Description

Technical Field

[0001] The invention relates to the technical field of feed processing, in particular to a raw material crusher for mixed feed processing. Background Art

[0002] Feed processing is a complex process involving a variety of mechanical equipment and process flows, which aims to convert various raw materials into feed suitable for animal consumption. Among them, bone mud is a product made from animal bones through a special process. It contains protein, fat, vitamins, collagen, chondroitin and rich trace elements, especially high calcium content. In food processing, bone mud can be refined through different crushing principles to extract nutrients from the bones.

[0003] In the prior art, the comminution process of livestock and poultry bones can be roughly divided into the steps of pretreatment, crushing, coarse crushing, and fine crushing. Coarse crushing refers to the process of breaking the larger bone raw materials after pretreatment and crushing into smaller fragments through mechanical force, so as to facilitate the subsequent fine crushing of the bone raw materials. However, in the process of coarse crushing of livestock and poultry bones, the hardness of the bone raw materials will be different due to different parts or individuals, and the crushing gap of the conventional grinder is relatively fixed. When encountering too hard bone raw materials, they cannot be crushed and can only be removed by screening or manual removal, resulting in the equipment being unable to effectively utilize the bone raw materials.

[0020] 3.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 9 The present invention provides a technical solution: a raw material grinder for mixed feed processing, comprising a housing 1, a grinding chamber 28 is provided in the housing 1, a carrier plate 22 is provided in the grinding chamber 28, a grinding disc 21 is provided above the carrier plate 22, a grinding gap for grinding raw materials is reserved between the carrier plate 22 and the grinding disc 21, and the grinding gap gradually increases from the center to the outside, a drop pipe 24 is fixedly installed at the center of the carrier plate 22, a filter screen 23 is fixedly installed at the pipe mouth of the drop pipe 24, and a flow sensor is also provided in the drop pipe 24;

[0033] It also includes a lifting component, which is used to adjust the grinding gap between the carrier plate 22 and the grinding plate 21, and the lifting component is connected to the flow sensor by electrical signals.

[0034] When the device is used, the bone material is first placed on the carrier plate 22 in the grinding chamber 28, and then the grinding plate 21 and the carrier plate 22 are driven to rotate relative to each other by an external component. Figure 2 As shown, as the grinding gap gradually narrows, the raw material moves from the maximum point of the grinding gap to the center of the grinding gap, and after being squeezed at different levels, it is gradually crushed to be able to pass through the minimum point of the grinding gap and discharged from the shell 1 through the filter 23 from the drop pipe 24, completing the coarse grinding of the raw material, and the flow sensor detects the flow rate of the crushed raw material discharged through the filter 23. When the flow rate is within the set range, the grinding disc 21 and the supporting disc 22 rotate relative to each other. When the flow rate is lower than the set range, the external component stops driving the grinding disc 21 and the supporting disc 22 to rotate relative to each other, and drives the grinding gap between the grinding disc 21 and the supporting disc 22 to narrow through the lifting component. At this time, the raw material in the grinding gap that cannot be crushed due to its high hardness is further squeezed and crushed, completing the crushing of the high hardness raw material, and the crushed raw material is discharged through the drop pipe 24.

[0035] In this way, the discharge of the raw materials after crushing is monitored by the flow sensor, so that the raw materials that are easier to crush after pretreatment (such as freezing) are crushed first and discharged from the shell 1. When the flow sensor detects that the discharge rate of the raw materials is significantly reduced, the grinding gap between the grinding disc 21 and the supporting disc 22 is adjusted by the lifting assembly, and the hard raw materials that cannot be crushed in the original grinding gap are squeezed and crushed until the bone raw materials in the grinding chamber 28 are completely crushed and discharged from the shell 1, thereby enhancing the device's ability to handle bone raw materials of different hardness, avoiding the hardness of the raw materials that the device cannot crush, and making the device no longer need to screen or manually remove the hard bones, thereby improving the utilization rate of the raw materials and reducing the cost of use.

[0036] In this way, by adjusting the grinding gap, bone materials of different hardness can be crushed in batches, avoiding the grinding gap being too small in the initial state that makes it difficult for the bone material to pass through, and also avoiding the grinding disc 21 being subjected to excessive grinding shear force in the early stage of grinding, which helps to extend its service life.

[0037] Furthermore, the lifting assembly includes a sliding tube 13 fixedly installed at the center of the grinding disc 21, and a horizontal plate 17 is fixedly installed on the outer wall of the sliding tube 13. A driving chamber 8 is also opened in the housing 1, and a plurality of groups of cylinders 18 are fixedly installed on the inner bottom wall of the driving chamber 8. One end of the main shaft of the cylinder 18 penetrates into the grinding chamber 28 and is fixedly connected to the top surface of the horizontal plate 17:

[0038] The mixed feed processing raw material pulverizer further comprises a driving assembly, and the driving assembly is used to drive the sliding tube 13 to rotate.

