Embodiment Construction
[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0025] The specific embodiment 1 of a kind of soil sampling device of the present invention, as Figure 1 to Figure 7 As shown, the soil sampling device includes a sampling housing 2, a sampling pipe 5 and a separation plate 12 extending in the up and down direction. In the example, the soil channel is the inner cavity of the sampling tube. The side of the sampling tube is provided with a separation plate inlet and outlet 16 for the separation plate 12 to be inserted and taken out. In this embodiment, five separation plates 12 are provided, and nine separation plate inlets and outlets are provided. In other embodiments of the present invention Among them, the number of separation plates and separation plate inlets and outlets can be set according to actual needs, at least one separation plate can be set, and at least one of the separation plates corresp...

The invention relates the field of sampling devices, in particular to a soil sampling method and device. The soil sampling device comprises a sampling shell extending vertically, a soil inlet is formed in the sampling shell, and a soil channel communicated with the soil inlet is formed in the sampling shell. The soil sampling device further comprises separating plates used for carrying out gradient separation on soil in the soil channel, the separating plates are arranged in the sampling shell, and are in movable fit with the soil channel in the cross section direction of the sampling shell or are provided with action ends capable of acting in the cross section direction of the sampling shell, and a separating driving mechanism is further arranged in the sampling shell and is used for driving the separating plates or the action ends of the separating plates to enter or quit the soil channel in the cross section direction of the sampling shell to achieve gradient separation on soil. The problem that at present, the soil sampling efficiency is low is solved.
Description
technical field [0001] The invention relates to the field of sampling devices, in particular to a soil sampling method and device. Background technique [0002] Soil sampling is the basis for studying soil information and an important prerequisite for obtaining soil oxygen content, carbon dioxide content, temperature and humidity information, and various metal indicators. The soil information of different gradients is different due to the distance from the surface of the soil. It is of great significance to study the soil information of different gradients in the same area for exploring the suitability of crops. Traditional soil sampling devices are all single sampling, without gradient separation of soil. Even if the gradients are artificially divided according to the needs after collection, because the soil quality of the collected samples is relatively loose, the standard of classification gradients is not easy to grasp, and the actual separation process is cumbersome, a...
