The utility model discloses a prying trolley with a sliding arm frame, which comprises a frame and a working arm frame arranged on the frame, and the frame is provided with an arm frame sliding device which is used for enabling the working arm frame to slide on the frame so as to increase the construction range of the working arm frame. According to the prying trolley with the sliding arm frame, through the arrangement of the arm frame sliding device, the operation range of single operation is enlarged, the construction efficiency of the same height and different depths is improved, and the prying trolley can be achieved only by pushing the working arm frame to slide back and forth through the single operation arm frame sliding device; compared with a traditional fixed arm support, pitching of the arm support and stretching of the arm support need to be adjusted, combined action adjustment is needed for each depth point, operation is complex, construction efficiency is low, and the arm support has the advantages of being wide in single-time construction range and high in construction efficiency.

To provide a working vehicle in which a camera for photographing the rear side of a vehicle body can be arranged below right and left frames of a working device.SOLUTION: The work vehicle includes a vehicle body, a work device connected to the vehicle body, and a camera configured to capture an image behind the vehicle body, the vehicle body includes a vehicle body front-rear frame extending in a front-rear direction and a vehicle body left-right frame extending in a left-right direction and connected to a rearmost portion of the vehicle body front-rear frame, the work device includes a device front-rear frame extending in the front-rear direction and a device left-right frame extending in the left-right direction and connected to a rearmost portion of the device front-rear frame, and the device left-right frame is disposed so as to overlap the vehicle body left-right frame in an up-down direction and has a gap with the vehicle body left-right frame in at least a part in the left-right direction. The camera is disposed in the gap.SELECTED DRAWING: Figure 12

The utility model provides a self-adjusting tension drawing mechanism which comprises a drawing frame conveying support, a mounting plate is arranged above the drawing frame conveying support, a fixing block is arranged on the surface of the top of the mounting plate, an adjusting cavity is formed in the surface of the top of the fixing block, and first sliding grooves are formed in the inner walls of the two ends of the adjusting cavity. Through cooperative use of the fixing block, the adjusting cavity, the spring, the adjusting block and the conveying groove, automatic tension adjustment can be conveniently conducted on conveyed cotton slivers when the drawing frame works, so that during operation, the cotton slivers are conveyed through the limiting rollers, then a worker presses the adjusting block to compress the spring, the cotton slivers are conveyed through the limiting rollers, and the cotton slivers are conveyed through the adjusting block. The cotton slivers penetrate through the conveying groove to be conveyed, then one ends of the cotton slivers are led into the drawing frame, and therefore in the follow-up work process, under the supporting of the springs, the cotton slivers can be tensioned by the adjusting blocks all the time, automatic adjustment can be achieved according to the elasticity of the springs, and the use flexibility of the cotton slivers is improved.
