Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor material guiding technology, and in particular relates to a belt conveyor material guiding trough device. Background Technology

[0002] Belt conveyors are a common type of conveyor used in industry for transporting materials. They have a wide range of applications, capable of transporting various types of materials, including crushed and lumpy materials, over both long and short distances. Belt conveyors are used in industries such as metallurgy, mining, and transportation.

[0003] Belt conveyors transport materials via belts. During production, to facilitate material feeding onto the belt, a guide chute structure is often fixedly installed on the conveyor frame. This guide chute structure not only guides the material feeding but also helps suppress dust dispersion during the feeding process.

[0004] like Figure 1 As shown, the main structure of the existing material guide trough structure mostly includes a material guide trough support, which is fixedly mounted on the conveyor frame by a mounting bracket 11 fixed to its side. To guide the material to the center of the belt during the feeding process and prevent material spillage from the sides, a material guide plate 1 is usually installed at the bottom of the material guide trough support. However, the material guide plates 1 in the existing technology are mostly fixedly installed, and in most cases, a fixedly installed guide plate can smoothly guide the material to the center of the belt.

[0005] However, the drawbacks are also obvious: for example, when the material feeding speed is very fast and the feeding volume is large, because the guide plate 1 of this fixed-connection guide chute cannot be adjusted, it is impossible to further "push" the material towards the center. As a result, the material easily slips off the belt from the edge of the guide plate 1. Secondly, due to its non-adjustability, the feeding cannot be adjusted according to the state of the material. For example, for crushed gangue, if the guide plates are too close together, although it can ensure that the material does not slip off the edge of the belt, the material feeding resistance is large because the guide plates 1 of the guide chute are too close together.

[0006] Meanwhile, in order to ensure that materials do not spill from the edge of the belt during the feeding process, existing technologies often install skirt plates on both sides of the guide chute. The skirt plates support the bottom edge of the belt and lift the belt up. However, the skirt plates and the belt are in a sliding friction manner, which causes severe wear on the edge of the belt. After wear, as the belt's service life increases, cracks begin to appear on the edge of the belt, and the belt may even tear apart from the edge. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a belt conveyor guide trough device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A belt conveyor guide trough device includes a guide trough support, and guide plates are installed on both sides of the bottom of the guide trough support. The guide plates are respectively hinged by a flip adjustment structure.

[0010] The flipping adjustment structure includes a fixed hinge bracket fixedly installed on the side wall of the guide trough, and also includes a number of hinge teeth fixedly connected to the guide plate; the hinge teeth are hinged to the fixed hinge bracket.

[0011] The guide plate is flipped by several hinged push structures.

[0012] Preferably, the top of the feed trough support is connected to a feed inlet;

[0013] The guide trough support is fixedly mounted on the frame of the belt conveyor on both sides by several mounting brackets.

[0014] Preferably, the longitudinal cross-sectional shape of the fixed hinge bracket is L-shaped; the bottom of the fixed hinge bracket is provided with a plurality of hinge slots;

[0015] The hinge tooth is hinged in the hinge slot, and a long pin shaft that passes through the hinge tooth is fixedly connected to the fixed hinge bracket. The hinge tooth is hinged and installed on the long pin shaft.

[0016] Preferably, a pushing structure is installed on both sides of the inner wall of the guide plate.

[0017] Preferably, the pushing structure includes an electric push rod, and the pushing end of the electric push rod is fixedly connected to a hinge sleeve;

[0018] A hinge seat is fixedly connected to the guide plate, and a pin is fixedly connected to the hinge seat. The hinge sleeve is hinged to the pin.

[0019] The top of the electric push rod is fixedly connected to an ear seat, the ear seat is hinged to a suspension bracket, and the suspension bracket is fixedly connected to a pin that hinges the ear seat.

[0020] The suspension bracket is suspended at the bottom of the feed chute bracket by mounting screws.

[0021] Preferably, the lower end of the guide plate is provided with an installation groove, and a rubber plate is installed in the installation groove.

[0022] Preferably, a skirt mechanism is installed on both sides of the feed trough support;

[0023] The skirt mechanism is supported at the bottom edge of the belt.

