[0027] like Figure 1 As shown, the harvesting equipment includes a working device 2 and a walking body 1. The working device 2 is installed on the walking body 1, and the cutter 24 can swing to the left or right side of the walking body 1 to achieve double-sided harvesting.

[0028] like Figure 2-5 As shown, the working device 2 for harvesting equipment includes: an inner cylinder 10 and an outer cylinder 20. One end of the inner cylinder 10 is provided with a rotatable transmission wheel 12. The outer cylinder 20 is rotatably sleeved outside the inner cylinder 10. The rotation axis of the outer cylinder 20 is coaxial with the rotation axis of the transmission wheel 12. The outer cylinder 20 is provided with a cantilever 21. The cantilever 21 is provided with a rotatable driven wheel 23 and a cutter 24 connected to the driven wheel 23. The transmission wheel 12 and the driven wheel 23 are connected by a transmission belt 30. The transmission belt 30 is used for transmission. The transmission belt 30 is wound around the transmission shaft 11 and the rotating shaft. The form of the transmission belt 30 includes but is not limited to a chain, a chain belt, a metal belt, a rubber belt, etc. The inner cylinder 10 of the working device 2 is installed on the walking body 1. The outer cylinder 20 can rotate relative to the inner cylinder 10 to drive the cutter 24 to the left or right side of the forward direction of the walking body 1. The utility model uses the transmission wheel 12 and the driven wheel 23 to cooperate with the transmission belt 30 for transmission. When the outer cylinder 20 rotates around the inner cylinder 10, the cutter 24 swings accordingly, but does not affect the transmission of the transmission belt 30. The cutter 24 keeps rotating normally and harvests the crops normally. The utility model uses a simple structure to achieve left and right swings of the cutter 24 without stopping the machine, and realizes double-sided harvesting. It is suitable for operations on small plots, improves harvesting efficiency, and also reduces the volume and weight of the harvesting equipment, making it easy to transport. Farmers can use agricultural vehicles to transport it, which is convenient and practical.

[0029] A rotatable transmission shaft 11 is provided in the inner cylinder 10, and the transmission shaft 11 is connected to the transmission wheel 12. The cantilever 21 is provided with a rotatable driven shaft 22, and the driven shaft 22 is connected to the driven wheel 23. The transmission shaft 11 and the driven shaft 22 are parallel. In this embodiment, the transmission shaft 11 and the driven shaft 22 are provided to realize the rotation of the transmission wheel 12 and the driven wheel 23. The overall structure is stable and the rotation is stable, which is particularly suitable for the structure of the cantilever 21 provided in this embodiment. In addition, agricultural machinery uses a large number of belts, and the maintenance of the belts is highly versatile, and the loading and unloading is simple, and no special training is required.

[0030] The present embodiment further comprises a right angle gearbox 40, the output end of the right angle gearbox 40 is connected to the transmission shaft 11, the input end of the right angle gearbox 40 is connected to the output end of the engine 50, and the engine 50 and the outer cylinder 20 are located on the same side of the right angle gearbox 40. Figure 3 As shown, the engine 50 and the outer cylinder 20 are both located below the right-angle gearbox 40 (the description here includes the situation of being directly below and not directly below). This design can lower the center of gravity height of the engine 50, make full use of the space, and reduce the overall volume of the harvesting equipment.

[0031] The inner cylinder 10 is provided with an upper flange 13 and a lower flange 14, and the outer cylinder 20 is located between the upper flange 13 and the lower flange 14. The upper flange 13 is connected to an upper bracket 131, and the lower flange 14 is connected to a lower bracket 141. The upper bracket 131 and the lower bracket 141 are used to install the working device 2 to the harvesting equipment, and the upper and lower installation positions are more secure.

