DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, a multi-stage screening nut shelling and kernel extraction and nut kernel crushing and shell separation machine includes a long strip box body 1, in which a plurality of partitions 2 are welded and evenly spaced front and back along the length direction thereof, and the plurality of partitions 2 divide the inner cavity of the box body 1 into a plurality of shelling chambers 3 which are transparent from top to bottom, and a shelling assembly is respectively arranged in the plurality of shelling chambers 3.

[0030] The upper end of the box body 1 is provided with a screening frame 5 which is transparent from top to bottom. Figure 3As shown, a screening channel 6 is provided in the screening frame 5 for nuts to fall into the box body 1, and the screening channel 6 gradually widens from the back to the front along the length direction of the box body 1. Specifically, a plurality of support rods 7 evenly spaced left and right along the width direction of the box body 1 are fixedly installed between the front and rear side walls of the screening frame 5 by bolts, and the support rods 7 extend forward and backward along the length direction of the box body 1, and the outer diameter of the support rods 7 gradually decreases from the back to the front, and a screening channel is provided between two adjacent support rods 7.

[0031] When in use, the nuts to be shelled are put into the screening frame 5 corresponding to the narrower end of the screening channel 6. Since the rear end of the support rod 7 is thicker and the front end is thinner, the nuts put into the screening frame 5 will roll forward along the support rod 7 and the screening channel 6 toward the thinner end of the support rod 7 until the nuts roll to the position where the width of the screening channel 6 is greater than the diameter of the nuts and fall downward through the screening channel 6, so that nuts of different diameters fall downward through different positions of the screening channel 6 into the corresponding shelling chamber 3, and are respectively shelled by the corresponding shelling components.

[0032] In this embodiment, if Figure 2 As shown, the shell breaking assembly includes two squeezing rollers 8 arranged in parallel in the shell breaking chamber 3, and the two ends of the squeezing rollers 8 are respectively connected to the housing 1 by bearings, and the two squeezing rollers 8 are driven by a power mechanism to rotate in opposite directions. For example, one end of the two squeezing rollers 8 is meshed by gears, and one end of one of the squeezing rollers 8 is also connected to a driving motor, so that the driving motor drives the two squeezing rollers 8 to rotate in opposite directions to squeeze and break the nuts; a shell breaking channel 9 is provided between the two squeezing rollers 8, and the shell breaking channels 9 located in different shell breaking chambers 3 have different widths. Specifically, the width of the multiple shell breaking channels 9 increases from back to front. Specifically, the width of the shell breaking channel 9 in the shell breaking chamber 3 corresponding to the narrower part of the screening channel 6 is narrower, and the width of the shell breaking channel 9 in the shell breaking chamber 3 corresponding to the wider part of the screening channel 6 is wider, so that the nuts falling downward through the screening channel 6 of the corresponding width are adaptively broken through the shell breaking channel 9 to ensure the shell breaking efficiency.

[0033] In addition, a guide plate 10 is welded in the shell breaking chamber 3 for guiding the nuts to the upper end of the corresponding shell breaking channel 9. Two guide plates 10 are arranged opposite to each other in the front and rear, and the two guide plates 10 are arranged in an inverted eight shape to prevent the nuts from falling to the outside of the two squeezing rollers 8.

[0034] like Figure 2 and Figure 4As shown, a funnel-shaped receiving hopper 11 is fixedly installed at the lower end of the box body 1 by bolts, the lower end of the box body 1 is connected with the upper end of the receiving hopper 11, a separation tube 12 is welded at the lower end of the receiving hopper 11, the lower end of the receiving hopper 11 is connected with the separation tube 12, the rear end of the separation tube 12 is closed, and the front end is inclined and lowered, a throwing assembly for promoting the separation of kernels and shells is provided in the separation tube 12, the throwing assembly includes a plurality of levers 13 evenly spaced around the axis of the separation tube 12, the levers 13 extend along the length direction of the separation tube 12 and the levers 13 are in contact with the inner wall of the separation tube 12, the rear ends of the plurality of levers 13 are welded to the same annular first retaining frame 14, the first retaining frame 14 is connected to a first power component for driving the plurality of levers 13 to rotate around the axis of the separation tube 12. The first power component is specifically the first motor 15, which is installed on the outer side of the rear end of the separation tube 12 by bolts. The rotating shaft of the first motor 15 is coaxially arranged with the separation tube 12, and a connecting plate is welded inside the first retaining frame 14, and the connecting plate is fixedly connected to the rotating shaft of the first motor 15.

