Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, specifically relating to a belt conveyor tail and a belt conveyor including the aforementioned tail. Background Technology

[0002] Belt conveyors are an important type of conveying equipment in the bulk grain conveying industry. They can be arranged in various ways, such as horizontally or at an incline. The main principle is that a flexible belt is connected into a loop and runs around the head pulley and the tail pulley. The head pulley provides power for the belt's circular motion through the friction between it and the belt. The material enters the equipment near the tail end and falls onto the upper belt, then moves towards the head end with the upper belt. It is then unloaded at the head pulley, thus completing the material conveying process.

[0003] The existing structure is usually a fixed section on the inside connected to the middle section of the equipment, and a movable section on the outside connected to the tail pulley, with a sliding tensioning tail pulley. Because the belt itself is elastic, the belt needs to be tensioned after a period of use. The gap between the movable section and the fixed section is connected with felt or rubber. If it rains for a long time, rainwater will seep into the inside of the shell from the sealing material, causing problems such as dust accumulation and hardening of the shell, and mold growth of residual materials. This problem is more serious when the conveying equipment is arranged at an angle. Utility Model Content

[0004] The first objective of this invention is to provide a belt conveyor tail section to solve the technical problem of water leakage between the outer movable section and the inner fixed section of the existing belt conveyor tail section.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a belt conveyor tail, characterized in that it includes:

[0006] Fixed section, used to connect with intermediate section;

[0007] The movable section has one end fitted inside the fixed section and the other end connected to the tail section.

[0008] A tensioning mechanism is provided on the fixed section and the movable section for tensioning the tail wheel of the tail section.

[0009] This invention places the fixed section connected to the middle section on the outside and the movable section connected to the tail section on the inside, effectively solving the problem of water leakage in the sleeve of the tail tensioning section of the conveyor equipment.

[0010] To solve the technical problems of the tensioning mechanism, this utility model adopts the following technical solution, wherein the tensioning mechanism includes:

[0011] A first mounting base is disposed on the fixed section;

[0012] A second mounting base is provided on the movable section;

[0013] The tensioning assembly is mounted on the first mounting base and the second mounting base. This invention utilizes the tensioning assembly to adjust the depth of the movable section within the fixed section, thereby tensioning the tail pulley. This method is convenient to operate and ensures the stability of the belt tension.

[0014] To address the issues related to how the tensioning assembly is implemented, this invention adopts the following technical solution: the tensioning assembly includes a tensioning screw and a tensioning nut. The tensioning screw passes sequentially through a first mounting base and a second mounting base, and the tensioning screws on both sides of the first and second mounting bases are locked in place by tensioning nuts. This invention effectively ensures the stability of the belt tension by utilizing the tensioning screw and tensioning nut.

[0015] To address the problem of accidental disengagement of the tensioning screw and the extreme difficulty of resetting it, this invention employs the following technical solution: limiting components are provided at both ends of the tensioning assembly to prevent it from detaching from the first and second mounting seats. By providing limiting components at the ends of each tensioning assembly, the problem of accidental disengagement of the tensioning screw and the extreme difficulty of resetting it is effectively prevented, thus reducing the need for limit sensors and lowering equipment costs.

[0016] To address the technical problem of how to implement the tensioning component, this utility model adopts the following technical solution, wherein the tensioning component includes:

[0017] A limiting plate, which is sleeved on the corresponding end of the tensioning screw;

[0018] A limiting pin is radially positioned at the corresponding end of the tensioning screw and located outside the limiting plate. The limiting plate and limiting pin effectively prevent the screw from falling off during tension adjustment, ensuring convenient operation and safe grain transport.

[0019] To solve the technical problem of instability in the tensioning mechanism, the present invention adopts the following technical solution: the tensioning mechanism is provided on both sides of the fixed section and the movable end, and two tensioning mechanisms are arranged vertically on each side.

[0020] To address the problems of jamming and tensioning difficulties caused by large deformation during manufacturing of the inner and outer sleeves in existing belt conveyors, this invention adopts the following technical solution: the top plates of the fixed section and the movable section are in a "V" shape. This invention utilizes the "V" shaped top plate to effectively control plate surface deformation, reducing the problems of tensioning jamming and adjustment difficulties caused by deformation during manufacturing of the inner and outer sleeves.

[0021] To address the technical problem of belt snagging caused by a height difference between the movable section's bottom plate and the fixed section's bottom plate, where the movable section is located on the inside and the fixed section's bottom plate is higher, this invention employs the following technical solution: a liner is installed on the fixed section's bottom plate, with chamfered ends, and the liner's height is higher than the movable section's bottom plate. This liner eliminates the risk of belt snagging caused by this height difference.

[0022] To solve the technical problem of difficult maintenance of fixed sections, this utility model adopts the following technical solution: an inspection port is provided on the fixed section, and an inspection door is provided on the inspection port through a connector, which is convenient for disassembly and assembly and easy for maintenance.

[0023] To solve the technical problem that the distance between the movable segment and the fixed segment cannot be known, this utility model adopts the following technical solution: a limiting component is provided on the fixed segment to limit the maximum distance between the movable segment and the fixed segment, and the minimum distance between the movable segment and the fixed segment can be limited.

