The utility model discloses a kind of big span crossbeam guide rail micro-deformation adjustment structure and adjustment system, above-mentioned adjustment structure includes unloading plate, draw plate, screw rod and nut, draw plate is installed in the middle region of crossbeam side, unloading plate is located in the side of draw plate, unloading plate is installed on crossbeam side, one end of screw rod is installed on unloading plate, the other end of screw rod extends through draw plate and is spirally connected on nut after.The adjustment system provided by the utility model can realize the fine adjustment of the bending degree and the torsion overturning deformation of the crossbeam guide rail, to improve the linearity of the crossbeam guide rail. Compared with the prior art, the adjustment system realizes the precision adjustment of the guide rail under the assembly state of the crossbeam, avoids the reprocessing of the crossbeam guide rail, improves the efficiency while reducing the cost. In addition, the adjustment system also solves the problem of the existing technology difficult to improve the forward deformation of the crossbeam guide rail, can obviously improve the linearity of the crossbeam guide rail in two directions.

The side hanging type carrot harvester comprises a hanging frame, a mounting plate is fixedly mounted on the side face of the upper end of the hanging frame, supporting wheels are rotationally mounted on the side faces of the two ends of the lower side of the hanging frame, and a lug plate at the bottom of the upper end of the hanging frame is rotationally connected with lug plates at the tops of one ends of two conveying mechanisms; a lug plate at the bottom of the middle of the hanging frame is rotationally connected with one end of a hydraulic cylinder, and the other end of the hydraulic cylinder is rotationally connected with lug plates at the tops of the other ends of the two conveying mechanisms. According to the side hanging type carrot harvester, resistance to carrot seedling leaves during seedling arranging can be effectively reduced, and therefore the seedling leaves are prevented from being pulled apart in the harvesting process; the seedling cutting device has the advantages that the seedling cutting position can be adjusted according to the height of the carrots, seedling leaves on the carrots can be accurately cut off, the seedling leaves can be thoroughly cut off, follow-up retreatment of the seedling leaves is avoided, cost is reduced, and the quality of the harvested carrots is improved.

The utility model belongs to the field of liquid nitrogen container discloses a low temperature storage container, including top layer, interlayer, bottom layer and stand, top layer, interlayer, bottom layer and stand are sheet metal spare, top layer, interlayer and bottom layer are connected with stand through the clamping structure respectively. The utility model's clamping structure sets up the plug -in piece and the limiting portion in concentration, can make the limiting portion when the connecting plate part one and the connecting plate part two carry out the clamping can be synchronous and be in place, and the limiting portion cooperation hole portion's stop retreats part can realize the stop retreat effect, and the assembly is convenient, also avoided the stop retreat structure and needed to set up on the stand and led to the situation of carrying out the secondary processing to the stand, reduced the processing procedure, improved the degree of simplification of container surface structure.

The application discloses a forming equipment with a mold core self-checking function for producing a harmonica tube, which comprises a mold, a conveyor, a rotating shaft with clamping pieces, a turnover chuck and a detection module. The application can analyze the cross section of the profile after cutting to determine whether the mold core inside the mold has a quality reduction. The detection process is timely and accurate. If the mold core quality is reduced, the aluminum rod can be extracted in time to avoid extruding the remaining aluminum rod into an unqualified mold, thereby reducing the product rework caused by mold quality, reducing production costs, and avoiding the situation that the aluminum rod is stranded in the extrusion chamber for cooling. The aluminum rod does not need to be heated again during subsequent secondary use, avoiding repeated processing, improving work efficiency, and also flattening the profile for the first time, which can ensure that the profile deformation force direction and the tension direction coincide to improve the profile levelness.
