Description
Technical Field
The invention relates to the technical field of belt cleaners, in particular to a bidirectional self-adjusting first belt cleaner.
Background
When the belt conveyor carries out belt material operation, due to inertia and adhesive force, some fine powder particles do not fall into the nose hopper from the nose roller completely, but are gradually scattered on the ground behind the surface-increasing roller and the bottom parallel carrier roller along with the belt return path, so that the materials are accumulated, as shown in fig. 1.
In order to solve the problem of belt material of the return belt, a plurality of types of belt cleaners need to be installed on the head of the belt conveyor, wherein the conventional first belt cleaner is a device capable of effectively removing the adhered particles on the surface of the return belt, and the cleaning principle is shown in fig. 2.
In the traditional first belt cleaner, a high-molecular polyurethane scraper (also called a blade) is arranged on a main frame, the axis of the main frame is fixed, the positions of the scraper and a belt are adjusted, and the cleaner is firmly arranged after being fixed. And screwing the large nut to tightly press the spring sleeved on the screw rod, wherein the elastic force of the spring acts on the tension arm, so that the torque is applied to the main frame, and the scraper edge is tightly pressed on the belt. The belt head wheel rotates to drive the belt to move, the static scraper blade rubs with the surface of the moving belt, and particles adhered to the surface of the belt are scraped off, so that the purpose of cleaning the surface of the belt is achieved. When the scraper edge is worn, the front end of the scraper always presses the surface of the belt under the action of torque.
This device has the following disadvantages:
1) after the scraper edge is abraded, the cleaning effect on the belt is weakened
Along with the abrasion of the scraper edge, the abraded scraper rotates anticlockwise around the fixed axis of the main frame, so that the contact surface of the scraper and the belt moves downwards, and when the contact surface moves to a position 5 cm below the horizontal line of the head pulley downwards, the cleaning effect is greatly reduced gradually until the contact surface fails.
2) The scraper blade is ground flat to increase the running resistance of the belt conveyor
Along with the continuous wearing and tearing of scraper sword, the scraper is rotatory around main frame fixed axis anticlockwise, and the scraper wearing surface is wider and wider, and with belt area of contact constantly enlarge, frictional resistance increases along with it by a wide margin, leads to the belt feeder load increase, directly influences the normal steady operation of belt feeder equipment.
3) The scraper is seriously worn and has the hidden trouble of turning over the scraper
Along with the continuous wearing and tearing of scraper, the scraper is bigger and bigger around the anticlockwise rotatory angle of main frame fixed axis, and when the scraper was close perpendicular with the belt surface, scraper and main frame were turned over by the belt very easily this moment, in case the upset, whole platform sweeper can seriously warp, and the sweeper that warp even can rip the belt, causes serious equipment accident and economic loss.
4) The scraper of the sweeper has quick failure and high running cost
For avoiding because scraper wearing and tearing, cause to clean the effect and weaken, with the increase of belt frictional resistance, the scraper probably upset etc. influence the emergence of the normal steady operation condition of sweeper and belt feeder equipment, after scraper sword wearing and tearing, just need in time to change the scraper, traditional first belt sweeper scraper change frequency is very fast, has increased the sweeper operation maintenance cost.
Therefore, it is an urgent technical problem to be solved by those skilled in the art to provide a belt sweeper with simple structure, convenient maintenance, safety and reliability.
