Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable preservation technology, and more specifically, to a fruit and vegetable preservative spraying device. Background Technology

[0002] Fruits and vegetables are natural, nutritious foods containing a variety of nutrients essential for human life. After harvesting, fruits and vegetables are prone to shrinkage, weight loss, wilting, and spoilage. To reduce or prevent spoilage, preservatives are often sprayed on them to ensure they can be stored for a longer period and remain fresh.

[0003] The application of fruit and vegetable preservatives requires manual spraying on the surface of washed fruits and vegetables, which is time-consuming and labor-intensive in large-scale fruit and vegetable production lines, resulting in low spraying efficiency. In addition, the fruits and vegetables are placed still and have uneven shapes, so it is impossible to ensure that the surface of the fruits and vegetables is sprayed evenly and comprehensively. Therefore, we propose a fruit and vegetable preservative spraying device to solve the above-mentioned problems. Utility Model Content

The outer wall of the rotating shaft 6 is fixedly connected with a spray plate 61 distributed in a circular array. One side of the surface of the spray plate 61 and the bottom of the spray pipe 5 are both connected to an atomizing nozzle 62.

[0029] In this embodiment, preferably, the height of the first conveyor belt 2 in the horizontal direction is greater than the height of the second conveyor belt 4 in the horizontal direction, and a stepped structure is formed between the first conveyor belt 2, the tipping plate 3, and the second conveyor belt 4.

[0030] In this embodiment, preferably, a pump body 7 is fixedly installed on the front of the housing 1. A suction pipe 71 is connected to the input end of the pump body 7. The end of the suction pipe 71 away from the pump body 7 passes through and extends into the interior of the housing 1 to draw in the fruit and vegetable preservative. A diversion pipe 72 is connected to the output end of the pump body 7. The port of the diversion pipe 72 away from the pump body 7 is connected to the spray pipe 5 and the rotating shaft 6 respectively. The pump body 7 pumps out the fruit and vegetable preservative through the suction pipe 71 and then passes it into the rotating shaft 6 and the two spray pipes 5 through the diversion pipe 72 respectively.

[0031] In this embodiment, preferably, both the rotating shaft 6 and the spray plate 61 are hollow components, the spray plate 61 and the rotating shaft 6 are interconnected, both ends of the rotating shaft 6 penetrate and extend to the outside of the housing 1 and can rotate between the rotating shaft 6 and the housing 1 through sealed bearings, one end of the front of the rotating shaft 6 is connected to the diversion pipe 72 through a sealed bearing, and the rotating shaft 6 and the diversion pipe 72 can rotate through the sealed bearings.

The part of the filter plate 9 located inside the box 1 is placed on the support plate 91. When excess preservative drips downwards, it can be filtered by the filter plate 9 and reused.

[0036] The working principle and usage process of this utility model are as follows: Operators place fruits and vegetables in an orderly manner at the right end of the first conveyor belt 2, allowing them to enter the housing 1 through the inlet 11. The pump body 7 pumps the fruit and vegetable preservative through the suction pipe 71, which then flows through the diversion pipe 72 into the rotating shaft 6 and two spray pipes 5 respectively. Finally, the preservative is sprayed out by the atomizing nozzle 62. The first conveyor belt 2 then conveys the fruits and vegetables towards the tipping plate 3. The atomizing nozzle 62 below the spray pipes 5 sprays the preservative onto the surface of the fruits and vegetables, which then fall into the... On the spray plate 61, the atomizing nozzles 62 spray preservative onto the lower surface of the fruits and vegetables. Simultaneously, the stepper motor 8 drives the rotating shaft 6 to rotate via the reducer 81. As the rotating shaft 6 drives the spray plate 61 to rotate, the fruits and vegetables tumble within the turning plate 3. During this tumbling process, the atomizing nozzles 62 on the spray plate 61 continuously spray preservative onto the surface of the fruits and vegetables. The fruits and vegetables are then pushed onto the second conveyor belt 4 and transported to the discharge port 12. During transport on the second conveyor belt 4, they are sprayed with preservative again by the spray pipes 5.

[0037] In summary: Fruits and vegetables enter the box 1 through the inlet 11 of the first conveyor belt 2, are pushed onto the second conveyor belt 4 by the tipping plate 3 and sent out through the outlet 12. The preservative is sprayed onto the surface of the fruits and vegetables by the atomizing nozzle 62. The fruits and vegetables are automatically transported and sprayed with preservative, which saves time and labor and improves efficiency. When the fruits and vegetables pass through the tipping plate 3 during the transport process, they are turned over by the combined action of the tipping plate 3 and the spray plate 61. The atomizing nozzle 62 on the spray plate 61 continuously sprays the preservative onto the surface of the fruits and vegetables, so that the preservative can be sprayed evenly and comprehensively onto the surface of the fruits and vegetables.
