Description
Technical Field
[0001] This utility model relates to the field of sand and gravel transportation technology, specifically to a sand and gravel transportation device that prevents falling. Background Technology
[0002] A sand and gravel conveyor belt is a device used to transport sand, gravel, and other granular materials. It typically consists of a rubber belt and a supporting structure. Sand and gravel conveyor belts are used in mining, construction, and engineering fields to transport sand and gravel from one location to another.
[0003] In the process of developing this utility model, the inventors discovered the following unresolved problems in the existing technology: Most existing sand and gravel transport vehicles have hinged doors on three sides of the vehicle's bottom plate, which are then mutually restrained to form a cargo bed. After unloading, the door restraints are removed and the doors are opened, and tools such as shovels are used to push the sand and gravel off the bottom plate. However, the hinged doors in this method have large gaps, causing sand and gravel to fall and be wasted during transportation. Some methods use woven bags to be laid at the hinge joints, but due to bumpy transportation or improper laying, varying degrees of material loss often occur. Furthermore, the residual material on the bottom plate needs to be pushed off manually, which is time-consuming and labor-intensive. Therefore, we propose a sand and gravel transport device that prevents material from falling off. Utility Model Content
[0004] The purpose of this utility model is to provide a sand and gravel transportation device that prevents falling, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand and gravel transport device to prevent falling, comprising a truck bed, wherein gantry plates are fixedly installed on both sides of the bottom of the truck bed, and a bottom plate is placed at the bottom of the truck bed;
[0006] The bottom of the truck bed is integrally formed as an opening, with the bottom plate located below the opening and the gantry plate located outside the bottom plate;
[0007] A sealing gasket is fixedly installed on the upper surface of the bottom plate, and the sealing gasket is deformed under pressure and filled between the bottom plate and the truck bed. A handle is fixedly installed at one end of the bottom plate.
[0008] A stop block is fixedly installed on the side of the truck bed near the bottom plate, and the stop block is in contact with the end of the bottom plate;
[0009] A bracket is fixedly installed on the front side of the gantry panel. A rod is movably inserted through the side of the truck bed near the bracket. An iron block is fixedly installed at the end of the rod. A tension spring is sleeved on the outside of the rod, and the two ends of the tension spring are fixedly connected to the iron block and the truck bed, respectively. The inner end of the rod is locked in a slot preset on one side of the base plate.
[0010] A box is fixedly installed on one side of the outer wall of the truck bed. It can be used in conjunction with components such as a bottom plate, sealing gasket, and gantry plate. During the use of the sand and gravel transportation device, whenever the transport trolley is pushed to the unloading location, the bottom plate can be removed by adjusting the outward insertion rod. Then, the handle is held and the bottom plate is pulled. As the bottom plate is gradually removed, the sand and gravel material in the truck bed falls out and is discharged. Then, the truck body is pulled to discharge the remaining sand and gravel. Then, the bottom plate is reinstalled by reversing the operation. Compared with the existing transport trolley, it can avoid the waste caused by sand and gravel falling through the gaps. At the same time, this unloading method is more efficient and labor-saving.

The battery is electrically connected to the electronic controller through wires, and the electronic controller is electrically connected to the electromagnet through wires. The electromagnet and spring can be used together to apply force to the insertion rod, so that the insertion rod is stably inserted into the slot. If it is necessary to move the insertion rod outward, the electromagnet can be turned on, the electromagnet generates a magnetic field and attracts the iron block, so that the insertion rod moves outward and is temporarily limited. Conversely, when the electromagnet is turned off, the spring can return the insertion rod to its original position. This structural design has a convenient insertion rod adjustment function and the use effect is quite ideal.
