DETAILED DESCRIPTION
[0020] 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 technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 4The utility model provides a technical solution: a spiral conveying device for avoiding material jamming, comprising a base 1, the top of the base 1 is rotatably connected to one end of a conveying trough 2, the other end of the conveying trough 2 is connected to the top of the base 1 through a hydraulic cylinder 3 opened on both sides thereof, a driving pulley 4 is installed on one side of the base 1 through the output end of a servo motor, the driving pulley 4 is connected to a driven pulley 5 through a belt, a spiral feeding rod 6 is opened inside the conveying trough 2, the shaft head at one end of the spiral feeding rod 6 passes through the axis of the driven pulley 5 and is welded to it as a whole, a lower hopper 7 and a discharge pipe 8 are respectively opened at the top of one end of the conveying trough 2 and the bottom of the other end, the lower hopper 7 is on the same side as the driving pulley 4, a first baffle 9 and a second baffle 10 are respectively opened inside the lower hopper 7, the first baffle 9 is located above the second baffle 10, a vibrating material assembly 11 is respectively opened at the bottom of the first baffle 9 and the second baffle 10, and an inner sleeve 12 is installed inside the discharge pipe 8.
[0022] The inner sleeve 12 includes a first adjusting tube 1201 and a second adjusting tube 1202. The discharge tube 8 is glued to the outer walls of the first adjusting tube 1201 and the second adjusting tube 1202 through springs distributed in an annular manner on its inner wall. One end of the second adjusting tube 1202 is slidably connected to the interior of the first adjusting tube 1201.
[0023] In this embodiment, Figure 1 and Figure 3 As shown, one end of the conveying trough 2 forms a lifting structure on the surface of the base 1 through the hydraulic cylinder 3, and the spiral feed rod 6 forms a rotating structure inside the conveying trough 2 through the active pulley 4 and the driven pulley 5; one end of the conveying trough 2 can be driven and lifted by the hydraulic cylinder 3, thereby adjusting the height of the discharge pipe 8 from the ground, which can better adapt to and connect with external material receiving containers of different specifications. The flow state of the material during discharge can be optimized through the height adjustment method to ensure its smooth conveying path.
[0024] In this embodiment, Figure 4As shown, the top and bottom of the conveying trough 2 are respectively provided with through holes which are connected with the lower hopper 7 and the discharge pipe 8, and the first regulating pipe 1201 and the second regulating pipe 1202 form an elastic reset structure through the spring on the inner wall of the discharge pipe 8, and an opening and closing structure is formed between the first regulating pipe 1201 and the second regulating pipe 1202, and at the same time, the minimum distance between the first regulating pipe 1201 and the second regulating pipe 1202 is consistent with the diameter of the through hole which is connected with the bottom of the conveying trough 2 and the discharge pipe 8; at present, the discharge pipe 8 at the bottom of most spiral-structured feeding equipment is a fixed structure. When the material is discharged, if part of the raw materials are unevenly crushed, they will be stuck on the inner wall of the pipe mouth, thereby hindering the orderly transportation of the material. When the material is stuck, the inner sleeve 12 can be telescopically adjusted under the action of the spring to try to change the size of its discharge, which can effectively alleviate the material jam. The telescopic effect achieved by the elastic structure can timely adjust the discharge state of the material through this telescopic action to avoid the continuous accumulation of stuck materials and cause more serious blockage.
[0025] In this embodiment, Figure 2 As shown, the vibrating material assembly 11 is composed of cams, and the cams are coaxially connected, and the vibrating material assemblies 11 are connected by a belt opened in a cavity on one side of the discharge hopper 7; the structure of the vibrating material assembly 11 helps to assist in material discharge, and helps the materials that fall on the surface of the first baffle 9 and the second baffle 10 to be discharged smoothly and orderly into the conveying trough 2, making the material discharge process more proactive and controllable, and also effectively avoiding the phenomenon that the first baffle 9 and the second baffle 10 prevent the material from being accumulated on its surface while preventing it from being too fast.
