[0024] In order to make the above purpose, features and advantages of the utility model can be more obvious and easy to understand, the following specific embodiment of the utility model with the description of the drawings is explained in detail.

[0025] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description herein, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited to the following disclosed specific embodiments.

[0026] Secondly, the "one embodiment" or "embodiments" referred to herein are intended to encompass a particular feature, structure, or characteristic in at least one implementation of the utility model. The "in one embodiment" appearing in different places in the specification does not refer to the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

[0027] Embodiment 1

[0028] With reference to Figures 1-6 For the first embodiment of the utility model, the embodiment provides a feeding mechanism of a small mobile crushing station, the feeding mechanism of the small mobile crushing station comprises a main body assembly 100, including a feeding hopper 101, a feeding chute 102 and a fixed frame 103, the feeding chute 102 is fixed below the feeding hopper 101, and the fixed frame 103 is located below the feeding chute 102.

[0029] The feeding chute 102 has a certain inclination angle, the stone falls into the feeding chute 102 through the feeding hopper 101, the vibration motor starts to operate, and the vibration force generated by the vibration motor is transmitted to the feeding chute 102 through the exciter, under the continuous excitation of the excitation source, the material is repeatedly thrown up and falls down, continuously jumps forward in the feeding chute 102, and thus falls into the crushing device, which is the prior art, and the working principle is not described in detail, and the person skilled in the art can clearly know the working principle.

[0030] The adjusting assembly 200 is arranged below the fixed frame 103 and comprises an adjusting part 201, the adjusting part 201 comprises a fixed column 201a, a moving column 201b, a sliding block 201c, a swing rod 201d, a sleeve 201e and a rotating shaft 201f, the fixed column 201a is arranged below the fixed frame 103, the fixed column 201a is provided with a moving groove 201a-1, the moving column 201b slides in the moving groove 201a-1, the sliding block 201c is fixed on the moving column 201b, the swing rod 201d is provided with a sliding groove 201d-1, the sliding block 201c can slide in the sliding groove 201d-1, the sleeve 201e is fixed on one end of the swing rod 201d, and the rotating shaft 201f is inserted into the sleeve 201e.

[0031] The height of the feed trough 102 can be adjusted by adjusting the adjusting component 201. The fixed column 201a and the moving column 201b provide support. When the rotating shaft 201f drives the sleeve 201e to rotate, it will drive the swing arm 201d to move accordingly. At this time, the slider 201c will move in the slide groove 201d-1. When the slider 201c slides to the end face of the slide groove 201d-1, the swing arm 201d continues to rotate, which will apply a squeezing force to the slider 201c. Since the slider 201c can no longer move, the moving column 201b moves upward along the moving groove 201a-1. At this time, the relative position of the moving column 201b and the fixed column 201a will change, thereby changing the distance between the fixed frame 103 and the ground, so that the height of the feed trough 102 can adapt to the height of different crushers.

[0032] Example 2

[0033] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, the adjustment component 200 also includes a drive component 202, which is located on one side of the rotating shaft 201f. It includes a motor 202a, a worm 202b, and a worm wheel 202c. The motor 202a is located below the rotating shaft 201f, the worm 202b is located on one side of the motor 202a, and the worm wheel 202c is fixed on the rotating shaft 201f. The worm 202b and the worm wheel 202c are engaged.

[0035] The drive unit 202 provides kinetic energy for the height adjustment of the feeding device. The rotating shaft on the motor 202a is connected to the worm gear 202b, so that the rotation of the motor 202a can drive the worm gear 202b to rotate. When the worm gear 202b rotates, it engages with the worm wheel 202c, causing the worm wheel 202c to rotate as well, which in turn drives the rotating shaft 201f to rotate.

[0036] Specifically, the sleeve 201e has a threaded groove 201e-1 inside, and a pin 202d is provided inside the threaded groove 201e-1. The rotating shaft 201f has multiple slots 201f-1, and the pin 202d can engage with the slots 201f-1.

[0037] The pin 202d has threads on its outside. When the pin 202d is fully engaged with the threaded groove 201e-1, the bottom of the pin 202d will enter the slot 201f-1. When the pin 202d is engaged with the slot 201f-1, the rotation of the rotating shaft 201f will drive the sleeve 201e to rotate synchronously. However, when the two are not engaged, the rotation of the rotating shaft 201f will not drive the sleeve 201e to rotate.

[0038] Specifically, the adjusting assembly 200 further comprises a locking member 203 arranged at one side of the fixed column 201a, which comprises an extension block 203a and a locking block 203b.

[0039] The locking member 203 is arranged to ensure that the position of the moving column 201b will not change after being moved to a proper position, thereby ensuring that the feeding will not be displaced during the feeding process and improving the stability.

[0040] The extension block 203a supports the locking block 203b, and a plurality of locking grooves 201b-1 are arranged on the moving column 201b, so that the locking grooves 201b-1 are engaged with the locking block 203b when the moving column 201b is moved to any position. The locking block 203b is inclined at one end, so that the moving column 201b will not affect the movement of the locking block 203b when the moving column 201b is moved upward. When the locking block 203b is engaged with the locking groove 201b-1, the right-angle surface of the locking groove 201b-1 will contact and press the right-angle surface of the locking block 203b, thereby preventing the moving column 201b from moving downward. At the same time, since the worm 202b and the worm wheel 202c have self-locking characteristics, the relative positions of the sliding block 201c, the swing lever 201d and the sleeve 201e will not change after the rotating shaft 201f stops rotating, thereby ensuring the stability of the entire feeding device.

