Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a rotary tiller blade shaft with good tillage effect. Background Technology

[0002] Rotary tillers are tillage machines that work in conjunction with tractors to perform tilling and harrowing operations. They are widely used because of their strong soil-breaking ability and the ability to flatten the soil surface after tilling. They can also chop up stubble buried below the surface, making it easier for seeders to work and providing a good seedbed for later sowing. The rotary tiller's blade shaft is one of the core components of the rotary tiller. It is generally made of high-quality alloy steel or high-strength steel. These materials have high strength and wear resistance and can withstand complex loads such as soil resistance, stone impacts, and centrifugal force generated by the rotation of the blades during rotary tilling.

[0003] Judging from the shape and structure of the blades, the design of existing rotary tillers may not have fully considered the soil breaking mechanics principles under different soil conditions. The angle and curvature of some blades are poorly designed, and they cannot form an effective cutting angle when in contact with the soil, thus failing to fully utilize the blades' soil breaking ability. At the same time, various weeds often grow in farmland, and the blades of existing rotary tillers can easily become entangled with these weeds during rotation. In addition, there may be other foreign objects in the farmland, such as plastic film fragments and crop straw residues. During rotary tillage, these foreign objects are drawn into the soil between the blades as the blades rotate, further exacerbating the entanglement. Furthermore, while the rotary tiller transmits power to the cutter shaft via the transmission system, driving the blades to rotate, the existing transmission system and blade combination may exhibit inconsistencies in power transmission and soil fragmentation control. When the blades rotate at high speed to shred the soil, the inertia of the power, along with the blade angle and rotational speed, causes the fragments to be irregularly flung backward. These fragments accumulate on the tilled surface, forming uneven mounds and pits. This not only affects the flatness of the farmland surface but also causes inconvenience for subsequent agronomic operations such as sowing and irrigation.

[0004] Therefore, there is an urgent need to provide a rotary tiller cutter shaft with good tillage effect to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rotary tiller blade shaft with good tillage effect.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a rotary tiller blade shaft with good tilling effect, including a front frame, a blade shaft rotatably connected inside the front frame, and multiple mounting mechanisms fixedly installed on the surface of the blade shaft, the mounting mechanisms being used to install the tilling blades, and further including;

[0007] The installation mechanism is detachably equipped with a straight blade, which is used for breaking ground.

[0008] The mounting mechanism is equipped with a detachable curved blade, which is used for rotary work.

[0009] The present invention is further configured such that: a traction frame is fixedly installed on the surface of the front frame, and a soil retaining plate is fixedly installed on the surface of the front frame.

[0010] Through the above technical solution, the towing frame is used to connect with the tractor or other drive mechanism, and the retaining plate plays a blocking role to prevent some of the broken soil from being thrown backward during the turning process, which would cause the land to be uneven.

[0011] The present invention is further configured such that: the mounting mechanism includes mounting blocks, and multiple mounting blocks are configured, the mounting blocks are fixedly mounted on the surface of the cutter shaft and are arranged in a ring of four mounting blocks.

[0012] The above technical solution uses mounting blocks for mounting straight and curved blades. Each group of mounting blocks consists of four blocks, used to mount two straight blades and two curved blades respectively, which makes the spinning process smoother and improves the spinning effect.

[0013] The present invention is further configured such that: an installation groove is provided inside the installation block, a spring is fixedly installed inside the installation groove, a lifting plate is fixedly installed at the other end of the spring, and the lifting plate is slidably connected inside the installation groove.

[0014] With the above technical solution, the straight blade and the curved blade are fixedly installed inside the mounting slot by bolts. When the straight blade and the curved blade are worn, the spring and the lifting plate will lift the straight blade and the curved blade from inside the mounting slot, making it convenient for the staff to pick them up.

[0015] The present invention is further configured such that: the mounting block, the straight blade and the curved blade are all provided with screw holes, and bolts are threaded into the screw holes.

[0016] The above technical solution allows the straight and curved blades to be fixed inside the mounting block by the cooperation of bolts and screw holes. When replacing the straight and curved blades, simply loosen the bolts and remove the blades.

[0017] The present invention is further configured such that: each set of mounting blocks is provided with two straight blades and two curved blades, the straight blades and curved blades are staggered, and a curved blade is provided between two adjacent straight blades.

[0018] Through the above technical solution, the advantage of straight blades is that they break through the soil directly and are not easily entangled with weeds and other foreign objects. The straight blades and curved blades are distributed alternately, so that they are not easily blocked by bricks or tiles, reducing rotational resistance and improving the efficiency of turning the soil.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model is equipped with straight blades and curved blades. The advantage of straight blades is that they break the soil directly and are less likely to get tangled in weeds or other foreign objects. When encountering foreign objects, straight blades will directly throw them out. At the same time, the surface of straight blades is not easily contaminated with soil. The straight and curved blades are distributed alternately, so that bricks or tiles are not easily blocked between them, reducing rotational resistance and improving tillage efficiency. The straight and curved blades work together to prevent soil from being thrown backward. The ground after rotary tillage is flat. Foreign objects will not get stuck between the blade shaft and the straight and curved blades, which can ensure the continuity of tillage work and save time. Attached Figure Description
