Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil sampling, in particular to a sampling machine for soil carbon emission monitoring. Background Technique
[0002] In recent years, the agricultural science and technology in China has developed rapidly, especially in the field of soil research and analysis. As a pre-procedure for soil research and analysis, soil collection and sampling have received increasing attention. How to conduct reasonable and efficient soil sampling and manufacture various mechanical equipment required for soil sampling has become an important issue in agricultural development.
[0003] A soil boring rig is a device used to collect soil samples, usually consisting of parts such as a drill bit, drill pipe, and soil sampler. Its working principle is to drill the soil into the drill bit by rotating or impacting, and then export the soil sample from the drill pipe. The following is an introduction to the structures of some common soil boring rigs: Drill bit: The drill bit is a key component of the soil boring rig and is used to drill into the soil. It usually has a sharp shape and a hard material to ensure that it can smoothly drill into the soil. The type and size of the drill bit will be selected according to different application scenarios and soil types. Drill pipe: The drill pipe is a component connecting the drill bit and the soil sampler and is used to transmit power and convey soil samples. The drill pipe usually has a certain length and strength to ensure that it can meet the soil sampling requirements at different depths. Soil sampler: The soil sampler is a component used to collect soil samples and is usually located at the bottom of the drill pipe. The type and size of the soil sampler will also be selected according to different application scenarios and soil types. Power system: A soil boring rig usually requires a power system to drive the drill bit to rotate or impact. The power system can be electric, hydraulic, or gasoline-driven, depending on the type and application scenario of the soil boring rig. Control system: A soil boring rig is usually equipped with a control system to control parameters such as the rotation speed of the drill bit, impact frequency, and drilling depth.
[0004] Most of the existing soil sampling machines are divided into handheld portable and motor vehicle traction types. When using a handheld portable soil sampling machine, the drill bit is prone to deviation, resulting in the samples taken not meeting the detection requirements; while when using a motor vehicle traction type to tow the sampling equipment by a motor vehicle, it is easy to damage the crops planted in the farmland, causing a large amount of economic losses.
