Description

Technical Field

[0001] This utility model relates to the technical field of shallow circular warehouse ventilation trough cleaning equipment, and in particular to an intelligent cleaning trolley for grain warehouse ventilation troughs. Background Technology

[0002] In grain storage, shallow round silos are a widely used storage facility, and their internal ventilation system plays a crucial role in maintaining grain quality. Good ventilation effectively controls temperature and humidity, preventing grain from molding and spoiling due to dampness, while also reducing the risk of insect infestation. Ventilation troughs, a key component of the shallow round silo's ventilation system, are typically located underground or near the ground, maintaining a suitable storage environment by promoting air circulation. To ensure the efficient operation of the ventilation system, after the grain is removed from the silo, dust and other residues must be cleaned from the ventilation troughs to prevent a decrease in ventilation effectiveness and to avoid the breeding of insect eggs, thereby ensuring the quality of subsequently stored grain.

[0003] Ventilation trenches are typically designed with metal gratings laid on top. These gratings not only support the grain but also allow for free airflow while protecting the ventilation system below from large particles. The relatively small apertures in the metal gratings, while ensuring ventilation, also present challenges for cleaning. Traditional cleaning methods often rely on manual labor. Workers must manually move the heavy metal gratings, use tools to clean dust and debris from the trench, and then re-lay the gratings. This process is not only time-consuming and labor-intensive but also poses certain safety hazards, such as the risk of workers being crushed by heavy objects or accidents occurring while working in confined spaces.

[0004] However, traditional manual cleaning methods face numerous problems. First, due to the weight and quantity of the metal grilles, manually moving and laying them is extremely labor-intensive and inefficient. Second, the suction hoses of commonly used cleaning equipment such as vacuum cleaners cannot penetrate the small holes in the grilles to thoroughly clean the trenches, resulting in incomplete cleaning and affecting ventilation. Furthermore, manual cleaning involves personnel entering confined spaces, increasing safety risks. Therefore, developing an automated and intelligent cleaning system is particularly urgent to improve the efficiency and safety of cleaning work, reduce labor intensity, and ensure that the ventilated trenches are always kept in optimal condition. Utility Model Content

[0005] To address the problems existing in cleaning the ventilation troughs of shallow circular granaries, this utility model provides an intelligent cleaning trolley for granary ventilation troughs. The trolley uses a lifting mechanism and an electromagnet to hoist open the metal grid cover of the ventilation trough, and then uses a dust collection device to clean the inside of the ventilation trough, thereby reducing the workload of workers cleaning the ventilation trough and increasing the cleaning speed.

[0006] The solution adopted by this utility model to solve its technical problem is: a smart cleaning vehicle for a grain warehouse ventilation trough, including a vehicle body, a power and control box and a vacuum cleaner main unit are installed on the vehicle body, a front connecting plate is installed at the front of the vehicle body, a lifting mechanism is vertically installed on the front connecting plate, a right-angled plate is installed on the lifting mechanism, the vertical plate of the right-angled plate is fixed to the lifting mechanism, an electromagnet is fixed on the lower side of the horizontal plate of the right-angled plate, and the vacuum cleaner main unit is connected to a flexible suction pipe that can extend into the ventilation trough.

[0007] Furthermore, a flexible hose perforation is provided in the middle of the horizontal plate of the right-angle carrier plate, through which a flexible vacuum tube passes from above and extends into the ventilation trench.

[0008] Furthermore, the lifting mechanism includes guide rails and a lead screw. A set of parallel guide rails is vertically fixed on the head connecting plate. A lead screw is installed between the guide rails through bearing seats. The lead screw is parallel to the guide rails. A slider is fitted on the guide rails, and a sliding sleeve is fitted on the lead screw. The vertical plate of the right-angle carrier plate is fixed on the sliders of the two guide rails, keeping the horizontal plate of the right-angle carrier plate horizontal. The sliding sleeve on the lead screw is also fixed to the vertical plate of the right-angle carrier plate. A drive motor is installed at the end of the lead screw. The drive motor drives the lead screw to rotate, thereby driving the right-angle carrier plate to move up and down along the guide rails.

