Technical Field

[0001] This utility model belongs to the field of animal husbandry technology, specifically relating to a pigsty manure treatment system. Background Technology

[0002] In traditional pig farms, the environmental problems of pigsties have always been a major problem for farmers. Severe accumulation of manure in the pigsties, despite the installation of exhaust fans running day and night, still results in a foul odor and a breeding ground for flies. The main reason is that the manure accumulates in the pens for extended periods without timely removal and fermentation. This situation not only seriously affects the air quality inside the pigsty, harms the health of the pigs, and increases the cost of medication during the breeding process, but also pollutes the surrounding environment.

[0003] Existing technologies mainly rely on manual processing, which suffers from low efficiency, incomplete cleaning, and low automation, failing to meet the high-efficiency and environmentally friendly requirements of modern pig farms.

[0004] Therefore, a new type of pig manure treatment system is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a pigsty manure treatment system that operates automatically without human intervention, in order to improve the shortcomings of existing pigsties.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A pigsty manure treatment system includes a manure pit, a scraper cart installed in the manure pit, and a water and electricity supply system. The manure pit has a V-shaped structure with a U-shaped groove at the bottom. A chain with a stopper disc passes through the U-shaped groove. The scraper cart is installed between the two side walls of the manure pit.

[0025] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to Figures 1-2 and the circuit control principle. A preferred embodiment of the pig manure treatment system shown in this application includes a manure tank 1, a manure scraper and a water and electricity supply system installed in the manure tank 1.

[0027] As shown in the figure, the septic tank 1 has a V-shaped structure. A U-shaped groove 7 is opened at the bottom of the septic tank 1, and a stopper chain is passed through the U-shaped groove 7. The stopper chain is used to transport the fallen feces to the external feces treatment well. A scraper is set between the two side walls of the septic tank 1. The scraper is equipped with circuit control components such as XK1 (forward stroke) and XK2 (rear stroke). The water and electricity supply system is set at one end of the septic tank 1, and is equipped with a position sensing point and a limit switch K1 (starting end). The position sensing point is used to detect the stopping position of the scraper, and works with the limit switch to realize the stopping when the scraper is in position and the triggering of water and electricity replenishment.

[0028] The manure scraper includes a frame body and two pairs of connecting rods on both sides. A spring 5 is connected between the scraper 3 and the connecting rod. A silicone strip is provided at the end of the scraper 3 so that the manure scraper can be tightly attached to the side wall under the tension of the spring 5. When the manure scraper moves back and forth on the side wall of the manure pit 1, the scrapers 3 on both sides can scrape off the pig manure attached to the side wall.

[0029] Specifically, the main frame 4 is equipped with a charging interface, a drive motor (12V DC speed-regulating motor), a battery (12V lead-acid battery), a water tank 8, a water pump (12V DC submersible pump), and a controller (including a power distribution control system, a timer, etc.). The drive motor is electrically connected to the battery. The sides of the scraper are equipped with wheels that are connected to the drive motor. The drive motor outputs power to rotate the wheels, driving the scraper to move back and forth along the length of the septic tank. A spray nozzle 6 is located on the higher side of the scraper 3. The water tank 8 is connected to the spray nozzle 6 via a water pump. During scraping operations, the water continuously flowing from the spray nozzle 6 lubricates the feces, making it easier to fall off, and maintains the cleanliness of the side walls of the septic tank 1.

[0030] The water pump, drive motor, signal transmission module, contactors (KM1-KM6) and switching components are all electrically connected to the controller, forming a complete circuit control system.

[0031] Preferably, the initial end of the manure scraper truck is equipped with a maintenance port and a water spray hole. The manure scraper truck platform is divided into upper and lower layers. The lower layer is a water tank, and the upper layer contains the battery, motor, transmission mechanism, distribution box, and circuit control components (such as contactors, proximity switches, etc.). The top of the manure scraper truck is equipped with a gable roof, and lifting rings are provided at both ends of the roof for easy hoisting and maintenance.

[0032] Specifically, the water tank 8 has a water inlet 13 and a slider, with a float ball 9 at the bottom and a slider sensing point 10 at the top. The water and electricity supply system includes an electromagnetic induction water supply valve BSF and a sensing probe 11 installed at the top of the septic tank 1, and a charging pile installed at the end of the septic tank 1. The electromagnetic induction water supply valve BSF and the sensing probe 11 are respectively set to correspond to the slider sensing point 10 and the water inlet 13, and the charging pile is set to correspond to the charging interface. The electromagnetic induction water supply valve BSF is connected in series with a water level proximity switch SJ, a normally closed contact BSM, and a position locking coil WC.

