Description

Technical Field

[0001] This utility model relates to the technical field of freeze dryer feeding equipment, and more specifically, to a structure for a manual mechanical feeding trolley for a freeze dryer. Background Technology

[0002] A freeze dryer (vacuum freeze dryer) is a drying device that removes moisture by first freezing materials containing a large amount of water into a solid state, and then sublimating the ice into a gaseous state under vacuum. This drying method effectively preserves the original characteristics of the material, such as its shape, nutritional components, and biological activity. Material transport is typically accomplished using a manually operated mechanical trolley structure. The main frame, lifting frame, material carrying platform, and material limiting cover work together to arrange the material, making it easy for operators to push the entire unit to the freeze dryer.

[0003] The existing material handling platform is located above the main frame and is connected to the main frame via a lifting device to achieve height adjustment. This lifting device typically uses a screw and a scissor beam for adjustment, with the screw's threaded locking mechanism determining the platform's height. This results in the weight of the material placed on the platform being borne entirely by the screw, leading to thread damage due to pressure and reduced platform stability during movement. Furthermore, the platform automatically lowers when materials are placed into the freeze dryer, affecting material transport safety. Therefore, a structure that can provide auxiliary support for the screw to improve overall compressive strength is needed. Based on this, we propose a structure for a manual mechanical feeding trolley in a freeze dryer. Utility Model Content

[0009] Preferably, a plurality of movable grooves are formed in the plate wall of the mobile base, and an adjusting piece is fixedly arranged at the bottom of the mobile base and abuts against the bottom of the horizontal plate through the movable grooves.

[0010] Preferably, the adjusting piece comprises an extrusion block with an inclined top surface, an L-shaped plate is fixedly arranged at the bottom of the extrusion block, and an electric push rod is fixedly arranged on one side of the L-shaped plate and mounted on the bottom of the mobile base.
