Abstract

The utility model relates to a multi-ridge hand-operated harvester suitable to crops harvesting, belonging to the field of agricultural machines. The multi-ridge hand-operated harvester is provided with a traveling wheel. A sprocket chain drives a couple of bevel gear wheels in a gear box, and a small bevel gear wheel drives a main driving shaft to rotate. The main driving shaft is provided with two chain wheels which are respectively provided with two roots of chains connected with the chain wheels on the two roots of driving shafts on both sides. The main driving shaft and the driving shafts on both sides are both provided with circular knives. The rotation of a circular knife drives the rotation of another circular knife to generate cutting movements. The main driving shaft and the driving shafts on both sides are provided with setting wheels, and the body of the multi-ridge hand-operated harvester is provided with ridge dividers. The multi-ridge hand-operated harvester is suitable to household harvest at present.

Description

Many ridges hand reaper

The utility model belongs to agricultural mechanical field, is applicable to the harvesting of crops.

Present agricultural grain header has large-scale combine, small-sized have a hand-held grain header, and also having application number is hand reaper of 92244831.0 or the like, and kind and version are various, these grain headers all have its advantage and the scope of application, are adopted by peasants widely.But all there is certain shortcoming in these grain headers.Large-scale grain header, the present individual household of incompatibility is used, and uses though small-sized hand-held grain header is applicable on individual household or the fritter, and the price height will consume oil plant, and individual household still is unwilling to use.In addition, structurally also there is shortcoming in various degree in these grain headers.For example: number of patent application is 92244831.0 hand reaper, can only gather in a ridge culture thing, and efficient is lower, in order to enhance productivity, and the design that must make an amendment, or revise the irrational mix part.

The purpose of this utility model will design a kind of production efficiency height, hand reaper rational in infrastructure exactly.

Designer of the present utility model, on the basis of original hand reaper (number of patent application is 92244831.0), conceived a kind of many ridges hand reaper, major technique is, in gearbox by a pair of speed change bevel gear is arranged, cone pinion drives final drive shaft and rotates, on the main rotary shaft by two sprocket wheels are arranged, there is the sprocket wheel on two power transmission shafts of two chains and two sides to connect on two sprocket wheels respectively, on final drive shaft and two side power transmission shafts all by cylinder blade is arranged, because cylinder blade rotates and drives the servo-actuated cylinder blade and rotate and produced cutting movement.On final drive shaft and side power transmission shaft,, on fuselage,, reach crop arrangement vertical rod, arrangement material toggling wheel also by branch ridge device is arranged by the material toggling wheel is arranged.This design both can be provided with three power transmission shafts, again more power transmission shaft can be set.Both can drive many power transmission shafts by a chain, available again many chains drive many power transmission shafts.When a chain drives many power transmission shafts, there is the chain tension mechanism to cooperate.During with many chain drives, both can adopt the chain tension device, and can make power transmission shaft have mobile device to realize the tensioner of chain again.

The utility model is compared with other grain header, owing to can gather in many ridge culture usefulness, the production efficiency height is applicable to the use of present single household, does not need the power of electricity or engine class, and blade is advantages such as circular motion is not fragile.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the mansion view of utility model, and Fig. 2 is an end view, and Fig. 3 is the transmission schematic diagram.

Below in conjunction with Fig. 1, Fig. 2, Fig. 3 is to describe details of the present utility model and working condition in detail.

Go up by travelling wheel (4) is arranged at fuselage (1), traveling axle (2), by hinge wheel (15) is arranged, the minor sprocket (17) that chain (16), chain (16) drive on the gearbox (18) rotates on the traveling axle.Chain (16), sprocket wheel (15), (17) are covered by chain guard (3).Because minor sprocket (17) is fixed on the axle (19), large bevel gear (20) equally also is fixed on the axle (19), minor sprocket rotates large bevel gear and also rotates, because the rotation of large bevel gear, being fixed on final drive shaft (6) cone pinion (21) also rotates, be fixed on the sprocket wheel (22) on the power transmission shaft, (24) equally also rotate, because sprocket wheel (22), (24) rotation, again because chain (23) is arranged, (26) effect, driven sprocket wheel (25), (27) rotate, again because sprocket wheel (25), (27) be to be fixed on power transmission shaft (5), (7), so turning cylinder (5), (7) also rotate.Final drive shaft (6) go up and power transmission shaft (5), (7) on fixed cylinder blade (8) respectively, cylinder blade (8) rotates equally.Cylinder blade (8) but zigzag, also knife-edge.Sprocket wheel (25), (27) and chain (26), (23) are to be covered by cover (10).Go up by material toggling wheel (11) is arranged in final drive shaft (6) and power transmission shaft (5), (7).Fuselage (1) is gone up by axle (14) is arranged, on the axle again by servo-actuated cylinder blade (9) is arranged.At fuselage (1) also by branch ridge device (12) and (13) are arranged.By crop arrangement vertical rod (28) is arranged, the arrangement material toggling is tired out (29) on fuselage.Because grain header has three cylinder blades and three servo-actuated cylinder blades, harvesting efficiency increases greatly, but because people's strength is limited, and blade can not infinitely increase, therefore this harvesting is subjected to user's welcome very much.

Claims

1, by fuselage, axle, bearing, sprocket wheel, part such as bevel gear and cover, many ridges hand reaper that parts are formed, it is characterized in that: in gearbox (18) by a pair of speed change bevel gear (20) is arranged, (21), cone pinion drives final drive shaft and rotates, on the final drive shaft by two sprocket wheels (22) are arranged, (24), two chains (23) are arranged respectively on two sprocket wheels, (26) with two power transmission shaft upper sprocket wheels (25) of two sides, (27) connect, at final drive shaft (6) and two side power transmission shafts (5), (6) all by cylinder blade (8) is arranged, cylinder blade (8) rotates and drives servo-actuated cylinder blade (9) on.

2。Many ridges according to claim 1 hand reaper is characterized in that: go up in final drive shaft (6) and side power transmission shaft (5), (7) by material toggling wheel (11) is arranged, on fuselage (1) also by branch ridge device (12) and (13) are arranged.
