Description

Technical Field

[0001] The utility model relates to the technical field of soil separators, in particular to a separator for preparing soil samples. Background Art

[0002] There are tens of thousands of soil animals living in the soil. They are an important part of the soil ecosystem. They participate in the decomposition of biological residues and change the soil properties. They are of great significance to the formation and development of the soil and the material circulation and energy flow of the ecosystem.

[0003] The existing separators for soil sample preparation are mainly used to separate animal samples from the soil and complete the collection for subsequent research. The currently commonly used method is to directly illuminate the soil and drive the animals to the preset exit. However, this separation efficiency is low. Many animals inside the soil cannot even feel the light, which is not convenient for efficient outdoor operations. Therefore, we proposed a separator for soil sample preparation.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] A separator for preparing soil samples provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0022] Combination Figure 1-3 As shown, the utility model provides a separator for preparing soil samples, comprising: a body assembly 100 and a separation assembly 200; wherein the body assembly 100 comprises a barrel 110, an end cover 120 disposed on the barrel 110, a light board 130 installed on the end cover 120, a battery 140 installed on the side of the barrel 110, a handle 150 disposed on the end cover 120 and a sample box 160 assembled on the bottom of the barrel 110, the sample box 160 is screwed on the bottom of the barrel 110, and can be replaced in time after a sampling is completed, which is convenient to use.

[0023] The separation assembly 200 is arranged on the cylinder 110, and the separation assembly 200 includes a telescopic rod 210 fixed to the middle of the end cover 120, a stirring rod 220 hinged on the telescopic rod 210, an inner tooth ring 230 arranged on the inner side of the end cover 120, a gear roller 240 meshingly connected to the inner tooth ring 230, a servo motor 250 connected to the gear roller 240 and installed on the cylinder 110, a filter screen plate 260 installed in the middle of the cylinder 110, a separation tube 270 arranged at the bottom of the cylinder 110, a sample outlet 280 opened on the separation tube 270, and a servo motor 250 arranged on the outer side of the separation tube 270 and connected to the sample outlet 280. The side extension plate 290 connected can be used to put the soil on the filter screen plate 260 and then cover the end cover 120 through the separation component 200, so that the inner gear ring 230 is connected to the gear roller 240. At this time, the telescopic rod 210 and the stirring rod 220 fall on the uppermost layer of the soil. During separation, the servo motor 250 drives the gear roller 240 to rotate, thereby causing the end cover 120 to rotate slowly. At this time, the stirring rod 220 rotates on the soil, and the stirring depth gradually increases, so that the soil is slowly broken up, accelerating the animals to pass through the filter screen plate 260 and fall to the bottom of the cylinder 110, and then under the illumination of the light, the animals will crawl into the sample outlet 280 and finally be collected in the sample box 160, which greatly improves the separation efficiency of the samples and facilitates efficient outdoor sampling.

[0024] Specifically, the inner wall of the cylinder 110 is installed with a light board 111 located below the filter screen plate 260, which can further improve the brightness around the separation tube 270, accelerate the movement of the animal sample, and ensure the separation efficiency.

[0025] Furthermore, protective balls 211 are respectively fixed to the ends of the telescopic rod 210 and the stirring rod 220. By setting the protective balls 211 at the ends, the ends of the telescopic rod 210 and the stirring rod 220 can be prevented from causing damage to the animals during rotation. The protective balls 211 can adopt a sponge structure, which is highly practical.

[0026] It should be noted that a pull rod 121 is inserted into the side of the end cover 120, and a positioning block 122 is fixed to the inner end of the pull rod 121. A spring 123 is connected between the positioning block 122 and the end cover 120. An annular groove 124 for clamping the positioning block 122 is provided on the cylinder 110, and a pull ring 125 is connected to the outer end of the pull rod 121. This structure can enable the end cover 120 to be clamped on the cylinder 110 to prevent the end cover 120 from moving upward and detaching when rotating. After the separation is completed, the end cover 120 can be detached by pulling the pull ring 125 outwards with both hands at the same time, which is highly practical.

[0027] Furthermore, a conical umbrella-shaped protective cap 271 is provided on the top of the separation tube 270 . The conical structure can prevent soil from accumulating on the separation tube 270 , while the umbrella-shaped structure can prevent soil from directly blocking the sample outlet 280 , thereby facilitating the entry of animal samples into the separation tube 270 .

[0028] The working principle and use process of the utility model are as follows: first, put the soil on the filter screen plate 260 and then cover the end cover 120, so that the inner gear ring 230 is connected with the gear roller 240. At this time, the telescopic rod 210 and the stirring rod 220 fall on the uppermost layer of the soil. During separation, the servo motor 250 drives the gear roller 240 to rotate, thereby causing the end cover 120 to rotate slowly. At this time, the stirring rod 220 rotates on the soil, and the stirring depth gradually increases, so that the soil is slowly broken up, accelerating the animals to pass through the filter screen plate 260 and fall to the bottom of the cylinder 110, and then under the illumination of the light, the animals will pass through the sample outlet hole 280 and crawl into the separation tube 270, and finally be collected in the sample box 160. After a certain period of time, the sample box 160 can be unscrewed for collection.

[0029] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
