The working principle of the invention is as follows: during operation, firstly, the spiral cover is opened, then corn or peanut is poured into the feeding pipe 270 in batches, then the spiral cover is tightly closed, and as the feeding pipe 270 is consistent with the axis of the feeding port 26, corn or peanut directly falls onto one of the guide plates 22 close to the first screen frame 30, and the two guide blocks 271 slide to the feeding port 26 when the corn or peanut splashed conveniently falls down, so that the omission of feeding is prevented, and tiny heavy impurities in the secondarily screened corn or peanut, such as sand stones, fall into the bottom of the screening box 2, and the screening box 2 is obliquely designed, so that the tiny heavy impurities are discharged to the outside of the screening box 2 from the discharge channel 28.
At the same time of feeding, the motor 320 is started by the controller, so that the output end of the motor is rotated clockwise, and as the output end of the motor is fixedly connected with the driving wheel 321, each driven wheel 323 is fixedly connected with one end of one rotating shaft, the driving wheel 321 and the two driven wheels 323 are sleeved by the belt 322, and the driving wheel 321 is smaller than the two driven wheels 323, so that the two rotating shafts keep proper speed to rotate clockwise.
When the rotating shaft rotates clockwise, one end of the connecting rod 330 is fixedly connected with one end of the rotating shaft away from the driven wheel 323, the transverse shaft 332 is fixedly connected with one end of the bottom of the first screen frame 30, and one end of the connecting rod 330 away from the rotating shaft and one end of the transverse shaft 332 are respectively hinged with two ends of the rocker 331, so that the rocker 331 is driven to rotate towards one end away from the driven wheel 323 through the connecting rod 330.
When the connecting rod 330 drives the rocker 331 to rotate towards one end far away from the driven wheel 323, as the four mounting blocks 341 are fixedly connected with the two ends of the first screen frame 30, one of the mounting blocks 341 and one of the limiting blocks 340 are respectively fixedly connected with the two ends of each two leaf springs 342, and then the rotating force of the rocker 331 is converted into the action of sliding to the first slope 23 and then descending under the bending action of the eight leaf springs 342, namely, the first screen frame 30 swings forwards and then downwards.
When the first screen frame 30 swings forwards and downwards, the second screen frame 31 is connected with the rotating assembly 32 in a transmission manner through the other transmission assembly 33, so that the second screen frame 31 swings forwards and downwards synchronously, corn or peanut falling into the first screen frame 30 from the left material guide plate 22 of the first screen frame 30 is vibrated when the first screen frame 30 swings, corn or peanut is conveyed to one end close to the first slope 23 while being thrown, a plurality of first screen holes 300 and a plurality of second screen holes 310 are respectively arranged on the outer walls of the first screen frame 30 and the second screen frame 31 at equal intervals, each first screen hole 300 is larger than one second screen hole 310, so that corn or peanut with larger granularity slides into the first slope 23 from the tail end of the first screen frame 30, corn or peanut with smaller granularity falls into the second slope 31 from the first screen holes 300, and corn or peanut with smaller granularity falls into the second screen holes 31 from the second screen holes 300 under the action of the second screen frame 31, and the corn or peanut with smaller granularity falls into the second screen holes 310 from the second screen holes 24, and the second screen holes 3 are more fine and the impurities such as the fine sand or peanut with smaller granularity falls into the second screen holes 310.
The first slope 23 accepts the peanut and the maize that the granularity of landing is great on the first reel 30 to export it to one of them derivation board 25 from being close to the discharge gate of first slope 23, and second slope 24 accepts the peanut and the maize that the granularity is less of landing on the second reel 31, and export it to another derivation board 25 from being close to the discharge gate of second slope 24, and then conveniently when the screening, the maize or the peanut of different granularity sizes after the synchronous will screening are separately discharged to screening case 2 outside, and the convenience is separately stored, prevents to mix.
At the same time of the swinging vibration of the first screen frame 30, as the inserted link 410 is fixedly connected with one end of the first screen frame 30 far away from the rocking bar 331, thereby driving the inserted link 410 to swing forward and then downward in the arc-shaped groove 21, as the inserted link 410 is spliced with the avoidance groove on the swinging link 411, the swinging link 411 is rotationally connected with the outer wall of the screening box 2, thereby driving the swinging link 411 to rotate towards one end close to the guiding-out plate 25 by taking the hinging point as the circle center, and as one end of the swinging link 411 far away from the hinging point and the top of the pulling block 413 are respectively fixedly connected with two ends of the pulling rope 412, the pulling rope 412 slides towards one end close to the guiding-out plate 25 between the two grooved wheels 415, thereby driving the pulling block 413 to rise and causing the reset spring 414 to be converted into a stretching state from an initial state.
When the pull block 413 rises, because the pull block 413 is fixedly connected with the first baffle 420, thereby drive the first baffle 420 to rise between two of the guide rails, because the first baffle 420 and the second baffle 421 pass through two connecting rods 422 fixed connection, thereby drive the second baffle 421 to follow the synchronous rising of the first baffle 420, make two air outlets 44 open, and when the first baffle 420 rises, this information is detected by the position sensor 423, thereby send it to the controller, thereby start the fan that sets up in two air inlet pipes 43 through the controller, under the effect of negative pressure, the tiny light impurity that lifts up in corn or peanut vibration throwing process discharges to the outside of screening box 2 from two air outlets 44, for example, the dust that lifts up in vibration screening process or corn husks or peanut husks that drop from corn and peanut surfaces, namely, can be synchronous with the dust that lifts up, corn husks or peanut husks discharge to the outside of screening box 2 when rocking vibration screening, simultaneously, when position sensor 423 detects to first baffle 420 descends, reset, the second baffle 421 reset, the fan that resets simultaneously, the two air inlet pipes reset, the fan that need not to stop to be more than the fan, the fan is closed by two air inlet pipes, the effect of reducing the cost of the fan is continued to be kept on in order to reduce the time, the fan is not to open, the fan is required to be closed by two air inlet pipes, and the fan is opened.
