Technical effects and advantages of the present invention: Compared with the prior art, the Chinese herbal medicine extraction device proposed by the present invention has the following advantages:

1. In order to solve the problem that the residue after squeezing remains inside and is difficult to remove, even if an open door structure is provided, the residue will adhere to the support plate after the Chinese herbal medicine is strongly squeezed, which requires technicians to handle it by hand or with additional tools, affecting the efficiency of physical squeezing and juice extraction. The present invention cooperates a juice pressing mechanism with a grass gathering mechanism. After the juice pressing mechanism squeezes the juice out of the Chinese herbal medicine, the grass gathering mechanism is used to gather the residue after squeezing the juice to the middle. On the one hand, the residue is concentrated, which is convenient for technicians to take out; on the other hand, the process of picking out the adhered residue by hand or with tools is reduced, thereby improving the operational efficiency of physical juice extraction.

2. The present invention realizes the change of the state of the limit block by rotating the nut at the top, the nut drives the rotating shaft to rotate, and the rotating shaft drives the limit block at the bottom to rotate. When the limit block is parallel to the leakage groove, since the width of the limit block is smaller than the width of the leakage groove, the limit block cannot be stuck at the bottom of the support plate, and the tooth plate and the comb teeth can be easily lifted at this time; when the limit block and the leakage groove are in a cross state, such as a vertical state, since the length of the limit block is larger than the width of the leakage groove, the limit block is stuck under the support plate to form a locked state, so that the comb teeth and the tooth plate cannot be removed from the support plate, and it is also guaranteed that they can slide smoothly on the support plate and will not fall off. Through the process of changing the posture of the limit block, the state of the comb teeth and the tooth plate on the support plate is changed, so as to achieve the purpose of quick installation and maintenance, and also ensure that the comb teeth and the tooth plate can work reliably on the support plate.

3. The present invention uses the upward movement of the pressure plate to drive the lever circumferentially through the setting of the toggle assembly. The circumferential drive of the toggle rod forms intermittent toggling of the tooth plate, so that the tooth plate reciprocates and scrapes the surface of the support plate multiple times, thereby removing the residue adhered to the surface of the support plate and moving the residue on both sides to the middle, which is convenient for the subsequent slag removal work of the technicians.

Detailed ways

The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The present invention provides a Chinese herbal medicine extraction device as shown in Figures 1-6,

The invention comprises a juice pressing box 1, wherein a juice pressing mechanism 2 is provided in the juice pressing box 1, wherein a grass gathering mechanism 3 is installed in the juice pressing box 1, wherein the grass gathering mechanism 3 is used to gather the residue on the juice pressing mechanism 2, wherein a sealing door 4 is installed on one side wall of the juice pressing box 1, wherein a filter screen 5 is suspended at the bottom of the juice pressing box 1, and a gathering box body 6 with an upper opening is provided below the filter screen 5. In order to solve the problem that the residue after squeezing is left inside and is difficult to remove, even if an open door structure is provided, the residue after the Chinese herbal medicine is strongly squeezed will adhere to the support plate 24, which will cause the technicians to handle it by hand or with additional tools, thus affecting the efficiency of physical squeezing and extracting juice, the present invention cooperates with the juice pressing mechanism 2 and the grass gathering mechanism 3, wherein after the juice pressing mechanism 2 squeezes the juice out of the Chinese herbal medicine, the grass gathering mechanism 3 is used to gather the residue after squeezing the juice to the middle, thereby on the one hand concentrating the residue and facilitating the technicians to remove it; on the other hand, the process of picking out the adhered residue by hand or with tools is reduced, thereby improving the operation efficiency of physical juice extraction.

