Detailed Implementation

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] Please see the appendix Figure 1-7 The purpose of this embodiment is to provide an intelligent sampling device, including: a barrier gate 33 installed on the unloading lane 1; a sampling component 34 installed on the gate arm 332 of the barrier gate 33; a linear module 344 in the sampling component 34 connected to the gate arm 332; a first slider 3442 in the linear module 344 fixedly connected to the hopper 343; a support beam 3432 fixedly installed on one side of the hopper 343; and multiple pressure sensors 3434 evenly arranged on the support beam 3432. The hopper 343 reciprocates under the drive of the linear module 344, and can sample the grain poured out of the vehicle 2 in real time. The grain poured out of the vehicle 2 flows in a parabolic trajectory and has a certain thickness. The pressure sensors 3434 can detect the position of the grain poured out of the vehicle 2, ensuring that sufficient grain sample enters the hopper 343. Under normal circumstances, the thickness of the grain can cover 1-2 pressure sensors 3434.

[0027] Specifically, the linear module 344 is equipped with a protective plate 341. A support rod 3411 is provided at each end of the protective plate body 3412, and the two support rods 3411 are fixed to both ends of the linear module 344. Multiple contact sensors are provided on the protective plate body 3412. If the vehicle 2 is too close to the protective plate body 3412, the contact sensors on the protective plate body 3412 will be triggered, prompting the vehicle 2 to move. It should be noted that the first slider 3442 is slidably connected to the first slide rail 3441 in the linear module 344, and the first slide rail 3441 is fixed to the brake lever 332. A second protective shell 32 is provided on the linear module 344, which prevents grain and dust from entering the linear module 344. Preferably, the first slider 3442 can be driven by a synchronous belt, and the second motor 3443 can drive the synchronous pulley to move, thereby moving the synchronous belt. The synchronous belt is fixedly connected to the first slider 3442. Alternatively, the first slider 3442 can be driven by a lead screw and nut pair. In this case, the first slider 3442 is a nut slider. Those skilled in the art can select the driving method of the linear module 344 according to their needs.

[0028] Furthermore, the hopper 343 is fixedly connected to the front end 3421 of the first cable chain 342 via the first support plate. The first cable chain 342 is disposed in the first protective shell 31, which is fixed to the gate arm 332. During the reciprocating motion of the hopper 343, the front end 3421 of the first cable chain is pulled, causing the first cable chain 342 and its internal flexible guide tube to move with the hopper 343.

[0029] In this embodiment, the gate arm 332 is rotatably connected to the support 336. A first motor 334 is provided on one side of the support 336 via a first motor mount. The first motor 334 drives the gate arm 332 to rotate. A counterweight 335 is fixedly connected to the end of the gate arm 332 near the first motor 334 to maintain the balance of the entire intelligent sampling device.

[0030] Furthermore, the support 336 is fixedly connected to the connecting seat 354 of the base assembly 35, and the connecting seat 354 is slidably connected to the second slide rail 352 of the base body 351 via the second slider 353. The base body 351 is also provided with a rack; the connecting seat 354 is equipped with a third motor 355 via a third motor mount, and the output end of the third motor 355 is provided with a drive gear, which meshes with the rack; the third motor mount is connected to the front end 3561 of the second drag chain 356 via a second support plate 357. The third motor 355 causes the brake lever 332 to move along the second slide rail 352 via a gear and rack structure. The second slide rail 352 is perpendicular to but not coplanar with the first slide rail 3441. When the third motor 355 moves with the connecting seat 354, it pulls the front end 3561 of the second drag chain, causing the second drag chain 356 and its internal flexible guide tube to move with the connecting seat 354. It is worth mentioning that the discharge port 3433 of the hopper 343 is connected to a flexible guide tube, which passes through the front end 3421 of the first drag chain, the inside of the first drag chain 342, the rear end 3422 of the first drag chain, the front end 3561 of the second drag chain, the second drag chain 356, and the rear end 3562 of the second drag chain in sequence.

[0031] Finally, a screen 14 is installed on the unloading lane 1, with a first baffle 11 and a second baffle 12 on both sides of the screen 14. The first baffle 11 and the second baffle 12 can reduce the degree of grain splashing. A temporary storage bin is provided at the bottom of the screen 14. This intelligent sampling device is connected to a detection device, which includes a detection analyzer 4. The suction port 41 of the detection analyzer 4 is connected to the end of the flexible guide tube.

[0032] In operation, the barrier gate 33 is first opened, and vehicle 2 drives into the unloading lane 1 to the designated position. The barrier gate 33 then returns to its initial horizontal position, maintaining a suitable distance between the rear of vehicle 2 and the guard plate body 3412. Next, the vehicle 2's door 21 opens, dumping the grain. At this time, the hopper 343 begins to reciprocate for grain sampling. During sampling, a pressure sensor on one side of the hopper 343 detects the position of the parabolic grain of a certain thickness that is dumped out. By moving the barrier gate 33 back and forth, the relative position of the hopper 343 and the dumped grain can be adjusted to ensure that a sufficient amount of grain sample enters the inlet 3431 of the hopper 343. Unsampled grain passes through the screen 14 and enters the temporary storage bin. The grain entering the hopper 343 is drawn into the analyzer 4 through the suction inlet 41 under suction force, completing the grain sample index detection. This intelligent sampling device can accurately determine the position of the grain dumped from the vehicle and collect grain samples in real time through the uniform reciprocating motion of the hopper, improving sampling efficiency and enabling the identification of impurities mixed in with the grain.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
