The four medicine tubes 1 are horizontally arranged and are positioned at the same height together, the bottoms of the four medicine tubes 1 are provided with supporting legs 6, and the four supporting legs 6 are provided with positioning holes; the four medicine tubes 1 are supported by the supporting legs 6, and the device is installed on the equipment to be dosed when in use, and the bolts penetrate through the positioning holes on the supporting legs 6 to be connected with the equipment to be dosed.

One side of one end of each of the four medicine pipes 1 is provided with a medicine inlet hole 7 in a penetrating way, the middle part of one side of each of the four medicine pipes 1 is provided with a medicine outlet hole 8 in a penetrating way, and check valves 9 are arranged on the medicine inlet holes 7 and the medicine outlet holes 8; the medicine inlet holes 7 are respectively connected with the medicine storage tank, the medicine outlet holes 8 are connected with medicine holes on the equipment to be added with medicine, and the preparation operation is finished.

A driving shaft 10 is arranged in the middle of the bottom end of the driving disc 4, and the driving shaft 10 is connected with an output shaft of the driving device; the driving device is controlled to work, and the output shaft of the driving device drives the driving disc 4 to rotate through the driving shaft 10.

The middle part of the driving disc 4 is embedded with a bearing 12, and the middle part of one side of the carrier 31 is fixedly connected with the inner ring of the bearing 12; since the carrier 31 of the restraint assembly 3 is connected to the drive disk 4 via the bearing 12, the carrier 12 is held stationary while the drive disk 4 is rotating.

The middle part of one end of each of the four pistons 2 is rotationally embedded with a pulley 11, and the thickness of each of the four pulleys 11 is consistent with that of the driving disc 4; because the piston 2 contacts with the outer edge of the driving disc 4 through the pulley 11, the driving disc 4 expands two groups of pistons 2 which are arranged in a staggered way one by one along with the rotation of the driving disc 4, and the pistons extend into the medicine tube 1 which is matched with the pistons.

The restraint assembly 3 comprises a carrier 31, a chute 32 is concavely formed in one side of the carrier 31, elastic pieces 33 and connecting rods 34 are arranged in the four chute 32, two ends of the elastic pieces 33 are respectively connected with the inner wall of the chute 32 and one end of each connecting rod 34, and the four connecting rods 34 respectively extend to one ends of the four pistons 2 and are fixedly connected with the four pistons; because the piston 2 is connected with the restraint subassembly 3 for when the driving disk 4 is rotatory, the pulley 11 of piston 2 one end all can contact with the outer edge of driving disk 4, and the principle is: as shown in fig. 1 or fig. 2, when the widest points of the two ends of the driving disc 4 are aligned with one set of symmetrical pistons 2 (labeled as "1 set" and the other set as "2 set"), the pistons 2 of the 1 set extend into the medicine tubes 1 at the two sides to the maximum length respectively, meanwhile, the connecting rod 34 connected with the pistons 2 moves in the sliding groove 32 in the process of extending the pistons 2 into the medicine tubes 1, and the connecting rod 34 is connected with the elastic piece 33, so that the elastic piece 33 stretched in the process of moving the connecting rod 34 deforms, when the widest points of the two ends of the driving disc 4 rotate to be aligned with the pistons 2 of the 2 set, the elastic piece 33 connected with the pistons 2 of the 1 set slowly contracts and returns to the initial state when no external force expands, and the pulley 11 on the pistons 2 is driven to contact with the outer edge of the rotating driving disc 4 all the time, thereby generating the phenomena that the pistons 2 of the 1 set extend into the medicine tubes 1 and the pistons 2 of the 2 set contract into the medicine tubes 1; when the pistons 2 of the group 1 extend, the medicine outlet holes 8 are covered, so that medicine adding work is not performed, and when the pistons 2 of the group 2 shrink, the medicine outlet holes 8 are not covered, so that medicine adding work is performed; note that the above-described dosing is performed with the check valves 9 on the medicine inlet hole 7 and the medicine outlet hole 8 in an open state.

Two of the sliding grooves 32 are symmetrically arranged, and the other two sliding grooves 32 are arranged between the two symmetrically arranged sliding grooves 32; the reason why the plurality of sliding grooves 32 are arranged as shown in the second embodiment is to ensure that the driving disk 4 does not block the movement of the piston 2 when driving the piston 2 to move, so as to fully utilize the space between the pistons 2; the elastic member 33 is a rubber strip or a spring, and the elastic member 33 may be a member which can be restored to the original state as long as the elastic member 33 is stretched from the state without an external force after stretching, and is preferably an elastic stopper conventionally used for rubber strips or springs.

The plurality of convex columns 5 are 3-5 cm, and threads are arranged outside the plurality of convex columns 5; because the stroke of the movement of the piston 2 is consistent, if the throwing proportion of two reagents is required to be changed, the piston 2 with the same length can be adjusted by arranging gaskets with different thicknesses on one end of the piston, the process is that the gaskets are sleeved on the convex column 5 at one end of the piston 2, the gaskets are locked by nuts, and the added gaskets are increased or decreased according to actual use.
