Automatic soil sampler

Abstract

Belonging to the technical field of sampling equipment, the invention specifically discloses an automatic soil sampler, which includes a running frame and a traction connection piece at the front end of the running frame. The running frame is provided with a soil sampler and a soil sampling funnel matching with the soil sampler. The soil sampling funnel is provided with a crank link mechanism, a conveying chain wheel equipped conveying chain is disposed below the soil sampling funnel, and the conveying chain is provided with soil collecting barrels. A soil sampling shovel is arranged below the soil sampler, and is equipped with a soil push rod. The automatic soil sampler provided by the invention has the advantages of reasonable structure, accurate sampling and high degree of automation.

Description

technical field [0001] The invention belongs to the technical field of sampling equipment, relates to a sampling machine, in particular to an automatic soil sampling machine. Background technique [0002] In recent years, my country's agricultural science and technology has developed rapidly, especially in the field of soil research and analysis. The country and enterprises have invested a lot of financial resources and manpower to develop the field of soil research, and soil sampling is a pre-procedure for soil research and analysis. Gaining importance. How to conduct reasonable and efficient soil sampling and manufacture various mechanical equipment required for soil sampling has become an important issue in the development of agriculture. [0003] Soil samplers are mostly divided into handheld portable and motor vehicle traction. The handheld portable soil sampler has a small sampling volume and a small sampling range. If you want to sample a large area of ​​farmland soil...

Problems solved by technology

[0003] Soil samplers are mostly divided into handheld portable and motor vehicle traction. The handheld portable soil sampler has a small sampling volume and a small sampling range. If you want to sample a large area of ​​farmland soil, it will inevitably require a lot of manpower and material resources, and the cost is high. The work efficiency is low; the motor vehicle towed sampling equipment is pulled by the motor vehicle, the sampling volume is large, the sampling range is large and the work efficiency is high, but there are many problems; for example, the automation degree of the sampling machine is not high, the operation is complicated, and the user needs to replace it manually Sample collection device; if the obtained samples need to manually mark the sampling position, it is easy to make mistakes and affect the accuracy of later soil analysis

However, some traction samplers with a high degree of automation have problems such as complex design, high equipment manufacturing costs, and high requirements for users, which is not conducive to large-scale promotion and use and cost control.
