Description
Technical field
The utility model relates to ditching machine technical field, specifically, relates to a kind of furrowing machine knife disc assembly.
Background technology
China is large agricultural country, grain and victual cultivated area large, cultivated area as the economic crops such as potato, great Jiang, garlic, shallot on the ground such as Shandong, Henan, Yunnan, northeast has accounted for sizable ratio, and needs when planting these economic crops to use that ditching machine is ditched to farmland, ridging operation.
At present, two cutterheads that ditching machine is provided with mostly are vertical and be arranged in parallel, the ditching machine Problems existing of this structure is: because the box location of the transmission case of ditching machine is lower, ditching machine move ahead ditching operation time, casing is vulnerable to the obstruction of front portion and underlying soil, current not smooth, before making ditching machine, line speed is low, reduces the trench digging efficiency of ditching machine.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of furrowing machine knife disc assembly, ditching machine move ahead ditching operation time, avoid casing to be subject to the obstruction of soil, ditching machine passes through smooth and easy, improve before line speed and trench digging efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: furrowing machine knife disc assembly, comprise output shaft, the casing that described output shaft is installed on transmission case is horizontally disposed with, the both sides of described casing are fixedly connected with end cap respectively, the two ends of described output shaft pass described end cap respectively and are provided with cutterhead, the two ends of described output shaft are separately installed with rzeppa joint, described output shaft is fixedly connected with the inner race of described rzeppa joint, one end of the cutterhead installing hole of described cutterhead is fixedly connected with the spherical shell of described rzeppa joint, the other end of described cutterhead installing hole is provided with bearing, the inner ring of described bearing is arranged on the periphery of bearing block, described bearing sleeve is on described output shaft and its one end is fixedly installed on described end cap, the outboard end of described bearing block is relative to the downward-sloping setting of described output shaft.
Preferably, described end cap and described bearing block are welded to connect.
Preferably, described bearing adopts deep groove ball bearing.
After have employed technique scheme, the beneficial effects of the utility model are:
Because the two ends of output shaft are fixedly connected with the inner race of rzeppa joint, the cutterhead installing hole of cutterhead is fixedly connected with the spherical shell of rzeppa joint, makes the varied angle transmission that can realize power between output shaft and cutterhead; Because cutterhead installing hole is arranged on the periphery of bearing block by bearing, and the outboard end of bearing block is relative to the downward-sloping setting of output shaft, the lower end of cutterhead is sloped inwardly, when cutterhead rotates, cutterhead soil that the is casing of transmission case is anterior and bottom digs out, and dishes out to both sides, thus the front portion of casing and bottom can not accumulate soil, ditching machine passes through smooth and easy, ditches without hindrance, improves the trench digging efficiency of ditching machine.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.

In figure: 1-casing; 2-cutterhead; 21-cutter tooth; 3-output shaft; 4-power gear; 5-deep groove ball bearing; 6-weldment; 61-end cap; 62-bearing block; 7-rzeppa joint; 71-inner race; 72-spherical shell; 73-steel ball; 74-retainer.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of furrowing machine knife disc assembly, comprise the output shaft 3 of level, output shaft 3 rotates and is installed on the casing 1 of transmission case, output shaft 3 key is connected with the power gear 4 be in transmission connection with power set, and the two ends of casing 1 are installed with end cap 61 respectively, and the two ends of output shaft 3 pass end cap 61, the two ends of output shaft 3 are connected with cutterhead 2 respectively by rzeppa joint 7, and cutterhead 2 is provided with several cutters tooth 21.
The two ends of output shaft 3 are separately installed with rzeppa joint 7.
As shown in Figure 1, rzeppa joint 7 comprises: inner race 71, retainer 74, steel ball 73 and spherical shell 72; Wherein, the lateral wall of inner race 71 is provided with some interior raceways, and the madial wall of spherical shell 72 is provided with the outer raceway of some and interior raceway adaptation, and be provided with steel ball 73 between relative interior raceway and outer raceway, steel ball 73 constrains in retainer 74; When inner race 71 rotates, by steel ball 73 by transmission of power to spherical shell 72, when steel ball 73 is along rolling path rolling, the angle of the axis of inner race 71 and the axis of spherical shell 72 can be regulated.
Wherein, the two ends of output shaft 3 are fixedly connected with the inner race 71 of rzeppa joint 7 respectively, the outboard end of the cutterhead installing hole of cutterhead 2 and the spherical shell 72 of rzeppa joint 7 are bolted to connection, the medial extremity of cutterhead installing hole is rotated by deep groove ball bearing 5 and is installed on the outer peripheral face of bearing block 62, bearing block 62 is enclosed within output shaft 3 and one end and is fixed on end cap 61, the outboard end of bearing block 62, relative to the downward-sloping setting of output shaft 3, makes the lower end of cutterhead 2 slope inwardly.
For convenience of manufacturing and installing, in the present embodiment, bearing block 62 and end cap 61 are welded as a whole, and form weldment 6.
When using ditching machine trench digging, ridging, the input of transmission case is connected with power set, power gear 4 by transmission of power to output shaft 3, the power that the two ends of output shaft 3 export passes to cutterhead 2 by rzeppa joint 7, realize the varied angle transmission of power between output shaft 3 and cutterhead 2, cutterhead 2 drives cutter tooth 21 to rotate trench digging; Because the lower end of two cutterheads 2 all slopes inwardly, the cutter tooth 21 of two cutterhead lower ends is drawn close very near, thus dish out being gathered in casing 1 soil that is anterior and bottom to both sides, thus the front portion of casing 1 and bottom can not accumulate soil, interference can not be caused to moving ahead of ditching machine, ditching machine passes through smooth and easy, ditches without hindrance, improves the trench digging efficiency of ditching machine.
In sum, furrowing machine knife disc assembly of the present utility model realizes the varied angle transmission of power between output shaft and cutterhead by rzeppa joint, cutterhead lower end slopes inwardly setting, avoid soil anterior and bottom accumulation at the casing of transmission case, improve front line speed and the trench digging efficiency of ditching machine.
