Description

Technical Field

[0001] The utility model relates to the field of vegetable drainers, in particular to a vibration drainer for processing agricultural product lettuce. Background Art

[0002] Agricultural product lettuce processing involves a series of links from planting and harvesting to processing, packaging and transportation. In this process, the quality and safety of lettuce are crucial because they are directly related to the health and satisfaction of the final consumer. The main purpose of lettuce processing is to maintain the freshness of lettuce and extend its shelf life without compromising the original nutrition and flavor, so as to facilitate long-distance transportation and sales.

[0003] The lettuce processing steps include washing, rooting, cutting, draining, bundling, bagging, framing, etc. After the lettuce is picked, it needs to be washed, rooted and cut, and then the moisture on the surface of the cut lettuce is removed, and finally it is bundled or bagged and stored and transported at an appropriate temperature.

[0004] A lettuce drainer is used in the draining process. Its working principle is to achieve the purpose of draining by rotating or vibrating so that the water attached to the surface of the vegetables is thrown out by centrifugal force. Because lettuce is a leafy vegetable, too large an amplitude of rotation or vibration can easily damage the lettuce leaves and affect the appearance. Most of the existing vibrating drainers for lettuce processing are equipped with inclined vibrating drain plates, and the inclination angle of the drain plate cannot be adjusted according to each stage of draining. If the lettuce is to be transported and rolled on the drain plate, a steeper inclination angle is required. However, if the inclination angle is always steep, the produce will stay on the drain plate for too short a time, resulting in incomplete drainage of the water. If the inclination angle is not enough, the produce will accumulate on the drain plate, affecting subsequent transportation. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects: the inclination angle of the vibrating screen in different stages of production drainage can be controlled by the control panel. When the lettuce just falls onto the vibrating screen from the loading and conveying platform, the vibrating screen is driven by the electric telescopic rod to achieve a larger inclination angle, which is convenient for the conveying of the lettuce and avoids accumulation. When the object sensor on the baffle senses that the lettuce has reached the lower end of the inclination, the vibrating screen is flattened under the drive of the electric telescopic rod to vibrate and drain, and the blowing structure is used to speed up the removal of moisture on the surface of the lettuce. After the drainage is completed, the vibrating screen is tilted again and the baffle is moved up, so that the lettuce falls onto the unloading and conveying platform after being sterilized by the ultraviolet sterilization lamp and enters the next packaging procedure, so that the entire drainage process is automatically controlled, and the draining time of the lettuce is taken into account to avoid leaving the vibrating screen too quickly, and the accumulation of lettuce is also taken into account to affect the transportation.

Both the loading conveyor platform 3 and the unloading conveyor platform 4 can use the conveyor platform structure capable of intermittent pause conveying in the prior art.

[0026] Both the feeding conveyor platform 3 and the unloading conveyor platform 4 include an intermittent conveyor belt 17 and a drive motor 18. The drive motor 18 can drive the intermittent conveyor belt 17 to realize intermittent conveying. The lettuce is conveyed from the intermittent conveyor belt 17 of the feeding conveyor platform 3 to the inside of the drain box 1. After being drained, the leftovers fall into the unloading conveyor platform 4. The intermittent conveyor belt 17 conveys the drained lettuce to the packaging machine for packaging. Under the driving action of the drive motor 18, the intermittent conveyor belt 17 cooperates with the control panel 5 to perform intermittent pauses and convey the lettuce.

[0027] A control panel 5, a blowing structure 6 and an ultraviolet sterilization lamp 7 are respectively provided on the top of the drain box 1. The blowing structure 6 and the ultraviolet sterilization lamp 7 are both fixedly arranged on the top wall of the drain box 1. The blowing structure 6 is preferably an electric hair dryer, which can cooperate with the vibrating screen 8 to quickly dry the moisture on the surface of the lettuce below. The ultraviolet sterilization lamp 7 is arranged on a side close to the unloading conveying platform 4 to sterilize and disinfect the lettuce.

[0028] A vibrating screen 8 is provided inside the drain box 1. The vibrating screen 8 includes a bottom plate 21 and a side plate 22. A vibration motor 25 and a buffer pad 23 are fixedly provided on the bottom wall and the top wall of the bottom plate 21, respectively. The buffer pad 23 is preferably made of a polyurethane rubber pad to reduce damage during the transportation of lettuce. A number of drainage holes 24 are provided through the buffer pad 23 and the bottom plate 21. The side plate 22 is fixedly provided on the three side walls of the bottom plate 21 away from the unloading conveying platform 4 to prevent the lettuce from being thrown out of the vibrating screen 8 during vibration. During the vibration drainage stage, the vibration motor 25 is started to drive the bottom plate 21 and the buffer pad 23 to vibrate.

A first slide groove 19 and a support block 20 are provided under the through slot 2 near the side of the loading and conveying platform 3. The electric telescopic rod 11 is fixedly provided on the top wall of the support block 20, and the connecting block 10 can slide up and down in the first slide groove 19.

[0030] Start the electric telescopic rod 11 to drive the connecting block 10 to move upward, thereby causing one end of the vibrating screen 8 to move upward until the connecting block 10 moves to the uppermost end of the first slide groove 19. At this time, the inclination of the vibrating screen 8 is the largest, and the inclined upper end is also closest to the feeding conveyor platform 3. After the lettuce falls from the feeding conveyor platform 3 onto the buffer pad 23 below, the damage is reduced to a minimum, and the production is delayed and the lettuce is rolled downward along the inclined buffer pad 23.
