Detailed Description As shown in Figs. 1-10, the present invention mainly comprises a rack 1, a poking mechanism, a downward moving mechanism, a cutting mechanism, a transfer mechanism and a collecting mechanism. The present invention is described in detail below in combination with the drawings.

As shown in Fig. 1, the rack 1 is a main component of the present invention and is provided with a walking mechanism so as to have the self-walking ability. Handrails 11 are disposed on the front side of the rack for adjusting a walking direction of the rack. A collecting groove 2 is formed in the front side of the rack and used for temporarily storing corn ears. The rack is provided with a transition groove 3 which is inclined; the front end of the transition groove is relatively low, and the rear end of the transition groove is relatively high; the front end of the transition groove is connected with the rear end of the collecting groove together; the collecting groove and the transition groove form the collecting mechanism; and the collecting mechanism is used for collecting the corn ears.

The rack is provided with a driving assembly 4 used for driving other mechanisms on the rack.

The poking mechanism is arranged at the rear end of the rack and, and as shown in Fig. 2, comprises a pair of symmetric clamping plates 5; each clamping plate comprises two sections arranged with an obtuse angle; the front ends of the two clamping plates are parallel to each other; and the rear ends of the two clamping plates are in an inverted splayed shape. When in use, a corn plant moves from the rear side relative to the clamping plates to enter a space between the two clamping plates; and the corn plant are facilitated to enter the space as the rear ends of the clamping plates are in the inverted splayed shape. In order to avoid moving out the corn plant, a pair of chain transmission mechanisms are disposed on the lower sides of the clamping plates.

As shown in Fig. 3, each chain transmission mechanism comprises a pair of chain wheels 51 and a chain 53 connecting the two chain wheels; a plurality of uniformly disposed poking blocks 52, each of which is of a cuboid or cylinder structure, are fixedly disposed on the chain; the poking blocks on the two chain transmission mechanisms are in one-to-one correspondence; and the two corresponding poking blocks are matched with each other to act to block and limit the corn plant. As shown in Fig. 4, the corn plant is located between two adjacent pairs of poking blocks and then is poked to move towards the front side of the rack. The downward moving mechanism is disposed below the poking mechanism and, and as shown in Fig. 5, comprises two groups of ear plates 72. Conveying rollers 7 are disposed between two grouped ear plates; a plurality of pressing strips 71 which are uniformly arranged in a circumferential direction are disposed on the outer wall of each conveying roller; and the two conveying rollers are opposite in rotation directions. The two conveying rollers are matched with each other to act to extrude and convey downwards the corn plant, and then the corn plant moves downwards.

The cutting mechanism is disposed below the downward moving mechanism and as shown in Fig. 5, comprises a pair of horizontally disposed cutters 8 and motors 81 for driving the cutters to rotate; and the two cutters are matched with each other to act to cut the corn plant when rotating. An interval between the outer edges of the two cutters is very small, so as to ensure the corn plant may be cut. The transfer mechanism is disposed above the clamping plates and as shown in Fig. 7, comprises a first transfer plate 9 and a second transfer plate 91 which are horizontally disposed, and the first transfer plate and the second transfer plate are inclined and coplanar with each other. In the process of downward movement of the corn plant, after the corn ears move to the position between the first transfer plate and the second transfer plate, as the interval between the front ends of the clamping plates is smaller than the outside diameter of the corn ears, the corn ears can be blocked by the first transfer plate and the second transfer plate, then the corn ears and the corn plant are mutually pulled, and finally, the corn ears are pulled down from the corn plant. Thereafter, the corn ears roll downwards onto the transition groove along the second transfer plate, and then, as shown in Fig. 9, roll downwards into the collecting groove along the transition groove to achieve collection of the corn ears.

As shown in Fig. 8, the corn plant sequentially has a cutting point 61, an extrusion point 62, a poking point 63 and an ear separating point 64 from root upwards; the cutters cut the corn plant at the cutting point; the conveying rollers are in contact with the corn plant at the extrusion point; and then the corn plant is conveyed. The poking blocks are in contact with the corn plant at the poking point to poke the corn plant, and the corn ears 65 drop onto the second transfer plate at the ear separating point. As shown in Fig. 10, in order to ensure that the poking blocks annularly move in a direction of the corresponding chains, guide blocks 54 are fixedly disposed on the upper surfaces of the poking blocks, chutes are formed in the bottoms of the clamping plates, the guide blocks are put into the chutes and then are slidably connected with the clamping plates, and the poking blocks move along the annular chutes.

When the present invention is used, in the walking process of the rack, the corn plant enters the space between the clamping plates, then enters the front ends of the clamping plates after being poked by the poking mechanism, is cut by the cutting mechanism and is dragged downwards by the downward moving mechanism, and the corn ears are separated from the corn plant by the first transfer plate and the second transfer plate and then are transferred into the collecting groove by the transfer mechanism. The present invention is simple in structure and may intelligently harvest the ears of the fresh corns.
