Description

Technical Field

[0001] The present invention belongs to the technical field of automatic identification and data collection equipment, and more specifically, particularly relates to a precise scanning device for tracing the origin of edible agricultural products. Background Art

[0002] In modern agricultural product supply chain management, it is crucial to ensure the quality, safety and traceability of edible agricultural products. The establishment of an edible agricultural product traceability system can enable consumers to understand the entire process of agricultural product production, processing, transportation and sales, enhance consumer trust in the products, and also help regulatory authorities to effectively supervise the quality of agricultural products.

[0003] In the edible agricultural product traceability system, accurate scanning equipment is one of the key links. However, existing scanning equipment has many problems and shortcomings in practical applications.

[0004] Traditional scanning devices are often single-function and can only adapt to specific installation environments and scanning scenarios. For example, some scanning devices can only be fixed next to the conveyor belt and cannot flexibly cope with agricultural product packaging of different sizes and shapes, resulting in limited scanning angles and distances, affecting scanning accuracy and efficiency.

[0005] Some scanning equipment has poor adjustability and cannot be flexibly adjusted in height and horizontal position according to the size of the agricultural products, the height of the conveyor belt, and scanning requirements, making it difficult to achieve accurate scanning.

[0023] Preferably, both ends of the baffle are fixedly connected with rubber blocks.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When in use, the present invention can be hung on the side panels on both sides of the conveyor belt equipment, or it can be placed on the ground to scan and trace the agricultural products. The two modes of use are easy to switch and have sufficient stability.

[0026] 2. In the present invention, when using the installation method of hanging on the side plates on both sides of the conveyor belt equipment, the operator pulls the clamping plate to increase the gap between the clamping plate and the mounting seat, and then clamps the side plate of the conveyor belt equipment between the clamping plate and the mounting seat, loosens the clamping plate, and clamps the side plate between the clamping plate and the mounting seat under the elastic force of spring 1. Due to the presence of spring 1, the mounting seat can be clamped on side plates of different thicknesses, thereby improving applicability.

[0027] 3. When using the installation method of hanging on the side panels on both sides of the conveyor belt equipment, use the elastic force of spring 2 to make the base frame press against the bottom surface of the base frame, and then turn the limit nut to further clamp the side panels with the clamping plate and the mounting seat, so that the mounting seat is close to the side panels, and cooperate with the bottom limit of the base frame to make the mounting seat close to the side panels and maintain a stable position, which is not easy to shake or lose stability, and is easy to install and operate.

[0028] 4. After hanging the mounting base, release the limit on the longitudinal rod by turning the positioning screw. By moving the longitudinal rod up and down, the height of the barcode scanner can be adjusted to the most suitable height according to different agricultural products to achieve the effect of accurate scanning.

[0029] 5. Release the limit on the transverse rod by turning the adjusting screw on the sleeve block. Adjust the horizontal position of the scanner by adjusting the position of the transverse rod. It is also convenient to disassemble and assemble the transverse rod to further improve the scanning accuracy.

[0030] 6. Since the rotation axes of the adjustment rod and the longitudinal rod are different, when the positioning screw is connected to the longitudinal rod, the rotating rod acts as a limiter to keep the longitudinal rod in a vertical state, so that the longitudinal rod will not shake after the mounting base is fixed in position during the scanning process.

[0031] 7. When agricultural products are transported without using conveyor belt equipment, rotate the positioning screw to disengage it from the threaded positioning groove. At this time, the adjusting rod is deflected with the shaft rod as the axis. The mounting seat, adjusting rod and longitudinal rod form a triangular structure with good stability. At this time, the mounting seat can be placed on the ground as a base so that the barcode scanner can be suspended for scanning. The mounting seat and longitudinal rod are made of heavier metal, and the transverse rod is made of harder plastic to avoid tipping over of the barcode scanner to the greatest extent.

[0032] 8. When encountering agricultural products with large packaging volume, the transverse rod needs to be moved to a position away from the longitudinal rod for scanning. The operator pulls out the bottom frame until the strip groove is exposed, and then pushes the blocking bar in the strip groove to make it perpendicular to the strip groove. At this time, the bottom frame is released, and the bottom frame retracts under the tension of spring 2 until it is blocked by the blocking bar. At this time, the bottom frame can remain separated from the mounting base, thereby achieving the effect of increasing the bottom support range, as shown in the figure, thereby further improving stability and avoiding the situation where the mounting base is not stable enough when the scanner is far away from the longitudinal rod.

