Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a rotary tillage device for agricultural machinery. 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 flat surface they leave after tilling; at the same time, they can chop up the stubble buried below the surface, making it easier for seeders to operate and providing a good seedbed for later sowing.

[0003] In the prior art, such as Chinese Patent (Patent Publication No. CN215073766U), a rotary tiller for agricultural machinery is disclosed. It includes a rotary tiller plate, a lifting mechanism, and a cleaning mechanism. The lifting mechanism is installed on the outer wall of the rotary tiller plate. The lifting mechanism includes a lifting plate, a guide groove, a guide block, an internal threaded block, a threaded rod, a limiting block, a transmission shaft, and a drive motor. The outer surface of the lifting plate has a guide groove, and a guide block slides inside the guide groove. The rotary tiller plate is fixedly connected to the left side of the guide block. This rotary tiller for agricultural machinery uses a drive motor to rotate the transmission shaft, which in turn rotates the threaded rod. The threaded rod engages with the internal threaded block, converting the rotational motion of the threaded rod into the lifting motion of the internal threaded block. The internal threaded block drives the guide block to move up and down, and the guide block slides directionally along the guide groove on the lifting plate. The height of this rotary tiller for agricultural machinery is adjustable to meet different working needs.

[0004] Although the above-mentioned rotary tiller for agricultural machinery has the advantages of being highly adjustable and easy to clean the soil on the tiller, when operating in fields with clay soil or a lot of weeds, the tiller blades are easily stuck and tangled by clay or weeds, which affects the rotation of the blades and the tillage effect, increases the amount of cleaning work and the number of times the operation is interrupted. Therefore, we propose a new type of rotary tiller for agricultural machinery. Utility Model Content

Debris and other debris entering the connection area can affect the disassembly of the tiller body 204. Then, a fixing plate 207 is snapped between a set of fixing rollers 202. A set of connecting bolts 208 are inserted through the fixing plate 207, and these bolts 208 are inserted through the end cap 206 and the fixing rollers 202 to securely fix the set of fixing rollers 202 into a single unit, ensuring the synchronous rotation of the tiller body 204. Finally, threaded grooves 209 are formed on the outer wall of each set of connecting bolts 208, and fastening nuts 210 are threaded onto the outer wall of each connecting bolt 208 to secure it. Then, the motor 211 is fixedly installed on one side of the first bracket 101. The output end of the motor 211 is fixedly connected to one end of the rotating shaft 201. The motor 211 drives the tillage blade body 204 to rotate for tillage. A set of scrapers 103 are respectively set between the set of tillage blade bodies 204, and a set of brushes 104 are respectively set on the outer wall of the set of tillage blade bodies 204.
