Description

Technical Field

[0001] The present invention relates to the field of aquaculture excrement treatment, and more particularly to an aquaculture excrement treatment device. Background Art

[0002] At present, the domestic chicken farming industry is gradually developing towards large-scale centralized farming. As thousands of chickens are concentrated in one chicken house, the cleaning of chicken manure becomes a very critical issue. If the chicken manure is not cleaned in time, it will cause a strong odor in the chicken house and even affect the normal growth of the chickens.

[0003] At present, there are multiple groups of chicken cages set horizontally on the chicken racks. Most of the chicken cages have mesh holes at the bottom, and the chicken manure falls through the mesh holes. There are two main ways to deal with chicken manure: the first is manual cleaning, and the second is to send the manure out by conveyor belt.

[0004] Both methods have certain defects. The first method requires manual operation. When the breeding density in the chicken house is high, the amount of chicken manure excretion is large, and it needs to be cleaned many times a day. Each cleaning is time-consuming and labor-intensive, with high labor workload and low labor efficiency.

[0005] The second method can send the feces out through the conveyor belt and collect them in a simple and unified manner; however, the current equipment does not carry out targeted cleaning of the conveyor belt, resulting in a lot of feces remaining on the conveyor belt. After a long period of accumulation, it may clump, making subsequent cleaning more inconvenient; moreover, simple collection without rapid transfer or processing will also cause accumulation, and the generated odor will also remain in the chicken house. The overall level of intelligent automation is not high and needs to be improved. Summary of the Invention

[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] like Figures 1 to 4As shown, a specific embodiment of the present invention discloses a manure processing equipment for livestock farming, including a conveyor belt 100, a machine cover 200, a manure scraping device 300, a conveying device 400, a flushing device 500, and a deodorizing device 600; the manure scraping device 300, the conveying device 400, the flushing device 500, and the deodorizing device 600 are all installed on the machine cover 200; one end of the conveyor belt 100 extends into the machine cover 200, the manure scraping device 300 is used to scrape the manure on the conveyor belt 100 and guide the manure to the conveying device 400, and the conveying device collects the manure. The feces are transported to the outside; the flushing device 500 includes a first water spray pipe 510, a second water spray pipe 520, and at least one third water spray pipe 530. The first water spray pipe 510 is used to spray water to flush the feces scraping device 300, the second water spray pipe 520 is used to spray water to flush the belt surface of the conveyor belt 100, and the third water spray pipe 530 is used to spray water to flush the conveying device 400; the deodorizing device 600 uses the third water spray pipe 530 to exhaust the interior of the hood 200, and uses the first water spray pipe 510 to spray and form an air curtain to prevent the odor from being discharged.

[0041] The above-mentioned livestock manure processing equipment has a novel structure and includes a conveyor belt, a machine cover, a manure scraping device, a conveying device, a flushing device, and a deodorizing device. The conveyor belt can timely transfer manure and drive the manure to a collection location. The manure scraping device can scrape off manure adhering to the conveyor belt to prevent manure from being retained on the conveying device and preventing subsequent agglomeration. The scraped manure falls onto the conveying device, which uniformly sends the manure to the outside through the conveying device for timely transfer, thereby preventing manure accumulation and the generation of odor.

[0042] The flushing device can spray water on the scraper, conveyor belt surface and conveyor device. It can perform regular comprehensive cleaning or clean a single structure, effectively preventing feces from remaining on equipment components and further preventing caking.

[0043] The deodorizing device can extract and purify the odor inside the hood, further reducing the emission of odor. The deodorized gas can also be used to form an air curtain to prevent the emission of odor, making clever use of it and reducing energy consumption.

[0044] Furthermore, the deodorizing device utilizes the third water spray pipe and the first water spray pipe as components for exhaust and air injection, respectively, thereby realizing component sharing, making better use of the space inside the hood, and reducing structural costs.

[0045] The design and coordination of the overall structure can achieve highly intelligent automated actions, and can transfer and clean feces in a timely manner to prevent feces from being retained on the conveying equipment and avoid caking problems; it can also transfer the collected feces and carry out targeted odor extraction and treatment to prevent odor from staying in the breeding room.

