[0040] Example 1

[0041] See Figures 1 to 7 The present invention provides an automatic sandbag filling device for flood control, including a frame 1. A feeding mechanism 2 for filling sandbags 4 into sandbags is provided on one side of the frame 1, and a column 1-1 is fixedly provided on the other side. A rotating frame 1-2 is rotatably provided on the column 1-1. The rotating frame 1-2 includes a circular plate-shaped bottom plate 1-3 and a top plate 1-4 arranged in parallel. A plurality of through-holes are arranged in an array on the top plate 1-4. A plurality of supporting mechanisms 3 for supporting the mouth of the sandbags 4 are arranged in an array on the top plate 1-4. Each supporting mechanism 3 corresponds to a bag hole.

[0042] And a drive unit 5 for driving the rotating frame 1-2 to rotate, the drive unit 5 being mounted on the frame 1.

[0043] The bag-supporting mechanism 3 includes an active bevel gear disk 3-1 rotatably mounted on the top plate 1-4, and several driven bevel gears 3-2 meshing on the active bevel gear disk 3-1. Each driven bevel gear 3-2 is arranged in a circumferential array on the outside of the bag-covering hole, and each driven bevel gear 3-2 is rotatably connected to the top plate 1-4 through a bracket.

[0044] Each driven bevel gear 3-2 has a threaded hole in the middle, and the bag support 3-3 is connected to the internal thread of the threaded hole.

[0045] Each bag support 3-3 includes a screw 3-31 threadedly connected to the driven bevel gear 3-2. An arc-shaped bag support plate 3-32 is fixedly installed at one end of the screw 3-31 facing the center of the bag hole. The center end of each bag support plate 3-32 is away from the screw 3-31.

[0046] An arc-shaped boss 3-33 is fixedly installed on the upper part of the support plate 3-32, and the boss 3-33 extends to the outer side of the outer wall of the support plate 3-32.

[0047] When the operator performs the bagging operation, the operator folds the mouth of the sandbag 4 outward and places the folded part of the mouth on the outside of the boss 3-33. The sealing rope ring 4-2 of the mouth of the sandbag 4 is located below the boss 3-33. When the bag is stretched, the active bevel gear 3-1 rotates, and the active bevel gear 3-1 drives multiple driven bevel gears 3-2 to rotate. Each driven bevel gear 3-2 controls the bag stretching plate 3-32 to move away from the center of the bag stretching hole. The multiple bag stretching plates 3-32 stretch the mouth of the sandbag 4. Under the action of the boss 3-33, even after the sandbag 4 is filled with sand, the sandbag 4 will not fall off the bag stretching plate 3-32.

[0048] After the sand is filled, the active bevel gear 3-1 rotates in the opposite direction. At this time, the active bevel gear 3-1 drives multiple driven bevel gears 3-2 to rotate in the opposite direction. Each driven bevel gear 3-2 drives the bag support plate 3-32 to move towards the side closer to the circular bag support hole. At this time, the bag support plate 3-32 cannot expand the opening of the sandbag 4. Under the weight of the sandbag 4, the sandbag 4 falls out of the bag support hole, thus realizing the automatic unloading of the sandbag 4.

[0049] A driven gear 3-4 is fixedly mounted on the outer side of the driving bevel gear disk 3-1;

[0050] A fixed frame 1-5 is fixedly installed on one side of the frame 1. An arc-shaped gear ring 1-6 is fixedly installed on the fixed frame 1-5. When the rotating frame 1-2 rotates to the gear ring 1-6, the gear ring 1-6 meshes with the corresponding driven gear 3-4.

