Description

Technical Field

[0001] The utility model belongs to the technical field of seedling packaging, and in particular relates to a seedling packaging constant temperature transportation device. Background Art

[0002] Seedlings refer to seeds that have germinated after being sown. Generally, they grow to two pairs of true leaves and become full disks, which are suitable for transplanting to other environments to grow as young plants.

[0003] Some seedlings are stored at low temperatures in winter and transplanted in the spring of the following year. Seedlings need to be placed in packaging and transportation boxes before transplanting. Seedlings need to be transported before packaging. Currently, flatbed trucks are mostly used for transportation. The transportation process is not only easy to cause damage to the seedlings, but also the transportation efficiency is also very low. In addition, since the ambient temperature during transportation is not at a suitable temperature for seedlings, the survival rate of the seedlings is reduced. Utility Model Content

[0004] The utility model aims to provide a seedling packaging constant temperature transportation device to solve the problem that the existing seedling survival rate is low due to unsuitable transportation environment temperature before seedling packaging.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A seedling packaging constant temperature transportation device comprises a conveyor line, one end of which is provided with a feeder, a heating chamber, a moisturizing chamber and a constant temperature chamber are sequentially provided on the conveyor line in the conveying direction of the conveyor line, the heating chamber is provided with an electric heating mechanism, the moisturizing chamber is provided with an ultrasonic humidification mechanism, the constant temperature chamber is provided with an air collecting pipe, the air collecting pipe is connected to a plurality of gas distributors, the air collecting pipe is connected to an air collecting box, the air collecting box is connected to an air inlet pipe, the air inlet pipe is connected to a heating air source, a flow regulating valve is provided on the air inlet pipe, a temperature monitor is provided in the constant temperature chamber, the temperature monitor is electrically connected to a PLC controller by a signal, and the PLC controller is electrically connected to the flow regulating valve by a signal.

[0008] Furthermore, the outer wall of the air collecting box is provided with a heat-insulating layer.

[0009] Furthermore, the gas collecting pipe is connected to the gas collecting box through an air delivery pipe, and a booster pump is provided on the air delivery pipe.

[0010] Furthermore, a plurality of ultrasonic humidification mechanisms are evenly distributed on both sides of the conveying line in the moisturizing cabin.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. The utility model comprises a conveyor line, one end of which is provided with a feeder, a heating chamber, a moisturizing chamber and a constant temperature chamber are sequentially provided on the conveyor line in the conveying direction of the conveyor line, the heating chamber is provided with an electric heating mechanism, the moisturizing chamber is provided with an ultrasonic humidifying mechanism, the constant temperature chamber is provided with a gas collecting pipe, the gas collecting pipe is connected with a plurality of gas distributors, the gas collecting pipe is connected with a gas collecting box, the gas collecting box is connected with an air inlet pipe, the air inlet pipe is connected with a heating gas source, a flow regulating valve is provided on the air inlet pipe, a temperature monitor is provided in the constant temperature chamber, the temperature monitor is electrically connected with a PLC controller by a signal, and the PLC controller is electrically connected with the flow regulating valve by a signal.

[0013] Through this arrangement, the loader loads the seedlings to be packaged onto the conveyor line, and the seedlings are conveyed along the conveyor line to the heating cabin. The electric heating mechanism in the heating cabin releases heat to heat the seedlings to a temperature close to a preset suitable temperature value. The seedlings pass through the heating cabin and enter the moisturizing cabin. The ultrasonic humidification mechanism in the moisturizing cabin can moisturize the warmed seedlings to ensure that the seedlings are within a preset suitable humidity range. After passing through the moisturizing cabin, the seedlings enter the constant temperature cabin, and the air inlet pipe introduces the heated gas from the heating gas source into the air collecting box, and then into the air collecting pipe, and finally dispersed from the gas distributor into the constant temperature cabin. During transportation, the seedlings in the constant temperature cabin are slowly and evenly heated to the preset suitable temperature value and kept consistent with the temperature in the constant temperature cabin, so as to achieve constant temperature transportation at a suitable temperature. The temperature monitoring meter is used to detect whether the temperature in the constant temperature cabin is at the preset suitable temperature value. If the temperature in the constant temperature cabin is lower than the preset suitable temperature value, the PLC controller immediately controls the flow regulating valve to increase the flow of the heating gas to ensure that the temperature in the constant temperature cabin is at the preset suitable temperature value, which effectively solves the problem that the existing transportation environment temperature before seedling packaging is not suitable, resulting in a low survival rate of seedlings.
