Description

A kind of two-way padding device for laying rapeseed in the middle of swathing and sunning

technical field

The invention relates to a rapeseed windrowing and drying machine, in particular to a two-way pair of arms and a mid-laying reeling device for rapeseed windrowing and drying.

Background technique

Rapeseed cutting and drying is an important link in the segmental harvesting of rapeseed. The reeling device mainly plays the role of pulling, supporting, transporting and laying the cut rapeseed. The reeling device of the existing rapeseed windrower is mainly based on side laying. When laying rape on the side, it is usually spread in the furrows on both sides of the rapeseed windrower through the reeling mechanism, which will affect the progress of the machine to a certain extent, and there are factors such as lack of ventilation when the rape is side laid in the furrows, and mold may occur. Detrimental effects on the quality and yield of rapeseed. Therefore, a kind of rapeseed laying in the middle can be realized, and the two-way paired arm middle laying reeling device is designed, which is used to hang on the high clearance tractor; at the same time, the rape laid on the middle cutting stubble has a certain degree of ground clearance. The gap can improve the ventilation effect and reduce mildew, and it will also facilitate the mechanical operation of picking up rapeseed after it is cooked, and will also effectively avoid the impact on the machine's progress.

Detailed ways

As shown in Fig. 1-Fig. 4, a kind of two-way right-handling mid-laying reeling device for rape for cutting and sunning of the present invention includes a frame 14, and the two sides in front of the frame 14 are respectively provided with grain guide plates 13, and the two sides are guided Leave the laying space 15 between the grain boards 13, and the grain guiding boards 13 on both sides are provided with multi-layers respectively, are arranged as three layers in the present embodiment, leave the grain picking gap 16 between each layer of the grain guiding boards 13, with It plays a guiding role for the rapeseed and achieves the purpose of laying in the middle. On the frame 14 of both sides grass guide plate 13 rears, rotary supporting device is arranged respectively, and this rotary supporting device comprises the installation frame 11 that is arranged on frame 14 upper and lower two places, welding arched plate 9 on the installation frame 11, arched The plate 9 is fixedly connected with the elliptical plate 10 with bolts. The front end protruding shaft 51 of the first eccentric driving rod 5 is connected with the elliptical plate 10 above through the first bearing 4, and the top of the front end protruding shaft 51 of the first eccentric driving rod 5 is fixedly connected to the second sprocket 2'. The rear end protruding shaft 51' of the second eccentric driving rod 5' is connected with the elliptical plate 10 below through the second bearing 6. The rear end of the first eccentric drive rod 5 is pivotally connected to one end of the support member 7, the other end of the support member 7 is pivotally connected to the front end of the second eccentric drive rod 5', and the middle part of the support member 7 is fixedly arranged with multiple rods in the same vertical direction. The driving rod 8 on the top is set as three driving rods 8 in this embodiment, and each driving rod 8 is respectively equipped with a finger 17 relative to the reeling gap 16, and the first and second eccentric driving rods 5, 5' are driven to support When the parts 7 rotated, the finger 17 rotated thereupon, and stretched out the reeling gap 16, and then retreated in the grain guide plate 13. Also be provided with motor 1 in the frame 14, first sprocket 2 is set on the output shaft of this motor 1, is connected by chain 3 between the first and second sprocket 2,2'. One end of the connecting rod 12 is also pivotally connected to the supporting part 7, and the other end of the connecting rod 12 is pivotally connected to one end of the rocking bar 18, and the other end of the rocking rod 18 is fixed on the frame 14. The length of the connecting rod 12 is 450mm, and the rocking bar 18 The length is 120mm, so that the first eccentric drive rod 5, connecting rod 12, and rocking bar 18 form a crank rocker mechanism. Play a role in supporting and limiting the supporting part 7, so as to avoid its excessive swing. In the encircling cuddling state, the fingers on both sides move towards each other synchronously, and the fingers on both sides are staggered from each other.

The reeling device of the present invention adopts the design of articulated high clearance tractor.

During specific work, the second sprocket 2' on the side of the first bearing 4 is driven by the first sprocket 2 on the motor 1 to drive the chain 3 to rotate, so that the first eccentric drive rod 5 performs a 360-degree rotary motion thereupon, and is installed on the The support part 7 at the rear end of the first eccentric drive rod 5 rotates with the first eccentric drive rod, and the driving rod 8 fixed on the support part 7 moves accordingly, so that the two groups of fingers 17 arranged symmetrically on the left and right are pressed at a certain angle. Stretch out the reeling gap 16 opposite to each other, because the fingers 17 on both sides are mutually staggered, the fingers 17 on both sides will carry out the action of helping the rape and reeling the rape in an encircling state, and the rape will be moved under the action of the fingers 17 on both sides. Reeling, conveying, and laying down in the laying space 15 in the middle, then the finger 17 returns to the grain guide plate 13 at a certain angle to enter the next reeling cycle. When the windrower advances, the accumulated rapeseed will provide a part of the push force to the allocated rapeseed to assist in laying, and finally the rapeseed will fall on the stubble. In order to adapt to the plant characteristics of rapeseed with many branches at the top, the spatial distribution of the lever 8 is different, dense at the top and sparse at the bottom, respectively 244mm and 299mm from top to bottom, and the vertical distribution distance of the fingers on both sides is staggered by 20mm.
