Handheld pressure rotating soil sampler

Abstract

The invention relates to a handheld pressure rotating soil sampler, which belongs to the technical field of agricultural machinery. The handheld pressure rotating soil sampler comprises a push rod, a holding drum, an inner sleeve, an upper compression spring, a clutch movable part, a lower compression spring and a rotating drum; the push rod comprises a holding pipe, a connecting pipe and a push-down part, the holding drum comprises an upper stop part, a connecting drum, an outer drum and a clutch fixed part, the inner sleeve comprises an upper clamping part, an inner bushing and a lower clamping part, the upper compression spring sleeves the inner bushing, the clutch movable part sleeves the connecting pipe, the inner diameter of the clutch movable part is larger than the outer diameter of the connecting pipe, the upper end of the clutch movable part is provided with a single-direction clutch gear which is matched with a single-direction clutch gear on the lower end of the clutch fixed part to rotate, the lower compression spring sleeves the connecting pipe and is installed between the clutch movable part and a lower stop part in the rotating drum, and the rotating drum comprises a middle clamping part, a soil sampling pipe and the lower stop part. The handheld pressure rotating soil sampler is convenient and rapid to use, simple in structure, precise to operate and capable of preventing a soil sample from directly contacting hands of people when the soil is sampled.

Description

technical field [0001] The invention relates to a hand-held pressure rotary soil fetcher, which belongs to the technical field of agricultural machinery. Background technique [0002] my country is a large agricultural country, and agriculture is the foundation of the national economy. In our country, planting is the main body of agriculture. Planting is greatly affected by natural conditions. It requires land suitable for farming. Generally, it requires flat terrain, deep and fertile soil, rich water sources, and convenient irrigation. Among them, soil Played a vital role, so the soil in different regions needs to be sampled and tested. [0003] At present, soil fetchers used in agricultural soil sampling in my country can be divided into automatic and artificial. In the actual soil sampling process, after the automatic type and the manual type take the soil sample, manual operation is required to take the soil sample out of the soil taking pipe of the soil taking device,...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the present invention provides a hand-held pressure rotary soil fetching device, which is used to solve the problem that the sampling person will consume a lot of physical strength in the process of using the traditional soil fetching device to obtain soil, and it is impossible for the sampling person to observe and take the soil by himself. The depth of the earthenware will cause sampling errors, requiring extra manpower to help complete the soil extraction operation, and during the soil extraction process, the soil sample will stick in the soil extraction pipe of the earthen equipment, it is not easy to take out, and the operation is troublesome, etc.
