Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a material transport device for processing potassium feldspar. Background Art

[0002] Potassium feldspar belongs to the monoclinic crystal system and typically appears in colors ranging from flesh-red to yellowish-white. Its relatively low melting point, long melting interval, and high melt viscosity make it widely used in industrial applications such as ceramic blanks, glazes, glassmaking, electrical porcelain production, and abrasive material preparation, as well as in potash fertilizer manufacturing.

[0003] In actual production, potassium feldspar undergoes a series of processing steps, including cleaning, impurity removal, and crushing. During this process, potassium feldspar must be transported multiple times to achieve the desired processing location. Generally, potassium feldspar transportation is primarily accomplished using conveyor belts, which are particularly crucial when transferring materials at different heights.

[0004] Currently, existing conveyor belts are typically equipped with a steel support frame at the bottom end, and a corresponding drive mechanism is installed on one side of the conveyor belt. However, these existing devices have shortcomings in their positional control. Whether the drive mechanism is operating or material is pouring onto the conveyor belt end, it will cause significant vibrations on the conveyor belt, causing the material to jump on the conveyor belt or even separate from the conveyor belt.

[0005] Therefore, in order to effectively avoid material waste and reduce the difficulty of subsequent cleaning, this device believes that there is an urgent need for a material transportation device for potassium feldspar processing that can effectively limit the material on the conveyor belt. Utility Model Content

[0006] In response to the shortcomings of current technologies, this utility model proposes a material transport device for potassium feldspar processing. This device effectively limits the material during movement, effectively preventing it from separating from the conveyor belt. This solves the problem in existing technologies where the lack of limiting measures can easily lead to material separation from the conveyor belt, resulting in waste of resources.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Please refer to Figure 1As shown, a material transport device for potassium feldspar processing has the same structure as the prior art device, and mainly comprises a support frame 1. The support frame 1 is the basic structure of the device, and its main function is to provide a stable support.

[0023] A conveyor belt 2 is fixedly installed on the top of the support frame 1, and a drive mechanism is configured on one side of the conveyor belt 2. The design of the drive mechanism ensures that the material can move smoothly along the conveyor belt 2.

[0024] In actual production processes, the primary function of conveyor belt 2 is to transfer materials between different heights. Therefore, the overall shape of support frame 1 is designed as a right-angled trapezoid, with the hypotenuse located at its upper end. This design creates a certain inclination angle at the horizontal centerline of conveyor belt 2, thereby achieving the material height transfer function.

[0025] Specifically, the support frame 1 is composed of a frame body arranged at the bottom, and a U-shaped steel frame with a vertical plane projection of a U shape and U-shaped openings facing each other is installed on the front and rear sides of the upper end of the frame body. The two U-shaped steel frames are used to fix the conveyor belt 2.

[0026] The drive mechanism also consists of two driven rollers 6, arranged axially in a front-to-rear manner. These two driven rollers 6 are inserted into the inner ends of the conveyor belt 2 and form an interference fit with the conveyor belt 2. This design ensures that when a single driven roller 6 rotates, it can drive the conveyor belt 2 in a circular motion.

[0027] like Figure 1 As shown, a drive motor is provided at the upper end of the support frame 1, and the output shaft of the drive motor is connected to one of the driven rollers 6. This design ensures that the drive motor can effectively drive the conveyor belt 2 to move when in working condition.

[0028] In addition, if Figure 2 and Figure 4 As shown, compared to prior art devices, this device incorporates multiple limiting wheels 16, which are evenly spaced above the conveyor belt 2 along its length. By ensuring that each limiting wheel 16 is located in the same vertical plane as the vertical centerline of the conveyor belt 2, and that the distance from the side end of the driven roller 6 to the horizontal centerline of the conveyor belt 2 is less than the distance from the side end of the limiting wheel 16 to the horizontal centerline of the conveyor belt 2, the limiting wheels 16 exert a downward pressure on the middle portion of the upper end of the conveyor belt 2. This design aims to ensure that as the material moves along the conveyor belt 2, through the stable control of the limiting wheels 16, the material will spontaneously move toward the middle of the conveying section due to the inclined surface of the upper end of the conveyor belt 2 and its gravitational potential energy, thereby ensuring that the material does not deviate from the predetermined path during transportation.

[0029] Specifically, each limiting wheel 16 of this device is coaxially fixedly connected to a support roller 4 to provide additional support and stability. The two ends of the support roller 4 are connected to the support base 8 via a rotational connection, and the support base 8 is fixedly connected to the support frame 1, thereby ensuring the structural stability of the entire device.

[0030] Furthermore, if Figure 3 、 Figure 4 As shown, to prevent the problem of the material being unable to move toward the middle section of the conveyor belt 2 due to the small particle size of a single material, where the horizontal component of its gravitational potential energy generated by the inclined surface at the upper end of the conveyor belt 2 is smaller than the frictional resistance between the material and the conveyor belt 2, the present device is equipped with multiple follower shafts 13 on the front and rear sides of the support frame 1. These follower shafts 13 are arranged parallel and equidistantly along the length of the conveyor belt 2. Each follower shaft 13 is axially oriented and is rotatably connected to the support frame 1, ensuring its flexible adaptation to material conveying needs.

