Description

Technical Field

[0001] The present invention relates to a harvesting device, specifically a sugarcane harvester. Background Art

[0002] Sugarcane is one of the important raw materials for the sugar industry. Generally, sugar factories purchase sugarcane from growers and then carry out sugar-making processing.

[0003] Currently, sugarcane harvesting generally involves harvesting and cutting sugarcane into segments and selling them to sugar factories. Since the shelf life of segmented sugarcane is very short, the sugar factories need to process it as soon as possible. And the sugarcane in a certain range matures and is harvested at basically the same time, which will cause a huge workload for sugar factories during the harvesting period. Due to the above reasons, the selling price of segmented sugarcane is relatively low, which has a certain impact on the income of growers. At the same time, it is not conducive to the production of sugar factories. While harvesting the whole cane can extend the shelf life of sugarcane, reduce the pressure on sugar factories, and at the same time, can increase the income of growers. However, the existing equipment cannot harvest sugarcane as a whole root.

[0004] When harvesting sugarcane, the non-sugary tip needs to be removed, otherwise it will affect the selling price. The current tip-removing method is to remove the tip of sugarcane at a unified height through a cutting device. However, due to the individual differences of sugarcane plants, the heights of different sugarcane plants are different, and the heights and lengths of their tips are also different. If the cutting height is set too high, a large amount of non-sugary parts at the tips of sugarcane plants will not be removed cleanly. If the cutting height is set too low, a large amount of sugary parts will be removed, resulting in waste of sugar. In either case, it will affect the income of growers.

[0005] In addition, the existing sugarcane harvesting equipment is relatively large in volume and weight, and the overall length is also relatively long. When carrying out harvesting operations, the turning radius required is relatively large, resulting in inconvenient operation of the harvesting equipment. And when turning, it is impossible to avoid rolling over the ridges. Due to the large weight, serious damage will be caused to the ridges during rolling. The sugarcane roots remaining in the ridges will be fatally damaged, which will cause them to be unable to germinate and grow into complete plants again. Growers need to repair and replant the ridges, which will bring certain economic losses to growers. Summary of the Invention

[0006] The purpose of the present invention is to provide a sugarcane harvester to solve the problems that the existing sugarcane harvesting equipment cannot harvest sugarcane as a whole root, cannot accurately remove the tip, and is relatively large in weight and overall length.

DETAILED DESCRIPTION

[0039] like Figure 1 , Figure 2 As shown, the present invention includes a vehicle body 1, left and right straightening devices 2, front and rear straightening devices 3, a feeding device 4, a harvesting device 5, a laying device 6, and a leaf stripping and tipping device 7.

[0040] The vehicle body 1 includes a chassis, wheels, a cab, and an adjustment frame 8, which are used for installing various devices and moving.

[0041] The left and right straightening devices 2 are arranged at the front end of the vehicle body 1. When harvesting sugarcane, the sugarcane plants first pass through the left and right straightening devices 2, so that the sugarcane plants tilted to both sides are straightened from the left and right sides to the middle.

[0042] The front-to-back straightening device 3 is arranged at the rear of the front straightening device. After the sugarcane plants are straightened left and right, they are roughly in a vertical state in the left-right direction. However, some sugarcane plants may still be tilted in the front-to-back direction. Therefore, the front-to-back straightening device 3 is used to straighten them in the front-to-back direction, so that the sugarcane plants are basically in a vertical state when viewed from the front-to-back direction and the left-to-right direction.

[0043] The feeding device 4 is arranged behind the front and rear straightening devices 3. The straightened sugarcane is kept in a vertical state and enters the feeding device 4. For the sugarcane plants just entering the feeding device 4, the harvesting device 5 located below the front end of the feeding device 4 cuts off the sugarcane plants from the roots. After being cut, the sugarcane plants are kept in a vertical state and transported backward by the feeding device 4.

[0044] The laying device 6 is arranged at the rear of the feeding device 4 . After the vertical sugarcane plants reach the end of the feeding device 4 , the laying device 6 lays the vertical sugarcane backwards so that the upper part thereof enters the defoliating and tipping device 7 .

[0045] The de-leafing and de-pointing device 7 is arranged at the rear of the laying device 6, and performs de-pointing and de-leafing treatment on the sugarcane entering the device, and then outputs the processed whole sugarcane.

