Abstract
The invention provides a vertical belt middle sampling head, which comprises a frame structure, a sampling bucket structure and a multiple supporting rollers supporting construction; the sampling head frame is formed into door frame type structure; the sampling bucket is connected to the connection plate on the transmission shaft by a bolt; the transmission shaft is suspended in the middle position on the inner side of the frame by an integrated vertical bearing seat; multiple supporting rollers support is adopted on both sides of the sampling bucket; the belt on the sampling position is shaped more approaching to arc; a discharging opening is disposed on outer side of the supporting rollers. The sampling buckets rotates around the shaft to obtain the materials from the whole section, and dumps to the discharging opening; and completes one sampling period once rotating one cycle. The invention adopts vertical door frame structure, has a flexible mounting position, can be mounted in the whole working intermediate section of the belt conveyor, is not influenced by the central rack of the belt support, is suitable for large-width belt; and the belt is shaped more approaching to arc accordance with the sampling bucket movement track, thus the sampling bucket sampling section is more perfect to has no surplus material.
Description
Technical field
The present invention relates to a kind of sample devices, specifically refer to a kind of belt middle part is used for gathering sample of material on the operation belt equipment that is installed on.
Background technology
The belt middle sampling head is to be installed on the band conveyor middle part, is used to gather the material on the operation conveying belt.Scrape the bucket type sampling head and be installed in band conveyor middle part, rotate a circle according to the time cycle of setting, obtain the material sample of a complete cross-section, be used for the quality of pick test material from the band conveyor of operation.
The existing bucket type sampling head of scraping is the rack horizontal type structure, is installed on the middle frame at belt middle part, and work space is little, mainly is used in belt width＜1400mm, under the condition of operational throughput＜1500t/h.Along with the increase of operational throughput, to carry bigger raw meal particle size simultaneously, the width of band conveyor also increases thereupon, and the belt feeder of belt width 〉=1400mm is more and more general.Generating set capacity such as power plant increases, the single-machine capacity of present domestic thermal power plant reaches 1000MW, belt feeder coal-feeding quantity hourly reaches more than the 3500t, the belt width of belt feeder reaches more than the 1600mm, the coal conveyer belt width that the 1000MW genset is used then reaches 1800mm, and the belt width of the coal conveyer belts that the colliery is used more reaches 2200mm.The sampling quantity workload increases, and the A/F of sampling bucket increases with the increase of sampling granularity, and transmission power increases, and the gear train volume is big, and the installing space of the direct-connected transmission of horizontal type structure is restricted, and can not satisfy the requirement of relatively large belt conveyor sampling.The support carrying roller of general belt feeder is 35 ° of flute profile carrying rollers, be 3 carrying roller supporting forms, vertical with belt direction of travel or have a certain degree because of the sense of rotation of sampling bucket, belt is shaped variant with the movement locus of sampling bucket, cause sampling process to have clout, can not obtain complete material sample, cause representative deviation.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of and be fit to relatively large band conveyor and adapt to the big vertical belt middle sampling head of raw meal particle size scope.
The present invention is achieved by the following scheme:
A kind of vertical belt middle sampling head comprises rack construction, sampling bucket structure, many carrying rollers supporting construction.
The sampling head frame adopts portal framed structure, frame to be installed in independently on the floor stand, is not subjected to the influence of belt feeder support and middle frame; The installation site is flexible, all can install in band conveyor work stage casing.
The sampling bucket links by the web joint on bolt and the transmission shaft, adopts the integral vertical type bearing seat that transmission shaft is suspended on frame middle inside position.Adopt many carrying rollers to support in sampling bucket belt conveyor bottom, both sides, the global sections of whole group carrying roller is shaped more near circular arc the belt at sampling position near circular arc.The quantity of single group carrying roller determines that according to belt width 5 carrying rollers, 7 carrying rollers, 9 carrying rollers are arranged, and is not limited thereto.There is discharging opening in the carrying roller outside.The sampling bucket pivots, and obtains the material of a complete cross-section, pours discharging opening into.Rotate a circle, finish primary sample.
The invention has the beneficial effects as follows: adopt vertical portal framed structure, the installation site is flexible, all can install in band conveyor work stage casing, is not subjected to the influence of belt support and centre frame, is applicable to big width belt; Belt is shaped and more meets the movement locus of sampling bucket near circular arc, and sampling bucket sampling cross section is more complete, does not stay clout.
