Abstract
The utility model provides an individual scrapping knife device for a belt conveyor. One end of a support arm of a scrapping knife frame is hinged with a truss, and while the other end of the support arm is connected with an adjusting handle, wherein a scrapping knife in contact with a belt is arranged on the support arm of the scrapping knife through the scrapping knife frame. According to the individual scrapping knife device for the belt conveyor, the individual scrapping knife frame and the scrapping knife are arranged, thus, the cement mortar on the belt can be conveniently and timely removed, and the aggregates can be prevented from being separated due to the loss of the mortar during conveying the concrete; and the concrete pouring quality is ensured, and at the same time a tape conveying face is kept cleaning; and the individual scrapping knife device not only has benefit to the site safe and civilized construction, but also has the benefit to prolong the service life of the belt.
Description
Technical field
The utility model relates to the transmission and concrete transmission field, the split type doctor blade device of particularly a kind of band conveyor.
Background technology
In the concrete pouring construction of power station, cement concrete is transported to lift surface from the system of mixing and stirring and generally adopts band conveyor, and band conveyor is in operational process; Cement mortar very easily is bonded on the belt, if untimely removing not only influences on-the-spot civilized construction; Cement mortar is to the wearing and tearing of belt, and with the service life that shortens belt, belt ruptures when serious; Cause stopping production, not only influence concrete pouring quality, even safety misadventure occurs.
Summary of the invention
The utility model technical matters to be solved provides the split type doctor blade device of a kind of band conveyor; Can the cement mortar that be bonded on the band conveyor belt in time be removed; Prevent that the mortar loss causes aggregate separated in the transmission and concrete transmission, when guaranteeing concrete pouring quality, also keep the clean of adhesive tape conveyor surface; Both help the site safety civilized construction, also helped prolonging the service life of belt.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: the split type doctor blade device of a kind of band conveyor; Two doctor blade holder support arm one ends are hinged with truss respectively; The other end is connected with regulating handle through peg, through doctor blade holder the scraper that contacts with belt is installed between two doctor blade holder support arms.
In the described doctor blade holder, support body or scraper pressing plate are provided with the stage that is used to hold scraper, and the scraper pressing plate is connected with support body through push bolt.
Described doctor blade holder is positioned at the end positions of scraper.
The rear side of described doctor blade holder also is provided with check apron.
Described scraper is positioned at the position of head roll below.
Described scraper is positioned at the head roll below, near the position of belt and head roll contact wire.
The split type doctor blade device of a kind of band conveyor that the utility model provides; The split type doctor blade holder and the scraper that are provided with can in time be removed the cement mortar that is bonded on the belt easily, prevent that the mortar loss causes aggregate separated in the transmission and concrete transmission; When guaranteeing concrete pouring quality; Also keep the clean of adhesive tape conveyor surface, both helped the site safety civilized construction, also help prolonging the service life of belt.The split-type structural that adopts has alleviated the weight at scraper position, is more prone to change scraper or doctor blade holder, reduces belt feeder operations staff's labour intensity.Further, the check apron of setting can be avoided waste or the pollution that splashing of cement mortar caused.Scraper is positioned near belt and head roll contact wire position, and the belt distortion allowance here is less, has guaranteed the clear quality of scraper, also can not form rigid contact simultaneously, has lowered the wearing and tearing to belt.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the cutaway view of the A-A of Fig. 1.
Fig. 4 is the partial enlarged drawing at C place among Fig. 1.
Fig. 5 is the cutaway view of the B-B of Fig. 4.
Among the figure: scraper 1, doctor blade holder 2, doctor blade holder support arm 3, regulating handle 4, check apron 5, scraper pressing plate 6, truss 7, peg 8, head roll 9, belt 10, stop cylinder 11, push bolt 12, support body 13.
The specific embodiment
In Fig. 1-5, two doctor blade holder support arm 3 one ends are hinged with truss 7 respectively, and the other end is connected with regulating handle 4 through peg 8, through doctor blade holder 2 scraper 1 that contacts with belt 10 is installed between two doctor blade holder support arms 3.
In Fig. 4,5, in the described doctor blade holder 2, support body 13 or scraper pressing plate 6 are provided with the stage that is used to hold scraper 1, and scraper pressing plate 6 is connected with support body 13 through push bolt 12, and scraper 1 is clamped between scraper pressing plate 6 and the support body 13.
In Fig. 1-3, described doctor blade holder 2 is positioned at the end positions of scraper 1.
In Fig. 1, the rear side of described doctor blade holder 2 also is provided with check apron 5.Check apron 5 in this example adopts iron wire that old adhesive tape is fixed on the supporting steel pipe, is weldingly fixed on then on the truss 7 of band conveyor.Be rear side with the left side among Fig. 1 in this example.
In Fig. 1, in the scheme of optimization, described scraper 1 is positioned at the position of head roll 9 belows.
In Fig. 1, in the scheme of further optimizing, described scraper 1 is positioned at head roll 9 belows, near the position of belt 10 with head roll 9 contact wires.
Doctor blade device in this example is split as the two large divisions, and a part is a scraper, and it mainly act as the mortar of removing belt 10 surfaces, prevents that the mortar loss causes aggregate separated in the transmission and concrete transmission, keeps the clean of belt 10 conveyor surfaces simultaneously; Another part is check apron 5 and fixed support, and main effect is the mortar that blocks the scraper cleaning, makes mortar can flow into down the bar belt conveyor again.
1. the utility model is designed to split formula structure, has also alleviated the weight at scraper position, is more prone to change scraper or doctor blade holder, reduces belt feeder operations staff's labour intensity, is a kind of simple effective, economic convenient and failure-free doctor blade device.
2. doctor blade holder support arm 3 one end hinged securement are on conveyor head section truss 7; The other end is connected on the truss of belt top through the regulating handle 4 of adjustable length; Adopt the spring tension on the regulating handle 4 to make doctor blade holder 2 assemblies be close to belt 10; The flexible characteristic of spring can play certain compensating action to the springing in belt 10 operational processs, effectively prevents the generation of spillage phenomenon.And doctor blade holder 2 assemblies are positioned near the position of belt 10 with head roll 9 contact wires, and the belt elastic deformation leeway here is less, has guaranteed the clear quality of scraper, also can not form rigid contact simultaneously, have lowered the wearing and tearing to belt.
3. check apron 5 usefulness iron wires are hung colligation on supporting steel pipe, then supporting steel pipe is welded on the belt feeder truss 7.Check apron 5 is controlled at about 200mm with scraper 1 distance.
4. when using: head roll 9 clockwise rotates; Drive the motion of belt 10 cws; Belt 10 upper surface convey materials are for example: cement concrete, after convey materials was walked out belt 10 above the head roll, belt 10 encased head roll 9 walkings successively through scraper 1, check apron 5.Through scraper 1 time, material residual on the belt 10 is by under scraper 1 retaining.Because belt 10 running velocitys are higher, the partial material that under effect of inertia, has broken away from belt 10 surfaces can fly out along belt direction of travel, and this part material will be kept off down by check apron 5, thereby guarantees that material all is transported to assigned address.
