[0024] Example

[0025] Reference Figure 1-4This is an embodiment of the present invention, which provides a tracked rotary tillage and slurry-making machine for paddy fields, comprising:

[0026] The drive mechanism 100 includes an operating compartment 101, a drive wheel 102 adapted to be installed at the bottom of the operating compartment 101, and a drive track 103 used in conjunction with the drive wheel 102.

[0027] The operating mechanism 200 includes a first cylinder 201 adapted to be installed on the side surface of the operating chamber 101, a fixed rod 202 fixedly installed on the output end of the first cylinder 201, a scraper 203 fixedly connected to the bottom of the fixed rod 202, a second cylinder 204 adapted to be installed on the side surface of the fixed rod 202, a rotary tillage assembly 205 fixedly installed on the output end of the second cylinder 204, a mounting plate 206 snapped onto the side wall of the fixed rod 202, a third cylinder 207 adapted to be installed on the side surface of the mounting plate 206, an auxiliary rod 208 fixedly installed on the output end of the third cylinder 207, a pull rod 209 fixedly connected to the side end of the auxiliary rod 208, and a pulverizing rod 210 used in conjunction with the pull rod 209.

[0028] Specifically, firstly, the drive motor 102a, controlled by the operating chamber 101, rotates the transmission rod 102b, driving the transmission wheel 102c to engage with the teeth on the inner surface of the track, enabling the machine to move stably in the paddy field; the first cylinder 201 pushes the fixed rod 202 down, causing the scraper 203 to contact the ground and pre-scrape the surface soil; the second cylinder 204 then pushes the rotary tillage assembly 205 down, and the connecting rod 205b drives the rotating rod 205c to rotate, causing the rotary tillage blades 205d to penetrate deep into the soil for rotary tillage; simultaneously, the third cylinder 207 pushes the auxiliary rod 20... The 8th action involves adjusting the position of the auxiliary wheel 208d to maintain balance via the limit rod 208b and the fixing frame 208c. When the auxiliary wheel 208d rotates, it drives the pull rod 209 to move. The pull rod 209 drives the slurrying rod 210 to swing back and forth through the elastic locking mechanism. The slot 210b of the slurrying rod 210 and the locking block 209e of the pull rod 209 are tightly engaged, so that the contact rod 210a slurries the rotary tilled soil to form a uniform slurry. The coordinated adjustment of each cylinder can achieve precise control of the rotary tillage depth and slurry intensity, completing the integrated operation of paddy field tillage and preparation.

[0029] The drive wheel 102 includes a drive motor 102a adapted to be installed at the bottom of the operating compartment 101, a transmission rod 102b fixedly installed at the output end of the drive motor 102a, and a transmission wheel 102c rotatably installed at the side end of the transmission rod 102b.

[0030] The drive wheel 102c contacts the inner surface of the drive track 103 and operates in cooperation. The inner surface of the drive track 103 is provided with locking teeth. The drive wheel 102c is provided with a pair and multiple sets. The locking teeth are used in cooperation with the drive wheel 102c.

[0031] The rotary tillage assembly 205 includes a fixed plate 205a fixedly installed at the end of the second cylinder 204, a connecting rod 205b inserted into the side surface of the fixed plate 205a, a rotating rod 205c rotatably installed on the side surface of the connecting rod 205b, and a rotary tillage blade 205d fixedly installed on the side surface of the rotating rod 205c.

[0032] Furthermore, the drive motor 102a drives multiple pairs of transmission wheels 102c to rotate via the transmission rod 102b. The transmission wheels 102c mesh with the teeth on the inner surface of the drive track 103, propelling the entire machine to move stably in the paddy field. The second cylinder 204 pushes the fixed plate 205a down, which drives the rotating rod 205c and rotary tiller blades 205d to penetrate deeper into the soil layer via the connecting rod 205b. During movement, the rotary tiller blades 205d rotate and break up the soil. At the same time, the first cylinder 201 controls the scraper 203 to pre-scrape the surface layer, and the third cylinder 207 drives the slurrying rod 210 to slurry the soil after rotary tillage via the auxiliary rod 208. The meshing design of multiple sets of transmission wheels 102c and the track ensures stable power transmission. The rotary tiller blades 205d adapt to different tillage depths through an adjustable connection structure, realizing efficient operation of integrated rotary tillage and slurrying.

