Description

TECHNICAL FIELD

[0001] The utility model relates to soil detection device technical field, concretely point to a soil detection is with rotating shake even device. BACKGROUND

[0002] Soil detection has extremely important significance in agricultural production, environmental monitoring, geological research and many other fields. By detecting various indexes of soil, key data support can be provided for reasonable fertilization, soil improvement, pollution assessment and management, etc., so as to realize sustainable development of agriculture, environmental protection and rational utilization of resources.

[0003] In the soil detection process, in order to ensure the uniformity and representativeness of the detection sample, a shaking device is often used to mix the soil and the detection reagent fully. The traditional soil detection shaking device generally adopts a simple rotary structure, mainly composed of a motor, a support and a shaking barrel fixed on the support. In work, the motor drives the shaking barrel to do circular motion around a single axis, so as to realize the shaking operation of the soil and reagent mixture in the barrel.

[0004] However, this traditional shaking device has obvious defects. In terms of shaking effect, since it only uses single rotary motion mode, the mixing of soil and reagent in the barrel is not sufficient enough, and local concentration difference is easy to appear. In addition, the traditional shaking barrel lacks a mechanism for dividing the mud particles. When the soil and reagent are mixed to form mud-like substances, similar to the phenomenon of a large number of dry powder particles wrapped in wet paste when flour is dissolved in water, these particles are difficult to be uniformly dispersed in the mixed liquid simply by shaking of the traditional shaking device without special division and crushing, which leads to difficulty in achieving ideal uniformity of the detection sample.

[0029] The utility model will be further described in detail below in combination with the drawings.

[0031] In the embodiment, as a preferred technical scheme, the belt drive assembly comprises a belt pulley one 11 fixedly arranged on the bottom of the transmission shaft 7, and a belt pulley two 12 fixedly connected with the rotating shaft of the bottom of the shaking barrel 4, and the belt pulley one 11 and the belt pulley two 12 are connected through a belt 13.

[0032] In the embodiment, as a preferred technical scheme, the elastic expansion assembly 9 comprises an insertion cavity 14 fixedly arranged on the inner side surface of the sealing cover 5, a telescopic rod 15 movably arranged in the insertion cavity 14, a limiting plate 16 fixedly arranged at the end of the telescopic rod 15 inserted into the insertion cavity 14, a reset spring 17 arranged between the limiting plate 16 and the top surface of the insertion cavity 14, and the homogenizing plate 10 fixedly arranged at the lower end of the telescopic rod 15.

[0033] The working principle of the rotating and uniform-shaking device for soil detection is as follows: after the motor 3 is started, the outer frame 2 is driven to rotate around the rotating shaft 20 in the support base 1. At the same time, the transmission shaft 7 on the outer side of the outer frame 2 rotates under the meshing action of the bevel gear two 8 and the bevel gear one 6 fixedly arranged on the inner side surface of the support base 1, and then drives the uniform-shaking barrel 4 to rotate on the inner bottom surface of the outer frame 2 through the belt transmission assembly. In this way, the uniform-shaking barrel 4 realizes double rotary motion, so that the internal soil and the reagent are fully mixed. In this process, the elastic expansion assembly 9 and the homogenizing plate 10 in the sealing cover 5 also play a role. Due to the interaction of the centrifugal force and the elastic force of the reset spring 17, the homogenizing plate 10 reciprocates, when rotating at high speed, the centrifugal force is greater than the elastic force, the reset spring 17 is compressed, and the homogenizing plate 10 moves towards the sealing cover 5; when the rotation speed slows down, the centrifugal force is less than the restoring force of the reset spring 17, and the homogenizing plate 10 moves in the opposite direction. By controlling the motor 3 to run at variable speed, the homogenizing plate 10 is continuously reciprocated, so that the annular frame 18 and the internally crosswise arranged thin rods 19 can effectively divide the material, and further improve the uniformity of mixing.

[0034] The working process of the rotating and uniform-shaking device for soil detection is as follows:

[0035] 1. First, the soil sample to be detected and the corresponding detection reagent are placed in the uniform-shaking barrel 4, and then the sealing cover 5 is threadedly connected to the upper end of the uniform-shaking barrel 4 to ensure good sealing.

[0036] 2. The motor 3 is started, and the motor 3 drives the outer frame 2 to start rotating around the rotating shaft 20, and the rotation of the outer frame 2 drives the transmission shaft 7 to rotate around the rotating shaft 20 as the center, and the transmission shaft 7 is driven to rotate by the meshing transmission of the bevel gear two 8 and the bevel gear one 6, and then the power is transmitted to the belt transmission assembly.

[0037] 3. The belt pulley one 11 in the belt transmission assembly rotates under the drive of the transmission shaft 7, drives the belt pulley two 12 fixedly connected with the rotating shaft at the bottom of the uniform-shaking barrel 4 to rotate through the belt 13, so that the uniform-shaking barrel 4 also starts to rotate, realizes double rotary motion, and preliminarily shakes and mixes the materials in the barrel.

[0038] 4. With the change of the rotation speed of the shaking barrel 4, the homogenizing plate 10 starts to reciprocate under the interaction of the centrifugal force and the elastic force of the reset spring 17. The motor 3 runs at variable speed, when rotating at high speed, the centrifugal force makes the homogenizing plate 10 move towards the sealing cover 5, compressing the reset spring 17; when the rotation speed decreases, the restoring force of the reset spring 17 makes the homogenizing plate 10 move reversely, the ring frame 18 and the thin rod 19 of the homogenizing plate 10 split and crush the particles in the material, further promoting the uniform mixing of the material.

[0039] 5. After a certain time of shaking operation, the motor 3 is turned off, the sealing cover 5 is unscrewed, and the shaken soil detection sample is taken out for subsequent detection and analysis.

[0040] The above describes the present application and its embodiments, which are not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired by it, without departing from the creative purpose of the present application, similar structural modes and embodiments can be designed without creativity, which should belong to the protection scope of the present application.
