[0002] Sugarcane is an important sugar crop in my country. It is mainly planted in hilly and mountainous areas such as Guangdong, Guangxi and Yunnan. The sugarcane fields are undulating and there is a lot of rain during the harvest season. The working environment greatly limits the quality and time of the work. The traditional way of harvesting sugarcane is to cut the sugarcane on the ground. However, this harvesting method leaves sugarcane piles on the ground, which reduces the yield of sugar cane. In addition, the cut is uneven and easy to break, which increases the harvesting loss and affects the germination rate of the next season. The current development direction is to harvest with the blade inserted into the soil. For this reason, the position of the harvesting knife of a general harvester is fixed to ensure that the blade can effectively enter the soil for cutting. However, this harvester needs to turn around and return to the origin every time before the next round of harvesting can be carried out, which is inefficient. Summary of the invention

[0003] The utility model aims to provide a bidirectional inclined ploughing device and a harvester, which can keep the knife head inclined on the basis of rotating the direction of the harvesting knife, so as to realize flexible ploughing between ridges.

[0030] like Figure 1-5 As shown, the bidirectional inclined earth-entering harvester of this embodiment includes a trailer and a bidirectional inclined earth-entering harvesting device installed on the trailer.

[0031] The bidirectional inclined in-soil harvesting device comprises: a rotating seat 100, which is used to be installed on a trailer; a harvesting knife platform 200, which comprises a blade 210 and a driving mechanism 220 for driving the blade 210 to rotate, and there is an acute angle β between the rotating surface of the blade 210 and the horizontal plane; wherein the harvesting knife platform 200 is rotatably connected to the rotating seat 100, and there is an acute angle α between the harvesting knife platform 200 and the vertical line relative to the rotating axis G of the rotating seat 100, which means that after the rotating seat 100 is installed on the harvester, there is an acute angle between the harvesting knife platform 200 and the vertical line relative to the rotating axis G of the rotating seat 100. The rotating axis G of the harvesting knife platform 200 is inclined, and the blade 210 is inclined forward and downward, so that no matter whether the harvesting knife platform 200 rotates to the left or right position, the blade 210 maintains a forward and downward tilted posture, which is convenient for piercing into the ground to realize in-soil harvesting. In this embodiment, the harvesting blade 200 can be rotated to the left or rear side of the trailer relative to the rotating seat 100. For example, when the harvesting blade 200 is rotated to the right side of the trailer, after harvesting the first ridge of sugarcane on the right side of the harvester, the harvester turns around and rotates the harvesting blade 200 to the left side. The harvester can then go back to harvest the second ridge of sugarcane on the left side of the harvester without returning to the origin to harvest the sugarcane on the right side of the harvester. The angle α and the angle β can be the same or different, and the appropriate angle can be selected according to the undulation of the field and the depth of the soil.

[0032] The utility model has high harvesting efficiency, and because the rotating axis G is tilted, no matter the harvesting knife platform 200 rotates to the left or right position, the blade 210 always tilts forward and downward, ensuring that the blade 210 penetrates into the ground to achieve in-soil harvesting. The blade head is kept tilted on the basis of the direction of rotating the harvesting knife, so as to achieve flexible in-soil harvesting between ridges.

[0033] The drive mechanism 220 is provided with a knife shaft 221, and the blade 210 is installed on the knife shaft 221. The rotation axis H of the knife shaft 221 has an acute angle relative to the plumb line. The knife shaft 221 is provided with a knife disc 222, and the knife disc 222 is inclined forward and downward relative to the horizontal plane, and has an acute angle β. The blade 210 is installed on the knife disc 222. The knife shaft 221 is inclined, and the knife disc 222 is inclined. The blade 210 is installed flat against the knife disc 222. There is an acute angle β between the rotation surface of the blade 210 and the horizontal plane. The knife disc 222 provides strength support for the blade 210, and improves the durability of the blade 210 on the basis of ensuring that the blade 210 cuts into the soil.

