Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine processing technology, specifically relating to an intelligent grinding device for edible traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to raw medicinal materials used under the guidance of traditional Han Chinese medicine. It has a long history in my country and is the material basis for the development of Chinese medicine. For thousands of years, it has been used as the main weapon for preventing and treating diseases, playing an indispensable role in protecting people's health and the reproduction of the nation. There are many types of TCM, and a large part of them can be eaten. When processing these edible TCM materials, they generally need to be ground into small granules so that patients can swallow them.

[0003] Existing grinding devices for traditional Chinese medicine often employ multiple stages of grinding mechanisms, from coarse to fine, to achieve a fine grinding effect. This results in large equipment size, the need for numerous motors, high initial investment costs, and high energy consumption. Therefore, we propose an intelligent grinding device for edible traditional Chinese medicinal materials. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent grinding device for edible Chinese medicinal materials to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: An intelligent grinding device for edible Chinese medicinal materials includes a grinding chamber and a discharge section arranged sequentially from top to bottom. A grinding mechanism is provided inside the grinding chamber. The grinding mechanism includes an outer cylinder, a grinding table, and a motor. A conical cylinder is integrally connected to the lower end of the outer cylinder, and the grinding table is located inside the conical cylinder. The inner diameter of the lower end of the conical cylinder is smaller than that of the upper end. Several uniformly arranged first grinding strips are machined inside the conical cylinder. The lower end of the conical cylinder is closed and has several through holes. A mounting housing is fixedly connected to the bottom of the conical cylinder. The motor is installed and fixed inside the mounting housing. The output shaft of the motor passes through the conical cylinder and is fixedly connected to the middle of the grinding table. The grinding table has a conical platform that is larger at the top and smaller at the bottom. Several evenly arranged second grinding strips are machined on the outer surface of the conical platform. The conical platform and the conical cylinder have different inclinations. The distance between the lower end of the conical platform and the lower end of the conical cylinder is the minimum distance, and the distance between the upper end of the conical platform and the upper end of the conical cylinder is the maximum distance. The discharge section is located below the grinding chamber.

[0006] A cover is fixedly installed on the lower side of the conical cylinder, and the cover is flush with the lower side of the mounting housing. The discharge section includes a base, a bracket, a platform, and an annular collection box. The base and the platform are fixedly connected by the bracket. The cover is fixedly connected with multiple connecting rods that are fixedly connected to the platform. The motor is located inside the annular collection box. The inner and outer sides of the annular collection box correspond to the cover and the mounting housing, respectively. The platform has a through groove that matches the annular collection box. A locking element is provided between the platform and the annular collection box.

[0007] The locking component includes multiple limiting screws located on each side of the platform. The limiting screws are threadedly connected to the platform and pass through the through groove. The upper surfaces of the inner and outer sides of the annular collection box abut against the cover and the mounting housing, respectively. The lower surface of the annular collection box abuts against each of the limiting screws. The distance between the base and the platform is greater than the height of the annular collection box.

[0008] The inner and outer upper surfaces of the annular collection box are also provided with mounting ring grooves.

[0009] The outer cylinder is also provided with a ring cover, and a ring plate is fixedly connected to the inner side of the ring cover. The ring plate extends downward to the upper surface of the grinding table but is not fixed to it. The ring plate has symmetrically opened material leakage ports. A storage hopper is also provided on the upper side of the grinding chamber. A closed ring sleeve that is slidably connected to the ring plate is provided on the lower side of the storage hopper. An annular groove matching the closed ring sleeve is opened on the upper surface of the grinding table. A wedge block is provided on the lower side of the closed ring sleeve. A wedge platform matching the wedge block is machined inside the annular groove. Several spring rods are fixedly connected between the storage hopper and the outer cylinder.

[0010] The motor is a DC motor, and its output shaft can be manually rotated after the motor is powered off.

[0011] The storage hopper is also equipped with a turning mechanism, which includes a sleeve, blades and a connecting frame. The sleeve is rotatably connected to the upper surface of the grinding table. The blades are multiple and evenly installed on the outer side of the sleeve. The connecting frame is fixedly connected to the storage hopper. The connecting frame is fixedly connected to a sliding rod that is slidably connected to the sleeve. A transmission component is provided between the sliding rod and the sleeve.

[0012] The inner side of the sleeve is provided with a spiral guide groove extending vertically, the spiral guide groove having at least one turn, and the slide rod is machined with a guide head that matches the spiral guide groove.