[0012] As an optional solution to the technical solution of this application, a protective net is fixedly installed at the opening of the box, and an operating port is opened on the outside of the box near the electronic controller. The protective net can block external dust, and the electronic controller can be adjusted through the operating port, which meets the usage requirements.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Please see Figure 1-3This utility model provides a technical solution: a sand and gravel transport device to prevent falling, including a truck bed 1. An indicator sign 11 is fixedly installed on the top of the front wall of the truck bed 1, and the indicator sign 11 is fixed by welding. The indicator sign 11 can introduce the usage method and inform about safety precautions, facilitating understanding and safe use. Gantry plates 2 are fixedly installed on both sides of the bottom of the truck bed 1. A base plate 5 is placed at the bottom of the truck bed 1. Support rods 13 are fixedly installed at the four corners of the bottom of the truck bed 1, and the bottom ends of the support rods 13 are connected to casters via wheel frames. A handle 12 is fixedly installed on the upper side of the truck bed 1 near the box body 3. The truck bed 1 can be moved quickly and easily by gripping the handle 12 and pushing the casters of the support rods 13. The bottom of the truck bed 1 is integrally formed as an opening, and the bottom... Plate 5 is located below the opening, and gantry plate 2 is located outside the base plate 5; a sealing gasket 51 is fixedly installed on the upper surface of the base plate 5, and the sealing gasket 51 is deformed under pressure and filled between the base plate 5 and the truck bed 1. A handle 52 is fixedly installed at one end of the base plate 5; a stop block 14 is fixedly installed on the side of the truck bed 1 near the base plate 5, and the stop block 14 is in contact with the end of the base plate 5; a bracket 4 is fixedly installed on the front side of a set of gantry plates 2, and a plug rod 44 is movably inserted through the side of the truck bed 1 near the bracket 4. An iron block 43 is fixedly installed at the end of the plug rod 44, and a tension spring 41 is sleeved on the outside of the plug rod 44. The two ends of the tension spring 41 are fixedly connected to the iron block 43 and the truck bed 1 respectively. The inner end of the plug rod 44 is locked in a slot 53 preset on one side of the base plate 5; a box 3 is fixedly installed on the outer wall of one side of the truck bed 1.
[0025] In this technical solution, components such as the base plate 5, sealing gasket 51, and gantry plate 2 can be used together. During the use of the sand and gravel transportation device, whenever the transport trolley is pushed to the unloading location, the limiting position of the base plate 5 can be removed by adjusting the outward insertion rod 44. Then, the gripping rod 52 is held and the base plate 5 is pulled. As the base plate 5 is gradually removed, the sand and gravel material in the truck bed 1 falls and is discharged. Then, the truck body is pulled to discharge the remaining sand and gravel. Then, the operation is reversed to reinstall the base plate 5. Compared with the existing transport trolley, it can avoid the waste caused by sand and gravel falling through the gaps. At the same time, this unloading method is more efficient and labor-saving.
[0026] In some technical solutions, an electromagnet 42 is fixedly installed inside the bracket 4, and a battery 31 and an electronic controller 32 are fixedly installed inside the box 3. A protective net is fixedly installed at the opening of the box 3, and an operation port 33 is opened on the outside of the box 3 near the electronic controller 32. The protective net can block external dust, and the electronic controller can be adjusted through the operation port 33 to meet the usage requirements. The battery 31 is electrically connected to the electronic controller 32 through wires, and the electronic controller 32 is electrically connected to the electromagnet 42 through wires.
[0027] In this technical solution, components such as electromagnet 42 and tension spring 41 can be used together. The tension spring 41 can apply force to the insertion rod 44, so that the insertion rod 44 is stably inserted into the slot 53. If it is necessary to move the insertion rod 44 outward, the electromagnet 42 can be turned on. The electromagnet 42 generates a magnetic field and attracts the iron block 43, so that the insertion rod 44 moves outward and is temporarily limited. Conversely, when the electromagnet 42 is turned off, the tension spring 41 can make the insertion rod 44 return to its original position. This structural design has a convenient insertion rod 44 adjustment function and the use effect is quite ideal.
[0028] Working principle: It should be noted that this utility model is a sand and gravel transportation device that prevents falling. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or conventional test methods.
[0029] When using a sand and gravel transport device that prevents falling, push the sand and gravel transport device to the loading area, then add sand and gravel through the open top of the truck bed 1, then hold the handle 12 and push the casters to transport the sand and gravel to various work stations for short distances.
[0030] By incorporating a base plate 5, sealing gasket 51, and gantry plate 2, during the operation of the sand and gravel transport device, whenever the transport trolley is pushed to the unloading location, the limiting position of the base plate 5 can be released by moving the outward insertion rod 44. Then, by gripping the handle 52 and pulling the base plate 5, the sand and gravel material in the truck bed 1 falls out as the base plate 5 gradually retracts. The remaining sand and gravel is then emptied by pulling the vehicle body. The bottom plate 5 is then reinstalled by reversing the operation. Compared to existing transport trolleys, this method avoids sand and gravel falling through gaps and causing damage. This method avoids waste and is more efficient and labor-saving. With the electromagnet 42 and tension spring 41, the tension spring 41 can apply force to the insertion rod 44, making the insertion rod 44 stably inserted into the slot 53. If the insertion rod 44 needs to be moved outward, the electromagnet 42 can be turned on. The electromagnet 42 generates a magnetic field and attracts the iron block 43, causing the insertion rod 44 to move outward and temporarily limit it. Conversely, when the electromagnet 42 is turned off, the tension spring 41 can make the insertion rod 44 return to its original position. This structural design has a convenient insertion rod 44 adjustment function and the use effect is quite ideal.
