It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model.

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-6 As shown, the present invention proposes a stone conveying device to prevent falling stones, including a frame 1, a conveyor belt 2 installed inside the frame 1, horizontal plates 3 installed on both the left and right sides of the conveyor belt 2, vertical plates 4 installed on the top of the two horizontal plates 3, side protection mechanisms 5 provided on the opposite side of the two vertical plates 4, and a top protection mechanism 6 provided on the top of the conveyor belt 2.

[0026] In this invention, the conveyor belt 2 can be installed on the frame 1, while the side protection mechanism 5 and the top protection mechanism 6 can be installed on the horizontal plate 3 and the vertical plate 4. The side protection mechanism 5 can protect both sides of the conveyor belt 2, so that the conveyor belt 2 forms a relative channel through the side protection mechanism 5, which restricts the lateral movement of the stones during the conveying process and prevents the stones from falling from both sides of the conveyor belt. The top protection mechanism 6 can protect the top of the conveyor belt 2 to prevent the stones from falling due to jumping and rolling during the conveying process, which greatly improves the safety and stability of the conveying process.

[0027] like Figure 1-3 As shown, in an optional embodiment, the top protection mechanism 6 includes two fixed plates 61, two sets of lifting components 62, two mounting plates 63, a U-shaped frame 64, and multiple pressure rollers 65. The two fixed plates 61 are respectively installed on the top of the two vertical plates 4, and the two mounting plates 63 are respectively located above the two fixed plates 61. The two sets of lifting components 62 are respectively disposed inside the two fixed plates 61, and the two sets of lifting components 62 are respectively connected to the two mounting plates 63 to drive the two mounting plates 63 to lift. The U-shaped frame 64 is installed between the opposite sides of the two mounting plates 63, and the multiple pressure rollers 65 are rotatably connected between the left and right side walls of the inner cavity of the U-shaped frame 64 and are evenly distributed.

[0028] The U-shaped frame 64 and multiple pressure rollers 65 can be installed using two fixed plates 61, two sets of lifting components 62, and two mounting plates 63. The top of the conveyor belt 2 can be protected by the U-shaped frame 64 and multiple pressure rollers 65. During the conveying process, the stones conveyed on the top of the conveyor belt 2 are blocked by multiple pressure rollers 65. When the stones bounce, they will touch the multiple pressure rollers 65 above them. The rolling of the multiple pressure rollers 65 not only prevents the stones from jumping up, but also ensures the normal transportation of the stones through their own rolling, avoiding the stones from falling due to jumping and rolling during the conveying process, which greatly improves the safety and stability of the conveying process.

[0029] like Figure 4-5 As shown, in an optional embodiment, both sets of lifting components 62 include a sliding groove 621, a lifting plate 622, a limiting module 623, a fixing block 624, and an electric telescopic rod 625. The two sliding grooves 621 are respectively opened on the top of the two fixing plates 61, and the two lifting plates 622 are slidably connected to the inside of the two sliding grooves 621. The two sets of limiting modules 623 are respectively disposed on the outer end face of the lifting plate 622. The opposite side of the two lifting plates 622 is respectively connected to the opposite side of the two mounting plates 63. The two fixing blocks 624 are respectively installed on the opposite side of the two lifting plates 622, and the two electric telescopic rods 625 are respectively installed on the opposite side of the two fixing plates 61. The piston rods of the two electric telescopic rods 625 are respectively connected to the bottom of the two fixing blocks 624.

[0030] When both electric telescopic rods 625 are activated simultaneously, their piston rods will drive the two fixed blocks 624 to move up or down, respectively. The two fixed blocks 624 will then drive the two lifting plates 622 to move up or down, respectively. This allows the lifting plates 622 to slide within the sliding groove 621, adjusting their height. The two lifting plates 622 can then drive the two mounting plates 63 to move up or down, respectively. The two mounting plates 63 will then drive the U-shaped frame 64 and multiple pressure rollers 65 to move up or down, adjusting their height. This allows the multiple pressure rollers 65 to adapt to limiting the height of the stone top at different transmission heights, improving the applicability of the top protection mechanism 6.

