[0003] However, in existing technologies, some feeding devices lack pre-screening functions for ore particle size. Large pieces of ore may directly enter the crusher, exceeding the equipment's processing capacity, leading to an increased risk of crushing chamber blockage, intensified equipment vibration, and accelerated damage to components. Therefore, we provide a feeding adjustment device for a mining crusher. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a feeding adjustment device for a mining crusher includes a crushing box 11. A ramp 12 is provided at the top of the crushing box 11, and two slide rails 13 are provided at the top of the ramp 12. A screening box 14 is installed at the top of the ramp 12, and pulleys 16 are provided at the four corners of the bottom of the screening box 14. A discharge chute 15 is provided at one end of the screening box 14, and a telescopic cylinder 17 is provided at the end of the screening box 14 away from the discharge chute 15. The pulleys 16 slide within the slide rails 13. A support platform 31 is fixedly connected to the top of the screening box 14 near the ramp 12, and the top of the support platform 31 is fixedly installed with… A telescopic cylinder 17 is provided, the output end of which is fixedly connected to one side of the screening box 14. A screening plate 18 is installed in a slot opened on the side of the crushing box 11 near the slope 12. Two mounting blocks 19 are provided on both sides of the bottom of the screening plate 18. A fixing shell 110 is provided at the bottom of each of the four mounting blocks 19. The screening plate 18 is mated in the slot opened on the top of the crushing box 11. Two mounting blocks 19 are fixedly connected to both sides of the bottom of the screening plate 18. The bottom of the mounting blocks 19 is mated in the fixing shell 110 and slidably connected to the inner wall of the fixing shell 110. Each of the four fixing shells 110 is provided with a... A spring 111 is provided on one side of the crushing box 11, and a mounting shell 112 is provided on one side of the crushing box 11. The top of the spring 111 contacts the bottom of the mounting block 19, and the bottom of the spring 111 is fixedly connected to the bottom side of the inner wall of the fixed shell 110. The outer side of the fixed shell 110 is fixedly connected to the inner wall of the slot opened in the crushing box 11. The mounting shell 112 is fixedly connected to one side of the crushing box 11, and a motor 113 is provided on one side of the mounting shell 112. Gear 114 and gear 215 are provided inside the mounting shell 112. A mounting plate is fixedly connected to one side of the mounting shell 112, and the top of the mounting plate is fixedly installed on the outside of the motor 113. The output end of motor 113 is fixedly connected to one side of gear 114. The teeth of gear 114 mesh with the tooth grooves of gear 2 115. Both gear 114 and gear 2 115 are provided with crushing paddles 116 on the side away from motor 113. Both gear 114 and gear 2 115 are fixedly connected with crushing paddles 116 on the side away from motor 113. The ends of the two crushing paddles 116 away from motor 113 are rotatably connected to the side of the inner wall of crushing box 11 away from motor 113. Both sides of the inner wall of crushing box 11 are provided with toothed blocks 117. The bottom of crushing box 11 is provided with a collecting mechanism 2.

[0024] In this embodiment, when the device is used to crush ore, a batch of ore is first placed into the screening box 14. By activating the telescopic cylinder 17, the screening box 14 can be pushed and pulled back and forth on the slope 12. The pulley 16 will slide in the slide rail 13, which can ensure the accuracy of the screening box 14 when moving on the slope 12. As a result, some ore fragments stored in the screening box 14 will be shaken, and some ore fragments smaller than the opening of the discharge chute 15 will be thrown out of the discharge chute 15 onto the screen plate 18. When the screen plate 18 is impacted from above, the mounting block 19 at its bottom will be recessed into the fixed shell 110 and squeeze the spring 111. The spring 111 can provide cushioning against the impact force. The buffering effect reduces damage to the screen plate 18 when the ore falls. Some ore fragments that can pass through the aperture of the screen plate 18 will fall onto the crushing paddle 116. The toothed blocks 117 provided on both sides of the inner wall of the crushing box 11 can prevent ore fragments from leaking from both sides of the two crushing paddles 116, ensuring that all ore is crushed. Therefore, the motor 113 is started to drive the gear 114 and gear 215 to rotate, and then the two crushing paddles 116 will rotate synchronously to crush the screened ore fragments, avoiding the risk of large pieces of ore directly entering the crusher and causing blockage of the crushing chamber. The screened material will fall from the slot opened at the bottom of the crushing box 11 and be collected in the collection box 21.

[0025] like Figures 1-5 As shown, the collection mechanism 2 includes a collection box 21. Slide grooves 22 are provided on both sides of the inner wall of the collection box 21. A collection container 23 is connected inside the collection box 21. Slide blocks 24 are fixedly connected to both sides of the collection container 23. The outside of the slide blocks 24 slides in the slide grooves 22.

[0026] In this embodiment, the crushed ore can be collected and processed uniformly through the collection box 23. The staff can take the ore material collected in the collection box 23 out of the collection box 21 through the slider 24 and the chute 22.

[0027] This utility model provides a feeding adjustment device for a mining crusher, the specific working principle of which is as follows:

[0028] When the device is needed to crush ore, the ore to be processed is first placed in batches into the screening box 14. By activating the telescopic cylinder 17, the screening box 14 is pushed to reciprocate along the inclined track 12, so that the ore fragments in the box are initially screened during the shaking process. At this time, ore fragments with a particle size smaller than the opening size of the discharge chute 15 will be thrown onto the screen plate 18. When the screen plate 18 is subjected to the impact of the ore from above, the mounting block 19 installed at the bottom of the screen plate 18 will be recessed into the fixed shell 110, squeezing the spring sheet 111 structure. The spring sheet 111 buffers the impact force through elastic deformation, effectively reducing the damage caused by the direct impact of the ore on the screen plate 18. During this process, small ore fragments that meet the aperture requirements of the screen plate 18 will pass through the screen holes and fall directly to the bottom. To prevent ore fragments from leaking through the gaps between the two crushing paddles 116 and to ensure that all material enters the crushing area, toothed blocks 117 are specially designed on both sides of the inner wall of the crushing box 11. These toothed blocks 117 restrict the ore's lateral movement through their interlocking action, forcing the material to always remain within the working range of the crushing paddles 116. Subsequently, the starting motor 113 drives gear one 114 and gear two 115 to rotate synchronously, causing the two crushing paddles 116 to rotate synchronously, thus efficiently crushing the screened ore fragments. This pre-screening mechanism can significantly reduce the risk of large pieces of ore directly entering the crusher, thereby avoiding the problem of clogging the crushing chamber. Finally, the crushed material falls into the collection box 21 through the pre-set slot at the bottom of the crushing box 11, completing the entire crushing process.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
