Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal devices, in particular to a rapeseed harvesting and impurity removal device. Background Art

[0002] Rapeseed, also known as Brassica rapa, is the seed of the cruciferous crop rapeseed. Rapeseed has long pods, many pods, and full grains. Its oil content varies slightly depending on the type of rapeseed. It is one of China's major oil crops and nectar crops. Its seeds are one of the main varieties of raw materials for making soaked oils. When rapeseed is harvested, its stems and leaves are dry. When harvesting rapeseed, the stems and leaves will also be mixed with it. The stems and leaves mixed with the rapeseed will affect the oil production effect of the rapeseed, so the stems and leaves need to be screened and removed. In order to better remove the stems and leaves in rapeseed, a rapeseed harvesting and impurity removal device is proposed.

[0003] For example, a rapeseed harvesting and impurity removal device disclosed in the authorization announcement number CN209736057U includes a slag removal box and a screw feeder, the top end of the screw feeder is fixed to the top opening of the slag removal box, a sieving mechanism is installed inside the slag removal box, and the sieving mechanism consists of a sieve plate and a base installed below the sieve plate, the sieve plate is connected to the base by a compression spring, the sieve plate includes a first frame, a sieving net is laid inside the first frame, a movable groove is provided on the first frame, and the base includes a second frame;

[0004] Although the impurity screening mechanism is divided into a screen plate and a base, a shifting block is installed on the base through a rotating rod. The shifting block is located below the first frame and has a fan-shaped structure. As the rotating rod rotates, the arc surface of the shifting block constantly contacts and leaves the first frame, thereby realizing the up and down swinging of the screen plate. The swinging amplitude matches the length of the shifting block, so that the rapeseed can be greatly screened for impurities removal;

[0005] However, the problem that the existing impurity removal device is not conducive to convenient circular rotation and reciprocating swing screening of rapeseed impurities during use is not solved, and is not conducive to uniformly blowing away the fine stems and leaves in the rapeseed by reciprocating swing, which affects the effect of rapeseed impurity removal. Utility Model Content

[0006] The purpose of the utility model is to provide a rapeseed harvesting and impurity removal device to solve the problem in the above background technology that the impurity removal device is not convenient for convenient circular rotation and reciprocating swing to screen the rapeseed and remove impurities, is not conducive to the reciprocating swing and uniform blowing and removal of fine stems and leaves in the rapeseed, and affects the effect of rapeseed impurity removal.

[0007] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a rapeseed harvesting and impurity removal device, comprising an integrated box and a screening box, a screening box is installed at the top of the integrated box, two groups of air inlets are installed on the outer wall of one side of the integrated box, and a collecting box is installed on the outer wall of the other side of the integrated box, a screening drum is movably installed inside the screening box, and multiple groups of material guide bars with equal spacing are installed on the inner wall of the screening drum, a gear ring is installed on the outer wall of the screening drum, a driving motor is installed on the outer wall of the screening box, a driving shaft is installed on the output end of the driving motor, a transmission gear is set on the surface of the driving shaft, and the transmission gear and the gear ring are meshed with each other, a material guide slope is installed inside the integrated box, a screening frame is provided inside the integrated box below the material guide slope, and rails are symmetrically installed on the inner wall of the integrated box below the material guide slope, and two groups of integrated plates are installed on the inner wall of the integrated box on the air inlet side.

[0008] Preferably, a reciprocating motor is installed on one side of the integrated board, and a reciprocating gear is installed on the output end of the reciprocating motor.

[0009] Preferably, racks are symmetrically installed on the other side of the integrated board, and the racks are slidably connected to the integrated board, and the racks are meshed with the reciprocating gear.

[0010] Preferably, support blocks are installed on the side walls of the racks, and fans are installed on the side walls of the support blocks.

[0011] Preferably, two sets of movable wheels are symmetrically and movably mounted on the side walls of the screening frame, and the screening frame is slidably connected to the track through the movable wheels.

[0012] Preferably, a servo motor is installed on the inner wall of the integrated box on one side of the screening frame, an articulated shaft is installed on the output end of the servo motor, and a rotating disk is mounted on the surface of the articulated shaft.

[0013] Preferably, a long connecting arm is movably installed at an eccentric position on the top end of the rotating disk, and a short connecting arm is installed at one end of the long connecting arm away from the rotating disk.

