Description
Technical field
The utility model relates to agricultural machinery technological field, particularly relates to a kind of manual corn threshing device.
Background technology
In the agricultural production in modern times; what carry out threshing to corn is that big machinery carries out threshing mostly; for common peasant family; will carry out threshing as food to corn, by buying thresher, to carry out threshing be obviously unpractiaca, to by manually carrying out threshing to corn; its working time is long; intensity is large, and operating efficiency is also very low, also can cause corresponding damage to finger.And often thresher has certain destruction to iblet.
A kind of husker sheller is disclosed in prior art; comprise mounting seat, support bar, threshing outer shroud and inner ring; shake the hand and threshing unit; wherein support bar connects threshing outer shroud and mounting seat; wherein threshing unit is blade; circumferential arrangement on threshing inner annular edge, shakes the hand and is fixed on the opposite side of threshing inner ring, carries out threshing by rotating band knife section of shaking the hand to corn.But in use, blade is often along with the growth rust of service time, and blade also becomes and is difficult in the position that contacts with corncob of incision iblet, makes threshing course become difficult, to have to more allowing blade replacement again, and Renewal process is also comparatively complicated.
Summary of the invention
In view of above problem, the purpose of this utility model is to provide a kind of manual corn threshing device, not only simple operation, and long service life, with low cost.
To achieve these goals, the utility model provides following technical scheme:
A kind of manual corn threshing device, comprises handle, rolling bearing inner ring, housing washer, fixed head, and threshing unit, and described handle is fixed on the side of rolling bearing inner ring, and described threshing unit is fixed on the opposite side of rolling bearing inner ring.Described threshing unit is threshing tooth, and described housing washer is fixedly connected with fixed head.
Further, described threshing tooth is uniformly distributed along rolling bearing inner ring circumferential surface.
Further, described threshing tooth is made up of tooth root and crown, and described tooth root is a cylinder, one end is fixedly connected with rolling bearing inner ring, the described tooth root other end is fixedly connected with crown, and crown is a cone, described cone side and centrum axis shape α in an angle.
Further, described angle α is 2 ~ 8 degree.
Further, the side being positioned at the housing washer of the same side with threshing tooth is fixed with fender bracket.
Further; the truncated cone-shaped support body that described fender bracket is made up of multiple support bar and steel ring; the described steel ring center of circle and the rolling bearing center of circle are on same level line; described steel ring diameter is less than the diameter of housing washer and is greater than rolling bearing inner ring diameter; described support bar one end is fixedly connected with housing washer, and the other end is fixedly connected with steel ring.
After adopting technique scheme, manually swinging handle, drive threshing tooth to carry out threshing to corn, threshing tooth can embed in corn ear easily, leicht fallen D/A, and Threshing is good, threshing tooth can not be impaired along with the growth of service time, long service life, hardly with changing, cost is lower, is applicable to the use of general peasant family.
Accompanying drawing explanation
Below by the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is overall structure figure of the present utility model,
Fig. 2 is the schematic diagram of threshing tooth;
Fig. 3 is the schematic diagram of fender bracket.
In figure, 1 is handle, and 2 is rolling bearing inner ring, and 3 is housing washer, and 4 is threshing tooth, and 5 is fixed head, and 6 is fender bracket; 401 is crown, and 402 is tooth root; 601 is steel ring, and 602 is support bar.
Embodiment
As shown in Figure 1, the manual corn threshing device of one of the utility model design, comprise handle 1, rolling bearing inner ring 2, housing washer 3, fixed head 5, and threshing unit, described handle 1 is fixed on the side of rolling bearing inner ring 2, and described threshing unit is fixed on the opposite side of rolling bearing inner ring 2, described threshing unit is threshing tooth 4, and described housing washer 3 and fixed head 5 are by being welded and fused.Fixed head 5 is fixed on operating desk, thus whole device is fixed, then manual crank handle 1, drive threshing tooth 4 to rotate, thus can easily iblet be peeled off.Adopt threshing tooth 4, the junction of iblet and corncob can be embedded easily, and long service life, the threshing performance of this device will be caused to reduce because of friction.
Further, described threshing tooth 4 is uniformly distributed on rolling bearing inner ring 2.Equally distributed threshing tooth can make corn ear uniform force when embedding corn ear, prevents because unbalance stress causes corn ear to damage.
Be the structural map of threshing tooth as what illustrate in Fig. 2, wherein threshing tooth is made up of crown 401 and tooth root 402, and wherein tooth root 402 is a cylinder, and one end and rolling bearing inner ring are welded and fixed, and the other end and crown 401 are welded and fixed.Crown 401 is a cone, described cone side and centrum axis shape α in an angle.The size of angle α decides embedding effect and the service life of threshing tooth 4, and therefore the utility model adopts less angular range.
Further, described angle is 2 ~ 8 degree.Adopt such angular range, can better make crown 401 embed in corn ear, and wearing and tearing are less, if angle is excessive, then impact embeds effect, if angle is too small, then easily makes crown 401 rupture.It is 2 ~ 8 degree as a kind of optimized angle of the present utility model.
Further, the described side being positioned at the housing washer 3 of the same side with threshing tooth 4 is fixed with fender bracket 6.Adopt fender bracket 6, corn ear can be fixed preferably, make in threshing course, to there will not be corn rock and affect threshing course.
As shown in Figure 3, described fender bracket 6 is made up of multiple support bar 602 and steel ring 601.Described steel ring 601 center of circle and the rolling bearing center of circle are on same level line, and described support bar 602 one end and housing washer 3 are welded and fixed, and one end and steel ring 601 are welded and fixed.Steel ring 601 diameter is less than housing washer 3 diameter and is greater than the diameter of rolling bearing inner ring 2, and steel ring 601 and multiple support bar are combined to form the fender bracket 6 of a truncated cone-shaped.The fender bracket 6 of truncated cone-shaped can have good steadiness; ensure that the serviceability of whole device; the connection of support bar 602 between steel ring 601 and rolling bearing is simultaneously for tilt to connect; when carrying out threshing to corn ear; steel ring 601 can adapt to the shape of corn ear preferably; the support bar 602 simultaneously tilted can expand threshing space, makes threshing course more convenient.
