Abstract:

Abstract Rotary tillers often have shallow plowing depth and serious leakage problems in the specific working process, resulting in a decrease in the rate of soil breaking and stubble breaking, causing damage to mechanical devices. In this paper, we conducted a field test on the popular self-propelled rotary tiller to obtain the changes in the operating Indexes of various types of knife roller operation with time under three types of tillage environments; we conducted a force analysis and finite element analysis on the IT245 rotary tiller to obtain the stress effect and deformation of the rota

Abstract:

Rotary tillers implements are now projected as important tillage machinery for better seedbed preparation; however the ordinary rotavator being in line with the tractor center line at the rear cannot be used in orchards due to the hindrance posed due to narrow space between the plants. Therefore, the concept of a rotary offset tiller in other words orchard tillers was proposed, which could perform finer intercultural operation between the plants. Since there are some models of Indians and Foreign made rotary offset tiller available and their work quality parameter significantly plays a crucial

Abstract:

A rotary tiller or rotavator is active tillage equipment used to prepare farmland for sowing seeds, weeding, mixing manure and fertiliser into the soil, crushing soil blocks, etc. Compared with conventional farming, the advantages of this equipment are rapid seedbed preparation and reduced draught. Nowadays, the utilisation rate of rotary tillers has increased. However, the blades are the key component that engages with the soil in the rotary tiller. These blades interact with the soil differently from ordinary ploughs and bear impact loads and high frictional forces, which eventually generate

Abstract:

Abstract. Submerged reverse rotary tillage was presented decades ago as a way to save energy in deep tillage, but its application was limited because it throws the tilled soil forward. The forward-thrown soil gets re-tilled, resulting in wasted energy. To understand the soil throwing process during reverse rotary tillage, a theoretical soil throwing model was established, but that model was investigated by few tests. How soil is thrown by a submerged reverse rotary tillage system is, as yet, not clear. To optimally design a submerged reverse rotary tiller, it is necessary to reveal how soil is

Rotary burying by tractor-hitched rotary tillers is a common practice in southern China for treating rice stubbles. Currently, it is difficult to maintain stable tillage depths due to surface unevenness and the residual stubbles in the field, which leads to unstable tillage quality and nonuniform crop growth in later stages. In this study, an RTK-GNSS was used to measure the real-time height and roll angle of the tractor, and a variable-gain single-neuron PID control algorithm was designed to adjust the coefficients (KP, KI, and KD) and gain K in real-time according to the control effects.

It has been established that the Maltese-cross mechanism including a three-fi nger carrier

Abstract:

A method of calculation for the moment of soil resistance to the rotation of rotary blade tool depending on an angle of rotation and on the maximum drive power is developed on the basis of suggested mathematical model of interaction of tool with the soil. This method allows to simplify the experiments on determination of power characteristics of the tool and to reduce their amount considerably. Due to the community of basic points the offered technique can be basically transferred on other rotary tools.

Abstract:

In order to improve the performance of tillage tool for straw incorporation in silty clay loam, a combined tillage implement with plough and rotary tiller was designed. Its performance on straw incorporation and power consumption was investigated, and the combined tillage types (CTSR and CTDR) were compared with traditional tillage types including a sole plough type (SP and DP), a sole rotary tiller (RT), and a two-pass tillage type (SP+RT and DP+RT) in a rice field experiment. The effect of the forward speed and rotary speed for RT and CTSR were studied by DEM simulation. The ratio of straw c

Abstract:

A field experiment was conducted to study the performance of CIAF: animal drawn puddler in respect of puddling quality and economical aspect under wet silty loam soil conditions. Puddling quality was judged on the basis of puddling index, bulk density, percolation loss and crop yield. The performance of animal drawn puddler in terms of puddling index and percolation loss was found better as compared to puddling by rotary tiller and conventional method of puddling. The field capacity and field efficiency were observed O. 10 ha/h and 71.42 percent in case of animal drawn puddler, which were 87 a

Abstract:

The rotary tiller with ‘L’ shaped blades was examined for torque, power and specific tilling energy requirements to attain optimum soil-machine operational parameters. The three levels of moisture content (11.4%, 12.8% and 14.6% (d.b)), three speed ratios of 20 (?1), 12 (?2) and 9 (?3) at different passes (first, second and third) with rotational speed of 262 rpm were selected for study. The observations indicated inverse relation between torque and power requirement to moisture content. The lowest value of torque of 16.54 N-m and 26.66 N-m was associated with sandy loam and clay loam soil und

Abstract:

This article presents the technological working process of the rotary softener developed for the chisel-cultivator; results of experimental studies carried out to justify its parameters. The type of soil and its physic-mechanical properties are the main factors in the selection of the working bodies of the soil tillage machine and assessment of aggregate performance. The researches are carried out mainly in grassy, pale gray and barren soils, and the physic-mechanical properties of the soil in irrigated fields of the Republic of Uzbekistan have been sufficiently studied.
