Description

Technical Field

[0001] The utility model relates to the technical field of endophyte isolation, in particular to an isolation device for crop endophytes. Background Technique

[0002] The isolation of endophytes is a complex process involving aseptic operation and microbial culture techniques. Its main purpose is to isolate microbial strains with specific functions or activities from crops. When performing isolation, first, a cutting mechanism is needed to cut and separate the roots and stems of crops in a selected size within a specified area, and then a series of operations such as disinfection, inoculation, and purification are carried out on the cut crop samples.

[0003] Some existing cutting mechanisms use a telescopic rod to drive a blade to cut crops. After the first cut, the crop needs to be moved a certain position, and then the blade is used to cut the crop a second time, so as to obtain a crop sample with a selected size within a specified area of the crop. However, since it needs to be cut twice, the cutting efficiency is not good. At the same time, using straight cutting, the cutting effect is limited, and the roots and stems of some crops have high toughness and are not easy to cut off. Content of the Utility Model

Specific embodiments

[0020] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] Please refer to Figure 1-6 , the present utility model provides a technical solution: a separation device for endophytic bacteria of crops, including a frame body 1, two fixing mechanisms 2 are installed on the frame body 1, an adjusting mechanism 3 is connected to the frame body 1, the lifting end of the adjusting mechanism 3 is connected to a cutting mechanism 4, the fixed end of the cutting mechanism 4 is connected to the frame body 1, the adjusting mechanism 3 includes a connecting frame 31, two connecting frames 31 are connected to the surface of the frame body 1, a motor 32 is installed on the surface of the connecting frame 31, the output end of the motor 32 penetrates through the connecting frame 31 and is rotatably connected to the connecting frame 31, the output end of the motor 32 is connected to a bidirectional reciprocating screw rod 33, one end of the bidirectional reciprocating screw rod 33 is rotatably connected to the connecting frame 31, two sliding tables 34 are threadedly connected to the surface of the bidirectional reciprocating screw rod 33, a guide rod 35 is fixedly connected between the two connecting frames 31, the guide rod 35 penetrates through the sliding table 34 and is slidably connected to the sliding table 34, a sliding rod 36 penetrating through it is slidably connected to the surface of the sliding table 34, the lower end of the sliding rod 36 is connected to a first slider 37, a telescopic rod 38 is installed at the lower end of the frame body 1, the moving end of the telescopic rod 38 penetrates through the through hole opened on the surface of the frame body 1 and is connected to a first slide rail 39, the first slider 37 is placed inside the first slide rail 39 and is slidably connected to the first slide rail 39, and the sliding rod 36 is connected to the lifting and cutting part of the cutting mechanism 4.

[0022] In this implementation scheme, first place the crops on the rack 1, place the area to be cut in the middle, and then use the fixing mechanism 2 to tighten and fix the crops. After fixing, start the motor 32. Due to the rotation of the output end of the motor 32, the bi-directional reciprocating screw rod 33 is driven to rotate, and then cooperate with the guide rod 35 to make the two sliding tables 34 approach or move away from each other, and at the same time drive the two sliding rods 36 to move. The two first sliders 37 slide inside the first slide rail 39, thereby driving the two lifting and cutting parts of the cutting mechanism 4 to approach or move away from each other. When the distance between the two sliding rods 36 is adjusted to the selected distance, start the telescopic rod 38, thereby driving the first slide rail 39 to move downward, driving the two sliding rods 36 to move downward through the two first sliders 37, and the sliding rod 36 slides downward on the surface of the sliding table 34, so that the two lifting and cutting parts of the cutting mechanism 4 move downward, so that the roots of the crops can be cut and separated with a selected size within a specified area. Therefore, the cutting and separation can be completed at one time, improving the cutting efficiency of the cutting work.

[0023] Specifically, scale lines 391 are provided on the surface of the first slide rail 39.

