Description

Technical Field

[0001] This invention relates to an agricultural product grading machine, and more particularly to a checkweigher device for an agricultural product grading machine. Background Technology

[0002] Post-harvest weight grading of agricultural products is a crucial production step in standardizing agricultural product specifications. Grading agricultural products by size after harvest improves product quality and reduces uneven weight distribution during packaging, preventing damage to larger products during storage, transportation, and handling. Previously, agricultural product grading was done manually according to diameter, resulting in low efficiency and poor quality. To improve grading efficiency and quality, starting in 1950, countries such as the United States, the Netherlands, and France invented chain-mounted cup-type agricultural product weight grading machines, meeting the weight grading needs of some agricultural products and improving efficiency and product quality. However, when using chain-mounted cup-type agricultural product weight grading machines, some less resistant products suffer punctures during the feeding and grading process. To address this technical problem of damage during grading, Japan invented the agricultural product movable-plate grading machine (Japanese Patent Application Publication No. 2006-175443, Agricultural Product Sorting Device). The agricultural product tray grading machine uses a conveyor belt to load trays for grading. This means the trays carrying agricultural products are graded onto each grade track, with the trays colliding directly with each other, thus avoiding damage caused by collisions. This successfully solves the problem of damage to agricultural products during grading. However, existing weighing devices for agricultural product tray grading machines use belt checkweighers for weight grading. These belt checkweighers consist of a belt, motor, and weighing sensor integrated into one unit. Vibration during motor and belt operation affects the weighing accuracy of the weighing sensor, leading to large weighing errors in the agricultural product tray grading machine, reduced uniformity of grading, and increased positive and negative errors in the net weight of agricultural product packaging boxes. For some lightweight agricultural products, existing live-plate grading machines are unable to sort them due to large weighing errors. For example, cherries: Red Lantern cherries weigh 8-13g each, with three sorting grades: large (13-12g), medium (12-10g), and small (10-8g). Existing live-plate grading machines have a weighing error of ≤±5g. Such a large error makes them unsuitable for grading lightweight and expensive agricultural products like cherries, strawberries, and sea cucumbers.

[0003] Technical problems to be solved

[0004] This invention addresses the problems of large weighing errors and low weight sorting accuracy in existing agricultural product grading machines using belt checkweighers. By employing a non-powered weighing slide, this invention solves the technical problem of increased weighing errors caused by vibrations from the belt and motor affecting the weighing accuracy of the checkweigher due to the integrated structure of the belt, motor, and weighing sensor in existing belt checkweighers. This improves the grading accuracy of agricultural product grading machines.

[0005] The present invention relates to a movable sliding checkweigher device, which consists of a conveyor, a weighing slide, an output machine, and a device frame. The conveyor, weighing slide, and output machine are fixedly connected to the same device frame platform in the aforementioned order and in the same direction of operation. The conveyor belt of the conveyor, the upper surface of the weighing slide, and the output belt of the output machine must be kept at the same horizontal level, with an appropriate gap at the connection point. This ensures that the conveyor belt uses its inertia to send the movable disc carrying agricultural products onto the weighing slide. The movable disc carrying agricultural products is weighed as it passes through the weighing slide. Then, under the action of inertia, the movable disc carrying agricultural products moves to the output belt of the output machine and is picked up by the output machine, thus completing the checkweighing process.
