Description

Technical Field

[0001] This utility model relates to the technical field of steel ball adding devices, specifically a steel ball adding device. Background Technology

[0002] In mining machinery, the mill is one of the most commonly used pieces of equipment. It uses steel balls to grind ore to achieve the purpose of ore grinding. During the operation of the mill, the steel balls and ore will continuously wear down the inner liner of the cylinder. When the liner reaches the end of its service life, it needs to be replaced. Since there are a large number of steel balls inside the mill, it is generally necessary to open the manual port of the mill before replacing the inner liner. The steel balls inside the cylinder can be poured out through the manual port before the inner liner can be replaced. After the inner liner of the mill cylinder is replaced, the steel balls are collected again in ton bags and need to be added back through the manual port.

[0003] However, in the existing technology, the manual inlet of the ball mill is relatively small when adding steel balls. When adding steel balls again, due to the small manual inlet, there is a significant safety hazard when lifting the ton bag full of steel balls. The speed of steel ball addition (process) is not easy to control, and there is a risk of steel balls scattering. The labor intensity is high and the risk is relatively high.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a steel ball adding device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a steel ball adding device includes a feeding hopper 1, which is funnel-shaped. Support plates 2 are fixedly installed on the upper ends of both the left and right sides of the outer surface of the feeding hopper 1. The lower ends of the support plates 2 are arc-shaped. Guide rods 3 are fixedly installed in the middle of both the left and right sides of the outer surface of the feeding hopper 1. Lead screws 4 are rotatably connected to both the left and right sides of the outer surface of the feeding hopper 1 below the guide rods 3. A handwheel 6 is fixedly installed at the end of the lead screw 4 away from the feeding hopper 1, passing through the support plate 2. A movable plate 5 is fitted onto the surfaces of the guide rods 3 and the lead screw 4. The movable plate 5 is slidably connected to the guide rods 3 and threadedly connected to the lead screw 4. A locking mechanism 7 is provided on the side of the support plate 2 away from the feeding hopper 1.

[0023] By adopting the above technical solution, the funnel shape of the feeding hopper 1 allows the bottom of the feeding hopper 1 to be inserted into the ball mill feed inlet, while the widening of the upper end of the feeding hopper 1 expands the opening range of the ball mill feed inlet, making it easier to add steel balls.

[0024] When the bottom of the feeding hopper 1 is inserted into the ball mill feed inlet, the movable plate 5 is also located at the feed inlet;

[0025] Under the limit of the guide rod 3, the movable plate 5 cannot rotate with the lead screw 4, and can only move under the thread thrust generated by the lead screw 4 during rotation;

[0026] Rotating the lead screw 4 causes the movable plate 5 to move towards and fit against the side wall of the ball mill feed inlet, while the two movable plates 5 simultaneously abut against the side wall of the ball mill feed inlet. As the left and right abutment plates jointly apply a reverse thrust, the entire feeding hopper 1 can be fixed in the middle position of the ball mill opening.

[0027] Furthermore, the locking mechanism 7 includes positioning holes 701 evenly distributed around the through portion of the lead screw 4 on the surface of the support plate 2. A pin 702 is slidably inserted into the positioning hole 701, and the end of the pin 702 away from the positioning hole 701 slides through the handwheel 6.

[0028] By adopting the above technical solution, the positioning hole 701 positions the pin 702 in the direction of rotation, so that the pin 702 positions the handwheel 6, preventing the handwheel 6 from rotating.

[0029] Furthermore, the locking mechanism 7 also includes a fixing plate 703 fixedly mounted on the surface of the pin 702. A spring 704 is fixedly mounted on the side of the fixing plate 703 away from the positioning hole 701. The end of the spring 704 away from the fixing plate 703 is fixedly connected to the handwheel 6.

[0030] By adopting the above technical solution, the spring 704 can push the pin 702 to be stably inserted into the positioning hole 701 using the fixing plate 703.

[0031] Furthermore, the upper left and right sides of the feeding hopper 1 are fixedly installed with hanging ears 8, and the upper side of the feeding hopper 1 is provided with a cross frame 9, the length of which matches the horizontal length of the feeding hopper 1.

[0032] Hooks 10 are fixedly installed on both the left and right sides of the lower surface of the cross frame 9. The hooks 10 are connected to the hanging ears 8 and the position of the hooks 10 matches that of the hanging ears 8.

[0033] By adopting the above technical solution, the hook 10 can be quickly attached to the lug 8, and the length of the cross frame 9 matches the feeding hopper 1, which ensures that the entire cross frame 9 and the feeding hopper 1 are centered and aligned when the hook 10 is attached.

[0034] Furthermore, cables 11 are fixedly connected to both the left and right sides of the upper surface of the cross frame 9, and the upper end of the cables 11 is fixedly connected to the same hook 12, which is located above the middle position of the cross frame 9.

[0035] By adopting the above technical solution, the hook 12 can be connected to the overhead crane, that is, the entire feeding hopper 1 can be lifted by the hook cable 10 and transported to the ball mill feed inlet for installation;

[0036] The hook 12 is also located in the center of the cross frame 9, which ensures that the entire cross frame 9 and the feeding hopper 1 remain vertical when lifted.

[0037] Working principle: When using this steel ball adding device, firstly, the hook 10 is hooked to the hanging ear 8, and the hook 12 is attached to the crane trolley, so that the entire feeding hopper 1 can be directly lifted for transportation. Mechanical assistance makes it easier to assemble the feeding hopper 1 with the ball mill's feed inlet. The entire feeding hopper 1 is then supported on the surface of the ball mill using the support plate 2, with the bottom of the feeding hopper 1 inserted into the ball mill's feed inlet. The movable plate 5 is also located at the feed inlet. Then, the pin 702 is manually pulled out of the positioning hole 701, at which point the handwheel 6 can rotate. Rotating the screw 4, the movable plate 5, limited by the guide rod 3, cannot follow the screw 4's rotation, but can only move under the threaded thrust generated by the screw 4 during rotation. This causes the movable plate 5 to move towards and fit against the side wall of the ball mill's feed inlet, while both sides of the movable plate 5 simultaneously abut against the side wall of the ball mill's feed inlet. Due to the combined action of the left and right abutment plates... A reverse thrust is applied to fix the entire feeding hopper 1 in the middle of the ball mill opening. After the feeding hopper 1 is fixed, the pin 702 is manually released. Under the elastic force of the spring 704, the fixing plate 703 pushes the pin 702 into the nearest corresponding positioning hole 701, thereby positioning the pin 702 in the rotational direction. The pin 702 passes through the handwheel 6, preventing the handwheel 6 from rotating and locking the screw 4. This prevents the screw 4 from rotating again due to the impact when adding steel balls, thus avoiding the displacement of the movable plate 5. This makes the feeding hopper 1 more stable. After the feeding hopper 1 is installed, the upper end of the feeding hopper 1 expands the opening size of the entire ball mill feed inlet. Subsequently, the packaged steel balls are lifted by a crane and moved to the top of the feeding hopper 1, and then the steel balls are unloaded to complete the steel ball addition. This is the working principle of the steel ball adding device.
