“…Sunflower harvesting is performed with specific headers (Figure 1) that are designed for collecting sunflower seeds and transporting them to the inclined chamber of the combine harvester. Sunflower headers generally consist of the frame, auger, seed conveyors, choppers stems, dividers, and cutting units [34]; suitable combine settings for sunflower are given in Table 2. The use of sunflower headers is generally associated with values of seed loss of 2% [34], if considering the average global yield for sunflower in 2018 of 1.97 Mg ha −1 [73], which corresponds, approximately, to 39 kg ha −1 of lost seed.…”

Herbaceous Oil Crops, a Review on Mechanical Harvesting State of the Art

2020

The sustainable production of renewable energy is a key topic on the European community’s agenda in the next decades. The use of residuals from agriculture could not be enough to meet the growing demand for energy, and the contribution of vegetable oil to biodiesel production may be important. Moreover, vegetable oil can surrogate petroleum products in many cases, as in cosmetics, biopolymers, or lubricants production. However, the cultivation of oil crops for the mere production of industrial oil would arise concerns on competition for land use between food and non-food crops. Additionally, the economic sustainability is not always guaranteed, since the mechanical harvesting, in some cases, is still far from acceptable. Therefore, it is difficult to plan the future strategy on bioproducts production from oil crops if the actual feasibility to harvest the seeds is still almost unknown. With the present review, the authors aim to provide a comprehensive overview on the state of the art of mechanical harvesting in seven herbaceous oil crops, namely: sunflower (Heliantus annuus L.), canola (Brassica napus L.), cardoon (Cynara cardunculus L.), camelina (Camelina sativa (L.) Crantz), safflower (Carthamus tinctorius L.), crambe (Crambe abyssinica R. E. Fr.), and castor bean (Ricinus communis L.). The review underlines that the mechanical harvesting of sunflower, canola and cardoon seeds is performed relying on specific devices that perform effectively with a minimum seed loss. Crambe and safflower seeds can be harvested through a combine harvester equipped with a header for cereals. On the other hand, camelina and castor crops still lack the reliable implementation on combine harvesters. Some attempts have been performed to harvest camelina and castor while using a cereal header and a maize header, respectively, but the actual effectiveness of both strategies is still unknown.

The object of research is the seed material and working bodies of a vibro-pneumatic centrifugal separator; the subject is their interaction. The established surfaces, which are the results of the simulation of the process of separation of seed materials in the vibro-pneumatic centrifugal separator, have a curve to the plane whose parameters are the speed of the air flow and the frequency of oscillations of the working surface. It is noted that this nature of the dependence of the purity of the «heavy» fraction of seeds on parameters of the separation process makes it possible to determine the rational ranges of these parameters, at which the maximum value of this characteristic is reached. Experimental simulation of the separation process in the vibro-pneumatic centrifugal separator of wheat, sunflower, and soybean seed materials under production conditions showed a high convergence of the results with the results of the simulation of the process under the same initial conditions. It was established that the correlation coefficients between the points obtained experimentally and obtained by simulation for the given results are in the range from 0.89 to 0.95. At the same time, the differences are the purity values of the «heavy» seed fraction, and not in the nature of its change due to changes in the parameters of the separation process. The expediency of using modeling when determining the rational values of the parameters of the separation process in the vibro-pneumatic centrifugal separator is noted. This will help increase the energy and resource efficiency of the equipment due to the absence of the need for experimental setup. The rational ranges of air flow speed and vibration frequency of the rotor of the vibro-pneumatic centrifugal separator for the separation of seed materials have been determined: wheat – 1.2...1.5 m/s; 4500...5100 cycles per minute; sunflower – 1.3...1.5 m/s; 4500...5000 cycles per minute; soybeans – 1.3...1.6 m/s; 5000...5500 cycles per minute

In view of the low degree of mechanization and poor quality of harvesting of edible sunflower after drying, an in situ bionic harvesting device was designed, which can achieve low-loss harvesting of edible sunflower without removing the edible sunflower disc. According to the physical characteristics of sunflower stalks in the field, influencing factors of in situ low-loss feeding were obtained, and the structural parameters of the in situ feeding mechanism were determined. Based on bionic technology and static analysis, the influencing factors on the performance of the bionic threshing mechanism were obtained. By analyzing the mechanical characteristics of edible sunflower seed, the operation parameters of the seed collection mechanism were determined. Based on the structural analysis results of the harvesting device, a response surface optimization test was carried out. The test results show that when the average rotation speed of the bionic loosening roller was 113.57 rpm, the average rotation speed of the simulated artificial striking roller was 230.80 rpm, the average forward speed of the harvesting device was 0.58 m/s, the working quality of the harvesting device was the best, the seed loss rate was 2.12%, and the edible sunflower disc threshing rate was 98.96%. A field verification test further confirms that under the optimal working parameters, the relative deviation between test indexes and response surface optimization test results was less than 2%. During the operation process, the movement of key components of the harvesting device was coordinated and stable. The research results can provide new ideas for the mechanized harvesting of the edible sunflower disc after drying.
