Detailed Description

The first embodiment is as follows: a sampler of the present embodiment, as shown in fig. 1 and 2, includes a sampling tube 1, a check plate 2, and a stopper 3;

the sampling tube 1 is a hollow square tube, one end of the sampling tube 1 is a sampling end, and the other end of the sampling tube 1 is a discharging end;

a notch is arranged on one side of the sampling end port, so that the sampling end port is pointed;

the check plate 2 is positioned in the sampling tube 1 and is close to the sampling end, the check plate 2 is adapted to the cross section of the sampling tube 1, and the sampling tube 1 can be plugged when the check plate 2 is parallel to the cross section of the sampling tube 1;

one edge of the check plate 2 is hinged with one inner wall of the sampling tube 1;

spacing portion 3 is fixed in on the 1 inner wall of sampling tube between 1 port of sampling tube and check plate 2, and the inner wall that spacing portion 3 was fixed and the articulated inner wall of check plate 2 are different inner walls, and spacing portion 3 blocks that check plate 2 overturns towards sample end one side for can be on a parallel with the cross section of sampling tube 1 when check plate 2 is blockked by spacing portion 3.

In particular, the use method of the sampler of the embodiment is that an operator holds the position close to the discharge end by hand, places the sampler above the material (grain, small particles or powder) to be sampled and then inserts the sampler into the material, because the check plate 2 is hinged with one inner wall of the sampling tube 1, when the material is inserted downwards, the thrust of the material to the check plate 2 can make the check plate 2 overturn towards the direction back to the sampling end, the material can be pushed during insertion of the sampling tube 1 and pass the check plate 2 into the sampling tube 1, when a proper amount of material is obtained, the sampling tube 1 is pulled out, the check plate 2 is overturned towards one side of the sampling end under the action of gravity and the pressure of the material, however, because of the limiting part 3, the check plate 2 can only be turned to a position parallel to the cross section of the sampling tube 1 to block the sampling tube 1, so that the sampled material is left in the sampling tube 1.

When the material of sample need be taken out, overturn the sampler, make the discharge end down, pour the material.

This novel sampler is when using, according to the granularity size of being got the thing material and the degree of depth needs of material, sampler length and thickness can design for several different models, and the sampler of the thick little of selection of material granularity is big, and the material packing is big, can select sampler etc. of a little on long side.

The most preferred embodiment is as follows: in this embodiment, the first embodiment is further described, as shown in fig. 4, in this embodiment, the sampler further includes an auxiliary handle 4;

the auxiliary handle 4 is a circular tube with two open ends, and one end of the auxiliary handle 4 is communicated with the discharging end.

Specifically, since the tube body of the sampling tube 1 is a square tube and may exceed the palm holding range, a circular tube-shaped auxiliary grip 4 may be added, the auxiliary grip 4 should be able to be held by a single hand, and the outer surface of the auxiliary grip 4 may be further provided with friction lines to increase the friction force during holding.

Because the auxiliary handle 4 is changed phase to extend the length of the sampling tube 1, the sampler in this embodiment pours the material from the other end of the auxiliary handle 4 through the discharging end after sampling.

The outer surfaces of two sides of the other end of the auxiliary handle 4 are symmetrically fixed with cross rods 15 to form a T-shaped structure with the auxiliary handle 4, firstly, when sampling is carried out, materials have certain density, so that the sampling cannot be pressed in by only depending on the self weight of the sampling tube 1, and the T-shaped structure is convenient for operators to press down with palms to apply force; secondly, prevent that sampling tube 1 from because overweight makes the sampler slippage from operating personnel hand after the sample to can conveniently pull out after the sample, when the sampler is small-size, can even singlehanded operation.

