In the above-mentioned device for prolonging the preservation of fruits and vegetables, the ultraviolet lamp is arranged in the protective cover, and the conveyor belt passes through the protective cover to prevent ultraviolet rays from scattering to the outside.

In the above-mentioned device for prolonging the preservation of fruits and vegetables, a guide roller is provided under the conveyor belt, which plays a guiding and supporting role for the conveyor belt.

In the above-mentioned device for prolonging the preservation of fruits and vegetables, the inner wall of the protective cover has an ultraviolet light reflection layer, so as to improve the utilization rate of light.

In the above-mentioned device for prolonging the preservation of fruits and vegetables, the feeding port of the protective cover is provided with a distributing claw, a gear lever is arranged on the distributing claw, the gear lever is arranged in the up and down direction, and the upper end of the gear lever is fixedly connected to the The upper edge of the feeding port of the protective cover leaves a gap between the lower end of the stop rod and the surface of the conveyor belt. The blocking rod makes the feeding port of the protective cover form a plurality of small parallel feeding gaps, so that the fruits and vegetables on the conveyor belt are evenly dispersed. into the protective cover. The protective cover discharge port is provided with a baffle, and the distance of the baffle relative to the surface of the conveyor belt is controlled by a lifting mechanism. When the baffle moves down close to the surface of the conveyor belt, it blocks the movement of fruits and vegetables. When the accumulation reaches a certain amount, the baffle moves up so that the accumulated fruits and vegetables are removed under the drive of the conveyor belt, and then the baffle moves down to block the fruits and vegetables behind.

Compared with the prior art, the device for prolonging the preservation of fruits and vegetables has the following advantages:

The belt body of the conveyor belt adopted by the utility model is a material that can transmit ultraviolet light, such as a quartz glass plate, which can be irradiated with ultraviolet light on both sides of the quartz glass plate, so as to realize the omnidirectional irradiation of fruits and vegetables, and solve the problem that the traditional conveyor belt cannot be realized. . The surface hardness of fruits and vegetables can be maintained, and the color change and ripening can be delayed through the irradiation treatment of ultraviolet light. The structure of the equipment is simple, and the conveyor belt conveys the processing quickly.
