Description

Technical Field

[0001] This utility model belongs to the field of coal mine equipment modification technology, and in particular relates to a coal feeder based on the modification of an armored coal feeder. Background Technology

[0002] An armored feeder, also known as an armored belt feeder, is a common type of mining machinery used for continuous feeding. It typically employs a motor-driven cycloidal pinwheel reducer, which drives a drive drum via chain transmission. The drive drum in turn moves a conveyor belt, which in turn moves an armored belt, thus discharging material from the outlet and achieving continuous coal feeding.

[0003] In coal mine production, belt feeders are left idle after shutdown, resulting in a waste of equipment resources as the equipment is not fully utilized. Utility Model Content

[0004] The purpose of this utility model is to provide a coal feeder based on the modification of an armored coal feeder, which improves the idle coal feeder to realize the function of a coal feeder and makes full use of the idle coal feeder.

[0005] The present invention adopts the following technical solution: a coal feeder based on the modification of an armored coal feeder, including a drum drive mechanism, wherein the drum drive mechanism includes a drum; The drum has coaxially arranged sprockets at both ends, which are used to connect with the sprockets on both sides of the belt mounted on the drum when transferring coal; A belt for receiving and transporting gangue is installed on the drum at the original location where the axle belt was installed; A ring plate is installed on the inside of the sprocket, and the outer diameter of the ring plate is larger than the outer diameter of the sprocket.

[0006] The beneficial effects of this utility model are: This utility model replaces the apron on the drum of the original apron-type coal feeder with a belt. When the gangue falls onto the belt, the belt has a certain elasticity and can prevent it from being damaged by the gangue (the apron has poor elasticity, and there is no cushioning when the gangue falls, so it is easily damaged), thus making it suitable for the transfer of gangue.

[0007] Figure 1 This is a schematic diagram of the roller transmission mechanism in an embodiment of the present utility model; Figure 2 This is a schematic diagram of the structure of a single roller in the roller transmission mechanism of this utility model embodiment.

[0008] Among them: 10. belt; 20. sprocket; 30. ring plate; 40. reserved space; 50. roller. Detailed Implementation

[0009] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0010] This utility model discloses a coal feeder based on the modification of an armored coal feeder, such as... Figure 1 As shown, the device includes a roller drive mechanism, which includes a roller 50. The roller 50 has coaxially arranged sprockets 20 at both ends. The sprockets 20 are used to connect with the sprockets on both sides of the belt installed on the roller 50 when transferring coal. A belt 10 for receiving and transporting gangue is installed at the original position of the belt on the roller 50. A ring plate 30 is installed on the inner side of the sprocket 20, and the outer diameter of the ring plate 30 is larger than the outer diameter of the sprocket 20.

[0011] If the armored feeder is used directly for the transfer of gangue, the gangue falling onto the armored belt will damage it (because the armored belt is tightly stretched on the drum 50 and sprocket 20 and has very little elasticity). Therefore, this invention replaces the armored belt on the drum 50 of the original armored feeder with a belt 10. When gangue falls onto the belt 10, the belt 10 has a certain degree of elasticity, which can prevent it from being damaged by the gangue (the armored belt has poor elasticity, and there is no cushioning when the gangue falls, making it easy to be damaged), thus making it suitable for the transfer of gangue.

[0012] Before the improvement, when the armor belt was installed on the roller 50, the sprocket 20 simultaneously connected the chains on both sides of the armor belt to achieve belt transmission. In this utility model, the roller 50 of the armored coal feeder is not modified and is used directly. However, during the process of transporting gangue by the belt 10, since the coal feeder does not have a belt anti-deviation device, the belt 10 will deviate during the falling of gangue and the operation of the belt 10. When the belt 10 deviates, the edge of the belt will press against the sprocket 20 at the end of the roller 50. After running for a period of time, the belt 10 will be severely damaged and needs to be replaced. Therefore, in this utility model, a ring plate 30 is added to the inner side of the sprocket 20. When the belt deviates, the ring plate 30 acts as a stop for the belt, preventing the belt from pressing against the teeth on the outer circumference of the sprocket 20, reducing the degree of belt damage, and improving the service life of the belt.

[0013] In one embodiment, because the length of the roller is close to the width of the belt (2-4 cm), installing the ring plate 30 is somewhat difficult. Therefore, the ring plate 30 is composed of several arc-shaped plates connected end to end. To reduce the difficulty of installing the ring plate 30 as a whole, the arc-shaped plates can be welded onto the sprocket 20 one by one.

[0014] Furthermore, such as Figure 2As shown, to further reduce installation difficulty, a reserved space 40 is provided between the inner diameter of the ring plate 30 and the outer circumference of the roller 50. This allows for welding space at the inner diameter of the ring plate 30, facilitating operation. Moreover, when the belt 10 deviates from its designated path, a portion of the belt will be engaged in the reserved space 40, which acts as a limit to the belt 10, preventing the deviation from increasing.

[0015] In this embodiment of the invention, a camera is also included, which is directed towards the drum drive mechanism. This allows the operator to observe the drum drive mechanism of the coal feeder (modified from a coal feeder) through the camera, and to promptly perform manual repairs if belt misalignment is detected.

[0016] In this embodiment, the length of the roller is 920cm, the width of the installed belt is 900cm, the difference between the outer diameter of the ring plate 30 and the outer diameter of the roller 50 is 6~10cm, and the height of the reserved space 40 is greater than the thickness of the belt 10.

[0017] In summary, the improved version of this utility model can increase the utilization rate of the armored coal feeder, realize the transfer of gangue, reduce the damage cycle of the belt 10, reduce the workload of maintenance personnel, and improve production efficiency.
