Description

Technical Field

[0001] This application relates to the technical field of belt conveyor auxiliary equipment, and in particular to a receiving hopper with adjustable outlet flow. Background Technology

[0002] In bulk cargo transportation scenarios such as mines and docks, belt conveyors are the main means of transporting materials such as ore and coal, and are often used in combination with crushers. The receiving hopper, as a key auxiliary device of the belt conveyor, is usually located below the crusher outlet to receive the material after crushing and guide it to fall onto the belt conveyor.

[0003] In related technologies, belts are usually inclined at a certain angle upwards along the transport direction. Since the size of the discharge port of the traditional receiving hopper cannot be adjusted, the cross-section of the material transported on the belt depends entirely on the crushing output of the crusher. Therefore, material leakage and belt misalignment are prone to occur, and the belt is easily damaged. At the same time, because the material flow rate transported to the belt is unstable, the load on the belt conveyor varies greatly, which seriously affects the stability of the belt conveyor operation. Moreover, this uneven flow phenomenon will continue downstream of the belt conveyor, affecting the entire transport line. Utility Model Content

[0004] In order to reduce material loss and equipment damage caused by uneven material flow during discharge, this application provides a receiving hopper with adjustable outlet flow.

[0005] This application provides a receiving hopper with adjustable outlet flow rate, which adopts the following technical solution:

[0006] A receiving hopper with adjustable outlet flow includes a mounting bracket, a receiving hopper body, and a gate. The mounting bracket is fixedly connected to the receiving hopper body, which is located above a conveyor belt. The receiving hopper body has a discharge port on one side along the conveyor belt direction, and a gate with an adjustable discharge port size is installed at the discharge port.

[0007] By adopting the above technical solution, when the receiving hopper is used in conjunction with the belt conveyor, the mounting bracket fixes the receiving hopper body to the external equipment. The material passes through the receiving hopper body and falls onto the belt of the belt conveyor. The material is transported to the discharge port by the belt. The gate ensures that the material flows out of the discharge port in a uniform flow rate, thereby improving the problems of material leakage and belt deviation caused by unstable material flow and making the belt conveyor run stably.

[0008] Preferably, the gate includes a fixed arm and a blocking arm. There are two fixed arms, which are fixedly installed at both ends of the blocking arm. The fixed arm is provided with connecting holes, and the two connecting holes are perpendicular to the fixed arm in the axial direction.

[0009] By adopting the above technical solution, the fixed arm is fixed on the discharge plate and connected to the blocking arm. The blocking arm blocks the material, ensuring that the cross-sectional size of the material outlet is a fixed value, so that the load on the belt conveyor is basically constant.

[0010] Preferably, the blocking arm is inverted V-shaped.

[0011] By adopting the above technical solution, when the material passes through the gate, the upper part of the material is blocked by the discharge plate and the gate. Since the blocking arm is inverted V-shaped, the shape of the material that finally flows out of the discharge port is similar to the natural accumulation state of the material. This shape makes it less likely for the material to spill or leak during transportation, thus better ensuring the stability of the material flow and the conveying efficiency.

[0012] Preferably, the discharge plate is provided with mounting plates at both ends, and the mounting plates are provided with mounting holes; the receiving hopper is provided with mounting plates at both ends, and the mounting plates are provided with mounting holes; the fixed arm is provided with connecting holes, and the connecting holes and mounting holes are used to pass bolts through to fix the fixed arm.

[0013] By adopting the above technical solution, the gate is fixed by bolts passing through the mounting holes and connection holes and mounted on the mounting plate. The operation is simple and easy to install and adjust.

[0014] Preferably, the mounting holes are provided in multiple ways, and the multiple mounting holes are arranged from top to bottom.

[0015] By adopting the above technical solution, the gate can be installed at different heights of the receiving hopper through the mounting hole, and the installation position of the gate can be adjusted to control the size of the discharge port and thus control the material outlet flow rate.

[0016] Preferably, the inner wall of the receiving hopper is detachably fitted with a wear-resistant liner.

[0017] By adopting the above technical solution, on the one hand, the wear-resistant liner protects the discharge plate, the drop baffle and the inner wall of the side plate, extending the service life of the receiving hopper; on the other hand, the wear-resistant liner also effectively prevents the inertial spillage of materials, reduces the impact of materials on the belt, and extends the service life of the belt.

