The invention discloses a new energy automobile driving motor protection shell which comprises a shell mechanism, a damping mechanism, a heat dissipation mechanism and a waterproof mechanism, wherein the damping mechanism is located in the shell mechanism, the heat dissipation mechanism is located in the shell mechanism and on the outer wall of the shell mechanism, and the waterproof mechanism is located in the heat dissipation mechanism. When the protection shell is impacted, under the action of inertia, the inner shell is slidably connected to the outer surface of the motor in a sleeving mode, a second layer of protection is provided for the motor, meanwhile, during normal running, the inner shell slides back to the original position, the inner shell is slidably arranged, the flexibility of the device is improved, in the normal running process of the motor, the inner shell does not provide secondary protection for the motor, and heat dissipation of the motor and normal operation of the motor are facilitated. The device can provide double-layer protection for the motor, the outer shell protects the motor, the inner shell reduces impact force generated by collision, the motor is buffered, damage to the motor is prevented, and the device is suitable for various motors of different sizes.

The invention relates to the technical field of preparation of lead tetraoxide, and discloses an energy-saving preparation device of the lead tetraoxide. The device comprises a material conveying boxbody, and an integrated material conveying and heating mechanism is arranged inside the material conveying box body, the integrated material conveying and heating mechanism comprises a motor protection cover, a first motor, a first motor shaft, a first electric heating pipe, spiral blades, an electric sliding ring, a first connecting pipe, a second connecting pipe, a rotary connector, a heating box body and a fixing plate. According to the device, the electric heating pipes penetrate the interiors of the material conveying box body and the heating box body, the surfaces of the electric heatingpipes are provided with the spiral blades and rollers, so that the interiors of the material conveying box body and the heating box body can be heated at the same time through the first electric heating pipe, lead materials inside the material conveying box body can be preheated, heating time of the lead materials inside the heating box body is saved, the spiral blades and the rollers can be driven to rotate in a rotating process of the first electric heating pipe, meanwhile, material conveying is conducted, the rollers are used for stirring the lead materials, and the lead material heating uniformity effect is improved.

The invention belongs to the technical field of biology, particularly relates to a sample post office, and aims at solving the technical problem that exponential reduction of scientific and medical research values is finally caused by various problems that precious specimens are accidentally scrapped due to repeated freezing and thawing of existing biological specimens and the like. A motor protection bin is formed in one side of the motor set, a driving motor is installed in the motor protection bin and fixed to a motor installation plate, the bottom of the motor installation plate is fixed to the top of the body base plate, a plurality of air pipe connectors are fixed to the outer wall of the body base plate at equal intervals, and a rotating assembly is installed at the bottom of the body base plate. A first synchronous belt wheel is fixed to an output shaft of the driving motor, a second synchronous belt wheel is arranged on the top of the body base plate, and the second synchronous belt wheel is meshed with the first synchronous belt wheel. According to the invention, high efficiency of information and scientific research achievement conversion can be fully ensured while safe storage of biological samples is fully ensured, so that conversion of scientific research achievements is assisted.

The invention relates to the technical field of woodworking mechanical equipment, in particular to a board multi-blade saw sorting machine. A board cutting multi-blade saw comprises a rack (1) and is characterized by further comprising foot stands (2), a working table (3), a speed-reducing motor (4), connecting blocks (5), adjusting switches (6), a main transmission shaft (7), a material pressing shaft (8), a transmission chain wheel set (9), a motor protection cover (10) and a pressing wheel cover (11). The board multi-blade saw sorting machine has the beneficial effects that the board multi-blade saw sorting machine is connected with a board multi-blade saw device, battens subjected to cutting correspond to the width of the sorting machine, the thickness of the material pressing shaft is adjusted through the adjusting switches, the multi-blade saw and the sorting machine are synchronously started, and transmission sorting can be achieved; in this way, not only is the labor cost reduced, but the production efficiency is improved.
