They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.
[0030] Existing additive raw material crushing devices generally use two meshing crushing gears to crush feed additive raw materials. However, this crushing method has two drawbacks. First, it relies solely on the unidirectional rotation of the meshing gears to achieve crushing, resulting in poor crushing effect. Second, the distance between the meshing crushing gears cannot be adjusted, making it difficult to clean after crushing.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an embodiment of the present invention provides a feed additive raw material crushing device, including a crushing box 1, a meshing crushing device 2, a spacing adjustment device 3, a follow-up reciprocating device 4, and an adjustable force application device 5.
[0032] The meshing crushing device 2 is movably installed inside the crushing box 1. It crushes the additive raw materials through the meshing action between two crushing gears. At the same time, the relative sliding between the two crushing gears can increase the shear crushing force. The shear crushing force generated by the relative sliding can further crush the additive raw materials, resulting in a good crushing effect. It includes an active crushing gear 6 and a driven crushing gear 7, which are meshed and connected for the crushing operation of additive raw materials.
[0033] The follower reciprocating device 4 is fixedly installed on the crushing box 1. It can drive the active crushing gear 6 to slide back and forth on the driven crushing gear 7, thereby increasing the shearing and crushing force for the crushing operation and improving the crushing effect. The follower reciprocating device 4 is installed below the meshing crushing device 2 and includes a reciprocating drive frame 8. The reciprocating drive frame 8 is connected to the meshing crushing device 2 for power transmission and is configured to drive the active crushing gear 6 to slide back and forth.
[0034] The spacing adjustment device 3 is fixedly installed on the crushing box 1. The spacing adjustment device 3 is rotatably connected to the meshing crushing device 2. It is configured to adjust the spacing between the crushing gears. By adjusting the spacing between the driving crushing gear 6 and the driven crushing gear 7, it is convenient to clean the crushing device after the crushing operation is completed.
[0035] The adjustable force application device 5 is fixedly installed on the spacing adjustment device 3 and is configured to adjust the rotational damping of the driven crushing gear 7. By adjusting the rotational damping of the driven crushing gear 7, the meshing force and sliding shear force between the driving crushing gear 6 and the driven crushing gear 7 can be changed, thereby adjusting the degree of crushing of the additive raw materials.
[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the meshing crushing device 2 further includes a crushing motor 9 and a fixed frame 10. The fixed frame 10 is slidably disposed on the side wall of the crushing chamber 1. The crushing motor 9 is fixedly disposed on the fixed frame 10. The gear shaft of the active crushing gear 6 is slidably disposed on the side wall of the crushing chamber 1. The gear shaft of the active crushing gear 6 is rotatably disposed on the fixed frame 10. The crushing motor 9 and the active crushing gear 6 are connected by a power connection. The crushing motor 9 drives the active crushing gear 6 to rotate. At the same time, the fixed frame 10 and the active crushing gear 6 can slide back and forth synchronously on the crushing chamber 1.
[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a sliding block 11 is rotatably fitted on the gear shaft of the driven crushing gear 7. The sliding block 11 is symmetrically arranged about the central plane of the driven crushing gear 7. The sliding block 11 is slidably disposed on the side wall of the crushing chamber 1, so that the driven crushing gear 7 can slide on the crushing chamber 1, which facilitates the adjustment of its position.
[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the follower reciprocating device 4 further includes a drive cylinder 12, a drive bevel gear 13, and a transmission shaft 14. The reciprocating drive frame 8 is slidably disposed on the side wall of the crushing chamber 1. A drive rack 15 is fixedly disposed on the inner side wall of the reciprocating drive frame 8. The drive rack 15 is symmetrically disposed about the central plane of the reciprocating drive frame 8. The drive cylinder 12 is fixedly disposed on the outer side wall of the crushing chamber 1. The extended end of the drive cylinder 12 is fixedly connected to the reciprocating drive frame 8. The drive cylinder 12 can drive the reciprocating drive frame 8 to slide back and forth on the crushing chamber 1 to adjust the position of the reciprocating drive frame 8.
