By means of the equipment, the anchoring efficiency can be matched with the drivage efficiency, and the comprehensive drivage-anchoring efficiency is promoted.

The invention discloses a powder coating pulverizer. The powder coating pulverizer comprises a rack, a vibration conveying device, a distributing device and a smashing device. The powder coating pulverizer can conduct distributing on powder stock before smashing is conducted, and full smashing on the powder stock can be achieved.

The invention discloses a riding-type rice seedling transplanting machine, which is characterized in that a planting device is arranged below the middle part of a machine body between a front wheel and a rear wheel, a rice seedling pressing device is installed above the planting device, a rice seedling carrying platform is connected above the rice seedling pressing device, a rice seedling supply part above the rice seedling carrying platform is obliquely connected with the rice seedling carrying platform, a rice seedling tray is conveyed to the rice seedling pressing device from the rice seedling supply part through the rice seedling carrying platform, a conveying roller is arranged at the rice seedling supply part, the conveying roller is provided with convex teeth, and a rice seedling pressing plate which is used for pressing the edge of the rice seedling tray towards the conveying roller is arranged on a guide wall plate corresponding to the rice seedling supply part above the conveying roller. By downwards pressing the rice seedling tray through the rice seedling pressing plate to be matched with the conveying roller for conveying the rice seedling tray, since no many conveying rollers are used, the structure is simple, the cost is reduced and the maintenance of the machine is facilitated; and when the rice seedling tray is taken out, even though the rice seedling tray is at the positions of the rice seedling supply part and the rice seedling carrying platform, the rice seedling tray can be rapidly and conveniently taken out without conducting any other operation.

The invention discloses a message order preserving method based on a serial number mechanism, which comprises the following steps that: S1, when asynchronous message sending operation is carried out each time, a sending end packages a current sending serial number into a packet header, and adds 1 to the sending serial number; S2, a receiving end compares the current receiving serial number with the sending serial number carried in the packet header every time the receiving end successfully receives the asynchronous message; S3, after the message requests arriving in sequence are successfully processed, 1 is added to the value of a message serial number generator at the receiving end, and whether elements matched with the current receiving serial number exist in the elements arriving in a out-of-sequence queue or not are determined; and S4, if it is determined that the asynchronous message arrives out of order once, the message buffer area which finishes receiving this time is added into an out-of-order arrival queue, and processing is performed after the subsequent message arrives and the receiving serial number is updated. Concurrency of communication paths can be effectively guaranteed, the problem of message sequences caused by a bottom-layer interconnection framework can be effectively solved, and meanwhile influences of serial number generation and matching on performanceare very low.

The present invention relates to a rotary piston 10 for a rotary piston pump, wherein the rotary piston 10 comprises at least one supporting body 12, through which the axis of rotation D of the rotary piston 10 extends, and at least one end cap portion 14, 16 which is arranged radially outwards of the at least one supporting body 12 and is connected flexibly, preferably elastically, to the at least one supporting body 12.

The invention relates to a bagging system for a sponge inner sleeve. The bagging system comprises a feeding unit, a bagging unit, a cutting and overseam unit and a discharging unit sequentially arranged. The bagging system has the following advantages: through mutual cooperation of the feeding unit, the bagging unit, the cutting and overseam unit and the discharging unit, automatic conveying and bagging of sponge and automatic cutting and overseam unit of a yarn bag are realized, manual labor is greatly reduced during the entire process, effectively saves the labor force and correspondingly improves the working efficiency.

The invention relates to a grass grid sand barrier grass roll continuous laying device which comprises a vehicle body, a ditching wheel, a grass pressing wheel and a gathering device are arranged at the lower end of the vehicle body and are sequentially arranged in the advancing direction of the vehicle body, a traction wheel set and a continuous feeding device are further arranged on the vehicle body, and the continuous feeding device comprises a first rotating wheel and a second rotating wheel. The traction wheel set is arranged below the position between the first rotating wheel and the second rotating wheel, the first rotating wheel and the second rotating wheel are each provided with a plurality of storage bins in the circumferential direction, the storage bins are used for containing grass rolls, the side walls of the storage bins are provided with notches used for discharging grass roll stub bars out of the bins, and the first rotating wheel and the second rotating wheel rotate to the discharging position in turn so that grass can be connected. The traction wheel set is used for pulling straw roll stub bars, and the problem of continuous conveying of straw rolls of the straw grid laying device is solved.

The invention discloses an asynchronous underwater full-rate cooperative communication method. The method includes the following steps that first, a source node acquires the right to use a channel and sends data; second, when the number of relay nodes capable of being used in the current transmission is larger than or equal to two, a full-rate cooperative communication mode is started; third, the relay nodes capable of being used are divided into N groups, the relay nodes in all the groups monitor data frames sent by the source node, when the nth group of relay nodes monitor the ith frame of data, if the remainder generated by dividing i by N is n, the group of relay nodes receive the frame of data, and if not, the monitoring is continued; a target node receives the data frames sent by the source node and the data frames forwarded by all the groups of relay nodes; after data transmission of the source node is completed, a stop signal is sent, the relay nodes receive the stop signal, forward the stop signal and then stop relay transmission, and the target node stops receiving after receiving the stop signal. The method has the advantages that the transmission rate is improved, and cost and power consumption are low.
