Fruit tree root system soil sampling device

Abstract

The invention discloses a fruit tree root system soil sampling device, and relates to the technical field of agricultural equipment. The device comprises a box body, a fixed plate arranged in the box body, two groups of lifting mechanisms arranged between the fixed plate and the box body, a sampling barrel connected to the middle of the bottom surface of the fixed plate, and a separating mechanism arranged at the bottom of the sampling barrel; the top of an annular base is fixed above the sampling barrel; an annular bottom plate is arranged on the inner wall of the annular base, and a first annular groove is formed in the annular bottom plate; an annular top plate is arranged on the inner wall of the annular base; a first motor is fixed on the annular bottom plate, and an output shaft of the first motor is vertically upward; a first gear is fixedly sleeved on an output shaft of the first motor; a second gear is meshed with the first gear; and a plurality of blades are arranged, the bottoms of blade handles are connected with the annular bottom plate through first rotating shafts, and the tops of the blade handles are connected with the second gear through second rotating shafts. The sampling device has the advantages that the separating mechanism can cut soil open, and the situation that soil at the bottom falls off when the sampling barrel is pulled out, and collected samples are incomplete is avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a sampling device for fruit tree root soil. Background technique [0002] Plant root systems are often sampled in agricultural scientific research. Research on plant root systems and the native soil in which they grow can help researchers better understand the growth of plants and help researchers further monitor the growth of crops; on the other hand, native soil samples are useful for measuring Soil water and air conductivity related parameters are also very important. The root system is also the main organ for fruit trees to absorb nutrients and water. The absorption of nutrients by the roots of fruit trees is the core of the nutrition of fruit trees. If there is a problem with the root system of fruit trees, the yield will be reduced if it is light, and the harvest will be dead if it is serious. The growth and management of the underground part of fruit trees...

Problems solved by technology

[0004] The present invention provides a fruit tree root soil sampling device, which is used to solve the problem that in the prior art, when the soil sampling device is pulled out, the soil collected at the bottom part is easily mixed with other soil collected in the soil sampling device. Soil phase separation, resulting in incomplete soil samples collected, causing inconvenience to subsequent testing
