Extrusion type ditching machine

Abstract

The invention discloses an extrusion type ditcher. An extrusion cutter is utilized to extrude soil in a place needing to be ditched to be in a required shape, wherein a rotary tillage cutter shaft with intermediate transmission is arranged in front of a ditching cutter, and the rotary tillage cutter shaft is of a structure that rotary tillage cutters are on the two sides; the rotary tillage cutters firstly break the soil, and then the extrusion cutter operates; in order to prevent the soil on the two sides of a ditch from arching up in extrusion ditching, a compression roller is arranged in the front portion of the extrusion cutter; in order to prevent the extruded soil from piling on the two lateral sides of the ditch and prevent a field from being uneven, a soil division screw conveyer is arranged at the rear portion of the extrusion cutter to divide soil, and an inclined scraper blade is further utilized to scrape the divided soil to be flat; the height of the soil division screw conveyer and the height of the field can be adjusted; when ridges of a certain height need to be formed on the two lateral sides of the ditch, the height of the soil division screw conveyer and the height of the scraper blade are adjusted to be high, and the scraper blade can be disassembled. The extrusion type ditcher is complete in function, convenient to use and high in technical content, and has better application and popularization value.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural machinery cultivation, and in particular relates to an extrusion type ditching machine. Background technique: [0002] Ditches are widely used in agricultural planting and engineering technology, such as opening rectangular trenches for water-saving irrigation in farmland, laying water pipes or cables, and planting yams, etc. Therefore, there are many types, uses, shapes, sizes, and structures of ditches. The ditch is wide and shallow, and some are narrow and deep, such as narrow to 10cm and deep to 1.5m; some have a slope, some have no slope, and the slope is generally 30 to 60 degrees. It is obviously efficient to use manual excavation. Low, in order to adapt to different applications, there are now many types and multi-purpose trenchers with high work efficiency. [0003] In agricultural planting, the ditch is mainly to improve the performance of flood prevention and drought resistance i...

Problems solved by technology

The plow tool is used to directly cut into the soil, which has the advantages of simple structure, high productivity, and low energy consumption per unit of earthwork. The plow can squeeze the soil to a certain extent to form a furrow. Difference

[0009] The main problem of the above types of ditching machines is that they all use a single tool to mill or turn the soil (shared ditching machine) to achieve the purpose of ditching, but they can't make the ditch it should be. Using standards and service life, if the strength of the ditch surface is insufficient, the ditch surface is extremely easy to collapse under the erosion of rainwater, resulting in the loss of the function of the ditch; The water on the ground is very easy to seep out, which is not conducive to the water retention requirements of the crops, especially at the beginning of the sowing of the crops, when the crops are not growing, the water retention requirements are high

In addition, the existing trenchers are mainly designed for a ditch of one size, which limits the universal application of the trencher
