Description
Technical Field
The invention relates to the technical field of biochemical instruments, in particular to a bacterial liquid coating device.
Background
The bacterial liquid coating is an important link in the process of researching microorganisms, and most of the bacterial liquid coating is finished by manual coating at present. However, manual operation is tedious, time-consuming, laborious, and highly repetitive, and the uniformity of coating on the same batch of flat plates is difficult to maintain consistently. In order to improve the working efficiency of plate coating, reduce the labor intensity of experimenters, ensure the coating consistency of the same batch of plates under the condition of ensuring that each plate can be uniformly coated, and also ensure that the possibility of cross infection between the plates can not be generated, thereby ensuring the accuracy of experimental data, therefore, the operation of coating the plates by using a machine instead of manpower is very important.
So far, the research results for automatic or semi-automatic inoculators at home and abroad are not yet capable of being widely applied, and most of the automatic inoculators available in the market are in the stage of gradual improvement and perfection. Therefore, automatic or semi-automatic plate coating instruments are rarely available in large-scale microbial laboratories at home and abroad, and almost no small-scale and medium-scale microbial laboratories are equipped with automatic or semi-automatic plate coating instruments. So far, a flat coating machine which is suitable for small and medium-sized laboratories and has low cost and good performance does not appear.
The DW-16 type automatic bacteria coating inoculator for the domestic existing flat plate coater is provided with a rotary worktable, and a culture dish is placed on the worktable. When coating, the diluted bacteria is dropped in the center of the culture dish, and the bacteria liquid is dispersed on the surface of the agar by the centrifugal force generated by the rotation of the rotary worktable, thereby achieving the purpose of coating. Such applicators suffer from the following problems: (1) Because the effect of centrifugal force, most fungus liquid can pile up around the culture dish wall under the effect of centrifugal force, leads to too densely when the bacterium grows into the bacterial colony, can't count and observe the bacterial colony characteristic. The significance of the existence of the dilution coating flat plate method is lost. (2) One machine can only complete the coating of one flat plate at the same time, and the efficiency is not high.

The coating mechanism comprises a coating rod 22 arranged on the clamping device 21, a rotary worktable 23, a bearing 24, a second gear 25 and a second module frame 26. A bearing 24 (for example, a 6004 bearing) is fixed at the bottom of a second module frame 26 for providing stable support and is connected with one end of a rotating shaft 27, the rotating shaft 27 can rotate freely, the other end of the rotating shaft 27 passes through the upper part of the second module frame 26 and is fixedly connected with the rotary worktable 23, and the rotating shaft 27 rotates to drive the rotary worktable 23 to rotate; the clamping device 21 is fixed on one side of the rotary table 23 on the upper part of the second module frame 26, so that the coating rod 22 arranged on the clamping device 21 can be placed in a culture dish on the rotary table 23 for coating, and the clamping device 21 can be fixed on the module frame by adopting a threaded fastener; the second gear 25 is in transmission connection with the rotating shaft 27, and when the second gear 25 rotates, the rotating shaft 27 rotates along with the second gear; the second module frame 26 has a second fitting portion 28 for fitting connection with the first fitting portion 14.

