Embodiment
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. determines according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in accompanying drawing 1,2,3,4, this maize harvesting machine threshing cleaning unit comprises threshing chamber frame 1, sheller unit, core seed separating cleaning device, seed cleaning conveying plant and corncob chopper, threshing chamber frame 1 is provided with the sheller unit being no less than, threshing chamber frame 1 below sheller unit is provided with core seed separating cleaning device and seed cleaning conveying plant, the discharging opening of core seed separating cleaning device communicates with the charging aperture of corncob chopper.Corn ear is entered by charging aperture, threshing is carried out by sheller unit, the corn kernel come off and corncob enter core seed separating cleaning device, core seed separating cleaning device is separated, wherein corn kernel enters seed cleaning conveying plant and carries out cleaning and being transported to tanker, and corncob enters corncob chopper by discharge gate and carries out mincing and returning to the field.The utility model is arranged on maize harvesting machine, can realize maize harvesting machine and directly gather in the crops seed, is specially adapted to self-propelled corn harvester uses, and can complete and corn ear threshing, core grain is separated, clean the work of conveying, corncob mincing and returning to the field.
according to actual needs, above-mentioned maize harvesting machine threshing cleaning unit can be made further optimization and/or improvements:
as shown in accompanying drawing 1,2,3,4, the quantity of sheller unit is one; Or the quantity of sheller unit is two and is arrange up and down.The Threshing of upper and lower two sheller units is better, can ensure enough abundant by threshing of corn.
as shown in accompanying drawing 1,2,3,4, sheller unit comprises threshing cylinder 2 and threshing concave plate 3; The outside of threshing cylinder 2 is distributed with threshing muscle or threshing tooth, threshing concave plate 3 is grid concave plate, circumferencial direction along threshing cylinder 2 is provided with one piece or two pieces of threshing concave plates 3, has and can carry out quick-adjustsing gap by governor motion between threshing concave plate 3 and threshing cylinder 2; Threshing chamber frame 1 below threshing concave plate 3 is fixed with the blade fin 4 that the corn kernel that can make to come off directly enters seed cleaning conveying plant.By the gap between governor motion adjustment threshing concave plate 3 and threshing cylinder 2, to adapt to the corn ear of different cultivars, size; The corn kernel come off in threshing concave plate 3 directly falls into the seed cleaning conveying plant of below by blade fin 4, and does not enter core seed separating cleaning device, greatly reduces the workload of core seed separating cleaning device, effectively improves separative efficiency.
embodiment one: as shown in accompanying drawing 1,2, core seed separating cleaning device comprises separating cleaning auger conveyor 5 and the separating cleaning housing 6 with sieve aperture, and it is inner that separating cleaning auger conveyor 5 is arranged on separating cleaning housing 6.Corncob and corn kernel are distally carried by separating cleaning auger conveyor 5, wherein corn kernel falls into the seed cleaning conveying plant of below in course of conveying by the sieve aperture on separating cleaning housing 6, and the separated auger conveyor 5 of cleaning of corncob pushes to discharging opening.
as shown in accompanying drawing 1,2, seed cleaning conveying plant comprises horizontal auger 8 and vertical auger conveyor 9, and the housing of horizontal auger 8 is provided with sieve aperture, and the discharging opening of horizontal auger 8 communicates with the charging aperture of vertical auger conveyor 9.Small impurities in seed can be separated from seed by the sieve aperture on horizontal auger 8 housing; Can by threshing, the seed elevator that is separated to tanker by horizontal auger 8 and vertical auger conveyor 9, transfer efficiency is lower, but the continuity of convey materials is better.
embodiment two: as shown in accompanying drawing 3,4, core seed separating cleaning device is separating cleaning travelling sieve 7.Corncob is delivered to discharging opening by shake by separating cleaning travelling sieve 7, and corn kernel falls into the seed cleaning conveying plant of below by the mesh on separating cleaning travelling sieve 7.
as shown in accompanying drawing 3,4, seed cleaning conveying plant is drag conveyer 10.By drag conveyer 10, the seed of threshing, separation is transported to tanker, transfer efficiency is higher, but the continuity of convey materials is slightly poor.
