Description

Technical Field

[0001] The invention belongs to the technical field of agriculture and animal husbandry, and in particular relates to a high-efficiency animal bone crusher. Background Art

[0002] A slaughterhouse is a place dedicated to slaughtering livestock and carrying out related processing. After processing the livestock in the slaughterhouse, there are often a lot of bones left that cannot be processed. These bones are hard and rich in nutrients. If they are discarded directly, it will cause a waste of nutrients, which is not in line with the development concept of green production in the slaughterhouse.

[0003] For this reason, bone crushers have appeared on the market for crushing livestock bones. The crushed livestock bones can be used to make soup first, and the used bones can be used as livestock feed to feed livestock, thereby improving the utilization rate of livestock bones and improving the requirements of green production in slaughterhouses. For example, the Chinese utility model patent with publication number: CN217564777U discloses a bone crusher, which can crush bones twice by setting a crushing device, and can achieve the purpose of crushing bones to a certain extent.

[0004] However, the device still has some shortcomings when in use. For example, the bone crusher can only crush bones of the same size. If smaller bones are needed for making soup or livestock feed, the bones processed by the bone crusher need to be processed again. This is not only time-consuming and labor-intensive, and easily increases the additional labor burden, but also greatly reduces the bone processing efficiency and affects the subsequent bone processing.

[0005] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a kind of efficient animal bone crusher.

[0006] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0007] The object of the present invention is to provide a high-efficiency animal bone crusher, which can solve the problem that the bone crusher cannot flexibly adjust the size of the crushed bones.

[0008] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described 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, 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 should fall within the scope of protection of the present invention.

[0043] like Figures 1 to 8As shown, a high-efficiency animal bone crusher in one embodiment of the present invention includes a crusher housing 1, a crushing mechanism 2, a crushing mechanism 3 and an installation box 4.

[0044] Among them, a crushing chamber, a grinding chamber and a discharging chamber are provided in the grinder shell 1, and the crushing chamber, the grinding chamber and the discharging chamber are connected. The bones are first crushed in the crushing chamber, and then enter the grinding chamber for grinding to meet the processing needs of the bones, and finally enter the discharging chamber.

[0045] In addition, a feeding port 101 and a discharging port 102 are installed on the crusher housing 1. The feeding port 101 is connected to the crushing chamber, and the bones to be crushed are put into the crushing chamber through the feeding port 101 for crushing. The discharging port 102 is connected to the discharging chamber, and the crushed bones are finally discharged through the discharging port 102 for subsequent processing of the bones.

[0046] Specifically, a plurality of air outlet holes 103 are provided on the pulverizer housing 1, and the pulverizing chamber is connected with the outside through the air outlet holes 103, so as to discharge the gas in the pulverizing chamber.

[0047] In addition, a control box is installed on the pulverizer housing 1 for controlling the operation of the crushing mechanism 2 , the pulverizing mechanism 3 and the installation box 4 .

[0048] like Figures 1 to 8 As shown, the crushing mechanism 2 is installed in the crushing chamber. The crushing mechanism 2 is used for preliminarily crushing bones so that large bones can be crushed into small bones for subsequent crushing processing of the bones, thereby improving the crushing effect of the bones.

[0049] The crushing mechanism 2 includes a pair of crushing rollers 201, which are engaged with each other. The pair of crushing rollers 201 rotate toward each other to initially crush the bones, and then crush the large bones into several small bones, which is convenient for subsequent crushing of the small bones.

[0050] In addition, the crushing roller 201 is connected with a gear 202, which is arranged outside the crusher housing 1, and a pair of gears 202 mesh with each other. When one of the gears 202 rotates, the other gear 202 also rotates synchronously under the meshing action, so that the pair of crushing rollers 201 can rotate in the opposite direction to crush bones.

[0051] Specifically, one of the crushing rollers 201 is connected to a first pulley, a crushing motor 203 is installed on the side wall of the pulverizer housing 1, a second pulley is connected to the output end of the crushing motor 203, and a belt 204 is connected between the first pulley and the second pulley. When the crushing motor 203 is running, the crushing motor 203 can drive one of the crushing rollers 201 to rotate through the first pulley, the belt 204 and the second pulley, and under the mutual meshing action of the pair of gears 202, the pair of crushing rollers 201 can rotate towards each other, thereby being used to initially crush the bones.

