Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a soil sampler. Referring to fig. 1, the sampler comprises a handle 1 and a sampling head 2 installed at the front end of the handle 1, wherein the sampling head 2 is conical; when sampling, the sampling head 2 firstly enters the soil layer, and the conical sampling head 2 enables the sampler to enter the soil layer more quickly. And applying force to the handle 1 so as to enable the sampling head 2 to penetrate into the soil layer to complete sampling.

Referring to fig. 1, two handles 11 are fixedly connected to the end of the handle 1, the two handles 11 are symmetrically arranged, and the handles 11 and the handle 1 are perpendicular to each other. The handle 11 is also sleeved with two rubber sleeves 12, and the rubber sleeves 12 are fixedly connected with the handle 11. Force is applied to the handle 1 through the handle 11 more easily, and the handle 1 is driven to enter the soil layer; the rubber sleeve 12 reduces the discomfort when the hand contacts the handle 11.

Referring to fig. 1 and 2, a graduated scale 13 is embedded on the circumferential surface of the handle 1, and the length direction of the graduated scale 13 is the same as that of the handle 1; the deep depth of the handle 1 is observed more clearly through the graduated scale 13, when a deep soil layer needing sampling is reached, sampling is carried out in time, the deep depth of the handle does not need to be measured and calculated, and the work efficiency is improved.

Referring to fig. 1 and 2, tooth 21 of round has all been seted up on the tip that sampling head 2 and handle 1 are close to each other, tooth intermeshing on sampling head 2 and the handle 1 to make sampling head 2 and handle 1 complex inseparabler, can also make things convenient for sampling head 2 to carry out the work of taking a sample. The inside cavity of sampling head 2 sets up, and the sample of conveniently getting stores.

Referring to fig. 1 and 2, 1 interpolation of handle is equipped with threaded rod 3, and threaded rod 3 link up the both ends of handle 1, and threaded rod 3 and 1 screw-thread fit of handle, and threaded rod 3 and the coaxial setting of handle 1, and threaded rod 3 is close to the one end of sample head 2 and articulates there is connecting rod 31, and connecting rod 31 keeps away from the one end of threaded rod 3 and passes through the bearing rotation with sample head 2 and connect to make threaded rod 3, connecting rod 31's rotation can not receive sample head 2 to influence. When needs sample, rotate threaded rod 3, because threaded rod 3 and 1 screw-thread fit of handle, so 3 drive sampling heads of threaded rod 2 remove to the direction of keeping away from handle 1, sampling heads 2 is at the in-process that removes, go into the soil layer deeply once more, cause the damage to the soil layer, and then realize the work of sample, when moving to the direction of being close to handle 1 through 3 drive sampling heads of threaded rod 2, tooth 21 on the sampling heads 2 can cause further destruction to the soil layer, sample once more, thereby ensure the integrality of sample.

Referring to fig. 2 and 3, the junction of threaded rod 3 and connecting rod 31 is equipped with gag lever post 4, all seted up recess 32 on the lateral wall of threaded rod 3 and connecting rod 31, recess 32 on threaded rod 3 and the connecting rod 31 aligns each other, gag lever post 4 is in recess 32, gag lever post 4 makes threaded rod 3 and connecting rod 31 be rigid connection, so when the during operation that takes a sample is carried out to 3 drive sampling heads 2 of threaded rod, avoid sampling head 2 to produce the skew, make sampling head 2 normally carry out the work of taking a sample.

Referring to fig. 3 and 4, both ends of the limit rod 4 are fixedly connected with an insertion rod 41, the insertion rod 41 is perpendicular to the limit rod 4, and the bottom surfaces of the connecting rod 31 and the groove 32 on the threaded rod 3 are both provided with insertion holes 33 for inserting the insertion rod 41; so that the limit rod 4 is more stably mounted on the side walls of the threaded rod 3 and the connecting rod 31.

Referring to fig. 3 and 4, a chamfer 42 is formed at one end of the insertion rod 41, which is far away from the limiting rod 4, and the chamfer 42 enables the insertion rod 41 to more rapidly enter the insertion hole 33, so that the speed of installing the limiting rod 4 is increased, and the working efficiency is improved.
