Description

Technical Field

[0001] The utility model relates to a double rocker arm driven feeding device, belonging to the technical field of feeders. Background Art

[0002] A rocker arm feeder is a device for supplying bulk materials, which can supply materials such as coal blocks to other devices. It is an important conveying device for stamp charging coke making, and is used to feed the coal prepared in the coal tower into the coal box of the coal charging car.

[0003] At present, the existing rocker arm feeder realizes feeding by a single eccentric crank driving a bucket-shaped feeder to reciprocate. It adopts single-arm drive, and the eccentric disk connected to the reducer is subject to large lateral force, the output shaft of the eccentric disk has a low service life and breaks frequently. Also, because the existing rocker arm is an integral structure, when installing after breakage, the positions of the reducer and the feeding trough need to be adjusted before installation, which is very inconvenient for installation. Summary of the Utility Model

The reducer is a double-output shaft reducer, and drive disks are respectively installed on the two output shafts on both sides of the reducer. An eccentric rod is installed on each drive disk, and each eccentric rod is respectively connected to the sliding feeding trough through a rocker arm assembly. The rocker arm assembly includes an adjusting rod, a bushing installed at one end of the adjusting rod, and a bearing assembly installed at the other end of the adjusting rod. The bushing is installed on the control rod of the sliding feeding trough, and the bearing assembly is installed on the eccentric rod.

[0006] Preferably, the bearing assembly includes a bearing box, a bearing installed in the bearing box, and an end plate installed on the bearing box. The inner ring of the bearing and the end plate are installed on the eccentric rod, the outer ring of the bearing is installed in the bearing box, and the bearing box and the end plate are connected by multiple bolts. A gasket is also arranged between the bearing box and the end plate.

[0007] Preferably, the adjusting rod includes an adjusting tube and a movable screw rod. One end of the adjusting tube is installed with a bushing and internally provided with threads. The movable screw rod is installed in the adjusting tube. The other end of the adjusting tube is integrally provided with a positioning square tube. The end of the movable screw rod is provided with a square rod, and a control sleeve is installed on the square rod. One end of the control sleeve is a square hole and is sleeved on the square rod, and the outer wall of the other end is square and is used for inserting into the positioning square tube. The positioning square tube and the control sleeve are connected and fixed by a positioning bolt.

[0008] Compared with the prior art, the utility model has the following technical effects: The utility model has a simple structure and is convenient to use. It adopts double-arm drive, and drive disks are connected to the output shafts on both sides of the reducer. The drive disks evenly distribute the load, with uniform stress, which improves the service life of the rocker arm. At the same time, the rocker arm adopts a combined structure and can freely adjust its length, facilitating on-site installation and debugging. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the following further details the utility model with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0013] As Figures 1 to 3 shown, a double-rocker-arm drive feeding device includes a sliding feeding trough 1 and a reducer 2 installed on a frame. The reducer 2 is a double-output-shaft reducer, and drive disks 3 are respectively installed on the output shafts on both sides of the reducer 2. An eccentric rod is installed on each drive disk 3, and each eccentric rod is respectively connected to the sliding feeding trough 1 through a rocker-arm assembly 4. The rocker-arm assembly 4 includes an adjusting rod 5, a bushing 6 installed at one end of the adjusting rod, and a bearing assembly 7 installed at the other end of the adjusting rod. The bushing 6 is installed on the control rod of the sliding feeding trough 1, and the bearing assembly 7 is installed on the eccentric rod.

[0014] The utility model adopts a double-output-shaft reducer. By installing two rocker-arm assemblies 4 on the output shafts of the double-output-shaft reducer and using the two rocker-arm assemblies 4 to drive the sliding feeding trough 1 for feeding, compared with the single-arm structure, the stress is uniform, and the service life of the rocker arm is improved. At the same time, the rocker arm adopts a telescopic structure, and the length adjustment is realized by using the adjusting rod 5, which facilitates the installation of the rocker arm when the rocker arm breaks. One end of the adjusting rod 5 is installed on the eccentric rod of the drive disk 3 through the bearing assembly 7, and the other end is installed on the control rod of the sliding feeding trough 1 through a bushing, which is convenient for installation and maintenance.

[0015] Among them, the bearing assembly 7 includes a bearing box 8, a bearing 9 installed inside the bearing box, and an end plate 10 installed on the bearing box. The inner ring of the bearing 9 and the end plate 10 are installed on the eccentric rod. The outer ring of the bearing 9 is installed inside the bearing box 8. The bearing box 8 and the end plate 9 are connected by a plurality of bolts, and a gasket is also provided between the bearing box 8 and the end plate 9. The bearing assembly 7 adopts a closed structure, which can play a role in dust prevention and extend the service life of the bearing.

[0016] As Figure 3 shown, the adjusting rod 5 includes an adjusting tube 11 and a movable screw rod 12. A bushing 6 is installed at one end of the adjusting tube 11, and the inside is provided with threads. The movable screw rod 12 is installed inside the adjusting tube 11. A positioning square tube 13 is integrally provided at the other end of the adjusting tube 11. A square rod 14 is provided at the end of the movable screw rod 12. A control sleeve 15 is installed on the square rod 14. One end of the control sleeve 15 is a square hole and is sleeved on the square rod 14. The outer wall of the other end is square and is used for insertion into the positioning square tube 13. The positioning square tube 13 and the control sleeve 15 are connected and fixed by a positioning bolt 16. The adjusting rod 5 adopts a structure in which the movable screw rod 12 and the adjusting tube 11 are threadedly connected. At the same time, the movable screw rod 12 installs the control sleeve 15. The control sleeve 15 mainly plays a locking role. When the control sleeve 15 is separated from the positioning square tube 13, the movable screw rod 12 and the adjusting tube 11 can rotate relative to each other to achieve adjustment. When the control sleeve 15 is inserted into the positioning square tube 13 and locked by the positioning bolt 16, since the movable screw rod 12 cannot rotate, the length cannot be adjusted either. During installation, first adjust the length of the adjusting rod 5, and then install the bushing 6.

[0017] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the scope of the present invention.
