Description

Technical Field

[0001] The present invention relates to the technical field of grinder equipment, in particular to an animal tissue sample grinder. Background Art

[0002] Oral scab is a viral, contagious disease common in sheep and goats, characterized by the formation of papules, blisters, pustules, and warty scabs on the lips, tongue, nose, and udders. In scientific research and production, the oral scab virus is typically isolated and cultured. Scabs, blister fluid, or proliferative tissue from infected sheep are collected and ground to a specified particle size, either manually or using a grinding device, for subsequent virus isolation.

[0003] With the advancement of industrialization, mechanization is gradually replacing traditional manual labor. Existing equipment, such as the ST-M50 high-throughput tissue grinder, utilizes a vertical up-and-down vibration mode. Through the high-frequency reciprocating vibration and impact of the grinding balls, sample preparation is rapidly achieved. This results in more complete and uniform grinding of samples, improved sample reproducibility, and no cross-contamination between samples.

[0004] However, the above-mentioned device only uses a vertical reciprocating vibration mode and grinding balls to quickly grind the material in the grinding bottle, which may result in incomplete grinding. In order to further improve the grinding effect of the equipment, an animal tissue sample grinder is proposed that can use an "∞"-shaped rotation trajectory and a vertical vibration mode to perform grinding operations to better meet the user's needs. Summary of the Invention

[0005] In order to solve the technical problem that the grinding equipment proposed in the background art has a single grinding method and may not be comprehensive during grinding, the present invention provides an animal tissue sample grinder.

[0006] The present invention is implemented by the following technical solution: an animal tissue sample grinder, comprising:

[0007] An outer shell, a protective cover hingedly connected to the top of the outer shell, a locking device provided at the connection between the protective cover and the other side of the outer shell, a control module provided on one side of the outer shell, and the control module electrically connected to the interior;

[0008] Also includes:

[0009] A guide ring body, the guide ring body slides vertically on the upper part of the inner wall of the outer shell, and the inner wall of the guide ring body is provided with a band groove 1 that fluctuates up and down periodically;

[0010] The placement mechanism is movable within the guide ring body and includes a circular frame, with round rods symmetrically fixedly connected to both sides of the bottom end of the circular frame, and a vertical plate fixedly connected to the middle of the bottom end of the circular frame, and a rotating rod fixedly connected to the middle of the vertical plate. The rotating rod and the round rod are coaxially arranged, wherein the round rod slides in the band slot one;

[0011] The guiding mechanism includes an inner guiding ring body, the inner guiding ring body is installed at the bottom end of the circular frame body, and the inner and outer walls of the inner guiding ring body are provided with a band groove 2, a sliding block is slidably connected in the band groove 2, the bottom end of the sliding block is fixedly connected to a vertical rod, the vertical rod is connected to a circular plate for relative horizontal sliding, the middle part of the circular plate is movably connected to a rotating sleeve block, the top of the rotating sleeve block is fixedly connected to a fixed sleeve block, and the fixed sleeve block is hinged to the rotating rod;

[0012] The vibration mechanism is arranged in the outer shell and is connected to the guide mechanism.

[0013] The above technical solution allows the protective cover to protect the interior and provide sound insulation when in place. Furthermore, the placement mechanism secures the grinding bottle. Because the device utilizes a guide mechanism for positional guidance, the placement balance of the grinding bottle can be ensured even when grinding is not in progress. Because the device utilizes a guide mechanism to perform a nearly "∞"-shaped cyclic rotation of the placement mechanism, and because the bottom vibration mechanism can also vibrate vertically, the grinding beads in the grinding bottle can be moved and impacted in multiple directions, accelerating grinding. The placement rack in the placement mechanism matches the cover and can be quickly assembled and disassembled to meet different usage requirements.

[0014] As a further improvement of the above scheme, the placement mechanism also includes a protrusion installed at the upper end of the middle part of the circular frame, a threaded hole is opened in the middle part of the protrusion, and a plurality of protrusions are evenly fixedly connected to the top of the protrusion. A cover plate is inserted above the circular frame, and slots are provided at the corresponding protrusions in the middle part of the cover plate. A clamping plate is abutted against the top end of the cover plate, and a screw is fixed in the middle part of the bottom end of the clamping plate, and the screw is threadedly connected to the threaded hole.

[0015] Through the above technical solution, the corresponding matching protrusions and the cover plate are plugged into each other for quick positioning and installation, and the threaded connection between the screw and the threaded hole can be used for further limiting and fixing to avoid rotation and falling off.

[0016] As a further improvement of the above scheme, a placement rack is installed in the middle of the circular frame, and multiple placement slots are opened in the middle of the placement rack and the cover plate, and the placement rack and the cover plate are both plug-in installed, and the placement slots are all inclined. Grinding bottles are placed in the placement slots, and grinding balls are placed in the grinding bottles.

[0017] Through the above technical solution, the placement groove in the inclined state can make the grinding balls collide better and irregularly as it rotates in the shape of "∞", thereby reducing the existence of dead corners inside the grinding bottle.

[0018] As a further improvement of the above scheme, the guiding mechanism also includes L-plates, which are symmetrically fixed on both sides of the circular plate, and the top ends of the two groups of L-plates are fixedly connected to the bottom end of the guide ring body. A horizontal groove is provided at the connection between the circular plate and the L-plate on one side, and the horizontal groove is slidably connected to the bottom end of the vertical rod.

