Apron feeder is generally divided into heavy, medium and light three, is commonly used in concentrator feeding equipment. Apron feeder is a continuous transport machine widely used in mining, gold, building materials, port, coal and chemical industry and mining enterprises. It is mainly used for the continuous and uniform supply and transfer of various large weights and abrasive bulk materials from the storage bin or transfer funnel to the crusher, batching device or transportation equipment. It is one of the important and essential equipment in the ore and raw material processing and continuous production process.
Apron feeder can be installed horizontally or tilted, with a maximum upward angle of 20 degrees. It is generally suitable for materials with loose density less than 1200kg/m3, block weight less than 140kg and temperature below 350℃. The existing apron feeder tilt is already fixed when it is reproduced, and it is usually necessary to choose the most suitable tilt angle when transporting different materials. So existing apron feeder is difficult to adjust its tilt angle.
To address the shortcomings of the existing technology, we provide an adjustment mechanism that can adjust the tilt angle for apron feeder.
Apron feeder tilt adjustment mechanism, including a base, screw, adjusting nut, connecting rod, supporting seat and flat plate adjusting cam, the flat plate adjusting cam is hinged on the supporting seat, both sides of the supporting seat are symmetrically provided with two supporting frames, both ends of the screw and the supporting frame rotation connection, the screw is provided with two equal pitch, opposite screw threads, and the two sections of thread are symmetrical about the middle of the screw, the screw on two sections of thread are provided with the nut, two adjusting nuts and flat adjusting cam are provided with the connecting rod, one end of the connecting rod is hinged with the nut, the other end of the connecting rod is hinged with the flat adjusting cam, two connecting rod and flat adjusting cam hinged position and flat adjusting cam hinged spacing is equal, the flat plate adjusting cam is offset with the bottom of the feeding groove. When using the above technical scheme, rotate the screw, because the screw is provided with two segments of equal pitch and opposite screw threads, two segments of screw threads are provided with the nut, two nuts are hinged on the connecting rod, and the other end of the connecting rod is hinged with the flat adjusting cam, so the two nuts can not rotate, only move along the screw axis, and the two nuts move in the opposite direction, when the two nuts move, it can drive the connecting rod, and the two connecting rods move in opposite directions, so it can drive the plate adjusting cam to rotate, because the plate adjusting cam and the apron feeder upper side of the bottom, so when the eccentricity of the plate adjusting cam and the feeding groove upper side of the bottom contact position from small to large, the plate adjusting cam can push the feeding groove upper side of the bottom. The apron feeder tilt angle increases. When the eccentricity of the contact position between the plate adjusting cam and the bottom of the upper side of the feeding trough changes from large to small, the plate adjusting cam can lower the bottom of the upper side of the feeding trough, so that the apron feeder tilt angle decreases. The utility model adjusts the tilt angle of apron feeder through screw, adjusting nut, plate adjusting cam and connecting rod, so that the plate adjusting cam is suitable for transporting different materials. Both ends of the screw are installed on the support frame through the bearing. This can reduce the screw rotation process and. One end of the screw is provided with a rotating arm. By turning the arm to turn the screw, the adjustment process is more effortless. The screw is provided with a lock ring on both sides of the bearing. The locking ring prevents the screw from moving along its axis during the rotation of the screw.
