The invention discloses a quantitative rice discharging device of an intelligent rice storage bucket. The quantitative rice discharging device of the intelligent rice storage bucket in the invention comprises a rice outlet pipe, a rotating shaft, a stepping motor, a controller, an electric button and a power supply; the rice outlet pipe is vertically arranged; furthermore, the top of the rice outlet pipe is communicated with a rice outlet; two ends of the rotating shaft are rotatably connected with the side wall of a rice bin; furthermore, the shaft body of the rotating shaft is fit to the edge of the pipe mouth at the bottom of the rice outlet pipe; a radial through hole is formed in the shaft body of the rotating shaft; the through hole is communicated with the rice outlet pipe; the stepping motor is fixed on the inner wall of the rice bin; furthermore, the power output shaft is connected with one end of the rotating shaft; the controller is fixed on the inner wall of the rice bin, and electrically connected with the stepping motor; the electric button is arranged on the outer wall of the rice bin, and electrically connected with the controller; and the power supply is respectively connected with the stepping motor and the controller electrically. According to the quantitative rice discharging device of the intelligent rice storage bucket in the invention, rotation of the rotating shaft is controlled, so that closing and opening of the rice outlet pipe are realized; the rice outlet amount can be controlled by controlling the starting time; operation is simple; the controleffect is good; the rice discharging amount can be precisely measured; and starting is convenient.

The invention relates to an unlocking key of a mechanical digital lock. The variable-code key with cylinder shifting teeth is characterized in that: a key rod is provided with multiple shifting tooth holes; the cylinder shifting teeth are mounted in partial or all shifting tooth holes, freely stretch / withdraw relative to the shifting tooth holes, and can switch in different shifting tooth holes; and only one cylinder shifting tooth can be mounted in the shifting tooth holes on the same circumference of the key rod. With a simple structure, the variable-code key provided by the invention not only realizes the intrinsic locking / unlocking function of a key, but also can change the combination of the cylinder shifting teeth and the shifting tooth holes on different positions of the key; and moreover, a novel key component integrating the encryption function and the key locking / unlocking function is created, two simple and convenient cylinder shifting tooth structures are provided, and more other cylinder shifting teeth with the same concept are also applicable. The variable-code key is simple to operate, convenient to use and high in security and suitable to be matched with the concealed digital locks of various safety boxes and security doors.

The invention discloses a garbage classification device for kitchen garbage for large-scale catering. The garbage classification device comprises a heating tank, a separation cavity is formed in the heating tank; a portal frame is fixedly arranged on the upper side end surface of the separation cavity; the gravity action in vertical and horizontal states is different from the elastic force direction of the spring in reverse direction, the opening and closing functions of the valve are realized; therefore, the food residues are separated from oil and water; intermittent rotation is realized through a grooved wheel structure to discharge food residues; besides, the grease and the water are separated by utilizing different chemical properties and different melting and boiling points of the grease and the water and evaporation of the water during heating, and the heating of oil-water mixed liquid is accelerated by rotating the stirring rods which can be close to or far away from each other, so that the work of automatically and timely separating the kitchen waste is realized.
