The invention provides a multi-size automatic steel pipe cutting machine, which includes a bottom plate, an upper plate, a transmission bracket, a first optical axis, a lead screw slide table, a lead screw, a storage bin, a second optical axis, a pipe retaining bracket, a first feeding Feed support, second feed support, swing cutting unit, feed unit, third servo motor, first feed support plate, second conveyor belt, second feed support plate, feed unit, grasping unit, etc. The taking unit takes and feeds quickly and accurately; the feeding unit is evenly distributed on the circumference of the steel pipe to precisely position the steel pipe; the swing cutting unit can cut the steel pipe continuously and efficiently; the invention greatly improves the processing efficiency of material processing and liberates the labor force.

The invention discloses a robot pick up ball, which relates to the technical field of sports auxiliary equipment, and solves the problem of low efficiency of an existing ball picking tool for ping-pong balls and tennis balls. The ball picking robot comprises an omnidirectional wheel platform, a chassis arranged on the omnidirectional wheel platform, a ball storage box arranged on the chassis, a rotary drum seat arranged on the chassis, a rotary drum connected with the rotary drum seat, a motor arranged on the chassis, a first synchronous belt pulley connected with the motor, a second synchronous belt pulley connected with the rotary drum and connected with the first synchronous belt pulley through a belt, a crank connected with the first synchronous belt pulley, a guide rail arranged on the chassis, a slide block arranged on the guide rail and connected with the crank, a single-chip computer connected with the omnidirectional wheel platform and the motor, and a camera connected with the single-chip computer. The camera shoots images, and the single-chip computer analyzes a position of a ball and controls operations of the omnidirectional wheel platform and the motor, namely controls the rotary drum and the slide block to carry the ball. The ball picking robot has the advantages of high ball recognition speed, high recognition accuracy, large ball picking quantity, high ball picking efficiency, small volume and low cost.

The invention relates to a circuit breaker and its arc extinguishing chamber, its arc contact assembly and arc contact transmission rod. The arc contact transmission rod includes a shift fork and an arc contact for driving the The rod body between the heads, the rod body is provided with a long drive slot for pushing and matching with the push post on the shift fork. The driving groove segment corresponding to the moving stroke has a chute segment inclined to the extending direction of the rod body so that the two ends of the driving groove segment are staggered in the extending direction of the rod body. The two ends of the driving groove section provided by the present invention are arranged staggered in the up and down direction, and the relative movement between the pushing boss and the driving long groove in the up and down direction can be used to effectively improve the moving speed of the arc contact assembly and shorten the The closing time shortens the insulation establishment time and improves the breaking capacity.

The present invention involves a high efficient synthesis jet driver that can produce high efficient synthesis jet by changing the up-down periodic time of driving signal. The driver includes the control system and implements system. The control includes micro-computer, A / D converter card, PLC programmable logic controller. The implement system includes servo motors, the heart crank mechanism, vibrator, and cavity. The control system produces a high drive signal and control and monitors the work of driver. The implement system receives the order that the control system brings up and work according to the order. The introduction of PLC programmable logic controller that can control the operation of electric engine in the control system make the centering crank structure hurry convolution character and shorten the jet blowing process and lengthen the air-breathing process to produce high efficient synthesis jet.

The invention discloses a device suitable for brushing lime water on trees in the field of forestry machinery and a working method thereof. The surface of the trunk is painted with lime water. The crank slider mechanism can realize the up and down movement of the brushing claws. The driving mechanism mainly controls the accurate positioning of the trolley position before painting. The stirring mechanism mainly controls the stirring operation of the lime water and mixes the lime The water is sent to the claw brushing mechanism, and the electromagnet is used to drive the claws in the two sets of claw chains that are staggered in the upper and lower spaces to close together to form a circular surface to embrace the tree trunk. Compared with the spraying method in the prior art, the consumption of lime water can be effectively reduced , to make lime water smear more uniform, suitable for trees with different diameters and irregular trunk shapes to evenly apply lime water, which can save the amount of lime water, and the brushing process is completed by motor drive, which improves work efficiency.
