Description
Technical field
The utility model relates to constructional engineering machinery field, is specifically related to a kind of spiral rotating milling cutter device.
Background technology
Land leveller is plant equipment for clearing up soil, smooth, is widely applied in the engineering constructions such as surface structures, and land clearing is smooth is the necessary condition that modern agriculture engineering and most ground engineering construction are constructed.The main distinction of land leveller is: the quantity of scraper have hilted broadsword formula and multiple-pin point; The control form of scraper is different, but all should possess lifting, inclination, revolution and overhanging function; The position that scraper is contained in wheel shaft before and after driving device is also different, is divided into preposition, rearmounted etc.This based on the scraper land leveller of rectangular bar shaped curved slab, be mainly used to the shaping construction of large area formation of land and highway, and there is the problem that vibration is comparatively large, stability is not high in existing scraper, especially in the occasion that the scope of operation is narrow, cannot ensure the smooth precision in soil.
Summary of the invention
(1) technical problem that will solve
The technical problems to be solved in the utility model how to make the milling cutter device in level land device in the process of level land, vibrate reduction, stability raising, thus guarantee the smooth precision in soil.
(2) technical scheme
For solving the problems of the technologies described above, a kind of spiral rotating milling cutter device being provided, comprising vertical shaft, around the helical blade that described vertical shaft left-right rotary is positioned opposite, and be fixed on the cutter blade of helical blade cylindrical.
Preferably, described cutter blade being circumferentially uniformly distributed at described helical blade.
Preferably, the radial direction angle of the rake face of described cutter blade and the spiral cylindrical of helical blade is 12 ゜-17 ゜.
Preferably, the radial direction angle of the rake face of described cutter blade and the spiral cylindrical of helical blade is 15 ゜.
Preferably, the tangent line angle of the rear knife face of described cutter blade and the spiral cylindrical of helical blade is 18 ゜-23 ゜.
Preferably, the rear knife face of described cutter blade and the spiral cylindrical tangent line angle of helical blade are 20 ゜.
Preferably, the quantity of described cutter blade is 3-8 sheet.
(3) beneficial effect
Spiral rotating milling cutter device of the present utility model, helical blade left-right rotary is positioned opposite, relative motion, cutter blade is circumferentially uniformly distributed at helical blade, rotary cutting is native relatively, active force when this ensure that two groups of spiral rotating milling cutter devices cutting ground can be cancelled out each other, reduce vibration, improve stability, ensure that the smooth precision of foundation trench.
Accompanying drawing explanation
Fig. 1 is the structural representation of the spiral rotating milling cutter device according to the utility model embodiment;
Fig. 2 is the angle schematic diagram of the cutter blade of spiral rotating milling cutter device according to the utility model embodiment.
Wherein, 1: vertical shaft; 2: helical blade; 3: cutter blade.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is done into a detailed description.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model provides a kind of spiral rotating milling cutter device, comprises vertical shaft 1, around the helical blade 2 that vertical shaft 1 left-right rotary is positioned opposite, and being fixed on the cutter blade 3 of helical blade 2 cylindrical, cutter blade 3 is circumferentially uniformly distributed helical blade 2.As shown in Figure 2, the rake face of cutter blade 3 and the radial direction angle of spiral cylindrical are 12 °-17 °, ensure that blade smooth working friction, and the angle of rear knife face and helical blade cylindrical tangent line is 18 ° of-23o, reducing the wearing and tearing because causing with soil layer friction, making cutting soil process smooth smoothly.In the present embodiment, the radial direction angle of the preferred rake face of cutter blade 3 and the spiral cylindrical of helical blade 2 is 15 ゜, and the rear knife face of cutter blade 3 and the spiral cylindrical tangent line angle of helical blade 2 are 20 ゜, and the quantity of cutter blade 3 is 6.Simultaneously in order to increase the rub proofness of cutter blade, while selecting wear-resisting steel, Wear-resistant Treatment being carried out to blade face, having improved its application life.
The spiral rotating milling cutter device typical case that the utility model provides is applicable to level land device, usual spiral rotating milling cutter device is connected with gear reduction box by its vertical shaft 1, two, left and right spiral rotating milling cutter device is by the external gear pump transmission of two identical numbers of teeth in gear reduction box, thus about being formed, two spiral rotating milling cutters relatively rotate with identical angular velocity.Due to the lead angle of helical blade 2 itself, there is again the function of centrifugal soil, guarantee that level land device can normally steadily advance.Helical blade 2 left-right rotary is positioned opposite, relative motion, and cutter blade 3 is being circumferentially uniformly distributed of helical blade 2, relatively rotary cutting soil.Therefore according to mechanics principle, active force during two groups of spiral rotating milling cutter devices cutting ground can be cancelled out each other, and reduces vibration, improves stability, ensure that the smooth precision of foundation trench.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