[0014] Preferably, a pin is installed at one end of the short connecting arm close to the long connecting arm, and the short connecting arm is movably connected to the long connecting arm through the pin, and the short connecting arm is movably connected to the screening frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the impurity removal device not only realizes convenient circular rotation and reciprocating swing screening of rapeseed, facilitates the reciprocating swing and uniform blowing and removal of fine stems and leaves in the rapeseed, but also improves the effect of rapeseed impurity removal;

[0016] The driving motor drives the transmission gear to rotate through the driving shaft, and the transmission gear drives the screening drum to rotate through the gear ring. The rapeseeds and thin stems and leaves that are smaller than the diameter of the holes on the surface of the screening drum will fall through the holes, and the stems and leaves that are larger than the diameter of the holes will be discharged from the inside of the screening drum under the guiding action of the guide bar. The fan is turned on to blow the falling rapeseeds and thin stems and leaves. The weight of the rapeseed is greater than the wind force of the fan, so the wind blown by the fan can blow the thin stems and leaves horizontally and into the inside of the collection box, which will then sort the thin stems and leaves. The air inlet plays the role of air intake, and the reciprocating motor is turned on by the forward and reverse operations. The reciprocating motor drives the reciprocating gear to rotate. Under the sliding cooperation of the rack and the integrated plate, the reciprocating gear drives the two sets of racks to move back and forth. The rack drives the fan to move back and forth through the support block. The fan blows air evenly to the falling rapeseed and thin stems and leaves through reciprocating swing, thereby improving the effect of blowing away the thin stems and leaves, realizing convenient circular rotation screening of rapeseed, and facilitating the reciprocating swing and even blowing away of the thin stems and leaves in the rapeseed.

[0017] The rapeseed after being blown slides down the material guide slope to the inside of the screening frame, and the servo motor drives the rotating disk to rotate through the articulated shaft. Since the long connecting arm is located at the eccentric position of the rotating disk, the rotating disk drives the long connecting arm to swing back and forth, and the long connecting arm drives the short connecting arm to swing back and forth through the pin shaft, and the short connecting arm drives the screening frame to move back and forth, and the screening frame shakes and finely screens the rapeseed again, thereby completing the rapeseed impurity removal operation and improving the rapeseed impurity removal effect.

A track 16 is symmetrically installed on the inner wall of the integrated box 1 below the material guide slope 13, and two groups of integrated plates 11 are installed on the inner wall of the integrated box 1 on the side of the air inlet 7;

[0026] First, pour the rapeseed mixed with dry stems and leaves into the interior of the screening drum 4, turn on the drive motor 5, and the drive motor 5 drives the transmission gear 10 to rotate through the drive shaft 9. Under the mutual engagement of the transmission gear 10 and the gear ring 8, and the active cooperation of the screening drum 4 and the screening box 2, the transmission gear 10 drives the screening drum 4 to rotate through the gear ring 8, wherein the rapeseed and thin stems and leaves smaller than the diameter of the holes on the surface of the screening drum 4 will fall through the holes, and the stems and leaves larger than the diameter of the holes will be discharged from the interior of the screening drum 4 under the guiding action of the guide bar 3, and turn on the fan 19 to blow the falling rapeseed and thin stems and leaves. The weight of the rapeseed is greater than the wind force of the fan 19, so the wind blown by the fan 19 can move the thin stems and leaves horizontally. The rapeseed and the thin stems and leaves are blown away and enter the interior of the collection box 6, which collects the thin stems and leaves. The air inlet 7 plays the role of air intake. The forward and reverse operations turn on the reciprocating motor 12, and the reciprocating motor 12 drives the reciprocating gear 17 to rotate. Under the mutual meshing of the reciprocating gear 17 and the rack 18, and the sliding cooperation between the rack 18 and the integrated plate 11, the reciprocating gear 17 drives the two sets of racks 18 to move back and forth, and the rack 18 drives the fan 19 to move back and forth through the support block 20.

The rapeseed after blowing slides through the material guide slope 13 to the inside of the screening frame 15, and the servo motor 14 drives the rotating disk 24 to rotate through the hinge shaft 26. Because the long connecting arm 22 is located at the eccentric position of the rotating disk 24, the rotating disk 24 drives the long connecting arm 22 to swing back and forth, and the long connecting arm 22 drives the short connecting arm 23 to swing back and forth through the pin shaft 25. Under the sliding support of the movable wheel 21 and the track 16, the short connecting arm 23 drives the screening frame 15 to move back and forth, and the screening frame 15 shakes and finely screens the rapeseed again, thereby completing the rapeseed removal operation.
