Description

Technical Field

[0001] The invention belongs to the technical field of wild rice stem harvesting equipment, and in particular relates to a wild rice stem harvester with a cutting blade that can adjust the level of the cutting blade. Background Art

[0002] In the prior art water chestnut harvester, the angle of the cutting knife of the cutting mechanism cannot be adjusted. For example, when the cutting knife is raised or lowered, it is easy to cause the cutting knife to form a certain angle with the horizontal plane, resulting in an oblique cut on the water chestnut when cutting the water chestnut. This cutting method is not easy to operate the water chestnut. Summary of the invention

[0003] The invention provides a water chestnut harvester with a cutting blade that can automatically adjust the level, aiming to solve the problem in the prior art that the water chestnut harvester's cutting blade cannot automatically adjust the level, causing the water chestnut to be easily damaged during harvesting.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A wild rice stem harvester with a cutting blade that can adjust the level of the cutting blade, comprising a frame, a cutting assembly for cutting wild rice stems arranged on the frame, a cutter arranged on the cutting assembly, two cutters, and a cutting channel formed between the two cutters;

[0006] The frame is provided with a walking mechanism, and there are two walking mechanisms, which are respectively arranged on both sides of the frame in the width direction. The cutting assembly includes a knife disc and an angle adjustment assembly that keeps the knife disc in a horizontal state during the cutting process.

[0007] A further improved solution: the walking mechanism is a crawler-type walking mechanism.

[0008] Based on the above technical solution: the crawler-type walking mechanism has a larger contact area with the ground. A larger contact area means that the walking mechanism has stronger stability on uneven or inclined ground and is less likely to roll over or slide. The crawler can evenly distribute the weight of the machine body to the ground, thereby reducing the pressure on the ground and avoiding excessive damage to the soil or ground structure. The pattern and texture design on the crawler can increase the friction with the ground, so that the walking mechanism can maintain good grip even on wet or muddy ground.

[0009] A further improved solution: the cutter is located right in front of the frame.

[0010] Based on the above technical solution: the cutter is located in front of the frame. Since the cutter is located before the walking mechanism, it can make the walking mechanism walk between two rows of water chestnuts, thereby avoiding the risk of the walking mechanism directly crushing the water chestnuts.

[0011] A further improved solution: the cutting assembly is rotatably connected to the frame via a rotating shaft, and the frame is also provided with a hydraulic cylinder for driving the cutting assembly to swing around the rotating shaft, and the hydraulic cylinder adjusts the cutting height of the cutter by adjusting the angle of the cutting assembly.

[0012] Based on the above technical solution: The growth height of wild rice may vary depending on factors such as variety, growth environment, and growth cycle. At the same time, the sinking height of the whole machine will vary depending on the soil conditions of the wild rice field. By adjusting the angle of the cutting component, the height of the cutter can be precisely controlled to adapt to wild rice of different heights to ensure the accuracy and completeness of the harvest. A reasonable cutting height can reduce excessive damage to the stems of wild rice, avoid cutting too low to cause root damage or cutting too high to cause incomplete stem breakage. This helps maintain the quality and yield of wild rice. Cutting too low will cause the cutter to contact the soil and accelerate tool wear; cutting too high will damage the wild rice. A reasonable cutting height can effectively increase the service life of the cutter and reduce the damage rate of wild rice harvest.

[0013] A further improved solution: the cutting assembly includes a cutting frame rotatably connected to the rotating shaft, the cutter is rotatably connected to the cutting frame, the cutter disc is arranged on the cutter, the cutter discs on the two cutters form the cutting channel, the angle adjustment assembly is arranged between the cutting frame and the frame, and the angle adjustment assembly is an angle adjustment assembly that keeps the cutter disc in a horizontal state when the cutting assembly adjusts its angle.

