The rice fields provide food for the fish and the fish provide organic fertilizer for the rice fields, thereby improving both ecological and economic benefits.

[0003] In the production process of liquid pesticides, a variety of raw materials need to be put into a mixing box, then water is added, and then they are mixed and stirred. After the mixing is completed, they need to be filtered to reduce the residual residue. However, the existing filtering equipment has poor filtering effect, resulting in a lot of liquid residue.

[0004] After searching, a Chinese utility model with patent publication number CN214102836U discloses a fish-rice symbiotic circulation breeding device, which includes: a circulation system and a fish-rice symbiotic area.

[0016] Furthermore, a spring sheet is fixedly connected to an inner wall of one side of the trapezoidal portion, and an impact ball is fixedly connected to one end of the spring sheet, and the impact ball is located on the rotation radius of the ball rod.

[0017] After adopting the above structure, the present invention has the following advantages compared with the prior art:

[0018] In the present invention, by setting up the rice trough and the fish trough, the breeder can place the fish and the rice in the fish trough and the rice trough respectively, which can effectively prevent the fish from damaging the rice root system when the fish and rice are mixed, and also prevent the fish from dying due to the excessive density of rice and not being able to obtain sufficient oxygen. In this model, the fish trough is set in the middle of the two groups of rice troughs, which not only realizes layered breeding, but also the staggered distribution can effectively prevent the fish trough from blocking the light during the growth of rice, resulting in insufficient light, thereby ensuring the growth quality of rice.

[0019] In the present invention, by means of the drive assembly, the lifting assembly and the dirt removal assembly, the farmer can start the second motor regularly, and the second motor can drive the bidirectional screw to rotate. During the rotation of the bidirectional screw, the threaded sleeve engaged on the outer wall thereof can be made to move horizontally. The horizontal movement of the threaded sleeve can effectively drive the scraper arranged below it to gather the feces deposited on the bottom of the fish tank to the middle, so that the fish feces can fall into the bottom of the trapezoidal part, thereby facilitating the farmer to subsequently transport the feces to the inside of the rice tank for fertilizing the rice, thereby realizing waste utilization of the feces.

[0020] During the horizontal movement of the scraper, the sliders fixedly connected to the outer walls on both sides of the scraper will slide inside the horizontal chute and the arc chute. When the two sets of scrapers move towards each other, the slider will always move inside the horizontal chute so as to gather the feces deposited at the bottom of the fish tank. During the sliding of the slider along the horizontal chute, the slider will apply horizontal thrust to both the first block and the second block. At this time, the first block will rotate upward when it is thrust, and the second block will rotate clockwise when it is thrust until it is completely located inside the placement groove. At this time, the slider can stably slide inside the horizontal chute Without obstruction, when the two groups of scrapers move apart, when the slider slides to the first stopper and the second stopper inside the horizontal slide groove, the slider will slide along the arc slide groove due to the obstruction of the first stopper and the second stopper. At this time, the scraper will move upward and separate from the bottom of the fish tank, which can effectively prevent the scraper from scraping the fish feces to the two sides of the fish tank again to form accumulation during the resetting process. When the slider has completed the path along the arc slide groove, the slider will fall back into the horizontal slide groove again, and the scraper will contact the bottom of the fish tank again to perform the cyclic fish feces gathering work, and no fish feces will remain.

[0021] In the present invention, by providing a first motor, a rotating column, a stirring plate, a ball rod, an impact ball and a mixing tank, when a certain amount of fish feces is accumulated at the bottom of the trapezoidal part, a staff member starts the first motor, and the rotating column can be driven to rotate by the first motor. During the rotation of the rotating column, the stirring plate and the ball rod can be driven to rotate together. The stirring plate can scrape up the fish feces deposited at the bottom of the trapezoidal part, and the rotation of the ball rod can fully dissolve the scraped fish feces in water. An impact ball is provided on one side of the trapezoidal part, and the impact ball is located on the rotation radius of the ball rod. Therefore, during the rotation of the ball rod, the impact ball will collide with the impact ball to generate sound waves to intimidate the surrounding fish, thereby avoiding damage to the fish during the rotation of the ball rod. At the same time, fish are more afraid of black, so a black cloth is bonded to the outer wall of one side of the stirring plate, and a black paint is sprayed on the circumferential outer wall of the ball rod, which can further deepen the intimidation effect on the fish.

[0022] After the fish manure and water are fully mixed, the second pump body is started. The fish manure water at the bottom of the trapezoidal part can be pumped into the mixing tank through the second pump body. The pumped manure water will collide with the dispersion plate, thereby further increasing the solubility of fish manure in water, which is not only beneficial to the absorption of rice seedlings, but also avoids clogging of the pipeline.

