Description

Technical Field

[0001] This invention relates to a green, intelligent, and healthy pig farming facility. Background Technology

[0002] With improved living standards, people's demand for pork has increased, and pork prices have risen from 6 yuan per jin in 2000 to 30 yuan per jin in 2022. Pork prices need to be effectively controlled. The main reason for the price increase is the insufficient supply of live pigs, which leads to demand far exceeding supply, thus causing pork prices to skyrocket.

[0003] Traditional pig farming uses pigsties, which are built inside pig houses. Pigs are raised in these pig houses and fed manually. However, manual feeding is inefficient. Therefore, to meet market demand, there are too many pig houses and manual feeding cannot meet the needs.

[0004] Therefore, existing technologies use feeders for feeding. However, the feeder needs to slide along the pigpen, requires manual operation, and the amount of feed to be fed each time needs to be determined. When the feeder's hopper is empty, it needs to return to its original position to be refilled before the next feeding. This feeding method is very cumbersome, requiring operators to move back and forth with the feeder, and the amount of feed fed each time is not accurate.

[0005] To address this, we have designed a green, intelligent, and healthy pig farming facility that enables automated feeding, avoids waste caused by excessive feed intake, and prevents pigs from getting sick due to overfeeding. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a green and intelligent healthy pig farming facility that can realize automated feeding, avoid waste caused by excessive feed feeding, and avoid pig diseases caused by overfeeding.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A green, intelligent, and healthy pig farming facility includes a controller, and also includes...

[0009] A feed storage device, erected on the ground, stores the feed supplied to the pigs.

[0010] A screw conveyor, in conjunction with the storage device, lifts the feed within the storage device upwards.

[0011] A screw conveyor, in conjunction with a screw elevator, provides feed that has been lifted upwards by the screw elevator and fed into the screw conveyor, where it is then transported.

[0012] A material return device is installed at the end of the screw conveyor and is connected to the material storage device.

[0013] Multiple material distribution devices are provided, and these multiple material distribution devices are connected in series with the screw conveyor.

[0014] The main water pipe is closed at one end and connected to the water supply equipment at the other end, supplying water to the distribution device.

[0015] Both the screw elevator and the screw conveyor are controlled by the controller.

[0016] Preferably, the storage device includes a frame plate, a discharge hopper is provided at the front end of the frame plate near the bottom, a return hopper is provided at the rear end of the frame plate, a material inlet is provided on the surface of the vertical plate connecting the discharge hopper and the return hopper, the screw conveyor passes through the discharge hopper, the inlet of the screw conveyor is located in the discharge hopper, the screw conveyor is installed at the front end of the frame plate, the bottom surface of the return hopper slopes downward to the material inlet, and the return device is connected to the return hopper.

[0017] Preferably, the return material device includes a return material pipe, a connecting pipe at the bottom of the return material pipe, and an inclined pipe connected to the connecting pipe. The end of the inclined pipe away from the connecting pipe extends downward at an angle to the rear of the screw conveyor. The lower end of the inclined pipe is connected to the return material pipe. The end of the return material pipe away from the inclined pipe is also downward at an angle and connected to the return material bin. The return material pipe is installed at the end of the screw conveyor.

[0018] Preferably, the feeding device includes a feeding pipe with a first connecting pipe at its bottom. An electrically controlled valve is installed through the first connecting pipe. Two side plates are symmetrically arranged on the outer wall of the first connecting pipe, and an electronic weighing scale is installed on the side plates. A feeder is movably arranged below the first connecting pipe, with a guide rod at its upper end. The guide rod passes upward through the side plates and engages with a pressure plate, which acts on the electronic weighing scale. Both the electrically controlled valve and the electronic weighing scale are electrically connected to the controller. The weight of the feeder is measured by the electronic weighing scale. When the electrically controlled valve opens, the feed conveyed by the screw conveyor falls into the feeder. As the feed enters, the weight of the feeder increases, and the weight of the feeder is fed back to the controller in real time through the electronic weighing scale. When the weight reaches the preset weight of the controller, the controller controls the electrically controlled valve to close, stopping the feeding. The main water pipe cooperates with the feeder.

