[0002] The coal plow is a kind of unloading device widely used on belt conveyors. It uses electric push rods or electro-hydraulic push rods as the power source. There are three types of unloading: double-sided, right-sided, and left-sided. It is a key link in achieving accurate material distribution. At present, in order to improve the economic efficiency of power generation, the requirements for accurate coal blending of digital coal yards and units are getting higher and higher.

[0011] Furthermore, a linkage mechanism is provided on the inner side of the coal unloading frame, the linkage mechanism comprises a connecting rod fixedly connected to the top of the coal unloading frame, one end of the connecting rod away from the coal unloading frame is fixedly connected to a sliding rod, and one end of the sliding rod away from the connecting rod is slidably connected to a sliding sleeve.

[0012] Furthermore, the linkage mechanism also includes a rotating shaft rotatably connected to the end of the sliding sleeve away from the connecting rod, a plurality of extrusion rotating columns are fixedly connected to the middle of the rotating shaft, and a pressure spring is sleeved on the end of the sliding rod close to the connecting rod.

[0014] A method for using a lifting double-plowshare coal plow comprises the following steps:

[0015] Step 1: Lower the coal unloading rack to unload coal;

[0016] Step 2: Lay down the conveyor belt to assist in unloading coal;

[0017] Step 3: Prevent unloaded coal from piling up.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention provides an anti-stacking mechanism. When the extrusion rotating column rotates and drives the sliding sleeve to rotate, the sliding sleeve drives the transmission belt to rotate, and the transmission belt drives the worms at both ends of the rotating column to rotate. At this time, when the sliding sleeve moves upward along the sliding rod, the worm is meshed with the worm wheel. The rotation of the worm drives the conveying shaft at the bottom of the worm wheel to rotate. The rotation of the conveying shaft drives the anti-blocking conveyor belt to rotate. The rotation of the anti-blocking conveyor belt drives the coal accumulated on the surface of the coal unloading rack to move to both sides of the coal conveying conveyor belt. This arrangement is conducive to the anti-blocking conveyor belt to assist the coal unloading rack to unload coal quickly, avoiding a large amount of coal from accumulating on the surface of the coal unloading rack in a short period of time, thereby improving the coal unloading rate of the device.

[0020] (2) According to the present invention, when the lifting double-plowshare coal plow is used, the hydraulic cylinder is first started, and the hydraulic cylinder drives the push rod to retract, and the push rod drives the lifting frame at one end to rotate along the fulcrum of the lifting frame and the supporting frame. At this time, the lifting frame drives the coal unloading frame and the plow-shaped block to approach the coal conveying conveyor belt, and at the same time, the driving groove at the bottom of the lifting frame drives the auxiliary frame on the driving column to move backward along the sliding rod. The auxiliary frame moves backward to drive the extrusion column inside the special-shaped extrusion groove to be extruded with the special-shaped extrusion groove. At this time, the extrusion column drives several sliding columns on the sliding base to move upward, and the sliding column moves upward to drive the coal conveying conveyor belt on the sliding column to approach the coal unloading frame and the plow-shaped block. When the coal unloading frame contacts the coal conveying conveyor belt, the push rod stops moving. At this time, the coal on the coal conveying conveyor belt is evenly moved to both sides of the plow-shaped block through the plow-shaped block. At this time, under the guiding action of the coal unloading frame, the coal on the coal conveying conveyor belt enters the coal storage box on both sides along the coal unloading frame. This is conducive to the stable unloading of the coal on the coal conveying conveyor belt into the coal storage box on both sides of the device.

[0021] (3) The present invention provides a leveling mechanism. When the lifting frame rotates along the fulcrum between the lifting frame and the supporting frame, the driving groove at the bottom of the lifting frame drives the auxiliary frame on the driving column to move backward along the sliding rod. The auxiliary frame moves backward to drive the sliding base on the extrusion column to move upward. The sliding base moves upward to drive the leveling rotating column on the fixed plate to move upward. At this time, under the pulling action of the fixed column, the inclination angle of the inclined rotating column gradually decreases until the axis of the inclined rotating column and the leveling rotating column are on the same horizontal line. Such a setting is conducive to the coal conveyor belt on the top of the inclined rotating column to be transformed from a V-shaped setting to a horizontal setting, which is conducive to the smooth unloading of coal on the coal conveyor belt.