[0023] In the present invention, by providing a second pump body, a mixing tank, a feed pipe, a water storage tank, a water distribution tank and a water distribution pipe, the manure water mixed in the mixing tank will enter the water distribution pipe through the feed pipe, and at the same time the water supply pipe is located inside the water storage tank, and the water supply pipe is located on one side of the water storage tank and has a water supply hole, so the manure water will be sprayed onto the inner wall of the water storage tank and flow evenly into the rice trough along the water distribution tank, and the direct spraying of manure water can effectively avoid the damage to the rice seedlings caused by the long-term use of the rice seedlings.

[0024] In the present invention, by providing an oxygenation component, the first pump body is started while the farmer introduces manure water into the rice trough, and the clean water in the rice trough can be pumped into the water distribution tank through the joint action of the first pump body and the pumping pipe. At this time, the clean water pumped into the water distribution tank will flow out along the water distribution trough. Since the water distribution tank and the fish trough have a certain height, some oxygen will be dissolved in the process of the clean water falling, thereby achieving the effect of increasing oxygen in the fish trough, and there will be some insects in the clean water pumped into the rice trough, which can provide certain food for the fish, thereby ensuring that the fish can grow rapidly.

One side of the scraper 20 is provided with through holes distributed at equal distances. The farmer can start the second motor 22 regularly, and the bidirectional screw rod 26 can be driven to rotate by the second motor 22. During the rotation of the bidirectional screw rod 26, the threaded sleeve 28 engaged on its outer wall can be made to move horizontally. The horizontal movement of the threaded sleeve 28 can effectively drive the scraper 20 arranged below it to gather the feces deposited at the bottom of the fish tank 4 to the middle, so that the fish feces can be concentrated and fall into the bottom of the trapezoidal portion 8, so that the farmer can transport the feces to the inside of the rice trough 1 to fertilize the rice later, thereby realizing the waste utilization of feces.

[0042] The lifting assembly includes a horizontal slide 38 and an arcuate slide 37 provided on the inner walls on both sides of the fish tank 4. The horizontal slide 38 is connected to the arcuate slide 37. The outer walls on both sides of the scraper 20 are fixedly connected with sliders.

Since the water supply pipe 47 is located inside the water storage grooves 46 and a water supply hole is provided on one side of the water storage grooves 46, the manure water will be sprayed onto the inner wall of the water storage grooves 46 and flow evenly into the rice trough 1 along the water distribution grooves 24. In this process, the direct spraying of manure water can effectively avoid the damage to the rice seedlings caused by the long-term damage caused by the direct spraying of manure water.

[0044] The oxygenation component includes a water distribution tank 14 fixedly connected to the outer wall of the top of the fixed frame 23. The inner walls on both sides of the water distribution tank 14 are provided with water distribution troughs 13.

At the same time, fish are more afraid of black, so black cloth is bonded to the outer wall of one side of the stirring plate and black paint is sprayed on the circumferential outer wall of the ball rod 16, which can further deepen the intimidation effect on fish.

