Abstract: A powder bucket and a powder dispensing device are provided. The powder bucket includes a bucket body, a stirring rod, a funnel, and a scraper. The bucket body defines a first accommodating cavity and has a powder outlet in communication with the first accommodating cavity. The stirring rod is rotatable around an axis of the stirring rod, at least partially placed in the first accommodating cavity, and configured to adjust an opening degree of the powder outlet. The funnel has one end connected to the bucket body and the other end having a powder leakage port. The powder outlet and the powder leakage port are both in communication with a second accommodating cavity defined by the funnel. The scraper is at least partially placed in the second accommodating cavity, connected to the stirring rod, and rotatable around the axis of the stirring rod following rotation of the stirring rod.

Abstract: A lower limb training rehabilitation apparatus, comprising a weight reducing device, a pelvis supporting device, an exoskeleton device, a control system for controlling mechanical movements of the rehabilitation apparatus, and a treadmill used for walking of a patient. The rehabilitation apparatus hoists the upper body of the patient by means of the weight reducing device, then fixes the crotch of the patient to the pelvis supporting device, and fixes two legs of the patient to two mechanical legs of the exoskeleton device. A power source drives the pelvis supporting device to move up and down, so that the patient can move in the vertical direction; in addition, a sliding base of the pelvis supporting device can assist the patient in moving left and right, swinging left and right, and twisting. The mechanical legs and the treadmill together implement arbitrary movements in six degrees of freedom of the patient.