[0022] (4) The present invention sets a linkage mechanism. When the lifting frame drives the coal unloading frame to descend toward the side close to the coal conveyor belt, the extrusion rotating column at the bottom of the sliding sleeve is squeezed with the surface of the coal conveyor belt. The extrusion rotating column rotates under the friction force of the coal conveyor belt. At this time, the extrusion rotating column drives the sliding sleeve at one end of the rotating shaft to squeeze the pressure spring upward along the sliding rod. The pressure spring is squeezed and the length is shortened. At this time, the elastic force of the pressure spring increases, and the force of the pressure spring on the sliding sleeve increases. Then, the extrusion force of the sliding sleeve on the extrusion rotating column and the coal conveyor belt increases, and the friction force of the coal conveyor belt on the extrusion rotating column increases. Therefore, the torque generated by the extrusion rotating column increases. Such a setting is beneficial for the extrusion rotating column to fully squeeze the coal conveyor belt so that the coal on the coal conveyor belt will not leak out along the gap between the coal unloading frame and the coal conveyor belt. On the other hand, increasing the rotation torque of the extrusion rotating column is beneficial to the normal operation of the subsequent mechanism.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The interior of the lifting frame 201 is provided with an anti-stacking mechanism 5, which includes a transmission belt 501 that is transmission-connected to the middle of the rotating shaft 404, a rotating column 502 that is rotationally connected to the end of the sliding sleeve 403 away from the rotating shaft 404, and a worm 503 that is fixedly connected to both ends of the rotating column 502, a plurality of conveying shafts 504 that are rotationally connected to the interior of the coal unloading frame 210, a worm gear 505 that is fixedly connected to the top of the conveying shaft 504, and an anti-blocking conveying belt 506 that is rotationally connected to the end of the conveying shaft 504 that is away from the worm gear 505, and a limiting column 507 that is rotationally connected to one side of the coal unloading frame 210, and the limiting column 507 that is extruded with the anti-blocking conveying belt 506, and the function of this component is that when the extruding rotating column 405 rotates, the sliding sleeve 403 is driven to rotate When rotating, the sliding sleeve 403 drives the transmission belt 501 to rotate, and the transmission belt 501 drives the worm 503 at both ends of the rotating column 502 to rotate. At this time, when the sliding sleeve 403 moves upward along the sliding rod 402, the worm 503 engages with the worm wheel 505, and the rotation of the worm 503 drives the conveying shaft 504 at the bottom of the worm wheel 505 to rotate. The rotation of the conveying shaft 504 drives the anti-blocking conveyor belt 506 to rotate. The rotation of the anti-blocking conveyor belt 506 drives the coal accumulated on the surface of the coal unloading rack 210 to move to both sides of the coal conveying conveyor belt 11. This arrangement is conducive to the anti-blocking conveyor belt 506 to assist the coal unloading rack 210 to unload coal quickly, avoid a large amount of coal from accumulating on the surface of the coal unloading rack 210 in a short time, thereby improving the coal unloading rate of the device.

[0046] A method for using a lifting double-plowshare coal plow comprises the following steps:

[0047] Step 1: Lower the coal unloading rack to unload coal;

[0048] Step 2: Lay down the conveyor belt to assist in unloading coal;

[0049] Step 3: Prevent unloaded coal from piling up.

[0050] A specific application of this embodiment is:

