Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tillage equipment, in particular to a rotary tillage blade replacement device. Background Art

[0002] A rotary tiller is a tillage machine used in conjunction with a tractor to complete tillage and harrowing operations. The rotary tillage blades are used for tilling the land. Through a unique installation method and by means of a rotating operation, the rotary tillage blades break up the soil on the cultivated land to meet the tillage needs. When the rotary tillage blades contact the ground, long-term contact will cause damage to the blades. In severe cases, the blades will be unable to break up the soil. Therefore, the blades need to be replaced after a certain period of use. Currently, the blades are only clamped through bolts and connecting components. When the blades rotate to break up the soil, once the blades collide with hard stones, the connecting parts of the blades are extremely vulnerable to the impact and become loose. Moreover, a large number of bolts are used during connection, resulting in relatively cumbersome replacement in the later stage.

[0003] To solve the above problems, the prior art patent (CN219205156U) discloses a rotary tillage blade replacement device for a rotary tiller, which includes a rotary tiller body, a rotating shaft, a connecting component connected to the rotating shaft, and rotary tillage blades used for tilling the land by the rotary tiller. The connecting component includes at least two positioning rings and a connecting ring located between the two positioning rings. A tool mounting hole for inserting the rotary tillage blade is provided on the outer side of the ring body of the connecting ring; the two positioning rings are adapted to the rotary tillage blade through clamping protrusions for fixing the rotary tillage blade; the utility model realizes the installation and fixation of the rotary tillage blade through the connecting component composed of two positioning rings and a connecting ring, in cooperation with the installation of the rotary tillage blade in the tool mounting hole on the connecting component. In cooperation with the tool limiting grooves on both sides inside the tool mounting hole, when the rotary tillage blade contacts and collides with the ground stones, the displacement generated during the collision can be restricted by the tool limiting grooves.

[0004] However, in the above prior art, the installation position of the rotary tillage blade is fixed, and the installation position of the rotary tillage blade on the rotating shaft cannot be adjusted according to the requirements of different cultivated lands, reducing the convenience and practicality of the device.

Figure 2 It is a front view of the first embodiment of the present utility model. Figure 3 It is a schematic diagram of a partial structure of the first embodiment of the present utility model.

[0022] The present utility model provides a rotary tillage blade replacement device, which includes a rotary tillage blade cover 101, a drive motor 102, a drive shaft 103, a disassembly cover 104, a fixing bolt 105, and multiple groups of adjusting components. Each group of the adjusting components includes two sets of mounting parts and dismounting parts. Each set of the mounting parts includes a locking sleeve 106, an adjusting bolt 107, a sliding block 108, two friction pads 109, and three locking bolts 110. The dismounting part includes a connecting ring 111 and three cutting blades 112. The foregoing solution solves the problem that the installation position of the rotary tillage blade is fixed, and it is impossible to adjust the installation position of the rotary tillage blade on the rotating shaft according to the requirements of different cultivated lands, reducing the convenience and practicality of the device use.

[0023] For this specific embodiment, the drive motor 102 is fixedly connected to one end of the drive shaft 103 and is located outside the rotary tillage blade cover 101. The other end of the drive shaft 103 is rotatably connected to the disassembly cover 104 and is located inside the rotary tillage blade cover 101. The disassembly cover 104 is detachably connected to the rotary tillage blade cover 101 and is located outside the rotary tillage blade cover 101. The fixing bolt 105 is threadedly connected to the rotary tillage blade cover 101 and is located outside the rotary tillage blade cover 101, and the fixing bolt 105 penetrates through the disassembly cover 104. Multiple groups of the adjusting components are arranged outside the drive shaft 103. Each group of the adjusting components includes two sets of mounting parts and dismounting parts. The two sets of the mounting parts are symmetrically arranged. The mounting parts are slidably connected to the drive shaft 103 and are located outside the drive shaft 103. The dismounting part is threadedly connected to the mounting parts and is located between the two sets of the mounting parts. Remove the fixing bolt 105, take off the disassembly cover 104, slidably mount the mounting parts to a set position outside the drive shaft 103, then press the dismounting part against the mounting parts, and fix the dismounting part through the two sets of the mounting parts. In this way, multiple groups of the adjusting components are installed reciprocally. After the installation is completed and reinstalled, the drive shaft 103 is driven to rotate by the drive motor 102. By this method, the problem that the installation position of the rotary tillage blade on the rotating shaft cannot be adjusted according to the requirements of different cultivated lands can be effectively solved.

[0024] Among them, the locking sleeve 106 is slidably connected to the drive shaft 103 and is located outside the drive shaft 103. The adjusting bolt 107 is rotatably connected to the sliding block 108 and is located outside the locking sleeve 106, and the adjusting bolt 107 penetrates through the locking sleeve 106. The sliding block 108 is slidably connected to the drive shaft 103 and is located inside the drive shaft 103. The sliding block 108 and the locking sleeve 106 are slidably installed outside the drive shaft 103. After the locking sleeve 106 moves to the set position, rotate the adjusting bolt 107 to push the sliding block 108 to abut against the drive shaft 103, thereby fixing the locking sleeve 106, facilitating the adjustment of the installation position according to different tillage requirements and improving the flexibility of the device.

[0025] Secondly, the two friction pads 109 are fixedly connected to the locking sleeve 106 and are located outside the locking sleeve 106. The three locking bolts 110 are threadedly connected to the locking sleeve 106 and penetrate through the locking sleeve 106. The two friction pads 109 facilitate manually dragging the locking sleeve 106 to improve the adjustment efficiency of the locking sleeve 106.

[0026] At the same time, the connecting ring 111 is slidably connected to the drive shaft 103 and is located outside the locking sleeve 106. The three cutting tools 112 are detachably connected to the connecting ring 111 and are located outside the connecting ring 111, and the locking bolt 110 penetrates through the cutting tool 112. The connecting ring 111 fits against the locking sleeve 106. Insert the cutting tool 112 into the connecting ring 111 and fix the cutting tool 112 and the connecting ring 111 through the locking bolt 110, thereby facilitating the individual replacement of the cutting tool 112 and improving the replacement efficiency of the rotary tillage knife.

[0027] In addition, the drive shaft 103 has an adjustment groove 113 adapted to the sliding block 108, and the connecting ring 111 has a card slot 114 adapted to the cutting tool 112.
