Description

Technical Field

[0001] This utility model relates to the field of vibratory feeding technology, and in particular to a vibratory feeding mechanism for an environmentally friendly fuel pellet mill. Background Technology

[0002] An environmentally friendly fuel pellet mill is a mechanical device that compresses biomass raw materials (such as agricultural and forestry waste, straw, wood chips, etc.) into high-density pellet fuel. When in use, the biomass raw materials need to be fed into the pellet mill by a vibrating feeder.

[0003] A vibrating feeder disclosed in Chinese Patent Publication No. CN221458922U effectively protects workers by incorporating a protective device. This device, which includes a guide plate, prevents workers from being injured while the feeder is feeding sand and gravel, thus improving its practicality, auxiliary function, and protective capabilities. However, according to related technologies and existing technologies, the conveying bucket of this vibrating feeder has a fixed tilt angle. When the input amount of biomass raw materials changes, the conveying speed cannot be adjusted by changing the tilt angle of the conveying bucket. This can easily lead to production efficiency and product quality being affected by excessively fast or slow feeding speeds. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a vibrating feeding mechanism for an environmentally friendly fuel pellet mill.

[0005] The purpose of this utility model is achieved through the following technical solution: a vibrating feeding mechanism for an environmentally friendly fuel pellet mill, including a support frame, an adjusting frame hinged to the top of the support frame, a conveying hopper elastically mounted on the top of the adjusting frame, two vibrating motors fixedly mounted on the top of the conveying hopper, an adjusting component for adjusting the tilt angle of the adjusting frame fixedly mounted on the support frame below the adjusting frame, a dust cover fixedly mounted on one side of the adjusting component, a driving component for driving the adjusting component inside the dust cover, a self-locking component for locking the driving component mounted on the driving component, and a control component for changing the state of the self-locking component at one end of the driving component near the self-locking component.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0026] like Figures 1 to 8As shown, a vibrating feeding mechanism for an environmentally friendly fuel pellet mill includes a support 1. An adjusting frame 2 is hinged to the top of the support 1. A conveying hopper 3 is elastically mounted on the top of the adjusting frame 2. Two vibrating motors 4 are fixedly mounted on the top of the conveying hopper 3. An adjusting component 5 for adjusting the tilt angle of the adjusting frame 2 is fixedly mounted on the support 1 below the adjusting frame 2. A dust cover 9 is fixedly mounted on one side of the adjusting component 5. A drive component 6 for driving the adjusting component 5 is located inside the dust cover 9. A self-locking component 8 for locking the drive component 6 is mounted on the drive component 6. A control component 7 for changing the state of the self-locking component 8 is located at the end of the drive component 6 near the self-locking component 8. In use, biomass raw materials fall into the high position of the conveying hopper 3. At this time, the vibrating motors 4 drive the conveying hopper 3 to vibrate under the support of the adjusting frame 2, pushing the biomass raw materials towards the conveying hopper 3. The conveyor bucket 3 transports the biomass feed into the pellet mill's feed inlet. When the biomass feed changes, the control component 7 is rotated to unlock the drive component 6 via the self-locking component 8. Applying force to the control component 7 then causes the drive component 6 to control the adjustment component 5, which in turn pushes the adjustment frame 2 to rotate around the hinge center between the adjustment frame 2 and the support 1. This changes the tilt angle of the conveyor bucket 3. When the biomass feed is large, the tilt angle is reduced to slow the conveying speed; when the biomass feed is small, the tilt angle is increased to speed up the conveying speed, thus ensuring the stability of the feed into the pellet mill. Once the adjustment is complete and the force is stopped, the self-locking component 8 automatically resets and relocks the drive component 6, preventing it from loosening due to vibration and affecting the stability of the device.

[0027] like Figure 1 and Figure 2 As shown, the adjusting assembly 5 includes a slide 51 fixed to the support 1, a slide seat 52 slidably mounted on the slide 51, a lead screw 53 rotatably mounted through the slide seat 52 at the middle position of the slide 51, the slide seat 52 and the lead screw 53 are threadedly connected, two push rods 54 are hinged on the slide seat 52, and a hinge seat 55 is hinged to the top of the two push rods 54. The hinge seat 55 is fixed to the bottom of the adjusting frame 2. The rotation of the lead screw 53 will push the slide seat 52 to move along the slide 51, and the slide seat 52 will push the adjusting frame 2 to rotate around the hinge center between the adjusting frame 2 and the support 1 through the push rods 54 and the hinge seat 55, thereby changing the tilt angle of the conveying bucket 3. When the biomass raw material input is large, the tilt angle is reduced and the conveying speed is slowed down. When the biomass raw material input is small, the tilt angle is increased and the conveying speed is accelerated, thereby ensuring the stability of feeding material into the pellet mill.

[0028] like Figure 3As shown, the drive assembly 6 includes two fixed blocks 61 fixed to one side of the carriage 51. A rotating shaft 62 is rotatably mounted between the two fixed blocks 61. The rotating shaft 62 passes through the front fixed block 61. A worm gear 63 is fixedly mounted on the rotating shaft 62. A worm wheel 64, which is fixedly connected to the lead screw 53, is engaged below the worm gear 63. The fixed blocks 61 support the rotating shaft 62 to drive the worm gear 63 to rotate, so that the worm gear 63 engages with the worm wheel 64 to drive the lead screw 53 to rotate.

