Technical Field

[0001] This invention belongs to the technical field of material conveying equipment, and specifically relates to a material conveying equipment capable of monitoring blockages. Background Technology

[0002] Material handling in factories is primarily accomplished using conveyors, which generally only transport materials. However, blockages during operation can prevent materials from being transported normally, and in severe cases, can damage the conveyor. If the conveyor is stopped and repaired as soon as a blockage occurs, not only is the workload reduced, but the conveyor is also largely protected. Therefore, continued improvement of existing conveyors is necessary. Summary of the Invention

The small gear is connected to the pointer of the pressure gauge through a connecting rod.

[0006] As a preferred embodiment of the present invention, the bracket is provided with an upper roller clamping cover plate and a lower roller clamping cover plate, and the large gear is located between the upper roller clamping cover plate and the lower roller clamping cover plate.

[0019] Example 1

[0020] like Figure 1 As shown, a material conveying device capable of blockage monitoring according to the present invention includes a conveying pipe 1, a screw rod 3 is provided inside the conveying pipe 1, one end of the screw rod 3 is connected to the drive end of a motor 2, and a pressure gauge 4 is provided at the top of the conveying pipe 1.

[0021] Combination Figure 2 Start motor 2, which drives screw rod 3. Screw rod 3 conveys the material in conveying pipe 1. If blockage occurs, conveying pipe 1 will deform. After deformation, the pressure will be detected by pressure gauge 4. When the pressure of pressure gauge 4 reaches the set value, it can be judged that a blockage has occurred. At this time, the staff can check the conveying system to determine whether the situation is true.

[0022] Example 2

[0023] like Figure 3 and Figure 4 As shown, unlike Embodiment 1, in a material conveying device for monitoring blockages according to the present invention, a support 7 is provided below the pressure gauge 4. A large gear 13 and a small gear 15 meshing with the large gear 13 are rotatably arranged inside the support 7. An arc-shaped track is provided on the inner ring of the large gear 13, and a push rod 12 is fitted onto the inner ring of the large gear 13. An arc-shaped groove matching the arc-shaped inner track is provided on the outside of the push rod 12. The small gear 15 is connected to the pointer 20 of the pressure gauge 4 via a connecting rod 14. An upper roller clamping cover plate 10 and a lower roller clamping cover plate 11 are provided on the support 7, and the large gear 13 is located between the upper roller clamping cover plate 10 and the lower roller clamping cover plate 11. Multiple round rollers 17 are arranged in the roller tracks engraved on both sides of the large gear 13 via round roller frames 18.

[0024] During operation, the push rod 12 contacts the top of the conveying pipe 1. If the pipe is blocked, as the blockage worsens, the blockage will accumulate and press outward on the conveying pipe 1, causing the top of the conveying pipe 1 to bulge outward and deform. This will then exert an outward pushing force on the push rod 12. The upper roller clamping cover plate 10 and the lower roller clamping cover plate 11 are both fixed on the bracket 1. The large gear 13 is limited by the upper roller clamping cover plate 10 and the lower roller clamping cover plate 11, so that the large gear 13 can only rotate and cannot move up and down. The limiting principle of the large gear 13 is as follows: the roller tracks engraved on both sides of the large gear 13 allow the round roller 17 to rotate and slide only in the roller tracks. The round roller bracket 18 acts as a support to limit the round roller 17. Both round roller brackets 18 on both sides are in contact with the upper roller pressing cover plate 10 or the lower roller pressing cover plate 11, thereby limiting the large gear 13 between the upper roller pressing cover plate 10 and the lower roller pressing cover plate 11.

[0025] Example 3

[0026] Combination Figure 5 and Figure 6Unlike Embodiment 2, in a material conveying device capable of blockage monitoring according to the present invention, an alarm light 5 and an alarm 6 are provided on the support 7; a contact base 8 is provided between the alarm light 5 and the alarm 6, and a four-sided copper contact 16 is provided inside the contact base 8. The upper end of the push rod 12 extends into the contact base 8. A spring 9 is provided at the upper end of the push rod 12, and the upper end of the spring 9 presses against the lower edge of the contact base 8.

[0027] Push rod 12 is pushed outward, causing the upper end of the push rod to compress and deform the elastic four-sided copper contact 16. The elastic four-sided copper contact 16 is placed in the contact base 8. When the blockage is no longer present, the return spring 9 will reset the push rod 12. The copper contact 19 is connected to the power supply, alarm light 5, and alarm 9, forming a conductive series circuit. After the elastic four-sided copper contact 16 is deformed by the pressure of the push rod 12, it contacts the copper contact 19 on both sides, forming a circuit loop. The alarm 9 sounds, and the alarm light 5 flashes. When the blockage is cleared, the pressure disappears, the push rod 12 returns to its original position under the action of the return spring, and the circuit is disconnected.

[0028] Combination Figure 7 Since the large gear can only rotate, the internal helical teeth of the large gear 13 mesh in the helical tooth slide outside the push rod 12. As the push rod 12 pushes, the large gear 13 rotates along the helical tooth slide, which in turn drives the small gear 15 to rotate, which in turn drives the rotating shaft 14 and pointer 10 of the pressure gauge 4 to rotate. The rotating shaft 14 of the pressure gauge is connected to the small gear 15 with a key. The slight push of the push rod 12 will be reflected on the pressure gauge 8 through calculation.

[0029] Therefore, compared with the prior art, the material conveying equipment of the present invention, which can monitor blockages, can determine whether the conveyor is blocked based on pressure, so that staff can maintain the equipment in a timely manner and extend its service life. Furthermore, the material conveying equipment of the present invention, which can monitor blockages, has a simple overall structure, is easy to operate, and has low manufacturing costs, making it a promising candidate for market promotion and application.