[0052] like Figures 1 to 8 As shown, the crushing mechanism 3 is installed in the crushing chamber and the discharging chamber. The crushing mechanism 3 is used to crush bones so that the bones can meet the processing requirements of food raw materials or livestock feed. At the same time, the crushing mechanism 3 can also crush bones of different sizes according to the different uses of the bones. There is no need to perform secondary processing on the crushed bones, which reduces labor intensity and can also improve the subsequent bone processing efficiency.

[0053] The crushing mechanism 3 includes a support plate 301 , and a plurality of support rods 302 are connected between the support plate 301 and the inner wall of the discharge chamber. The support plate 301 can be fixed in the discharge chamber by the plurality of support rods 302 , and then the crushing motor 303 can be installed.

[0054] In addition, a crushing motor 303 is installed on the support plate 301, and the output end of the crushing motor 303 is connected to the mounting plate 304. When the crushing motor 303 is running, the crushing motor 303 can drive the mounting plate 304 to rotate, and the mounting plate 304 can drive the adjustable grinding disc mechanism to rotate, so as to crush the bones according to needs.

[0055] like Figures 1 to 8 As shown, an adjustable grinding disc mechanism is installed on the mounting plate 304, and the adjustable grinding disc mechanism is arranged in the crushing chamber. The adjustable grinding disc mechanism is used to crush bones of different sizes according to needs.

[0056] The adjustable grinding disc mechanism includes a base 305 , which is fixedly connected to the center of the mounting plate 304 , and the base 305 is used to install a connecting column 306 and a grinding disc 307 .

[0057] In addition, a connecting column 306 is slidably connected in the base 305. By sliding the connecting column 306 in the base 305, the distance between the grinding disc 307 and the side wall of the crushing chamber can be adjusted, and bones of different sizes can be crushed according to needs.

[0058] Specifically, a grinding disc 307 is fixedly connected to the connecting column 306, and the grinding disc 307 cooperates with the side wall of the grinding chamber to grind the crushed bones, and the crushed bones can be used to make soup or livestock feed.

[0059] In addition, an adjustable telescopic member 308 is installed on the mounting plate 304, and the free end of the adjustable telescopic member 308 is arranged in the base 305, and the free end of the adjustable telescopic member 308 is in contact with the connecting column 306. When the adjustable telescopic member 308 is extended, the adjustable telescopic member 308 will lift the connecting column 306, thereby increasing the distance between the grinding disc 307 and the side wall of the crushing chamber, and at this time, larger bones can be crushed. When the adjustable telescopic member 308 is retracted, the grinding disc 307 will retract into the base 305, thereby decreasing the distance between the grinding disc 307 and the side wall of the crushing chamber, and at this time, smaller bones can be crushed to meet different bone crushing requirements.

[0060] like Figures 1 to 8 As shown, a pair of linkage rods 309 are symmetrically connected to the side wall of the connection column 306, and an adjustment groove 310 matching the linkage rod 309 is cut on the base 305. The linkage rod 309 slides in the adjustment groove 310, so that when the base 305 rotates, the connection column 306 and the grinding disc 307 can be driven to rotate, so that the grinding disc 307 and the side wall of the crushing chamber cooperate with each other to crush the bone.

[0061] Among them, a protective cover 311 is connected between the mounting plate 304 and the grinding disc 307 . The protective cover 311 is arranged on the outside of the base 305 . The protective cover 311 is used to protect the adjustment groove 310 to prevent bones from entering the adjustment groove 310 and affecting the adjustment of the grinding disc 307 .

[0062] In addition, a displacement sensor 312 is connected to the bottom of the grinding disc 307, and the displacement sensor 312 can monitor the adjustment distance of the grinding disc 307 so as to adjust and control the size of the crushed bones according to needs.

[0063] Preferably, the displacement sensor 312 is a commercially available product and can be purchased and used directly.

[0064] Specifically, a pair of racks 313 are symmetrically connected to the side wall of the connecting column 306, and a pair of fixed telescopic members 314 are installed in the base 305. The pair of fixed telescopic members 314 correspond to the pair of racks 313 respectively, and the free ends of the fixed telescopic members 314 are connected to the clamping members 315, which are clamped with the racks 313. Through the mutual clamping of the clamping members 315 and the racks 313, the connection column 306 and the base 305 can be further fixed to ensure the stability of the grinding disc 307 when crushing bones.

