Technical Field

[0001] The invention relates to the technical field of belt systems, and in particular to a belt system material blocking prevention device. Background Art

[0002] The material conveying process now requires the use of a belt system for transportation. When the belt system cooperates with the chute, the material inside the chute is prone to accumulation and friction with the belt when it continues to accumulate. Therefore, it is necessary to provide effective anti-blocking reminders for the belt system.

[0003] After searching, the announcement number CN218578851U discloses a belt conveyor head chute anti-blocking device and a coking coal conveying system. The device installs a high-frequency vibration detector on the side wall of the chute, and judges the height of the material in the chute by the amplitude of the vibration probe at the end of the high-frequency vibration detector.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The embodiment of the invention discloses a belt system material blocking prevention device.

[0030] The present invention provides Figure 1-4The belt system anti-blocking device shown comprises a support frame 1 and a belt frame 2 arranged at the upper end of the support frame 1, a support plate 3 is fixedly arranged at the upper end of the outer wall of the support frame 1, a rotating rod 4 is rotatably penetrated inside the support plate 3, and the rotating rod 4 is fixedly connected to the belt frame 2. When the belt frame 4 is pushed, it can rotate under the support of the rotating rod 4 and the support plate 3, so as to effectively protect the belt frame 4;

[0031] A bottom plate 5 is fixedly provided at the lower end of the outer wall of the support frame 1, a chute 6 is placed on the top of the bottom plate 5, a plurality of internal thread discharge holes are opened at the bottom of the chute 6, and an external thread sealing plate 29 is penetrated through the internal threads of the internal thread discharge holes. The chute 6 can be separated from the bottom plate 5, and the material inside the chute 6 can be discharged from the mobile phone through the setting of the internal thread discharge holes;

[0032] A push ring 7 is placed inside the chute 6, a guide ring 21 is fixed on the top of the push ring 7, the inner wall of the guide ring 21 is inclined, and two symmetrically arranged floating columns 8 are fixed on the bottom of the push ring 7. A push ring 9 is slidably penetrated through the outer wall of the chute 6, and a connecting rod 10 is provided between the push ring 9 and the push ring 7. As the amount of material inside the chute 6 increases, the push ring 7 is pushed by the material and drives the push ring 9 to move upward, so that the push ring 9 pushes the belt frame 4, so that the belt frame 4 is away from the material and the belt is worn;

[0033] A horizontal plate 11 is fixedly provided at the lower end of the inner wall of the push ring 7, a vertical rod 12 is fixedly provided at the top of the horizontal plate 11, a cleaning push plate 14 is fixedly provided on the rod wall of the vertical rod 12 through a connecting rod 13, a cavity is opened at the bottom of the chute 6, a motor 15 is fixedly provided in the cavity, the output shaft of the motor 15 passes through the chute 6 and is fixedly provided with a telescopic rod 16, the telescopic rod 16 is a square telescopic rod, the top of the telescopic rod 16 is fixedly connected to the vertical rod 12, the vertical rod 12 and the output shaft of the motor 15 are fixedly sleeved with a connecting plate 27 at one end close to each other, a corrugated protective tube 28 is fixedly provided between the two connecting plates 27, during the material receiving process, the motor 15 drives the vertical rod 12 to rotate, and enables the cleaning retreat plate 14 to clean the material sticking to the inner wall of the push ring 7, and at the same time makes the material leveled without exceeding the push ring 7, thereby ensuring the stable upward movement of the push ring 7.

[0034] In order to be able to shut down the belt system when the material gradually increases, try to avoid material blockage, such as Figure 1As shown, a guide plate 17 is fixedly provided on the upper end of the outer wall of the support frame 1, and a pressure rod 18 is slidably penetrated inside the guide plate 17. The pressure rod 18 is fixedly connected to the outer wall of the belt frame 2. A guide groove is opened inside the guide plate 17, and a pressure sensor 19 is fixedly provided on the top of the inner wall of the guide groove. The pressure rod 18 is slidably arranged in the guide groove and is arranged in cooperation with the pressure sensor 19. As the belt frame 4 is pushed and moves upward, the pressure rod 18 slides in the guide plate 17 and squeezes the pressure sensor 19, so that the pressure sensor 19 receives the pressure signal and closes the belt frame 4 through the external control device, so that the belt frame 4 stops working and the material is no longer transmitted, so as to avoid the material blockage in the chute 6 as much as possible;

[0035] A buffer spring 20 is provided at the inner lower end of the guide groove, and the bottom of the buffer spring 20 is fixedly connected to the bottom of the inner wall of the guide groove. The arrangement of the buffer spring 20 can enable the belt frame 4 to stably move back to the original position.

[0036] In order to determine the material receiving position of the chute 6 and facilitate the taking of the chute 6, Figure 3-4 As shown, a placement groove 22 is provided at the top of the bottom plate 5, a cross bar 23 is rotatably penetrated inside the placement groove 22, a baffle 24 is fixedly provided on the rod wall of the cross bar 23, and the baffle 24 can block the end of the placement groove 22 to determine the placement position of the chute 6;

[0037] The baffle 24 is arranged in the placement groove 22 and is matched with the chute 6. A limiting ring 25 is sleeved on the end of the cross bar 23. The limiting ring 25 is fixedly connected to the outer wall of the bottom plate 5. A clamping bolt 26 is threaded through the side of the limiting ring 25. The end of the clamping bolt 26 is matched with the rod wall of the cross bar 23. The clamping bolt 26 locks the cross bar 23, so as to fix the position of the baffle 24.

[0038] Working principle: When the material is conveyed by the belt system, the chute 6 is placed on the top of the bottom plate 5 and supported by the baffle 24. At this time, the floating column 8 supports the push ring 7 and is set under the chute 6. Then the belt frame 4 is started so that the material can be conveyed into the chute 6. As the material flows in, the motor 15 is started and the vertical rod 12 is driven to rotate through the telescopic rod 16. Under the support of the connecting rod 13, the cleaning push plate 14 is used to scrape off the material adhering to the inner wall of the push ring 7. At the same time, when the push ring 7 is pushed up by the material, the material inside the push ring 7 can be leveled to avoid the material from exceeding the push ring 7 as much as possible, so that the push ring 7 can be pushed by the continuously increasing 3 materials and move up stably. When the push ring 7 moves upward, the push ring 9 moves upward stably through the support of the connecting rod 10, and begins to push the belt frame 4, so that the belt frame 4 begins to swing under the rotation support of the rotating rod 3 and the support plate 4. As the belt frame 4 swings, the pressure rod 18 slides in the guide groove and gradually approaches the pressure sensor 19. When the pressure rod 18 squeezes the pressure sensor 19, the pressure sensor 19 receives the pressure signal and closes the belt frame 4 through an external control device, so that the belt frame 4 stops working and the material is no longer transmitted, and the material inside the chute 6 is avoided as much as possible. At this time, because the belt frame 4 is continuously pushed and away from the material, the belt inside the belt frame 4 cannot be worn by the friction of the material, thereby improving the stability of the belt system.

[0039] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
