A portable rebound (or deflecting) sports training device having at least a first rebound panel or surface adapted to rebound a ball away from the device, and a support structure adapted to hold the panel in a first, operational condition in which the panel is held generally upright; the panel and the support structure having a second, transport or storage, configuration relative to each other such that the panel and support structure lie flatter (or generally flat) relative to each other in the direction transverse to the rebound panel such that the device occupies less space.

The invention relates to a construction waste steel bar reprocessing device. The construction waste steel bar reprocessing device effectively solves the problems related to steel bar daubing cement, rust removal and the like; the technical proposal is to include a shell, wherein the left side of the shell is provided with a steel bar propelling device and a guide cylinder, a sleeve which is coaxial with the guide cylinder and can rotate is arranged inside the shell, a planetary gear set is arranged at the left end of the sleeve in a sleeved mode, the outer gear ring of the planetary gear set is fixedly connected with the shell, and a sun gear of the planetary gear set is arranged on the sleeve in a sleeved mode; the sleeve can drive the sun wheel to rotate, a plurality of sector-shaped rust removal brushes are uniformly distributed on the circumference of each planetary gear of the planetary gear set, a water storage tank which is positioned on the right side of the planetary gear setis fixedly arranged inside the shell, the right end of the sleeve is not in contact with and is arranged inside the water storage tank, the plurality of radial connecting rods are uniformly distributed on the circumference of the right end of the sleeve, and the other end of the connecting rods are connected with a scraper. The construction waste steel bar reprocessing device is not only convenient for rust removal but also conducive to coating cement.

The invention relates to a turning control method, a device, and a mixer truck. The turning control method is used for the mixer truck. The mixer truck comprises a tank body. The turning control method comprises following steps: in turning of the mixer truck, the practical turning direction of the mixer truck is obtained; a target rotating speed of the tank body is determined based on the practical turning direction and the stirring direction of the tank body; the tank body is controlled to rotate at the target rotating speed along the stirring direction, so that in turning of the mixer truck,automatic adjusting of the rotating speed of the tank body is realized based on the relationship of the practical turning direction of the mixer truck and the stirring direction of the tank body, dependent on single speed reduction by drivers is avoided, the stability and driving safety of the mixer truck are improved, driver labor intensity is reduced; and in addition, the mixer truck is more stable, so that excess wearing caused by aggressive vibration is avoided, and the service life of the mixer truck is prolonged.

The invention discloses a device for controlling temperatures of a pole sole of a magnetic track brake and a track as well as a control method thereof. A first non-contact temperature sensor and a second non-contact temperature sensor are respectively used for detecting the temperature of the pole sole of the magnetic track brake and the steel track; a water through hole is formed in the side face of the pole sole of the magnetic track brake; small water spraying holes are formed at the bottom of the pole sole of the magnetic track brake; the water through hole and the small water spraying holes are communicated inside the pole sole of the magnetic track brake; the water through hole is connected with the lower part of a water tank in a sealed manner by passing through a spiral elastic hose and a first solenoid valve in sequence; a liquid meter is arranged in the water tank; the top of the water tank is communicated with atmosphere through a second solenoid valve; the side part of the water tank is connected with a water pipe connected on a train through a fourth solenoid valve; the side part of the water tank is sequentially connected with an air duct on the train through a one-way valve and a third solenoid valve in sequence; and the liquid meter and the solenoid valves are connected with an electronic control unit. The device provided by the invention can effectively cool the pole sole and the steel track, so that the excessive abrasion and the adhesive welding of the pole sole and the steel track can be prevented when the magnetic track brake works.

The invention relates to the technical field of pipe processing equipment and discloses anticorrosive paint spraying and grinding equipment for production and processing of a buried pipe. The anticorrosive paint spraying and grinding equipment comprises a machine table; supporting legs are fixedly installed at the bottom end of the machine table; fixing rods are fixedly installed at the top end ofthe machine table; the top ends of the fixing rods are fixedly connected with a horizontal plate; a transmission machine is placed on the horizontal plate; the middle part of the transmission machineis fixedly provided with a fixed point grinder in a sleeving manner; a component positioned at the side surface of the fixed point grinder is fixedly installed inside the transmission machine; movingwheels are arranged at the bottom end of the transmission machine; and the moving wheels are matched with fixing grooves which are formed in the top of the horizontal plate. According to the anticorrosive paint spraying and grinding equipment for production and processing of the buried pipe, a transmission driven plate is moved toward a direction corresponding to a screw handle by twisting the screw handle so that two externally connected rods are used for driving two contact plates to expand; by regulating the radian of the two contact plates, material pipes which are different in diameter can be conveniently supported and positioned; and a bearing frame device is used for auxiliary support for the position, thereby effectively guaranteeing processing of the material pipes which are different in length.