[0049] In summary, with the help of the above technical scheme of the present invention: the breeders can respectively arrange the fish and rice in the fish trough 4 and the rice trough 1, which can effectively prevent the fish from damaging the rice root system when the fish and rice are mixed, and also prevent the fish from dying due to the excessive density of rice. In the present model, the fish trough 4 is arranged in the middle of the two groups of rice troughs 1, which not only realizes layered breeding, but also the staggered distribution can effectively prevent the fish trough 4 from blocking the light during the growth of rice, resulting in insufficient light, thereby ensuring the growth quality of rice. The breeders can regularly start the second motor 22, which can drive the bidirectional screw rod 26 to rotate. During the rotation of the bidirectional screw rod 26, the second motor 22 can drive the bidirectional screw rod 26 to rotate. During the horizontal movement of the scraper 20, the sliders fixedly connected to the outer walls of the scraper 20 will slide inside the horizontal chute 38 and the arc chute 37. When the two groups of scrapers 20 move toward each other, the sliders will always move inside the horizontal chute 38, so that the feces deposited at the bottom of the fish trough 4 can be gathered. When the sliders move along the horizontal chute 38, the sliders will slide inside the horizontal chute 38 and the arc chute 37. When the two groups of scrapers 20 move toward each other, the sliders will always move inside the horizontal chute 38, so that the feces deposited at the bottom of the fish trough 4 can be gathered. During the sliding process, the slider will apply a horizontal thrust to both the first stopper 39 and the second stopper 40. At this time, the first stopper 39 will rotate upward when the thrust is applied, and the second stopper 40 will rotate clockwise when the thrust is applied until it is completely located inside the placement groove 41. At this time, the slider can stably slide inside the horizontal slide groove 38 without obstruction. When the two groups of scrapers 20 make a separation movement, when the slider slides inside the horizontal slide groove 38 to the first stopper 39 and the second stopper 40, the slider will slide along the arc-shaped slide groove 37 because it is blocked by the first stopper 39 and the second stopper 40. At this time, the scraper 20 will make an upward movement and disengage from the bottom of the fish tank 4, which can effectively prevent the scraper 20 from scraping fish feces to the fish tank 4 again during the resetting process. The fish droppings are accumulated on both sides of the trapezoidal portion 8. When the slider has completed the path along the arc chute 37, the slider will fall back into the horizontal chute 38 again, and the scraper 20 will contact the bottom of the fish tank 4 again to perform the cyclic fish droppings gathering work, and there will be no fish droppings residue. When a certain amount of fish droppings are accumulated at the bottom of the trapezoidal portion 8, the staff will start the first motor 7, and the first motor 7 can drive the rotating column 15 to rotate. During the rotation of the rotating column 15, the stirring plate and the ball rod 16 can be driven to rotate together. The stirring plate can scrape up the fish droppings deposited at the bottom of the trapezoidal portion 8, and the rotation of the ball rod 16 can fully dissolve the scraped fish droppings in the water. An impact ball 17 is provided on one side of the trapezoidal portion 8, and the impact ball 17 is located on the rotation radius of the ball rod 16.Therefore, during the rotation of the ball rod 16, it will collide with the impact ball 17 to generate sound waves to intimidate the surrounding fish, thereby avoiding damage to the fish during the rotation of the ball rod 16. At the same time, fish are more afraid of black, so black cloth is glued to the outer wall of one side of the stirring plate, and the circumferential outer wall of the ball rod 16 is sprayed with black paint, which can further deepen the intimidation effect on fish. The fish feces water at the bottom of the trapezoidal part 8 can be pumped into the mixing tank 30 through the second pump body 29. The pumped feces water will collide with the dispersion plate 33, thereby further improving the solubility of fish feces in water, which is not only beneficial to the absorption of rice seedlings, but also avoids clogging of the pipeline. Since the water supply pipe 47 is located in the water storage tank 46, and the water supply pipe 47 is located on one side of the water storage tank 46 with a water supply hole, the feces water will be sprayed to The inner wall of the water sump 46 flows evenly into the rice trough 1 along the water distribution trough 24. In the process, the direct spraying of manure water can effectively avoid the damage to the rice seedlings caused by the long-term spraying. When the breeder introduces the manure water into the rice trough 1, the first pump body 11 is started. Through the joint action of the first pump body 11 and the pumping pipe 2, the clean water in the rice trough 1 can be pumped into the water distribution tank 14. At this time, the clean water pumped into the water distribution tank 14 will flow out along the water distribution trough 13. Since the water distribution tank 14 and the fish trough 4 have a certain height, some oxygen will be dissolved in the process of the clean water falling, so as to achieve the effect of increasing oxygen inside the fish trough 4. In addition, there will be some insects in the clean water pumped from the rice trough 1, which can provide certain food for the fish and ensure that the fish can grow quickly.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

When the two groups of scrapers (20) move toward each other, the sliders will always move inside the horizontal slide groove (38) so as to gather the feces deposited at the bottom of the fish tank (4). During the sliding of the slider along the horizontal slide groove (38), the slider will apply a horizontal thrust to both the first stopper (39) and the second stopper (40). At this time, the first stopper (39) will rotate upward when the thrust is applied, and the second stopper (40) will rotate clockwise when the thrust is applied until it is completely located inside the placement groove (41). At this time, the slider can stably slide inside the horizontal slide groove (38) without moving. When the two groups of scrapers (20) move away from each other, the slider slides to the first stopper (39) and the second stopper (40) in the horizontal chute (38). Since the slider is blocked by the first stopper (39) and the second stopper (40), it will slide along the arc chute (37). At this time, the scraper (20) will move upward and separate from the bottom of the fish trough (4). This can effectively prevent the scraper (20) from scraping the fish feces to the two sides of the fish trough (4) again during the resetting process to form accumulation. When the slider has finished walking along the path of the arc chute (37), the slider will fall back into the horizontal chute (38) again, and the scraper (20) will contact the bottom of the fish trough (4) again to perform the cyclic fish feces gathering work, and no fish feces will remain.
