Paddy field ridger

Abstract

The invention relates to a paddy field ridger, belonging to the field of agricultural machinery. The paddy field ridger comprises a rack, a ridge device, reamers and a gear box. The rack comprises a front shaft and a rear shaft, wherein the front shaft of the rack is symmetrically provided with the reamers, the rear shaft of the rack is provided with the ridge device, and a transmission shaft is arranged at the upper part of the rack. The gear box is arranged at the middle part of the transmission shaft, and an input shaft is arranged at the front part of the gear box. A gear at one side of the transmission shaft is connected with a gear on the front shaft through a chain, and a gear on the other side of the transmission shaft is connected with a gear on the rear shaft through the chain. Conical surfaces inclining outwards are symmetrically arranged on inner surfaces on two sides of the ridge device, and an inner surface at the intersect part of the conical surfaces is in a circular arc shape. The width of two ends of the ridge device is 40-70 centimeters, and the vertical height between the peak of the circular arc-shaped inner surface and the ground is 20-30 centimeters. The paddy field ridger has the beneficial effects that the quality is good, the production efficiency is high, the top surface and two side surfaces of a circular arc-shaped ridge are firmer and are smooth without water accumulation or weeds, and heights and widths of a soil layer after ridge construction are consistent.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a paddy field ridge building machine. Background technique [0002] As an important industrial sector in the national economy, agriculture takes land resources as the production object, and Heilongjiang Province, as a large agricultural province, also plays an important role. Heilongjiang has a relatively large rice planting area every year, so building ridges for rice fields has become a very important task. At present, the work of building ridges in rice fields is usually done manually. The height and width of the ridges built in this way are uneven, and the soil quality of the artificially piled ridges is relatively soft, especially the tops of the ridges are flat. Afterwards, a large amount of accumulated water will remain, making the ridge extremely soft, and the soil on the ridge will be lost after being washed by the rain, and it will easily collapse and lose the ori...

Problems solved by technology

At present, the work of building ridges in rice fields is usually done manually. The height and width of the ridges built in this way are uneven, and the soil quality of the artificially piled ridges is relatively soft, especially the tops of the ridges are flat. Afterwards, a large amount of accumulated water will remain, making the ridge extremely soft, and the soil on the ridge will be lost after being washed by the rain, and it will easily collapse and lose the original ridge building function. Long time, low work efficiency, often requires a lot of repetitive work, wasting a lot of human resources