[0046] By using the sugarcane harvester of the present invention, the whole root of sugarcane can be harvested, and the tip part without sugar can be accurately removed.

[0047] Among them, Figure 3 , Figure 4 As shown, an adjustment frame 8 is provided at the front end of the vehicle body 1, and the left and right straightening devices 2 and the front and rear straightening devices 3 are installed on the adjustment frame 8. The adjustment frame 8 is installed on the vehicle body 1 through an adjustment mechanism, and the height of the adjustment frame 8 is controlled by the adjustment mechanism to adapt to different working environments (such as ridge height, etc.).

[0048] The left-right straightening device 2 includes two symmetrically arranged left-right straightening mechanisms, with a space for the plants to pass through left and right reserved between the two left-right straightening mechanisms. The plants are straightened left-right while passing through the space.

[0049] The left and right straightening mechanisms include a first sprocket 2-1 arranged at the front end of the vehicle body 1 and a second sprocket 2-2 located below the first sprocket 2-1, the second sprocket 2-2 is located in front of the first sprocket 2-1, and the second sprocket 2-2 is located on the outside of the first sprocket 2-1 in the left and right directions, and straightening chains 2-4 are installed on the first sprocket 2-1 and the second sprocket 2-2, and straightening and moving parts 2-5 for moving plants are distributed at intervals on the straightening chains 2-4.

[0050] While the uprighting chain 2-4 installed on the first sprocket 2-1 and the second sprocket 2-2 slopes forward and downward, its lower part also slopes outward. This causes the uprighting shifting member 2-5 installed on the uprighting chain 2-4 to move upward along the inclined straight line while also moving backward and inward.

[0051] The uprighting mechanism is used to upright the plants leaning to one side towards the middle. During operation, the entire uprighting mechanism moves forward at a certain speed. Since the uprighting chain 2-4 has a certain inclination angle in the left-right direction, when the chain moving forward with the adjusting frame 8 contacts the inclined plants, the plants are shifted by the uprighting mechanism. And the uprighting shifting member 2-5 moves backward at the same speed as the forward speed of the uprighting mechanism in the front-back direction. So the plants will not swing in the front-back direction and will only swing inward with the uprighting shifting member 2-5. When the plants pass through the entire uprighting mechanism, all the plants leaning to one side are uprighted.

[0052] Among them, the uprighting shifting member 2-5 includes a lever. The lever is directly fixed on the uprighting chain 2-4 or fixed on the uprighting chain 2-4 through a block. The lever is perpendicular to the plane where the uprighting chain 2-4 is located, and the lever extends inward in the left-right direction.

[0053] When the lever is fixed on the block, the block is fixed on the link of the uprighting chain 2-4. The block is located on the plane where the uprighting chain 2-4 is located, and the lever is fixed at the end of the block.

[0054] The inclined plants lean outward against the chain or the block. Since the chain is inclined, the plants will have a tendency to move forward when leaning against the chain or the block. The lever extending inward can hook the plants. During movement, the uprighting shifting member 2-5 moves relatively upward along the plants, so as to steadily shift the plants inward through the uprighting shifting member 2-5.

[0055] At the lower part of the adjusting frame 8, there is a forward-extending frame 2-3 extending forward and downward. The second sprocket 2-2 is installed at the front end of the forward-extending frame 2-3. The installation of the second sprocket 2-2 is achieved through the forward-extending frame 2-3 extending forward and downward.

[0056] Among them, generally, the first sprocket 2-1 is used as the driving sprocket 7-5 and the second sprocket 2-2 is used as the driven sprocket.

[0057] The axial directions of the first sprocket 2-1 and the second sprocket 2-2 are generally in the left-right direction, and the inclination angle of their axes is determined by the inclination angle of the chain straightening chain 2-4. When the sprockets drive the chain straightening chain 2-4 to move, the chain straightening and shifting member 2-5 continuously moves from the rear side of the chain straightening chain 2-4 to the front side and then to the rear side. Since the axes of the sprockets are inclined, although the lever of the chain straightening and shifting member 2-5 that moves to the rear side of the chain straightening chain 2-4 extends inward, compared with the chain straightening and shifting member 2-5 at the same height on the front side of the chain straightening chain 2-4, it is entirely located on the outer side. Therefore, the inclined plants can only contact the chain straightening and shifting member 2-5 on the front side of the chain straightening chain 2-4, and will not contact the chain straightening and shifting member 2-5 on the rear side of the chain straightening chain 2-4, thus avoiding the interference of the chain straightening and shifting member 2-5 on the rear side of the chain straightening chain 2-4 with the chain straightening operation.

