DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0035] Example 1

[0036] An ore grinding and refining processing equipment, such as Figures 1-6As shown, it includes a grinding barrel 1, a feed hopper 2, a support frame 3, an anti-slip bottom block 31, a grinding wheel 4, a grinding cylinder 5, a crushing mechanism 6 and a rotating mechanism 7. The top of the grinding barrel 1 is connected to the feed hopper 2, and the lower part of the grinding barrel 1 is connected to the support frame 3 by welding. Four anti-slip bottom blocks 31 are fixed at intervals on the bottom end of the support frame 3. The lower part of the inner wall of the grinding barrel 1 is fixed with a grinding cylinder 5. A crushing mechanism 6 is provided on the grinding barrel 1, and the crushing mechanism 6 can crush the ore. A rotating mechanism 7 is provided between the crushing mechanism 6 and the grinding barrel 1. Three grinding wheels 4 are provided on the rotating mechanism 7, and the grinding wheel 4 can grind the ore. The rotating mechanism 7 can drive the grinding wheel 4 to rotate, and the grinding wheel 4 is located in the grinding cylinder 5.

[0037] like Figure 3 and Figure 4 As shown, the crushing mechanism 6 includes a servo motor 61, a drive shaft 62 and an impact frame 63. The servo motor 61 is connected to the left side of the upper part of the grinding barrel 1 by bolt connection. The drive shaft 62 is rotatably provided on the upper part of the grinding barrel 1. The left end of the drive shaft 62 is fixedly connected to the output of the servo motor 61. Eight impact frames 63 are fixedly connected to the drive shaft 62 at intervals. When the impact frame 63 rotates, the impact frame 63 can crush the ore.

[0038] like Figure 3 、 Figure 5 and Figure 6 As shown, the rotating mechanism 7 includes a reversing horizontal shaft 71, a driving vertical shaft 72, an H-shaped positioning frame 73, a first buffer spring 74, a second buffer spring 75 and a rubber sleeve 76. A reversing horizontal shaft 71 is rotatably provided on the right side of the middle of the grinding barrel 1. The reversing horizontal shaft 71 and the driving shaft 62 are driven by a synchronous belt assembly. A driving vertical shaft 72 is rotatably provided in the middle of the lower inner side of the grinding barrel 1. The driving vertical shaft 72 and the reversing horizontal shaft 71 are driven by a bevel gear. Three H-shaped positioning frames 73 are slidingly provided on the driving vertical shaft 72 at intervals. The three H-shaped positioning frames 73 are respectively slidably connected to the three grinding wheels 4. Two first buffer springs 74 are connected between the three H-shaped positioning frames 73 and the three grinding wheels 4. A second buffer spring 75 is connected between the three H-shaped positioning frames 73 and the three grinding wheels 4. A rubber sleeve 76 is fixed in the middle of the top of the three grinding wheels 4, and the rubber sleeve 76 is rotatably connected to the driving vertical shaft 72.

[0039] First, the operator places the collection container directly below the grinding barrel 1, and then pours an appropriate amount of ore into the grinding barrel 1 through the feed bucket 2, and starts the servo motor 61. The servo motor 61 drives the drive shaft 62 to rotate forward, and the drive shaft 62 rotates forward to drive the impact frame 63 to rotate forward. The impact frame 63 rotates forward to crush the ore, and then the crushed ore falls and contacts the grinding wheel 4. At the same time, the drive shaft 62 drives the reversing horizontal shaft 71 to rotate forward through the synchronous belt assembly, and the reversing horizontal shaft 71 rotates forward through the bevel gear transmission to drive the driving vertical shaft 72 to rotate forward, and the driving vertical shaft 72 rotates forward through the three H-shaped positioning frames 73. The first buffer spring 74 plays a buffering role, and the three H-shaped positioning frames 73 rotate forward and drive the three grinding wheels 4 to rotate forward respectively, so that the three grinding wheels 4 rotate forward and cooperate with the grinding cylinder 5 to grind the ore. The second buffer spring 75 plays a buffering role, and the grinding wheel 4 has a certain deformation space when rotating forward, thereby ensuring that the ore can be efficiently ground and refined, and then the mineral powder flows into the collection container. After all the ore is ground, the servo motor 61 is turned off, the drive shaft 62 stops driving the impact frame 63 to rotate forward, and the grinding wheel 4 also stops rotating forward, and then the collection container is picked up for subsequent processing of the mineral powder.

[0040] Example 2

[0041] On the basis of Example 1, Figure 7-Figure 9 As shown, it also includes a screening mechanism 8, which includes a positioning cam 82, a limiting base frame 81, a fixed guide rail 83, a vibrating screen plate 84, a positioning side frame 85 and a return spring 86. The right part of the reversing horizontal shaft 71 is fixedly connected to the positioning cam 82, and the upper part of the grinding barrel 1 is slidably provided with a fixed guide rail 83, and a vibrating screen plate 84 is fixedly connected to the fixed guide rail 83. The vibrating screen plate 84 can screen the crushed ore, and the front part of the fixed guide rail 83 is fixedly connected to the positioning side frame 85, and the right part of the positioning side frame 85 is fixedly connected to the limiting base frame 81. The positioning cam 82 can rotate to contact the limiting base frame 81, and four return springs 86 are evenly spaced and connected between the fixed guide rail 83 and the grinding barrel 1.

