Description

Technical Field

[0001] This invention relates to a transfer system for livestock engineering, specifically an automatic transfer system for pig farm manure. Background Technology

[0002] With the development of the pig farming industry, the large-scale and intensive development of pig farming has led to the generation of a large amount of manure. The on-site transfer of pig farm manure refers to the transfer of manure cleaned from multiple pig houses or multiple manure ditches to the centralized manure treatment area of ​​the pig farm. It is one of the important links in the comprehensive management of pig farm manure "collection-transfer-treatment-utilization".

[0003] Chinese patent document CN105165636A discloses an automated manure treatment system and method for pig farms. The system includes an in-house manure-urine separation mechanical scraper, an external manure automated transport system, a manure fermentation system, and a wastewater purification system. In operation, pig manure, urine, and wastewater from cleaning the pigsty enter the scraping channel of the in-house manure-urine separation mechanical scraper through the slatted floor. The manure is scraped along the bottom of the scraping channel by the mechanical scraper and then into an electric transport cart of the external manure automated transport system. The electric transport cart transports the manure to the fermentation tank of the manure fermentation system for high-temperature rapid fermentation. After fermentation, organic fertilizer is obtained, which can be used in farmland, orchards, etc. Wastewater in the wastewater treatment pond undergoes sedimentation, anaerobic treatment, aerobic treatment, and biological adsorption to meet discharge standards before being discharged.

[0004] Currently, manure transportation includes screw conveyor or belt conveyor modes. For example, Chinese patent document CN110127970A discloses a method and device for comprehensive treatment of pig manure in large-scale pig farms. The method for comprehensive treatment of pig manure in large-scale pig farms includes the following steps: S1. Collecting pig manure from pigsties using mechanical scraping equipment and transporting it to a manure collection tank; S2. Adding the pig manure from the manure collection tank to a fermentation tower using a screw conveyor, first performing anaerobic dry fermentation to produce biogas, and then performing aerobic composting; S3. Storing the biogas produced during the anaerobic dry fermentation process in a gas storage tank, treating the odorous gas produced during the aerobic composting process in a biological filter, transporting the produced organic fertilizer to a maturation workshop for maturation, and pumping the produced biogas slurry and leachate into an anaerobic fermentation reactor to produce biogas; S4. Purifying the biogas obtained in S2 and S3 for use, returning the produced organic fertilizer to the fields, and discharging the produced biogas slurry into an oxidation pond for treatment before irrigating crops. The beneficial effects of this invention are: good treatment effect, simple process conditions, no secondary pollution, and high economic benefits.

[0005] The existing technology has the following shortcomings: In the existing technology, a screw conveyor is used to transport pig manure, but the installation and operation of the screw conveyor are subject to high site restrictions and the transfer distance is limited; in addition, the dryness or looseness of the manure will affect the use of the screw conveyor; and most pig farms are currently built in remote mountainous areas, especially in the hilly areas of the south, where the terrain is usually irregular and the layout of multiple different pig houses in the whole pig farm is not neat, which poses new challenges to the transfer of manure. Summary of the Invention

[0006] To address the limitations of existing technologies that use screw conveyors for manure transfer due to limited transfer distance and high site constraints, this invention provides an automatic manure transfer system for pig farms. The system includes a manure truck, a manure tunnel, a manure ditch inside the pigsty, a scraper installed on the manure ditch, the manure truck, and a control system for the scraper. The manure truck travels along the manure tunnel, and the scraper scrapes solid manure from the manure ditch into the manure truck.

[0007] This includes an outdoor elevator, a tipping unloading machine, and a temporary manure storage tank. The elevator and tipping unloading machine are controlled by a control system. The tipping unloading machine is located on one side of the top of the elevator, and the temporary manure storage tank is located below the tipping unloading machine. After the manure truck enters the elevator, the elevator lifts the manure truck to the top, and then the manure truck enters the tipping unloading machine. The tipping unloading machine causes the manure truck to tip over, and then the manure truck returns along the same route, completing one manure transfer.

[0008] Compared to existing screw conveyors, although other technologies, such as belt conveyors, can achieve long-distance transport, their equipment costs and operating and maintenance expenses are higher, resulting in high transfer costs. Therefore, this solution utilizes a combination of trucks, elevators, and tipping unloaders to achieve long-distance transport of manure. The transport distance and site requirements are unlimited. Furthermore, compared to screw conveyors, the manure trucks in this solution are not affected by the dilution of the manure, are easier to maintain, and have a lower failure rate, thus reducing manure transfer costs. Compared to belt conveyors, this solution significantly reduces equipment costs and operating and maintenance expenses, further lowering manure transfer costs.

