3. 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

Sprocket assembly is composed of sprocket and connecting roller. It is an important part of scraper conveyor, and it is also the most torque part of conveyor. Therefore, in the process of purchasing sprocket shaft group, many problems should be considered, and we must be very careful. Only in this way can we choose high-quality sprocket shaft group, prolong the service life of sprocket shaft group, and improve work efficiency, otherwise, In the use of the process is prone to accidents, resulting in labor and money, so what should be paid attention to in the process of purchasing sprocket shaft group? What is the price of sprocket shaft group

what problems should be paid attention to in the process of purchasing sprocket shaft group:

with the development of coal machinery and the national rectification and merger of small and medium-sized coal mines, large-scale fully mechanized mining equipment is more and more widely used in coal mines With the development of heavy-ty scraper conveyor, there are more and more types of scraper conveyor, and the models proced by major coal machine manufacturers are also different. As the main vulnerable parts of scraper conveyor, sprocket shaft group is not universal, which makes it difficult to determine when purchasing. So what problems should be paid attention to when purchasing sprocket shaft group? We summarize the following aspects

First, the main engine manufacturer of sprocket shaft group. As there are many manufacturers of scraper conveyor, the sprocket shaft group of each manufacturer can not be used in general, so when purchasing, we must first determine which manufacturer of scraper conveyor is suitable for sprocket shaft group. At present, the most important domestic scraper conveyor manufacturers are China Coal Zhangjiakou coal machinery plant, Ningxia Tiandi Benniu, Shandong mining machinery, Shanxi coal machinery plant and Zheng coal machinery

Second, the determination of drawing number of sprocket shaft group. Even for the same scraper conveyor manufacturer, the sprocket shaft group applicable to the same scraper conveyor model may not be the same. Therefore, it is necessary to determine the drawing number of the sprocket shaft group. Each sprocket shaft group has only one set of drawings. As long as you find the drawing number of the sprocket shaft group and have the corresponding drawings, you can ensure that the sprocket shaft group proced will not make mistakes

Third, the material selection of sprocket shaft group. Due to the increasing power and transportation volume of scraper conveyor, there are great requirements for the toughness and strength of sprocket shaft group. If the material selection is not appropriate, the sprocket shaft group will be prone to accidents in the use process, affecting the proction progress, and even safety accidents. At present, the commonly used materials are 42CrMo and 45crnimnmu. When selecting, the appropriate materials should be selected according to the transportation volume

Fourthly, the manufacturing process of sprocket shaft group. Due to the high requirements for the toughness and strength of the sprocket shaft group, the manufacturing process can not be careless. At present, the manufacturing process of the sprocket shaft group mainly includes forging, casting and welding. Small ordinary mining scraper conveyor can choose casting and welding sprocket shaft group. For large fully mechanized sprocket shaft group, in order to ensure its performance requirements, only forging sprocket shaft group can be selected, and heat treatment, quenching and tempering and other processes can be carried out

when purchasing the sprocket shaft group, we should pay attention to the above aspects. Basically, the sprocket shaft group can basically meet the performance required by the current scraper conveyor, but there is another point to pay attention to, that is, when the scraper conveyor is running, we must pay attention to the wear of the sprocket shaft group at any time to avoid accidents

the above is about the problems that should be paid attention to in the process of purchasing sprocket shaft group and the price introction of sprocket shaft group manufacturer, In the purchase of sprocket shaft group must be very careful, understand all the situation before making a decision, and in the purchase can not be greedy for small cheap Oh, to buy high-quality procts is the king. At the same time, when using the sprocket shaft group, you should often check the wear of the sprocket shaft group and take preventive measures to avoid accidents. I hope the above contents can help you

9. This depends on the performance of your authorities. Generally, the score is above 13, and the proficiency level is generally over 200. If you play a game, it will be about 100, and the poor performance will be reced.

10. You can first let the motor run at no load to measure whether the current is normal, such as the normal scraper is improperly adjusted to cause overload. If it is abnormal, it is motor fault. Check whether the motor bearing or electrical appliances are damaged.