[0032] Specifically, the upper end of the inner cylinder 10 extends from the upper end of the outer cylinder 20, and the lower end of the inner cylinder 10 extends from the lower end of the outer cylinder 20. The transmission shaft 11 is installed in the inner cylinder 10 through a bearing. The lower end of the transmission shaft 11 extends from the lower end of the inner cylinder 10 and passes through the through hole of the lower flange 14. The lower end of the transmission shaft 11 is provided with a transmission wheel 12, and the lower flange 14 is bolted to the lower end surface of the inner cylinder 10. The right angle gearbox 40 is located above the inner cylinder 10. The output end of the right angle gearbox 40 is coaxially connected with the upper end of the transmission shaft 11. The input end of the right angle gearbox 40 is provided with a first pulley 41. The output end of the engine 50 is provided with a second pulley 21. The first pulley 41 and the second pulley 21 are connected by a belt 60. The second pulley 21 is located below the first pulley 41. The second pulley 21 is located between the engine 50 and the outer cylinder 20, so that the center of gravity of the engine 50 is lowered, the structural layout is reasonable, and the overall volume is small. In this embodiment, the right angle gearbox 40 is at the upper end of the inner cylinder 10, and the cutter 24 is at the lower end of the inner cylinder 10, which is suitable for cutting crops from low places, such as sugarcane, rice, wheat harvesting, etc., but it is not limited to this embodiment, and it can also be designed that the right angle gearbox 40 is at the lower end of the inner cylinder 10 and the cutter 24 is at the upper end of the inner cylinder 10, which is suitable for cutting crops from high places, such as sunflower harvesting, crop tipping, etc. In this embodiment, the first pulley 41 and the second pulley 21 are used to realize the connection between the engine 50 and the right angle gearbox 40 through the belt 60 transmission, which is simple to maintain and light in weight, but it is not limited to this embodiment, and other methods can also be used to connect the engine 50 and the right angle gearbox 40, including but not limited to gear sets and universal shafts.

[0033] like Figure 2 As shown, the side wall of the outer cylinder 20 is provided with a circumferentially extending slot 26, and the outer wall of the inner cylinder 10 is provided with a limiting protrusion 15, which is inserted into the slot 26, and the limiting protrusion 15 and the slot 26 are slidably matched. Figure 2 As shown, the groove 26 extends along the circumferential direction of the cross section of the outer cylinder 20 on the side wall of the outer cylinder 20. When the outer cylinder 20 rotates, the limiting protrusion 15 slides in the groove 26 without affecting the normal rotation of the outer cylinder 20. Since the limiting protrusion 15 can only move in the groove 26, under the restriction of the groove 26, the rotation angle of the outer cylinder 20 relative to the inner cylinder 10 is constrained within a certain range to avoid damage caused by excessive rotation angle.

[0034] The inner cylinder 10 is provided with a limit plate 16 and a limit pin 17. The limit plate 16 is provided with a limit hole 18. The outer cylinder 20 or the cantilever 21 is provided with an insertion hole 25. The limit pin 17 can be detachably inserted into the limit hole 18 and the insertion hole 25. When the limit pin 17 is inserted into the limit hole 18 and the insertion hole 25, the position of the cantilever 21 can be limited, thereby limiting the position of the tool 24. The upper flange 13 is installed at the position where the upper end of the inner cylinder 10 extends out of the outer cylinder 20, and the limit plate 16 is sleeved on the outer side of the inner cylinder 10 and installed on the upper flange 13. In this embodiment, the insertion hole 25 is provided on the cantilever 21. However, it is not limited to this embodiment, and the insertion hole 25 can also be provided on the outer cylinder 20.

[0035] In this embodiment, the limiting plate 16 is provided with at least two limiting holes 18, and the insertion hole 25 can be aligned with any limiting hole 18. Different insertion holes 25 and limiting holes 18 can be used to position the cantilever 21 at different angles. Preferably, in this embodiment, the cantilever 21 can be positioned in the front (such as Figure 4 As shown), left side, right side (as shown Figure 5 As shown in the figure, the outer cylinder 20 or the cantilever 21 has at least two insertion holes 25, and the limiting hole 18 can be aligned with any insertion hole 25.

[0036] like Figure 1 As shown, when the working device 2 is installed on the walking body 1, the outer cylinder 20 and the inner cylinder 10 are tilted relative to the road surface, and the upper ends of the outer cylinder 20 and the inner cylinder 10 are tilted forward along the forward direction of the walking body 1. The transmission shaft 11 has the same tilt angle as the inner cylinder 10 and the outer cylinder 20, the rotation axis is parallel to the transmission shaft 11, the rotation surface of the cutter 24 is tilted relative to the horizontal plane, and the rotation front edge of the cutter 24 is tilted forward and downward, so that it can penetrate into the ground to cut the roots of the sugarcane, realize in-soil harvesting, avoid sugarcane bursting, and increase the budding rate and sugar yield rate. Since the transmission shaft 11 and the driven shaft 22 are arranged in parallel, when the cutter 24 is rotated to the left or right, the same tilt angle is still maintained to realize in-soil harvesting.

[0037] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