[0019] Through the above technical solution, a sliding block that is slidably connected to the band slot 2 is used, and its vertical height is fixed relatively to the circular plate, so that in conjunction with the band-type band slot 2, the entire placement mechanism can be pulled to perform corresponding position changes in a hinged state. Moreover, since the inner guide ring body is fixed to the bottom end of the circular frame body, when it rotates around the rotating rod as the center, it will cause the inner guide ring body to shift, thereby utilizing the sliding of the horizontal slot and the vertical rod to perform adaptive changes.

[0020] As a further improvement of the above scheme, a slot is provided at the lower part of the outer wall of the rotating sleeve block, a ring block is slidably connected to the outer wall of the slot, the ring block is fixedly connected to the inner wall of the circular plate, the inner wall of the rotating sleeve block is symmetrically fixedly connected to the inner protrusion, and the inner protrusion is vertically slidably connected to the rotating shaft.

[0021] As a further improvement of the above solution, a motor is fixedly connected to the other end of the rotating shaft, the motor is installed at the bottom end of the inner wall of the outer shell, and is electrically connected to the control module. Vertical grooves are symmetrically opened on both sides of the outer wall of the rotating shaft, and the vertical grooves are vertically slidably connected to the inner protrusions.

[0022] Through the above technical solution, the vertical sliding of the vertical groove and the inner protrusion can drive the rotating sleeve to rotate, and simultaneously drive the top placement mechanism to slide along the sliding guide of the round rod and the band groove one. And because it is a wave setting, it will also undergo vertical displacement changes during rotation, and perform a combined movement of the two.

[0023] As a further improvement of the above scheme, the vibration mechanism includes a bottom protrusion fixedly installed on the bottom end of the circular plate, and the two groups of bottom protrusions are staggered and inclined. The outer side of the circular plate is symmetrically fixedly connected with a side plate, and the side plate is perpendicular to the L plate.

[0024] As a further improvement of the above solution, the inclined parts of the bottom protrusions are intermittently slidably abutted against top protrusions, the top protrusions are in two groups, and the bottom ends are fixedly connected to round blocks, and the round blocks are fixedly connected to the rotating shaft.

[0025] As a further improvement of the above solution, the top ends of the two groups of top protrusions are provided with rounded corners on the front side in the rotation direction, so as to push the circular plate to move in the vertical direction.

[0026] Through the above technical solution, the circular block is driven to rotate by rotating the rotating shaft, and the top protrusion and the bottom protrusion that are slidably connected can be used to intermittently push the circular plate to move vertically upward. By using the fixed connection between the L plate and the guide ring body, the entire placement mechanism can be synchronously driven to move vertically, providing vertical force during grinding.

[0027] As a further improvement of the above scheme, the bottom ends of the side plates are fixedly connected to dampers, and the bottom ends of the dampers are fixedly connected to the bottom ends of the inner walls of the outer shell to support the guide ring body. A spring is elastically connected between the inner wall of the outer shell and the side plates, and the spring is sleeved on the outside of the damper to drive the guide ring body back into position.

[0028] Through the above technical solution, the damper is used to support the entire circular plate, and can provide telescopic adaptability during vertical movement, and can rebound and contract under the action of the spring.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] The present invention utilizes a placement mechanism to quickly position and install the grinding bottle, and can also quickly disassemble and install a placement rack of a required size to meet the needs of different grinding specifications; the guiding mechanism enables the placement mechanism to rotate in a nearly "∞" shape under the drive of a motor, providing a complex force for the grinding balls in the tilted grinding bottle, and the grinding balls can cover the area inside the grinding bottle when colliding with each other, thereby improving the grinding efficiency.

[0031] The present invention utilizes a vibration mechanism that can cooperate synchronously with a guide mechanism to intermittently push the entire grinding mechanism to perform vertical reciprocating displacement, thereby providing vertical force for the grinding balls in the grinding bottle.

[0032] The present invention utilizes a sliding block that can slide horizontally along the horizontal groove, which can slide adaptively under the sliding connection with the band groove 2 to meet the needs of the placement mechanism when performing an "∞"-shaped rotation, ensuring stable guidance of the placement mechanism and maintaining the stability of the equipment during grinding.

[0060] A slot 19 is provided at the lower portion of the outer wall of the rotating sleeve 17 , a ring block is slidably connected to the outer wall of the slot 19 , and the ring block is fixedly connected to the inner wall of the circular plate 20 ; an inner protrusion 18 is symmetrically fixedly connected to the inner wall of the rotating sleeve 17 , and the inner protrusion 18 is vertically slidably connected to the rotating shaft 27 .

[0061] The other end of the rotating shaft 27 is fixedly connected to the motor 30, which is installed at the bottom end of the inner wall of the outer shell 1 and is electrically connected to the control module. Vertical grooves are symmetrically opened on both sides of the outer wall of the rotating shaft 27, and the vertical grooves are vertically slidably connected to the inner protrusion 18.

[0062] The vibration mechanism includes a bottom protrusion 26 fixedly mounted on the bottom end of the circular plate 20, and the two sets of bottom protrusions 26 are staggered.