[0029] like Figures 4 to 8 As shown, the self-locking assembly 8 includes a clutch wheel 82 slidably mounted on the rotating shaft 62. A spring 84 is provided between the clutch wheel 82 and the front fixed block 61. A clutch sleeve 81 is fixedly provided on the slide 51 at a position corresponding to the clutch wheel 82. A control ring 83 is fixedly provided on the front side of the clutch wheel 82. Two control grooves 85 are symmetrically opened at the front end of the control ring 83. The clutch wheel 82 is a bevel gear and meshes with the clutch sleeve 81. The clutch wheel 82 is keyed to the rotating shaft 62. The control grooves 85 are arc-shaped. In the initial state, the spring 84 presses against the clutch wheel 82, keeping it engaged with the clutch sleeve 81, thereby locking the rotating shaft 62 and preventing it from loosening due to vibration, which would affect the stability of the device. During adjustment, the control component 7, under the action of the control groove 85, pushes the control ring 83 to drive the clutch wheel 82 to overcome the resistance of the spring 84 and slide along the rotating shaft 62 away from the clutch sleeve 81, so that the clutch wheel 82 disengages from the clutch sleeve 81, thereby automatically releasing the lock on the rotating shaft 62 and facilitating adjustment.

[0030] like Figures 4 to 8 As shown, the control component 7 includes a handle 71 rotatably mounted on the front end of the rotating shaft 62. A grip 72 is fixedly provided at the bottom of the handle 71. Top posts 73 are fixedly provided at positions corresponding to the two control slots 85 on the handle 71. Two limiting plates 74 are fixedly provided on the upper and lower sides of the top posts 73 on the rotating shaft 62. The end of the top post 73 that contacts the control slot 85 is spherical. When the biomass feed input changes, the handle 71 is rotated by the grip 72, causing the handle 71 to drive the top posts 73 to rotate around the rotating shaft 62. The movement continues until the top post 73 contacts the limit plate 74 and can no longer move. During this process, the top post 73 will push the control ring 83 under the action of the control groove 85, causing the clutch wheel 82 to overcome the resistance of the spring 84 and slide along the rotating shaft 62 away from the clutch sleeve 81, so that the clutch wheel 82 disengages from the clutch sleeve 81, thereby automatically releasing the lock on the rotating shaft 62. At this time, force is applied to the rotating handle 71, and the rotating handle 71 will drive the rotating shaft 62 to rotate through the top post 73 and the limit plate 74, controlling the adjustment of the tilt angle.

[0031] The work process is as follows:

[0032] S1: As Figure 1As shown, when in use, the biomass raw material falls into the high part of the conveying bucket 3. At this time, the vibrating motor 4 drives the conveying bucket 3 to vibrate under the support of the adjusting frame 2, conveying the biomass raw material to the low part of the conveying bucket 3 and feeding it into the feed inlet of the pellet mill.

[0033] S2: As Figures 6 to 8 As shown, when the biomass feed input changes, the handle 72 rotates the handle 71, causing the handle 71 to drive the top column 73 to rotate around the shaft 62 until the top column 73 contacts the limiting plate 74 and can no longer move.

[0034] S3: As Figures 6 to 8 As shown, during this process, the top column 73 will push the control ring 83 under the action of the control groove 85, which will drive the clutch wheel 82 to overcome the resistance of the spring 84 and slide along the rotating shaft 62 away from the clutch sleeve 81, so that the clutch wheel 82 disengages from the clutch sleeve 81, thereby releasing the lock on the rotating shaft 62.

[0035] S4: As Figures 1 to 4 As shown, when force is applied to the handle 71, the handle 71 will drive the shaft 62 to rotate through the top column 73 and the limiting plate 74, causing the shaft 62 to drive the worm 63 to rotate. The worm 63 then meshes with the worm wheel 64 to drive the lead screw 53 to rotate, thereby pushing the slide 52 to move along the slide frame 51. The slide 52 then pushes the adjusting frame 2 to rotate around the hinge center between the adjusting frame 2 and the support 1 through the push rod 54 and the hinge seat 55, thereby causing the conveying bucket 3 to change its tilt angle.

[0036] S5: As Figure 1 and Figure 2 As shown, when the input amount of biomass raw materials is large, the tilt angle is reduced and the conveying speed is slowed down; when the input amount of biomass raw materials is small, the tilt angle is increased and the conveying speed is accelerated, thereby ensuring the stability of feeding materials into the pellet mill.

[0037] S6: As Figure 7 and Figure 8 As shown, when the adjustment is completed and the force is stopped, the spring 84 will be released, thereby pushing the clutch wheel 82 to reset and re-engage with the clutch sleeve 81, thereby re-locking the rotating shaft 62, realizing the self-locking of the rotating shaft 62, and preventing it from loosening due to vibration, which would affect the stability of the device.

[0038] The vibration motor 4 in this application is a well-known technology in this field, therefore its specific structure and working principle are not described in detail.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
