Existing dual-shaft deep tillers are prone to damage to their tillage mechanisms when encountering large rocks, which affects tillage efficiency.

Method used

The vertical deep tillage machine with hydraulic rock-avoidance and tillage depth adjustment uses a pressure sensor to detect the pressure of the drill bit. When the pressure exceeds the set pressure, the telescopic rod drives the drill bit to move upward, and the anti-collision component makes the drill bit avoid the rocks. The braking mechanism then quickly stops the rotation.

Benefits of technology

It effectively prevents drill bits from colliding with rocks, protects equipment, and improves farming efficiency.

Description

Technical Field

[0001] This invention relates to the field of deep tillage technology, specifically to a hydraulic rock-avoiding vertical deep tillage machine with adjustable tillage depth. Background Technology

[0002] A deep tiller is an agricultural machine primarily used for cultivating soil, especially loosening, turning, and breaking up the topsoil in deep soil layers to improve soil aeration and permeability, thereby promoting plant root growth. It is widely used in agricultural production fields such as farmland, orchards, and tea plantations, and is particularly suitable for areas with hardened or heavy soils. It effectively improves soil structure. Research on deep tillers in universities has broad academic value and application prospects, promoting the advancement of agricultural mechanization and making positive contributions to achieving green development and intelligent transformation in agriculture.

[0003] The publication number CN209609120U discloses a dual-shaft deep tillage machine, including a three-point suspension mechanism, a gearbox, a transfer case, a first vertical shaft deep tillage mechanism, and a second vertical shaft deep tillage mechanism. The gearbox is mounted on the top of the transfer case, and the power output shaft at the bottom is connected to both the first and second vertical shaft deep tillage mechanisms. The first and second vertical shaft deep tillage mechanisms have the same external dimensions, equal rotation speeds, opposite rotation directions, and are arranged perpendicularly to the machine's travel direction. The first and second vertical shaft deep tillage mechanisms include a hexagonal square tube shaft, a cutter holder, a spiral auger, and a rotary cutter. The hexagonal square tube shaft passes through the center of the spiral auger and is connected by electric welding. Multiple cutter holders are welded onto the spiral auger, and rotary cutters are mounted on the cutter holders.

[0004] However, when the aforementioned dual-shaft deep tiller is in use, because the first and second vertical shaft deep tillage mechanisms are fixedly installed on the power output shaft, when there are large stones in the soil being tilled by the deep tiller, the deep tillage mechanism will collide with the stones, causing damage to the deep tillage mechanism and affecting the tillage efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical deep tillage machine with hydraulic rock-avoidance and adjustable tillage depth to solve the problems mentioned in the background art.

[0019] Preferably, when the pressure sensor detects that the pressure on the drill bit exceeds the limit pressure, the trigger motor drives the trigger leg to rotate along the slide groove, so that the trigger leg presses the bonding plate into the retractable groove, so that the trigger plate of the trigger leg is aligned with the trigger groove, the pull spring pulls the sliding box, pulls the drill bit off the ground, so that the brake plate is in contact with the abrasive disc, and the drill bit stops rotating.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention utilizes a pressure sensor and a telescopic rod. When the drill bit encounters a rock, the pressure sensor detects an increase in pressure, and the telescopic rod causes the drill bit to retract, moving it upwards to avoid the rock. Furthermore, the anti-collision component ensures that if the drill bit suddenly impacts a rock, a return spring will cause the drill bit to move rapidly, preventing damage.

One end of the second buffer spring 33 is fixedly connected to the mounting plate 31 by means of welding, etc., and the other end of the second buffer spring 33 is fixedly connected to the inner wall of the fixed box 11 by means of welding, etc. By setting the stop plate 32 and the second buffer spring 33, the box cover 2 moves to the point where the grinding disc 29 is in contact with the stop plate 32. At the same time, the mounting plate 31 moves to provide buffering, so that the drill bit 5 stops rotating quickly.

[0039] Working principle: In use, the fixing box 11 is installed on a traction platform such as a tractor by means of bolts and other connecting parts. The drill bit 5 is used to insert into the ground and is dragged by the traction platform to deeply cultivate the ground. When the pressure sensor 6 detects that the pressure on the drill bit 5 exceeds the set pressure, the telescopic rod 4 retracts, thereby driving the drill bit 5 to move upward and avoid stones. When the pressure sensor 6 detects that the pressure on the drill bit 5 exceeds the limit pressure, the trigger motor 17 drives the trigger leg 20 to rotate along the slide groove 15, so that the trigger leg 20 presses the bonding plate 25 into the retracted groove 23, so that the trigger plate 19 of the trigger leg 20 aligns with the trigger groove 16. The pull spring 14 pulls the sliding box 8, pulling the drill bit 5 off the ground, so that the brake plate 32 is in contact with the abrasive disc 29, so that the drill bit 5 stops rotating quickly, preventing the drill bit 5 from bending after colliding with stones and preventing the drill bit 5 from damaging other parts.
