Overview of reciprocating feeder

Reciprocating feeder is suitable for transferring and transporting bulk materials such as mine, mine, coal preparation plant, medium station, coal transporting workshop, port bulk material wharf, etc. It can transfer bulk materials uniformly through the silo to tape machine or other screening equipment and storage device. Realize the uniform feeding of bulk materials such as ore, sand coal and grain. The feeding trough of this series of feeders is reciprocated in a straight line by a driving device through a crank connecting rod device. When the feed tank moves forward, the material will be removed by the action of inertia force and friction force. At this time, the material in the hopper will fall down, so that it cannot be discharged in the front. The transmission device of this series feeder is suspended, which can be directly arranged under the hopper for easy installation.

Reciprocating feeder has the advantages of uniform feeding, stable feeding, adjustable feeding amount, small shape height, simple structure, convenient adjustment and installation, reliable operation and long service life.

Main structure and working principle of reciprocating feeder

This series feeder consists of chassis, transmission platform, funnel, gate, connecting rod and the roller and so on its transmission principle: when the motor start, the elastic coupling, gear reducer, crank connecting rod device drag tilting chassis on the roller as a straight line reciprocating movement, the material evenly discharged to the transport machinery, or other screening equipment. This feeder has a variety of combination types, such as funnel, valve with adjustment and funnel, gate without adjustment, etc. When conveying hard materials, consider adding a liner at the bottom of the tank.

Method for adjusting feed quantity of reciprocating feeder

The feed quantity can be controlled by changing the opening of the sector valve.

Installation and use of reciprocating feeder

1. Reciprocating feeder is fixed and installed under the opening of the storage bin. Before installation, the horizontal position should be determined and the rack and the opening should be bolted.

2. After the feeder is installed and in place, start the motor without load to make the feeder run without load. If no abnormal phenomenon is found within 20 minutes during empty operation, stop to check the temperature rise of the motor and reducer. If normal, check again and tighten the relevant bolts and nuts, then restart and slowly open the bunker to make coal flow into the feeder from small to large, so that the feeder can be put into normal operation.

3. When adjusting the productivity according to unloading requirements, pull out the boat at the crank position, loosen the nut, turn the position of the crank shell "1, 2, 3, 4" and fix it, insert the pin shaft, connect the crank and crank case, tighten the pin shaft and nut, and start after adjustment.

Overhaul and maintenance of reciprocating feeder

1. Before the feeding machine is transported, enough raw coal shall be stored in the bunker to avoid direct impact on the floor when the coal is loaded into the bunker.

2. After monthly continuous work, check whether the parts are loose and other abnormal phenomena. If any abnormal phenomenon occurs, repair immediately.

3. The bottom liner in direct contact with coal shall be repaired or replaced with a thickness greater than half of the original thickness.

4. All rotating parts shall be oiled once a month and checked once a quarter to observe the damage degree of bearings and seals and replace them in time when problems are found.

5. Maintenance of major components:

(1) Reduction gear

Check every six months, and clean or replace the lubricating oil on the rolling bearings and housing.

(2) Electric motors

According to the motor maintenance requirements.

Users' attention: lubricate moving parts regularly, check the running condition of each part, find out the reason in time and deal with the abnormal situation, and notify the manufacturer to deal with it when necessary; Close the gate when the empty warehouse is being repaired.

Failure handling of reciprocating feeder

Malfunction: Abnormal sound

Reason analysis: the joints are loose

Method of elimination: Check and strengthen each connection

Failure phenomenon: heat of moving parts

Cause analysis: bearing lack of lubricating oil or bearing damage

Elimination method: timely oiling or replacement of bearings

Failure phenomenon: the roller is stuck and cannot move

Cause analysis: Bearing damage

Method of elimination: replace spare roller assembly or disassemble assembly to replace bearing

Ordering instructions for reciprocating feeder

1. The feeder has a variety of types combined with funnel and without funnel and with regulating gate and without regulating gate, such as with funnel and with regulating gate; With funnel, without regulating gate. The user should explain when ordering.

2. The voltage of this series of feeders is 380V and 660V. Please make sure the voltage standard and whether there is explosion-proof requirement.

3. There are two types of equipment installation: floor type and hanging type, and there are two types of structure: ordinary type and anti-channeling type. Please do not carefully consider when selecting the type; The equipment foundation bolts and hanging foundation are generally provided by the user.

4. Due to the different actual conditions on site, it is suggested that when you choose and order the equipment models and specifications, you should describe your requirements in detail and fully communicate with relevant professional and technical personnel, so as to reduce the trouble.
