Description

Technical Field

[0001] The invention belongs to the technical field of crushing equipment, in particular to a crusher for dead animals. Background Art

[0002] The carcasses of animals that died of natural causes or epidemic diseases often carry a variety of pathogens. If they are not handled or handled improperly, the carcasses will quickly decompose and emit a foul odor, causing pathogenic microorganisms to pollute the air, water sources and soil, causing the spread and spread of diseases. At the same time, people who have direct or indirect contact with them are likely to be infected, so they usually need to be rendered harmless, and crushing equipment is required during the harmless treatment process.

[0003] A Chinese patent with publication number CN217663559U discloses a crusher for harmless disposal of dead animals, including a body, a top cover and a crushing roller, a carrying box is installed on one side of the body, the top cover is installed on the top of the carrying box, fixing buckles are installed on both sides of the bottom of the top cover, a UV lamp is connected in the fixing buckle, and connecting seats are installed on both sides of the carrying box and the top cover; by arranging the fixing buckle and the UV lamp, the UV lamp can be installed on the bottom of the top cover through the fixing buckle, and then the light emitted by the UV lamp is used to irradiate and sterilize the inside of the carrying box, so as to avoid bacteria overflowing from the carrying box and affecting the working environment, and to prevent safety hazards; by arranging a cavity, a collecting box and a slide rail, the collecting box can enter the cavity along the slide rail, and the crushed animal carcasses can be collected through the collecting box, without the need for external equipment, which is convenient to use and improves the practicality of the device.

[0004] In the current existing technology, when sterilization is performed by ultraviolet lamps, since the ultraviolet lamps are installed in the fixing buckles at the bottom of the top cover, the ultraviolet lamps can mainly irradiate and sterilize the bacteria on the surface of the animals. As for the bacteria in the internal organs of the animals, they may not have time to be sterilized and will directly enter the next process as they are crushed by the crushing rollers, resulting in incomplete sterilization, which will cause pollution to the environment when the materials are unloaded.

[0024] When the sterilization unit provided by the present invention is used, the sterilization box 2 and the heating cylinder 3 are provided to facilitate the solid-liquid separation of the crushed animal. First, the sealing plate 44 is opened to transport the dead animal's body to the crushing bin, and then the sealing plate 44 is closed. The dead animal's body is crushed to form minced meat and blood water through the cooperation of the first crushing roller 424 and the second crushing roller 425. Under the action of gravity, the minced meat and the blood water fall into the conveying cylinder 1, and the first spiral blade 13 conveys the minced meat and the blood water. Since the bottom of the conveying cylinder 1 is provided with a filter hole 16, the blood water will flow into the sterilization box 2 through the filter hole 16, and the minced meat is transported to the position of the heating cylinder 3 with the first spiral blade 13. The heating cylinder 3 is set to a high temperature, and the minced meat is sterilized by the high temperature. After the sterilization is completed, it can be discharged through the lower hopper 17; disinfectant is input into the disinfection box 2 through the liquid inlet pipe 21, and the disinfectant and the blood water are fully mixed under the stirring of the stirring paddle 24 to achieve sterilization and disinfection of the blood water; After the crushing is completed, when the first crushing roller 424 and the second crushing roller 425 crush the dead animals, the minced meat has a certain stickiness and is easy to adhere to the first crushing roller 424 and the second crushing roller 425. It is necessary to flush the minced meat through the water pipe 431 to clean it. During the cleaning process, the two blocking plates 25 should be moved to the middle to block the filter holes 16, so that the water flows through the conveying cylinder 1, and the inside of the conveying cylinder 1 can also be cleaned.

[0025] like Figure 3 and Figure 5 As shown, one end of the conveying cylinder 1 is fixedly connected to the first motor 11 through a mounting plate, the output shaft of the first motor 11 is rotatably connected to the conveying cylinder 1 through a bearing, the output shaft of the first motor 11 is fixedly connected to a rotating rod 12, the end of the rotating rod 12 away from the first motor 11 is rotatably connected to the inner wall of the conveying cylinder 1, the first spiral blade 13 and the second spiral blade 14 are both fixedly connected to the rotating rod 12, and the installation directions are opposite; the end of the conveying cylinder 1 away from the disinfection box 2 is fixedly connected to a fixing plate 15; the end of the conveying cylinder 1 close to the fixing plate 15 is connected and fixedly connected to a lower hopper 17, and the lower hopper 17 is arranged at the intersection of the first spiral blade 13 and the second spiral blade 14.

