With the accompanying drawing illustrated embodiment the present invention is done detailed description below.
The rotating shaft part that the present invention has bearing (2) and rotating shaft (3) to form, the crank section that crank (4) and pitman shaft (5) are formed also has dial (6), discharging rocking bar (7), weight part (8), totally five parts are formed (Fig. 1, Fig. 2, Fig. 3).
Rotating shaft partly is positioned at the top of hopper (1).Two bearings (2) symmetry is fixed on the middle upper portion of hopper (1) two side, is used for supporting shaft (3) and is installed in parts in the rotating shaft (3).Rotating shaft (3) level is installed in the two bearings (2), and bearing (2) (Fig. 1, Fig. 2) is in addition stretched out at the two ends of rotating shaft (3).
Crank section is positioned at an end of rotating shaft (3), and the inner end of crank (4) is fixed on the end of rotating shaft (3), and a pitman shaft (5) (Fig. 1, Fig. 2) parallel with rotating shaft (3) is equipped with in the outer end of crank (4).Crank section can rotate with rotating shaft (3), is used for opening and closing feed hopper bottom Dump gate (19).Width between centers between pitman shaft (5) and the rotating shaft (3) equals Dump gate (19) when being closed to full open, makes 1/2 of upper and lower displacement distance that the upper end of the connecting rod (21) that links to each other with pitman shaft (20) on the Dump gate (19) produces.
Dial (6) by steel are made is fixed on the other end of rotating shaft (3).Dial (6) is made up of chassis (9), pitman shaft (5) and two rectangle baffle plates (10) and (11).Chassis (9) is tabular fan-shaped, is fixed in the rotating shaft (3), and is concentric with rotating shaft (3) and vertical.A pitman shaft (5) also is housed, the axis in-line of two pitman shafts (5) on chassis (9).During use, the upper end of the connecting rod (21) that links to each other with pitman shaft (20) on the Dump gate (19) hangs on two pitman shafts (5).Baffle plate (10) and (11) are vertically fixed on the outer face of chassis (9), are positioned at axle sleeve (12) in addition, do not exceed the edge of chassis (9).The full swing angle of discharging rocking bar (7) between baffle plate (10) and (11) is 70 °～100 °, the axes intersect of the bisector of this angle and rotating shaft (3) also has 75 °～90 ° angle (Fig. 1, Fig. 2) with the plane that axis determined of pitman shaft (5) and rotating shaft (3).Dial (6) cooperates with discharging rocking bar (7), is used to control the opening and closing of Dump gate (19).
By the discharging rocking bar (7) that metallic material is made, be contained in the rotating shaft (3) near dial (6) outside.Discharging rocking bar (7) is made up of two rocking bars that are enclosed within the axle sleeve (12) in the rotating shaft (3) and be fixed on the axle sleeve (12).Short rocking bar (13) is positioned between two baffle plates (10) and (11) on the outer face of chassis (9), and the lower end of bar is fixed on the Wai Yuan top, inner end of axle sleeve (12), and the upper end of bar does not exceed the edge of chassis (9).The upper end of long rocking bar (14) is fixed on the Wai Yuan bottom, outer end of axle sleeve (12), and its length is 2/3～1 of hopper side wall width.Two rocking bar directions are opposite, and the longitudinal centerline of two rocking bars is crossed rotating shaft (3) center and perpendicular to the axis (Fig. 1, Fig. 2) of rotating shaft (3).Discharging rocking bar (7) can be stirred dial (6) by short rocking bar (13) and rotate when rotate (3) around the shaft, and drive rotating shaft (3) and the crank (4), weight (15) and the hammer stem (16) that are fixed in the rotating shaft (3) rotate simultaneously during dial (6) rotation.