[0035] After the nuts are squeezed and shelled by two squeezing rollers 8, the shelled kernels and shells first fall downward through the receiving hopper 11 into the interior of the separation tube 12, and slide forward along the inclined separation tube 12. In the process of the kernels and shells sliding out through the front end of the separation tube 12, the first motor 15 drives multiple levers 13 to rotate in the separation tube 12. The multiple levers 13 continuously toss the kernels and shells in the separation tube, thereby promoting efficient separation of the kernels and shells and preventing the kernels and shells from sticking together. Finally, the separated kernels and shells slide out from the front end of the separation tube 12.

[0036] In addition, in order to improve the connection strength of the multiple levers 13 and reduce the deformation of the levers 13, the lower ends of the multiple levers 13 are welded to the same annular second retaining frame 16; the first retaining frame 14 is located inside the high end of the separation tube 12, and the second retaining frame 16 extends outward from the lower end of the separation tube 12 to prevent the second retaining frame 16 from blocking the kernels and shells from sliding out through the front end of the separation tube 12.

[0037] like Figure 1 and Figure 2As shown, a stand 17 is provided at the rear side of the box body 1, and a discharge hopper 18 is fixedly installed on the stand 17 by bolts. The discharge hopper 18 is used to store nuts to be shelled. The upper end of the discharge hopper 18 is funnel-shaped, and the lower end is a circular arc extending laterally. A discharge pipe 19 is provided at the front side of the bottom wall of the discharge hopper 18. The front end of the discharge pipe 19 extends downward at an angle, and the front end of the discharge pipe 19 faces the top of the screening frame 5 corresponding to the narrower end of the screening channel 6. In this embodiment, a receiving plate 20 is welded to the rear end of the screening frame 5. The front end of the receiving plate 20 is connected to the screening frame 5, and the rear end extends upward at an angle and extends to the bottom of the discharge pipe 19, so that the nuts in the discharge hopper 18 can slide along the receiving plate 20 to the rear end of the screening frame 5 after being discharged through the discharge pipe 19. In addition, the left and right sides of the receiving plate 20 are respectively provided with side plates bent upward to prevent nuts from falling out from the side of the receiving plate 20.

[0038] like Figure 1 and Figure 5 As shown, a discharge roller 21 driven by a second power component and rotating around its own axis is provided in the lower end of the discharge hopper 18, the axis of the discharge roller 21 extends horizontally, and both ends of the discharge roller 21 are rotatably connected to the discharge hopper 18 through bearings, the second power component is specifically a second motor 22 installed on the stand 17 by bolts, and one end of the discharge roller 21 is connected to the rotating shaft of the second motor 22 through a coupling. The outer wall of the discharge roller 21 fits the inner wall of the lower end of the discharge hopper 18, and the outer wall of the discharge hopper 18 blocks the high end of the discharge pipe 19, thereby preventing the nuts in the discharge hopper 18 from being discharged in large quantities through the discharge pipe 19 in a short time.

[0039] A plurality of conveying grooves 23 for nuts to enter are evenly distributed on the outer peripheral surface of the discharge roller 21. The discharge roller 21 is driven to rotate by the second motor 22. When the discharge roller 21 drives the conveying groove 23 to rotate to the top of the discharge roller 21, the nuts in the discharge hopper 18 enter the conveying groove 23; when the discharge roller 21 drives the conveying groove 23 to rotate to the discharge pipe 19, the nuts in the conveying groove 23 at the discharge pipe 19 fall out and are put into the screening frame 5 through the discharge pipe 19, thereby controlling the discharge speed of the nuts in the discharge hopper 18 and improving the accuracy of nut screening.

[0040] like Figure 1As shown, the lower end of the screening frame 5 is inserted into the upper end of the box body 1, and two first support plates 24 arranged opposite to each other are fixedly installed on the left and right sides of the screening frame 5, and a second support plate 25 corresponding to the first support plate 24 is fixedly installed on the box body 1, and the second support plate 25 is located below the corresponding first support plate 24, and a spring 26 is connected between the corresponding first support plate 24 and the second support plate 25, and the two ends of the spring 26 are respectively connected to the first support plate 24 and the second support plate 25 by welding or bolts. When the nuts are discharged through the discharge pipe 19 and fall into the receiving plate 20 or the screening frame 5, the knocking action of the nuts can drive the screening frame 5 to vibrate up and down, thereby efficiently prompting the nuts to roll forward along the support rod 7 and the screening channel 6, thereby improving the screening efficiency of the nuts.
