[0005] The scraper arm rod includes a U-shaped section and a bent section. One end of the U-shaped section is fixedly connected to the bottom surface of the gear ring, and the other end of the U-shaped section passes around the lower end of the discharge pipe and is fixedly connected to the bent section arranged in the discharge hopper. A rubber scraper is fixedly connected to the bent section, and the scraper rests on the inner wall of the discharge pipe and the discharge hopper.

[0006] The reduction motor is connected to two time relays, and the two time relays are used for intermittent starting of the reduction motor of the controller.

[0007] The utility model has the following beneficial effects: the scraper arm rod driven by the reduction motor is used to clean the phosphogypsum powder adhering to the inner wall of the lower hopper, thereby preventing the phosphogypsum powder from forming an arch in the lower hopper and ensuring the continuity and stability of the lower hopper's discharge.

[0013] In the figure: a feed hopper 1, a scraper 2, a bending section 3, a reduction motor 4, a support plate 5, a gear 6, a U-shaped section 7, a feed pipe 8, a guide wheel 9, and a gear ring 10. DETAILED DESCRIPTION

[0014] like Figures 1 to 4 As shown, a material breakage prevention device for a phosphogypsum hopper comprises a hopper 1, which is fixedly connected to a feeding pipe 8 via a flange, and two circles of guide wheels 9 are installed on the hopper 1, and the two circles of guide wheels 9 are spaced apart from each other, and each circle of guide wheels 9 is composed of a plurality of guide wheels 9, and each guide wheel 9 is evenly distributed around the axis of the feeding pipe 8, and a gear ring 10 is arranged between the two circles of guide wheels 9, and the two circles of guide wheels 9 are used to limit and guide the gear ring 10, and a T-shaped support plate 5 is installed on the flange, and a reduction motor 4 is installed on the support plate 5, and a gear 6 meshing with the gear ring 10 is arranged on the output shaft of the reduction motor 4, and a scraper arm rod is fixedly connected to the bottom surface of the gear ring 10, and one end of the scraper arm rod is attached to the inner wall of the feeding pipe 8 and the feeding hopper 1.

[0015] When the utility model is used, the reduction motor 4 drives the ring gear 10 to rotate through the gear 6, and the rotating ring gear 10 drives one end of the scraper arm rod to rotate along the discharge pipe 8 and the inner wall of the discharge hopper 1. During the rotation of the scraper arm rod, the phosphogypsum powder adhering to the discharge pipe 8 and the discharge hopper 1 is cleaned to ensure the continuity and stability of the discharge of the discharge hopper 1.

[0016] The scraper arm comprises a U-shaped section 7 and a bending section 3, one end of the U-shaped section 7 is fixedly connected to the bottom surface of the gear ring 10, and the other end of the U-shaped section 7 is fixedly connected to the bending section 3 arranged in the lower hopper 1 after passing the lower end of the discharge pipe 8, and a rubber scraper 2 is fixedly connected to the bending section 3, and the scraper 2 abuts against the inner wall of the discharge pipe 8 and the lower hopper 1. Since the scraper 2 is flexible, it can be more conformed to the inner wall of the discharge pipe 8 and the lower hopper 1, and the phosphogypsum powder can be scraped more cleanly.

[0017] like Figure 3 As shown, the reduction motor 4 is connected to the contacts of the AC contactor KM, the normally closed contacts of the relay KA are connected in series with the AC contactor KM coil, the AC contactor KM coil is connected in parallel with the time relay KT1 coil, the normally open contacts of the time relay KT1 are connected in series with the normally closed contacts of the time relay KT2 and the relay KA coil, the normally open contacts of the relay KA are connected in parallel with the normally open contacts of the time relay KT1, and the coil of the time relay KT2 is connected in parallel with the normally closed contacts of the time relay KT2 and the relay KA coil.

[0018] When the switch QS is closed, the AC contactor KM and the time relay KT1 are energized and the reduction motor M starts to run. At this time, the time relay KT1 starts to count for 10 seconds. When the timing time reaches 10 seconds, the delayed closing contact of KT1 is closed, and the circuit of the relay KA and the time relay KT2 is connected. At this time, the normally closed contact of KA is disconnected, and the reduction motor M stops working. At the same time, KT2 also starts to count for 10 minutes. When the timing time reaches 10 minutes, the delayed opening contact of the time relay KT2 is disconnected, so that the relay KA is de-energized and released. At this time, the normally closed contact of the relay KA is closed, and the AC contactor KM coil circuit is connected again, and the reduction motor M starts to run again. In this way, the scraper arm rod rotates one circle every 10 minutes (assuming that the scraper arm rod rotates one circle in 10 seconds), and there is no need for the scraper arm rod to rotate all the time to scrape the material, which not only saves electricity, but also does not affect the material discharge of the phosphogypsum discharge hopper 1 too much, while reducing the wear of the device and extending the service life of the device.

[0019] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
