[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figure 1-8 A multifunctional smart agricultural sorting scale includes a small warehouse 1 with a guide pipe. A loading and unloading trough 2 is fixedly opened on the surface of the small warehouse 1. A loading and unloading worktable 3 with a certain height is fixedly connected to the inner wall of the loading and unloading trough 2. The loading and unloading worktable 3 is used to provide a connecting platform for loading and unloading grains in the small warehouse 1. In this way, the buyer is outside and the shop owner is inside. The shop owner can directly use one end of the existing grain guide pipe with a valve to align with the loading and unloading worktable 3. The loading and unloading worktable 3 has a certain height, avoiding the need for handling.

[0035] A controller 4 is fixedly installed on the surface of the loading and unloading workbench 3.

[0036] Furthermore, in this embodiment, the controller 4 is also connected to the control system inside the small warehouse 1, thereby facilitating the linkage control between the grain weighing equipment and the small warehouse 1.

[0037] In order to achieve efficient and convenient weighing of grain particles, a loading and unloading drive mechanism is fixedly connected to the surface of the loading and unloading workbench 3. The loading and unloading drive mechanism includes a drive shaft 5, which is fixedly installed on the surface of the loading and unloading workbench 3 through bearings.

[0038] In order to assist in loading and unloading grains, a loading and unloading auxiliary mechanism is fixedly connected to the surface of the small warehouse 1. The loading and unloading auxiliary mechanism includes a fixed plate 6, and the surface of the fixed plate 6 is fixedly connected to the surface of the small warehouse 1.

[0039] One end of the drive shaft 5 passes through and extends to the lower surface of the loading / unloading worktable 3. A worm gear 501 is fixedly sleeved on one end of the drive shaft 5. A bearing seat 502 is fixedly connected to the lower surface of the loading / unloading worktable 3. The two bearing seats 502 are symmetrically distributed with the axis of the worm gear 501 as the center. A worm 503 is fixedly connected to the inner wall of the bearing seat 502 through the bearing.

[0040] The surface of the worm 503 meshes with the surface of the worm wheel 501. A drive motor 504 is fixedly installed on the lower surface of the loading and unloading worktable 3. The drive motor 504 is electrically connected to the controller 4 through wires. The output shaft of the drive motor 504 is fixedly connected to one end of the worm 503 through a coupling.

[0041] In order to drive and position the drive shaft 5, a connecting positioning disk 505 is fixedly connected to the other end of the drive shaft 5. The surface of the connecting positioning disk 505 is slidably connected to the surface of the loading and unloading worktable 3. A sensing block 506 is fixedly connected to the surface of the connecting positioning disk 505. The four sensing blocks 506 are arranged in a ring array with the axis of the connecting positioning disk 505 as the center.

[0042] A proximity sensor 507 is fixedly installed on the surface of the loading / unloading workbench 3. The proximity sensor 507 is electrically connected to the controller 4 via a wire.

[0043] Furthermore, in this embodiment, the output shaft of the drive motor 504 drives the worm 503 to rotate via a coupling. The surface of the worm 503 meshes with the surface of the worm wheel 501, causing the worm 503 to drive the worm wheel 501 to rotate, thereby driving the drive shaft 5 to rotate. While the drive motor 504 drives the drive shaft 5 to rotate, the drive shaft 5 drives the connecting positioning disk 505 to rotate. The sensing block 506 is fixedly connected to the surface of the connecting positioning disk 505 and rotates with the connecting positioning disk 505. During the rotation, the sensing block 506 approaches the proximity sensor 507. After the proximity sensor 507 detects the sensing block 506, it sends an electrical signal to the controller 4. The controller 4 controls the drive motor 504 to stop working, thereby performing positioning control when the drive motor 504 drives the drive shaft 5 to rotate.

