一种移动式田头太阳能预冷箱 技术领域
本发明涉及农业预冷箱技术领域，特别涉及一种移动式田头太阳能预冷箱。
背景技术
在农业果蔬种植过程中，农产品成熟后需要采摘，采摘过后需要通过冷藏车运往仓库或者直接发送销售市场，由于冷冻车自重过大，无法下地，一旦下地会造成土地板结，影响土地肥沃程度，因此采摘过程中往往需要小型运输车，将采摘后的农产品运送至冷藏车处，且农产品在从采摘下到进入冷藏车过程中会产生一定损失，为降低从采摘到运输的最初这一过程中农产品的损失，需要用到预冷箱。
专利号CN110006202A公开的一种产地预冷箱，包括箱体，箱体前侧安装有箱门，箱门表面活动安装有取物门，箱体内部设置有预冷柜，预冷柜上表面中部固定安装有上半导体制冷模组，预冷柜下表面中部固定安装有下半导体制冷模组，箱体内部在预冷柜外围设置有吸热循环管组，箱体上表面开设有安装口，安装口内固定安装有储水箱，吸热循环管组与储水箱连接，该发明虽然能起到一定预冷效果，但是设备结构复杂，且无法在田间地头移动，由于田间地头路面不平整，极易造成农产品磕碰，依旧使得农产品在最初始这一过程中造成损失，因此有必要提出一种新的解决方案。
现有的预冷箱只有预冷的效果，但是在田间地头中使用时依旧会 造成农产品损失，且预冷效果差以及节能效果差，为此，我们提出一种移动式田头太阳能预冷箱。
