Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a stubble-chopping rotary tiller capable of preventing congestion and entanglement. Background Art

[0002] The stubble rotavator is mainly powered by power equipment such as tractors. Its working parts are a set of high-speed rotating blades, which are driven by power and rotate at a certain speed to cut into the soil. During the rotation process, the blades break up and stir the soil, and chop the crop residues to mix them fully with the soil.

[0003] In the prior art, a large amount of stubble enters the rotary tiller at the same time during the rotary tillage process, which easily causes congestion. Some of the crop stubble has strong toughness and is not easy to be cut off, and is easy to be entangled in the cutter and other parts. If it is not cleaned up in time, the congestion and entanglement will become more and more serious, which will cause the operator to stop the tractor and other power equipment, and then manually clean the stubble or debris entangled on the rotary tiller.

[0041] When the two sets of fixing plates 31 are folded, the two sets of fixing plates 31 are folded together through the two sets of connecting members 14 and the two sets of No. 1 recesses 15 .

[0042] Embodiment 4: Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the fixing mechanism 5 includes two groups of cylinders 51 and four groups of long bolts 52.

[0044] The working principle of the present invention is as follows: when in use, first, the mounting frame 1 is installed on the tractor, and the power end of the power system is fixed to the power input end of the gearbox 22. After that, by synchronously starting the four groups of No. 1 cylinders 33, the extended ends of the four groups of No. 1 cylinders 33 drive the two groups of fixed plates 31 to move through the four groups of No. 3 recesses 34, during which the tail ends of the extended ends of the four groups of No. 1 cylinders 33 move inside the four groups of No. 3 recesses 34 and the two groups of No. 2 recesses 32, respectively, and the two groups of fixed plates 31 drive the four groups of movable seats 36 to move on the outer walls of the four groups of movable blocks 35, respectively. At the same time, the two groups of fixed plates 31 will also drive the two groups of No. 2 rods 25 to move together through the two groups of matching plates 24, and the two groups of No. 2 rods 25 drive several groups of rotary tillage assemblies 26 to move, thereby extending the two groups of fixed plates 31;

[0045] Then, by moving the two groups of cylinders 51 on the outer wall of the No. 1 rod 23, and moving a part of the two groups of cylinders 51 to the outer walls of the two groups of No. 2 rods 25, the four groups of long bolts 52 are inserted into the four groups of No. 1 holes 54 and the four groups of No. 2 holes 55 one by one, and then the four groups of long bolts 52 are rotated one by one, so that the four groups of long bolts 52 are respectively rotated on the internal threads of the four groups of threaded seats 53, and then the two groups of cylinders 51 can be fixed on the two ends of the No. 1 rod 23 and the outer walls of the two groups of No. 2 rods 25 respectively;

[0046] Afterwards, according to the rotary tillage depth, the angles of several groups of barb blocks 49 are adjusted, and the four groups of No. 2 cylinders 42 are started synchronously. The extended ends of the four groups of No. 2 cylinders 42 push the four groups of No. 2 concave seats 44 to move, wherein two groups of No. 2 concave seats 44 push the long rods 47, and the other two groups of No. 2 concave seats 44 push the two groups of short rods 48 to move, respectively. Since the long rod 47 and the two groups of short rods 48 rotate inside the six groups of limit seats 46, the extended ends of the four groups of No. 2 cylinders 42 will push the long rod 47 and the two groups of short rods 48 to move through the four groups of No. 2 concave seats 44, and at the same time, one end of the four groups of No. 2 cylinders 42 rotates inside the four groups of No. 1 concave seats 41, respectively, so that the long rod 47 and the two groups of short rods 48 rotate inside the six groups of limit seats 46, and the long rod 47 and the two groups of short rods 48 will drive several groups of barb blocks 49 to move, so that the angles of several groups of barb blocks 49 can be adjusted;

[0047] Finally, the tractor drives the rotary tiller to operate and provides power for the gearbox 22. The gearbox 22 drives the two groups of No. 1 rods 23 to rotate. The No. 1 rod 23 drives the two groups of No. 2 rods 25 to rotate through the fixing mechanism 5, so that the No. 1 rod 23 and the two groups of No. 2 rods 25 rotate inside the six groups of matching plates 24 respectively. At the same time, the No. 1 rod 23 and the two groups of No. 2 rods 25 drive several groups of rotary tillage assemblies 26 to rotate, so as to facilitate several groups of rotary tillage assemblies 26 to rotary till the ground. With the cooperation of several groups of barb blocks 49, when several groups of rotary tillage assemblies 26 are rotary tilling, when they rotate to several groups of barb blocks 49, the stubble or debris entangled on the surface of several groups of rotary tillage assemblies 26 will be blocked by several groups of barb blocks 49, and several groups of rotary tillage assemblies 26 will continue to rotate, and the stubble or debris will fall off from the outer wall of several groups of rotary tillage assemblies 26, so that the stubble or debris can be blocked during rotary tillage, which can prevent the stubble or debris from being entangled on the rotary tillage assemblies 26.
