Description

Technical Field

[0001] This invention relates to the field of data acquisition technology, specifically to a rapid scanning device for agricultural product traceability with anti-fouling and cleaning functions. Background Technology

[0002] With increasing societal focus on food safety, the construction and improvement of agricultural product traceability systems have become a core component of food quality and safety supervision. Agricultural product traceability enables information tracking throughout the entire process from planting / breeding, harvesting / slaughtering, processing, logistics to sales, effectively ensuring food safety while satisfying consumers' right to know and regulatory authorities' need for precise oversight. Traceability scanning equipment, as the core terminal device in the agricultural product traceability system, plays a crucial role in traceability code identification, data collection, and uploading. It is widely used in various scenarios such as field harvesting points, agricultural product processing lines, wholesale market conveyor belts, farmers' market stalls, and cold chain storage areas. Its scanning efficiency, identification accuracy, and scenario adaptability directly determine the operational efficiency of the agricultural product traceability system.

[0003] To adapt to the usage requirements of different traceability scenarios, several adjustable and multi-installation agricultural product traceability scanning devices have emerged in the existing technology. Patent CN119538950A discloses a precise scanning device for edible agricultural product traceability, including a barcode scanner and a conveyor belt for transporting agricultural products. A base mechanism is mounted on the side of the conveyor belt, and a support frame mechanism is mounted on the barcode scanner. The base mechanism includes a mounting seat, a clamping plate, a base frame, and two adjusting rods. The support frame mechanism includes a longitudinal rod, a transverse rod, and a sliding sleeve. The mounting seat has a pair of circular grooves, a pair of circular grooves, a pair of inclined grooves, and a pair of bottom grooves. The middle part of the surface is also provided with a rod groove, and the middle part of the rod groove is provided with a through groove. The middle part of the rod groove is also fixedly connected to a fixed rod. The above-mentioned agricultural product scanning equipment realizes a dual installation mode of conveyor belt suspension and ground placement. The height and horizontal position of the barcode scanner can be adjusted by adjusting rods, support frames and other structures, which solves the problems of single installation method and poor adjustability of traditional scanning equipment, and improves the scene adaptability of the equipment to a certain extent. However, in combination with the actual application characteristics of agricultural product traceability, the existing agricultural product traceability scanning equipment still has many technical defects and pain points in use, and cannot meet the needs of rapid and accurate traceability in polluted and complex environments.

[0004] The various application scenarios for agricultural product traceability are characterized by high levels of contamination, dust, and humidity. Harvesting sites in the fields are prone to accumulating soil, fruit and vegetable juices, and leaf residue; processing lines and conveyor belts are susceptible to residues of agricultural products and water stains; and cold chain storage areas are prone to condensation. These contaminants easily adhere to the scanning window surface of barcode scanners, causing blurred barcode recognition and scanning failures. Existing agricultural product traceability scanning equipment lacks a dedicated anti-fouling and cleaning structure for the scanning window, using only ordinary transparent glass as the scanning window substrate. This makes it easy for stains to adhere and difficult to clean, resulting in a lack of core anti-fouling and cleaning functions in agricultural product scanning equipment, significantly reducing accuracy in contaminated environments. Therefore, there is an urgent need for a rapid agricultural product traceability scanning device with anti-fouling and cleaning functions to solve the aforementioned problems.

[0058] The working principle of this invention is as follows:

[0059] The scanning mechanism 1 is equipped with centrally symmetrical support mechanisms 2 on both sides. The support mechanisms 2 on both sides of the scanning mechanism 1 are set separately, so the lateral spacing between the two support mechanisms 2 can be reasonably arranged according to the span required by the actual working area. The scanning chamber 101 is connected to the slide block 106 and the rail plate 209 on both sides, so that the slide block 106 on one side and the rail 208 on one side can independently control the movement of the scanning mechanism 1, thereby adapting and adjusting the width required by the working area. At the same time, the height can be reasonably raised by the inner column 205 and locked by the limiting hole 204, so as to adapt and adjust the height required by the working area. The lower surface of the foot 202 is equipped with rollers 203 on both sides, so that it can be moved according to actual needs, thereby ensuring the compatibility between the equipment and the working area and improving the flexibility of the equipment.

[0060] With the support mechanisms 2 symmetrically arranged on both sides of the scanning mechanism 1, the support mechanisms 2 can be erected on both sides of the working area, whether for a conveyor belt type working environment or a fixed working environment, and provide synchronous or individual support for the scanning mechanism 1, without the need to change or switch the connection structure according to the working environment; at the same time, the support mechanism 2 and the scanning mechanism 1 form a unified connection, which can ensure the overall structural balance of the equipment during operation, thereby improving the stability of the equipment operation.

[0061] The foot plate 210 is released from its limit by the pin 211 and the limiting hole 204, allowing the column 201 to slide up and down. When the foot plate 210 moves upward, the plate 213 fits against the foot 202, allowing the anti-slip pad 214 to be suspended in the air. The support mechanism 2 is supported and controlled by the roller 203. When the foot plate 210 moves downward, the anti-slip pad 214 fits against the ground, creating resistance, thereby releasing the support and control function of the roller 203. The friction between the anti-slip pad 214 and the ground ensures the stability of the equipment.

[0062] The scanning mechanism 1 is connected to the air jet mechanism 3 through the disc assembly, and can drive the frame ring 301 to rotate through the starter 107. This allows the air jet assembly, which is hinged to the support frame 303 through the torsion spring shaft, to remove dirt from the surface of the protective cover 104, thereby improving the cleanliness of the protective cover 104 surface and thus improving the scanning accuracy.

[0063] The actuating ball 307 of the air spray assembly fits against the lower end face of the cylinder frame 109, and the lower end face of the cylinder frame 109 is wavy. Therefore, when the frame ring 301 drives the air spray assembly to rotate around the protective cover 104, the actuating ball 307 oscillates up and down along the lower end face of the cylinder frame 109, so that the air nozzle 305 blows along the surface of the protective cover 104 with the connecting ball 304 as the axis, thus fully covering the surface of the protective cover 104 and improving the comprehensiveness of the equipment's self-cleaning.

[0064] In the early stage of scanning, the scanning mechanism 1 and the cleaning mechanism 4 are positioned opposite each other by moving and adjusting the support mechanism 2. The rinsing head 409 draws clean water from the first water tank 401 through the first clean water pipe 406, the second clean water pipe 411 and the water pump 412 to rinse the surface of the protective cover 104. Through the insertion of the vertical column 302 and the positioning hole 405, the rotation of the frame ring 301 drives the wiping blade 408 to rotate along the lower surface of the protective cover 104. Then, the flexible scraper 410 further scrapes away the dirt on the surface of the protective cover 104, thereby further improving the cleaning effect. The cleaning mechanism 4 automatically cleans the scanning mechanism 1, improving the working efficiency of the scanning equipment.

[0065] By designing the protective cover 104 as an arc surface, the flushing head 409 is used to flush the protective cover 104. Then, under the action of gravity, the sewage will roll down the protective cover 104 towards the center. With the collection tray 404 covering the protective cover 104, the sewage can be collected in the second water tank 402 through the collection tray 404 and sewage pipe 403. At the same time, with the comprehensive blowing of the air spray mechanism 3, the protective cover 104 can be quickly cleaned and dried without water stains, thereby improving the self-cleaning ability of the equipment.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