[0014] Based on the above technical solution: Keeping the blade disc horizontal can ensure that the cut on the wild rice is flat and smooth when it is cut, reducing damage and quality degradation caused by uneven cuts. Flat cuts help reduce the loss of wild rice during the harvesting process, increase yield and economic benefits. For wild rice sold as a vegetable, a flat cut can also improve its appearance quality and increase market competitiveness. The angle adjustment component can automatically adjust the position of the blade disc when the cutting component adjusts the angle, so that it always remains horizontal. This helps ensure that the cutter can cut at the best angle under different terrains and crop heights.

[0015] A further improved solution: the angle adjustment assembly includes a transmission mechanism, and when the cutting assembly swings in the clockwise direction, the transmission mechanism drives the cutter to swing in the counterclockwise direction; when the cutting assembly swings in the counterclockwise direction, the transmission mechanism drives the cutter to swing in the clockwise direction, and the transmission mechanism makes the swing angle of the cutter equal to the swing angle of the cutting frame.

[0016] Based on the above technical solution: when the cutting assembly swings on the frame, the transmission mechanism can balance the torque generated by the swing of the cutting assembly by driving the cutter to swing in the opposite direction, thereby maintaining the stability of the entire cutting system. Since the cutter and the cutting frame swing in opposite directions, the relative movement between them can offset some of the vibrations, making the cutting process smoother. The design of the transmission mechanism makes the swing angle of the cutter equal to the swing angle of the cutting frame, which means that the operator can indirectly control the cutting position of the cutter by precisely controlling the swing angle of the cutting frame, thereby improving the cutting accuracy. During the cutting process, no matter how the cutting assembly swings, the transmission mechanism can ensure that the cutter remains horizontal, thereby ensuring that the cut on the wild rice is flat and smooth.

[0017] A further improved solution: the angle adjustment assembly includes an arc-shaped rack fixed on the frame, the axis of the arc-shaped rack is coaxial with the axis of the rotating shaft, the transmission mechanism includes a driving gear arranged on the cutting frame and meshing with the arc-shaped rack, the transmission mechanism also includes a driven gear arranged on the cutting frame and meshing with the driving gear, and the driven gear drives the cutter to swing.

[0018] Based on the above technical solution: Due to the close meshing of the arc-shaped rack and the driving gear, and the precise meshing relationship between the driven gear and the driving gear, the angle adjustment component can achieve precise angle adjustment. This ensures that the cutter can maintain a stable swing angle when swinging, thereby improving the cutting accuracy. The design of the transmission mechanism allows the swing of the cutter to be synchronized with the swing of the cutting frame. This means that when the cutting frame swings around the rotating shaft, the cutter will swing at the same angle and direction. This synchronous swing helps to maintain the stability and continuity of the cutting process. The design of the angle adjustment component enables it to adapt to the swing requirements of different angles and directions. No matter how the cutting component swings, the transmission mechanism can ensure that the cutter cuts at the correct angle. This adaptability makes the angle adjustment component have a wide range of application prospects in agricultural machinery. The structure of the angle adjustment component is relatively simple, mainly consisting of an arc-shaped rack, a driving gear and a driven gear. This simple structure reduces the manufacturing cost and maintenance difficulty, while improving the reliability and durability of the equipment.

[0019] A further improved solution: the arc-shaped rack is fixed to the frame via a connecting frame, one end of the connecting frame is fixed to the frame via bolts, and the other end of the connecting frame is welded to the arc-shaped rack.

[0020] Based on the above technical solution: Fixing one end of the connecting frame to the frame by bolts can ensure that the position of the connecting frame on the frame is stable and not prone to loosening or displacement. Connecting the other end of the connecting frame to the arc-shaped rack by welding can ensure the firmness of the arc-shaped rack on the connecting frame to avoid shaking or falling off during the transmission process. The connecting frame serves as a bridge between the arc-shaped rack and the frame, and the two are tightly connected together by bolts and welding to form an integral structure. This overall structure helps to enhance the integrity and rigidity of the equipment, and improve the equipment's anti-deformation ability and load-bearing capacity. By fixing the connecting frame, the rigidity of the arc-shaped rack can be further improved to ensure that it maintains a stable shape and position during the transmission process.

