Description

Technical Field

[0001] This utility model relates to the field of material transfer equipment technology, and more specifically, to a material conveying hopper for a conveyor. Background Technology

[0002] Receiving hoppers are widely used in industries such as power, coal, chemical, building materials, and ports. Their function is to guide materials unloaded from the upper belt conveyor into subsequent equipment, silos, or lower conveyors for transport.

[0003] Patent authorization number CN210365753U discloses a receiving hopper for a belt conveyor, including a hopper, a feeding mechanism, and a spiral auger. The bottom of the hopper is connected to a first connecting pipe; a first annular groove is opened on the circumferential side of one end of the first connecting pipe; the feeding mechanism includes a second connecting pipe; a second annular groove is opened on the circumferential side of one end of the second connecting pipe; the other end of the second connecting pipe is connected to a bent pipe; one end of the bent pipe is connected to a material distribution hood; material distribution plates are arrayed inside the material distribution hood; a connecting rod is provided on the circumferential side of the spiral auger; a sleeve is fixed to one end of the connecting rod; toothed grooves are opened on the circumferential side of the sleeve. The spiral auger is driven by a servo motor to transport the material in the hopper to the belt, reducing material spillage and dust, reducing belt wear, and the material distribution plates evenly distribute the transported material, preventing uneven distribution of material on the belt and causing belt deviation, thus improving production efficiency.

[0004] However, in the patent authorization number CN210365753U, after the material enters the inner side of the funnel, the uneven particle size of the material can easily cause blockage of the connecting pipe. Forcing the material to flow through the auger can not only damage the auger and the connecting pipe, but also cause the motor to burn out if the auger gets stuck, thus affecting the normal material flow. Therefore, we have proposed a material conveying funnel for a conveyor to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a material conveying hopper for a conveyor. By screening out large-diameter particles in the material, it can effectively prevent large-diameter materials from clogging the bottom opening of the hopper body, thereby preventing the spiral blades from getting stuck and the geared motor from burning out. Through the synchronous rotation of the spiral blades, the material entering the bottom opening of the hopper body is unblocked downwards, preventing material blockage and ensuring normal material discharge from the hopper body.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A conveyor hopper includes a hopper body and a support for supporting the hopper body. A screen plate is installed at an angle on the inner side of the hopper body, and the end of the screen plate extends to the outer side of the hopper body.

[0010] A guide plate is installed above the sieve plate;

[0011] The outer side wall of the funnel body is symmetrically fixedly connected with guide bosses. The top of the bracket is provided with a guide hole that is slidably connected to the guide bosses. The bottom wall of the guide hole is equipped with a spring connected to the guide bosses. A vibration motor is installed on the guide bosses through a fixing frame.

[0012] A support frame is welded below the sieve plate. A rotating shaft extending to the bottom opening of the funnel body is rotatably connected to the support frame via a bearing. A spiral blade is welded to the bottom end of the rotating shaft. A protective cover is installed on the support frame corresponding to the lower surface of the rotating shaft. A driven bevel gear located inside the protective cover is installed at the top of the rotating shaft.

[0013] A geared motor is installed on the outside of the funnel body. The power output end of the geared motor is connected to a transmission shaft that passes through the funnel body and extends to the inside of the protective cover via a coupling. The end of the transmission shaft is equipped with a driving bevel gear that meshes with the driven bevel gear.

[0014] Furthermore, the funnel body has a discharge port on the side wall corresponding to the end of the sieve plate.

[0015] Furthermore, the guide plate is angled, and the end of the guide plate is inclined toward the end of the screen plate.

[0016] Furthermore, the outer diameter of the spiral blade is adapted to the inner diameter of the bottom opening of the funnel body.

[0017] Furthermore, dynamic seals are installed at the joints between the protective cover and the rotating shaft and the transmission shaft.

[0018] Furthermore, the outer wall of the funnel body is welded with a mounting base for mounting the geared motor.

[0019] Furthermore, the drive shaft passes through the mounting base, and a bearing is installed at the junction of the mounting base and the drive shaft.

[0020] 3. Beneficial effects

[0021] Compared with existing technologies, the advantages of this utility model are:

[0022] (1) In this solution, the material is added to the inside of the funnel body and the vibration motor is turned on at the same time. The material is guided to the highest point of the screen plate by the guide plate. Then, under the elastic force of the spring, the guide boss and the guide hole set at the top of the bracket jump up and down, thereby driving the funnel body to vibrate. Large-diameter material is intercepted by the screen plate and discharged from the funnel body by its own angle, while qualified material falls through the screen holes on the screen plate. This can effectively prevent large-diameter material from causing blockage at the bottom of the funnel body, thereby preventing the spiral blades from being stuck and preventing the geared motor from burning out.

[0023] (2) In this scheme, the transmission shaft is driven to rotate by a speed reduction motor. The active bevel gear meshes with the driven bevel gear, thereby driving the rotating shaft to rotate in conjunction with the support frame, which in turn drives the spiral blades to rotate synchronously. This allows the material entering the bottom of the funnel body to be cleared downwards, preventing material blockage and ensuring normal material discharge from the funnel body.

[0024] (3) In this solution, the active bevel gear and the driven bevel gear are protected by a protective cover to prevent dust in the material from adhering to the active bevel gear and the driven bevel gear, thereby preventing wear between the active bevel gear and the driven bevel gear and ensuring the accuracy of the transmission between them.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Example:

[0034] Please see Figure 1-5 A conveyor hopper includes a hopper body 1 and a support 2 for supporting the hopper body 1. A screen plate 3 is installed at an angle on the inner side of the hopper body 1, and the end of the screen plate 3 extends to the outer side of the hopper body 1.

