Description

Direct press type gasoline engine soil sample barrel

Technical field

The present invention relates to a kind ofly relate in the research of pedotheque at environment, agricultural etc. the gasoline engine direct press type that the obtains pedotheque machine that fetches earth.

Background technology

Soil sample barrel is divided into two types of rotary and direct press types.The rotation soil sample barrel occurs head easily and stops up when fetching earth, so the degree of depth that fetches earth is limited at every turn, work efficiency is low.The mode that conventional direct press type soil sample barrel general using people hammer is pounded is finished, and big to the injury of soil sample barrel, soil extracting efficiency is low.

Summary of the invention

The purpose of this invention is to provide the direct press type gasoline engine soil sample barrel that a kind of suitable root system fetches earth or the soil weight fetches earth.

For achieving the above object, the present invention is by the following technical solutions:

A kind of direct press type gasoline engine soil sample barrel, it comprises the cylinder that is driven by gasoline engine, wheel box, be inserted with the bar part that fetches earth in the cylinder, the described bar that fetches earth partly comprises impact bar, the impact bar that is connected with cylinder and the pipe that fetches earth is connected, the end setting of the pipe that the fetches earth head that fetches earth; The diameter of the described pipe that fetches earth is 90-120mm, and symmetry has at least three grooves that fetch earth on the pipe that fetches earth.

Have vent port at the described pipe that fetches earth.

At impact bar and fetch earth transmission rod is set between the pipe.

Transmission rod and fetch earth and be symmetrical arranged 3-4 reinforcements between the pipe.

The bowl of bulldozing is set in the described pipe that fetches earth, and cutting ring is equipped with in the bottom of the bowl of bulldozing, and in the bottom of cutting ring shoe is housed; At described transmission rod double groove is set, in the both sides of double groove at least two whippletrees is set.

Fix two pins at shoe; Have groove at the pipe that fetches earth, pin enters into groove, thereby makes being connected of shoe and the pipe that fetches earth.

The diameter of the described pipe that fetches earth is 100mm.

Adopting the present invention of technique scheme, is the direct press type soil sample barrel of power with the gasoline engine, and under the high frequency hammer action, the drill bit speed of burying is rapid, and embedded depth can reach more than several meters.Characteristics such as it is fast that this soil sample barrel has speed, simple to operate, time saving and energy saving, and quality is light, and is easy to carry.Specifically:

1, gasoline engine direct press type soil sample barrel is tens of times of manual soil extracting efficiency, has thoroughly solved in the research work soil difficult problem that fetches earth.

2, the whole equipment of this soil sample barrel is simple, and whole weight has only about 10 kilograms, is easy to carry, and is fit to very much open-air mobile soil sampling.

3, this soil sample barrel adopts high frequency hammering direct press type to fetch earth, and can keep the original state of soil.Direct press type fetches earth and also can not cause the obstruction of soil in the pipe that fetches earth, and soil extracting efficiency improves several times than rotary soil sample barrel efficient.

Embodiment

As shown in Figure 1, a kind of direct press type gasoline engine soil sample barrel, it comprises the cylinder 4 that is driven by gasoline engine 1, wheel box 3, and wherein, gasoline engine 1 and wheel box 3 are connected by flange, and the bar part 19 that fetches earth is inserted in the cylinder 4.Drift in the cylinder is done downward ballistic motion, and the bar part 19 that fetches earth is pounded (being that direct press type fetches earth) in the soil.The drift frequency of impact is about 3000 times/minute.

Wherein, power section comprises gasoline engine 1, handle 2, wheel box 3, cylinder 4 compositions such as grade.The power of gasoline engine is between 0.8-2.2 kilowatt, and maximum speed is below 9000 rev/mins.Wheel box 3 is by clutch coupling, gear, bent axle, connecting rod, compositions such as slide block; Cylinder 4 is by cylinder body, sliding block, and drift is formed.

As shown in Figure 2, the common bar part 19 that fetches earth comprises the impact bar 6 that is connected with cylinder 4, and torsion bar through hole 7 is set on the impact bar 6, and torsion bar through hole 7 is to cut native torsion bar in order to insert, and plays the effect of cutting soil and carrying soil.Impact bar 6 is welded to connect with the pipe 5 that fetches earth, and the end setting of the pipe 5 that fetches earth fetches earth 8.Fetching earth 8 has cutting edge, probably about 10 degree.

As shown in Figure 3, the fetch earth top of bar of root system is identical with the common bar that fetches earth, and gathering root system require the to fetch earth diameter of pipe is 90-120mm, at last about 100mm.Take out soil and root system for convenience, symmetry has at least three grooves 9 that fetch earth on the pipe 5 that fetches earth, and the groove 9 that fetches earth is to play the convenient effect that soil is taken out from pipe.For the pipe that fetches earth is buried smoothly, have vent port 11.In order to increase transmission rod 11 and the strength of joint of the pipe 15 that fetches earth, be symmetrically welded 3-4 reinforcement.In addition, transmission rod 10 is set at impact bar 6 and the pipe that fetches earth between 5.Transmission rod 10 and the pipe that fetches earth are symmetrical arranged 3-4 reinforcements 12 between 5.