[0019] Preferably, the feeder includes a storage hopper with a lid at the top and a conical material gathering section at the bottom. A discharge pipe is located at the bottom of the material gathering section, and a drive motor is installed at the lower end of the discharge pipe. The output end of the drive motor is inserted into the discharge pipe and fitted with a spiral blade. The spiral blade ascends through the discharge pipe and the material gathering section before being inserted into the storage hopper. A discharge nozzle is located near the lower part of the outer wall of the discharge pipe, through which feed is discharged into the pigsty. An assembly pipe is located at the top of the lid, and a first connecting pipe is inserted into the assembly pipe and fits with it with a clearance.

[0020] Preferably, an annular water tank is installed at the inner top of the bucket lid, and a water distribution pipe connecting the water tank is provided at the top of the bucket lid. A first electrically controlled valve connected to the controller is installed on the water distribution pipe. A flexible hose is fitted between the water distribution pipe and the main water pipe. An annular water distribution ring is provided near the top of the inner side of the storage bucket. A drain hole is provided at the bottom of the water distribution ring. A sealing ring is embedded in the inner wall of the water distribution ring. An annular baffle is provided on the outer wall of the water tank. After the water tank is inserted into the water distribution ring, it contacts the sealing ring to form a seal. After the baffle contacts the water distribution ring, it limits the downward movement of the water tank. A drain hole is provided on the outer wall of the water tank above the baffle. The drain hole is inclined towards the inner wall of the storage bucket.

[0021] Preferably, the inner diameter of the feed pipe is larger than the inner diameter of the screw conveyor. An inner pipe is installed inside the feed pipe, and the inner diameter of the inner pipe is the same as that of the screw conveyor. End plates are provided at both ends of the inner pipe, and the end plates are fixed to the inner wall of the feed pipe. A gap is formed between the inner pipe and the feed pipe under the support of the end plates. The first connecting pipe is inserted upwards into the feed pipe and connects to the inner pipe. A stepped groove is provided at the upper part of the inner pipe, and a hot air mesh is installed in the stepped groove. The mesh size is 40-60 mesh. A frame is installed outside the inner tube, on the outer side of the stepped groove. The frame contacts the inner wall of the feed tube. A maintenance box is provided at the top of the feed tube, which is connected to the interior of the feed tube and corresponds to the hot air mesh. A cover is detachably installed at the upper end of the maintenance box. A hot air blower is installed inside the maintenance box. An air inlet slot is provided above the hot air blower on the outer wall of the maintenance box. A hanging bracket is installed on the outer side of the maintenance box.

[0022] The intelligent feeding of pigs is achieved through this device in the following ways:

[0023] Step 1: Classify pigs according to their type and body shape. For example, separate pigs with high feed requirements from those with low feed requirements, and separate lean pigs from overweight pigs.

[0024] Step 2: Determine the number of pigs in each pen in the pigsty, and determine the daily feed amount based on their breed, type and body size. Enter the required feed amount into the controller.

[0025] Step 3: Each day, feed only needs to be added to the storage device. When the feeding time arrives, the controller activates the screw conveyor to lift the material to the screw conveyor. The screw conveyor's conveying capacity is greater than the screw elevator's lifting capacity to prevent damage to the screw conveyor due to excessive feed input. The screw conveyor then transports the feed to the return device. During this process, the feed passes through multiple distribution devices, falling from the screw conveyor into the distribution devices. The weight of the feeder is monitored in real-time by an electronic scale. Because the feeder uses a screw blade for feeding, the amount of feed leaking through the feeder when the screw blade stops is limited and negligible. When the electronic scale detects that the weight of the feeder has reached the feeding amount set by the controller... When the controller closes the electrically controlled valve, the feed conveyed by the screw conveyor cannot be discharged through the closed valve. Using this method, when the weight of all connected feeding devices reaches the target, the screw elevator stops, while the screw conveyor continues to run. The duration of continuous operation is determined based on the length of the screw conveyor to facilitate the discharge of residual feed from the screw conveyor. After discharge, this material is returned to the storage device via a return device. At this point, the controller stops the screw conveyor and opens the electrically controlled valve, allowing the excess feed accumulated above the valve to be discharged downwards into the feeder. Considering this excess feed, the controller can modify the closing weight of the electrically controlled valve to control the feed delivery amount as precisely as possible.