[0058] In the chain straightening device of the present invention, a sprocket and chain structure is adopted. This structure is convenient to install. Only the positions of the first sprocket 2-1 and the second sprocket 2-2 need to be determined. The volume and weight of the sprockets and the chain are very small. At the same time, the required driving force and supporting force are also very small. The included angle between the chain straightening chain 2-4 and the horizontal plane can be designed to be relatively large. Different plants are shifted by different chain straightening and shifting members, and different plants will not affect each other. Compared with the existing chain straightening rollers, it has the advantages of light weight, small forward extension length, and convenient installation.

[0059] The front and rear chain straightening device 3 includes two symmetrically arranged front and rear chain straightening mechanisms. A space for the plants to pass through is left between the two front and rear chain straightening mechanisms. The front and rear chain straightening mechanisms include a third sprocket 3-1 provided on the vehicle body 1 and a fourth sprocket 3-2 located below the third sprocket 3-1. The fourth sprocket 3-2 is located in front of the third sprocket 3-1. A positioning chain 3-3 is installed on the third sprocket 3-1 and the fourth sprocket 3-2, and positioning shifting members 3-4 for shifting the plants are distributed at intervals on the positioning chain 3-3.

[0060] In order to avoid the adjusting frame 8 and facilitate the transmission of power more conveniently, a sprocket serving as a driving wheel is provided beside the fourth sprocket 3-2, and the positioning chain 3-3 bypasses this sprocket and is driven by this sprocket.

[0061] Among them, the inclination angle of the positioning chain 3-3 is very large to ensure that the front and rear inclined plants can be straightened towards the middle during operation. For the plants inclined forward, the plants contact the positioning shifting member 3-4 relatively late. However, due to the large angle of the positioning chain 3-3, after contact, the positioning shifting member 3-4 quickly straightens the plants backward during the upward movement; for the plants inclined backward, the plants contact the positioning shifting member 3-4 very early, and after contact, the positioning shifting member 3-4 straightens the plants forward.

[0062] The front and rear alignment mechanism moves forward at a certain speed together with the adjustment frame 8. For the plants that have been aligned left and right, if there is no tilt in the front and rear directions, the plants will directly pass through the front and rear alignment mechanism. If there is a tilt in the front and rear directions, during the movement of the front and rear alignment mechanism, the alignment toggle 3-4 that moves upward along the tilted alignment chain 3-3 from bottom to top will contact the plant and lift and align the tilted plant.

[0063] The alignment toggle 3-4 includes a lever. The lever is directly fixed on the alignment chain 3-3 or fixed on the alignment chain 3-3 through a stop block. The lever is parallel to the plane where the alignment chain 3-3 is located and perpendicular to the alignment chain 3-3.

[0064] When the alignment toggle 3-4 toggles the plant, there is no displacement in the left and right directions. Therefore, it is necessary that the third sprocket 3-1 and the fourth sprocket 3-2 do not shift in the left and right directions. So, the axles of the third sprocket 3-1 and the fourth sprocket 3-2 need to be set approximately in the front and rear direction. In this way, during operation, the alignment toggle 3-4 will move from the outside of the adjustment frame 8 to the inside of the adjustment frame 8, and then return from the inside of the adjustment frame 8 to the outside of the adjustment frame 8. The alignment toggle 3-4 that moves to the outside of the adjustment frame 8 will not interfere with the alignment toggle 3-4 on the inside.

[0065] The present invention further includes a leaf removing device 9. The leaf removing device 9 is arranged at the front part of the vehicle body 1 and is installed on the adjustment frame 8.

