[0026] like Figure 1-5 As shown, the present invention proposes a stone raw material crushing structure, including a crushing box 1, a feeding funnel 2 connected to the top of the crushing box 1, two motors 3 installed on the right side of the crushing box 1, and crushing rollers 4 extending into the crushing box 1 from the output shafts of the two motors 3. A filter plate 6 is provided inside the crushing box 1, which is adapted to the interior of the crushing box 1. A material distribution mechanism 5 is provided inside the crushing box 1, which is located above the two crushing rollers 4. An installation mechanism 7 is provided inside the crushing box 1, which is connected to the filter plate 6 and is used to install and remove the filter plate 6.
[0027] In this invention, the stone to be crushed is fed into the crushing chamber 1 through the feeding funnel 2. By starting the two motors 3, the two motors 3 will drive the two crushing rollers 4 to rotate in opposite directions towards their opposite sides, thereby crushing the stone. The material distribution mechanism 5 ensures that the stone entering the crushing chamber 1 falls stably between the two crushing rollers 4, ensuring that the two crushing rollers 4 completely crush the stone. At the same time, the crushed stone will fall onto the filter plate 6, which can filter the crushed stone. The installation mechanism 7 can quickly install and remove the filter plate 6, which is convenient for maintenance or replacement, ensuring the filtration effect of the filter plate 6.
[0028] like Figure 2As shown, in an optional embodiment, the material distribution mechanism 5 includes a triangular material distribution block 51 and two baffle plates 52. The triangular material distribution block 51 is installed on the front and rear side walls of the inner cavity of the crushing box 1 and is located below the feed funnel 2. The two baffle plates 52 are installed on the front and rear side walls of the inner cavity of the crushing box 1 and are located on the front and back of the triangular material distribution block 51. The bottom of the two baffle plates 52 is inclined to the opposite side, and the bottom of the two baffle plates 52 corresponds to the top of the two crushing rollers 4 respectively.
[0029] When the stone to be crushed falls into the crushing box 1 through the feed funnel 2, the stone will fall to the top of the triangular dividing block 51. Through the diversion of the triangular dividing block 51, the stone will fall from the left and right sides of the triangular dividing block 51 and fall between the opposite sides of the two baffle plates 52. Thus, the stone will fall between the opposite sides of the two crushing rollers 4 through the guidance of the two baffle plates 52, ensuring that the two crushing rollers 4 can fully crush the stone.
[0030] like Figure 3-5 As shown, in an optional embodiment, the mounting mechanism 7 includes a mounting hole 71 on the right side of the crushing chamber 1. A mounting plate 72 is slidably connected inside the mounting hole 71. The left side of the mounting plate 72 is connected to the right side of the filter plate 6. Fixing blocks 73 are installed on both the front and rear side walls of the inner cavity of the crushing chamber 1. Sliding grooves 74 are provided on opposite sides of the two fixing blocks 73. A support plate 75 is slidably connected between the two sliding grooves 74. A connecting block 76 is installed on the top of the support plate 75. The top of the connecting block 76 is connected to the bottom left side of the filter plate 6. A handle 77 is installed on the right side of the mounting plate 72. A fixing component 78 for fixing the mounting plate 72 is provided on the right side of the mounting plate 72. A discharge component 79 is provided inside the crushing chamber 1.
[0031] The left bottom of the filter plate 6 can be supported by two fixing blocks 73, two sliding grooves 74, a support plate 75, and a connecting block 76. The right side of the filter plate 6 can be installed by the mounting plate 72. When the filter plate 6 needs to be disassembled, the mounting plate 72 is first released by the fixing component 78. Then, the mounting plate 72 is pulled to the right by the handle 77. The mounting plate 72 will drive the filter plate 6 to move to the right. The filter plate 6 will drive the connecting block 76 to move to the right. The connecting block 76 will drive the support plate 75 to move to the right inside the two sliding grooves 74. When the support plate 75 is completely discharged from the two sliding grooves 74, the support plate 75, the connecting block 76, and the filter plate 6 can be disassembled, so that the filter plate 6 can be cleaned, repaired, or replaced.