[0039] The driving bevel gear 13 is fixedly mounted on the gear shaft of the driving crushing gear 6. The transmission shaft 14 is rotatably mounted on the bottom wall of the fixed frame 10. One end of the transmission shaft 14 is fixedly mounted with a driven bevel gear 16, which meshes with the driving bevel gear 13. The other end of the transmission shaft 14 is fixedly mounted with a reciprocating gear 17, which meshes with the drive rack 15. The driving bevel gear 13 rotates with the driving crushing gear 6 and transmits power to the reciprocating gear 17. Through the meshing motion of the reciprocating gear 17 and the drive rack 15, the driving crushing gear 6 is driven to slide. When the position of the reciprocating drive frame 8 is adjusted by the drive cylinder 12, the reciprocating gear 17 can mesh with another drive rack 15, thereby driving the driving crushing gear 6 to slide in the opposite direction. By repeating the above actions, the reciprocating sliding of the driving crushing gear 6 can be achieved.
[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the spacing adjustment device 3 includes an adjustment cylinder 18, which is fixedly mounted on the outer side wall of the crushing chamber 1. The extended end of the adjustment cylinder 18 slides through the side wall of the crushing chamber 1. An adjustment frame 19 is fixedly mounted on the extended end of the adjustment cylinder 18. The adjustment frame 19 is rotatably connected to the gear shaft of the driven crushing gear 7. The adjustment cylinder 18 can drive the driven crushing gear 7 to slide on the crushing chamber, thereby adjusting the spacing between the driving crushing gear 6 and the driven crushing gear 7, which facilitates cleaning and maintenance of the equipment after crushing operations.
[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the adjustable force-applying device 5 includes a fixed plate 20 and a force-applying gear 21. The force-applying gear 21 is fixedly mounted on the gear shaft of the driven crushing gear 7. The fixed plate 20 is fixedly mounted on the adjusting frame 19. A fixed rod 22 is fixedly mounted on the fixed plate 20. A force-applying rod 23 is rotatably mounted on the fixed rod 22. A force-applying block 24 is fixedly mounted on one end of the force-applying rod 23. The force-applying block 24 is configured to cooperate with the force-applying gear 21. The force-applying block 24 can be pressed into the tooth groove of the force-applying gear 21. An adjusting spring 25 is fixedly mounted on the other end of the force-applying rod 23. An adjusting bolt 26 is threadedly mounted on the fixed plate 20. An adjusting plate 27 is rotatably mounted on the adjusting bolt 26. The adjusting plate 27 is fixedly connected to the adjusting spring 25.
[0042] Under the elastic force of the adjusting spring 25, the force-applying block 24 on the force-applying rod 23 presses against the force-applying gear 21, which can apply a resistance to the rotation of the driven crushing gear 7. By adjusting the height of the adjusting plate 27, the compression of the adjusting spring 25 can be adjusted, thereby adjusting the rotational resistance. When the rotational force is greater than the rotational resistance, rotation can be performed, and the force-applying block 24 enters another tooth groove to apply continuous force, thereby adding an adjustable interaction meshing force to the meshing of the driving crushing gear 6 and the driven crushing gear 7, so as to adjust the degree of crushing.
[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, a storage box 28 is connected to the bottom of the crushing box 1. The storage box 28 is used to store the crushed additive raw materials. A feeding box 29 is connected to the upper part of the crushing box 1. The feeding box 29 is used to feed the additive raw materials. A feeding shaft 30 is rotatably arranged inside the feeding box 29. A feeding rod 31 is fixedly arranged on the feeding shaft 30. Multiple sets of feeding rods 31 are arranged. A feeding motor 32 is fixedly arranged on the outer wall of the feeding box 29. The feeding motor 32 is poweredly connected to the feeding shaft 30. The feeding motor 32 drives the feeding shaft 30 to rotate. Under the action of multiple sets of feeding rods 31, the feeding speed can be accelerated and the clogging of the feeding box 29 can be avoided.
[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