[0035] A guide plate 4 is installed above the sieve plate 3;

[0036] The outer side wall of the funnel body 1 is symmetrically fixedly connected with guide bosses 5. The top of the support 2 is provided with a guide hole 6 that is slidably connected to the guide bosses 5. The bottom wall of the guide hole 6 is equipped with a spring 7 that is connected to the guide bosses 5. A vibration motor 8 is installed on the guide bosses 5 through a fixing frame.

[0037] A support frame 11 is welded below the sieve plate 3. A rotating shaft 12 extending to the bottom opening of the funnel body 1 is rotatably connected to the support frame 11 via a bearing. A spiral blade 13 is welded to the bottom of the rotating shaft 12. A protective cover 14 is installed on the lower surface of the support frame 11 corresponding to the rotating shaft 12. A driven bevel gear 15 located inside the protective cover 14 is installed at the top of the rotating shaft 12.

[0038] A geared motor 10 is installed on the outside of the funnel body 1. The power output end of the geared motor 10 is connected to a drive shaft 16 that passes through the funnel body 1 and extends to the inside of the protective cover 14 via a coupling. The end of the drive shaft 16 is connected to a drive bevel gear 17 that meshes with the driven bevel gear 15.

[0039] It should be noted that when the conveyor's material hopper is in use, the material is added to the inside of the hopper body 1, and the vibration motor 8 is turned on. The material is guided to the highest point of the screen plate 3 by the guide plate 4. Then, under the elastic force of the spring 7, the guide boss 5 moves up and down in conjunction with the guide hole 6 set at the top of the bracket 2, thereby driving the hopper body 1 to vibrate. Large-diameter materials are intercepted by the screen plate 3 and discharged from the hopper body 1 by their own angle, while materials with qualified particle size fall through the screen holes on the screen plate 3. This can effectively prevent large-diameter materials from causing blockage at the bottom of the hopper body 1.

[0040] By turning on the geared motor 10 to drive the transmission shaft 16 to rotate, the active bevel gear 17 meshes with the driven bevel gear 15, thereby driving the rotating shaft 12 to rotate in conjunction with the support frame 11, which in turn drives the spiral blades 13 to rotate synchronously, thus clearing the material entering the bottom opening of the funnel body 1 downwards, preventing material blockage, and ensuring normal material discharge from the funnel body 1.

[0041] By using the protective cover 14 to protect the driving bevel gear 17 and the driven bevel gear 15, dust in the material is prevented from adhering to the driving bevel gear 17 and the driven bevel gear 15, thereby preventing wear between the driving bevel gear 17 and the driven bevel gear 15 and ensuring the accuracy of the transmission between them.

[0042] like Figure 1 As shown, the funnel body 1 has a discharge port on the side wall corresponding to the end of the sieve plate 3;

[0043] It should be noted that large-particle materials are intercepted by the sieve plate 3 and discharged from the funnel body 1 through the discharge port using their own angle.

[0044] like Figure 4 As shown, the guide plate 4 is set at an angle, and the end of the guide plate 4 is inclined toward the end of the screen plate 3.

[0045] It should be noted that the guide plate 4 facilitates the full screening of materials using the sieve plate 3.

[0046] like Figure 4 As shown, the outer diameter of the spiral blade 13 is matched with the inner diameter of the bottom opening of the funnel body 1;

[0047] It should be noted that this facilitates the downward flow of material entering the bottom opening of the funnel body 1, preventing material blockage.

[0048] like Figure 5 As shown, dynamic seals are installed at the joints between the protective cover 14 and the rotating shaft 12 and the transmission shaft 16.

[0049] It should be noted that the sealing effect of the protective cover 14 itself is guaranteed.

[0050] like Figure 4 As shown, the outer wall of the funnel body 1 is welded with a mounting base 9 for mounting the geared motor 10, the transmission shaft 16 passes through the mounting base 9, and a bearing is installed at the part where the mounting base 9 and the transmission shaft 16 are combined.

[0051] It should be noted that this reduces the resistance during the rotation of the drive shaft 16 and ensures the rotational accuracy of the drive shaft 16.

[0052] In use: By adding material to the inside of the funnel body 1 and turning on the vibration motor 8, the material is guided to the highest point of the screen plate 3 by the guide plate 4. Then, under the elastic force of the spring 7, the guide boss 5 moves up and down in conjunction with the guide hole 6 set at the top of the bracket 2, thereby driving the funnel body 1 to vibrate. Large-diameter materials are intercepted by the screen plate 3 and discharged from the funnel body 1 by their own angle, while materials with qualified particle size fall through the screen holes on the screen plate 3. This can effectively prevent large-diameter materials from causing blockage at the bottom of the funnel body 1.

[0053] By turning on the geared motor 10 to drive the transmission shaft 16 to rotate, the active bevel gear 17 meshes with the driven bevel gear 15, thereby driving the rotating shaft 12 to rotate in conjunction with the support frame 11, which in turn drives the spiral blades 13 to rotate synchronously, thus clearing the material entering the bottom opening of the funnel body 1 downwards, preventing material blockage, and ensuring normal material discharge from the funnel body 1.

[0054] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