[0041] Specifically, the locking block 203b is fixed with a spring 203c at one side, and the other end of the spring 203c is fixed with the inner wall of the sliding groove 203a-1.

[0042] The spring 203c continuously applies a pushing force to the locking block 203b, so that the locking block 203b can be engaged with the locking groove 201b-1.

[0043] Specifically, the locking block 203b is fixed with a pulling plate 203d at one end.

[0044] The pulling plate 203d is used to unlock the engagement between the locking block 203b and the locking groove 201b-1. When it is necessary to restore the position of the moving column 201b, the pulling plate 203d is pulled to compress the spring 203c, so that the locking block 203b is separated from the locking groove 201b-1. At this time, the motor 202a is reversed to move the moving column 201b downward.

[0045] Embodiment 3

[0046] Reference Figures 1-6 This embodiment is based on the previous two embodiments.

[0047] Specifically, the fixed column 201a is fixed with a support plate 201g, and the support plate 201g is fixed with a support block 201h, and the support block 201h is bearing connected with the rotating shaft 201f.

[0048] The support plate 201g and the support block 201h are used to support the rotating shaft 201f, the rotating shaft 201f is bearing connected with a fixed plate 201i, the motor 202a is bolted with the fixed plate 201i, the fixed plate 201i is fixed with a cross bar 201j at the bottom, and the cross bar 201j is fixed with the support plate 201g on both sides, so as to improve the stability.

[0049] Specifically, the number of fixed columns 201a and mobile columns 201b is four.

[0050] The number of worm gears 202c is two, which can be engaged with the worm 202b.

[0051] Specifically, the number of rotating shafts 201f is two.

[0052] One rotating shaft 201f can control the relative position between two groups of mobile columns 201b and fixed columns 201a at the same time, so as to adjust the height of the whole feeding device to adapt to different inclined ground.

[0053] When it is necessary to adjust the height of four mobile columns 201b at the same time, the four plugs 202d are inserted into the threaded grooves 201e-1 and engaged with the clamping grooves 201f-1, so that the rotation of the rotating shaft 201f can drive the sleeve 201e to rotate, at this time the motor 202a drives the rotating shaft 201f to rotate and drives the four mobile columns 201b to move at the same time, when only the height of a specific mobile column 201b needs to be adjusted, the plug 202d corresponding to the other mobile column 201b is removed, so that the rotation of the rotating shaft 201f will not drive the corresponding sleeve 201e to rotate, and when the height of the specific mobile column 201b is adjusted, the locking blocks 203b on the remaining mobile columns 201b are engaged with the locking grooves 201b-1, and their positions will not change.

[0054] Specifically, the main body assembly 100 further comprises a damping spring 104, and the damping spring 104 is arranged on the fixed frame 103.

[0055] The damping spring 104 supports the weight of the feeding groove 102 and the material on one hand, and absorbs and buffers the impact force generated in the vibration process when the feeding groove 102 vibrates on the other hand, so as to prevent the vibration from being transmitted to the foundation of the equipment and the surrounding environment, which is the prior art, and the working principle of the present scheme will not be described in detail, and the person skilled in the art can clearly know the working principle.

[0056] In use, when the four moving columns 201b need to be adjusted in height, the four plugs 202d are inserted into the threaded grooves 201e-1 and engaged with the clamping grooves 201f-1, the rotating shaft 201f is rotated to drive the sleeve 201e to rotate, the motor 202a is started to rotate, the worm 202b and the worm wheel 202c are driven to rotate, the rotating shaft 201f is driven to rotate, the swing lever 201d is driven to move when the rotating shaft 201f drives the sleeve 201e to rotate, at this time the sliding block 201c will move in the sliding groove 201d-1, when the sliding block 201c slides to the end face of the sliding groove 201d-1, the swing lever 201d continues to rotate, and the sliding block 201c is pressed, so that the moving column 201b moves upward along the moving groove 201a-1, at this time the relative position of the moving column 201b and the fixed column 201a will change, so as to change the distance between the fixed frame 103 and the ground, so that the height of the feeding groove 102 adapts to the height of different crushers, at the same time the worm 202b and the worm wheel 202c are self-locked, and the locking groove 201b-1 is engaged with the locking block 203b, so as to ensure that the height of the moving column 201b does not change during the feeding process, and then the feeding operation can be started.

[0057] When a specific moving column 201b needs to be adjusted in height, the plug 202d corresponding to the other moving columns 201b is removed, the rotating shaft 201f is rotated, and the corresponding sleeve 201e is not rotated, the motor 202a is started to change the height of the specific moving column 201b, and after the specific moving column 201b is moved to the appropriate position, the plug 202d is inserted into the threaded groove 201e-1 again to improve stability, and at the same time when the specific moving column 201b is adjusted, the locking block 203b on the remaining moving columns 201b is engaged with the locking groove 201b-1, and the position does not change.

[0058] When the position of the moving column 201b needs to be restored, the pull plate 203d is pulled to compress the spring 203c, so that the locking block 203b is separated from the locking groove 201b-1, at this time the motor 202a is reversed, and the moving column 201b can be moved downward, if the heights of the moving columns 201b are different, when any one of the moving columns 201b returns to the initial position first, the motor 202a is stopped, the plug 202d corresponding to the moving column 201b is removed, and the motor 202a is continued to be started until all the moving columns 201b are restored.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit the present application, although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
