Abstract
The utility model relates to a three-chain type scraping plate device for a development machine. A scraping plate is connected with three circular chains with equal distance, both ends of the scraping plate are provided with peach-shaped rings connected with the chains, and both sides of the middle part of the scraping plate are provided with half connecting rings connected with the chains. The utility model with simple structure and reasonable design increases the entire tensile strength of the conveyer scraping plate device and solves the problem of easy bending or breaking of the scraping plate after being pressed so as to make the conveyer work more reliably.
Description
Technical field
The utility model relates to a kind of development machine shipment portion screeding device.
Background technology
At present, the scraper component of development machine has two kinds: a kind of is bilateral chain form, and a kind of is the double center chain form.Bilateral chain form round-link chain is fixed on the two ends of scraper plate, and in the process of haul, when overload took place transporter, scraper plate bent or fractures because of stressed conference excessively.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, the more reliable development machine three chain scraper devices of transporter work.
In order to achieve the above object, the technical solution adopted in the utility model is: the circular chain of scraper plate and three equidistant arrangements joins, and the scraper plate two-end part is equipped with peach shape ring and joins with chain, and half connecting ring is housed both sides, scraper plate middle part and chain joins.
The utility model has the advantages that:
Whole tensile strength simple in structure, reasonable in design, as to have improved the conveyer scraper device has solved the problem that bends easily or fracture after scraper plate is stressed, makes transporter work more reliable.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is that the circular chain 1,2,3 of scraper plate 5 and three equidistant arrangements joins, and scraper plate 5 two-end parts are equipped with peach shape ring 6 and join with chain 1,3, and both sides, scraper plate 5 middle part are equipped with half connecting ring 4 and are joined with chain 2.
Screeding device is the critical piece of development machine first transporter part, it mainly by, parts such as round-link chain, connecting ring and scraper plate are formed, and according to the position difference of round-link chain, can be divided into two kinds of forms of bilateral chain and double center chain again.Bilateral chain structure be round-link chain at two ends, scraper plate is in the centre, the two is connected by connecting ring, round-link chain drives scraper plate motion under the traction of sprocket wheel, transport material backward.Round-link chain is installed in the centre of scraper plate in the double center chain structure, drives scraper plate by sprocket wheel traction round-link chain and transports material.Three chain scraper devices are different from top two kinds of form of structure, and it has improved bilateral chain structure, outside two round-link chains at two ends, increase a round-link chain in the middle of scraper plate, are connected with scraper plate by the two halves connecting ring.Sprocket wheel moves together with advancing three chains of traction, scraper plate two ends and middle simultaneously stressed, not flexible.When transported material, three chain scraper device scraper plates are stressed evenly, reduced the generation of the scraper plate bending and the phenomenon that fractures, and improve the application life and the conevying efficiency of screeding device.
