Description

Technical Field

[0001] The utility model belongs to the technical field of rotary tillers, and in particular relates to a rotary tiller with higher safety performance. Background Art

[0002] A rotary tiller is a driven soil cultivation machine with rotating blades as working parts. It is mainly used for shallow tillage. It can finely process the soil and improve the soil's air permeability and water retention. Rotary tillers usually install baffles on the rotary blades for protection to prevent injuries to personnel caused by soil splashing.

[0003] For example, a Chinese patent with publication number CN219698394U discloses a rotary tiller with relatively high safety performance, including a rotary tiller body, both sides of which are movably connected to a rotary tiller blade body, and a mounting block is fixedly connected to the front end of the top of the rotary tiller body.

[0004] Although the above-mentioned rotary tiller has solved the problems of soil splashing and the risk of operators being accidentally entangled, there are still some shortcomings that need to be improved. During high-intensity operations, it is still difficult to completely avoid some soil particles from being splashed out through the gap behind the metal rake. This phenomenon may not only pollute the surrounding environment, but also pose a potential threat to the safety of surrounding workers. In addition, the metal rake, as the core working component of the rotary tiller, will experience severe wear after working for a long time. The existing metal rake is not easy to disassemble and replace quickly, which is not conducive to the maintenance of the rotary tiller. Utility Model Content

Detailed implementation manners

[0022] Embodiment

[0023] Refer to Figures 1 to 6, A rotary tiller with relatively high safety performance described in this embodiment includes a rotary tiller body 1. One end of the rotary tiller body 1 is fixedly connected to a tool holder 2. A rotary tiller blade 3 is rotatably connected inside the tool holder 2. One end of the tool holder 2 away from the rotary tiller body 1 is fixedly connected to a mounting frame 4. A dovetail slider 6 is slidably connected inside the mounting frame 4. A baffle 5 is fixedly connected to the bottom end of the dovetail slider 6. The setting of the dovetail slider 6 makes the baffle 5 unable to fall off the mounting frame 4 and can only move horizontally. It should be noted that a baffle 5 can also be installed in front of the tool holder 2 to block soil. Due to the existence of the rotary tiller body 1, the protection requirement in the front is not as great as that in the rear, so it will not be elaborated here. A first fixing component 7 is fixedly connected to the top end of the mounting frame 4. The dovetail slider 6 is fixedly connected to the mounting frame 4 through the first fixing component 7. One end of the baffle 5 is provided with a mounting plate 11. A second fixing component 13 is provided on one side of the mounting plate 11. A metal rake 12 is fixedly connected to the bottom end of the mounting plate 11 through the second fixing component 13. Through the above settings, when the rotary tiller body 1 is working, it can effectively block the soil from splashing from behind the metal rake 12, reduce the pollution of the surrounding environment caused by soil splashing, and also facilitate the disassembly and maintenance of the metal rake 12, improving the maintenance efficiency and convenience.

[0024] Reference Figure 3 , The first fixing component 7 includes a fixing block 71. The fixing block 71 is fixedly connected to the top end of the mounting frame 4. A slide plate 74 is slidably connected inside the fixing block 71. Both sides of one end of the slide plate 74 are fixedly connected with positioning blocks 75. Positioning grooves 76 are opened on both sides of the top end of the dovetail slider 6. The positioning blocks 75 are movably connected with the positioning grooves 76. A first lead screw 73 is rotatably connected inside the fixing block 71. The top end of the first lead screw 73 is fixedly connected with a first torsion block 72. The slide plate 74 is threadedly connected to the first lead screw 73. By setting the first fixing component 7, when the positioning block 75 is inserted into the positioning groove 76, the dovetail slider 6 is fixedly connected to the fixed frame, making the baffle 5 firmly installed without falling off. When it is necessary to remove the baffle 5 for maintaining the baffle 5 or the metal rake 12, rotate the first torsion block 72. The first torsion block 72 drives the lead screw to rotate inside the fixing block 71, causing the slide plate 74 on the surface of the lead screw to move. The slide plate 74 drives the positioning block 75 to move, so that the positioning block 75 can leave the positioning groove 76, and the dovetail slider 6 is no longer fixedly connected to the fixed frame, and the baffle 5 can be removed, facilitating the cleaning of the baffle 5 and the replacement of the metal rake 12.

