Description
Technical Field
[0001] The utility model relates to the technical field of screening Chinese herbal medicine slices, in particular to a screening machine for processing Chinese herbal medicine slices. Background Art
[0002] Most of the raw materials used to process Chinese herbal medicines carry a lot of impurities. When we obtain Chinese medicine, we need to remove the impurities through a screening machine. However, after the screening machine has been used for a long time, a large amount of impurities will remain on the screen, which reduces the screening efficiency. In addition, due to the presence of impurities, the screening machine is blocked, making it difficult to discharge the material. Therefore, in order to ensure the screening efficiency of the screening machine, the screen needs to be cleaned frequently, but the cleaning process is time-consuming and laborious. Summary of the invention
[0003] The utility model aims to provide a screening machine for processing Chinese herbal medicine slices, which can thoroughly clean the sieve holes and ensure the screening efficiency, in view of the above problems.
[0004] To achieve the above-mentioned purpose, the utility model discloses a screening machine for processing Chinese herbal medicine slices, comprising a circular screening barrel, wherein a circular sieve plate arranged horizontally is movable in the screening barrel. A vibration motor located below the sieve plate is fixedly installed on the inner wall of the screening barrel, and the output end of the vibration motor is connected to the bottom of the sieve plate. A cleaning brush with bristles arranged downward is arranged above the sieve plate, and the bottom of the bristles of the cleaning brush abuts against the sieve plate. The cleaning brush is fixedly connected to a rotating rod arranged coaxially with the screening barrel, and the rotating rod is rotatably installed in the screening barrel. An impurity cleaning port is opened on the screening barrel, and an arc-shaped door adapted to the wall of the screening barrel is arranged on the impurity cleaning port. A cleaning brush is arranged above the sieve plate. When there are many impurities on the sieve plate that need to be cleaned, the rotating rod rotates to drive the cleaning brush to rotate on the sieve plate, and then the upper surface of the sieve plate is cleaned, and the cleaning work is simple; because the bristles are relatively soft, the sieve plate can be cleaned more thoroughly, and the impurities on the sieve plate will not be squeezed into the sieve holes of the sieve plate, and the cleaning is thorough, which ensures the screening efficiency.
[0005] Preferably, the top wall of the screening barrel bulges upward to form a conical protective shell that is small at the top and large at the bottom. The top opening of the protective shell forms a feed inlet, and the bottom opening is connected to the interior of the screening barrel.
[0006] Preferably, a rotating motor is fixedly mounted on the top wall of the screening barrel, and the output shaft of the rotating motor is fixedly connected to the upper end of the rotating rod.
[0007] Preferably, the outer fixed sleeve of the rotating motor is provided with a motor cover, the bottom of the motor cover is provided with a through hole through which the output shaft of the rotating motor can pass, the motor cover is located inside the protective shell, and is connected to the top wall of the screening barrel through a plurality of fixing rods. The motor is arranged in the protective shell, and the top of the protective shell is the feed port, which makes full use of the top space of the screening barrel and has a simple structural design.
[0008] Preferably, the top wall of the motor cover is arranged lower than the feed port, so that the overall appearance of the screening machine looks simpler; and the top wall and the side wall of the motor cover have an arc transition, and a feed channel is formed between the motor cover and the protective shell, so that Chinese medicinal materials can easily enter the screening barrel from the feed channel.
[0009] Preferably, a plurality of cleaning brushes are arranged at equal intervals, and the cleaning brushes are arranged in an arc from the rotating rod toward the side wall of the screening barrel, and one end of the cleaning brushes close to the side wall of the screening barrel is bent toward the side opposite to the rotation direction of the rotating rod. The cleaning brush is arranged in an arc shape, so that during cleaning, the impurities on the screen plate can be easily cleaned to the side wall of the screening barrel by the centrifugal effect of the cleaning brush when it rotates, and the impurities are then cleaned out of the screen plate through the impurity cleaning port.
[0010] Preferably, a vertically arranged column is fixed in the middle of the upper surface of the sieve plate, a cylindrical limiting groove extending downward is provided on the upper surface of the column, and the lower part of the rotating rod is movably arranged in the limiting groove. When the sieve plate vibrates under the action of the vibration motor, since the limiting groove provided on the column is sleeved outside the rotating rod, the sieve plate can only vibrate with a limited amplitude under the action of the column, thereby ensuring the stability of the sieve plate during vibration. In addition, due to the provision of the column, impurities can be prevented from accumulating on the end of the cleaning brush close to the rotating rod, further ensuring the thoroughness of impurity cleaning.
[0011] Preferably, a support ring is provided below the sieve plate, an outer ring of the support ring is fixedly connected to the inner wall of the screening barrel, and the sieve plate is movably placed on the support ring.
[0012] Preferably, a conical slideway with a larger upper part and a smaller lower part is provided below the support ring, a discharge port is provided on the bottom wall of the screening barrel, and the bottom of the slideway is connected to the discharge port, so that the Chinese medicine passing through the sieve plate can be discharged from the discharge port.
[0013] Preferably, a receiving tray is provided below the screening barrel, and two vertical legs are symmetrically provided on the bottom wall of the screening barrel along the front-rear direction, and the receiving tray is movably arranged between the two legs. The structural design of the legs is simple while ensuring structural stability.
[0014] In summary, the beneficial effects of the utility model are: the utility model has a simple structural design, a cleaning brush is arranged above the sieve plate, and the cleaning brush rotates to clean the sieve plate, which saves time and effort, and cleans thoroughly, thereby ensuring the screening efficiency.
