Detailed Description

The utility model provides a powder material sampler.

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings to better understand the present invention, but the following embodiments do not limit the scope of the present invention.

Referring to fig. 1, the utility model provides a powder material sampler, which comprises a barrel 1, a sampling cavity 6 arranged in the barrel for storing powder material samples, a chute 4 and a rotating shaft arranged above the sampling cavity; a slide block 5 which is sleeved on the rotating shaft and can slide up and down along the slide groove 4 is arranged in the slide groove 4;

a handle 2 is arranged outside the upper end of the cylinder body 1; a screw rod 7 is arranged in the sampling cavity 6, and continuous threads 8 are arranged on the screw rod 7; the screw rod 7, the rotating shaft and the handle 2 are integrally connected.

Handle 2, axis of rotation and hob 7 connect fixed structure as an organic whole, and the mode of connection is selected from modes such as welded fastening, fix with screw, but not limited to this, does not influence the technical scheme of the utility model.

A bearing 3 is fixed in the sliding block 5, the rotating shaft is fixed on the inner ring of the bearing 3, the outer ring of the bearing 3 is in interference fit with the sliding block 5, the inner ring of the bearing 3 is in interference fit with the rotating shaft, and the diameter of the sliding block 5 is smaller than that of the sliding chute 4; the rotating shaft and the inner ring of the bearing 3 are fastened, the outer ring of the bearing 3 and the sliding block 5 are fastened, the rotating shaft and the sliding block 5 can rotate relatively, and the sliding block 5 can freely interact up and down along the sliding groove 4.

As shown in fig. 2, a bottom cover 9 is arranged at one end of the barrel 1 away from the handle 2, so as to prevent the powder material from falling from the bottom end of the barrel 1 after the powder material is completely taken, the bottom cover 9 is divided into 3-9 fan-shaped parts on average and is respectively connected with the barrel wall of the barrel 1 through a spring 10, when the bottom cover 9 is not used, the bottom cover is in a closed state due to the elasticity of the spring 10 and is pushed open by the screw rod 7 in the using process, when the screw rod 7 is retracted to the sampling cavity 6, the bottom cover 9 is automatically closed under the elasticity of the spring 10, so as to prevent the powder material from falling from the sampling cavity; the radius of the bottom cap 9 is greater than the distance between two adjacent protrusions on the thread 8, preventing the bottom cap from being jammed in the thread 8 due to the elastic force of the spring 10 when the bottom cap is opened.

The utility model provides a powder material sampler use method is, hold the handle 2 at first and promote downwards along barrel 1, because there is certain clearance between outer lane and the inner circle of bearing 3, can not receive the pressure of the air in the spout 4 and lead to being difficult to promote handle 2 in the course of promoting; the handle 2 is pushed to enable the sliding block 5 to slide downwards along the sliding groove 4, the screw rod 7 moves downwards along with the sliding block, and the bottom cover 9 is jacked open; then the sampler is inserted into the powder material, and the tip end of the bottom cover 9 is beneficial to the sampler to be inserted into the powder material more easily because of the plurality of fan shapes; the handle 2 is rotated to drive the screw rod 7 to rotate relative to the cylinder 1, powder materials are conveyed and carried into the sampling cavity 6, and if excessive samples are taken, the handle 2 can be rotated reversely to discharge redundant powder materials into the reaction kettle; finally, holding handle 2 and upwards pulling along barrel 1, slider 5 upwards slides along spout 4, and the hob 7 is whole to get back to the sample intracavity, because spring 10's elasticity, each fan-shaped bottom of bottom 9 can fold automatically under the effect of elasticity and close, prevents that the powder material from dropping from sampling 6 in the chamber.

Because the utility model provides a powder material sampler sample is for detecting or experiment, only need when taking a sample to the powder material get less partly can.
