Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a silt sampler, including inner tube 1, outer tube 2, appearance post 3 and drill bit 4. Stretch into drill bit 4 downwards earlier, insert inner tube 1 and outer tube 2 in the silt layer completely, upwards pull outer tube 2, make inner tube 1 expose, seted up feed inlet 12 on the inner tube 1, the sample enters into inner tube 1 from feed inlet 12 and collects.

Referring to fig. 2, a partition plate 11 is disposed on a pipe wall of the inner pipe 1, the partition plate 11 has the same cross-sectional area as the inner pipe 1, and a plurality of partition plates 11 are disposed along a length direction of the inner pipe 1, in this embodiment, two partition plates 11 are disposed to divide the inner pipe 1 into three equal upper and lower regions. The inner tube 1 between two adjacent clapboards 11 is provided with a feed inlet 12 for sampling in three areas respectively. Like this, can once only get the silt of three different degree of depth, reduce the sample number of times, save time cost. The feed inlet 12 is formed in a square opening and is positioned below the partition plate 11 close to the upper end, and water entering the inner tube 1 overflows outwards along the feed inlet 12, so that samples are kept in the inner tube 1 as much as possible.

Referring to fig. 3, the outer tube 2 is slidably coupled to the outside of the inner tube 1, and a sliding assembly for moving the outer tube 2 up and down along the inner tube 1 is provided between the outer tube 2 and the inner tube 1. The arrangement of the sliding assembly can connect the inner pipe 1 and the outer pipe 2. The sliding component comprises a sliding groove 13 arranged on the side wall of the inner pipe 1 and a sliding block 14 fixedly connected to the outer pipe 2. The length direction setting of inner tube 1 is followed to spout 13, and spout 13 sets to square groove, and slider 14 sets up on the inner wall of outer tube 2, and is close to the position of outer tube 2 lower extreme, and slider 14 sets to the shape with spout 13 assorted to can slide along the direction of spout 13, drive reciprocating of outer tube 2, realize the switching of the feed inlet on the inner tube 1.

A placing groove 15 is formed on the outer portion of the inner tube 1, and the placing groove 15 is arranged at the upper end of the sliding groove 13, is perpendicular to the sliding groove 13, and is communicated with the sliding groove 13. The placement groove 15 is matched with the shape of the slider 14, and when the slider 14 rotates the uppermost end of the slide groove 13, the outer tube 2 is rotated to rotate the slider 14 into the placement groove 15. When the sample of inner tube 1, the cooperation setting of slider 14 and standing groove 15 can make outer tube 2 card on the outer wall of inner tube 1, can not drop from inner tube 1, influences the normal sample of inner tube 1.

The inner tube 1 need rotate the inner tube 1 and grind the sample at the in-process of sample, and the sample that the grinding got off enters into the region that the inner tube 1 corresponds along feed inlet 12 in, the convenient sampling. Therefore, the grinding blocks 16 are fixedly connected to the outer part of the inner tube 1, and the grinding blocks 16 are arranged in a strip structure and uniformly distributed on the side wall of the inner tube 1 arranged between the feeding holes 12 in a surrounding mode. When the grinding block 16 rotates, the sand is removed, so that the sample enters the inner tube 1 from the feed port 12 during the rotation of the inner tube 1.

Referring to fig. 4, fixedly connected with baffle 5 is gone up in the closing of the top of outer tube 2, and baffle 5 passes the thief column 3 and sliding connection is on thief column 3, and the setting of baffle 5 blocks the gap between inner tube 1 and outer tube 2, prevents during rivers flow into the gap between inner tube 1 and outer tube 2, and after the sample was accomplished, slide outer tube 2 to the outer lane of inner tube 1, carry out the shutoff to the feed inlet. The upper end fixed connection handle of thief column 3, the inner tube is conveniently rotated in setting up of handle.

Referring to fig. 1, the lower extreme of drill bit 4 sets up to the taper structure, and the cross-sectional area of drill bit 4 from bottom to top crescent, and drill bit 4 of taper structure makes things convenient for this embodiment to insert downwards, reduces the frictional force of the contact surface of drill bit and silt, makes things convenient for this device to enter into and takes a sample under the water layer more.

The implementation principle of the embodiment is as follows:

the lower end of the drill 4 is inserted below the water layer and the inner tube 1 and the outer tube 2 are positioned at the location where the sample is to be taken. The outer tube 2 is pulled upwards, and the slide block 14 arranged on the outer tube 2 is screwed into the placing groove 15, so that the feeding hole 12 on the inner tube 1 is exposed. Rotate the appearance pillar 3, make inner tube 1 rotatory, grinding block 16 on the outer wall of inner tube 1 cuts silt, makes things convenient for the sample to enter into in the inner tube 1 from feed inlet 12. Baffle 11 that sets up in inner tube 1 can keep off the position to the sample that the collection was accomplished, prevents that the sample of the different degree of depth from crossing, influences the accuracy that the sample detected. After the sampling is finished, the device is taken out from the sediment. This embodiment can once only gather the silt of three different degree of depth, saves the collection number of times, simplifies the sampling step, has stronger practicality.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