[0051] The drive unit 5 of this device controls the rotating frame 1-2 to rotate counterclockwise. When the rotating frame 1-2 rotates to the gear ring 1-6, one of the bag-supporting mechanisms 3 on the rotating frame 1-2 corresponds to the gear ring 1-6. At this time, the gear ring 1-6 meshes with the driven gear 3-4 of the current bag-supporting mechanism 3. As the rotating frame 1-2 rotates, the driven gear 3-4 starts to rotate under the action of the gear ring 1-6, thereby driving the active bevel gear 3-1 to rotate, thereby expanding the opening of the sandbag 4, which makes it easier for the feeding mechanism 2 to fill the sandbag 4 with sand.

[0052] As the rotating frame 1-2 continues to rotate, the driven gear 3-4 of the current bag-supporting mechanism 3 separates from the gear ring 1-6. Since the driven bevel gear 3-2 and the bag support 3-3 are threadedly connected, the bag support 3-3 has a certain self-locking ability. When the driven bevel gear 3-2 is not rotated, the bag support 3-3 cannot move horizontally. At this time, when the feeding mechanism 2 fills the sandbag 4 with sand, the bag support mechanism 3 can always keep the opening of the sandbag 4 open.

[0053] An arc-shaped unlocking gear 1-7 is fixedly installed at the upper end of the column 1-1. When the rotating frame 1-2 rotates to the unlocking gear 1-7, the unlocking gear 1-7 meshes with the corresponding driven gear 3-4.

[0054] As the rotating frame 1-2 rotates, when the rotating frame 1-2 rotates to the unlocking gear 1-7, the bag-supporting mechanism 3 that has been filled corresponds to the unlocking gear 1-7. At this time, the unlocking gear 1-7 meshes with the driven gear 3-4 of the current bag-supporting mechanism 3. As the rotating frame 1-2 rotates, under the action of the unlocking gear 1-7, the driven gear 3-4 starts to rotate in the opposite direction, thereby driving the active bevel gear disk 3-1 to rotate. Each driven bevel gear 3-2 drives the bag-supporting plate 3-32 to move towards the side closer to the circular bag-supporting hole. At this time, the bag-supporting plate 3-32 cannot expand the bag opening of the sandbag 4. Under the weight of the sandbag 4, the sandbag 4 falls out of the bag-supporting hole, thus completing the automatic unloading of the sandbag 4.

[0055] The sandbag 4 includes a bag body 4-1, and a sealing rope ring 4-2 is provided at the opening of the bag body 4-1. The diameter of the sealing rope ring 4-2 is much larger than the diameter of the opening of the bag body 4-1. Several openings are arranged in an array on the opening. Since the bag body 4-1 is generally made of hemp, cloth, etc., it has a certain thickness. The openings can reduce the gaps at the opening when the bag is closed. When a certain amount of sand is filled into the sandbag 4, the opening of the sandbag 4 can be tightened by pulling the sealing rope ring 4-2, thereby achieving the closure of the opening of the sandbag 4.

[0056] A rope loop lock 4-3 is provided on the sealing rope loop 4-2, and the rope loop lock 4-3 is fixed to one of the openings of the bag.

[0057] The rope loop lock 4-3 includes two parallel clamping plates 4-4, which are fixed to the opening of the bag. A connecting plate 4-5 is fixed in the middle of the two clamping plates 4-4. A locking device 4-6 is rotatably installed on the clamping plates 4-4 at both ends of the connecting plate 4-5. The two locking devices 4-6 are arranged opposite to each other. The sealing rope loop 4-2 passes through the gap between the connecting plate 4-5 and the locking device 4-6.

[0058] Each locking device 4-6 includes a bushing 4-7 rotatably connected to the clamping plate 4-4. An arc-shaped locking platform 4-8 is fixedly provided on one side of the bushing 4-7. The outer wall of the locking platform 4-8 is spiral-shaped. One end of the locking platform 4-8 is fixedly connected to the outer wall of the bushing 4-7, and the other end extends to the outside of the bushing 4-7. The locking platforms 4-8 of the two locking devices 4-6 are arranged opposite each other.

