[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0028] See also Figure 1 - Figure 8 , a multi-stage crushing barrel for veterinary drug processing, comprising a crushing barrel body 1 and two crushing rollers 2 installed on the inner side of the top of the crushing barrel body 1, a connected feeding hopper 3 is fixedly installed on the top of the crushing barrel body 1, the two crushing rollers 2 are connected to a U-shaped mounting frame 4 on the side away from each other, and the two ends of the two crushing rollers 2 are rotatably connected to the two ends of the two U-shaped mounting frames 4 through a rotating shaft, and U-shaped holes 101 are opened on both sides of the crushing barrel body 1, and the two U-shaped mounting frames 4 are respectively slidably connected to the two U-shaped holes 101, and the ends of the two U-shaped mounting frames 4 are respectively abutted against the side adjacent to the two U-shaped holes 101, and one side of the ends of the two U-shaped mounting frames 4 is fixedly connected with a crushing motor 5, and the output shafts of the two crushing motors 5 are respectively fixedly connected to the rotating shafts of the two crushing rollers 2, and the two U-shaped mounting frames 4 are connected to a yield assembly on the side away from each other, and a fixing assembly is connected between the two yield assemblies, and the fixing assembly is connected to the crushing barrel body 1.
[0029] like Figure 1 - Figure 8 As shown, the multi-stage crushing barrel for veterinary drug processing in the utility model is similar to the structure of the existing multi-stage crushing barrel for veterinary drug processing. The main improvement of the utility model is to improve the stability of the crushing operation of the crushing roller 2, such as Figures 1 to 8As shown, when the multi-stage crushing barrel for veterinary drug processing in the utility model is in use, raw materials are added to the crushing barrel body 1 through the feeding hopper 3, and the raw materials fall between the two crushing rollers 2. The crushing motor 5 drives the crushing rollers 2 to perform crushing operations. When there are harder objects that cannot be crushed by the two crushing rollers 2, the two crushing rollers 2 squeeze the harder objects. Through the yielding component, the two crushing rollers 2 and the U-shaped mounting frame 4 are moved away from each other, so that the harder objects fall from between the two crushing rollers 2 that yield to each other onto the screen inside the crushing barrel body 1, thereby avoiding rigid extrusion between the crushing rollers 2 and the hard objects, resulting in pits and damage when the crushing rollers 2 squeeze the hard objects, and improving the stability of the crushing rollers 2.
[0030] like Figure 1 - Figure 8 As shown, the fixed assembly includes two U-shaped frames 6 and two rectangular frames 7, the two rectangular frames 7 are respectively fixedly connected to the two sides of the crushing barrel body 1, the two crushing motors 5 are both located on the inner side of one of the rectangular frames 7, the two U-shaped frames 6 are respectively located at the two ends of the two rectangular frames 7, and the two ends of the U-shaped frames 6 are respectively fixedly connected to the ends of the two rectangular frames 7, and the two yielding assemblies are respectively located between the two U-shaped frames 6 and the two U-shaped mounting frames 4. Through the two U-shaped frames 6, the two U-shaped mounting frames 4 are respectively mounted on the two ends of the rectangular frame 7, and when the two U-shaped mounting frames 4 yield and move, the two crushing motors 5 can move with the U-shaped mounting frames 4 inside the rectangular frame 7.
[0031] like Figure 3 - Figure 5 As shown, the yielding assembly includes a plurality of yielding springs 8, and the plurality of yielding springs 8 are evenly distributed between the U-shaped frame 6 and the adjacent U-shaped mounting frame 4. When the two crushing rollers 2 contact a harder object, the hard object will squeeze and push the two crushing rollers 2 to both sides, and the yielding springs 8 will make a lateral movement to yield, and then the hard object will fall from the middle of the two crushing rollers 2 when the crushing rollers 2 rotate, and then the two crushing rollers 2 that yield to each other will return to their original positions under the action of the yielding springs 8 to continue the crushing operation.
[0032] like Figure 1 - Figure 5 As shown, a side of the U-shaped frame 6 close to the adjacent U-shaped mounting frame 4 is fixedly connected to a limiting block 9, a side of the U-shaped mounting frame 4 close to the adjacent U-shaped frame 6 is fixedly connected to a limiting frame 10, an outer wall of the limiting block 9 is slidably connected to an inner wall of the limiting frame 10, a yielding spring 8 is located in the limiting frame 10, and both ends of the yielding spring 8 are respectively fixedly connected to the limiting block 9 and the U-shaped mounting frame 4. When the crushing roller 2 yields and retracts, the limiting block 9 is slidably limited in the limiting frame 10, so that the yielding movement of the U-shaped mounting frame 4 inside the U-shaped frame 6 is more stable.
