Example 1

Referring to fig. 1-7, a first embodiment of the present invention provides a roller mechanism that can be separated, screened and reprocessed.

Specifically, the power assembly 100 includes a motor 101, a driving shaft 102 connected to the top of the motor 101, a fixing plate 103 disposed in the middle of the driving shaft 102, a toggle post 104 disposed on the top of the driving shaft 102, and collar members 105 connected to two ends of the fixing plate 103;

the driving assembly 200 comprises a supporting seat 201, a driving turntable 202 movably connected with the top of the supporting seat 201, a plurality of groups of trigger posts 203 arranged at the bottom of the driving turntable 202 in a circular array, a bearing turntable 204 fixedly connected with the top of the driving turntable 202, a first trigger assembly 205 arranged at the outer side of the bearing turntable 204, and two groups of second trigger assemblies 206 arranged at the inner side of the bearing turntable 204 in a circular array; the method comprises the steps of,

a screening assembly 300 mated with the first triggering assembly 205, a comminuting assembly 400 mated with the second triggering assembly 206; and a spiral blanking fan M disposed between the screening assembly 300 and the pulverizing assembly 400.

Further, the collar 105 includes a margin port 105a disposed at one side of the toggle post 104, and a trigger post outlet 105b disposed at the other side of the toggle post 104; the length of the stirring post 104 is the same as the radius of the ferrule 105; the trigger posts 203 are arranged in five groups, and are divided into a first post, a second post, a third post, a fourth post and a fifth post, wherein the angles of the intervals between the groups are the same; the collar member 105 is rotated with its outer side in contact with the two ends of any three sets of the trigger posts 203.

It should be noted that, referring to fig. 4, when the motor 101 is started, the collar member 105, the toggle post 104, and the fixing plate 103 all rotate along with the driving shaft 102. The trigger posts 203 provided on the sides of the collar 105 are designated as first posts and third posts, and a second post is provided intermediate the first and third posts. The toggle post 104 toggles the first post in rotation to enable the driving turntable 202 to rotate for a distance relative to the supporting seat 201, so that the bearing turntable 204 fixedly connected with the driving turntable 202 rotates for a fifth angle, and in the process, the loop piece 105 is in contact with the trigger post 203 to limit, and the rotating distance of the bearing turntable 204 is prevented from changing due to inertia. The trigger post outlet 105b is provided to facilitate removal of the second post from the interior of the collar member 105 during pulling, and the securing plate 103 is provided to stabilize the collar member 105. Precise intermittent rotation is achieved by controlling the load turntable 204 by the power assembly 100.

Further, the first triggering component 205 includes a lifting edge 205a disposed at one end thereof, a horizontal edge 205b in communication with the lifting edge 205a, and a descending edge 205c in communication with the horizontal edge 205 b.

Preferably, the first triggering element 205 is configured as an arc-shaped block with an arc length of two-fifths of the arc length of the carrying turntable 204. When the carrying turntable 204 rotates for the first time, the first adjusting piece 302f slowly rises under the action of the lifting edge 205a and stays in the middle of the horizontal edge 205b for a period of time, the process is reflected in that the switch board 302d rises along a straight line under the action of the first adjusting piece 302f and keeps the highest distance unchanged for a period of time, the second energizing block 302h is separated from the conductive block 307 and the fan 304 is powered off, so that the environment pollution caused by pulverized coal under the action of the fan 304 after the sealed state of the feeding box 301 is released due to the opening of the switch board 302d is avoided, and energy is saved. After the switch plate 302d is lifted, the coal pieces accumulated on the inclined air separation plate 302a fall into the spiral discharging fan M along the length direction of the inclined air separation plate 302a, and finally enter the crushing assembly 400. When the carrying turntable 204 rotates again, the first adjusting piece 302f slowly descends along the descending edge 205c and stays on the surface of the carrying turntable 204, and the feeding box 301 is closed again, so that the fan 304 is electrified to work. When the carrying turntable 204 rotates three times again, the carrying turntable can contact with the tail end of the lifting edge 205a, and the raw materials are subjected to winnowing screening in the longer time, so that the coal blocks start to be accumulated.

Further, the second triggering component 206 is configured as an arc-shaped block, and includes a raised edge 206a disposed at the top thereof, a vertical edge 206b disposed at the side thereof and communicating with the raised edge 206a, and a cushion pad 206c disposed at one side of the vertical edge 206 b; the second trigger assembly 206 has a height that is greater than the first trigger assembly 205.

