Technical Field
[0001] This utility model relates to the field of material conveying devices, and more particularly to a material conveying device for the bottom belt of a belt conveyor. Background Technology
[0002] In coal mine production, tunneling roadways are channels formed for exploration and mining. Coal mining faces need to be equipped with transport roadways (passageways for materials and equipment). Transport roadway flooring work refers to pouring concrete or hardening the ground in the roadway to ensure that it is flat and solid to support the passage of transport vehicles, prevent water accumulation and dust, and ensure the stability of the roadway structure and the safety of operations.
[0003] However, in the construction of tunnels or coal mining face transport roadways, one problem is that the pedestrian space on the tunnel side is narrow, making it difficult for transport vehicles to directly deliver the required mixture to the work area. In the past, people had to put the mixture into bags and then use the bottom belt of a conveyor belt to transport these bagged materials to the construction site. However, this method is not only costly in terms of labor, but also inefficient. Utility Model Content
[0004] In order to overcome the problem that transport vehicles cannot directly reach the work area due to the narrow pedestrian side of the tunnel during construction tunneling or coal mining face transportation, the previous method of transporting bagged mixed materials via the bottom belt of a belt conveyor resulted in high costs and low efficiency.
[0005] The technical solution of this utility model is as follows: a belt conveyor bottom belt conveying device, including a working face belt conveyor and a loading belt conveyor, and a feeding hopper set on the upper side of the loading belt conveyor. The feeding hopper receives the mixed material through a loader, and the mixed material falls onto the loading belt conveyor through the feeding hopper. A guide plate is set at one end of the loading belt conveyor near the working face belt conveyor, and the mixed material is transferred to the bottom belt of the working face belt conveyor through the guide plate. A moving module is set on one side of the working face belt conveyor, and a lifting module is connected to the moving module. The lifting module moves through the moving module... The moving module moves along the long side of the working face belt conveyor. The lifting module is connected to a mounting base, and an electric push rod is installed on the side of the mounting base. The power output end of the electric push rod is equipped with a coal unloading plate. The inclined surface of the coal unloading plate is used to unload the mixture from the bottom belt of the working face belt conveyor. The moving module includes a transmission unit set on the ground and a sliding unit connected to the transmission unit. The transmission unit is guided by the sliding unit. The lifting module includes an adjustment unit connected to the transmission unit and an operating unit connected to the adjustment unit. The adjustment unit drives the lifting through the operating unit.
[0006] Preferably, the transmission unit includes a support plate 1 and a support plate 2 installed on the ground. A bearing seat 1 is provided on the end face of the support plate 1, and a servo motor is provided on the end face of the support plate 2. A lead screw 1 connected to the output shaft of the servo motor is rotatably connected inside the bearing seat 1, and a movable seat with an internal cavity is threadedly connected to the outer wall of the lead screw 1.
[0007] Preferably, the sliding unit includes a slide rail disposed on the ground, a slider slidably connected on the slide rail, and the surface of the slider being connected to the lower end of the movable seat.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of a belt conveyor bottom belt conveying device, including a working face belt conveyor 1 and a loading belt conveyor 2, and further including a feeding hopper 3 disposed on the upper side of the loading belt conveyor 2. The feeding hopper 3 receives the mixture through a loader, and the mixture falls onto the loading belt conveyor 2 through the feeding hopper 3. A guide plate 4 is disposed at one end of the loading belt conveyor 2 near the working face belt conveyor 1, and the mixture is transferred to the bottom belt of the working face belt conveyor 1 through the guide plate 4. A bottom belt conveyor is disposed on one side of the working face belt conveyor 1. The system includes a moving module and a lifting module connected to it. The lifting module moves along the long side of the working face belt conveyor 1 via the moving module. A mounting base 5 is connected inside the lifting module. An electric push rod 6 is installed on the side of the mounting base 5. A coal unloading plate 7 is installed at the power output end of the electric push rod 6. The inclined surface of the coal unloading plate 7 is used to unload the mixture from the bottom belt of the working face belt conveyor 1. The moving module includes a transmission unit installed on the ground and a sliding unit connected