Commonly used grinding equipment includes small grinders, vibratory grinders, tissue grinders, etc. Existing small grinders are usually used frequently in biological laboratories. When grinding crop seeds, the grinder cannot adjust the grinding gap according to the size of the seeds, resulting in damage to the seeds during grinding, affecting the experimental data. Moreover, the husks and grains after separation cannot be collected better, affecting the experimental progress. Therefore, a grinding equipment for biological laboratories is needed to solve the above problems.

[0006] To achieve the above object, the technical solution adopted by the utility model is as follows: A grinding device for a biological laboratory, comprising a base, two first support legs, a second support leg, a grinding assembly, an extrusion assembly and a discharge port. The two first support legs and the second support leg are respectively fixedly arranged around the base, and a driving assembly is fixedly arranged on one side of the top of the second support leg. A grinding assembly is rotatably arranged on the tops of the two first support legs and the driving assembly. An extrusion assembly is fixedly arranged on one side of the grinding assembly. The extrusion assembly includes a lead screw fixing block and an extrusion motor fixing plate respectively fixedly arranged on one side of the grinding assembly. A lead screw is rotatably arranged in the lead screw fixing block. A first helical gear is fixedly arranged at the bottom of the lead screw. An extrusion motor is fixedly arranged on one side of the extrusion motor fixing plate, and a second helical gear is rotatably arranged on the other side. The second helical gear is fixedly connected to the output end of the extrusion motor. The first helical gear and the second helical gear are meshed and rotated. A lead screw sliding sleeve is rotatably arranged on the lead screw. A connecting cross bar is fixedly arranged on one side of the lead screw sliding sleeve. The other end of the connecting cross bar is movably connected to a connecting vertical bar. The bottom of the connecting vertical bar is fixedly connected to a grinding disc. A grinding groove is formed on the top of the base. A discharge port is fixedly arranged on one side of the base. A collection box is slidably arranged below the discharge port.

[0007] The extrusion assembly can adjust the position of the grinding disc up and down, so as to adjust the grinding disc to adapt to crop seeds of different specifications and sizes; the discharge port can discharge the husks and grains of the ground seeds; the collection box can collect the ground seeds.

[0008] Further, the driving assembly includes a driving motor fixing plate fixedly arranged on one side of the top of the second support leg. A driving motor is fixedly arranged at the bottom of the driving motor fixing plate. A first spur gear is rotatably arranged on the top of the driving motor fixing plate. The first spur gear is fixedly connected to the output end of the driving motor. A second spur gear is rotatably arranged on the top of the second support leg. The top of the second spur gear is fixedly connected to a connecting rod. The first spur gear and the second spur gear are meshed and rotated.

[0009] The driving assembly can provide power for the grinding assembly, so that the grinding assembly operates regularly to grind the seeds.

[0010] Further, the grinding assembly includes the first support legs, connecting rods and sleeve connecting rods. There are multiple sleeve connecting rods. The other ends of the connecting rods are respectively rotatably connected to one ends of the sleeve connecting rods. The other ends of the sleeve connecting rods are fixedly connected to the peripheries of the bottoms of the grinding sleeves. The grinding disc is slidably arranged in the grinding sleeve.

[0011] The grinding assembly can grind the material and separate the husk and grain of the material.

[0012] Further, a protective housing is arranged around the base.

[0013] The protective housing can protect the interior of the device and avoid the phenomenon that the staff is accidentally touched and injured when the device is running.

[0014] The working principle and usage principle of the present utility model are as follows: When using this device, the staff first place the seeds of the crops in the grinding grooves on the base. Then, the staff controls the extrusion motor through the controller to adjust the gap between the grinding disc to a size suitable for the seeds. After the adjustment is completed, the controller controls the driving motor to operate. The driving motor drives the first spur gear and the second spur gear to engage and rotate. The second spur gear drives the connecting rod at the top of the second spur gear to rotate axially. The connecting rod rotates axially between the two first support legs and the top of the second spur gear, and at the same time drives the sleeve connecting rod, the grinding sleeve and the extrusion assembly to rotate axially in the grinding grooves on the top of the base, so as to rotate and grind the seeds of the crops. During grinding, according to the rotational centrifugal force of the grinding disc, the seed husks and grains separated by grinding are discharged from the discharge port and flow into the collection box. After grinding is completed, the controller controls the driving motor to stop, takes out the collection box, and proceeds with subsequent work.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: This device can adjust the distance between the grinding disc and the seeds according to the size of the seeds of the crops, avoiding the damage to the seeds and grains during grinding caused by too low a gap between the grinding disc and the seeds, which affects the experimental results. After grinding and separation, the husks and grains are manually swept to the discharge port and fall into the collection box from the discharge port, which can better collect the husks and grains. Moreover, this device has the advantages of increasing the diversity of the types of seeds ground and high grinding efficiency. Description of the Drawings
