DETAILED DESCRIPTION

[0018] Please refer to Figures 1-5 The utility model discloses a grain container with thermal insulation layer for loading and unloading grain, which comprises a top plate, a bottom frame, side plates, a door plate and a front wall, and the door plate and the front wall are respectively located at two ends of the container in the length direction.

[0019] The top plate comprises an inner top plate and an outer top plate, and the inner top plate and the outer top plate are filled with thermal insulation foaming material to form a thermal insulation foaming layer 101 of the top plate; a plurality of inner top plate reinforcing ribs and a plurality of outer top plate reinforcing ribs 107 are welded to opposite sides of the inner top plate and the outer top plate respectively, and the inner top plate reinforcing ribs and the outer top plate reinforcing ribs 107 are distributed in a staggered manner.

[0020] The side plate comprises an inner side plate and an outer side plate, and the inner side plate and the outer side plate are filled with thermal insulation foaming material to form a thermal insulation foaming layer 103 of the side plate; a plurality of inner side plate reinforcing ribs and a plurality of outer side plate reinforcing ribs 106 are welded to opposite sides of the inner side plate and the outer side plate respectively, and the inner side plate reinforcing ribs and the outer side plate reinforcing ribs 106 are distributed in a staggered manner.

[0021] The front wall comprises an inner front wall and an outer front wall, and the inner front wall and the outer front wall are filled with thermal insulation foaming material to form a thermal insulation foaming layer 105 of the front wall; a plurality of front wall reinforcing ribs 108 distributed in a staggered manner are welded to opposite sides of the inner front wall and the outer front wall.

[0022] The inside of the chassis and the door plate are also filled with thermal insulation foaming material to form a thermal insulation foaming layer 102 of the chassis and a thermal insulation foaming layer 104 of the door plate respectively. Considering the particularity of the grain transport box, the thickness design range of the thermal insulation foaming layer 101 of the top plate, the thermal insulation foaming layer 103 of the side plate, the thermal insulation foaming layer 105 of the front wall, the thermal insulation foaming layer 102 of the chassis and the thermal insulation foaming layer 104 of the door plate can be 100mm-130mm.