Weight part (8) is made up of weight (15), hammer stem (16) and two weight bearings (17).Weight that metallic material is made (15) and hammer stem (16) are fixed as one, and the inner end of hammer stem (16) is vertically fixed near in the rotating shaft (3) of hopper side wall, and the outer end does not exceed hopper (1).When pitman shaft (5) with dial (6) and crank (4) when upwards forwarding vertex to, the horizontal surface of hammer stem (16) outer end and its underpart has 0 °～25 ° angle.Two weight bearings (17) are fixed on the both sides of rotating shaft (3), and on the bucket wall of weight (15) bottom, the bottom of two weight bearings (17) is a steel bracket, and top is one deck rubber buffer (18) fixedly.When pitman shaft (5) upwards forwards to above 0 °～15 ° of vertexs with dial (6) and crank (4), or forward to downwards when nadir also differs from 0 °～15 °, weight (15) is bearing in two weight bearings (17) respectively and goes up (Fig. 1, Fig. 2).Weight part (8) plays counterweight and position-limiting action, cooperates with dial (6) and discharging rocking bar (7), makes Dump gate (19) energy SELF CL.
During use, hopper (1) overhead has certain distance, opens Dump gate (19) and should not run into ground.Side at material outlet, the position that the bottom of the long rocking bar (14) of hopper in service (1) can be run into, need a bow type discharging arc plate (22) to be installed (Fig. 4), the arc that the top of discharging arc plate (22) curves for the strip shape steel plate, bottom level string limit is the straight steel plate of strip shape, discharging arc plate (22) is rack-mount, cooperates with discharging rocking bar (7) and carries out automatic discharging.When automatic discharge apparatus for rocker-counterweight type bottom-dump bucket is used for suspension bucket, in level run, swing, a secondary track (23) parallel with main orbit is installed, lean against on the lateral wall of suspension bucket (Fig. 4) in side of suspension bucket for preventing suspension bucket.When suspension bucket filled with the material operation, two pitman shafts (5) upwards forwarded to above 0 °～15 ° of vertexs, and Dump gate (19) is in closed condition.At this moment two baffle plates (10) of dial (6) and (11) and the relative plane of short rocking bar (13), extending to the bisector that intersects formed angle is in horizontal, two baffle plates (10) and (11) are positioned at the rear side (it is preceding filling with the material working direction with suspension bucket) of rotating shaft (3), baffle plate (10) is on top, and weight (15) and hammer stem (16) are bearing on the weight bearing (17) of suspension bucket back.Short rocking bar (13) is blocked by baffle plate (10), and the oblique upper to the suspension bucket back tilts, and long rocking bar (14) tiltedly tilts the below to the suspension bucket fwd, with horizontal surface 35 °～50 ° angle is arranged.When the feed bin oral area is arrived in the suspension bucket orbiting, the bottom of long rocking bar (14) touches the arc limit and the intersection, base of discharging arc plate (22) earlier, suspension bucket continues ahead running, and long rocking bar (14) is blocked by discharging arc plate (22), is shaken the back of suspension bucket by cw from the front of suspension bucket.When long rocking bar (14) was swung, short rocking bar (13) also swung to the front of suspension bucket simultaneously from the back cw of suspension bucket.Owing to stir the baffle plate (10) on the dial (6) during short rocking bar (13) swing, dial (6), rotating shaft (3), crank (4), weight (15) and hammer stem (16) all rotated to same direction with short rocking bar (13).Along with the rotation of dial (6) and crank (4), two pitman shafts (5) are rotated to low spot by height point, and connecting rod (21) then moves down, and Dump gate (19) is opened gradually, and material flows out from Dump gate (19).Suspension bucket continues ahead running, and long rocking bar (14) is lifted by the cambered surface of discharging arc plate (22), is raised to the top of cambered surface, and the angle of this duration rocking bar (14) swing is greater than 110 °.Other parts that short rocking bar (13) also drives in dial (6) and the rotating shaft (3) clockwise rotate to the suspension bucket front, when hammer stem (16) is transferred near with the horizontal surface upright position time, because the action of gravity of material, Dump gate (19) and connecting rod (21), make dial (6), rotating shaft (3), crank (4), weight (15) and hammer stem (16) no longer be subjected to the control of discharging rocking bar (7), continuation is rotated along former direction, falls to rotate when suspension bucket fwd weight bearing (17) is gone up when weight (15) and hammer stem (16) to stop.Dial (6), rotating shaft (3), crank (4), weight (15) and hammer stem (16) cw have forward changeed 180 °, two pitman shafts
