[0047] Through the setting of the first connecting component, the second connecting component and the vibrator, the discharge hopper 106 can generate continuous vibration, and cooperate with the tilt setting of the discharge hopper 106 to pour out the material on the discharge hopper 106 to avoid residual material on the discharge hopper 106.

[0048] The screening device includes a receiving box 105, a first connecting member 134, a second connecting member 127, a roller 116, a first pull rope 118, a second pull rope and a collecting box 133; the receiving box 105 is arranged between the crushing box 101 and the discharge hopper 106; the first connecting member 134 connects one end of the receiving box 105 to the second support plate 121; the second connecting member 127 connects the other end of the receiving box 105 to the fourth support plate 108; the roller 116 is arranged at the bottom of the crushing box 101 ; The first pull rope 118 and the second pull rope are wound around the two ends of the roller 116; the collecting box 133 is arranged below one end of the material receiving box 105; a plurality of through holes are provided on the material receiving box 105, and a drop opening 1051 is provided at one end of the material receiving box 105, and the drop opening 1051 is located above the collecting box 133; the first pull rope 118 and the second pull rope are respectively connected to the two ends of the material receiving box 105, and when the roller 116 rotates, the first pull rope 118 and the second pull rope intermittently pull the two ends of the material receiving box 105 to move.

[0049] As the first and second pull ropes 118 and 119 pull the receiving box 105 to move, the box 105 gradually forms inclined surfaces with different inclinations. The material is screened on the receiving box 105, with small particles falling through the through holes onto the discharge device, while large particles remain on the receiving box 105. When one end of the receiving box 105 moves to the drop opening 1051, the large particles fall from the drop opening 1051 into the collection box 133, where they are collected and sent back to the crushing device for secondary crushing.

[0050] The first connecting member 134 is provided with a second supporting rod 137, and the second supporting rod 137 is provided with a first supporting rod 137. The first supporting rod 137 is provided with a first supporting rod 137, and the second supporting rod 137 is provided with a first supporting rod 137.

[0051] A second mounting plate 114 is provided on the fourth support plate 108, a second mounting groove is provided on the second mounting plate 114, a second connecting member 127 is fixedly connected to the second mounting groove by bolts, a second supporting portion is provided on the second connecting member 127, and a second connecting groove corresponding to the second connecting shaft 129 is provided on the second supporting portion; a third reinforcing rod 138 is provided on the second connecting member 127, and the third reinforcing rod 138 is arranged at an angle to improve the structural strength of the second connecting member 127.

[0052] By utilizing the cooperation between the second connecting shaft 129 and the connecting groove, while providing support force for the receiving box 105, the second connecting shaft 129 can rotate in the connecting groove, thereby generating an inclined surface on the receiving box 105, which facilitates the rolling of the material on the receiving box 105 and thus fully screening the material; the first connecting member 134 and the second connecting member 127 are connected to the second support plate 121 and the fourth support plate 108, so that the first connecting member 134 and the second connecting member 127 vibrate together when the discharge hopper 106 vibrates, driving the receiving box 105 to vibrate, thereby improving the screening efficiency of the material by the receiving box 105, and allowing small particles to fall quickly from the receiving box 105; the vibration of the discharge hopper 106 is used to drive the receiving box 105 to vibrate together, without the need to set up other power sources, further improving the energy-saving performance of the crusher.

[0053] The receiving box 105 is provided with a first connecting block 142 and a second connecting block, and the first connecting block 142 and the second connecting block are respectively arranged at the two ends of the receiving box 105, the first connecting block 142 is connected to the third connecting block 143, and the second connecting block is connected to the fourth connecting block, the first pull rope 118 is connected to the third connecting block 143, and the second pull rope is connected to the fourth connecting block, and the two ends of the roller 116 are respectively provided with a first cam 117 and a second cam, the first pull rope 118 is wound around the first cam 117, and the second pull rope is wound around the second cam, and the flanges of the first cam 117 and the second cam are staggered; the first cam 117 and the second cam are respectively provided with annular grooves to facilitate the connection and limiting of the first pull rope 118 and the second pull rope.

[0054] Specifically, a third connecting groove is provided on the first connecting block 142, the third connecting block 143 is in the third connecting groove, a first movable groove is provided on the side wall of the third connecting block 143, a fixed block 144 and a third spring 145 are provided in the first movable groove, one end of the third spring 145 is fixedly connected to the fixed block 144, and the other end is fixedly connected to the inner wall of the first movable groove, a fixed groove 148 corresponding to the fixed block 144 is provided on the inner wall of the third connecting groove, and an inclined surface is provided on the bottom surface of the fixed block 144; a fifth connecting block 146 is provided on the fixed block 144, a second movable groove for moving the fifth connecting block 146 is provided on the side wall of the first movable groove, and a push rod 147 is rotatably connected to the fifth connecting block 146; the connection method of the fourth connecting block and the second connecting block is the same as the connection method of the third connecting block 143 and the first connecting block 142.