[0039] According to the above embodiment, a specific embodiment of a lifting component is provided, in which the driving component drives the sliding tube 13 to rotate together with the grinding disc 21, so that the grinding disc 21 and the supporting disc 22 rotate relative to each other, and the raw materials falling into the largest grinding gap are squeezed and crushed, and discharged from the shell 1 through the drop pipe 24. When the flow sensor detects that the amount of raw materials passing through the drop pipe 24 is reduced to outside the preset range, the driving component stops, and then the cylinder 18 starts and drives the cross plate 17 to descend through the main shaft, driving the sliding tube 13 and the grinding disc 21 to descend together, so that the grinding gap between the grinding disc 21 and the supporting disc 22 is reduced, and the grinding force that increases with the reduction of the grinding gap is used to crush the hard bone raw materials, so that the hard raw materials that cannot be crushed in the original grinding gap are crushed, and the crushing of the hard raw materials is completed.

[0040] In this way, the driving assembly drives the sliding tube 13 to rotate together with the grinding disk 21, completing the relative rotation between the grinding disk 21 and the supporting disk 22, and the cylinder 18 pushes the cross plate 17 and the sliding tube 13 to descend together to reduce the grinding gap between the grinding disk 21 and the supporting disk 22, thereby completing the above-mentioned adjustment of the grinding gap.

[0041] Further, the driving assembly includes a first motor 3 fixedly mounted on the top surface of the housing 1, a portion of the main shaft of the first motor 3 that penetrates into the empty slot opened in the housing 1 is fixedly connected to a first driving gear 6, a first transmission gear 7 that meshes with the first driving gear 6 is rotatably mounted in the empty slot, a first bevel gear 9 is rotatably mounted on the top surface of the driving cavity 8, the first transmission gear 7 and the first bevel gear 9 are coaxially fixed to the outer wall of the rotating shaft 4, a second bevel gear 10 that meshes with the first bevel gear 9 is rotatably mounted on the side wall of the driving cavity 8, and the driving A third bevel gear 11 meshing with the second bevel gear 10 is rotatably installed on the bottom surface of the dynamic cavity 8, an upper rotating sleeve 15 is coaxially fixedly installed on the bottom end of the first bevel gear 9, and a lower rotating sleeve 16 is coaxially fixedly installed on the top end of the third bevel gear 11, and a fixed sleeve 12 fixed to the side wall of the driving cavity 8 is rotatably installed between the first bevel gear 9 and the third bevel gear 11, and a spline is provided at the end of the sliding tube 13 that penetrates into the driving cavity 8, and spline grooves for spline insertion or removal are provided at the bottom end of the upper rotating sleeve 15 and the top end of the lower rotating sleeve 16.

[0042] According to the above embodiment, a specific embodiment of a driving component is adopted. Figures 2 to 6 When the flow sensor detects that the amount of raw materials passing through the blanking tube 24 is within a preset range, the spline at the end of the sliding tube 13 is inserted into the upper rotating sleeve 15, that is, the sliding tube 13 is driven by the first motor 3 to rotate the first bevel gear 9 together with the upper rotating sleeve 15. Since the sliding tube 13 is released from the rotation lock with the lower rotating sleeve 16 when inserted into the upper rotating sleeve 15, the third bevel gear 11 is driven by the second bevel gear 10 to rotate in the opposite direction of the first bevel gear 9.

[0043] When the flow sensor detects that the amount of raw materials passing through the drop tube 24 is reduced to outside the preset range, the cylinder 18 starts and drives the cross plate 17 to descend through the main shaft, driving the sliding tube 13 and the grinding disc 21 to descend together. The sliding tube 13 descends and disengages from the upper rotating sleeve 15 and is inserted into the lower rotating sleeve 16, releasing the rotation lock with the upper rotating sleeve 15 and completing the rotation lock with the lower rotating sleeve 16, that is, the first motor 3 drives the first bevel gear 9 to rotate, and drives the third bevel gear 11 and the sliding tube 13 to rotate together through the second bevel gear 10, so that the rotation direction of the sliding tube 13 is opposite to that before the descent, driving the grinding disc 21 to rotate in the opposite direction, completing the adjustment of the grinding gap above and causing the grinding disc 21 to rotate in the opposite direction.

