The lower end of the pipe joint 4 is detachably sleeved with a sampling pipe 5, the head of the sampling pipe 5 is larger than the aperture of the hole two 21, when the slide plate 2 moves downwards under the pushing of the screw rod, the slide plate 2 is propped against the head of the sampling pipe 5 and generates continuous downward pushing force, under the action of the pushing force, the sampling pipe 5 can be separated from the pipe joint 4 (in other embodiments, a suction nozzle 51 can be arranged, the outer diameter of the suction nozzle 51 is larger than the aperture of the hole two 21, the upper part of the suction nozzle 51 is detachably sleeved on the pipe joint 4, the lower part of the suction nozzle 51 is connected with the sampling pipe 5, and when the slide plate 2 moves downwards under the pushing of the screw rod, the slide plate 2 is propped against the suction nozzle 51 and generates continuous downward pushing force, and under the pushing force, the suction nozzle 51 can be separated from the pipe joint 4. Through the arrangement, after the sampling is completed, the sampling tube 5 and the sampling device can be driven to be separated only by rotating the screw 3, so that the damage of residual liquid to be sampled on the sampling tube 5 to the surrounding environment and operators is avoided.
Further, the base plate 1 is provided with four guide posts 6 downward for limiting the rotation of the slide plate 2, one end of each guide post 6 is fixed with the base plate 1, and the other end of each guide post penetrates through the slide plate 2. By providing the guide post, the movement of the slide plate 2 can be further restricted to the vertical direction, and the slide plate 2 is prevented from rotating.
In the embodiment, the sampler tube throwing device also comprises a tube placing tube 7 arranged below the sliding plate 2, and the sampling tube 5 is coiled and placed in the tube placing tube; the discharge tube 7 is provided with a release mechanism 71 triggered by rotation of the screw 3.

Specifically, the top end of the discharging tube 7 is opened, the bottom end of the discharging tube 7 is provided with a mechanism hole 711, the bottom end of the screw 3 penetrates out of the mechanism hole 711, the bottom end of the screw 3 is provided with a flange 712, the flange 712 is matched with the mechanism hole 711 in shape and is waist-shaped, when the flange 712 is dislocated with the mechanism hole 711, the flange 712 can upwards support the discharging tube 7, and when the flange 712 is aligned with the mechanism hole 711, the discharging tube 7 falls under the action of gravity, and meanwhile, the sampling tube 5 is scattered under the action of gravity. In order to prevent the discharging tube 7 from rotating along with the screw 3, a pair of limiting lugs 72 are arranged at the top of the discharging tube 7, and the bottom end of the guide post 6 penetrates into the limiting lugs 72, so that the discharging tube 7 can be limited to transversely rotate.
In this embodiment, the sampler tube-throwing device further includes a driver 8 for driving the screw 3 to rotate, and the driver 8 is fixed to the substrate 1. The driver 8 comprises at least two gears, wherein the driver 8 drives the screw 3 to rotate by an angle beta under one gear so that the flange 712 is aligned with the mechanism hole 711; the other lower driver 8 drives the sliding plate 2 to move downwards so that the sampling tube 5 is separated from the pipe joint 4 under the pushing action of the sliding plate 2. The drive 8 may be provided as a rotary motor, the output of which is connected to the screw 3 and can thus be used to drive the screw 3 in rotation. In the initial state, the flange 712 is staggered from the mechanism hole 711 by an included angle β (β is 90 °) and when the driver 8 is adjusted to the first gear, the driver 8 drives the screw 3 to rotate by the angle β so that the flange 712 is aligned with the mechanism hole 711, and the dispensing tube 7 falls under the action of gravity, and at the same time, the sampling tube 5 is scattered under the action of gravity. When the driver 8 is adjusted to another gear, the driver 8 drives the screw 3 to continuously rotate, and the slide plate 2 moves downwards under the pushing of the screw 3, so that the sampling tube 5 is separated from the pipe joint 4 under the pushing action of the slide plate 2. Specifically, the socket depth of the pipe joint 4 and the sampling pipe 5 is greater than the pitch x (β/360) of the screw 3. Since the screw 3 will rotate to drive the slide plate 2 to move down correspondingly when the driver 8 is adjusted to the first gear, in order to avoid the slide plate 2 pushing the sampling tube 5 to separate from the tube joint 4 during the process, the sleeve joint depth of the tube joint 4 and the sampling tube 5 is required to be larger than the pitch x (beta/360) of the screw 3, that is, even if the driver 8 is adjusted to the first gear, the screw 3 drives the slide plate 2 to move down, and the sampling tube 5 is not directly fallen off in the state.
While the invention has been described in terms of preferred embodiments, it is not intended to be limiting. Many possible variations and modifications of the disclosed technology can be made by anyone skilled in the art, or equivalent embodiments with equivalent variations can be made, without departing from the scope of the invention. Therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention shall fall within the scope of the technical solution of the present invention.
