“…These results indicate that the cleanliness level of threshed sorghum seeds is significantly affected by the initial moisture content of seeds. This is in line with study conducted by Gawłowski et al (2020), where the moisture of seeds more influences the process of impact crushing than the change of the rotational speed of the thresher. At a lower moisture content, sorghum seeds tend to produce a higher level of seed cleanliness at high and low threshing clamp rotational speeds.…”

Sorghum is a plant with broad adaptability, is resistant to drought, and is very suitable in marginal areas. Sorghum plants contain 7% to 17% seed composition and 83% to 93% leaf stems. At harvest, the moisture content of seeds is 20% to 30%, and the stem is around 76% to 88%. Several stages are carried out after the sorghum harvesting process, and one of them is threshing the sorghum seeds. The threshing of sorghum seeds requires a hold-on threshing machine so seeds can be threshed immediately after harvest, and the stems from sorghum plants can be chopped directly for cattle feed. This study aims to design and test the performance of a hold-on type sorghum threshing machine that can be used to thresh sorghum seeds immediately after harvesting at a grain moisture content of around 20% to 30%. The methods used include problem considerations, the preparation of structural designs, functional designs, manufacturing drawing designs, and manufacturing functional and performance testing. The results of testing the performance of the threshing machine revealed that the working capacity of the machine was affected by rod clamp rotation, the threshing cylinder, and the moisture content of sorghum seeds. The cleanliness level of sorghum seeds is above 90%, while the level of seed damage ranges from 0% to 1%.

For harvesting crops, one-phase and two-phase methods are most often used. When implementing the second one, mounted and trailed units are used. The latter is becoming less and less used due to the problems with movement stability in the horizontal plane because of the asymmetric layout. A stubble background, which is susceptible to solar and wind influences, is formed as a consequence of application of the mounted harvesting unit, As a result, the field’s soil in the inter-swath space intensively loses moisture. A harvesting unit based on a tractor with rear steerable wheels has been designed to eliminate this shortcoming. A header is mounted on its front hitch linkage system, and a disc harrow is mounted on the rear one. During the working movement, such a harvesting unit mows the crop into swaths, chops the stubble in the inter-swath space, and simultaneously incorporates it into the soil. This article presents the operation results of such a unit for harvesting winter wheat, oats, and sudan grass. Research has established that oscillations in the deviations of the mowed crops’ swaths from a straight line are of low frequency. The variances spectra of this process, as follows from the Analysis of normalized spectral densities, are concentrated in the frequency range of 0-0.5 m−1. The mean value velocities of the harvesting unit are 2.13-2.61 m·s−1, which is 0.17-0.21 Hz. The variances of oscillations in the header operating width, the cut crop’s swath width, and the disc harrow’s width are concentrated in approximately the same low-frequency range, the maximum value of which is small and does not exceed 0.9 m−1 or 0.37 Hz. The oscillation processes of the mowed crops’ stubble height have a higher frequency. The cutoff frequency of their normalized spectral densities is at the level of 3.0 m−1. In terms of time, considering the harvesting unit movement velocity of 2.13-2.61 m·s−1, this is 1.02-1.25 Hz. At the same time, oscillations in the stubble height of mowed crops are characterized by small variances, the maximum value of which does not exceed 11 cm2.