[0026] When the first spiral blade 13 and the second spiral blade 14 provided by the present invention are in use, during the conveying process, by turning on the first motor 11, the first motor 11 drives the first spiral blade 13 and the second spiral blade 14 to rotate through the output shaft, and the minced meat is conveyed to the position of the heating cylinder 3 and the lower hopper 17 through the first spiral blade 13. However, the end of the first spiral blade 13 is easily squeezed with the conveying cylinder 1, resulting in part of the minced meat remaining at the end of the first spiral blade 13. By providing the second spiral blade 14, the minced meat at the end of the conveying cylinder 1 can be conveyed forward, thereby ensuring that the minced meat eventually falls from the intersection of the first spiral blade 13 and the second spiral blade 14, and is discharged through the lower hopper 17 to the next process or the receiving box.

[0027] like Figure 4 As shown, a third motor 254 is fixedly connected to the side wall of the disinfection box 2; a bidirectional ball screw 253 is rotatably connected between the inner walls on both sides of the disinfection box 2, and the output shaft of the third motor 254 is fixedly connected to one end of the bidirectional ball screw 253; two movable plates 251 are threadedly connected to the bidirectional ball screw 253, and the sealing plates 25 are respectively fixedly connected to the top of the movable plates 251, and the top of the sealing plates 25 is in contact with the bottom of the conveying cylinder 1.

[0028] The blocking plate 25 provided by the present invention is used to block the filter hole 16 when in use. During the crushing process, due to the seepage of blood and water, the blocking plate 25 needs to be moved toward the two ends of the two-way ball screw 253 to keep the filter hole 16 flowing; during the cleaning process, in order to ensure that the conveying cylinder 1 and the crushing bin 4 are flushed together, the blocking plate 25 needs to be moved toward the center of the two-way ball screw 253 so that the filter hole 16 is blocked; when the blocking plate 25 moves, the third motor 254 needs to be turned on, and the third motor 254 drives the two-way ball screw 253 to rotate through the output shaft, and drives the movable plate 251 to move in the opposite direction through the two-way ball screw 253, thereby realizing the blocking and circulation functions of the filter hole 16.

[0029] like Figure 1 and Figure 6 As shown, the first crushing roller 424 and the second crushing roller 425 are both rotatably connected to the inner wall of the crushing bin through the roller shaft; one end of the first crushing roller 424 extends to the outside of the crushing bin 4 and is fixedly connected to the first gear 422; one end of the second crushing roller 425 extends to the outside of the crushing bin 4 and is fixedly connected to the second gear 423; the first gear 422 is meshed with the second gear 423; the first crushing roller 424 and the second crushing roller 425 are symmetrical about the center of the crushing bin 4; an L-shaped plate 421 is fixedly connected to the outer wall of the crushing bin 4, a fourth motor 42 is fixedly connected to the L-shaped plate 421, and the output shaft of the fourth motor 42 is fixedly connected to one end of the roller shaft.

[0030] The first gear 422 and the second gear 423 provided by the present invention are used to drive the first crushing roller 424 and the second crushing roller 425 to rotate in opposite directions when in use. By turning on the fourth motor 42, the roller shaft is driven to rotate by the output shaft of the fourth motor 42, the second gear 423 is driven to rotate by the roller shaft, the first gear 422 is driven to rotate by the second gear 423, and the connected roller shaft is driven to rotate by the first gear 422. The two roller shafts respectively drive the connected first crushing roller 424 and the second crushing roller 425 to rotate, thereby realizing the crushing function of dead animals.

[0031] like Figure 6 As shown, scraper blades 41 are fixedly connected to the inner walls of both sides of the crushing bin 4, and the scraper blades 41 cooperate with the first crushing roller 424 and the second crushing roller 425 respectively.