Specifically, as shown in fig. 4, the first assembling portion 14 and the second assembling portion 28 are respectively a snap structure corresponding to a male snap structure and a female snap structure. A specific implementation manner is to use a buckle of a concave-convex mechanism, the first assembling portion 14 may be a groove, the second assembling portion 28 may be a protrusion, and of course, the second assembling portion 28 may also be designed as a groove, and the first assembling portion 14 is a protrusion, which is not limited in the present invention. The groove and the protrusion can be matched with the buckle in a mutually splicing manner. Another specific implementation manner is a locking structure, in which the first assembling portion 14 is a locking shaft, the second assembling portion 28 is a locking lock that is locked with the locking shaft, the locking lock rotates around a pin shaft, and can be locked when rotating to the locking shaft, and unlocked when rotating to disengage from the locking shaft. Or, the third specific implementation manner may be a manner of positioning and assembling comb teeth, the first assembling portion 14 and the second assembling portion 28 are staggered comb tooth structures, and the comb tooth head has a clamping portion, so as to perform positioning and limiting functions after the comb tooth structures are mutually spliced and clamped. The above is only a limited example of the snap structure, and other existing snap structures can be used as long as the purpose of connection and fixation can be achieved. In a similar way, no matter which implementation mode is adopted, the effect of assembling and positioning can be realized as long as the male and female buckle structures are met, and the male and female structures of the two module frames can be interchanged in design during design and processing, but the effect of assembling the male and female buckle structures between the module frames is not influenced.
In addition, the first and second module racks 13 and 26 have top and bottom plates, respectively, and the first and second fitting parts 14 and 28 are located on the corresponding top and bottom plates, respectively. For example, for a more secure and stable assembly, the first module frame 13 and the second module frame 26 may be configured as a cubic frame, four brackets may fix a top plate and a bottom plate with threaded fasteners, a gear is disposed in an inner position of the frame, and the cube has a top plate and a bottom plate. The rotating shaft 27 can pass through a rotating hole reserved on the top plate and is fixedly connected with the rotating workbench 23 upwards. In this design, the first assembling portion 14 may be disposed on the first top plate edge of the first module frame 13, and in the case of a concave-convex mechanism, as shown in fig. 1 to 4, a T-shaped concave structure may be disposed on the first top plate edge; a second fitting portion 28 having a T-shaped protrusion structure is provided at a fitting position corresponding to the second top plate edge of the second module frame 26, and similarly, the first bottom plate of the first module frame 13 and the second bottom plate of the second module frame 26 are also provided.
When the two module frames are assembled and combined, the upper and lower groups of T-shaped concave structures and the T-shaped convex structures can be spliced to firmly fix the positions of the two module frames, and at the moment, the first gear 11 and the second gear 25 are meshed and connected. The two groups of assembly parts of the top plate and the bottom plate are assembled, so that the connection between the modules is more stable. Of course, two sets of concave structures can be arranged on the top plate, and two sets of convex structures are correspondingly arranged on the bottom plate, so that the transverse and longitudinal fixing and positioning between the modules are firmer, and the modules are more stable during coating operation.
The special connecting structure design of the bottom plate and the top plate can enable the coating mechanism to be meshed with the coating mechanism or a gear of the power mechanism, and meanwhile, the relative position of the mechanisms is kept fixed.
The chucking device 21 is a hinge mechanism, and the coating rod 22 is provided on the rotary table 23 side via the hinge mechanism. During the use of the coating rod 22, the coating and sterilization operations can be completed by only rotating the coating rod 22 without removing the coating rod 22, thereby greatly reducing the working strength of the user.

In an alternative embodiment, as shown in fig. 1, the first module frame 13 further has a second fitting portion 28 thereon. In order to further expand the assembly scale of the module, a second assembly portion 28 may be provided on the other side of the first module frame 13 of the power mechanism. In this case, the power mechanism may be used by mounting the coating mechanism on the first mounting portion 14 of the first module frame 13, by mounting the coating mechanism on the second mounting portion 28 on the other side, or by mounting both coating mechanisms at the same time, and the first mounting portion 14 and the second mounting portion 28 provided on the first module frame 13 are on both sides of the module frame, so that they do not interfere with each other. That is, the power mechanism can be assembled and used with the second assembling portion 28 of one coating mechanism through the first assembling portion 14 of the power mechanism, and can also be assembled and connected with the first assembling portion 14 of another coating mechanism through the second assembling portion 28 of the other side, so that the infinite extension of the coating mechanisms is realized.
It will be understood by those skilled in the art that the first module frame 13 has a first fitting portion 14 on one side thereof, and another first fitting portion 14 may be further provided on the other side of the first module frame 13. Thus, the first assembling portions 14 on both sides can be assembled with two coating mechanisms having the second assembling portions 28 for assembling purpose, and are not limited in particular.
In an alternative embodiment, coating rod 22 is a metal coating rod. Because the coating rod 22 is made of stainless steel, certain pressure can act on the surface of the culture medium under the action of gravity, and the coating rod is fully contacted with the culture medium through self gravity; the pressure exerted by hands during artificial coating is simulated, but the instability of manual operation can be avoided, so that the coating is more uniform, and the coating effect is better.
Preferably, the length of the coated end of the metal coating rod is less than the diameter of the culture dish. The length of the coating rod 22 is slightly smaller than the diameter of the culture dish and is fixed on the side surface of the module, so that the bacteria liquid can be uniformly coated on the whole agar culture medium only by the rotation of the culture dish, and the bacteria liquid is prevented from being excessively accumulated on the side wall of the culture dish. Furthermore, the length of the coating end of the metal coating rod is determined to be 85% of the diameter of the culture dish through tests, so that bacteria liquid can be prevented from being accumulated on the side wall of the culture dish while being uniformly coated.
