As shown in fig. 11, the patent application No. 201711374103.4 discloses a broccoli continuous block and core removing device, wherein the blade edges of two hemispherical blades form a spherical track 37-1 (the track is formed by rotating the two hemispherical blades around a fixed hinged point) when moving, and the broccoli bud one 38-1 and the broccoli bud two 38-2 cannot be completely cut off; according to the invention, the blade cutting edges of the two connecting rod cutters form a similar conical track 37-2 when moving (the track is that the two connecting rod cutters rotate around the movable hinge point, and the movable hinge point is driven by the multi-connecting rod mechanism to move), so that the broccoli bud I38-1 and the broccoli bud II 38-2 can be thoroughly separated, and the function of thoroughly partitioning the broccoli is realized.
The working principle of the invention is as follows:
step one, a stepping motor 17 rotates, and a driving shaft is driven to rotate through a chain transmission mechanism; the driving shaft 16 drives the first input shaft 19 to rotate through the second synchronous pulley 10, the synchronous belt 9 and the first synchronous pulley 8; the first input shaft 19 drives the conveying driving chain wheel 14, the conveying chain plate 13 and the conveying driven chain wheel 15 to move through the driving non-circular gear 6 (first-order non-circular gear) and the driven non-circular gear 7 (first-order non-circular gear), and the tray 11 moves along with the conveying chain plate 13.
Step two, the driving shaft 16 rotates to drive the first connecting rod 21, the second connecting rod 22, the cutting block supporting frame 23, the first sliding block 24 and the first linear guide rail 25 to move, so that the cutting block supporting frame 23 moves linearly in a reciprocating mode along the first linear guide rail 25; when the dicing support frame 23 moves to the lowest point, one tray 11 is conveyed by the conveying link plate 13 to the position right below the dicing assembly 4 at a lower (lower than 40% of the highest) conveying speed in the whole conveying period (as shown in fig. 8, the conveying speed is the corresponding tray conveying speed at the rotation radian pi of the stepping motor, and since the design needs to ensure the transmission characteristic of the non-circular gear, it is difficult to design the conveying speed to be the lowest conveying speed in the whole conveying period), and at this time, the controller receives the detection signal of the first sensor 27.
Step three, the controller controls a push rod of the air cylinder 29 to push out, and drives the second sliding block 31 and the connecting rod hinging block 32 to move downwards along the second linear guide rail 33, so that the first cutting connecting rod 34 and the second cutting connecting rod 35 swing; the second cutting block connecting rod 35 swings to drive the third cutting block connecting rod 36 and the connecting rod cutter 37 to swing; the two link cutters 37 are closed to cut off the roots and stems of the broccoli. Because the cutting block component 3 is composed of two groups of symmetrically arranged sliding block rocker mechanisms (composed of a second linear guide rail 33, a connecting rod hinging block 32, a cutting block first connecting rod 34 and a cutting block second connecting rod 35) and double rocker mechanisms (composed of a second linear guide rail 33, a cutting block second connecting rod 35, a cutting block third connecting rod 36 and a connecting rod cutter 37), the similar conical track of the cutting edge of the two connecting rod cutters 37 is realized.
Step four, when the cutting block supporting frame 23 moves to the highest point, the cutting block assembly 4 is located right above the guide-out plate 5, at the moment, the controller receives a detection signal of the second sensor 28, the push rod of the control cylinder 29 retracts, the second sliding block 31 and the connecting rod hinging block 32 are driven to move upwards along the second linear guide rail 33, and the first cutting block connecting rod 34, the second cutting block connecting rod, the third cutting block connecting rod 36 and the connecting rod cutter 37 are driven to swing; the two link cutters 37 are opened to discharge the cut broccoli rhizome.
