Description

Technical Field

[0001] The utility model relates to the technical field of sugarcane harvesting machinery, in particular to a sugarcane cutting system with a soil covering function. Background Art

[0002] The cutting process in sugarcane harvesting is a key step in the entire harvesting process, which involves cutting off the sugarcane from the roots and collecting it. Before cutting the sugarcane, the harvester will use a spiral rod to straighten the fallen sugarcane to ensure that the sugarcane is upright and easy to cut. The knife disc of the sugarcane harvester is equipped with sharp blades. When the knife disc rotates, the blades quickly cut the sugarcane to achieve efficient harvesting. The cut sugarcane is transported to the channel device inside the machine through the rotation of the rotating shaft for leaf removal and separation, and then transported out for stacking and sorting. During the cutting process, it is important to protect the sugarcane ratoon, which helps to ensure the regeneration ability of the sugarcane and the yield of the next season. The cutting device of the sugarcane harvester is one of its core components and is mainly responsible for the cutting of sugarcane.

[0003] For example, in the cutting device of the patent application publication number CN108738675A, which is named as a sugarcane harvester, a hydraulic motor or an electric motor is used to drive the two drive shafts through a gear box. The cutter disc is fixed at the bottom of the drive shaft, and a number of blades are fixed on the cutter disc. The drive shaft drives the cutter disc to rotate. A pair of sleeves (feeding barrels) are also installed on the two drive shafts of the cutter. There are multiple rubber plates (feeding baffles) on the feeding barrel. The feeding barrel is driven by a special gear and is used to transport the sugarcane into the channel when it rotates. There are some problems with this technology:

[0004] 1. When cutting sugarcane, if the soil is cut into the soil, the blade will only peel off the soil layer, and the covering effect on the sugarcane head is not obvious, which is not conducive to the subsequent germination of the sugarcane. If the "crater" terrain with a concave middle and convex sides is encountered, the disadvantage is more obvious.

[0005] 2. The feeding baffle uses a roughly vertical serrated edge. When the sugarcane is transported inward, it is not aligned with the height of the channel. The feeding roller at the front end of the channel lifts the sugarcane to the appropriate position and then sucks it in. Since the rubber plate on the feeding roller does not necessarily exert force inward on the sugarcane at low and high positions, it may also push the sugarcane outward. The feeding baffle needs to be repeatedly moved and transported until the sugarcane is lifted into the channel. This is a disordered process. The sugarcane at the upper and lower ends of the channel may take a certain amount of time to enter, resulting in convergence and overlap with the sugarcane that enters smoothly in the middle at some point. If this technology is applied to a whole-stalk sugarcane harvester, it may cause blockage.

[0006] 3. The square steel blades currently used are often not wear-resistant, and the wear and tear of cutting in the soil is large. After wear and tear, the cutting effect will be greatly reduced, resulting in an increase in the rate of sugarcane head breakage (the probability of sugarcane head splitting). Although non-soil cutting can reduce wear and tear, it will greatly increase the rate of sugarcane head breakage, causing losses to farmers.

[0007] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0009] To achieve the above-mentioned purpose, the utility model provides a sugarcane cutting system with a soil covering function, comprising: a mounting frame connected to a sugarcane harvester; at least two output shafts, which are parallel to each other and arranged on the mounting frame in a vertical direction, and are connected to a driving mechanism, and the output shafts are driven to rotate by the driving mechanism; a knife disc, which is arranged at the lower end of the output shaft in a one-to-one correspondence, and is arranged close to each other, and there is a gap space, a plurality of blades are evenly arranged on the lower surface of the knife disc, and the front ends of the plurality of blades extend outward from the edge of the knife disc, and the blades on the two knife discs close to each other are arranged staggered with each other; a plurality of soil covering plates are arranged on the lower surface of the knife disc, and the plurality of soil covering plates are evenly distributed radially along the radial direction of the knife disc; and a rubber plate, a plurality of rubber plates are evenly distributed in the vertical direction of each of the output shafts, the rubber plates are located above the knife disc, the outer edge of each rubber plate is arranged as a toothed curve, and the middle part is recessed inward, the rubber plates on the two adjacent output shafts are relatively close to each other, and the recessed part in the middle forms a sugarcane accommodating channel.

[0010] Preferably, in the above technical solution, the plate body of the covering plate is a trapezoidal structure, and the height of the plate body of the covering plate gradually decreases from the center to the edge of the cutter disc, and the outer edge of the covering plate does not exceed the outer circumference of the blades staggeredly arranged opposite to the cutter disc.

[0011] Preferably, in the above technical solution, the lower end of the rubber plate is arranged in contact with the upper surface of the knife disc, and the edge of the rubber plate is flush with the edge of the knife disc.

[0012] Preferably, in the above technical solution, the upper and lower sections of the outer edge of the rubber plate are vertical teeth, and the middle section is concave arc teeth.

[0013] Preferably, in the above technical solution, the sugarcane containing channel is small at the top and bottom and wide in the middle.

[0014] Preferably, in the above technical solution, the blade is in a centrally symmetrical petal shape.