The juice pressing mechanism 2 includes a pressing plate 21, the top of which is fixedly connected to the end of a telescopic column 22, the bottom of which is convex, and the telescopic column 22 is fixedly mounted on the top of the juice pressing box 1 through a mounting frame 23. The pressing plate 21 is driven by the telescopic column 22 to move up and down in the juice pressing box 1. A support plate 24 is installed in the juice pressing box 1, and the support plate 24 is provided with evenly distributed leakage grooves 25. The support plate 24 is arranged in a concave structure and is arranged in coordination with the bottom of the pressing plate 21. The working process of the juice pressing mechanism 2 is as follows: the sealed door 4 is opened along the hinge, and then the Chinese herbal medicine to be extracted is placed on the support plate 24. At this time, the Chinese herbal medicine is located between the support plate 24 and the pressing plate 21. The sealed door 4 is closed. Since the protrusions and depressions between the support plate 24 and the pressing plate 21 fit together, when the electric telescopic column 22 is extended, the pressing plate 21 is pushed down and gradually presses the Chinese herbal medicine on the support plate 24 until the two are pressed to the limit state, thereby squeezing out the juice of the Chinese herbal medicine and dripping from the leakage groove 25 below into the collection box body 6 for collection. After it is fully collected, it is sent to the low-temperature extraction device for the next step of extraction.

Displacement grooves 27 are provided on the opposite side walls of the juice pressing box 1, and pillars 28 are fixed on both sides of the support plate 24, and the two pillars 28 are respectively inserted into the corresponding displacement grooves 27, and a return spring 29 is connected between the displacement grooves 27 and the pillars 28. When the support plate 24 is subjected to the force of the upper pressing plate 21, the pillars 28 on both sides of the support plate 24 will first compress the return springs 29 for buffering, and then contact the pressing plate 21 to squeeze out the juice, thereby avoiding damage caused by direct strong impact between the support and the pressing plate 21 on the one hand, and on the other hand, after the pressing plate 21 moves up and detaches, the return spring 29 of the spring return will drive the pillars 28 and the support plate 24 to return, forming an upward shaking effect, thereby facilitating the removal of the residue after the juice is squeezed from the support plate 24 and reducing the situation of residue adhesion.

The grass gathering mechanism 3 includes two groups of comb teeth 31, which are inserted into the leakage groove 25 one by one, and the top of each group of comb teeth 31 is fixed on a tooth plate 32. The two tooth plates 32 are provided with inclined surfaces on one side of the center of the support plate 24, and the two tooth plates 32 are disposed at both ends of the leakage groove 25. Through the arrangement of the comb teeth 31 and the tooth plate 32, when opening the sealing door 4 to collect the residue, the technician only needs to move the tooth plates 32 on both sides, and the comb teeth 31 at the bottom of the tooth plates 32 will slide along the leakage grooves 25 on the support plate 24. The tooth plates 32 and the comb teeth 31 on both sides cooperate in scraping to gather the residue attached to the support plate 24 to the middle and force the residue to leave the surface of the support plate 24, thereby playing a role of closing and scraping, making it convenient for technicians to collect the residue, saving the time for removing the residue, and improving work efficiency. The tooth plate 32 is arranged to be an inclined surface toward the center side of the support plate 24, so that the convex part of the pressure plate 21 contacts and fits with the inclined surface, thereby preventing the tooth plate 32 from interfering with the juice pressing action when the pressure plate 21 and the support plate 24 cooperate.

A telescopic spring 34 is connected between the tooth plate 32 and the side wall of the support plate 24. The reset spring 29 is provided to pull the tooth plate 32 to automatically reset, without the need for technicians to reset the tooth plate 32, thereby improving the convenience of the grass-collecting mechanism 3.

