Description

Technical Field

[0001] The present invention relates to the technical field of Salvia miltiorrhiza processing and screening equipment, and particularly relates to a roll-type Salvia miltiorrhiza grading and selecting equipment. Background Art

[0002] Salvia miltiorrhiza is a perennial upright herb of the Labiatae family and the Salvia genus. The roots of Salvia miltiorrhiza can be used as medicine, containing tanshinone, which is a tonic emmenagogue and has effects such as dispelling stasis, generating new, promoting blood circulation, and regulating menstruation. The medicinal value of the roots of Salvia miltiorrhiza is relatively high. The diameter of the roots of Salvia miltiorrhiza is 5 - 22 mm. The steps for processing the roots of Salvia miltiorrhiza are: drying - removing the rhizome tip - sieving soil - removing root hairs - classifying and placing. The existing processing of Salvia miltiorrhiza is manual processing, with low processing efficiency and waste of manpower and material resources. Especially when classifying and grading Salvia miltiorrhiza according to the diameter of the roots, even when manually selecting, there are often mixed situations, resulting in uneven classification of Salvia miltiorrhiza. Therefore, there is an urgent need to design a roll-type Salvia miltiorrhiza grading and selecting equipment to solve the problems of low efficiency of existing manual processing of Salvia miltiorrhiza and uneven classification. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a roll-type Salvia miltiorrhiza grading and selecting equipment.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a roll-type Salvia miltiorrhiza grading and selecting equipment, including a rhizome tip shearing mechanism, a vibrating sieve mechanism, and a roll sorting area. The rhizome tip shearing mechanism is provided with a Salvia miltiorrhiza conveyor belt and a cutter. The Salvia miltiorrhiza is placed flat on the Salvia miltiorrhiza conveyor belt, with the rhizome tip end of the Salvia miltiorrhiza facing the cutter. The cutter integrally shears the rhizome tip of the Salvia miltiorrhiza, and the Salvia miltiorrhiza conveyor belt transports the Salvia miltiorrhiza to the vibrating sieve mechanism, and the vibrating sieve mechanism removes the soil and impurities on the Salvia miltiorrhiza;

[0005] The roll sorting area includes a root hair shearing mechanism and a grading and blanking mechanism. The root hair shearing mechanism is provided with a cutter roller that receives the Salvia miltiorrhiza dropped by the vibrating sieve mechanism. The cutter roller transports the Salvia miltiorrhiza and wears down the root hairs of the Salvia miltiorrhiza. The cutter roller transports the Salvia miltiorrhiza to the transmission rollers of the grading and blanking mechanism. The gap sizes between the transmission rollers are different, and are used for the Salvia miltiorrhiza to be automatically graded and blanked according to the diameter.

[0006] Specifically, the Salvia miltiorrhiza conveyor belt is installed on a shearing base through a bracket. The Salvia miltiorrhiza conveyor belt is supported and connected by a driving roller shaft and a driven roller shaft. The driving roller shaft is connected to a conveyor belt motor, and the conveyor belt motor drives the Salvia miltiorrhiza conveyor belt to rotate. A number of partitions are evenly installed on the Salvia miltiorrhiza conveyor belt. The Salvia miltiorrhiza is placed in the cavity formed by the partitions. A soft baffle is provided between the partitions and on the side away from the cutter, and the soft baffle blocks one end of the Salvia miltiorrhiza.

[0007] Specifically, the cutter is installed on the cylinder rod of a cutter cylinder. The cylinder body of the cutter cylinder is fixed on a cutter frame. A cutting plate is fixed below the cutter, and the rhizome tip part of the Salvia miltiorrhiza is located between the cutter and the cutting plate.

[0008] Specifically, the vibrating sieve mechanism includes a sieve mesh, vibrating motors, a sieve mesh discharge baffle, and a material pushing rod. The sieve mesh is inclined downward from the lateral root hair shearing mechanism of the reed head. The four corners of the sieve mesh are connected to vibrating springs, and the vibrating springs are installed on the sieve mesh frame. The bottom of the sieve mesh frame is fixed on the vibrating sieve base. Vibrating motors are installed on both sides of the sieve mesh, and the vibrating motors control the vibration of the sieve mesh.

[0009] Specifically, a sieve mesh discharge baffle is installed at the discharge opening of the sieve mesh. The bottoms on both sides of the sieve mesh discharge baffle are installed on the piston rods of lifting cylinders. The cylinder bodies of the lifting cylinders are installed on the vibrating sieve base through brackets. The lifting cylinders control the sieve mesh discharge baffle to descend and block at the discharge opening of the sieve mesh. A laterally moving material pushing rod is provided on the sieve mesh discharge baffle, and the laterally moving material pushing rod pushes the salvia miltiorrhiza into a lateral setting.