[0026] Step 4: Based on the required number of feedings per day, control the start time and duration of the drive motor via the controller until the feed is dispensed.

[0027] Step 5: Repeat steps 3 to 5 times to record the feed residue in each pen of the pigsty. For pens with residual feed, reduce the amount of feed given.

[0028] The beneficial effects of this invention are:

[0029] One advantage is that this device uses a single storage unit, so operators only need to put the required feed into the storage unit each day, eliminating the need to put it into each pigpen individually, making the operation much easier.

[0030] Secondly, the automatic material conveying is achieved through the cooperation of screw elevator and screw conveyor. In addition, the return device recovers the feed that cannot be put in or the excess feed from the screw conveyor to the storage device, and continues to the next conveying until all the feed is put into the distribution device.

[0031] Thirdly, the controller can set the feed storage amount for each feeding device. When the set amount is reached, the electronically controlled valve is closed, preventing the screw conveyor from feeding that feeding device. This allows for precise control of the feed amount in each pigpen, avoiding overfeeding that leads to pig bloating and illness, as well as the problem of feed waste caused by overfeeding.

[0049] See Figure 1 and Figure 2 The illustrated green intelligent healthy pig farming facility includes a controller, and also includes,

[0050] The feed storage device 1 is erected on the ground, and the feed supplied to the pigs is stored in the feed storage device 1.

[0051] The screw conveyor 2, in conjunction with the storage device 1, lifts the feed inside the storage device 1 upwards.

[0052] A screw conveyor 3, in conjunction with a screw elevator 2, feed lifted upwards by the screw elevator 2 is fed into the screw conveyor 3 and transported therethrough.

[0053] The return material device 4 is installed at the end of the screw conveyor 3 and is connected to the storage device 1.

[0054] Material distribution device 5, wherein multiple material distribution devices 5 are provided, and multiple material distribution devices 5 are connected in series with screw conveyor 3.

[0055] The main water pipe 6 is closed at one end and connected to the water supply equipment at the other end. The main water pipe 6 supplies water to the distribution device 5.

[0056] Both the screw elevator 2 and the screw conveyor 3 are controlled by the controller.

[0057] In addition to a dedicated drinking water system, the pigsty is also equipped with an extra main water pipe 6. The main water pipe 6 can be used to rinse the feed distribution device 5 with additional water to keep it clean and reduce the chance of pigs getting sick.

[0058] By placing feed at a single location on the ground, the feed is lifted by a screw elevator and transported by a screw conveyor. During the transport process, feed is fed to the distribution device 5 one by one. The distribution device calculates the amount of feed entering the pigsty. When the set amount of the controller is reached, the distribution device 5 is turned off, and the feed in the screw conveyor 3 cannot be transported to the distribution device 5. Compared with traditional technology, this avoids supplying too much feed to a single pigsty.

[0059] See Figure 2 As shown, the storage device 1 includes a frame plate 101. A discharge hopper 102 is provided at the front end of the frame plate 101 near the bottom. A return hopper 103 is provided at the rear end of the frame plate 101. A feed inlet 104 is provided on the surface of the vertical plate 101, connecting the discharge hopper 102 and the return hopper 103. The screw conveyor 2 passes through the discharge hopper 102, and the feed inlet of the screw conveyor 2 is located inside the discharge hopper 102. The screw conveyor 3 is installed at the front end of the frame plate 101. The bottom surface of the return hopper 103 slopes downward to the feed inlet 104. The return device 4 is connected to the return hopper 103.

