Description

Technical Field

[0001] The invention relates to the technical field of belt coal conveyor unloading, in particular to a plough type unloader of a belt coal conveyor. Background Art

[0002] The plow type unloader is a kind of unloading device of the belt coal conveyor. It is mainly used to unload the materials (such as coal, ore and other bulk materials) on the conveyor belt as needed during the operation of the conveyor belt. It is installed above the conveyor belt and cuts into the material layer of the conveyor belt through the plow plate to change the direction of movement of the material, thereby realizing unloading.

[0003] When the plow type discharger is used on the belt coal conveyor, when the weight of the materials on the conveyor belt is uneven, the tension of the conveyor belt will change. When the material is heavy, the conveyor belt sinks more, and when the material is light, the sinking degree is small. This change will cause the gap between the plow type discharger and the conveyor belt to be unstable, affecting the unloading effect. If the gap is too large, the material may not be completely unloaded. If the gap is too small, the wear of the conveyor belt and the plow type discharger will increase. For this reason, we propose a plow type discharger for the belt coal conveyor. Summary of the invention

[0041] It should be noted here that the moldboard 103 is rotatably connected by the mounting frame 701 , the rotating shaft 702 and the connecting block 703 .

[0042] Preferably, the adjustment component includes a worm wheel 801 fixed to one end of the rotating shaft 702, a fixing frame 802 is fixed on the mounting frame 701, a rotating shaft 803 is rotatably connected to the fixing frame 802, a worm 804 is fixed to one end of the rotating shaft 803, the worm 804 and the worm wheel 801 are meshed with each other, and a driving component for driving the rotating shaft 803 is arranged between the support frame 601 and the rotating shaft 803;

[0043] It should be noted here that: when the materials piled on the conveyor belt 102 are heavy and cause the strip frame 4 to be forced to move downward, as the strip frame 4 descends, the mutual meshing transmission between the rack 902 and the gear 901 drives the rotating shaft 803 and the worm 804 at one end of the rotating shaft 803 to rotate. During the rotation of the worm 804, the mutual meshing transmission between the worm 804 and the worm wheel 801 drives the rotating shaft 702 to rotate.

[0046] Preferably, the telescopic assembly includes a threaded rod 1101 rotatably connected to the back of the plowboard 103, a threaded tube 1102 is threadedly engaged with the threaded rod 1101, one end of the threaded tube 1102 is fixed to the L-shaped baffle 10, a driving motor 1103 for driving the threaded rod 1101 is installed on the back of the plowboard 103, two groups of third sliding rods 1104 are fixed to the back of the plowboard 103, the two groups of third sliding rods 1104 are symmetrically arranged on both sides of the threaded rod 1101, a third sleeve 1105 is slidably connected to the third sliding rod 1104, and one end of the third sleeve 1105 is fixed to the L-shaped baffle 10;

[0047] It should be noted here that: the threaded rod 1101 is driven to rotate by driving the motor 1103. During the rotation of the threaded rod 1101, the mutual meshing transmission between the threaded rod 1101 and the threaded tube 1102 and the sliding guiding effect of the third sleeve 1105 and the third slide rod 1104 are used to make the L-shaped baffle 10, which is subjected to force, move telescopically toward or away from the plowboard 103.

[0048] Preferably, two groups of support components are symmetrically arranged, and the support components include a connecting frame 1201 fixed to the lower end of the conveyor frame 101, a connecting shaft 1202 is rotatably connected to the connecting frame 1201, and a supporting roller 1203 for supporting against the inner side of the conveyor belt 102 is fixed to the connecting shaft 1202;

[0049] It should be noted here that: through the counter-supporting effect of the support roller 1203 of the connecting shaft 1202 on the connecting frame 1201 and the conveyor belt 102, the conveyor belt 102 can be kept taut, which further facilitates the stable transportation of materials.

[0050] In this scheme: a plow type unloader of a belt type coal conveyor comprises the following steps:

[0051] During the use of the belt coal conveyor, the material is placed on the conveyor belt 102, and the conveyor belt 102 is driven by the driving component to transport the placed material on the conveyor belt 102. During the transportation process, the material transported on the conveyor belt 102 is against the plowboard 103, and the oblique guiding effect of the plowboard 103 causes the material to be transported toward the side of the plowboard 103 connected with the L-shaped baffle 10. During the transportation process, the material is against the L-shaped baffle 10 and falls under the L-shaped baffle 10, and the material transported on the conveyor belt 102 is unloaded. During the transportation and unloading process, the drive roller 205 is pushed by the elastic component to keep against the inner side of the conveyor belt 102. When the weight of the material placed on the conveyor belt 102 changes, the material and the conveyor belt 102 are pressed against each other. The driving roller 205 is used to promote the synchronous lifting and lowering movement with the change of the weight of the material on the conveyor belt 102. During the movement of the driving roller 205, the strip frame 4 is driven to move synchronously through the connection and transmission action of the U-shaped frame 203, the fixed plate 501, the strip plate 502 and the connecting rod 503. During the movement of the strip frame 4, the plowboard 103 is driven to move synchronously up and down through the connection action of the rotating assembly. Therefore, when the conveyor belt 102 sinks to different degrees due to the change of the weight of the placed material, the plowboard 103 is driven to move synchronously up and down through the transmission, and the relative gap between the plowboard 103 and the upper end of the conveyor belt 102 is maintained. Through the control of the gap, it can not only ensure the effective unloading of the material on the conveyor belt 102, but also avoid the wear of the conveyor belt 102 caused by too small a gap, which is convenient for the unloading operation on the belt type coal conveyor;

[0052] When the materials piled on the conveyor belt 102 are heavy and cause the strip frame 4 to be forced to move downward, as the strip frame 4 descends, the rack 902 and the gear 901 are meshed with each other to drive the rotating shaft 803 and the worm 804 at one end of the rotating shaft 803 to rotate. During the rotation of the worm 804, the worm 804 and the worm wheel 801 are meshed with each other to drive the rotating shaft 702 to rotate. During the rotation of the rotating shaft 702, the plowboard 103 is driven to steer through the connecting block 703. By adjusting the steering of the plowboard 103, the plowboard 103 is The plate 103 is used at a smaller inclination angle. The smaller angle can make the moldboard 103 contact the material relatively smoothly, and reduce the pressure on the conveyor belt 102 and the resistance of the material while ensuring effective unloading. On the contrary, when the material piled on the conveyor belt 102 is light and causes the bar frame 4 to be forced to rise, the moldboard 103 is used at a larger inclination angle through transmission. By appropriately increasing the use angle of the moldboard 103, the moldboard 103 can better cut into the material, ensure the integrity of the unloading, avoid the material remaining on the conveyor belt 102, and ensure the unloading effect.

[0053] During the process of adjusting the angle of the moldboard 103, the distance between the L-shaped baffle 10 and one end of the moldboard 103 is adjusted by the telescopic assembly (see FIG. Figure 8 and Fig. 9 ), by adjusting the spacing, the plowboard 103 can control the falling position of the material after the L-shaped baffle 10 blocks the material while rotating, which further facilitates more accurate unloading and collection operations.
