Description

Technical Field

[0001] This utility model relates to the field of flood control machinery and equipment technology, and more specifically, to a novel filling device for flood control sandbags. Background Technology

[0002] Sandbags are primarily used for temporary waterproofing projects and are essential for emergency temporary works and flood prevention. They offer advantages such as ease of transport, availability in various sizes, and rapid deployment. The common method of filling sandbags involves manual filling directly next to sand piles. While this doesn't require large equipment, it wastes significant manpower and is difficult to control in terms of time, making it unsuitable for emergency flood control. Commonly used sandbag filling machines typically require conveyors to transport sand into the sandbags for filling. This method is space-constrained, requires large machinery, and is cumbersome.

[0003] To address these issues, researchers have proposed several solutions. For example, patent CN113120265B discloses a sandbag filling device, which features one-person operation, automatic sand extraction, and heat-sealing. However, horizontal bag support is difficult to achieve, and the heat-sealing process renders the sandbags disposable, wasting resources and costs. Furthermore, it is difficult to use in space-constrained locations and is inconvenient to transport. Patent CN117246616A discloses an automatic flood control sandbag filling device, which features one-person operation and a small frame. However, the bag insertion and removal operations are cumbersome and fail to achieve the goal of saving time. Utility Model Content

[0006] Furthermore, the upper end of the bottom support includes a plane, an arc-shaped surface, and an inclined surface connected in sequence. The plane is close to the opening of the main frame. The upper end of the arc-shaped surface is connected to the plane. The lower end of the arc-shaped surface is connected to the lower end of the inclined surface. The upper end of the inclined surface is flush with the plane. The slide rail is disposed on the plane and the arc-shaped surface. A pulley is disposed at the lower end of the bag box near the opening of the main frame.

[0007] Furthermore, a ball bearing is provided on the upper part of the side of the bag box facing away from the opening of the main frame, and a support rod parallel to the opening of the main frame is provided inside the main frame. The bag box is hinged to the support rod through the ball bearing, and the telescopic pull rod is located below the ball bearing.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-8 As shown, the filling device for the novel flood control sandbag in this embodiment includes a sand filling mechanism and a sand conveying mechanism.

[0030] The sand-filling mechanism includes a main frame 1, a bottom support 2, a sandbag box 3, and a telescopic rod 4. The main frame 1 is a square columnar frame structure with an opening on one vertical side. The bottom support 2 is fixed to the bottom inner side of the main frame 1 to support the sandbag box 3. A slide rail 5 is provided at the upper end of the bottom support 2, and the sandbag box 3 is slidably mounted on the slide rail 5. The upper end of the sandbag box 3 and the side facing the opening of the main frame 1 are open, which facilitates the placement of sandbags into the sandbag box 3 and the sandbag openings being fitted over the upper opening of the sandbag box 3. The side of the sandbag box 3 facing away from the opening of the main frame 1 is connected to the main frame 1 via the telescopic rod 4.

[0031] Specifically, in this embodiment, the upper end of the bottom support 2 includes a plane, an arc-shaped surface, and an inclined surface connected in sequence. The plane is close to the opening of the main frame 1. The upper end of the arc-shaped surface is connected to the plane, and the lower end of the arc-shaped surface is connected to the lower end of the inclined surface. The upper end of the inclined surface is flush with the plane. The slide rail 5 is disposed on the plane and the arc-shaped surface. A pulley 19 is disposed at the lower end of the bag box 3 near the opening of the main frame 1. A ball bearing 9 is disposed on the upper part of the side of the bag box 3 facing away from the opening of the main frame 1. A support rod 10 parallel to the opening of the main frame 1 is disposed inside the main frame 1. The bag box 3 is hinged to the support rod 10 through the ball bearing 9. A telescopic pull rod 4 is disposed below the ball bearing 9. When the telescopic rod 4 is extended, the bag box 3 is upright, and the pulley 19 is located on the plane at the upper end of the bottom support 2. When the telescopic rod 4 is retracted, the lower part of the bag box 3 is pulled by the telescopic rod 4, which causes the bag box 3 to rotate and tilt around the ball bearing 9. The pulley 19 slides to the bottom of the arc-shaped surface at the upper end of the bottom support 2. The inclined surface at the upper end of the bottom support 2 blocks the pulley 19 to prevent the pulley 19 from falling off the bottom support 2. When the telescopic rod 4 is extended again, the bag box 3 returns to the upright position. The purpose of repeating this process is to facilitate emptying the filled sandbags.