[0026] In this embodiment, Figure 2 As shown, the lower hopper 7 is wide at the top and narrow at the bottom, and the first baffle 9 and the second baffle 10 are relatively distributed up and down and fit to the inner wall of the lower hopper 7 at an angle of 15°; the structure of the first baffle 9 and the second baffle 10 effectively prevents the material inside the lower hopper 7 from falling too fast, thereby causing blockage and jamming inside the conveying trough 2. The first baffle 9 and the second baffle 10 play a certain guiding and combing role on the material entering the lower hopper 7, so that the material always maintains an orderly conveying link.
[0027] In this embodiment, Figure 2As shown, a spring is installed at one end of the bottom of the first baffle 9 and the second baffle 10, and one end of the first baffle 9 and the second baffle 10 is connected to the inner wall of the lower hopper 7 through a spring connection, and one end of the first baffle 9 and the second baffle 10 forms a reciprocating swing mechanism through a spring and a vibrating material assembly 11; the spring structure at the bottom of the first baffle 9 and the second baffle 10 can absorb and reduce a certain impact force when the material impacts the surface of the first baffle 9 and the second baffle 10 during the falling process, thereby extending the service life of the first baffle 9 and the second baffle 10, and secondly, its elastic structure can make the first baffle 9 and the second baffle 10 reset again after being pressurized by the material, so as to continue to play its function of assisting material discharge, thereby achieving uniformity and smoothness of material transportation inside the lower hopper 7, and effectively avoiding material blockage or jamming inside the lower hopper 7.
[0028] The use method and advantages of the utility model: The working process of the spiral conveying device for avoiding material jamming is as follows when in use:
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the production personnel put a large amount of raw materials that need to be transported into the lower hopper 7. Since the lower hopper 7 is a structure that is wide at the top and narrow at the bottom, the speed of the material falling can be slowed down. The material falls on the top of the first baffle 9 in advance, and slides to the surface of the second baffle 10. At the same time, in the process, by adjusting the number of revolutions of the servo motor, the cam assembly in the vibrating assembly 11 can maintain a uniform rotation under the first baffle 9 and the second baffle 10 respectively, and intermittently push the first baffle 9 and the second baffle 10, so that the material can be smoothly and orderly merged from the bottom of the lower hopper 7 into the inside of the conveying trough 2. The spring structure at the bottom of the first baffle 9 and the second baffle 10 can absorb and reduce a certain impact force when the material impacts the surface of the first baffle 9 and the second baffle 10 during the falling process, thereby extending the service life of the first baffle 9 and the second baffle 10. Secondly, its elastic structure can make the first baffle 9 and the second baffle 10 reset again after being pressed by the material, so as to continue to play its auxiliary function of material discharge, thereby realizing the uniformity and smoothness of material transportation in the lower hopper 7. When the material falls into the conveying trough 2, the active pulley 4 drives the driven pulley 5 to rotate the spiral feed rod 6 through the belt under the drive of the external servo motor. The material entering the conveying trough 2 will be pushed forward by the spiral blades on the surface of the rotating spiral feed rod 6 and discharged through the outlet intersecting with the discharge pipe 8. When the material is discharged from the outlet, if some raw materials are broken unevenly and too large, the first adjusting tube 1201 and the second adjusting tube 1202 will be telescopically adjusted correspondingly due to the sliding structure and the external spring structure, trying to change the size of the discharge, so that the raw material is discharged from the expanded inner sleeve 12 and discharged from the discharge pipe 8 into the external collection container. The telescopic energy achieved by the elastic structure can timely adjust the discharge state of the material through this telescopic action to avoid continuous accumulation of stuck materials and cause more serious blockage. At the same time, the telescopic structure of the hydraulic cylinder 3 can make one end of the conveying trough 2 rise and fall, thereby adjusting the height of the discharge pipe 8 from the ground, which can better adapt to and connect with external material receiving containers of different specifications.

Technical staff in this industry should understand that the utility model is not limited by the above embodiments.
