Efficient soil sampler

Abstract

The invention discloses an efficient soil sampler which comprises a bulldozing sliding block, a cutting ring, a hollow connecting rod, a pedal assembly I, a pedal assembly II, a push rod, a bulldozinghandle and a soil pressing handle; the bulldozing sliding block is connected with the push rod through threads, the push rod is welded to the bulldozing handle through limiting blocks and pedal innerholes, the limiting blocks are welded to the hollow connecting rod, and pedals are mounted on the limiting shafts via limiting holes; the cutting ring is connected to the hollow connecting rod through threads, and the hollow connecting rod is welded to the soil pressing handle. According to the efficient soil sampler, soil in different depths can be taken out by means of the pedals in different positions, the sampling efficiency for soil relatively deep in the field can be improved substantially, an extra pedal is not needed, the pedals can be rotated to the vertical direction after soil sampling and the sampler is characterized by being portable and efficient.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a soil fetcher suitable for carrying out high-efficiency deep soil fetching in farmland scientific experiments. Background technique [0002] Deep soil extraction in the field is often accompanied by a huge amount of soil samples. Existing soil fetchers used in deep soil in the field mainly use the handle to press the soil ring knife to enter different depths below the surface, and then take out soil samples at different depths. Due to the high handle of the earth taker in the ring knife entry stage, it is difficult to apply vertical pressure on the handle, which has the problems of difficulty in entry into the soil, low efficiency of soil extraction, and heavy workload; although some earth extractors are equipped with foot pedals plate, but it can only work at one position where the ring knife and the hollow connecting rod are combined, and it is also difficult to significa...

[0002] Deep soil extraction in the field is often accompanied by a huge amount of soil samples. Existing soil fetchers used in deep soil in the field mainly use the handle to press the soil ring knife to enter different depths below the surface, and then take out soil samples at different depths. Due to the high handle of the earth taker in the ring knife entry stage, it is difficult to apply vertical pressure on the handle, which has the problems of difficulty in entry into the soil, low efficiency of soil extraction, and heavy workload; although some earth extractors are equipped with foot pedals plate, but it can only work at one position where the ring knife and the hollow connecting rod are combined, and it is also difficult to significantly improve the work efficiency of the earth taker, and the added foot pedal makes the structure of the earth taker more complicated, which is not easy to install. transportation and storage; in view of this, there is an urgent need to design a portable high-efficiency soil fetcher suitable for deep soil fetching in the field
