Embodiment Construction
[0013] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0014] As shown in the accompanying drawings, a stone removal machine observation door structure includes a feed channel 1 and a trapezoidal table-shaped suction hood 2 communicating with the bottom of the feed channel 1. Trapezoidal viewing port 3, two spring hinge hinges 5 are installed above the viewing port 3, and a transparent viewing door 4 compatible with the viewing port is installed on the two spring hinge hinges 5; the left and right sides of the viewing port 3 and Both sides below are fixed with the connecting rod 7 connected by the rotating shaft 9, and the pressing block 8 of elastic rubber is fixed at the end of the connecting rod 7; There is a seal 11 with a triangular silica gel material in cross section.
[0015] In the structure of the observation door of the stone removal machine, during normal operation, the observation door 4 is buc...

The invention discloses a stoning machine observation door structure, and belongs to the field of grain machine cleaning. The stoning machine observation door structure comprises a feeding channel anda trapezoid-table-shaped air suction hood communicating with the lower portion of the feeding channel. Trapezoid observation ports are formed in the four side faces of the air suction hood. An adaptive transparent observation door is arranged on each observation port through two hinges. Connecting rods are connected to the left side and the right side of each observation port and the two sides ofthe lower portion of each observation port through rotation shafts. Pressing blocks are fixed to the end portions of the connecting rods. Step bosses are arranged at the edge positions of the observation ports, and sealing strips with the triangular cross sections are fixed to the outer sides of the bosses. Observation, opening and closing are convenient and fast, the observation doors can be opened at any time, hemp ropes and other impurities and mud left on an upper-layer screen are removed, the structures of the sealing strips are not damaged, and cleaning rapidness and convenience can beguaranteed; the sealing performance is good, and the problem that due to untight sealing, the separation effect is not ideal is eradicated; and the repairing cost is low, and the production efficiencyis high.
Description
technical field [0001] The invention belongs to the field of grain mechanical cleaning equipment, and in particular relates to a stone removal machine observation door structure. Background technique [0002] According to the specific gravity and suspension speed of sand and rice, the de-stoner machine uses the inclined screen surface with certain motion characteristics and the wind force passing through the fish scale holes on the screen surface to separate the grain stone (suction type de-stoner machine also needs a larger air volume) device. When the material flows from the feed hopper to the middle section of the screen surface, it is immediately affected by the combined effect of the inclined airflow from top to bottom and the mechanical movement of the screen surface, so that the sand with higher density will sink to the lower layer of the material and the screen surface after being automatically classified. Contact; the rice with less density and rougher surface is i...
