specific Embodiment approach 1

[0025] Specific embodiment one: present embodiment is a kind of adjustable root-soil complex sampler that is used for excavation method in black soil area, and it is made up of adjustable telescopic frame and horizontal propulsion type cutter;

[0026] The adjustable telescopic frame includes a stressed beam 1, two support rods 2, a telescopic rear wall 3, two side walls 4, a side wall scale line 5, a rear wall overlapping line 6, a cutting edge 7 and a cutting groove 8. The telescopic rear wall 3 is composed of two telescopic walls, the two telescopic walls are butted together along the overlapping line 6 of the rear wall according to the docking form, and the other side of the two telescopic walls parallel to the overlapping line 6 of the rear wall The sides are vertically fixedly connected to one side wall 4 respectively, and a support rod 2 is fixedly connected to the top sides of the two side walls 4 respectively, and the two support rods 2 are connected to the stressed be...

specific Embodiment approach 2

[0029] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the telescopic rear wall 3 and the bottom of the two side walls 4 are provided with a cutting edge 7 whose top ends are on the same plane. Others are the same as the first embodiment.

[0030] When telescopic rear wall 3 and two side walls 4 bottoms are provided with cutter blade 7 tops and are in the same plane, the plane formed by cutter groove 8 is set on two side walls 4 and telescopic rear wall 3 and two side walls 4 The bottom is provided with the planes formed by the cutting edge 7 to be parallel. Ensure that the lower section of the root-soil complex is parallel in the horizontal direction.

[0031] In this embodiment, the top ends of the cutting blades 7 are on the same plane for the purpose of balancing the force during the process of the adjustable telescopic frame entering the soil, so as to ensure that the adjustable telescopic frame enters the soil at a uniform speed.

specific Embodiment approach 3

[0032] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the plane composed of the stressed beam 1 and the two support rods 2 is perpendicular to the two side walls 4 . Others are the same as those in Embodiment 1 or 2.

[0033] The design purpose of this embodiment is to ensure that the adjustable telescopic frame is balanced in force during the entry and extraction process, to ensure that the sampling target is taken out in the form of a cube or a cuboid as a whole, and to prevent uneven force from causing damage to the sampled soil.

Abstract

The invention discloses an adjustable root-soil composite sampler for excavation in black soil regions and a usage method thereof, relates to a root-soil composite sampler and a usage method thereof, and aims to solve the problem that a soil body separation phenomenon occurs in a process of taking the cuboid or cuboid soil block in black soil regions or the lower tangent plane of an obtained cuboid or cuboid soil block cannot be parallel with the upper tangent plane. The adjustable root-soil composite sampler for excavation in black soil regions consists of an adjustable telescopic framework and a horizontal propelling cutter, wherein the adjustable telescopic framework comprises a stressed transverse beam, a support rod, a telescopic back wall, a side wall, a side wall graduation mark, a back wall overlapping line, a cutter edge and a cutter groove; the horizontal propelling cutter consists of a horizontal propelling cutter body, a horizontal propelling cutter edge and a horizontal propelling cutter stressed handle. The usage method comprises the following steps: I, preparing a sampling region; II, gaining a root-soil composite; III, harvesting a sample. The adjustable root-soil composite sampler is mainly applied to soil sampling in southeast black soil regions.

Description

technical field [0001] The invention relates to a method for using a root-soil composite sampler. Background technique [0002] The black soil area in Northeast my country, the black soil area in the Great Plains of Ukraine, and the black soil area in the Mississippi River Basin in the United States are known as the three famous black soil areas in the world. The northeast black soil area is mainly distributed in the eastern part of the Songnen Plain, including 90 cities and counties in Heilongjiang, Jilin, Liaoning Province and Inner Mongolia Autonomous Region. Black soil is clay soil with strong expansion and contraction and disturbance characteristics. It is a kind of soil with good properties and suitable for plant growth. The Northeast black soil area is the most important commodity grain base in my country and occupies an important position in the overall structure of the national economy. Therefore, research on crops and economic crops growing on black soil has also...