[0009] Furthermore, four electromagnets are fixed to the lower side of the horizontal plate of the right-angled carrier plate.

[0010] Furthermore, four mounting holes are evenly spaced on the horizontal plate of the right-angle carrier plate. The mounting holes are located at the corners of the horizontal plate. A bushing is fitted into the mounting hole, and a lifting rod is fitted into the bushing. A stop is provided at the upper end of the lifting rod, which is located above the horizontal plate. An electromagnet is installed at the lower end of the lifting rod, and an elastic element is fitted on the lifting rod, which is located between the horizontal plate and the electromagnet.

[0011] Furthermore, it also includes a toolbox, which is installed on the underside of the vehicle body, with the toolbox lid located on the side of the toolbox.

[0012] The beneficial effects of this utility model are as follows: This utility model provides an intelligent sweeping trolley for cleaning the ventilation troughs of grain warehouses. By using a lifting mechanism and electromagnets to move the trough covers, it can significantly reduce the time and labor intensity required for manual cleaning and improve the efficiency of the cleaning work. Mechanized cover handling reduces reliance on manpower and can greatly reduce labor costs.

[0013] The use of electromagnetic handling and dust collection equipment reduces manual operation, avoids the risk of workers being hit by mechanical collisions and working in confined spaces, and improves operational safety; the intelligent sweeping cart adopts battery power and an effective dust removal design to reduce environmental pollution, which is in line with the current concept of green and sustainable development.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below.

[0020] Example 1: To reduce the labor intensity of manual cleaning of the ventilation troughs in grain silos, and to better achieve safe and efficient maintenance of the grain silos after grain is removed from storage, this utility model provides a method... Figure 1 and Figure 2 The intelligent sweeping vehicle shown is a grain silo ventilation trough cleaning vehicle. This vehicle includes a chassis 1, which is powered by a battery and features a rear-wheel drive design, ensuring both power performance and maneuverability. Battery power also makes the equipment more environmentally friendly. Furthermore, the vehicle utilizes existing intelligent control technology, combined with visual recognition technology and LiDAR scanning, enabling autonomous driving and improving operational accuracy. It also allows for remote operation by staff, significantly enhancing operational efficiency and safety.

[0021] A power and control box 2 is installed on the vehicle body 1. The power system and intelligent control system of the vehicle are installed in the power and control box 2. The power system uses a battery to drive a motor with a reducer. The motor drives the rear wheel of the vehicle body 1 to rotate through a sprocket and a chain, thereby driving the intelligent sweeping vehicle to move.

[0022] A vacuum cleaner main unit 3 is also installed on the vehicle body 1. The vacuum cleaner main unit 3 is connected to a flexible suction pipe 4, which can extend into the ventilation groove 10 to clean the groove. When cleaning accumulated dust, the flexible suction pipe 4 can suck the dust into the dust box of the vacuum cleaner main unit 3, effectively preventing the dust from being re-entrained and ensuring that the cleaning work is clean and thorough.

[0023] A front connecting plate 5 is installed at the front of the vehicle body 1. A lifting mechanism 6 is vertically mounted on the front connecting plate 5. A right-angle carrier plate 7 is mounted on the lifting mechanism 6. The vertical section of the right-angle carrier plate 7 is fixed to the lifting mechanism 6. An electromagnet 8 is fixed to the underside of the horizontal section of the right-angle carrier plate 7. Through the attraction between the lifting mechanism 6 and the high-strength electromagnet 8, the trolley can easily lift and move the metal cover of the grain warehouse ventilation trough, avoiding the trouble of manual handling of the cover by workers, reducing the workload and intensity of cleaning work, and significantly improving the cleaning speed of the grain warehouse ventilation trough.

