Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an angle adjustment device for a ridge builder. Background Art

[0002] The harrow-type soil covering and ridge building device is an agricultural machinery component, which is mainly used for soil covering and ridge building operations in farmland. It can build ridges in farmland, which helps to divide different planting areas, facilitate irrigation and drainage, prevent soil erosion, and improve the soil and water conservation capacity of farmland. In some areas where terrace construction or paddy field transformation is required, the harrow-type soil covering and ridge building device can also play an important role. By building ridges, the terrain can be changed, and the land utilization rate and agricultural production efficiency can be improved.

[0003] The size of the rake blade rotation angle determines the size of the soil test volume.

After the adjustment is completed, it is only necessary to put down the gear sleeve 207 to make the gear sleeve 207 and the outer teeth 206 re-engage, and continue to limit the main sleeve 1. By setting the adjustment mechanism 2, a gear sleeve 207 that can slide up and down is installed on the main square tube 201, and an outer tooth 206 is added to the rotating end of the main sleeve 1. When the angle needs to be adjusted, the gear sleeve 207 is lifted up and disengaged from the outer tooth 206. After turning to the appropriate angle, the engaged gear sleeve 207 is put down to engage with the teeth. At this time, the two ends of the main sleeve 1 can no longer rotate freely, the angle is locked, and you can work with confidence. The gear sleeve 207 will not disengage from the teeth under the action of gravity, and the work is very stable.

[0033] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the bottom of the main sleeve 1 overlaps the top of the bottom nut 203 to prevent the main sleeve 1 from slipping.

[0034] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a square hole 2071 that is adapted to the shape of the main square tube 201 is opened on the body of the gear sleeve 207, and a special-shaped groove that is adapted to the shape of the external teeth 206 is opened on the bottom of the gear sleeve 207 to facilitate tight engagement.

[0035] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the outer side of the main square tube 201 is movably connected to the main sleeve 1 through a bearing, the main sleeve 1 is connected to the outer ring of the bearing, and the outer ring of the main square tube 201 is connected to the inner ring of the bearing through a structural part.

[0036] Reference Figures 1-4Based on the same concept as the first embodiment, this embodiment further provides a fastening mechanism 3 provided on the body of the main square tube 201. The fastening mechanism 3 includes a first shaped member 301, with a second shaped member 302 provided on one side of the first shaped member 301. The nut can be loosened from the threaded shaft by simply turning the nut. The nut leaves the surface of the first shaped member 301, releasing the fastening effect of the first connecting component 305 and the second connecting component 306, and the tube is completely loosened.

[0037] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a first connecting component 305 is provided on one side of the top of the first special-shaped member 301, and the top of the first special-shaped member 301 is connected to one end of the second special-shaped member 302 through the first connecting component 305, and the horizontal body of the first special-shaped member 301 is provided with a second connecting component 306, and the first special-shaped member 301 is connected to the other end of the second special-shaped member 302 through the second connecting component 306.

[0038] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a vertically arranged horizontal square tube 303 and a limiting square tube 304 are clamped between the first special-shaped part 301 and the second special-shaped part 302. The limiting square tube 304 provides vertical pipe positioning, and the horizontal square tube 303 is used to connect other ridge-building components.

[0039] Reference Figures 1-4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the first connecting component 305 includes two threaded blocks provided on the first special-shaped member 301 and the second special-shaped member 302, and the two threaded blocks are threadedly connected with a threaded shaft, one end of the threaded shaft of the first connecting component 305 is fixedly connected to the limiting block, and the other end of the first connecting component 305 is threadedly connected to a structural nut, and the second connecting component 306 includes a threaded shaft passing through the first special-shaped member 301 and the second special-shaped member 302, and one end of the threaded shaft of the second connecting component 306 is fixedly connected to the limited block. The second connecting component 306 has a structural nut threaded on the other end. By setting the fastening mechanism 3, the first connecting component 305 can fasten the vertical parts of the first special-shaped part 301 and the second special-shaped part 302, which is convenient for disassembly. When a pipe in a certain part of the connecting pipe system is damaged or needs to be repaired, the damaged part can be easily removed by using the fastened connection pipe for replacement or repair. During the installation process, if it is found that the position or angle of the pipe needs to be adjusted, the fastened connection method can be easily disassembled and reinstalled.

[0040] Specifically, the working process or working principle of the angle adjustment device for the ridge builder is as follows: when in use, the gear sleeve 207 is lifted upward, the gear sleeve 207 leaves the outer teeth 206, and the limiting effect of the horizontal first rotation direction of the main sleeve is contacted to adjust the angle of the rotary tiller 205. After the adjustment is completed, it is only necessary to put down the gear sleeve 207 to make the gear sleeve 207 and the outer teeth 206 re-engage, and continue to limit the main sleeve 1. For the fastening mechanism 3, it is only necessary to loosen the nut and the threaded shaft by rotating the nut. The nut leaves the surface of the first special-shaped part 301, so that the fastening effect of the first connecting component 305 and the second connecting component 306 is released to complete the loosening of the pipe.

[0041] It should be noted that the external teeth 206 are devices or equipment existing in the prior art, or devices or equipment that can be realized in the prior art, and can be selected as gears. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