[0033] 9. When the mounting base is installed by hanging on the side panels, the base frame and the clamping plate respectively play the role of pressing the bottom and clamping the side panels. When the mounting base is placed on the ground, the bottom surfaces of the base frame and the clamping plate are flush and will not affect the level of the mounting base. The base frame and the clamping plate play different roles in different installation methods.

[0034] 10. Many agricultural products are picked, packed and shipped directly from the planting site. Therefore, the barcode scanner often needs to be placed on uneven ground. In this case, you can use the through slot to slide the longitudinal rod downward so that the bottom of the longitudinal rod is inserted into the ground. With the contact between the mounting base and the ground, the barcode scanner can be stably placed on the ground, further improving the stability of agricultural product traceability scanning.

When the installation method of hanging on the side plates on both sides of the conveyor belt device 1 is used, the operator pulls the clamping plate 19 to increase the gap between the clamping plate 19 and the mounting seat 2, and then clamps the side plate of the conveyor belt device 1 between the clamping plate 19 and the mounting seat 2, loosens the clamping plate 19, and clamps the side plate between the clamping plate 19 and the mounting seat 2 under the elastic force of the spring 1 23. Due to the existence of the spring 1 23, the mounting seat 2 can be clamped on side plates of different thicknesses, thereby improving applicability;

[0051] A shaft rod 14 is fixedly connected between the two adjusting rods 5, and the shaft rod 14 is rotatably sleeved with the two fixing seats 13. The opposite surfaces of the two adjusting rods 5 are respectively fitted with the opposite surfaces of the two fixing seats 13. A rotating rod 18 is also provided between the two adjusting rods 5. The two adjusting rods 5 are provided with connecting grooves 16, wherein both ends of the rotating rod 18 are fixed with connecting pieces 17, and the two ends of the rotating rod 18 are rotatably connected with the two connecting grooves 16 through the two connecting pieces 17, and the middle part of the rotating rod 18 is threadedly sleeved with a positioning screw 15;

[0052] The base frame 3 is an L-shaped frame, and two extension rods 24 are fixedly connected to the base frame 3. Each extension rod 24 is movably sleeved with a spring 25, and the end of each extension rod 24 is fixedly connected with a baffle 26, wherein the two extension rods 24 are movably sleeved with two clamping rings 8 respectively. After the side plate of the conveyor belt device 1 is clamped between the clamping plate 19 and the mounting seat 2, the base frame 3 is pulled down to make the base frame 3 abut against the bottom of the side plate, and the elastic force of the spring 25 is used to make the base frame 3 abut against the bottom surface of the base frame 3, and then the clamping plate 19 and the mounting seat 2 are further clamped to the side plate by rotating the limiting nut 22, so that the mounting seat 2 is close to the side plate, and the bottom limit of the base frame 3 is cooperated to make the mounting seat 2 close to the side plate and keep the position stable, not easy to shake and lose stability, and convenient installation and operation;

