Description

Technical Field

[0001] The utility model relates to the technical field of early warning devices, and more specifically, to an early warning device for detecting iron blocks in aggregate transportation based on a conveyor belt. Background Art

[0002] The aggregate raw materials are the iron surrounding rock that has been coarsely crushed after magnetic separation. The coarsely crushed iron surrounding rock is transported to the intermediate storage warehouse by belt conveyor for temporary storage, and then quantitatively measured before leaving the warehouse and then transported to the medium crushing workshop by belt conveyor. The medium crushing is carried out by using two cone crushers in series in the secondary crushing system.

[0003] In the processing of aggregate raw materials, iron blocks will be mixed in the aggregates, so it is necessary to detect and warn of the iron blocks to prevent the iron blocks from causing damage to the cone crusher during the crushing of the aggregate raw materials, which will cause the production line to stagnate and limit the efficiency of the upstream and downstream. In actual use, the existing detection and warning devices mostly adopt a fixed design, so that the warning device can only sound an alarm in a fixed direction, limiting the warning range of the warning device, making it difficult for operators in other directions to hear the alarm sound, so there is a need for improvement.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 5 As shown, the utility model provides an iron block detection and early warning device in aggregate transportation based on a conveyor belt, comprising:

[0029] A bracket 1, a vertical rod 2 is fixedly installed in the middle of the front end of the bracket 1, and a horizontal rod 3 is movably installed on the top of the rear end of the vertical rod 2;

[0030] A rotating mechanism 4, wherein the rotating mechanism 4 is arranged above the cross bar 3;

[0031] A driving mechanism 5, which is arranged at the top of the crossbar 3;

[0032] Among them, the rotating mechanism 4 includes a fixed box 401, which is fixedly installed on the top of the cross bar 3, and a round rod 402 is movably sleeved on the left side of the top of the fixed box 401. The bottom end of the round rod 402 penetrates the fixed box 401 and extends to the inside of the fixed box 401 and is fixedly sleeved with a driven gear 403. The top of the driven gear 403 is movably connected to the top of the fixed box 401. A control box 404 is fixedly installed on the top of the round rod 402, and the bottom end of the control box 404 is movably connected to the top of the fixed box 401.

The driven gear 403 will cause the control box 404 to rotate.

[0033] When the driven gear 403 rotates, since the inner surface of the driven gear 403 and the outer surface of the round rod 402 are fixedly connected, the round rod 402 will rotate together with the driven gear 403, so that the control box 404 fixedly connected to the round rod 402 will rotate along with the alarm light 405 and the alarm horn 406, thereby adjusting the alarm range of the early warning device, so that the alarm horn 406 can sound an alarm within a range of 360 degrees, thereby increasing the alarm range of the early warning device and allowing operators in different positions to hear the alarm in time.

[0034] Wherein, the driving mechanism 5 comprises:

[0035] The driving motor 501 is fixedly mounted on the right side of the top of the cross bar 3 and is located inside the fixed box 401.

[0037] When the driving motor 501 is started, the driving shaft 502 drives the driving gear 503 to rotate, thereby causing the driven gear 403 meshing with the driving gear 503 to rotate.

[0038] Among them, an iron block detector 6 is fixedly installed on the bottom end of the cross bar 3, and a slider 7 is fixedly installed on the right end of the cross bar 3. The outer surface of the slider 7 and the inner surface of the vertical bar 2 are movably connected.

[0039] When the slider 7 moves, the cross bar 3 and the iron block detector 6 will be driven to move along the outer surface of the vertical bar 2 .

[0040] Among them, the left and right ends of the vertical rod 2 are respectively provided with limiting grooves 8, and the top of the limiting groove 8 is movably sleeved with limiting blocks 9. There are two limiting blocks 9, and the opposite surfaces of the two limiting blocks 9 are respectively fixedly connected to the left and right ends of the slider 7.

