Description

Technical Field

[0001] This utility model relates to the field of sugarcane shearing technology, and more specifically to an electrically controlled sugarcane shearing that is beneficial to increasing yield. Background Technology

[0002] Sugarcane is a temperate and tropical crop and a raw material for sugar production. Harvesting sugarcane involves cutting off the bottom of the stalk. Currently, to improve harvesting efficiency, sugarcane shears have been designed. These shears are electric devices with a cutting body, an extension rod, and a handle. When shearing, the user holds the handle, which has a trigger. Pulling the trigger drives the cutting body to complete the cutting action. The extension rod design eliminates the need for bending over to cut the sugarcane, significantly improving work efficiency.

[0003] In the prior art, Chinese patent with publication number CN214902195U discloses a new type of sugarcane shear, which can achieve convenient cutting function. However, in the actual cutting process, soil will adhere to the shear body, which will cause a certain degree of pollution when cutting sugarcane. Moreover, when not in use, the shear body is exposed to the outside, which can easily cause injury to workers when handling it. Utility Model Content

[0022] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0024] Specifically, an electrically controlled sugarcane shear that improves yield includes a fixed shaft 1 and a body 9. A handle 5 is mounted on the top of the fixed shaft 1 via a telescopic assembly. A base plate 7 is fixedly installed on the bottom of the fixed shaft 1, and a rod 8 is fixedly installed on the bottom of the base plate 7. A spline hole is formed on the outer periphery of the fixed shaft 1, and a pin 10 is slidably installed within the spline hole. The body 9 is fixedly installed at one end of the pin 10, and a pressing plate 11 is fixedly installed at the other end of the pin 10. A reset assembly is provided on the side of the pressing plate 11. A protective shell 13 is fixedly installed on the top of the base plate 7. 9 is movably installed inside the protective shell 13. The protective shell 13 is provided with a cleaning component adapted to the main body 9. The cleaning component includes two cleaning shafts 14. A rectangular cavity is opened inside the protective shell 13. One end of each of the two cleaning shafts 14 is rotatably installed on the inner side wall of the rectangular cavity and connected to each other through a transmission unit. A transmission cavity is opened inside the protective shell 13. The other end of each of the two cleaning shafts 14 is rotatably installed on the inner side wall of the transmission cavity. A rotating unit is provided on one of the cleaning shafts 14. Cleaning roller brushes 15 are fixedly sleeved on the outer periphery of both cleaning shafts 14.

[0025] With the above structure, during use, the base plate 7 is placed on the ground, and the insertion rod 8 is inserted into the soil to limit the base plate 7. The foot is used to squeeze the pressing plate 11, thereby driving the pressing plate 11, the pin shaft 10, and the body 9 to move synchronously. This causes the body 9 to move outside the protective shell 13 and align with the sugarcane. Then, the body 9 cuts the sugarcane. In this configuration, the protective shell 13 protects the body 9 in normal conditions, preventing the body 9 from being exposed to the outside and causing scratches to the user when handling it. After the sugarcane is cut, the limiting of the pressing plate 11 is released, and the pressing plate 11, the pin shaft 10, and the body 9 are synchronously reset under the action of the reset component. When the pressing plate 11 is reset, it can drive one of the cleaning shafts 14 to rotate under the action of the rotating unit, and drive the other cleaning shaft 14 to rotate in the opposite direction through the action of the transmission unit. This causes the two cleaning roller brushes 15 to rotate synchronously in opposite directions, cleaning the soil on the body 9 and preventing the sugarcane from being contaminated by soil residue on the body 9 during subsequent cutting.

