Description

Double-spiral roller conveying and leaf removing mechanism Technical Field The utility model relates to the technical field of agricultural machinery, in particular to a double-spiral roller conveying defoliation mechanism. Background The middle part of the existing cabbage harvester is generally provided with a double-spiral roller conveying mechanism, each group of double-spiral roller conveying mechanism comprises two parallel rollers with opposite intervals and four roller brackets, the rollers are longitudinally arranged horizontally, and two ends of each roller are respectively supported on the two roller brackets in a rolling connection manner. When the cabbage is in work, the cabbage falls onto two parallel rollers which are opposite at intervals, and is conveyed by means of the principle of a screw conveyor in a backward rolling way, and the main defect of the structure is that dead leaves on the cabbage cannot fall off in the conveying process, and later the dead leaves need to be manually removed, so that the structure is labor-consuming and time-consuming. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a double-spiral roller conveying leaf removing mechanism which can basically remove dead leaves on cabbages in the conveying process and is trouble-saving and time-saving. The technical aim is achieved through the following technical scheme. The double-screw roller conveying and defoliating mechanism is arranged in the middle of the cabbage harvester, each group of double-screw roller conveying and defoliating mechanism comprises two parallel rollers and four roller brackets which are opposite at intervals, the rollers are longitudinally arranged horizontally, and two ends of each roller are respectively supported on the two roller brackets in a rolling connection mode. Further, two guard plates in a V shape are arranged above the two parallel spaced rollers, and two ends of each guard plate are fixedly connected with two roller brackets at two ends of the corresponding roller. Further, the roller bracket can be laterally adjusted in position. Further, the strip is a hard plastic pipe, and the strip (43) is embedded into a spiral groove on the outer wall of the roller (41). Further, the cabbage harvester is provided with two groups of double-screw roller conveying defoliation mechanisms which are transversely arranged at intervals in parallel. Compared with the prior art, the utility model has the following positive effects: 1. The spiral winding strip on the cylinder outer wall, rectangular fixed connection is on the cylinder outer wall, and during the use, on the cabbage dropped to two parallel interval relative cylinders, relies on auger principle, backward roll transfer transport cabbage, and simultaneously, the cylinder rotates, and the spiral winding strip is got rid of the dead leaf on the cabbage on the cylinder outer wall, like this, can get rid of the dead leaf on the cabbage basically in the transportation process, saves trouble and time. 2. The roller support can be transversely adjusted in position, and the position of the roller support can be adjusted according to the requirement so as to adjust the distance between two parallel rollers which are spaced oppositely. 3. The strip is a hard plastic pipe, and the dead leaf removing effect is good. Drawings Fig. 1 is a schematic perspective view of the present utility model from the front to the rear. Fig. 2 is a cross-sectional view of fig. 1.