[0046] Furthermore, if Figure 4 、 Figure 5 As shown, the conveying device 400 includes a screw rod 410, a first motor 420, and a trough structure 430; a vertically arranged support plate 210 is fixedly provided inside the hood 200; the screw rod 410 is rotatably mounted in the hood 200, one end of the screw rod extends through the outside of the hood, and a first sprocket is fixedly provided at the end thereof, a second sprocket is fixedly provided on the output shaft of the first motor, the first sprocket and the second sprocket are connected by a chain transmission, and the screw rod 410 is driven to rotate by the first motor 420; the trough structure 430 includes a pushing mechanism 433, a first bracket 431, and a second bracket 432, the first bracket 431 and the second bracket 432 are located below the screw rod 410, and the first bracket and the second bracket are both provided with an arc groove adapted to the outer diameter of the screw rod; the pushing mechanism 433 is mounted on the support plate 210, the first bracket 431 is mounted on the pushing mechanism 433, and the second bracket 432 is fixed to the inner wall of the hood 200 by bolts, The arc-shaped grooves of the first bracket 431 and the second bracket 432 are arranged relative to each other to form a material trough 434 with a semicircular cross-section. The pushing mechanism drives the first bracket to move horizontally, and the first bracket and the second bracket form an opening and closing action; the material trough serves as the main receiving part for feces, and the feces dropped from the scraper falls into the material trough, and then the rotating screw rod drives the feces to move until it is sent to the outside; a drain pipe is connected to the bottom of the side wall of the hood, and a sixth solenoid valve is provided on the drain pipe; the first bracket is driven by the push rod motor to realize the opening and closing between the first bracket and the second bracket. Under normal conditions of receiving and transporting feces, the first bracket and the second bracket are maintained in a connected and closed state; when the screw rod is cleaned, cleaning water can be injected into the closed material trough, and the screw rod is rotated to achieve cleaning; when cleaning is completed, the first bracket is driven to move, so that the first bracket leaves the second bracket and the blocking state is released, so that the cleaning waste water falls below and is discharged through the drain pipe;

[0047] An outlet 220 is formed on the outer wall of the hood 200 at one end of the trough 434. An external discharge pipe 230 is fixedly mounted on the outer wall of the outlet 220. A blocking mechanism 700 is installed at the end of the external discharge pipe 230. During normal feces transfer, the blocking mechanism is released and does not block the bottom of the external discharge pipe. During cleaning of the spiral rod, the blocking mechanism blocks the bottom of the external discharge pipe to prevent the cleaning water from being discharged from the external discharge pipe.

[0048] Furthermore, a water outlet is provided on the bottom surface of the support plate to ensure the normal flow of internal cleaning water and facilitate discharge.

[0049] Furthermore, if Figure 5As shown, the pushing mechanism 433 includes an electric push rod 4331 and a plurality of guide rods 4332. The electric push rod 4331 is fixedly mounted on the support plate 210. A push plate is fixedly provided at the end of the piston rod of the electric push rod. The push plate is supported on the first bracket and fixed by bolts. One end of the guide rod 4332 is fixedly mounted on the first bracket 431. A plurality of guide holes are provided on the support plate corresponding to the guide rods. The free ends of the guide rods are movable through the guide holes. The first bracket is slidably mounted on the support plate through the plurality of guide rods, and the first bracket is driven to move horizontally by the electric push rod to realize the opening and closing between the first bracket and the second bracket.

[0050] Furthermore, a slot is provided at the bottom of the second bracket close to the first bracket side, and an insert plate is fixedly provided at the bottom of the first bracket close to the second bracket side, the shape of the insert plate is adapted to the shape of the slot, and the position corresponds to that, the first bracket is driven by the electric push rod, and the insert plate is correspondingly inserted into the slot, so that a material trough adapted to the spiral rod is formed between the first bracket and the second bracket, and this material trough is used to receive feces, and the feces inside the material trough is pushed to the outside through the spiral rod; due to the provision of the insert plate and the slot, the second bracket can be used to support the first bracket, thereby strengthening the bearing capacity of the entire material trough structure, preventing the second bracket from tilting in the vertical position, reducing the radial force on the electric push rod, and preventing damage to the electric push rod; and, through the cooperation of the insert plate and the slot, the sealing of the connection part can be further strengthened to prevent leakage.

[0051] Furthermore, a first sealing gasket is fixedly provided on the bottom side wall of the first bracket. When the electric push rod drives the first bracket to move and push toward the second bracket, the first sealing gasket seals this part to prevent liquid from seeping out of this part during the cleaning process of the spiral rod, thereby preventing the normal cleaning action of the spiral rod from being affected.

