Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, in particular to a side-discharge feeder with an automatically adjustable feeding chute. Background Art

[0002] Side discharge feeder is widely used in coal conveying system of thermal power plant, and also in material conveying system of coal mine, port, mining, metallurgy, food, coal chemical industry, dock, building materials and other industries. It is a special equipment for quantitative feeding, especially suitable for arrangement under coal hopper of power plant.

[0003] The feeding capacity of the side discharge feeder is mainly determined by the equipment amplitude and the shape of the curved trough. Generally, a frequency converter or a variable force wheel is used to adjust the vibration motor on the side discharge feeder to change the exciting force and adjust the feeding amount. The feeding capacity can be adjusted locally or remotely.

[0004] When the physical properties of the material change significantly, limited adjustments will be difficult to adapt to the changes and fail to meet the requirements of the feeder. This type of accident is mainly caused by sudden changes in the fluidity of the incoming material, such as when the material is transported by train and soaked in rain, or when the material is frozen due to low temperature. Summary of the invention

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a side-discharge feeder with an automatically adjustable feeding chute. The feeding chute is provided with a movable insert bar. When the push rod is started, the insert bar is extended into the feeding chute to cover the recessed part in the middle of the feeding chute. The feeding capacity of the side-discharge feeder is greatly improved and the locking capacity is reduced. It is used in the case of sudden reduction in material fluidity and can restore the normal feeding capacity.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a side-discharge feeder with an automatically adjustable feeding chute, comprising a side-discharge feeder body, a feeding chute, a push rod assembly and a movable insert strip, wherein a feeding chute is arranged in the side-discharge feeder body, and a push rod assembly is arranged on the outside of the equipment of the feeding chute, and a movable insert strip is connected to the driving end of the push rod assembly, and the movable insert strip comprises a plurality of cylindrical insert rods arranged side by side, and a row of through holes is provided in the middle recessed part of the feeding chute, and the cylindrical insert rod of the movable insert strip can move back and forth in the through hole through the driving end of the push rod assembly.

[0007] In the above technical solution, the push rod assembly is provided with multiple ones, the width of the movable inserting strip on a single push rod assembly is not greater than 1m, the spacing between the cylindrical inserting rods is 30-50mm, and the diameter of a single cylindrical inserting rod is 80-120mm.

[0008] In the above technical solution, the front end of the cylindrical insertion rod is in a pointed cone shape.

[0009] In the above technical solution, the push rod assembly is obliquely connected to the feeding body by bolts, and the angle between the movable insert on the push rod assembly and the horizontal plane is not less than 45°.

[0010] In the above technical solution, the diameter of the through hole is larger than the diameter of the cylindrical insertion rod, and the difference between the two is not less than 5 mm.

[0011] In the above technical solution, the plurality of push rod assemblies on the same side of the feeding chute are all connected to the same hydraulic station, and the control of the hydraulic station is connected to the control system of the side discharge feeder.

[0012] The beneficial effect of the utility model is that when the fluidity of the material suddenly deteriorates or other reasons cause the side discharge feeder to be blocked, the function of the side discharge feeder can be changed through the push rod assembly and the movable insert strip to make the locking ability invalid, so that the blockage can be quickly eliminated without manual operation after stopping the machine; it can also be conveniently and quickly restored to the original state.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 7The side-discharge feeder with automatic adjustment of the feeding chute shown in the figure comprises a side-discharge feeder body 1, a feeding chute 2, a push rod assembly 3 and a movable insert bar 4. The side-discharge feeder body 1 is provided with a feeding chute 2, and the feeding chute 2 is provided with a push rod assembly 3 on the outside of the equipment. The driving end of the push rod assembly 3 is connected to the movable insert bar 4, and the movable insert bar 4 comprises a plurality of cylindrical insert rods arranged side by side. A row of through holes 5 is provided in the middle recessed part of the feeding chute 2, and the cylindrical insert rods of the movable insert bar 4 can move back and forth in the through holes 5 through the driving end of the push rod assembly 3.

[0023] In the above technical solution, the push rod assembly 3 is provided with multiple movable inserts 4 on a single push rod assembly, the width of the movable inserts 4 is not greater than 1m, the spacing between the cylindrical inserts is 30-50mm, and the diameter of a single cylindrical insert is 80-120mm. The width of the movable inserts 4 is not greater than 1m, which reduces the driving force of the driving end of the push rod assembly 3. The spacing between the cylindrical inserts is 30-50mm. Too large or too small spacing is not conducive to the flow of materials, and the diameter of the cylindrical insert is too small and easy to deform, and too large diameter causes the material capacity to increase, which is not conducive to the flow of materials.

[0024] In the above technical solution, the front end of the cylindrical insertion rod is a pointed cone, which facilitates the push rod assembly 3 to insert the movable insertion bar 4 into the material.

[0025] In the above technical solution, the push rod assembly 3 is connected to the side discharge feeder body 1 by bolts, and the angle between the movable insert 4 on the push rod assembly 3 and the horizontal plane is not less than 45 degrees. If the angle between the movable insert 4 and the horizontal plane is too small, it is easy to block the downward flow of materials.

[0026] In the above technical solution, the diameter of the through hole 5 is slightly larger than the diameter of the cylindrical rod, and the gap between the two is about 5 mm. If the gap between the through hole 5 and the cylindrical rod is too large, the material will easily leak out, and if it is too small, the cylindrical rod will be easily stuck.

[0027] In the above technical solution, the push rod assemblies on the same side of the feed chute are connected to the same hydraulic station, and the control of the hydraulic station is connected to the control system of the side discharge feeder. The control system controls the push rod assemblies to achieve automatic operation.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
