Description

Technical Field

[0001] This invention belongs to the field of bacterial isolation and purification technology, and specifically relates to a streak plate device for bacterial purification. Background Technology

[0002] In nature, different types of microorganisms often coexist. Therefore, before humans mastered the technology of strain isolation, the strains used in fermentation industries such as brewing, sauce making, and vinegar making were all mixed strains. With the continuous development of science and technology and people's proficiency in strain isolation technology, more and more strains have been isolated, purified, and cultured, facilitating the research of microbial resources.

[0003] Commonly used separation methods in the laboratory include plating, streak plating, and dilution shaker method. The simplest separation method is streak plating, but manual operation can damage the culture medium due to varying streak strength and uniformity. When a large number of streaks are required, the work efficiency is low, affecting the experimental progress. Utility Model Content

[0004] The purpose of this invention is to provide a streaking device for bacterial purification, aiming to solve the problems existing in the prior art described above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A streak-marking device for bacterial purification includes a support, a conveyor belt, a controller, a streak-marking bar, and a streak-marking mechanism. The conveyor belt passes through the support and is positioned below it. A horizontal slide bar is mounted on the top of the support, with its length direction perpendicular to the length direction of the conveyor belt. The streak-marking mechanism includes a housing and a connector. The top of the housing passes through the slide bar, and the bottom is open. A first rack and a slide rail are vertically mounted on the inner sidewall of the housing. The connector is equipped with a drive motor, the output end of which has a gear that meshes with the first rack. The connector has a first groove through which the first rack passes and a second groove that mates with the slide rail. The streak-marking bar is detachably connected to the connector. The controller is mounted on the support and is electrically connected to both the drive motor and the conveyor belt.

[0007] The petri dish is placed on a conveyor belt and transported to the bottom of the scribing device. The controller controls the drive motor to rotate, and the drive motor drives the connecting part to move downward along the slide rail on the side wall of the shell. The scribing bar moves to the petri dish and completes the scribing as the conveyor belt moves. The scribing bar and the scribing device are detachably connected, which facilitates the replacement of the scribing bar.

[0008] Furthermore, the bottom of the connector is provided with a recessed portion for engaging with the scribing bar. The scribing bar is inserted along the recessed portion and engaged with the connector, thereby completing the connection between the scribing bar and the scribing device.

[0009] Furthermore, the connector includes a first connector and a second connector connected by a spring. The drive motor is disposed on the top surface of the first connector, and the bottom surface of the second connector has a recess for engaging with the streak. By engaging the streak with the second connector, the streak makes elastic contact with the culture dish, improving the streak quality.

[0010] Furthermore, the top of the scribing bar has a horizontal protrusion, and the recessed portion is adapted to the shape of the top of the scribing bar. The recessed portion is provided with a locking part that engages with the protrusion. When the scribing bar is inserted into the recessed portion and rotated, the protrusion engages with the locking part provided in the recessed portion.

[0011] Furthermore, the slide bar is provided with a limiting strip along its length, and the housing is provided with a limiting groove that mates with the limiting strip. The limiting strip is used to improve the stability of the connection between the housing and the slide bar, and to keep the housing in a vertical position.

[0012] Furthermore, a second rack is provided along the length of the slide bar's sidewall, a motor is installed inside the housing, and a gear meshing with the second rack is provided at the motor's output end. The motor is electrically connected to the controller, and a limiting strip is provided at the top of the slide bar. The controller controls the housing to move longitudinally along the slide bar, coordinating with the rotation of the transmission belt, allowing the scribing device to scribble lines on the petri dish both longitudinally and laterally without the need for operator intervention.

[0013] Furthermore, the conveyor belt is equipped with a limiting ring for placing the culture dish. The limiting ring is used to prevent the culture dish from sliding on the surface of the conveyor belt during the streaking process, thereby affecting the streaking quality.

[0014] Furthermore, four sliding rods are evenly spaced. These four sliding rods, along with four sets of marking devices, improve marking efficiency.

[0015] Compared with the shortcomings and deficiencies of existing technologies, this utility model has the following beneficial effects:

[0016] 1. This utility model provides a streaking device for bacterial purification. A streaking rod is placed on the streaking device, and the streaking device is moved vertically by a controller until the streaking rod contacts the culture dish. The controller also controls the conveyor belt to rotate, thereby completing the streaking. The streaking is precise and efficient.

[0017] 2. The controller controls the scribing device to slide along the slide bar, which, in conjunction with the rotation of the conveyor belt, allows the scribing rod to scribble lines on the petri dish in both the horizontal and vertical directions. This eliminates the need for manual scribing and effectively improves the standard and quality of the scribing.

[0018] 3. Multiple sliding rods are evenly spaced on the support, and multiple sets of marking devices are set accordingly to improve marking efficiency. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] Example 1

[0032] Reference Figure 1 and Figure 2 A streaking device for bacterial purification includes a conveyor belt 3 for transporting culture dishes to be streaked, a support 1 for fixing a streaking device 2, a streaking device 2 for fixing a streaking rod 4 and driving the streaking rod 4 to move vertically, working in conjunction with the conveyor belt 3 to complete the streaking, and a controller for controlling the movement of the streaking device 2 to ensure the accuracy of the streaking.

[0033] The conveyor belt 3 is set below the support 1. The petri dish is placed on the conveyor belt 3 and transported to the support 1 via the conveyor belt 3. After marking is completed, the petri dish is transported out of the support 1.

