The invention provides a servo cleaning device and method for an automotive body painting production line. Servo spray washing is carried out on an automotive body after the phosphating treatment, thereby greatly reducing residual phosphating liquid on the upper surface of the automotive body. Furthermore, during the process when the phosphating liquid is transferred from a phosphating slot to a washing tank, the probability of excessive reaction happening between the residual phosphating liquid and the automotive body can be reduced, thereby improving the once qualified rate of products and reducing the reworking and repairing cost of the automotive body. The servo cleaning device for the automotive body painting production line has the advantages of being adapt to car models of different height and achievable in automatically setting the height of nozzles, thereby making the automotive body sprayed more uniformly. Maintaining a reasonable distance, water can be saved while the residual phosphating liquid can be removed. Blowing is carried out on the automotive body after being sprayed, and drops of water on the surface of the automotive body can be removed, thereby preventing the residue of the phosphating liquid. The automotive body can move back and forth along with a horizontal transmission mechanism, thereby ensuring the uniformity of the spraying and blowing operation. Forward, backward and forward again, the spraying and blowing operation should be completed two times and there are no extra steps, thereby reducing the process cost.

The distance-weighting-based routing algorithm disclosed by the invention calculates a reasonable wireless communication distance through weighing calculation so as to display a relative distance between two nodes more accurately; in a GPS position aid-based distance forwarding protocol, the technology is used more reasonably; and a more accurate distance can enable a Mesh network to forward a more accurate correctness forwarding message.

The invention discloses a seed piece unit which is characterized by comprising a fiber layer and a nutritive water-absorbing layer from top to bottom, wherein seeds are arranged between the fiber layer and the nutritive water-absorbing layer; and the nutritive water-absorbing layer comprises a nutrient layer and a water absorbing material layer. According to the seed piece provided by the invention, the seeds can be uniformly spread, and the fiber layer can enable the seeds to meet appropriate resistance during growth while providing nutrients for the seeds, so that the seed growth is healthyand strong; since the nutritive water-absorbing layer comprises the nutrient layer and the water absorbing material layer, fertilization of a planter is not needed, only the seed piece needs to be arranged in a place close to water, the operation is convenient and rapid, and the germination rate of the seeds is increased.

The invention discloses a toppling-prevention drawer chest which comprises a chest body, drawers and supporting foot driving assemblies. The supporting foot driving assemblies are used for driving supporting feet to act. Any layer of drawers is provided with a connecting rod limiting device and an elastic convex block, and when the drawers are opened, the connecting rod limiting device on the layer of drawers can drive the supporting feet to extend out of the chest body; when the drawers are closed, and the finally closed drawers control retraction of the supporting feet through the elastic convex blocks. The toppling-prevention drawer chest achieves that any layer of drawers can control out-drawing of the supporting feet, the out-drawing distances of the supporting feet are controlled bythe drawers having maximum out-drawing distances; when the drawers are closed, the finally closed drawers flexibly control the supporting feet to retract through the elastic convex blocks.

The invention belongs to the field of material delivery and particularly relates to a mining anti-impact rotating plate feeding machine. The feeding machine comprises a material guide groove and further comprises a rotating plate device which comprises a rotating lifting mechanism and a rotating plate. The material guide groove is directly connected with a bunker port, the rotating plate device is arranged in the material guide groove and avoids the feeding end of the material guide groove, the rotating plate device is hinged with the material guide groove, one end of the rotating plate is hinged with the material guide groove, and the rotating lifting mechanism drives the other end of the rotating plate to be lifted.