[0033] The auxiliary rod 208 includes a rotating plate 208a fixedly installed at the end of the third cylinder 207, a limiting rod 208b inserted into the side wall of the rotating plate 208a, a fixed frame 208c fixedly installed at the end of the limiting rod 208b, and an auxiliary wheel 208d rotatably installed on the side surface of the fixed frame 208c.

[0034] The pull rod 209 includes a rod body 209a, a mounting groove 209b formed on the side surface of the rod body 209a, a support rod 209c fixedly connected to the center of the mounting groove 209b, a push plate 209d sleeved on the side wall of the support rod 209c, a locking block 209e fixedly connected to one side of the push plate 209d, elastic blocks 209f fixedly connected to both sides of the locking block 209e, a disassembly rod 209g used in conjunction with the locking block 209e, and a spring 209h fixedly connected to the other side of the push plate 209d.

[0035] The pulverizing rod 210 includes a contact rod 210a, a slot 210b formed on the side surface of the contact rod 210a, and a locking groove 210c communicating with the slot 210b. The slot 210b engages with the locking block 209e, and the locking groove 210c engages with the elastic block 209f.

[0036] Preferably, the third cylinder 207 pushes the rotating plate 208a to move the limiting rod 208b and the fixing frame 208c, so that the auxiliary wheel 208d maintains stable rotation during operation. The auxiliary wheel 208d drives the slurrying rod 210 through the pull rod 209. The locking block 209e of the pull rod 209 is tightly engaged with the locking groove 210b of the slurrying rod 210 under the action of the spring 209h. At the same time, the elastic block 209f is embedded in the locking groove 210c to achieve double fixation. When the slurrying rod 210 contacts the mud, the push plate 209d slides along the support rod 209c and compresses the spring 209h to form a buffer effect. The disassembly rod 209g can quickly release the connection between the locking block 209e and the locking groove 210b. The entire slurrying mechanism reciprocates under the drive of the auxiliary wheel 208d, so that the contact rod 210a can uniformly slurry the mud after rotary tillage. The elastic connection structure can ensure stable force transmission and effectively absorb the impact of operation.

[0037] In operation, the operator first starts the system through the control chamber 101, driving the motor 102a to rotate the transmission rod 102b, causing the multiple pairs of transmission wheels 102c to mesh with the teeth on the inner surface of the track, providing stable tracked walking power for the whole machine and ensuring passability and stability in muddy paddy fields. During operation, the first cylinder 201 pushes the fixed rod 202 and scraper 203 down to pre-scrape the surface soil; the second cylinder 204 simultaneously pushes the rotary tillage assembly 205 down, driving the rotating rod 205c to rotate through the fixed plate 205a and connecting rod 205b, causing the rotary tillage blades 205d to cut into the soil layer at an adjustable depth for crushing operations. At the same time, the third cylinder 207 rotates the rotating plate 208. a. The limiting rod 208b and the fixing frame 208c adjust the position of the auxiliary wheel 208d. The auxiliary wheel 208d drives the pull rod 209 mechanism to move. The pull rod 209 drives the pulverizing rod 210 to reciprocate through its unique elastic connection mechanism. The pulverizing rod 210 ensures a firm connection and has a buffer function through the precise cooperation between the slot 210b and the locking block 209e, and the double locking of the elastic block 209f and the locking groove 210c. This allows the contact rod 210a to perform uniform and efficient pulverizing treatment on the rotary tilled soil. Through the coordinated control of multiple cylinders, the rotary tillage depth and pulverizing intensity can be precisely adjusted. Each transmission component adopts a modular design for easy maintenance, ultimately completing the integrated and efficient operation of paddy field tillage.

[0038] In summary, the drive system, employing multiple sets of transmission wheels 102c and toothed tracks, significantly improves traction and maneuverability in muddy paddy fields, effectively solving the problem of traditional wheeled machinery easily slipping and getting stuck. The working mechanism, controlled by three sets of cylinders, enables precise adjustment of rotary tillage depth and slurry intensity, adapting to different soil types and agronomic requirements. The unique elastic snap-fit ​​slurry mechanism, with spring 209h buffering and double locking design, ensures operational stability while effectively absorbing impact loads and extending equipment lifespan. The modular rotary tillage components 205 and quick-disassembly structure greatly simplify maintenance procedures. The machine integrates leveling, rotary tillage, and slurry functions, significantly improving operational efficiency and reducing energy consumption through optimized workflow. The combined use of the tracked chassis and adjustable working parts ensures both operational quality and adaptability to various complex paddy field environments.