[0052] Furthermore, one end of the spiral rod 410 extends into the outer tube 230, and a ring 240 is hung on the inner wall of the top of the outer tube 230. The inner diameter of the ring is consistent with the diameter of the rod body of the spiral rod. One end of the spiral rod 410 is rotatably hung on the ring 240, and the rod body at the other end passes through the machine cover through a bearing and extends to the outside, thereby limiting the two ends of the spiral rod and providing basic support for the rotation of the spiral rod; the blocking mechanism 700 includes a second motor 710 and a sleeve 720, such as Figure 8As shown, the inner diameter of the sleeve 720 is adapted to the outer diameter of the outer tube 230, and the outer wall of the outer tube is provided with a groove, which is closed around the axis of the outer tube. A plurality of first threaded holes are provided on the sleeve corresponding to the groove, and a first pin is installed at the first threaded hole. The lower end side wall of the first pin is a smooth surface structure, and the bottom of the first pin extends into the groove. The bottom side wall of the first pin slides against the groove wall of the groove, and the sleeve is rotated and clamped on the outer tube. The cooperation between the first pin and the groove allows the sleeve to maintain its rotation and clamping on the outer tube. The drainage pipe has a simple structure and is easy to assemble and disassemble. A baffle 730 is fixed to the outer wall of the port of the sleeve 720. The baffle can block the bottom of the port of the sleeve, and the top surface of the baffle is lower than the axis of the sleeve. The distance from the top surface of the baffle to the axis of the sleeve is less than 1 / 4 of the diameter of the sleeve, which can ensure that the opening maintains a sufficiently large range. When the opening is rotated to the lower position, it can facilitate the discharge of feces. When the baffle is rotated to the lower position, it can maintain the blocking state of the external drainage pipe, prevent the discharge of the internal liquid, and facilitate the cleaning of the spiral rod.

[0053] A gear ring 740 is fixedly provided on the outer wall of the sleeve 720, and a gear 750 is fixedly provided on the output shaft of the second motor 710. The second motor is fixed to the hood through a bracket, and the gear and the gear ring are engaged for transmission, and are driven by the second motor to realize automatic sealing and unblocking actions. It should be noted that the amount of water sprayed is set, and the amount of water accumulated inside the trough will not be higher than the top surface of the baffle, so as to prevent the cleaning water from being discharged from the opening of the sealing mechanism.

[0054] Furthermore, if Figure 6 As shown, the manure scraping device 300 includes a base plate 310, a scraper 320, a tension spring 330, and a rotating shaft 340; the base plate 310 is fixedly mounted on the top surface of the support plate 210, and the rotating shaft is mounted on the base plate through a bearing seat. The bottom of the scraper 320 is bent to form a hook groove 322, the shape of the hook groove is adapted to the shape of the rotating shaft, the rotating shaft 340 is stuck in the hook groove 322 and is fixedly connected by a second pin, and the scraper rotates and swings with the rotating shaft; a first ring buckle 351 is fixedly mounted on the bottom of the side of the scraper 320 close to the conveyor belt 100, and a second ring buckle 352 is fixedly mounted on the top surface of the base plate 310. The first ring buckle 351 and the second ring buckle 352 are fixedly mounted. 2 are connected by a tension spring 330; a narrowed blade portion 321 is provided on the side of the scraper 320 close to the conveyor belt 100. Under the pull of the tension spring, the blade portion 321 of the scraper is placed on the top of the turning area 110 of the conveyor belt 100, the blade portion is tangent to the belt surface, and the inclined lower end of the scraper 320 is located above the edge of the trough 434; because the blade portion is in contact with the belt body, the conveyor belt drives the feces to move. When passing through the turning area, the feces will be scraped onto the scraper, and the feces will move downward along the scraper until it falls into the trough; in addition, the scraper is exerted with force by the tension spring to maintain the scraper against the conveyor belt without affecting the normal rotation of the conveyor belt.

[0055] Furthermore, if Figure 7 As shown, the conveyor belt 100 located inside the hood 200 forms a narrowing corner 120 after being changed in direction by the guide roller. The narrowing corner 120 is located in the downstream section of the turning area 110. The second water spray pipe 520 is arranged on the inner side of the narrowing corner 120. The second water spray pipe is provided with 3 second water spray holes, and the second water spray holes extend along the length direction of the second water spray pipe; one of the second water spray holes is arranged corresponding to the outer wall of the guide roller, and the other two second water spray holes are arranged corresponding to the two side walls of the narrowing corner respectively; setting a narrowing corner can change the direction of the belt body of the conveyor belt to form a recessed area, which can provide an installation position for the second water spray pipe, ensuring that the conveyor belt can be sprayed and flushed twice, and facilitating the second water spray pipe to approach the guide roller, thereby flushing the guide roller. Multiple flushing can reduce the adhesion of feces on the guide roller, and can also ensure that the conveyor belt is effectively flushed and cleaned, effectively preventing feces from adhering to the conveyor belt, and further preventing agglomeration problems.

