Deflecting slot of middle slot of scraper of Shandong mining mac

1. The main structure and components of various types of scraper conveyor are basically the same, which is composed of head, middle part and tail part. In addition, there are hydraulic jack device for pushing conveyor and chain tightening device for chain tightening. The head part is composed of head frame, motor, hydraulic coupling, recer and sprocket. The middle part is composed of transition groove, middle groove, chain and scraper. The tail part is a device for scraper chain to return. The tail of heavy-ty scraper conveyor, like the head, is also equipped with power transmission device. It is called upper head and lower head from the installation position.

2. I'm not sure what questions you want to ask about the middle trough. I'll summarize some points about the middle trough
I. matters needing attention in general layout of cast stone scraper conveyor with steel structure box are as follows:

for conveyors with B = 600mm, 800mm and 1000mm, there are two kinds of H values of head wheel center: 640mm and 440mm; B = 1200mm, 1400mm, only h = 640mm
when h = 640mm, H1 = 990mm, h2 = 1300mm, H3 = 330mm; When h = 440mm, H1, H2 and H3 are reced by 200 mm, and the maximum power is limited to no more than 18.5 kW, and only manual gate can be used without double layer transportation
the unloading holes must be reserved on the floor of the head part and the tail part
the L value of type selection length should be an integral multiple of 500mm
the general drawing must indicate the gate opening position size L2 or L1
the position of the bracket in the middle groove is decided by the user, but it should not collide with the stiffeners on the middle groove
there is a 30mm cement platform between the transmission frame, head frame, tail frame, middle slot bracket and the floor; All kinds of gates and chutes adopt embedded steel plates, which are fixed by spot welding after installation, without adding 30mm cement platform
the distance between the edge of feeding chute and the center of tail wheel L3 ≥ 2m
when the chain is working, it should be in the pulling working state. If it must be in the pushing working state, the length of the pushing part should not be greater than 1 / 2 of L, otherwise, the shaft strength must be recalculated. The running direction of the upper or lower chain shall be indicated in the general drawing< According to the layout and structure of scraper conveyor chute, it can be divided into parallel type and overlapping type. According to the number and layout of chain, it can be divided into single chain, double chain, double center chain and three chain. The main structure and components of various types of scraper conveyor are basically the same, which is composed of head, middle part and tail part. In addition, there are hydraulic jack device for pushing conveyor and chain tightening device for chain tightening. The head part is composed of head frame, motor, hydraulic coupling, recer and sprocket. The middle part is composed of transition groove, middle groove, chain and scraper. The tail part is a device for scraper chain to return. The tail of heavy-ty scraper conveyor, like the head, is also equipped with power transmission device. It is called upper head and lower head from the installation position. The working principle of scraper conveyor is that the open chute is used as the bearing part of coal, gangue or materials, and the scraper is fixed on the chain (forming scraper chain) as the traction component. When the driving part of the machine head starts, the chain wheel on the head shaft of the belt conveyor rotates to make the scraper chain circulate, and the animal material moves along the chute until it is unloaded at the machine head. The scraper chain bypasses the chain wheel for stepless closed cycle operation to complete the conveying of materials

these two parts of content are also seen from a website. There is a website search on it. You can search in it http://www.yingda-jx.com/pt/one/46.html Embedded scraper: http://www.yingda-jx.com/pt/one/50.html

3. SGB620 / 55 scraper conveyor is suitable for blasting mining face in gently inclined medium thick coal seam, mining face in gently inclined medium thick coal seam, and coal transportation in middle roadway. Zmjt15
middle groove specification (L * w * h): 1500 * 620 * 180

4. The middle trough of scraper is mainly used for scraper conveyor and transfer machine. It adopts high strength manganese plate, which is proced by automatic welding machine, and the welding position is flat without bulge. zmjt15

5. Scraper conveyor (also known as chute) is composed of chute head, chute tail, transition chute, middle chute (also known as chute), motor, recer, etc. there are 30 type chute and 40 type chute. The middle chute (chute) is the most used one, and increases with the extension of chute. The length of each chute is 1.5m. I wonder if it will help you

7. You can try kb968 wear-resistant welding wire, which is very suitable for the repair of the middle groove of scraper conveyor.
