Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer processing technology, and in particular to a mixing and stirring device for the production of mixed livestock and poultry manure organic fertilizer. Background Technology

[0002] A mixing and stirring device is a device that uses a motor to drive the stirring blades to rotate, so as to uniformly mix and stir various materials. It features high mixing efficiency and good mixing uniformity. Some models can also adjust the speed to adapt to the characteristics of different materials. It is widely used in fertilizer, feed and other production scenarios. It is closely related to the production of mixed manure organic fertilizer for livestock and poultry. This type of organic fertilizer requires mixing livestock and poultry manure with straw, microbial agents and other auxiliary materials in a certain proportion. If the mixing is uneven, it will affect the fermentation effect and fertilizer quality. The mixing and stirring device is the core equipment to ensure the uniformity of raw materials.

[0003] A search revealed a Chinese publication (CN218553917U) disclosing a sludge-to-organic-fertilizer processing and mixing device. The device includes a mixing chamber with a sludge inlet on one side of its top surface. A hollow shaft is rotatably connected to the center of the top surface of the mixing chamber via a bearing. The hollow shaft enters the mixing chamber, and several hollow stirring rods are fixedly connected to its outer surface at an angle. The hollow stirring rods are connected to the hollow shaft, and several through holes are formed on their outer surfaces. This sludge-to-organic-fertilizer processing and mixing device introduces sludge into the mixing chamber through the sludge inlet. A drive assembly rotates the hollow shaft and hollow stirring rods. A conveying assembly, a cutting assembly, and a discharge pipe then evenly distribute livestock manure and straw into the mixing chamber through the hollow shaft, hollow stirring rods, and through the through holes, ensuring thorough and uniform mixing of the sludge, livestock manure, and straw, thus guaranteeing the quality of the subsequently produced organic fertilizer.

[0004] The patent description mentions that "the hollow stirring rod and through hole are evenly inserted into the mixing box, so as to fully and evenly mix the sludge, livestock and poultry manure and straw." After the organic fertilizer material in the conveying pipe flows back, it will block the conveying channel, causing subsequent materials to be unable to be conveyed normally, forcing the production line to stop for cleaning. The cleaning process requires disassembling the pipe and removing the clumps of backflow material, which takes anywhere from tens of minutes to several hours, directly interrupting the continuous production process and seriously slowing down the overall production progress. In response to the above problems, a mixing and stirring device for the production of mixed livestock and poultry manure organic fertilizer is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a mixing and stirring device for the production of mixed livestock and poultry manure organic fertilizer, which solves the problem that some existing mixing and stirring devices for the production of mixed livestock and poultry manure organic fertilizer have difficulty preventing backflow in the conveying pipe.

[0006] To achieve the above objectives, this utility model provides a mixing and stirring device for the production of mixed livestock and poultry manure organic fertilizer, including a base plate, support rods fixedly connected to the four top corners of the base plate, a top plate fixedly connected to the top of the support rods, a water storage tank fixedly connected to the top of the base plate, anti-backflow mechanisms fixedly connected to the left and right sides of the water storage tank, a reinforcing rod fixedly connected to the top of the top plate, a crushing box fixedly connected to the outside of the reinforcing rod, and a disassembly and assembly mechanism fixedly connected to the outside of the crushing box. The anti-backflow mechanism includes a pump body, which is externally and fixedly connected to the left and right sides of the water storage tank. A delivery pipe is fixedly connected to the output end of the pump body. A connecting housing is fixedly connected to the outside of the delivery pipe. A cross-shaped placement plate is fixedly connected to the top inside the connecting housing. A mounting housing is fixedly connected to the bottom end of the cross-shaped placement plate. A sliding rod is slidably connected inside the mounting housing. A return spring is sleeved on the outside of the sliding rod. A sealing component is fixedly connected to the bottom outside of the sliding rod. As a further description of the above technical solution: The sealing assembly includes a sealing plate, the outer side of which is fixedly connected to the outside of the sliding rod, and a sealing ring is fixedly connected to the inner bottom end of the connecting housing. The outer bottom end of the sealing plate is in contact with the outer top end of the sealing ring. As a further description of the above technical solution: One end of the reset spring is fixedly connected to the outside of the mounting housing, and the other end of the reset spring is fixedly connected to the outside of the sealing plate; As a further description of the above technical solution: The disassembly and assembly mechanism includes a support frame, which is fixedly connected to the outside left side of the crushing box. A motor is fixedly connected to the outside of the support frame. A drive rod is fixedly connected to the drive end of the motor. A sleeve rod is fixedly connected to the outside of the drive rod.