[0010] Specifically, a lead screw is provided inside the sieve mesh discharge baffle. The lead screw is rotatably installed inside the sieve mesh discharge baffle through two bearing seats. One end of the lead screw is connected to a material pushing motor through two bevel gears. The material pushing motor drives the lead screw to rotate. A lead screw nut seat is threadedly connected to the lead screw, and the lead screw nut seat is connected to the material pushing rod. The material pushing rod adopts an "L" - shaped structure, and the material pushing rod extends out of the strip - shaped hole on the sieve mesh discharge baffle.

[0011] Specifically, a sieve mesh discharge slide plate is also connected at the discharge opening of the sieve mesh. When the lifting cylinder controls the sieve mesh discharge baffle to rise, the salvia miltiorrhiza falls onto the knife roller through the sieve mesh discharge slide plate.

[0012] Specifically, multiple knife rollers are provided. The knife rollers are rotatably installed on the root hair shearing roller frame.

Scraping knives are provided on the surfaces of the knife rollers.

[0013] Specifically, multiple transmission rollers are provided. The transmission rollers are installed on the transmission roller frame. The transmission rollers are connected to a transmission roller motor through a transmission chain. The transmission roller motor drives the transmission rollers to rotate simultaneously in the same direction. Different - sized roller gaps are provided between the transmission rollers. The roller gap sizes are set to 5mm, 7mm, 12mm, 17mm, 22mm. Receiving boxes are placed below the roller gaps, and the receiving boxes receive the salvia miltiorrhiza corresponding to the roller gap sizes that fall.

[0014] A working method of a roller - type salvia miltiorrhiza grading and selecting device includes the following steps:

[0015] 1) First, the salvia miltiorrhiza is dried in a drying room, and the moisture content of the salvia miltiorrhiza is controlled to be 40% - 60%, and the salvia miltiorrhiza roots are in a soft and spongy state;

[0016] 2) After drying, the salvia miltiorrhiza is placed between the partitions of the salvia miltiorrhiza conveyor belt. The salvia miltiorrhiza is placed with its root tip against the soft baffle and its rhizome facing the cutter. The conveyor belt motor drives the salvia miltiorrhiza conveyor belt to move slowly. When the number of salvia miltiorrhiza fills the cutting range of the cutter, the cutter cylinder is controlled to descend through the remote control, and the cutter and the cutting plate cooperate to cut off the rhizome.

[0017] 3) The cut salvia miltiorrhiza continues to move through the salvia miltiorrhiza conveyor belt and falls onto the sieve mesh. The vibration motor drives the sieve mesh to vibrate, shaking off the soil and sundries on the salvia miltiorrhiza, and the salvia miltiorrhiza gradually moves to the discharge opening of the sieve mesh.

[0018] 4) The lifting cylinder drives the discharge baffle of the sieve mesh to descend to block the discharge opening of the sieve mesh. The feeding motor drives the feeding rod to move horizontally, and the salvia miltiorrhiza attached to the discharge baffle of the sieve mesh is dialed horizontally. The lifting cylinder drives the discharge baffle of the sieve mesh to rise, and the horizontally dialed salvia miltiorrhiza slides down through the discharge slide plate of the sieve mesh onto the cutter roller.

[0019] 5) The cutter roller rotates to convey the salvia miltiorrhiza and wears off the root hairs on the surface of the salvia miltiorrhiza.

[0020] 6) The cutter roller conveys the salvia miltiorrhiza to the transmission roller. The salvia miltiorrhiza with a diameter less than 5 mm falls into the receiving box through the gap between the first transmission roller and the second transmission roller. The salvia miltiorrhiza with a diameter of 5 - 7 mm falls into the receiving box through the gap between the second transmission roller and the third transmission roller. The salvia miltiorrhiza with a diameter of 7 - 12 mm falls into the receiving box through the gap between the third transmission roller and the fourth transmission roller. The salvia miltiorrhiza with a diameter of 12 - 17 mm falls into the receiving box through the gap between the fourth transmission roller and the fifth transmission roller. The salvia miltiorrhiza with a diameter of 17 - 22 mm falls into the receiving box through the gap between the fifth transmission roller and the sixth transmission roller. The salvia miltiorrhiza with a diameter greater than 22 mm falls into the receiving box behind the sixth transmission roller.

[0021] The present invention has the following beneficial effects:

[0022] The roller - type salvia miltiorrhiza grading and selection equipment designed by the present invention uses automated steps to remove the rhizome - sieve soil - remove root hairs - classify and place the salvia miltiorrhiza, realizing automated operation, reducing production costs, and improving production efficiency; and through the size of the gaps between the transmission rollers, automatic grading and classification of the salvia miltiorrhiza are realized, and the salvia miltiorrhiza vibrates and falls according to its diameter size, making the grading and classification of the salvia miltiorrhiza more uniform.
