Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a waste crushing device for water conservancy and hydropower. Background Technology

[0002] In the operation of water conservancy and hydropower projects, ensuring smooth water flow and normal equipment operation is crucial. Various pollutants in the water, such as branches, aquatic plants, and domestic waste, can enter the water conservancy and hydropower facilities with the water flow, posing a serious threat to the safe and stable operation of the project. A search revealed a Chinese patent with authorization number CN219401624U, which discloses an underwater pollutant crushing device. The device includes a base, a crushing chamber connected above the base, a feed inlet on the top of the crushing chamber, drive motors installed at both ends on one side of the crushing chamber, and rotating rollers connected to one side of the drive motors. Crushing blades are installed on the outer wall of the rotating rollers. Lifting hydraulic cylinders are connected to both sides above the extrusion plate. A receiving box is located below the extrusion plate, and a filter screen is installed at the bottom of the receiving box. Compared with existing devices, this underwater waste crushing device allows materials to slide down from both sides of the extrusion plate via a guide ramp. The lifting hydraulic cylinder can drive the extrusion plate to move vertically, thereby driving the extrusion plate downward to cooperate with the bottom of the collection box, squeezing out the water in the material. The squeezed water can flow through the filter screen to the bottom of the crushing box, so that no worker assistance is required during the separation and collection process, making it more convenient and efficient.

[0003] The underwater waste crushing device mentioned in the above patent has the following shortcomings: after crushing and squeezing out the waste, the crushed waste needs to be manually discharged, which requires the staff to come into contact with the device. The whole process is unsanitary and inconvenient to use. Therefore, a waste crushing device for water conservancy and hydropower has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste pulverizing device for water conservancy and hydropower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Then, the bottom plate moves, automatically discharging the waste, and the device resets to continue working. The entire process requires no manual contact with the device, reducing labor intensity and effectively solving the problem of manual operation mentioned in the background technology. This achieves a high degree of automation, avoiding direct contact between humans and the moving parts of the equipment, ensuring the hygiene of the staff, reducing labor input, and lowering labor costs.

[0014] 2. By setting up the water guide ramp and water guide channel, the residual sewage will not flow randomly after being discharged. The collection device can be placed at the bottom of the water guide ramp as needed. Attached Figure Description

Triangular grooves 408 are provided on the top outer side of both side plates 406 at the vertical position at the bottom of the irregular holes 407.

[0024] In this utility model, a pressing mechanism 5 is provided at the top of the side of the outer wall of the crushing box 1 away from the L-shaped bracket 4. The pressing mechanism 5 includes a fixing block 501 fixedly connected to the outer wall of the crushing box 1. A second electric push rod 502 is fixedly connected to the bottom of the fixing block 501, and a U-shaped plate 503 is fixedly connected to the bottom of the second electric push rod 502.

[0025] In this utility model, the pressing mechanism 5 also includes guide rods 506 that are slidably sleeved on the bottom of both ends of the U-shaped plate 503 near the crushing box 1. Both ends of the bottom of the U-shaped plate 503 are provided with round holes that are adapted to the guide rods 506. Limiting blocks are fixedly connected to the ends of the two guide rods 506 that are far apart from each other. Fixing rings 507 are fixedly sleeved on the middle of the inner side of the two guide rods 506.

The two guide rods 506 are adapted to the irregular hole 407 and the triangular groove 408. By setting up the pressing mechanism 5, the crushed dirt inside the rectangular frame 402 is squeezed and then automatically unloaded.

[0026] In this utility model, a feed inlet is provided at the top of the crushing box 1, and inclined plates are provided on both sides of the feed inlet of the crushing box 1. Two rotating rods 3 are rotatably connected between the two ends of the top of the crushing box 1. Crushing rollers 302 are fixedly sleeved on the circumferential surface of the two rotating rods 3 inside the crushing box 1. The crushing of the waste is achieved by setting the two crushing rollers 302.

[0027] In this utility model, one end of each of the two rotating rods 3 passes through the crushing box 1 and is fixedly connected to a gear 301, and the two gears 301 mesh with each other. The outer wall of the crushing box 1 is provided with a round hole that matches the rotating rod 3.

[0028] Working principle: When in use, the device feeds waste collected from the water into the crushing box 1 through the top. Driven by the motor 303, the two crushing rollers 302 pulverize the waste. The pulverized waste falls into the rectangular frame 402 at the bottom. Under the action of the bottom plate 403 and the water guide trough 404, residual wastewater is discharged through the water guide trough 404 and the inclined water guide plate 201. Wastewater can be collected as needed and observed through the observation window 101. See, when the rectangular frame 402 is relatively full of dirt, the crushing operation can be stopped, and the first electric push rod 401 can be activated, causing the rectangular frame 402, along with the base plate 403, to move closer to the bottom of the pressing mechanism 5. When the rectangular frame 402 is at the bottom of the pressing plate 505 of the pressing mechanism 5, the second electric push rod 502 can be activated to extend, causing the pressing plate 505 to squeeze the dirt inside the rectangular frame 402, so that the remaining sewage is discharged through the water guide channel 404 and the water guide inclined plate 201. At the same time, the pressing plate 505... When the pressure plate 505 descends, the two guide rods 506 will contact the adjacent triangular groove 408, causing the side plate 406 to retract and compress the second spring 508. When the side plate 406 slides to the bottom of the irregular hole 407, under the action of the second spring 508, the guide rods 506 contact the irregular hole 407. As the second electric push rod 502 retracts, the guide rods 506 slide in the vertical hole of the irregular hole 407. When the pressure plate 505 leaves the rectangular frame 402, the guide rods 506... Sliding into the inclined hole of the irregular hole 407, the water guide 404 moves along with the vertical plate 405 and the side plate 406, compressing the first spring 410 until the bottom of the bottom plate 403 is far away from the rectangular frame 402. At this time, the dirt inside the rectangular frame 402 falls off under the action of gravity. When the guide rod 506 moves away from the irregular hole 407, the bottom plate 403 returns to its original position under the action of the first spring 410, and the first electric push rod 401 retracts, so that the rectangular frame 402 returns to the bottom of the crushing box 1 for collection again.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
