Description

Technical Field

[0001] The utility model relates to a sugarcane harvesting device, in particular to a self-propelled sugarcane cutter and paver, belonging to the technical field of agricultural machinery and equipment. Background Art

[0002] A sugarcane harvester is a device used to harvest sugarcane in a sugarcane field. It works by cutting the sugarcane in the field from the root and transporting all the harvested sugarcane to one side of the ridge, so that the sugarcane falls to one side and is spread horizontally on the ridge for easy collection and transportation. The sugarcane harvester is mainly composed of a sugarcane gathering mechanism, a sugarcane cutting mechanism and a conveying mechanism. The sugarcane gathering mechanism gathers the sugarcane to be harvested to the sugarcane cutting mechanism, the sugarcane cutting mechanism cuts the root of the sugarcane, and the conveying mechanism clamps and transports the cut sugarcane to one side of the ridge for output and then forms a local laying.

[0003] The height of the cutting disc of the existing sugarcane cutting mechanism of the sugarcane cutting machine from the ground, i.e., the cutting depth of the sugarcane, is pre-adjusted, but the plots of sugarcane planting land are often uneven, which causes the cutting disc with the adjusted height to easily cut too deep into the soil or not cut deep enough. If the blade cuts too deep into the soil, it is easy to damage the blade. If the cutting depth of the sugarcane is not enough, it will increase the head breakage rate of the sugarcane perennial roots, affect the growth of sugarcane in the next year, cause certain losses, and reduce the sugarcane harvest. In addition, the conveying mechanism of the existing sugarcane cutting machine generally adopts chain clamp conveying, that is, a pair of chains with fingers are used to convey the sugarcane together. Chain clamp conveying is easy to damage the sugarcane or the sugarcane epidermis. If the damaged sugarcane cannot be sent to the sugar factory for sugar extraction in time, it will deteriorate and cause a decrease in sugar content. Utility Model Content

[0004] The utility model aims to provide an improved self-propelled sugarcane cutter and paving machine to solve the above-mentioned shortcomings of the existing sugarcane cutter and paving machines.

[0005] The specific technical solution of the utility model is as follows:

[0006] A self-propelled sugarcane cutter and paving machine is provided with a walkable chassis, a body frame is provided above the chassis, a cab and a power system are provided above the body frame, a cutter and paving machine is provided at the front end of the body frame in a lower position in front of the cab, the cutter and paving machine is provided with an independent frame for support, the rear end of the frame of the cutter and paving machine is hinged to the front end of the body frame by a hinge, and a turning cylinder is provided between the body frame and the frame of the cutter and paving machine, the turning cylinder controls the whole cutter and paving machine to turn around a hinge point at the front end of the body frame within a certain angle range, thereby adjusting the pitch angle of the cutter and paving machine.

[0007] The frame of the mowing and paving machine is provided with a sugarcane gathering mechanism, a sugarcane cutting mechanism and a conveying mechanism, wherein the sugarcane gathering mechanism is arranged at the front end, the conveying mechanism is arranged behind the sugarcane gathering mechanism, the sugarcane inlet of the conveying mechanism is located in the middle of the mowing and paving machine and is connected with the sugarcane outlet of the sugarcane gathering mechanism, the sugarcane outlet of the conveying mechanism is tilted and raised to extend to the left or right side of the mowing and paving machine, and the sugarcane cutting mechanism is located below the sugarcane inlet of the conveying mechanism; the sugarcane cutting mechanism is provided with a cutting disc which is tilted and installed with a lower front and a higher rear, the cutting disc is provided with a connecting rod mechanism hinged on the frame, and a lifting cylinder is provided between the connecting rod mechanism and the frame, the lifting cylinder drives the connecting rod mechanism to deflect to drive the lifting and lowering of the cutting disc; the lifting cylinder adopts a flexible cylinder which can be elastically extended and retracted within a certain range.

[0008] The conveying mechanism is provided with a conveying clamping component, which is provided with two front and rear conveying chain rings in the same inclined plane, the two conveying chain rings extend unilaterally obliquely from the middle of the mowing and paving machine to the upper left or right side of the mowing and paving machine, and the adjacent side chain segments between the front and rear conveying chain rings jointly enclose to form an L-shaped bending channel, and the peripheries of the two conveying chain rings are fixedly connected with densely distributed soft wide rubber paddles that move synchronously with the conveying chain rings, and the rubber paddles on the peripheries of the two conveying chain rings are oppositely distributed and partially overlapped in the L-shaped bending channel, and the two conveying chain rings are respectively provided with hydraulic motors to drive them to rotate in opposite directions at the same speed, so that the L-shaped bending channel forms a sugarcane conveying channel for clamping and conveying sugarcane by two groups of oppositely distributed rubber paddles, the sugarcane inlet of the sugarcane conveying channel is in the middle of the mowing and paving machine and is connected with the sugarcane outlet of the sugarcane gathering mechanism, and the sugarcane outlet of the sugarcane conveying channel is on the left or right side of the mowing and paving machine, which is consistent with the direction of the unilateral oblique extension of the conveying chain ring.

