[0027] For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Examples, such as Figure 1-Figure 9As shown, a medicinal material picking soil screening device includes a first screening mechanism 100, which includes a screen drum 140 and brackets 110 arranged on both sides of the screen drum 140, a hollow rod 150 is fixedly connected to the middle of the screen drum 140, a rotating rod 160 is coaxially rotatably connected inside the hollow rod 150, a counterweight block 170 is connected to the side wall of the rotating rod 160, and a mounting block 120 is slidably connected to the two brackets 110, and the ends of the hollow rod 150 and the rotating rod 160 that are far away from each other are respectively rotatably connected to the mounting block 120, and a first spring 130 is connected between the upper and lower surfaces of the mounting block 120 and the bracket 110.

[0029] The working mechanism of the soil screening device provided in this embodiment is as follows: When in use, the medicinal materials are put into the sieve drum 140, and the two ends of the hollow rod 150 and the rotating rod 160 that are far away from each other are respectively connected to the motor through universal joints. When the motor is started, the hollow rod 150 and the rotating rod 160 are driven to rotate. The rotation speed of the hollow rod 150 is lower than the rotation speed of the rotating rod 160. When the hollow rod 150 rotates, the sieve drum 140 is driven to rotate, so that the medicinal materials in the sieve drum 140 are turned over. The rotation speed of the rotating rod 160 is fast, and since the counterweight block 170 is connected to the side wall of the rotating rod 160, radial runout can occur when the rotating rod 160 rotates. The force of the radial runout is transmitted to the first spring 130 through the mounting block 120, so that the mounting block 120 slides vertically back and forth, so that the sieve drum 140 vibrates radially and vertically, so that the soil adhered to the medicinal materials is vibrated and detached, and the detached soil falls through the pores on the sieve drum 140, completing the screening of the soil on the medicinal materials.

[0030] Among the optional methods of this embodiment, the more preferred ones are: A water tank 180 is disposed at the lower portion of the sieve drum 140 . A nozzle is connected to the water tank 180 and faces the sieve drum 140 .

[0031] A water pump is provided in the water tank 180, and two pipes are connected to the water pump. The water in the water tank 180 and a nozzle are connected through the two pipes respectively. The nozzle faces the sieve drum 140, and the nozzle flushes the medicinal materials in the sieve drum 140, so that the soil on the medicinal materials is further flushed and separated.

[0032] Regarding the structure of the second screening mechanism 200, specifically: The second screening mechanism 200 includes a mounting plate 210 connected to one of the brackets 110, the mounting plate 210 is located at the open end of the sieve drum 140, and a first conveyor belt 220 and a second conveyor belt 230 are vertically connected to the mounting plate 210. The first conveyor belt 220 and the second conveyor belt 230 are in contact with each other, and medicinal materials are clamped between the first conveyor belt 220 and the second conveyor belt 230. The first conveyor belt 220 and the second conveyor belt 230 rotate synchronously and in opposite directions to transport the medicinal materials to the sieve drum 140.

[0033] The length of the first conveyor belt 220 is shorter than that of the second conveyor belt 230 . The medicinal materials are placed between the first conveyor belt 220 and the second conveyor belt 230 . The two conveyor belts rotate synchronously and in opposite directions, so that the medicinal materials are conveyed into the sieve drum 140 .

[0034] Among the optional methods of this embodiment, the more preferred ones are: The second screening mechanism 200 also includes a baffle 240. The conveying surfaces of the first conveyor belt 220 and the second conveyor belt 230 are both inclined toward the screen drum 140. The baffle 240 is fixedly connected to the mounting plate 210. The mounting plate 210 is in contact with the sides of the first conveyor belt 220 and the second conveyor belt 230. A discharge port 250 is provided on the baffle 240, and the discharge port 250 faces the screen drum 140.

[0035] The baffle 240 blocks the medicinal materials so that they will not fall before they move to the end of the sieve drum 140. The end of the first conveyor belt 220 does not extend to the discharge port 250, so that when the medicinal materials move to the discharge port 250, the upper part is not pressed down by the first conveyor belt 220 but slides into the sieve drum 140 through the discharge port 250 due to gravity.

[0036] Among the optional methods of this embodiment, the more preferred ones are: The second screening mechanism 200 also includes a clamping jaw 260, on which two groups of rollers 261 are symmetrically arranged, and the two groups of rollers 261 are respectively attached to the first conveyor belt 220 and the second conveyor belt 230, and the clamping jaw 260 is connected with a sliding column 262, and the baffle 240 is provided with a hole that cooperates with the sliding column 262, and a second spring 263 is connected between the sliding column 262 and the baffle 240. When the clamping jaw 260 slides back and forth, the first conveyor belt 220 and the second conveyor belt 230 vibrate to shake off the soil at the roots of the medicinal materials.

