As shown in figure 1, a base 1 is a basic component of the screening machine, a hopper 2 is arranged above the left end of the base, as shown in figure 2, the hopper is in a conical structure with a large upper part and a small lower part, a protrusion 21 is fixed on the inner wall of the upper side of the hopper, a dredging plate 22 is arranged on the inner side of the hopper, and an ear plate 23 connected with the protrusion in a hinged mode is arranged on the upper side of the dredging plate. A vibration exciter 25 is fixed on the side wall of the hopper, and a vibration rod 24 is arranged on the vibration exciter and is in contact with the dredging plate. When the vibration exciter works, the vibration rod can be driven to vibrate, and then the dredging plate is driven to vibrate, so that the blockage caused by accumulation of peanut seeds in the hopper is avoided. The vibration exciter, the vibration rod, the dredging plate and the protrusion form a dredging mechanism.
The small end of the hopper is provided with a through hole, a material discharging pipe 3 is arranged below the through hole, and the material discharging pipe is fixed at the bottom of the hopper. The outer wall of the material discharging pipe is fixed with a fixed ring 31, the fixed ring is fixedly provided with a material discharging motor 32, a rotating shaft 33 fixed at the output end of the material discharging motor is rotatably connected with the material discharging pipe, a spherical material discharging device 34 arranged at the inner side of the material discharging pipe is fixed on the rotating shaft, the outer wall of the material discharging device is provided with a peanut seed groove 35, and a protection pad 12 is arranged in the peanut seed groove. A funnel 36 is arranged on the inner side of the material discharge pipe and positioned above the material discharge device, the large end of the funnel is communicated with the through hole 26 at the small end of the hopper, and the small end of the funnel is positioned right above the material discharge device. Peanut kernels in the hopper pass through the through holes and enter the hopper, and when the peanut kernel groove faces right above, the peanut kernels in the hopper fall into the peanut kernel groove. And then the material spitting motor drives the material spitting device to rotate 180 degrees, and the peanut seeds fall off from the material spitting device to realize the material spitting operation. And only one peanut kernel is removed from the hopper every time the material is spitted, and the size of the peanut kernel groove is matched with that of the peanut kernels. The material spitting motor, the rotating shaft, the material spitting device, the fixing ring and the funnel form a material spitting assembly.
And a screening pipe 4 which is obliquely arranged is arranged below the material discharging pipe, and the screening pipe and the material discharging pipe are in round corner transition. An acute included angle is formed between the screening pipe and the horizontal plane, as shown in fig. 3, a first rail 41 is arranged above the screening pipe, the first rail is fixedly connected with the screening pipe, a first nut 42 is slidably mounted on the first rail, the first nut is matched with a first lead screw 421, the first lead screw is rotatably mounted between a pair of first supporting seats 422 fixed on the first rail, and the first lead screw is driven by a first translation motor 423 to rotate. Grooves 424 are respectively formed in the top and the bottom of the first screw, the grooves are arranged in the front and the back of the screening pipe in the length direction, an installation plate 44 is fixed in the groove in the bottom, an electric telescopic rod 43 is fixed on the installation plate, a pressing block 431 is arranged on the electric telescopic rod, and a pressure sensor is arranged at the bottom of the pressing block. The electric telescopic rod drives the pressing block to be close to the peanut seeds, and after the pressing block is contacted with the peanut seeds, the pressure sensor can sense the pressure between the pressing block and the peanut seeds. If the peanut kernel does not decay, after the pressing block is in contact with a plurality of points on the outer wall of the peanut kernel, the pressure sensed by the pressure sensor is about the value N (or between N1 and N2, and the difference between N2 and N1 is small), wherein N is a certain value larger than 0. If the pressing block contacts with a rotten part on the peanut kernel, the pressure value f sensed by the pressure sensor is smaller than N, and the difference value between f and N is larger. When the electric telescopic rod moves for the same distance, the pressing block is not contacted with the peanut seeds when the pressure sensed by the pressure sensor is zero because the shape of the peanut seeds is not a full circle. The pressure sensed by the pressure sensor is used for judging whether the peanut kernels are rotten or not.
Because the screening pipe is an inclined pipe, the peanut seeds can roll downwards under the action of self gravity. In order to stop the peanut kernel after rolling and facilitate multipoint sampling measurement on the outer wall of the peanut kernel, a fixing rod 45 is fixed in the groove at the upper part, as shown in fig. 6 and 13, a blocking rod 451 is slidably mounted in an inner cavity of the fixing rod, a resisting spring 452 is arranged between the blocking rod and the inner cavity wall of the fixing rod, and most of the blocking rod extends out of the fixing rod under the action of the resisting spring. After the peanut seeds are contacted with the stop lever, the stop lever prevents the peanut seeds from continuously rolling downwards. When the stop lever moves downwards, the peanut kernels move downwards while contacting the stop lever and rotate. The first translation motor acts once, the first nut moves on the first rail once, the peanut seeds rotate once, the electric telescopic rod acts once, the pressure sensor on the pressing block senses the pressure value between the pressing block and the peanut seeds once, and the measured value is transmitted to the controller. After the first translation motor acts for multiple times, the peanut seeds rotate for at least one circle, so that the outer walls of the peanut seeds can be sampled and detected. The lower parts of the electric telescopic rod and the fixed rod penetrate through the first rail and then are arranged on the inner side of the screening pipe, and in order to avoid the electric telescopic rod and the fixed rod, avoiding grooves 46 are respectively formed in the first rail and the screening pipe. In order to drive the stop lever to retract into the inner cavity of the fixing lever, an actuating lever 453 is vertically fixed on the stop lever, one end of the actuating lever is fixedly connected with the stop lever, and a rotating wheel 454 is rotatably mounted at the other end of the actuating lever.

Electric telescopic handle, dead lever and pin all are located the cross section of screening pipe, and perpendicular to screening pipe. After the inclined plane contact on runner and the drive block, along with the continuation removal of first screw, the runner rotates along the inclined plane, and the pin removes relative dead lever, and after the pin withdrawed to one section in the dead lever inner chamber, the effect of blocking of pin to peanut seed grain disappeared, and the peanut seed grain can cross the pin and roll downwards. The fixed rod, the stop lever, the stop spring, the actuating rod and the rotating wheel form a stop mechanism.
As shown in fig. 4, a material distributing pipe 49 is connected to the lower end of the sieving pipe, and the material distributing pipe is communicated with the sieving pipe and forms an acute included angle with the sieving pipe. The material distributing mechanism is arranged at the joint of the material distributing pipe and the screening pipe and mainly comprises a material distributing motor 48 fixed on the screening pipe, a material distributing shaft 481 fixed at the output end of the material distributing motor and a screening plate 482 fixed on the material distributing shaft, wherein the screening plate is a flat plate. When the peanut kernel is intact, the screening board and the screening pipe parallel arrangement and the screening board plug up the branch material pipe, and the peanut kernel rolls from top to bottom along the screening pipe. When peanut seed grain has rotten place, dial material motor drive and dial the material axle and rotate for screening board anticlockwise rotation certain angle, the screening pipe is plugged up to the screening board this moment. Rotten peanut kernel rolls to in the branch material pipe along screening board to the removal of rotten peanut kernel is realized. A collecting tank 13 is arranged below the lower end of the material separating pipe to collect rotten peanut seeds. The material stirring mechanism, the first screw, the first lead screw, the first translation motor, the electric telescopic rod, the pressing block and the blocking mechanism form a screening assembly.
