Paddy field boat type deep fertilization ditcher and monitoring method thereof

Abstract

The invention discloses a paddy field boat type deep fertilization ditcher and a monitoring method thereof. The paddy field boat type deep fertilization ditcher comprises a ditching body and a fertilizer feeding pipe; the ditching body comprises a boat body, an upper cover plate, a fertilizer homogenizing plate and a blade; the boat body comprises two cambered surface plates which are arranged ina bilateral symmetry mode; an exhaust device comprises an exhaust pipe and an exhaust pressure adjusting device which are connected to an exhaust hole of the upper cover plate, and a gas pressure adjusting spring, wherein the exhaust pressure adjusting device comprises a gas pressure adjusting sleeve which is connected to the middle upper part of the exhaust pipe in a sleeving mode through threads, and a piston which is arranged in the exhaust pipe in a lined mode, and one end of the gas pressure adjusting spring abuts against the piston, and the other end of the gas pressure adjusting springabuts against the gas pressure adjusting sleeve; and exhaust through holes are formed in the circumferential face of the exhaust pipe. Fertilizer enters from the fertilizer feeding pipe along with a gas flow, the certain gas pressure can be formed in a cavity of a fertilizer discharging device under the effect of the exhaust device at a fertilizer discharging opening, thus slurry can be preventedfrom flowing backwards to ensure that the fertilizer falls into the requirement depth smoothly and accurately, meanwhile the gas flow is discharged from an exhaust opening to prevent the situation that a large amount of gas flows out from a fertilizer outlet, and then bubbles are generated in the slurry.

Description

technical field [0001] The invention belongs to the technical field of ditching and fertilization in agricultural machinery, and in particular relates to a paddy field boat-shaped deep fertilization ditch opener and a monitoring method. Background technique [0002] Deep application of chemical fertilizers is conducive to improving the utilization rate of chemical fertilizers, and at the same time, it can also prevent fertilizer loss and water pollution caused by drainage to a certain extent. The technology of deep fertilization in paddy fields in my country has been applied to some extent, but it is still insufficient compared with the relatively mature technology of deep fertilization in dry land. During operation, muddy water is likely to backfill the ditch opener at the fertilizer outlet, causing fertilizers to fail to reach the specified depth or even accumulate near the fertilizer outlet and cannot be discharged. In addition, existing ditch openers are rarely equipped w...

Problems solved by technology

This invention patent can only adjust the depth of the ditch, and prevent the mud from clogging the fertilization hole through the fender. This structure has poor effect, and it will still block the fertilization hole after a long time