[0053] The extension rod 24 on the right side is provided with a strip groove 29, a stopper 28 is provided in the strip groove 29, and the middle part of the stopper 28 is rotatably connected to the middle part of the strip groove 29, and a vertical groove 35 and an equidistant threaded positioning groove 36 are provided on the longitudinal rod 4, the lower end of the longitudinal rod 4 is stuck in the rod groove 7, the fixed rod 10 in the rod groove 7 is stuck in the vertical groove 35, and the end of the positioning screw 15 is threadedly sleeved with the threaded positioning groove 36, wherein a collar 34 is movably sleeved on the upper end of the longitudinal rod 4, an adjusting screw is threadedly sleeved on the collar 34, a sleeve block 33 is also fixedly connected to the collar 34, and an adjusting screw is also threadedly sleeved on the sleeve block 33, the transverse rod 30 is movably sleeved with the sleeve block 33, and the transverse rod 30 is provided with equidistant holes, the adjusting screw on the sleeve block 33 is sleeved with the hole on the transverse rod 30, and the sliding sleeve 31 It is fixedly connected to the bottom of the barcode scanner 32, and the sliding sleeve 31 is sleeved on the tail of the transverse rod 30. The sliding sleeve 31 is threadedly sleeved with a tightening screw. The spring 25 is located between the clamping ring 8 and the baffle 26. Both ends of the baffle 28 are fixedly connected with rubber blocks 27. When the conveyor belt device 1 is not used for conveying agricultural products, the positioning screw 15 is rotated to disengage it from the threaded positioning groove 36. At this time, the adjusting rod 5 is deflected with the shaft rod 14 as the axis. During the deflection, the tail of the adjusting rod 5 is rotated into the inclined groove 6 until it is resisted by the groove surface of the inclined groove 6. At this time, the longitudinal rod 4 can be moved to the highest point and then deflected to be perpendicular to the mounting seat 2. The longitudinal rod 4 is moved down so that its bottom is inserted into the through groove 37, and then the positioning screw 15 is used to fix the longitudinal rod 4 and the rotating rod 18 together again. At this time, the state of the mounting seat 2 and the longitudinal rod 4 is as follows Fig. 9 As shown, the mounting seat 2, the adjustment rod 5 and the longitudinal rod 4 form a triangular structure with good stability. At this time, the mounting seat 2 can be placed on the ground as a base so that the barcode scanner 32 can be suspended for scanning. The mounting seat 2 and the longitudinal rod 4 are made of heavier metal, and the transverse rod 30 is made of plastic with higher hardness, which can prevent the barcode scanner 32 from tipping over to the greatest extent;

[0054] When encountering agricultural products with a large packaging volume, the transverse rod 30 needs to be moved to a position away from the longitudinal rod 4 for scanning and use. The operator pulls out the bottom frame 3 until the strip groove 29 is exposed, and then pushes the blocking bar 28 in the strip groove 29 to make it perpendicular to the strip groove 29. At this time, the bottom frame 3 is released, and the bottom frame 3 retracts under the pulling force of the spring 25 until it is blocked by the blocking bar 28. At this time, the bottom frame 3 can remain separated from the mounting seat 2, thereby achieving the effect of increasing the bottom support range. Fig.10 As shown, the stability is further improved to avoid the situation that the mounting base 2 is not stable enough when the barcode scanner 32 is far away from the longitudinal rod 4. The bottom frame 3 and the clamping plate 19 respectively play the effect of pressing against the bottom and clamping the side plate when the mounting base 2 is installed by hanging on the side plate. When the mounting base 2 is placed on the ground, the bottom surfaces of the bottom frame 3 and the clamping plate 19 are flush, which will not affect the level of the mounting base 2. The bottom frame 3 and the clamping plate 19 play different roles in different installation methods;

[0055] After hanging the mounting base 2, the limit on the longitudinal rod 4 is released by rotating the positioning screw 15. The longitudinal rod 4 is moved up and down, and the height of the scanner 32 is adjusted according to the different agricultural products so that the scanner 32 is at the most suitable height to achieve the effect of accurate scanning. The limit on the transverse rod 30 is released by rotating the adjusting screw on the sleeve block 33. The horizontal position of the scanner 32 is adjusted by adjusting the position of the transverse rod 30. At the same time, it is convenient to disassemble and assemble the transverse rod 30, further improving the accuracy of scanning. Since the adjustment rod 5 and the longitudinal rod 4 have different rotation axes, when the positioning screw 15 is connected to the longitudinal rod 4, the rotating rod 18 plays a limiting role, so that the longitudinal rod 4 remains in a vertical state, so that the longitudinal rod 4 will not shake after the mounting base 2 is fixed in position during the scanning process.

[0056] Working principle: When in use, the present invention can be hung on the side panels on both sides of the conveyor belt device 1, or it can be placed on the ground to scan and trace the source of agricultural products. The two usage modes are easy to switch and have sufficient stability;

[0057] When using the installation method of hanging on the side plates on both sides of the conveyor belt device 1, the operator pulls the clamping plate 19 to increase the gap between the clamping plate 19 and the mounting seat 2, and then clamps the side plate of the conveyor belt device 1 between the clamping plate 19 and the mounting seat 2, loosens the clamping plate 19, and clamps the side plate between the clamping plate 19 and the mounting seat 2 under the elastic force of the spring 1 23. Due to the existence of the spring 1 23, the mounting seat 2 can be clamped on side plates of different thicknesses, thereby improving applicability;

