Embodiment
Illustrate below in conjunction with accompanying drawing and with embodiment, the utility model to be further illustrated.
A kind of cylinder installed threshing separator integrated with concave grate, as shown in Figure 1, comprise threshing cylinder body 1, sub-concave grate 2, demarcation strip 3 and impeller 4, as shown in Figure 2 and Figure 4, described threshing cylinder body 1 is made up of tooth plate 1-3, connection bracket 1-2 and power transmission shaft 1-1, described tooth plate 1-3 is connected by connection bracket 1-2 with power transmission shaft 1-1, preferably, with bolts between tooth plate 1-3 and power transmission shaft 1-1, with bolts between described tooth plate 1-3 and described connection bracket 1-2, facilitate the dismounting of device and the replacing of tooth plate.Described tooth plate 1-3 quantity is preferably 4 ~ 8, can change according to actual needs, the overall circular arrangement of tooth plate 1-3, and as shown in Figure 5, on tooth plate 1-3, threshing element is spike-tooth 1-4; Spike-tooth 1-4 all points to power transmission shaft 1-1, and making formed cylinder depart from mode is Neto form, and namely carry out threshing at drums inside, namely material departs from the inside of cylinder, but not carries out threshing along cylinder outer wall as traditional sheller unit.Relatively traditional cylinder, the de-separating device of interior de-form can not only reduce the volume of device, and can increase threshing area, in identical feed quantity situation, lower power consumption.On tooth plate, spike-tooth quantity is 15 ~ 20, can suitably change within the scope of this as required, in feeding one end of cylinder, not de-material ratio is more, therefore, on threshing tooth plate, the distribution of threshing element spike-tooth is relatively intensive, the not de-material of the contrary cylinder other end is less, and on threshing tooth plate, the distribution of threshing element spike-tooth is relatively sparse, is conducive on the one hand reducing blocking, improve threshing efficiency, can also energy consumption be reduced on the other hand; As shown in Figure 3, sub-concave grate 2 is provided with between described two often adjacent tooth plate 1-3.Described sub-concave grate 2 is punched holes type, form cabinet-type between each cross-talk concave grate 2 with each tooth plate 1-3 to be connected, namely a tooth plate 1-3 is connected between two sub-concave grates 2, connect a sub-concave grate 2 between two tooth plate 1-3, all sub-concave grates 2 surround a circular and closed installed threshing separator jointly with all tooth plate 1-3.Sub-concave grate 2 is connected with bolt with between tooth plate 1-3, thus sub-concave grate 2 is rotated along with the rotation of threshing cylinder, each sub-concave grate 2 in de-point process all can be separated, further increase the separating area of sub-concave grate 2.Described demarcation strip 3 is arranged on the position of distance threshing cylinder exit certain distance, this distance can be changed as required, its short cane being mainly used in separating disengaging from threshing cylinder and going out, prevent the rotation of short cane to impeller 4 from having an impact, demarcation strip 3 size and threshing cylinder export size one to, demarcation strip 3 has a lot of aperture, and the air-flow of the formation that impeller 3 is rotated can by demarcation strip 3.After described impeller 4 is arranged on demarcation strip, as shown in Figure 6, the present embodiment impeller 4 is made up of four blades, key is adopted to be connected between impeller 4 with power transmission shaft 1, rotate along with the rotation of power transmission shaft 1, in the process of rotating, form absorption type air-flow simultaneously, thus drive material and short cane to move to exit from the porch of threshing cylinder, reduce the blocking of de-separating device inside.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the personnel of the utility model art, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
