Description

Technical Field

[0001] The present invention belongs to the technical field of water bamboo harvesting equipment, and particularly relates to a compact water bamboo harvester with cutting alignment. Background Art

[0002] The existing water bamboo harvesters include a vehicle frame, a harvesting assembly arranged on the vehicle frame, and a cab arranged on the vehicle frame. A driving machine is arranged on the vehicle frame to drive the water bamboo harvester to move. Using a water bamboo harvester to harvest water bamboo greatly improves the harvesting efficiency of water bamboo.

[0003] However, in the existing water bamboo harvesters, the cutter head of the cutting mechanism is usually arranged on one side of the machine frame to maintain the stability of the machine frame. However, when harvesting water bamboo with this structure of water bamboo harvester, the walking mechanism will crush the water bamboo, causing damage to the water bamboo. Summary of the Invention

[0004] The present invention provides a compact water bamboo harvester with cutting alignment, aiming to solve the problem that the existing water bamboo harvesters are prone to damage the water bamboo.

[0005] To solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] A compact water bamboo harvester with cutting alignment includes a chassis, a harvesting assembly is arranged on the chassis, and a cab is also arranged on the chassis;

[0007] The harvesting assembly includes a conveyor for conveying the harvested water bamboo and a cutter for cutting the water bamboo; the conveyor includes a horizontal conveyor and an inclined conveyor. The cutter is arranged at the lower end of the inclined conveyor. The inclined conveyor conveys the water bamboo cut by the cutter into the horizontal conveyor. And the output end of the inclined conveyor is located behind and above the input end of the horizontal conveyor. The cutter is located in the middle of the chassis in the width direction;

[0008] The horizontal conveyor is located on one side of the cab. A driving machine for driving the chassis to move is arranged on the chassis directly behind the cab. The driving machine drives the conveyor through a chain transmission mechanism;

[0009] The driving machine includes an output shaft. The chain transmission mechanism includes a driving sprocket installed on the output shaft. The conveyor includes a power input shaft, and a driven sprocket is arranged on the power input shaft. A transmission chain for transmitting power is arranged between the driving sprocket and the driven sprocket. A tensioning sprocket for preventing the transmission chain from loosening is also arranged on the chassis.

[0010] Further improved solution: The inclined conveyor includes a low end where the cutter is installed and a high end opposite to the low end, and the low end extends to the front of the chassis.

[0011] Based on the above technical solution: The inclined conveyor includes a low end and a high end. The cutter is installed at the low end and extends to the front of the chassis, and is located in the middle of the chassis in the width direction. This design enables the cutter to directly and accurately contact and cut the water bamboo, while avoiding interference with other parts of the chassis. The low end serves as the installation position of the cutter, and its extended design helps to ensure that the cutter can work stably and efficiently during operation. The high end is connected to the subsequent processing or storage mechanism to form a complete harvesting process. The cutter works at the low end of the inclined conveyor and can quickly and accurately cut the water bamboo. Since the low end is located in the middle of the chassis in the width direction, the cutter can cover a wider cutting range and improve the harvesting efficiency. During the cutting process, the traveling mechanism is located behind or on the side of the cutter, so it will not directly contact the cut water bamboo. This design effectively avoids the situation of the traveling mechanism crushing the water bamboo during operation and protects the integrity of the water bamboo.

[0012] Further improved solution: The horizontal conveyor is a first clamping conveyor, which includes a first rotary conveyor arm and a second rotary conveyor arm. A conveying channel is formed between the first rotary conveyor arm and the second rotary conveyor arm. The first clamping conveyor further includes a first bracket. The first rotary conveyor arm and the second rotary conveyor arm are both rotatably connected to the first bracket. Pushing teeth are provided on both the first rotary conveyor arm and the second rotary conveyor arm, and a conveying groove for accommodating the water bamboo is formed between two adjacent pushing teeth.

[0013] Based on the above technical solution: The conveying channel formed between the first rotary conveyor arm and the second rotary conveyor arm provides a stable conveying path for the water bamboo. The design of the pushing teeth enables the water bamboo to be effectively clamped and conveyed, reducing the jamming and stagnation phenomena during the conveying process. The rotary conveyor arms are rotatably connected to the first bracket, ensuring the stability and reliability of the conveying. The design of the conveying groove enables the water bamboo to maintain a certain spacing and arrangement during the conveying process, avoiding mutual extrusion and damage. The pushing teeth are made of soft or elastic materials, which can reduce the scratches and abrasions on the surface of the water bamboo. The stable conveying speed and uniform clamping force help to maintain the integrity and freshness of the water bamboo. The direct contact with the conveyor during the conveying process is reduced, lowering the heat and wear generated by friction, thereby maintaining the quality of the water bamboo. The first clamping conveyor can adapt to water bamboos of different sizes and shapes. By adjusting the spacing of the pushing teeth and the size of the conveying groove, the conveying requirements of different varieties can be met.