[0026] like Figure 2 As shown, the telescopic assembly includes a telescopic shaft 2, a telescopic groove is provided at the top of the fixed shaft 1, the telescopic shaft 2 is slidably installed in the telescopic groove, a threaded hole is provided on the inner wall of the telescopic groove, and multiple threaded grooves 4 are provided on the outer wall of the telescopic shaft 2. A fixing bolt 3 is threadedly installed in the threaded hole and one of the threaded grooves 4. A handle 5 is fixedly sleeved on the top of the telescopic shaft 2, and a trigger 6 is provided on the inner wall of the handle 5. The trigger 6 is electrically connected to the body 9.

[0027] In this implementation scheme, when it is necessary to adjust the height of the telescopic shaft 2, the limiting of the telescopic shaft 2 can be released by removing the fixing bolt 3, and then the telescopic shaft 2 can be slid so that the corresponding thread groove 4 is aligned with the thread hole. Then the telescopic shaft 2 is fixed again by the fixing bolt 3, thereby realizing the height adjustment of the telescopic shaft 2, which is convenient to adapt to operators of different heights.

[0028] like Figure 3 As shown, the reset assembly includes a reset spring 12, which is sleeved on the outer peripheral wall of the pin 10. The outer peripheral wall of the fixed shaft 1 is provided with a mounting groove. One end of the reset spring 12 is fixedly installed on the inner end wall of the mounting groove, and the other end of the reset spring 12 is fixedly installed on the side of the extrusion plate 11.

[0029] In this embodiment, when the operator applies a pushing force to the pressing plate 11, it can press the return spring 12. When the limit on the pressing plate 11 is released, the elastic action of the return spring 12 can drive the pressing plate 11 to achieve the reset function, thereby driving the main body 9 to reset synchronously through the connection action of the pin 10.

[0030] like Figure 3 and Figure 4 As shown, the transmission unit includes two transmission gears 16, which are respectively fixedly sleeved on the peripheral outer walls of the two cleaning shafts 14, and the two transmission gears 16 are meshed together.

[0031] In this embodiment, by setting two transmission gears 16, when one cleaning shaft 14 rotates, it can drive the other cleaning shaft 14 to rotate synchronously in the opposite direction through the meshing of the two transmission gears 16, thereby causing the two cleaning roller brushes 15 to rotate synchronously in the opposite direction.

[0032] like Figure 5 and Figure 6 As shown, the rotating unit includes a rotating shaft 17, with its two ends rotatably mounted on opposite inner walls of the transmission cavity. A rotating gear 18 is fixedly sleeved on the outer circumferential wall of the rotating shaft 17. A spur rack 19 is slidably mounted inside the transmission cavity via a limiting element, and the spur rack 19 meshes with the rotating gear 18. The rotating unit also includes two synchronous pulleys 22, which are fixedly sleeved on the rotating shaft 17 and one of the cleaning shafts 14, respectively. A synchronous belt 23 is meshed on both synchronous pulleys 22.

[0033] In this embodiment, by setting up the rack 19 and the rotating gear 18, the rack 19 can drive the rotating shaft 17 to rotate during horizontal movement through its meshing with the rotating gear 18. Then, under the meshing of the two synchronous pulleys 22 and the synchronous belt 23, the cleaning shaft 14 is driven to rotate.

[0034] like Figure 5 and Figure 6 As shown, the limiting element includes a T-shaped limiting strip 20. Rectangular holes are provided on the opposite inner walls of the transmission cavity. The two rectangular holes and the top inner wall of the transmission cavity are provided with a T-shaped groove. The T-shaped limiting strip 20 is slidably installed in the T-shaped groove. The bottom of the T-shaped limiting strip 20 is fixedly connected to the top of the rack 19. An extrusion shaft 21 is fixedly installed on the side of the rack 19. The other end of the extrusion shaft 21 is fixedly connected to the side of the extrusion plate 11.

[0035] In this embodiment, the extrusion shaft 21 enables the extrusion plate 11 to move synchronously with the rack 19 through the connection of the extrusion shaft 21. Furthermore, the T-shaped groove and T-shaped limiting strip 20 limit the rack 19 to prevent it from falling off.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
