Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-2, the tail end actuating mechanism of the broccoli harvesting mechanism comprises a transmission mechanism 1, a harvesting blade 3 and a driving device 2. There are four through-holes above mounting bracket 22, unscrew four bolts on the step motor 21 one side, pass mounting bracket 22 and fix on mounting bracket 22, and mounting bracket 22 is L type support. Through the rotation control of step motor 21 for crank 23 carries out the circular rotation around step motor 21's output, and rocker 24 is connected through bolt and nut to the other one end of crank 23, and connecting rod 11 that the other one end rethread bolt of rocker 24 and nut link to each other to link together with rocker 24 through bolt and nut. When the connecting rod is used, the connecting rod 11 can be limited in the through hole, so that the connecting rod 11 is prevented from moving transversely and can only move up and down in the vertical direction. The bottom end of the connecting rod 11 is in threaded connection with a through threaded hole and a nut in the center of the cross bracket 12.
The tail end of the cross support 12 is provided with four threaded holes distributed in a circumferential array and in threaded connection with four rod end joint bearings 13, four fisheye rod end joints are adopted in the embodiment, the inner core 131 is respectively connected with spherical connectors 141 of four double-end connecting rods 14, a hinge buckle 142 is arranged at the other end of each double-end connecting rod 14 and is connected with a hinge rod 31 of the cutting blade 3 in a matched mode through the hinge buckle, and the double-end connecting rods 14 are matched with the cutting blade 3 in a hinged mode. Finally, the following processes are realized: when the stepping motor 21 rotates, the crank 23 of the output shaft drives the rocker 24 to rotate, and the connecting rod 11 drives the cross bracket 12 to move up and down, so that the four rod end joint bearings 13 on the cross bracket 12 move up and down, and meanwhile, the inner core 131 of the rod end joint bearing 13 can rotate freely, so that the cutting blade 3 is driven to realize two actions of cutting and retracting.
When the rod end joint bearing 13 is installed on the cross bracket 12, although the orientation position of the rod end joint bearing can be random due to the characteristic that the inner core 131 of the rod end joint bearing can move randomly, the rod end joint bearing is ensured to rotate to a reasonable position when being installed, and the horizontal surfaces of the four rod end joint bearings 13 are respectively in a 90-degree array and are optimal outwards.
The vertical portion of the mounting frame 22 is cut away to ensure that the crank 23 and the rocker 24 do not collide with the plane of the mounting frame 22 during movement.
The driving device 2 can also be an air cylinder, the output end of the air cylinder is fixedly connected with the connecting rod 11, and the connecting rod 11 can drive the cross-shaped support 12 to move up and down to a specified position. A certain pressure strain gauge can be adhered to a reasonable position above the cutting blade 3, and the system can be fed back to know whether the sleeve is provided with the broccoli or not.
In view of the lower cost that can be achieved, the spider 12 can be modified to be a single disc with two holes cut therein and the bulbous end of the double-ended link can be modified to be a flat surface with a through hole, with a pair of blades connected to two holes in the disc using pins, and the other set of blades omitted, making the end effector mechanism simpler and less costly.
With reference to fig. 3-4, the mechanism of the present invention is mounted in the sleeve when in use. The bottom of the sleeve is provided with an opening and a built-in cavity, the transmission mechanism 1 is arranged in the inner cavity, and the driving device 2 and the cutting blade 3 are respectively arranged at the upper end and the lower end of the sleeve. The upper part of the connecting rod 11 passes through a central hole above the sleeve, so that five degrees of freedom of the connecting rod 11 are limited, only the vertical up-and-down motion can be carried out,
there are 4 through holes above the sleeve for fixing the mounting bracket 22 and the sleeve together by means of nuts and bolts. Four rectangular grooves are formed in the outer wall of the sleeve, a cutter groove is formed in the bottom of the sleeve, a notch is formed above the cutter groove 7, and the rotation of the double-end connecting rod 14 is limited through the rectangular grooves and the notch limiting.
Cutting blade 3 moves on the spout of inslot portion, and the space between spout 1 and cutting blade 3 will guarantee that the blade is in the smooth while of moving, and the clearance is as little as possible for cutting blade 3 can not move about and influence cutting effect. The fisheye inner core 131 inside the rod end knuckle bearing 13 can rotate up and down, left and right at will, but because the double-end connecting rod 14 is limited by the four rectangular grooves on the sleeve and the slots on the cutter grooves, the inner core 131 can only rotate up and down along with the double-end connecting rod 14.
When the cutting device is used, the driving device 2 is utilized to drive the cutting blade 3 to cut inwards, so that the cutting and picking of the roots of broccoli are realized by utilizing a single harvesting mechanism conveniently and effectively. And carry out the short time after the cutting of broccoli root and accomodate, have convenient to use safety, work efficiency is high, and stability is good, low in production cost's characteristics.
