Tri-shaft planet frame-paddle type agitator

Abstract: The utility model relates to a tri-shaft planet frame-paddle type agitator, which is characterized by comprising a main shaft, paddle blade agitating shafts, a central gear, a lower bearing chamber, a planet gear, an upper bearing chamber, a frame type agitating paddle blade, agitating paddle blades and an agitator body. The lower bearing chamber is arranged at the bottom inside the agitator body. The upper bearing chamber is arranged on top of the agitator body. The main shaft is arranged between the upper bearing chamber and the lower bearing chamber. The frame type agitating paddle blade is arranged on the main shaft, and the central gear is arranged at the upper end of the lower bearing chamber. Planet gears are arranged at two ends of the central gear, and planet gears are provided with the paddle blade agitating shafts penetrating the bottom edge and the top edge of the frame type agitating paddle blade. The agitating paddle blades are arranged on the paddle blade agitating shafts inside the frame type agitating paddle blade. The main shaft drives the frame type agitating paddle blade to rotate, and the planet gears drive the paddle blade agitating shafts to agitate the materials. Speeds and directions of rotation of the frame type agitating paddle blade and the paddle blade agitating shafts are different so that the rotation is even and comprehensive.

Apparatus for mechanically sorting fruit

Abstract: A paddle mounted on a fruit sorter at the end of a fruit conveyor is connected to the plunger of a solenoid which normally is actuated to bias the paddle into the path of fruit being discharged from the conveyor toward a good-fruit discharge conveyor. A color sorter is positioned to scan the fruit leaving the conveyor, and means are provided to de-energize the solenoid upon the detection of a good fruit to allow the paddle to be moved from the path of the fruit so that the fruit will fall onto the discharge conveyor. Power to operate the solenoid is provided by a circuit which develops a relatively large value of current upon initial energization of the solenoid. This large current acts to quickly move the paddle into the path of any cull fruit or non-fruit leaving the conveyor to deflect such items from the discharge conveyor. The sorter circuitry provides a much smaller amount of current after the initial surge to retain the paddle in its deflecting mode until a good fruit is again scanned. When the solenoid is de-energized its travel is limited by a soft spring so that its return to the deflecting position will be rapid, said spring being readily yieldable if the paddle is hit by a good fruit moving toward the discharge conveyor.

Exercise methods and apparatus simulating stand-up paddle boarding

Abstract: An exercise apparatus includes a frame; a platform configured to receive a person in a standing position, the platform connected to the frame; a handheld component configured to be held by a person standing on the platform; and an impeller-driven fluid circulation system. Manipulation of the handheld component by a person standing on the platform results in driving of the impeller and circulation of fluid within the fluid circulation system. The platform may rock from side to side, whereby a person standing on the platform must maintain balance while manipulating the handheld component. The handheld component may simulate a paddle and may include an elongate shaft. In this respect, the paddle component is used by a person standing on the platform as if the paddle component were a paddle used in paddleboarding, including manipulating the paddle component through a rowing motion that preferably would be experienced when actually paddleboarding.

Devices for blending materials and bags and for use in such devices

Abstract: A device for blending materials and a bag for use in such devices. The device has at least one paddle (5) for acting on a sample and a carrier (2) against which a sample may be crushed by the paddle. The device is arranged to allow adjustment of the spacing between the paddle and carrier during operation. The bag (30) is suitable for use in such a device but can be used in other devices.

Golf-swing training device

Abstract: A golf-swing training device that comprises a club shaft, one end having a grip and the other end having a generally U-shaped member to which a removable flat paddle is attached. The paddle consists of a generally rectangular structure, approximately 1 foot wide and 4 inches tall, featuring a pair of apertures and a retaining channel on one side for cooperative engagement with the generally U-shaped end of the shaft. The training club is swung like a standard club and used to simulate striking a ball with a square face without the use of a golf ball. Because of its size, the paddle provides a visible indication of the position of the club in the hands of a user, allowing immediate adjustments to be made in the course of the swing. In addition, the drag created by the paddle during the downswing results in a force that requires greater effort on the part of the user than a regular club would demand, which in turn strengthens the muscles used to square the face of the club during the downswing. Weight attachments are also provided to increase the mass of the training club for different levels of exercise.
