The dredging mechanism 10; wherein the bulk material mechanism 8 comprises a slide plate 81, an L plate 82, an eccentric wheel 83, a rotating drum 84, a crushing rod 85, a spiral groove 86, an inclined groove 87, a push block 88, a guide rod 89, a push rod 810, a swing rod 811, a hollow rod 812, a baffle 813 and a connecting rod 814; the slide plate 81 is slidably connected to the inner wall of the hopper 2, the outer wall of the slide plate 81 is fixedly mounted with the L plate 82, the outer wall of the rotating shaft 6 is fixedly mounted with the eccentric wheel 83, the outer wall of the eccentric wheel 83 is attached to the outer wall of the L plate 82, and the rotation of the rotating shaft 6 will drive the eccentric wheel 83 to reciprocately squeeze the L plate 82, so that the L plate 82 reciprocates to push and pull the slide plate 81, so that the slide plate 81 reciprocates on the inner wall of the hopper 2, the inner wall of the slide plate 81 is rotatably connected to a rotating drum 84, and a crushing rod 85 is fixedly installed on the outer wall of the rotating drum 84. The coating raw materials inside the hopper 2 can be broken up by the reciprocating rotation of the rotating drum 84 and the crushing rod 85, so as to reduce the particle size of the coating raw materials for grinding the coating raw materials. A spiral groove 86 is provided on the rotating drum 84, and an inclined groove 87 is provided on the top of the machine body 1. A push block 88 is slidably connected to the outer wall of the L plate 82, and a guide rod 89 is fixedly installed on the bottom of the push block 88. The end of the guide rod 89 away from the push block 88 is attached to the inner wall of the inclined groove 87. The slide plate 81 is rotatably connected to the inner wall of the hopper 2. When the push block 88 moves back and forth, it cooperates with the L plate 82 to drive the push block 88 to move back and forth synchronously. When the push block 88 moves back and forth, it will drive the guide rod 89 to move back and forth in contact with the inner wall of the inclined groove 87. At this time, under the guiding action of the inclined groove 87, the guide rod 89 will drive the push block 88 to slide back and forth on the outer wall of the L plate 82. A push rod 810 is fixedly installed on the side wall of the push block 88. The outer wall of the push rod 810 is in contact with the inner wall of the spiral groove 86. When the push block 88 slides back and forth, it will drive the push rod 810 to move back and forth in contact with the inner wall of the spiral groove 86. At this time, the push rod 810 will squeeze the spiral groove 86 back and forth, causing the rotating drum 84 to rotate back and forth on the inner wall of the slide plate 81.

[0031] During the rotation of the eccentric wheel 83, the L plate 82 will be repeatedly squeezed, so that the L plate 82 drives the slide plate 81 to slide back and forth on the inner wall of the hopper 2, and then the rotating drum 84 can be reciprocated and rotated back and forth. The crushing rod 85 on the outer wall of the rotating drum 84 can be used to crush the paint raw materials inside the hopper 2 to reduce the particle size of the paint raw materials so that the paint raw materials can be ground.

[0032] One end of the swing arm 811 is rotatably connected to the inner wall of the hopper 2, and the other end of the swing arm 811 passes through the hopper 2 and is fixedly installed with a hollow rod 812. The swing arm 811 is rotatably connected to the penetration point of the hopper 2, and a baffle 813 is fixedly installed on the outer wall of the swing arm 811. The baffle 813 is located inside the hopper 2. The baffle 813 is driven to swing back and forth by the swing arm 811 to control the opening and closing of the feed pipe 3, so that the paint raw materials inside the hopper 2 fall into the grinding tank 4 for grinding in a quantitative manner.

[0033] A connecting rod 814 is fixedly installed at the bottom of the slide plate 81, and the outer wall of the connecting rod 814 is attached to the inner wall of the hollow rod 812. When the slide plate 81 moves back and forth on the inner wall of the hopper 2, it will drive the connecting rod 814 to move back and forth on the inner wall of the hollow rod 812. At the same time, the connecting rod 814 will push and pull the hollow rod 812 back and forth, so that the hollow rod 812 drives the rocker arm 811 to reciprocate on the inner wall of the hopper 2. The reciprocating rotation of the rocker arm 811 can drive the baffle 813 to swing back and forth up and down inside the hopper 2.

