[0025] Example 1

[0026] like Figures 1-4 As shown:

[0027] The discharging belt conveyor equipment anti-blocking device comprises an induction mechanism and a shoveling mechanism. The induction mechanism is installed on the top of the rack 11 of the belt conveyor 1 close to the discharging direction, and is electrically connected with the conveying motor 12 of the belt conveyor 1. The shoveling mechanism is installed on the rack 11 of the belt conveyor 1 close to the feeding direction, and the shoveling shovel 5 of the shoveling mechanism extends to the position above the belt conveyor 1 close to the middle of the belt conveyor 1 and shovels the blocked material to the feeding direction.

[0028] The induction mechanism comprises support rods 21 symmetrically installed on the rack 11 of the belt conveyor 1. Rotating rods 23 are arranged on the two support rods 21 in a rotating mode. The bottom of the rotating rod 23 is provided with a vertical baffle 24 close to the position of the belt conveyor 1. The one end of the rotating rod 23 is provided with an induction block 25.

[0029] The top end of the support rod 21 is provided with a support groove 22. The rotating rod 23 is arranged on the support groove 22 and is connected with the support groove 22 in a rotating mode.

[0030] The induction mechanism further comprises a proximity switch 26 arranged in a horizontal mode. The proximity switch 26 is installed on the rack 11 of the belt conveyor 1 through a mounting frame 27. The proximity switch 26 is arranged close to the induction block 25 and is matched with the lower end of the induction block 25 to act.

[0031] The proximity switch 26 is electrically connected with the conveying motor 12.

[0032] In use, in the normal state, the material of the discharging trolley falls on the belt conveyor 1. The material pushes the baffle 24 in the normal conveying process. The baffle 24 drives the rotating rod 23 to rotate, and the induction block 25 rotates accordingly. When the material at the discharging opening of the discharging trolley is blocked, no material passes through the induction mechanism, the baffle 24 is not pushed by the material, and the baffle 24 returns to the vertical state, so that the rotating rod 23 rotates to drive the induction block 25 to return to the vertical state. At this time, the proximity switch 26 senses the lower end of the induction block 25, and the proximity switch 26 controls the conveying motor 12 to stop, so that the belt conveyor 1 stops running, thereby avoiding the long-time contact and friction between the belt conveyor 1 and the blocked material at the discharging opening, and preventing the large-area damage of the belt conveyor 1.

[0033] A scraping rod 3 is arranged between the induction mechanism and the shoveling mechanism and is arranged on the belt conveyor in a cross mode.

[0034] The number of the shoveling mechanism is two. The two shoveling mechanisms are symmetrically arranged on the rack 11 of the belt conveyor 1.

[0035] The poking mechanism comprises a housing 41, three windows 42 corresponding to the poking shovel 5 are arranged on the side wall of the housing 41, a crank 43 is arranged in the housing 41 and connected with the poking shovel 5, and the driving motor 6 is connected with the lower crank arm.

[0036] The crank 43 comprises two crank arms arranged oppositely and a crank pin connected between the two crank arms, one end of the poking shovel 5 in the housing 41 is connected with the crank pin through a rotating sleeve 44, the upper crank arm is connected with the housing 41, and the lower crank arm is connected with the driving motor 6.

[0037] The lower crank arm is provided with a driven gear 45 arranged coaxially, the output end of the driving motor 6 is provided with a driving gear 61, and the driving gear 61 is connected with the driven gear 45 through a transmission belt 62.

[0038] The poking shovel 5 comprises a connecting rod 51 and a shovel head 52, the outer end of the connecting rod 51 is connected with the shovel head 52, the inner end of the connecting rod 51 is connected with the rotating sleeve 44, and the shovel head 52 is used for poking the blocked material to move to the incoming material direction.

[0039] As shown in Figure 4 the figure, the crank pin is in the initial state at point A, when the driving motor 6 starts to drive the driving gear 61 to rotate, the driving gear 61 drives the driven gear 45 to rotate through the transmission belt 62, and then the driven gear 45 drives the crank pin of the crank 43 to rotate counterclockwise.

[0040] When the crank pin of the crank 43 rotates from point A to point B, the poking shovel 5 extends outward, and the shovel head 52 starts to insert into the blocked material.

[0041] When the crank pin of the crank 43 rotates from point B to point C, the poking shovel 5 continues to extend outward, the shovel head 52 continues to insert into the blocked material, and the poking shovel 5 pokes the material to move to the incoming material direction to dredge the blocked material.

[0042] When the crank pin of the crank 43 rotates from point C to point D, the shovel head 52 pokes the material and then retracts to the outgoing material direction, so as to avoid taking the material away from the belt conveyor 1.

[0043] When the crank pin of the crank 43 rotates from point D to point A, the poking shovel 5 retracts inward, and after the poking shovel 5 retracts, the poking shovel 5 is located above the rack 11 outside the housing, and in the normal working state of the belt conveyor 1, the poking shovel 5 will not block the normal conveying of the material.

[0044] Through the multiple poking of the poking shovel 5 driven by the crank 43, the blocked material is pushed flat or to the incoming material position, the blocked material is dredged, manual pushing is avoided, and the automation degree is improved.

[0045] The utility model discloses a setting with the induction mechanism of the conveying motor electric connection of adhesive tape conveyer, makes the adhesive tape conveyer shutdown when sensing no material conveying, avoids the situation that the adhesive tape conveyer is caused large area damage to happen by the long time contact friction of adhesive tape conveyer and blanking material material blockage, through setting the material stirring mechanism and stirring the blocked material backward and unblocking the blocked material, avoid long time material accumulation, reduce the serious influence of blanking material accumulation to production, safety.
