In the finished pellet ore distribution chute, finished pellets cooled by a circular cooler are transported to a track ore distribution chute of a belt conveyor through the transportation of a plurality of belt conveyors, and are discharged to a finished ore discharge chute by moving the distribution chute through the track ore distribution chute. The movable track finished product distributing chute is positioned at the upper end of the finished product ore drawing chute. The finished pellets are 12mm-16mm in size and round in shape, the strength and hardness of the pellets are high, the pellets are in contact with the wall surface of a chute box body, the friction and scouring speed is high due to the inertia of the conveying of a belt conveyor in the process of unloading the pellets from the chute, the wall surface of the chute box body is severely worn, the pellets are frequently leaked, the pellets are scattered around the belt conveyor and the chute, the labor intensity of the leaked pellets is high, the operation time is long, and the daily production is influenced. Because the pellet mill is in a 24-hour continuous production mode, the pellet mill is not required to be stopped, the daily chute is damaged and can only be repaired for a small time to maintain production, the chute can be replaced after long-time production stoppage maintenance, and the service cycle of the chute is short. The problem is that the pellet distributing chute is often damaged, the material sprinkling is serious, the service cycle is short, and the maintenance cost is increased. Before transformation, the material distributing chute is often damaged, the material sprinkling is serious, the service period is short, the service period of the main body material distributing chute is about 18 months, and the service period of the split chute is about 8 months.

In the above scheme, the method further comprises:
the wall surfaces include left and right wall surfaces and an impacted opposing wall surface.
The plug-in connection is that a scraping plate jack is oppositely arranged between two wall surfaces and is obliquely arranged upwards.
The upward inclined arrangement of the scraping plate means that the inclined included angle between the scraping plate and the wall surface of the chute box body is 45 degrees.
The sliding door is characterized in that a door pin type access door is arranged on the wall surface where the scraping plate which is movably inserted is positioned, one side of the door pin type access door is connected with the wall surface of the sliding door through a welded hinge, a notch matched with a lock nose is arranged on the other side of the door pin type access door, a convex lock nose is arranged on the wall surface of the sliding door at the notch along the upper and lower intervals, and a lock hole for the wedge-shaped armature to be inserted from the upper part is arranged in the middle of the lock nose.
The utility model has the advantages that: 1. scraping plates are obliquely arranged at the positions of the chute, which are easy to wear, and when the chute is used for discharging, pellets can be hung on the scraping plates, and the pellets which are subsequently inclined collide and rub with the pellets in the scraping plates, so that the integrity of the wall of the chute box body is protected, and the service cycle of the finished chute is prolonged. 2. The door pin type access door, namely the chute access window, is added, so that the daily spot inspection and maintenance of spot inspection personnel and maintenance personnel are greatly facilitated. The important wearing parts adopt the bolt type scraping plate, so that the maintenance time is not required, the wearing is found at any time, the wearing parts are replaced at any time, and the common wearing parts are replaced during maintenance. 3. The service cycle of the scraping plate welded at the abrasion part of the common chute is 2-4 months, and each time the scraping plate is stopped for maintenance, the scraping plate is repaired and replaced according to the abrasion condition of the scraping plate in the chute, so that the abrasion of the chute is reduced, the service cycle of the chute is prolonged, and the expected service cycle is 3-4 years. 4. After the modification of the chute, the damage of the chute and the phenomenon of ore sprinkling are reduced, the service cycle of the material distributing chute is prolonged, unnecessary equipment shutdown is reduced, precious time is won for production, and the normal production of pellets is ensured.
Embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.