[0041] The inner surface of the limiting groove 8 and the outer surface of the limiting block 9 are both smooth, ensuring that the limiting block 9 will not get stuck when moving along the inside of the limiting groove 8.

[0042] Among them, the first motor 10 is fixedly sleeved on the right side of the middle part of the front end of the bracket 1, and the first rotating shaft 11 is fixedly sleeved on the other end of the output shaft of the first motor 10. The outer surface of the first rotating shaft 11 is fixedly sleeved with a rotating rod 12. The left side of the rear end of the rotating rod 12 is movably connected to the front end of the vertical rod 2. A long groove 13 is opened inside the rotating rod 12, and a round block 14 is movably sleeved on the left side inside the long groove 13. The rear end of the round block 14 is fixedly connected to the front end of the slider 7, and the rotating rod 12 will move the round block 14.

[0043] When the first motor 10 is started, the first rotating shaft 11 drives the rotating rod 12 to rotate, so that the inner surface of the long groove 13 generates a thrust on the outer surface of the round block 14, pushing the round block 14 to move downward with the slider 7.

[0044] Among them, a second motor 15 is fixedly installed on the left side of the bottom end of the bracket 1, and the other end of the output shaft of the second motor 15 is fixedly sleeved with a second rotating shaft 16. The top end of the second rotating shaft 16 passes through the bracket 1 and extends to the upper surface of the bracket 1. An active roller 17 is fixedly sleeved in the middle of the outer surface of the second rotating shaft 16, and the active roller 17 is movably sleeved on the left end inside the bracket 1.

[0045] When the second motor 15 is started, the second rotating shaft 16 drives the active roller 17 to rotate.

[0046] Among them, a movable rod 18 is movably sleeved at the right end inside the bracket 1, and a driven roller 19 is fixedly sleeved on the outer surface of the movable rod 18. The driven roller 19 is connected to the active roller 17 through a transmission belt 20. A fixed rod 21 is fixedly sleeved inside the bracket 1. There are four fixed rods 21. Round rollers 22 are movably sleeved on the outer surfaces of the four fixed rods 21. The round rollers 22 are movably sleeved on the inner surface of the bracket 1, and the outer surface of the round roller 22 is movably sleeved on the inner surface of the transmission belt 20.

[0047] The existence of the fixing rod 21 and the round roller 22 will support the transmission belt 20 and prevent the transmission belt 20 from collapsing.

[0048] The working principle and use process of this utility model:

[0049] First, the operator starts the first motor 10, so that the first rotating shaft 11 drives the rotating rod 12 to rotate. At this time, the inner wall of the long groove 13 will generate a thrust on the outer surface of the round block 14, pushing the round block 14 to move with the cross bar 3 through the slider 7 until the height of the iron block detector 6 is matched with the spacing between the raw materials. Then the operator can start the second motor 15, so that the second rotating shaft 16 drives the active roller 17 to rotate. Since the active roller 17 and the driven roller 19 are connected by the transmission belt 20, the transmission belt 20 will rotate. At this time, the transmission belt 20 can transport the raw materials. The mutual cooperation of various mechanisms realizes the adjustment of the height of the iron block detector 6, so that it can be adjusted according to the size of the raw materials and the spacing between the raw materials, thereby improving the detection efficiency of the iron block detector 6.

[0050] When the iron block detector 6 detects that an iron block has passed, the alarm light 405 and the alarm horn 406 will sound an alarm, and the drive motor 501 will start at this time, so that the drive shaft 502 drives the active gear 503 to rotate, thereby causing the driven gear 403 meshing with the active gear 503 to rotate in the opposite direction. As the driven gear 403 rotates, the round rod 402 will rotate along with the alarm light 405 and the alarm horn 406 through the control box 404, thereby realizing a 360-degree all-round alarm of the early warning device, so that operators in different positions can receive the alarm signal in time, thereby improving the alarm range of the early warning device.
