Description

Technical Field

[0001] The present invention belongs to the technical field of grain quality detection, and specifically refers to a grain quality detection device. Background Art

[0002] As the basic material basis for human survival and development, the quality of grain is directly related to multiple important aspects such as food safety, agricultural economy, and social stability. In the process of grain production, storage, transportation, and trading, accurately evaluating grain quality is a key link to ensure the effective utilization of grain and protect the rights and interests of consumers. Traditional grain quality detection methods often have some limitations, and more efficient, accurate, and intuitive detection technologies are needed to meet the requirements of the modern grain industry.

[0003] When differentiating grain quality, it is often difficult to accurately distinguish quality indicators such as the plumpness of grain only by relying on traditional visual observation. There may be subtle differences in appearance between plump grain and shriveled grain. For some inexperienced inspectors or in large-scale inspection tasks, it is difficult to quickly and accurately judge the quality of grain only by direct visual inspection with the naked eye.

[0004] Although some existing physical or chemical detection methods can determine grain quality parameters to a certain extent, such as moisture content, nutrient components, etc., for an index like grain plumpness, which is relatively intuitive but has an important impact on the overall grain quality, there is a lack of a detection method that can simply, quickly, and intuitively present it. These traditional detection methods may require complex instrument equipment, a long detection cycle, and professional operators, which is not conducive to wide application in on-site environments such as grain production and warehousing. Summary of the Invention

[0005] In view of the above situation, to overcome the defects of the prior art, the present invention provides a grain quality detection device. According to the differences in the surface structure and internal pore structure between shriveled grain and plump grain, this difference will cause their different adsorption capacities when contacting dyes.

The alternately lifting, tumbling, and receiving dyeing mechanism, through the cooperation of the eccentric contact device and the receiving and dyeing transfer box, has multiple receiving and dyeing transfer boxes with gradually increasing heights. The rotation of the eccentric contact disk realizes the contact with the box body, causing the grains to rise and tumble for dyeing among multiple boxes, achieving all-round orderly transmission and tumbling dyeing.

In the quality highlighting device, the excess dye adsorption and highlighting component rotates the first roller, the second roller, and the adsorbed sponge wrapped around them in opposite directions to roll and adsorb the grains falling between them, removing the excess dyes on the grain surfaces and preventing dye dripping and contamination. In the anti-dripping collection part, the extrusion blanking plate can extrude and recover the adsorbed dyes while the adsorbed sponge rotates and adsorbs, avoiding the dripping of saturated dyes in the adsorbed sponge. The recovered dyes can be taken out through the discharge pipe. In the flat-laying observation device, the linkage trigger vibrating component is connected to the second gear, driving the trigger column to strike the vibrating plate. At the same time, the knocking plate on the rotating shaft periodically knocks the vibrating plate. The movement of the vibrating plate drives the flat-laying display board to vibrate under the action of the spring, making the grains falling on the flat-laying display board evenly spread out, facilitating the observation of the grain quality.

The observation frame 33 is provided on the detection vehicle 1. The tiling display board 34 is movably provided in the observation frame 33 through the spring 37. The vibration column 35 is provided at the center of the bottom wall of the tiling display board 34. The vibration plate 36 is provided below the vibration column 35. The linkage trigger vibration leveling member 38 is connected to the second gear 31. The linkage trigger vibration leveling member 38 includes a connecting rod 39, a trigger column 40, and a limiting rod 41. One end of the connecting rod 39 is eccentrically rotated on the second gear 31. The trigger column 40 is joined to the other end of the connecting rod 39.

[0028] When in use, the inspection vehicle 1 is moved to the grain pile to be inspected, and the obliquely inserted guide sampling tube 2 is aligned with the grain pile and inserted, so that the grain to be inspected falls into the obliquely inserted guide sampling tube 2, and under the action of the spiral guide plate 17, it falls into the dyeing guide groove 10 in an orderly manner, contacts the dyeing sponge 12 that absorbs dye by capillary action, and performs rolling dyeing, and the motor 16 is started. The rotation of the motor 16 drives the rotating shaft 14 to rotate, and the rotation of the rotating shaft 14 drives the eccentric top contact plate 15 to rotate, and the eccentric top contact plate 15 and the rotation touch the box body 8. The box body 8 rises and drives the grain that has fallen into the dyeing guide groove 10 and dyed to fall into the dyeing guide groove 10 of the next box body 8, and is turned over and dyed again, so as to achieve the goal of dyeing the grain. The technical effect of the all-round orderly transmission of the flipping dyeing is that at this time, the shriveled gaps of the dry grains will absorb more dyes, while the surface of the full grains will absorb less dyes, which makes it easier to observe and distinguish the quality of the grains. After dyeing, the grains fall onto the receiving slide plate 18 and fall between the adsorption sponges 24 through the blanking gap 21, and the motor 2 32 is started. The motor 2 32 rotates to drive the gear 1 30 to rotate, and the gear 1 30 rotates to drive the rotating roller 1 22 to rotate. The rotating roller 1 22 rotates to drive the adsorption sponge 24 wrapped thereon to rotate. The gear 1 30 rotates and drives the gear 2 31 to rotate at the same time. The gear 2 31 rotates to drive the rotating roller 23 to rotate. The rotating roller 23 rotates to drive the adsorption sponge 24 wrapped thereon to rotate. The two adsorption sponges 24 rotate towards each other, and then roll and adsorb the grains that fall thereon, and then adsorb the excess dye on the surface of the grains to prevent dripping and contamination, and will not adsorb the dye in the shriveled gaps, further increasing the color difference between full grains and shriveled grains, and improving the observation and distinction efficiency. The adsorbed grains fall onto the lead-out platform 20 and fall onto the flat spread board 34 through the discharge port 48. The extrusion blanking plate 28 can squeeze and recover the adsorbed dye while the adsorption sponge 24 rotates to adsorb, preventing the saturated dripping of the adsorbed dye in the adsorption sponge 24. The squeezed dye falls into the collection box 27 and can be taken out through the discharge pipe 29. The gear 2 31 rotates and drives the connecting rod 39 to rotate and rise. The connecting rod 39 rotates and rises The trigger column 40 is driven to rise and fall along the limit rod 41 to hit the vibration plate 36. The vibration plate 36 is struck and moved, driving the vibration column 35 to move. The movement of the vibration column 35 drives the spreading plate 34 to vibrate under the action of the spring 37, thereby spreading the grain fallen thereon evenly. The rotation of the rotating shaft 14 drives the knocking plate 43 to rotate at the same time. The rotation of the knocking plate 43 periodically knocks the vibration plate 36. The movement of the vibration plate 36 drives the vibration column 35 to move. The movement of the vibration column 35 drives the spreading plate 34 to vibrate up and down under the action of the spring 37, further making the grain falling on the spreading plate 34 more uniform, which is convenient for observing the grain quality. The above is the specific working process of the present invention. You can repeat this step next time you use it.