[0065] When the grinding disc 307 is adjusted, the fixed telescopic part 314 is first controlled to contract so that the engaging part 315 is disengaged from the rack 313. After the grinding disc 307 is adjusted, the fixed telescopic part 314 is controlled to extend so that the engaging part 315 is re-engaged with the rack 313, thereby achieving the fixation of the connecting column 306 and the grinding disc 307.

[0066] like Figures 1 to 8 As shown, the crushing motor 303 is a double-shaft motor, and the crushing motor 303 is also connected to a shaft 316, which is rotatably connected to the support plate 301, and a stirring rod 317 is connected to the side wall of the shaft 316. When the mounting plate 304 rotates, the stirring rod 317 also rotates. When the stirring rod 317 rotates, the bones in the discharge cavity can be stirred, and at the same time, it is convenient to discharge the bones after subsequent crushing, thereby improving the bone discharge efficiency.

[0067] A hollow sleeve 318 is rotatably connected to the outer side of the shaft 316 , and a pair of reinforcing rods 319 are connected between the hollow sleeve 318 and the support plate 301 . The reinforcing rods 319 are used to fix the hollow sleeve 318 to prevent the hollow sleeve 318 from rotating with the shaft 316 .

[0068] In addition, a flow channel 320 is provided in the shaft 316, and a plurality of through holes 321 are provided on the side wall of the shaft 316. The interior of the hollow sleeve 318 is connected to the flow channel 320 through the through holes 321. The gas in the hollow sleeve 318 can enter the flow channel 320 through the through holes 321.

[0069] Specifically, an air channel 322 is provided in the stirring rod 317, and a connecting pipe 323 is connected between the flow channel 320 and the air channel 322, so that the gas in the flow channel 320 can enter the air channel 322 through the connecting pipe 323. A plurality of injection holes 324 are provided on the side wall of the stirring rod 317, and the air channel 322 is connected to the outside through the injection holes 324. The gas entering the air channel 322 can be ejected through the plurality of injection holes 324.

[0070] like Figures 1 to 8 As shown, an installation box 4 is installed on the outer wall of the grinder housing 1, and an air pump 401 is installed in the installation box 4. The air inlet end of the air pump 401 is connected to a three-way pipe, and the air outlet end of the air pump 401 is connected to an air pipe 402. The air pipe 402 passes through one of the support rods 302 and is connected to the hollow sleeve 318.

[0071] When the air pump 401 is running, the air pump 401 draws in external air through the three-way pipe, and the external air enters the hollow sleeve 318 through the air supply pipe 402, enters the flow channel 320 through the through hole 321, and then enters the airway 322 through the connecting pipe 323, and finally sprays to the discharge chamber through a plurality of injection holes 324, so as to blow dry the bones in the discharge chamber. Combined with the stirring action of the stirring rod 317, the air blowing and drying effect of the bones can be greatly improved, the dampness of the bone crushing can be avoided, and the drying pretreatment of the bones can be achieved to a certain extent.

[0072] Preferably, in order to improve the drying effect of the bones in the discharge chamber, a heating mechanism can be provided on the outer side of the gas pipe 402, such as a heating wire surrounding the gas pipe 402. The heating wire can be used to heat the temperature of the flowing gas in the gas pipe 402. Therefore, the gas entering the discharge chamber has a certain amount of heat. The hot gas can better dry the bones in the discharge chamber.

[0073] A pair of gas collecting hoods 403 are connected to the outer wall of the pulverizer housing 1. The pair of gas collecting hoods 403 correspond to the plurality of gas outlets 103 respectively, and the gas collecting hoods 403 cover the outside of the gas outlets 103. The gas in the pulverizing chamber can enter the gas collecting hoods 403 through the gas outlets 103.

[0074] In addition, a connecting pipe 404 is connected between a pair of air collecting hoods 403, and a return air pipe 405 is connected between one of the air collecting hoods 403 and the three-way pipe. When the air pump 401 is running, the air pump 401 delivers gas to the discharge chamber. Since the discharge chamber is connected to the crushing chamber, the gas in the discharge chamber will enter the crushing chamber and flow through the side wall between the grinding disc 307 and the crushing chamber to blow away the bones in the crushing chamber, avoid the bones from being blocked between the grinding disc 307 and the side wall of the crushing chamber, and ensure that the bones can be crushed smoothly.

