In order to improve the harvesting efficiency of crops, the development of a reciprocating type double-action cutting knife driving device suitable for cutting plant stalks has very important significance.
Disclosure of Invention
In order to improve the harvesting efficiency of crops, the utility model provides a reciprocating double-action cutting knife driving device for cutting leaf vegetables.
In order to achieve the purpose, the utility model adopts the technical scheme that: a reciprocating double-acting cutting knife driving device for cutting leaf vegetables comprises an eccentric driving mechanism, a rack slider mechanism and double cutting knives, wherein the eccentric driving mechanism is connected with the double cutting knives through the rack slider mechanism to form the reciprocating double-acting cutting knife driving mechanism for cutting the stems of the leaf vegetables.
Further, the rack sliding block mechanism is composed of two rack sliding blocks, a guide rail and a gear which are oppositely arranged, the two rack sliding blocks which are oppositely arranged are meshed and connected through the gear and are respectively matched and slidably connected with the respective guide rail.
Furthermore, two cutting knives are respectively arranged on the two oppositely arranged rack sliding blocks, and the two cutting knives are arranged in a front-back corresponding manner.
Furthermore, the eccentric driving mechanism consists of an eccentric wheel and a bearing, and the eccentric wheel is connected with a rack sliding block through the bearing.
Furthermore, the bearing is arranged in a square groove in the rack sliding block, and the rack sliding block is driven by the eccentric wheel through the bearing to move back and forth along the guide rail.
Further, the eccentric wheel is connected with a motor or an engine.
The utility model has the beneficial effects that:
compared with the conventional reciprocating cutting device used for harvesting crops, the device adopts a structure of the reciprocating double-action cutting knife, and has the characteristics of small vibration, low requirement on rotating speed, high cutting efficiency and the like.

FIG. 1 is a front view of the structure of a double-acting cutting knife driving device of the present invention;
FIG. 2 is a left side sectional view of the structure of the double-acting cutting knife driving device of the present invention;
FIG. 3 is a schematic view showing the operation of the double-acting cutting knife driving apparatus of the present invention;
wherein: (a) the eccentric wheel is at an initial position, (b) the eccentric wheel rotates 90 degrees counterclockwise, (c) the eccentric wheel rotates 180 degrees counterclockwise, and (d) the eccentric wheel rotates 270 degrees counterclockwise.
Detailed Description
The utility model is further described with reference to the following figures and examples.
As shown in figures 1 and 2, the reciprocating double-action cutting knife driving device for leaf vegetable cutting comprises an eccentric wheel 1, a bearing 2, a rack sliding block I3, a cutting knife I4, a guide rail I5, a guide rail II 6, a rack sliding block II 7, a cutting knife II 8 and a gear 9.
The rack sliding block I3 and the rack sliding block II 7 are respectively installed in the guide rail I5 and the guide rail II 6, the rack sliding block I3 is meshed with the rack sliding block II 7 through a gear 9, the back faces of the rack sliding block I3 and the rack sliding block II 7 are respectively provided with a cutting knife I4 and a cutting knife II 8, the rack sliding block I3 is internally connected with an eccentric wheel 1 through a bearing 2, the eccentric wheel 1 is connected with a motor or an engine, the eccentric wheel 1 is driven by the motor or the engine to drive the rack sliding block I3 and the cutting knife I4 to move along the guide rail I5 through the bearing 2, and the rack sliding block II 7 and the cutting knife II 8 are driven by the gear 9 to move along the opposite directions of the guide rail II 6, so that the cutting knife I4 and the cutting knife II 8 realize cutting of the leaf and stem stalks.
As shown in fig. 3 (a), (b), (c) and (d), the device rotates the eccentric wheel 1 around the center thereof by a motor or an engine, the rotation of the eccentric wheel 1 rotates the bearing 2 around the center of the eccentric wheel 1, the bearing 2 rotates in the rack slider-3, the rack slider-3 slides in the guide rail-5 in a reciprocating manner, and the cutter-4 slides in a reciprocating manner along with the rack slider-3. The reciprocating motion of the rack sliding block I3 drives the gear 9 to rotate in the positive and negative directions, the gear 9 rotates to enable the rack sliding block II 7 to move in the guide rail II 6 in a direction opposite to that of the rack sliding block I3, and the cutting knife II 8 reciprocates along with the rack sliding block II 7. Finally, the cutting knife I4 and the cutting knife II 8 make reciprocating relative motion to realize the cutting of the leaf vegetable stalks.
Due to the functions, the reciprocating type double-action cutting knife driving device can be adapted to machinery for harvesting leaf vegetables and stems such as green vegetables, crowndaisy chrysanthemum, Guangdong flowering cabbage and the like. The device is arranged on the vegetable harvester in a matching way, so that the harvesting quality of vegetables is effectively improved, and the loss rate of the vegetables is reduced.