[0042] like Figure 7 、 Figure 10 and Figure 11 As shown, it also includes a return mechanism 9, which includes a positioning base 91, a reset guide rod 92, a limit spring 93, a return scraper 94, a guide plate 95 and a positioning roller 96. The left and right sides of the drive shaft 62 are fixedly connected to the positioning base 91, and the left and right positioning bases 91 are slidably provided with reset guide rods 92. The left and right reset guide rods 92 are respectively connected to the left and right positioning bases 91 with limit springs 93. A return scraper 94 is fixed between the rear ends of the left and right reset guide rods 92. The return scraper 94 can throw up larger ores and crush them again. The guide plate 95 is fixed to the front side of the upper part of the grinding barrel 1. The guide plate 95 is located above the vibrating screen plate 84. Positioning rollers 96 are rotatably provided on the left and right sides of the return scraper 94.

[0043] When the servo motor 61 is working, the impact frame 63 rotates forward to crush the larger ore, and the ore falls onto the vibrating screen plate 84. The reversing horizontal shaft 71 rotates forward to drive the positioning cam 82 to rotate forward. The positioning cam 82 rotates forward and contacts the limiting base frame 81. The positioning cam 82 rotates forward to drive the limiting base frame 81 to move forward. The limiting base frame 81 moves forward to drive the positioning side frame 85 to move forward. The positioning side frame 85 moves forward to drive the fixed guide rail 83 to move forward. The return spring 86 is compressed, and the fixed guide rail 83 moves forward to drive the vibrating screen plate 84 to move forward. The rear positioning cam 82 continues to rotate forward and disengages from the limiting chassis 81. Due to the action of the reset spring 86, the fixed guide rail 83 drives the vibrating screen plate 84 to move backward and reset, and the limiting chassis 81 also moves backward and reset. This process is repeated, and the vibrating screen plate 84 moves back and forth to screen the ore. After all the ore is ground, the servo motor 61 is turned off, and the positioning cam 82 stops driving the positioning side frame 85 to move forward and backward through the limiting chassis 81, and the vibrating screen plate 84 also stops moving back and forth. In this way, large pieces of ore that have not been crushed can be screened out, ensuring effective processing.

[0044] When the servo motor 61 is working, the drive shaft 62 rotates to drive the left and right positioning bases 91 to rotate forward, and the left and right positioning bases 91 respectively drive the left and right reset guide rods 92 to rotate forward, and the left and right reset guide rods 92 rotate forward to drive the return scraper 94 to rotate forward. Due to the action of the limit spring 93, the reset guide rod 92 always drives the return scraper 94 to contact the inner wall of the grinding barrel 1, so that the return scraper 94 rotates forward and throws the ore screened on the vibrating screen plate 84 through the guide plate 95. The ore is thrown up and contacts the impact frame 63 again to be crushed. After all the ore is ground, the servo motor 61 is turned off, and the drive shaft 62 stops driving the left and right reset guide rods 92 to rotate forward through the left and right positioning bases 91, and the return scraper 94 also stops rotating forward. In this way, larger ores can be thrown up for repeated crushing to ensure sufficient crushing.

[0045] Example 3

[0046] On the basis of Example 1 and Example 2, Figure 12 and Figure 13 As shown, it also includes a material distribution mechanism 10, which includes a spiral plate 101 and a mounting horizontal shaft 102. The lower part of the feed bucket 2 is rotatably provided with a mounting horizontal shaft 102. The mounting horizontal shaft 102 and the drive shaft 62 are driven by a synchronous belt assembly. The left and right sides of the mounting horizontal shaft 102 are fixed with spiral plates 101. The spiral plates 101 can realize uniform feeding of ore, and the spiral directions of the spiral plates 101 on the left and right sides are opposite.

[0047] like Figure 12 and Figure 14As shown, it also includes a dustproof mechanism 11, which includes a mounting base frame 111 and a dustproof cloth cover 112. The mounting base frame 111 is fixedly connected to the middle of the outer bottom of the grinding barrel 1, and the left and right sides of the mounting base frame 111 are fixedly connected to dustproof cloth covers 112. The dustproof cloth cover 112 can prevent dust from being raised when discharging.

[0048] When the servo motor 61 is working, the drive shaft 62 drives the installation horizontal shaft 102 to rotate forward through the synchronous belt assembly. The installation horizontal shaft 102 rotates forward and drives the left and right spiral plates 101 to rotate forward. The left and right spiral plates 101 rotate forward to evenly distribute the ore in the feed bucket 2. In this way, the feed bucket 2 can be prevented from being blocked and affecting subsequent grinding.

[0049] First, the operator places the collection container directly under the dustproof cloth cover 112 on the left and right sides. After the ore grinding is completed, the ore powder falls into the collection container through the dustproof cloth cover 112, thereby ensuring that the environment at the discharge is clean and tidy. In this way, when discharging, dust can be prevented from being raised and affecting the surrounding environment.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.