The comb teeth 31 on both sides of the tooth plate 32 are penetrated by through holes 35, and a rotating shaft 36 is inserted into the through hole 35. The top of the rotating shaft 36 extends out from above the tooth plate 32 and is fixed with a nut 37, and the bottom of the rotating shaft 36 extends out from below the comb teeth 31 and is fixed with a limiting block 38. The width of the limiting block 38 is smaller than the width of the leakage groove 25, and the length of the limiting block 38 is greater than the width of the leakage groove 25. By rotating the nut 37 at the top, the nut 37 drives the rotating shaft 36 to rotate, and the rotating shaft 36 drives the limiting block 38 at the bottom to rotate, so as to realize the change of the state of the limiting block 38. When the limiting block 38 is parallel to the leakage groove 25, since the width of the limiting block 38 is less than the width of the leakage groove 25, the limiting block 38 cannot be stuck at the bottom of the support plate 24, and the tooth plate 32 and the comb teeth 31 can be easily lifted at this time; when the limiting block 38 and the leakage groove 25 are in a cross state, such as a vertical state, since the length of the limiting block 38 is greater than the width of the leakage groove 25, the limiting block 38 is stuck under the support plate 24 to form a locked state, so that the comb teeth 31 and the tooth plate 32 cannot be removed from the support plate 24, and it is also ensured that they can slide smoothly on the support plate 24 and will not fall off. Through the process of changing the posture of the limiting block 38, the state of the comb teeth 31 and the tooth plate 32 on the support plate 24 is changed, so as to achieve the purpose of quick installation and maintenance, and also ensure that the comb teeth 31 and the tooth plate 32 can work reliably on the support plate 24.

The grass gathering mechanism 3 includes a toggle assembly 33, which is located on the side wall of the juice pressing box 1 opposite to the sealing door 4. The toggle assembly 33 can toggle the residue on the supporting plate 24 to gather toward the middle.

The toggle assembly 33 includes a rack 331, which is fixedly connected to the pressure plate 21 via a bent connecting plate 332. The rack 331 is placed vertically and can mesh with a gear 333. The gear 333 is rotatably mounted on the side wall of the juice pressing box 1. The gear 333 axis of the gear 333 penetrates the side wall of the juice pressing box 1 and is fixedly connected to a toggle rod 334. A groove 335 is provided on the side wall of the juice pressing box 1 for the toggle rod 334 to enter. An annular groove is provided on the gear 333, and the telescopic end of a push rod motor 336 is slidably connected in the annular groove. The push rod motor 336 is fixedly mounted on the side wall of the juice pressing box 1 on the same side as the gear 333.

Before the pressing plate 21 moves downward, the push rod motor 336 extends, thereby pushing the gear 333 away from the side wall of the juice pressing box 1. At this time, the gear 333 is pushed to disengage from the rack 331 in the prohibited state, and the gear 333 shaft of the gear 333 pulls the connected lever 334 to move backward, so that the lever 334 is just located in the receiving groove 335, avoiding the normal downward movement of the pressing plate 21 to squeeze the juice. When the pressing plate 21 passes over the receiving groove 335 during the upward process of squeezing, the push rod motor 336 shortens, thereby pulling the gear 333 close to the side wall of the juice pressing box 1 and re-engaging with the rack 331. At this time, the pressing plate 21 continues to move upward, and the horizontal lever 334 disengages from the receiving groove 335. Since the end of the push rod motor 336 is slidably connected to the annular groove on the gear 333, the push rod motor 336 does not interfere with the normal rotation of the gear 333. The toothed plate 32 is moved along the groove 25 so that the toothed plate 32 and the comb teeth 31 at the bottom can automatically scrape the residue and gather the residue to the middle. When the movement reaches a certain trajectory, the end of the lever 334 passes over the toothed plate 32, and the toothed plate 32 is automatically reset under the action of the telescopic spring 34, waiting for the next arrival of the lever 334, and the action of scraping the residue can be realized repeatedly in this way.

It should be noted that two racks 331 are provided, and the teeth of the two racks 331 are arranged in opposite directions, so the two gears 333 meshing therewith rotate in opposite directions, so that the two levers 334 both move the tooth plate 32 toward the middle, completing the action of gathering the residue;

By setting the toggle assembly 33, the upward movement of the pressure plate 21 is utilized to drive the lever 334 circumferentially. The circumferential drive of the lever 334 forms an intermittent toggle of the tooth plate 32, so that the tooth plate 32 reciprocates and scrapes the surface of the support plate 24 multiple times, thereby removing the residue adhered to the surface of the support plate 24 and moving the residue on both sides to the middle, which is convenient for the technicians to perform subsequent slag removal work.
