Description

Technical Field

[0001] This utility model relates to a mixing device, and more particularly to a device that can uniformly mix granular fertilizer into an aqueous solution, belonging to the technical field of granular fertilizer mixing equipment. Background Technology

[0002] Granular fertilizer is a granular, water-soluble compound fertilizer that dissolves completely in water. It contains more nutrients than regular compound fertilizers and has a higher absorption and utilization rate. Granular fertilizer can be applied in various ways, including sprinkler irrigation, drip irrigation, and broadcasting. It needs to be dissolved in water before being sprayed onto the crop roots for absorption. Currently, granular fertilizer is directly added to the water tank, resulting in some granules not completely dissolving. This leads to the fertilizer concentration in the sprayed water not reaching the target level, and residual fertilizer in the tank affects the concentration of granules in the water during subsequent applications. Excessive concentration can adversely affect crops. Therefore, a mixing device is needed to ensure that the granular fertilizer is evenly mixed into the water, thus ensuring the reliability of fertilization operations. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a granular fertilizer dissolving and mixing device that can effectively dissolve granular fertilizer in water, thereby ensuring that the fertilizer concentration in the spray water flow is within a preset range.

An openable cover plate is provided on the top surface of the cylinder. The stirring part is located on the bottom surface of the cylinder. The grinding part is located on the inner wall of the cylinder. The driving mechanism is located at the top of the cylinder and is connected to the grinding part.

[0006] The above-mentioned granular fertilizer dissolving and mixing device includes a stirring part comprising a motor, a connecting shaft, and fan blades; the motor housing is located on the bottom end face of the outer wall of the cylinder; a hole is provided at the center of the bottom end face of the cylinder, and the connecting shaft passes through the center hole of the bottom end face of the cylinder; multiple fan blades are provided at the top end of the outer wall of the connecting shaft.

[0007] The above-mentioned granular fertilizer dissolving and mixing device includes a grinding section comprising a filter screen, a strip frame, a grinding mechanism, and a vertical rod. The strip frame is disposed on the inner wall of the cylinder, and its length direction is parallel to the axis of the cylinder. The opening direction of the strip frame is horizontal. The two sides of the strip frame are a first port and a second port, respectively. The water flow inside the cylinder rotates and moves, and the water flow passes through the first port and the second port of the strip frame in sequence. The filter screen is disposed at the second port of the strip frame. There are multiple grinding mechanisms, which are equidistantly disposed on the inner wall of the strip frame along its length direction. The vertical rod is connected to each grinding mechanism.

[0008] The above-mentioned granular fertilizer dissolving and mixing device includes a compaction mechanism comprising a fixed plate, a pressure plate, and a baffle. The fixed plate is disposed on the inner wall of the strip frame, and one end face of the fixed plate is connected to the filter screen. The pressure plate is located directly above the fixed plate, and the plane of the pressure plate is parallel to the plane of the fixed plate. The side walls of the pressure plate are in contact with the inner walls of the strip frame.

The end of the piston rod of the hydraulic cylinder is connected to the top of the vertical rod.

[0010] This invention uses a stirring section to agitate the water inside the cylinder, causing the fertilizer to rotate and move within the water, accelerating its dissolution during this process. Due to the weight of the fertilizer and the presence of centrifugal force, the fertilizer moves along the inner wall of the cylinder. During this movement, the fertilizer enters the strip frame and is blocked by the filter screen. Then, the undissolved fertilizer is crushed by the crushing mechanism, accelerating its decomposition and dissolution in water. Attached Figure Description

[0015] See Figure 1, 2 and Figure 3 This utility model includes a stirring part, a cylinder 1, a driving mechanism, and a grinding part. The cylinder 1 is mounted on the ground by a support. A water inlet pipe is provided at the top of the side wall of the cylinder 1, and a drain pipe is provided at the bottom of the side wall of the cylinder 1. An openable cover plate is provided on the top surface of the cylinder 1. The mixing process of fertilizer and water is carried out inside the cylinder 1. The openable cover plate is used to add fertilizer into the cylinder. The water inlet pipe on the side wall of the cylinder 1 is used to inject water, and the drain pipe is used to discharge the mixed fertilizer and water mixture. The stirring part is located on the bottom surface of the cylinder 1. The stirring part is used to stir the water, so that the fertilizer rotates with the water, and accelerates the fusion during the rotation. The grinding part is located on the inner wall of the cylinder 1. The driving mechanism is located at the top of the cylinder 1 and is connected to the grinding part.

