Abstract
The utility model pertain to mechanical field of a coal mine machine and relates to a device that makes coal lumps creeping to prevent coal lumps breaking when coals are delivered, transferred and loaded, which comprises a receiving hopper, a chute, a hydrostatic pressure pushing rod, a travel switch and a relative control circuit. An ultrasonic probe is arranged over the receiving hopper, a vibrator is arranged on the chute, a flashboard is arranged on the bottom of the chute and flashboard is connected with the hydrostatic pressure pushing rod; the utility model adopts the ultrasonic probe to detect positions of lump coals, the lump coals move downwards by creeping motion along the chute, the discharge flow of lump coals is controlled by the flashboard driven by the hydrostatic pressure pushing rod to balance the receiving and discharge flow, which reduces the relative falls of lump coals, effectively prevents lump coals breaking, increases output capacity of lump coals and improves economic benefits. The utility model is characterized in a simple structure, higher automation and simple operation.
Description
Technical field
The utility model belongs to the coal mine machinery field, relates to a kind of coal that is used for and carries the device that makes the lump coal wriggling prevent lump coal breaking when reprinting.
Background technology
In the coal washing operation, when coal cinder was reprinted another load-transfer device or other device from a load-transfer device, because drop is bigger up and down, lump coal was when falling, flow velocity is fast, and flow is big, strikes on the coal barrel, easily causes lump coal breaking, influence the lump coal quality, the lump coal grade reduces, and makes economic benefit impaired.
Summary of the invention
The purpose of this utility model is to provide a kind of may command to carry transfer point lump coal flow drop, effectively reduces the transfer point lump coal wriggling anti-crushing device of lump coal breaking.
The technical solution adopted in the utility model: a kind of conveying transfer point lump coal wriggling anti-crushing device, include hopper, chute, hydraulic push rod, travel switch and relevant control circuit, its material bin top is provided with ultrasonic probe, chute is provided with vibrator, the chute bottom is provided with plate, and plate connects hydraulic push rod.Ultrasonic probe is arranged at material bin position suitable for reading.
The utility model adopts ultrasonic probe to detect lump coal coal position, lump coal glides along the chute wriggling, plate control lump coal outflow by hydraulic push rod drives makes the equilibrium of turnover amount, has reduced the relative fall of lump coal, effectively prevent lump coal breaking, increase the output capacity of lump coal, increase economic efficiency, the utility model is simple in structure, the degree of automation height, easy and simple to handle.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
See also shown in Figure 1, a kind of conveying transfer point lump coal wriggling anti-crushing device, mainly be by material bin 1, ultrasonic probe 2, chute 3, vibrator 4, motor 5, hydraulic push rod 6, plate 7, travel switch 8 grades and existing relevant control circuit thereof constitute, its ultrasonic probe 2 is a prior art, be installed in material bin 1 top, the super sonic A that produces, B, C, D acts on chute 3 positions suitable for reading, chute 3 bottoms are provided with plate 7, plate 7 connects hydraulic push rod 6, and hydraulic push rod 6 is a prior art, is driven by motor 5, travel switch 8 control plates 7 crank motions, chute 3 is provided with vibrator 4, and vibrator 4 is a prior art, selects plate vibrator for use.
Principle of work of the present utility model: when lump coal when conveyer upper conveyor belt 10 enters hopper 1, ultrasonic probe 2 detects the coal position, hydraulic push rod 6 drives plate 7 control lump coal discharges, when lump coal inbound traffics out of reach D position, the plate 7 of chute 3 bottoms is closed, when the coal position rose to the C position, plate 7 was opened half under the effect of hydraulic push rod 6, when the coal position rises to the B position, plate 7 is all opened, when the coal position rises to the A position,, illustrate in the chute 3 and stop up if continue to raise in the coal position, at this moment under interlock circuit control, vibrator 4 begins vibration, has solved blockage problem, and lump coal enters lower conveyor belt 9 along chute 3.Since keep lump coal coal position to be not less than the C position all the time, the equilibrium of turnover amount, and adopt wriggling to glide, and so just reduced the relative fall of lump coal, solved the broken problem of coal, also can reduce the noise and the dust in coal washing workshop.
Claims (2)
