Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine extraction equipment, in particular to a clean automatic feeding device for a medicinal material extraction workshop. Background Art

[0002] The extraction of traditional Chinese medicine is to use some technologies to extract the effective ingredients to the maximum extent, so as to improve the intrinsic quality and clinical treatment effect of traditional Chinese medicine preparations and maximize the effect of traditional Chinese medicine. When extracting medicinal materials, it is necessary to feed the medicinal materials so that the medicinal materials can be stably transported to the inside of the extraction tank.

[0003] To this end, Chinese patent application CN114194858A discloses a "clean and automatic feeding device for a medicinal material extraction workshop." Its main structure includes a feeding box, a fixed feeding tube, and a telescopic tube. A limit ring plate is installed at the lower end of the fixed feeding tube, and a limit rod is installed inside each movable hole. A hanging block is fixed to the outer side of the lower end of the strip plate. Hanging openings are provided on the lower side of the limit ring plate on the outer side of the movable hole, corresponding to the location of the hanging block. An aluminum foil collecting tube is installed inside the telescopic tube directly below the limit ring plate. Curved blocks are fixed to the left and right sides of the lower side of the collecting tube. Spring ropes are installed inside each curved hole. A T-shaped ring plate is installed inside the telescopic tube directly below the collecting tube. This clean and automatic feeding device for medicinal material extraction workshops allows the telescopic tube to be disassembled and replaced by disconnecting the limit rod and the limit ring, thereby freeing the telescopic tube from the restricted position. Simultaneously, the T-shaped ring plate pulls on the spring rope to tighten the lower end of the collecting tube, achieving rapid adjustment of the tube opening and preventing the spillage of medicinal materials.

[0004] However, in the actual operation of the above-mentioned automatic feeding device for cleaning the medicinal material extraction workshop, since some Chinese medicinal materials are branch-shaped, they are easily accumulated during transportation in the pipe hole, resulting in the inability to discharge the medicinal materials in a quantitative manner. In addition, the above-mentioned T-shaped ring plate is used to pull the spring rope to tighten the lower end of the collecting aluminum foil tube to achieve the effect of rapid adjustment of the tube mouth. During the process of discharging the medicinal materials, it is impossible to control the falling speed and amount of the medicinal materials during the closing process of the tube mouth, resulting in a relatively poor degree of timely closure of the medicinal materials.

The lower conveying hole 9 for external feeding of medicinal materials, the driving motor 11 fixedly installed on the top of the funnel-shaped feeding shell 1 through the supporting connecting rod 10, and the upper docking plate 12 installed on the rotor end of the driving motor 11, the driving motor 11 has the function of rotating to the left and right. First, the medicinal materials are put into the funnel-shaped feeding chamber 3 through the feeding port 4. Under the action of gravity, the medicinal materials will be concentrated in the bottom recessed area of ​​the funnel-shaped feeding chamber 3. According to the required amount of medicinal materials, a certain amount of medicinal materials can be introduced, and the driving motor 11 can be started. The kinetic energy of the driving motor 11 is used to carry out directionally conveying the medicinal materials.

[0029] In order to realize the crushing and directional transportation of medicinal materials, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, it is necessary to set up a rotating medicinal material conveying mechanism 13, which is internally provided with an upper fixed plate 131 fixedly installed at the top of the columnar feeding chamber 8, a lower rotating plate 132 located just below the upper fixed plate 131 and capable of crushing the medicinal materials in cooperation with the upper fixed plate 131 when rotating, an upper spiral conveying impeller structure 136 that can rotate with the rotor of the driving motor 11 and drive the lower rotating plate 132 to rotate, and when it rotates, it can produce a directional conveying effect on the surrounding medicinal materials, and a lower spiral conveying impeller structure 1312 that rotates with the lower rotating plate 132 and can produce a directional conveying effect on the surrounding medicinal materials when it rotates. The rotation direction of the driving motor 11 is controlled, and first the rotation of the upper spiral conveying impeller structure 136 drives the medicinal materials located around it to move downward. At this time, the medicinal materials are continuously pressed into the conical inner cavity 134 and the conical platform structure 135. During the feeding process, the rotation of the lower rotating disk 132 will cause the medicinal materials in the area to be continuously ground and crushed into fine medicinal material particles, and the medicinal material particles will fall downward and accumulate under the action of gravity. At this time, since the spiral direction of the upper spiral conveying impeller structure 136 is opposite to the spiral direction of the lower spiral conveying impeller structure 1312, the rotating lower spiral conveying impeller structure 1312 will cause the medicinal material particles to move downward. At this time, the medicinal material particles will not fall downward until the quantitative medicinal materials are crushed. At this time, the crushed medicinal material particles will accumulate inside the columnar feeding chamber 8. When medicinal materials need to be added to the extraction tank, the driving motor 11 will produce the opposite rotation direction. At this time, the lower spiral conveying impeller structure 1312 causes the medicinal material particles around it to fall downward and enter the extraction tank, thereby realizing the crushing and directional conveying functions of the medicinal materials.

The bottom center of the lower rotating disk 132 is fixedly installed with the No. 3 rotating shaft 1311 that passes through the columnar feeding cavity 8 and the lower conveying hole 9, and the shaft body of the No. 3 rotating shaft 1311 is provided with a lower spiral conveying impeller structure 1312. The structural shape of the conical inner concave cavity 134 is consistent with the structural shape of the conical platform structure 135, both are frustum structures, and the structural dimensions of the conical inner concave cavity 134 correspond to the structural dimensions of the conical platform structure 135.

When the rotor rotates, due to the presence of the polygonal limiting rod 1411, the No. 1 externally threaded rod 146 and the No. 2 externally threaded rod 147 will rotate relative to each other. The externally threaded rod 147 produces the same rotation effect, thereby driving the No. 2 rotating shaft 139 to rotate in a certain direction, thereby producing the necessary linkage effect. When the size of the crushed particles needs to be adjusted, the threaded sleeve 141 is rotated in a certain direction. Since the spiral direction of the No. 1 threaded structure 144 is opposite to the spiral direction of the No. 2 threaded structure 145, and during the rotation process, the presence of the polygonal limiting rod 1411 prevents the No. 1 externally threaded rod 146 and the No. 2 externally threaded rod 147 from rotating relative to each other. Therefore, the distance between the No. 1 externally threaded rod 146 and the No. 2 externally threaded rod 147 will change, thereby changing the distance between the upper fixed disk 131 and the lower rotating disk 132, and thereby changing the size of the medicinal particles after crushing.

When the angle needs to be adjusted, the supporting link 10 is manually rotated. When the torque is greater than the maximum static friction force of the top locking rod 159 on the rotating disk 1510, the rotating disk 1510 will rotate accordingly until the equipment is at a suitable feeding angle. The rotation of the rotating disk 1510 can be stopped. At this time, due to the elastic function of the longitudinal coil spring 158, the top locking rod 159 will achieve a locking effect on the rotating disk 1510, thereby realizing the control function of the feeding angle.