[0007] 1. In this utility model, starting the pump body can cause the water in the storage tank to flow through the delivery pipe and squeeze the sealing plate, causing the sliding rod to compress the return spring. The water flow is injected into the mixing tank to mix with the raw materials. When the pump body stops, the spring rebounds and the sealing plate fits the sealing ring to prevent backflow. The water flow is smooth, ensuring mixing efficiency. The backflow prevention design avoids water waste and water tank contamination, and improves the stability and reliability of material mixing.

[0008] 2. In this utility model, the starting motor drives the crushing blade to rotate, which can efficiently crush raw materials. When disassembling and assembling, pull the sliding clamp rod to compress the tension spring so that it is disengaged from the drive rod, and the crushing blade can be removed. When installing, release the clamp rod, and the spring rebounds and locks it in place. The crushing efficiency is high, and disassembly and assembly do not require tools. The operation is simple and convenient, and it is easy to maintain and replace the blade, thus improving the convenience and continuity of raw material crushing operations.

[0012] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0013] Reference Figures 1 to 3 This utility model provides an embodiment of a mixing and stirring device for producing mixed livestock and poultry manure organic fertilizer. The device includes a base plate 1, which serves as the fundamental support component for the entire device, bearing the weight of all equipment. Its anti-slip design ensures the device will not slide or shift during operation. Support rods 2 are fixedly connected to the four corners of the top of the base plate 1. The support rods 2 connect a top plate 3 to the base plate 1, forming a stable frame structure. The square steel pipe design provides sufficient rigidity and load-bearing capacity, and reinforcing ribs further enhance overall stability. A top plate 3 is fixedly connected to the top of the support rods 2. The top plate 3 mainly supports the upper equipment such as the crushing box 7, and the mounting holes precisely position the crushing box. The rounded corners at position 7 improve operational safety and prevent personnel from being injured by collisions. A water storage tank 5 is fixedly connected to the top of the base plate 1. The water storage tank 5 is used to store the water that needs to be added during the stirring process and prevent rust from contaminating the water quality. The level gauge makes it easy to observe the water volume, and the drain valve makes it easy to clean the impurities inside the water tank regularly. Anti-backflow mechanism 4 is fixedly connected to the left and right sides of the outside of the water storage tank 5. A reinforcing rod 6 is fixedly connected to the top of the top plate 3. The reinforcing rod 6 is used to enhance the installation stability of the crushing box 7, offset the radial force generated during the crushing process, and prevent the connection between the crushing box 7 and the top plate 3 from loosening after long-term use. The crushing box 7 is fixedly connected to the outside of the reinforcing rod 6. The crushing box 7 is the main area for crushing manure. Sufficient wall thickness and wear-resistant treatment ensure it can withstand the impact and friction of hard manure blocks. The design of the inlet and outlet 14 facilitates material loading and unloading and control. The crushing box 7 is externally fixedly connected to a disassembly mechanism 8, which includes a support frame 81. The support frame 81 provides stable support for the motor 82 and the crushing blade 89 assembly. The L-shaped structure enhances load-bearing capacity, and the double-fixing method ensures no shaking occurs during high-speed rotation. The support frame 81 is externally fixedly connected to the left side of the crushing box 7, and the motor 82 is externally fixedly connected to the support frame 81. The motor 82 provides power to the crusher blade 89, and sufficient power ensures that it can crush hard manure blocks. The drive end of the motor 82 is fixedly connected to the drive rod 83. The drive rod 83 transmits the power of the motor to the crusher blade 89 assembly. The high-strength material and chrome plating ensure that it can withstand large torque and has good wear resistance. The drive rod 83 is fixedly connected to the outside of the sleeve rod 84. The sleeve rod 84 serves as the mounting carrier for the crusher blade 89. Its hollow design facilitates connection with the drive rod 83 and reduces the overall weight. The distribution of the connection holes ensures that the crusher blade 89 can be evenly arranged. The upper and lower ends of the sleeve rod 84 are slidably connected to the sliding clamp rod 85. The sliding lever 85, through its engagement with the slot on the drive rod 83, enables the rapid connection and separation of the sleeve rod 84 and the drive rod 83. Its tapered design facilitates insertion into the slot, and galvanizing prevents corrosion. The sleeve rod 84 has an internal cavity 86, providing installation space for the limiting plate 87 and tension spring 88. A guide hole ensures the sliding lever 85 can move smoothly along the axial direction, guaranteeing reliable connection. The limiting plate 87 is slidably connected inside the cavity 86. A tension spring 88 is sleeved on the outside of the sliding lever 85, providing continuous tension to ensure it can be tightly engaged in the slot of the drive rod 83, guaranteeing a reliable connection between the sleeve rod 84 and the drive rod 83 and preventing relative slippage during crushing. Multiple crushing blades 89 are fixedly connected to the