[0009] The conveying mechanism is also provided with a limit clamping component, which has a limit chain ring at a position corresponding to the position below the rear transmission chain ring. The periphery of the limit chain ring is fixedly connected with limit fingers that are distributed at intervals and move synchronously with the limit chain ring. The limit chain ring is also driven by the hydraulic motor of the rear transmission chain ring through a coaxial connection. A lower guide baffle is provided in front of the limit chain ring, and the front chain segment of the limit chain ring and the lower guide baffle together form a lower limit clamping channel with the same direction at a position below the sugarcane feeding channel.

[0010] The advantages of this self-propelled sugarcane cutter and paving machine are: the machine has a fast transmission speed, does not block sugarcane, has high operating efficiency, and has good harvest quality. Since the lifting cylinder of the sugarcane cutting mechanism of this machine adopts a flexible cylinder that can be elastically extended within a certain range, the cutting disc of the sugarcane cutting mechanism can still float within a certain range according to the ups and downs of the plot after the height is adjusted by the lifting cylinder. Therefore, the blade will not cut too deep into the soil or the sugarcane cutting depth will not be enough. It is not easy to damage the blade, and it can ensure sufficient sugarcane cutting depth and reduce the head breakage rate of sugarcane perennial roots. Since the conveying mechanism of this machine adopts soft and wide rubber paddles to flexibly clamp and convey the harvested sugarcane, it is not easy to clamp the sugarcane or damage the sugarcane skin during the conveying process, and the conveying effect is better than the conventional chain clamping type.

[0018] The frame 5.1 of the cutting and paving machine 5 is provided with a sugarcane gathering mechanism 5.2, a sugarcane cutting mechanism 5.3 and a conveying mechanism 5.4, wherein the sugarcane gathering mechanism 5.2 is arranged at the front end, and the conveying mechanism 5.4 is arranged behind the sugarcane gathering mechanism 5.2, the sugarcane inlet of the conveying mechanism 5.4 is located in the middle of the cutting and paving machine 5 and is connected with the sugarcane outlet of the sugarcane gathering mechanism 5.2, the sugarcane outlet of the conveying mechanism 5.4 is tilted and raised to the left or right side of the cutting and paving machine 5, and the sugarcane cutting mechanism 5.3 is located below the sugarcane inlet of the conveying mechanism 5.4; the sugarcane cutting mechanism 5.4 is provided with a cutting disc 7 which is tiltedly installed with a lower front and a higher rear, the cutting disc 7 is provided with a connecting rod mechanism 8 which is hinged on the frame 5.1, and a lifting cylinder 9 is provided which is connected between the connecting rod mechanism 8 and the frame 5.1, and the lifting cylinder 9 drives the connecting rod mechanism 8 to deflect to drive the lifting and lowering of the cutting disc 7; the lifting cylinder 9 adopts a flexible cylinder which can be elastically extended within a certain range.

[0019] Furthermore, a return spring 9.1 is provided between the piston and the cylinder bottom in the cylinder body of the lifting cylinder 9. Figure 4 When in use, after the piston rod of the lifting oil cylinder 9 is hydraulically driven to a corresponding extension length, it can achieve a corresponding small elastic contraction according to the size of the resistance when encountering resistance, and can achieve elastic extension and reset after the resistance is removed.

[0020] The conveying mechanism 5.4 is provided with a conveying clamping component 10, and the conveying clamping component 10 is provided with two front and rear conveying chain rings 10.1 in the same inclined plane, and the two conveying chain rings 10.1 extend from the middle of the mowing and paving machine 5 to the upper left or right side of the mowing and paving machine 5. The adjacent side chain segments between the front and rear conveying chain rings 10.1 are jointly enclosed to form an L-shaped bending channel, and the outer peripheries of the two conveying chain rings 10.1 are fixedly connected with soft wide rubber paddles 10.2 which are densely distributed and move synchronously with the conveying chain rings 10.1. The rubber paddles 10.2 on the outer peripheries of the two conveying chain circles 10.1 in the folding channel are oppositely distributed and partially overlapped. The two conveying chain circles 10.2 are respectively provided with hydraulic motors 11 to drive them to rotate in opposite directions at the same speed, so that the L-shaped bending channel forms a sugarcane conveying channel for clamping and conveying sugarcane by two groups of oppositely distributed rubber paddles 10.2. The sugarcane inlet of the sugarcane conveying channel is in the middle of the cutting and paving machine 5 and is connected with the sugarcane outlet of the sugarcane gathering mechanism 5.2. The sugarcane outlet of the sugarcane conveying channel is on the left or right side of the cutting and paving machine 5, which is consistent with the direction in which the conveying chain circle 10.1 extends unilaterally and tiltedly.

