Abstract

The utility model discloses a back-open unloading dustpan with a circular bottom and an arc door, which belongs to a dustpan for carrying coal. The dustpan is provided with a frame, which comprises an upper pan, a vertical pole and a below pan. The vertical pole is positioned between the upper pan and the below pan. A dustpan box is arranged in the frame. An unloading strobe is positioned in the below of the dustpan box. And a bending rail is arranged on a well bracket; the unloading strobe is provided with two lateral boards and is connected with a rotor cover; an arc board is positioned in the below of the device; and an unloading axis is arranged in the below of the arc board; an unloading trolley is arranged on both ends of the unloading axis; the bending rail is provided with a diagonal groove shaped railway; two linear railway are positioned on the upper end and the below end of the diagonal groove shaped railway respectively. When the dustpan runs to the bending rail, the unloading wheel enters the bending rail; the dustpan continues to run upwards, the unloading trolley runs with the track of the bending rail to backwards open the unloading strobe; after finishing the unloading, the dustpan runs downwards, the unloading trolley backs with the track of the bending rail to onwards close the unloading strobe. The device is characterized in simple structure, fast unloading speed and stable operation.

Description

Circular arc door curve trail load skip bucket at the bottom of the back open type

Technical field

The utility model relates to a kind of coal skip bucket of carrying, and circular arc door bend unloads skip bucket automatically at the bottom of a kind of back open type of more specifically saying so.

Background technology

At present, in the large-scale skip bucket more than 20 tons and 20 tons, outer power unloading manner is all adopted in its unloading, promptly adopts cylinder or hydraulic actuating cylinder to open the skip bucket gate, and its shortcoming is: the unloading stop time is long, equipment investment is big, fault is many, maintenance workload is big.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, unloading fast and safe reliability high carry the coal skip bucket.

The purpose of this utility model is achieved in that this skip bucket has a framework, and framework is made of last dish, column and lower wall, and column is between last dish and lower wall, and the bucket case places framework, in the bottom of bucket case the unloading gate is installed, and bend is installed on derrick.

The unloading gate has two side plates, and swivel sleeve is arranged at side plate top, and arc plate is arranged at the side plate bottom, and the unloading axle is arranged under the arc plate, and there is unloading roller at unloading axle two ends.

Bend has skew lines grooved track, at upper and lower two ends of skew lines grooved track one straight-line groove type track is arranged respectively, and straight line grooved track all is connected with skew lines grooved track by the camber track.

Beneficial effect: owing to adopt such scheme, when skip bucket ran to the bend position, the unloading roller of unloading gate bottom entered bend, and skip bucket continues upward movement, and unloading roller is pressed the bend orbiting motion, will unload gate and open backward; After the completion of discharge, skip bucket moves downward, and unloading roller returns by the bend rail, will unload gate and close forward, and this skip bucket is simple in structure, and unloading is quick, and operates steadily, and has reached the purpose of this utility model.

The specific embodiment

Embodiment: in Fig. 1: circular arc door bend unloads skip bucket automatically at the bottom of the open type of a kind of back, the top of last dish 1 is connected with steel-cable suspensioning device, two or four root posts 2 are installed in the both sides of last dish 1, and column 2 fixes by modes such as riveting, weldering or bolt and bucket case 3 and lower wall 6; In the bottom of bucket case 3 unloading gate 4 is installed, unloading gate 4 is connected with bucket case 3 by anchor shaft 5, and unloading gate 4 can rotate around anchor shaft 5.Simultaneously, two bends 7 are installed on derrick, when the skip bucket up-and-down movement, two unloading rollers on the unloading gate 4 move in bend 7, thereby open or close unloading gate 4, reach and finish discharged purpose.

In Fig. 2: bend has skew lines grooved track, at upper and lower two ends of skew lines grooved track one straight-line groove type track is arranged respectively, and straight line grooved track all is connected with skew lines grooved track by the camber track.Bend 7 is made up of base plate 13, right riser 14 and left riser 15, base plate 13 links with derrick, right riser 14 and left riser 15 are welded on more than the base plate and form groove, the segment of curve of right riser 14 and left riser 15 constitutes by two circular arcs that differ in size up and down and skew lines, can avoid the dead point, unloading pulley 12 is moved in groove steadily.

In Fig. 3, Fig. 4: unloading gate 4 mainly is made up of side plate 8, arc plate 9, axle sleeve 10, unloading axle 11 and unloading roller 12.Arc plate 9 is installed between biside plate 8, and the top of side plate 8 is equipped with two axle sleeves 10, and by axle sleeve 10, unloading gate 4 can rotate around anchor shaft 5; Unloading axle 11 is equipped with in the bottom of biside plate 8, and unloading roller 12 is installed in the two ends of unloading axle 11, when unloading roller 12 moves in bend 7, can drive gate 4 and open backward or close forward.
