摘要

研究了施肥机的载荷、轮胎尺寸、驱动轮数量等参数对基本开发指标数值和土壤压实度的影响。在不同耕地面积的农场进行了研究试验。研究的范围包括调查表调查、实验室和开发试验、受精单位的比较评价、获得的结果的核查以及实际使用的建议。观察到生产力显著提高(从0.38公顷/小时增加到1.15公顷/小时)，同时播种机的负荷能力也有所增加，但发现以下指标有所下降:土壤表面压实度(从44%到15%)、田间负荷(从412到165千牛∙公里)和沟槽体积(从165到67立方米)。装载量为20 t的四轮吊具，其现场负荷指标(357 kN∙km)、槽载(204 kN/m)和槽容(110 m3)均比装载量为10 t的两跟吊具高2倍。

SOIL COMPACTION WITH WHEELS OF MANURE SPREADER AGGREGATES

The study focused on the definition of the impact of the parameters of the applied manure spreaders (loading capacity, size of tyres, the number of driving wheels) on the numerical values of the basic exploitation indices and on soil compaction as well. Research tests were carried out on farms of different arable land areas. The scope of the study included questionnaire surveys, laboratory and exploitation tests, comparison evaluation of fertilization units, verification of the acquired results, as well as recommendation for practical use. A significant growth in productivity (from 0.38 to 1.15 ha/h) was observed together with an increase in the loading capacity of the spreaders, but the following indicators were found to have decreased: surface of soil compaction (from 44 to 15%), field loading (from 412 to 165 kN∙km) and grooves volume (from 165 to 67 m3). Four-wheel spreader of 20 t loading capacity has been characterized by two times higher values of field loading indices (357 kN∙km), groove loading (204 kN/m) and groove volume (110 m3) in comparison with a two-heel spreader with a loading capacity of 10 t.

期刊介绍： At present, transport is one of the key branches playing a crucial role in the development of economy. Reliable and properly organized transport services are required for a professional performance of industry, construction and agriculture. The public mood and efficiency of work also largely depend on the valuable functions of a carefully chosen transport system. A steady increase in transportation is accompanied by growing demands for a higher quality of transport services and optimum efficiency of transport performance. Currently, joint efforts taken by the transport experts and governing institutions of the country are required to develop and enhance the performance of the national transport system conducting theoretical and empirical research. TRANSPORT is an international peer-reviewed journal covering main aspects of transport and providing a source of information for the engineer and the applied scientist. The journal TRANSPORT publishes articles in the fields of: transport policy; fundamentals of the transport system; technology for carrying passengers and freight using road, railway, inland waterways, sea and air transport; technology for multimodal transportation and logistics; loading technology; roads, railways; airports, ports, transport terminals; traffic safety and environment protection; design, manufacture and exploitation of motor vehicles; pipeline transport; transport energetics; fuels, lubricants and maintenance materials; teamwork of customs and transport; transport information technologies; transport economics and management; transport standards; transport educology and history, etc.
