In this utility model, the fixing rods 2 are located at the upper end of the water collection trough 1. At the four corners, the fixing rod 2 is made of a sturdy and durable material to ensure that it can withstand the weight of the filter screen 3 and possible external impacts. The mesh size of the filter screen 3 is smaller than that of the water inlet 6, so the filter screen 3 can intercept impurities larger than the water inlet 6. The limiting cover 5 is connected to the upper end of the fixing rod 2. The main function of the limiting cover 5 is to prevent the filter screen 3 from falling off under external force. The drainage structure is arranged below the water collection tank 1 and is connected to the water inlet 6. The inclined plate 7 is located in the water collection tank 1. Inclined plates 7 are arranged on both sides of the water inlet 6. The rainwater flowing into the water collection tank 1 converges along the inclined plate 7 to the water inlet 6 and is discharged through the water inlet 6. The design of the inclined plate 7 can prevent rainwater from accumulating inside the water collection tank 1.

[0032] When using the filter, the staff should remove the limit cover 5, then remove the filter screen 3 from the water collection tank 1, and clean the impurities on the filter screen 3 to keep it unobstructed.

The upper end and the lower end of the crushing chamber 21 are connected to the water inlet pipe 8 and the extension pipe 9, respectively. The design of the protective plate 19 ensures that the driving gear 17 and the driven gear 18 are not affected by impurities, thereby enhancing the durability of the driving gear 17 and the driven gear 18.

[0036] Several toothed plates 22 are fixedly provided on the opposite side walls of the crushing chamber 21. The toothed plates 22 and the crushing teeth 16 on the same side are staggered and overlap each other. The toothed plates 22 further enhance the crushing effect. They cooperate with the crushing teeth 16 to ensure that the impurities entering the crushing chamber 21 are thoroughly crushed.

[0040] Multiple water collection troughs 1 are set according to the length of the eaves. In order to prevent rain leakage at the junction of the water collection troughs 1, a waterproof pad 26 is fixed at the upper end between adjacent water collection troughs 1. The side wall of the waterproof pad 26 abuts against the fixing frame of the filter screen 3. The waterproof pad 26 is made of asphalt material.

[0041] The limit cover 5 and the upper end of the fixing rod 2 are threaded together.

[0042] The working principle of this utility model is as follows: When in use, the staff determines the number and position of the water collection tank 1 according to the actual length of the eaves. Then, the first fixing part 24 is used to fix the water collection tank 1 at the position below the eaves of the house. Next, the insertion hole 4 on the filter screen 3 is aligned with the fixing rod 2 for installation. Then, the limiting cover 5 is threaded to the upper end of the fixing rod 2 to prevent the filter screen 3 from falling off. Then, the water pipe 8, the crushing box 10, the funnel 23, the extension pipe 9 and the motor 11 are connected in sequence. Finally, the extension pipe 9 is fixed to the house using the second fixing part 25.

[0043] When rainwater drips from the eaves, impurities blown by the wind and falling from the roof are left on the filter screen 3, while the rainwater flows into the collection trough 1. The inclined plate 7 in the collection trough 1 guides the rainwater to converge at the water outlet 6 and flows into the pulverizing box 10 through the water pipe 8. At this time, impurities smaller than the mesh of the filter screen 3 also flow into the pulverizing box 10 with the rainwater. Then, under the combined action of the pulverizing teeth 16 on the first pulverizing roller 14 and the second pulverizing roller 15 and the toothed plate 22 on the side wall, the flowing impurities are completely pulverized. Subsequently, the pulverized impurities and rainwater enter the extension pipe 9 through the funnel 23 and are finally discharged to the ground.
