The degradable master batch extrusion molding device comprises an extrusion molding machine, a feeding hopper is installed at the top end of the extrusion molding machine, a feeding cover is arranged outside the top end of the feeding hopper in a sleeved mode, crushing rollers are arranged on the two sides of the bottom end of the interior of the feeding hopper, an outer ring is arranged outside the feeding hopper in a sleeved mode, and the outer ring is provided with a feeding hole. And temporary storage cavities are uniformly formed in the outer ring. Through the action of the outer ring, when the master batch upwards rushes out, the master batch can be temporarily stored in the temporary storage cavity, possible continuous upwelling of the master batch in the crushing process is reduced due to the fact that the inner diameter of the temporary storage cavity is different from the inner diameter of the feeding hopper, and the master batch can be conveniently and rapidly crushed through cooperation of the rotating block, the supporting ring and the like. Therefore, the top end of the feeding hopper can be shielded to a certain degree, the size of an opening of the feeding hopper is reduced, and upward splashing of the master batch in the crushing process is reduced.

The application discloses a mortise cover plate type nested assembly type beam column connecting joint, which comprises a column assembly, a beam assembly and a connecting piece. The column assembly comprises an upper steel column, a lower steel column and a box-shaped bracket with an embedded bolt pipeline; the beam assembly comprises a horizontal I-shaped steel beam and a box-shaped accessory with an embedded bolt pipeline; and the connecting piece comprises a mortise cover plate and high-strength bolts, all the accessories are welded in a factory. When being installed, the box-shaped accessory with the embedded bolt pipeline is placed into the box-shaped bracket with the embedded bolt pipeline along the horizontal direction, and the beam column assembly is connected by the mortise cover plate, so that the integrity of the joint area is better, and finally the fastening between the components is completed by the high-strength bolts. The assembly type beam column joint provided by the application is connected by full bolts at a construction site, is convenient to operate, shortens the construction time, is green and environment-friendly, and has good mechanical properties; the upper and lower flange surfaces of the I-shaped steel beam are kept flat, and the subsequent floor installation is facilitated; and the joint body is in a nested structure, so that the rigidity and the strength of the joint are effectively improved.

The invention belongs to the field of electrical equipment, and relates to a control cabinet top. The cabinet top of the control cabinet comprises a top plate, a rotating structure, a spring, a rotating pipe, a cover body, a wind resistance structure, a movable scraping structure and a pull rope. An opening is formed in the top plate; the rotating structure is rotatably mounted below the opening of the top plate, the rotating structure is connected with a spring, and the upper end of the spring is connected with a rotating pipe; a cover body is fixedly mounted at the upper end of the rotating pipe; a through hole with the same inner diameter as the rotating pipe is formed in the cover body; a wind resistance structure is slidably installed on the cover body, a movable scraping structure capable of moving up and down is arranged below the wind resistance structure, and the lower surface of the movable scraping structure makes contact with the top plate. The wind resistance structure is connected with a pull rope, and the pull rope penetrates through the rotating pipe and is connected with the rotating structure. According to the control cabinet top, a top air outlet heat dissipation mode of an indoor control cabinet is reserved, heat at the top of the cabinet body can be dissipated, external rain and snow are prevented from entering the cabinet body, and heat dissipation can still be kept in rainy, snowy and windy weather.