[0024] Preferably, the skirt mechanism includes a skirt bracket fixedly installed on the outside of the hinge bracket;

[0025] A skirt plate that is inclined downwards is fixedly installed at the lower end of the skirt bracket;

[0026] The lower end of the skirt plate is supported on the bottom edge of the belt by a rolling structure.

[0027] Preferably, the rolling structure includes a roller groove formed at the lower end of the top of the skirt plate;

[0028] The rotating roller groove is rotatably connected to several rotating rollers distributed along the length of the rotating roller groove.

[0029] Preferably, the two ends of the roller are fixedly connected to a rotating shaft, which is rotatably connected to the roller groove.

[0030] This utility model has the following beneficial effects:

[0031] 1. This utility model improves the guide plate to ensure that, during operation, when feeding powdered materials at high speeds and in large quantities, the material falls fully into the center of the conveyor belt, preventing it from overshooting the guide plate and slipping off the belt. By activating the electric push rod, the guide plates on both sides gradually open and decrease in width, allowing the material to fall onto the conveyor belt through the guide plates. This method ensures that even with rapid material feeding, the material is smoothly guided and falls into the center of the conveyor belt.

[0032] 2. When feeding lumpy materials (lumpy materials have poor flowability and are not easy to overturn and spill from the edge of the conveyor belt), in order to ensure sufficient material flow, the guide plate is opened wider by the electric push rod. This speeds up the feeding process, and the increased opening of the guide plate makes the impact of the material more moderate, thus assisting in the feeding process while protecting the guide plate.

[0033] 3. This utility model improves the skirt plate to reduce wear on the belt edge. Specifically, it uses a rolling and sliding structure to support the raised edge of the belt while protecting the belt through rolling friction, thus reducing wear on the belt edge. When the belt edge is supported on the rotating roller, the belt edge is also raised under the support of the roller, and the roller rotates under friction, thereby protecting the belt.

[0045] Example 1

[0046] like Figure 1-6 As shown, a material guide trough device for a belt conveyor includes a material guide trough support 2. The material guide trough support 2 is a conventionally disclosed support for a material guide trough on an existing belt conveyor. It is fixedly installed on the frame of the belt conveyor by a number of mounting brackets (not shown in the figure) on the left and right sides of the material guide trough support 2.

[0047] Meanwhile, similar to the existing feeding method of the guide chute, a feeding port 21 is connected to the top of the guide chute support 2, and the material is fed from the feeding port 21.

[0048] In order to enable adjustable guiding and feeding based on the feeding speed, feeding amount, and material state (such as powder or lumps) during the feeding process, this utility model makes the following improvements to the existing guide chute structure:

[0049] The bottom left and right sides of the guide trough bracket 2 are equipped with mutually cooperating guide plates 4, which are respectively hinged by a flip adjustment structure.

[0050] Specifically, the flipping adjustment structure includes a fixed hinge bracket 41 (the longitudinal cross-sectional shape of the fixed hinge bracket 41 is L-shaped) fixedly installed on the side wall of the guide trough, and also includes a number of hinge teeth 53 fixedly connected to the guide plate 4; the hinge teeth 53 are hinged to the fixed hinge bracket 41.

[0051] The specific hinge method is as follows: the bottom of the fixed hinge bracket 41 is provided with several hinge slots; the hinge teeth 53 are hinged in the hinge slots, and a long pin shaft that passes through the hinge teeth 53 is fixedly connected to the fixed hinge bracket 41, and the hinge teeth 53 are hinged on the long pin shaft.

[0052] The stability of the hinged flipping is increased by setting the hinge teeth 53 along the length direction of the top of the guide plate 4. At the same time, in order to enable the guide plate 4 to flip, the inner sidewall of each guide plate 4 is pushed to flip by a pair of front and rear spaced, hinged push structures.

[0053] Specifically, the pushing structure includes an electric push rod 5, and the pushing end of the electric push rod 5 (the electric push rod 5 is a conventional electric telescopic rod disclosed in the prior art, and the pushing end is the telescopic rod end position of the electric telescopic rod) is fixedly connected to a hinge sleeve.

[0054] Correspondingly, a hinge seat 51 is fixedly connected to the guide plate 4, and a pin is fixedly connected to the hinge seat 51, with the hinge sleeve hinged to the pin.

