The specific embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.

Embodiment

A kind of material anti-crushing transfer point system comprises hopper 2, main chute 3, first band feeder 4; Described hopper 2 is positioned at vibrating grizzly 1 below and is used for receiving, storing the material that vibrating grizzly 1 is sent here; The top of described main chute 3 is connected with the mouth of described hopper 2; The bottom of described main chute 3 is provided with first band feeder 4, first band feeder 4 is a kind of transmitting bulk material devices that are widely used in the industries such as coal, metallurgy, building, chemical industry, it adopts the belt conveyer principle, and transmitting power is the combined type stepless speed regulating motor for speed reducer.

In above-described embodiment scheme, during system initialization, the bottom of described main chute 3 is positioned at the load-transfer device top of first band feeder 4; Material is in vibrating grizzly 1 is delivered to hopper 2, again through the load-transfer device of main chute 3 to first band feeder 4, because the bottom of main chute 3 is nearer apart from the load-transfer device of first band feeder 4, material can not overflow from main chute 3 bottom end openings, treat the full main chute 3 of material filling, and when reaching the assigned address of hopper 2, delivery speed by manual control first band feeder 4, make material at retractable chute 2 interior downward wrigglings, and slowly transport from the load-transfer device of first band feeder 4, reduce because the bad reaction that high drop brings to material.

Adopt in above-described embodiment scheme and manually be controlled to be the master,, comprise also be used to the electronic control module 5 of controlling described first band feeder 4 that described electronic control module 5 is electrically connected with described first band feeder 4 as the improvement of above-described embodiment scheme; Described hopper 2 is provided with the radar level gauge 6 for detection of described hopper 2 interior material quantities.

As the improvement of above-described embodiment scheme, be provided with frequency converter 7 between described electronic control module 5 and the described first band feeder 4, adjust the delivery speed of first band feeder 4 by frequency converter 7.

Improvement as above-described embodiment scheme, the mouth of described hopper 2 also is provided with bypass chute 8, and described bypass chute 8 is electrically connected with described electronic control module 5, and the effect of bypass chute 8 is to open when first band feeder 4 or electronic control module 5 break down, change coal stream, do not affect normal production.

By above-described embodiment scheme, can be with hopper 2 by highly being divided into A, B, C, D, E, F, 6 sections.Radar level gauge 6 continuously is transferred to electronic control module 5 to the coal bunker level indicator that collects, and when material was lower than the A point, first band feeder 4 was failure to actuate; When the coal position rose to the AB interval, first band feeder 4 was with lower frequency (such as 10Hz) automatic discharge; If the supplied materials amount more greatly then material can rise to the BC interval, first band feeder 4 is with higher frequency (such as 20Hz) automatic discharge; If the supplied materials amount very greatly then material can rise to the CD interval, first band feeder 4 is with higher frequency (such as 30Hz) automatic discharge; If the unusual large coal of supplied materials amount position rises to the DE interval, first band feeder 4 is with 40Hz frequency automatic discharge; If the unusual large coal of supplied materials amount position rises to the EF interval, first band feeder 4 is with 50Hz frequency automatic discharge, and when the coal position surpassed warning coal position, siren was also sent in the simultaneously outside combined aural and visual alarm flicker of the indicator lamp of electronic control module 5 flicker, and prompting is bought securities with all one's capital or stopped up; When material level was lower than the A point, first band feeder 4 quit work again.Along with the rising of coal position enters next same working process, such reciprocation cycle, material is all the time in 1.5 meters of hopper 2, main chute 3 interior material wrigglings glide, just greatly reduce the height of drop of material, reduced noise in the coal loading chute, airborne dust, to the impact of hopper 2 and belt, the service life of improving the equipment such as belt and chute when preventing coal crusher with hopper 2.

More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and field of application, in sum, this description should not be construed as restriction of the present utility model.
