[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-4 As shown, a meat scrap crushing and screening device includes a support mechanism 1 for supporting the entire device, and a crank-connecting rod mechanism 3 is provided on the support mechanism 1.

[0025] In this embodiment: the support mechanism 1 includes a base frame 11, a base 12 is fixedly installed at the lower end of the base frame 11, a drive assembly is provided on the base frame 11, multiple support plates 13 are fixedly installed on the base frame 11, a housing 14 is fixedly installed on the support plates 13, a crushing assembly is fixedly installed at the upper end of the housing 14, the drive assembly includes a motor 21 fixedly installed on the base frame 11, a sprocket 23 is correspondingly installed at one end of the crankshaft 31, the rotating shaft of the motor 21 is fixedly connected to the sprocket 23, and a transmission chain 22 is installed between the sprockets 23, the crushing assembly includes a crusher 41 fixedly installed at the upper end of the housing 14. This crusher 41 is a conventional technology and will not be described in detail here. The top of the crusher 41 is provided with a feed inlet 42. When using the device, the meat scraps to be crushed are poured into the feed inlet 42, and the crusher 41 crushes the meat scraps. After crushing, the meat scraps fall onto the filter plate 51. At this time, the motor 21 is started, and the motor 21 drives the sprockets 23 to rotate. The power is transmitted between the sprockets 23 through the transmission chain 22.

[0026] In this embodiment: the crank-connecting rod mechanism 3 includes two crankshafts 31 rotatably mounted on the support plate 13. Multiple sets of first cranks 32 and second cranks 33 are provided on the crankshafts 31. A crank bushing 34 is mounted on the fixed shaft of the first crank 32. Multiple bushing pins 35 are fixedly mounted on the crank bushing 34. A connecting rod 36 is provided on the crank bushing 34. A connecting rod shaft is rotatably mounted on the other end of the connecting rod 36. Fixed plates 37 are fixedly mounted on both ends of the connecting rod shaft. A screening assembly is mounted on the fixed plate 37. The second crank 33 has the same structure as the first crank 32. The screening assembly includes a support plate 52 fixedly mounted on the fixed plate 37 to prevent meat scraps from falling. A fixed plate 52 is fixedly mounted on the support plate 37. A filter plate 51 is fixedly installed, and the filter plate 51 is provided with a grinding tooth for secondary crushing of meat scraps. The filter plates 51 are tightly fitted together and are slidably fitted with the housing 14. The first crank 32 and the crankshaft sleeve 34 are rotatably installed, and the fixed shafts of the first crank 32 and the second crank 33 are installed in opposite directions. When the crankshaft 31 rotates, the connecting rod 36 on the first crank 32 drives the filter plate 51 to move up and down, thereby sieving the meat scraps. When the filter plate 51 connected to the first crank 32 is at the upper stop, the filter plate 51 connected to the second crank 33 is at the lower stop. As the crankshaft 31 rotates, the filter plates 51 move up and down alternately to screen the meat scraps.

[0027] The working principle and usage process of this utility model are as follows: When using the device, the meat scraps to be crushed are poured into the feed inlet 42, and the meat scraps are crushed by the crusher 41. After crushing, the meat scraps fall onto the filter plate 51. At this time, the motor 21 is started, and the motor 21 drives the sprocket 23 to rotate. The sprocket 23 transmits power through the transmission chain 22, thereby driving the crank shaft 31 to rotate. When rotating, the connecting rod 36 on the first crank 32 drives the filter plate 51 to move up and down, thereby sieving the meat scraps. When the filter plate 51 connected to the first crank 32 is at the upper stop, the filter plate 51 connected to the second crank 33 is at the lower stop. As the crank shaft 31 rotates, the filter plates 51 move up and down alternately to screen the meat scraps.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
