use

One end of the Shandong Mining Machine 730 series variable line lifting groove is connected to the transition groove of the scraper conveyor and one end is linked to the middle groove of the scraper conveyor. Its role is to adjust the height of the transition groove to the height of the middle groove of the conveyor. The width of the headstock and the transition groove is adjusted to the width of the middle groove. Generally, the whole adjustment process is realized through a set of adjustments of the changing line and the raising groove.

structure

Shandong Mining Machinery 730 series variable line lifting trough is the body of the scraper conveyor, which is composed of the middle plate, the trough, the sealing bottom plate, the rail seat and the connecting plate.

There are two types of lifting slots: left lifting slot and right connecting slot. They are used to connect the nose, the tail transition slot and the middle section respectively, and play a further transition role to make the nose to the middle section transition more smoothly. It is an elongated special rack to facilitate the unit to walk in place when it reaches the nose or tail. The structures of the two types of lifting grooves are similar, except that their lifting directions are opposite. Both sides of the connecting groove are convex edges, so that the recess of the middle groove and the recess of the transition groove of the tail are connected.

Material

Middle plate: 45 steel

Groove help: 30SiMn

Advantages: The impact resistance is higher than ordinary steel plates, the average hardness is higher, the friction coefficient is low, the acid and alkali resistance and salt water corrosion resistance are high, the running resistance and noise are low, and it is not easy to deform after being stressed.

Craft

V method casting process (groove), sand casting, welding process.

National quality management system certification GB / T19001 / ISO9001: 2015 standard.

We can customize the processing according to the drawing number or drawing provided by the customer's central slot.

Advantages of the V method casting process: 1. The casting has good formability, which is conducive to the formation of products with clear contours and high surface finish; 2. The casting has a dense structure and good mechanical properties; 3. The casting has high dimensional accuracy and small casting machining margin; 4. The internal and external pressure difference of the sand mold is that the hardness of each part of the sand mold is uniform and high (more than 85); 5. The sand box is easy to mold, and the draft angle is small (0 ~ -1 °); 6. The thermal effect in the metal liquid The cavity is not easy to be deformed. 7. During the pouring, because the sand box is kept in a vacuum state, it is conducive to filling the cavity with metal liquid.
