Description

Technical Field

[0001] The present application relates to the technical field of gene extraction, and specifically relates to a biological gene extraction device. Background Technique

[0002] Gene extraction, also known as genomic DNA extraction, is a process of extracting DNA sequences from organisms, aiming to study and analyze the genetic information of organisms. These DNA molecules contain the genetic information of organisms and are the blueprints of life activities.

[0003] For example, a multi-type biological gene extraction device disclosed in a Chinese utility model patent with the publication number "CN216296421U". In this utility model, a grinding roller is placed in a box body, the card slot on the sleeve is snapped into the card block, and at the same time, the annular plate is snapped into the annular groove. Then, the biological sample to be ground is placed in the box body, and the motor is started by an external power supply. The output shaft of the motor drives the sleeve to rotate through the rotating shaft, so that the sleeve drives the grinding roller to rotate through the round shaft, and the biological sample is ground by the first grinding block and the second grinding block. The rotating shaft also drives the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear and drives the transmission shaft to rotate, so that the transmission shaft drives the fourth bevel gear to rotate through the third bevel gear. The fourth bevel gear drives the intermittent gear to rotate through the movable shaft. The intermittent gear meshes with the tooth block and drives the movable plate to move downward, and at the same time, the spring is compressed. When the intermittent gear disengages from the tooth block, the top plate is driven by the spring to bounce the biological sample upward and enter between the first grinding block and the second grinding block again.

[0004] In the above patent, the biological sample can be ground multiple times to improve the extraction effect. However, after the device is used, the ground biological sample falls onto the movable plate, and it is difficult to efficiently take out the biological sample from the device, which easily affects the working efficiency of subsequent gene extraction.

[0031] The present application will be further elaborated in detail below through the drawings and embodiments.

[0032] Referring to Figure 1 and Figure 2 , an embodiment of the present application provides a biological gene extraction device, including a box body 1. Above the box body 1, there is a grinding mechanism 2 for grinding biological samples. Inside the box body 1, there is an adjustment mechanism 3. The adjustment mechanism 3 includes a connecting plate 301 and a placement box 302. The connecting plate 301 is slidably connected to both sides of the inner wall of the box body 1. The placement box 302 is fixedly installed on the upper surface of the connecting plate 301 and penetrates the upper surface of the connecting plate 301. Through the grinding mechanism 2, by starting the first electric telescopic rod 303 and the second electric telescopic rod 305 to retract and stretch respectively, the distance between the bottom end of the inner wall of the placement box 302 and the grinding block 204 can be reduced to more effectively grind the biological sample. After the initial grinding is completed, start the second electric telescopic rod 305 to retract and then stretch to make the connecting plate 301 and the placement box 302 fall and then rise, so that the biological samples inside the placement box are evenly distributed, and then continue to grind the biological samples by the grinding block 204 for the second time. After removing the box cover 201 from the device, pulling the connecting plate 301 can take it and the placement box 302 out of the device to pour out the biological samples and clean the placement box 302. Through the adjustment mechanism 3, by sliding the positioning block 202 into the inner wall of the box body 1, the box cover 201 can be covered on the box body 1. At the same time, the first electric telescopic rod 303 and the pressure plate 304 press the connecting plate 301 to limit its position. Then start the motor 207. The motor 207 drives the rotating shaft 205 to rotate, making the belt 206 rotate, and then making all the rotating shafts 205 rotate simultaneously to drive the connecting rod 203 and the grinding block 204 to rotate to grind multiple groups of biological samples simultaneously.

[0033] Referring to Figure 3 and Figure 4 , in one aspect of this embodiment, a positioning block 202 is slidably connected to the inner wall surface of the box body 1, and a box cover 201 is fixedly installed on the upper surface of the positioning block 202.

[0034] A connecting rod 203 is rotatably connected to the lower surface of the box cover 201. A grinding block 204 is fixedly installed at one end of the connecting rod 203. A rotating shaft 205 is rotatably connected to the bottom end of the inner wall of the box body 1. The connecting rod 203 is fixedly connected to the rotating shaft 205.

[0035] A belt 206 is slidably connected to the surface of the rotating shaft 205. A motor 207 is fixedly installed on the upper surface of the box cover 201. The output shaft of the motor 207 is fixedly connected to the rotating shaft 205. By starting the first electric telescopic rod 303 and the second electric telescopic rod 305 to retract and extend respectively, the distance between the bottom end of the inner wall of the placement box 302 and the grinding block 204 is reduced to grind the biological sample more effectively. After the initial grinding is completed, start the second electric telescopic rod 305 to retract and then extend to make the connecting plate 301 and the placement box 302 fall and then rise, so that the biological samples inside the placement box are evenly distributed, and then the grinding block 204 continues to grind the biological sample for the second time. After removing the box cover 201 from the device, pull the connecting plate 301 to remove it and the placement box 302 from the device, pour out the biological sample, and clean the placement box 302.

[0036] Refer to Figure 1 and Figure 2 In one aspect of this embodiment, a first electric telescopic rod 303 is fixedly installed on the lower surface of the box cover 201. A pressing plate 304 is fixedly installed at one end of the first electric telescopic rod 303.

[0037] A second electric telescopic rod 305 is fixedly installed at the bottom end of the inner wall of the box body 1. A top plate 306 is fixedly installed at one end of the second electric telescopic rod 305. By sliding the positioning block 202 into the inner wall of the box body 1, the box cover 201 is covered on the box body 1. At the same time, the first electric telescopic rod 303 and the pressing plate 304 press the connecting plate 301 to limit its position. Then start the motor 207. The motor 207 drives the rotating shaft 205 to rotate, causing the belt 206 to rotate, and then all the rotating shafts 205 rotate simultaneously, driving the connecting rod 203 and the grinding block 204 to rotate to grind multiple groups of biological samples simultaneously.

[0038] In this solution, all electrical equipment is powered by an external power supply.

[0039] Working principle: When using the device, the device should first be placed at the designated position. Then, after putting a biological sample into the placement box 302, it is placed into the box body 1. The positioning block 202 is slid into the inner wall of the box body 1 so that the box cover 201 covers the upper part of the box body 1. At the same time, the first electric telescopic rod 303 and the pressing plate 304 press the connecting plate 301 to limit its position. Then, the motor 207 is started. The motor 207 drives the rotating shaft 205 to rotate, causing the belt 206 to rotate, and then all the rotating shafts 205 rotate simultaneously to drive the connecting rod 203 and the grinding block 204 to rotate to grind multiple groups of biological samples simultaneously. During the grinding process, the first electric telescopic rod 303 and the second electric telescopic rod 305 are started to retract and extend respectively, reducing the distance between the bottom end of the inner wall of the placement box 302 and the grinding block 204 to grind the biological samples more effectively. After the initial grinding is completed, the second electric telescopic rod 305 is started to retract and then extend, causing the connecting plate 301 and the placement box 302 to fall and then rise, so that the biological samples inside the placement box are evenly distributed, and then the grinding block 204 continues to perform secondary grinding on the biological samples. After the grinding is completed, pulling the handle on the upper surface of the box cover 201 can remove the box cover 201 from the device for cleaning. Pulling the connecting plate 301 can remove it and the placement box 302 from the device to pour out the biological samples and clean the placement box 302.
