Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, and particularly relates to an automatic hook - detaching device. Background Technique

[0002] A belt conveyor, usually referring to a belt conveyor machine, is a mechanical device for material transportation. It conveys materials from one point to another through a continuous belt. During the use of the belt conveyor, a cleaner is usually used to clean the surface of the belt conveyor.

[0003] At present, during the use of the reciprocating cleaner of the belt conveyor, since the goods in the aggregate chute cannot be completely cleaned in one pass during the cleaning process by the scraper, when the scraper returns, the goods are brought back to the tail of the aggregate chute. Over time, more aggregates accumulate at the tail, requiring workers to climb up to clean it. Eventually, the goods are still swept onto the ground, reducing the cleaning effect and wasting labor.

[0004] Therefore, we propose an automatic hook - detaching device to solve the above - mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic hook - detaching device to solve the problem in the above - mentioned background technique that the goods in the aggregate chute cannot be completely cleaned in one pass during the cleaning process by the scraper, reducing the cleaning effect and wasting labor.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1: Please refer to Figure 1 、 Figure 2 and Figure 3 , an automatic hook - detaching device, including an aggregate chute 1 and a cleaning frame 2 arranged at the upper end of the aggregate chute 1. A hook member 3 is arranged on one side of the cleaning frame 2, a connecting rod 4 is arranged inside the cleaning frame 2, a hinge seat 5 is arranged on one side of the connecting rod 4, and a scraper 6 for cleaning is rotatably connected inside the hinge seat 5. The scraper 6 can clean the materials.

[0024] A scraper bracket 61 is arranged on the surface of the scraper 6. One end of the scraper bracket 61 is connected with a bracket roller 62. An inclined bracket 63 is installed at the front end of the aggregate chute 1. A hook ring 64 is also arranged on the surface of the scraper 6. During the traction process of the winch, when the bracket roller 62 touches the inclined bracket 63, it moves uphill. Since the scraper bracket 61 is installed in a hinge - type movable state, it is slowly lifted at this time.

[0025] The hook member 3 includes a hook body 31 and a baffle 32 arranged at one end of the hook body 31. A spring 33 is also arranged at the end of the hook body 31 away from the baffle 32. The baffle 32 is placed at the rear end of the hook body 31, and the spring 33 is placed at the front end of the hook body 31. The hook body 31 can be adapted to the hook ring 64. The hook body 31 can be hung in the hook ring 64. When the scraper bracket 61 slowly rises to the position of the hook body 31 and through the reverse movement of the winch, the scraper bracket 61 slowly descends and finally the hook ring 64 automatically falls onto the hook body 31, realizing automatic hooking.

[0026] The hook member 3 further includes a mounting seat 34 and a cylinder member 35 disposed on one side of the mounting seat 34. A fixed bracket 36 is connected to the telescopic end of the cylinder member 35. When the cylinder member 35 is activated, it can push the fixed bracket 36 to move towards the hook body 31, causing one end of the hook body 31 to move away from the hook ring 64, achieving the purpose of unhooking.

[0027] In this embodiment: During the winch traction process, the bracket roller 62 moves uphill when it touches the inclined bracket 63. Since the scraper bracket 61 is installed in a hinged and movable state, it is slowly lifted at this time. During the slow lifting process of the scraper bracket 61, it reaches the position of the hook body 31, ensuring that the hook body 31 is under the tension of the spring 33 and always in the hooked mode. Through the reverse movement of the winch, the scraper bracket 61 slowly descends and finally the hook ring 64 automatically falls onto the hook body 31, realizing automatic hooking. When the cylinder member 35 is activated, it can push the fixed bracket 36 to move towards the hook body 31, causing one end of the hook body 31 to move away from the hook ring 64, achieving the purpose of unhooking. The hook body 31 disengages from the fixed bracket 36 and is under the operation of the spring 33's tension, and is again in the hooked mode, avoiding the scraper 6 from bringing the material back to the tail of the aggregate chute during the return journey, reducing the wear of the scraper 6, avoiding manual cleaning, and reducing potential safety hazards.

[0028] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 4 , a lubrication structure 7 is provided above the connection between the hinge seat 5 and the scraper 6, and the lubrication structure 7 is used to lubricate the connection between the hinge seat 5 and the scraper 6.

[0029] There are two sets of lubrication structures 7, and the two sets of lubrication structures 7 are symmetrically distributed about the center line of the aggregate chute 1.

[0030] The lubrication structure 7 includes a support ring 71 provided at the upper end of the cleaning frame 2 and a bent pipe 72 provided inside the support ring 71. The lower end of the bent pipe 72 is connected to a spray pipe 73, and the spray pipe 73 is placed above the connection between the hinge seat 5 and the scraper 6.

[0031] The lubrication structure 7 further includes a syringe 74 provided at one end of the bent pipe 72 and a push rod 75 provided inside the syringe 74. The inside of the syringe 74 is filled with lubricating oil. One end of the push rod 75 close to the syringe 74 is connected to a piston block 76, and the piston block 76 is placed inside the syringe 74. When the push rod 75 is pushed, the piston block 76 can move, and the lubricating oil can enter the bent pipe 72 from the syringe 74 and be discharged through the spray pipe 73.

[0032] In this embodiment: The support ring 71 is used to support the elbow pipe 72, and the injection cylinder 74 is hermetically inserted into one end of the elbow pipe 72. Then, when the push rod 75 is pushed, the piston block 76 can move, and the lubricating oil can enter the elbow pipe 72 from the injection cylinder 74 and be discharged through the ejection pipe 73. At this time, the lubricating oil can drip at the connection between the hinge seat 5 and the scraper 6, achieving the lubricating effect and ensuring the smooth rotation of the scraper 6.

[0033] Working principle: During the traction of the winch, when the bracket roller 62 touches the inclined bracket 63, it moves uphill. Since the scraper bracket 61 is installed in a hinge - type movable state, it is slowly lifted at this time. During the slow lifting process of the scraper bracket 61, it reaches the position of the hook body 31, ensuring that the hook body 31 is under the tensile force of the spring 33 and always remains in the hooking mode. Through the reverse movement of the winch, the scraper bracket 61 slowly descends, and finally the hook ring 64 automatically falls onto the hook body 31 to achieve automatic hooking. When the cylinder part 35 is started, it can push the fixed bracket 36 to move towards the hook body 31, so that one end of the hook body 31 moves away from the hook ring 64 to achieve the purpose of unhooking. The hook body 31 is separated from the fixed bracket 36 and operates under the tensile force of the spring 33, and is again in the hooking mode.
