Description

Technical Field

[0001] This utility model relates to the field of plowing equipment technology, and more specifically, to a rotary tillage plowing device. Background Technology

[0002] Rotary tillers primarily rely on their rotating cutter shaft and the blades mounted on it to operate. When the rotary tiller is powered by a power unit, the cutter shaft rotates, and the blades cut into the soil, breaking it up, turning it over, and spreading it out. This achieves the purposes of breaking up soil clods, loosening the soil, and mixing crop residues and fertilizers. During the tilling process, the rotary tiller continuously moves forward, and the cutter shaft rotates continuously, continuously processing the soil within a certain depth range.

[0003] Existing rotary tillers use blades fixedly mounted on a rotating shaft. The blades' unique shape allows for multi-faceted soil processing. Depending on the characteristics of the plant material, the required tillage depth varies. Furthermore, the depth needs to differ between initial tillage and subsequent tillage. Initial tillage requires a reduced depth to prevent blade overload, but existing equipment is inconvenient for adjusting blade extension distance, resulting in poor operability. Therefore, we propose a rotary tillage device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rotary tillage device to solve the technical problems of the current rotary tiller blades being fixedly installed, making it inconvenient to adjust the depth of penetration into the ground, and having poor operability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rotary tillage device, including a mounting frame, a shaft tube, and a blade. Both ends of the shaft tube are provided with assembly ends, and connectors are inserted into the assembly ends. The connectors are installed between adjacent partitions. The upper end of the partition is fixed to the lower side of the assembly plate, and adjacent assembly plates are spliced ​​together. A drive mechanism is fixed inside the mounting frame, and the mounting frame is connected to the assembly plates via a lifting rod. Connecting sleeves are distributed on the outer side of the shaft tube. A sliding rod is slidably installed inside the shaft tube. The connecting sleeves communicate with the interior of the shaft tube. A handle is fixed to the upper end of the blade, and the handle is inserted into the connecting sleeve. A bolt is installed through the connecting sleeve. A spring-loaded component is slidably installed in the groove of the handle.

[0006] In use, connectors are inserted and installed on the assembly ends of both ends of the shaft tube. The connectors are rotated and assembled before the partition plate. Adjacent shaft tubes are connected through the connectors. Rotating the adjusting gear meshes and drives the rotating drum. The rotating drum thread drives the side screw to move the sliding rod. The pressing groove of the sliding rod squeezes the pressing head and drives the cutter to move outward, causing the cutter to slide outward. Through the above structural design, the rotary tillage cutter of this device unfolds, increasing the working area and facilitating the selection of different rotary tillage modes according to the crop being planted, for in-depth soil processing. At the same time, the initial tillage and re-tillage can adopt corresponding rotary tillage depths to prevent damage to the cutter. When the pressing groove squeezes the pressing head and drives the cutter to slide outward, the lower concave opening of the arch bridge component engages with the bolt insertion part. During the outward sliding of the cutter, the lower pressing bolt of the arch bridge component slides in the groove of the cutter handle, and the second spring is compressed. When the pressure of the pressing head disappears, the rebound of the second spring drives the cutter to retract and reset. Through the above structural design, this device can automatically retract after unfolding and protruding, facilitating the switching of different working modes and reducing the difficulty of operation.

[0007] Preferably, an adjusting tooth is rotatably installed on the upper side of one end of the shaft tube, and a side insert rod and a side screw are fixed at both ends of the slide rod, respectively. A rotating cylinder is threaded onto the side screw and is rotatably installed inside the shaft tube. A pressure groove is opened on the outer side of the slide rod, and the pressure groove corresponds to the connecting sleeve.

[0008] Preferably, a first spring is sleeved on the side insert rod, a fixing ring is sleeved on the outer end of the side insert rod, and the fixing ring is fixed inside the shaft tube, and the outer end of the first spring is connected to the fixing ring.

[0009] Preferably, the upper end of the tool holder is fixed with a pressure head, and the pressure head passes through the connecting sleeve and connects to the pressure groove of the sliding rod. The tool has a streamlined design.

[0010] Preferably, the spring-loaded assembly consists of a second spring and an arch bridge, the arch bridge being slidably installed in the groove of the tool holder, and the lower recess of the arch bridge being aligned with the middle part of the bolt.

[0011] Preferably, a connecting rod is fixed to the upper side of both ends of the arch bridge component, and a second spring is fixed on the connecting rod, with the upper end of the second spring fixed to the top of the tool holder groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs a shaft tube with connectors inserted into the mounting ends at both ends. The connectors are rotatably mounted before the partition, and adjacent shaft tubes are connected through the connectors. Rotating the adjusting gears drives the rotating drum, and the rotating drum's threaded drive side screw drives the sliding rod to move. The pressure groove of the sliding rod squeezes the pressure head, causing the blade to move outward and slide outward. Through the above structural design, the rotary tillage blade of this device unfolds, increasing the working area and facilitating the selection of different rotary tillage modes according to the crop being planted for in-depth soil processing. At the same time, the initial tillage and re-tillage can use corresponding rotary tillage depths to prevent damage to the blades.

[0014] 2. This utility model also designs a cutting tool such that when the pressure head of the pressing groove drives the cutting tool to slide outward, the lower recess of the arch bridge component is engaged with the bolt insertion part. During the outward sliding of the cutting tool, the lower pressing bolt of the arch bridge component slides in the groove of the cutting tool handle, and the second spring is compressed. When the pressure of the pressing head disappears, the second spring rebounds and drives the cutting tool to retract and reset. Through the above structural design, the device can automatically retract after being extended, which facilitates the switching of different working modes and reduces the difficulty of operation.

The rotating adjusting gear 405 meshes and drives the rotating drum 806. The rotating drum 806 drives the side screw 804 to move the sliding rod 8. The pressing groove 803 of the sliding rod 8 presses the pressing head 701 and drives the cutter 7 to move outward, so that the cutter 7 slides outward. Through the above structural design, the rotary tillage cutter 7 of this device unfolds, increases the working area, and facilitates the selection of different rotary tillage modes according to the crop being planted for in-depth soil processing. At the same time, the initial tillage and re-tillage can adopt corresponding rotary tillage depths to prevent damage to the cutter 7.

[0025] like Figures 3 to 8As shown, this utility model relates to a rotary tillage device, including a mounting frame 3, a shaft tube 4, and a blade 7. A connecting sleeve 402 connects to the interior of the shaft tube 4. A handle 702 is fixed to the upper end of the blade 7, and the handle 702 is inserted into the connecting sleeve 402.