[0018] Preferably, the lower end of the receiving hopper is equipped with an adjustable height first anti-overflow skirt, the upper end of the first anti-overflow skirt is provided with a first fixing hole, the first fixing hole is used to install the first anti-overflow skirt inside the receiving hopper; there are two first anti-overflow skirts, the two first anti-overflow skirts are respectively installed on both sides of the belt, and the lower end of the first anti-overflow skirt is attached to the upper surface of the belt.

[0019] By adopting the above technical solution, the first anti-overflow skirt is installed at the lower end of the side plate and closely attached to the belt, which can prevent materials from spilling from both sides of the belt conveyor, prevent the spread of dust, and improve the working environment; at the same time, it protects the side of the belt from being worn by material collision, extending the service life of the belt; the height of the first anti-overflow skirt is adjustable to adapt to the belt being at different height positions under different loads, ensuring that the first anti-overflow skirt can be attached to the upper surface of the belt.

[0020] Preferably, the lower end of the receiving hopper is equipped with a second anti-overflow skirt with adjustable height, the second anti-overflow skirt being located at the end of the receiving hopper away from the discharge port; the upper end of the second anti-overflow skirt is provided with a second fixing hole, the second fixing hole being used to install the second anti-overflow skirt inside the receiving hopper; the lower end of the second anti-overflow skirt is attached to the upper surface of the belt.

[0021] By adopting the above technical solution, the second anti-overflow skirt is installed at the lower end of the material drop baffle and is set close to the belt. When the material is dropped or during transportation, the second anti-overflow skirt can prevent the material from sliding down in the opposite direction of transportation, thus preventing the spread of dust. This is both environmentally friendly and reduces the wear and tear on the equipment caused by the sliding material. The height of the second anti-overflow skirt is adjustable to adapt to different belt height positions under different loads, ensuring that the second anti-overflow skirt can be attached to the upper surface of the belt.

[0022] Preferably, both the first and second anti-overflow skirt panels have fixing holes at their upper ends. Both the first and second fixing holes are waist-shaped holes. The length direction of the first fixing hole is parallel to the moving direction of the first anti-overflow skirt panel, and the length direction of the second fixing hole is parallel to the moving direction of the second anti-overflow skirt panel.

[0023] By adopting the above technical solution, the first and second fixing holes are designed as waist-shaped holes, allowing the installation height of the first and second anti-spill skirts to be adjusted. The structure is simple, adaptable to different bandwidths and traffic volumes, and increases operational flexibility.

[0024] Preferably, both the first and second spill-proof skirt panels are made of ultra-high molecular weight polyethylene.

[0025] By adopting the above technical solutions, ultra-high molecular weight polyethylene (UHMWPE) has excellent wear resistance and self-lubrication properties, a long service life, and low density, making it lightweight. The lightweight design reduces transportation and installation costs.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting a gate, which is installed at different heights on the mounting plate, the size of the discharge port can be adjusted to regulate the material outlet flow rate. This effectively solves the problems of belt misalignment, material loss and equipment damage caused by uneven material flow during discharge, and improves the operational stability of the belt conveyor.

[0028] 2. By setting the blocking arm to an inverted V shape, the material passes through the discharge port in a shape similar to the natural accumulation state of the material, making it less likely for the material to slip off. This reduces the phenomenon of material leakage during material transportation and effectively ensures the stability of the material flow and the conveying efficiency.

[0029] 3. By setting wear-resistant liners, the inner wall of the receiving hopper is protected, avoiding wear between the falling material and the receiving hopper body, thus extending the service life of the receiving hopper body; at the same time, it also avoids the material falling directly impacting the belt, reducing the impact force of the material on the belt, reducing belt wear, and extending the service life of the belt.

[0030] 4. By setting adjustable height first and second anti-overflow skirts, materials are prevented from sliding off the sides of the conveyor belt or in the opposite direction of transport, reducing dust diffusion and improving the working environment; at the same time, the sides of the belt are protected from wear and tear by material collisions, extending the belt's service life.

[0037] The following is in conjunction with the appendix Figure 1-5This application will be described in further detail.

[0038] This application discloses a receiving hopper with adjustable outlet flow rate.

