Roller type rice fertilization and direct seeding combinational machine

Abstract

The invention belongs to agricultural machinery and discloses a roller type rice fertilization and direct seeding combinational machine. A W-shaped rolling type fertilizer furrowing and ridging roller assembly and a trapezoidal rolling type seeding ridge forming and power drive roller assembly are mounted on a frame. First and second drive sprockets are fixedly mounted on the trapezoidal rolling type seeding ridge forming and power drive roller assembly, a first chain sleeves the first drive sprocket and a first sprocket, and a second chain sleeves the second drive sprocket and a second sprocket. The W-shaped rolling type fertilizer furrowing and ridging roller assembly is formed by assembly of conical large and small rollers at intervals, the trapezoidal rolling type seeding ridge forming and power drive roller assembly is formed by assembly of trapezoidal rollers and cylindrical rollers at intervals, and longitudinal center lines of the conical large rollers and the conical small rollers are coincided with those of the corresponding trapezoidal rollers and cylindrical rollers on rear side respectively. The roller type rice fertilization and direct seeding combinational machine has the advantages of novel, reasonable and simple structure, reliability in use, few faults, high fertilizer utilization rate, remarkable yield increasing effects and low power consumption in operation.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a combined operation machine tool for rice fertilization and direct seeding. Background technique [0002] At present, in Heilongjiang Province, the rice planting method of direct seeding operation accounts for about 15% of the total area, and the rural rice planting method of direct seeding in the eastern region accounts for more than 50%, and more than 95% of Chinese farmers who plant rice in the Russian Far East use Live rice cultivation. Because this planting technology does not require rice seedling raising and transplanting operations, it has the characteristics of simple process, low labor intensity, low production cost, and can be sown in advance. This agronomic technology has been used until now. In order to meet and adapt to the needs of rice direct seeding operations, rice direct seeding machines have been used, but because the machine adopts a ship-plate support structu...

AI Technical Summary

Problems solved by technology

In order to meet and adapt to the needs of rice direct seeding operations, rice direct seeding machines have been used, but because the machine adopts a ship-plate support structure, and can only complete a single direct seeding operation, it cannot complete the operations of sowing and fertilization simultaneously, and the traction resistance is large and the operation is single. The low yield of rice is a technical problem that needs to be solved

In order to solve the above problems, the applicant has developed a wheeled rice wide and narrow row direct-seeding fertilizer applicator with a combined structure of deep and shallow fertilization double-disc openers and cylindrical pressure rollers. Due to structural design defects, there are operational effects. technical issues and poor quality work