[0015] Preferably, in the above technical solution, blades are provided at both ends of the blade, the blades are arc-shaped and are respectively located on both sides of the blade, and the blade back on each side is a straight line.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] (1) The utility model provides a sugarcane cutting system with a soil covering function, wherein a rubber plate is provided above the cutter disc and a soil covering plate is provided on the lower surface. When harvesting sugarcane, the lower part of the rubber plate and the soil covering plate at the bottom of the cutter disc respectively continuously bring the soil peeled off from the soil layer above and below the cutter disc to the middle and cover the position of the sugarcane head, thereby realizing the soil covering function which is beneficial to the germination of the sugarcane next year.

[0020] (2) In the sugarcane cutting system of the utility model, when the blade discs on both sides rotate, the rubber plates rotate accordingly, and a sugarcane receiving channel is formed in the middle of the rubber plates on both sides. After the sugarcane is crushed and the roots are cut, the lower end is sucked into the middle of the rubber plates as the rubber plates rotate and the sugarcane harvester moves forward. Since the upper surface edge of the blade disc has a chamfer, it is easier for the lower end of the sugarcane to move onto the blade disc. When the lower end of the sugarcane is sucked into the range of the sugarcane receiving channel, since the sugarcane is tilted and tilted downward at this time, the shape of the rubber plates can make the sugarcane receive an upward force when it is in a low position, and a downward force when it is in a high position, and finally the sugarcane is constrained near the middle position of the cavity, which is conducive to the sugarcane entering the impurity removal channel.

[0021] (3) The sugarcane cutting system of the utility model has a blade in the shape of a petal with central symmetry, and blades are provided at both ends of the blade, and the blades are arc-shaped. The arc-shaped blades make the cut of the sugarcane smooth and flat, reducing the probability of the sugarcane head splitting, and when the blade is worn, it has better cutting ability than the worn square blade, thereby increasing the service life.

When cutting, the driving mechanism 5 drives the output shaft 2 to rotate, and the output shaft 2 drives the knife disc 3 at the lower end to rotate to cut the sugarcane.

[0030] The specific structure is as follows: the mounting frame 1 is connected to the sugarcane harvester.

The output shaft is driven to rotate by the driving mechanism 5. A cutter disc 3 is installed at the lower end of each output shaft 2. The cutter discs below the output shaft 2 are arranged close to each other, and the interval between the edges of the two cutter discs 3 is about 10 mm. A plurality of blades 6 are installed on the lower surface of the cutter disc 3. In this embodiment, four blades 6 are arranged on the lower surface of each cutter disc 3, and the four blades are evenly distributed on the lower surface of the cutter disc. The front end of the blade 6 extends outward from the edge of the cutter disc 3, and the blades 6 on the two cutter discs 3 close to each other are arranged alternately. The blade 6 extends out of the cutter disc 3. When the cutter disc 3 rotates, the blade 6 rotates with it to cut the sugarcane. A plurality of soil covering plates 7 are provided on the lower surface of the cutter disc 3. In this embodiment, there are four soil covering plates 7. The four soil covering plates 7 are evenly distributed radially along the radial direction of the cutter disc 3. A plurality of rubber plates 4 are provided above the cutter disc 3.

The rubber plates 4 on two adjacent output shafts 2 are relatively close to each other, and the concave part in the middle forms a sugarcane holding channel 41. Rubber plates 4 are provided above the cutter disc 3 and soil covering plates 7 are provided on the lower surface. When harvesting sugarcane, the lower part of the rubber plate 4 and the soil covering sheet at the bottom of the cutter disc 3 continuously bring the soil peeled off from the soil layer above and below the cutter disc 3 to the middle, and cover the position of the sugarcane head, thereby realizing the soil covering function that is conducive to the germination of sugarcane next year.

[0031] The utility model provides a sugarcane cutting system with a soil covering function. When the cutter discs 3 on both sides rotate, the rubber plates 4 rotate accordingly. The sugarcane receiving passage 41 is formed in the middle of the rubber plates 4 on both sides. After the sugarcane is crushed and the root is cut, the lower end is sucked into the middle of the rubber plates 4 as the rubber plates 4 rotate and the sugarcane harvester moves forward. When the lower end of the sugarcane is sucked into the range of the sugarcane receiving passage 41, since the sugarcane is tilted and tilted downward at this time, the shape of the rubber plates 4 can make the sugarcane receive an upward force when it is in a low position, and receive a downward force when it is in a high position, and finally the sugarcane is constrained near the middle position of the cavity, so as to facilitate the sugarcane to enter the impurity removal passage.

The rubber plates 4 on two adjacent output shafts 2 are relatively close to each other, and the middle concave portion forms a sugarcane receiving channel 41. The sugarcane receiving channel 41 is small at the top and bottom and wide in the middle, which constrains the sugarcane near the middle position of the cavity, thereby facilitating the sugarcane to enter the impurity removal channel.

[0035] Preferably, the blade 6 is in a centrally symmetrical petal shape. Blades are provided at both ends of the blade 6, and the blades 6 are arc-shaped and located on both sides of the blade, respectively, and the blade backs on each side are straight lines. The arc-shaped blades make the cuts of the sugarcane smooth and smooth, reducing the probability of the sugarcane head splitting, and when the blades are worn, they have better cutting ability than worn square blades, thereby increasing the service life.

[0036] Preferably, the upper edge of the cutter disc 3 is chamfered 31. Since the upper surface edge of the cutter disc 3 has a chamfer 31, the lower end of the sugarcane can be moved onto the cutter disc 3 more easily.
