Abstract

The material feeder includes hopper with supporting frame, front passage with material stop with material stopping skirt plate in the lower part, material flow regulating baffle, suspending feeding unit in the bottom of the hopper and great tilt angle corrugated baffle conveyer. The present invention solves the problem of bin pressure and the material feeder is suitable for use in coal dock or coal yard.

Description

A kind of feeding device

Technical field

The present invention relates to a kind of feeding device that is used for the aliment materials flow.

Background technology

In order to be easy to control materials flow, reduce the wearing and tearing of material to conveying machinery, more satisfactory feeding device must be furnished with feeder.The form of feeding device has three kinds at present, first kind is highly unrestricted large-scale feeding device, mainly accept the supplied materials of equipment such as ship unloaders, door machine, bridge crane car, stocker, because it is highly unrestricted, it is very big that hopper can be arranged, and have sufficient height to design in the feed hopper key-" the storehouse neck " that reduces " storehouse pressure ".This " storehouse neck " is positioned at the top of feeder, and material has almost all passed to the storehouse neck with pressure, thereby feeder only bears its intrinsic material load.Second kind is the small-sized feeding device of height-limited system, the main supplied materials of accepting various loader, because loader feed height is limited, the width of hopper is big again, and (the feed height can not surpass 3000mm usually, the width of hopper can not be less than 3600mm), if still adopt the version that adds storehouse neck and feeder, because insufficient height must be arranged in the part-structure and the conveying machinery afterbody of feeding device bottom underground.Like this, the one, strengthened the civil engineering work capacity; The 2nd, maintenance and repair are difficulty comparatively; The 3rd, must the designing and arranging water system.The third is still the small-sized feeding device of accepting the loader supplied materials, because insufficient height, can not design storehouse neck and feeder, just simply will expect mouthful to receive in the width of conveyer belt, utilize belt to lean on friction that material is taken away, its shortcoming is to be not easy to control materials flow, be highly susceptible to taking place stifled bucket phenomenon, conventional way is to increase by one in hopper closing in place operablely to pull moving reinforcing bar, stir the material of the inside during stifled the bucket, it is flowed fall, this way is very backward, and is easy to the belt that weares and teares.

Summary of the invention

The object of the present invention is to provide a kind of the utilization in the limited altitude range, on the basis that does not increase the storehouse neck,, efficiently solve the storehouse and press problem by eliminating the materials flow pressure apparatus.

For achieving the above object, technical solution of the present invention is finished like this: a kind of feeding device, it installs a stock stop and materials flow controllable register respectively by reaching front passage in the hopper, the body bottom of this stock stop has intilted backgauge skirtboard, be provided with the suspension type charging gear in the bottom of hopper, the delivery port of its suspension type charging gear is constituted corresponding to high spud angle corrugated sidewall conveyer.

The effect that feeding device of the present invention has is: in limited height, solved " storehouse pressure " problem preferably with easy method.By the passage that osed top stock stop and hopper front end are set in the hopper materials flow controllable register has been installed, reduced hopper front end inlet amount, and can control the feeding coal of feeder, reduce " storehouse pressure " and solid accumulation phenomenon to greatest extent, thereby guaranteed the normal operation of material fluidity and feeder.

Description of drawings

Fig. 1 is the structural representation of feeding device.

Fig. 2 is the right elevation of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is described further and illustrates, provided feeding device by Fig. 1,2, it comprises bracing frame 1 and goes up the hopper of installing 5, the high spud angle corrugated sidewall conveyer of installing at the side of its bracing frame 19, press for reducing the storehouse, and in hopper 5, be provided with stock stop 6, promptly have the flow direction that intilted backgauge skirtboard 7 is controlled material by stock stop 6 body bottoms, the materials flow pressure of all directions can be resisted, the drop point of material can be redistributed again.Be provided with the suspension type charging gear in the bottom of hopper 5, this suspension type charging gear is by a feeder trough 3, flexibly connected hard-wired actuator 2 in its bottom, formed, and be installed in the groove of side of hopper 5 by the spring 4 that feeder trough 3 bilateral symmetry are provided with.The delivery port of suspension type charging gear is at the passage same position place of hopper 5, and make the upper end of its delivery port exit corresponding to inclination angle corrugated sidewall conveyer 9, make material pass to high spud angle corrugated sidewall conveyer 9 by the suspension type charging gear, avoid the contacting of material of conveyer 9 and hopper 5 closing ins place, and caused the wearing and tearing of belt.The materials flow controllable register 8 of hour flow that is used to control the suspension type charging gear has been installed on the porthole that is positioned at hopper 5 front ends.The both sides of materials flow controllable register 8 are provided with the adjusting dowel bolt, install and to cooperate with the frid that has hole slot is installed on hopper 5 front passage, make bolt see through hole slot, utilize bolt to act on to make on the frid to regulate plate washer 8 and locate, with the openings of sizes of selector channel.

Above-mentioned stock stop 6 is the pressure of minimizing materials flow, and stock stop 6 is made bullet, and an end wherein is installed on hopper 5 walls, and another sidewall that the other end has bevelled end face and hopper 5 leaves a segment distance.

Claims

1, a kind of feeding device, comprise bracing frame and go up the hopper of installing, and conveyer, it is characterized in that, it installs a stock stop (6) and materials flow controllable register (8) respectively by reaching front passage in the hopper (5), the body bottom of this stock stop (6) has intilted backgauge skirtboard (7), is provided with the suspension type charging gear in the bottom of hopper (5), and the delivery port of suspension type feed dress is constituted corresponding to high spud angle corrugated sidewall conveyer (9).

2, by the described feeding device of claim 1, it is characterized in that described stock stop (6) is a bullet, has the bevelled end face.

By the described feeding device of claim 1, it is characterized in that 3, described suspension type charging gear materials flow is regulated by feeder trough (3), be connected with actuator (2), and form by the pendulum spring (4) that feeder trough (3) bilateral symmetry is provided with in its bottom.