[0059] Several triangular protrusions are arranged in an array on the outer wall of the locking platform 4-8. The protrusions can increase the friction between the locking platform 4-8 and the sealing rope ring 4-2, which can improve the locking ability of the locking platform 4-8 and prevent the bag opening from loosening during later use.

[0060] By pulling the sealing rope ring 4-2, the opening of the sandbag 4 can be tightened. The locking platform 4-8 locks the sealing rope ring 4-2 by reducing the distance between it and the connecting plate 4-5. The locking platform 4-8 can ensure that the sealing rope ring 4-2 can always tighten the opening of the sandbag 4, thereby achieving the closure of the opening of the sandbag 4, which is convenient for operators to handle, stack, etc. in the later stage.

[0061] A torsion spring is provided between each bushing 4-7 and the clamping plate 4-4, which ensures that the locking plate 4-8 is always in close contact with the sealing rope ring 4-2.

[0062] Several trays 1-8 are arranged in an array on the base plate 1-3. Each tray 1-8 is rotatably connected to the base plate 1-3. The end of the tray 1-8 closest to the center of the base plate 1-3 is rotatably connected to the base plate 1-3. When the tray 1-8 is subjected to the weight of the sandbag 4, the tray 1-8 forms an inclined surface, which facilitates the transfer of the sandbag 4 on the tray 1-8 to the outside of the frame 1. A spring is installed between the tray 1-8 and the base plate 1-3. The spring can keep the tray 1-8 in a horizontal state at all times. Each tray 1-8 is located below the bag-covering hole.

[0063] A connecting rod 1-9 is rotatably mounted on the plate 1-8. A hook 1-10 is rotatably mounted on the upper end of the connecting rod 1-9. The hook 1-10 is in the shape of a "J". One end of the hook 1-10 is rotatably connected to the top plate 1-4, and the middle part of the hook 1-10 is rotatably connected to the connecting rod 1-9.

[0064] When the operator places the sandbag 4 opening onto the bag-supporting mechanism 3, the operator hangs the sealing rope ring 4-2 of the sandbag 4 on the hook 1-10. After filling the sandbag 4 with a certain amount of sand, when the rotating frame 1-2 rotates to the unlocking gear 1-7, the bag-supporting mechanism 3, which has been filled, corresponds to the unlocking gear 1-7. At this time, the unlocking gear 1-7 meshes with the driven gear 3-4 of the current bag-supporting mechanism 3. As the rotating frame 1-2 rotates, under the action of the unlocking gear 1-7, the bag-supporting plate 3... -32 cannot expand the opening of sandbag 4. Under its own weight, sandbag 4 falls out of the opening. When sandbag 4 falls, the sealing rope ring 4-2 is thrown and hung on hook 1-10. By pulling the sealing rope ring 4-2 through hook 1-10, the opening of sandbag 4 can be tightened. Under the action of locking device 4-6, it can be ensured that the sealing rope ring 4-2 can always tighten the opening of sandbag 4, thereby achieving the sealing of the opening of sandbag 4, which is convenient for operators to handle, stack and so on.

[0065] When the sealing rope ring 4-2 fully tightens the opening of the sandbag 4, the lower end of the sandbag 4 contacts the upper surface of the pallet 1-8. After the pallet 1-8 is subjected to the weight of the sandbag 4, the pallet 1-8 forms an inclined plane. Under the action of the connecting rod 1-9, the pallet 1-8 drives the hook 1-10 to rotate, which facilitates the separation of the hook 1-10 from the sealing rope ring 4-2. Under the action of the pallet 1-8, the sandbag 4 is transferred to the outside of the frame 1.

[0066] The feeding mechanism 2 includes a hopper 2-1 fixedly mounted on the frame 1. The hopper 2-1 is funnel-shaped. An inclined feeding pipe 2-2 is fixedly mounted at the lower end of the hopper 2-1. An auger is rotatably mounted inside the feeding pipe 2-2.