[0060] The storage device 1 includes a discharge bin 102 for storing materials and a return bin 103 for recycling materials. The recycled materials are resupplyed to the storage bin 102. Even if the material falling accuracy is low during the conveying process of the screw conveyor, the feeding needs of each distribution device 5 can be met through cyclic feeding. It also solves the technical problem of manually transferring excess feed.

[0061] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the return material device 4 includes a return material pipe 401, a connecting pipe 402 is provided at the bottom of the return material pipe 401, and an inclined pipe 403 is connected to the connecting pipe 402. The end of the inclined pipe 403 away from the connecting pipe 402 extends downward at an incline to the rear of the screw conveyor 3. The lower end of the inclined pipe 403 is connected to a return material pipe 404. The end of the return material pipe 404 away from the inclined pipe 403 is inclined downward and connected to the return material bin 103. The return material pipe 401 is installed at the end of the screw conveyor 3.

[0062] In the above technical solution, the excess feed after passing through multiple distribution devices 5 is collected by the return pipe 401 connected to the end of the screw conveyor 3, and then transported to the return silo 103 through the connecting pipe 402, inclined pipe 403 and return pipe 404, thus realizing the automatic recycling of excess feed.

[0063] See Figure 5 and Figure 6 As shown, the material distribution device 5 includes a material conveying pipe 501. A first connecting pipe 502 is provided at the bottom of the material conveying pipe 501. An electrically controlled valve 503 is installed through the first connecting pipe 502. Two side plates 504 are symmetrically arranged on the outer wall of the first connecting pipe 502. An electronic weighing scale 505 for weighing is installed on the side plates 504. A feeder 51 is movably arranged below the first connecting pipe 502. A guide rod 506 is provided at the upper end of the feeder 51. The guide rod 506 passes upward through the side plates 504 and engages with a pressure plate 507. The pressure plate 507 acts on... The electronic weighing instrument 505 and the electrically controlled valve 503 are both electrically connected to the controller. The electronic weighing instrument 505 measures the weight of the feeder 51. When the electrically controlled valve 503 is opened, the feed conveyed by the screw conveyor 3 falls into the feeder 51. As the feed enters, the weight of the feeder 51 increases, and the weight of the feeder 51 is fed back to the controller in real time through the electronic weighing instrument 505. When the preset weight of the controller is reached, the controller controls the electrically controlled valve 503 to close, and the feeding stops. The main water pipe 6 works in conjunction with the feeder 51.

[0064] In the above technical solution, when the feeder 51 is unloaded, the electronic scale 505 counts as 0. As the material enters the feeder 51, the weight of the feeder 51 increases, and the count of the electronic scale 505 also increases. When the set feeding amount of the controller is reached, the electric control valve 503 closes, and the material cannot enter the feeder 51 at this time, thereby accurately controlling the amount of feed fed into the pig pen.

[0065] See Figure 7 and Figure 8As shown, the feeder 51 includes a storage bin 510, a bin cover 511 at the upper end of the storage bin 510, a conical material gathering part 512 at the lower part of the storage bin 510, a discharge pipe 513 at the bottom of the material gathering part 512, a drive motor 514 installed at the lower end of the discharge pipe 513, the output end of the drive motor 514 is inserted into the discharge pipe 513 and then fitted with a spiral blade 515, the spiral blade 515 passes upward through the discharge pipe 513 and the material gathering part 512 and then inserts into the storage bin 510, a discharge nozzle 516 is provided near the lower part of the outer wall of the discharge pipe 513, the feed is discharged into the pigsty through the discharge nozzle 516, and an assembly pipe 517 is provided at the upper end of the bin cover 511, the first connecting pipe 502 is inserted into the assembly pipe 517 and is clearance-fitted with the assembly pipe 517.

