, and the guide rod 305 moves downward, thereby realizing the up-and-down reciprocating shaking of the sieve disc 302, causing the roots and stems of Chinese herbal medicines to roll continuously on the sieve disc 302, vibrating off the soil adhering to the roots and stems, while ensuring that the surface of the roots and stems is in full contact with the silicone brush rod 5. The silicone brush rod 5 peels off the soil adhering to the surface of the roots and stems through a flexible brushing action. The peeled soil falls into the outer area of the annular guide shroud 309 through the filter holes 310 on the sieve disc 302.
[0023] After most of the soil on the roots and stems of the Chinese medicinal herbs has been removed, the water pump 604 is activated. Water is delivered through the water supply pipe 601 to the annular branch pipe 602 and sprayed out by the spray head 603. The spray head 603 is designed with an inclination angle between 30 and 45 degrees to effectively cover the roots and stems of the Chinese medicinal herbs on the sieve plate 302. The roots and stems are then washed a second time by the water flow to further remove residual soil particles. Due to the coordinated design of the annular baffle shell 201 and the annular guide hood 309, the wastewater and separated soil are confined to the outer area of the annular guide hood 309, preventing them from entering the interior of the annular baffle shell 201 and contaminating the components of the vibration mechanism 3, thereby extending the service life of the device.
[0024] After cleaning, the baffle plate 8 is pulled out along the slide rail using the handle 801, opening the discharge chute 7 to remove the cleaned Chinese herbal rootstocks. The mud discharge chute 9, located outside the annular baffle shell 201, collects the mud and wastewater discharged from the filter holes 310 for subsequent centralized treatment. This process not only improves the efficiency of mud separation but also ensures the cleanliness of the rootstock surface, meeting the high requirements of the modern Chinese herbal medicine planting industry for recycling quality.
[0025] As can be seen from the above steps, the rotation of the turntable 303 driven by the motor 4, along with the coordinated action of the connecting plate 304, guide rod 305, roller 306, and spring 307, achieves the up-and-down reciprocating motion of the sieve disc 302. Furthermore, the combination of the flexible brushing of the silicone brush rod 5 and the water rinsing of the spray head 603 enables efficient soil removal. The design of the annular baffle shell 201 and the annular guide shroud 309 effectively isolates wastewater and soil, protecting the components of the vibration mechanism 3, thereby improving the overall reliability and service life of the device. The above structure and its operating principle together solve the problems of low efficiency in traditional manual tapping methods and the limited functionality of existing devices, achieving high efficiency and thoroughness in soil separation during the recovery of Chinese herbal medicine roots and stems.
[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
