Description

soil sampler

technical field

The utility model belongs to the technical field of sampling equipment, relates to a sampler, in particular to a soil sampler.

Background technique

In the work of soil census, soil monitoring and soil testing and formula fertilization, a soil sampler that meets the requirements of full layer, equal volume and convenience must be equipped. Existing soil samplers are mostly manual operations, including drill handles and cylindrical hollow drill bodies. Although the structure is simple and the cost is low, it is time-consuming and labor-intensive, and it is prone to clogging when taking soil. At the same time, since most of the sampling cylinders are straight, it is not easy to pull out the sampling cylinder after being pressed into the soil layer, and the obtained soil samples are not easy. It is easy to take out from the sampling cylinder, which makes soil sampling difficult and cannot meet the needs of soil sampling.

Utility model content

The purpose of the utility model is to provide a soil sampler with simple structure, fast soil taking speed and convenient operation.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: soil sampler, including oil pick, soil extractor and crowbar, support, wrench and base matched with the soil extractor, the support matches the crowbar, and the soil extractor Including the alloy rod head connected with the oil pick, the dowel rod and the sampling cylinder are connected in sequence under the alloy rod head; the dozer rod is provided with a bulldozing disc, and the bottom end of the bulldozing disc is set in the sampling cylinder; the outer wall of the sampling cylinder bottom is There is a slope on the top, and the diameter of the outer wall of the middle part of the sampling cylinder is smaller than the diameter of the outer wall of the end; a number of bulldozer pin holes are vertically provided on the bulldozer; The rod is also provided with a double-sided groove corresponding to the bulldozing pin hole.

Further, the dowel bar is provided with a pin hole, and a crowbar positioning pin matched with the crowbar is pierced in the pin hole.

Further, a wrench positioning block is fixed on the dowel bar.

Furthermore, a hole matched with the sampling cylinder is provided on the top surface of the base.

Compared with the prior art, the beneficial effects of the utility model are as follows: the soil sampler includes an oil pick, a soil extractor and a crowbar, a support, a wrench and a base matched with the soil extractor, and the support matches the crowbar, Each component cooperates to complete soil sampling, with simple structure and convenient operation; the soil fetcher includes an alloy rod head connected with an oil pick, and a dowel rod and a sampling cylinder are connected in turn under the alloy rod head, and the length of the dowel rod can be set according to sampling requirements , at the same time, the sampling depth can be increased by increasing the number of dowel bars. The dowel rod directly transmits the power to the sampling cylinder, with small power loss and high sampling efficiency; a bulldozer is installed in the dowel rod, and the bottom end of the bulldozer is set in the sampling cylinder, and the bulldozer can push the sample out of the sampling cylinder. The structure is simple and the operation is convenient; there is a slope on the outer wall of the bottom of the sampling cylinder, and the slope is processed at the nozzle of the outer wall of the sampling cylinder. Under the high pressure hammering of the oil pick, the sampling cylinder can smoothly enter the soil, and the sampling cylinder The soil is squeezed tightly and is not easy to fall off, which improves the accuracy of sampling; the diameter of the outer wall of the middle part of the sampling cylinder is smaller than the diameter of the outer wall of the end, which reduces the contact area between the middle part of the sampling cylinder and the soil. During the process of pressing the sampling cylinder into the soil or pulling it out, The contact between the sampling cylinder and the soil is less, the friction force is also reduced, the operation is more convenient and the energy consumption is reduced; a number of bulldozer pin holes are vertically arranged on the bulldozer plate, and the pins are inserted into the bulldozer pin holes, and the wrench moves the pins and then Drive the bulldozer to move, with simple structure and low cost; the dozer is fixed with a spring buckle that matches the bulldozer, and the spring buckle is used to fix the bulldozer to avoid the problem that it is easy to fall off when it is fixed with a pin , easy to use and reduce workload; there is also a double-sided groove corresponding to the bulldozer pin hole on the dowel bar, push the pin into the pin hole and insert the pin, and the wrench can move the pin to move in the double-sided groove to drive the bulldozer The plate moves, the structure is simple and easy to use; there is a pin hole on the dowel bar, and the crowbar positioning pin matched with the crowbar is pierced in the pin hole, which is reasonable in design and easy to use; the dowel bar is fixed with a wrench positioning pin. One end of the wrench leans against the wrench positioning block, and the middle part of the wrench leans against the pin inserted in the bulldozing pin hole, using the principle of leverage to push the bulldozing disk, which reduces working steps and is easy to use; there is a sampling cylinder on the top surface of the base With matching holes, the sampling cylinder is inserted into the sampling cylinder, and the sample in the sampling cylinder is pushed into the base by the bulldozing disc to avoid sample contamination.
