[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] like Figures 1 to 3As shown, a three-chamber dosing device for avoiding blockage includes a box body 1 and a feeding assembly 8. A cover plate 2 is provided on the top surface of the box body 1, and a control cabinet 3 is placed at one end of the top of the box body 1. A water inlet pipe 4 is connected to one side of the box body 1, and the water inlet pipe 4 is L-shaped, and a pressure gauge 5 is placed at one end of the middle of the water inlet pipe 4. The external pump body will transport water through the water inlet pipe 4 to the mixing chamber inside one end of the box body 1. A solenoid valve 6 is placed in the middle of the water inlet pipe 4, and a flow meter 7 is placed at the other end of the middle of the water inlet pipe 4. The pressure gauge 5 and the flow meter are used to measure the pressure of the mixing chamber. 7 is convenient for controlling water inlet, and the feeding assembly 8 is arranged at the other end of the top of the box body 1. The feeding assembly 8 includes a reduction motor 801, an auger shaft 802, a feeding barrel 803, a guide frame 804, a feed hopper 805, a cam 806, a push rod 807, a connecting ring 808 and a spring seat 809. The auger shaft 802 is arranged at one end of the reduction motor 801, and the feeding barrel 803 is sleeved on the outside of one end of the auger shaft 802. The reduction motor 801 drives the auger shaft 802 to rotate, and the material can be gradually pushed into the other end of the feeding barrel 803. The material in the feed hopper 805 is guided by the guide frame 804 and enters the feed barrel 803. A cam 806 is fixed to the outside of the other end of the auger shaft 802, and a push rod 807 is slidably connected to the top of the push rod 807. Connecting ring 808, a spring seat 809 is installed at the bottom of the connecting ring 808, and the spring seat 809 is fixedly connected to the guide frame 804. When the auger shaft 802 rotates, it will also drive the cam 806 to rotate, causing it to squeeze the top rod 807, thereby driving the feed hopper 805 to move upward through the connecting ring 808, and then it will move downward under the action of gravity, and the vibration of the feed hopper 805 will be amplified through the spring seat 809. Therefore, during the feeding process, it can prevent too much material inside the feed hopper 805, causing the lower part to arch and affect the feeding efficiency.

[0025] like Figure 2 、 Figure 4 and Figure 5As shown, a cleaning assembly 9 is provided on the upper part of the feed hopper 805, and the cleaning assembly 9 includes a limiting ring 901 and a handle 902. The upper part of the feed hopper 805 is rotatably connected to the limiting ring 901, and the handle 902 is fixed to the outside of the limiting ring 901. The cleaning assembly 9 also includes a scraper 903 and a reinforcing plate 904. The scraper 903 is fixed to the bottom of the limiting ring 901, and a reinforcing plate 904 is arranged between the scrapers 903. The reinforcing plate 904 is used to reinforce the space between the two scrapers 903 and enhance the stability of the scraper 903 during cleaning. The connecting ring 808 is fixed to the feed hopper 805. The feed hopper 805 is fixedly connected, and the scraper 903 is slidably connected to the feed hopper 805. By driving the limit ring 901 to rotate through the handle 902, the scraper 903 can be used to scrape and clean the inside of the feed hopper 805, thereby improving the convenience of subsequent maintenance and cleaning. A stirring motor 10 is arranged in the middle of the top surface of the box body 1, and a stirring paddle 11 is connected to the bottom of the stirring motor 10. Start the stirring motor 10 to make the stirring paddle 11 mix the material and water. A medicine outlet 12 is arranged in the middle of one side of the box body 1, and an emptying pipe 13 is provided on the other side of the lower part of the box body 1, and an overflow pipe 14 is connected to one side of the upper part of the box body 1.

[0026] In summary, when using the three-chamber dosing device to avoid blockage, first follow the Figures 1 to 5 In the structure shown in the figure, after the material inside the feed hopper 805 enters the feed barrel 803 under the guidance of the guide frame 804, the reduction motor 801 drives the auger shaft 802 to rotate, and the material can be gradually pushed into the other end of the feed barrel 803 and fall into the interior of the box body 1. At the same time, when the auger shaft 802 rotates, it also drives the cam 806 to rotate, causing it to squeeze the top rod 807, thereby driving the feed hopper 805 to move upward through the connecting ring 808, and then it will move downward under the action of gravity, and the vibration of the feed hopper 805 will be amplified by the spring seat 809. Therefore, during the feeding process, it can prevent the material inside the feed hopper 805 from being too much and causing the lower part to arch. Next, the solenoid valve 6 is opened, and the external pump body will transport water through the water inlet pipe 4 to the mixing station inside one end of the box body 1. In the cavity, the pressure gauge 5 and the flow meter 7 are used to conveniently control the water inlet, and then the stirring motor 10 is started to make the stirring paddle 11 mix the material and water. After mixing, it will enter the mixing cavity in the middle through the overflow hole inside the box body 1, and be mixed again. Then it will overflow into the last cavity for storage. Afterwards, after the feeding is completed, when some powder particles are still adhered to the inner wall of the feed hopper 805, it is only necessary to rotate the limit ring 901 by the handle 902 to make the scraper 903 scrape and clean the inside of the feed hopper 805, and use the reinforcement plate 904 to improve the reinforcement between the two scrapers 903. Finally, the mixed liquid medicine will be discharged from the medicine outlet 12, and when the box body 1 needs to be emptied, it is necessary to open the valve on the emptying pipe 13.
