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 buffering fishway and a buffering method suitable for emergency flood discharge with reduced damage. The buffering fishway includes a fishway body, and a migratory channel is arranged in the fishway body, and one end of the fishway body rotates with a fixed seat. The other end is connected to the counterweight floating dock in rotation, and a plurality of swingable buffer plates are hinged in the migratory channel; in addition, the present invention also discloses a corresponding buffer method; the present invention can reduce the potential energy of floods and reduce the impact on The impact force caused by the fish can effectively avoid the phenomenon that the fish in the fishway are easily injured by the violent impact of the flood when the sluice dam discharges the flood, and has a high protection effect on the fish.

The invention relates to the field of medical equipment, in particular to an initiative control type hand-cranking traction bed and aims to solve problems of low user friendliness in a treatment process and poor treatment effects caused by the fact that patients can only passively accept traction treatment instead of initiative control in use of existing traction medical equipment. The initiativecontrol type hand-cranking traction bed comprises a headrest platform, an upper body platform, a hip plate, a lower limb platform, a frame and a bed body guide rail. The headrest platform is hinged tothe upper body platform, the upper body platform is movably connected with the hip plate through rotating shafts on two sides of the hip plate, the hip plate is fixedly mounted on the frame, and thelower limb platform is arranged on the bed body guide rail. The headrest platform has a horizontal bilateral swing degree of freedom relative to the upper body platform, the upper body platform has avertical turning degree of freedom relative to the hip plate, and the lower limb platform has a longitudinal moving degree of freedom relative to the lower limb platform. By the initiative control type hand-cranking traction bed, initiative cervical vertebra, lumbar vertebra and vertebral column traction treatment of patients can be realized.

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.
