Description
Technical Field
The invention relates to the field of ditching machines, in particular to a cutter set for ditching.
Background
In the prior art, the ditcher mainly comprises a large and medium-sized ditcher and a micro-sized ditcher, wherein the ditching modes of the large and medium-sized ditcher mainly comprise a chain cutter type, a disc cutter type, a spiral type and the like, and the micro-sized ditcher respectively comprises a hoe shovel type, a wing shovel type, a boat shovel type, a core share type, a single disc type, a double disc type, a sliding cutter type and other ditching modes according to different soil penetration angles; the large and medium-sized ditcher is mainly suitable for digging compartment ditches, surrounding ditches, ditch and various ditches and grooves in pipe network construction such as underground pipeline laying, electric (optical) cable laying and the like in agricultural production. The large and medium-sized machines are not suitable for small-sized field operations in agricultural production, and generally used for seeding, fertilizing, irrigating and the like in the field planting industry of small-sized fields are all micro ditchers, so that small vegetable fields, fruit garden fields, crop row fields and greenhouse planting fields are widely used at present.
However, in the field of ditching machines, in particular to a micro-miniature ditching machine, a hoe-shovel type ditching mode, a wing-shovel type ditching mode, a boat-shaped ditching mode, a core-share type ditching mode, a single-disc type ditching mode, a double-disc type ditching mode, a sliding-knife type ditching mode and the like are used, and the common characteristics of the ditching machines are that the ditching machines do not generate any rotary cutting to soil, and only the ditching machines are dragged to advance by means of external force, so that the ditching machines extrude and separate the soil to form grooves to achieve ditching and forming. The mode requires that the soil is soft, so the method is only suitable for some places in the north of China or is limited in use ratio and use method because the secondary ditching operation is carried out after the soil is subjected to loose farming industry. The ditching cutter type ditching mode is an operation mode of cutting and throwing and withdrawing the soil to form a ditch by means of the rotation function of the working cutter, and is greatly improved compared with the prior ditching mode, the ditching cutter type ditching cutter has the advantages that the ditching cutter type ditching cutter is possible for ditching hard soil, however, the working cutter is arranged at two ends of a horizontal shaft of a box body of the ditcher, the rotation of the ditching cutter can only operate on areas corresponding to the two ends of the box body, a boss is formed at a position below the box body of the ditcher where the working cutter cannot be rotated, and the formation of the ditch is substantially influenced by the existence of the boss. Meanwhile, the ditching tool is prevented from entering the ground, so the ditching depth is also greatly limited, which is the fundamental reason that the ditching machine of the same type has less ideal effect when working on hard ground. In order to overcome the defects, in the traditional technology, a small shovel is arranged at a relevant position below a box body of the furrow opener, and the small shovel is used for shoveling off a formed boss in the operation process.
Therefore, the ditching mode of the existing ditcher needs to be improved, so that the ditcher is easy to dig in hard land, good in ditch formation, low in power consumption and convenient and easy to operate.
