The utility model discloses when using, the first drive arrangement of drive drives first gear revolve, and the rotation of first gear drives rack lateral shifting, and the lateral shifting of rack drives on the take-up pulley overhead promotes the belt to the tensioning promotes the belt, avoids causing the drawing that promotes the belt, leads to promoting the belt to be elongated, and the condition that influences handling efficiency appears.

Preferably, racks are connected to both sides of the first gear. This preferred scheme's setting makes the motion direction of two racks opposite, can carry out the tensioning to promoting the belt to the inside both sides of annular promotion belt from promoting the belt simultaneously, improves tensioning efficiency.

Preferably, a plurality of first gears are uniformly arranged in the height direction of the bracket. This preferred scheme sets up a plurality of first gears, sets up a plurality of racks promptly, sets up a plurality of take-up pulleys promptly, makes at the in-process that promotes the belt tensioning, and the take-up pulley of arranging along the direction of height is simultaneously to promoting the belt tensioning, avoids when single take-up pulley carries out the tensioning, promotes the belt bump, when the hopper passes through the bump, can appear shaking, causes the grit in the hopper to break away from the hopper to influence the normal promotion of grit.

Preferably, the rack is connected with a tensioning wheel rotating shaft which is connected to the support in a sliding mode, and the tensioning wheel rotating shaft is connected with the tensioning wheel through a bearing. This optimization scheme passes through the setting of take-up pulley pivot sliding connection on the support, provides the guide effect for the take-up pulley pivot removes.

Preferably, the rack is connected with the tension wheel through a spring. This optimization scheme passes through the setting of spring, makes the rack when promoting the take-up pulley pivot and remove, gives the take-up pulley pivot with the cushioning effect to make the slow tensioning of take-up pulley promote the belt, avoid the tensioning too fast and cause the too big condition of tensioning range to appear.

Preferably, the first driving device comprises a driving shaft rotatably connected to the bracket, and a second gear sleeved on the driving shaft, the first gear is also sleeved on the driving shaft, and the second gear is connected with an output shaft of the motor through a chain.

When the gear rack is used, the adjusting motor drives the chain to move, the chain drives the second gear to rotate, and the rotation of the second gear drives the coaxial first gear to rotate, so that the gear rack is driven to move.

Preferably, the rack sleeve is fixed on the bracket, and the rack is slidably connected in the rack sleeve. The optimized scheme plays a role in protecting the rack through the arrangement of the rack sleeve; and simultaneously, the function of guiding the rack is also achieved.

The utility model has the advantages that: through the arrangement of the first gear, the rack, the tensioning wheel and the first driving device, the stretched lifting belt can be tensioned in time, so that the continuous carrying of the gravels is not influenced; the racks with opposite movement directions are arranged, so that the two ends of the belt can be tensioned and lifted at the same time, and the tensioning efficiency is improved; through the arrangement of the spring; the buffer function is achieved; through the setting of rack cover, play the guide effect who gives the rack motion.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

Referring to the attached drawings 1-3, the utility model relates to a lifting machine for promoting grit, including lifting machine belt 1, promote inside support 2 that is equipped with 11 rigid couplings of lifting machine box of belt, support 2 rotates in the direction of height and is connected with a plurality of drive shafts, has cup jointed first gear 4 and second gear 3 in the drive shaft, the meshing has chain 10 on the second gear 3, and chain 10 is connected to on the output shaft of motor.

Rack 5 has all been meshed to the both sides of first gear 4, rack 5 cup joints rack cover 6 of fixing on the support outward, rack 5 passes rack cover 6 one end rigid coupling and has spring 7, the one end that rack was kept away from to spring 7 is connected take-up pulley pivot 8, take-up pulley pivot 8 is followed rack 5 direction of motion sliding joint on support 2, take-up pulley 9 through the bearing connection has still been cup jointed on the take-up pulley pivot 8, take-up pulley 9 can push up to promoting on the belt 10 under the promotion of rack.

The utility model discloses when using, the regulation motor operation, the rotatory 10 pulling second gears 3 rotations of drive chain of motor output shaft, the rotation of second gear drives first gear 4 and rotates, thereby make the 5 transverse motion of rack that are located first gear 4 both ends, rack 5 promotes 8 lateral shifting of take-up pulley pivot through spring 7, then take-up pulley 9 pushes up to promoting on the belt, realize promoting the outside tensioning of belt, thereby timely tensioning promotes the belt, do not influence the continuation transport of grit, do not influence the continuation of production.

When the tension pulley is pushed to the lifting belt, the tension pulley is driven by the lifting belt to rotate continuously by taking the tension pulley rotating shaft as an axis.
