Detailed implementation manners

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] A noise reduction component for a steel ball strengthening machine, as Figures 1 - 6 shown, includes a sound insulation box 1 and a loading component 2. The steel ball strengthening machine is arranged inside the sound insulation box 1, and the sound insulation box 1 is used to reduce the sound transmission, thereby reducing the noise pollution. Among them, a feeding port 11 is arranged on the sound insulation box 1, and a switch component is arranged at the feeding port 11 to control the opening and closing of the feeding port 11 by using the switch component; the loading component 2 is arranged on one side of the sound insulation box 1, and the steel balls are sent into the strengthening machine by using the loading component 2;

[0025] The loading component 2 includes a fixed bracket 21, a lifting bracket 22, an actuator 23, a placing table 24 and a telescopic chute component 25. The lifting bracket 22 is vertically slidably arranged on the fixed bracket 21, and the actuator 23 is used to drive the lifting bracket 22 to move up and down. The placing table 24 is arranged on the lifting bracket 22, and the telescopic chute component 25 connects the discharge port of the placing table 24 and the feeding port of the steel ball strengthening machine; when loading, the telescopic chute component 25 passes through the feeding port 11 of the sound insulation box 1 and connects the feeding port of the steel ball strengthening machine, and then the steel balls are sent into the strengthening machine through the telescopic chute component 25. When the steel ball strengthening machine is working, the telescopic chute component 25 moves out of the sound insulation box, so that the switch component can close the feeding port 11.

[0026] In an embodiment, as Figures 1 - 6As shown, the switch assembly includes a sound-insulating door 12 and a first cylinder 13. The sound-insulating door 12 is slidably arranged on the side wall of the sound-insulating box 1. The first cylinder 13 drives the sound-insulating door 12 to move to control the opening and closing of the feeding port 11 of the sound-insulating box 1. Among them, guide rails are vertically arranged on the left and right sides of the feeding port 11 of the sound-insulating box 1. Both sides of the sound-insulating door 12 are slidably connected to the guide rails. The first cylinder 13 is fixed on the sound-insulating box 1 and connected to the sound-insulating door 12 to control the vertical movement of the sound-insulating door 12 through the first cylinder 13. Of course, the guide rails can also be horizontally arranged on the upper and lower sides of the feeding port 11. The guide rails cooperate with the sound-insulating door 12 to control the horizontal movement of the sound-insulating door 12 through the first cylinder 13.

[0027] In one embodiment, as Figures 1 - 6 shown, the actuator 23 is an oil cylinder. Due to the large total mass of the steel balls, a large driving force is provided by the oil cylinder to lift the steel balls to a specified height.

[0028] In one embodiment, as Figures 1 - 6 shown, the placement table 24 includes a placement bracket 241 and a placement plate 242. The placement plate 242 is obliquely fixed on the placement bracket 241. A discharge port is provided on the placement plate 242, and a baffle 243 is arranged around the discharge port on the upper surface of the placement plate. A guiding part 244 is convexly provided on the lower surface of the placement plate 242 to guide the steel balls to the telescopic chute assembly 25 by means of the guiding part 244. During use, the steel ball container is placed on the placement plate 242. Since the placement plate 242 is obliquely arranged, the steel ball container will slide down along the placement plate 242 until it is blocked by the baffle 243. At this time, the discharge port of the steel ball container corresponds to the discharge port of the placement table 241, and the baffle 243 plays a role in limiting and positioning. The guiding part 244 is an inclined channel to guide the steel balls through the guiding part 244 to prevent the steel balls from sliding around when falling.

[0029] In the above embodiment, as Figures 1 - 6 shown, guide edges 247 are arranged on both sides of the placement plate 242 to guide the movement of the steel ball container and perform lateral positioning on the steel ball container.

[0030] In one embodiment, as Figures 1 - 6 shown, the placement table 24 further includes an anti-blocking component. The anti-blocking component includes a stirring rod 245 and a second cylinder 246. The stirring rod 245 is arranged on the second cylinder 246, and the second cylinder 246 is used to drive the stirring rod 245 to move back and forth to insert the stirring rod 245 into the steel ball container. Since the steel balls are stacked in the container, there will be a situation of wire storage and material jamming. Through the arrangement of the stirring rod 245, the steel balls are intervened regularly through the stirring rod 245, which can promote the steel balls to slide out of the container.

[0031] In one embodiment, as Figures 1 - 6As shown, the end of the stirring rod 245 is provided with a rounded corner to avoid damaging the steel balls. Preferably, the stirring rod 245 can be wrapped with a rubber layer to further protect the steel balls.

[0032] In one embodiment, as Figures 1 - 6 shown, the telescopic chute assembly 25 includes a chute 251 and a driving assembly. The chute 251 is slidably arranged on the storage table 24, and the driving assembly is used to control the front and back movement of the chute 251. Wherein, slide rails are arranged on both sides of the chute 251, and sliders cooperating with the slide rails are arranged at corresponding positions on the storage table 24, so as to realize the sliding connection between the chute 251 and the storage table 24.

[0033] In the above embodiment, as Figures 1 - 6 shown, the driving assembly includes a rack 252, a gear 253 and a motor 254. The rack 252 is arranged at the bottom of the chute 251, the gear 253 is arranged on the motor 254, the gear 253 meshes with the rack 252, and the motor 254 is used to drive the gear 253 to rotate, so as to drive the rack 252 to drive the chute 251 to move back and forth. By adopting the movable chute 251, the normal operation of the switch assembly can be avoided from being affected by the chute 251.

[0034] In one embodiment, as Figures 1 - 6 shown, a foot support 26 is arranged at the bottom of the fixed bracket 21, a screw rod 27 is arranged on the foot support 26, and the screw rod is in threaded cooperation with the fixed bracket 21. Preferably, the screw rod 27 is rotatably connected to the foot support 26, and a turning part cooperating with a wrench is arranged on the screw rod 27. By rotating the screw rod 27, the height position of the fixed bracket 21 can be adjusted, and then the height position of the chute 251 can be adjusted within a small range.

[0035] When the utility model is in use, as Figures 1 - 6 shown, tools such as a forklift can be used to place the steel ball container on the placement board 242. After being placed in place, the lifting bracket 22 is driven by the actuator 23 to be lifted to a specified position, and then the feeding port is opened through the switch assembly of the sound insulation box 1; at this time, the feeding port of the strengthening machine corresponds to the feeding port of the sound insulation box 1, and the chute 251 is driven to move through the telescopic chute assembly 25 so as to extend the chute 251 into the feeding port. The staff can be sent to a high place through a maintenance ladder or a high-altitude device, the discharge port of the steel ball container is opened, so that the steel balls are sent into the strengthening machine through the chute 251. In this process, the second cylinder 256 drives the stirring rod 245 to reciprocally extend into the steel ball container to stir the steel balls. After the feeding is completed, the telescopic chute assembly 25 resets, and then the switch assembly and the actuator 23 reset, the empty steel ball container is taken away, and a full steel ball container is put in, waiting for the next feeding. In this process, it is specially set that the staff manually opens the steel ball container through a maintenance ladder, so that the staff can observe whether each device is in place by visual inspection at a high place, increasing the means of manual inspection.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model; any modifications or equivalent replacements made to the present utility model without departing from the spirit and scope of the present utility model shall be covered by the protection scope of the claims of the present utility model.