[0024] In this embodiment, the user can know the cutting distance by observing the scale of the scale lines 391 corresponding to the two lifting and cutting parts of the cutting mechanism 4.

[0025] Specifically, a first spring 392 is wound around the surface of the sliding rod 36. One end of the first spring 392 is connected to the sliding rod 36, and the other end of the first spring 392 is connected to the sliding table 34.

[0026] In this embodiment, when the sliding rod 36 moves up and down, due to the elastic force of the first spring 392, the sliding rod 36 moves up and down more smoothly.

[0027] Specifically, the cutting mechanism 4 includes a lifting plate 41. The surface of the sliding rod 36 is connected with a lifting plate 41. A chute 42 is opened on the lower surface of the lifting plate 41. A second slider 43 is slidably connected inside the chute 42. The lower end of the second slider 43 is connected with a cutting knife 47. A rotating rod 45 passing through it is rotatably connected to the surface of the lifting plate 41. A reciprocating screw rod 44 is rotatably connected inside the chute 42. The reciprocating screw rod 44 passes through the second slider 43 and is threadedly connected to the second slider 43. One end of the rotating rod 45 extending into the chute 42 is connected to the reciprocating screw rod 44. One end of the rotating rod 45 is connected with a meshing wheel 46. The surface of the rack 1 is connected with a second slide rail 48. Two third sliders 49 are slidably connected inside the second slide rail 48. The upper ends of the third sliders 49 are connected with a meshing plate 491. The meshing plate 491 meshes with the meshing wheel 46. One end of the third slider 49 is connected with a second spring 492. The second spring 492 is placed inside the second slide rail 48, and one end of it is connected to the second slide rail 48.

[0028] In this embodiment, when the sliding rod 36 moves downward, it drives the lifting plate 41 to move downward. Through the rotating rod 45, the meshing wheel 46 is driven to move downward. Since the meshing wheel 46 meshes with the meshing plate 491, the meshing wheel 46 rolls downward on the surface of the meshing plate 491. Thus, while driving the rotating rod 45 to move downward, it also rotates, and further drives the reciprocating lead screw 44 to rotate relative to the lifting plate 41. Furthermore, it drives the second slider 43 to reciprocate inside the chute 42, and further drives the cutting knife 47 to perform a reciprocating motion to achieve the sawing effect, thereby improving the cutting effect. At the same time, when the distance between the two lifting plates 41 changes, due to the movement of the meshing wheel 46, the meshing plate 491 is squeezed, so that the meshing plate 491 moves, and the third slider 49 slides inside the second slide rail 48. And since the second spring 492 is always in a compressed state, it can be ensured that no matter how the meshing wheel 46 moves, the meshing wheel 46 is always in a state of mutual contact and extrusion with the meshing plate 491.

[0029] Specifically, an indicating block 493 is connected to the lower end of the lifting plate 41, and the indicating block 493 is arranged corresponding to the cutting knife 47.

[0030] In this embodiment, when the lifting plate 41 moves left and right, it drives the indicating block 493 to move in front of the scale line 391. By observing the scales specified by the two indicating blocks 493, the cutting distance can be known, which is convenient for the user to observe the indicated distance.

[0031] Specifically, the fixing mechanism 2 includes a square tube 21. The surface of the frame body 1 is connected with the square tube 21. A fastening threaded rod 22 passing through it is threadedly connected to the surface of the square tube 21. One end of the fastening threaded rod 22 extending into the square tube 21 is rotatably connected with an arc-shaped plate 23. A limiting rod 24 passing through it is slidably connected to the surface of the square tube 21, and the lower end of the limiting rod 24 is connected with the arc-shaped plate 23.

[0032] In this embodiment, the user passes the crop through the square tube 21, and then rotates the fastening threaded rod 22. Using the thread drive and cooperating with the limiting rod 24, the limiting rod 24 slides on the surface of the square tube 21, so that the arc-shaped plate 23 moves downward, and then the crop is squeezed and fixed.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
