Detailed Implementation

[0029] To make the objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments.

[0030] like Figure 1 As shown, the present invention provides a power insulator crushing device, including a jaw crusher 1, a controller, and a frame 3. The jaw crusher 1 includes a feed inlet, a discharge outlet, and a discharge regulator; as shown... Figure 4As shown, the insulator includes a porcelain body 21 and a central iron accessory 22; the size of the iron accessory 22 is different for different types of insulators to be broken; according to the diameter size of the iron accessory 22, the controller adjusts the size of the discharge port through the discharge adjusting device, so that the movable jaw tooth plate and the fixed jaw tooth plate only break the porcelain body 21 around the iron accessory 22.

[0031] As shown in Figure 1 , Figure 3 , the rack 3 is provided with a feeding channel 31, and two slide rods 32 are connected to the inner wall of the feeding channel 31 in parallel and at intervals, the slide rods 32 are inclined from top to bottom to the feeding port; the head of the iron accessory 22 is located between the two slide rods 32 downward; the porcelain body 21 slides along the two slide rods 32, and the insulator falls vertically into the feeding port. Such a structure is beneficial to the insulator to maintain a preset posture into the breaking chamber. Since the outer diameter of the porcelain body 21 is much larger than the outer diameter of the iron accessory 22, the movable jaw tooth plate and the fixed jaw tooth plate first break the porcelain body 21; then, the iron accessory 22 is affected by gravity, the head of the iron accessory 22 is downward and moves downward, and is discharged from the discharge port; effectively avoiding the insulator to be randomly accumulated in the breaking chamber, causing the movable jaw tooth plate and the fixed jaw tooth plate to squeeze and collide with the iron accessory 22, causing damage and excessive breaking vibration. Since the insulator enters the breaking chamber regularly, it avoids material accumulation in the breaking chamber and avoids the return of the material during the breaking process, ensuring smooth discharge of the material.

[0032] As shown in Figure 4 , an electromagnet 4 is arranged below the slide rod 32, and the electromagnet 4 is arranged at least two intervals along the slide rod 32; the electromagnet 4 is electrically connected with the breaking controller, and the plurality of electromagnets 4 are alternately powered on or powered off, so that the iron accessory 22 is separated from the electromagnet 4 to slide downward or is adsorbed to stop. By controlling the sliding of the insulator on the slide rod 32 through the electromagnet 4, the waste insulator entering the breaking chamber is controlled, and the material accumulation in the breaking chamber is effectively avoided.

[0033] A size measuring module 5 is also arranged below the slide rod 32, the iron accessory 22 passes through the measuring head of the size measuring module 5, and the size measuring module 5 feeds back the size of the iron accessory 22 measured to the controller. The size measuring module 5 is electrically connected with the controller, and the size measuring module 5 adopts existing non-contact measurement technology; the controller automatically adjusts the size of the discharge port according to the actual size of the iron accessory 22, which saves the work of manually determining the size of the discharge port.

[0034] As shown in Figure 4 , the insulator is in a plurality of series, and the insulator at the top slides along the slide rod 32. According to the series of the insulator, the size of the feeding channel 31 of the rack 3 is set, so that the insulator is hung in series in the feeding channel 31, without the need to disassemble the insulator, which is beneficial to batch breaking of the insulator. At the same time, the insulator enters the breaking chamber vertically in series, and will not cause material accumulation in the breaking chamber during batch breaking.

[0035] As shown in Figure 1 , Figure 3 , the upper part of the feeding port is provided with a blanking mechanism 6; the blanking mechanism 6 comprises a servo motor 61, a lead screw 62, and a supporting and dragging assembly at the low end outlet of the slide rod 32, the supporting and dragging assembly being two parallel horizontal supporting rods 63; one end of the supporting rod 63 away from the slide rod 32 is threadedly connected with the lead screw 62; one end of the supporting rod 63 close to the slide rod 32 is slidingly connected with the sliding groove of the rack 3; the two ends of the lead screw 62 are rotatably connected with the rack 3 through bearings, and the servo motor 61 drives the lead screw 62 to rotate.

[0036] The servo motor 61 drives the two supporting rods 63 to approach the porcelain body 21 supporting the insulator or drives the two supporting rods 63 to move away through the lead screw 62, so that the insulator falls. Specifically, the insulator moves along the slide rod 32 to the low end of the slide rod 32, and finally slides into the space between the two supporting rods 63, and the two supporting rods 63 support the porcelain body 21 part, so that the insulator maintains a vertical state facing the feeding port; such a structure makes the falling position of the insulator controllable and keeps the falling posture vertical, effectively preventing the accumulation of materials in the crushing cavity.

[0037] Preferably, only one insulator can be accommodated on each of the two supporting rods 63 at the same time, and after the current insulator falls, the insulator on the slide rod 32 is automatically replenished into the two supporting rods 63.

[0038] As shown in Figure 3 , Figure 6 , a plurality of feeding channels 31 are arranged in parallel, and the blanking mechanism 6 is provided with a supporting and dragging assembly corresponding to each feeding channel 31. Specifically, the lead screw 62 is a multi-section coaxial connection structure, and each lead screw 62 drives a group of supporting and dragging assemblies; the lead screw 62 drives multiple groups of supporting rods 63 to move away or approach synchronously; multiple groups of supporting and dragging assemblies release the insulators at the same time, which is conducive to the orderly arrangement of the insulators in the crushing cavity for crushing, and not only improves the efficiency, but also avoids the accumulation and return of materials.

[0039] Preferably, the feeding port is provided with a camera facing the crushing cavity, and the camera is electrically connected with the controller. The controller identifies the crushing condition in the crushing cavity through the camera, judges whether the crushing cavity is accumulated with materials, and controls the action of the blanking mechanism 6; the camera is provided with a protective cover to prevent damage to the camera by the crushing action.

[0040] Preferably, a plurality of feeding channels 31 are arranged in parallel, and the blanking mechanism 6 is provided with two independent sets; the two adjacent feeding channels 31 are respectively aligned with the supporting and dragging assemblies of the two sets of blanking mechanisms 6. Through the two sets of blanking mechanisms 6, the action of the corresponding supporting and dragging assemblies can be alternately controlled, so that the insulators at the feeding port position fall into the crushing cavity alternately, effectively controlling the position of the insulators in the crushing cavity and avoiding the accumulation of materials.

[0041] Preferably, the moving jaw tooth plate and the fixed jaw tooth plate of the jaw crusher 1 are vertical teeth. The vertical teeth facilitate the crushing of the insulator; at the same time, the vertical teeth play a role in maintaining the vertical posture of the ferrous accessory 22; the ferrous accessory 22 maintains the vertical state through the discharge port, and the ferrous accessory 22 will be crushed by the moving jaw tooth plate and the fixed jaw tooth plate multiple times; avoiding the ferrous accessory 22 in a horizontal state, the ferrous accessory 22 passes through the discharge port too fast, and is not fully crushed, resulting in the ferrous accessory 22 having undamaged residual ceramic blocks, etc., which requires tedious secondary cleaning work.

[0042] A conveyor belt is arranged below the discharge port of the jaw crusher 1, and the conveyor belt is used to convey the ceramic fragments and the ferrous accessory after crushing. In order to reduce the workload of iron removal after crushing, a magnetic iron removal module is arranged on one side of the conveyor belt, and the magnetic iron removal module is used to adsorb the ferrous accessory from the conveyor belt, so that the ferrous accessory falls into a collection frame for centralized processing.
