Description

A kind of reaping apparatus of cultivation by conduit romaine lettuce

Technical field

The utility model relates to a kind of parts of romaine lettuce grain header, and especially a kind of reaping apparatus of romaine lettuce grain header is applicable to the harvesting of cultivation by conduit romaine lettuce.

Background technology

Romaine lettuce is the main vegetables of European and American areas, and is nutritious, eats fresh and tender delicate fragrance raw, and have that analgesia is slept peacefully, cholesterol reducing, stimulate circulation, dietary function such as antiviral, receive very much consumer's welcome.At present; For the vegetables equipment of gathering a large amount of research has been arranged both at home and abroad; But the recovering device that with the romaine lettuce is operand is the field of research not as yet at present; Still be the domestic research that all rarely has abroad, particularly also relatively rare to the reaping apparatus of soilless culture romaine lettuce (being common in the cultivation by conduit in the greenhouse).Therefore the applicant proposes to design a kind of romaine lettuce grain header, yet how to solve the automatic cutting of romaine lettuce, becomes urgent problem.

Summary of the invention

The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of reaping apparatus of cultivation by conduit romaine lettuce is provided, and this reaping apparatus should be able to adapt to the characteristics of cultivation by conduit, can gather in romaine lettuce apace, and have easy to use, characteristic of simple structure.

For realizing above purpose, the technical scheme below the utility model has adopted:

A kind of reaping apparatus of cultivation by conduit romaine lettuce; It is characterized in that: said reaping apparatus comprises the gripper shoe of a horizontal arrangement and three cutting knifes that driven by telescopic mechanism mounted thereto; Wherein, Cutting knife and No. two cutting knifes are arranged symmetrically in the edge of gripper shoe, and No. three cutting knifes are arranged in the symmetrical centre line position of a cutting knife and No. two cutting knifes, and a cutting knife and No. two cutting knifes are shaped in opposite directions and right curved edge; The cutting edge of No. three cutting knifes stretches out towards the gripper shoe edge at a said cutting knife, No. two cutting knife places, and the movement locus of said No. three cutting knifes passed through the below of a said cutting knife and No. two cutting knifes.

In a said cutting knife and No. two cutting knifes, what offer respectively on the cutter hub of two curved edge belows that a said symmetrical center line in edge stretches crosses cutter groove, the passage of crossing said No. three cutting knifes of cutter groove amalgamation formation of crossing cutter groove and No. two cutting knifes of a cutting knife.

Said telescopic mechanism is a cylinder; Wherein No. two cylinder symmetric arrangement of a cutting knife cylinder and No. two cutting knifes, and both push rods in opposite directions and right; No. three cylinders of No. three cutting knifes, its push rod stretches towards the gripper shoe edge at a said cutting knife, No. two cutting knife places, and the flexible direction of the push rod of No. three cylinders is vertical with the flexible direction of the push rod of a said cylinder, No. two cylinders.

Be shaped on vertically baffle plate integrated on said No. three cutting knifes with it.

The operation principle of the utility model is:

Under the normality, all contractions of three cylinders; When needs are plucked romaine lettuce; Can the romaine lettuce grain header be moved to the romaine lettuce place, romaine lettuce between cutting knife and No. two cutting knifes (roughly being positioned at the symmetrical centre line position), the cylinder elongation through cutting knife of solenoid control and No. two cutting knifes afterwards; Two cutting knife move toward one another; Two curved edges can grasp romaine lettuce, and romaine lettuce is cut off in No. three cutting knife elongations afterwards; After plucking completion, three cylinders shrink, and all cutting knifes reset to carry out plucking operation next time.

The beneficial effect of the utility model is: the utility model utilizes three cutting knifes, can cut off romaine lettuce apace, the operation of can in less space, gathering; It is comparatively convenient to use; Structure is also fairly simple, can reduce labor cost greatly, but large tracts of land is promoted the use of.

Embodiment

Below in conjunction with Figure of description, the utility model is described further, but the utility model is not limited to following examples.

As shown in the figure, the reaping apparatus of the described a kind of cultivation by conduit romaine lettuce of the utility model comprises the gripper shoe 1 of a horizontal arrangement and three cutting knifes that driven by telescopic mechanism mounted thereto, and three is flexible the equal along continuous straight runs of cutting knife.

Described telescopic mechanism is a cylinder; Wherein cylinder 8 and No. two cylinders 4 are arranged symmetrically in the edge of gripper shoe; And both push rods in opposite directions and right; The end of a push rod and No. two push rods is being fixed cutting knife 7, No. two cutting knifes 5 (employing bolt) respectively, and an obvious cutting knife and No. two cutting knifes are in opposite directions and to (and the cutter hub of a cutting knife and No. two cutting knifes all be positioned at gripper shoe outer).No. three cylinder is fixed on the plate face of gripper shoe; Be positioned at the symmetrical centre line position of a cutting knife and No. two cutting knifes; Its push rod stretches (flexible direction is perpendicular to the flexible direction of the push rod of No. one, No. two cylinder) towards the gripper shoe edge at a cylinder and No. two cylinder places; No. three cutting knifes 6 (employing bolt) are being fixed in the end of No. three cylinders 3, and No. three cutting knifes are flat cutting knife, and its cutting edge 6-1 stretches out the gripper shoe edge at a said cutting knife, No. two cutting knife places.Be convenient cutting, one-body molded on said No. three cutting knifes have a baffle plate 6-2 who vertically arranges to draw romaine lettuce in.

A said cutting knife and No. two cutting knifes are shaped in opposite directions and right curved edge 7-1 (radius is confirmed according to actual conditions); Respectively offer the 7-3 of cutter groove excessively that a said symmetrical center line in edge stretches on the cutter hub of two curved edge belows; The passage of crossing said No. three cutting knifes of cutter groove amalgamation formation of crossing cutter groove and No. two cutting knifes of a cutting knife (width and the degree of depth of crossing the cutter groove are confirmed according to No. three cutting knifes); The movement locus of said No. three cutting knifes passed through this passage, and romaine lettuce is cut off.

The equal buyable of described cylinder obtains.Also has mounting groove 7-2 among the figure.
