Abstract
A multipurpose manual harvester comprises a wheat dumping frame hopper, an upper shearing plate, a lower shearing plate, a support, a travelling wheel, a handle, a travelling wheel support and anti-skid teeth, and also comprises shifting fork assemblies respectively arranged on the travelling wheel support, wherein each shifting fork assembly consists of a first shifting fork and a second shifting fork at two ends of a shifting fork transmission shaft. The shifting fork sleeve on the shifting fork transmission shaft is connected with the travelling wheel bracket in parallel, the first shifting fork and the second shifting fork are 70 degrees, a return spring is arranged between the two second shifting forks, one end of the first shifting fork is contacted with the anti-skid teeth on the travelling wheel, and one end of the second shifting fork is arranged in the socket on the upper shearing plate.
Description
The utility model relates to a kind of hand reaper, is particularly useful for shearing through the wheat, the multipurpose hand reaper of cereal, herbage and so on.
At present, the hand reaper kind is more, substantially all is made up of cutter sweep, transmission device, the frame of advancing etc.But the complex structure of most transmission device, volume are big, the operation effort, job insecurity.The applicant's China Patent No. 94236202.0 disclosed " hand reaper " has solved the problems referred to above basically.But this machine is to drive driving lever by the waveform guide groove on the road wheel, and driving lever is from two pole inter-burst of front end mistake, because the motion frequency height, wearing and tearing are big, must apply oil during work; Shear still in work, had so also increased mechanical wear rate when this machine fell back.
The purpose of this utility model provides does not a kind ofly need apply oil in use, the idle a kind of multipurpose hand reaper of shear when falling back.
The purpose of this utility model is to realize like this, it comprises wheat-conveying frame bucket, upper shearing plate, lower shearing plate, support, left and right sides driving wheel, handgrip, left and right sides driving wheel support, anti-slop serrations on the driving wheel, also comprise and respectively adorn shifting fork assembly on the driving wheel support, first shift fork and second shift fork that shifting fork assembly is respectively established by shift fork power transmission shaft and shift fork power transmission shaft two ends are formed.The shift fork cover that disposes on the shift fork power transmission shaft is connected with the driving wheel support is parallel, and 70 ° each other of first shift fork and second shift forks are adorned return spring between two second shift forks.First shift fork, one end contacts with anti-slop serrations on the driving wheel, and second shift fork, one end places the socket on the upper shearing plate.
The utility model is because shifting fork assembly is to stir first shift fork by the anti-slop serrations on the driving wheel to teeter, making the shift fork power transmission shaft rotate 1/4th commentaries on classics drives, second shift fork promotion upper shearing plate moves reciprocatingly, wearing and tearing also are very little when high-frequency is moved, do not need in use as lubricating oil, first shift fork can also break away from the anti-slop serrations on the driving wheel when falling back, so shear is not worked, thus reduce the component wear rate near half.Also simpler, practical owing to transmission mechanism of the present utility model, not only complete machine weight saving (gross weight is ten kilograms), and improved shearing frequency, more laborsaving quick when harvesting wheat cereal crops.
Below in conjunction with accompanying drawing and example is described the technical solution of the utility model.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation that the shifting fork assembly among the utility model embodiment is installed.
With reference to Fig. 1, handgrip 10 joins with two waist joinings of support 6, and two waist ends of support 6 join with left and right bushing 9 respectively, and left and right sides driving wheel 8 is adorned at the axletree two ends in left and right bushing 9 respectively, is cast with the anti-slop serrations 14 of equi-spaced apart on driving wheel 8 foreign steamers.Its purpose not only plays anti-skidding effect.The power source of the upper shearing plate that is simultaneously.Anti-slop serrations 14 on the driving wheel of the left and right sides is not corresponding.Its mutual potential difference is 1/2nd, 1/2nd places of two anti-slop serrations 14 on promptly left (or right) driving wheel 8, and an anti-slop serrations 14 on corresponding right (or left side) driving wheel 8, shear is made up of upper shearing plate and lower shearing plate.The lower shearing plate rear portion is the front end that is fastened on left and right sides driving wheel support 15 with screw, and the rear end of left and right sides driving wheel support 15 joins with left and right bushing 9 respectively.Cut laborsaving purpose in order to play to cut, the cutting tooth and have 40 ° the basil, the cross section of last lower shearing plate to be the wasp waist 5 of shape of last lower shearing plate.Its effect is that the reinforcement shear is indeformable, and last lower shearing plate quenching hardness is up to more than 50 °, and is very wear-resisting, can not use for a long time and need repair.Compress steel disc 3 and place on the upper shearing plate, will compress steel disc 3 by connection bolt 2 and be connected with last lower shearing plate.Wheat-conveying frame bucket 1 is to make with φ 6 reinforcing bars, is connected with support 6 by bolt.With reference to Fig. 2, respectively adorn fork assembly 7 on the left and right sides driving wheel support 15, shifting fork assembly 7 is by shift fork power transmission shaft 16, first shift fork 17 of shift fork power transmission shaft 16 1 ends, second shift fork 12 of shift fork power transmission shaft 16 other ends is formed.The shift fork axle sleeve 13 and the 15 parallel connections of driving wheel support of configuration on the shift fork power transmission shaft 16.12 70 ° each other again of first shift fork 17 and second groups, dress return spring 4 between left second shift fork 12 and right second shift fork 12.First shift fork, 17 1 ends contact with the anti-slop serrations 14 of driving wheel 8, and second shift fork, 12 1 ends place the socket 11 on the upper shearing plate.Operation principle of the present utility model: when promoting handgrip, when driving wheel rotates, anti-slop serrations begins to stir first shift fork and moves downward, because the effect of circular shaft rate breaks away from anti-slop serrations after arriving certain stroke, the shift fork power transmission shaft that moves through of first shift fork drives second shift fork and promotes upper shearing plate and do transverse movement.After arriving the dead point, be installed in the shifting fork assembly on the driving wheel support 15 of relative one side, first shift fork rises to the operating position under the interlock effect of upper shearing plate.Driving wheel rotates again, and the anti-slop serrations of one side is oppressed first shift fork again relatively, drives the direction that second shift fork pushes back upper shearing plate, thereby finishes the one action stroke.Driving wheel rotates continuously, promotes upper shearing plate by shifting fork assembly and moves reciprocatingly and fixing lower shearing plate formation rubbing, reaches the purpose of shearing.
