The invention provides an earphone storage box, and belongs to the field of storage devices. The earphone storage box comprises a disc-shaped box body and a disc-shaped cover body, wherein the box body is detachably connected with the cover body, and can rotate relative to the cover body; a turntable is arranged in the box body, and comprises a partition plate and a rotating shaft passing through the axis of the partition plate; a connecting part capable of fixing an earphone wire is arranged on the partition plate, and the earphone wire can pass through the connecting part; an upper shaft sleeve detachably connected with the rotating shaft is arranged on the inner side of the cover body, and the rotating shaft can be driven by the upper shaft sleeve to rotate; a lower shaft sleeve detachably connected with the rotating shaft is arranged in the box body, and can rotate relative to the rotating shaft; two through holes through which earphone jacks can pass are formed in the side part of the box body. According to the earphone storage box, the earphone wire can be conveniently and rapidly reeled and unreeled without intertwining, and ideal wire arrangement effects are achieved.

The invention discloses a fault-tolerate primary permanent magnetic vernier linear motor, which is applied to the field of high-reliability linear driving and comprises a primary winding, a secondary winding and an armature winding; the secondary winding is a simple salient pole structure with ladder-shaped teeth and is longer than the primary winding, an air gap exists between the primary and secondary windings, armature teeth with even number are uniformly distributed on the primary winding, a set of concentrated winding is wound on each armature tooth, a fault-tolerate tooth is arranged between adjacent two armature teeth, a permanent magnet with the magnetizing direction being parallel to the central symmetrical axis of the armature is attached to the lower face of each armature tooth, the permanent magnets are uniformly distributed on each armature tooth, the magnetizing direction of each permanent magnet is in N-S and S-N alternative arrangement, and the magnetizing directions of the permanent magnets on all armature tooth are same in arranging sequence; and the height of the fault-tolerate tooth is equal to the sum of the heights of the armature tooth with the face being attached to the permanent magnetic and the permanent magnet. The fault-tolerate primary permanent magnetic vernier linear motor is simple in structure, large in pushing force, small in pushing force pulse, high in reliability and strong in the running property of the motor with the fault and fault-tolerate property.

The invention discloses a multifunctional garlic combine harvester, which comprises a power locomotive, a transmission system, a clamping, pulling and conveying system, a positioning and cutting system, a rack and a control device. The multifunctional garlic combine harvester is characterized in that the harvesting of garlic which is planted at different line spacing in different terrains is realized through twirling, extension, retraction and translation of the rack, the multifunctional garlic combine harvester adapts to lands with different softness and humidity and viscosity by using a sleigh plate to limit depth, the depth is stably limited and the situation of twisting is avoided; the clamping, pulling and conveying system realizes pulling, closing, steering and horizontal included angle adjustment, and good preparations are made for high-efficiency cutting; the positioning and cutting system accurately positions and precisely cuts garlic bulbs according to a geometric principle that the position of a base cutting point is always unchanged when an isosceles triangle is tangent with circles or ellipses with different sizes because the base angle of the isosceles triangle is fixed and the side length of the isosceles triangle is variable; the transmission system transmits needed power by using a retractable transmission shaft, a steering gearbox, a universal joint and the like; and the most common agricultural motor tricycle can be used as the power locomotive to reduce the cost. The multifunctional garlic combine harvester has the advantages of novel design, compact structure, complete functions and high adaptability.

The invention provides a six-phase isolated permanent magnet motor. The six-phase isolated permanent magnet motor comprises a shell, a permanent magnet, stator cores, a rotor core, armature windings and a shaft; 12 pairs of L-shaped stator cores are fixed in the shell; convex stator poles are at the inner side of the stator cores; the permanent magnet is clamped between the two stator cores, so that a pair of stator cores can be formed; two stator poles on a pair of stator cores are parallel; each stator pole is wound with the centralized armature windings; the armature windings of the two poles on the same pair of stator cores are opposite in winding direction and same in phase; the various armature windings in the circumference direction are divided into six phases according to different phases; 22 uniformly distributed convex poles are on the rotor core; and the 22 uniformly distributed convex poles and 24 stator poles form a 24 / 22-pole structure. The six-phase isolated permanent magnet motor provided by the invention has six-phase windings; after one phase is failed, various other phases can operate continuously; furthermore, the rotor is simple in structure; the rotor does not have a winding; and the mechanical strength is high.
