Description

Technical Field

[0001] This invention relates to the field of crop harvesting technology, specifically a combine harvester for the directional separation and conveying of dried moss leaves. Background Technology

[0002] Stem lettuce (also known as stem lettuce) is a widely cultivated vegetable in my country. Because stem lettuce grows upright in the field when mature, and its edible part is mainly the fleshy tender stem, harvesting it requires multiple processes, including cutting off the roots, peeling off the large outer leaves, washing, grading, and packing.

[0003] Currently, the harvesting of dried moss in my country still relies heavily on manual labor, making it a typical labor-intensive operation. Manual harvesting is not only inefficient and extremely labor-intensive, but also, due to the shortage and soaring costs of rural labor in recent years, it has severely restricted the large-scale cultivation and industrial development of the dried moss industry.

[0004] Although some machinery has emerged on the market that attempts to harvest root vegetables, the following technical bottlenecks are generally encountered when dealing with moss, a crop with unique physical characteristics: Inclined conveying systems are prone to slippage and have poor self-adaptive clamping capabilities. Due to individual differences in the growth of moss stems, their thickness varies, and their epidermis is quite delicate. Existing clamping and conveying devices mostly use fixed flat belts or chains. When conveying upwards on a slope, if the clamping force is too small, the moss stems of varying thicknesses are very easy to slip down and tip over under the influence of gravity, causing blockages. If the clamping force is too large, the commercial value of the moss stems is easily crushed or scratched.

[0005] Leaf separation is difficult and they are prone to tangling and clogging: The outer leaves of the moss stem are abundant and flexible. Existing leaf removal machines mostly use rotary cutters or rigid roller brushes. This method not only easily damages the tender stems of the moss stem, but also the highly flexible waste leaves are very easy to get tangled on the drive shaft and pulley, causing the machine to frequently jam and slip, making it impossible to achieve long-term continuous operation. Summary of the Invention

[0006] To address the problems in the existing technology, the present invention provides a combine harvester for the directional separation and conveying of dried moss leaves. The technical solution adopted by this invention to solve its technical problem is: a moss leaf directional separation and conveying combine harvester, including a cab, a transport component and a storage bin located on one side of the cab, and a harvesting component located on the front side of the cab and connected by a steel frame. The harvesting component includes: The drive frame is fixed on the steel frame, and the drive frame is equipped with a leaf removal mechanism and a cutting blade located below the leaf removal mechanism; Two sets of conveyor belts are symmetrically and obliquely positioned above the cutting blade in an inverted "V" shape. Both sets of conveyor belts extend upwards towards the side closest to the cab, serving to lift and transport the moss. The crossbars are positioned below the two sets of conveyor belts and are arranged side by side at the bottom of the two sets of conveyor belts. When the two sets of conveyor belts move inward, they can simultaneously trigger the lifting assembly set inside the crossbar to push upward, so as to apply an upward holding force to the moss above the crossbar.

[0007] The beneficial effects of this invention are: (1) The moss leaf directional separation and conveying combine harvester of the present invention cleverly transforms the lateral widening displacement of the belt into a longitudinal supporting force at the bottom. When encountering a thinner moss leaf and the belt moves inward and clamps, the lower extension column magnetically attracts and squeezes the trigger rod, and through the internal inclined wedge mechanism, forces the pushing column above the crossbar to pop up. This adaptive lifting design provides an upward step support force to the bottom of the moss leaf without adding any additional electric motor, and prevents the moss leaf from sliding down and tipping over during the inclined conveying process.

[0008] (2) The moss leaf directional separation and conveying combine harvester of the present invention adopts a spatial linkage mechanism for the leaf removal mechanism, which converts the rotational motion of the drive motor into a high-frequency reciprocating linear scouring motion along the direction of the inclined guide rod. Combined with a leaf removal cover made of highly elastic material with an adjustable opening size, it can flexibly deform to conform to the contours of moss stems of different thicknesses during high-speed leaf removal. This ensures that the large outer leaves are removed cleanly in pieces, while also providing excellent buffer protection for the delicate epidermis of the moss stems, avoiding mechanical damage.