to the transmission unit. The transmission unit is guided by the sliding unit.The lifting module includes an adjustment unit connected to the transmission unit and an operating unit connected to the adjustment unit. The adjustment unit drives the lifting via the operating unit. The working face belt conveyor 1 and the loading belt conveyor 2 are responsible for conveying the mixture. The working face belt conveyor 1 transports the mixture from the loading point to the designated unloading position, while the loading belt conveyor 2 mainly serves as a transition point, receiving the mixture from the feed hopper 3 and transferring it to the bottom belt of the working face belt conveyor 1. The feed hopper 3 serves as the inlet for the mixture to enter the loading belt conveyor 2, receiving the mixture from the loader. The mixture is fed to the loading belt conveyor 2. The feeding hopper 3 has a certain volume and a specific shape (such as a funnel). Its upper opening is large to facilitate the loader to pour the mixture in smoothly. The lower opening matches the width of the conveyor belt of the loading belt conveyor 2 to ensure that the mixture can fall evenly and stably onto the conveyor belt. The feed plate 4 is used to smoothly and accurately transfer the mixture from the loading belt conveyor 2 to the bottom belt of the working face belt conveyor 1, avoiding spillage of the mixture during the transfer process. The feed plate 4 is inclined, with one end connected to the bottom belt of the working face belt conveyor 1. The conveyor belt of the loading belt conveyor 2 is connected at one end, and the other end extends above the bottom belt of the working face belt conveyor 1. When the mixture moves to the end with the loading belt conveyor 2, due to inertia and the guidance of the feed plate 4, the mixture will slide down the inclined surface of the feed plate 4 onto the bottom belt of the working face belt conveyor 1. The moving module provides the lifting module with the ability to move along the long side of the working face belt conveyor 1, so that the unloading plate 7 can perform unloading operations at different positions of the working face belt conveyor 1, thereby meeting the unloading requirements at different positions. The lifting module is adjusted and installed... The height of the mounting base 5 allows the unloading plate 7 to be adjusted according to the height of the bottom belt of the working face belt conveyor 1 and the unloading requirements, thereby achieving unloading. The mounting base 5 serves as the mounting foundation for the electric push rod 6, providing stable support and a fixed position for it. The electric push rod 6 pushes the unloading plate 7 to extend and retract, thus extending the unloading plate 7 onto the bottom belt of the working face belt conveyor 1. When the mixed material on the bottom belt of the working face belt conveyor 1 moves to the position of the unloading plate 7, due to the blocking and guiding effect of the inclined surface of the unloading plate 7, the mixed material will move along the inclined surface, thereby achieving unloading.
[0022] Please see Figure 3In this embodiment, the transmission unit includes a support plate 8 and a support plate 9 mounted on the ground. A bearing seat 10 is mounted on the end face of support plate 8, and a servo motor 11 is mounted on the end face of support plate 9. A lead screw 12, connected to the output shaft of the servo motor 11, is rotatably connected inside the bearing seat 10. A movable seat 13 with an internal cavity is threaded onto the outer wall of the lead screw 12. The sliding unit includes a slide rail 14 mounted on the ground, and a slider 15 is slidably connected to the slide rail 14. The surface of the slider 15 is connected to the lower end of the movable seat 13. Support plates 8 and 9 are made of robust metal and are fixed to the ground by welding, bolting, or other methods. The bearing seat 10 supports one end of the lead screw 12, enabling stable rotation of the lead screw 12 within it. A bearing is installed inside the bearing seat 10, and the outer ring of the bearing is connected to the bearing seat 10. The inner hole of the bearing is tightly fitted, and the inner ring of the bearing is tightly fitted with the outer wall of the lead screw 12. When the lead screw 12 is driven by the servo motor 11 to rotate, the bearing can withstand the radial and axial forces of the lead screw 12, so that the lead screw 12 rotates smoothly in the bearing seat 10. The outer wall of the lead screw 12 has threads, and the moving seat 13 has an internal thread that matches it. When the lead screw 12 rotates under the drive of the servo motor 11, due to the helical side effect of the thread, the moving seat 13 will move linearly along the axial direction of the lead screw 12, and drive the lifting module to move along the long side of the working surface belt conveyor 1. The slide rail 14 provides a guide track for the sliding of the slider 15. The slider 15, as the moving part of the sliding unit, is connected to the lower end of the moving seat 13 and slides on the slide rail 14 to ensure that the entire moving module can move smoothly and steadily.