[0055] Meanwhile, the top of the electric push rod 5 is fixedly connected to an ear seat, and the ear seat is hinged to a suspension bracket 52 (an L-shaped bracket), and the suspension bracket 52 is fixedly connected to a pin of the hinged ear seat; the suspension bracket is suspended at the bottom of the guide trough bracket 2 by a mounting screw 521.

[0056] During operation, when feeding powdery materials at high speeds and in large quantities, to ensure that the material falls fully into the center of the conveyor belt and prevents it from overshooting the guide plates 4 and slipping off the belt from the edge, the electric push rod 5 is activated. With the pull of the electric push rod 5, the guide plates 4 on both sides gradually open and decrease in width, allowing the material to fall from the guide plates 4 onto the conveyor belt.

[0057] This method ensures that the material can be smoothly guided and fall into the center of the conveyor belt when the material is fed too quickly.

[0058] When the material is in block form (block material has poor flowability and is not easy to overturn and spill from the edge of the conveyor belt), in order to ensure sufficient material flow, the guide plate 4 is opened wider by the electric push rod 5. This speeds up the material flow and, because the guide plate 4 is opened wider, the impact of the material is more mitigated, thus assisting in the material flow while protecting the guide plate 4.

[0059] In actual operation, the guide plate 4 is made of a rigid and lightweight material, such as aluminum alloy steel plate, in accordance with the existing method.

[0060] Example 2

[0061] like Figure 1-6 As shown, in this embodiment, based on the structure of Embodiment 1, in order to reduce wear between the guide plate 4 and the belt and protect the belt, an installation groove is provided at the lower end (specifically at the bottom position) of the guide plate 4, and a rubber plate 6 is installed in the installation groove. The rubber plate 6 is fastened by bolts. The flexibility of the rubber plate protects the belt after contact with it.

[0062] Example 3

[0063] like Figure 1-6As shown, in this embodiment, based on the structure of embodiment 2, in order to ensure that the edge of the belt is in a raised state and reduce the material spillage from the edge, in the same way as the existing method, a skirt mechanism is installed on the left and right sides of the guide trough bracket 2.

[0064] Specifically, the skirt mechanism is supported at the bottom edge of the belt. In particular, the skirt mechanism includes a skirt bracket 3 fixedly installed on the outside of the fixed hinge bracket 41; the skirt bracket 3 is fastened to the guide trough bracket 2 by bolts (the bolts pass through the fixed hinge bracket 41, thus fixing the fixed hinge bracket 41).

[0065] Meanwhile, a downwardly inclined skirt plate 31 is fixedly installed at the lower end of the skirt bracket 3; the lower end of the skirt plate 31 is supported on the bottom edge of the belt by a rolling structure. The skirt plate 31 supports the edge of the belt, thereby causing the edge of the belt to curl upward.

[0066] However, since the belt is in a transmission state, the skirt plate 31 and the belt are always in a state of friction. Therefore, as the service life of the belt conveyor increases, the wear increases and cracks or even breaks easily appear at the edge of the belt (during the material transmission process, the belt needs to work under a high tension, so while wear increases, it is more easily damaged).

[0067] Therefore, this utility model improves the skirt plate 31 in order to both maintain the edge of the belt curling up and protect the edge of the belt.

[0068] Specifically, the rolling structure supports the raised edge of the belt while protecting the belt through rolling friction, thus reducing wear on the belt edge.

[0069] Specifically, the rolling structure includes a roller groove located at the lower end of the top of the skirt plate 31; several rollers 7 are rotatably connected inside the roller groove and distributed along the length of the roller groove.

[0070] When the edge of the belt is supported on the rotating roller 7, the edge of the belt also lifts up under the support of the rotating roller 7, and the rotating roller 7 rotates under the action of friction, thus protecting the belt.

[0071] According to the existing roller rotation connection method, the two ends of the aforementioned roller 7 are respectively fixedly connected to rotating shafts, which are rotatably connected to the grooves of the roller 7. Specifically, mounting holes that mate with the rotating shafts are opened on the inner groove side of the roller 7 groove, and bearings are installed in the mounting holes. At the same time, bearing brackets are installed on the outer groove side of the roller 7 groove, and the outer rotating shaft is rotatably connected to the bearing brackets, so as to make the rotation of the roller 7 more flexible.

[0072] This method enhances the protection of the belt edges.

[0073] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
