Ditching fertilizer applicator capable of adjusting depth

Abstract

The invention discloses a ditching fertilizer applicator capable of adjusting the depth, which comprises an adjusting gear lever, a drive housing body, a first transmission shaft, a second transmission shaft, a third transmission shaft, a transmission chain, a housing, a ditching knife, a furrowing plough, a land wheel, a fertilizer can and a third shaft chain. The ditching fertilizer applicator is an agricultural machine that can ditch and fertilize at the same time, and the adjusting gear lever adjusts the drive housing body so as to adjust the ditching depth, so that the ditching depth can be adjusted directly; the ditching fertilizer applicator is directly connected with a gear of a rear output gear box of a tractor through the drive housing body, the power consumption of a traction structure can be avoided through the gear transmission, and power loss is reduced; and meanwhile, the ditching fertilizer applicator can be used in different sections conveniently, and can carry out the operations such as independent ditching, rotary tillage, weeding, ridging, hilling, ditching fertilization and the like through simple adjustment.

Description

Technical field: [0001] The invention relates to an agricultural machine, in particular to a ditching and fertilizing machine whose ditching depth can be adjusted. Background technique: [0002] At present, the agricultural ditching machines matched with tractors have been widely used. The rear-mounted ditching machines can generally be divided into special-purpose and combined types; special-purpose ditching machines are dedicated to ditching operations. It is a single function; the combined trencher generally includes a trencher and a rotary tiller, but the overall structure of the current combined trencher is relatively complicated, and the power input and output are through an indirect connection mechanism, such as a pulling mechanism. Part of the power of the trencher must be consumed in power transmission, and the repair and maintenance costs are relatively high. [0003] At present, the existing agricultural machinery has a single function, and the combination of dit...

Problems solved by technology

[0002] At present, the agricultural ditching machines matched with tractors have been widely used. The rear-mounted ditching machines can generally be divided into special-purpose and combined types; special-purpose ditching machines are dedicated to ditching operations. It is a single function; the combined trencher generally includes a trencher and a rotary tiller, but the overall structure of the current combined trencher is relatively complicated, and the power input and output are through an indirect connection mechanism, such as a pulling mechanism. Part of the power of the trencher must be consumed in power transmission, and the repair and maintenance costs are relatively high

[0003] At present, the existing agricultural machinery has a single function, and the combination of ditching machine, seeder, and fertilizer applicator is complicated, and it is difficult to realize the whole farming operation such as ditching, tillage, sowing or fertilization at the same time.

[0004] For the current rotary tillage ditching machine, the ditching depth is generally determined when the ditching machine is installed, and it is difficult to adjust the ditching depth. When encountering different plots, especially vegetable greenhouses, economic gardens, etc. It is inconvenient to use at the same time, so the application is not popular enough, and there is an urgent need for a ditching machine with adjustable ditching depth and easy adjustment.