[0013] This invention, by setting conical platforms and conical cylinders with different inclinations, enables continuous grinding of Chinese medicinal materials from large to small during the grinding process, until the ground medicinal material particles meet the minimum distance between the lower end of the conical platform and the lower end of the conical cylinder. This ensures the fineness of the grinding of Chinese medicinal materials. Furthermore, the grinding chamber does not use a multi-stage grinding mechanism, resulting in a small equipment size, fewer motors required, and low energy consumption. Attached Figure Description

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Example 1, such as Figure 1 and Figure 2 The intelligent grinding device for edible Chinese medicinal materials shown includes a grinding chamber 100 and a discharge section 110 arranged sequentially from top to bottom. The grinding chamber 100 is equipped with a grinding mechanism, which includes an outer cylinder 101, a grinding table 102 and a motor 103. A conical cylinder 104 is integrally connected to the lower end of the outer cylinder 101, and the grinding table 102 is located inside the conical cylinder 104. The inner diameter of the lower end of the conical cylinder 104 is smaller than that of the upper end. Several uniformly arranged first grinding strips 1041 are machined inside the conical cylinder 104. The lower end of the conical cylinder 104 is closed and has several through holes 1042. A mounting housing 105 is fixedly connected to the bottom of the conical cylinder 104. The motor 103 is installed and fixed inside the mounting housing 105. The output shaft of the motor 103 passes through the conical cylinder 104 and is fixedly connected to the middle of the grinding table 102. The grinding table 102 has a conical platform 106 that is larger at the top and smaller at the bottom. The outer surface of the conical platform 106 has several evenly arranged second grinding strips 1061. The conical platform 106 and the conical cylinder 104 have different inclinations. The distance between the lower end of the conical platform 106 and the lower end of the conical cylinder 104 is the minimum distance, and the distance between the upper end of the conical platform 106 and the upper end of the conical cylinder 104 is the maximum distance. The discharge section 110 is located below the grinding chamber. A cover 1043 is fixedly installed on the lower side of the conical cylinder 104. The cover 1043 is flush with the lower side of the mounting housing 105. The discharge section 110 includes a base 111, a bracket 112, a platform 113, and an annular collection box 114. The base 111 and the platform 113 are fixedly connected by the bracket 112. The cover 1043 is fixedly connected to multiple connecting rods 1044 that are fixedly connected to the platform 113. The motor 103 is located inside the annular collection box 114. The inner and outer sides of the annular collection box 114 correspond to the cover 1043 and the mounting housing 105, respectively. The platform 113 has a through groove 1131 that matches the annular collection box 114. A locking element is provided between the platform 113 and the annular collection box 114.

[0018] The base 111 can be fixed to the platform 113 as a whole through the bracket 112, and the platform 113 can be fixed to the cover 1043 as a whole through the connecting rod 1044, so that the outer cylinder 101, the conical cylinder 104, the cover 1043 and the platform 113 can form a whole and be placed stably. Meanwhile, the mounting housing 105 at the bottom of the conical cylinder 104 can mount the motor 103, thus making the whole device a whole. When the motor 103 starts and drives the output shaft to rotate, the grinding table 102 can rotate relative to the outer cylinder 101. The use of the device includes the following steps: Step ①: Place the annular collection box 114 into the through groove 1131 of the platform 113, so that the inner and outer sides of the annular collection box 114 are aligned with the cover 1043 and the mounting housing 105 respectively. Step 2: Use locking components to fix the annular collection box 114 so that the cover 1043, the mounting housing 105 and the annular collection box 114 together form an area for collecting and grinding Chinese medicinal materials; Step 3: Start the motor 103 to make the grinding table 102 rotate relative to the outer cylinder 101, and then people can continuously add Chinese medicinal materials into the outer cylinder 101 for grinding; Step 4: During the grinding process, due to the different inclinations of the conical platform 106 and the conical cylinder 104, the distance between the lower end of the conical platform 106 and the lower end of the conical cylinder 104 is the minimum distance, and the distance between the upper end of the conical platform 106 and the upper end of the conical cylinder 104 is the maximum distance. Therefore, the initial large particles of Chinese medicinal materials will enter between the upper end of the conical platform 106 and the upper end of the conical cylinder 104. Through the interaction of the first grinding strip 1041 on the inner wall of the conical cylinder 104 and the second grinding strip 1061 on the outer surface of the conical platform 106, the grinding materials will be ground. The process involves grinding large particles of Chinese medicinal herbs into smaller pieces. As the herbs become smaller, they move downwards and continue to be ground by the first grinding strip 1041 on the inner wall of the conical cylinder 104 and the second grinding strip 1061 on the outer surface of the conical platform 106. This continues until the herbs are small enough to pass between the lower end of the conical platform 106 and the lower end of the conical cylinder 104. At this point, the herbs have been ground to their smallest size and have entered the bottom of the conical cylinder 104, where they are discharged through multiple through holes 1042 at the bottom of the conical cylinder 104. Step 5: The small granules of Chinese medicinal materials discharged from the through hole 1042 at the bottom of the conical cylinder 104 fall into the annular collection box 114 for collection. When it is necessary to remove the ground small granules of Chinese medicinal materials, the locking part is released and the annular collection box 114 is removed from the through groove 1131 of the platform 113.