[0009] Preferably, the tipping manure unloading machine includes a tiltable mounting frame, on which are provided support rails and fixing rods. The support rails and fixing rods are arranged opposite each other, and the distance between the support rails and fixing rods is equal to the height of the manure truck. In this design, the manure truck is clamped and fixed by the cooperation of the support rails and fixing rods, so that when the mounting frame tilts, the manure truck can also tilt along with it. The manure transported in the manure truck can then be poured into the temporary manure storage tank below, ensuring the normal operation of the subsequent transfer process. The structure is simple.

[0010] Preferably, the tipping manure unloading machine is equipped with fixing rods at both the front and rear ends along the direction of travel of the manure truck, and the distance between the fixing rods at the front and rear ends is less than the length of the manure truck. In this design, the setting of the fixing rods being less than the length of the manure truck ensures the clamping effect on the manure truck, and the structure is simple.

[0011] Preferably, the manure ditch has a stop position, a pause position, and a turning position along its length. The control system controls the scraper to move from the stop position to the pause position and then stop, controlling the manure truck to travel to the manure ditch. The scraper then moves to the turning position and returns to the stop position, where it stops. The control system then controls the manure truck to enter the tipping unloading machine. In this design, the scraper stops at the stop position within the manure ditch when not in operation. After the scraper starts scraping, it stops when it reaches the pause position. The control system then controls the manure truck to travel to the corresponding end of the manure ditch. Once the truck is in position, the scraper restarts. Upon reaching the pause position, it scrapes the solid manure from the manure ditch into the manure truck. The scraper then returns to the stop position. The different stages of the scraping process correspond to different travel positions of the manure truck, ensuring accurate manure entry into the truck and guaranteeing accurate manure transfer.

[0012] Preferably, the system also includes a frame, on which the tipping unloader and temporary septic tank are mounted. The bottom of the temporary septic tank has an openable baffle, and a space for a septic truck to enter is provided below the frame. In this design, the frame facilitates the installation of the tipping unloader and the temporary septic tank, while the openable baffle at the bottom of the temporary septic tank facilitates the transfer of wastewater within the tank, resulting in a simple structure.

[0013] Preferably, the manure ditch has a V-shaped bottom, with a urine drain pipe buried in the bottom. The V-shaped bottom and urine drain pipe in this design enable automatic separation of livestock manure and urine, and the structure is simple.

[0014] The present invention has the following advantages: Compared with the external flat scraper scraping mode, the manure truck in the present invention has no limitation on the conveying distance and the site, and has a low failure rate; compared with the conveyor belt conveying mode, it can greatly reduce equipment costs and operating and maintenance costs.

[0025] The following detailed description illustrates the specific implementation method:

[0026] The reference numerals in the accompanying drawings of the instruction manual include: 1. Livestock shed; 11. Manure truck position control limit switch; 12. Elevator limit switch; 13. Tilting manure unloader limit switch; 2. Manure ditch; 21. Stop position; 22. Pause position; 23. Turning position; 3. Manure tunnel; 4. Manure scraper; 5. Manure truck; 6. Elevator; 7. Frame; 8. Tilting manure unloader; 81. Mounting frame; 82. Support rail; 83. Fixing rod; 9. Temporary manure storage tank; 90. Manure truck.

[0027] The basic implementation examples are as follows: Figures 1-7 As shown: An automatic manure transfer system for pig farms includes a manure truck 5, a manure tunnel 3, a manure ditch 2 inside the livestock shed 1, a manure scraper 4 installed on the manure ditch 2, a control system for the manure scraper 4, an elevator 6 outside the shed, a tipping and unloading manure machine 8, and a temporary manure storage tank 9. Figure 1 As shown, livestock and poultry house 1 includes multiple pig houses.

[0028] The manure truck 5 includes a truck bed and wheels. The truck bed is made of 304 stainless steel, and the wheels are solid rubber wheels with a diameter of 0.4 meters. The manure truck 5 is powered by a 48V battery and communicates with the control system wirelessly. It can also be powered by a 380V sliding contact line.

