[0015] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0016] Example 1 like Figures 1 to 6 As shown, this embodiment provides a smart grain sampling device, including a sampling frame 11. The frame 11 adopts a steel structure frame, and two sets of parallel guide rails 12 are horizontally mounted on the top. A slider 13 is slidably connected to the guide rails 12, and the slider 13 is driven by a drive motor 131 to move along the guide rails 12. Specifically, the drive motor 131 is fixed to the side of the slider 13, and its output shaft is connected to a gear 132. The inner sides of the two sets of guide rails 12 are provided with racks 121, and the gears 132 mesh with the racks 121. The reciprocating motion of the slider 13 is realized by controlling the forward and reverse rotation of the drive motor 131. The bottom of the slider 13 is provided with a V-groove 133, and an inverted V-shaped platform 122 is welded on the guide rails 12, forming a sliding fit with the V-groove 133 of the slider 13 to ensure the stability of the slider movement and prevent derailment. This utility model, by setting guide rails and sliders on the sampling frame, allows the sampling robotic arm to slide on the guide rails, thereby realizing flexible adjustment of the sampling position. This design greatly improves the coverage and accuracy of sampling, avoiding the problem of insufficient sample representativeness caused by traditional fixed-location sampling.
[0017] Sampling robotic arm 14 and turntable structure A turntable 19 is mounted on the slider 13, and the turntable 19 is rotatably connected to the slider 13 and driven to rotate by a rotating motor (not shown) fixed inside the slider. The connection can be made using a bearing connection. One end of the sampling robotic arm 14 is vertically fixed to the turntable 19, and the other end extends to the sampling area. A sampling pipette 15 is connected to the end of the robotic arm 14. The pipette 15 is a hollow metal tube with multiple sets of suction holes evenly distributed vertically at its end to achieve simultaneous sampling at different depths.
[0018] Anti-breakage unloading and mixing system The sampling pipette 15 is connected to the anti-breakage unloader 18 via a flexible conduit 17. Both the anti-breakage unloader 18 and the mixer 16 are fixed to the slider 13 and move with it. They are used to sample grains at different locations. The inner wall of the mixer 18 is lined with a rubber anti-collision layer to cushion the impact of falling grains and reduce breakage. The outlet of the anti-breakage unloader 18 faces the mixer 16 below. The mixer 16 includes a receiving hopper 161 and a sample distributor 162. The receiving hopper 161 receives grains from the unloader 18 and then distributes them through the sample distributor 162. The sample distributor 162 has four sets of discharge ports. Two sets of discharge ports are connected to the inspection suction hopper (for grain impurity level detection) via pipes, while the other two sets of discharge ports face directly towards the grain delivery vehicle (for sample backfilling). The four sets of discharge ports are arranged in a ring-shaped, alternating pattern to ensure uniform sample distribution. This utility model features a combined design of a sample mixer and a sample divider, which enables rapid mixing and separation of samples after collection, improving the efficiency of sample processing. The sample divider has two outlets, which are connected to the test suction hopper and the feed cart, respectively, realizing rapid sample diversion, reducing intermediate steps and improving work efficiency.
[0019] Workflow Mobile positioning: The drive motor 131 drives the slider 13 to move along the guide rail 12 to the target area, while rotating the motor to adjust the angle of the turntable 19, so that the sampling robot arm 14 is aligned with a specific position of the grain delivery vehicle.
[0020] Sampling and conveying: The sampling pipette 15 is inserted into the grain pile, and the grain is adsorbed by negative pressure. The grain enters the anti-breakage unloader 18 through the pipeline 17, and falls into the receiving hopper 161 after buffering.
[0021] Mixing and separating: Grains in the receiving hopper 161 are distributed proportionally to the inspection port and the backfill port by the sampler 162, completing automatic mixing and separation.
[0022] Example 2 In another embodiment, the sampler 162 is configured with six sets of discharge ports, three sets connected to inspection ports, and three sets connected to backfill ports, further optimizing the uniformity of sample distribution. The anti-breakage unloader 18 has its anti-collision layer replaced with polytetrafluoroethylene material to enhance wear resistance.
[0023] Technical effect Driven by guide rails and rack and pinion gears, combined with the rotation of the turntable, precise positioning and sampling in three-dimensional space are achieved; the inverted V-shaped stage and V-groove work together to improve movement stability and avoid jamming; the combination design of the anti-breakage unloader and the sampler reduces grain damage and improves mixing efficiency; the vertically distributed suction holes ensure sampling depth coverage and improve sample representativeness.
[0024] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
