The invention provides a bionic crocodile robot for detection, the main body of which is composed of a torso, head, feet, tail, anesthesia, claws, etc. The torso includes: a torso upper cover, a torso body, a back cover, etc.; The head part includes: upper jaw, lower jaw, camera, etc.; the foot part includes: thigh, calf belt, thigh connection, etc.; the tail part includes: tail turntable, tail section, tail shaft, etc.; the anesthesia part includes: transposition, launch turntable, anesthesia needle etc.; the claw part includes: lifting blocks, rotating claw discs, grippers, etc.; when in use, the robot walks through the foot part, the head part attacks when necessary, the camera in the head part observes the environment, and the laser radar in the torso part The environment is detected. When danger is encountered, the anesthesia part shoots dangerous creatures. When it is necessary to take the animal's eggs, the claw part is used to grab the eggs.

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 door lock opening mechanism for an anti-theft door, comprising: a door lock panel; a box body; a slide plate, the slide plate is arranged on a side of the box body away from the door lock panel; a drive unit, the The driving unit is arranged in the assembly cavity, and the driving unit includes a bearing seat, a rotating shaft, a first bevel gear, a second bevel gear, a third bevel gear, a fourth bevel gear, a first connecting rod, a rocker arm, first roller, wedge, second link, second roller, first leg, second leg, third leg, fourth leg, tie rod, first spring, second spring, and locking plate . Compared with the prior art, the present invention realizes the opening and closing function of the lock body by setting a new type of door lock opening mechanism by sliding the slide plate. The unlocking mode can enrich the product line, and in the prior art, criminals pull down the handle through the peephole. The unlocking mode of the present application also has the function of preventing criminals from opening through the peephole.

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.