[0067] A feeding motor 2-3 is fixedly installed at the upper end of the feeding pipe 2-2, and the motor shaft of the feeding motor 2-3 is fixed coaxially with the auger.

[0068] A discharge pipe 2-4 is fixedly installed at the upper part of the feeding pipe 2-2, and the feeding mechanism 2 fills sand into the sandbag 4 through the discharge pipe 2-4.

[0069] When using this device, sand can be poured into hopper 2-1 manually or by mechanical equipment such as a loader. Under the action of the auger, the sand in hopper 2-1 is transported to sandbag 4.

[0070] Furthermore, a weight sensor is installed on the bag-supporting mechanism 3. The weight sensor and the feeding motor 2-3 form an electrical control circuit. When the feeding mechanism 2 fills the sandbag 4 with sand, the sandbag 4 is considered full when the weight reaches the preset weight. Then the feeding motor 2-3 stops working. The feeding mechanism 2 feeds the sand intermittently, which can prevent excess sand from falling onto the rotating frame 1-2 and affecting the normal use of the rotating frame 1-2.

[0071] The drive unit 5 includes a base 5-1 fixedly mounted on the frame 1. A worm gear is rotatably mounted inside the base 5-1. One side of the worm gear meshes with a worm. The worm is rotatably connected to the base 5-1. A drive motor 5-2 is coaxially fixedly mounted on one end of the worm. The motor shaft of the drive motor 5-2 is coaxially fixed with the worm. The drive motor 5-2 is fixedly mounted on the base 5-1.

[0072] The worm gear is fixedly connected to the base plate 1-3.

[0073] Furthermore, an angle sensor is installed on the base 5-1, and the drive motor 5-2 controls the worm gear to rotate 90 degrees each time, which can ensure that after each rotation, the sandbag 4 is below the discharge pipe 2-4, making it convenient for the feeding mechanism 2 to fill the sandbag 4 with sand.

[0074] When using this invention, the device is placed next to a sand pile. Sand can be poured into the hopper 2-1 manually or by mechanical equipment such as a forklift. An operator performs the bagging operation on one side of the frame. The operator folds the mouth of the sandbag 4 outward and places the folded part of the mouth on the outside of the boss 3-33. The sealing rope ring 4-2 of the mouth of the sandbag 4 is located below the boss 3-33. When the rotating frame 1-2 rotates to the gear ring 1-6, one of the bag-supporting mechanisms 3 on the rotating frame 1-2 corresponds to the gear ring 1-6. At this time, the gear ring 1-6 meshes with the driven gear 3-4 of the current bag-supporting mechanism 3. The bag-supporting mechanism 3 expands the mouth of the sandbag 4, making it easier for the feeding mechanism 2 to fill the sandbag 4 with sand.

[0075] As the rotating frame 1-2 rotates, when the rotating frame 1-2 rotates to the unlocking gear 1-7, the bag-supporting mechanism 3 that has been filled corresponds to the unlocking gear 1-7. At this time, the unlocking gear 1-7 meshes with the driven gear 3-4 of the current bag-supporting mechanism 3. As the rotating frame 1-2 rotates, under the action of the unlocking gear 1-7, the bag-supporting plate 3-32 cannot expand the bag opening of the sandbag 4. Under the weight of the sandbag 4, the sandbag 4 falls out of the bag-supporting hole. By pulling the sealing rope ring 4-2, the bag opening of the sandbag 4 can be tightened, thereby achieving the closure of the bag opening of the sandbag 4. After the support plate 1-8 is subjected to the weight of the sandbag 4, the support plate 1-8 forms an inclined plane. Under the action of the connecting rod 1-9, the support plate 1-8 drives the hook 1-10 to rotate, which facilitates the separation of the hook 1-10 from the sealing rope ring 4-2. Under the action of the support plate 1-8, the sandbag 4 is transferred to the outside of the frame 1, thereby achieving the automatic unloading of the sandbag 4.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
