Description

Technical Field

[0001] This utility model belongs to the field of fertilizer processing and mixing technology, and more specifically, it relates to a mixing and discharging device for solid fertilizer and liquid fertilizer. Background Technology

[0002] In agricultural production, the mixed application of solid and liquid fertilizers can improve fertilizer efficiency, but existing mixing and discharging devices have obvious defects. Most devices rely on a single stirring structure, which easily leads to liquid-solid stratification, solid agglomeration and encapsulation, and low mixing uniformity; the discharge port is often blocked by wet particles bridging, requiring frequent shutdowns for cleaning.

[0003] Patent CN 218688486 U discloses a mixing and discharging device for solid and liquid fertilizers, including a mixing tank with a feed inlet on one side of the upper part. A mixing assembly is installed inside the tank. An electromagnetic valve is fixedly installed at the bottom of the tank, and a discharge pipe is connected to the lower part of the valve. A first filter screen is inclinedly installed at the lower end of the discharge pipe. A return pipe is located on one side of the mixing tank. An input channel is located on the side of the discharge pipe near the return pipe, at the position of the first filter screen. An output channel is fixedly installed at the upper end of the return pipe near the mixing tank. A return auger rotates inside the return pipe. While this patent solves the mixing problem, it is difficult to fully mix liquid fertilizer with solid fertilizer in a short time when dealing with larger and harder solid fertilizers, requiring a considerable amount of time.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mixing and discharging device for solid fertilizer and liquid fertilizer. Its crushing and mixing mechanism can crush the solid fertilizer, speed up the mixing time, and the crushing and mixing mechanism and the stirring mechanism can discharge the mixed fertilizer without stopping the machine, ensuring that the mixed fertilizer will not settle and maintain a consistent concentration.

[0006] The aforementioned solid fertilizer and liquid fertilizer mixing and discharging device includes a box body, which includes, from top to bottom, a feed inlet, a crushing chamber, and a mixing chamber. A first chamber and a second chamber are respectively installed on both sides of the feed inlet and the crushing chamber. The crushing chamber is rotatably connected to a crushing and mixing mechanism, which includes a crushing frame. Multiple circumferentially arranged scraper plates are fixedly connected to the crushing frame. A liquid outlet pipe is rotatably connected to the middle of the crushing frame and is rotatably connected to the crushing chamber. Multiple nozzles are sealed to the liquid outlet pipe, and the multiple nozzles are respectively facing the bottom and left and right sides of the crushing chamber. A sprocket is fixedly connected to one end of the crushing frame through the box body.

[0007] Preferably, one end of the outlet pipe is sealed and connected to a T-connector, and the other two ends of the T-connector are sealed and connected to the first compartment and the second compartment respectively. A water pump is fixedly connected to one end of the T-connector and the outlet pipe.

[0008] Preferably, a stirring mechanism is rotatably connected inside the stirring chamber. The stirring mechanism includes a stirring frame, on which multiple stirring plates are uniformly fixedly connected. The stirring plates are bent. A shaft is fixedly connected in the middle of the stirring frame. Multiple uniformly arranged stirring rods are fixedly connected on the shaft. Both ends of the shaft are rotatably connected to the housing.

[0009] Preferably, a drive device is fixedly connected to the outer casing of the mixing chamber. The rotating end of the drive device is fixedly connected to a shaft. A sprocket is fixedly connected to the rotating end of the drive device. A chain is meshed and driven on the sprocket, and the chain is meshed and driven on the sprocket.

[0010] Preferably, the feed inlet, crushing chamber, and mixing chamber are interconnected.