[0034] The support frame 1 adopts a frame structure and is rectangular in shape. It includes a fixed frame and support columns located at the bottom of the fixed frame. A slide bar 11 is horizontally installed inside the fixed frame, and the length direction of the slide bar 11 is perpendicular to the length direction of the conveyor belt 3.

[0035] Reference Figure 3 The marking device 2 is slidably connected to the support 1 via the slide rod 11. The marking device 2 includes a housing 21, which has a rectangular horizontal cross-section and is cylindrical in shape. The bottom of the housing 21 is open downwards, and the top is fitted onto the slide rod 11. A first toothed rack 211 is vertically arranged on the inner side wall of the housing 21. A connecting member 22 is horizontally arranged and movably connected inside the housing 21. Specifically, the size of the connecting member 22 is adapted to the cross-sectional size of the housing 21. A drive motor 221 is arranged on the top of the connecting member 22. (Refer to...) Figure 4 The output end of the drive motor 221 is provided with a gear that meshes with the first rack 211. (Refer to...) Figure 5 The connector 22 is provided with a first groove 222 through which the first rack 211 passes. The connector 22 and the housing 21 are slidably connected by a convex-concave fit. Specifically, a track 212 is vertically arranged on the inner side wall of the housing 21, and the connector 22 is provided with a second groove 223 that matches the track 212 to ensure that the connector 22 moves vertically along the housing 21. Preferably, two sets of tracks 212 are arranged opposite to each other inside the housing 21 to improve the stability of the movement of the connector 22.

[0036] Reference Figure 6 and Figure 7 The marking bar 4 and the connector 22 are detachably connected. The upper part of the marking bar 4 is horizontally provided with a protrusion, and the bottom surface of the connector 22 is provided with a recess 224. The shape and size of the recess 224 are adapted to the marking bar 4. The upper part of the recess 224 is provided with a locking part 2241 for locking the protrusion of the marking bar 4. The marking bar 4 is inserted into the recess 224 along the bottom surface of the connector 22. The marking bar 4 is rotated, and the protrusion rotates horizontally to the locking part 2241, thereby fixing the marking bar 4 and the connector 22.

[0037] The controller is mounted on the support 1 and is electrically connected to the drive motor 221 and the transmission belt 3. The controller controls the connector 22 to drive the scribing rod 4 to move vertically, and controls the transmission belt 3 to rotate, thereby driving the scribing rod 4 to scribble horizontally on the surface of the petri dish. Vertical scribing can be completed by the experimenter moving the scribing device 2 along the slide bar 11 on the support 1.

[0038] To ensure that the housing 21 remains horizontal as it moves along the slide bar 11, a limiting strip 111 is provided on the side wall of the slide bar 11, and a limiting groove 214 is provided on the housing 21 to fit the limiting strip 111.

[0039] A petri dish typically requires multiple streaking operations. The support 1 is equipped with multiple sliding rods 11, and correspondingly, multiple streaking devices 2, to improve streaking efficiency. Preferably, the support 1 has four sliding rods 11, each equipped with four streaking devices 2.

[0040] To prevent the petri dishes from sliding on the surface of the conveyor belt 3 during the streaking process, limiting rings 5 ​​are set at intervals on the conveyor belt 3. The petri dishes are placed in the grooves formed by the limiting rings 5, which effectively prevents the petri dishes from moving and ensures the smooth progress of the experiment.

[0041] Example 2

[0042] Example 2 is a further improvement on Example 1, and the differences between Example 1 and Example 1 are as follows:

[0043] Reference Figure 8 The connector 22 includes a first connector 225 and a second connector 226. Both the first connector 225 and the second connector 226 are provided with a first groove 222 through which the first rack 211 passes and a second groove 223 that is slidably connected to the housing 21. The drive motor 221 is disposed on the top surface of the first connector 225. The bottom of the second connector 226 is provided with a recess 224 that is detachably connected to the scribing rod 4. The first connector 225 and the second connector 226 are connected by a spring 227, which is located at the center of the bottom surface of the first connector 225 and the top surface of the second connector 226. This allows the scribing rod 4 to make elastic contact with the culture dish during the scribing process, improving the scribing quality.

[0044] Example 3

[0045] Example 3 is a further improvement on Example 1, and the differences between Example 1 and Example 1 are as follows:

[0046] Reference Figure 9 and Figure 10 To further improve the line marking efficiency, the slide bar 11 on the bracket 1 is equipped with a second rack 112, and a motor 213 is installed inside the housing 21. The output end of the motor 213 is set in the gear meshing with the second rack 112, and the motor 213 is electrically connected to the controller.

[0047] The marking device 2 moves longitudinally along the slide bar 11 under the control of the controller. The marking device 2 works with the conveyor belt 3 to mark lines laterally, eliminating the need for manual operation and improving marking efficiency and quality.

[0048] This invention provides a streak penetrating device for bacterial purification. The top of the support is slidably connected to the streak penetrating device via a sliding rod. The streak penetrating device is detachably connected to a streak penetrating rod. A conveyor belt for transporting culture dishes is set at the bottom of the support. The controller controls the streak penetrating device to move the streak penetrating rod vertically to the culture dish and move with the conveyor belt to complete the streak penetrating. In a further improved technical solution, the controller controls the streak penetrating device to move longitudinally along the sliding rod, so that the streak penetrating process does not require manual operation. The controller controls the longitudinal and transverse streak penetrating of the streak penetrating rod, which significantly improves the streak penetrating efficiency and quality.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
