Problems solved by technology

[0003] Most of the existing oily bean harvesters are slightly modified on the basis of peanut harvesters. No special threshing and cleaning device has been studied, and no threshing device has been installed. Most of them use traditional roller screen or flat vibrator. The sieve separation device generally has the problems of large harvest loss, low cleanliness, easy winding and clogging
Especially poor adaptability and high requirements for working conditions: (1) For vibrating screens with high moisture, especially when the roots are green, the grains, soil, and roots stick together. It is difficult to separate during the screening process, and the materials will be tightly sticky. Attached to the sieve surface, causing congestion or being forced to shut down, reducing the efficiency of harvesting; the sieved grains have more impurities and are prone to mildew in storage; and the vibrating screen consumes high energy, is noisy, and is easily damaged, requiring regular inspections. Maintenance and maintenance increase the cost of use
(2) The volume and weight of the drum sieve are large, which has a great influence on the layout and stable use of the machine; the mesh size of the screen is fixed, and the unfulfilled grains are easy to be screened out along with the impurities; the work efficiency is low, and when there are many materials, the screen mesh Blockage, if the screening is not timely, the grains will be discharged together with the rhizomes, resulting in low removal rate and high entrainment loss rate, which seriously affects the screening effect

Abstract

The invention discloses a cyperus esculentus harvest threshing, separating and cleaning system, and belongs to the technical field of agricultural machinery. The system comprises a frame, a threshingcylinder, a straw shaker, a cleaning fan and a transverse conveyor, the threshing cylinder is arranged at the end of one side of the frame through bolts, and the threshing cylinder comprises a threshing shaft component, an upper cover arc plate and a lower screen arc plate. The upper cover arc plate and the lower screen arc plate are fixedly connected through bolts to form a cylindrical structure,a feeding port is formed at one end, a discharging port is formed at the other end, and the threshing shaft component is arranged in the cylindrical structure. The whole set of threshing and cleaningsystem has good separability, liquidity and multiple cleaning functions through working components such as the tangential flow type threshing cylinder, a double-layer multi-stage four-box type strawshaker separation device, the cleaning fan and the transverse conveyor with the soil leakage function; and faults and problems such as winding of rhizomes, blocking of a screen and incomplete separation can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a threshing, separation and cleaning system for a combined harvester of oily sage beans. Background technique [0002] Oil-sand bean, also known as underground walnut, is one of the more promising new oil crops in the plant world, but it cannot be widely planted because of the difficulty of mechanized harvesting. The main problem existing in the mechanized harvesting of the oily bean is the difficulty of separating and cleaning the harvested material. The reason is that the grain of the oily bean is firmly connected with the rhizome and is bound in the soil below the surface. The method of digging must be used when harvesting. There are also various impurities such as soil and rhizomes outside the grains. During mechanized harvesting operations, it is necessary to ensure that the grains can be separated from the rhizomes, and to achieve effective separ...