Detailed Implementation

[0012] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0013] like Figure 1 - Figure 8 As shown, a moss leaf directional separation and conveying combine harvester of the present invention includes a cab 100, a transport component 300 and a collection bin 400 located on one side of the cab 100, and a harvesting component 200 located on the front side of the cab 100 and connected by a steel frame 210. The harvesting component 200 includes: The drive frame 250 is fixed on the steel frame 210. The drive frame 250 is equipped with a leaf removal mechanism and a cutting blade 500 located below the leaf removal mechanism. Two sets of conveyor belts 240 are symmetrically and obliquely arranged above the cutter 500 in an inverted "V" shape. The two sets of conveyor belts 240 extend upwards towards the side closest to the cab 100, for lifting and transporting the moss. A crossbar 600 is set below the two sets of conveyor belts 240 and is set side by side at the bottom of the two sets of conveyor belts 240. When the two sets of conveyor belts 240 move inward, they can simultaneously trigger the lifting assembly set inside the crossbar 600 to push upward, so as to apply an upward holding force to the moss above the crossbar 600.

[0014] The harvesting unit 200, located in front of the cab 100, enters the moss planting area. The bottom cutting blade 500 cuts the base of the moss, while simultaneously, two sets of conveyor belts 240 above the cutting blade 500, using their inverted "V"-shaped structure, clamp and lift the cut moss from both sides. Because the belts are tilted upwards towards the cab, the moss is synchronously conveyed backwards and upwards. When the moss changes in size or density during transport, causing the two sets of conveyor belts 240 to move inwards for a tighter clamping, this movement is converted into mechanical thrust, synchronously triggering the lifting assembly inside the crossbar 600 to push upwards. The pushing column acts directly on the bottom of the moss, providing an upward auxiliary supporting force.

[0015] Cutting and lifting / conveying are carried out simultaneously. The inverted "V" shaped belt design conforms to the shape characteristics of moss that is thinner at the bottom and thicker at the top, ensuring stable clamping. It is the first to have a linkage structure that reduces the clamping gap and supports the bottom. When encountering thinner or concentrated moss, the belt clamps inward while automatically triggering the bottom to support upward, effectively preventing the moss from sliding down due to gravity during inclined conveying, thus ensuring the continuity and stability of the transmission.

[0016] When harvesting mature moss in the field, the harvester moves at a speed of 5 km / h. The front-mounted harvesting unit 200 is aligned with the moss ridge. The cutting blade 500 cuts the moss root, and the inverted "V"-shaped conveyor belt 240 immediately clamps the moss stem and transports it up the slope. When encountering an area with dense planting and thinner moss stems, the two side belts move inward to ensure a tight clamp. At this time, the lifting component inside the crossbar 600 is triggered and automatically springs up, supporting the bottom of the moss from below to prevent it from slipping down the slope. The moss is then smoothly transported to the rear transport unit 300.

[0017] As a preferred technical solution, the leaf removal mechanism includes a drive motor 251, a bevel gear set 252, and two sets of transmission boxes 253 respectively symmetrically arranged on both sides of the drive frame 250. The output end of the drive motor 251 is connected to the input end of the bevel gear set 252. The two output ends of the bevel gear set 252 are respectively connected to the input ends of the two transmission boxes 253. The output ends of the two transmission boxes 253 are respectively connected to and drive the two rotating disks 254 to rotate. The guide rod 256 is inclined and its height is always higher than the uppermost movement trajectory of the rotating disk 254. The sliding sleeve 257 is slidably sleeved on the guide rod 256. A connecting rod 255 is provided between the rotating disk 254 and the sliding sleeve 257. A blade remover cover 260 is fixedly installed on one side of the sliding sleeve 257, and moves up and down as the sliding sleeve 257 slides back and forth on the guide rod 256.