outside of the sleeve rod 84. These blades are made of manganese steel and are bolted to the sleeve rod 84. The blades are hardened and evenly distributed in a spiral pattern on the surface of the sleeve rod 84. The external rotatable connection of the crushing blades 89 is to the inside of the crushing box 7. The anti-backflow mechanism 4 includes a pump body 48, which is a corrosion-resistant centrifugal pump. The flow rate is designed according to the requirements of the stirring device. The pump casing is made of cast iron with a rubber lining, and the impeller is made of stainless steel. It is fixedly connected to the outlet of the side wall of the water storage tank 5 via a flange. A shock-absorbing pad is installed at the bottom. The pump body 48 is externally fixedly connected to the left and right sides of the water storage tank 5. The output end of the pump body 48 is fixedly connected to a delivery pipe 41, which is a PVC-U reinforced plastic pipe. It is threaded to the output end of the pump body 48 and sealed with Teflon tape. The pipe body is fixed with pipe clamps. On the support rod 2, a large curvature elbow is used at the bend to reduce resistance. The external connection of the conveying pipe 41 is a connecting housing 42, which serves as the mounting carrier for the anti-backflow component. The thickened design enhances the structural strength and can withstand bidirectional water pressure impact. The anti-corrosion coating is suitable for long-term water immersion. The top of the internal part of the connecting housing 42 is fixedly connected to a cross placement plate 43, which provides rigid support for the mounting housing 44. The cross structure ensures support strength while minimizing water flow resistance. High-precision guide holes ensure the axial movement of the sliding rod 45. Chrome plating enhances wear resistance and prevents long-term friction from reducing guiding accuracy. A mounting housing 44 is fixedly connected to the bottom of the cross-shaped placement plate 43, providing precise guidance for the sliding rod 45 and ensuring the movement accuracy of the sealing assembly 47. Mirror polishing reduces sliding resistance, making the sealing response more sensitive. The sliding rod 45 is slidably connected inside the mounting housing 44, transmitting the spring force of the return spring 46 and the water flow pressure, driving the sealing plate 471 to open and close. High-precision machining ensures smooth, jam-free movement. A return spring 46 is sleeved on the outside of the sliding rod 45, providing continuous sealing pressure to the sealing plate 471, maintaining a sealed state when there is no positive water flow. A sealing assembly 47, including the sealing plate 471, is fixedly connected to the bottom of the sliding rod 45. The sealing plate 471 achieves a tight seal through the elastic deformation of the rubber layer, and the composite structure combines rigid support and sealing elasticity. The enlarged diameter design ensures that the entire sealing surface of the sealing ring 472 is covered. The rounded edge avoids scratching the sealing ring 472 and extends the service life of the seal. The sealing plate 471 is externally fixedly connected to the outside of the sliding rod 45, and the sealing ring 472 is fixedly connected to the bottom of the connecting housing 42. The sealing ring 472 provides a sealing reference surface for the sealing plate 471, which is suitable for the complex media of organic fertilizer production. The high-precision sealing surface ensures a tight fit with the sealing plate 471. The bottom of the outer side of the sealing plate 471 contacts the top of the outer side of the sealing ring 472. One end of the return spring 46 is fixedly connected to the outside of the mounting housing 44, and the other end of the return spring 46 is fixedly connected to the outside of the sealing plate 471. Reference Figures 3 to 5The top plate 3 has a fixed internal connection to a mixing tank 13, which is the core container for the mixing reaction of manure and auxiliary materials. Its conical design facilitates material aggregation towards the discharge port 14, reducing residue. Made of stainless steel, it is corrosion-resistant and easy to clean, meeting the hygiene requirements of organic fertilizer production. The mixing tank 13 has a fixed external connection to a mounting frame 9, which provides stable support for the second motor 10. Its triangular structure has good torque resistance and can withstand the reaction force generated during mixing. The bottom of the mounting frame 9 is fixedly connected to the second motor 10, which provides power to the mixing system. Its reduction gear design ensures that the mixing rod 11 receives sufficient torque, suitable for mixing high-viscosity manure mixtures. The second motor 10... The drive end is fixedly connected to a stirring rod 11, which transmits the motor power to the stirring component. The hollow structure reduces weight and inertial force, and the sufficient wall thickness ensures that it will not deform under heavy load. The bearing seat supports and reduces deflection during high-speed rotation, ensuring stirring stability. A cleaning plate 12 is fixedly connected to the outside of the stirring rod 11. The cleaning plate 12 has both stirring and wall cleaning functions: the propeller blades push the material up and down to achieve uniform mixing, and the rubber scraper scrapes off the material adhering to the barrel wall to avoid local solidification and scaling. A discharge port 14 is fixedly connected to the front of the mixing barrel 13. The discharge port 14 is used to discharge the uniformly mixed organic fertilizer material. The tangential design allows the material to flow out naturally by gravity, reducing residue.

