[0028] Example 1

[0029] like Figures 1-5As shown, this utility model proposes an agricultural harvesting device, including a shovel handle 1, a shovel plate 4, and a drive assembly. The shovel handle 1 is integrally connected to a fixing plate 2, and the fixing plate 2 is connected to a rotating shaft 3. Two annular grooves 31 are symmetrically arranged on the rotating shaft 3, and two through holes 32 are provided on the rotating shaft 3. The through holes 32 on both sides are respectively connected to the annular grooves 31 on the corresponding sides. A first locking block 6 is provided in the annular groove 31 and slides radially along the rotating shaft 3. A blade 41 and a saw blade 42 are respectively provided on both sides of the shovel plate 4. Two ear plates 5 are symmetrically arranged on the shovel plate 4. A first locking groove 51 and a circular groove 52 coaxially connected to the first locking groove 51 are provided on the ear plates 5. The first locking groove 51 on the two ear plates 5 is located on the side of the circular groove 52 on the two ear plates 5 that is far away from each other, and the inner diameter of the circular groove 52 is larger than the inner diameter of the first locking groove 51. The rotating shaft 3 is rotatably connected to the inner wall of the circular groove 52, and the length of the rotating shaft 3 is greater than the distance between the two ear plates 5. The first slot 51 is an internal toothed groove, and the first locking block 6 is an external toothed disc. The first slot 51 and the first locking block 6 are fitted together. Two sets of drive components are symmetrically arranged on the rotating shaft 3 and drive the first locking blocks 6 on the corresponding sides.

[0030] In this embodiment, when the action of the shovel (shovel) needs to be changed to the action of the hoe, the driving components on both sides push the first locking block 6 to slide from the first locking groove 51 into the circular groove 52. At this time, the first locking block 6 is no longer engaged with the first locking groove 51, thereby releasing the rotation restriction between the ear plate 5 and the rotating shaft 3. After the shovel plate 4 is flipped to the required angle relationship with the shovel handle 1, the driving components reset and the first locking block 6 is re-engaged into the first locking groove 51 in the new position, thereby realizing the rotation restriction between the ear plate 5 and the rotating shaft 3. At this time, the shovel is transformed into a hoe. In this embodiment, the length of the rotating shaft 3 is greater than the distance between the two ear plates, and it can be seen from the attached figure that its overall length is relatively large. Therefore, when the rotating shaft 3 is used as a shovel in this device, the extended part of the rotating shaft 3 can be used as a foot pedal. The user can step on the rotating shaft to promote the insertion of the shovel plate 4 into the soil.

[0031] When needed

[0032] Example 2

[0033] like Figures 1-3 As shown, this embodiment discloses the specific structure of the driving component, which includes a first button 7. A slide groove 33 is provided on the rotating shaft 3. One end of the first button 7 is inserted into the slide groove 33 and slidably connected to its inner wall. The first button 7 is connected to a push rod 8, which is slidably connected to the rotating shaft 3. The end of the push rod 8 away from the first button 7 is inserted into the through hole 32 on the corresponding side and connected to the first locking block 6 on that side. A first spring 9 is provided in the slide groove 33, and both ends of the first spring 9 abut against the inner wall of the slide groove 33 and the first button 7, respectively.

[0034] In this embodiment, pressing the first button 7 pushes the push rod 8 to slide. At this time, the first spring 9 is compressed and accumulates potential energy. The push rod 8 pushes the first locking block 6 to slide. When the first locking block 6 slides completely from the first slot 51 into the circular groove 52, the rotating shaft 3 no longer acts as a rotation limiter on the ear plate 5. At this time, the angle of the shovel plate 4 can be adjusted. After releasing the button, the first spring 9 releases potential energy and pushes the first button 7 back. The first button 7 drives the push rod 8 and the first locking block 6 to slide back to their original positions. The first locking block 6 re-engages in the first slot 51 in the new position, thereby restoring the rotation limiter of the rotating shaft 3 on the ear plate 5.

[0035] Example 3

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, the agricultural harvesting device proposed in this utility model, compared with Embodiment 1 and Embodiment 2, further includes a movable handle 16 and a positioning component. One end of the movable handle 16 is inserted into the shovel handle 1 and slides radially therein. The positioning component is disposed on the shovel handle 1, and in the locked state, the positioning component restricts the relative sliding between the movable handle 16 and the shovel handle 1. The shovel handle 1 is provided with an insertion hole, one end of the movable handle 16 is inserted into the insertion hole and slidably connected to its inner wall, and a handle 17 is provided at the end of the movable handle 16 away from the shovel handle 1. The positioning component includes a limiting block 10, a slider 12, a second locking block 13, and a second button 14. The limiting block 10 is connected to the inner wall of the opening of the insertion hole, and the movable handle 16 is provided with a limiting hole 161. The limiting block 10 is located inside the limiting hole 161 and slidably connected to its inner wall. Several second locking grooves 162 are equidistantly arranged on both sides of the limiting hole 161 on the movable handle 16. A guide groove is provided on the limiting block 10, and a guide rod 11 is provided in the guide groove. The slider 12 is located in the guide groove and is slidably connected to the limiting block 10. The guide rod 11 passes through the slider 12 and is slidably connected to it. A second spring 15 is sleeved on the guide rod 11, and the two ends of the second spring 15 abut against the inner wall of the guide groove and the slider 12, respectively. The second locking block 13 is slidably connected to both the limiting block 10 and the shovel handle 1. The second locking block 13 is locked into the second locking groove 162 on the corresponding side. The second locking block 13 is connected to the slider 12, and the second button 14 is connected to the side of the slider 12 away from the second locking block 13.

[0037] In this embodiment, the movable handle 16 allows the shovel to be used by people of different heights. When not in use, the movable handle 16 can be inserted into the shovel handle 1 and hung by a hook or placed directly on the ground. To adjust the extension length of the movable handle 16, simply press the second button 14. The second button 14 pushes the slider 12 to slide, thereby causing the second locking block 13 to disengage from the second locking slot 162. At this time, the second spring 15 accumulates potential energy, and the movable handle 16 can slide arbitrarily along its radial direction within the shovel handle 1. After adjusting its length to the desired value, release the second button 14. The slider 12 will then slide in the opposite direction under the tension of the second spring 15. With appropriate fine-tuning of the movable handle 16, the second locking block 13 can be inserted into the nearest second locking slot 162.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
