Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a paddy field harrowing and leveling machine. Background Technology

[0002] The paddy field harrowing and leveling machine is a type of agricultural machinery specifically designed for paddy fields. It is mainly used for tilling, leveling, and harrowing paddy fields. The paddy field harrowing and leveling machine can quickly complete the leveling of large areas of paddy fields, improving work efficiency.

[0003] In existing technology, paddy field harrowing and leveling machines cannot quickly adjust the distance between rotary tillage blades. A fixed blade spacing may lead to excessive soil compaction, affecting soil aeration and moisture retention, which in turn affects root development. If the blade spacing is not adapted to soil conditions, it may lead to accelerated blade wear, increasing maintenance and replacement costs. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a paddy field harrowing and leveling machine.

[0005] This utility model is achieved by the following technical solution: a paddy field harrowing and leveling machine, including an adjustment mechanism, a transmission mechanism and an anti-splash mechanism, wherein the adjustment mechanism is located at the bottom of the transmission mechanism and the anti-splash mechanism is located at the back of the transmission mechanism;

[0006] The adjustment mechanism includes a fixed rod, a slot on the outer wall of the fixed rod, a sliding groove on the outer wall of the fixed rod, a slider in contact with the outer wall of the slot, a bolt threaded inside the slider, the bolt threaded inside the fixed rod, a connecting ring fixedly connected to the outer wall of the slider, and a rotary tiller blade fixedly connected to the outer wall of the connecting ring.

[0007] With the above technical solution, when the fixed rod rotates, it drives the connecting ring to rotate via the slider. The connecting ring then drives the rotary tiller blades to rotate, thereby performing rotary tillage on the paddy field. To address different soil types, the bolts are loosened using a tool. Once the bolts are removed, the slider is released and slides out of the slot into the groove, causing the connecting ring to move and adjusting the distance between the blades. Different paddy field types and crop growth stages have different requirements for tillage depth and blade spacing, which can be adjusted according to specific conditions to improve operational efficiency. Furthermore, the rotary tiller blades can be quickly replaced, increasing operational efficiency.

[0008] As a further improvement to the above solution, several connecting rings are provided, and the several connecting rings are evenly arranged on the outer wall of the fixing rod; several rotary tillers are provided, and the several rotary tillers are evenly arranged on the outer wall of the fixing rod.

[0009] As a further improvement to the above solution, the transmission mechanism includes a power output rod, the outer end of which is fixedly connected to a universal joint, the outer wall of which is fixedly connected to a fixed column, and the outer wall of which is rotatably connected to a bracket.

[0010] As a further improvement to the above solution, a baffle is fixedly connected to the bottom of the bracket, the fixed column is rotatably connected inside the baffle, an inner groove is opened inside the bracket, a slider is rotatably connected to the outer wall of the inner groove, and a gear is fixedly connected to the end of the fixed column away from the universal joint.

[0011] As a further improvement to the above solution, the gear meshes with a gear one, the gear one is fixedly connected to the outer wall of the fixed rod, the outer wall of the fixed rod is rotatably connected to a fixed block, the fixed block is fixedly connected to the bottom of the baffle, and there are two fixed blocks, which are symmetrically arranged about the center of the fixed rod.

[0012] With the above technical solution, the power output rod drives the fixed column to rotate through a universal joint. The fixed column rotates inside the bracket and the baffle respectively. An inner groove is opened inside the bracket, and the inner groove is rotatably connected to the slider. At the same time, the slider is fixed to the outer wall of the fixed column, thus ensuring that the fixed column always rotates in the same position. This allows the gear fixed at the bottom of the fixed column to mesh more effectively with the gear. The gear drives the fixed rod to rotate. Meanwhile, the fixed block is fixed to the bottom of the baffle, and the fixed rod rotates inside the fixed block, thus making the rotation of the fixed rod more stable and providing a stable output.

[0013] As a further improvement to the above solution, the anti-splash mechanism includes a first fixing block, which is fixedly connected to the back of the bracket. A connecting rod is fixedly connected to the outer wall of the first fixing block. A second fixing block is rotatably connected inside the connecting rod. A sliding rod is slidably connected inside the second fixing block. A spring is provided in contact with the outer wall of the sliding rod. A limit plate is fixedly connected to the end of the sliding rod near the second fixing block, and a connecting column is fixedly connected to the end of the sliding rod away from the limit plate.

[0014] As a further improvement to the above solution, a connecting rod one is rotatably connected inside the connecting column, a support plate is fixedly connected to the outer end of the connecting rod one, a mudguard is fixedly connected to the bottom of the support plate, and a connecting rod two is rotatably connected to the end of the mudguard away from the support plate, and the connecting rod two is fixedly connected to the outer wall of the mudguard.

