Paddy field rice direct sowing machine

Abstract

The invention provides a paddy field rice direct sowing machine. A machine head of a paddy field walking power chassis assembly is hinged to the front end of a lifting device, the rear end of the lifting device is hinged to the front end of a hanging assembly, the rear end of the hanging assembly is hinged to the middle of a main support frame, horizontal profiling devices symmetrically arranged at the left end and the right end of the main support frame are hinged to the two sides of the hanging assembly, and seed arrangement devices are fixedly connected to the main support frame in rows atequal intervals; ditching and ridging devices are symmetrically hung on the main support frame from left to right; one end of an elevation profiling device is hung on the main support frame, and the other end of the elevation profiling device is connected with a paddy field walking power chassis assembly; the power input end of a transmission system is connected with a power output shaft arrangedbelow a frame of the paddy field walking power chassis assembly, the power output end of the transmission system is connected with the seed arrangement devices, rice direct sowing is realized throughcomposite transmission of the a gear and a chain wheel, and the paddy field rice direct sowing machine has functions of precision hole direct sowing, selectable seeding row spacing, adjustable soil inlet angle of the ditching and ridging devices, horizontal elevation profiling and the like, and is high in practicability.

Description

Technical field [0001] The invention relates to the technical field of direct seeding of agricultural machinery, in particular to a direct seeding machine for paddy rice. Background technique [0002] my country is a large country with 37.3 million hectares of paddy fields. The annual rice planting area is about 30 million hectares, accounting for 30% of the country’s cereal planting area; 1.5×10 farmers 8 Households, accounting for about 60% of the total number of farming households; the total annual output of rice is nearly 200 million tons, accounting for 40% of the country’s total grain output. With the rapid development of agricultural machinery, direct seeding of machinery can save seedlings and transplanting links, and has the advantages of high efficiency, cost-saving and labor-saving, and easy operation, which is becoming increasingly popular with farmers. [0003] However, due to the different depths of mud feet in the southern paddy fields and the large differences in th...

Problems solved by technology

[0003] However, due to the different depths of mud feet in the southern paddy fields and the large differences in the soil flow characteristics of the pre-treatment of the regional mechanical direct-seeding fields, higher requirements are put forward for the field profiling function and field passing performance.
