The tops of the strain bin a and the driving cavity b are respectively provided with an upper cover 50 which is in rotary connection fit with the strain bin a and the driving cavity b.
The following describes the application method and principle of the technical scheme in the specific embodiment with reference to the drawings:
firstly, the case 1 is in butt joint with a tractor, then the whole transmission device in the invention is all towed into a farmland needing stubble cleaning, then the motor 13 is started, the motor 13 drives the driving shaft 12 to rotate in the rotating process, the driving shaft 12 drives the driven bevel gear 42 to rotate through the driving bevel gear 41 respectively in the rotating process, the crank 15 and the first shaft seat 17 drive the first connecting rod 18 to reciprocate back and forth, and finally the stubble cleaning tool rest is driven to rotate;
then, according to the requirements of the field, the hand wheel 371 is rotated to drive the screw rod 37 to rotate, the screw rod 37 drives the square tube 38 to linearly lift along the square hole on the square tube seat 39 in a spiral matching mode in the rotating process, so that the purpose of adjusting the shovel depth of the shovel blade 6 is realized by adjusting the horizontal height direction between the universal wheel 40 and the shovel blade 6, as is well known, the ground in the field is uneven, as the whole depth-fixing frame 30 is in rotary connection and matching with the third shaft seat 32 through the second connecting rod 31, and the bottom of the depth-fixing frame 30 is in rotary connection and matching with the fourth shaft seat 34 through the third connecting rod 33, the universal wheel 40 serving as a guide wheel can effectively drive the cutting edge part of the whole shovel blade 6 to be always attached to the undulating ground for shovel soil, and therefore, the balancing weight is also preferably arranged on the depth-fixing frame 30;
the lifted ground with the soybean straw and hardened enters the stubble cleaning bin c through the feeding hole d by the guide of the soil shoveling knife 6, and the soybean straw on the ground encounters the first cutter disc 7 and the second cutter disc 8 which rotate at high speed and is crushed by the blade 11 to the ground, so that the crushed soybean straw can be decomposed in soil rapidly, as is well known, the speed of straw decomposition is related to the crushing degree of the straw;
in the rotating process of the driven bevel gear 42, the double chain wheels 44 are driven to rotate through the gear shafts 43, the rotation of the double chain wheels 44 respectively drives the first driven chain wheels 46 on the rotary tillage mechanism 100 to rotate through the first chains 45, so that the purpose of driving the rotary tillage mechanism 100 to rotary tillage is achieved, and the second driven chain wheels 48 are driven to rotate through the second chains 47, so that the purpose of driving the driving roller 4 to drive the conveying belt 3 to convey towards the direction of the discharge hole e is achieved;
after the crust is scooped up, rotary tillage is carried out by means of the conventional rotary tillage mechanism 100 to form a 20-40cm cultivation layer, when the cultivation layer is required to be described, the cultivation layer is free of any straw, the broken cultivation layer only contains fibrous root systems mixed with the previous crop of soybeans, the influence on the growth of the next crop of spring soybeans is almost negligible, and then a groove is formed in the broken cultivation layer by the conventional ditching plow 200;
the first connecting rod 18 drives the sliding block 20 and the rack 22 to reciprocate along the length direction of the sliding groove by the second shaft seat 19 which is in rotary connection with the first connecting rod 18 in the reciprocating process, the rack 22 drives the toothed column 23 to rotate in a meshing and matching way in the reciprocating process, strain particles stored in the strain bin a fall onto the wave wheel 27 through the toothed column 23 and a hollow pipeline in the shaft tube 24, and in order to improve the mobility of the strain particles near the shaft disc 25, the upper top surface of the shaft disc 25 is preferably provided with threads which rotate in a plane, so that the strain particles near the shaft disc 25 flow towards the pipeline in the center of the shaft disc 25, and finally the strain particles are uniformly scattered on straws on the ground in the whole stubble cleaning bin c by the rotation of the wave wheel sheet 28;
the crust after straw crushing and strain particle spraying is discharged from a discharge hole e through the conveying of a conveying belt 3 and falls into a groove formed by a ditching plow 200, and finally the current crust is buried under a new plough layer together with straw powder and degraded strain particles through the earthing of an earthing furrow 300;
the stubble cleaning mechanism of the transmission structure can completely overcome the influence of the soybean straw degradation and lower decomposition speed on the development of root systems of the next winter wheat in the initial period of 2-3 months through the actual operation of the agricultural machine, the winter wheat root systems in the initial period of 2-3 months are widely distributed in 15-25cm cultivation layers, so that the soybean straw stubble layers deeply buried under the cultivation layers are not contacted at all in the initial period of 2-3 months of winter wheat growth, the winter wheat root systems continue to grow downwards and tillering after the decomposition of the straw stubble deeply buried under the cultivation layers for 2-3 months is finished, no straw is left under the cultivation layers at the moment, and the winter wheat root systems continue to grow downwards and tillering in the coming year which are not hindered.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; while the invention has been described in detail with reference to the foregoing embodiments, it will be appreciated by those skilled in the art that variations may be made in the techniques described in the foregoing embodiments, or equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