[0024] The second objective of this utility model is to provide a belt conveyor, characterized in that it includes:

[0025] The tail of the belt conveyor as described in any of the above items;

[0026] The middle section is connected to the fixed section;

[0027] The discharge port section of the machine head is connected to the intermediate section. Attached Figure Description

[0041] Example 1

[0042] like Figure 1-6 As shown, the tail section 10 of the belt conveyor includes a fixed section 100, a movable section 200, and a tensioning mechanism 300.

[0043] The fixed section 100 is used to connect with the intermediate section. The fixed section 100 includes a top plate 101, two side plates 102, and a bottom plate 103. In one embodiment, the top plate 101 of the fixed section is in the shape of an "A".

[0044] In one embodiment, an access port 107 is provided on the fixed section 100, and an access door 105 is installed on the access port 107. The access door 105 is fixed to the access port 107 via a connector 106. The connector 106 is preferably a bolt and nut. Preferably, access doors 105 are installed on both sides of the fixed section housing. A handle 108 is installed on the access door 105.

[0045] One end of the movable section 200 is fitted inside the fixed section 100, and the other end of the movable section 200 is connected to the tail section 400. This utility model adopts a structural design in which the fixed section connected to the middle section is on the outside and the movable section connected to the tail section is on the inside, effectively eliminating the risk of water seepage into the equipment when the equipment is tilted.

[0046] The movable section 200 includes a top plate 201, two side plates 202, and a bottom plate 203. The top plate 201 is in the shape of an "A". The top of both the fixed section and the movable section adopts an "A" shape, which not only facilitates the smooth flow of rainwater into both sides, but also enhances the strength of the sleeve and prevents problems such as uneven sliding between the sleeves caused by large deformation.

[0047] The movable section is located on the inside, and its bottom plate is higher than the fixed section's bottom plate along the belt's running direction, causing belt scuffing. To solve this problem, in one embodiment, a liner 104 is installed on the fixed section's bottom plate 103. Preferably, the liner 104 has chamfered edges 1040 at both ends. The height of the movable section's bottom plate 203 is lower than the height of the liner 104. A polymer bottom liner is provided on the fixed section's bottom plate, with chamfered edges at both ends. The bottom liner is 3mm higher than the movable section's bottom plate, eliminating the risk of belt scuffing caused by this height difference.

[0048] In one embodiment, support wheels 401 are mounted on the base plate of the tail section 400. Support wheels 204 are mounted on the base plate of the movable section 200. Utilizing two sets of support wheels, the machine slides on the guide rail 500 during tensioning, facilitating operation.

[0049] A tensioning mechanism 300 is mounted on the fixed section 100 and the movable section 200 for tensioning the tail wheel. In one embodiment, the tensioning mechanism includes a first mounting base 310, a second mounting base 320, and a tensioning assembly 330.

[0050] The first mounting base 310 is mounted on the fixed section 100. A first tension hole is machined on the first mounting base 310. The second mounting base 320 is mounted on the movable section 200. A second tension hole is machined on the first mounting base 320.

[0051] Tensioning assembly 330 is mounted on the first mounting base 310 and the second mounting base 320. In one embodiment, the tensioning assembly 330 includes a tensioning screw 331 and a tensioning nut 332. The tensioning screw 331 passes sequentially through a first mounting hole in the first mounting base and a second tensioning hole in the second mounting base. The tensioning screws 331 on both sides of the first tensioning hole are locked with tensioning nuts 332. The tensioning screws 331 on both sides of the second tensioning hole are also locked with tensioning nuts 332.

[0052] In one implementation, limiting components 340 are respectively provided at both ends of the tensioning assembly 330 to prevent the tensioning assembly from falling off the first mounting base and the second mounting base. Specifically, the tensioning assembly 340 includes a limiting plate 341 and a limiting pin 342. The limiting plate 341 is sleeved on the corresponding end of the tensioning screw 331. Limiting holes 343 are machined at both ends of the tensioning screw 331, and the limiting holes 343 are radially arranged. The limiting pin 342 is installed in the limiting hole 343, and the limiting pin 342 is located outside the limiting plate 341. A limiting baffle is provided at the end of each tensioning screw to prevent the tensioning screw from disengaging due to misoperation, which would be extremely difficult to reset. This can effectively reduce the number of limit sensors and lower equipment costs.

[0053] In one implementation, the tensioning mechanism 330 is installed on both sides of the fixed section 100 and the movable section 200, with two tensioning mechanisms arranged vertically on each side. A total of four sets of tensioning mechanisms are designed on both sides of the fixed and movable sections, which can effectively ensure the stability of the belt tension.

[0054] In one implementation, a limiting member 106 is provided on the fixed section 100 to limit the maximum distance between the movable section and the fixed section. The limiting member 106 can be provided independently or can utilize the connecting member 106 of the access door 105 as a limiting member. Specifically, the access doors on both sides of the fixed section housing and the connecting bolts on both sides of the access doors can limit the minimum distance between the movable section and the fixed section.