[0032] In this embodiment, the telescopic rod 4 includes a first connecting rod 401, a second connecting rod 402, and an electric spring 403. The first connecting rod 401 and the second connecting rod 402 are rotatably connected, and the ends of the first connecting rod 401 and the second connecting rod 402 that are far apart from each other are respectively hinged to the main frame 1 and the bag box 3. The two ends of the electric spring 403 are respectively connected to the first connecting rod 401 and the second connecting rod 402. The working principle of the energized spring 403 is based on the action of Ampere force. When the energized spring 403 is energized, each coil of the spring can be regarded as a circular current. The current-carrying conductor in the magnetic field will be subjected to the action of Ampere force. For two adjacent coils of spring, since the current direction is the same, according to the principle that currents in the same direction attract each other, an attraction is generated between the coils of spring, causing the energized spring 403 to contract, thereby driving the first connecting rod 401 and the second connecting rod 402 to contract. When the energized spring 403 is de-energized, the first connecting rod 401 and the second connecting rod 402 unfold, thereby causing the telescopic pull rod 4 to pull or push the bag box 3.

[0033] In this embodiment, a weight sensing plate is provided at the bottom of the bag-holding box 3. A power module 11 and a control module 12 are installed inside the main frame 1. The power module 11 is connected to the control module 12, the weight sensing plate, the energized spring 403, and the motor 8. The control module 12 is also connected to the weight sensing plate, the energized spring 403, and the motor 8. The weight sensing plate is located on the upper surface of the bottom of the bag-holding box 3 and is used to sense the real-time weight of the sandbags.

[0034] Preferably, an hourglass 13 is provided at the top inner side of the main frame 1, and a sand filling port 14 is provided at the bottom of the hourglass 13. A switchable partition 15 and a drive mechanism (not shown in the figure) for driving the partition 15 to open and close are provided at the lower end of the sand filling port 14. The drive mechanism is connected to the power module 11 and the control module 12. Specifically, the drive mechanism can be a motor 8 drive assembly or an electric telescopic rod drive assembly. Its principle is the same as that of the electric folding door in the prior art, and will not be described in detail here.

[0035] The power module 11 supplies power to the control module 12, the weight sensor plate, the energized spring 403, the motor 8, and the drive mechanism. The control module 12 consists of a display screen, an input keyboard, a start button, a stop button, and a tilt button. It is used to control the overall power supply switch of the power module 11 to other electrical components. It can also set the weight when feeding and tilting are stopped. It should be noted that if the preset weight is not modified, it will be consistent with the previous preset value.

[0036] In this embodiment, the upper end of the bag box 3 and the two outer side walls adjacent to the outer side wall of the ball bearing 9 are provided with side ears 16. Two side ears 16 are arranged vertically on each of the two outer side walls for hanging the pull ropes of sandbags of different sizes, so that sand can enter the bag from the lower end of the sand funnel.

[0037] In this embodiment, a support frame 17 is provided on the upper end of the main frame 1. The support frame 17 has an n-shaped structure and is used to support the motor 8. It can also be used as a lifting lug to facilitate the hoisting of the main frame 1. The feeding port 6 is inclined, and a feeding support frame 18 is provided below the feeding port 6. The bottoms of the main frame 1 and the feeding support frame 18 are located on the same plane. Under normal circumstances, the main frame 1 and the feeding support frame 18 can be placed on the ground.

[0038] The working principle of the filling device for the novel flood control sandbags in this embodiment is as follows:

[0039] First, use a crane to hook the support frame 17 and place the device in a suitable position next to the sand pile. When the power module 11 is turned on, press the start button to supply power to the control module 12, weight sensor plate, energized spring 403, motor 8, and drive mechanism. Input the final weight of the sandbag into the control module 12, place the sandbag in the bag box 3, and hang the pull ropes on both sides of the sandbag on the side ears 16 to open the bag mouth. Use a shovel to shovel sand into the feeding port 6, and the motor 8 drives the rotating auger to lift the sand to the top of the transport pipe 7, which then flows into the sandbag through the sand hourglass. When the weight of the sandbag reaches the preset value of the control module 12, that is, when the weight sensor plate senses the preset weight, the drive mechanism drives the partition 15 to close, and the partition 15 at the lower end of the sand hourglass 13 blocks the discharge port, stopping the feeding. After manually sealing the bag opening, place the trolley in front of the bag-holding box 3. Press the tilt button on the control module 12 to pull the bag-holding box 3 by the telescopic lever 4, and the sandbags will be poured into the trolley. Workers will then transport it to the flood control site. Press the tilt button again to reset the bag-holding box 3. Repeat this process. Once the required number of sandbags have been filled, press the stop button to deactivate the power supply.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
