Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural equipment, and particularly relates to an adjustable trench subsoiling integrated machine for use under straw mulch. Background Art

[0002] Subsoiling the land, also known as deep tillage of the land, refers to a tillage technique in which a subsoiling implement is towed by a tractor to loosen the soil, break the plow sole, improve the plow layer structure, and enhance the soil's water storage, moisture conservation, drought resistance, and waterlogging drainage capabilities. Carrying out subsoiling operations is beneficial to the growth of crops and is one of the important means to increase crop yields;

[0003] During subsoiling, the soil layer is not overturned. When operating, due to the presence of a large amount of stubble, straw, weeds, etc. on the ground surface, as the subsoiling tool moves, the straw in front of it will gradually accumulate to form a straw bale. As time goes by, the straw bale becomes larger and larger, bringing resistance to the advancement of the subsoiling implement, causing significant power loss. It is necessary to stop the machine for manual cleaning of the straw bale at regular intervals, which will also affect the work efficiency. Summary of the Invention

[0060] During operation, the tractor drives the subsoiling tool 10 to move forward uniformly in a straight line at a predetermined depth in the soil, forming grooves, loosening the soil, breaking the plow sole, improving the tillage layer structure, and enhancing the soil's water storage, moisture retention, drought resistance, and waterlogging drainage capabilities.

[0061] Furthermore, the groove and the subsoiling component further include a hole structure, and the hole structure includes:

[0062] A rotating shaft 13 rotatably installed at the lower part of the side wall of the subsoiling tool 10, which can be rotatably installed through bearings and bearing seats;

[0063] A power mechanism for driving the rotating shaft 13 to rotate. In this embodiment, the power mechanism includes a first power motor and a belt drive structure 12. The first power motor is fixed to the upper part of the subsoiling tool 10 and can be fixed by bolts. The first power motor is drivingly connected to the rear end of the rotating shaft 13 through the belt drive structure 12. An outer shell can be provided outside the rear end of the rotating shaft 13 and the pulley to play a protective role, and the outer shell can be detachably fixed to the subsoiling tool 10 by screws;

[0064] Multiple soil-breaking plates 17 circumferentially and spacedly installed at the front end of the rotating shaft 13, with the middle of the soil-breaking plates 17 hinged to the front end of the rotating shaft 13;

[0065] An adjusting rod 14 rotatably installed inside the rotating shaft 13 and coaxial with it. One end of the adjusting rod 14 extends out of the rear end of the rotating shaft 13. The adjusting rod 14 is provided with an external thread section 15. An internal thread sleeve 16 is threadedly connected to the external thread section 15. Multiple connecting rods 20 are circumferentially and spacedly hinged to the internal thread sleeve 16. The connecting rods 20 correspond to the soil-breaking plates 17 one by one, and the end of the connecting rod 20 away from the internal thread sleeve 16 is hinged to the corresponding soil-breaking plate 17;

[0066] During operation, the power mechanism drives the rotating shaft 13 to rotate, the rotating shaft 13 drives the multiple soil-breaking plates 17 to rotate synchronously, the soil-breaking plates 17 break the soil, and along with the traction of the tractor, continuous holes are formed underground, improving the soil's water storage and promoting drainage.

[0067] Preferably, the hole structure further includes:

[0068] A soil-breaking head 18, one end of which penetrates into the rotating shaft 13 from the front end of the rotating shaft 13.

[0072] Specifically, the back-pushing component includes:

[0073] A fourth hydraulic rod 32 vertically fixed on the frame 5, which can be fixed by bolts. The telescopic end of the fourth hydraulic rod 32 is fixed with a housing 33, which can be fixed by welding;

[0074] Two spur gears 40 symmetrically and rotatably installed in the housing 33 and meshing with each other. A third stepping motor (not shown in the figure) for driving any one of the spur gears 40 to rotate is fixed on the housing 33;

[0075] A pin shaft eccentrically fixed on each spur gear 40. The two pin shafts are symmetrically arranged. A movable rod 34 is respectively provided on the front side of each spur gear 40.

When the two mounting sleeves 36 approach, through the screw fit between the outer screw rod 41 and the driving sleeve 42, it drives the driving sleeve 42 to rotate. The driving sleeve 42 drives the connecting rod 30 to move further towards the middle, so that finally the two movable plates 37 are as close as possible. Then the third stepping motor drives the spur gear 40 to continue rotating 180 degrees. During this process, the pin shaft will drive the movable plate 37 and the rollers 38 to gradually move upward and separate from the ground and then move downward to contact the ground through the movable rod 34 and the mounting sleeve 36. At the same time, the two mounting sleeves 36 move away, the two movable plates 37 and the rollers 38 on them move away, and under the action of the outer screw rod 41, the driving sleeve 42 drives the connecting rod 30 back to its original position, and the movable plate 37 and the rollers 38 are reset.
