The utility model provides a plate shearing machine with a protection structure, and relates to the technical field of plate shearing machine equipment, the plate shearing machine comprises a workbench and a motor, a feeding roller support is embedded in the position, close to the front side, of the top of the workbench, and sliding grooves are formed in the positions, close to the left side and the right side, of the top of the workbench; and a U-shaped frame is slidably arranged between the interiors of the two sliding grooves, supports are symmetrically and fixedly installed at the top of the U-shaped frame, and electric push rods are fixedly installed at the bottoms of the supports. According to the plate feeding device, the bottom of a plate is supported through the feeding roller carrier, the plate is clamped and fixed through the cooperation of the feeding roller carrier and the electric push rod, the U-shaped frame is driven by the motor to move backwards, and therefore the plate can be pushed to move backwards synchronously, and due to the fact that the bottom of the plate is supported by the feeding roller carrier, when the plate moves, the feeding roller carrier rolls due to friction force; therefore, scratches caused by direct contact between the workbench and the plate are avoided, machining quality is improved, meanwhile, manual plate pushing is avoided, and potential safety hazards are reduced.

The utility model discloses a telescopic cantilevered caterpillar type whole row tobacco rack automatic feeding device belongs to agricultural machinery field, including the chassis, the left end in -fixed mounting of chassis has two groups drive motor, the left and right both ends of chassis all are installed two groups of driving wheels, and the both ends driving wheel of chassis left end is fixedly connected with the output shaft of two groups drive motor, and four groups driving wheel are sleeved with two groups caterpillar, the front and back both sides of chassis all rotatory installation has a plurality of guide wheels, the front and back both sides of chassis all rotatory installation has a plurality of support rod, and the upper end of a plurality of support rod's front and back both sides junction of chassis all is provided with shock absorber, through above -mentioned each device between the cooperation use, through the composition and mutual cooperation of elevating system, opening and closing mechanism and propulsion mechanism, make the device can flexibly adjust the position of two groups of clamping frame, and the height range covers various baking room frame height, ensure and tobacco rack vertical butt joint, in-depth frame inside.
