Description

Technical Field

[0001] This invention belongs to the field of vegetable loss-mitigation harvesting technology, specifically a low-loss threshing and cleaning device for highland barley and its usage method. Background Technology

[0002] Barley is an annual herbaceous plant with erect, smooth stems. The leaf sheaths are smooth, mostly shorter than the internodes, or at least longer than the internodes at the basal end, with auricles on both sides of the apex that clasp the stem; the ligule is membranous, and the leaf blades are slightly rough. The spike-like inflorescence turns yellowish-brown or purplish-brown when mature; the spikelets have linear-lanceolate glumes covered with short hairs, and the apex is acuminate and awn-like. The lemma extends to an awn at the apex and has fine bristles on both sides. The caryopsis easily detaches from the lemma when mature. It is commonly cultivated in the northwestern and southwestern provinces of China. It thrives in cool, high-altitude climates. It is highly cold-hardy, has a short growing season, is high-yielding, early-maturing, and widely adaptable.

[0022] like Figure 1-12 As shown, this invention provides a low-loss threshing and cleaning device for highland barley, including a frame 1. A motion mechanism is provided at the lower part of the frame 1 to drive the frame 1. A low-loss threshing mechanism is provided on the frame 1 for low-loss threshing of barley. A conveying mechanism is connected to the front end of the low-loss threshing mechanism for conveying the fed barley. A harvesting mechanism is connected to the front side of the conveying mechanism for harvesting the barley. A feeding mechanism is connected to the harvesting mechanism for feeding the barley. A cleaning mechanism is provided on the frame 1 for cleaning the threshed barley grains. An output mechanism is connected to the rear side of the low-loss threshing mechanism for outputting the threshed barley straw. A collecting mechanism is connected to the frame 1 for collecting the threshed barley grains.

[0023] Advantageously, the low-loss threshing mechanism includes a threshing box 7 mounted on the frame 1. The threshing box 7 consists of a front section, a middle section, and a rear section. A threshing shaft 92 is rotatably connected through each of the three sections. A threshing pulley 8 is fixedly mounted on one end of the threshing shaft 92. A threshing belt 9 is wound around the pulleys 8. A front rotating drum 74 is fixedly mounted on the outer surface of the threshing shaft 92 in the front section. A middle rotating drum 72 is fixedly mounted on the outer surface of the threshing shaft 92 in the middle section. The threshing shaft 92 in the rear section... A smooth roller 69 is fixedly installed on the outer surface. An extrusion shaft 87 is rotatably connected inside the front-end rotating drum 74. The extrusion shaft 87 is powered by a primary release motor fixedly installed inside the front-end rotating drum 74. A plum blossom column 86 is fixedly installed on the outer surface of the extrusion shaft 87. The plum blossom column 86 pushes several rows of conical sliding rods 89 to move. Several rows of conical sliding rods 89 are arranged in a circumferential array on the front-end rotating drum 74. The conical sliding rods 89 are slidably connected to the front-end rotating drum 74. A drive mechanism is sleeved on the surface of the conical sliding rods 89. The cone-shaped slide bar 89 is reset by a compression spring 90. A compression plate 75 is fixedly connected to the end of the cone-shaped slide bar 89. Several short spiral-patterned rubber nail teeth 91 are installed on the outer surface of the compression plate 75. Several long spiral-patterned rubber nail teeth 99 are fixedly installed on the outer surface of the front-end rotating drum 74 between adjacent compression plates 75. A filter concave plate 53 is slidably connected inside the frame 1 below the threshing box 7. Fixing blocks 57 are symmetrically arranged on the end wall of the frame 1. One end of a concave plate adjusting electric push rod 56 is connected to the upper side of the fixing block 57. The filter concave plate 53 is connected to the other end of the rod 56. Elastic columns 73 are uniformly fixedly installed on the upper side of the filter concave plate 53 and inside the front part of the threshing box 7. Several flexible steel wire brushes 71 are uniformly fixedly connected to the outer surface of the middle section of the rotating drum 72. The flexible steel wire brushes 71 are arranged in a circumferential array. Several short nail teeth 70 are uniformly fixedly installed on the upper side of the filter concave plate 53 and inside the middle section of the threshing box 7. The other end of the threshing rotating shaft 92 on the front side is poweredly connected to the threshing motor 54 fixedly installed on the outer surface of the threshing box 7. The diameters of the three sections are different. During operation, the threshing motor 54 is started, which drives the threshing shaft 92 to rotate, thereby driving the threshing pulleys 8 to rotate, which in turn drives the threshing belt 9 to rotate. This causes all the threshing pulleys 8 to rotate, which in turn drives the threshing shaft 92 to rotate, thereby driving the front drum 74 to rotate. Simultaneously, the initial threshing motor is started, which drives the extrusion shaft 87 to rotate, thereby driving the plum blossom column 86 to rotate. This pushes the conical slide bar 89 to move, causing the extrusion spring 90 to be in a compressed and relaxed state. This causes the extrusion plate 75 to rotate, which in turn drives the short spiral rubber nail teeth 91 to rotate. The short spiral rubber nail teeth 91 rotate and reciprocate, creating pressure between the short spiral rubber nail teeth 91 and the elastic column 73, thus achieving threshing. The rubber spikes 99 and the elastic column 73 cooperate to achieve threshing without damaging the barley grains. The barley threshed at the front end enters the middle section. When the threshing shaft 92 rotates, it drives the middle section drum 72 to rotate, which in turn drives the flexible steel wire brush 71 to rotate. The brush cooperates with the short spikes 70 to thresh the barley and prevents the grains from sticking together. When the threshing shaft 92 rotates, it drives the smooth roller 69 to rotate. The inertia of the smooth roller 69 is used to thresh the barley again, avoiding excessive impact. The threshed barley grains fall onto the corrugated stainless steel screen 61 through the filter concave plate 53. Based on the damage of the barley grains, the electric push rod 56 of the concave plate is energized to adjust the position of the filter concave plate 53, reducing the breakage rate during threshing.

The incomplete gear 102 meshes with the rack 103, thereby driving the moving blade 55 to move. When the incomplete gear 102 meshes with different racks 103, the moving blade 55 moves in different directions, thus driving the moving blade 55 to reciprocate. The moving blade 55 cooperates with the fixed blade 26 to cut, thereby harvesting the barley.
