Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a paddy field wheel for a ride-on micro-tiller. Background Technology

[0002] A paddy field wheel is a mechanical accessory used to move and till paddy fields. It is commonly used on ride-on mini tillers, rotary tillers, or other farming machinery. The paddy field wheel is used to till the paddy field, loosen the topsoil, optimize the soil structure, and facilitate subsequent sowing and increase yield.

[0003] In related technologies, one can refer to the Chinese utility model patent with authorization announcement number CN202535687U, which discloses a paddy field wheel, including a rotating shaft, blades and blade nails. The tillage blades are installed on the rotating shaft, and the outer edge of the tillage blades has a soil-breaking groove. The blade nails are set on the blades and are connected to the edge of the soil-breaking groove to form an open structure of soil-breaking section that cannot accumulate soil. The opening direction of the soil-breaking section is opposite to the rotation direction of the tillage blades during operation.

[0004] During operation, the rotating shaft drives the blades and blade spikes to rotate. The blades till the soil in the paddy field and work with the soil-opening section to break up the soil, thereby improving the working efficiency of the paddy field wheel. However, the clay and mud in the paddy field provide significant resistance. Common blades are directly welded to the rotating shaft through round ribs. When the blades beat the mud, they come into contact with the mud as a whole, resulting in significant resistance. Furthermore, the contact area between the round ribs and the blades is small, making them prone to deformation when subjected to resistance. This causes the paddy field wheel to deform as a whole, thereby reducing its working efficiency and service life. Utility Model Content

[0005] In order to improve the working efficiency and service life of paddy field wheels, this utility model provides a paddy field wheel for a ride-on micro-tiller.

[0006] This application provides a paddy field wheel for a ride-on micro-tiller, which adopts the following technical solution:

[0007] A rideable micro-tiller with a paddy field wheel includes a rotating shaft and multiple tillage blades disposed on the rotating shaft. The multiple tillage blades are evenly distributed along the circumference of the rotating shaft. The rotating shaft is provided with a number of reinforcing plates for supporting the tillage blades. Each reinforcing plate corresponds to one tillage blade, and the outer end of the reinforcing plate is connected to the tillage blade.

[0008] By adopting the above technical solution, the power system of the riding micro-tiller drives the rotating shaft to rotate. The tilling blades rotate with the rotating shaft and till the soil in the paddy field. The reinforcing plate supports the tilling blades and bears part of the resistance of the tilling blades, thereby increasing the stability of the tilling blades and reducing the probability of the tilling blades deforming, thus improving the working efficiency and service life of the paddy field wheel.

[0009] Optionally, the rotating shaft is provided with a mounting assembly for mounting tillage blades.

[0010] Optionally, the installation components include:

[0011] The mounting shaft is provided in multiple ways, and the multiple mounting shafts are sequentially arranged on the rotating shaft circumferentially and extend radially along the rotating shaft.

[0012] The mounting ring is coaxially sleeved outside the rotating shaft, and the end of the mounting shaft away from the rotating shaft is connected to the inner surface of the mounting ring. Multiple tillage blades and reinforcing plates are disposed on the outer surface of the mounting ring.

[0013] By adopting the above technical solution, the mounting ring is connected to the rotating shaft, and the tillage blades and reinforcing plates are both set on the mounting ring. Compared with ordinary round rib installation, the mounting ring increases the contact area of ​​the tillage blades during installation, thereby improving the stability of the tillage blades and reducing the probability of deformation of the tillage blades and reinforcing plates, thus improving the working efficiency and service life of the paddy field wheel.

[0014] Optionally, the tillage blade includes an integrally formed mounting part and a working part. The mounting part has a trapezoidal structure that is wider on the outside and narrower on the inside, and the inner end of the mounting part is fixed to the mounting ring. The working part has a rectangular structure and is located at the outer end of the mounting part. The outer end of the reinforcing piece is connected to the working part.

[0015] By adopting the above technical solution, the mounting part is directly connected to the mounting ring, and the area of ​​the working part is larger than that of the mounting part, so as to improve the working efficiency of the tillage blade. Furthermore, when the tillage blade rotates as a whole, the mud can flow from the gap between the working part and the mounting part, thereby reducing the probability of mud adhering to the tillage blade, thus improving the working efficiency of the paddy field wheel.

