Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figures 1 to 3 As shown, the utility model provides a sorting component for road and bridge construction materials, including a support column 1, a material receiving hopper 2, a placement rail 3, a movable plate 4 and a screening box 5. The top of the support column 1 is fixedly connected to the bottom of the placement rail 3, the front of the support column 1 is movably connected to the back of the material receiving hopper 2, the inner side of the placement rail 3 is slidably connected to the two sides of the movable plate 4, the top of the movable plate 4 is fixedly connected to the bottom of the screening box 5, the bottom of the inner wall of the screening box 5 is slidably connected with a screening plate 6, the top of the screening plate 6 is fixedly connected to a connecting column 7, the top of the connecting column 7 is fixedly connected to an auxiliary frame 8, a connecting component 9 is provided at the bottom of the surface of the screening box 5, and a limiting component 10 is provided at the bottom of the surface of the screening box 5.
[0023] refer to Figure 3 The connecting component 9 includes a connecting groove 91, a movable groove 92 and a connecting block 93. The connecting groove 91 is opened on both sides of the front and back of the screening plate 6, and the movable grooves 92 are opened on both sides of the bottom of the front and back of the screening box 5. The movable groove 92 is connected to the connecting groove 91, and the surface of the connecting block 93 is slidably connected to the inner wall of the connecting groove 91, and the surface of the connecting block 93 is slidably connected to the inner wall of the movable groove 92.
[0024] As a technical optimization scheme of the utility model, by setting the connecting component 9, when the user puts the screening plate 6 back into the screening box 5, the connecting block 93 is first moved to the outside of the surface of the movable groove 92, so that the connecting block 93 does not protrude from the inner wall of the screening box 5, and then the screening plate 6 is placed into the screening box 5, so that the movable groove 92 is aligned with the connecting groove 91. At this time, the user pushes the connecting block 93 toward the screening plate 6 to move the connecting block 93 into the connecting groove 91, and uses the connecting block 93 to limit the up and down movement of the screening plate 6, thereby avoiding the automatic movement of the screening plate 6 when the screening plate 6 vibrates.
[0025] refer to Figure 3 The limit assembly 10 includes a slide groove 101 and a slider 102. The slide grooves 101 are opened on both sides of the movable groove 92. The surface of the slider 102 is slidably connected to the inner wall of the slide groove 101, and the inner side of the slider 102 is fixedly connected to both sides of the connecting block 93.
[0026] As a technical optimization solution of the utility model, by setting a limit assembly 10, when the user moves the connecting block 93 out of the connecting groove 91, the connecting block 93 will drive the slider 102 to move, and the slide groove 101 will be used to limit the moving direction and moving distance of the slider 102, thereby limiting the final moving distance of the connecting block 93, thereby avoiding the situation where the slider 102 moves out of the moving groove 92.
[0027] refer to Figure 3 Limiting plates 11 are provided on both sides of the connecting block 93, the outer side of the limiting plates 11 is fixedly connected to the inner wall of the movable groove 92, the front side of the slider 102 is fixedly connected to a spring 12, and the end of the spring 12 away from the slider 102 is fixedly connected to the inner wall of the slide groove 101.
[0028] As a technical optimization solution of the utility model, by setting a limit block and a spring 12, when the slider 102 moves, the spring 12 will be squeezed to shrink, and then the limit plate 11 can be used to prevent the spring 12 from popping out of the slide groove 101 after shrinking, so that the spring 12 can shrink stably. When the user releases the connecting block 93, the rebound force of the spring 12 is used to return the connecting block 93 to its original position, thereby facilitating the user to use the connecting block 93.
[0029] refer to Figure 2 A buffer pad 13 is fixedly connected to the inner wall of the screening box 5, and the material of the buffer pad 13 is rubber.
[0030] As a technical optimization solution of the utility model, by setting the buffer pad 13, when the user places sand and gravel into the screening box 5, larger stone particles will be screened out by the screening plate 6. Since the vibration of the screening box 5 will drive the stone particles to vibrate, the buffer pad 13 can reduce the impact of the stone particles on the screening box 5, thereby reducing the noise generated by the stone particles.
[0031] refer to Figure 2 The outer side of the slider 102 is fixedly connected with an auxiliary rod 14, and the shape of the auxiliary rod 14 is irregular.
[0032] As a technical optimization solution of the utility model, by setting the auxiliary rod 14, when the user needs to pull the connecting block 93 out of the movable groove 92, the auxiliary rod 14 can be used to increase the contact area between the user and the connecting block 93, thereby avoiding the situation where the user is inconvenient to pull out the connecting block 93. The irregular shape of the auxiliary rod 14 can be used to increase the friction between the user and the auxiliary rod 14, thereby facilitating the user to pull out the connecting block 93.
[0033] refer to Figure 2 The front and back sides of the auxiliary frame 8 are movably connected with a lifting rod 15 through an axle pin, and an auxiliary sleeve 16 is fixedly sleeved on the surface of the lifting rod 15.
[0034] As a technical optimization solution of the utility model, by providing a lifting rod 15 and an auxiliary sleeve 16, when the user lifts the screening plate 6 out of the screening box 5, the user flips the auxiliary rod 14 upward to make the auxiliary rod 14 stand upright, which is convenient for the user to use the auxiliary rod 14 to take the screening plate 6 out of the screening box 5, and then the auxiliary sleeve 16 can be used to increase the friction between the user and the auxiliary rod 14, making it easier for the user to lift the screening plate 6.
[0035] The working principle and use process of the utility model are as follows: during the long-term use of the screening box 5, a large number of stone particles will be blocked on the screening plate 6. The auxiliary rod 14 is first used to increase the contact area between the user and the connecting block 93 to avoid the situation where the user is inconvenient to pull out the connecting block 93. The irregular shape of the auxiliary rod 14 is then used to increase the friction between the user and the auxiliary rod 14 to move the connecting block 93 out of the connecting groove 91. When the user moves the connecting block 93 out of the connecting groove 91, the connecting block 93 drives the slider 102 to move. The slide groove 101 is used to limit the moving direction and moving distance of the slider 102, thereby limiting the final moving distance of the moving block 93. When the slider 102 moves, it squeezes the spring 12 to make the spring 12 contract. The limit plate 11 can prevent the spring 12 from popping out of the slide slot 101 after shrinking, so that the spring 12 can shrink stably. When the user releases the connecting block 93, the resilience of the spring 12 is used to return the connecting block 93 to its original position. When the user puts the screening plate 6 back to its original position, the connecting block 93 is first moved to the outside of the surface of the movable groove 92 so that the connecting block 93 does not protrude from the inner wall of the screening box 5, and then the screening plate 6 is placed into the screening box 5 so that the movable groove 92 is aligned with the connecting groove 91. At this time, the user pushes the connecting block 93 toward the screening plate 6 to move the connecting block 93 into the connecting groove 91, and uses the connecting block 93 to limit the up and down movement of the screening plate 6 to avoid the automatic movement of the screening plate 6 when the screening plate 6 vibrates, thereby achieving the effect of easy cleaning.
[0036] In summary: the sorting component of the road and bridge construction materials is provided with an auxiliary frame 8. During the long-term use of the screening box 5, the screening plate 6 inside the screening box 5 will be blocked by a large number of stone particles. The auxiliary frame 8 is used to facilitate the user to remove the screening plate 6 from the screening box 5, thereby solving the problem that a large number of stone particles will be filtered out of the screening box, which will affect the screening efficiency of the screening machine. Since the screening machine is not provided with a device for the user to remove the screening plate from the screening box, it is inconvenient for the user to clean the stone particles passing through the screening box.
