When the main body needs to be sliced, weighed and screened, the main body is firstly placed in the driving box 2, then a signal is sent to a slicing device in the driving box 2 through the PLC, the main body is cut through the slicing device, so that the main body falls on the bearing plate 7, at the moment, one end, close to the bearing plate 7, of the transverse plate 5 moves towards the direction far away from the driving box 2 through the gravity of the main body, at the moment, because the transverse plate 5 is connected with the connecting plate 4 through the rotating rod 6, the rotating rod 6 is positioned in the middle of the transverse plate 5, the limiting of the transverse rod is realized through the rotating rod 6, at the moment, when one end of the transverse plate 5 moves towards the direction far away from the driving box 2, the other end of the transverse plate 5 moves towards the opposite direction, at the moment, the transverse plate 5 drives the positioning plate 8 to move, the positioning plate 8 drives the connecting rod 9 to move, the connecting rod 9 drives the bearing 10 to move, bearing 10 drive pointer 13 removes, bearing 10 drive stay cord 11 removes simultaneously, stay cord 11 drive balancing weight 12 removes, but here because stay cord 11 and pointer 13 all are connected with the outer lane of bearing 10, stay cord 11 passes through the gravity of balancing weight 12 self simultaneously, make stay cord 11 be in the state of straining all the time, make stay cord 11 be in the vertically state all the time with the axis of connecting rod 9 simultaneously, and make pointer 13 be in on the same axis all the time with stay cord 11, but here positioning disk 8 can be along with the swing of diaphragm 5 and remove during, so here through the swing of positioning disk 8 and the cooperation of pointer 13, realize weighing to the main part, the practicality of use has been improved.

Here, when the transverse plate 5 is far away from the end of the bearing tray 7 and moves towards the direction far away from the bottom end of the fixed box 1, the sliding block 14 on the transverse plate 5 is driven to move towards the direction far away from the sensor 24 in the limiting groove, at the moment, the spring 15 is in a stretching state, at the moment, the sensor 24 sends a signal to the PLC, at the moment, the PLC sends a signal to a driving device inside the driving box 2, through the matching of the driving device and the air pipe 3, the air outlet of the main body is realized, the main body drops in the collecting box 23 on the bottom end inside the fixed box 1, at the moment, the main body drops in different collecting boxes 23 through the difference of the distance that the sliding block 14 moves towards the sensor 24, the automatic screening of the main body is realized, and the screening quality is improved.

Here, through the slide bar 18 arranged in the limiting groove, the slide block 14 can slide more stably in the limiting groove, so that the sliding is prevented from shaking, the accuracy in screening is improved, and here, the distance sensor 24 is positioned through the adjusting component, so that the distance sensor 24 is prevented from moving.

When the main bodies with different weights need to be screened and the distance sensor 24 needs to be adjusted, only the rotary table 19 needs to be rotated, the rotary table 19 drives the telescopic rod 21 to move, the telescopic rod 21 drives the balls 22 to be in the positioning grooves, the telescopic rod 21 realizes the elastic fixation of the distance sensor 24, the damage to the distance sensor 24 caused by overlarge clamping force is prevented, meanwhile, the position limitation of the rotary table 19 is realized through the balls 22, the separation of the rotary table 19 and the distance sensor 24 is prevented, meanwhile, the rotary table 19 drives the screw rod 20 to rotate, so that the screw rod 20 is separated from the auxiliary groove on the sliding rod 18, at the same time, the movement of the distance sensor 24 can be realized, the contact area between the screw rod 20 and the sliding rod 18 is increased through the auxiliary groove, the fixing effect is improved, the use practicability is improved, the operation of the driving device is controlled through the PLC, so that the air pipe 3 blows the main bodies, the main body falls into the designated collecting box 23, intelligent screening is achieved, labor intensity of operators is reduced, and working efficiency is improved.

Compared with the prior art, the weighing and screening device for the herbal pieces realizes automatic weighing of the main body through the matching of the weighing mechanism and the adjusting mechanism, the cutting of the main body is realized through the slicing device in the driving box 2, so that the main body drops on the bearing tray 7, the prying of the transverse plate 5 is realized through the gravity of the main body at the moment, the operation of the sliding assembly is realized, the control of the swing angle of the transverse plate 5 is realized through the sliding assembly, then the gravity of the main body is determined through the scale on the positioning disc 8, the screening of the main bodies with different weights is realized through adjusting the distance between the distance sensor 24 and the sliding assembly, the practicability of the use is improved, the operation of the driving device is controlled through the PLC, the air blowing of the air pipe 3 to the main body is realized, the main body drops in the designated collecting box 23, and the intelligent screening is realized, the labor intensity of operators is reduced, and the working efficiency is improved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
