Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum precooling equipment, specifically relating to a portable precooling device for harvested fruits. Background Technology

[0002] Greenhouse cultivation technology involves constructing facilities (greenhouses) covered with light-transmitting materials and precisely controlling environmental factors such as temperature, light, humidity, gases (such as CO2), and water and fertilizer within the greenhouse to create optimal conditions for crop growth. Its core lies in environmental control, combining key technologies such as drip irrigation, integrated water and fertilizer management, intelligent monitoring, and soil management to achieve off-season crop cultivation, resist natural disasters, and improve yield and quality. It is an important model for efficient and intensive production in modern agriculture.

[0003] However, when harvesting fruit in greenhouses, the high temperature inside and the large temperature difference between the inside and outside of the greenhouse can easily affect the taste and color of the fruit, making it difficult to preserve. Current vacuum precooling equipment is bulky and inconvenient to move, and manually handling the harvested fruit is time-consuming and labor-intensive. Therefore, we have proposed a portable fruit precooling device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the taste and color of fruits are easily affected when harvesting fruits in greenhouses due to the high temperature inside the greenhouse and the large temperature difference between the inside and outside.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A portable fruit pre-cooling device includes a housing with multiple internal cavities, multiple containers movably installed within the cavities for storing fruit, a cooling assembly, and a vacuum assembly for extracting air from the containers. Each container has an opening at its upper end with a groove inside the opening. A cover plate is movably installed within the groove, and an elastic sealing strip is provided on the side of the cover plate that contacts the groove. A pull strip is fixedly installed at the top center of the cover plate. A fixing plate is fixedly installed on the side of the container away from the housing, and the fixing plate has a groove. A sealing strip is provided between the fixing plate and the housing. The cooling assembly includes a body containing a compressor and a condenser, an evaporator embedded within the housing, and a return pipe and capillary tube disposed between the body and the evaporator. The body is fixedly installed on one side of the housing, and a power supply system for providing power to the cooling assembly and the vacuum assembly is fixedly installed on one side of the housing. The power supply system consists of a battery and a controller.

[0007] Further specifying, the vacuum assembly includes a vacuum pump, a gas supply pipe fixedly installed at the inlet of the vacuum pump, multiple branch pipes fixedly installed on the gas supply pipe, and multiple one-way valves respectively fixedly installed at the ends of the branch pipes. A support platform is fixedly installed on the housing, the vacuum pump is fixedly installed on the support platform, and the multiple one-way valves are fixedly inserted into the back of the housing and are respectively connected to multiple receiving cavities. Through holes are opened on the back of the multiple holding boxes corresponding to the one-way valves, and isolation mesh plates are fixedly installed at the through holes. With this structural design, when the vacuum pump is working, the one-way valves can draw air out of the holding boxes, creating a vacuum state.

[0008] Furthermore, a slot is provided on one side of the container, and multiple electric push rods are fixedly installed on the box body. A wedge is fixedly installed at the movable end of each electric push rod, and the wedge penetrates the box body and fits into the slot. This structural design allows the electric push rods, in conjunction with the wedges, to engage with the box body, locking the container within its receiving cavity.

[0009] Further specifying, a movable plate is fixedly installed at the lower end of the housing, and a push handle is fixedly installed on the movable plate. Two sets of rollers are provided at the lower end of the movable plate, and a drive motor is mounted on the movable plate. A first friction wheel is fixedly installed on the output shaft of the drive motor, and a second friction wheel is fixedly installed on the shaft of one set of rollers. A transmission belt is fitted onto the first and second friction wheels. A control button for controlling the operation of the drive motor is provided on the push handle, and a bracket is fixedly installed on the push handle. A control panel is fixedly installed on the bracket, and the control panel is electrically connected to the drive motor, electric push rod, power supply system, vacuum assembly, and cooling assembly.

The second cover 714 is also provided with an air outlet corresponding to the air outlet of the vacuum pump 41.

[0040] The method of using this utility model is as follows:

[0041] When in use, the precooling equipment is pushed into the greenhouse by pushing the handle 71 and the movable plate 7. The cooling component 3 works, and the body 31, together with the return pipe and capillary tube, allows the evaporator embedded in the box 1 to absorb heat, thereby reducing the temperature inside the containment cavity. The pickers can put the picked fruits into the holding box 2. After the fruits are placed in the holding box 2, the cover plate 21 is placed on the groove on the holding box 2, and then pushed into the containment cavity of the box 1. When the back of the holding box 2 abuts against the end of the one-way valve 44, the wedge at the end of the electric push rod 6 is engaged in the slot 27, which can lock the holding box 2 to prevent the holding box 2 from falling out of the containment cavity of the box 1.

[0042] When the vacuum pump 41 is working, it can open the one-way valve 44 through the gas supply pipe 42 and the branch pipe 43, and draw the air out of the container 2 until the container 2 is in a vacuum state. At this time, the fruit in the container 2 is in a vacuum low temperature environment, which is conducive to the preservation of the fruit and can keep the taste and color of the fruit for a longer time.

[0043] The above provides a detailed description of a portable fruit pre-cooling device for harvesting provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