[0024] To avoid interference between the flexible suction pipe 4 and the lifting mechanism 6, such as Figure 2 As shown, a flexible hose perforation 701 is provided in the middle of the horizontal plate of the right-angled carrier plate 7. The flexible suction pipe 4 passes through the flexible hose perforation 701 from the top of the horizontal plate and extends into the ventilation groove 10, so as to avoid the flexible suction pipe 4 affecting the movement of the vehicle body 1 during the movement of the vehicle body 1.

[0025] like Figure 3 As shown, the lifting mechanism 6 includes guide rails 601 and a lead screw 606. A set of parallel guide rails 601 are vertically fixed on the head connecting plate 5. The lead screw 606 is installed between the guide rails 601 through bearing seats 604. The lead screw 606 is parallel to the guide rails 601. A slider 602 is fitted on the guide rails 601. A sliding sleeve 605 is fitted on the lead screw 606. The vertical plate of the right-angle carrier plate 7 is fixed on the slider 602 of the two guide rails 601, keeping the horizontal plate of the right-angle carrier plate 7 horizontal. The sliding sleeve 605 on the lead screw 606 is also fixed to the vertical plate of the right-angle carrier plate 7. A drive motor 603 is installed at the end of the lead screw 606. The drive motor 603 drives the lead screw 606 to rotate, thereby driving the right-angle carrier plate 7 to move up and down along the guide rails 601.

[0026] The lifting mechanism 6, through the longitudinal guide rail 601 and the lead screw 606 in conjunction with the electromagnet 8, can easily lift and move the ventilation trough 10 cover plate 9, simplifying the traditional complex mechanical structure, reducing the difficulty of operation, and improving the reliability of the sweeping trolley.

[0027] like Figure 2 As shown, the intelligent cleaning vehicle is equipped with four electromagnets 8, all of the same model and power. Four mounting holes are evenly spaced on the horizontal plate of the right-angle carrier plate 7, located at the corners of the plate. Figure 4As shown, a bushing 801 is fitted into the mounting hole, and a lifting rod 802 is fitted into the bushing 801. A stop is provided at the upper end of the lifting rod 802, and the stop is located above the horizontal plate. An electromagnet 8 is installed at the lower end of the lifting rod 802. An elastic element 803 is fitted on the lifting rod 802, and the elastic element 803 is located between the horizontal plate and the electromagnet 8.

[0028] During the process of electromagnet 8 attracting and lifting the grain silo ventilation trough cover 9, the elastic element 803 can deform, thereby forming a buffer, reducing the impact generated during the attraction of the cover, and improving the safety and reliability of the sweeping trolley.

[0029] The intelligent sweeping trolley provided by this utility model mainly consists of a power unit, an intelligent control unit, a cover lifting unit, and a dust removal unit. The power unit uses a battery-powered drive motor 603 to drive the rear wheels of the vehicle body 1, forming a rear-wheel drive structure that ensures the trolley's power performance and flexibility. The intelligent unit employs visual recognition technology and lidar scanning, processed by a controller, enabling automatic driving of the sweeping trolley. It can also be remotely controlled by staff, improving the efficiency and safety of sweeping operations. The cover lifting unit uses a lifting mechanism 6, which uses four high-strength electromagnets 8 to attract and move the steel cover plate of the grain silo ventilation trough 9. After moving the cover plate 9, the dust collector can clean the accumulated dust in the ventilation trough 10 and suck it into the ash box.

[0030] Further as Figure 1 As shown, a toolbox 11 is also installed on the lower side of the vehicle body 1. The lid of the toolbox 11 is located on the side of the toolbox 11. The toolbox 11 can carry cleaning or maintenance tools, which facilitates cleaning and quick repair and maintenance of the cleaning cart. The side opening mechanism makes it easy for staff to access the required tools.

[0031] This invention reduces the labor intensity of manual cleaning of grain warehouse ventilation troughs, while also enabling safer and more efficient maintenance of the grain warehouse after grain is removed. By combining intelligent unmanned driving technology with daily grain warehouse management, it provides a new component for intelligent grain warehouse management, significantly improving efficiency and accurately completing target tasks.

[0032] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