[0039] Reference Figure 1 and Figure 2 The system includes a receiving hopper body 1 and a gate 2. The receiving hopper body 1 has a discharge port 3, and the gate 2 is installed at the discharge port 3. The gate 2 is used to control the flow rate of the material after being crushed by the crusher when it flows out of the discharge port 3. When the receiving hopper is used in conjunction with a belt conveyor, the material passes through the receiving hopper body 1 and falls onto the belt 7 of the belt conveyor. The material is transported by the belt 7 to the discharge port 3 and passes through the gate 2. The gate 2 controls the material to flow out of the discharge port 3 at a stable flow rate, thereby reducing material loss and equipment damage, and improving the stability of the belt conveyor operation.

[0040] Reference Figure 1 and Figure 3 The receiving hopper 1 includes a discharge plate 11, a discharge baffle 12, and two side plates 13. The discharge plate 11 is perpendicular to the conveyor belt 7, and the discharge baffle 12 is vertically positioned, with the discharge plate 11 located on the side of the discharge baffle 12 closest to the downstream side of the conveyor belt 7. The two ends of the two side plates 13 are fixedly connected to the sides of the discharge plate 11 and the discharge baffle 12, respectively, forming a vertically continuous hopper cavity 15. The horizontal cross-section of the receiving hopper 1 is rectangular. The discharge plate 11, the discharge baffle 12, and the two side plates 13 are all located above the conveyor belt 7. The discharge port 3 is located at the end of the discharge plate 11 closest to the conveyor belt 7, so that after the material falls onto the conveyor belt 7, it is transported downstream along with the conveyor belt 7 through the discharge port 3.

[0041] Multiple wear-resistant liners 14 are detachably connected to the inner wall of the receiving hopper 1, and the multiple wear-resistant liners 14 are arranged in an array. On the one hand, the wear-resistant liners 14 protect the inner walls of the discharge plate 11, the discharge baffle 12, and the side plates 13, helping to extend the service life of the receiving hopper 1; on the other hand, the wear-resistant liners 14 rub against and collide with the material, slowing down the falling speed of the material, reducing the impact force of the material on the belt conveyor, and extending the service life of the belt 7. In this embodiment, the wear-resistant liners 14 are made of alloy plates, and the alloy plates are bolted to the inner walls of the discharge plate 11, the discharge baffle 12, and the two side plates 13 respectively.

[0042] Reference Figure 2 and Figure 4The gate 2 includes a blocking arm 22 and two fixed arms 21. The blocking arm 22 has an inverted V-shaped structure, and the lower contour of the discharge plate 11 is also inverted V-shaped, corresponding to the inverted V-shaped structure of the blocking arm 22. The two fixed arms 21 are respectively located at both ends of the blocking arm 22, and the blocking arm 22 and the two fixed arms 21 are integrally formed. The end of the fixed arm 21 away from the blocking arm 22 is provided with a connecting hole 211, and the axis of the connecting hole 211 is perpendicular to the fixed arm 21. Mounting plates 111 are respectively provided on both sides of the discharge plate 11, and mounting holes 112 are provided on the mounting plates 111, with the axis of the mounting holes 112 perpendicular to the mounting plates 111. Bolts are used to pass through both the connecting hole 211 and the mounting hole 112 to fix the gate 2 to the mounting plate 111, thereby installing the gate 2 at the discharge port 3.

[0043] When the material passes through the gate 2, the part of the material that is higher than the gate 2 is blocked by the discharge plate 11 and the gate 2, so that the shape of the material flowing out of the discharge port 3 is similar to the natural accumulation state of the material. This shape makes it less likely for the material to spill or leak during transportation, thus better ensuring the stability of the material flow and the conveying efficiency. In addition, the material flow is controlled by mechanical principles, which is simple in structure and easy to operate, saving the installation and use costs of complex equipment.

[0044] Multiple mounting holes 112 are provided, evenly arranged from top to bottom on the mounting plate 111. By fixing bolts into the mounting holes 112 at different heights, the installation height of the gate 2 on the mounting plate 111 can be adjusted, thereby adjusting the size of the discharge port 3 and controlling the material outlet flow rate. When the material passes through the discharge port 3, with a constant belt speed of the belt 7, the material flow rate remains constant, and the load borne by the belt conveyor is also basically constant. This not only makes the belt conveyor operation more stable and improves the service life of the belt conveyor components, but also reduces material loss, making the conveyor transport line more energy-efficient and environmentally friendly.

