The invention discloses a novel feed mixing device. The novel feed mixing device comprises a box body, an illuminating device body is fixedly connected to the end face of the top of the box body, a first cavity is formed in the box body, a second cavity is formed behind the first cavity, and a first rotary groove communicated with the second cavity is formed below the first cavity; a third cavityis formed below the first rotary groove, a sliding groove communicated with the first cavity is formed below the first cavity, penetrates through the first rotary groove, and is communicated with thethird cavity, a sliding box is slidably and cooperatively connected with the interior of the third cavity, a fourth cavity is formed in the sliding box, and a fifth cavity is formed below the third cavity. The novel feed mixing device is simple in structure and convenient to operate; meanwhile, the working efficiency and effect of the mixing device are improved.

The objective is to prevent noise of a small pump and improve performance of the small pump. Recess grooves 19, 19..., 20, 20..., 21, 21... or hollows 22, 22..., 23, 23... are scored on an intake valve element 8 opening and closing an intake valve part V1 of the small pump 1 or an upper surface of a rocking body 6 pressed against a back surface of the intake valve element to reduce contact area of the intake valve element 8 and the upper surface of the rocking body 6. Consequently, adhesion of the intake valve body 8 and the rocking body 6 is prevented to reduce noise at a time of open and close of the intake valve element 8.

The invention discloses a thermal forming product frame for producing cemented carbide. The thermal forming product frame for producing the cemented carbide comprises a plate body and a containing cylinder, wherein the containing cylinder is arranged in the plate body in an embedded mode, the bottom wall of the containing cylinder is provided with a first protrusion part, and the side wall of thecontaining cylinder is provided with second protrusion parts; the second protrusion parts are uniformly arranged along the side wall of the containing cylinder in a spaced mode; air vent holes are formed in the second protrusion parts; the plate body is provided with ear parts and supporting feet; bending parts are arranged at the tail ends of the supporting feet, and containing grooves are formedin the top walls of the ear parts; sliding grooves are formed in the side walls of the ear parts, sliding pieces are matched with the sliding grooves, handles are hinged to the outer ends of the sliding pieces, and the handles are provided with abutting blocks; opening parts of the sliding grooves are provided with an extending plate arranged parallel to the plate body; when the sliding pieces are positioned at first sliding stop points, the sliding pieces are completely contained in the sliding grooves, the extending plate is attached to the handles, and the bending parts abut against the containing grooves through an abutting plate; and when the sliding pieces are positioned at second sliding stop points, the handles are separated from the extending plate to relieve the locking on the abutting blocks. According to the thermal forming product frame for producing the cemented carbide, the loading capacity is large, blanks can be protected effectively, and the thermal forming efficiency can be further improved.