It should be noted that, the second adjusting member 401 continuously rises under the action of the lifting edge 206a under the rotation of the carrying turntable 204, and forms a certain height difference with the carrying turntable 204 under the action of the vertical edge 206b, when the second adjusting member 401 passes the vertical edge 206b, it falls vertically onto the buffer pad 206c due to its own weight, so as to reduce the impact force and improve the service life of the carrying turntable 204; this process is embodied in that the second adjustment member 401 lifts the grinding head 403 through the extension plate 402 and leaves the time for the coal pieces to enter the spacing collection barrel 404, then the grinding head 403 drops vertically to grind the coal pieces in the spacing collection barrel 404, and the ground coal pieces drop into the carrying container 406 through the screen holes in the grinding screen plate 405 under the vibration of the grinding head 403 striking the grinding screen plate 405. The length of the grinding head 403 is set so that it will not break away from the spacing collection barrel 404 during the lifting process, improving the stability of the device. The two groups of second trigger components 206 can be broken twice in one accumulation and storage process, so that the production efficiency is improved, and the accumulation of coal is avoided.

Further, the screening assembly 300 includes a feeding box 301, a triangular winnowing blanking member 302 disposed in the feeding box 301, a storage box 303 communicated with the triangular winnowing blanking member 302, a fan 304 obliquely disposed on the feeding box 301, a first energizing block 305 connected with the fan 304, a power supply 306 disposed above the storage box 303, and a conductive block 307 connected with the power supply 306.

Further, the triangular winnowing blanking member 302 includes a diagonal winnowing plate 302a, a hollow blanking cavity 302b disposed below the diagonal winnowing plate 302a, an arc blanking cavity 302c disposed below the hollow blanking cavity 302b, a switch plate 302d disposed above the middle of the diagonal winnowing plate 302a, a first linear limiting plate 302e engaged with the switch plate 302d, a first adjusting member 302f connected to one side of the switch plate 302d and engaged with the first triggering assembly 205, an extension frame 302g connected to the switch plate 302d, and a second power-on block 302h connected to the bottom of the extension frame 302 g; a gap is arranged between the first energizing block 305 and the conductive block 307, and the second energizing block 302h is arranged in the gap; the first power-on block 305, the conductive block 307, and the second power-on block 302h are all made of conductive materials; the highest point of the spiral blanking fan M is connected with the bottom end of the inclined winnowing plate 302 a. The inclined air separation plate 302a is inclined, and coal dust enters the hollow blanking cavity 302b through the screening holes under the action of the fan 304, and the coal blocks are accumulated on the inclined air separation plate 302a and are sealed by the switch plate 302 d. The pulverized coal entering the hollow blanking cavity 302b falls into the arc blanking cavity 302c and is finally received in the storage box 303

Further, the crushing assembly 400 includes a second adjusting member 401 matched with the second triggering assembly 206, an extension plate 402 connected to one side of the second adjusting member 401, a crushing head 403 connected to the extension plate 402, a limit collecting barrel 404 disposed below the crushing head 403, a crushing screen plate 405 disposed at the bottom of the limit collecting barrel 404, a carrying storage barrel 406 disposed at the bottom of the crushing screen plate 405, and a second linear limit plate 407 disposed at the top of the limit collecting barrel 404 and engaged with the extension plate 402; the inner diameter of the limit collecting barrel 404 is the same as the diameter of the grinding head 403; both the crushing screen plate 405 and the inclined winnowing plate 302a are provided with screen holes. The side surface of the limit collecting barrel 404 is provided with an inclined groove N connected with the spiral blanking fan plane M.

Preferably, the first linear limiting plate 302e and the second linear limiting plate 407 are arranged to limit the adjusting piece, so that the adjusting piece and the adjusting piece can move along the vertical direction, and the adjusting piece are prevented from being separated, so that normal operation is affected.

Further, the first adjusting member 302f has the same structure as the second adjusting member 401, and the first adjusting member 302f includes a power plate 302f-1 and a roller 302f-2 disposed at the bottom of the power plate 302 f-1. The width of the roller 302f-2 is less than the width of the first trigger assembly 205 and the second trigger assembly 206.

Further, the limiting collector 404 is connected to the lowest point of the spiral blanking fan M. The spiral blanking sector M comprises protection plates M1 arranged on two sides of the spiral blanking sector M.

In use, a worker is only required to start the motor 101 and feed the material through the feed tank 301. Raw materials enter the feeding box 301 and fall on the inclined winnowing plate 302a, the fan 304 screens the raw materials, so that coal dust enters the storage box 303 through the screening holes, coal blocks are accumulated at the switch plate 302d and enter the spiral blanking fan M along with the opening and closing of the switch plate 302 to fall into the crushing assembly 400, and the coal blocks fall into the bearing storage barrel 406 after being crushed by the crushing assembly 400.