[0031] like Figure 5 As shown, in an optional embodiment, the limiting module 623 includes two limiting grooves 6231 and two limiting blocks 6232. The two limiting grooves 6231 are respectively opened on the front and rear side walls of the inner cavity of the sliding groove 621, and the two limiting blocks 6232 are respectively installed on the front and back of the lifting plate 622. The two limiting blocks 6232 are slidably connected to the inside of the two limiting grooves 6231.

[0032] When the lifting plate 622 slides inside the sliding groove 621, the lifting plate 622 can be limited by the two limiting grooves 6231 and the two limiting blocks 6232, which ensures the stability of the movement of the lifting plate 622 and prevents the lifting plate 622 from disengaging from the sliding groove 621 during movement.

[0033] like Figure 1 and Figure 6 As shown, in an optional embodiment, both sets of side protection mechanisms 5 include cylinders 51, movable plates 52, two guide rods 53, multiple springs 54, and baffle plates 55. The two cylinders 51 are respectively installed on opposite sides of the two vertical plates 4 and extend to their opposite sides. The two movable plates 52 are respectively installed on the piston rods of the two cylinders 51. The two guide rods 53 are respectively installed on opposite sides of the two movable plates 52 and extend to opposite sides of the two vertical plates 4. The guide rods 53 are slidably connected to the vertical plates 4. The multiple springs 54 are respectively installed on opposite sides of the two movable plates 52. The two baffle plates 55 are respectively installed on opposite sides of the two movable plates 52 through the springs 54.

[0034] When conveying stones via conveyor belt 2, two cylinders 51 are activated according to the amount of stones to be conveyed. The piston rods of the two cylinders 51 will drive the two movable plates 52 to move to opposite sides respectively. The two movable plates 52 will drive the two baffle plates 55 to move to opposite sides respectively through springs 54. Thus, the two baffle plates 55 limit the two sides of the stones. The conveyor belt 2 and the two baffle plates 55 form a relative channel, restricting the lateral movement of the stones during the conveying process and preventing the stones from falling from the sides of the conveyor belt.

[0035] When the movable plate 52 moves, the two guide rods 53 can guide the movable plate 52 to ensure the stability of the movement of the movable plate 52, thereby ensuring the stability of the baffle plate 55 during movement.

[0036] Meanwhile, when the stone is limited on both sides by the two baffles 55, the spring 54 can buffer the baffles 55, thereby reducing the impact of the stone on the baffles 55 and improving the service life of the baffles 55.

[0037] like Figure 1 As shown, in an optional embodiment, the movable plate 52 is adapted to the baffle plate 55, and the bottom horizontal position of the baffle plate 55 is higher than the top horizontal position of the conveyor belt 2 to ensure that the movement of the movable plate 52 and the baffle plate 55 will not limit the movement of the conveyor belt 2. The bottom horizontal position of the pressure roller 65 is higher than the top horizontal position of the baffle plate 55, which can prevent the pressure roller 65 from being limited by the baffle plate 55 when it is moving up and down.

[0038] Working principle:

[0039] In this anti-fall stone conveying device, stones are conveyed via conveyor belt 2. First, two cylinders 51 are activated according to the amount of stone being conveyed, causing two baffle plates 55 to move to opposite sides. These baffle plates 55 limit the stones on both sides, forming a channel between the conveyor belt 2 and the two baffle plates 55, restricting lateral movement of the stones during conveying and preventing them from falling off the conveyor belt. Then, two electric telescopic rods 625 are activated according to the stone's conveying height, causing multiple pressure rollers 65 to move upwards or downwards. This adjusts the height of the U-shaped frame 64 and the multiple pressure rollers 65, allowing them to limit the top of stones at different conveying heights, improving the applicability of the top protection mechanism 6. Simultaneously, the multiple pressure rollers 65 protect the top of the conveyor belt 2, preventing stones from falling due to jumping or rolling during conveying, greatly improving the safety and stability of the conveying process.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
