Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0021] The first embodiment, as shown in Figures 1-5 , the present application provides a kind of water-soluble fertilizer automatic mixing device, including mixing bin 1, the top of mixing bin 1 is equipped with weighing device, weighing device includes the weighing pipe 2 that is communicated with mixing bin 1, weighing pipe 2 is magnetic metal material, support shaft 3 is slid along the axis of weighing pipe 2, two half-round support plates 4 are hinged on support shaft 3, the end of support plate 4 is equipped with permanent magnet 5, when two support plates 4 are in the same plane, two support plates 4 and support shaft 3 can be closed weighing pipe 2 by mutual cooperation, support shaft 3 is driven by driving device.

[0022] In use, the water-soluble fertilizer particles are gradually added into the weighing tube 2, and the weight of the water-soluble fertilizer particles overcomes the attraction of the weighing tube 2 to the support plate 4. When the gradually increasing water-soluble fertilizer particles reach a preset value, the support plate 4 gradually moves away from the inlet end of the weighing tube 2. Finally, the support plate 4 is separated from the weighing tube 2, and the attraction of the permanent magnet 5 to the weighing tube 2 also disappears. At this time, the support plate 4 rotates along the support shaft 3 under the influence of gravity and opens the weighing tube 2, realizing the effect of quantitative addition of water-soluble fertilizer particles. When the discharging is finished, the support shaft 3 is reset by the driving device, and the permanent magnet 5 at the end of the support plate 4 attracts the weighing tube 2, so that the support plate 4 approaches and closes the weighing tube 2. Through simple structure, the maintenance of the device is easier, the maintenance cost and failure rate are reduced, and the time for manual weighing and mixing is reduced, ensuring the stability and consistency of product quality. And by relying on the weight of the material itself and the magnetic force to realize the weighing function, the energy consumption is reduced. The side wall of the mixing bin 1 can be provided with a handle, and the bottom end of the mixing bin 1 can be provided with a universal wheel. The handle and the universal wheel are prior art, and the handle and the universal wheel can facilitate the movement of the mixing bin 1.

[0023] As shown in Figures 3-5 The driving device includes a fixed cylinder 8 clamped on the mixing bin 1, and the weighing tube 2 is clamped in the fixed cylinder 8. The inner side wall of the weighing tube 2 is provided with two symmetrical sliding grooves 9, and the two ends of the support shaft 3 slide along the sliding grooves 9. The outer side wall of the weighing tube 2 is provided with an annular accommodating groove, the side wall of the fixed cylinder 8 is provided with a limiting groove 10, the inner side wall of the limiting groove 10 is provided with a guide groove 11, a gasket 12 slides in the guide groove 11, a bolt 13 is screwed in the gasket 12, a magnet ring 14 is fixed at the small end of the bolt 13, the magnet ring 14 is opposite to the magnetic pole of the end of the support plate 4, the magnet ring 14 can be placed in the accommodating groove, and the bottom end of the sliding groove 9 is provided with a spring 15, and the spring 15 can abut against the end of the support shaft 3. The mixing bin 1 and the fixed cylinder 8 are clamped by the existing clamping method.

[0024] In use, the bolt 13 is loosened to slide the bolt 13 along the limiting groove 10, and the bolt 13 is moved to drive the magnet ring 14 to slide along the accommodating groove, when the magnet ring 14 moves to a suitable distance, the bolt 13 is tightened, the bolt 13 can exert pressure on the magnet ring 14 through the cooperation of the bolt 13 and the gasket 12, the friction between the magnet ring 14 and the fixed cylinder 8 and the weighing tube 2 is increased, so that the magnet ring 14 is fixed, and the volume of the weighing tube 2 can be adjusted through the adjustable magnet ring 14, and the flexibility and applicability of the weighing device are improved. After the discharge is completed, the spring 15 can provide a pushing force for the supporting shaft 3, so that the supporting shaft 3 and the supporting plate 4 can move upward, and the friction of the supporting plate 4 on the supporting shaft 3 is overcome, the operation process is simplified, the working efficiency is improved, and the accurate resetting of the supporting plate 4 and the supporting shaft 3 is ensured. The top end of the weighing tube 2 is fixed with a rotating shaft, and the rotating shaft is fixed with a sealing cover plate. The cover plate can close the weighing tube 2. By setting the cover plate, the weighing device can be closed when in use, thereby effectively preventing foreign matter from falling into the weighing tube 2, ensuring the accuracy of weighing and the purity of the product. The mixing bin 1 and the fixed cylinder 8 are connected by clamping, so that the weighing device can be conveniently disassembled and installed, and maintenance and cleaning are facilitated.

The motor is arranged in the driving bin and penetrates the cylinder body 16 through the output shaft, so that the water-soluble fertilizer particles and water can be quickly mixed. The driving bin not only provides a mounting space for the motor, but also isolates the motor from direct contact with the external environment, reduces the influence of dust, moisture and other adverse factors on the motor, and prolongs the service life of the motor.

The one-way valve is a prior art. The one-way valve has the function of preventing backflow, and ensures that the water-soluble fertilizer cannot flow out along the high-pressure air pipe 18 or cause damage to other equipment.

[0028] The gas flow in the high-pressure gas pipe 18 can accelerate the discharging speed of the liquid, and the gas flow in the high-pressure gas pipe 18 can disturb the water flow in the mixing bin 1, promote the fusion of the water-soluble fertilizer particles and the water flow, and improve the production efficiency. The liquid discharging port 19 at the bottom end of the cylinder body 16 is designed to ensure that the water-soluble fertilizer can be completely discharged clean, and to avoid residue and waste.

Different water-soluble fertilizer particles can be added at the same time through the multiple weighing devices, and each weighing device can independently and accurately weigh a specific amount of water-soluble fertilizer particles, which helps to achieve accurate proportioning between different fertilizers.

[0030] As shown in Figure 1 The side wall of the weighing pipe 2 and the fixed cylinder 8 is provided with a window 20, and the limiting groove 10 is provided with a scale. By setting the window 20 and the scale, the operator can intuitively observe the addition amount of the water-soluble fertilizer particles in the weighing pipe 2, and ensure the accuracy of each addition. By intuitively observing the addition process of the water-soluble fertilizer, the time for repeated operation and debugging is reduced, thereby improving the production efficiency.

[0031] The second embodiment, as shown in Figures 1-3 The driving device includes a pull rod 6, the top end of the pull rod 6 is provided with a hollow baffle 7, the bottom surface of the hollow baffle 7 abuts against the top end of the weighing pipe 2. After the discharging is completed, the support rod is pulled into the weighing pipe 2 through the push-pull rod 6, the weighing pipe 2 is attracted by the permanent magnet 5 at the end of the support plate 4, so that the support plate 4 is close to and closes the weighing pipe 2, and the operator only needs to push and pull the rod 6 to reset the support shaft 3, without complicated operation steps. The hollow baffle 7 has a lighter weight, and by setting the hollow baffle 7, the pressure of the support shaft 3 can be reduced, and the hollow baffle 7 can limit the support rod through the pull rod 6, to prevent the support rod from falling into the mixing bin 1. The other structures of this embodiment are the same as those of embodiment 1.
