Description

Suspension type rice cultivator
Technical field
The utility model relates to a kind of cultivating tillage equipment, particularly is applicable to the intertill and clean tillage in the Rice Production process, the mounted cultivator tool of the operation of loosening the soil, and belongs to agricultural machinery technological field.
Background technology
In the Rice Production process, the intertill and clean tillage cargo handling operation that is absolutely necessary.Traditional herbicidal methods all is to adopt manual pulling out, and also has the simple manpower of use to weed and weeds and loosen the soil device, and each delegation shuttles in the field, and labour intensity is very big.Invented hand steered walk-behind type paddy-field extirpator afterwards, it is rolled spin and transfers weeding by reduction box, drive chain case transmission weeding cutter by small gasoline engine, and working width 2~3 row are though this machine can be realized the operation of mechanization intertill and clean tillage, improve operating efficiency, alleviated people's labour intensity widely.But the weak point that this machine exists has, the one, and operating personnel walk in the ranks, operate machines while walking, and are more arduous.The 2nd, can not remove the weeds of paddy rice near rice seedling; The 3rd, tilling depth is restive, and the Ex-all rate of weeds is not high.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency that exists at existing paddy rice extirpator, propose a kind ofly to match with the four-wheel working in paddy field, operate light, can remove near the weeds rice seedling, can control the suspension type rice cultivator of tilling depth automatically.
In order to solve above-mentioned technical problem, suspension type of the present utility model rice cultivator comprises frame, transmission case, left and right drive chain case, and the weeding rotary blade rolls, and also comprises left and right swing arm, interlinked mechanism, swing mechanism and weeding pawl.The power shaft of described left and right drive chain case is connected with the horizontal output shaft of transmission case, and described weeding rotary blade rolls the output shaft fixed connection with left and right drive chain case; Described left and right swing arm constitutes parallelogram lindage by rocking bar and frame respectively, and both interconnect by interlinked mechanism, and are connected with the vertical output axle of transmission case by swing mechanism, and described weeding pawl and left and right swing arm are connected.
The interlinked mechanism of aforesaid suspension type rice cultivator can be a center rocking bar interlinked mechanism, and the rocking bar and the frame of described center rocking bar interlinked mechanism are hinged, and its two ends are hinged by connecting rod and left and right swing arm respectively; Swing mechanism can be a crank-swinging mechanism, and the crank of described crank-swinging mechanism and the vertical output axle of transmission case are connected, its crank pin be installed in swing arm on the left swing arm and constitute and be slidingly connected.
Further improvement of the utility model is, also comprise the tilling depth adjusting device, it is made up of four-bar mechanism and skid, and the rocking bar and the frame of described four-bar mechanism are hinged, described skid and described rocking bar are hinged, and the hydraulic control steel wire cable of regulating tilling depth is installed on the upper connecting rod of described four-bar mechanism.
Compared with prior art, suspension type of the present utility model rice cultivator is supporting with sitting type four-wheel working in paddy field, tractor driver's operation that is seated, and labour intensity is low; Roll both sides at rotary blade and set up swing type weeding pawl, enlarged effective weeding scope of cultivator, minimizing is balked; Set up the tilling depth governor motion, improved weeding, the effect of loosening the soil.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of transmission case among Fig. 1.
Fig. 4 is left and right swing arm and a link gear vertical view among Fig. 2.
Embodiment
Shown in Fig. 1~4, the suspension type rice cultivator of present embodiment, mainly roll 3 by frame 5, transmission case 1, left and right drive chain case 2,13, weeding rotary blade, compositions such as left and right swing arm 9,12, weeding pawl 4, this machine frame 5 is suspended on the sitting type four-wheel working in paddy field by connecting rod, and the power input shaft 18 of transmission case 1 is connected with the power take-off of workover rig.The left end of the horizontal output shaft 14 of transmission case is connected with the power shaft of left chain case 2, and right-hand member is connected with the power shaft of right chain case 13 by power transmission shaft 10, and the weeding rotary blade rolls 3 and the output shaft fixed connection of left and right drive chain case 2,13; Left and right swing arm 9,12 constitutes parallelogram lindage by rocking bar 22 and frame 5 respectively, and both interconnect by interlinked mechanism 11, and are connected with the vertical output axle 17 of transmission case by swing mechanism, and weeding pawl 4 is connected with left and right swing arm 9,12.
From Fig. 3, Fig. 4 as can be seen, interlinked mechanism 11 is a center rocking bar interlinked mechanism, the rocking bar 21 of described center rocking bar interlinked mechanism is hinged with frame 5, and its two ends are hinged with an end of connecting rod 20 respectively, and the other end of connecting rod 20 is hinged with left and right swing arm 9,12 respectively; The swing mechanism that drives left and right swing arm 9,12 is a crank-swinging mechanism, and the crank 16 of crank-swinging mechanism is connected with the vertical output axle 17 of transmission case, and its crank pin 15 is slidingly connected by roller and swing arm 19 formations that are installed on the left swing arm 9.Obviously when the vertical output axle 17 of transmission case rotates, just drive left and right swing arm 9,12 and do transverse movement, the weeding pawl just can be removed the weeds near rice seedling.
The dark adjusting device of this tractor-ploughing is made up of four-bar mechanism 7 and skid 6 as can be seen from Figure 1, and the rocking bar and the frame of four-bar mechanism 7 are hinged, and skid 6 is hinged with rocking bar, and the hydraulic control steel wire cable 8 of regulating the working in paddy field tilling depth is installed on the upper connecting rod of four-bar mechanism 7.Skid 6 is attached on the surface, paddy field and moves ahead during operation, when the face of land just changes, is subjected to the control of this tilling depth adjusting device just can realize the automatic adjusting of working in paddy field tilling depth, thereby keeps the tilling depth unanimity, improves the Ex-all rate of weeds.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