[0044] In this way, by adjusting the grinding gap and driving the grinding disc 21 to reverse at the same time, the grinding surface of the grinding disc 21 that is not under stress during coarse grinding can be used to grind the harder bone material, thereby avoiding wear of the conventional stress-bearing surface of the grinding disc 21 due to excessive use, and preventing the worn stress-bearing surface from being unable to grind the overly hard bone material, thereby ensuring that the bone material is fully crushed for subsequent fine grinding, and the two sides of the grinding disc 21 can also be set to materials of different hardness to grind bones of different hardness.

[0045] Furthermore, the outer wall of the sliding tube 13 is fixedly connected to a rotating sleeve 36, and a corrugated groove 38 is provided on the outer wall of the rotating sleeve 36. A pressing block 20 capable of sliding in the groove at the top of the grinding disc 21 is connected to the outer wall of the rotating sleeve 36. The pressing block 20 is fixedly installed on the top surface of the grinding chamber 28 through the telescopic rod 19 at the top, and a through hole is provided on the cross plate 17 for the telescopic rod 19 to pass through. A slider capable of sliding in the corrugated groove 38 is fixed on the inner wall of the pressing block 20, and a slider connected to the external liquid supply device is fixedly installed on the side wall of the grinding chamber 28. The liquid storage ring 29 is connected with the closed space formed by the top of the grinding disc 21 and the bottom of the pressing block 20 through a pipeline, and a one-way valve is installed in the pipeline. The sliding tube 13 and the rotating sleeve 36 are provided with a through hole connected with the closed space, and a one-way valve is installed in the through hole. A discharge pipe 35 is provided in the through hole. The top of the discharge pipe 35 passes through the sliding tube 13, the upper rotating sleeve 15 and the rotating shaft 4, and is rotatably connected with the external liquid outlet pipe 2. The upper rotating sleeve 15 and the rotating shaft 4 are provided with a channel for the discharge pipe to pass through.

[0046] According to the above embodiment, when the sliding tube 13 rotates, it drives the slider to slide in the corrugated groove 38, and drives the pressing block 20 to slide up and down in the groove at the top of the grinding disc 21. Figure 7 and Figure 8 When the pressing block 20 rises, the air pressure in the closed space formed by the bottom surface of the pressing block 20 and the top of the grinding disc 21 increases, and the coolant is sucked into the closed space from the liquid storage ring 29 to cool the grinding surface of the bottom end of the grinding disc 21 to avoid the grinding disc 21 generating heat due to friction with the raw material during the crushing process. Excessive heat will cause the raw material that has been cold-treated to heat up, and the ductility of the raw material will increase, thereby increasing the difficulty of crushing the raw material by the grinding disc 21. Then the pressing block 20 descends, and the coolant in the closed space is squeezed into the drain pipe 35 from the through hole located at the bottom center of the top of the grinding disc 21, and discharged from the shell 1 through the liquid outlet pipe 2, completing the cooling of the grinding disc 21 during the grinding process.

[0047] In this way, the pressing block 20 slides back and forth up and down in the groove at the top of the grinding disk 21, driving the coolant to continuously flow through the top surface of the grinding disk 21, and the grinding surface of the grinding disk 21 is cooled by the coolant, so that the grinding disk 21 always maintains a low temperature, avoiding the heat generated by friction from thawing the raw materials, improving the ductility of the raw materials and increasing the difficulty of crushing. At the same time, the low temperature is used to alleviate the metal fatigue caused by the grinding surface of the grinding disk 21 after long-term operation.

[0048] It is worth mentioning that in order to avoid thawing of the raw materials, a low-temperature environment needs to be maintained in the grinding chamber 28. Therefore, the shell 1 needs to be made of heat-insulating material, and the coolant will absorb the heat in the grinding chamber 28 through the liquid storage ring 29 and the pipeline during circulation cooling, so as to achieve the purpose of keeping the grinding chamber 28 at a lower temperature, thereby forming a low-temperature environment in the grinding gap.

[0049] Furthermore, a second motor 25 is fixedly mounted on the bottom surface of the shell 1, and a portion of the main shaft of the second motor 25 that penetrates into a cavity opened in the shell 1 is fixedly connected to a second driving gear 26, and a second transmission gear 27 that is fixed to the outer wall of the blanking tube 24 and meshes with the second driving gear 26 is provided in the cavity.

[0050] According to the above embodiment, when the second motor 25 drives the second driving gear 26 to drive the second transmission gear 27 to rotate together, it can drive the drop tube 24 and the carrier plate 22 to rotate together. If the grinding gap is reduced and still cannot meet the crushing requirements of the hard raw materials, the carrier plate 22 can be driven to rotate in the opposite direction of the grinding plate 21 to increase the friction force of the carrier plate 22 and the grinding plate 21 on the raw materials, so as to achieve the purpose of crushing the hard raw materials.