[0019] In this embodiment, by setting conical platforms and conical cylinders with different inclinations, the Chinese medicinal materials can be ground continuously from large to small during the grinding process until the ground Chinese medicinal material particles meet the minimum distance between the lower end of the conical platform and the lower end of the conical cylinder, thus ensuring the fineness of the grinding of Chinese medicinal materials. In addition, the grinding chamber does not use a multi-stage grinding mechanism, the equipment is small in size, requires fewer motors, and consumes less energy.

[0020] As a further explanation of the locking element in this embodiment, such as Figure 2 As shown, the locking component includes multiple limiting screws 115 located on each side of the platform 113. The limiting screws 115 are threadedly connected to the platform 113 and pass through the through groove 1131. The upper surfaces of the inner and outer sides of the annular collection box 114 abut against the cover 1043 and the mounting housing 105, respectively, and the lower surface of the annular collection box 114 abuts against each limiting screw 115. The distance between the base 111 and the platform 113 is greater than the height of the annular collection box 114.

[0021] Since the distance between the base 111 and the platform 113 is greater than the height of the annular collection box 114, when installing the annular collection box 114, it can be inserted from below the platform 113 upwards, so that the upper ends of the inner and outer sides of the annular collection box 114 are aligned with the cover 1043 and the mounting housing 105 respectively. Then, by locking the limiting screws 115 into each side of the platform 113, the limiting screws 115 abut against the annular collection box 114, thereby fixing the annular collection box 114 and preventing it from falling off. When removing the annular collection box 114, by loosening each limiting screw 115, the bottom of the annular collection box 114 will no longer be blocked by the limiting screw 115, and people can remove the annular collection box 114 from the through groove 1131 of the platform 113 from top to bottom, making the disassembly and assembly of the annular collection box 114 convenient.

[0022] As a further optimization of the discharge section 110 in this embodiment, mounting ring grooves are also provided on the upper surfaces of both the inner and outer sides of the annular collection box 114.

[0023] By setting the mounting groove, the upper ends of the inner and outer sides of the annular collection box 114 can be positioned with the cover 1043 and the mounting housing 105, further ensuring the alignment of the annular collection box 114.

[0024] Example 2 is a further improvement made based on Example 1 to reduce the frequency of manual material feeding, such as... Figures 3 to 7 As shown, the outer cylinder 101 is also provided with an annular cover 200. An annular plate 201 is fixedly connected to the inner side of the annular cover 200. The annular plate 201 extends downward to the upper surface of the grinding table 102 but is not fixed to each other. The annular plate 201 has symmetrically opened material leakage ports 202. A storage hopper 210 is also provided on the upper side of the grinding chamber 100. A closed ring sleeve 211 that is slidably connected to the annular plate 201 is provided on the lower side of the storage hopper 210. An annular groove 212 that matches the closed ring sleeve 211 is opened on the upper surface of the grinding table 102. A wedge block 213 is provided on the lower side of the closed ring sleeve 211. A wedge platform 214 that matches the wedge block 213 is machined inside the annular groove 212. Several spring rods 215 are fixedly connected between the storage hopper 210 and the outer cylinder 101.

