Abstract

The utility model relates to a discharge hopper, aiming at solving the problem that the discharge hopper of the existing belt conveyor is frequently damaged since the discharge hopper is impacted and abraded with a material. The liner type discharge hopper of the belt conveyor comprises an upper charging barrel and a lower chute, wherein a box type structure which is protrude from the outer side of a barrel body is arranged at the position on the charging barrel for carrying the material, or the wall of the barrel at the position for carrying the material is arranged to be vertical to the bottom surface of the charging barrel. The inclined surface of the chute for carrying the material is further provided with a box type structure which is protruded out of the chute, the bottom of the box type structure is split, and the bottom of the box is supported on the ground. The box type structure or a space which forms between the wall of the barrel and the bottom surface of the charging barrel naturally forms a material liner, and the material liner can not be abraded and can be automatically filled and compensated, so that the discharge hopper preferably solves the problem that the existing discharge hopper is frequently damaged.

Description

Belt conveyer liner type discharge funnel

Technical field

The utility model relates to belt conveyer, specifically is the discharge funnel that uses on the belt conveyer.

Background technology

All use belt conveyer in places such as the numerous mine of China, coal jetty, cement mill, building stones processing spaces, realized the adhesive tape transportationization.But in use, the discharge funnel of conventional (tradition) comprises top barrel 1 and the bottom chute 2 that communicates, unloading roller 9 is contained in a side direction barrel 1 interior convey materials of barrel 1, the opposite side lower end of barrel 1 is designed to barrel 1 inboard bevelled beveled barrel or installs the bevelled metal backing additional on barrel, inclined-plane or metal backing are the carriers as material, chute is usually designed to and horizontal surface angled (majority is 56 °), is also forming a carrier on the chute with on inclined-plane and the corresponding position of metal backing like this.More than said carrier under the wearing and tearing of material, impacting; often occur that discharge funnel snaps, problem such as worn out; one or two week of severe patient safeguards once; thereby maintenance cost is increased greatly; greatly also increased labor strength because of maintenance simultaneously, also production has been caused influence because of shutting down maintenance.Especially in the colliery, present most mines use caving coal coal-mining methods, and the bulk spoil is many, and present in addition coal mine output is all bigger, and conventional funnel is the needs of incompatibility large conveying quantity and scene reality, make the discharge funnel well damage.

As mentioned above, the frequent breakage of discharge funnel is perplexing the user always, never is well solved, and it is well to solve wearing and tearing, the shock problem of material to discharge funnel that there is the basic reason of the problems referred to above in conventional at present discharge funnel.Therefore needs further carry out analytical investigation to the operating condition of discharge funnel, adopt more scientific methods, solve this contradiction.

Summary of the invention

The problem of frequent breakage in order to solve existing belt conveyer discharge funnel and material impact, wearing and tearing, the utility model provides a kind of belt conveyer liner type discharge funnel.

Address the above problem, the technical solution adopted in the utility model is: a kind of belt conveyer liner type discharge funnel, comprise top barrel and bottom chute, the position of accepting material on the barrel is provided with one to the outstanding case structure in the stack shell outside, or the barrel that the receiver material level is put is set to vertical with the barrel bottom surface.The material that is introduced into barrel forms the material liner in case structure or at the place, space of vertical barrel and the formation of barrel bottom surface nature, form the work operating mode that material is broken material, has eliminated wearing and tearing, the impact of material to metal backing (or barrel).

The inclined-plane of accepting material on the chute also is provided with one to the outstanding case structure in the chute outside.Also can be filled into material naturally at this case structure and form the material liner.Be set to split typely at the bottom of the case of described case structure, be supported in ground at the bottom of the case, material is delivered on the ground at the bottom of split type case the downward impulsive force of chute base plate.

The utlity model has following beneficial effect: the utility model has successfully solved in the existing belt conveyer discharge funnel technology can not fine solution discharge funnel and material impact, wearing and tearing and the problem of frequent breakage.Because the material liner is not feared wearing and tearing and can be filled compensation automatically, this scheme had never been carried out any maintenance since on probation, facts have proved that this method has engineering value of service and promotional value.

Among the figure, the 1-barrel; The 2-chute; The 3-barrel; 4-barrel bottom surface; At the bottom of the 5-case; The 6-pedestal; 7-material liner; The 8-I-beam section, the 9-unloading roller.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be specified.

A kind of belt conveyer liner type discharge funnel described in the utility model, comprise top barrel 1 and bottom chute 2, the position of accepting material on the barrel 1 is provided with one to the outstanding case structure (as shown in Figure 1) in the stack shell outside, or the barrel 3 that the receiver material level is put is set to and barrel bottom surface 4 vertical (as shown in Figure 2).

The utility model is with the barrel of accepting material (or metal backing) cancellation of conventional discharge funnel front side, be designed to box bin stock structure, material is with its material liner 7 that is full of the back and forms a natural inclined plane, thereby the work operating mode of logistics and discharge funnel is that material is broken material, eliminated logistics to the wearing and tearing of metal backing (or barrel), impact the problem that causes frequent breakage.In the actual use in colliery, also observe, because the friction coefficient between coal and the coal is big, the coal liner has pooling feature in addition, after coal is wandered the coal liner, the phenomenon that the moment stop is arranged, follow-up coal stream is washed it open again, and the coal stream of being washed open slowly flows to both sides in an orderly manner along the material pad surfaces, and then drops to lentamente on the following chute 2.Because coal flows down the reduction of speed degree and slows down, reduced of the impact of coal stream to discharge funnel lower metal chute 2 base plates, having eliminated original coal stream is to impact to disperse in funnel, coal stream four phenomenons of penetrating of splashing.

As shown in Figure 1, 2, accept on the chute 2 and also be provided with one on the inclined-plane of material to the outstanding case structure in chute 2 outsides.5 are set to split typely at the bottom of the case of described case structure, and 5 are supported in pedestal 6 at the bottom of the case.

The discharging point place of lower metal chute base plate also is designed to box bin stock structure, but makes at the bottom of the case split type (also claiming live bottom type), be supported on the ground (or other bases) at the bottom of with split type case with I-beam section 8 members such as grade.Its function is: the one, form material liner 7, and eliminated the impact wear of material to metal chute 2 base plates; The 2nd, material is delivered on the ground at the bottom of split type case the downward impulsive force of chute 2 base plates, make the whole discharge funnel not be subjected to material basically, thereby eliminated material problems such as snapping of causing of the impact of funnel and bottom chute 2, distortion to its downward application force that causes.