[0023] Please see Figure 4In this embodiment, the adjustment unit includes a bearing seat 16 at the bottom of the cavity, a lead screw 17 rotatably connected inside the bearing seat 16, a lifting seat 18 threadedly connected to the outer wall of the lead screw 17, and the upper end of the lifting seat 18 connected to the lower end of the mounting seat 5. The operation unit includes a bearing seat 19 on the inner wall of the cavity, a worm gear 20 rotatably connected inside the bearing seat 19, a knob 21 at the end of the worm gear 20, a worm wheel 22 on the outer wall of the lead screw 17, and the worm gear 20 meshing with the worm wheel 22. The bearing seat 16 is used for... At the lower end of the supporting lead screw 17, a bearing is installed inside the bearing housing 16, similar to the bearing housing 10. The outer ring of the bearing is tightly fitted with the inner hole of the bearing housing 16, and the inner ring of the bearing is tightly fitted with the outer wall of the lead screw 17. When the lead screw 17 is driven to rotate by the operating unit, the bearing can withstand the radial and axial forces of the lead screw 17, allowing the lead screw 17 to rotate smoothly within the bearing housing 16. The outer wall of the lead screw 17 has threads, and the lifting seat 18 has internal components... The corresponding internal thread, when the lead screw 2 17 rotates under the drive of the operating unit, due to the helical side effect of the thread, the lifting seat 18 will move linearly along the axial direction of the lead screw 2 17. The bearing seat 3 19 is used to support one end of the worm 20, so that the worm 20 can achieve stable rotation inside it. The bearing seat 3 19 is equipped with a bearing. The outer ring of the bearing is tightly fitted with the inner hole of the bearing seat 3 19, and the inner ring of the bearing is tightly fitted with the outer wall of the worm 20. When the worm 20 is driven by the knob 21 to rotate, the bearing can... It can withstand the radial and axial forces of the worm 20, allowing the worm 20 to rotate smoothly within the bearing housing 19, ensuring that the worm 20 and worm wheel 22 can mesh and transmit power normally, thereby driving the lead screw 17. As the power transmission component of the operating unit, the worm 20 transmits the rotational motion of the knob 21 to the lead screw 17 through meshing with the worm wheel 22, thereby driving and controlling the lead screw 17 and adjusting the lifting height of the lifting seat 18. The worm 20 also has a self-locking function, which can prevent the lead screw 17 from rotating when it stops rotating.
[0024] Please see Figure 4In this embodiment, a groove 24 is provided on the inner wall of the cavity, and a convex rail 23 is integrally provided on the side wall of the lifting seat 18. The convex rail 23 is slidably connected to the groove 24. The surface of the knob 21 is provided with a rubber skin with anti-slip texture. The groove 24 is provided on the inner wall of the cavity to provide a sliding track for the convex rail 23 of the lifting seat 18, which guides the lifting movement of the lifting seat 18 and ensures that the lifting seat 18 maintains stable linear movement during the lifting process. The rubber skin increases the friction, making it easier and less strenuous for the operator to turn the knob 21. The anti-slip texture on the rubber skin further increases the friction coefficient of the knob 21 surface and improves the anti-slip performance when the operator turns the knob 21. Especially when the operator's hands are sweaty or oily, the anti-slip texture can effectively prevent the hand from slipping between the hand and the knob 21.
[0025] Working principle: First, the loader pours the mixture into the feed hopper 3. The feed hopper 3 receives and guides the mixture to fall evenly and stably onto the loading belt conveyor 2. The loading belt conveyor 2 starts and transports the mixture along its conveyor belt towards the working face belt conveyor 1. When the mixture reaches the end of the loading belt conveyor 2, due to the inclined design of the feed plate 4 and the inertial effect, the mixture slides down smoothly and accurately and is transferred to the bottom belt of the working face belt conveyor 1.
[0026] At this time, the working face belt conveyor 1 starts to operate, continuing to transport the mixture forward. As needed for the unloading position, the moving module starts to work. The servo motor 11 drives the lead screw 12 to rotate. Through the spiral side effect of the thread, the moving seat 13 drives the lifting module to move smoothly and steadily to the designated position along the slide rail 14 set on the ground.
[0027] Next, the operating unit begins to adjust the height of the lifting seat 18 to adapt to the height of the bottom belt of the working face belt conveyor 1 and the unloading requirements. The knob 21 is turned, and the knob 21 drives the worm 20 to rotate smoothly in the bearing seat 19. The meshing transmission between the worm 20 and the worm wheel 22 transmits the rotational motion to the lead screw 17. When the lead screw 17 rotates, the lifting seat 18 moves linearly along the axial direction of the lead screw 17. At the same time, the convex rail 23 of the lifting seat 18 slides in the slide groove 24 to ensure the stability of the lifting process.
[0028] After the lifting seat 18 is adjusted to the appropriate height, the electric push rod 6 is started, pushing the unloading plate 7 to extend and retract, extending the unloading plate 7 into the bottom belt of the working face belt conveyor 1. When the mixed material on the bottom belt moves to the position of the unloading plate 7, due to the blocking and guiding effect of the inclined surface of the unloading plate 7, the mixed material moves along the inclined surface and is unloaded.
[0029] Through the above steps, the mixture can be delivered smoothly and accurately to the unloading point, eliminating the need for manual bagging and handling, saving manpower and time. Its flexible movement and lifting functions can better meet diverse unloading needs and different bottom belt heights, improving transportation flexibility and adaptability. It solves the problem of high cost and low efficiency caused by the previous use of bagged mixtures transported via belt conveyor bottom belt when transporting them in construction tunnels or coal mining faces, where the narrow pedestrian side of the tunnel makes it difficult for transport vehicles to reach the work area directly.