[0066] In the above technical solution, the feed that falls into the storage tank 510 is stored. According to the particle size of the feed, after the feed is fed into the storage tank 510, it is observed whether the material will leak out along the material gathering part 512, the unloading pipe 513 and the discharge nozzle 516. If leakage occurs, an electrically controlled valve needs to be installed at the end of the discharge nozzle 516. The electrically controlled valve opens when the drive motor 514 is started and closes when the drive motor 514 is turned off.

[0067] See Figure 3 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an annular water tank 520 is installed at the inner top position of the bucket lid 511. A water distribution pipe 521 connecting the water tank 520 is provided at the top of the bucket lid 511. A first electrically controlled valve 522 connected to the controller is installed on the water distribution pipe 521. A flexible hose 523 is fitted between the water distribution pipe 521 and the main water pipe 6. An annular water distribution ring 524 is provided near the top position on the inner side of the storage bucket 510. A drain hole 525 is provided at the bottom of the water distribution ring 524. A sealing ring 5555 is embedded in the inner wall of the water distribution ring 524, and an annular baffle 526 is provided on the outer wall of the water tank 520. After the water tank 520 is inserted into the water distribution ring 524, it contacts the sealing ring 5555 to form a seal. After the baffle 526 contacts the water distribution ring 524, it limits the downward movement of the water tank 520. A water outlet 527 is provided on the outer wall of the water tank 520 above the baffle 526. The water outlet 527 is inclined towards the inner wall of the storage tank 510.

[0068] In the above technical solution, the top-mounted water tank 520 delivers water to the water distribution ring 524. The water then flows downwards through the drain hole 525 into the feed storage bin, cleaning the bin and delivering any remaining feed to the pigpen. This method, which cleans the feed and supplies the cleaned water to the pigs, increases water utilization and reduces the growth of bacteria in the feed storage bin.

[0069] See Figure 6 and Figure 11 As shown, the inner diameter of the feed pipe 501 is larger than the inner diameter of the screw conveyor 3. An inner pipe 551 is installed inside the feed pipe 501, and the inner diameter of the inner pipe 551 is the same as the inner diameter of the screw conveyor 3. End plates 552 are provided at both ends of the inner pipe 551, and the end plates 552 are fixed to the inner wall of the feed pipe 501. With the support of the end plates 552, a gap is formed between the inner pipe 551 and the feed pipe 501. The first connecting pipe 502 is inserted upwards into the feed pipe 501 and then connects to the inner pipe 551. A stepped groove is provided at the upper part of the inner pipe 551, and a hot air mesh 553 is installed in the stepped groove. The mesh size of 53 is 40-60 mesh. A frame 554 is installed outside the inner tube 551, located on the outer side of the stepped groove. The frame 554 contacts the inner wall of the feed tube 501. A maintenance box 555 is provided at the top of the feed tube 501. The maintenance box 555 is connected to the interior of the feed tube 501 and corresponds to the hot air mesh 553. A cover 556 is detachably installed at the upper end of the maintenance box 555. A hot air blower is installed inside the maintenance box 555. An air inlet slot 557 is provided above the hot air blower on the outer wall of the maintenance box 555. A hanging bracket 558 is installed on the outer side of the maintenance box 555.

[0070] In the above technical solution, after cleaning the storage tank with water from the water tank outlet, the residual moisture is likely to cause mold growth, hence the above technical solution was designed.

[0071] In the above technical solution, after the daily feed feeding is completed, the storage hopper is emptied and rinsed by water from the water tank. After rinsing, the controller controls the electric valve to open. Once opened, the controller controls the hot air blower to operate. The hot air blower sends hot air into the screw conveyor. The temperature of the hot air output from the hot air blower is greater than 75 degrees Celsius. Part of the hot air enters the screw conveyor to achieve hot air sterilization, and part of the hot air enters the storage hopper through the opened electric valve to dry the storage hopper.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
