The utility model discloses a seed tray auxiliary device for improving seeding accuracy of a seedling raising seeder, which relates to the technical field of seedling raising and seeding and comprises a top plate, a bottom plate and L-shaped mounting seats respectively connected to two sides of the bottom plate. The top plate and the bottom plate are respectively provided with a plurality of mounting holes with overlapped projections, and the upper end and the lower end of the telescopic pipe body alignment mechanism are respectively assembled in the corresponding mounting holes. The telescopic driving mechanism drives the sliding pipe to slide upwards in the sleeve, so that the inner cavity of the second conical pipe part covers the outer side of the needle type suction head, seeds are put into the channel of the telescopic pipe body alignment mechanism, interference of external airflow on the seeds in the channel is prevented, and the bottom of the seeds is accurately aligned with a seedling raising tray.

The invention relates to the technical field of light steel profile machining, in particular to automatic light steel profile surface trepanning equipment which comprises a base, an arch frame, a scrap collecting frame, a trepanning drill bit, a power unit, a feeding unit, an abutting mechanism and a clamping mechanism. The arch frame is fixed to the top of the base and used for bearing the groove-shaped light steel and guiding the groove-shaped light steel to move in the length direction. Circumferential rotation is converted into linear reciprocating motion through sliding fit of the follow-up rod and the crank disc, and synchronous feeding of the upper and lower trepanning drill bits in the vertical direction is achieved through linkage of the transmission gear and the double racks. Meanwhile, the abutting plate makes contact with the light steel before the drill bit, the abutting spring is compressed along with feeding of the drill bit to generate uniform abutting force, the light steel is firmly locked to the arch frame, the damper buffers impact force and drilling vibration, shaking of the light steel is effectively restrained through the dual effects, it is ensured that the hole position is accurate, the hole wall is smooth, the force application directions of the drilling drill bit and the abutting plate are opposite, and uneven stress on one side is avoided.

The utility model discloses an elevator button convenient to installation, including character piece, transmission part, outer frame, elastic pad, circuit board and fixing piece, the top of transmission part is equipped with first placement groove and character piece is installed in first placement groove, the bottom of transmission part is equipped with a plurality of direction's away from the clamping piece and limiting piece of top, clamping piece is equipped with the clamping end, the side of transmission part is surrounded by outer frame, and the inner wall of outer frame is equipped with a plurality of first clamping block and fixed end, the top of clamping end is close to the bottom of first clamping block, and the fixed end is equipped with first fixed hole, the outer wall of outer frame is equipped with first clamping tooth area and second clamping tooth area. The utility model discloses an elevator button convenient to installation, overcomes the inconvenient installation and dismounting of existing elevator button, and the defect that structure stability is insufficient is not uniform to bad and uneven touch.

This invention discloses a multi-stage drilling trajectory stabilizer, comprising an outer casing and an electric cylinder. An mounting cylinder is fixedly installed on the top of the outer casing, and an auxiliary stabilizing sleeve is fixedly installed inside the mounting cylinder. Two sliding grooves are formed inside the outer casing, and sliding rods are slidably installed inside each of the two sliding grooves. An extension connecting rod is threaded to the top of each sliding rod, and a connecting sleeve is fixedly installed on the top of each sliding rod. The invention employs a dual stabilizing structure with the auxiliary and main stabilizing sleeves working in tandem, guiding and constraining the drill rod during the drilling and deep hole machining stages respectively. This fundamentally ensures a straight drilling trajectory and precise hole positioning, significantly improving drilling accuracy and hole shape quality. The main stabilizing sleeve can move downwards in real time with the drilling depth, and a connector extends into the hole for auxiliary positioning, effectively solving the problems of drill rod wobbling and deflection during deep hole machining, reducing the risk of drill rod vibration and breakage, and extending the service life of the drill rod.
