Abstract

The residual agricultural plastic film in China is not easily recovered due to the thinness and poor mechanical properties of domestic films, and a large amount of plastic film remaining in farmland soil poses a great threat to soil quality and crop production. A spring-tooth residual plastic film collector (SRPFC) is widely used in domestic residual plastic film (RPF) recycling operations. However, there are two major problems in the current SRPFC: the low recovery rate of the residual film (RRRF) caused by the difficulty of film-stripping and the high impurity rate in the film (IRF). In this paper, a stripping and impurity removal device (SIRD) is designed to address the existing problems of SRPFC, which is mainly composed of film-stripping tooth plates (FTP), two wind-collecting hoods, and two centrifugal fans. The motion and force analysis of the RPF in the film-stripping process was carried out, and the arc FTP was determined to be used for film-stripping. The size parameters of the FTP were obtained by establishing the coordinate system to solve the differential equation. By comparing and analyzing the force of RPF in the airflow field of the test bench for suspension speed and the airflow field of the wind-collecting hood, the RPF equivalent particle was established. The discrete phase model (DPM) in Fluent software was used to simulate the movement of the RPF equivalent particle, and the calculated air volume range of the centrifugal fan was 5501.88~6829.92 m3/h. The effects of forward speed, rotating speed of film conveying chain harrow (FCCH), and rotating speed of the centrifugal fan on RRRF and IRF were studied by orthogonal rotary combination experiment. The test results showed that the best combination of machine operation parameters was when the forward speed was 5 km/h, the rotating speed of the FCCH was 235 r/min, and the rotating speed of the centrifugal fan was 1978 r/min. Under these conditions, the RRRF was 92.53%, and the IRF was 9.31%. Field experiments were carried out with the rounded parameters, and the average RRRF was 92.07%, and the average IRF was 9.56% under the parameter combination, indicating that the optimization scheme of the device was feasible.

Abstract

The development of combine harvester has greatly promoted the development of global agricultural mechanization, In this paper, a large number of research results related to power allocation of combine harvesters were collected, The development status of combined harvester transmission system and power test system is summarized through analysis and selection, It is found that there are few researches on the power distribution of the combine harvester, so it is necessary to further study the related research of the combine harvester.

Abstract

Previous studies about superoxide dismutase (SOD) genes were mostly with regard to biotic and abiotic stress responses. Some reports have indicated SOD genes may play an important role in plant development. However, little is known about the relationship of SOD genes with grape berry ripening. Thirteen VviSOD genes were identified from grape genome sequences based on the bioinformatic method. Phylogenetic analysis indicated that these VviSODs could be divided into two groups. The genes of VviCu/ZnSOD1a and VviCu/ZnSOD1c were identified as tandem replication genes. The expression analyses based on RNA-Seq and qRT-PCR results in 'Kyoho' and its early-ripening bud mutant, 'Fengzao', demonstrated that the VviSOD genes involved in the grape berry ripening and VviCu/ZnSOD1c were the main candidate. Sequence analysis of VviCu/ZnSOD1c gene in 'Fengzao' showed that the coding sequence was the same as that of 'Kyoho'. According to the bioinformatic and expression analysis, VviSOD genes probably involved in the grape berry ripening and VviCu/ZnSOD1c was selected as the main candidate to further explore its potential role in the early ripening of 'Fengzao'.

Abstract

Byline: Pingyu Jiang, Guohai Zhang In this paper, we propose a portalet-based architecture with which e-service functions through calling CAX tools remotely can be realised. Furthermore, as the core of the portalet, the contexts of calling mode service, queueing and managing service, visual I/O service and collaborative service are discussed in detail. In order to verify the feasibility of the method proposed, a running example is given.
