Description

Technical Field

[0001] The utility model belongs to the technical field of scarifiers, in particular to an agricultural soil improving scarifier. Background Art

[0002] A scarifier is a machine used in earthmoving construction to loosen hard soil, frozen soil, old roads, and even medium-hard rock using toothed ripper blades. Depending on how the ripper is connected to the tractor, it can be towed or mounted. The ripper utilizes the tractor's traction and the weight of the ripper to drive the tines into the soil, loosening the hard soil and leaving a loosened area behind. It is often used for pre-scarring operations before bulldozers or scrapers. Compared to traditional drilling and blasting methods, it offers advantages such as simplified construction techniques, reduced equipment, higher productivity, and improved safety, making it a key preparatory tool for earthmoving projects.

[0003] The top of the motor is connected to the transmission shaft by a movable frame, and the bottom of the motor is connected to the transmission shaft by a movable frame.

[0004] The tiller shovels the ground with a high-speed rotating tiller to loosen the soil. However, the tiller can only loosen the shallow soil layer and cannot loosen the deeper soil layer. This cannot meet the cultivation environment of different crops. In order to solve the above problems, an agricultural soil improvement tiller is proposed. Utility Model Content

[0018] Through the above technical solution, when an emergency stop is required, the handle can be pulled outward, and the handle is subjected to force to drive the pull rod and the locking block to move outward. During the movement, the locking block contacts the first rotating shaft, thereby stopping the first rotating shaft from rotating to achieve an emergency stop.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention provides an agricultural soil improvement loosening machine.

[0020] When soil loosening operation is required, the frame is first moved to the area where the soil loosening is required, and the two first rotating shafts are driven to rotate through the gear commutator. During the rotation of the first rotating shaft, the connecting rod is driven to rotate, and the driving rod is coordinated with the transmission rod to move up and down through the connecting rod, so that the shovel teeth at its end continuously dig the soil, thereby loosening the deeper soil layer. During this process, the first transmission disc on the outer wall of the first rotating shaft rotates, and the second rotating shaft is driven to rotate through the first transmission disc and the second transmission disc. During the rotation of the second rotating shaft, the loosening knife on its outer wall rotates following its trajectory, and the shallow soil is loosened by the loosening knife, so that the device can loosen the deep and shallow soil layers at the same time.
