Description

Technical Field

[0001] The utility model relates to the technical field of charging bins, in particular to a charging bin for a stone crusher. Background Art

[0002] In the field of ore mining, it is usually necessary to crush large pieces of ore into uniform small volumes for easy transportation and later smelting. Before being crushed, the ore is transported to the feeding bin of the crusher by a conveyor belt. Due to the heavy weight of the ore itself, when it falls into the feeding bin, it keeps hitting the bottom of the feeding bin, which will cause the bottom of the feeding bin to be worn and penetrated, affecting the normal operation of the crusher. At the same time, when the bottom of the feeding bin is damaged, if the entire feeding bin is replaced, the maintenance cost is too high. Therefore, the existing practice is to add a layer of wear-resistant plate at the bottom of the feeding bin and lock it with a large number of screws, which is not convenient for disassembly and assembly.

[0003] A Chinese patent with publication number CN208990971U discloses a feeding bin for a crusher, which is used to receive ore from a conveyor belt and transfer it to a crusher. The feeding bin for the crusher includes a bin body and a pad laid on the bottom of the bin body. The bin body includes a square bottom wall and two side walls and a rear wall perpendicular to the bottom wall and arranged around the bottom wall. The bottom wall, the side walls and the rear wall enclose a receiving space. The side walls are respectively provided with long positioning ribs protruding toward the receiving space. The positioning ribs are arranged parallel to each other and form an angle with the bottom wall.

[0026] Embodiment 1

[0027] like Figure 1-Figure 3 As shown, the utility model provides a charging bin for a stone crusher, comprising a base 1, a foot 2, a shock-absorbing bracket 3, a shock-absorbing spring 4, a connecting frame 5, a collecting bucket 6, a sliding plate 7, a telescopic rod 8, a transmission member 9, a rotating shaft 10, a rotating connecting rod 11, a sliding member 12, a spring 13, a connecting bracket 14, a feeding belt 15, a side baffle 16, a blocking member 17, a rotating bracket 18, a discharging chute 19, a rotating telescopic rod 20 and an impact member 21;

[0028] A plurality of sets of feet 2 are provided at the bottom of the base 1; a shock-absorbing bracket 3 is provided on the top of the base 1; a collecting structure for feed buffering is provided on the shock-absorbing bracket 3; a conveying structure for shock-absorbing transportation adjustment is provided on the side of the inner wall of the base 1; a rotating bracket 18 is provided on the base 1; a discharging structure for reducing discharging residue is provided on the rotating bracket 18.

[0029] The collecting structure includes a shock absorbing spring 4; a connecting frame 5 is provided on the top of one end of the shock absorbing spring 4 away from the shock absorbing bracket 3; a collecting bucket 6 is provided on the side of the inner wall of the connecting frame 5; a sliding plate 7 for sliding connection is provided on the bottom of the collecting bucket 6; a transmission member 9 is provided on the side of the sliding plate 7; a connecting bracket is provided on the bottom of the collecting bucket 6, and a telescopic rod 8 is provided on the connecting bracket; the output end of the telescopic rod 8 is connected to the transmission member 9;

[0030] The conveying structure includes a rotating shaft 10; a rotating connecting rod 11 is provided on the side of the rotating shaft 10; a rotating connected sliding member 12 is provided on the end of the rotating connecting rod 11 away from the rotating shaft 10; a spring 13 is provided on the side of the sliding member 12; the spring 13 is arranged between multiple groups of sliding members 12; a slidably connected connecting bracket 14 is provided on the side of the sliding member 12; a feeding belt 15 is provided on the side of the connecting bracket 14; a side baffle 16 is provided on the top of the connecting bracket 14; a blocking member 17 is provided on the side of the side baffle 16 away from the discharge end of the feeding belt 15; the blocking member 17 is in contact with the top of the feeding belt 15;

[0031] The discharging structure includes a discharging trough 19; the side of the discharging trough 19 is rotatably connected to the rotating bracket 18; a striking member 21 is provided on the side of the base 1; a rotatably connected rotating telescopic rod 20 is provided on the base 1; the output end of the rotating telescopic rod 20 is rotatably connected to the bottom of the discharging trough 19.

[0032] In this embodiment, the device can effectively improve the feeding and conveying stability of crushed stone raw materials. Compared with the traditional structure, the device adopts a variety of buffer and shock-absorbing structures to effectively reduce the damage of the device caused by the impact of crushed stones. At the same time, the device can control the discharge speed of the device through the structure of the feeding belt 15, avoiding problems such as excessive accumulation or uneven falling of raw materials.

[0033] By connecting the frame 5 and the multiple groups of shock-absorbing springs 3, when the crushed stones fall into the collecting bucket 6, the structure of the shock-absorbing springs 3 can improve the buffering effect of the impact of the crushed stones, thereby avoiding the rigid collision between the crushed stones and the collecting bucket 6 or the sliding plate 7, which may cause damage to the structure of the device.

[0034] By driving the transmission member 9 to slide through the telescopic rod 8, and driving the sliding plate 7 to slide through the transmission member 9, the size of the opening at the bottom of the collecting bucket 6 can be controlled and adjusted. When the crushed stones are stuck or blocked, the sliding plate 7 can be used to increase the material discharge area and alleviate the blocking condition.

[0035] The sliding key 12 is limited by the connecting bracket 14, and the multiple groups of sliding members 12 are reset after sliding by the spring 13. The feeding belt 15 can achieve the effect of shock absorption support by driving the rotating connecting rod 11 to rotate by the rotating shaft 10. When the gravel falls onto the feeding belt 15, the weight on the top of the feeding belt 15 increases, and the distance between the multiple groups of sliding members 12 is reduced by pressing downward. At this time, the spring 13 is in a compressed state, and the elasticity of the spring 13 can only be increased, so that after the feeding belt 15 drops to a certain extent, the elastic force of the spring 13 reaches a balanced state with the sliding member 12 again. At this time, the feeding belt 15 is in a stable state at the new height position. When the crushed stone falls from the feeding belt 15 to the inside of the discharge chute 19, the weight on the feeding belt 15 decreases. At this time, the spring 13 releases the elastic potential energy to restore the feeding belt 15 to its original height, thereby achieving the effect of automatic reset. The feeding belt 15 changes height with the weight, thereby achieving the buffering effect of the device and reducing the impact and friction of the crushed stone on the surface of the feeding belt 15. The elastic support effect can prevent the crushed stone from rigidly colliding after falling on the surface of the feeding belt 15, thereby extending the service life of the feeding belt 15. The side baffle 16 and the blocking member 17 can prevent the crushed stone from accidentally slipping when entering the feeding belt 15 from the collecting bucket 6.

[0036] The discharging trough 19 is driven to rotate by rotating the telescopic rod 20, and the discharging trough 19 comes into contact with the impact member 21, thereby generating a vibration and impact effect inside the discharging trough 19, thereby avoiding problems such as residual gravel inside the discharging trough 19. At the same time, the rotation and tilting within a certain angle range can reduce the difficulty of docking the downstream equipment with the device, thereby improving the combination compatibility of the device.

Compared with the first embodiment, in this embodiment, a mounting groove is provided inside the connecting frame 5, and a mounting joint is provided on the side of the collecting bucket 6, and the mounting joint is connected to the mounting groove.