[0015] With the above technical solution, when the rotary tiller blades rotate, mud and water will splash. The mudguard is rotatably connected to the baffle via connecting rod two, thus preventing splashing. To adapt to different terrains, the sliding rod slides inside the fixed block two. The fixed block two is rotatably connected to the connecting rod, effectively preventing the sliding rod from jamming. A spring is installed on the outer wall of the sliding rod. The reaction force of the spring causes connecting rod one to drive the support plate to press the mudguard down, preventing the mudguard from fluctuating up and down during operation, reducing mud interference, improving the working efficiency of the rotary tiller, and also reducing mud splashing into the machine, which helps to reduce equipment wear and failure risk and extend service life.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a fixed rod that rotates, causing a connecting ring to rotate via a slider. The connecting ring then rotates the rotary tiller blades, thus performing rotary tillage on the paddy field. To address different soil types, a bolt is loosened using a tool. Once the bolt is removed, the slider is released, disengaging from its slot and sliding into a groove. This allows the connecting ring to move, adjusting the distance between the blades. Different paddy field types and crop growth stages require different tillage depths and blade spacing, allowing for adjustments based on specific conditions to improve operational efficiency. Furthermore, the rotary tiller blades can be quickly replaced, enhancing operational efficiency.

[0018] This invention utilizes the principle that when the rotary tiller blades rotate, mud and water splash. A mudguard is rotatably connected to the baffle via a connecting rod, preventing splashing. To adapt to different terrains, a sliding rod slides inside a fixed block. The fixed block, rotatably connected to the connecting rod, effectively prevents the sliding rod from jamming. A spring is installed on the outer wall of the sliding rod; the spring's reaction force causes the connecting rod to drive the support plate, pressing the mudguard downwards and preventing it from fluctuating during operation. This reduces mud interference, improves the rotary tiller's operating efficiency, and also reduces mud splashing into the machine, helping to reduce wear and tear, the risk of malfunction, and extend the machine's service life.

[0034] A baffle 205 is fixedly connected to the bottom of the bracket 204, and a fixed column 203 is rotatably connected inside the baffle 205. An inner groove 206 is opened inside the bracket 204, and a slider 207 is rotatably connected to the outer wall of the inner groove 206. A gear 208 is fixedly connected to the end of the fixed column 203 away from the universal joint 202.

[0035] Gear 208 is meshed with gear 209, gear 209 is fixedly connected to the outer wall of fixed rod 101, and fixed block 210 is rotatably connected to the outer wall of fixed rod 101. Fixed block 210 is fixedly connected to the bottom of baffle 205. There are two fixed blocks 210, and the two fixed blocks 210 are symmetrically arranged with respect to the center of fixed rod 101.

[0036] The splash-proof mechanism 3 includes a first fixing block 301, which is fixedly connected to the back of the bracket 204.

[0038] The implementation principle of the paddy field harrowing and leveling machine in this embodiment is as follows: the power output rod 201 drives the fixed column 203 to rotate through the universal joint 202. The fixed column 203 rotates inside the bracket 204 and the baffle 205 respectively. An inner groove 206 is opened inside the bracket 204, and the inner groove 206 is rotatably connected to the slider 207. At the same time, the slider 207 is fixed to the outer wall of the fixed column 203, thereby ensuring that the fixed column 203 always rotates in the same position, so that the gear 208 fixed at the bottom of the fixed column 203 meshes more effectively with the gear 209. 09 drives the fixed rod 101 to rotate, while the fixed block 210 is fixed to the bottom of the baffle 205.

When the bolt 105 is removed, the slider 104 is released. Release, slider 104 disengages from slot 102 and slides into groove 103, thereby moving connecting ring 106 and adjusting the distance between blades. Different paddy field types and crop growth stages have different requirements for tillage depth and blade spacing, which can be adjusted according to specific conditions to improve work efficiency. It also allows for quick replacement of rotary tillage blades 107, improving work efficiency. When rotary tillage blades 107 rotate, they cause mud and water to splash. Mudguard 310 is rotatably connected to baffle 205 via connecting rod 311 to prevent splashing. To adapt to different terrains... In this configuration, the slide rod 304 slides inside the fixed block 303. The fixed block 303 is rotatably connected to the connecting rod 302, effectively preventing the slide rod 304 from jamming. A spring 305 is installed on the outer wall of the slide rod 304. The reaction force of the spring 305 causes the connecting rod 308 to drive the support plate 309 to press the mudguard 310 down, preventing the mudguard 310 from fluctuating up and down during operation, reducing soil interference, improving the working efficiency of the rotary tiller, and also reducing soil splashing into the machine, which helps to reduce equipment wear and failure risk and extend service life.
