Background technology
In the pelletizing production technique of drying grate and rotary kiln, shovel flitch be mounted on chain grate head, play by pelletizing with Drying grate detaches, and shovel flitch is the important equipment for guiding pelletizing to enter rotary kiln.When drying grate is run, grate runs line along grate Rotation.Grate upper surface is covered with pellet, and shovel flitch needs to keep suitable distance between grate, ensures that pellet is de- when grate rotation From grate, while also needing to ensure that shovel flitch cannot be scraped with grate.Shovel flitch can rotate around the axis, shovel flitch and grate gap It is adjusted by plate thickness.When drying grate is run, inevitably has pelletizing or other sundries enter between shovel flitch and grate Gap, will result in shovel flitch tilting in this way, material leakage amount surges.Because shovel flitch is operated in 1200 DEG C or so of high temperature ring Border, shaft operating is not bery flexible, and the counterweighted take-up of former shovel flitch is through cannot often reset after shovel flitch tilting, and need to stop production place Reason, causes very big loss.
Consult disclosed patent document, open (bulletin) number:102050328B discloses spading plate in grate-kiln and jacks up machine The counterweight that structure includes the pull rod hinged with shovel flitch and is connect with this pull rod, pull rod lower part are connected with a link mechanism, this The oscillating rod that link mechanism is hinged by upper bracket, middle part with this upper bracket, the connecting rod being hinged with the left end of this oscillating rod, The operating lever being hinged with the lower end of this connecting rod, the undersetting being hinged with this operating lever are located on this undersetting Caging bolt is formed, and the right end of oscillating rod is fixedly connected with pull rod lower part, and upper bracket and undersetting are solid successively from top to bottom It is scheduled in the rack of drying grate, the lower end of caging bolt is mutually abutted against with the upper surface of operating lever.
Open (bulletin) number:100418865, disclose a kind of adjustable feeding plate of grate, material-shovelling board face and in Between plate be in spoon shape, the protection bed of material can be accumulated;It is hammered into shape by lift heavy under branch shovel flitch on sunpender with special adjustment block, it can be outside machine The gap of random adjustment shovel flitch and grate face, adjusts sideshake with side shovel head, shovel flitch is controlled to greatest extent to facilitate Material leakage disadvantage improves shovel flitch stress, heated working condition.These inventions are by weight and manually shovel flitch to be made to reset, no It is capable of the position of real-time control shovel flitch.
Invention content
The purpose of this utility model is to provide a kind of elastic stretching device of spading plate in grate-kiln, this tensioning apparatus can be controlled The gap size of shovel flitch and grate processed prevents shovel flitch from scratching grate, reduces material leakage amount.
A kind of elastic stretching device of spading plate in grate-kiln provided by the utility model, including be arranged in hopper and shovel flitch Between link assembly and the elastic parts being connect with link assembly in hopper outer wall is set,
The link assembly is made of axis pin, upper hanger, universal joint and lower sunpender, in the upper end of the upper hanger It is provided with upper shaft hole, the upper shaft hole of upper hanger is rotatablely connected by axis pin and shovel flitch, and the lower end of upper hanger is by universal joint under The upper end of sunpender connects, and screw thread is additionally provided in the lower end of lower sunpender;
The elastic parts by spring base, be successively set on the spring of spring base lower part and the baffle institute group with through-hole At;
The spring base is L-shaped spring base, is arranged the outside in hopper lower part, two upper ends of L-shaped spring base with Hopper wall outer surface contacts, L-shaped spring base be in horizontality on one side equipped with through-hole, the lower end of the lower sunpender is worn Hopper side wall, the through-hole on spring base and spring is crossed to fasten by adjusting nut and baffle;
The elastic stretching device of the spading plate in grate-kiln, it is characterised in that the spring is compression spring.
The utility model significantly has the beneficial effect that compared with the elastic stretching device of existing similar shovel flitch:
(1)Using this elastic stretching device, so that sunpender is ensured that shovel flitch is in always by the pulling force that spring generates and compress State, when drying grate is run, in the presence of a tensile force, shovel flitch jacks up height and becomes larger, and prevents shovel flitch from being scraped with grate;
(2)Spring can control the gap size of shovel flitch and grate in tensioning apparatus, when shovel flitch jack up it is too high, be tensioned Under spring effect in device, shovel flitch can be pulled down.It has prevented pelletizing or other sundries from entering between shovel flitch and grate, has caused Material leakage amount surges;
(3)The utility model is simple in structure, easy to use, using this shovel flitch elastic stretching device when, can control The gap size of shovel flitch and grate prevents shovel flitch from scratching grate;Reduce material leakage amount, prevents from often stopping production, improve production Efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, there is shown, the elastic stretching device of a kind of spading plate in grate-kiln of the utility model, including be arranged in hopper Interior link assembly between shovel flitch and the elastic parts being connect with link assembly in hopper outer wall is set,
The link assembly is made of axis pin 1, upper hanger 2, universal joint 3 and lower sunpender 4, in the upper hanger 2 Upper end be provided with upper shaft hole, the upper shaft hole of upper hanger 2 is rotatablely connected by axis pin 1 and shovel flitch 10, and the lower end of upper hanger 2 passes through Universal joint 3 is connect with the upper end of lower sunpender 4, and screw thread is additionally provided in the lower end of lower sunpender 4;
The elastic parts by spring base 5, be successively set on the spring 6 of 5 lower part of spring base and the baffle 7 with through-hole It is formed, the spring 6 is compression spring.
