Problems solved by technology

[0002] Most of the soil samplers are semi-circular shovel-shaped samplers, which must be rotated continuously when used, and the soil structure of the soil samples taken out is damaged, and the sampling depth is not accurate, so that the obtained soil samples cannot truly reflect the soil itself traits
Although the existing T-shaped sampler is more convenient to use, its sampling head has certain insecurity, and its design structure also has certain defects, especially it is difficult to collect soil after sampling

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] like figure 1 , figure 2 As shown, the present invention includes a first handle 1, a sampling rod 2, a ring cutter bit 4, a soil removal rod 5, a drill rubber sheath 6, a soil extraction pliers 7 and a soil removal piston 8, wherein the sampling rod 2 is an internal hollow structure, One end is welded to the middle of the first handle 1 , the other end is welded with a ring cutter drill 4 , and a sampling groove 3 is opened on the sampling rod 2 along the length direction.

[0020] The first handle 1 and the sampling rod 2 in this embodiment are made of white steel pipes, with an inner diameter of 3.0 cm, an outer diameter of 3.2 cm, and a wall thickness of the white steel pipe of 0.1 cm. One end of the sampling rod 2 is vertically welded in the middle of the first handle 1, that is, the first handle 1 and the sampling rod 2 are in a "T" shape; the...

Abstract

The invention relates to an agricultural soil sampling apparatus, and concretely relates to a handheld soil in situ sampler. The sampler comprises a first handle, a sampling rod, a ring cutter bit, a soil pushing rod and a soil cleaning piston, wherein one end of the sampling rod is connected with the first handle, and the other end of the sampling rod is connected with the ring cutter bit; the sampling rod has a hollow internal structures, the soil cleaning piston is inserted into one end of the sampling rod and moves back and forth along the length direction of the sampling rod, the soil pushing rod is inserted into the other end of the sampling rod, and the soil pushing rod is pulled out of the sampling rod during sampling; the sampling rod is provided with a sampling groove convenient for cleaning residual soil through the soil pushing rod, and a soil sample sampled by the sampling rod is pushed through the soil cleaning piston, and is collected. The sampler has the advantages of simple structure, time and labor saving, convenient carrying, safe and convenient soil sampling, guarantee of in situ soil sampling, uniform sampling, reaching of soil sampling requirements.

Description

technical field [0001] The invention relates to an agricultural soil sampling appliance, in particular to a hand-held soil in-situ sampler. Background technique [0002] Most of the soil samplers are semi-circular shovel-shaped samplers, which must be rotated continuously when used, and the soil structure of the soil samples taken out is damaged, and the sampling depth is inaccurate, so that the soil samples obtained cannot truly reflect the soil itself. 's traits. Although the existing T-shaped sampler is more convenient to use, its sampling head has certain insecurity, and its design structure also has certain defects, especially it is difficult to collect soil after sampling. SUMMARY OF THE INVENTION [0003] In view of the above problems existing in the existing soil samplers, the purpose of the present invention is to provide a hand-held soil in-situ sampler. The hand-held soil in-situ sampler realizes the in-situ sampling of soil, the soil structure is not damaged,...