[0032] The inner bottom walls of the two sliding grooves 74 correspond to the inner bottom walls of the mounting holes 71. When installing the filter plate 6, first make the support plate 75 slide in the interior of the two sliding grooves 74, and then push the mounting plate 72 to the left. When the left side of the filter plate 6 contacts the left side wall of the inner cavity of the crushing box 1, the mounting plate 72 is completely slidably connected in the interior of the mounting holes 71. Then, the mounting plate 72 can be fixed by the fixing component 78.
[0033] like Figure 1 , Figure 3 and Figure 5 As shown, in an optional embodiment, the fixing component 78 includes a mounting block 781 and a fixing bolt 782. The mounting block 781 is mounted on the right side of the mounting plate 72, and the left side of the mounting block 781 contacts the right side of the crushing box 1. The fixing bolt 782 is mounted on the right side of the mounting block 781 and extends into the interior of the crushing box 1. The fixing bolt 782 is threadedly connected to the crushing box 1.
[0034] The mounting plate 72 can be fixed by the mounting block 781 and the fixing bolt 782. When the fixing bolt 782 is rotated and disengaged from the crushing box 1, the filter plate 6 can be disassembled. When the fixing bolt 782 is threadedly connected to the crushing box 1, the mounting plate 72 can be fixed, thereby fixing the filter plate 6.
[0035] like Figure 2 As shown, in an optional embodiment, the discharge assembly 79 includes a discharge funnel 791 and a discharge pipe 792. The discharge funnel 791 is installed inside the crushing chamber 1, and the discharge pipe 792 is connected to the inner bottom wall of the discharge funnel 791 and extends to the bottom of the crushing chamber 1.
[0036] The stone material that has been screened by the filter plate 6 will fall directly into the inside of the feeding funnel 791. Under the guidance of the feeding funnel 791, the crushed stone material can be discharged from the discharge pipe 792.
[0037] like Figure 1 As shown, in an optional embodiment, a circulating material box 8 is installed on the left side of the crushing box 1. An auger is installed inside the circulating material box 8. The bottom right side of the circulating material box 8 is connected to the inside of the crushing box 1 and corresponds to the top left side of the filter plate 6. A circulation pipe is connected between the top right side of the circulating material box 8 and the inside of the feed funnel 2.
[0038] Because the left end of the filter plate 6 is tilted downwards, the stones that do not meet the crushing specifications will remain on the top of the filter plate 6 and move to the left under its gravity into the circulating material box 8. By starting the auger, the stones that do not meet the crushing specifications can be lifted upwards and sent into the feed hopper 2 through the circulation pipe, so that the stones that do not meet the crushing specifications can be crushed again.
[0039] like Figure 1 As shown, in an optional embodiment, a base 9 is installed at each of the four bottom corners of the crushing box 1, and a controller is installed on the front of the crushing box 1.
[0040] The crushing chamber 1 can be supported by four bases 9, and the motor 3 and the auger are electrically connected to the controller, which can control the motor 3 and the auger.
[0041] Working principle:
[0042] In operation, this stone crushing structure uses two motors 3 and an auger to feed the stone to be crushed into the crushing chamber 1 through the feed funnel 2. As the stone falls into the crushing chamber 1 through the feed funnel 2, it lands on top of the triangular dividing block 51. The triangular dividing block 51 then diverts the stone, causing it to fall from the left and right sides of the block and into the space between the two baffle plates 52. Guided by the baffle plates 52, the stone then falls between the two crushing rollers 4, ensuring thorough crushing. The crushed stone then falls onto the filter plate 6, which filters the stone. The installation mechanism 7 allows for quick installation and removal of the filter plate 6, facilitating maintenance or replacement and ensuring its filtration efficiency.
[0043] 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.