[0018] The drive motor 251 starts, and its output torque is split into two through the bevel gear set 252, transmitting the power to the transmission boxes 253 on both sides of the drive frame 250. The transmission boxes 253 drive their corresponding rotating disks 254 to perform synchronous circular motion. The rotating disks 254 convert the circular motion into linear thrust through the connecting rod 255, pulling the sliding sleeve 257 to reciprocate linearly on the inclined guide rod 256. Since the defoliator 260 is fixed on the sliding sleeve 257, the defoliator 260 performs high-frequency up-and-down reciprocating motion, using its inertia and physical contact to peel and detach the leaves from the outer edge of the moss stem.

[0019] The drive motor 251 is a hydraulic motor, and the power is distributed to the transmission boxes on both sides via the bevel gear set 252. The gear pair in the transmission box drives the rotating disk 254 to rotate, and the connecting rod 255 pushes the sliding sleeve 257 to reciprocate up and down the guide rod 256 at an inclination of 30°. When the moss passes by, the leaf cover 260 quickly brushes downwards across the upper part of the moss, peeling off its large outer leaves in pieces, while the guide rod 256 is always higher than the top of the rotating disk, ensuring that the movement trajectory does not cause mechanical interference.

[0020] As a preferred technical solution, the blade shroud 260 has an adjustment structure on one side for adjusting the opening size, and the blade shroud 260 as a whole is made of elastic material.

[0021] The leaf remover 260 is made of highly elastic polyurethane or rubber material, which allows it to undergo elastic deformation when in contact with the moss stem. An adjustment structure, such as an adjustable bolt, is provided on one side of the leaf remover, which allows the operator to adjust the initial opening size of the leaf remover to accommodate moss varieties with different average thicknesses.

[0022] The leaf-removing cover, made of elastic material, can cushion and protect the delicate epidermis of the moss stems when peeling off the leaves at high speed, preventing damage to the commercial stems of the moss. The adjustable opening design allows the harvester to harvest both large-diameter, thick-stemmed moss stems and thinner varieties, improving the versatility of the equipment.

[0023] As a preferred technical solution, the harvesting component 200 also includes a belt-driven motor 220 and a belt steel frame 241 fixed on the steel frame 210, with the belt steel frame 241 connected to the steel frame 210. The two ends of the belt steel frame 241 are respectively provided with a first belt frame 230 and a second belt frame 231 for supporting the conveyor belt 240, and the output end of the belt power motor 220 is driven and connected to the conveyor belt 240.

[0024] A belt-driven motor 220 is mounted on a steel frame 210, and its output shaft is connected to the drive pulley of the conveyor belt 240. The belt frame 241, serving as the main load-bearing skeleton, is fixed to the overall steel frame 210, with a first belt bracket 230 and a second belt bracket 231 installed at its front and rear ends, respectively. These two belt brackets act as tensioning and support units, tensioning the conveyor belt 240 within a specific space. When the motor operates, it directly drives the belt to rotate cyclically along a predetermined trajectory.

[0025] The belt steel frame 241 forms a rigid suspension support with the first belt frame 230 and the second belt frame 231 at both ends, ensuring that the belt does not undergo serious deformation or derailment under heavy load.

[0026] As a preferred technical solution, the first belt frame 230 and the second belt frame 231 are both installed at the end of the belt steel frame 241, and a rotating plate 232 is coaxially installed at the bottom of the second belt frame 231 to push the blades that have detached from the blade cover 260 to the outside.

[0027] A rotating blade 232 that rotates synchronously with the pulley is installed coaxially at the end of the second belt frame 231, i.e., at the bottom of a specific inflection point or at the end of the conveyor track. When a large number of moss leaves peeled off by the leaf remover 260 fall or accumulate around the belt, the high-speed rotating blade 232 uses centrifugal force, similar to that of a fan blade or a deflector plate, to forcibly push these detached leaves to the outside sides of the harvester.

[0028] During continuous operation, a large number of moss leaves are peeled off. The plastic rotating plate 232, which rotates at high speed with the belt shaft, acts like a rotating broom, quickly whipping and throwing the fallen leaves to the outside of the furrows on the ground, keeping the bottom of the belt frame clean and preventing belt slippage caused by the accumulation of rotten leaves.