[0044] A connecting pipe 508 is fixedly connected to the surface of the positioning plate 505. The surface of the connecting pipe 508 is funnel-shaped. An installation ring 509 is fixedly sleeved on the surface of the connecting pipe 508. The surface of the installation ring 509 is slidably connected to the inner wall of the upper and lower material troughs 2. The surface of the installation ring 509 extends into the interior of the small warehouse 1.

[0045] The surface of the mounting ring 509 is provided with a weighing box 510 with a weighing sensor at the bottom. Four weighing boxes 510 are arranged in a circular array with the axis of the mounting ring 509 as the center. Support blocks 511 are provided on both sides of the weighing box 510. Two support blocks 511 are symmetrically distributed with the axis of the weighing box 510 as the center. The surface of the support block 511 is fixedly connected to the surface of the mounting ring 509. After the feed tube is aligned with the weighing box 510, the valve is opened. After the grain enters, it is weighed by the weighing sensor at the bottom. After the specified weight is reached, the valve is closed.

[0046] The surface of the weighing box 510 is hinged to the surface of the support block 511 by a pin, and a counterweight block 512 is fixedly connected to the end of the weighing box 510 away from the support block 511.

[0047] A reinforcing plate 601 is fixedly connected to the surface of the fixed plate 6. The two reinforcing plates 601 are symmetrically distributed with the axis of the fixed plate 6 as the center. The surface of the reinforcing plate 601 is triangular in shape and is fixedly connected to the surface of the small warehouse 1.

[0048] A fixing post 602 is fixedly connected to the surface of the fixing plate 6. A fixing plate 603 is fixedly connected to one end of the fixing post 602. The surface of the fixing plate 603 is slidably connected to the inner wall of the connecting pipe 508. An annular functional groove 604 is fixedly opened on the surface of the fixing plate 603.

[0049] The inner wall of the annular functional slide 604 is provided with positioning support protrusions 605, and the four positioning support protrusions 605 are arranged in a ring array with the axis of the annular functional slide 604 as the center.

[0050] One end of the weighing box 510 extends above the fixed plate 603. The surface of the weighing box 510 is fixedly connected to the support column 606. The two support columns 606 are symmetrically distributed with the axis of the weighing box 510 as the center. One end of the support column 606 is fixedly provided with a rotating groove 607. The inner wall of the rotating groove 607 is slidably connected to a rotating ball 608. The surface of the rotating ball 608 extends to the surface of the support column 606. The surface of the rotating ball 608 is slidably connected to the inner wall of the annular functional groove 604.

[0051] Furthermore, during the rotation of the mounting ring 509 and the weighing box 510 driven by the drive motor 504, in order to prevent the grain particles from slipping out of the weighing box 510 due to the centrifugal force generated by the rotation, the support column 606 and the rotating ball 608 on the weighing box 510 slide from the positioning support protrusion 605 in the annular functional slide groove 604 to the inner bottom wall of the annular functional slide groove 604, so that the weighing box 510 is in an inclined state during the movement, preventing the grain particles from slipping out of the weighing box 510. After rotating ninety degrees, it moves to another positioning support protrusion 605, so that the weighing box 510 remains horizontal when loading and unloading the grain particles. After the conveyor belt comes out, the weighing box 510 tilts downward, and the grain particles can be poured out by utilizing the height difference of the worktable 3. The buyer outside can use this height difference to place the container at the bottom, and the grain particles will naturally be guided into the container.

[0052] By setting up an auxiliary loading and unloading mechanism, during use, the annular functional groove 604 opened on the surface of the fixed plate 603, and the positioning support protrusion 605 set in the annular functional groove 604, form a height difference with the inner bottom wall of the annular functional groove 604. During the movement of the four weighing boxes 510, the weighing boxes 510 are in an inclined state, thereby preventing the grain particles from slipping out of the weighing boxes 510 during the movement of the weighing boxes 510.

[0053] The surface of the fixed column 602 is slidably sleeved with the functional tube 609. The surface of the functional tube 609 is fixedly connected with a sealing plate 610. The four sealing plates 610 are arranged in a ring array with the axis of the functional tube 609 as the center. The surface of the sealing plate 610 is fixedly connected with the surface of the mounting ring 509.