[0055] By setting the first connecting block 142, the second connecting block, the third connecting block 143 and the fourth connecting block, the first pull rope 118 and the second pull rope can be conveniently and quickly connected to the material receiving box 105, and the first pull rope 118 and the second pull rope can also be quickly removed from the material receiving box 105; taking the third connecting block 143 and the first connecting block 142 as an example, the third connecting block 143 can be directly inserted into the third connecting groove to complete the connection between the third connecting block 143 and the first connecting block 142; when disassembling the third connecting block 143, the push rod 147 is turned out from the second movable groove, and the push rod 147 is pushed to move. The push rod 147 drives the fixed block 144 to move so that the fixed block 144 is disengaged from the fixed groove 148, and the third connecting block 143 can be directly taken out from the third connecting groove to complete the disassembly of the third connecting block 143.

[0056] The setting of the push rod 147 makes it easier to disassemble the third connecting block 143. At the same time, the push rod 147 is rotated and connected to the fifth connecting block 146 to prevent the push rod 147 from being accidentally touched during normal use, thereby ensuring the connection effect between the third connecting block 143 and the first connecting block 142.

[0057] As roller 116 rotates, first cam 117 and second cam rotate accordingly. Since first pull cord 118 is wound around first cam 117 and second pull cord is wound around second cam, the rotation of first cam 117 and second cam causes the first pull cord 118 and second pull cord to intermittently pull third connecting block 143 and fourth connecting block, thereby moving both ends of material receiving box 105. When first cam 117 rotates to its highest point, first pull cord 118 pulls third connecting block 143, causing one end of material receiving box 105 to rise. When first cam 117 rotates to its lowest point, first pull cord 118 relaxes, and third connecting block 143, activated by first spring 125, returns to its original position, causing one end of material receiving box 105 to descend. Similarly, the cooperation between the second cam and second pull cord causes the other end of material receiving box 105 to intermittently rise and fall.

[0058] A plurality of flaps are provided at the bottom of the crushing box 101, and a third connecting shaft is provided at one end of the flap. A synchronous wheel 149 is provided on the third connecting shaft. The synchronous wheel 149 and the roller 116 form a transmission cooperation through a synchronous belt 120; a protective cover is provided on the side wall of the crushing box 101, and the synchronous wheel 149 and the roller 116 are both in the protective cover, and a second motor for driving the synchronous wheel 149 to rotate is provided on the protective cover; the flap is provided to control the opening and closing of the discharge port at the bottom of the crushing box 101. When the flap is in a horizontal state, the adjacent flaps cooperate with each other to form a plate-like structure to close the discharge port; when the flap is in a vertical state, the discharge port is opened to discharge the material.

[0059] The fourth support plate 108 is provided with a third connecting rod 115, and a fifth support plate 132 is provided at the bottom of the third connecting rod 115. The fifth support plate 132 is provided with a baffle 150. The collecting box 133 is placed on the fifth support plate 132, and the baffle 150 positions the collecting box 133 so that the collecting box 133 is always placed below the blanking port 1051; a protrusion 151 is provided on the side wall of the collecting box 133, and a groove is provided on the baffle 150. When the collecting box 133 is placed on the fifth support plate 132, the protrusion 151 is in the groove, and the collecting box 133 is fixed by the cooperation of the protrusion 151 and the groove to prevent the collecting box 133 from falling off the fifth support plate 132 when the fourth support plate 108 vibrates; when the fourth support plate 108 vibrates, it drives the collecting box 133 to vibrate, thereby shaking the large particles in the collecting box 133 evenly to prevent the large particles from accumulating in one place in the collecting box 133.

[0060] During use, the material first enters the crushing device for preliminary crushing, and then falls into the receiving box 105 on the screening device. The second motor drives the synchronous wheel 149 to rotate, and the synchronous wheel 149 drives the roller 116 to rotate through the synchronous belt 120. When the roller 116 rotates, the two ends of the receiving box 105 are pulled to move by the first pull rope 118 and the second pull rope. At the same time, the synchronous wheel 149 drives the flap to rotate, thereby controlling the opening and closing of the discharge port at the bottom of the crushing box 101; the first pull rope 118 and the second pull rope intermittently pull the two ends of the receiving box 105 to move, so that the receiving box 105 intermittently produces inclined surfaces in different directions, and the material When the material first falls onto the receiving box 105, the receiving box 105 tilts away from the drop-out port 1051, allowing the material to be fully screened on the receiving box 105 and preventing small particles from entering the collection box 133. When the receiving box 105 tilts toward the drop-out port 1051, the flap rotates to close the discharge port, temporarily stopping the material from falling. The material on the receiving box 105 moves toward the drop-out port 1051, and the large particles remaining on the receiving box 105 fall into the collection box 133 for screening. Subsequently, the large particles in the collection box 133 are sent back to the crushing device for secondary crushing until the required particle size is achieved.
