Furthermore, two first waist-shaped holes are formed in the bearing fixing carriage, and the bearing fixing carriage and the fixing backboard are detachably connected by respectively penetrating through the two first waist-shaped holes and screwing the two bolts on the fixing backboard; waist-shaped through holes for the mounting shaft heads of the tensioning rollers to penetrate are formed in the side plates of the rack and the fixed back plate.
Furthermore, a first stop block is arranged on the bearing fixing carriage, a second stop block is arranged on the fixing back plate, a threaded hole is formed in the first stop block, a through hole is formed in the second stop block, the threaded hole and the through hole are coaxially arranged in the front-back direction, an adjusting screw rod is arranged in the threaded hole and the through hole and is in threaded connection with the threaded hole, four nuts are sleeved on the adjusting screw rod in a threaded mode, and the four nuts are located on the front side and the back side of the first stop block and the front side and the back side of the second stop block respectively.
Furthermore, the bearing with the seat is arranged on the bearing fixing planker through a screw.
Furthermore, the fixed back plate is installed on the side plate of the frame through screws.
Compared with the prior art, the utility model has the following advantages:
according to the adjustable heavy-duty belt tensioning roller device, the tensioning rollers are respectively rotatably installed in the bearing inner holes of the bearings with the seats through the installation shaft heads at the two ends, the original embedded bearings are changed into external bearings with the seats, the bearing capacity of the bearings is greatly enhanced, the service life of the bearings is prolonged, and therefore the service life of the tensioning rollers is prolonged. In addition, it has first waist shape hole to open on the fixed planker of bearing, and all opens the waist shape perforation that the installation spindle nose that supplies the tensioning roller passed on frame curb plate and fixed backplate, position around the adjustable tensioning roller to the rate of tension of adjustment tensioning roller to the belt has effectively prevented the phenomenon of off tracking from appearing in the belt.

Detailed Description
The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
Referring to fig. 1 to 3, this embodiment discloses an adjustable heavy load belt tensioning roller device, and the axial of tensioning roller 1 extends along left right direction, and both ends are installed respectively on the frame curb plate 2 of heavy load belt feeder about tensioning roller 1, and the frame curb plate 2 outside is fixed with a fixed backplate 3, and fixed backplate 3 passes through the mounting screw on frame curb plate 2. A bearing fixing carriage 4 is arranged on the outer side of the fixing back plate 3, a bearing with seat 5 is arranged on the outer side of the bearing fixing carriage 4, and the bearing with seat 5 is arranged on the bearing fixing carriage 4 through a screw. The mounting shaft heads 6 at the left end and the right end of the tensioning roller 1 are respectively rotatably mounted in the bearing inner holes of the bearing with the seat 5. This embodiment changes original embedded bearing into the external rolling bearing 5 in both ends, has strengthened the bearing capacity of bearing greatly, has prolonged the life of bearing to the life of tensioning roller 1 has been prolonged.
