Description

Rapeseed Combine Harvester Special Cutter Device

technical field

The utility model relates to agricultural machinery, in particular to a special cutter device for a rapeseed combine harvester.

Background technique

Combined harvesting of rapeseed has high efficiency, saves labor and time, and is conducive to rush harvesting especially in bad weather conditions. It is a necessary means to improve the efficiency of rapeseed planting and realize the mechanization of rapeseed production. However, this method has strict requirements on the timing of harvesting, neither earlier nor later. Rapeseed pods are easy to crack and lose seeds when they are mature, which requires no large vibration and impact during harvesting. The existing rapeseed combine harvesters are all reformed from full-feed rice-wheat combine harvesters. The knives are a combination of moving knives and fixed knives. The fixed knives only move forward with the whole machine during harvesting, and there is no horizontal cutting movement. During the operation, they will collide with the rape stalks and cause the rape and the header to vibrate, which will easily cause the mature rape pods to crack and fall off. seeds, header losses increase. This is also one reason why the promotion of rapeseed combine harvesters is slow.

Utility model content

The technical problem to be solved by the utility model is to provide a special cutter device for rapeseed combine harvesters, so as to effectively enhance the cutting effect of the cutter and reduce the loss of the header.

The technical solution adopted by the utility model to solve its technical problems is as follows:

The special cutting knife device for rapeseed combine harvester of the utility model is characterized in that it includes a lower moving knife group and an upper moving knife group which can slide left and right and are installed on the cutting knife seat plate. A left transmission mechanism is arranged between the moving knife groups, and a right transmission mechanism is arranged between the header feeding roller shaft and the upper moving knife group 3 .

The beneficial effect of the utility model is that the dual-action cutter driven by the feed roller shaft of the header is provided, which effectively solves the difficult problem that rape stalks are thicker than rice and wheat stalks and is difficult to cut, and greatly enhances the cutting efficiency of the cutter. The effect can minimize the header loss.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1, the special cutting knife device for the rapeseed combine harvester of the present utility model includes a lower moving knife group 1 and an upper moving knife group 3 which can slide left and right and are installed on the cutting knife seat plate 8, and the feeding roller on the header A left side transmission mechanism is arranged between the shaft 7 and the lower moving knife group 1, and a right side transmission mechanism is arranged between the header feeding roller shaft 7 and the upper moving knife group 3. The double-moving knife structure is composed of the lower moving knife group 1 and the upper moving knife group 3, and is driven by the feeding roller shaft 7 of the header, which effectively solves the problem that rape stalks are thicker than rice and wheat stalks and difficult to cut. The cutting effect of the cutter is greatly enhanced, and the loss of the header can be minimized.

With reference to Fig. 1, described left side transmission mechanism is made of left side eccentric wheel 6a, left side adjusting link member 5a, left side rocker arm 4a, and left side eccentric wheel 6a is fixedly installed on header feed roller shaft 7 left ends, The left rocker arm 4a is hinged on the cutter seat plate 8, the upper end and the lower end of the left side adjusting link member 5a are respectively hinged with the lower end of the left rocker arm 4a and the left eccentric wheel 6a, and the upper end of the left rocker arm 4a moves downward. Knife set 1. The right side transmission mechanism is composed of the right side eccentric wheel 6b, the right side adjusting link member 5b, and the right side rocker arm 4b. 4b is hinged on the cutter seat plate 8, the upper end and the lower end of the right side adjusting link member 5b are respectively hinged with the lower end of the left side rocker arm 4b and the left side eccentric wheel 6b, and the upper end of the right side rocker arm 4b acts on the upper moving knife group 3.

With reference to Fig. 2, described lower moving knife group 1 is made of the blade that upper moving knife bar 3a is fixedly arranged on it, and upper moving knife group 3 is made of the blade that lower moving knife bar 3b is fixedly arranged on it, in cutter seat The plate 8 is provided with movable knife pressure plates 2 at intervals to constrain the sliding direction of the lower movable knife group 1 from the upper movable knife rod 3a. The gap of following movable knife group 1, upper movable knife group 3 guarantees by adjusting the gap between movable knife pressing plate 2 and cutter seat plate 8, and the left and right moving distance is determined by the eccentricity of left side eccentric wheel 6a, right side eccentric wheel 6b.

The above are just some principles of the special cutter device for the rapeseed combine harvester of the utility model with illustrations, and are not intended to limit the utility model to the specific structure and scope of application shown and described, so all possible uses The corresponding amendments and equivalents all belong to the patent scope of the utility model application.
