[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a material loosening device and material conveying equipment, which includes a conveyor and a material loosening device, with the material loosening device being disposed on the conveyor. The material loosening device includes a loosening assembly and a drive structure. The loosening assembly includes an eccentric disc 20, a steering push rod 30, and a loosening member 40. The first end of the steering push rod 30 is rotatably connected to the eccentric disc 20, and the loosening member 40 is rotatably connected to the second end of the steering push rod 30. The connection between the steering push rod 30 and the eccentric disc 20 maintains a preset eccentricity with the center of the eccentric disc 20. The drive structure drives the eccentric disc 20 to rotate about the center of the eccentric disc 20 and drives the loosening member 40 to move through the steering push rod 30.
[0034] By setting up a material loosening device in conjunction with a conveyor, the conveyor transports the material. The material loosening device can loosen and spread the material on the conveying structure during the conveying process. Specifically, when the eccentric disc 20 rotates, the loosening part 40 is pulled by the steering push rod 30, so that the loosening part 40 moves in an arc trajectory, thereby achieving uniform loosening of the material in the horizontal and vertical directions, and flattening the material, ensuring the uniformity of material feeding and the consistency of material stacking height, and effectively improving the drying effect.
[0035] Optionally, the conveyor is a vibrating conveyor. A vibrating conveyor may use an exciter as a vibration source, which vibrates the trough, causing the material in the trough to slide or toss in a certain direction to complete continuous conveying. A vibrating conveyor may also use an electric motor or a vibrating motor as a vibration source and use a conveyor belt to convey the material.
[0036] Reference Figure 1 Taking carrying surface A as an example, the material is transported by the conveyor structure of the conveyor and placed on carrying surface A of the conveyor structure. The loosening member 40 is located above carrying surface A and maintains a certain distance from carrying surface A. The material is specifically wet, lumpy cut stem material. In other embodiments, the material loosening device can also be used to loosen and flatten other materials, such as reconstituted cut stem material. Reconstituted cut stem is a product made by combining tobacco leaves or plant materials with tobacco stems or other plant materials through a specific process.
[0037] In this embodiment, the conveyor is a high-frequency vibration conveyor, and the vibration frequency of the high-frequency vibration conveyor is above 100 Hz. By setting up a high-frequency vibration conveyor, the high-frequency vibration conveyor has the characteristics of strong excitation force, low vibration noise, and high efficiency. The vibration of the high-frequency vibration conveyor helps loosen the material, and the specific structure of the conveyor can be set with reference to the existing technology.
[0038] Optionally, the steering push rod 30 includes an electrically operated telescopic push rod. By providing an electrically operated telescopic push rod as the steering push rod 30, the length of the steering push rod 30 is adjustable, thereby facilitating adjustment of the range of action of the material loosening device for loosening and leveling the material. The steering push rod 30 may also be a telescopic sleeve structure, which can be manually adjusted to change the overall length.
[0039] To achieve a better loosening effect, multiple loosening assemblies are provided, and the driving structure can simultaneously drive all eccentric discs 20 to rotate; or, multiple loosening assemblies are provided, and the driving structures and loosening assemblies are provided one-to-one. By providing multiple loosening assemblies for simultaneous use, the multiple loosening assemblies cooperate and loosen the material at different locations, effectively improving the loosening and leveling effect of the material.
[0040] When there is only one loose component, the driving structure only drives one eccentric disc 20 to rotate; when there are multiple loose components, the eccentric discs 20 of multiple loose components can be driven by the same driving structure, or multiple driving structures can be provided to drive them separately.
[0041] Optionally, the material loosening device further includes a rotating shaft 11, and an eccentric disc 20 is rotatably connected to the drive structure via the rotating shaft 11, and the eccentric disc 20 is detachably connected to the rotating shaft 11. By providing a detachable connection between the eccentric disc 20 and the rotating shaft 11, eccentric discs 20 of different sizes can be installed, thereby changing the size of the preset eccentric distance, and further changing the range of the material loosening device for loosening and leveling the material.
[0042] Optionally, the material loosening device further includes a belt, at least two loose components are provided, the rotating shafts 11 are provided in a one-to-one correspondence with the loose components, and the drive structure is connected to all the rotating shafts 11 via the belt. By providing the belt, the drive structure connects the rotating shafts 11 of at least two loose components via the belt, thereby forming a linkage structure. Only one drive structure is required to drive the rotating shaft 11 of one loose component to rotate, and the belt can drive the rotating shafts 11 of other loose components to rotate synchronously. That is, the same drive structure can simultaneously control the rotation of the rotating shafts 11 of at least two loose components, resulting in a compact structure and easy control.
[0043] Specifically, the drive structure includes a motor 12, which is used to drive the eccentric disc 20 to rotate. By setting a separate drive structure, the material loosening device will not affect the normal operation of the conveyor. In this embodiment, the motor 12 is connected to the eccentric disc 20 through the rotating shaft 11.
[0044] In other embodiments, the motor 12 and the eccentric disc 20 can be directly connected and fixed together using a keyway or a pin; the motor 12 and the eccentric disc 20 can also be connected by a shaft sleeve, which is installed on the output shaft of the motor 12 and inserted into the center hole of the eccentric disc 20; the motor 12 and the eccentric disc 20 can also be connected by a coupling. The coupling has a good shock-absorbing effect, can reduce the vibration and noise of the eccentric disc 20, can withstand a certain degree of axial, radial and angular deviation, and can also facilitate maintenance and replacement.
[0045] See also Figure 2 The loose parts 40 include a cross bar 41 and a plurality of rake nails 42. The cross bar 41 is rotatably connected to the steering push rod 30, and the rake nails 42 are detachably connected to the cross bar 41. The rake nails 42 are made of stainless steel.
[0046] In this embodiment, the crossbar 41 is in a straight line shape. The center of the top of the crossbar 41 is connected to the steering push rod 30. The bottom of the crossbar 41 is provided with a plurality of rake nails 42 in parallel. The rake nails 42 are cylindrical and can be fixed to the crossbar 41 by screws. The provision of detachable rake nails 42 allows the installation of rake nails 42 of different lengths according to actual conditions, which has strong applicability. The use of stainless steel material for the rake nails 42 makes it less likely for materials to get stuck and accumulate, and facilitates maintenance.
[0047] Optionally, to enhance the flexibility of the loose member 40, a chute is provided at the top of the crossbar 41, and the second end of the steering push rod 30 is rotatably disposed within the chute and is capable of sliding within the chute. By providing the chute at the top of the crossbar 41, the crossbar 41 and the steering push rod 30 can both rotate and slide relative to each other, making the loose member 40 more flexible to use.
[0048] In this embodiment, a conveyor and a material loosening device are used in combination. The conveyor transports the material, and the material loosening device is driven independently without affecting the normal operation of the conveyor. The material loosening device can loosen and spread the material on the conveying structure during the conveying process; the movement of the loose parts 40 can achieve lateral loosening of the material. Due to the provision of the eccentric disc 20, the loose parts 40 can longitudinally evenly distribute the material, ensuring that the material can be evenly flattened before entering the drying equipment, effectively improving the uneven material feeding and inconsistent stacking heights, ensuring that the material is evenly flattened, and having a better loosening and even effect; and by adjusting the height of the loose parts 40, the size of the eccentric disc 20 and the length of the steering push rod 30, the range of the longitudinal and transverse spreading of the material can be changed, and the thickness of the flattened material can also be changed, thereby improving applicability.
[0049] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
