Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

A harvester for rod-like crops, as shown in fig. 1 to 5, comprises a frame 1, a cutting and conveying assembly 2 and a knotting assembly 3.

As shown in fig. 1, a cutting conveyor assembly 2 is provided on the frame 1 for cutting and conveying the crop transversely.

A knotting assembly 3 is arranged on the frame 1 for collecting the crop delivered from the cutting conveyor assembly 2. In particular, the knotting assembly 3 comprises a stator 31, at least two sets of reciprocally oscillating rockers 32, a release plate 33 and a bale 34. Referring to fig. 2, the stator 31 is fixedly disposed on the frame 1. The rocker 32 is arranged on the fixed block 31, a motor can be arranged in the fixed block 31, and then the rocker 32 is driven to swing back and forth. The release plate 33 is intermittently swung by the controller to be set on the fixed block 31, and when the rod-shaped crops are piled up to a certain amount, the release plate 33 is opened to release the pile of the rod-shaped crops, and then the release plate 33 is reset. Here, the rocker 32 is arc-shaped, the release plate 33 is provided with an arc corresponding to the rocker 32, and the rocker 32 and the release plate 33 together grip the rod-shaped crop. The bale 34 is arranged on the frame 1 for moving the binding rope and cutting the binding rope at regular time, that is, the binding rope moves from the bale 34 to the release plate 33, and then the binding rope binds the tight rod-shaped crop. Preferably, an auxiliary rod 35 is further designed, the auxiliary rod 35 is fixedly arranged on the fixed block 31, and the auxiliary rod 35 is provided with an arc shape corresponding to the rocker 32. Since the height of the rod crop is large, the stability of the rod crop may not be maintained only by the release plate 33, and the stability can be improved by the auxiliary rod 35. Here, the auxiliary rod 35 is in a fixed state, and the rod-shaped crop is pushed out from the plate at the bottom end of the rocker 32 by the action of the rocker 32, and the rod-shaped crop is pushed down from the plate in an inclined manner, i.e., in an inclined push-out manner.

as shown in fig. 3 and 4, the cutting conveyor assembly 2 includes a cutting blade 21, at least two rows of sprockets 22, a plurality of paddles 23, a plurality of guards 24 and a plurality of planetary gears 25. The cutting blade 21 is arranged on the frame 1, and the cutting blade 21 reciprocates for cutting crops. The chain wheel 22 is transversely and rotatably arranged on the rack 1, the poking sheets 23 are arranged on the chain wheel 22, the poking sheets 23 are used for poking crops, specifically, rod-shaped crops are arranged between the two poking sheets 23, the chain wheel 22 is provided with at least two rows, the chain wheel 22 is arranged behind the harvested rod-shaped crops, and when the harvester moves forwards, the chain wheel 22 can assist the rod-shaped crops.

The guard plate 24 is arranged on the frame 1, the guard plate 24 is arranged opposite to the chain wheels 22, each group of star wheels 25 is rotatably arranged on the guard plate 24, and the star wheels 25 are arranged opposite to the shifting pieces 23 and used for keeping crops to vertically move. The rod crop is between the star wheel 25 and the paddle 23, the star wheel 25 and the paddle 23 together conveying the rod crop therebetween. Preferably, the poking piece 23 is arc-shaped, when the poking piece 23 moves towards the knotting assembly 3, the arc center of the poking piece 23 faces towards the knotting assembly 3, and the moving arc-shaped poking piece 23 can keep the rod-shaped crops on the inner side of the poking piece 23 as much as possible during the movement. The star wheel 25 is also arc-shaped, but the star wheel 25 is different from the paddle 23 in that the arc center is opposite to the star wheel 25. In addition, the star wheel 25 is passively arranged on the star wheel 25, rod-shaped crops moving in the horizontal direction can drive the star wheel 25 to rotate, energy consumption is reduced, and mismatching between the star wheel 25 and the poking piece 23 due to electric control is avoided. The guard plate 24 is arranged obliquely, and the bottom end of the guard plate 24 is arranged to be in a sharp angle shape, and the sharp angle shape is used for clearing obstacles when the harvester moves forwards.

the application also designs a straw returning wheel 4, and the straw returning wheel 4 comprises a supporting frame 41, a turntable 42, a plurality of groups of rotating rods 43 and a harrow bar 44. The supporting frame 41 is arranged on the frame 1 and above the cutting and conveying assembly 2. The rotary tables 42 are rotatably disposed on the supporting frame 41, and at least two rotary tables 42 are disposed on two sides of the supporting frame 41. The rotary lever 43 is rotatably provided on the turntable 42, and the raker lever 44 is provided on the rotary lever 43, so that the raker lever 44 can always be kept in a vertically downward state when the turntable 42 is rotated. The rake bar 44 is used to push the crop back so that it falls towards the cutting conveyor assembly 2.

when the rod crop harvester is used, the cutting blade 21 cuts the rod crops and transports the rod crops to one side under the action of the shifting blade 23 and the star wheel 25, and the bottom ends of the rod crops move on the cutting blade 21. Under the action of the rocker 32, the crops are gradually piled up at the rotating rod 33, and the bale 34 binds the binding rope to the middle of the crops. As the number of the rod-shaped crops increases, the release plate 33 is opened, the rod-shaped crops are pushed to the outside, and the rod-shaped crops fall out in a pile-like manner due to a certain adhesion between the rod-shaped crops.

It should be understood that the above embodiments are only for illustrating the technical solutions of the present invention, and not for limiting the same, and it is obvious for those skilled in the art that the technical solutions described in the above embodiments can be modified or some technical features can be replaced equivalently as long as no structural conflict exists; and all such modifications and alterations are intended to fall within the scope of the appended claims.