[0029] As a preferred technical solution, the steel frame 210 is provided with two sets of multiple inclined support rollers 242 on one side. The multiple inclined support rollers 242 are arranged at intervals along the transmission direction of the conveyor belt 240 and are supported on the inner side of the conveyor belt 240 so that the conveyor belts 240 on both sides maintain an inverted "V" shape structure.

[0030] On one side of the steel frame 210, multiple sets of inclined support rollers 242 are arranged at intervals along the belt conveying direction. These support rollers 242 have a specific inclination angle, and their roller surfaces directly abut against the inner non-working surface of the conveyor belt 240. Through multi-point distributed physical support, the originally flexible belt is forced to present an inverted "V" shaped groove structure that is wider at the top and narrower at the bottom in space.

[0031] It overcomes the shortcomings of flexible belts that are prone to collapse and deformation when clamping heavy objects, ensuring the stability of the inverted "V" shaped spatial structure throughout the entire stroke, thereby providing continuous and uniform clamping and lifting for the moss.

[0032] The conveyor belt 240 is approximately 1.5 meters long. On the steel frame 210, an inclined support roller 242, at a 30° angle to the horizontal plane, is installed every 20 centimeters. When multiple thick moss stalks simultaneously enter the belt clamping area, gravity attempts to flatten the belt, but due to the row of sturdy inclined support rollers 242 firmly holding it in place, the belt maintains a stable inverted "V" shape, and the moss stalks do not tilt.

[0033] As a preferred technical solution, the adjustment assembly includes a roller adjustment frame 243 rotatably connected to the inclined support roller 242, and an electrically controlled push rod disposed on the steel frame 210 and connected to the roller adjustment frame 243; The electrically controlled push rod drives the roller adjustment frame 243 to swing through its telescopic end, thereby driving the corresponding inclined support roller 242 to rotate, so that the two sets of conveyor belts 240 move synchronously inward or outward.

[0034] An electrically controlled push rod, such as an electric linear slider or hydraulic cylinder, is fixed to the steel frame 210. Its telescopic end is connected to the roller adjusting frame 243, which is connected to the inclined support roller 242. When the driver issues a control command from the cab, the electrically controlled push rod extends or retracts, driving the roller adjusting frame 243 to swing at a certain angle around a hinge point. The swinging of the roller adjusting frame causes the inclined support roller 242 on it to move synchronously inward or outward, thereby changing the distance between the two conveyor belts 240.

[0035] It now features the ability to dynamically adjust the belt spacing without stopping the machine, and can adjust the clamping force at any time according to the actual growth size of the moss in the field, greatly expanding the machine's adaptability to harvesting vegetables with uneven growth in the field.

[0036] When the harvester moves from a thin-stemmed moss ridge to a thick-stemmed moss ridge, the operator operates the system in the cab 100. The electronically controlled push rod receives a signal and initiates extension, pushing the roller adjustment frame 243 to swing outward. The inclined support rollers 242 on both sides then expand outward by 3 centimeters, widening the overall spacing of the inverted "V" shaped belts to accommodate the thicker moss and prevent the moss from being crushed due to excessive clamping.

[0037] As a preferred technical solution, each inclined support roller 242 is provided with a lower extension column 2421 at its bottom; Both ends of the multiple crossbars 600 are provided with side extension posts 610, and the middle of the side extension posts 610 is provided with a sliding groove for the lower extension post 2421 to pass through and slide. When the two sets of conveyor belts 240 move synchronously toward the middle, the lower extension column 2421 slides toward the middle of the crossbar 600.