The most preferred embodiment is as follows: in this embodiment, as shown in fig. 5, the sampler further includes a quantitative output mechanism 6, a quantitative adjusting button 7, a feeding baffle 13, and a discharging baffle 8;

the quantitative output mechanism 6 is positioned at the discharge end, the quantitative output mechanism 6 is cylindrical, a plurality of metering grooves 9 with equal capacity are arranged on the side surface of the quantitative output mechanism 6, and as shown in fig. 6, the metering grooves 9 are uniformly distributed along the circumferential direction of the bottom surface of the quantitative output mechanism 6;

a rotating shaft is fixed at the axis of the quantitative output mechanism 6, and the quantitative output mechanism 6 is rotationally matched between the two opposite inner walls of the sampling tube 1 through the rotating shaft;

the quantitative adjusting button 7 is positioned outside the sampling tube 1, and one end of the rotating shaft passes through the side wall of the sampling tube 1 and is fixed with the quantitative adjusting button 7;

the feeding baffle 13 is fixed inside the sampling tube 1 and is positioned at the feeding side of the quantitative output mechanism 6, a feeding port 14 which is less than or equal to the notch of the metering tank 9 is arranged on the feeding baffle 13, and the feeding port 14 is positioned right above the quantitative output mechanism 6;

the discharge baffle 8 is fixed in the sampling tube 1, and is located the discharge side of the quantitative output mechanism 6, and the discharge baffle 8 is provided with a discharge hole 10 which is less than or equal to the notch of the metering tank 9.

Specifically, when the material is discharged, certain requirements may be imposed on the volume and the weight, so that the quantitative output mechanism 6 is added for measurement, the measurement is applicable to the measurement, the condition of sufficient accuracy is not required, the measurement groove 9 may be a unit capacity, such as 1ml, and the weight may be calculated by obtaining the average density of the sampled material in advance.

The diameter of the bottom surface of the cylinder of the quantitative output mechanism 6 and the height of the cylinder can be just matched with the inner wall of the sampling tube 1, and the gap can be sealed by rubber. Like this, invert the sampler (the sample end is upwards, and the discharge end is downward) after the material sample, the material is because during the pan feeding mouth 14 entering one of them or two metering tanks 9 of self gravity from pan feeding baffle 13, because pan feeding mouth 14 less than or equal to metering tank 9 notch, consequently, the metering tank 9 that lies in quantitative output mechanism 6 and is located directly over this moment and communicates through pan feeding mouth 14 and sampling tube 1 all can be filled completely by the material. The feeding port 14 is designed right above the quantitative output mechanism 6 to prevent the side metering grooves 9 from being completely filled, which causes inaccurate metering of the single metering groove 9.

The discharge port 10 can be located under the quantitative output mechanism 6, but the position is not strictly required, as long as the material in the metering tank 9 can fall out through the discharge port 10 by self gravity, because the discharge port 10 is less than or equal to the notch of the metering tank 9, under the condition of rotating the quantitative adjusting button 7 at a certain speed, the condition that the materials in the two metering tanks 9 fall out simultaneously can not appear, namely when slowly rotating the quantitative adjusting button 7, one of the metering tanks 9 enters the range of the discharge port 10 first, the material falls out by self gravity, the quantitative adjusting button 7 is temporarily stopped to be rotated until all the materials in the metering tank 9 fall out, and then the rotation is continued, and the operation is repeated in sequence until the next metering tank 9 enters the range of the discharge port 10.

The quantitative adjusting button 7 and the side wall of the sampling tube 1 can be rotated to mark scales corresponding to the metering groove 9 for indicating whether the metering groove 9 is just below the feed inlet 14 or just above the discharge outlet 10.

The feeding baffle 13 and the discharging baffle 8 are both cambered surface structures matched with the side surface of the quantitative output mechanism 6, the feeding baffle 13 and the discharging baffle 8 are tightly attached to the side surface of the quantitative output mechanism 6, the feeding baffle 13 surrounds the upper half part of the quantitative output mechanism 6, and the discharging baffle 8 surrounds the lower half part of the quantitative output mechanism 6.

The feeding baffle 13 can be provided with a slope to form a funnel shape, so that the materials can be conveniently poured into the metering tank 9.