[0075] Since the return air pipe 405 is connected to the three-way pipe, when the air pump 401 is running, the air pump 401 forms a negative pressure in the pair of air collecting hoods 403 through the return air pipe 405 and the connecting pipe 404. Therefore, the gas in the crushing chamber will enter the air collecting hood 403 through the air outlet 103, and then be sucked into the discharge chamber by the air pump 401. Such a reciprocating cycle can form a gas circulation in the discharge chamber and the crushing chamber, which is not only used to dry the bones in the discharge chamber, but also to blow away the bones in the crushing chamber to prevent the bones from blocking the grinding disc 307, so that the bones can be crushed better, and at the same time, it can also prevent the loss of heat in the gas and improve the overall environmental protection effect.

[0076] In specific use, when it is necessary to process bones, the breaking motor 203 and the crushing motor 303 are operated, and the breaking motor 203 can drive one of the crushing rollers 201 to rotate through the first pulley, the belt 204 and the second pulley, and the rotating crushing roller 201 will drive the gear 202 to rotate synchronously. Since a pair of gears 202 are meshed with each other, when one of the gears 202 rotates, the other gear 202 will also rotate synchronously under the meshing action, and then the pair of crushing rollers 201 can rotate in the opposite direction. The crushing motor 303 can directly drive the mounting plate 304, the base 305, the connecting column 306, the grinding disc 307, the shaft 316 and the stirring rod 317 to rotate.

[0077] The bones to be processed are put into the crushing chamber through the feeding port 101, and the bones are initially crushed under the action of a pair of crushing rollers 201, so that the large bones are divided into several small bones. The small bones will enter the crushing chamber and be crushed under the action of the rotating grinding disc 307 and the side wall of the crushing chamber to meet the requirements.

[0078] If a larger volume of bone is needed, it is necessary to control the extension of the adjustment telescopic member 308, and the adjustment telescopic member 308 will lift the connecting column 306, so that the distance between the grinding disc 307 and the side wall of the crushing chamber can be increased. At this time, the volume of bone entering the discharge chamber is relatively large. If a smaller volume of bone is needed, it is necessary to control the contraction of the adjustment telescopic member 308, and the grinding disc 307 will follow the adjustment telescopic member 308 to contract into the base 305, so that the distance between the grinding disc 307 and the side wall of the crushing chamber can be reduced. At this time, the volume of bone entering the discharge chamber is relatively small. The present application can crush bones of different sizes according to the different bone processing needs, so as to meet the processing requirements of different bones, avoid secondary processing of bones, reduce labor intensity, and also improve the subsequent bone processing efficiency.

[0079] The crushed bones will enter the discharge chamber. Since the stirring rod 317 rotates with the shaft 316, the stirring rod 317 can stir and mix the bones in the discharge chamber. The air pump 401 is operated. The air pump 401 extracts external air through the three-way pipe. The external air enters the hollow sleeve 318 through the air delivery pipe 402, enters the flow channel 320 through the through hole 321, and then enters the airway 322 through the connecting pipe 323. Finally, it is sprayed into the discharge chamber through a plurality of spray holes 324 to blow and dry the bones in the discharge chamber. Combined with the stirring effect of the stirring rod 317, the air blowing and drying effect of the bones can be greatly improved, and the dampness of the bones when they are crushed can be avoided. To a certain extent, the drying pretreatment of the bones can be achieved.

[0080] Since the discharge chamber is connected to the crushing chamber, and the return air pipe 405 is connected to the three-way pipe, when the air pump 401 is running, the air pump 401 will form a negative pressure in a pair of air collecting hoods 403 through the return air pipe 405 and the connecting pipe 404. Therefore, the gas in the discharge chamber will enter the crushing chamber, and flow through the side wall between the grinding disc 307 and the crushing chamber, which is used to blow away the bones in the crushing chamber, avoid the bones from being blocked between the grinding disc 307 and the side wall of the crushing chamber, and ensure that the bones can be crushed smoothly. Subsequently, the gas in the crushing chamber will enter the air collecting hood 403 through the air outlet 103, and then be sucked into the discharge chamber by the air pump 401. This reciprocating cycle can form a gas circulation in the discharge chamber and the crushing chamber, which is not only used to dry the bones in the discharge chamber, but also to blow away the bones in the crushing chamber, avoid the bones from blocking the grinding disc 307, and make the bones better crushed.
