[0046] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.
[0047] Please refer to Figures 1-3 This invention provides an embodiment of a portable road crack sealing device, comprising a storage bin 100, a moving mechanism 200, and a control mechanism 300; the storage bin 100 is used to store crack sealing material, the moving mechanism 200 is located at the lower part of the storage bin 100 to support the storage bin 100 and facilitate its transfer; the control mechanism 300 serves as the operating part of the crack sealing device and can be held by hand or used to control the opening or closing of the material outlet of the storage bin 100.
[0048] The storage silo 100 includes a material cylinder 110 and a feed hopper 120. The inner cavity of the material cylinder 110 serves as the main storage chamber, with openings at both ends. The upper end is a filling port, and the lower end connects to the feed hopper 120. Preferably, the material cylinder 110 is cylindrical with a circular cross-section. The feed hopper 120 is similar to a cone, with its upper end being the larger end, which connects to and communicates with the material cylinder 110; its lower end is the smaller end, and the discharge port is located at the smaller end of the feed hopper 120. The material cylinder 110 and the feed hopper 120 can be welded from steel plates, resulting in a simple structure, easy processing and manufacturing, and low cost.
[0049] The moving mechanism 200 includes a connecting bracket 210, an auxiliary bracket 220, and moving wheels 230. There are two connecting brackets 210, located on opposite sides of the storage silo 100, symmetrically arranged relative to the silo 100. The upper end of each connecting bracket 210 is fixedly connected to the storage silo 100, and the moving wheels 230 are installed at the lower end of each connecting bracket 210. The two ends of the auxiliary bracket 220 are fixedly connected to the two connecting brackets 210, strengthening the structural strength of the connecting brackets 210. The connecting brackets 210 and the auxiliary bracket 220 can be manufactured from materials such as metal plates or metal pipes.
[0050] Furthermore, the movable wheel 230 is preferably a swivel wheel, which facilitates adjustment of the crack filling operation position and can adapt to curved and tortuous cracks.
[0051] The lower end of the feed hopper 120 extends away from the auxiliary support 220, forming an inclined guiding and material guiding surface at the bottom of the feed hopper 120, which can prevent the grouting material from accumulating inside.
[0052] Two moving wheels 230 and hopper 120 form a three-point support on the underside of cylinder 110, stably supporting storage bin 100.
[0053] The control mechanism 300 includes a lifting rod 310, a spring 320, a handle 330, and a bracket 340. The bracket 340 is the mounting carrier for the lifting rod 310, the spring 320, and the handle 330, and includes two vertical rods 344, an operating rod 341, a limiting rod 342, and a guide rod 345.
[0054] The operating lever 341 is horizontally positioned, with one end extending above the discharge port of the feed hopper 120 and the other end extending above the two moving wheels 230, preferably directly above the midpoint of the line connecting the two moving wheels 230. A vertical rod 344 is vertically positioned, with its upper end fixedly connected to the end of the operating lever 341 and its lower end fixedly connected to the material cylinder 110; the two vertical rods 344 are respectively fixedly connected to the two ends of the operating lever 341. A guide rod 345 is parallel to the operating lever 341 and is located below the operating lever 341; both ends of the guide rod 345 are fixed to the two vertical rods 344. The guide rod 345 has a guide hole 346 that extends vertically through the guide rod 345. A limiting rod 342 extends vertically, with both ends connected to the operating lever 341 and the guide rod 345, and the limiting rod 342 has a vertically extending limiting hole 343.
[0055] The vertical rod 344, operating rod 341, limiting rod 342, and guide rod 345 are interconnected to form a frame structure, making the bracket 340 simple and stable. The vertical rod 344, operating rod 341, limiting rod 342, and guide rod 345 can be made of round tubing, welded together to form the bracket 340, resulting in a lightweight yet high-strength structure.
[0056] One end of the handle 330 is a connecting end, and the other end is an operating end. The connecting end of the handle 330 is hinged to one of the vertical rods 344. The handle 330 passes through the limiting hole 343 and extends to the other side of the limiting rod 342. A wristband 347 is provided on the operating end of the handle 330. Preferably, the connecting end of the handle 330 is hinged to the vertical rod 344 located above the discharge port, and the operating end extends above the moving wheel 230, making it convenient for the operator to drag the equipment and control the handle 330 from the side of the moving wheel 230.
[0057] The lower end of the lifting rod 310 extends into the feed hopper 120 and is connected to a baffle 350. The baffle 350 is rotatably connected to the lifting rod 310 and is used to block or open the discharge port of the feed hopper 120. The upper end of the lifting rod 310 passes through the guide hole 346 and is hinged to the handle 330. The lifting rod 310 is slidably disposed in the guide hole 346. When the handle 330 is rotated, it drives the lifting rod 310 to rise and fall. Since the lifting rod 310 generates a horizontal displacement during the rising and falling process, the guide hole 346 is an elongated hole that extends along the length of the handle 330.
[0058] The two ends of the spring 320 are connected to the guide rod 345 and the handle 330 respectively. A downward force is applied to the handle 330 to keep the baffle 350 blocking the outlet. Alternatively, the spring 320 is fitted on the outside of the lifting rod 310, and the two ends of the spring 310 abut against the lifting rod 310 and the guide rod 345 respectively. A downward force can also be applied to the handle 330 to ensure that the outlet is blocked when no grouting operation is performed.
[0059] During use, ensure that the baffle 350 blocks the outlet of the feed hopper 120, load the grouting material into the storage bin 100, and drag the equipment via the support 340 for construction. During construction, lift the operating end of the handle 330 via the wristband 347. The lifting rod 310 and the baffle 350 connected to the handle 330 are pulled up, the outlet is opened, and the grouting material flows out from the outlet, dragging the equipment along the crack to complete the grouting construction. During the lifting of the handle 330, the spring 320 undergoes elastic deformation. After the upward pull on the wristband 347 is removed, the operating end of the handle 330 rotates downward under the action of the spring 320, and the lifting rod 310 and the baffle 350 return to their original position, blocking the outlet.
[0060] Furthermore, such as Figure 4 As shown, it also includes an auxiliary nozzle 360, which is a funnel-shaped nozzle that matches the inner cavity of the feed hopper 120. It is positioned at the discharge port of the feed hopper 120, with its upper end inside the feed hopper 120 and its lower end extending out of the discharge port. Since both the inner cavity of the feed hopper 120 and the auxiliary nozzle 360 are funnel-shaped, they are self-positioning, eliminating the need for additional positioning structures on the feed hopper 120, thus simplifying assembly. Simultaneously, the upper end of the auxiliary nozzle 360 forms a sealing surface that fits tightly against the baffle 350, preventing gaps between the flat baffle 350 and the inclined inner wall of the feed hopper 120. Furthermore, the cross-sectional size of the discharge port can be changed by replacing the auxiliary nozzle 360, allowing selection of a suitable discharge channel cross-sectional size based on the crack width.
[0061] Of course, depending on the actual application needs, the discharge port of the feed hopper 120 can be set to a universal size to match the conventional application environment, and the auxiliary nozzle 360 can be selected as needed.
[0062] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
