Description

Technical Field

[0001] The utility model mainly relates to the technical field of meat food processing machinery, in particular to a novel multifunctional bone crusher. Background Art

[0002] At present, the residual meat and bone marrow produced by slaughtering cattle and sheep at home and abroad account for 30%-35%. In order to recycle these high-quality food resources, we can use our patented (publication number CN204157557U and CN204157557U) two kinds of bone and meat separators for recycling. However, because these bones are too hard, they must be crushed with a suitable bone crushing equipment first, and then the meat and bone residues are separated by the bone and meat separator. In addition, these two kinds of bone and meat separators can only process small fish and fish bone chops. Similarly, large fish bone chops also need to be crushed first because of their large and hard bones. At present, all bone crushing equipment on the market has two main problems: one is that the crushed particle size is large, which makes the bone and meat separator blocked and unable to produce normally; the other is that once crushed, the mixture of meat and bone residue is viscous, which makes the crusher blocked and unable to make the production line continuous production. Utility Model Content

[0003] In view of the deficiencies and defects in the prior art, the utility model provides a novel multifunctional bone crusher, which processes the bone according to a particle size suitable for a bone and meat separator and applies extrusion force to forcefully discharge the crushed mixture.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: a new multifunctional bone and meat crusher, characterized in that it includes two sets of roller roller crushing parts, a toothed roller crushing part, a reamer crushing part, a transmission part, a hopper, left and right machine walls, a frame and a reducer; the roller roller crushing part includes a sprocket, an outer spherical bearing with a seat, a pair of roller rollers, and a pair of gears; the toothed roller crushing part is mainly composed of a sprocket, a number of eagle-beak toothed cutter discs, a spacer, a pair of cutter disc shafts, a round nut, a bone crushing comb, an O-ring, a gear, etc.; the reamer crushing part is mainly composed of a sprocket, an outer spherical bearing, a pressure bearing, a spiral shaft, a meat grate, a reamer, a hole plate, etc.; the frame transmission part is composed of a hopper, left and right machine walls, a sprocket, a chain, a frame, an electrical cabinet, a reducer, etc.

[0005] The two sets of roller crushing parts, the first set of roller crushing parts is parallel to the roller rollers and placed below the hopper, with a larger gap in the middle, which can squeeze beef stocks and large pieces of sheep bones into fragments first; one end of a sprocket wheel made into a toothed shape of the roller roller is driven by a sprocket, and the other end is driven by a pair of gears to make the two rollers rotate towards each other, thereby implementing the first crushing of the bones; the second set of roller crushing parts is placed below the first set of roller crushing parts, and the gap between the rollers becomes smaller, so that the bone fragments crushed in the first crushing are further crushed.

[0006] The two pairs of roller crushing parts are each equipped with tooth tips and tooth grooves to break and crush the bones.

[0007] The toothed roller crushing part is placed at the lower part of the second pair of roller crushing part, and each cutter shaft is equipped with a number of eagle-beak toothed cutter discs, and spacers are installed between the eagle-beak toothed cutter discs. One end of the cutter shaft is provided with a positioning boss, and the other end is tightened with a round nut to form a toothed roller component. One end of the cutter shaft is driven by a sprocket, and the other end is equipped with a pair of gears to make the two groups of toothed rollers rotate relative to each other. The eagle-beak toothed cutter discs of the two toothed rollers are cross-installed, and the tooth tips of the eagle-beak toothed cutter disc installed on one roller are aligned with the recessed part of the eagle-beak toothed cutter disc installed on the other roller, and the gap between the tooth tips and the recessed part is 0.5-1mm, and the side gap is 1mm, so that the bone fragments are further crushed into small particles and small thin strips.

[0008] The size of the toothed rolling eagle-beak toothed cutter disc is determined according to the size of the processed bone, and the number of the eagle-beak-shaped cutter discs is determined by the production output of the bone crusher.

[0009] The reamer crushing part is placed at the lower part of the toothed roller crushing part, with a sprocket at one end, positioned by an outer spherical bearing and equipped with a pressure bearing. The left machine wall bears the spiral reverse thrust during operation, and the other end is equipped with a meat grate, a reamer and a hole plate in sequence.

[0010] The pitch of the screw shaft of the reamer crushing part is steplessly variable, and the pitch gradually decreases from feeding to discharging, so as to increase the pressure of the mixed material outlet.

[0011] The frame transmission part includes a hopper, left and right machine walls, a sprocket, a chain, a frame, an electrical cabinet, and a reducer;

