Problems solved by technology

The head of the rotary soil fetcher is prone to blockage when fetching soil, so the soil fetching depth is limited each time, and the work efficiency is low
Conventional direct-pressure soil extractors are generally completed by manual hammering, which causes great damage to the soil extractor and low soil extraction efficiency

Embodiment Construction

[0025] Such as figure 1 As shown, a direct-pressure gasoline engine earth taker includes a cylinder 4 driven by a gasoline engine 1 and a gearbox 3, wherein the gasoline engine 1 and the gearbox 3 are connected by a flange, and the soil fetching rod part 19 is inserted into the cylinder 4. The punch in the cylinder does a downward impact movement, and the soil-taking rod part 19 is smashed into the soil (that is, direct pressure type soil-taking). The impact frequency of the punch is about 3000 times / min.

[0026] Wherein, the power part includes gasoline engine 1, handle 2, gearbox 3, cylinder 4 and other components. The power of the gasoline engine is between 0.8-2.2 kilowatts, and the maximum speed is below 9000 rpm. The gearbox 3 is composed of clutches, gears, crankshafts, connecting rods, sliders, etc.; the cylinder 4 is composed of cylinder blocks, lower sliders, and punches.

[0027] Such as figure 2 As shown, the common earth-taking rod part 19 includes an impact...

Abstract

A direct-pressure gasoline engine earth taker, which includes a cylinder driven by a gasoline engine and a gearbox, and a soil removal rod part is inserted in the cylinder, and the soil removal rod part includes an impact rod connected to the cylinder, an impact rod and a soil removal pipe connection, the end of the soil-taking pipe is provided with a soil-taking head; the diameter of the soil-taking pipe is 90-120mm, and at least three soil-taking grooves are symmetrically opened on the soil-taking pipe. Adopting the present invention of the above-mentioned technical scheme, the direct-pressure soil fetcher powered by a gasoline engine, under the action of high-frequency hammering, the drill bit penetrates into the soil quickly, and the depth of penetration into the soil can reach more than several meters. The soil fetcher has the characteristics of fast speed, simple operation, time-saving and labor-saving, light weight, and easy to carry.

Description

technical field [0001] The invention relates to a gasoline engine direct-pressure soil borrowing machine for obtaining soil samples in the research involving soil samples such as environment and agriculture. Background technique [0002] There are two types of soil fetchers: rotary type and direct pressure type. When the rotary soil fetcher is fetching soil, the head is prone to blockage, so the soil fetching depth is limited each time, and the work efficiency is low. Conventional direct-pressure soil extractors are generally completed by manual hammering, which causes great damage to the soil extractor and low soil extraction efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a direct pressure gasoline engine soil fetcher which is suitable for soil fetching by root system or soil bulk density. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A direct-pressure ga...