[0034] The harvesting tool platform 200 also includes a rotating plate 230, a first connecting rod 240, a mounting plate 250, and a second connecting rod 260 which are hinged in sequence end to end. The rotating plate 230, the first connecting rod 240, the mounting plate 250, and the second connecting rod 260 constitute a movable four-link component. The mounting plate 250 is rotatably mounted on the rotating seat 100, and the driving mechanism 220 is mounted on the mounting plate 250.

[0035] The four-link member is provided with a telescopic cylinder 270, which is used to drive the four-link member to deform, thereby controlling the lifting and lowering of the driving mechanism 220. When it is necessary to harvest sugarcane, the blade 210 is lowered to the ground to harvest the sugarcane in the ground. When driving or transporting, the blade 210 is lifted above the ground to avoid the loss of the blade 210.

[0036] The first connecting rod 240 includes two ear plates 241 arranged at intervals. The rotating plate 230 is inserted between the two ear plates 241 and is rotatably connected with the ear plates 241. The rotating plate 230 is provided with a positioning portion 231. When the first connecting rod 240 rotates relative to the rotating plate 230, the positioning portion 231 can be received between the two ear plates 241 without affecting the lifting and lowering of the four-bar linkage component.

[0037] The positioning portion 231 is provided with a first positioning hole 232, and the rotating seat 100 is provided with at least two second positioning holes 111 and a positioning pin 113. In this embodiment, a positioning plate 110 is provided on the top of the rotating seat 100, and the positioning plate 110 is provided with three second positioning holes 111, which correspond to the left position, the middle position, and the right position respectively. When the rotating plate 230 rotates, the first positioning hole 232 can overlap with any second positioning hole 111, and the positioning pin 113 can be detachably inserted into the first positioning hole 232 and the corresponding second positioning hole 111. The positioning pin 113 can temporarily limit the position of the harvesting knife table 200 to prevent the harvesting knife table 200 from deflecting and causing damage during the harvesting process. Since the positioning pin 113 is provided at the top, the driver can operate it by turning around, and the positioning pin 113 can be quickly pulled out or inserted when changing the position of the harvesting knife table 200.

[0038] The rotating seat 100 includes a stand 160, ribs 150 arranged on both sides of the stand 160, an upper mounting plate 130 arranged on the upper part of the stand 160, and a lower mounting plate 140 arranged on the lower part of the stand 160. The positioning plate 110 is arranged above the upper mounting plate 130. The rotating seat 100 is connected to the harvesting knife platform 200 through a rotating shaft, and the rotating shaft includes an upper rotating shaft 131 and a lower rotating shaft 141. The rotating connection between the rotating seat 100 and the harvesting knife platform 200 is stored between the two ribs 150. The upper and lower ends of the rotating plate 230 are respectively rotatably connected to the upper mounting plate 130 and the lower mounting plate 140 through the upper rotating shaft 131 and the lower rotating shaft 141, and the rotating plate 230 is stored between the two ribs 150. The upper and lower two-point connection method provides good structural strength for the tilting setting of the rotating plate 230. When the rotating plate 230 rotates, it is limited by the two ribs 150 to avoid over-limit.

[0039] The rotating seat 100 is installed on the trailer. One side of the rotating seat 100 is an assembly surface 120, and the assembly surface 120 is used for installation against the trailer. The harvesting knife table 200 is at an acute angle α with the assembly surface 120 relative to the rotation axis G of the rotating seat 100. A support is provided at the rear of the trailer, and the support is provided with a plumb surface. The assembly surface 120 of the rotating seat 100 is installed on the plumb surface of the support. General connection standard parts come with horizontal reference planes or plumb reference planes. When the harvesting device of the utility model is installed on the trailer, it is connected through the connection standard parts. Since the rotation axis of the rotating seat 100 is tilted, it can be directly installed on the connection standard parts through the assembly surface 120. The use of universal standard parts can save costs and can be quickly installed on existing trailers.

[0040] 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.