[0033] Working principle The power supply for the equipment on the manure truck that controls water replenishment and locking at the starting end is 12 volts, while the voltage for other equipment is 220 volts. The disc chain motor is 380V. When the manure truck returns to the starting end and touches the limit switch K1 at the starting end, the normally closed contact of K1 opens, and the disc chain motor stops moving. At the same time, the normally open contact of K1 closes, and the current is transmitted through the normally closed contact BSM of the water level proximity switch SJ to the electromagnetic induction water replenishment valve BSF, causing it to engage and begin replenishing water to water tank 8.

[0034] At the same time, the normally open point BK1 of the electromagnetic induction water supply valve BSF is activated, locking the coil WC in the connected position. After WC is energized and activated, it locks the trolley, preventing it from moving and ensuring that the water supply process proceeds stably. After the normally open point BK2 of the electromagnetic induction water supply valve BSF is activated, the water level proximity switch coil SJ is activated, and SJ is energized to start detecting changes in the water level in the tank.

[0035] When the water level in the tank reaches the preset height, the water level proximity switch coil SJ is triggered, causing the normally closed contact BSM of the water level proximity switch to open, thereby de-energizing the electromagnetic induction water supply valve BSF and stopping water supply; at the same time, the normally open contact BK1 of the electromagnetic induction water supply valve BSF returns to the open state, the position locking coil WC is de-energized and unlocked, and the trolley can start working under the control of the next time period of the time control switch.

[0036] When the time-controlled start and forward travel control are activated, the front proximity switch KM4, the rear proximity switch KM5, and the water level detection proximity switch KM6 are all energized and enter the working state.

[0037] If the water level detection proximity switch KM6 detects that the water tank is full (meeting the operational requirements), its normally open contact becomes a normally closed contact. Power is transmitted to the forward rotation coil of KM2 through the normally closed contact of the front proximity switch KM4 and the normally closed contact of the front limit switch XK1. After KM2 is energized, the low-voltage DC motor starts to rotate forward, driving the manure scraper to move forward. At the same time, the normally open contact of KM2 is energized to achieve self-locking, maintaining the forward movement state.

[0038] After KM2 rotates forward and engages, its normally open contact becomes normally closed, connecting the KM1 water pump coil. After KM1 engages, the submersible pump starts and supplies water to the scraper 3 through the spray nozzle 6, achieving the lubrication and cleaning functions during manure scraping.

[0039] End-of-traverse and return control: When the manure scraper reaches the end of the septic tank, the front proximity switch KM4 detects the arrival signal, and its normally closed contact becomes normally open. The KM2 coil is de-energized, and the drive motor stops moving forward. At the same time, the normally open contact of KM4 becomes normally closed. Power is transmitted to the KM3 coil through the normally closed contact of the rear proximity switch KM5, the normally closed contact of KM4 (which has been switched to closed), and the normally closed contact of the rear limit switch XK2. After KM3 is energized, the low-voltage DC motor starts to reverse, driving the manure scraper back to the starting end.

[0040] After KM3 is energized, its normally open contact engages to achieve self-locking and maintain the reverse travel state; at the same time, the normally open contact of KM3 becomes a normally closed contact, which, when connected, activates the coil of proximity switch KM5, energizing KM5 and putting it into operation to detect the return position in real time.

[0041] Return Stop and Charging Control: When the manure scraper returns to the starting end, the rear proximity switch KM5 (or the rear limit switch XK2) senses the arrival signal, its normally closed contact becomes normally open, the KM3 coil is de-energized, and the drive motor stops reversing; at the same time, the normally open contact of KM3 returns to the open state, the KM1 water pump coil is de-energized, and the submersible pump stops supplying water.

[0042] After the vehicle returns to the starting point, the charging station and the charging interface of the manure scraper automatically connect and make good contact, starting to charge the battery and completing one work cycle. The system then waits for the next start command from the timer switch, repeating the cycle without manual intervention.

[0043] The disc chain linkage control system has no independent start button for the disc chain drive motor. It is controlled by the arrival signal of the manure scraper's proximity switch: When the manure scraper starts moving, the sensor of proximity switch No. 1 at the starting end changes from normally open to normally closed. Current flows through the normally closed contact of the time-delayed disconnect relay, connecting the contactor coil of the disc chain drive motor, and the disc chain starts running. When the manure scraper returns to the starting end, the sensor of the starting end proximity switch changes from normally closed to normally open. The normally closed contact of the time relay is de-energized after a delay (the delay time is adjustable), the contactor coil of the disc chain drive motor is de-energized, and the disc chain stops running.

[0044] After the plug chain contactor is engaged, its auxiliary contact is engaged, and the current flows through the auxiliary contact and the normally closed contact of the water full sensor switch to connect the water supply solenoid valve coil, simultaneously replenishing the water source; after the water is full, the water full sensor switch is activated to open the normally closed contact, and the water supply solenoid valve loses power and stops supplying water.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
