Background
The tail guide chute of the sintering machine is positioned between the tail of the sintering machine and the single-roll crusher, is one of very important links on a sintering production line, and the reliability of the tail guide chute is very important for the stability of the whole sintering production. Usually, the relative height difference between the sintering machine table surface and the single-roller crushing machine table surface is more than four meters, when the sintering machine trolley discharges materials, the temperature of hot sintering ore is between 750 and 850 ℃, the weight of the sintering ore discharged by each trolley can reach seven tons, the fall reaches three meters, the impact force is quite large, and the discharge end of the sintering machine is seriously abraded due to the long-term washing of the high-temperature sintering ore. And the guide chute works continuously at high temperature for twenty-four hours, so that the abrasion of equipment is accelerated, and the service life of the guide chute is short. Particularly, the upper square steel and the lower square steel of the guide chute are easy to be directly impacted by hot sintering ores, the abrasion is the most serious, adjustment treatment needs to be carried out every three months, and replacement needs to be carried out every half year. The maintenance of each time is from shutdown, material cleaning, welding repair and replacement, which is time-consuming and labor-consuming and seriously affects the operation rate of the equipment. The equipment cost is also increased, so that a guide chute with prolonged service life is urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sintering machine tail baffle box can increase of service life, reduces and overhauls the number of times, improves sintering machine operation rate, practices thrift the cost, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
a guide chute at the tail of a sintering machine comprises a material groove and a base, wherein the material groove is fixed on the base; the material groove is formed by combining a back plate, two side plates and a bottom plate, a plurality of blanking pockets are sequentially arranged in the material groove from top to bottom, the plurality of blanking pockets form a multi-stage trapezoid, the back plate in the material groove is provided with a back plate buffering material pocket, and the side plates in the material groove are provided with side plate buffering material pockets; the back plate outside the material groove is provided with a material receiving groove.
The inclination angle between a multi-stage trapezoid formed by a plurality of blanking pockets in the trough and the bottom plate is 40-45 degrees.
And a plurality of blanking pockets, a back plate buffering pocket and a side plate buffering pocket inside the trough are cast into a whole with the trough through casting materials.
And a reinforcing rib is arranged between the material receiving groove and the back plate.
The utility model has the advantages that: the production process requirement is met, the abrasion resistance and the impact resistance are realized, the service life is as long as more than two years, the sintered ore can smoothly fall to a single-roll crusher, and the operation rate of a sintering machine is improved.

Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached drawings 1-5, the tail guide chute of the sintering machine comprises a material chute 5 and a base 6, wherein the material chute 5 is fixed on the base 6; the material groove 5 is formed by combining a back plate 12, two side plates 13 and a bottom plate 14, a plurality of blanking pockets 9 are sequentially arranged in the material groove 5 from top to bottom, the blanking pockets 9 form a multi-stage trapezoid, a back plate buffer pocket 10 is arranged on the back plate 12 in the material groove 5, and a side plate buffer pocket 11 is arranged on the side plate 13 in the material groove 5; the back plate 12 outside the material groove 5 is provided with a material receiving groove 7.
Referring to fig. 1-4, the utility model discloses a sintering machine tail baffle box 3 comprises silo 5, base 6 and castable 8, and wherein silo 5 is formed by backplate 12, two curb plates 13, the combination of bottom plate 14, and base 6 is fixed with sword handle shape steel sheet, prevents that silo 5 from shifting in the sinter unloading impact process.
A plurality of blanking bags 9 are manufactured in the trough 5, the blanking bags 9 form a multi-stage trapezoid, and the inclination angle between the multi-stage trapezoid and the bottom plate 14 is 40-45 degrees. The blanking pocket 9 is made of GY-3 high-strength ceramic wear-resistant material and is integrally cast, the material is quick-setting wear-resistant material, the bonding force is strong, the overall performance is good, when the blanking pocket is used for a period of time and the local part needs to be repaired, the part is only required to be removed and then is cast, and then the blanking pocket is baked for a short time to put into production and use, so that the construction is convenient and the repair is simple.
And buffer material pockets are respectively welded on the back plate 12 and the two side plates 13 in the trough 5, and are also poured by using pouring materials, so that the impact abrasion of the sinter to the side surface and the back surface in the discharging process is avoided.
The material receiving groove 7 on the back plate 12 outside the material groove 5 is fixed through the inclined triangular tie bars and has the function of preventing the sinter from extruding and impacting the base to cause the base to be completely broken.
Fig. 5 is the usage state schematic diagram of the utility model, and the discharging trolley 2 pours the sinter onto the material guiding groove 3 along with the rotation of the tail star wheel 1 of the sintering machine, and finally rebounds to the crusher 4 to crush the sinter.