[0022] The conveying mechanism 5.4 is also provided with a limit clamping component 12. The limit clamping component 12 is provided with a limit chain ring 12.1 at a position corresponding to the lower portion of the rear conveying chain ring 10.1. The outer periphery of the limit chain ring 12.1 is fixedly connected with limit fingers 12.2 which are distributed at intervals and move synchronously with the limit chain ring 12.1. The limit chain ring 12.1 is also driven by the hydraulic motor 11 of the rear conveying chain ring 10.1 through a coaxial connection. A lower guide baffle 13 is provided in front of the limit chain ring 12.1. The front chain segment of the limit chain ring 12.1 and the lower guide baffle 13 together form a lower limit clamping channel with the same direction at a position below the sugarcane conveying channel.

[0023] The conveying mechanism 5.4 is also provided with a pair of upper guide bars 14 arranged front and rear above the sugarcane conveying passage of the conveying clamping component 10, and an upper limit passage with the same direction is formed between the two upper guide bars 14 at the position above the sugarcane conveying passage.

[0024] The support frame of the frame 5.1 of the mower and paving machine 5 on the side corresponding to the sugarcane outlet of the conveying mechanism 5.4 is set as a sinking U-shaped frame 5.1a to avoid interference with the conveying mechanism 5.4 and the sugarcane vertically clamped and conveyed by the conveying mechanism 5.4.

[0025] The sugarcane gathering mechanism 5.2 is provided with two left and right sugarcane gathering chain rings 15 which are located in the same backward inclined plane. The two sugarcane gathering chain rings 15 extend obliquely from the lower end of the front end of the mowing and paving machine 5 to the rear and upper end. The adjacent side chain sections between the left and right sugarcane gathering chain rings 15 jointly enclose and form an "eight"-shaped channel which is wide at the bottom and narrow at the top. The outer peripheries of the two sugarcane gathering chain rings 15 are fixedly connected with sugarcane gathering fingers 15.1 which are distributed at intervals and move synchronously with the sugarcane gathering chain rings 15. The two sugarcane gathering chain rings 15.1 are respectively provided with hydraulic motors 11 to drive them to rotate in opposite directions at the same speed, so that the "eight"-shaped channel forms a sugarcane gathering channel for gathering and conveying sugarcane by the chains and sugarcane gathering fingers 15.1 arranged in opposite directions. The lower front of the sugarcane gathering channel is a sugarcane inlet, and the upper rear part is a sugarcane outlet.

[0026] The chassis 1 adopts a crawler chassis so that the whole machine is more suitable for traveling in an undulating sugarcane field.

[0027] When the self-propelled sugarcane cutter and paving machine is in operation, the chassis 1 drives the whole machine to move, the cutting and paving machine 5 at the front end is aligned with the sugarcane row to be harvested, and the machine moves forward at the operating speed, the sugarcane enters from the sugarcane inlet of the sugarcane gathering mechanism 5.2 of the cutting and paving machine 5, the sugarcane is gathered and sorted by the sugarcane gathering chain ring 15 and the sugarcane gathering finger 15.1 of the sugarcane gathering mechanism 5.2, so that the sugarcane enters the cutting blade 7 of the cutting blade mechanism 5.3 in an orderly manner, and the cutting blade 7 cuts the sugarcane from the bottom, and after the sugarcane is cut, it is sent to the sugarcane inlet of the conveying mechanism 5.4 from the sugarcane outlet of the sugarcane gathering mechanism 5.2 in a vertical state, and in the conveying mechanism 5.4, two groups of rubber paddles 10.2 of the sugarcane feeding channel of the conveying clamping component 10 are sent to the middle of the sugarcane. The sugarcane is stably and flexibly clamped and conveyed. At the same time, the limiting chain ring 12.1, the limiting finger 12.2 and the lower guide baffle 13 of the lower limiting clamping channel of the limiting clamping component 12 jointly limit the middle and lower part of the sugarcane for loose clamping and conveying. The two upper guide baffles 14 of the upper limiting channel jointly limit the conveying of the middle and upper part of the sugarcane, so that the sugarcane is kept upright and conveyed in an orderly manner. Since the sugarcane conveying channel in the conveying mechanism 5.4 is inclined and raised to the side of the cutting and paving machine 5, the sugarcane can be lifted upward during the clamping and conveying process, so that the lower end of the sugarcane can avoid the corresponding frame. Finally, the sugarcane is output vertically from the sugarcane outlet of the conveying mechanism 5.4 and falls to one side, thereby the harvested sugarcane can be neatly and orderly spread horizontally on the sugarcane ridge.

[0028] The above-mentioned figures are only typical embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