[0051] When the lifting double plowshare coal plow is used, the hydraulic cylinder 14 is first started, and the hydraulic cylinder 14 drives the push rod 16 to retract, and the push rod 16 drives the lifting frame 201 at one end to rotate along the fulcrum between the lifting frame 201 and the support frame 12. At this time, the lifting frame 201 drives the coal unloading frame 210 and the plow-shaped block 211 to approach the coal conveyor belt 11, and at the same time, the driving groove 206 at the bottom of the lifting frame 201 drives the auxiliary frame 205 on the driving column 207 to move backward along the sliding rod 203, and the auxiliary frame 205 moves backward to drive the special-shaped The extrusion column 304 inside the extrusion groove 303 is squeezed with the special-shaped extrusion groove 303. At this time, the extrusion column 304 drives the plurality of sliding columns 302 on the sliding base 301 to move upward. The sliding columns 302 move upward to drive the coal conveyor belt 11 on the sliding columns 302 to approach the coal unloading frame 210 and the plow-shaped block 211. When the coal unloading frame 210 contacts the coal conveyor belt 11, the push rod 16 stops moving. At this time, the coal on the coal conveyor belt 11 passes through the plow-shaped block 211 and is evenly moved to both sides of the plow-shaped block 211. At the same time, under the guidance of the coal unloading frame 210, the coal on the coal conveyor belt 11 enters the coal storage boxes on both sides along the coal unloading frame 210, which is conducive to the stable unloading of the coal on the coal conveyor belt 11 into the coal storage boxes on both sides of the device; by setting the leveling mechanism 3, when the lifting frame 201 rotates along the fulcrum of the lifting frame 201 and the supporting frame 12, the driving groove 206 at the bottom of the lifting frame 201 drives the auxiliary frame 205 on the driving column 207 to move backward along the sliding rod 203, and the auxiliary frame 205 moves backward The sliding base 301 on the squeezing column 304 is driven to move upward, and the upward movement of the sliding base 301 drives the leveling rotating column 306 on the fixed plate 305 to move upward. At this time, under the pulling action of the fixed column 309, the inclination angle of the inclined rotating column 307 is gradually reduced until the axis of the inclined rotating column 307 and the leveling rotating column 306 are on the same horizontal line. This setting is conducive to the coal conveying conveyor belt 11 on the top of the inclined rotating column 307 to change from a V-shaped setting to a horizontal setting, which is conducive to the smooth unloading of coal on the coal conveying conveyor belt 11;

[0052] By setting the linkage mechanism 4, when the lifting frame 201 drives the coal unloading frame 210 to descend to the side close to the coal conveyor belt 11, the extrusion rotating column 405 at the bottom of the sliding sleeve 403 is squeezed with the surface of the coal conveyor belt 11, and the extrusion rotating column 405 rotates under the friction force of the coal conveyor belt 11. At this time, the extrusion rotating column 405 drives the sliding sleeve 403 at one end of the rotating shaft 404 to squeeze the pressure spring 406 upward along the sliding rod 402. The pressure spring 406 is squeezed and the length is shortened. At this time, the elastic force of the pressure spring 406 increases, and the force of the pressure spring 406 on the sliding sleeve 403 increases. Then, the extrusion force of the sliding sleeve 403 on the extrusion rotating column 405 and the coal conveyor belt 11 increases, and the friction force of the coal conveyor belt 11 on the extrusion rotating column 405 increases. Therefore, the torque generated by the extrusion rotating column 405 to rotate increases. This arrangement is conducive to the extrusion rotating column 405 to fully squeeze the coal conveyor belt 11 so that the coal on the coal conveyor belt 11 will not The coal is then sucked out of the coal unloading rack 210 and the coal conveying belt 11. On the other hand, increasing the rotational torque of the extruding rotating column 405 is beneficial to the normal operation of the subsequent mechanism. By setting the anti-pile mechanism 5, when the extruding rotating column 405 rotates and drives the sliding sleeve 403 to rotate, the sliding sleeve 403 drives the transmission belt 501 to rotate, and the transmission belt 501 drives the worm 503 at both ends of the rotating column 502 to rotate. At this time, when the sliding sleeve 403 moves upward along the sliding rod 402, the worm 503 is meshed with the worm wheel 505, and the rotation of the worm 503 drives the conveying shaft 504 at the bottom of the worm wheel 505 to rotate. The rotation of the conveying shaft 504 drives the anti-blocking conveyor belt 506 to rotate. The anti-blocking conveyor belt 506 rotates and drives the coal accumulated on the surface of the coal unloading rack 210 to move to both sides of the coal conveying conveyor belt 11. This arrangement is beneficial to the anti-blocking conveyor belt 506 to assist the coal unloading rack 210 in quickly unloading coal, avoiding a large amount of coal from accumulating on the surface of the coal unloading rack 210 in a short time, thereby improving the coal unloading rate of the device.
