[0048] Two supporting beams 40 are provided, and both ends of the rotating shaft 23 are rotatably connected to the supporting beams 40; the supporting beams 40 span across both sides of the waterway 10, and the supporting beams 40 are fixedly arranged on the upper side of the waterway 10; the waterway 10 is provided with an arc surface at least at the position where the gravel salvage device 20 is located, and the arc surface contacts the lower side of the salvage plate 22 of the gravel salvage device 20. That is, when the salvage plate 22 rotates, the salvage plate 22 can salvage the gravel intercepted by the stone filter end plate 21. A gravel outlet 11 is provided on one side of the waterway 10 above the water surface, and the gravel on the salvage plate 22 can slide out of the gravel outlet 11 along the salvage plate 22.

[0049] The rotation driving device is used to drive the rock breaker 20 to rotate along the delayed axis; the rotation driving device can be a reduction motor, and the output end of the reduction motor is directly fixedly connected to the end of the rotating shaft 23 of the rock breaker 20. Alternatively, a driving gear is provided at the end of the reduction motor, and a driven gear is provided at the end of the rotating shaft 23 of the rock breaker 20, and the driven gear meshes with the driving gear; or it can be a belt drive, and pulleys are provided at the ends of the reduction motor and the ends of the rotating shaft 23 of the rock breaker 20, and the belt is set outside the two pulleys.

[0053] Furthermore, a downward protrusion is provided on the lower side of the shoulder 62; the waterway 10 is provided with a groove for accommodating the protrusion; the protrusion and the groove are embedded and matched, so that the shoulder 62 can be fixed.

[0054] Furthermore, guardrails are provided on both sides of the slide 30, and one end of the slide 30 is connected to the gravel outlet 11; the gravel coming out of the gravel outlet 11 can slide down along the slide 30, and the lower end of the slide 30 can collect the gravel.

[0055] Embodiment 2

[0056] See also Figures 4 to 6Since the crushed stones are irregular, one end of the conical crushed stones is stuck in the water tank 211, and the other end cannot pass through the water tank 211 and is stuck, so the water outlet of the direct filter stone end plate 21 is not smooth. To solve this problem, an improvement is made.

[0057] The difference between the second embodiment and the first embodiment is that it further includes an anti-jamming device 90 and a linear drive module 100;

[0058] The anti-stuck device 90 specifically includes a cleaning block 91, a connecting rod 92, a connecting head 93, and a sliding sleeve 94; wherein the cleaning block 91 is slidably arranged in the water trough 211; the connecting head 93 is inserted into the outer side of the rotating shaft 23, and the connecting head 93 is on the side of the filter stone end plate 21 away from the salvage plate 22; the two ends of the connecting rod 92 are respectively pivotally connected to the connecting head 93 and the two ends of the cleaning block 91; that is, in the process of pushing the connecting head 93, the cleaning block 91 slides in the water trough 211, and squeezes the stuck gravel out of the water trough 211, and then almost all of them are thrown out from the gravel outlet 11.

[0059] The linear drive module 100 is used to reciprocate and push the connector 93; the linear drive module 100 includes a sliding sleeve 94, a driving member 110, a slide plate 120, a slide 121, and a pushing plate 130; the sliding sleeve 94 is slidably inserted into the outer side of the rotating shaft 23, the sliding sleeve 94 is in the hole of the connecting head 93, and the connecting head 93 and the sliding sleeve 94 are directly connected through a bearing; the driving member 110 is a linear reciprocating driving member, which can be an electric cylinder, a hydraulic cylinder or a pneumatic cylinder; the pushing plate 130 is fixedly connected to the sliding sleeve 94; the outer wall of the driving member 110 is fixedly arranged, and the driving component of the driving member 110 is fixedly connected to the pushing plate 130, and the linear extension and contraction of the driving member 110 can make the clearing block 91 slide in the stone filter end plate 21, thereby completing the action of clearing the crushed stones stuck in the stone filter end plate 21.

[0060] Furthermore, in order to make the push plate 130 move more smoothly, a fixed slide plate 120 is set on both sides of the waterway 10, and the slide plate 120 has a slide groove 121 along the axis of the rotating shaft 23; the push plate 130 is provided with a protruding slider, and the slider is slidably set in the slide groove 121.

[0061] Further, the water pressure sensor 200 is disposed between the floating object blocking box 60 and the gravel salvage device 20, and the water pressure sensor 200 is below the water surface;

[0062] When too much gravel is stuck in the water channel 211 of the stone filter end plate 21, the water flow rate of the stone filter end plate 21 becomes smaller, the water where the water pressure sensor 200 is located accumulates and the water level rises; the water pressure sensor 200 can monitor the water pressure in real time.

[0063] The controller is used to receive the signal from the water pressure sensor 200; and the controller can control the sliding of the connector 93 through the signal; thereby starting the work of clearing the stuck gravel.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
