Description

Technical Field

[0001] The invention relates to the technical field of port machinery, in particular to a port belt conveyor. Background Art

[0002] Belt conveyor is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of a frame, conveyor belt, roller, drum, tensioning device, transmission device, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can convey both loose materials and pieced items. In addition to pure material conveying, it can also cooperate with the requirements of the process in the production process of various industrial enterprises to form a rhythmic flow operation transportation line. Belt conveyors can be divided into heavy-duty belt conveyors and light-duty belt conveyors according to their conveying capacity; heavy-duty belt conveyors are widely used in ports because of their high-speed, stable operation, low noise, and uphill transmission. When conveying materials with slightly higher viscosity, it is inevitable that they adhere to the belt and move with the belt. When the belt conveying surface turns to the bottom of the device, the adhered materials fall due to the vibration of the device or the influence of their own weight. It is not easy to clean due to the small operating space.

[0033] The transmission assembly drives the first connecting shaft 521 to rotate at a set angle in the first state, and stops the action with the help of the locking member 529 in the second state; the transmission assembly includes a switching motor 523, a rotating disk 524, a first gear 526, a first rack 525, a push-pull plate 527, a lever 528, and a second connecting shaft 522; the switching motor 523 drives the rotating disk 524 to rotate through a pair of meshing gear sets; the switching motor 523 is fixed on the support plate 53; the rotating disk 524 is a sector with a part of the circumference protruding outward; the first gear 526 is sleeved on the first connecting shaft The outer side of the shaft 521, that is, the first gear 526 is fixedly connected to the triangular mounting plate 41.

[0036] The swing assembly 51 includes a first cylinder 511 and a second cylinder 512; the first cylinder 511 and the second cylinder 512 are respectively located on both sides of the support frame 6, the piston rod ends of the first cylinder 511 and the second cylinder 512 are both hinged on the support plate 53, and the cylinder ends are both hinged on the support frame 6; the first cylinder 511 and the second cylinder 512 have opposite extension directions and can act simultaneously after the set time is reached; the distance sensor 54 is hinged on the support plate 53 through the gravity block, and under the action of the gravity block's own gravity, the distance sensor 54 always measures toward the bottom surface; after the swing assembly 51 works, the triangular mounting plate 41 becomes horizontal, and the distance sensor 54 detects the change in distance, thereby starting the switching motor 523; the action of the first cylinder 511 and the second cylinder 512 can be automatically started by pressing the start button or after the set time is reached; when the pressure sensing bar shows that the turntable 524 is in the second state, the swing assembly 51 is reset, so that the triangular mounting plate 41 becomes inclined again.

[0037] Embodiment 2

[0038] See also Figure 1-7 The difference between the second embodiment and the first embodiment is that on the basis of retaining the first embodiment, an oscillation component 7 is arranged in the discharge funnel 2; the oscillation component 7 includes an oscillation power shaft 71 and an oscillation plate 72; the oscillation power shaft 71 is hinged on the wall of the discharge funnel 2, and swings back and forth under the action of a stepper motor (not shown in the figure); the oscillation plate 72 is located in the discharge funnel 2 and one end is connected to the oscillation power shaft 71; the axis of the oscillation power shaft 71 is parallel to the power roller of the conveyor belt body 1; the end of the oscillation plate 72 away from the oscillation power shaft 71 is hinged with a telescopic shaft 73; the two ends of the telescopic shaft 73 are respectively hinged to the inner wall of the discharge funnel 2 and the back of the oscillation plate 72.

[0039] Embodiment 3

[0040] See also Figure 1-7 The difference between Example 3 and Example 2 is that on the basis of retaining Example 2, a sealing cover body 8 is installed on the outer side of the conveyor belt body 1; the sealing cover body 8 is communicated with the discharge funnel 2; the top of the discharge funnel 2 is also a sealing structure; the material receiving channel 3 is also a cylindrical structure with only two ends open; the setting of the sealing cover can avoid dust, thereby avoiding environmental pollution.

[0041] The working process of the present invention is as follows: the power drive of the transmission belt body is started, the material is sent to the discharge funnel 2, the oscillation power shaft 71 of the discharge funnel 2 swings back and forth, so that the oscillation plate 72 reciprocates toward the conveyor belt body 1, and the material is prevented from being blocked at the end of the conveyor belt body 1; the conveyor belt body 1 is continuously conveyed forward, one of the scraper knives 42 rubs against the conveyor belt body 1, and the residual material falls to the surface of the triangular mounting plate 41, and falls to the material receiving channel 3 under the guidance of the other two scraper knives 42, and is sent to the discharge funnel 2 under the action of gravity;

[0042] When the scraper blade 42 is severely worn after being used for a period of time, after manual start or the set time is reached, the control system controls the first cylinder 511 and the second cylinder 512 to operate. At this time, the support plate 53 and the triangular mounting plate 41 are in a horizontal state, and the distance sensor 54 detects the change in distance and transmits the signal to the control system. Under the action of this signal, the control system starts the switching motor 523; the switching motor 523 drives the rotating disk to rotate, and when the rotating disk is in the first state, the lever 528 drives the push-pull plate 527 to move to the side where the locking member 529 is located, so that the locking member 529 is disengaged from the first gear 526, and at the same time, the first rack 525 meshes with the first gear 526 and drives the first gear 526 and the triangular mounting plate 41 to rotate 120°, completing the rotation and replacement of the scraper 42; when the turntable 524 continues to rotate and is in the second state, the locking member 529 returns to the space between the teeth of the first gear 526, inhibiting the rotation of the first gear 526, and at the same time, the pressure sensing strip detects that the turntable 524 is in the second state, thereby stopping the switching motor 523 and returning the swing assembly 51 to its original position; after the switching is completed, the operator can replace the severely worn scraper 42 from the triangular mounting plate 41.