[0014] Further improved solution: A first driving wheel for driving the first rotary conveying arm is further provided on the first support. A first driven wheel is also provided on the first support. The first driven wheel is rotatably connected to the first support. The first rotary conveying arm is disposed between the first driving wheel and the first driven wheel. The power input shaft is rotatably connected to the first support. The power input shaft drives the first driving wheel and the second rotary conveying arm to rotate through a gear reversing assembly.

[0015] Based on the above technical solution: The power input shaft drives the first driving wheel through a gear reversing assembly, which makes the power transmission more direct and efficient. The gear reversing assembly can also achieve power reversing to meet the requirements of different conveying directions. The first driving wheel drives the second rotary conveying arm to rotate through a gear transmission assembly, ensuring that the two rotary conveying arms can work synchronously and stably. The gear transmission has the advantages of compact structure, reliable transmission of motion, and constant instantaneous transmission ratio, making the conveying process smoother and more efficient. The designs of the gear reversing assembly and the gear transmission assembly make the driving system of the conveyor more flexible. By adjusting the number of teeth and transmission ratio of the gears, the conveying speed and direction of the conveyor can be easily changed to adapt to different operation requirements. The conveying channel formed between the first rotary conveying arm and the second rotary conveying arm can stably convey water bamboo shoots under the drive of the driving machine. The design of the conveying groove enables the water bamboo shoots to maintain a certain spacing and arrangement during the conveying process, avoiding mutual extrusion and damage. The arrangement of the feeding teeth enables the conveyor to effectively clamp the water bamboo shoots, preventing them from slipping or rolling during the conveying process. At the same time, the soft or elastic material of the feeding teeth can also reduce scratches and wear on the surface of the water bamboo shoots.

[0016] Further improved solution: A second driving wheel and a second driven wheel are further provided on the first support. Both the second driving wheel and the second driven wheel are rotatably connected to the first support. The second rotary conveying arm is disposed between the second driving wheel and the second driven wheel.

[0017] Based on the above technical solution: By integrating the second driving wheel and the second driven wheel on the first support, the structure of the entire conveyor is more compact, occupying less space and facilitating deployment in a limited working environment. The setting of the second rotary conveying arm makes the weight distribution of the conveyor more uniform, reducing vibrations and noises caused by imbalance and improving the overall running smoothness. Driven by the gear transmission mechanism, the first rotary conveying arm and the second rotary conveying arm can stably convey water bamboo shoots at a constant speed, reducing the problem of unstable conveying caused by speed fluctuations. The gear transmission mechanism has the characteristics of simple structure and reliable transmission. Compared with other transmission methods, its failure rate is lower and the maintenance cost is correspondingly reduced.

[0018] Further improved solution: The gear commutation assembly includes a commutation shaft rotatably connected to the first bracket, the power input shaft drives the commutation shaft, a driving commutation gear is arranged on the commutation shaft, driven commutation gears meshing with the driving commutation gear are arranged on both the first driving wheel and the second driving wheel, the driving commutation gear and the driven commutation gears are all bevel gears, and the driven commutation gears are respectively installed on the first driving wheel and the second driving wheel through transmission shafts.

[0019] Based on the above technical solution: Both the driving commutation gear and the driven commutation gears adopt bevel gear designs. Bevel gear transmission has advantages such as a compact structure, a stable transmission ratio, and a strong load-bearing capacity, which can ensure the efficient transmission of power during the commutation process. The meshing characteristics of bevel gears make the commutation process smooth and without impact, reducing the vibration and noise generated during commutation and improving the overall operating stability of the conveyor. The vertical meshing method of bevel gears makes the commutation assembly more compact in structure, effectively utilizing the space on the first bracket and providing convenience for the arrangement of other components. The transmission method of bevel gears is relatively simple and has a low maintenance cost. At the same time, since the commutation assembly is integrated on the first bracket, maintenance is more convenient. The transmission ratio of bevel gears is constant and is not affected by changes in load during the transmission process, thus ensuring the stable operation of the conveyor after commutation. Bevel gears have a high load-bearing capacity, can adapt to the conveying requirements of larger loads, and improve the overall performance of the conveyor.

[0020] Further improved solution: The inclined conveyor is a second clamping conveyor, the second clamping conveyor includes a second bracket arranged on the first bracket, a third rotary conveyor arm and a fourth rotary conveyor arm are arranged on the second bracket, an inclined conveying channel is formed between the third rotary conveyor arm and the fourth rotary conveyor arm, and feeding teeth are arranged on both the third rotary conveyor arm and the fourth rotary conveyor arm, and a conveying groove for accommodating water bamboo is formed between two adjacent feeding teeth.