[0054] Furthermore, in order to prevent dust from forming in the grain, a first sealing cover 611 and a second sealing cover 612 are fixedly connected to the inner wall of the small warehouse 1, respectively. The surface of the first sealing cover 611 is fixedly connected to the inner wall of the small warehouse 1, and the inner walls of the two first sealing covers 611 are slidably connected to the surfaces of the mounting ring 509 and the sealing plate 610, respectively.

[0055] The second sealing cover 612 is fixedly connected to the inner wall of the first sealing cover 611 and the surface of the loading / unloading workbench 3, respectively. The surface of the second sealing cover 612 is slidably connected to the lower surface of the mounting ring 509. Through the sealing plate 610, the first sealing cover 611 and the second sealing cover 612, the weighing box 510 and the interior of the small warehouse 1 between the two sealing plates 610 are sealed and dustproof.

[0056] By setting up a loading and unloading drive mechanism and a loading and unloading auxiliary mechanism, during use, the drive motor 504 drives the mounting ring 509 to rotate, which drives the four weighing boxes 510 to move. Through the cooperation of the sensing block 506 and the proximity sensor 507, the mounting ring 509 is controlled to drive the four weighing boxes 510 to move 90 degrees each time, so that the weighing boxes 510 enter the small warehouse 1 in sequence for loading, and then transport the loaded grains out of the small warehouse 1 in sequence for unloading, thereby solving the problem of slow weighing efficiency of existing grains.

[0057] Working Principle: During use, after the grains in the small warehouse 1 are shoveled or introduced into the weighing box 510 through the material pipe, the controller 4 controls the drive motor 504 to work. The output shaft of the drive motor 504 drives the worm gear 503 to rotate through the coupling. The worm gear 503 drives the worm wheel 501 to rotate. The worm wheel 501 drives the drive shaft 5 to rotate. The drive shaft 5 drives the connecting positioning plate 505 to rotate. The connecting positioning plate 505 drives the connecting pipe 508 and the mounting ring 509 to rotate. The mounting ring 509 drives the weighing box 510 to rotate 90 degrees, which in turn drives the sensing block 506 to rotate 90 degrees. The sensing block 506 approaches the proximity sensor 507, and the proximity sensor 507 sends an electrical signal back to the controller 4. The controller 4 then controls the drive motor 504 to stop working. After loading is completed, the controller... 4. Control the drive motor 504 to work again. The output shaft of the drive motor 504 drives the worm gear 503 to rotate through the coupling, which in turn drives the worm wheel 501 and the drive shaft 5 to rotate. This drives the connecting positioning plate 505, the connecting pipe 508, and the mounting ring 509 to rotate, causing the weighing box 510 to rotate 90 degrees again. The drive motor 504 drives the mounting ring 509 to rotate 90 degrees each time, and then the empty weighing box 510 is emptied. After that, the empty weighing box 510 moves back into the small warehouse 1. The staff inside the small warehouse 1 reload the grains and put them into the weighing box 510. Then, the drive motor 504 drives the mounting ring 509 to rotate, causing the weighing box 510 containing the grains to move to the outside of the small warehouse 1. The above actions are repeated.

[0058] Furthermore, during the rotation of the mounting ring 509 and the weighing box 510 by the drive motor 504, in order to prevent the grain particles from slipping out of the weighing box 510 due to the centrifugal force generated by the rotation, the support column 606 and the rotating ball 608 on the weighing box 510 slide from the positioning support protrusion 605 in the annular functional groove 604 to the inner bottom wall of the annular functional groove 604, so that the weighing box 510 is in an inclined state during the movement, preventing the grain particles from slipping out of the weighing box 510. After rotating ninety degrees, it moves to another positioning support protrusion 605, so that the weighing box 510 rotates to the outside and tilts downward.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
