Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor hopper returners, in particular to a belt conveyor hopper returner provided with an impact protection piece. Background Art

[0002] The belt conveyor hopper returner, as an important component of the belt conveyor system, is mainly responsible for accurately and efficiently transporting materials from the hopper to the belt conveyor for subsequent transportation and processing;

[0003] At present, the baffle plate in the belt conveyor hopper is a turtle-back baffle plate, but the impact surface lining of the turtle-back baffle plate is easy to wear, and the easily worn bottom plate is not replaced in time. At the same time, the turtle-back baffle plate uses a special lining plate, which is inconsistent with the conventional lining plate 400*400 or 200*200 size, and needs to be prepared separately. In addition, the base of the back support rod of the turtle-back baffle plate is easily loosened by the impact of the material, causing the baffle plate to move backward, causing the material impact point to move downward, and will impact the hopper wall or cause the material to deviate. In addition, the turtle-back baffle plate is suspended in the hopper with an axis. Due to its large size and heavy weight, it is subject to long-term impact from materials, and there is a safety hazard of falling. In addition, the cost of the turtle-back baffle plate is relatively high.

[0004] Therefore, we proposed a belt conveyor hopper returner equipped with impact protection parts to solve the above problems well. Utility Model Content

[0005] The purpose of the present utility model is to provide a belt conveyor hopper returner provided with an impact protection part, so as to solve the problem proposed in the above-mentioned background technology that the impact surface lining of the turtle-back type material baffle plate is easy to wear, and the easily worn bottom plate is not replaced in time. At the same time, the base of the back support rod of the turtle-back type material baffle plate is easy to be loosened by the impact of the material, causing the material baffle plate to move backward, causing the material impact point to move downward, which will impact the hopper wall or cause the material to deviate.

[0006] To achieve the above object, the utility model provides the following technical solution: a belt conveyor hopper returner provided with an impact protection member, comprising a bracket, the top of which is fixedly connected to a hopper body, and a support plate welded to the lower inner side of the bracket, the upper surface of which is mounted with the belt conveyor body;

[0007] It also includes: three sections of steel grooves are set at equal angles above and below the inner wall of the hopper body, and a protective liner is welded between two three-section steel grooves, rotating rods are set on the left and right sides of the hopper body, and a transmission rod is connected to the front of the hopper body;

[0008] The outside of the hopper body is connected to a fixed frame with bolts at equal intervals, and the inside of the fixed frame is connected with a striking block, a return spring is installed at the connection position between the outside of the striking block and the fixed frame, and cams are installed at equal intervals on the outside of the transmission rod and the two rotating rods.

[0009] Preferably, the hopper body is arranged above the support plate, and vertical plates are installed on both sides of the support plate.

[0010] Preferably, the protective liner is arranged at an angle on the inner wall of the hopper body, and the three sections of steel trough are welded to the inner wall of the bracket.

[0011] Preferably, the shaft end of the belt conveyor body is connected to the outer side of the right side of the transmission rod through a pulley assembly, and the transmission rod is rotatably connected to the front side of the hopper body.

[0012] Preferably, both ends of the transmission rod and one end of the two rotating rods are connected to each other through a bevel gear set, and the bevel gear sets are meshed with each other.

[0013] Preferably, the striking block is slidably connected to the fixed frame, and the striking block is arranged in a "T" shape.

[0014] Preferably, the striking block forms a reciprocating telescopic structure through a return spring and a cam, the positions of the cam and the striking block correspond one to one, and the end of the striking block fits with the outer side of the cam.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the belt conveyor hopper returner provided with an impact protection member adopts a new structural design, the specific contents of which are as follows:

[0016] (1) A returner is made by reinforcing and welding three sections of steel troughs, which can ensure the firmness of the protective liner installed in the hopper body to prevent it from falling, and form a material surface above the returner to withstand the impact of the material, greatly reducing the need to replace the protective liner. At the same time, a protective liner is set on the inner wall of the hopper body to protect the hopper body and prevent the hopper body from being offset by the material, which may cause the material to deviate;

[0017] (2) When the material falls from the hopper body to the belt conveyor body, the vertical plates arranged on both sides of the belt conveyor body are used to make the material fall accurately onto the belt conveyor body, and the material is transported to the designated location through the belt conveyor body;

[0018] (3) When the belt conveyor body is running, the pulley assembly is used to drive the transmission rod to rotate synchronously. At the same time, the transmission rod uses two bevel gear sets to drive the two rotating rods to rotate. At this time, the multiple cams on the transmission rod and the two rotating rods rotate and reciprocate to squeeze the striking block, causing it to move and knock on the outside of the hopper body, causing vibration in the hopper body, so that the material slides smoothly onto the belt conveyor body, preventing the material from being blocked in the hopper body;

[0019] Furthermore, when the cam does not squeeze the striking block, the striking block is reset under the elastic force of the reset spring, and the above operation is repeated, thereby causing the squeezing block to strike the outer side of the hopper body back and forth.