[0021] Based on the above technical solution: The design of the inclined conveying channel enables the conveyor to realize the inclined conveying of materials in a limited space, which is particularly suitable for working environments with limited space. The arrangement of the feeding teeth ensures that the water bamboo can be stably clamped during the conveying process, avoiding damage caused by slipping or rolling. The feeding teeth are made of soft or elastic materials, which can reduce scratches and wear on the surface of the water bamboo and maintain the integrity and freshness of the water bamboo. The angle of the inclined conveying channel can be adjusted according to actual needs to adapt to the conveying requirements of different inclined angles.

[0022] Further improved solution: A third driving wheel and a third driven wheel are arranged on the second support. Both the third driving wheel and the third driven wheel are rotatably connected to the second support. The third rotary conveyor arm is arranged on the third driving wheel and the third driven wheel. A fourth driving wheel and a fourth driven wheel are further arranged on the second support. The fourth rotary conveyor arm is arranged on the fourth driving wheel and the fourth driven wheel. Both the fourth driving wheel and the fourth driven wheel are rotatably connected to the second support. The first driven wheel drives the third driving wheel through a first universal coupling, and the second driven wheel drives the fourth driving wheel through a second universal coupling.

[0023] Based on the above technical solution: The gear drive has the advantages of high transmission efficiency, compact structure, reliable operation, etc. Driving the fourth driving wheel through the gear drive can ensure the accuracy and efficiency of power transmission. The universal coupling can transmit rotational motion and allows a large angular deviation between the two shafts. Connecting the first driven wheel and the third driving wheel through the universal coupling can adapt to different installation angles between them and ensure the smooth transmission of power. Multiple driving wheels and driven wheels, as well as corresponding transmission mechanisms, are integrated on the second support, making the structure of the entire conveyor more compact. This design not only saves space but also improves the overall stability and reliability of the conveyor. By reasonably arranging each component, the maintenance and repair of the conveyor are made more convenient. For example, it is convenient to check the wear conditions of the gear drive and the universal coupling and perform necessary replacements or repairs.

[0024] Further improved solution: A traveling mechanism is further arranged on the chassis. The traveling mechanism includes crawler belts. There are two crawler belts, and the two crawler belts are respectively located on both sides of the chassis. The crawler belts are driven by a driving machine. A main driving wheel and a driven wheel are further arranged on the chassis. Both the main driving wheel and the driven wheel are rotatably connected to the chassis. The driving machine drives the main driving wheel. The crawler belts are arranged on the main driving wheel and the driven wheel. A first intermediate wheel, a second intermediate wheel, a third intermediate wheel, a fourth intermediate wheel, and a fifth intermediate wheel are further arranged on the chassis. The first intermediate wheel, the second intermediate wheel, the third intermediate wheel, the fourth intermediate wheel, and the fifth intermediate wheel are all rotatably connected to the chassis. Moreover, the first intermediate wheel, the second intermediate wheel, the third intermediate wheel, the fourth intermediate wheel, and the fifth intermediate wheel all keep the crawler belts in contact with the ground. The first intermediate wheel and the second intermediate wheel are arranged at one end of the chassis close to the driven wheel, and the third intermediate wheel, the fourth intermediate wheel, and the fifth intermediate wheel are arranged at one end of the chassis close to the main driving wheel.

[0025] Based on the above technical solution: The two crawlers are respectively located on both sides of the chassis, providing a good ground contact area and grip, ensuring the stable movement of the equipment on various terrains. The five idlers are all rotatably connected to the chassis and keep the crawlers in contact with the ground. This design not only increases the support points of the crawlers but also improves the tension and stability of the crawlers, further enhancing the stability of the running gear. The main drive wheel is directly driven by the drive motor. This design ensures that the crawlers can rotate smoothly and continuously, thus providing stable driving force. The first idler and the second idler are arranged at one end of the chassis close to the slave drive wheel, while the third idler, the fourth idler, and the fifth idler are arranged at one end of the chassis close to the main drive wheel. This layout enables the crawlers to maintain uniform tension during rotation, reducing the problem of unstable driving caused by loose crawlers. The double-crawler design and the supporting effect of the idlers enable the running gear to adapt to various complex terrains, such as muddy, rough, and sloping terrains. This adaptability is particularly important for application scenarios such as agricultural harvesting and material handling. The design of the running gear is relatively simple, and the connection and cooperation between various components are tight and reliable. This makes the equipment more convenient for maintenance and repair, reducing the maintenance cost and time.

