The invention relates to the technical field of agricultural machinery, in particular to a self-propelled field weeding machine. The self-propelled field weeding machine is used with a mini-tiller and is used for weeding rapeseed fields or broad bean fields with certain row spacing. The self-propelled field weeding machine is characterized in that the upper ends of telescopic handles penetrate square holes of fixing seats and are fixed into the fixing seats by the aid of jackscrews, and shovels are fixed to the lower ends of the telescopic handles by the aid of bolts; a fixing connecting frame is welded on the side, which is opposite to the fixing seats, of the middle of a large frame, and a connecting pin hole is longitudinally fixedly formed in the front end of the fixing connecting frame by means of welding; a telescopic pipe sleeve is connected to the rear end of a side of the fixing connecting frame by means of welding, a telescopic pipe is fixed into the telescopic pipe sleeve by the aid of an ascending limiting wheel adjusting handle, and an ascending limiting wheel is fixed to the lower end of the telescopic pipe by the aid of a wheel carrier. The self-propelled field weeding machine has the advantages that the overall height of the self-propelled field weeding machine is controlled by the ascending limiting wheel, good profiling effects can be realized by the three shovels, and proper and accurate weeding row spacing can be adjusted via U-shaped bolts; the self-propelled field weeding machine is simple in structure and convenient to use, can be operated easily and conveniently and is a perfect agricultural machine, and the weeding efficiency can be obviously improved.

The invention relates to a large-wall thick-steel plate double-edge edge milling machine. The edge milling machine comprises an entrance conveying roller device, wherein a centering device is mounted on the entrance conveying roller device; the rear end of the entrance conveying roller device is connected with a milling device, an exit conveying roller and a surface chip removal device; and a clamping vehicle reciprocates on a track among the entrance conveying roller device, the milling device, the exit conveying roller and the surface chip removal device. The machine provided by the invention is compact and reasonable in structure and convenient to operate; the whole machine adopts full-automatic control of CNC; a console is provided with a human-machine interface for inputting the wall thickness, plate width, length and material of the steel plate; and the working parameters of each execution part of the edge milling machine are automatically determined. A power box of the edge milling machine is driven by a gear and has high rigidity and strong cutting ability; a steel plate can be conveniently guided into / out of the edge milling machine; in edge milling, the condition that a pressure roller in the middle touches the steel plate can be ensured, and the profiling effect in cutting is good; and the centering, clamping and milling of the steel plate are controlled by a servo motor, the positioning is accurate, and the groove dimensional accuracy is high.

The invention belongs to the technical field of pasture harvesting, and relates to a small self-propelled disc type mowing-flattening harvesting machine. The small self-propelled disc type mowing-flattening harvesting machine comprises a walking part and a disc type mowing-flattening mechanism, wherein a power transmitting system of the harvesting machine is arranged at the right side of a vehicle body, a cab (15) is arranged at the left side of the vehicle body, and the disc type mowing-flattening mechanism is installed at the front end of the walking part. The small self-propelled disc type mowing-flattening harvesting machine has the advantages that a dual-clutch mechanism is adopted to separate the power of the walking part and a working part, so the functions of the two parts are not mutually influenced, and the mechanical handling performance and security is increased; the whole structure is simple and compact due to the adopted arrangement mode, and the harvesting machine is more suitable for small meadows or is not suitable for terrains using large-middle mowing flattening mills; double discs are adopted, so the cutting length is short, the ability of adapting the terrain is strong, and the profile effect is good; a parallel four-bar mechanism, a hydraulic system and a sliding palm are adopted, so that a certain profile effect can be achieved; a gear box is adopted to distribute mowing and flattening power; and a gear set is adopted to carry out power transmission of two chipper discs and matching of directions of rotation.