[0030] It also includes: three sections of steel grooves 6 are arranged at equal angles above and below the inner wall of the hopper body 2, and a protective liner 7 is welded between two three-section steel grooves 6, the protective liner 7 is arranged obliquely on the inner wall of the hopper body 2, and the three sections of steel grooves 6 are welded to the inner wall of the bracket 1;

[0031] The material is added into the hopper body 2. At this time, a returner is made by reinforcing and welding three sections of steel troughs 6, which can ensure the firmness of the installation of the protective liner 7 in the hopper body 2 to prevent it from falling, and form a material surface above the returner to withstand the impact of the material, greatly reducing the need to replace the protective liner 7. At the same time, a protective liner 7 is set on the inner wall of the hopper body 2 to protect the hopper body 2 and prevent the hopper body 2 from being offset by the material, which causes the material to deviate. Then the material in the hopper body 2 falls onto the belt conveyor body 4, and the belt conveyor body 4 is started, and the belt conveyor body 4 transports the material to the designated position.

[0032] Embodiment 2: Different from embodiment 1, this embodiment uses the vertical plate 5 to make the material fall accurately onto the belt conveyor body 4 to prevent deviation. Figure 1 and Figure 5 As shown, the hopper body 2 is arranged above the support plate 3, and vertical plates 5 are installed on both sides of the support plate 3;

[0033] When the material falls from the hopper body 2 onto the belt conveyor body 4, the vertical plates 5 provided on both sides of the belt conveyor body 4 are used to ensure that the material falls accurately onto the belt conveyor body 4 to prevent deviation.

[0034] Example 3: Different from Example 2, this embodiment uses the striking block 13 to strike the outer side of the hopper body 2 back and forth, so that the hopper body 2 generates vibration, thereby allowing the material to slide smoothly onto the belt conveyor body 4, preventing the material from being blocked in the hopper body 2. For details, refer to Figure 1-Figure 3 and Figure 6As shown, rotating rods 11 are provided on the left and right sides of the hopper body 2, and a transmission rod 9 is connected to the front of the hopper body 2. The shaft end of the belt conveyor body 4 is connected to the outer side of the right side of the transmission rod 9 through a pulley assembly. The transmission rod 9 is rotatably connected to the front of the hopper body 2, and the two ends of the transmission rod 9 are connected to one end of the two rotating rods 11 through a bevel gear set, and the bevel gear sets are meshed; the outer side of the hopper body 2 is evenly spaced with bolts connected to a fixed frame 8, and the interior of the fixed frame 8 is penetrated by a striking block 13, and a return spring 12 is installed at the connection position between the outer side of the striking block 13 and the fixed frame 8. Cams 10 are evenly spaced and sleeved on the outer sides of the transmission rod 9 and the two rotating rods 11. The striking block 13 is slidably connected to the fixed frame 8, and the striking block 13 is arranged in a "T" shape. The striking block 13 forms a reciprocating telescopic structure through the return spring 12 and the cam 10. The positions of the cam 10 and the striking block 13 correspond one to one, and the end of the striking block 13 fits in with the outer side of the cam 10.

[0035] When the belt conveyor body 4 is running, the pulley assembly is used to drive the transmission rod 9 to rotate synchronously. At the same time, the transmission rod 9 uses two bevel gear sets to drive the two rotating rods 11 to rotate. At this time, the multiple cams 10 on the transmission rod 9 and the two rotating rods 11 rotate, and reciprocally squeeze the striking block 13, causing it to move (at this time the return spring 12 is in a stretched state), and knock on the outside of the hopper body 2, causing vibration in the hopper body 2. When the cam 10 does not squeeze the striking block 13, the striking block 13 is reset under the elastic force of the return spring 12, and the above operation is repeated, so that the striking block 13 reciprocates and knocks on the outside of the hopper body 2, so that the material slides smoothly onto the belt conveyor, preventing the material from being blocked in the hopper body 2.