[0034] When this embodiment is working: first, pour the coating raw materials into the interior of the hopper 2, so that the raw materials fall into the interior of the grinding tank 4 through the hopper 2, and at the same time, start the motor 5 to drive the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it will drive the grinding roller 7 to rotate synchronously. The coating raw materials can be ground by the rotation of the grinding roller 7 in coordination with the grinding tank 4. At the same time, during the rotation of the rotating shaft 6, the eccentric wheel 83 will be driven to reciprocately squeeze the L plate 82, so that the L plate 82 pushes and pulls the slide plate 81 reciprocatingly, so that the slide plate 81 slides back and forth on the inner wall of the hopper 2. When the slide plate 81 slides back and forth, it will drive the rotating drum 84 to move back and forth synchronously. At this time, the multiple groups of crushing rods 85 on the outer wall of the rotating drum 84 will move back and forth inside the hopper 2. At the same time, the slide plate 81 2 reciprocates, and the L plate 82 can drive the push block 88 to reciprocate synchronously. The push block 88 reciprocates and drives the guide rod 89 to fit the inner wall of the inclined groove 87 and reciprocate. At this time, under the guidance of the inclined groove 87, the guide rod 89 drives the push block 88 to slide back and forth on the outer wall of the L plate 82. The push block 88 slides back and forth and drives the push rod 810 to fit the inner wall of the spiral groove 86 and reciprocate. At this time, the push rod 810 reciprocates and squeezes the spiral groove 86, so that the rotating drum 84 reciprocates on the inner wall of the slide plate 81. The reciprocating rotation of the rotating drum 84 and the crushing rod 85 can break the paint raw materials inside the hopper 2, thereby reducing the particle size of the paint raw materials, so that the paint raw materials can be crushed. Grinding, at the same time, through the reciprocating movement of the rotating drum 84, the crushing rod 85 can fully crush the paint raw materials on the inner wall of the hopper 2, thereby further improving the crushing effect of the paint raw materials, avoiding excessive differences in the particle sizes of the paint raw materials, and facilitating the grinding of the paint raw materials. While the slide plate 81 reciprocates on the inner wall of the hopper 2, it will drive the connecting rod 814 to reciprocate on the inner wall of the hollow rod 812. At the same time, the connecting rod 814 will reciprocate and push the hollow rod 812, so that the hollow rod 812 drives the swing rod 811 to reciprocate on the inner wall of the hopper 2. The reciprocating rotation of the swing rod 811 can drive the baffle 813 to swing back and forth up and down inside the hopper 2. When the baffle 813 swings to a horizontal state, the baffle 8 13 will block the hopper 2, so that the paint raw materials inside the hopper 2 cannot fall down into the grinding tank 4 for grinding. When the baffle 813 gradually swings to an inclined state, the paint raw materials inside the hopper 2 will fall into the grinding tank 4 from the gap between the baffle 813 and the hopper 2, so that the paint raw materials can enter the grinding tank 4 for grinding. The reciprocating swing of the baffle 813 can control the opening and closing of the hopper 2, so that the paint raw materials inside the hopper 2 can fall into the grinding tank 4 for grinding in a quantitative manner, thereby avoiding the accumulation of paint raw materials inside the grinding tank 4, so that the grinding roller 7 can fully grind the paint raw materials, which is beneficial to improving the grinding effect of the paint raw materials.

The knocking of the rubber ball 108 on the bottom of the sieve plate 92 can vibrate the raw material powder inside the sieve plate 92, thereby preventing the raw material powder from getting stuck in the sieve holes of the sieve plate 92, and thus the sieve plate 92 can be unblocked.

[0042] When this embodiment is working: the slide plate 81 slides back and forth on the inner wall of the hopper 2 and cooperates with the L plate 82 to drive the rack 914 to reciprocate synchronously. The reciprocating movement of the rack 914 can drive the transmission gear 912 meshing with it to reciprocate on the outer wall of the fixed shaft 911. During the rotation of the transmission gear 912, the slide bar 913 will be driven to reciprocate on the inner wall of the through groove 910. At the same time, the slide bar 913 will push and pull the L rod 99 back and forth, so that the L rod 99 swings back and forth and drives the loading barrel 91 to reciprocate on the inner wall of the machine body 1. The reciprocating rotation of the loading barrel 91 will drive the sieve plate 92 to swing back and forth. When the grinding roller 7 finishes grinding the coating raw materials, the raw material powder will fall into the inside of the sieve plate 92. At this time, the reciprocating swing of the sieve plate 92 can screen the raw material powder inside it, and qualified raw material powder will be sieved along the sieve plate The reciprocating swing of 92 discharges the sieve plate 92 and discharges the body 1 through the discharge pipe 3. The unqualified raw material powder will slide into the interior of the loading barrel 91 with the reciprocating swing of the sieve plate 92. At the same time, the rotating shaft 6 can cooperate with the transmission belt 98 to drive the transmission rod 96 to rotate synchronously on the inner wall of the body 1 during the rotation. While the transmission rod 96 rotates, it can cooperate with the large bevel gear 97 and the small bevel gear 95 to drive the auger shaft 94 to rotate on the inner wall of the loading barrel 91. The rotation of the auger shaft 94 can lift the unqualified raw material powder inside the loading barrel 91 upward, so that the unqualified raw material powder can move upward to the discharge pipe 93 and be discharged into the grinding tank 4 again through the discharge pipe 93, so that the unqualified raw material powder can be ground by the grinding roller 7 again, thereby further improving the grinding effect of the coating raw materials, which is beneficial to the subsequent production of the coating.

[0043] When the transmission rod 96 rotates, the driving belt 103 can drive the rotating rod 101 to rotate synchronously on the inner wall of the machine body 1. When the rotating rod 101 rotates, the cam 102 can be driven to push and pull the connecting rod 106 back and forth, so that the connecting rod 106 pushes and pulls the ejector rod 105 back and forth, so that the ejector rod 105 drives the slider 104 to slide back and forth on the inner wall of the machine body 1. The up and down reciprocating sliding of the slider 104 can drive the ejector rod 105 to move back and forth inside the discharge tube 3. The up and down reciprocating movement of the ejector rod 105 can squeeze the raw material powder inside the discharge tube 3 downward, so that the lower The material pipe 3 is unblocked to prevent the raw material powder from being blocked inside the material pipe 3, so that the material pipe 3 can discharge materials stably. At the same time, as the rotating rod 101 rotates, the rubber rod 107 can drive the rubber ball 108 to repeatedly knock on the bottom of the sieve plate 92. The rubber ball 108 knocks on the bottom of the sieve plate 92 to vibrate the raw material powder inside the sieve plate 92, thereby preventing the raw material powder from getting stuck in the sieve holes of the sieve plate 92. The sieve plate 92 can be unblocked to prevent the raw material powder from blocking the sieve plate 92, so that the sieve plate 92 can stably screen the raw material powder.

[0044] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
