The present invention relates to a seed sowing apparatus which includes a substantially flat circular disc (1) mounted on a frame so as to be rotatable about horizontal axis (2) while partly embedded in soil (3) and drawn in a forward direction substantially parallel to the soil surface and substantially perpendicular to a disc axle. The apparatus also includes at least one blade (10) having a leading edge (11) defined by the intersection of two opposite side surfaces and structure (41, 45) for mounting the blades on the apparatus so that the leading edge (11) is held close to or in intimate contact with the disc (1), wherein the at least one blade's leading edge (11) is inclined in a plane of the blade such that an angle of the leading edge (11) with respect to an arc (A, B, C) of the disc surface passing beneath the leading edge (11) is zero or positive over the entire length of the leading edge (11).

The invention relates to a platinum vessel automatic polishing machine and a method. The platinum vessel automatic polishing machine is formed by a protective cover, a workbench, a machine head, a main motor, a polishing machine fixing shaft, a polishing machine main shaft, a lock head, a polishing head, a lifting control rod, a fixing sleeve, a crucible fixing sleeve, a fixing sleeve motor, a limiter, a driving wheel, a driven wheel and a belt; the main motor is fixed on a rear plate of the protective cover; the driving wheel is fixed on a main motor shaft; the driven wheel is driven by the driving wheel through the belt; the lower end of the polishing machine main shaft is connected with the lock head. The polishing method comprises driving the polishing head by the main motor for forward polishing; controlling the speed of the fixing sleeve motor; performing backward polishing from slow to fast. The platinum vessel automatic polishing machine and the method are suitable for the precise analysis and detection field and the platinum vessel treatment, the operation is simple, convenient and safe, the high cost caused by remelting is saved, the deformation of workpieces after grinding is not produced, the damage to the surface is not produced, the accuracy is not affected, the cost is low, the speed is high, the operation can be achieved in about two minutes, and the working efficiency and the polishing effect are greatly improved in comparison with the manual polishing.

The invention discloses movable mortar production equipment which is characterized by comprising a metering box, a mixing box, a packaging control box and a box body connecting limit member, wherein the packaging control box is located on the ground, and the mixing box is overlapped on the left part of the packaging control box in a manner of mutually overlapping freight containers; the mixing box and the packaging control box are in limit fixed connection through a corresponding box body connecting limit member so that the mixing box and the packaging control box are prevented from misplacing in a horizontal direction, and are fixedly connected through corresponding bolts; the metering box is overlapped on the mixing box in a manner of mutually overlapping the freight containers, and the mixing box and the packaging control box are in limit fixed connection through the corresponding box body connecting limit member so that the mixing box and the packaging control box are prevented from misplacing in a horizontal direction and are fixedly connected through the corresponding bolts.
