Abstract
The invention relates to agricultural machinery, in particular to a subsoiler used together with a four-wheel tractor. In the subsoiler used together with the four-wheel tractor, a subsoiling shovel shaft fixing element is welded on the back side of a subsoiler large frame; a leveling roller is in hinged connection with the subsoiler large frame through the upper end of a leveling roller connecting piece; a subsoiling shovel arrow faces a ditching disc and is in welded connection with the lower end of a subsoiling shovel shaft; the ditching disc is fixed on a side plate of the subsoiler large frame through a ditching disc shaft and a bearing seat; and a depth limiting wheel is fixed at the front end of the subsoiler large frame through a depth limiting wheel positioning piece. The subsoiler realizes subsoiling operation of the four-wheel tractor, has a simple structure, is convenient to operate, improves operation efficiency and lowers the requirements on intensities of the subsoiling shovel shaft and parts. In particular, the problem of unavailable cultivating by using the ordinary subsoiler during grassland subsoiling is solved and the aim of performing protective cultivation is fulfilled. The subsoiler used together with the four-wheel tractor is suitable for subsoiling on hard soil or grasslands.
Description
Technical field
The present invention relates to a kind of agricultural machinery, specifically relate to the subsoiler that a kind of four-wheel tractor uses.
Background technology
Along with improving constantly of agricultural mechanization degree, the various agricultural machinery that are applied to farming, results, ridging, fertilising etc. provide convenience for the farming of vast farmers.But the subsoiler that in the returning farmland to grassland of grassland, uses, because the turf on grassland is thick especially, grass roots is deep-rooted, common subsoiler can't be deep ploughed at all.And at present be used for the grassland returning farmland to grassland and also can flatten the subsoiler in soil subsequently in trench digging, deep ploughing soil, back earlier with four-wheel tractor uses, yet there are no record.
Summary of the invention
What the present invention will solve is the deficiency that exists at prior art, the subsoiler that provides a kind of four-wheel tractor to use.
The subsoiler that a kind of four-wheel tractor of the present invention uses is achieved by following technical proposals: the subsoiler that a kind of four-wheel tractor uses comprises speed changer, protective cover, deep soil loosing shovel handle fixture, the deep soil loosing shovel handle, the leveling roller, the flattening roller sub-connecting member, deep soil loosing shovel, bearing block, the trench digging disk, the roller limited block, gauge wheel, the gauge wheel keeper, big of subsoiler, hanger, the hanger bracket support member, hanger bracket, big side plate of subsoiler, the trench digging disc shaft, roller axle, intermediate transverse girder, described speed changer is fixed on big upper center of subsoiler, and speed changer links to each other with the trench digging disc shaft by gear; It is at regular intervals and parallel with big upper surface of subsoiler that described protective cover is installed in trench digging disk top, and big the inboard in the edge of protective cover and subsoiler is connected; Described deep soil loosing shovel handle fixture is welded on big rear side of subsoiler; Described deep soil loosing shovel handle is fixed on big of the subsoiler by deep soil loosing shovel handle fixture; Described leveling roller adopts reinforcing bar to distribute according to cage type around equally spaced four roller disks and is welded, the roller disk is fixed on the roller axle by bearing and bearing block, the roller axle both ends are fixed on flattening roller sub-connecting member lower end by bearing and bearing block, and flattening roller sub-connecting member upper end is articulated and connected with big of subsoiler; Described deep soil loosing shovel arrow is welded to connect towards trench digging disk and deep soil loosing shovel handle lower end; Described bearing block is fixedly mounted on big biside plate of subsoiler, and the trench digging disk is fixed on big side plate of subsoiler by trench digging disc shaft and bearing block; Described roller limited block is fixedly mounted on flattening roller sub-connecting member front end below on big side plate of subsoiler; Described gauge wheel is fixedly mounted on big front end of subsoiler by the gauge wheel keeper, and big of described subsoiler comprises big side plate of subsoiler and intermediate transverse girder.
The subsoiler that a kind of four-wheel tractor of the present invention uses has following beneficial effect compared with prior art: because the subsoiler that a kind of four-wheel tractor of the present invention uses is provided with the trench digging disk, and the cutting edge edge of the ditch disk that opens the light is set to groove shape, whole disc like saw blade under axle drives cutting soil particularly the turf grass roots is ready for the operation of loosening the soil of next step deep soil loosing shovel, reduce deep soil loosing shovel handle and the resistance that pan soil earth directly contacts, prevent the damage of deep soil loosing shovel handle.Entire machine is connected on the speed changer of tractor by hanger, hanger bracket and support member are outstanding.The power of tractor output is connected on the splined shaft of described speed changer by universal drive shaft, through the processing of speed changer with transmission of power to the axle at trench digging disk place, axle drives the purpose that three trench digging disk high speed rotating are realized cutting soil and turfs, for next step deep soil loosing shovel buries ready.Deep soil loosing shovel and deep soil loosing shovel handle thereof progressively extend in the cutting seam of soil when complete machine descends, put latter two gauge wheel and will contact earlier when lifter drops to qualifying bit with subsoiler with ground, the continuation of restriction complete machine descends, thus the dark loose degree of depth of restriction deep soil loosing shovel in soil.Along with the mobile deep soil loosing shovel handle of tractor will move along the groove that the trench digging disk is held successfully, deep soil loosing shovel can begin the operation of loosening the soil in the soil of face of land lower floor.Make the face of land uneven because bottom, face of land soil is loosening, the leveling rod of trailing behind the deep soil loosing shovel handle is suppressed the face of land smooth.The operation subsoiler that finishes is mentioned by the tractor lifter, closes power output trench digging disk and quits work, and deep soil loosing shovel handle and deep soil loosing shovel are extracted soil, the leveling roller can be under the support of roller limited block built on stilts.
The present invention has realized the dark loose operation of four-wheel tractor, and is simple in structure easy to operate, improved operating efficiency, reduces the requirement of strength of deep soil loosing shovel handle and parts.The difficulty that common subsoiler can't farming when particularly having solved the grassland deep ploughing reaches the conservation tillage requirement.The subsoiler that a kind of four-wheel tractor of the present invention uses is applicable to than pan soil earth or grassland deep ploughing and uses.
