Embodiment Construction

[0032] Such as figure 1 As shown, the present invention includes a soil drill 1, the top of the soil drill 1 is threadedly connected with the connector 3 through a spring washer 2, the electric pick 4 is arranged above the connector 3, and the electric pick 4 obtains the power supply of the generator 5 through the electric wire 6, The power supply is 220V or other AC power supply. Driven by the generator 5, the electric pick 4 continuously strikes the connector 3 at high frequency and high speed. Under vibration and impact, it can enter the predetermined depth within tens of seconds without disturbing the soil sample, and the operation is simple, saving time and effort.

[0033] Among them, the electric pick 4 and the connecting head 3 are detachably connected, that is, the sleeve in the electric pick 4 is directly inserted into the connecting head 3, and the sleeve and the connecting head 3 are in clearance fit, relying on the weight of the electric pick 4 to press on the co...

Abstract

The invention discloses a high-speed and high-frequency percussion electric undisturbed soil sampler with high-speed and high-frequency percussion. The electric undistributed soil sampler comprises a soil sampling drill; the top part of the soil sampling drill is in threaded collection with a connector; an electric pick is arranged over the connector and powered by a generator. The invention has the advantages that: 1, compared with the current widely-used manual agricultural soil sampler, the electric undistributed soil sampler with the electric pick and the generator saves a mass of labor, is high in soil sampling efficiency which is ten times that of the manual soil sampler, and completely overcomes the difficulty in agricultural soil analysis and sampling; 2, the soil sampler is simple, can be conveyed and operated by only two people, and is characterized by portability and convenience for operation. Compared with an automobile soil sampler for geological exploration, the eclectic undisturbed soil sampler has the advantages of portability and simplicity in operation.

Description

technical field [0001] The invention relates to a high-speed and high-frequency impact undisturbed soil electric soil fetcher for analyzing and testing field soil and obtaining undisturbed soil samples in agricultural soil scientific research. Background technique [0002] There are two types of soil fetchers: rotary type and direct pressure type. When the rotary soil fetcher is fetching soil, due to the viscosity of the soil, the head is very prone to blockage, so the soil fetching depth is limited each time, and the work efficiency is low. The power source of the rotary earth taker is generally a motor or a gasoline engine. The connection between the power source and the drill pipe is usually threaded, buckled, etc., and it is extremely inconvenient to run in and pull out the drill every time. [0003] The depth of the direct pressure soil fetcher is not limited at one time, and the soil fetcher can obtain several soil samples (generally 20cm for one soil sample in agricu...