[0037] When the medicinal materials are placed between the first conveyor belt 220 and the second conveyor belt 230, the upper part of the medicinal materials is squeezed and clamped, and the roots are exposed to the outside. The clamping jaws 260 slide back and forth on the baffle 240, so that the two conveyor belts are driven to vibrate, so that the large pieces of soil adhering to the roots of the medicinal materials are vibrated and fall off. The setting of the rollers 261 ensures that the operation of the two conveyor belts is not interfered by large friction.

[0038] Among the optional methods of this embodiment, the more preferred ones are: The second screening mechanism 200 also includes a piston assembly 280 and a cylinder 290. The piston assembly 280 is connected between one of the mounting blocks 120 and the bracket 110. A push rod 293 is slidably connected in the cylinder 290. A tension spring 291 is connected between the push rod 293 and the cylinder 290. A convex plate 264 is provided on the clamping jaw 260, and the top of the push rod 293 abuts against the convex plate 264. A through hole 292 is opened on the side wall of the cylinder 290, and an air outlet pipe 281 is connected between the piston assembly 280 and the cylinder 290. When the mounting block 120 slides, the piston assembly 280 injects air into the cylinder 290, so that the push rod 293 pushes the clamping jaw 260 to move back and forth.

[0039] The piston cylinder and piston rod of the piston assembly 280 are respectively connected to the bracket 110 and the mounting block 120. When the mounting block 120 slides up and down, the piston rod can be driven to slide back and forth in the piston cylinder. An air inlet pipe (not shown in the figure) is also connected to the piston cylinder. Both the air inlet pipe and the air outlet pipe 281 are provided with a one-way valve, so that air can be continuously injected into the cylinder 290 when the mounting block 120 slides back and forth. The inner diameter of the piston cylinder is larger than the cylinder 290, so that the air lifts the push rod 293 to move upward. After the push rod 293 moves upward, the clamping jaw 260 is lifted up through the convex plate 264. When the push rod 293 moves up to the upper position of the through hole 292, the air in the cylinder 290 is discharged, and at the same time, the pulling force of the tension spring 291 is cooperated to make the push rod 293 slide down. When the push rod 293 slides down, the second spring 263 drives the clamping jaw 260 to move back and forth, thereby causing the clamping jaw 260 to vibrate.

[0040] Regarding the structure of the support mechanism 300, specifically: The supporting mechanism 300 includes a base 310 , a support rod 270 is connected to the base 310 , and a cylinder 290 is connected to the top of the support rod 270 .

[0041] The arrangement of the support rod 270 raises the height of the cylinder 290 so that the top rod 293 can contact the convex plate 264 .

[0042] Among the optional methods of this embodiment, the more preferred ones are: The support mechanism 300 also includes a swing seat 320, which is hinged to the base 310, and the bracket 110 is fixedly connected to the swing seat 320. Two sets of cams 370 are symmetrically rotatably connected on both sides of the swing seat 320. The two sets of cams 370 are oriented in opposite directions. When the two sets of cams 370 rotate one hundred and eighty degrees, the opening of the screen drum 140 is inclined upward or downward; when the opening of the screen drum 140 is inclined downward, the push rod 293 is out of contact with the convex plate 264.

[0043] The setting of the swing seat 320 allows the sieve drum 140 to be installed. The swing seat 320 can swing relative to the base 310, so that the opening of the sieve drum 140 can be inclined upward or downward. When the soil is screened for medicinal materials, the opening of the sieve drum 140 is inclined upward to ensure that the medicinal materials will not easily escape from the sieve drum 140. When the medicinal materials are discharged after the soil is screened, the opening of the sieve drum 140 is inclined downward to allow the medicinal materials to be discharged. In addition, since the support rod 270 is connected to the base 310 and the bracket 110 is connected to the swing seat 320, when the swing seat 320 swings, the top rod 293 can contact or separate from the convex plate 264, so that when the soil on the medicinal materials is screened, the two screening mechanisms can operate simultaneously, and when the medicinal materials are discharged, only the first screening mechanism 100 operates, thereby reducing the energy consumption when the medicinal materials are discharged, and at the same time, the two screening mechanisms can operate synchronously when screening the soil of the medicinal materials.

[0044] Among the optional methods of this embodiment, the more preferred ones are: A rack 340 is slidably connected in the swing seat 320 , two shafts 350 are rotatably connected in the swing seat 320 , a cam 370 is connected to the ends of the shafts 350 , and a gear 360 meshing with the rack 340 is fixedly connected to the middle of the shaft 350 .

[0045] The two groups of cams 370 contact the base 310 asynchronously to ensure that the swing seat 320 can be driven by the cam 370 to swing. When the rack 340 slides, it can drive the gear 360 to rotate, thereby rotating the shaft 350, rotating the cam 370, and then causing the swing seat 320 to swing.

[0046] Among the optional methods of this embodiment, the more preferred ones are: The support 110 is connected to a cylinder 330 , and an output end of the cylinder 330 is connected to a rack 340 .

[0047] The cylinder 330 can drive the rack 340 to slide back and forth, thereby changing the tilt angle of the swing seat 320.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