[0045] Reference Figure 1 and Figure 5 An adjustable-height first anti-overflow skirt 4 is installed at the lower end of the side plate 13. The width of the first anti-overflow skirt 4 is the same as the width of the side plate 13, and the lower end of the first anti-overflow skirt 4 is attached to both sides of the upper surface of the belt 7. The upper end of the first anti-overflow skirt 4 has multiple first fixing holes 41 arranged along the width direction of the first anti-overflow skirt 4. The first anti-overflow skirt 4 is fixed to the inner side of the side plate 13 by bolts passing through the first fixing holes 41. The first anti-overflow skirt 4 can prevent materials from spilling from both sides of the belt 7, reduce dust diffusion, improve the working environment, and protect the sides of the belt 7 from wear and tear caused by material collisions, thus extending the service life of the belt 7.

[0046] The lower contour of the material discharge baffle 12 corresponds to the upper surface contour of the belt 7. An adjustable-height second anti-overflow skirt 5 is installed at the lower end of the material discharge baffle 12. The shape of the second anti-overflow skirt 5 is consistent with the shape of the upper surface of the belt 7, and the lower end of the second anti-overflow skirt 5 is attached to the upper surface of the belt 7. Multiple second fixing holes 51 are provided at the upper end of the second anti-overflow skirt 5, and are arranged along the edge of the upper contour of the second anti-overflow skirt 5. The second anti-overflow skirt 5 is fixed to the inner side of the material discharge baffle 12 by bolts. During material discharge or transportation, the second anti-overflow skirt 5 can prevent material from sliding in the opposite direction of transportation, reducing material waste and wear on the equipment caused by sliding material.

[0047] Both the first fixing hole 41 and the second fixing hole 51 are oblong holes; the length direction of the first fixing hole 41 is parallel to the moving direction of the first anti-overflow skirt 4, and the length direction of the second fixing hole 51 is parallel to the moving direction of the second anti-overflow skirt 5; by adjusting the position of the bolt in the oblong hole, the lower ends of the first anti-overflow skirt 4 and the second anti-overflow skirt 5 can be adjusted to be attached to the upper surface of the belt 7 respectively, so that the first anti-overflow skirt 4 and the second anti-overflow skirt 5 can adapt to different bandwidths and carrying capacities, increasing the flexibility of use.

[0048] In this embodiment, both the first spill-proof skirt plate 4 and the second spill-proof skirt plate 5 are made of ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene has excellent wear resistance and self-lubrication properties, a long service life, and low density, making it lightweight. The lightweight design reduces transportation and installation costs.

[0049] The receiving hopper body 1 is provided with mounting brackets 6 around its perimeter, and the other end of the mounting brackets 6 is used to connect to external equipment. In this embodiment, there are two mounting brackets 6, and the two mounting brackets 6 are respectively fixedly connected to the discharge plate 11 and the discharge baffle 12 by bolts.

[0050] The implementation principle of the adjustable outlet flow receiving hopper disclosed in this application is as follows: the material passes through the hopper cavity 15 of the receiving hopper body 1 and rubs and collides with the wear-resistant liner 14, and then falls onto the belt 7 located in the hopper cavity 15; the first anti-overflow skirt 4 and the second anti-overflow skirt 5 prevent the material from spilling from both sides or rolling and sliding down along the belt 7; when the material moves to the discharge port 3 with the belt 7, the part of the material that accumulates above the gate 2 is blocked by the discharge plate 11 and the blocking arm 22, so that the shape of the material flowing out of the discharge port 3 is approximately the state of natural accumulation of the material, so that the material is transported... The process is less prone to spillage and side leakage, ensuring the stability and efficiency of the material flow, while also maintaining a fixed cross-sectional size at the material outlet, thus keeping the load on the belt conveyor essentially constant. By adjusting the installation height of gate 2, the material outlet flow rate can be controlled to meet the needs of different scenarios. With a constant belt speed, the material outlet flow rate remains unchanged, and the load on the belt conveyor is also essentially constant. This improves the operational stability of the belt conveyor and extends the service life of each component, reducing material loss and making the conveyor transport line more energy-efficient and environmentally friendly.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
