A broken soil throwing and ditching device matched with a rotary tiller

Abstract

A pulverizing soil dispersal ditching device matched with a rotary cultivator comprises a cutter shaft which is connected with a conveyer driven shaft of the rotary cultivator, a rotary tillage cutter head which is arranged on the cutter shaft and a soil separating board which is fixed on the rotary cultivator, and is characterized in that the rotary tillage cutter head comprises a first bent cutter head, a second bent cutter head and a straight cutter head; the first bent cutter head is arranged in the middle of the cutter head, the straight cutter head is symmetrically arranged on the cutter head with the first bent cutter head as the center, the second bent cutter head is arranged on the cutter head between the straight cutter head and the first bent cutter head, wherein the first bent cutter head, the second bent cutter head and the straight cutter head have the same diameter; a plurality of first right angled bent cutters provided with straight cutting edges are symmetrically arranged on the first bent cutter head with the axis of the cutter shaft as the center. By means of novel arrangement of the rotary tillage cutters, the ditching mode is changed, the soil pulverizing rate and the ditching rate are improved, and the ditching width can reach 20 cm-30 cm; the pulverizing soil dispersal ditching device is simple in structure, convenient to use in various rotary cultivators, low in cost, convenient to assemble and unassembled, and higher in ditching quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a broken soil throwing and ditching device matched with a rotary tiller. Background technique [0002] With the development of the modern agricultural system, agricultural intensification and mechanization are inevitable trends. For crop rotation, stubble and no-tillage, etc., the research on ditching technology corresponding to it has emerged. In southern paddy field agricultural production, ditches and drainage in the field to lower the groundwater level are important measures for high-yield winter crops such as green manure and rapeseed. At present, the common trenchers on the market are divided into two categories, that is, the type with power output shaft and the type without power output. Ditchers without power output generally tend to cause soil accumulation on both sides of the ditch, thereby affecting the growth of crops in rotation and stubble beside th...

Ditchers without power output generally tend to cause soil accumulation on both sides of the ditch, which affects the growth of crops in rotation and stubble beside the ditch

For ditching machines with power output, a soil divider is generally installed above the ditching plate to prevent soil accumulation on both sides of the ditch, but the ditching plate is separated from the soil divider, and the ditching plate is a machete disc. On the one hand, it cannot be used The ditching plate is close to the ditching plate, which will easily cause the soil on both sides of the ditch to be scattered in the ditch. On the other hand, the machete disc will cause the façade on both sides of the ditch to be loose, which will easily cause the ditch to collapse and affect the quality of the ditching; at the same time , the position of the blade on the rotary tiller of the existing ditching machine is fixed, and the width of the ditch is fixed accordingly, which is not conducive to controlling the width of the ditch; in addition, due to the influence of the geographical environment, it is difficult to control the soil humidity of the paddy fields in the south, and the existing ditching The machine is easily affected by the humidity of the field mud, so it is difficult to open the ditch; in addition, the rice straw in the paddy field is returned to the field, and the ditching device is easy to be entangled; and the function of the ditching machine is fixed and single, so it is difficult to promote it in a large area in the southern paddy fields