[0056] Furthermore, if Figure 2 、 Figure 3 As shown, the flushing device 500 includes a booster pump 540, a first water spray pipe 510, a second water spray pipe 520, and two third water spray pipes 530; the first water spray pipe, the second water spray pipe, and the third water spray pipe pass through two opposite side walls of the hood and are fixedly mounted on the hood; the first water spray pipe 510 is arranged above the blade portion 321 of the scraper 320, and the first water spray pipe is provided with two first water spray holes, which extend along the length of the first water spray pipe; since the blade portion is the first part of the scraper 320 to be scraped, one of the first water spray holes is required to spray vertically toward the blade portion to perform targeted flushing on the main scraping part and prevent agglomeration in this part; the upper flushing water spray has a certain coverage area, and the other first water spray hole can be tilted to spray toward the middle position of the scraper, providing an impact force moving downward, so as to facilitate the downward movement of the cleaning water carrying feces;

[0057] Two third water spray pipes 530 are provided above the spiral rod 410 and on either side of the spiral rod. Two third water spray holes are provided on the third water spray pipes, and the third water spray holes extend along the length of the third water spray pipes. One of the third water spray holes sprays obliquely toward the top center of the spiral rod, and the other third water spray hole sprays obliquely toward the junction of the spiral rod and the material trough. Water can be sprayed to rinse the spiral rod as well as the trough wall, effectively improving the flushing and cleaning effect.

[0058] The two third water spray pipes 530 are connected through the first confluence pipe 550. The first confluence pipe 550, the first water spray pipe 510, and the second water spray pipe 520 are all connected to the second confluence pipe 560. The second confluence pipe 560 is connected to the water outlet of the booster pump 540. The first water spray pipe 510 is provided with a first solenoid valve 511, the second water spray pipe 520 is provided with a second solenoid valve 521, and the first confluence pipe 550 is provided with a third solenoid valve 551. It is possible to connect a single water spray pipe to work, especially for the second water spray pipe. The second water spray pipe is used to flush and clean the belt body of the conveyor belt. The cleaning frequency is high, and a separate water spray is required to maintain the cleanliness of the conveyor belt and further prevent feces from remaining on the conveyor belt. It should be noted that only the water spray pipe inside the hood is provided with a water spray hole, and the water spray pipe passing through the outside of the hood does not have a water spray hole, ensuring that water spraying and flushing are only performed inside the hood.

[0059] Furthermore, the outer ends of the first water spray hole, the second water spray hole and the third water spray hole are all in a narrowed structure, which can make the sprayed flushing water more concentrated and have a greater impact force, thereby enhancing the flushing and cleaning effect.

[0060] Furthermore, the deodorizing device 600 includes an air pump 650, a deodorizer 660, a third manifold 640, a first air pipe 610, a second air pipe 620, and a third air pipe 630; the ends of the two third water spray pipes 530 away from the first manifold 550 are connected through the third manifold 640, the third manifold 640 is connected to the air inlet of the deodorizer 660 through the first air pipe 610, the air outlet of the deodorizer 660 is connected to the air inlet of the air pump 650 through the second air pipe 620, and the air outlet of the air pump 650 is connected to the first water spray pipe 510 through the third air pipe 630; a fourth solenoid valve 611 is provided on the first air pipe 610, and a fifth solenoid valve 631 is provided on the third air pipe 630; The three water spray pipes perform vacuuming on the spiral rod and the trough, and send the odor to the deodorizer for purification and deodorization, thereby reducing the discharge of odor. During operation, the vacuum pump will inevitably spray air outward, which will be sprayed through the first water spray pipe to form an air curtain to prevent the discharge of odor, making clever use of it to reduce energy consumption. It should be noted that during the process of water spraying and flushing, the fourth solenoid valve and the fifth solenoid valve need to be closed to prevent the flushing water from entering the deodorizer and the vacuum pump along the pipeline to avoid damage to the equipment. When performing normal vacuuming, the corresponding first solenoid valve and the third solenoid valve are closed to prevent the flushing water from entering the first and third water spray pipes during the process of water spraying and flushing by the second water spray pipe, thereby avoiding the synchronous operation of water spraying and vacuuming.

[0061] It should be noted that the deodorizer is a relatively mature gas treatment equipment that can be purchased and used directly on the market, and the specific structure will not be described in detail.

[0062] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various modifications or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
