Cold chain box for fresh-keeping transportation of green dates

Abstract

The invention belongs to the technical field of logistics cold chains, and particularly relates to a cold chain box for fresh-keeping transportation of green dates. The cold chain box comprises a heat preservation combined box, a top plate and a bottom plate, wherein a box door is arranged on the side wall of the heat preservation combined box, a bearing plate and an adjusting plate are arranged in the heat preservation combined box, through holes are formed in the bearing plate and the adjusting plate, a plurality of green date suspension springs are fixedly connected to the upper surface of the bearing plate, the upper ends of the green date suspension springs are fixedly connected with magnetic pressing balls, and a protection mechanism is arranged in the heat preservation combined box; and the protection mechanism comprises a plurality of electromagnets embedded in the adjusting plate, the electromagnets are in one-to-one correspondence with the magnetic pressing balls, and the electromagnets and the magnetic pressing balls are opposite in a homopolar mode. According to the cold chain box, the tightness length of the green date suspension springs can be adjusted, the cold chain box is suitable for fixing the green dates with different sizes, the green dates are prevented from falling out in the transportation process, good buffering can be formed in the transportation process of the green dates, the green dates are prevented from being damaged by collision, and the protection effect on the green dates is improved.

Description

technical field [0001] The invention belongs to the technical field of logistics cold chain, and in particular relates to a cold chain box for fresh-keeping and transportation of jujubes. Background technique [0002] Jujube is an excellent tropical and subtropical rare fruit with high nutritional value. During the transshipment process, it needs to be kept fresh and moisturized through cold chain transportation, and it is necessary to avoid collision damage of jujube during transportation. [0003] After searching, the national patent publication number is CN110127176B, which discloses a logistics cold chain box for jujube long-distance transportation, including a heat preservation combination box, a box top combination plate for sealing the top of the heat preservation combination box, a box bottom combination plate and a jujube body , the inner bottom wall of the thermal insulation combination box is fixedly connected with several Qingzao suspension springs, and the inner...
