Description
Technical field
The utility model relates to the agricultural machinery field, particularly a kind of rear-mounted contrarotated rotary tiller.
Background technology
Rotovator is mainly used in little hoe grass, the nonirrigated farmland rotary tillage of work-yards such as farmland, orchard, vineland, dish canopy.Traditional rotovator is made up of gearbox, rotary tillage frame, main shaft, cutter and roller etc., its be by main frame through drive after the gearbox speed governing main shaft and on cutter rotate, thereby realize rotovator work.It is when work, and main shaft clockwise rotates and drives cutter and clockwise rotates.After this working method body is produced greatly kick, increase power consumption, make the facility oil consumption increase; And, its also have labour intensity greatly, shortcoming such as not easy to operate.
The utility model content
The purpose of this utility model provides a kind of rear-mounted contrarotated rotary tiller, and is low to overcome above-mentioned efficient, the shortcoming of operating difficulties.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of rear-mounted contrarotated rotary tiller, comprise gearbox, speed change lever, six square shafts, rotary blade, protective cover and rolling wheel, described gearbox is covert reduction box, gearbox is fixed in the middle of the protective cover, pull bar one end that is coupling on the forward and backward two side of protective cover, the described pull bar other end rolling wheel that is coupling; The forward and backward two side of described protective cover downside is fixed six square shaft two ends by bearing block, six square shafts middle part is with the counter-rotating drive, the some six sides covers of the outer socket of six square shafts, described six sides put by the fixing rotary tillage cutterhead of screw, and the rotary tillage cutterhead is provided with fixing hole, four orthogonal rotary tillage broach shells of welding on the rotary tillage cutterhead, rotary blade puts and is provided with fixing hole, the pommel of socket rotary blade in the rotary tillage broach shell, the pommel of rotary blade is provided with fixing hole, and described rotary blade middle part is provided with bending.
The beneficial effect of rear-mounted contrarotated rotary tiller described in the utility model is: adopt the counter-rotating working method, changed the cutter penetrating angle, improved garrulous soil rate and coverage rate, after be provided with rolling wheel, the land readjustment of rotary tillage is tangible, it is good to protect planting property, it is few to make that soil block flies upward, good environmental protection; Kick is changed over tractive force, reduced power consumption, make facility oil consumption minimizing, easy and flexible operation, labour intensity reduces.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of rear-mounted contrarotated rotary tiller described in the utility model;
Fig. 2 is the partial sectional view of rear-mounted contrarotated rotary tiller described in the utility model.
Among the figure:
1, gearbox; 2, speed change lever; 3, six square shafts; 4, six sides cover; 5, rotary blade; 6, protective cover; 7, rolling wheel; 8, counter-rotating drive; 9, rotary tillage cutterhead; 10, rotary tillage broach shell; 11, pull bar; 12, fixing hole; 13, bending.
Embodiment
Shown in Fig. 1-2, rear-mounted contrarotated rotation described in the utility model (counter-rotating) rotovator, comprise gearbox 1, speed change lever 2, six square shafts 3, rotary blade 5, protective cover 6 and rolling wheel 7, described gearbox 1 is covert reduction box, gearbox 1 is fixed in the middle of the protective cover 6, pull bar 11 1 ends that are coupling on the protective cover 6 forward and backward two sides, described pull bar 11 other ends rolling wheel 7 that is coupling; Before the described protective cover 6, back two side downside is fixed six square shafts, 3 two ends by bearing block, six square shafts, 3 middle parts are with counter-rotating drive 8, counter-rotating drive 8 is by the output wheel of connection gearboxes 1 such as belt, two six side's covers 4 of six square shafts, 3 outer sockets, on the described six sides cover 4 by the fixing rotary tillage cutterhead 9 of screw, rotary tillage cutterhead 9 is provided with fixing hole 12, four orthogonal rotary tillage broach shells 10 of welding on the rotary tillage cutterhead 9, rotary tillage broach shell 10 is provided with fixing hole 12, the pommel of socket rotary blade 5 in the rotary tillage broach shell 10, the pommel of rotary blade 5 is provided with fixing hole 12, described rotary blade 5 middle parts are provided with bending 13, described rotary blade 5, rotary tillage broach shell 10 and rotary tillage cutterhead 9 are fixed together by screw.
The operation principle of rear-mounted contrarotated rotation described in the utility model (counter-rotating) rotovator is, gearbox 1 is connected with hand steered mini-size tillage machine main frame, and main frame transmits power by gear, drives gearbox body work; Gearbox 1 changes the rotating speed of gear by speed change lever 2, thereby change the rotating speed of gearbox 1 output shaft, gearbox 1 output shaft rotates by counter-rotating drive 8 directions that belt drives on six square shafts 3, and pass through the six sides cover 4 of six square shafts, 3 its outer sockets of drive and go up fixing rotary blade 5 reverse (counterclockwise) rotation, rotary blade 5 rotates counterclockwise work, the back is opened in the soil rotary tillage throw to the back, improved garrulous soil rate and coverage rate from the front through protective cover 6; After the rolling wheel 7 established, the land readjustment of rotary tillage is tangible, and soil moisture conservation property is good.
