Description

TECHNICAL FIELD

[0001] The application relates to the technical field of heavy hammer type counterweight boxes, and particularly relates to a sealed adjustable heavy hammer type counterweight box. BACKGROUND

[0002] A belt conveyor is a kind of mechanical device for continuously transporting materials by friction driving, and is widely used in raw material transportation of enterprises such as coal mines, sintering, ironmaking, coking and ports. The heavy hammer type tensioning mode is widely used in the field of belt conveyors due to simple structure, low cost and low maintenance cost.

[0003] In order to adjust the internal counterweight, the top of the existing heavy hammer type counterweight box is often not closed. In a long-term production process, the materials adhered on the belt conveyor belt will fall into the counterweight box, causing uneven counterweight and belt deviation. Therefore, the accumulated materials need to be cleaned, but it is difficult to clean due to the structure. If the top of the counterweight box is directly closed and welded, although the internal accumulated material problem is solved, the adjustment function of the counterweight block in the counterweight box is also lost, and therefore needs to be improved. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the problem that the counterweight box of the belt conveyor is difficult to clean the accumulated materials in the box and needs to frequently clean the accumulated materials outside the box in the actual operation process, the application provides a sealed adjustable heavy hammer type counterweight box.

[0006] The sealed adjustable heavy hammer type counterweight box comprises two vertical columns, a connecting frame is slidably arranged on each of the two vertical columns, a counterweight drum is arranged between the two connecting frames, a counterweight box is arranged below the counterweight drum, the counterweight box and the counterweight drum move together through the connecting frame, two movable material blocking plates are arranged on the upper portion of the counterweight box, and the two movable material blocking plates are arranged in a herringbone shape.

[0007] By adopting the above technical scheme, the herringbone-shaped movable material blocking plates can make the ore powder and materials automatically slide to the ground or the platform below, prevent the ore powder and materials from falling into the counterweight box, cause uneven counterweight and belt deviation, and the staff can disassemble the movable material blocking plates, open the internal space of the counterweight box, increase or decrease the counterweight blocks to adjust the counterweight proportion in the counterweight box, and improve the problem that the counterweight box of the belt conveyor is difficult to clean the accumulated materials in the box and needs to frequently clean the accumulated materials outside the box in the actual operation process.

[0008] Preferably, springs are arranged between the two movable material blocking plates and the counterweight box.

[0009] By adopting the technical scheme, the spring can vibrate the movable blocking plate by slightly moving the movable blocking plate, so that the sticky material falling on the surface of the movable blocking plate can be shaken off, thereby improving the convenience of cleaning the surface material and reducing the burden on the workers.

[0010] Preferably, the top end of each of the two movable blocking plates is provided with a support plate, one of the support plates is provided with a clamping groove, and the other support plate is provided with a clamping plate, and the clamping plate and the clamping groove are matched with each other to fix the two movable blocking plates.

[0011] By adopting the technical scheme, the clamping groove and the clamping plate are provided to fix the two movable blocking plates, thereby limiting the displacement of the movable blocking plate, fixing the movable blocking plate, and improving the stability of the counterweight box.

[0012] Preferably, the clamping groove is in a herringbone shape, and the clamping plate is located below the herringbone structure of the clamping groove.

[0013] By adopting the technical scheme, the clamping groove and the clamping plate are in a herringbone shape, which can make the accumulated material on the surface of the clamping groove slide down along the surface of the clamping groove, so that the material falls further on the surface of the movable blocking plate for subsequent cleaning.

[0014] Preferably, the clamping groove and the clamping plate are combined and located at the center position of the two movable blocking plates after being closed.

[0015] By adopting the technical scheme, the clamping groove and the clamping plate are arranged at the center position, which can block the gap between the two movable blocking plates, thereby preventing the material from entering the counterweight box from the gap between the movable blocking plates, and solving the problem that the counterweight box is difficult to clean.

[0016] Preferably, the counterweight box is provided with a fastener for fixing the connecting frame.

[0017] By adopting the technical scheme, the fastener can form a detachable connection between the counterweight box and the connecting frame, thereby improving the assembly and disassembly convenience of the counterweight box, and facilitating the maintenance or replacement of the counterweight box.

[0018] Preferably, the connecting frame on each side is provided with a shaft sleeve, and the counterweight roller is arranged between the two shaft sleeves, and the counterweight roller is rotatably connected to the connecting frame through the shaft sleeves.

[0019] By adopting the technical scheme, the shaft sleeve can effectively improve the smoothness of the rotation between the counterweight roller and the connecting frame, reduce the wear between them, prolong the service life, and make the counterweight roller more stable during work, thereby improving the stability and safety of the counterweight box.

[0020] Preferably, handles are arranged on the two movable material blocking plates.

[0021] By adopting the above technical scheme, the handles arranged on the movable material blocking plates facilitate the operation of the movable material blocking plates by workers, thereby improving the convenience of adjusting the counterweight blocks in the counterweight box.

[0022] To sum up, the present application has at least one of the following beneficial technical effects:

[0023] 1. The arrangement of the movable material blocking plates in a herringbone shape enables the ore powder and materials to automatically slide to the ground or the platform below, preventing the ore powder and materials from falling into the counterweight box and causing uneven counterweight and deviation of the conveyor belt. Workers can disassemble the movable material blocking plates, open the internal space of the counterweight box, and adjust the counterweight ratio in the counterweight box by adding or reducing the counterweight blocks, thereby improving the problem that the accumulated materials in the counterweight box of the belt conveyor are difficult to clean, and the materials accumulated outside the box need to be cleaned frequently during actual operation.

[0024] 2. The arrangement of the spring enables the movable material blocking plates to vibrate by lightly touching them, so that the sticky materials falling on the surface of the movable material blocking plates can be shaken off, thereby improving the convenience of cleaning the surface materials and reducing the burden on workers.

[0025] 3. The arrangement of the clamping groove and the clamping plate facilitates the fixation of the two movable material blocking plates, thereby limiting the limited displacement of the movable material blocking plates, fixing the movable material blocking plates, and improving the working stability of the counterweight box.
