researched the use of vibration for soil removal in the Panax notoginseng harvesting process and analyzed the influence of elevator speed, vibration frequency of the vibrating screen sieve, speed of rototiller parameter on root damage rate, and harvesting net rate. Peanut fruit, seedlings, and soil are thrown up and the soil removed under the vibration of the screen. studied the transportation and separation process in peanut harvesting. separated potatoes and soil with the cooperation of a vibration device and a screen, and the influence of vibration parameters on the separation performance was analyzed. , for example, analyzed the law of straw vibration for soil removal by removing the adhering soil and mixing it with yellow corn silage straw. Regarding research on crop separation techniques, Fu et al. Vibration technology is widely applied in the agricultural machinery equipment design and manufacturing process, as it can not only destroy the soil structure to separate crops from soil efficiently, but also reduce the power consumption of the machine as a whole, thus reducing the cost of operation.

Therefore, the key issue is how to ensure the efficient separation of tiger nuts from sandy soil while reducing the power consumption of the machine as a whole, carrying out a combined conveyance and separation process. There is no ideal technical solution to reduce power consumption. Currently, tiger nuts are widely planted in sandy soil in south Xinjiang, and the harvesting method is to dig a mixture of sand soil and tiger nuts together. The main power consumption in the mechanized harvesting of tiger nuts comes from the process of digging, conveying, and separation. The Shaoyang Agricultural Machinery Research Institute have developed a tiger nut harvester that adopts a spiral screening machine, a reciprocating vibrating screen, and other schemes to complete soil separation. adopted the structure of post-vibration two-stage separation to separate the mixture of tiger nut, root, and sandy soil.

and Beijing Changxin Agricultural Technology Co., Ltd. Xinxiang Dilong Pharmaceutical Machinery Co., Ltd. Through the rotating double-layer drum screen and the grid bar screen body swinging in a reciprocating arc, the pellet-shaped straw sundries are released to separate the tiger nut. has designed a double-layer drum-type tiger nut harvester. Harbin Dongyu Agricultural Engineering Machinery Co., Ltd. optimized the parameters of a caterpillar self-propelled tiger nut harvester hoisting device, studying the influence of vibration frequency, amplitude, and other parameters on the soil-sieving rate. In terms of research on the mechanized harvesting technology of tiger nuts, an earlier harvester in Spain was mainly comprised of a digging shovel, vibrating screen, walking wheel, and transmission device, and its overall design principle is still used today. The results showed that the conveying and soil-removing device could meet tiger nut harvest performance requirements. The tiger nut damage rate was 1.16%, and the leakage rate was 0.52%. The field test determined that the relative errors of conveyance efficiency and sandy soil removal rate with theoretical values were 2.55% and 1.41%, respectively. The test results showed that the optimal parameter combination was a spiral speed of 107 r/min, a vibration amplitude of 8.5 mm, and a vibration frequency of 10.7 Hz, under which the theoretical value of conveyance efficiency was 80.39%, the sandy soil removal rate was 84.61%, and the variation coefficient of sandy soil removal velocity was 3.6%. The simulation testing was carried out using spiral speed, vibration amplitude, and vibration frequency as the independent variables and conveyance efficiency, sandy soil removal rate, etc., as the dependent variables. The results showed that the vibrating force was more conducive to the complete removal of sandy soil and the effective conveyance of tiger nuts. The device was numerically simulated with and without vibration using EDEM software. Aimed at solving the large power consumption and high operating cost problems associated with the process of harvesting tiger nuts, the use of a conveying and soil-removing device which removes sandy soil while conveying tiger nuts was proposed.