[0038] Each inclined support roller 242 has a downwardly extending lower extension post 2421 at its axial bottom. Side extension posts 610 are located at both ends of the crossbar 600 below the belt, each with a long, narrow sliding groove. The lower extension post 2421 passes through this sliding groove. When the electrically controlled push rod in claim 7 drives the support roller 242 and the belt to move inwards, the lower extension post 2421 slides synchronously within the sliding groove of the side extension post 610 towards the geometric center of the crossbar 600. This precisely guides and transmits the lateral swing displacement of the belt, which is adjusted for width / narrowing, to the end of the crossbar 600. When the inclined support roller 242 moves inwards as a whole due to the reduced clamping gap, the lower extension post 2421 at its bottom slides inwards along the long grooves on the side extension posts 610 at both ends of the crossbar. The long grooves restrict the back-and-forth movement of the lower extension post, allowing it to slide precisely along the crossbar axial direction only, thus transmitting the lateral displacement to the interior of the crossbar without loss.

[0039] As a preferred technical solution, the lifting assembly includes a trigger rod 620; One end of the trigger rod 620 extends out of the crossbar 600 and is on the sliding track of one of the lower extension posts 2421. The lower extension post 2421 is made of magnetic material to attract the trigger rod 620. The other end of the trigger rod 620 extends into the interior of the crossbar 600 and is connected to the moving plate 630. The upper surface of the movable plate 630 is provided with multiple sets of wedges 640 connected, and the push column 650 slides vertically through the crossbar 600, with the bottom end of the push column 650 contacting and engaging with the inclined surface of the wedge 640. When the extension column 2421 slides toward the middle of the crossbar 600 and presses the trigger rod 620, the trigger rod 620 pushes the moving plate 630 and the wedge block 640 to move horizontally, and pushes the column 650 to slide upward and above the upper surface of the crossbar 600 through the pressure of the inclined surface.

[0040] The lower extension column 2421 uses a strong magnetic material such as a neodymium iron boron permanent magnet. When the two sets of belts move inward and the lower extension column 2421 slides towards the middle of the crossbar, it is quickly attracted by magnetic force and pushes the outer end of the trigger rod 620 located on its trajectory. The trigger rod 620 is squeezed and displaced inward into the crossbar 600, causing the internal moving plate 630 and multiple sets of wedges 640 to move horizontally. At this time, the bottom end of the push column 650, which is vertically inserted into the crossbar, climbs upward along the inclined plane of the wedge 640. Using the principle of the inclined plane, the horizontal displacement of the moving plate is converted into the vertical upward sliding of the push column 650, ultimately causing the push column 650 to protrude high above the upper surface of the crossbar 600.

[0041] As the extension post 2421 moves inward to its limit position due to the belt converging, its magnetic force firmly locks and pushes the trigger rod 620. The trigger rod pushes the stainless steel movable plate 630 inside the crossbar 2 cm to the left. The 45° slope wedge 640 on the movable plate then slides over the bottom of the push post 650. The push post 650 is forcefully pushed up 2 cm along the slope, rising above the surface of the crossbar. This row of protruding push posts presses against the bottom of the moss stem passing through this area, providing an upward step support force to prevent it from sliding down.

[0042] As a preferred technical solution, a separation gap is left between two adjacent crossbars 600 for the detached moss leaves to fall downwards.

[0043] The multiple crossbars 600 are not tightly connected in space, but rather, like louvers or fences, with a specific width of separation gap intentionally reserved between adjacent crossbars 600. When the moss leaves and debris detached by the leaf-removing mechanism fall into the crossbar area, under the action of gravity and machine vibration, these fragments fall directly through the gaps between the crossbars and onto the farmland surface below. This achieves self-weight physical screening during the conveying process. Waste leaves are discharged during the conveying process and do not enter the final collection bin with the commercial moss, greatly improving the cleanliness of the moss in the collection bin and reducing the cost of secondary manual sorting. The separation gap between two crossbars 600 is designed to be 5 centimeters. When the moss stems, due to their large size and diameter (usually greater than 5 centimeters), roll smoothly backward across the crossbars, the fragments of moss leaves detached by the leaf-removing cover, which are not wide or rigid enough, cannot stay and all fall through the 5-centimeter gap, directly falling back into the field as green manure.

[0044] As a preferred technical solution, the moss held and transported by the conveyor belt 240 falls onto the crossbar 600 after passing the rear end of the conveyor belt 240 and continues to be transported to the transport component 300, and is finally sent into the storage compartment 400 by the transport component 300.

