Abstract

The utility model relates to a granary sampler, which comprises a main machine, a connecting pipe fitting, a sampling tube and extension tubes, wherein, the extension tubes are in screwed connection with the tail part of the sampling tube; all the extension tubes are in head-to-tail connection; the connecting pipe fitting is communicated with the extension tubes and the main machine; an annular external depressed part is bulldozed from the outer side at one end of each extension tube, and an internal depressed part corresponding to the external depressed part is also bulldozed from the lateral wall at the other end of each extension tube; threads are formed at the internal depressed part and the external depressed part; an annular internal depressed part and an annular external depressed part are also arranged at the tail end of the sampling tube; and threads are also formed at the depressed parts. The utility model has the advantages of small resistance during the sampling process and can extend into the deeper position for sampling.

Description

The silo sampler

Technical field

The utility model relates to a kind of sampler of grain, specifically is a kind of silo sampler.

Background technology

Present silo sampler mainly is made up of main frame, connecting tube, stopple coupon and extension pipe, wherein the extension pipe number can be adjusted according to the degree of depth of silo, be connected the mode that spins that all adopts spiral between present extension pipe and stopple coupon or the extension pipe, the external diameter of the junction between extension pipe and stopple coupon or extension pipe is bigger slightly than the external diameter of pipe shaft, when the silo degree of depth is dark, extension pipe that this structure connects and stopple coupon just can't extend into darker position and take a sample because resistance is bigger.

The utility model content

The purpose of this utility model is the syndeton of a kind of silo sampling extension pipe and stopple coupon is suitably improved, and makes that the external diameter that connects the junction, back is identical with the external diameter of body, and resistance is little when taking a sample, and can extend into more deep-seated and put and take a sample.

The utility model is achieved in that

A kind of silo sampler, comprise main frame, connecting tube, stopple coupon and extension pipe, extension pipe is screwed in the afterbody of stopple coupon, join end to end before each extension pipe, connecting tube is communicated with extension pipe and main frame, it is characterized in that: dig out the outer depressed part of an annular in the wherein end of the described extension pipe outside, the madial wall of the other end of extension pipe also dig out one with outside the corresponding sunken inside of depressed part portion, the place is equipped with screw thread at inside and outside depressed part; Described stopple coupon not the end also offer the annular sunken inside portion or outside depressed part, also be provided with screw thread at the depressed part place.

The utility model digs out depressed part in the end of extension pipe and stopple coupon, and screw thread is set at the depressed part place, adopt this structure after spinning between stopple coupon and extension pipe or the extension pipe, the external diameter of junction external diameter and extension pipe or stopple coupon is identical between extension pipe and stopple coupon or the extension pipe, the external diameter of pipeline keeps smooth behind extension pipe in the stopple coupon connection like this, resistance when silo stretches into sampling significantly reduces, and also can finely stretch into sampling even therefore the silo degree of depth is very dark.

The structural representation of Fig. 2, the utility model extension pipe;

Fig. 3, this reality have the structural representation of novel stopple coupon.

Embodiment

As a kind of silo sampler of Fig. 1, comprise main frame 1, connecting tube 2, stopple coupon 3 and extension pipe 4, extension pipe 4 is screwed in the afterbody of stopple coupon 3, join end to end before each extension pipe 4, connecting tube 2 is communicated with extension pipe 4 and main frame 1, as shown in Figure 2, digs out the sunken inside portion 41 of an annular in the outside of the lower end of described extension pipe 4, the madial wall of the upper end of extension pipe 4 also dig out one with outside depressed part corresponding outside

depressed part

42,41,42 places are equipped with screw thread at inside and outside depressed part; As shown in Figure 3, the not end of described stopple coupon 3 also offers the outer depressed part 42 of annular, and depressed part 42 places also are provided with screw thread outside this.

The utility model is done suitable improvement to the structure of extension pipe and stopple coupon junction, between the extension pipe or extension pipe be connected with stopple coupon the back junction external diameter the same with the external diameter at extension pipe or other position of stopple coupon, stopple coupon and the position that does not have projection after extension pipe is connected like this, the resistance that stopple coupon and extension pipe stretch into when silo is taken a sample significantly reduces, and can finish the sampling work of the dark silo of the degree of depth.

Claims

1, a kind of silo sampler, comprise main frame, connecting tube, stopple coupon and extension pipe, extension pipe is screwed in the afterbody of stopple coupon, join end to end before each extension pipe, connecting tube is communicated with extension pipe and main frame, it is characterized in that: dig out the outer depressed part of an annular in the wherein end of the described extension pipe outside, the madial wall of the other end of extension pipe also dig out one with outside the corresponding sunken inside of depressed part portion, the place is equipped with screw thread at inside and outside depressed part; Described stopple coupon not the end also offer the annular sunken inside portion or outside depressed part, also be provided with screw thread at the depressed part place.