[0011] Preferably, an inlet pipe is sealed and connected to the upper part of one side of the first chamber, and the inlet pipe is connected to the first chamber. An outlet pipe is sealed and connected to the bottom of the mixing chamber, and a solenoid valve is installed on the side of the outlet pipe near the mixing chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a crushing and mixing mechanism to cut and pulverize large pieces of solid fertilizer. Liquid fertilizer is then mixed with the solid fertilizer via a nozzle. The nozzle's design, positioned in the center of the crushing frame, ensures more thorough mixing of the liquid and solid fertilizers. The mixture then falls into a mixing mechanism where a mixing plate continuously scrapes the mixing chamber to prevent fertilizer from sticking. A mixing rod continuously stirs and mixes the solid and liquid fertilizers, preventing sedimentation and inconsistent concentrations. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] like Figures 1 to 6 As shown, a mixing and discharging device for solid and liquid fertilizers includes a housing 2. From top to bottom, the housing 2 includes an inlet 203, a crushing chamber 204, and a mixing chamber 206. Solid fertilizer is fed into the inlet 203 for crushing. A first chamber 202 and a second chamber 205 are respectively installed on both sides of the inlet 203 and the crushing chamber 204; the first chamber 202 and the second chamber 205 are used to store liquid fertilizer, facilitating the mixing of liquid and solid fertilizers. Figure 5 As shown, a crushing and mixing mechanism 4 is rotatably connected inside the crushing chamber 204. The crushing and mixing mechanism 4 includes a crushing frame 401, on which multiple circumferentially arranged scraper blades 4011 are fixedly connected. These scraper blades crush the solid fertilizer passing through the crushing chamber 204, and the crushed solid fertilizer is left through the gaps between the scraper blades 4011. A liquid outlet pipe 402 is rotatably connected to the middle of the crushing frame 401. The liquid outlet pipe 402 is rotatably connected to the crushing chamber 204, and multiple nozzles 4021 are sealed to the liquid outlet pipe 402. The nozzles 4021 face the bottom and left and right sides of the crushing chamber 204, respectively. This design allows the nozzles 4021 to fully mix the liquid fertilizer with the solid fertilizer, and the absence of a nozzle at the top of the liquid outlet pipe 402 prevents the liquid fertilizer from spraying out from the feed inlet 203. A sprocket 4012 is fixedly connected to one end of the crushing frame 401 through the housing 2.

[0017] A liquid inlet pipe 201 is sealed and connected to the upper part of one side of the first chamber 202, and the liquid inlet pipe 201 is connected to the first chamber 202. One end of the liquid outlet pipe 402 is sealed and connected to a three-way pipe 3, and the other two ends of the three-way pipe 3 are sealed and connected to the first chamber 202 and the second chamber 205 respectively. After the liquid fertilizer flows in through the liquid inlet pipe 201, the liquid fertilizer in the first chamber 202 will flow through the three-way pipe 3 from the first chamber 202 into the second chamber 205, so that both chambers are filled with liquid fertilizer. A water pump is fixedly connected to one end of the three-way pipe 3 and the liquid outlet pipe 402, which can drive the liquid fertilizer in the first chamber 202 and the second chamber 205 into the crushing chamber 204 to mix evenly with the solid fertilizer.

[0018] like Figure 6 As shown, a mixing mechanism 5 is rotatably connected inside the mixing chamber 206. The mixing mechanism 5 includes a mixing frame 501, on which multiple mixing plates 5011 are evenly fixedly connected. The mixing plates 5011 are bent. A shaft 502 is fixedly connected in the middle of the mixing frame 501, and multiple evenly arranged mixing rods 5021 are fixedly connected to the shaft 502. Both ends of the shaft 502 are rotatably connected to the housing 2. By rotating the drive device 1 in both directions, the fertilizer in the mixing chamber 206 can be mixed evenly.

[0019] A drive device 1 is fixedly connected to the outer casing 2 of the mixing chamber 206. The drive device 1 can rotate forward and backward, making the mixing more uniform and thorough. The rotating end of the drive device 1 is fixedly connected to the shaft 502, and a sprocket 101 is fixedly connected to the rotating end of the drive device 1. A chain 6 is meshed and driven on the sprocket 101, and the chain 6 is meshed and driven by the sprocket 4012. The feed inlet 203, the crushing chamber 204, and the mixing chamber 206 are interconnected. An output pipe 207 is sealed to the bottom of the mixing chamber 206, and a solenoid valve 2071 is installed on the side of the output pipe 207 near the mixing chamber 206.

[0020] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0021] In the working process, the drive device 1 is first started, and solid fertilizer is put into the feed inlet 203. Liquid fertilizer is put into the first chamber 202 and the second chamber 205 through the liquid inlet pipe. The drive device 1 rotates, which drives the stirring mechanism 5 and the crushing and mixing mechanism 4 to rotate respectively. The scraper 4011 on the crushing frame 401 crushes the solid fertilizer. The processed solid fertilizer moves downward and is fully mixed with the liquid fertilizer sprayed by the nozzle. The mixed fertilizer falls into the mixing chamber 206 and is continuously stirred by the stirring plate 5011 and the stirring rod 5021 to prevent sedimentation. When it is needed, the mixture is discharged from the output pipe 207 by opening the solenoid valve 2071 at the bottom of the mixing chamber 206.

[0022] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
