Technical Field
[0001] The utility model relates to the technical field of solid material conveying, in particular to a novel transmission mechanism of a pipe chain conveyor. Background Art
[0002] At present, in a general chemical raw material conveying system, the sprocket box of a pipe chain conveyor requires a driving device, and the driving device usually uses a speed reducer and a motor; the speed reducer usually adopts the form of a parallel shaft speed reducer or an inclined bevel gear speed reducer, and the output shaft is in the form of a hollow shaft; the main shaft of the sprocket box is a protruding shaft and is inserted into the hollow shaft of the speed reducer. The sprocket box and the bottom of the speed reducer are supported by brackets on the ground. When the foundation of the bracket sinks or there are deviations in the manufacture of the bracket, the main shaft will receive a large axial force, and thus the shaft may break after being used for a period of time. Therefore, it is of great significance to provide a novel transmission type of a pipe chain conveyor that can solve the above problems. Content of the Utility Model
[0003] The purpose of the utility model is to solve the above deficiencies and provide a novel transmission mechanism of a pipe chain conveyor. By disconnecting the speed reducer from the main shaft of the sprocket box, adopting a sprocket and chain transmission method, and separately supporting the sprocket box and the speed reducer, when the bracket of the speed reducer sinks or there are deviations in the manufacture of the bracket, only the chain tension needs to be adjusted to avoid a large axial force on the main shaft of the sprocket box.
[0004] To achieve the above purpose, a novel transmission mechanism of a pipe chain conveyor is designed, which includes a bracket 2, a sprocket box 3, a motor 4, a speed reducer 5, an adjusting block 6, a first sprocket group 7a, a second sprocket group 7b, a chain 8 and a protective cover 9. The motor 4 is connected to the speed reducer 5, and the motor 4 and the speed reducer 5 are placed on the bracket 2. A first sprocket group 7a is installed at the output end of the speed reducer 5. The first sprocket group 7a is connected to the second sprocket group 7b through the chain 8. The second sprocket group 7b is installed on the main shaft of the sprocket box 3. The first sprocket group 7a, the second sprocket group 7b and the chain 8 are surrounded by the protective cover 9. Adjusting blocks 6 are arranged on both the left and right sides of the speed reducer 5, and the adjusting blocks 6 are welded to the bracket 2. The chain 8 is tensioned through the adjusting blocks 6.
[0005] Furthermore, fasteners 1 are installed on the top surface of the bracket 2. The fasteners 1 are distributed in a rectangular shape. The speed reducer 5 is locked to the bracket 2 through the fasteners 1, thus ensuring the installation stability between the speed reducer 5 and the bracket 2.
[0006] Furthermore, the speed reducer 5 is an inclined gear speed reducer. An output shaft extends outwards from the output end of the inclined gear speed reducer. The output shaft is connected to the first sprocket group 7a, so that the impact and vibration during the transmission process are small, and the transmission is more stable.
[0007] Further, the two sprockets of the first sprocket group 7a and the second sprocket group 7b in the protective cover 9 are horizontally placed, and the protective cover 9 is respectively connected to the speed reducer 5 and the sprocket box 3, further ensuring the overall structural stability of the first sprocket group 7a, the second sprocket group 7b and the chain 8.
[0008] Further, the sprocket box 3 is arranged on one side of the bracket 2. The sprocket box 3 and the bracket 2 are both placed on the ground, and the speed reducer 5 on the sprocket box 3 and the bracket 2 is separately supported, so that further adjustment of the chain tension can avoid large axial force on the main shaft of the sprocket box.
[0009] Further, the main shaft of the sprocket box 3 passes through the sprocket box 3, and a backstop is installed at the other end of the main shaft. The backstop is fixed to the box body of the sprocket box 3 through a torsion arm, so as to prevent the sprocket in the sprocket box 3 from rotating reversely.
[0010] Further, evenly distributed discs 10 are sleeved on the chain 8. Rollers 11 are respectively connected to the peripheries of the discs 10. A reinforcing rib 12 is sleeved on the chain 8. The reinforcing rib 12 is located on both sides of the disc 10 and is connected to the disc 10. Thus, during the process of conveying materials, the disc can be evenly stressed and avoid deviation.
[0011] Compared with the prior art, the utility model has a novel and simple structure and reasonable design. By disconnecting the speed reducer from the main shaft of the sprocket box and adopting a sprocket-chain transmission mode, and the sprocket box and the speed reducer are separately supported, when the support of the speed reducer settles or there is a deviation in the production of the support, only the chain tension needs to be adjusted to avoid large axial force on the main shaft of the sprocket box; moreover, the utility model can make the installation of the speed reducer and the sprocket box easier, the production of the speed reducer support simpler, and the placement position of the speed reducer more flexible; at the same time, the utility model can eliminate large axial force on the main shaft of the sprocket, avoid the main shaft of the sprocket box from breaking the shaft, and is worthy of popularization and application.

[0019] The main shaft of the sprocket box 3 passes through the sprocket box 3. A reverse stopper is installed at the other end of the main shaft. The reverse stopper is fixed to the box body of the sprocket box 3 through a torsion arm. This reverse stopper can prevent the sprocket in the sprocket box from rotating reversely. The inner hole of the reverse stopper can be connected to the main shaft of the sprocket box 3 through a key.