[0032] The scraper blade 41 provided by the present invention is used to receive animals and clean rollers when in use. When dead animals are crushed, some meat pieces or minced meat will fall on both sides. The scraper blade 41 is provided to receive the meat pieces to prevent them from falling directly into the conveying cylinder 1. The scraper blade 41 cooperates with the first crushing roller 424 and the second crushing roller 425 respectively, so as to scrape off the minced meat on the first crushing roller 424 and the second crushing roller 425 to reduce the adhesion of the minced meat.

[0033] like Figure 1 and Figure 8 As shown, a side plate 443 is fixedly connected to the outer wall of the crushing bin 4, a second reciprocating screw rod 441 is rotatably connected between the side plate 443 and the crushing bin 4 via a bearing, and the sealing plate 44 is threadedly connected to the second reciprocating screw rod 441; two vertical rods 442 are fixedly connected between the side plate 443 and the crushing bin 4, and the bottom end of the sealing plate 44 is slidably connected to the two vertical rods 442; a sixth motor 444 is provided at the bottom of the side plate 443, and the output shaft of the sixth motor 444 is fixedly connected to the bottom of the second reciprocating screw rod 441.

[0034] The sealing plate 44 provided by the present invention is used to seal the crushing bin when in use. In order to prevent the overflow of pathogens and exhaust gas when the animal is crushed, the sixth motor 444 needs to be turned on, and the second reciprocating screw rod 441 is driven to rotate by the output shaft of the sixth motor 444. The sealing plate 44 is driven to reciprocate up and down by the second reciprocating screw rod 441. The sealing plate 44 slides on the vertical rod 442 and the crushing bin, and the sealing plate 44 is limited in the vertical direction by the vertical rod 442 for stable movement.

[0035] like Figure 3 and Figure 7 As shown, a first reciprocating screw rod 435 is rotatably connected between the inner walls on both sides of the top of the crushing bin 4 through bearings, a moving block 433 is threadedly connected to the first reciprocating screw rod 435, a water spray pipe 431 is sleeved on the bottom of the moving block 433 through a connecting plate 434, one end of the water spray pipe 431 is connected and fixedly connected to a telescopic pipe 432, and one end of the telescopic pipe 432 is connected and fixedly connected to the crushing bin; two cross bars 436 are slidably connected to the moving block 433, and the two ends of the cross bars 436 are respectively fixedly connected to the inner walls of the crushing bin; a fifth motor 43 is fixedly connected to the outer wall of the crushing bin, and the output shaft of the fifth motor 43 is fixedly connected to one end of the first reciprocating screw rod 435.

[0036] The water spray pipe 431 provided by the present invention is used for washing the minced meat on the first crushing roller 424 and the second crushing roller 425 when in use. The first crushing roller 424 and the second crushing roller 425 will produce minced meat when crushing dead animals. The minced meat will be stuck on the rotating parts of the first crushing roller 424 and the second crushing roller 425 for a long time. If it is not cleaned in time, the first crushing roller 424 and the second crushing roller 425 will be stuck, affecting the rotational crushing. It is necessary to turn on the fifth motor 43, and the first reciprocating screw rod 435 is driven to rotate by the fifth motor 43, and the moving block 433 is driven to reciprocate by the first reciprocating screw rod 435. The moving block 433 drives the water spray pipe 431 and the telescopic tube 432 to reciprocate through the connecting plate 434. Water is sprayed through the telescopic tube 432 and the water spray pipe 431, so as to realize the washing of the first crushing roller 424 and the second crushing roller 425. During the washing process, the rotation of the first crushing roller 424 and the second crushing roller 425 should be maintained.

[0037] like Fig. 9 As shown, the other end of the water spray pipe 431 is rotatably connected to a rotating spray head 437 , and an impeller 438 is fixedly connected to the inner wall of the rotating spray head 437 .

