[0007] Firstly, the sample is placed and fixed on the porcelain boat, then the sliding seat is slowly pushed, and the porcelain boat, the pipe plug and the flange end cover are pushed into the pipe -type furnace hearth as a whole, when the flange end cover reaches the pipe opening, the in -position stop position of the porcelain boat and the pipe plug has been preset, then the flange end cover and the furnace opening are fixed with bolts.

[0008] The sliding seat side surface is hinged with a wrench, the wrench rotating shaft is connected with a cam, and the protruding part of the cam can contact the upper end surface of the pipe rail. The wrench rotating shaft is hinged with the sliding seat shell through a bearing and a torsional spring, and the torsional spring provides a restoring force for the wrench. When the protruding part of the rubber cam is pressed against the surface of the pipe rail, the positioning of the sliding seat is realized.

[0009] The flange plate on the other end of the tubular furnace chamber is movably penetrated by a thermocouple, and the temperature measuring end of the thermocouple can be in contact with the workpiece. The thermocouple is connected to a temperature measuring instrument, and when the tip of the thermocouple touches the workpiece, manual temperature measurement can be performed.

[0010] The end of the chassis is connected to the furnace body through a connecting plate and bolts. The chassis and the entire feeding mechanical device can be removed and installed on other tubular furnaces through the connecting plate, and by replacing the flange, pipe plug and other components, universal use can be achieved.

[0011] The L-shaped plate is provided with a vertical long hole, and the bolts are anchored and fixed to the flange plate through the long hole. The bolts can be anchored at a suitable position on the long hole, thereby adjusting the height of the entire feeding and improving the universality of the feeding mechanical device.

[0012] Advantages of the utility model

[0013] 1. The utility model changes the current situation that the existing tubular furnace needs manual feeding and manual placement of the pipe plug, and directly feeds by using the feeding mechanical device, which is not only accurate in feeding position, but also fast and convenient.

[0014] 2. The feeding mechanical device of the utility model can be installed and used on tubular furnaces of multiple sizes and various specifications, and can be universally adapted by adaptive adjustment and replacement of components. BRIEF DESCRIPTION OF DRAWINGS