[0029] The manure truck 5 travels along the manure transport tunnel 3. The scraper 4 scrapes solid manure from the manure ditch 2 into the manure truck 5. The manure ditch 2 has a V-shaped bottom, with a urination pipe buried at the bottom. The manure ditch 2 has a stop position 21, a pause position 22, and a turning position 23 along its length. Figure 3As shown. The control system controls the manure scraper 4 to move from the stop position 21 to the pause position 22 and then stop. It also controls the manure truck 5 to move to the manure ditch 2. Then, it controls the manure scraper 4 to move to the turning position 23 and turn back to the stop position 21 and stop. The control system then controls the manure truck 5 to drive into the tipping unloading machine 8.

[0030] The elevator 6 and the tipping unloader 8 are controlled by a control system. The tipping unloader 8 and the temporary storage tank 9 are installed on the frame 7. The tipping unloader 8 is located on one side of the top of the elevator 6, and the temporary storage tank 9 is located below the tipping unloader 8. The bottom of the temporary storage tank 9 is equipped with an openable baffle. There is an entry space for the manure truck 90 under the frame 7. After the manure truck 5 drives into the elevator 6, the elevator 6 lifts the manure truck 5 to the top, and then the manure truck 5 drives into the tipping unloader 8. The tipping unloader 8 causes the manure truck 5 to tip over, and then the manure truck 5 returns along the same route, completing one manure transfer.

[0031] Specifically, the tipping manure unloading machine 8 includes a tiltable mounting frame 81, on which a support rail 82 and a fixing rod 83 are provided. The support rail 82 and the fixing rod 83 are arranged opposite each other, and the distance between the support rail 82 and the fixing rod 83 is equal to the height of the manure truck 5. The tipping manure unloading machine 8 has fixing rods 83 at both the front and rear ends along the traveling direction of the manure truck 5, and the distance between the fixing rods 83 at the front and rear ends is less than the length of the manure truck 5. Figure 6 As shown. A toothed ring is provided on the outer periphery of the mounting frame 81, and a chain that meshes with the toothed ring is provided on the frame 9. Thus, the movement of the chain will drive the meshing toothed ring to rotate, thereby realizing the tilting of the manure unloading machine.

[0032] The specific implementation process is as follows: When the manure truck 5 is not in operation, it is stopped on the platform of the elevator 6, with the platform of the elevator 6 at the bottom. Figure 1 As shown, manure ditch 2 enables automatic separation of livestock and poultry manure and urine. Urine is discharged into the farm's sewage pipe through the urine drain pipe, while solid manure is scraped to the end of manure ditch 2 outside the shed by the manure scraper 4.

[0033] When not in operation, the manure scraper 4 will stop at stop position 21 within the manure ditch 2. After the manure scraper 4 begins scraping manure, it will stop when it reaches the pause position 22. The control system will then control the manure transport vehicle 5 to travel to the corresponding end of the manure ditch 2. Figure 2 As shown.

[0034] After the manure truck 5 arrives at its destination, the manure scraper 4 starts up again. After reaching the stop position 22 of the manure scraper 4, it scrapes the solid manure in the manure ditch 2 into the manure truck 5. Then the manure scraper 4 returns to the stop position 21, and the control system controls the manure truck 5 to drive towards the elevator 6.

[0035] When the manure truck 5 reaches the elevator 6, the truck stops, and the control system starts the elevator 6 to rise. Once the elevator 6 reaches the position of the tipping unloading machine 8, it stops rising. Figure 4 As shown, the manure truck 5 starts and drives into the tipping manure unloading machine 8, as... Figure 5 As shown.

[0036] After the manure truck 5 enters the tipping unloading machine 8, the truck stops running. The control system starts the tipping unloading machine 8, which rotates the manure truck 5 one revolution, dumping the solid manure inside into the temporary storage tank 9 below. Figure 6 As shown. After the overturning unloading machine 8 returns to its upright position, the manure truck 5 starts and returns along the original route to the next manure ditch 2 to continue transporting the manure from the next manure ditch 2.

[0037] When the temporary septic tank 9 is full, the manure truck 90 can drive under the temporary septic tank 9. The bottom baffle of the temporary septic tank 9 can be opened by a motor to pour the manure into the manure truck 90.

[0038] In the above process, the manure truck 5 is equipped with limit switch blocks. The control system controls the movement position of the manure truck 5 through the limit switches, such as... Figures 8-10 As shown, the manure truck 5 is equipped with a manure truck position control limit switch 11, the elevator 6 is equipped with an elevator limit switch 12, and the tipping manure unloader 8 is equipped with a tipping manure unloader limit switch 13. When the control system controls the manure truck 5 to reach each limit switch position, it will stop moving. After completing the transfer operation at each position, the control system will control the manure truck 5 to move again.