[0038] When the rotary nozzle 437 provided by the present invention is in use, the water in the water spray pipe 431 will pass through the impeller 438 when it is discharged, and the impeller 438 will be driven to rotate under the action of the water flow, and the rotary nozzle 437 will be driven to rotate through the impeller 438. When the water flows into the rotary nozzle 437, the external air pressure forces the water flow to speed up the discharge, thereby increasing the water discharge speed and achieving the effect of automatic pressurization.

[0039] like Figure 4 As shown, two guide rods 252 are fixedly connected to the inner side wall of the disinfection box 2 , and the movable plates 251 slide on the two guide rods 252 .

[0040] When the guide rod 252 provided by the present invention is in use, when the movable plate 251 is moving, the movable plate 251 slides on the guide rod 252, and the guide rod 252 limits the movable plate 251 to move in the horizontal direction.

[0041] Working principle: first open the sealing plate 44, transport the dead animal's body to the crushing bin, then close the sealing plate 44, turn on the fourth motor 42, drive the roller shaft to rotate through the output shaft of the fourth motor 42, drive the second gear 423 to rotate through the roller shaft, drive the first gear 422 to rotate through the second gear 423, drive the connected roller shaft to rotate through the first gear 422, and the two roller shafts respectively drive the connected first crushing roller 424 and second crushing roller 425 to rotate, and through the cooperation of the first crushing roller 424 and the second crushing roller 425, the dead animal's body is crushed to form minced meat and blood water, Under the action of gravity, the minced meat and blood water fall into the conveying cylinder 1, and the first spiral blade 13 conveys the minced meat and blood water. Since the bottom of the conveying cylinder 1 is provided with a filter hole 16, the blood water will flow into the disinfection box 2 through the filter hole 16, and the minced meat is conveyed to the position of the heating cylinder 3 along with the first spiral blade 13. The heating cylinder 3 is set to a high temperature, and the minced meat is sterilized by the high temperature. After the sterilization is completed, it can be discharged through the lower hopper 17; the disinfectant is input into the disinfection box 2 through the liquid inlet pipe 21, and the disinfectant and the blood water are fully mixed under the stirring of the stirring paddle 24 to achieve the sterilization and disinfection of the blood water; During the conveying process, by turning on the first motor 11, the first motor 11 drives the first spiral blade 13 and the second spiral blade 14 to rotate through the output shaft, and the minced meat is conveyed to the position of the heating cylinder 3 and the lower hopper 17 through the first spiral blade 13. However, the end of the first spiral blade 13 is easily squeezed with the conveying cylinder 1, resulting in part of the minced meat remaining at the end of the first spiral blade 13. By providing the second spiral blade 14, the minced meat at the end of the conveying cylinder 1 can be conveyed forward, thereby ensuring that the minced meat finally falls from the intersection of the first spiral blade 13 and the second spiral blade 14, and is discharged to the next process or the receiving box through the lower hopper 17; After the crushing is completed, when the first crushing roller 424 and the second crushing roller 425 crush the dead animals, the minced meat has a certain stickiness and is easy to adhere to the first crushing roller 424 and the second crushing roller 425. It is necessary to flush the minced meat through the water spray pipe 431 to clean the minced meat. During the cleaning process, the two blocking plates 25 should be moved toward the middle, and the third motor 254 needs to be turned on. The third motor 254 drives the bidirectional ball screw 253 to rotate through the output shaft, and drives the moving plate 251 to move in the opposite direction through the bidirectional ball screw 253, so as to realize the blocking and circulation function of the filter hole 16, block the filter hole 16, so that the water flows through the conveying cylinder 1, and the inside of the conveying cylinder 1 can also be cleaned; During cleaning, it is necessary to turn on the fifth motor 43, and the first reciprocating screw rod 435 is driven to rotate by the fifth motor 43, and the moving block 433 is driven to reciprocate by the first reciprocating screw rod 435. The moving block 433 drives the water spray pipe 431 and the telescopic tube 432 to reciprocate through the connecting plate 434, and water flows out through the telescopic tube 432 and the water spray pipe 431, so as to flush the first crushing roller 424 and the second crushing roller 425, and during the flushing process, the first crushing roller 424 and the second crushing roller 425 should be kept rotating.
