Soil sieving mechanism used on crop harvesting device

Abstract

The invention discloses a soil sieving mechanism used on a crop harvesting device, and belongs to the field of agricultural machinery devices. The soil sieving mechanism used in the crop harvesting device is used for removing soil attached to crops. According to the soil sieving mechanism, stirring parts are arranged in a sieving barrel (1) and provided with multiple spiral blades (3); the spiral blades (3) are divided into a left set and a right set, the rotation direction of the left set of the spiral blades (3) is opposite to that of right set of the spiral blades (3), and the spiral blades (3) are provided with multiple rubber columns; feeding holes (4) and a discharging hole (5) are formed in the sieving barrel (1); the discharging hole (5) is formed in the middle of the back face of the sieving barrel (1). After the harvested crops enter the soil sieving mechanism from the feeding holes, the stirring parts drive the crops to rotate and turn over together, the rubber columns simulate fingers to remove the soil, the soil removing effect is good, the crops are not damaged, and the crops roll to the sieving barrel (1) from the two ends and are discharged from the discharging hole (5).

Description

technical field [0001] The invention relates to a soil sieving mechanism, in particular to a soil sieving mechanism used on a crop harvesting device, and belongs to the field of agricultural technology and agricultural machinery. Background technique [0002] The edible parts of many crops grow underground, such as potatoes, peanuts, garlic, etc. When using mechanized devices to harvest these crops, it is necessary to use a coulter to plow the harvest from the ground, and it is inevitable that the soil and the harvest will stick together. In the prior art, the general method of soil removal is to use a simple rolling sieve or a shaking sieve to remove the soil on the crops, and the soil removal effect is very poor; there are attempts to use a vibrating sieve or other methods, because the skin of potatoes, garlic, etc. is very Fragile, it is easy to cause damage to crops, affecting crop yield and quality. Contents of the invention [0003] The object of the present inventi...