[0016] The stirring part includes a motor 2, a connecting shaft, and fan blades 3; the housing of the motor 2 is located on the bottom end face of the outer wall of the cylinder 1; a hole is provided in the center of the bottom end face of the cylinder 1, and the connecting shaft passes through the center hole of the bottom end face of the cylinder 1; multiple fan blades 3 are provided at the top of the outer wall of the connecting shaft; the motor 2 drives the connecting shaft to rotate, which in turn drives the water inside the cylinder 1 to rotate, thereby achieving the purpose of accelerating the mixing of the rotating water flow and the fertilizer.

[0017] The grinding section includes a filter screen 4, a strip frame 5, a grinding mechanism, and a vertical rod 6. The strip frame 5 is disposed on the inner wall of the cylinder 1, and the length direction of the strip frame 5 is parallel to the axis of the cylinder 1. The opening direction of the strip frame 5 is horizontal. The two sides of the strip frame 5 are a first port and a second port, respectively. The water flow in the cylinder 1 rotates and moves, and the water flow in the cylinder 1 passes through the first port and the second port of the strip frame 5 in sequence. The filter screen 4 is disposed at the second port of the strip frame 5. During the movement of the fertilizer in the water, it is blocked by the filter screen 4, so that the undissolved fertilizer remains in the strip frame 5. There are multiple grinding mechanisms, and they are equidistantly disposed on the inner wall of the strip frame 5 along the length direction of the strip frame 5. The vertical rod 6 is connected to each grinding mechanism.

[0018] The compaction mechanism includes a fixed plate 7, a pressure plate 8, and a baffle 9. The fixed plate 7 is disposed on the inner wall of the strip frame 5, and one end of its face is connected to the filter screen 4. The pressure plate 8 is located directly above the fixed plate 7, and the plane of the pressure plate 8 is parallel to the plane of the fixed plate 7. The side walls on both sides of the pressure plate 8 are in contact with the inner walls on both sides of the strip frame 5. The baffle 9 is disposed on the end face of the pressure plate 8 away from the filter screen 4, and the baffle 9 is connected to the vertical rod 6. When the pressure plate 8 moves downward, it compacts the fertilizer remaining on the fixed plate 7, accelerating its dissolution in water. The function of the baffle 9 is to ensure that the fertilizer does not escape from the gap between the pressure plate and the fixed plate during the compaction process. The baffle 9 acts as a shield, allowing the fertilizer to leave only through the filter screen 4, while undissolved fertilizer cannot pass through the filter screen 4, thus ensuring the efficiency of fertilizer compaction.

[0019] The driving mechanism includes a hydraulic cylinder 10; the hydraulic cylinder 10 is mounted on the top surface of the cylinder 1 via a bracket; the top surface of the cylinder 1 is provided with a hole, and the vertical rod 6 passes through the hole on the top surface of the cylinder 1, and the end of the piston rod of the hydraulic cylinder 10 is connected to the top of the vertical rod 6; the hydraulic cylinder 10 can drive the vertical rod 6 to rise and fall vertically, thereby driving the pressure plate closer to the fixed plate, thereby crushing the undissolved fertilizer between the pressure plate and the fixed plate, and accelerating the mixing speed of the fertilizer into the water.

[0020] Usage process: Inject the required amount of water into cylinder 1 through the water inlet pipe, then open the top cover of cylinder 1 and pour in the fertilizer; then start motor 2 to rotate the fan blades and stir the water in cylinder 1 to accelerate the mixing of water and fertilizer. During this process, hydraulic cylinder 10 moves periodically, driving pressure plate 8 to move up and down. When pressure plate 8 presses down, it crushes the fertilizer that has entered the strip frame 5. This process is repeated to crush the undissolved fertilizer that has entered the strip frame and accelerate its dissolution. After a period of time, the fertilizer is fully dissolved in the water. Then, turn off the motor and hydraulic cylinder, open the drain pipe to drain the mixed solution. The fertilizer mixing operation is now complete.