[0058] After the side plate of the conveyor belt device 1 is clamped between the clamping plate 19 and the mounting seat 2, the bottom frame 3 is pulled down to make the bottom frame 3 against the bottom of the side plate, and the bottom frame 3 is pressed against the bottom surface of the bottom frame 3 by the elastic force of the spring 25, and then the clamping plate 19 and the mounting seat 2 are further clamped to the side plate by rotating the limiting nut 22, so that the mounting seat 2 is close to the side plate, and the bottom limit of the bottom frame 3 is cooperated to make the mounting seat 2 close to the side plate and keep the position stable, not easy to shake and lose stability, and the installation operation is convenient;

[0059] After the mounting base 2 is hung, the positioning screw 15 is rotated to release the limit of the longitudinal rod 4, and the longitudinal rod 4 is moved up and down to adjust the height of the scanner 32 according to the unused agricultural products so that the scanner 32 is at the most suitable height to achieve the effect of accurate scanning;

[0060] The limit of the transverse rod 30 is released by rotating the adjusting screw on the sleeve block 33. The horizontal position of the barcode scanner 32 is adjusted by adjusting the position of the transverse rod 30. At the same time, the transverse rod 30 is easily disassembled and assembled, thereby further improving the scanning accuracy.

[0061] Since the rotation axes of the adjustment rod 5 and the longitudinal rod 4 are different, when the positioning screw 15 is connected to the longitudinal rod 4, the rotating rod 18 plays a limiting role, so that the longitudinal rod 4 remains in a vertical state, so that the longitudinal rod 4 will not shake after the mounting seat 2 is fixed in position during the scanning process;

[0062] When the conveyor belt device 1 is not used for conveying agricultural products, the positioning screw 15 is rotated to disengage the threaded positioning groove 36. At this time, the adjusting rod 5 is deflected with the shaft rod 14 as the axis. During the deflection, the tail of the adjusting rod 5 is rotated into the inclined groove 6 until it is supported by the groove surface of the inclined groove 6. At this time, the longitudinal rod 4 can be moved to the highest point and then deflected to be perpendicular to the mounting seat 2. The longitudinal rod 4 is moved down so that its bottom is inserted into the through groove 37, and then the positioning screw 15 is used to fix the longitudinal rod 4 and the rotating rod 18 together again. At this time, the state of the mounting seat 2 and the longitudinal rod 4 is as follows. Fig. 9 As shown, the mounting seat 2, the adjustment rod 5 and the longitudinal rod 4 form a triangular structure with good stability. At this time, the mounting seat 2 can be placed on the ground as a base so that the barcode scanner 32 can be suspended for scanning. The mounting seat 2 and the longitudinal rod 4 are made of heavier metal, and the transverse rod 30 is made of plastic with higher hardness, which can prevent the barcode scanner 32 from tipping over to the greatest extent;

[0063] When encountering agricultural products with a large packaging volume, the transverse rod 30 needs to be moved to a position away from the longitudinal rod 4 for scanning and use. The operator pulls out the bottom frame 3 until the strip groove 29 is exposed, and then pushes the blocking bar 28 in the strip groove 29 to make it perpendicular to the strip groove 29. At this time, the bottom frame 3 is released, and the bottom frame 3 retracts under the pulling force of the spring 25 until it is blocked by the blocking bar 28. At this time, the bottom frame 3 can remain separated from the mounting seat 2, thereby achieving the effect of increasing the bottom support range. Fig.10As shown, the stability is further improved to avoid the situation where the mounting base 2 is not stable enough when the barcode scanner 32 is far away from the longitudinal rod 4;

[0064] The base frame 3 and the clamping plate 19 respectively play the role of pressing against the bottom and clamping the side panels when the mounting base 2 is installed in a suspended manner on the side panels. When the mounting base 2 is placed on the ground, the bottom surfaces of the base frame 3 and the clamping plate 19 are flush and will not affect the level of the mounting base 2. The base frame 3 and the clamping plate 19 play different roles in different installation methods.

[0065] Many agricultural products are picked, packed and shipped directly from the planting site, so the barcode scanner 32 often needs to be placed on uneven ground. In this case, the through groove 37 can be used to slide the longitudinal rod 4 downward so that the bottom of the longitudinal rod 4 is inserted into the ground. Combined with the contact between the mounting base 2 and the ground, the barcode scanner 32 can be stably placed on the ground, further improving the stability of agricultural product traceability scanning.

Many modifications and variations will be apparent to those of ordinary skill in the art.
