Scraper conveyer is one of the main equipment for conveying coal in fully mechanized coal mining face, and the central trough of scraper conveyer is the fuselage component and material bearing mechanism of scraper machine, so the central trough of scraper machine also has an important effect on scraper machine.
We all know that the scraper conveyor is mainly composed of the nose, tail and fuselage. The main body of the scraper conveyor is the central trough. The performance of the scraper 105S07 central trough directly affects the service life of the scraper conveyor. The central trough of 105S07 bears the severe friction of coal, scraper and chain in the process of coal conveying. The middle trough of the scraper conveyer 105S07 is also the fulcrum of the hydraulic support moving in the fully mechanized coal face. Due to long time wear and tear, consumption is large, so scraper conveyor central trough is also the daily purchase of coal mine more scraper accessories.
Because the scraper conveyor has different types, such as light, heavy, super heavy points, so for the scraper conveyor trough structure requirements are also different, so that the scraper conveyor trough category is also divided into several, such as welding central trough, casting welding central trough and integral casting central trough; Open bottom middle slot and back bottom middle slot; Middle canal of single bedded ear and middle canal of double bedded ear, etc.
Although scraper conveyor 105S07 central trough structure is relatively simple, but it does not mean that it is not important in the scraper accessories, no matter the weight, no matter the size, scraper accessories have their own role and significance. So Henan Shuangzhi machinery has been all the same, no matter what scraper accessories pay attention to product quality, start from small details, so as to make the overall scraper conveyor normal operation.

The middle trough of the scraper conveyor is one of the key parts of the scraper conveyor, and it is the fuselage of the scraper conveyor. Only the volume and quality of the scraper conveyor occupies about 70% of the scraper conveyor machine. Scraper parts manufacturer Henan shuangzhi below for you to introduce the scraper middle trough.
As an important spare part of the scraper conveyor, the middle trough of the scraper is not only the bearing mechanism of the material and the scraper chain, but also the important fulcrum of the hydraulic support. Each scraper is generally equipped with more than 100 middle slots, the length of the middle slot is mainly 1.5m and 1.75m two types. Therefore, the service life of the scraper and the transport volume are largely determined by the service life of the middle slot.
The middle slot is mainly made of the groove side and the middle plate. The material is mainly 16Mn and ZG30SiMn2 of high manganese steel.
According to the different manufacturing technology of the middle slot, the middle slot can be divided into welding middle slot, casting middle slot and integral casting middle slot.
According to the different structure of the central trough, the central trough can be divided into the open bottom middle trough and the back end middle trough.
The middle groove can be divided into the middle groove of the single and the middle groove of the double.
The central trough of the scraper is in direct contact with the material, coal gangue and scraper chain, which is easy to be affected by it and will cause scraping and wear for a long time. The middle plate, bottom plate and groove top of the middle slot are the most prone to wear. The main wear forms are abrasive wear, fatigue wear, adhesive wear and corrosion wear.
Henan Shuangzhi, as a highly praised scraper conveyor accessories manufacturer in the industry, improves the abrasion resistance of the central slot of the scraper by adopting wear-resistant materials and optimizing the surface strengthening technology of the central slot.

Sprocket components and scraper chain as the important transmission configuration of scraper conveyor, if there is a fault, it may affect the normal operation of underground coal mining work. So how do you deal with such situations?
The sprocket components sometimes has the phenomenon of high temperature in the operation process, the cause may be the insufficient lubricating oil, or the damage of bearing and sprocket may cause the aggravation of friction, which makes the temperature rise. Then the solution is to oil the sprocket assembly, so that the amount of oil to the specified requirements, or replace the worn bearing, sprocket body to make a new replacement.
The scraper chain has the condition of jumping teeth at the sprocket assembly, which is caused by many factors, such as too loose scraper chain, twisted chain segment, unequal length or elongation of double-strand chain or different number of rings, as well as the influence of excessive scraper deformation. The correct treatment method is to adjust it: re-tensioning the scraper chain, re-install the twisted chain segment correctly, check the scraper chain length and elongation if unqualified, it should be adjusted and replaced, and must use the odd ring chain, and is to replace the seriously deformed scraper.
Inspect the daily maintenance of sprocket assembly and chain of scraper conveyer according to different conditions, deal with and solve the faults in time, reduce the influence of associated problems. Henan Shuangzhi production scraper transfer machine parts, crusher and reducer parts, etc. Welcome new and old customers to visit the factory.
The dumbbell pin plays an important role in the normal operation of the scraper conveyer as the connecting member between two adjacent chutes. Today the coal machine parts manufacturer Henan shuanzhi will introduce the dumbbell pin of scraper conveyer for you.
Scraper conveyor dumbbell pin shape is like "fitness dumbbell", the middle is thinner, thicker at both ends. The dumbbell pin jams the ends of the two adjacent middle slots by the thicker ends at each end and connects the two adjacent middle slots by the thin middle rod. In addition to the common dumbbell pins described above, there are two types of special shaped dumbbell pins - I-type dumbbell pins and day-type rings.
The stress condition of dumbbell pin is more complicated. In the process of hydraulic support moving the middle trough, the dumbbell pin will be pulled by the adjacent middle trough and subjected to shear stress because the adjacent chute is not synchronized.
The dumbbell pin of scraper conveyor is a vulnerable part, and the common fault is fracture. The first crack occurred in the neck of the dumbbell pin, mainly because the neck of the dumbbell pin is a region where stress concentration is relatively large. Under long-term working conditions, the dumbbell pin's neck crack growth area diffused to a certain extent, resulting in fatigue fracture, resulting in the fracture of the whole dumbbell pin.
Once the dumbbell pin is broken, it will cause the middle slot dislocation or off, the scraper chain is affected by it, easy to break the chain, the chain clip, from the chute off the phenomenon, affecting the scraper conveyor working surface production safety and normal production.
Above is the dumbbell pin on the scraper conveyer, do you know? The dumbbell pin of the scraper conveyer produced by Henan Shuangzhi is forged from the selected material of 40Cr, and the quality is comparable to that of the original products after multiple processes such as tempering and quenching. More scraper parts, transfer machine parts, hydraulic bracket parts related product models, product information, you are welcome to consult.

The planetary reducer is installed in the head and tail of the conveyor to adjust the working speed of the sprocket shaft set and the carrying capacity of the scraper chain, so as to suit the working needs of different design power and rotating speed of the scraper conveyor.
According to the different structural characteristics of the reducer, the use of different, its general classification is as follows:
1. According to the series of transmission, it is divided into single-stage reducer and multi-stage reducer
2. According to the type of transmission, it is divided into fixed-axis reducer and planetary reducer
3. According to the layout requirements of scraper conveyor, it can be divided into parallel layout type and vertical type
Scraper reducer is mainly used for planetary reducer. Compared with fixed-shaft gear transmission, planetary gear transmission has more compact structure, more stable transmission, larger transmission ratio of the same series, and better performance in bearing capacity. But because this kind of decelerator usually has three or four planetary wheels in the planetary frame design, its structure is more complex, the parts processing precision request is higher.
The main parts of scraper planetary reducer include one shaft assembly, two shaft assembly, three shaft assembly, output tie rod assembly, sun wheel, inner gear ring, box assembly, cooling device and lubrication system.
