Embodiment 1

[0029] This embodiment provides a verification device for the decomposition efficiency of straw by bacteria in the soil carbon cycle experiment. By setting the soil dumping mechanism 3, the main supporting plate 301 plays a role of supporting the whole bag of soil, and the cylinder 302 drives the main supporting The plate 301 rises and tilts towards the cylinder body 1; further, by adding an auxiliary supporting plate 304, it can play an auxiliary supporting role for the bottom end of the whole bag of soil at the initial stage of the main supporting plate 301 rising; further, by adding The anti-leakage plate 303 can well connect the main support plate 301 and the cylinder body 1 to prevent the soil from slipping from the packaging bag to the inside of the cylinder body 1 from material leakage. details as follows.

Embodiment 2

[0033] Embodiment 2 is an improvement made on the basis of Embodiment 1. The main improvement is reflected in the addition of a packaging bag fixing mechanism 4 and a fixing claw position adjustment mechanism 5, wherein the sliding plate 402 freely slides up and down perpendicular to the direction of the main supporting plate 301, and is fixed The claw 401 approaches or moves away from the main supporting plate 301 under the drive of the sliding plate 402. When the sliding plate 402 slides to the lowest position, the fixing claw 401 tightly engages the packaging bag on the main supporting plate 301 to prevent the packaging bag from Slide down to the inside of cylinder body 1 together with the soil; the handle 501 drives the gear 504 to rotate through the connecting sleeve, and the gear 504 drives the sliding plate 402 to slide up and down through the tooth plate 505 to adjust the distance between the fixed claw 401 and the main supporting plate 301, which is convenient to adjust...

Embodiment 3

[0039] Embodiment 3 is an improvement made on the basis of Embodiment 2. The main improvement is reflected in the addition of support legs 18 and rollers 19, which can play an auxiliary supporting role for the main support plate. The supporting leg 18 is hinged with the movable rod 2 20, and the supporting leg 18 and the roller 19 can be accommodated towards the direction of the cylinder body 1 when the main supporting plate rises and tilts, so as to reduce the lifting force of the cylinder 302. details as follows.

Abstract

The invention provides a device for verifying the straw decomposition efficiency of bacteria in a soil carbon cycle experiment, and belongs to the technical field of soil detection and treatment. Theverifying device comprises a cylinder body, an annular mounting seat, a soil dumping mechanism, a packaging bag fixing mechanism and a fixing claw position adjusting mechanism. By arranging the soil dumping mechanism, a main bearing plate plays a role in bearing a whole bag of soil, and an air cylinder drives the main bearing plate to ascend, so that the soil automatically slides into the cylinderbody from a packaging bag; by arranging the packaging bag fixing mechanism and the fixing claw position adjusting mechanism, the packaging bag can be tightly clamped on the main bearing plate, and the packaging bag is prevented from sliding into the cylinder body along with soil; and by additionally arranging supporting legs and rolling wheels, the auxiliary supporting effect on the main bearingplate can be achieved, the supporting legs are additionally arranged to be hinged to a third hinge seat and a second movable rod, the supporting legs and the rolling wheels can be stored in the direction of the cylinder body in the ascending and inclining process of the main bearing plate, and the lifting force of the air cylinder is reduced.

Description

technical field [0001] The invention belongs to the technical field of soil detection and treatment, and specifically relates to a verification device for the decomposition efficiency of straw by bacteria in soil carbon cycle experiments. Background technique [0002] my country's main food crops mainly refer to wheat and rice. After rice and wheat are harvested and threshed, the stems and leaves left behind are collectively called straw. Straw is rich in nitrogen, phosphorus and potassium. The traditional method is to leave the straw ash in the field by burning to provide nutrients for the next crop. However, burning straw produces a large amount of particulate matter that induces smog in autumn and winter, which is not conducive to environmental protection. The prior art proposes a bacterial degradation retting method, which not only does not pollute the environment, but also can retain nitrogen, phosphorus, potassium and other elements to the greatest extent, and thus h...
