Description

Technical Field

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

[0002] Oral ulcer is a contact infectious disease caused by a virus that exists in sheep and goat groups. It is characterized by the formation of papules, blisters, pustules and warty scabs on the lips, tongue, nose, breasts, etc. In the process of scientific research and production, it is usually necessary to isolate and culture the oral ulcer virus, collect the scabs, blister fluid or hyperplastic tissue of the diseased sheep, grind them to a specified particle size manually or by a grinding device for subsequent virus isolation.

[0003] With the improvement of industrialization, mechanization has gradually replaced traditional manual labor. Existing equipment, such as the ST-M50 high-throughput tissue grinder, uses a vertical up-and-down vibration mode to quickly achieve the purpose of sample preparation through high-frequency reciprocating vibration and impact of the grinding balls. The ground samples are more complete, more uniform, and have better sample repeatability, and there is no cross-contamination between samples.

[0004] However, the above-mentioned device only uses a vertical reciprocating vibration mode and a grinding ball 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, so as to better meet the user's needs. Summary of the invention

[0005] In order to solve the technical problem that the grinding device proposed in the background technology 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: An outer shell, a protective cover is hingedly connected to the top of the outer shell, a locking device is provided at the connection between the protective cover and the other side of the outer shell, a control module is provided on one side of the outer shell, and the control module is electrically connected to the interior; Also includes: A guide ring body, the guide ring body vertically slides 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 which fluctuates up and down periodically; A placement mechanism, the placement mechanism moves in the guide ring body, including a circular frame, the bottom of the circular frame is symmetrically fixedly connected to round rods on both sides, and the middle of the bottom of the circular frame is fixedly connected to a vertical plate, the middle of the vertical plate is fixedly connected to a rotating rod, the rotating rod and the round rod are coaxially arranged, wherein the round rod slides in the band slot one; The guiding mechanism comprises 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 second band groove, a sliding block is slidably connected in the second band groove, a vertical rod is fixedly connected to the bottom end of the sliding block, a circular plate is slidably connected to the vertical rod relative to the horizontal, a rotating sleeve block is movably connected to the middle part of the circular plate, a fixed sleeve block is fixedly connected to the top end of the rotating sleeve block, and the fixed sleeve block is hinged to the rotating rod; The vibration mechanism is arranged in the outer shell and connected with the guide mechanism.

[0007] Through the above technical solution, the protective cover can be used to protect the interior, and it can play a role of sound insulation when the protective cover is on. Secondly, the placement mechanism can be used to fix the grinding bottle. Since the equipment uses the guide mechanism for limited guidance, the placement balance of the grinding bottle can be ensured when the grinding operation is not performed; since the equipment can perform a nearly "∞"-shaped circular rotation of the placement mechanism through the guide mechanism, and can also vibrate vertically under the action of the bottom vibration mechanism, the grinding beads in the grinding bottle can be moved and collided in more directions to accelerate the grinding. The placement frame in the placement mechanism matches the cover plate and can be quickly disassembled and assembled to meet different usage requirements.

[0008] 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 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.

[0009] Through the above technical solution, the corresponding matching protrusions and the cover plate are plugged in and connected to each other, so that the positioning and installation can be quickly carried out, and the threaded connection between the screw rod and the threaded hole can be used for further limiting and fixing to avoid rotation and falling off.

[0010] As a further improvement of the above scheme, a placing rack is installed in the middle of the circular frame, and a plurality of placing grooves are provided in the middle of the placing rack and the cover plate, and the placing rack and the cover plate are both inserted and installed, and the placing grooves are all inclined, and grinding bottles are placed in the placing grooves, and grinding balls are placed in the grinding bottles.

[0011] Through the above technical solution, the placement groove in the inclined state can make the grinding balls collide better and irregularly when rotating in the shape of "∞", thereby reducing the existence of dead corners inside the grinding bottle.

[0012] 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.

[0013] Through the above technical scheme, a sliding block is used which is slidably connected to the band slot 2, and its vertical height is relatively fixed with the circular plate, so as to cooperate with the band-type band slot 2, so that the entire placement mechanism can be pulled to make corresponding position changes in a hinged state, and because the inner guide ring body is fixed to the bottom end of the circular frame, when it rotates around the rotating rod, it will cause the inner guide ring body to shift, thereby making adaptive changes by utilizing the sliding of the horizontal slot and the vertical rod.

[0014] As a further improvement of the above scheme, a groove is opened at the lower part of the outer wall of the rotating sleeve block, and a ring block is slidably connected to the outer wall of the groove. The ring block is fixedly connected to the inner wall of the circular plate, and the inner wall of the rotating sleeve block is symmetrically fixedly connected with an inner protrusion, and the inner protrusion is vertically slidably connected to the rotating shaft.

[0015] As a further improvement of the above scheme, 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.

[0016] Through the above technical scheme, the rotating sleeve can be driven to rotate by utilizing the vertical sliding of the vertical groove and the inner protrusion, and the placement mechanism at the top can be simultaneously driven to slide along the sliding guide of the round rod and the band groove one. Moreover, due to the wave setting, vertical displacement changes will also occur during rotation, and the combined movement of the two will be performed.

[0017] As a further improvement of the above scheme, the vibration mechanism includes a bottom protrusion fixedly mounted on the bottom end of the circular plate, and the two groups of bottom protrusions are staggered and inclined, and 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.

[0018] 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 with round blocks, and the round blocks are fixedly connected to the rotating shaft.

[0019] 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.

[0020] Through the above technical scheme, the rotating shaft is used to drive the circular block to rotate, 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, and 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, thereby providing vertical force during grinding.

[0021] 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 for supporting 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 for driving the guide ring body back into place.

[0022] 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 shrink under the action of the spring.

[0023] Compared with the prior art, the present invention has the following beneficial effects: The present invention can use the 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 is used to realize a nearly "∞"-shaped rotation trajectory of the placement mechanism under the drive of a motor, so that a complex force is provided 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.

[0024] The present invention utilizes a vibration mechanism to cooperate synchronously with a guide mechanism to intermittently push the entire grinding mechanism to perform vertical reciprocating displacement, thereby providing a vertical force for the grinding balls in the grinding bottle.

[0025] The present invention utilizes a sliding block that can slide horizontally along a horizontal groove, and can slide adaptively under the sliding connection with the second band groove to meet the needs of the placement mechanism to rotate in an "∞" shape, thereby ensuring stable guidance of the placement mechanism and maintaining the stability of the equipment during grinding.