[0025] Reference Figure 5, one end of the baffle 5 is fixedly connected to a fixing plate 8. The bottom end of the fixing plate 8 is fixedly connected to a shock-absorbing spring 9 and a damper 10. The shock-absorbing spring 9 is located outside the damper 10. The bottom ends of the shock-absorbing spring 9 and the damper 10 are fixedly connected to the top end of the mounting plate 11. By installing the fixing plate 8 at one end of the baffle 5, and connecting the fixing plate 8 to the mounting plate 11 through the shock-absorbing spring 9 and the damper 10, it plays a certain role in shock absorption and buffering during the working process of the metal rake 12, avoiding the reduction of the service life caused by hard contact of the metal rake 12, and greatly improving the service life of the metal rake 12.

[0026] Reference Figure 5 , the second fixing component 13 includes a guide groove 131. The guide groove 131 is opened on both sides of the upper end of the metal rake 12. A jack 132 is opened inside the guide groove 131. A guide block 133 is slidably connected inside the guide groove 131. A plug rod 134 is inserted inside the jack 132. One end of the plug rod 134 is fixedly connected to one end of the guide block 133. A chute 135 is opened at the lower end of the mounting plate 11. A second lead screw 136 is rotatably connected inside the chute 135. One end of the second lead screw 136 is fixedly connected to a second torsion block 137. By setting the second fixing component 13, when it is necessary to remove the metal rake 12, rotate the second torsion block 137. The second torsion block 137 drives the lead screw to rotate inside the chute 135, so that the guide block 133 on the surface of the lead screw moves inside the guide groove 131, and the plug rod 134 leaves the jack 132, and then the metal rake 12 can be removed and replaced. The operation is very simple and convenient. It should be noted that the threads of the two lead screws are set in opposite directions, and the ends of the two lead screws are connected by a shaft rod.

[0027] Reference Figure 1 , one end of the tool holder 2 is fixedly connected to a motor 14. The output end of the motor 14 is fixedly connected to a first pulley 15. One end of the rotary tillage blade 3 is fixedly connected to a second pulley 16. The first pulley 15 is drivingly connected to the second pulley 16 through a transmission belt 17. The motor 14 drives the first pulley 15 to rotate. The first pulley 15 drives the second pulley 16 to rotate through the transmission belt 17, and the second pulley 16 drives the rotary tillage blade 3 to rotate to process the soil.

[0028] Principle of use and advantages: When the rotary tiller body 1 moves, it drives the tool holder 2 to move, so that the rotary tiller blades 3 below the tool holder 2 move. The motor 14 drives the first pulley 15 to rotate. The first pulley 15 drives the second pulley 16 to rotate through the transmission belt 17. The second pulley 16 drives the rotary tiller blades 3 to rotate to process the soil. At the same time, the metal harrow 12 tills the land. The shock-absorbing springs 9 and dampers 10 between the mounting plate 11 and the fixing plate 8 can shock-absorb and buffer the metal harrow 12 to protect the metal harrow 12. The soil splashed backward by the rotary tiller blades 3 is first blocked by the metal harrow 12 and then blocked by the rear baffle 5, reducing the pollution of the surrounding environment caused by soil splashing, significantly improving the safety of the operation site, and ensuring the personal safety of the operator. When it is necessary to replace the metal harrow 12, rotate the first knob 72. The first knob 72 drives the lead screw to rotate in the fixed block 71, so that the slide plate 74 on the surface of the lead screw moves. The slide plate 74 drives the positioning block 75 to move, so that the positioning block 75 can leave the positioning groove 76, and the dovetail slider 6 is no longer fixed to the fixed frame. First, remove the baffle 5, and then rotate the second knob 137. The second knob 137 drives the lead screw to rotate in the chute 135, so that the guide block 133 on the surface of the lead screw moves in the guide groove 131, and the insertion rod 134 leaves the insertion hole 132. The operator can easily remove the metal harrow 12 from the mounting plate 11 for replacement or maintenance. The whole process does not require the assistance of complex tools, greatly improving the maintenance efficiency and convenience.
