[0014] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiment is one embodiment of the present invention, not all embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] Unless otherwise defined, technical or scientific terms used in the present invention shall have the common meanings understood by one having ordinary skills in the field to which the present invention belongs.

[0016] This embodiment provides a salt pouring device, Reference Figure 1-Figure 3 A salt pouring device comprises a balance wheel 1, a swing rod 2, a clamping claw 3, a connecting plate 4 and a salt pouring driving assembly. The balance wheel 1 is rotatably connected to a base plate, and the salt pouring driving assembly is used to drive the balance wheel 1 to rotate along the base plate.

[0017] The pendulum rod 2 is arranged on the other side of the base plate and connected to the balance wheel 1, and rotates along the vertical direction with the balance wheel 1. The clamping jaw 3 is horizontally arranged at the end of the pendulum rod 2 away from the balance wheel 1, and is used to clamp the salt powder tube. When the balance wheel 1 rotates, the pendulum rod 2 and the clamping jaw 3 rotate together, and the salt powder tube clamped by the clamping jaw 3 performs a flipping and tilting motion, that is, the bottom of the tube flips upward, and the tube mouth flips downward.

[0018] The connecting plate 4 is a horizontally arranged L-shaped plate, one end of which is located on the same side of the base plate as the balance wheel 1 and is vertically slidably connected to the base plate, and a tension spring 5 is arranged at the vertical sliding connection, and the tension spring 5 is used to drive the connecting plate 4 to reset; a lever 11 is arranged at the edge of the balance wheel 1, and when the balance wheel 1 rotates, the lever 11 can drive the connecting plate 4 to slide vertically downward along the base plate; the other end of the connecting plate 4 extends to the other side of the base plate and is vertically provided with a funnel 41, which is arranged relative to the clamp 3 and is used to be inserted into the test tube when adding salt powder.

[0019] When adding salt, the salt powder tube with the cover opened is loaded into the clamping jaw 3, and then the salt pouring driving assembly drives the balance wheel 1 to rotate. When the balance wheel 1 rotates, the clamping jaw 3 drives the salt powder tube to flip, and at the same time, the funnel 41 slides vertically downward together with the connecting plate 4. When the balance wheel 1 rotates a certain angle, the salt powder tube is in a downward tilting state and the tube mouth is inserted into the funnel 41. The funnel 41 is also inserted into the test tube at this time, and the salt powder is poured into the test tube, completing the salt adding action; After the salting is completed, the balance wheel 1 rotates in the opposite direction to return to the initial state, at which time the clamping jaws 3 and the funnel 41 also return to the initial state, and the connecting plate 4 slides upward under the drive of the tension spring 5 and automatically resets to prepare for the next salting.

[0020] In order to prevent the salt powder from adhering to the wall of the salt powder tube or the inner wall of the funnel 41 during the salt adding process, a vibration motor 6 is provided on the swing rod 2 and the connecting plate 4. At the same time, in order to prevent the salt powder from vibrating and spilling into the environment during the salt adding process, an arc-shaped baffle 411 is also provided on the top of the funnel 41 along its circumferential direction.

[0021] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
