Abstract

The invention discloses a cleaning device for a belt conveyor. The cleaning device comprises two oscillating bars, a fixed shaft, a fixed bearing, a steel pipe, a cleaning plate and a scraping plate, wherein the fixed shaft is fixed on a shell of the belt conveyor through a bearing; the steel pipe is sleeved on the fixed shaft; one end of the cleaning plate is fixedly connected with the steel pipe; an abrasion-proof material is adhered to edges of the other end of the cleaning plate to form the scraping plate; each oscillating bar consists of a main bar, a fixed ring, a positioning bar, a limit pipe and a spring; the oscillating bars and the cleaning plate are fixedly connected with the fixed shaft; when resistance of a material is applied to the cleaning plate, the oscillating bars block the fixed shaft from rotating under the action of the tensioning force of the spring, so that the cleaning plate receives the tensioning force which is opposite to resistance force of the material and is always pressed against a conveyor belt, and the cleaning device can steadily and efficiently scrape off the material left on the conveyor belt.

Description

The clearing apparatus that is used for belt conveyer

Technical field

The present invention relates to a kind of clearing apparatus for belt conveyer head.

Background technology

The material that belt conveyer is carried is bulk cargo, and discharging opening is arranged on head, when the head discharging, has certain bulk cargo and remains on the load-transfer device, must when load-transfer device leaves discharging opening, the material that sticks on the load-transfer device be scraped off.The setting of the swabbing pig of existing belt conveyer is generally scraper plate is set above load-transfer device, operation along with load-transfer device, scraper plate scrapes off material, but the continuous increase along with material, scraper plate strikes off the also constantly increase of resistance that material is subject to, might occur that scraper plate is stressed to be subjected to displacement, thereby make the gap of scraper plate and load-transfer device become large, cause material scraper to remove unclean.

Summary of the invention

The invention provides a kind of swabbing pig for belt conveyer, can actv. strike off in the belt conveyer operational process material residual on the load-transfer device.

The structure of the swabbing pig for belt conveyer of the present invention comprises two forks, anchor shaft, fixed type bearing, steel pipe, cleaning board and scraper plates;

Anchor shaft is fixed on through fixed type bearing on the housing of belt conveyer, steel pipe socket anchor shaft, and cleaning board one end captive joint steel pipe, an end margin adheres to high-abrasive material becomes scraper plate;

Fork is comprised of mobile jib, set collar, radius stay, position-limiting tube and spring; Set collar is arranged on an end of mobile jib, Fixing shrink ring is connected on fixedly the tip of the axis, the vertical captive joint radius stay of the other end of mobile jib and position-limiting tube, position-limiting tube inner sleeve radius stay, the other end captive joint of radius stay and the housing of belt conveyer, spring places between position-limiting tube and the radius stay.

Fork is all captiveed joint and anchor shaft with cleaning board, when cleaning board was subject to the resistance of material, fork was subject to the tensile force impact of spring, hinders the rotation of anchor shaft, thereby make cleaning board also be subject to the tensile force reverse with the resistance of material, make cleaning board be close to load-transfer device always.

Be provided with bearing (setting) plate, fixed type bearing is installed on housing by bearing (setting) plate.Bearing (setting) plate is so that captiveing joint of the housing of fixed type bearing and conveyer is more fastening.

Swabbing pig for belt conveyer of the present invention also is subject to the tensile force that spring applies when striking off material, thereby the scraper plate of swabbing pig can not be subjected to displacement because of the resistance of material, in material conveying process always stability and high efficiency strike off material.

Fig. 4 is the structural representation of the fork of the swabbing pig for belt conveyer of the present invention.

The housing of 1 belt conveyer among the upper figure, 2 forks, 3 anchor shafts, 4 steel pipes, 5 cleaning boards, 6 scraper plates, 7 mobile jibs, 8 great wheels, 9 position-limiting tubes, 10 radius stays, 11 springs, 12 set collars, 13 swabbing pigs, 14 fixed type bearings.

Specific embodiment

A kind of swabbing pig of belt conveyer is comprised of two forks 2, anchor shaft 3, fixed type bearing 14, steel pipe 4, cleaning board 5 and scraper plate 6;

Anchor shaft 3 is fixed on the housing 1 of belt conveyer through fixed type bearing 14 and bearing (setting) plate (not illustrating in the drawings), and steel pipe 4 is fixed by socket axle 3, and cleaning board 5 one end captive joint steel pipes 4, one end margins adhere to high-abrasive material becomes scraper plate 6;

Fork 2 is comprised of mobile jib 7, set collar 12, radius stay 10, position-limiting tube 9 and spring 11; One end of mobile jib 7 is set collar 12, set collar 12 is socketed in the end of anchor shaft 3, the vertical captive joint radius stay 10 of the other end of mobile jib 7 and position-limiting tube 9, position-limiting tube 9 inner sleeve radius stays 10, the other end captive joint of radius stay 10 and the housing 1 of belt conveyer, spring 11 places between position-limiting tube 9 and the radius stay 10.

Fork 2 is all captiveed joint and anchor shaft 3 with cleaning board 5, when cleaning board 5 is subject to the resistance of material, fork 2 is subject to the tensile force impact of spring 11, hinder turning of anchor shaft 39 moving, thereby make cleaning board 5 also be subject to the tensile force reverse with the resistance of material, make cleaning board 5 be close to load-transfer device (not illustrating in the drawings) always.

Claims

1. a swabbing pig that is used for belt conveyer is characterized in that comprising two forks, anchor shaft, fixed type bearing, steel pipe, cleaning board and scraper plates;

Described anchor shaft is fixed on through bearing on the housing of belt conveyer, steel pipe socket anchor shaft, and cleaning board one end captive joint steel pipe, an end margin adheres to high-abrasive material becomes scraper plate;