[0051] When the flow sensor detects that the amount of raw materials passing through the drop tube 24 is reduced to outside the preset range, the lifting assembly is driven to drive the grinding disc 21 to rise, and then the second motor 25 is used to drive the supporting disc 22 to rotate, so that the hard raw materials in the center of the grinding gap but unable to pass through the filter 23 can be sent to the periphery of the supporting disc 22 through centrifugal force, and then the grinding disc 21 is lowered and the grinding gap is narrowed to prevent the hard raw materials above the filter 23 from being squeezed by the grinding disc 21 after the grinding gap is narrowed, causing damage to the filter 23, and the grinding time of the raw materials moving from the maximum grinding gap to the minimum grinding gap is increased, which is more conducive to the crushing of the hard raw materials.

[0052] Furthermore, a fixing ring 32 that fits with the supporting plate 22 is fixedly installed on the bottom surface of the grinding chamber 28, a sliding ring 33 is slidably installed on the side wall of the grinding chamber 28, the outer wall of the sliding ring 33 is provided with a tooth groove, and an elastic strip 34 is fixedly installed between the sliding ring 33 and the fixing ring 32, a limiting ring 31 is slidably installed on the side wall of the grinding chamber 28, a limiting rod 30 that can slide in the annular groove opened in the limiting ring 31 is fixedly installed on the outer wall of the grinding plate 21, the bottom surface of the limiting ring 31 is fixedly connected to the rack 14, and a reversing gear 37 that meshes with the tooth groove and the rack 14 is rotatably installed on the side wall of the grinding chamber 28.

[0053] According to the above embodiment, when the driving lifting assembly drives the grinding disc 21 to rise, the limiting rod 30 and the limiting ring 31 rise together. Fig. 9 At this time, the limit ring 31 drives the rack 14 to descend to a horizontal state through the reversing gear 37, so that the raw materials thrown out by the centrifugal force of the rotation of the carrier plate 22 can fall on the elastic strip 34. When the driving lifting assembly drives the grinding plate 21 to descend, the limit rod 30 and the limit ring 31 descend together. At this time, the limit ring 31 drives the rack 14 to rise through the reversing gear 37, so that the rack 14 rises, drives the elastic strip 34 to tilt and sends the raw materials on the elastic strip 34 back to the carrier plate 22, so as to avoid the raw materials being thrown out when the carrier plate 22 rotates and unable to return to the carrier plate 22, which affects the crushing processing of the raw materials.

[0054] Furthermore, a grinding block is provided on the bottom surface of the grinding disc 21 , and two surfaces of the grinding block in the rotation direction of the grinding disc 21 are respectively a flat surface and a pointed surface.

[0055] According to the above embodiment, when the grinding disc 21 does not descend, the force-bearing surface of the grinding block on the raw material is a plane. When the grinding disc 21 descends and reduces the grinding gap, the force-bearing surface of the grinding block becomes a pointed surface when the grinding disc 21 reverses. The plane can increase the extrusion area of ​​the raw material. Therefore, it is suitable for raw materials that are easier to crush to improve their crushing efficiency. When the original extrusion force is not enough to crush hard raw materials, the force-bearing area of ​​the grinding block is switched to a pointed surface to enhance the crushing effect on the hard raw materials and improve the crushing efficiency of the hard raw materials.

[0056] Furthermore, a feed port 5 is provided on the outer wall of the shell 1 .

[0057] According to the above embodiment, it can be known that the feed port 5 is provided on the outer wall of the shell 1 so that the raw materials can enter the grinding chamber 28 more easily.

[0058] Furthermore, the top surface of the pressing block 20 is set to be a conical surface.

[0059] According to the above embodiment, when the raw material is raised through the feed port 5 and enters the grinding chamber 28, a portion of the raw material will fall on the top surface of the pressing block 20. Therefore, the top surface of the pressing block 20 is set to a conical surface to ensure that the raw material can pass through the gap between the pressing block 20 and the side wall of the grinding chamber 28 and fall into the supporting plate 22 to ensure that the device can crush the raw material normally.

[0060] Furthermore, the pipeline water inlet in the pressing block 20 is located at a position close to the bottom of the cone.

[0061] According to the above embodiment, the water inlet of the pipe in the pressing block 20 is set at a position close to the bottom of the cone, so that the coolant will flow from the bottom of the cone to the top of the cone after entering the closed space, so that the coolant can evenly cool every part of the grinding disk 21, avoiding the temperature of the local position of the grinding surface of the grinding disk 21 to rise and thaw the raw material at that position.

[0062] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
