Description

Double-track four-sided oscillating spray washing machine for turnover boxes / baskets Technical Field

[0001] This utility model relates to a cleaning system for storage and turnover equipment of fruits and vegetables, and more particularly to a double-track, four-sided swing spray washing machine for turnover boxes / baskets on such equipment. Background Technology

[0002] In the warehousing and turnover of goods such as fruits and vegetables, it is generally necessary to consider the use of turnover boxes for storage or turnover management. Each turnover box needs to be cleaned before being used again. This is because dirt can easily adhere to the inner and outer walls of the turnover boxes during use, especially the dirt on the inner walls, which directly affects the hygiene and health of the stored products. Therefore, regular cleaning with cleaning equipment or machines is usually required. In existing technology, cleaning equipment or machines are typically used to clean turnover boxes to improve cleaning efficiency. The following defects exist: 1. Existing turnover box cleaning machines use tap water spraying for the first stage, which results in poor cleaning effectiveness; 2. Existing turnover box cleaning machines all use fan-shaped nozzles, and the spray pipes for installing these nozzles are fixed. This means the angle and area that the fan-shaped nozzles can spray on the turnover boxes is fixed, resulting in some areas of the turnover boxes or frames not being sprayed, and the nozzles having no pressure, thus leading to poor cleaning results; 3. The pressure strip structure of existing turnover box washing machines is either fixed or requires manual adjustment. This is inconvenient to operate, and the fixed type can only clean one type of turnover box frame, thus failing to achieve the goal of cleaning multiple turnover box frame types of different heights and sizes with one machine.

[0003] Patent No. ZL 202221862666.4, published on November 29, 2022, discloses a spray cleaning line for plastic turnover boxes, comprising: a frame, a chain conveyor belt, and a cleaning hood; the chain conveyor belt is installed in the middle of the frame, and the cleaning hood is fixed to the upper part of the front end of the frame by bolts; the spray pipe is fixed to the inner wall of the cleaning hood by welding, and multiple high-pressure nozzles are screwed onto the outer wall of the spray pipe; the upper drying hood is fixed to the upper part of the rear end of the frame by bolts, and baffles are hinged to the front and rear ends of the upper drying hood; the air hoods are respectively fixed to the upper part of the upper drying hood and the lower part of the lower drying hood by welding. Through structural improvements, this line offers advantages such as good cleaning and disinfection effects for plastic turnover boxes, drying function, and easy and quick use, greatly improving its practical performance and value, thus effectively solving the problems and shortcomings of existing devices. The proposed solution uses a spray pipe that is welded to the inner wall of the cleaning hood, but it still suffers from the defects mentioned above by the applicant. Summary of the Invention

[0004] This utility model provides a double-track, four-sided oscillating spray washing machine for turnover boxes or baskets of fruits and vegetables, which solves the problems of poor cleaning effect and the risk of blind spots in the cleaning of existing turnover boxes or baskets. It has a better cleaning effect, can better clean blind spots more thoroughly, and has high cleaning efficiency and high cleaning quality.

[0005] The specific technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a double-track four-sided swing spray washing machine for turnover boxes / baskets, including a spray washing machine frame and its spray cleaning area, characterized in that: the spray cleaning area adopts a four-sided swing high-pressure spray cleaning area with no dead angles. In the four-sided swing high-pressure spray cleaning area with no dead angles, a set of swing spray frame cleaning mechanism is provided at each of the four directions of turnover boxes / baskets in the four directions of up, down, left, and right. Each set of swing spray frame mechanism has a swing spray frame and a swing rotation drive structure. The swing spray frame is provided with multiple spray pipes, and multiple spray heads are distributed on each spray pipe. The swing rotation drive structure drives the corresponding swing spray frame to swing in the cleaning area, causing the multiple spray heads distributed on the multiple spray pipes to follow the swing spray cleaning. The four sets of swing spray frame cleaning mechanisms form a four-sided swing high-pressure spray cleaning mechanism for turnover boxes / baskets with no dead angles. The system features a set of swing-type spray racks at each of the four cardinal directions (top, bottom, left, and right) of the turnover boxes / baskets, creating a four-sided, high-pressure spray cleaning zone with no blind spots. Each spray pipe is equipped with multiple spray heads, ensuring thorough cleaning of all four sides of the turnover boxes / baskets. Simultaneously, as the boxes / baskets move in and out of the spray cleaning zone, the front and back, inner and outer surfaces are also subjected to the same high-pressure spray cleaning. This achieves a 360-degree, thorough cleaning of the turnover boxes / baskets, eliminating any blind spots. The cleaning effect is excellent, effectively cleaning hard-to-reach areas, resulting in high cleaning efficiency and quality.

[0006] Preferably, the spray cleaning area includes two or more high-pressure oscillating spray cleaning zones, each equipped with a four-sided oscillating spray frame mechanism. In the first high-pressure oscillating spray cleaning zone at the inlet of the turnover box / basket, warm water with alkali or warm water with edible alkali is used as the input cleaning solution. In the second high-pressure oscillating spray cleaning zone or the high-temperature oscillating spray cleaning zone following the first, high-temperature water is used as the input cleaning solution. Alternatively, in the first high-pressure oscillating spray cleaning zone at the inlet of the turnover box / basket, hot water with alkali or hot water with edible alkali is used as the input cleaning solution, while in the second high-pressure oscillating spray cleaning zone or the high-temperature oscillating spray cleaning zone following the first, room-temperature water is used. This improves the initial cleaning effect of the turnover box / basket and enhances the overall cleaning effect of the multiple high-pressure oscillating spray cleaning zones, resulting in excellent cleaning effect and high cleaning quality.

[0007] Preferably, each set of swing-type spray frame mechanisms includes a swing-type spray frame and a swing-rotation drive structure. The swing-type spray frame is equipped with multiple spray pipes arranged in a parallel configuration. Each spray pipe has multiple spray heads.

[0035] In use, after the turnover boxes / baskets that need cleaning are conveyed into the spray cleaning area, a set of swing-type spray cleaning mechanisms is set up in the spray cleaning area in all four directions (up, down, left, and right) to form a four-sided swing high-pressure spray cleaning area without dead angles. In addition, multiple spray heads are distributed on each spray pipe, which can not only thoroughly clean the turnover boxes / baskets in all four directions, but also form the same high-pressure spray cleaning on the front and back inner and outer sides of the turnover boxes / baskets when they enter and leave the spray cleaning area. Thus, a more thorough 360-degree cleaning treatment without dead angles is achieved for the turnover boxes / baskets. In addition, in the first high-pressure swing spray cleaning zone, hot water with alkali or hot water with edible alkali is used as the input cleaning solution. In the second high-pressure swing spray cleaning zone or the high-pressure swing spray cleaning zone after the first high-pressure swing spray cleaning zone, room temperature water is used as the input cleaning solution. This allows different high-pressure swing spray cleaning zones to perform different cleaning solution treatments on the turnover boxes / baskets that need to be cleaned, resulting in turnover boxes / baskets with higher cleaning quality after the cleaning task is completed.
