The invention provides a combined sample feeding device. The device comprises a bottom cover plate; the upper end of the bottom cover plate is fixedly connected with T-shaped plates, plug heads and along outer frame through screws; the upper end of the long outer frame is fixedly connected with a large blocking plate through screws; outer separation plates and inner separation plates are fixed tothe front end surface of the large blocking plate; the outer separation plates and the inner separation plates are disposed on the left side and right side of pull plates; the outer separation platesand the inner separation plates are fixed on the upper end surfaces of the plug heads; the upper ends of the outer separation plates and inner separation plates are fixedly connected with panels through screws; the front ends of the panels are fixedly connected with aluminum frames through screws; the front ends of the aluminum frames are provided with pull plate sealing frames; and the rear endsof the pull plate sealing frames are fixedly connected with pull plates through screws. According to the combined sample feeding device of the invention, splicing assembling is adopted, and therefore, the device can be spliced according to different types of equipment; the device can be spliced according to the number of channels required by a user in a production process; and the device can be spliced and upgraded at a user site.

The invention relates to the technical field of traffic guardrails, and discloses a high-safety grid type traffic guardrail which comprises a plurality of guardrail units. Each guardrail unit comprises two bases, two stand columns, two cross beams and a plurality of railings, the lower ends of the two stand columns are detachably connected with the upper ends of the two bases correspondingly, the side walls of the two stand columns are each fixedly connected with a set of connecting blocks, the two connecting blocks in each set are located at the upper ends and the lower ends of the side walls of the stand columns correspondingly, the left ends and the right ends of the two cross beams are each fixedly connected with a first connecting plate, the two sets of first connecting plates are fixedly connected with the two sets of connecting blocks through first fixing bolts correspondingly, and the two cross beams are arranged in parallel. The multiple railings are located between the two cross beams and are vertically arranged, and the upper ends and the lower ends of the railings are fixedly connected with second connecting plates. The guardrail is convenient to splice and assemble, convenient to disassemble and carry, and capable of reflecting light to warn vehicles running at night so that the travel safety of people is improved.

The invention relates to a circular miniature slide-resistant pile die with an adjustable height and an adjustable sectional area. Plug boards are utilized as parts for forming the die in a split joint mode, and the plug boards are divided into major plug boards, minor plug boards and bottom plug boards according the positions where the plug boards are located on a cylinder structure when the plug boards are assembled, the major plug boards are located on the upper layer positions on the cylinder structure, the minor plug boards are located on the middle layer positions on the cylinder structure, and the bottom plug boards are located on the lower layer positions on the cylinder structure. The lengths and widths of all the plug boards in the same die are the same, the heights of the major plug boards are the same, the heights of the minor plug boards are the same, and the heights of the bottom plug boards are the same. One edge of each plug board in the vertical direction is machined with a vertical plug bar, and a vertical plug groove is formed in the other edge of each plug board. A transverse plug groove is formed in the transverse lower side edge of each major plug board, and a transverse plug groove is formed in the transverse lower side edge of each minor plug board. A transverse plug bar is formed in the upper side edge of each major plug board, and a transverse plug bar is formed in the upper side edge of each minor plug board. Each transverse plug bar on each upper side edge is matched with each transverse groove in each lower side edge. When the plug boards are assembled, the major plug boards, the minor plug boards and the bottom plug boards are connected in an up-and-down left-and-right split joint mode to form the die which is in a nearly cylindrical shape. According to the circular miniature slide-resistant pile die with the adjustable height and the adjustable sectional area, the sectional area can be adjusted through changing of a left-and-right split joint number of the plug boards, the height can be adjusted through changing of an up-and-down connecting layer number of the plug boards, the circular slide-resistant pile die with the adjustable height and the adjustable sectional area can be spliced through only one set of plug boards, and the circular miniature slide-resistant pile die with the adjustable height and the adjustable sectional area is simple in structure, easy to splice and low in use cost.
