Description

Technical Field

[0001] The utility model relates to the technical field of hopper anti-blocking, in particular to a hopper anti-blocking device at the head of a conveyor belt. Background Art

[0002] With the diversity of material transportation, when the moisture content of the material is high, the material will not flow smoothly and will easily adhere to the receiving hopper at the head of the belt conveyor, which can easily lead to coal accumulation in the hopper and poor material discharge, causing the hopper to be blocked. The wall blockage affects the fuel transportation efficiency, seriously affects the safe and stable operation of the unit, and increases the labor intensity of the workers. Utility Model Content

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a conveyor belt head hopper anti-blocking device which is easy to install, stable in operation and has a good anti-blocking effect.

[0004] The utility model is realized in this way, a conveyor belt head hopper anti-blocking device comprises a shell arranged on the hopper, the shell is provided with a middle hole matching the hopper discharge port, a toothed disc rotatably connected to the shell is provided inside the shell, a driving mechanism for driving the toothed disc to rotate is provided on the shell, and a blockage-clearing scraper is provided on the inner side of the toothed disc.

[0005] The shell includes an upper connecting cylinder, a middle rotating cylinder and a lower connecting cylinder.

[0006] The gear disc is rotatably connected to the housing via a slewing bearing.

[0007] The middle rotating cylinder is arranged on the gear disc, the slewing bearing is arranged on the middle rotating cylinder, and the middle rotating cylinder is provided with a blockage clearing scraper.

[0008] The driving mechanism adopts a driving motor.

[0009] The driving gear of the driving mechanism is meshed with the toothed disc.

[0010] When the device is in use, the driving mechanism can be started regularly to drive the toothed disc to rotate, and the toothed disc drives the blockage-clearing scraper to rotate, so as to break up and scrape off the materials stuck on the inner wall of the hopper. The driving mechanism can rotate forward and reverse to scrape off the materials that are agglomerated or stuck on the inner wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described below in conjunction with the accompanying drawings:

[0012] Figure 1 It is a cross-sectional structural schematic diagram of an embodiment of the utility model;

[0013] Figure 2 It is a main structural schematic diagram of the utility model;

[0015] Figure 4 It is a cross-sectional structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0016] Example 1: Figure 1 As shown, a conveyor belt head hopper anti-blocking device includes a shell 7 arranged on the hopper, the shell 7 is provided with a center hole 12 matching the hopper discharge port, the shell 7 is provided with a gear plate 8 rotatably connected thereto, the shell 7 is provided with a driving mechanism 5 for driving the gear plate 8 to rotate, and the inner side of the gear plate is provided with a clearing scraper 4.

[0017] A positioning cylinder 10 is provided under the toothed disc, and a positioning groove matching the positioning cylinder 10 is provided in the housing 7. The positioning cylinder plays a positioning role, and the toothed disc and the positioning cylinder are an integrated structure. The rotation of the toothed disc drives the clearing scraper to rotate, and the blockage in the feed hopper is cleared.

[0018] The pressure cover 11 on the housing plays the role of positioning the gear disc.

[0019] The structure of embodiment 1 is simple and the operation is stable.

[0020] Example 2: Figure 2-4 As shown, a conveyor belt head hopper anti-blocking device includes a shell 7 arranged on the hopper 7, the shell 7 is provided with a middle hole 12 matching the hopper discharge port, the shell 7 is provided with a gear plate 8 rotatably connected thereto, the shell 7 is provided with a driving mechanism 5 for driving the gear plate 8 to rotate, and the shell 7 includes an upper connecting cylinder 7, a middle rotating cylinder 2 and a lower connecting cylinder 6.

[0021] The toothed disc 8 is rotatably connected to the housing 7 via a slewing bearing 3 .

[0022] The middle rotating cylinder 2 is arranged on the gear disc 8 , the slewing bearing is arranged on the middle rotating cylinder 2 , and the middle rotating cylinder 2 is provided with a blockage clearing scraper 4 .

[0023] The driving mechanism 5 adopts a driving motor.

[0024] The driving gear 9 of the driving mechanism 5 is meshed with the gear wheel 8 .

[0025] The advantage of Example 2 over Example 1 is that bearings are used, resulting in low rotational friction.

[0026] When the device is in use, the driving mechanism can be started regularly to drive the toothed disc to rotate, and the toothed disc drives the blockage-clearing scraper to rotate, so as to break up and scrape off the materials stuck on the inner wall of the hopper. The driving mechanism can rotate forward and reverse to scrape off the materials that are agglomerated or stuck on the inner wall.