[0025] The ring cover 200 is used to seal the upper side of the outer cylinder 101, and the storage hopper 210 is used to store a large amount of large-particle Chinese medicinal materials to be ground. In the initial state, the closing ring 211 of the storage hopper 201 extends into the annular groove 212 of the grinding table 102, sealing the material outlet 202 of the ring plate 201. At this time, the wedge-shaped block 213 of the closing ring 211 is misaligned with the wedge-shaped platform 214 inside the annular groove 212. Under the gravity of the storage hopper 201 and the elasticity of each spring rod 215, the wedge-shaped block 213 of the closing ring 211 abuts against the bottom of the annular groove 212, and the closing ring 211 abuts against the upper end of the wedge-shaped platform 214 inside the annular groove 212, thereby obtaining support, specifically as follows: Figures 4 to 7 As shown; As the grinding table 102 rotates, the storage hopper 210 is fixed to the outer cylinder 101 by multiple spring rods 215. Therefore, the grinding table 102 will drive the annular groove 212 and the wedge-shaped platform 214 to rotate relative to the storage hopper 210 and the closing ring 211. During the rotation, it is easy to predict, based on common sense, that after the wedge block 213 on the lower side of the closing ring 211 comes into contact with the wedge-shaped platform 214 of the annular groove 212, the guiding cooperation between the wedge block 213 and the wedge platform 214 will cause the closing ring 211 to rotate. The cylinder 211 drives the storage hopper 210 to move upward against the elastic force of each spring rod 215, so that the closing sleeve 211 no longer closes the leakage port 202 of the ring plate 201, and the large particles of Chinese medicinal materials to be ground in the storage hopper 210 will enter the grinding chamber 100; and after the grinding table 102 drives the annular groove 212 and the wedge-shaped platform 214 to once again deviate from the wedge block 213 of the closing sleeve 211, under the elastic rebound of the spring rod 215, the closing sleeve 211 will once again close the leakage port 202 of the ring plate 201; As can be seen from the above, as the grinding table 102 rotates continuously, the material can be fed from the storage hopper 210 once for each rotation of the grinding table 102, thus enabling automatic feeding and effectively reducing the frequency of manual feeding.

[0026] As a further limitation of this embodiment, the motor 103 is a DC motor, and its output shaft can be manually rotated after the power to the motor 103 is turned off.

[0027] The motor 103 is set as a DC motor. Since the output shaft of the DC motor can be manually rotated after the power is off, when the motor 103 is powered off, if the wedge block 213 is still in contact with the wedge platform 214, the storage hopper 210 is moving upward and stretching the spring rod 215. After the power is off, the output shaft of the motor 103 can be rotated under the rebound of the spring rod 215, so that the grinding table 102 drives the wedge platform 214 to rotate and disengage from the wedge block 213, and the storage hopper 210 can return to the initial position. The leakage port 202 of the ring plate 201 is sealed by the closing ring 211 to prevent the storage hopper 210 from leaking material into the grinding chamber 100 during secondary use.

[0028] Example 3 is an improvement on Example 2, made to avoid clogging during the feeding of medicinal herbs into the storage hopper 210. For example... Figures 8 to 9 As shown, the storage hopper 210 is also equipped with a turning mechanism, which includes a sleeve 300, blades 301 and a connecting frame 302. The sleeve 300 is rotatably connected to the upper surface of the grinding table 102. There are multiple blades 301 and they are evenly installed on the outer side of the sleeve 300. The connecting frame 302 is fixedly connected to the storage hopper 210. The connecting frame 302 is fixedly connected to a slide rod 303 that is slidably connected to the sleeve 300. A transmission component is provided between the slide rod 303 and the sleeve 300. The sleeve 300 has a spiral guide groove 304 extending vertically on its inner side. The spiral guide groove 304 has at least one turn. The slide rod 303 is machined with a guide head 305 that matches the spiral guide groove 304.

[0029] like Figure 9 As shown, when the storage hopper 210 is in the low position, the guide head 305 processed by the slide rod 303 of the connecting frame 302 is at the lowest end of the spiral guide groove 304 inside the sleeve 300. As the storage hopper 210 moves from the low position to the high position, the connecting frame 302 drives the slide rod 303 to move upward, thereby causing the guide head 305 to move upward. Through the cooperation of the guide head 305 and the spiral guide groove 304, the sleeve 300 rotates. Similarly, during the process of the storage hopper 210 returning from the high position to the low position, the sleeve 300 also rotates through the cooperation of the guide head 305 and the spiral guide groove 304. Therefore, as the storage hopper 210 moves up and down, allowing the large-particle Chinese medicinal materials inside the storage hopper 210 to enter the grinding chamber 100, the sleeve 300 will rotate synchronously with the movement of the storage hopper 210. This allows the blades 301 to turn over the large-particle Chinese medicinal materials during the feeding process, thus preventing blockage.

[0030] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
