Abstract
The invention relates to a press roller of a deep scarifier. The press roller comprises traction arms, angle adjusting arms, mounted bearings, a press roller body, a mud scraping knife rest, crescent-shaped soil crushing teeth, mud scraping knives and main shafts. The upper ends of the traction arms and the angle adjusting arms are fixed to the rear end of a deep scarifier rack through pins. The lower ends of the traction arms are fixedly provided with the mud scraping knife rest through the mounted bearings. Meanwhile, the main shafts at the two ends of the press roller body are in transition assembling with the mounted bearings. The mud scraping knives are fixed to the inner side of the mud scraping knife rest. The crescent-shaped soil crushing teeth are fixed to the outer surface of the press roller body. The press roller is simple in structure and high in soil crushing capacity, the earth surface is level after the press roller works, and meanwhile the functions of adjusting the press roller height and automatic soil scraping are achieved.
Description
Technical field
The present invention relates to a kind of parts of agriculture Subsoiler machinery, be more particularly a kind of pack roller of subsoiler, belong to agricultural mechanical field.
Background technology
Pack roller is a kind of conventional agricultural tool, in the Subsoiler process of farmland, supports the use with subsoiler, can carry out effectively broken and compacting, improve grading, be conducive to the subsequent jobs such as sowing the large clod after Subsoiler.
At present, with the matching used pack roller of subsoiler mainly exist structural design unreasonable, work after poor, the pack roller of grading easily adhere to earth, the problems such as overcompaction caused to earth's surface, have impact on the effect of Subsoiler.
Summary of the invention
The present invention is directed to existing pack roller Problems existing, provide a kind of novel pack roller fixing forward and reverse crescent shape cutting on pressure roller, realize the large clod after to subsoiling and effectively shred, improve grading, reduce the effects such as the overcompaction of soil.In operation process, soil resistance makes pressure roller produce rotation, the adjacent reverse crescent shape hack tooth that roller surface is fixed can produce soil block effectively be cut and rout up effect, and the outer arc linear velocity of crescent shape hack tooth is greater than inner arc, spoiled soil cohesive force is more conducive under the effect of speed difference, strengthen the crushing effect to soil block after subsoiling, simultaneously, under adjacent crescent shape hack tooth reverse rotation effect, to the remarkable stirring action that surface of ploughing also produces incision and routs up, thus avoid, to the overcompaction of soil, improving land smoothing.On the other hand, by arranging scraper between adjacent teeth, when cutting rotates advance with pressure roller, scraper can adhere to soil to roller surface and effectively strike off, thus improves suppression performance, reduces operation resistance.This pack roller and subsoiler frame adopt anglec of rotation formula to be connected, and structure is simple, is easier to realize Height Adjustment.
Technical scheme of the present invention is: a kind of pack roller of subsoiler, comprises draft arm, angle adjustment arm, rolling bearing units, pressure roller, scrapes trowel frame, crescent shape hack tooth, scrapes trowel and main shaft.
Described draft arm upper end and angle adjustment arm are fixed by a pin to subsoiler frame rear end, draft arm lower end is fixed with by rolling bearing units and scrapes trowel frame, simultaneously, main shaft and the rolling bearing units transition at pressure roller two ends are assembled, scrape trowel to be fixed on and to scrape inside trowel frame, crescent shape hack tooth is fixed on pressure roller outer surface.
Described draft arm has angular adjustment groove, angle adjustment arm has two row's angle adjustment holes, by the cooperation between angular adjustment groove and different angle adjustment holes, the height on pressure roller distance ground can be regulated.
Described pressure roller cylindrical outer surface is longitudinally uniformly distributed 11 groups of crescent shape hack teeth, 11 groups of crescent shape hack teeth are at pressure roller axis direction equidistant arrangement, two adjacent groups crescent shape hack tooth fore-and-aft distance is 170 millimeters, the profile of tooth fixed-direction of two groups of adjacent crescent shape hack teeth is contrary, often group is uniformly distributed 4 crescent shape hack teeth, in the course of work, and the contour structures special due to crescent shape hack tooth and arrangement, the perturbation action to soil can be strengthened, be beneficial to the fragmentation to large clod.
Between two adjacent groups crescent shape hack tooth, arrange scraper, scrape trowel and be close to pressure roller cylindrical outer surface, when crescent shape hack tooth rotates advance with pressure roller, scraper can adhere to soil to roller surface and effectively strike off, and improves suppression performance, reduces operation resistance.
Described pressure roller length is 2060 millimeters, and diameter is 245 millimeters, and wall thickness is 5 millimeters, and the outer arc radius of crescent shape hack tooth is 120 millimeters, inner arc radius 90 millimeters, and hack transverse tooth thickness degree is 15 millimeters.
Pack roller structure of the present invention is simple, pretty good to the large clod crushing effect produced in Subsoiler process, has the function regulating pressure roller terrain clearance and automatic scraping simultaneously.

Embodiment
As shown in Figure 1, a pack roller for subsoiler, comprises draft arm (1), angle adjustment arm (2), rolling bearing units (3), pressure roller (4), scrapes trowel frame (5), crescent shape hack tooth (6), scrapes trowel (7), main shaft (8).
As shown in Figure 1, 2, draft arm (1) upper end and angle adjustment arm (2) are fixed on subsoiler frame (9) rear end by pin (10), draft arm (1) lower end is fixed with by rolling bearing units (3) and scrapes trowel frame (5), simultaneously, main shaft (8) and rolling bearing units (3) transition at pressure roller (4) two ends are assembled, scrape trowel (7) be fixed on scrape trowel frame (5) inner side, crescent shape hack tooth (6) is fixed on pressure roller (4) outer surface.
As shown in Figure 2,3, draft arm (1) has angular adjustment groove (11), angle adjustment arm (2) has two row's angular adjustment jacks (12), in Subsoiler process, cooperation between angular adjustment groove (11) from different angle adjustment holes (12), can regulate the terrain clearance of pressure roller.
As Fig. 1, shown in 4, pressure roller (3) cylindrical outer surface is longitudinally uniformly distributed 11 groups of crescent shape hack teeth (6), 11 groups of crescent shape hack teeth (6) are at pressure roller (4) axis direction equidistant arrangement, two adjacent groups crescent shape hack tooth (6) fore-and-aft distance is 170 millimeters, the profile of tooth fixed-direction of two groups of adjacent crescent shape hack teeth (6) is contrary, often group is uniformly distributed 4 crescent shape hack teeth (6), in the course of work, crescent shape hack tooth (6) is easy to cut soil, simultaneously because profile of tooth fixed-direction is contrary, the perturbation action to soil can be strengthened, thus be beneficial to the fragmentation of large clod.