[0045] First, the moss is cut and steadily conveyed by the inverted "V" shaped conveyor belt 240; When the moss reaches the rear end of the conveyor belt 240, i.e., the highest point of the conveyor or the turning release point, the belt is released from clamping. The moss fell onto the horizontal bar 600 below due to inertia and gravity; Supported by the crossbar and any protruding push columns, and pushed by the subsequent material, the moss continues to slide / transfer backward to the transport component 300, such as an inclined scraper conveyor belt. Finally, the clean dried moss is continuously delivered to the storage bin 400 by the transport component 300 for centralized storage.

[0046] In the final harvesting stage, a stalk of moss is held by a belt 240 and undergoes high-frequency defoliation. As it reaches the end of the belt, it is released and lies on a crossbar 600 with gaps. The remaining leaves fall through the gaps, while the clean stem slides onto a chain-type transport unit 300. The transport unit 300 lifts it 1 meter and then gracefully tosses it into a large-capacity collection bin 400. The entire process requires no manual handling or sorting, achieving highly efficient combined harvesting.

[0047] Working principle: The operator sits in the cab 100 and starts the belt-driven motor 220 and drive motor 251. The output of the belt-driven motor 220 rotates, driving the conveyor belt 240 to rotate. The output of the drive motor 251 is connected to a bevel gear set 252, which transmits power to the transmission boxes 253 on both sides. The transmission boxes 253 drive the rotating disk 254 to rotate. During the rotation of the rotating disk 254, the sliding sleeve 257 slides along the guide rod 256 via the connecting rod 255. The guide rod 256 is inclined and its height is always higher than the top of the rotating disk 254. During the sliding process, the sliding sleeve 257 can drive the leaf remover 260 on one side to move up and down reciprocally, which can remove the leaves from the moss stem. The leaf remover 260 is adjustable in size and made of elastic material, which can protect the stem of the moss stem.

[0048] A cutting blade 500 is also installed at the bottom of the drive frame 250 for cutting the moss stems. There are two sets of conveyor belts 240, which are placed above the cutting blades 500. The conveyor belts 240 are inclined and arranged in an inverted "V" shape on the side closest to each other to support and transport the moss stems. A belt steel frame 241 is set in the middle of the conveyor belt 240, which is connected to the steel frame 210. A first belt frame 230 and a second belt frame 231 are respectively set at both ends to support the conveyor belt 240. Multiple sets of inclined support rollers 242 are set on one side of the steel frame 210 to support the conveyor belt 240 so that the belt is in an inverted "V" shape. The conveyor belt 240 is positioned higher on the side closest to the cab 100. The lowest inclined support roller 242 is adjusted via a roller adjusting frame 243, which is controlled by an electrically controlled push rod. A lower extension column 2421 is located at the bottom of the inclined support roller 242. A crossbar 600 is located at the bottom of both sets of conveyor belts 240, with side extension columns 610 at both ends. A groove is formed in the middle of the side extension column 610, through which the lower extension column 2421 passes and can slide. The shortening of the extension end of the electrically controlled push rod pulls the roller adjusting frame 243 to rotate, thus inducing the inclined support roller 242. The inclined support roller 242 rotates, thereby driving the two sets of conveyor belts 240 to move synchronously towards the center. At this time, the lower extension column 2421 slides towards the center of the crossbar 600. One of the lower extension columns 2421 will quickly squeeze the trigger rod 620. The trigger rod 620 enters the crossbar 600. At this time, the moving plate 630 drives the wedge block 640 to move, thereby pushing the push column 650 to move upward, giving the moss stem an upward force to prevent the moss stem from sliding down. The synchronous movement of the two conveyor belts 240 towards the center can better clamp the moss stem and prevent it from sliding down, which is conducive to the stable transmission of the moss stem. The gap between the crossbars 600 can allow the moss stem leaves to fall off. After passing through the conveyor belts 240, the crossbars 600 are transmitted to the transport component 300 and then enter the storage bin 400.
