Technical Field
The utility model belongs to the agricultural harvester field, in particular to double-action knife device suitable for cutting of regeneration rice ear of grain head.
Background
The regenerated rice is rice which can be harvested twice after one crop, and after the first-season rice is harvested, the pile is left for tillering and sprouting to obtain the second-season rice ears. The moisture content of the regenerated rice is higher compared with that of the traditional rice during harvesting, and in order to reduce the internal load of the harvester, the ear heads with a small amount of stalks only need to be cut under the condition of ensuring the poor ear amplitude to enter the harvester. The traditional harvester adopts a cutter of a 'certain moving' type, wherein a fixed cutter and a blade protector play roles of fixedly supporting and protecting a moving blade, so that the fixed cutter and the blade protector are used for cutting stalks which are relatively close to the ground and have large diameters, the power consumption is too large when the fixed cutter and the blade protector are used for harvesting the regenerated rice in the first season, the speed is low, the fixed cutter and the blade protector are not suitable, and therefore, a novel harvesting cutter is necessary to be researched aiming at the characteristic that the regenerated rice in the first season only needs to cut the head part with small diameter.

Detailed Description
The following describes the present invention with reference to the following embodiments. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in figure 1, the double-knife device suitable for cutting the head of the regenerated rice comprises an upper blade component and a lower blade component, wherein the upper blade component is arranged above the lower blade component. As shown in fig. 2, the upper blade assembly includes a plurality of upper blades 11, an upper blade fixing strip 12, and an upper blade moving strip 13, where the upper blade fixing strip 12 and the upper blade moving strip 13 are located in the same horizontal plane and are parallel to each other, and the tool shanks of the plurality of upper blades 11 are respectively hinged to the upper blade fixing strip 12 and the upper blade moving strip 13. As shown in fig. 3, the lower blade assembly includes a plurality of lower blades 21, a lower blade fixing strip 22, and a lower blade moving strip 23, the lower blade fixing strip 22 and the lower blade moving strip 23 are respectively located below the upper blade fixing strip 12 and the upper blade moving strip 13 and are parallel to each other, and the tool shanks of the plurality of lower blades 21 are respectively hinged to the lower blade fixing strip 22 and the lower blade moving strip 23. The upper blade 11 and the lower blade 21 form a V-shaped included angle.
As shown in fig. 2 and 3, an upper knife sliding groove 15 is formed at the hinged position of the tail part of the knife handle of the upper knife blade 11 and the upper knife movable blade 13; the hinged part of the tail part of the lower blade 21 and the lower movable blade strip 23 is provided with a lower blade sliding groove 25. The upper cutter moving blade 13 and the lower cutter moving blade 23 are respectively provided with two long circular holes, the upper cutter fixing strip 12 and the upper cutter moving blade 13 are respectively connected through a connecting rod, the lower cutter fixing strip 22 and the lower cutter moving blade 23 are respectively connected through a connecting rod, and one end of the connecting rod, which is connected with the upper cutter moving blade 13 and the lower cutter moving blade 23, is connected with a pin shaft arranged in the long circular holes.
The upper knife sliding guide mechanism 14 and the lower knife sliding guide mechanism 24 which are composed of the connecting rod, the pin shaft and the long round hole play a role in limiting the distance between the upper knife fixing strip 12 and the upper knife moving strip 13 as well as the distance between the lower knife fixing strip 22 and the lower knife moving strip 23 when the upper knife moving strip 13 and the lower knife moving strip 23 transversely move left and right, and guarantee the consistent distance and the guiding function; the sliding groove design of the tail parts of the handles of the upper blade 11 and the lower blade 21 can enable the rotating shaft at the hinged positions of the tail parts of the handles of the upper blade and the lower blade to slide relative to the handles of the lower blade and the movable blade 13, and prevent the rotating shaft from being driven by the tail parts of the handles of the upper blade and the lower blade to move in the front-back direction when the upper blade 11 and the lower blade 21 rotate. Therefore, the upper movable cutter strip 13 can not move in the front-back direction when driving the upper blade 11 to rotate and the lower movable cutter strip 23 can not move when driving the lower blade 21 to rotate, and the running stability of the whole device is improved.