[0021] A further improved solution: a reinforcing rod for improving the strength of the connecting frame is provided between the arc-shaped rack and the connecting frame, one end of the reinforcing rod is welded to the arc-shaped rack, and the other end of the reinforcing rod is welded to the connecting frame.

[0022] Based on the above technical solution: one end of the reinforcing rod is welded to the arc-shaped rack, and the other end is welded to the connecting frame, forming a triangular stable structure. This design effectively disperses the stress and pressure on the connecting frame, thereby improving the strength of the connecting frame. The reinforcing rod not only improves the strength of the connecting frame, but also enhances the stability of the entire structure. During the transmission process, the meshing of the arc-shaped rack and the driving gear will generate certain forces and vibrations, which may be transmitted to the connecting frame. The setting of the reinforcing rod helps to reduce the impact of these forces and vibrations on the connecting frame, thereby maintaining the stability of the entire structure.

[0023] A further improved solution: the driving gear is rotatably connected to the cutting frame through a frame body, the frame body is fixed to the cutting frame through bolts, the driving gear is rotatably connected to the frame body through a shaft body, the cutter is rotatably connected to the cutting frame through a drive shaft, and the driven gear is installed on the drive shaft through a key connection.

[0024] Based on the above technical solution: the driving gear is rotatably connected to the frame through the shaft, and the frame is fixed to the cutting frame by bolts. This design allows the driving gear to rotate flexibly during the transmission process, reduces the energy loss caused by friction, and improves the transmission efficiency. The driven gear is installed on the drive shaft through a key connection to directly drive the cutter to rotate. This direct drive method reduces the intermediate links in the transmission chain, reduces energy loss, and further improves the transmission efficiency. The frame is fixed to the cutting frame by bolts. This connection method is not only easy to install, but also can ensure the stability of the frame during the transmission process. The stable structure helps to reduce vibration and noise and improve the overall performance of the equipment. The shaft and drive shaft respectively support the driving gear and the cutter firmly on the cutting frame. This design enhances the overall structural strength of the transmission system, enabling it to withstand greater loads and impacts.

[0025] The beneficial effects of the present invention are:

[0026] The present invention arranges the traveling mechanism on both sides of the frame width direction, so that when the machine is in operation, the traveling wheels can be located in the open space between two rows of wild rice stems and travel. This layout effectively avoids the traveling mechanism from directly contacting the wild rice stems, thereby reducing the risk of crushing the wild rice stems.

[0027] The design of the double-sided walking mechanism makes the machine more stable during walking, which is conducive to improving the operating speed. At the same time, the design of the middle cutting channel ensures the cutting efficiency. The combination of the two realizes efficient operation while also ensuring the protection of wild rice stems.

[0028] By setting an angle adjustment component, the angle adjustment component is used to keep the knife disc horizontal. Keeping the knife disc horizontal can ensure that the cut on the wild rice is flat and smooth when it is cut, reducing damage and quality degradation caused by uneven cuts. Flat cuts help reduce the loss of wild rice during the harvesting process, increase yield and economic benefits. For wild rice sold as a vegetable, a flat cut can also improve its appearance quality and increase market competitiveness. Keep horizontal: The angle adjustment component can automatically adjust the position of the knife disc when the cutting component adjusts the angle, so that it always remains horizontal. This helps ensure that the cutter can cut at the best angle under different terrains and crop heights.

[0029] By optimizing the layout of the walking mechanism and the cutting channel, the present invention significantly reduces the damage rate of the machine to the wild rice stems. This not only improves the quality of the wild rice stems, but also reduces the economic losses of farmers. In practical applications, the wild rice stem harvester designed in this way can more flexibly adapt to different field environments, especially when the wild rice stem planting density is high and the row spacing is narrow, it can still maintain a high operating efficiency and a low damage rate.