[0014] Working principle: By starting the pump body 48, the pump body 48 enters the interior of the delivery pipe 41 through the water storage tank 5, which in turn allows the water flow to squeeze the sealing plate 471. This causes the sealing plate 471 to drive the sliding rod 45 to slide inside the mounting housing 44, which in turn causes the return spring 46 outside the sliding rod 45 to deform. This allows the water flow to enter the mixing tank 13 through the delivery pipe 41 and mix with the raw materials. When the pump body 48 stops starting, the return spring 46 outside the sliding rod 45 rebounds, which allows the sealing plate 471 to fit against the outside of the sealing ring 472, thus preventing the water flow from flowing back into the interior of the water storage tank 5. By starting motor 82, the motor drives drive rod 83 to rotate, which in turn drives sleeve rod 84 to rotate, which in turn drives crusher blade 89 to rotate, thus crushing the raw material. When disassembling or assembling crusher blade 89, by pulling sliding latch rod 85, the sliding latch rod 85 drives limit plate 87 to slide inside cavity 86, which in turn compresses tension spring 88 outside sliding latch rod 85, causing tension spring 88 to deform, thus separating sliding latch rod 85 from the outside of drive rod 83, and allowing crusher blade 89 to be removed from the outside of drive rod 83. When installing crusher blade 89, by releasing sliding latch rod 85, tension spring 88 rebounds, thus locking sliding latch rod 85 with drive rod 83, thus enabling the installation of crusher blade 89.