[0026] Further improved solution: The cab includes a driver's seat and a control console arranged in front of the driver's seat. The driver's seat is located between the drive motor and the control console. The driver's seat includes a seat cushion and a backrest. The backrest is arranged on the seat cushion. The seat cushion is fixed to the chassis by bolts. An armrest is also arranged on the seat cushion. The armrests are arranged on both sides of the seat cushion, and one end of each armrest contacts the backrest. The control console includes a control box. A travel control handle for controlling the running gear is arranged on the control box. A cutting control handle for controlling the cutter is also arranged on the control box. A conveyor control handle for controlling the conveyor is also arranged on the control box.

[0027] Based on the above technical solution: The console is arranged in front of the driver's seat, enabling the operator to conveniently operate and monitor various equipment functions. The walking control handle, cutting control handle, and conveyor control handle are all located on the control box, and their layout is reasonable, allowing the operator to easily reach and accurately control them. The walking control handle, cutting control handle, and conveyor control handle are set on the console, which are respectively used to control the operations of the walking mechanism, cutter, and conveyor. This design enables the operator to achieve comprehensive control of the entire equipment through a single console, improving the operation efficiency. The driver's seat includes a seat cushion and a backrest, providing the operator with comfortable sitting support. The seat cushion is fixed to the chassis by bolts, ensuring the stability and safety of the driver's seat. At the same time, armrests are also set on the seat cushion, providing the operator with additional support and comfort. The backrest is set on the seat cushion, providing the operator with back support. The setting of the armrests further enhances the operator's comfort, especially during long-term operation, which can effectively relieve the fatigue of the arms and shoulders. The driver's seat is firmly fixed to the chassis by bolts, ensuring the stability and safety of the operator during the operation of the equipment. Even when driving on bumpy or uneven terrain, the driver's seat can remain stable, providing reliable protection for the operator.

[0028] The beneficial effects of the present invention are as follows:

[0029] By reasonably arranging key components such as the harvesting assembly, conveyor, and drive machine, the present invention effectively reduces the overall center of gravity of the harvester. The low center of gravity design makes the machine more stable during operation, reducing the risk of rollover caused by unstable center of gravity. The conveyor is divided into a horizontal conveyor and an inclined conveyor, and the two work together to achieve efficient and stable conveyance of water bamboo. The inclined conveyor smoothly conveys the water bamboo cut by the cutter into the horizontal conveyor, avoiding problems such as blockage or scattering caused by unsmooth conveyance.

[0030] The horizontal conveyor is located on one side of the cab. This layout makes the water bamboo harvester more compact in structure and can adapt to more working environments. At the same time, the cutter is set in the middle of the chassis width direction, enabling the walking mechanism to walk on the open space between two rows of water bamboo during operation. This layout effectively avoids the direct contact between the walking mechanism and the water bamboo plants, thereby reducing the risk of crushing the water bamboo.

[0031] The drive machine drives the conveyor to work through a chain drive mechanism. This transmission method has the advantages of simple structure, high transmission efficiency, and convenient maintenance. At the same time, the chain drive mechanism also has a certain buffering and shock absorption effect, which helps to reduce the vibration and impact of the machine during operation. In order to prevent the drive chain from loosening and affecting the transmission efficiency or even causing failures, a tensioning sprocket is also provided on the chassis. The tensioning sprocket can adjust the tension of the drive chain according to the actual situation to ensure that it is always in the best working state. This design effectively extends the service life of the drive chain and improves the reliability of the whole machine. Brief Description of the Drawings

[0059] The working principle of this embodiment:

[0060] The cutter 3 is arranged at the lower end of the inclined conveyor 5. When the machine enters the water bamboo field for operation, the cutter 3 starts to work and cuts off the mature water bamboo. Under the action of the conveyor after cutting, the water bamboo moves upward along the inclined conveyor 5 until it enters the horizontal conveyor 4. The inclined conveyor 5 and the horizontal conveyor 4 together constitute the conveying system of the water bamboo. The inclined conveyor 5 is responsible for conveying the cut water bamboo from a lower place to a higher place, while the horizontal conveyor 4 is responsible for further conveying the water bamboo to the collection area or subsequent processing equipment.

[0061] The power of the conveyor comes from the drive motor 6, and the power is transmitted to the power input shaft of the conveyor through the chain drive mechanism. The drive motor 6 is installed directly behind the cab 2 on the chassis 1 and provides power for the entire harvester. The output shaft of the drive motor 6 is connected to the power input shaft of the conveyor through the chain drive mechanism to achieve power transmission. The traveling mechanism of the harvester usually includes components such as crawler belts 14 or tires, and can travel stably on different terrains. The power of the traveling mechanism also comes from the drive motor 6, and the power is transmitted to the traveling wheels or crawler belts 14 through the transmission system.