[0033] like Figure 1 - Figure 5As shown, both ends of the U-shaped mounting frame 4 located in one side of the limiting frame 10 are fixedly connected with anti-dropout rods 11, and a plurality of yield springs 8 are located between the two anti-dropout rods 11. The other ends of the two anti-dropout rods 11 successively penetrate the limiting block 9 and the U-shaped frame 6, and are fixedly connected with anti-dropout blocks 12, and the two anti-dropout blocks 12 are both against the side of the U-shaped frame 6 away from the U-shaped mounting frame 4. When the yield spring 8 drives the U-shaped mounting frame 4 to move to the middle position of the crushing barrel body 1, the anti-dropout rod 11 and the anti-dropout block 12 can prevent the U-shaped mounting frame 4 from moving too much toward the inside of the crushing barrel body 1, and can prevent the two crushing rollers 2 from colliding and contacting.
[0034] like Figure 6 As shown, a T-shaped slot 401 is provided on one side of the U-shaped mounting frame 4 close to the crushing roller 2, one end of the T-shaped slot 401 passes through the U-shaped mounting frame 4, a brush 13 is connected in the T-shaped slot 401, a brush plate of the brush 13 is slidably connected to the T-shaped slot 401, and the bristles of the brush 13 pass through the T-shaped slot 401 and abut against the adjacent crushing roller 2. Through the design of the T-shaped slot 401, the brush handle of the brush 13 can be inserted into the T-shaped slot 401, and when the crushing roller 2 rotates, the powder attached to the surface of the crushing roller 2 can be swept away by the brush 13.
[0035] like Figure 8 As shown, a shrink hole 402 is provided on the inner wall of a T-shaped slot 401 that passes through one end of the U-shaped mounting frame 4, and a plurality of reset springs 14 are fixedly connected in the shrink hole 402, and a block 15 is fixedly connected at the other end of the plurality of reset springs 14, and the block 15 is slidably connected to the shrink hole 402, and the block 15 abuts against the end of the brush plate of the brush 13, and the block 15 is away from one end of the reset spring 14, and a side away from the brush 13 is provided with an inclined surface. The end of the brush 13 is inserted inward from the opening end of the T-shaped slot 401, and is squeezed into the shrink hole 402 by being extruded with the inclined surface of the block 15. When the brush 13 completely enters the T-shaped slot 401, the reset spring 14 drives the block 15 to pop out of the shrink hole 402, and then abuts against the other end of the brush 13, so that the brush 13 can be fixed in the T-shaped slot 401, and the surface of the crushing roller 2 can be cleaned.
[0036] like Figure 6 and Figure 7As shown, a pop-up hole 403 is provided at one end of the T-slot 401 away from the shrink hole 402, and a plurality of pop-up springs 16 are fixedly connected in the pop-up hole 403. A pop-up block 17 is fixedly connected at the other end of the plurality of pop-up springs 16. The other end of the pop-up block 17 abuts against the end of the brush plate of the brush 13, and the pop-up block 17 is slidably connected to the pop-up hole 403. When the brush 13 needs to be taken out of the T-slot 401, the clamping block 15 is first pressed into the shrink hole 402. When the clamping block 15 completely enters the shrink hole 402, the pop-up spring 16 drives the pop-up block 17 to push the end of the brush handle of the brush 13 out of the T-slot 401 to pop out, so that the brush 13 can be more conveniently taken out of the T-slot 401, and the brush 13 can be conveniently replaced and installed.
[0037] like Figure 8 As shown, both sides of the clamping block 15 near one end of the return spring 14 are fixedly connected with sliders 18, and both sides of the shrinking hole 402 are provided with slide grooves 404, and the two sliders 18 are respectively slidably connected with the two slide grooves 404. When the return spring 14 drives the clamping block 15 to move outward, the sliders 18 slide in the slide grooves 404, so that the return spring 14 can prevent the entire clamping block 15 from being pushed out of the shrinking hole 402, and prevent the clamping block 15 from falling out of the shrinking hole 402.
[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