[0031] At the same time, the end of each follower shaft 13 closest to the conveyor belt 2 is constrained and embedded within the conveyor belt 2, and this portion is coaxially fixedly connected to the cam 10. By design, the distance between the central axis of each follower shaft 13 and the lower sidewall of the upper end of the conveyor belt 2, which lies in the same vertical plane, is less than the distance between the outer protrusion of the cam 10 and the central axis of the follower shaft 13. This design allows the cam 10 to strike the upper end of the conveyor belt 2 upward during rotation, further increasing the inclination angle of the upper end of the conveyor belt 2. This not only strengthens the horizontal component of the material's force due to the inclined surface, but also provides the material and conveyor belt 2 with additional upward thrust during the impact. When this thrust dissipates, the conveyor belt 2 and the material move downward. Due to the different constraints, the conveyor belt 2 separates from the material. As the material bounces on the conveyor belt 2, its gravitational potential energy increases, while the contact area between the material and the conveyor belt 2 decreases, resulting in reduced frictional resistance. This ensures that the material can smoothly move toward the middle of the conveyor belt 2 under the impact of the cam 10.

[0032] It is important to note that, in actual use, an interference fit must be achieved between the limiting wheel 16 and the conveyor belt 2 to ensure that the middle section of the conveyor belt 2 is sunken. During this process, significant frictional resistance is generated between the limiting wheel 16 and the conveyor belt 2. Therefore, as the conveyor belt 2 moves, the limiting wheel 16 will continuously rotate in a single direction.

[0033] In view of this, in order to efficiently utilize resources, this device adopts a transmission connection method to constrain the support roller 4 and the follower shaft 13.

[0034] Furthermore, to prevent the cam 10 from compressing the lower end of the conveyor belt 2, thereby tightening the entire conveyor belt 2 and reducing the inclination of the upper end of the conveyor belt 2, a driven shaft 15 is provided on one side of each support roller 4, extending in a forward and backward direction and rotationally connected to the support frame 1. One axial end of the driven shaft 15 is eccentrically fixedly connected to the driven rod 14. Simultaneously, a transmission connection is established between the driven shaft 15 and the corresponding support roller 4.

[0035] Furthermore, each follower shaft 13 is eccentrically fixedly connected to a follower rod 11 on the side facing away from the conveyor belt 2. A transmission rod 12 is positioned between the follower rod 11 and the corresponding driven rod 14. Each transmission rod 12 is rotationally connected to both the corresponding driven rod 14 and the follower rod 11, ensuring efficient power transmission to each component. This design, leveraging the transmission action of the transmission rod 12, drives the driven shaft 15 to rotate as the support roller 4 continuously rotates, thereby causing the follower shaft 13 to oscillate, ensuring that the cam 10 only strikes the upper end of the conveyor belt 2.

[0036] Specifically, the device is provided with a transmission belt 9 on the outer side of each axial end of each support roller 4, and the other end of the transmission belt 9 is sleeved on the outer side of the corresponding driven shaft 15. This design is intended to achieve effective power transmission between the support roller 4 and the driven shaft 15.

[0037] Furthermore, in order to increase the friction resistance between the limiting wheel 16 and the conveyor belt 2, the device adds a contact wheel 5 made of rubber material on the outside of the limiting wheel 16 to provide better friction and stability.

[0038] At the same time, anti-skid grooves 7 are designed to penetrate the front and rear sides of the side ends of the contact wheel 5 to further increase the contact area, thereby effectively improving the friction resistance.

[0039] Furthermore, multiple anti-slip strips 3 are arranged equidistantly and parallel to the outer end of the conveyor belt 2. These anti-slip strips 3 are all located in the same vertical plane as the contact wheel 5. By utilizing the anti-slip strips 3's protrusion from the upper end surface of the conveyor belt 2, the compressive force between the anti-slip strips 3 and the contact wheel 5 is enhanced when they abut against each other, and the corresponding interaction force is also stronger, ensuring that the contact wheel 5 closely follows the movement of the conveyor belt 2. Furthermore, the provision of the anti-slip strips 3 further enhances the stability of the material during conveyance.

[0040] During actual use, the utility model:

[0041] The synergistic effect of the driving mechanism and the support frame 1 ensures that the conveyor belt 2 achieves circular motion. In addition, a plurality of evenly distributed limiting wheels 16 are added to the upper end of the conveyor belt 2. The stable control function of the limiting wheels 16 is utilized to ensure that the material moves along the predetermined path. At the same time, the device is provided with a plurality of follower shafts 13 on the front and rear sides of the support frame 1, and the ends of the follower shafts 13 are embedded in the inner side of the conveyor belt 2 and are coaxially fixedly connected to the cam 10. The rotational movement of the cam 10 can slap the upper end of the conveyor belt 2. This design can increase the inclination angle of the material and enhance the horizontal component of the material, thereby ensuring the smooth movement of the material. In addition, the device is provided with a driven shaft 15 that is transmission-connected to the support roller 4 on one side of the support roller 4. The driven shaft 15 is connected to the follower shaft 13 by a transmission rod 12 to ensure the effective transmission of power and ensure that the cam 10 only slaps the upper end of the conveyor belt 2.