[0012] The reducer is divided into two transmission paths through the sprocket. One path is driven by a double chain through the triple sprocket installed on the reducer to drive the quadruple sprocket at the left end of the toothed roller to rotate, and the other end of a pair of toothed rollers drives the other toothed roller to rotate through a pair of gears; the other two teeth of the quadruple sprocket drive the second roller to rotate relatively at the same speed through a double chain; one of the roller sprockets of the pair of rollers makes the roller rotate, and a pair of gears is installed at the right end of the second pair of rollers, so that the other left toothed roller drives the gear installed on the right toothed roller through the gear installed on its right, so that the pair of toothed rollers rotate relatively; the second pair of rollers rotates through the outer two teeth of the quadruple sprocket installed on the left end of one roller roller with a double chain through one roller roller installed on the first pair of rollers, and drives the first pair of rollers to rotate relatively through a pair of gears installed on the right end of the roller roller; as shown in the attached figure Figure 1 The sprockets in the right view are installed on the left end of the first pair of rollers, the second pair of rollers and the toothed roller; the other way is to directly drive the spiral shaft of the reamer crushing part to rotate through the single chain of the reducer sprocket to complete the four-stage crushing.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by utilizing the different crushing functions produced by four components with different structures, cattle bones or sheep bones are crushed through five stages, so that the particle size of the bone residue can meet the requirements, and the pitch of the spiral conveying material gradually becomes smaller, so that the material is subjected to increasingly greater extrusion pressure, and the mixture is squeezed out from several small holes of the perforated plate, so that the production line can operate normally.

DETAILED DESCRIPTION

[0028] In order to make the technical solution and beneficial effects of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementation methods described herein are only used to understand the utility model and are not used to limit the utility model. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the utility model.

[0029] Refer to the attached Figure 1 The utility model is composed of a roller crushing part 1, a toothed roller crushing part 2, a reamer crushing part 3, a transmission part 4, a hopper 5, left and right machine walls 6, a frame 7, and a reducer 8; the roller crushing part 1, the toothed roller crushing part 2, the reamer crushing part 3, the transmission part 4, and the hopper 5 are fixed on the left and right machine walls with a square seat outer spherical bearing, and the hopper 5 is fixed on the uppermost part of the left and right machine walls. Bones first fall from the hopper into the upper roller crushing part 1, such as Figure 3 As shown, the tooth tips of the two rollers are opposite to each other at the horizontal line, and the bones are crushed and broken by the rollers to complete the first crushing; the bone pieces crushed by the first roller are relatively large, and the bone pieces and bone particles become smaller after the second crushing, and the broken bones in the second crushing fall into the toothed roller crushing part 2. It should be noted that the diameter of the roller and the size of the tooth shape are determined by the size of the bone. The diameter of the cattle bone should be large, and the gap between the tooth tip and the tooth should also be increased. The gap between the tooth tip and the tooth is required to be greater than the wall thickness of the bone.

[0030] like Figure 4 As shown, the toothed crushing part 2 is composed of a plurality of eagle-shaped toothed cutter discs 16 fixed to the left toothed roller 21 and the right toothed roller 15 by round nuts 21, and the left and right toothed rollers eagle-shaped teeth are cross-assembled, and the left and right eagle-shaped teeth have a gap of 0.5-1mm, and are further crushed and sheared by the eagle-shaped toothed cutter disc 16. Figure 5The shadows in the upper and lower parts show that the two toothed rollers rotate in opposite directions, and the materials entering the two toothed rollers are crushed as the cavity gradually decreases, and the third crushing of the bone is completed in the toothed crushing part 2. It should be noted that the diameter and the size of the eagle beak tooth shape of the cutter disc 16 are determined by the diameter of the bone. The eagle beak tooth shape of the cattle bone should be large, and the diameter of the corresponding eagle beak tooth cutter disc 16 should also be increased; and the number of eagle beak tooth cutter discs is determined by the required output. If the required output is high, the number of eagle beak tooth cutter discs needs to be large.

[0031] Refer to the attached Figure 8 The reamer crushing part of the utility model mainly consists of a spiral sprocket 22, a square seat outer spherical bearing 23, a pressure bearing 24, a spiral shaft 27, a lower hopper 28, a feeding pipe 29, a meat grate 30, a reamer 31, a hole plate 32, etc. The mixture of meat and bone residues after the second crushing falls into the feeding pipe 29 through the hopper 28 and is pushed forward by the rotating spiral shaft 27. As the advancing pitch of the spiral shaft gradually decreases, the mixture of meat and bone residues is subjected to an increasingly greater extrusion force. The bone residues are sheared by the meat grate 30 and the reamer 31 and are crushed for the third time. The meat paste and bone residues with smaller particle sizes are squeezed out from several small holes of the hole plate 32, and the larger bone residues that cannot be discharged from the small holes of the hole plate 32 are repeatedly crushed by the reamer 31 and the hole plate 32 for the fourth time until the particle size of the bone residues is small enough to be discharged from the small holes of the hole plate 32; the reamer is made into a double-edged blade.

[0032] Reference Figure 1 , Figure 4 and Figure 8 The reducer 8 is installed in the frame 7, and is divided into two paths through the triple sprocket installed on the output shaft of the reducer 8 through the chain. One path uses a double chain through the quadruple sprocket 14 and the double chain to drive the left toothed roller to rotate, and the gear installed at the other end of the left toothed roller drives the right toothed roller gear to make the two toothed rollers rotate towards each other; in addition, the other two rows of teeth in the quadruple sprocket installed on the left toothed roller drive the left roller roller to rotate with a chain, and the gear installed at the other end of the left roller roller drives the gear of the right roller roller, so that the two roller rollers rotate towards each other with the tooth tips facing the teeth concave at the horizontal line; the other row of teeth of the triple sprocket installed on the output shaft of the reducer 8 drives the spiral shaft 27 to rotate with a chain through the sprocket 22 installed on the spiral shaft.
