The invention provides an arrangement structure of a stacker device. The arrangement structure of the stacker device comprises stacking devices, fetching devices, stacking device traveling tracks, fetching device traveling tracks, material input conveyors, material output conveyors, a bedding plant and a closed material storage shed, wherein the stacking devices and the material input conveyors are located on the inner sides of the fetching devices; the fetching devices are across the stacking devices and the material input conveyors. The stacking devices and the material input conveyors penetrate through the internal space of the fetching devices, and the arrangement mode that machine frames of the fetching devices are across the stacking devices, so that the interference problem caused when traveling platforms of the stacking devices are as high as upper traveling platforms of the fetching devices is solved. The upper walking platforms of the fetching devices do not need to be independently arranged; the traveling devices are more convenient to maintain; meanwhile, material pile volume loss caused in order to elude upper traveling platforms of fetching devices in the existing process arrangement mode is avoided, the utilization rate of the internal space of a stockyard is increased, the civil engineering quantity is reduced, economic benefits are remarkable, and great engineering application value is achieved.

The invention discloses a forklift with a cab capable of overturning forwards and a method for reducing the height of container loading of the forklift. The forklift comprises the cab and a frame. The cab can be connected with the frame in a forward overturning manner. The forklift further comprises a limiting mechanism which is detachably arranged between the cab and the frame when the cab overturns forwards to reduce the height of the cab, and therefore the cab can be limited when the cab overturns forwards to a preset angle. During container loading, the cab of the forklift overturns forwards to the preset angle, so that the overall height of the forklift is reduced to a proper height for container loading, and the limiting mechanism is used for limiting the cab so that the cab can be kept in the state of overturning forwards to the preset angle. When the forklift is used for container loading, the height of the forklift can be smaller than the height of common containers so that container loading can be convenient, and therefore when the forklift departs, the cab of the forklift does not need to be completely demounted, the common containers are adopted, and the time and cost of forklift departing are greatly saved.

The grass mower includes a front wheel unit having a left front wheel and a right front wheel which are mounted to a vehicle body frame, a rear wheel unit having a left rear wheel and a right rear wheel which are mounted to the vehicle body frame and a mower unit disposed between the front wheel unit and the rear wheel unit downwardly of the vehicle body frame, the mower unit including a rotary blade unit that has at least a left blade and a right blade which are disposed side by side in a vehicle body left / right direction. The rotary blade unit is configured such that a tread-on track of the left front wheel is overlapped with a rotation locus portion of the left blade from the front side to the rear side thereof and a tread-on track of the right front wheel is overlapped with a rotation locus portion of the right blade from the front side to the rear side thereof.

The invention discloses an electromotor for realizing stator sealing and rotor opening ventilation manners by adopting axial flow ventilation. An adopted shaft is provided with an external circumference spiral groove and is matched with an axial flow fan with two ends clinging to each other and same spiral direction so as to form an axial flow combination ventilation device; the devices are arranged on the inner part of a rotor and two ends of the rotor so as not to occupy an extra motor axial space, so that the electromotor is compact in structure; due to different steering directions, the air flow direction is also different, but the motor can be cooled; by matching with labyrinth seal, a cooling manner combining stator seal type ventilation cooling with rotor open type ventilation cooling of the electromotor is realized, so that the stator insulation reliability and the rotor heat radiation capacity are ensured through the combined cooling manner, and the motor efficiency is improved; a stator cooling air flue is formed by (2x), (2h) and (6h); a rotor cooling air flue is formed by (5y), (9b), (4b) and (10b); the two cooling air flues are connected with each other in series and is jointly supplied with air pressure by the spiral combination device.

The invention discloses a power cabinet convenient to maintain. The invention belongs to the technical field of power maintenance, according to the invention, a rain guide cover is arranged at the topend of a cabinet bin; the cabinet bin is movably connected with a cabinet door through a rotating shaft; a plurality of uniformly distributed fixing plates are arranged on the inner wall of the cabinet bin; each fixing plate is provided with a plurality of uniformly distributed pulleys, the pulleys are movably contacted with a chute, the chute is fixed on a support column, one side of the supportcolumn is provided with a vertical placing plate, and the other side of the support column is provided with a plurality of uniformly distributed transverse placing plates. According to the power cabinet convenient to maintain, equipment in the power cabinet can be conveniently pulled out by means of the push-pull device, and maintenance personnel can complete maintenance tasks more easily.
