Description

TECHNICAL FIELD

[0001] The utility model relates to ore screening technical field, concretely relates to a kind of rock separating device for hand sorting belt conveyor. BACKGROUND

[0002] In the existing coal preparation process, especially in the post-processing stage after primary screening, it is usually necessary to separate large lump coal mixed with gangue. This process traditionally relies on hand sorting belt conveyor to realize manual sorting, i.e. the operator stands on both sides of the belt, manually picks out the gangue and moves it to a specific chute to ensure that the large lump coal can be effectively recovered. However, this mode of operation has several significant shortcomings:

[0003] Firstly, since the large lump coal and gangue inevitably collide during their descent through the chute, the on-site environment is exceptionally noisy and the dust concentration is extremely high, which seriously affects the working conditions of the operators. To protect the health of employees, they must be required to wear earplugs and professional dust masks and other protective equipment, but this does not completely solve the problem of occupational disease risk that may be caused by long-term exposure to a harsh environment.

[0004] Secondly, manual sorting is not only inefficient but also costly. At least two workers are required to work simultaneously per shift, and they need to rotate positions every hour to reduce fatigue, which undoubtedly increases labor costs. In addition, as labor costs rise year by year, how to reduce this part of the expenditure has become a major challenge faced by coal preparation plants.

[0005] In view of the above situation, the utility model aims to provide an improved rock separating device for hand sorting belt conveyor, which can significantly reduce the required manual intervention while maintaining efficient sorting, thereby improving the working environment, reducing operating costs, and improving overall production efficiency.

DETAILED DESCRIPTION

[0018] The content of the present application will be described in detail below by combining with Figs. 1-2 EMBODIMENT

[0019] The rock separating device comprises the hand sorting belt conveyor 1, and the gangue chutes 3 are correspondingly arranged on the left and right sides of the hand sorting belt conveyor. In the rear side position close to the gangue chute, the cylinder support 4 is arranged across the hand sorting belt conveyor. The cylinder 7 is arranged on the upper part of the cylinder support and can be extended and retracted forward. The cylinder is hingedly fixed with the cylinder support through the hinged seat 401, so that the cylinder is stably connected and can rotate within a certain range. The rock separating mechanism supports 5 are also correspondingly arranged on the left and right sides between the gangue chutes and the cylinder support and are fixedly connected with the ground. The rock separating mechanism is hingedly arranged between the rock separating mechanism supports.

[0020] The rock separating mechanism comprises the angular baffles 602 arranged between the left and right gangue chutes, the triangular connecting plates 603 fixedly arranged on the front side of the angular baffles, the hinged plates fixedly arranged on the upper part of the triangular connecting plates, and the connecting plates 601 fixedly arranged on the left and right sides of the angular baffles. The angular baffles are hingedly connected with the rock separating mechanism supports through the connecting plates. The U-shaped pieces 701 are fixedly arranged on the extension end of the cylinder and are hingedly connected with the hinged plates, so that the lifting or falling action of the rock separating mechanism can be controlled by the extension and retraction of the cylinder 7.

[0021] In order to protect the extension rod of the cylinder 7 from being damaged by the impact of materials, the protection assembly 8 for protecting the extension rod of the cylinder is arranged on the triangular connecting plate.

[0022] Preferably, the baffles 9 for preventing the stone from separating from the hand sorting belt conveyor are arranged on the left and right sides between the gangue chutes and the cylinder support, so that the direct impact of the coal blocks and other materials on the extension rod is effectively prevented.

[0023] ​Preferably, the protection assembly comprises two supporting plates fixed on the triangular connecting plate and a blocking groove fixedly connected between the two supporting plates.

[0024] In order to accurately control the extension distance of the cylinder 7, prevent the rock separating mechanism from accidentally scratching the belt of the hand sorting belt conveyor 1, corresponding sensors are fixed on the cylinder 7 at intervals, and a blocking piece moving with the extension rod of the cylinder is arranged between the sensors. The blocking piece is fixedly connected to the extension rod of the cylinder 7 through an L-shaped support, and when the blocking piece moves between the sensors, the corresponding signals can be triggered, thereby controlling the action range of the cylinder 7 and ensuring the safety and accuracy of the operation.

[0025] The use method of the utility model discloses a method for using the hand sorting belt conveyor 1, which comprises the following steps:

[0026] The on-site operator determines whether to lift or drop the rock separating mechanism according to the material entering the tail. When the proportion of large coal in the material entering is large, the hand sorting rock separating mechanism is lifted, and the operator picks out the gangue and puts it into the gangue chute 3 using a tool; if the proportion of gangue in the material entering is high, the rock separating mechanism is lowered, so that the gangue is scraped off to the gangue chute 3 on the two sides, and at the same time, the coal blocks smoothly pass through the hand sorting belt conveyor 1 and enter the next processing procedure.

[0027] Through the above design, the utility model not only reduces the required manual intervention and reduces the labor intensity, but also improves the work efficiency.
