Description
Technical field
The utility model relates to a kind of green vegetables grain header, especially a kind of reciprocal reaping apparatus of crank rocker compressed spring type for leaf vegetables results.
Background technology
Along with the development of agricultural modernization technology, vegetables mechanized harvest technology more and more comes into one's own in China.Especially leaf vegetables mechanized harvest technology, is domesticly still in the starting stage.Due to artificial harvested vegetable inefficiency, and along with the aggravation of China's aging population, the quantity of labour force declines greatly; The harvesting of leaf vegetables is also gradually by manually changing to mechanization.But also do not release the reciprocating grain header of harvesting leafy green vegetable in the market, reason there is no applicable reaping apparatus.
Utility model content
Technical problem to be solved in the utility model is the deficiency overcoming above-mentioned background technology, a kind of reciprocal reaping apparatus of crank rocker compressed spring type that can gather in leaf vegetables is provided, this device should be able to be arranged on leaf vegetables grain header and work, and has that harvesting efficiency is high, structure is simple, lower-cost feature.
The technical solution adopted in the utility model is as follows:
The reciprocating reaping apparatus of crank rocker with spring pre-tightening, is characterized in that: this device comprises the horizontally disposed saw blade for cutting leaf vegetables, back and forth drives the cutting power assembly of saw blade and coordinate with cutting power assembly and realize the reciprocating spring assembly of saw blade;
Described cutting power assembly comprises a crank and rocker mechanism and this crank and rocker mechanism is provided to the motor of power, and the rocking bar of crank and rocker mechanism and one end of described saw blade are articulated and connected.
In described crank and rocker mechanism, be all rotatably positioned in frame as the porose gear of crank and rocking bar, the two ends of connecting rod respectively with porose gear and rocking bar hinged; Motor is by the gear drive crank and rocker mechanism with porose gears meshing.
In described spring assembly, fork is hinged in frame rotationally, and one end of fork and the other end of described saw blade are articulated and connected, and the other end of fork is then fixed on frame spring with one is connected.
Described cutting power assembly and spring assembly are separately positioned on the both sides of frame.
The two ends of described spring are fixed on frame and rocking bar respectively by drag hook.
Operation principle of the present utility model is: during work, electric motor starting is rotated by the porose gear of gear driven (crank), connecting rod drives again rocking bar reciprocally swinging, makes horizontally disposed saw blade carry out bilateral reciprocation (being similar to linear reciprocating motion); The reciprocating motion of saw blade cause the fork reciprocally swinging of the saw blade other end, spring namely to stretch or contractile motion to coordinate saw blade motion; Finally make saw blade make horizontal reciprocating movement, carry out the cutting of vegetables.
The beneficial effects of the utility model are: this device can be arranged on the front end of leaf vegetables grain header, and the serrated face of saw blade forward, can gather in vegetables such as the leaf vegetables in field; Not only harvesting efficiency increases substantially than hand harvest, and simple and practical, manufacture easy to maintenance, thus cost is lower; Be applicable to applying.

Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail, but the utility model is not limited to following examples.
The reciprocating reaping apparatus of crank rocker of the band spring pre-tightening shown in Fig. 1, comprise the cutting power assembly 1 being fixed on frame side (side of left and right directions), be fixed on the spring assembly 2 of frame opposite side, and the saw blade 3 that two ends are connected with cutting power assembly, spring assembly respectively, blade level is arranged, sawtooth is (the grain header direction of motion) toward the front.
In cutting power assembly shown in Fig. 2: motor support plate 1-6 and frame affixed with fixing cutting power assembly; Motor support plate has two through hole, and motor 1-1 (preferred reducing motor) is fixed in motor support plate, and the rotating shaft bottom of motor is down through after macropore, and gear 1-5 is fixed in this rotating shaft again.Gear shaft 1-2 is positioned at (bearing holder (housing, cover) is fixed by screws in motor support plate) on motor support plate 1-6 by bearing holder (housing, cover) 1-3, the bottom of gear shaft down pass through aperture and extend to motor support plate below after, in crank and rocker mechanism, (one in crank rocker) to be fixed on this axle (bottom that in Fig. 2, Fig. 3, this porose gear known to be fixed on gear shaft by key and nut) as the porose gear 1-4-1 of crank again.Motor is by this porose gear of gear drive fixing in its rotating shaft.
In crank and rocker mechanism shown in Fig. 3, porose gear 1-4-1 has a hinge hole, hinged by one end (being right-hand member in figure) of gear hinge axis 1-4-2 and connecting rod 1-4-3, the other end (being left end in figure) of connecting rod is hinged with one end (being front end in figure) of rocking bar 1-4-5; Also have hinge hole in the middle part of rocking bar, be positioned at (side of fixed mount is fixed in frame) on fixed mount 1-4-4 by jointed shaft (hinge axes 1-4-41) is hinged rotationally, rocking bar 1-4-5 can be swung by projected route.Then be connected with saw blade 3 the rocking bar 1-4-5 other end (being rear end in figure) (being normally articulated and connected).
In spring assembly shown in Fig. 4: affixed with frame on the left of fixed block 2-7, opposite side fixes a fixed block drag hook 2-6.Flap 2-1 is fixed in frame, and two that take the shape of the letter U upper lower cantalevers all have hinge hole, and hinge-rod axle 2-2 vertically down interts and is articulated with in two hinge holes; The bottom of hinge-rod axle is also interspersed in the through hole in the middle part of fork 2-3 and is fixed by nut and fork, and fork is rotatably positioned on flap.One end and the saw blade 3 of fork are hinged and connected, and the other end also fixes a fork drag hook 2-4, and the two ends of spring respectively hooking are connected on this fork drag hook and fixed block drag hook.
Operation principle of the present utility model is as shown in Fig. 5-Fig. 7: electric motor starting during work, and drive porose gear 1-4-1 (crank) to rotate by gear 1-5, thus order about rocking bar 1-4-5 reciprocally swinging by connecting rod, namely saw blade 3 produces bilateral reciprocation; The reciprocating motion of the saw blade other end, makes again fork 2-3 around hinge axes (i.e. hinge-rod axle 2-2 axis) reciprocally swinging.When rocking bar forward swings, saw blade moves right under rocking bar pulls, and spring is stretched and puts aside potential energy (Fig. 5 is the extreme position after saw blade moves right, spring be stretched maximum rating); During rocking bar backswing, the release of potential energy that spring gathers, pulls saw blade 3 to left movement (Fig. 7 is saw blade post exercise extreme position left, spring be stretched minimum state), thus supports that saw blade completes reciprocating motion; So repeatedly, finally make saw blade make horizontal reciprocating movement, obtain the motion state needed for Cut vegetables.
Show in Fig. 8: the utility model is arranged on the front side of leaf vegetables grain header.