[0016] Optionally, the working part has a connecting groove, and the outer end of the reinforcing piece extends into the connecting groove and is fixedly connected to the inner wall of the connecting groove.

[0017] By adopting the above technical solution, the outer end of the reinforcing sheet is fixed to the inner wall of the connecting groove, thereby increasing the connection strength between the reinforcing sheet and the tillage leaf, and thus increasing the stability of the tillage leaf and the reinforcing sheet.

[0018] Optionally, the working part has a protrusion, and the connecting groove is disposed in the protrusion.

[0019] By adopting the above technical solution and designing a protrusion, the depth of the connecting groove can be guaranteed without increasing the thickness of the working part, thus providing a reliable connection and increasing the stability of the tillage blade and the reinforcing blade.

[0020] Optionally, a reinforcing ring is coaxially provided on the outer side of the mounting ring, and the outer ends of the plurality of tillage blades are connected to the reinforcing ring.

[0021] By adopting the above technical solution, the reinforcing ring repositions the tillage blades, which not only increases the stability of the tillage blades, but also reduces the probability of the tillage blades directly contacting the ground and causing wear when the riding micro-tiller is moving on land. This improves the working efficiency and service life of the paddy field wheel.

[0022] Optionally, each of the outer edges of the plurality of tillage blades has a mounting groove, the reinforcing ring passes through the plurality of mounting grooves, the reinforcing ring has an adjustable opening, and the reinforcing ring is provided with an adjusting element for adjusting the size of the opening.

[0023] By adopting the above technical solution, the reinforcing ring is inserted into multiple mounting slots, and the opening size is adjusted by adjusting the adjustment component to adjust the fastening force of the reinforcing ring on the tillage blade, thereby improving the stability of the tillage blade.

[0024] Optionally, the adjusting component includes a connecting plate, a connecting bolt, and a connecting nut. There are two connecting plates, which are located at both ends of the reinforcing ring and are arranged opposite to each other. The connecting bolt passes through the two connecting plates, and the connecting nut is threaded onto the connecting bolt. When positioned, the connecting nut is pressed against the connecting plate.

[0025] By adopting the above technical solution, the connecting bolts are inserted through the two connecting plates, and the connecting nut is rotated to be pressed against the connecting plates for positioning, thereby realizing the adjustment of the tightening force of the reinforcing ring.

[0026] Optionally, the rotating shaft is a hexagonal tube, and the mounting shaft has six sections, each fixed to one of the six planes of the rotating shaft.

[0027] By adopting the above technical solution, the six mounting shafts are respectively fixed on the six planes of the rotating shaft, thereby achieving uniform force distribution and improving the stability of the paddy field wheel.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When the ride-on mini tiller starts, it drives the rotating shaft to rotate. The tilling blades rotate with the rotating shaft and till the soil in the paddy field. The reinforcing plate supports the tilling blades and bears part of the resistance of the tilling blades, so as to increase the stability of the tilling blades and reduce the probability of the tilling blades deforming, thereby improving the working efficiency and service life of the paddy field tiller.

[0030] 2. The mounting ring connects to the rotating shaft. The tillage blades and reinforcing plates are both mounted on the mounting ring. Compared with ordinary round rib mounting, the mounting ring increases the contact area of ​​the tillage blades during installation, thereby improving the stability of the tillage blades. This reduces the probability of deformation of the tillage blades and reinforcing plates, thus improving the working efficiency and service life of the paddy field wheel.

[0031] 3. By designing protrusions, the depth of the connecting groove is guaranteed without increasing the thickness of the working part, providing a reliable connection and thereby increasing the stability of the tillage blade and reinforcing plate. Attached Figure Description

The tilling blades 2 rotate with the mounting ring 42, turning over the soil in the paddy field. Compared with ordinary round rib installation, the mounting ring 42 increases the contact area of ​​the tilling blades 2 during installation. The reinforcing plate 3 supports the tilling blades 2 and bears part of the resistance encountered by the tilling blades 2, thereby increasing the stability of the tilling blades 2 during operation and reducing the probability of deformation. The reinforcing ring 5 further fixes the tilling blades 2, which not only increases the stability of the tilling blades 2, but also reduces the probability of wear caused by direct contact between the tilling blades 2 and the ground when the ride-on mini-tiller is moving on land. Therefore, it improves the working efficiency and service life of the paddy field wheels.
