Abstract

The invention discloses a land surveying sampling device convenient for storage for agricultural use. The land surveying sampling device convenient for storage for agricultural use includes a supportplate and a motor; a support frame is fixedly welded on the upper end of the support plate, and the upper end of the support frame is fixedly sleeved on the outer side of a sleeve; the upper end of the sleeve is fixedly welded to the lower end of a base plate, and the upper end of the base plate is fixedly and symmetrically equipped with four universal wheels; a screw rod is inserted at the lowerend of the sleeve, and a nut is sleeved on the screw rod; and the nut is rotatably installed at the lower end opening of the sleeve through a bearing. According to the invention, a first sampling plate and a second sampling plate are arranged to be combined into a sampling cylinder, and the first sampling plate and the second sampling plate can be separated, therefore, the sample is easy to be taken out; in addition, a vent hole is arranged, so that the soil enters the inside of the first sampling plate and the second sampling plate, and the air pressure inside the first sampling plate and thesecond sampling plate can be exhausted through the vent hole, therefore, sampling difficulties due to excessive air pressure inside the cylinder are prevented.

Description

technical field

[0001] The invention relates to the technical field of agricultural land survey and sampling devices, in particular to an agricultural land survey and sampling device that is convenient for storage. Background technique

[0002] In agricultural scientific research, it is necessary to sample the soil of the farmland in order to analyze and detect the soil, so that the crops can grow better, and the sampling devices in the prior art are usually large in size, and it is inconvenient to carry and store In addition, the current sampling devices all use sampling cylinders for soil sampling, which has a simple structure and is troublesome when taking the samples out of the cylinder. In addition, after the opening of the cylinder enters the cohesive soil, the soil will form a piston in the cylinder, which will cause the inside of the sampling cylinder to The air pressure will increase with the increase of clay, which makes it difficult for the sampling cylinder to de...