[0066] As Figure 1 、 Figure 2 and Figure 4 shown, for the first structure of the leaf removing device 9, the leaf removing device 9 is generally located between the left and right alignment device 2 and the front and rear alignment device 3. The leaf removing device 9 includes two groups of symmetrically arranged disk wheels 9-1. Each group contains two disk wheels 9-1, one above the other. A number of leaf removing ropes 9-2 are arranged around the circumference of the disk wheels 9-1. By the high-speed rotation of the disk wheels 9-1, the leaf removing ropes 9-2 whip and remove the leaves below the top of the sugarcane.

[0067] As Figure 10 、 Figure 11 and Figure 12 shown, another structure of the leaf removing device is that the first leaf removing wheel 9-3, the second leaf removing wheel 9-4 and the third leaf removing wheel 9-5 are sequentially arranged from top to bottom on the adjustment frames 8 on both sides. And the second leaf removing wheel 9-4 is located behind the first leaf removing wheel 9-3, and the third leaf removing wheel 9-5 is located behind the second leaf removing wheel 9-4.

[0068] At the top of the adjusting frames 8 on both sides, clamping mechanisms 9-6 are respectively provided. The clamping mechanism 9-6 includes a first driving wheel 9-11, a second driving wheel 9-12, and a third driving wheel 9-13 arranged on the adjusting frame 8. A first transmission member 9-14 is installed on the first driving wheel 9-11, the second driving wheel 9-12, and the third driving wheel 9-13. Poking members 9-15 are evenly distributed on the first transmission member 9-14. The first driving wheel 9-11, the second driving wheel 9-12, and the third driving wheel 9-13 are located in the same plane. The second driving wheel 9-12 is located inside the first driving wheel 9-11, and the third driving wheel 9-13 is located behind the second driving wheel 9-12.

[0069] The leaf-removing wheel includes a wheel disc 9-1 and leaf-removing ropes 9-2. A number of leaf-removing ropes 9-2 are evenly distributed around the wheel disc 9-1.

[0070] The three groups of leaf-removing wheels are distributed in sequence from top to bottom and are spaced apart in the front-rear direction. The sugarcane passes through the first leaf-removing wheel 9-3, the second leaf-removing wheel 9-4, and the third leaf-removing wheel 9-5 in sequence. The three groups of leaf-removing wheels perform leaf-removing treatment on the sugarcane plants in sequence from top to bottom. While the leaf-removing wheels whip and remove the leaves on the sugarcane downward, they also flick the weeds on the ground outward to remove them. While realizing sugarcane leaf-removing, the weeds on the ridges are also treated, and the leaves and weeds can be discharged to prevent the weeds and leaves from affecting the subsequent processes.

[0071] The front-rear straightening device 3, the left-right straightening device 2, and the leaf-removing device 9 of the present invention are all powered and distributed by a power distribution box installed on the adjusting frame 8.

[0072] As Figure 5 shown, the feeding device 4 includes two parallel clamping and conveying mechanisms up and down. The clamping and conveying mechanism includes two mounting frames 4-1 arranged symmetrically left and right. Belt wheels 4-2 are provided at the front and rear ends of the mounting frame 4-1. A belt 4-3 is installed on the two belt wheels 4-2. The two belts 4-3 are arranged adjacent to each other. A poking mechanism is provided at the front end of the clamping and conveying mechanism. The poking mechanism is used to poke the plants into the clamping and conveying mechanism.

[0073] Each clamping and conveying mechanism includes two mounting frames 4-1 arranged symmetrically left and right. Belt wheels 4-2 are provided at the front and rear ends of the mounting frame 4-1. The rotating shaft 7-1 of the belt wheel 4-2 is installed on the lower side surface of the mounting frame 4-1. A belt 4-3 is installed on the two belt wheels 4-2. One of the belt wheels 4-2 serves as a driving wheel to drive the belt 4-3 to move. The two belts 4-3 are arranged adjacent to each other, and the moving directions and moving speeds of the two belts 4-3 are the same. A small gap is left between the two belts 4-3. When the plants of the rod-shaped crops pass through this gap, they are clamped by the two belts 4-3 on both sides and then move backward together with the belts 4-3.

[0074] A material pushing mechanism is arranged at the front end of the clamping and conveying mechanism. There are two material pushing mechanisms which are symmetrically arranged. The material pushing mechanisms are located between the upper and lower clamping and conveying mechanisms. When the plants approach the front end of the conveying device, the material pushing mechanisms push the plants backward, so as to send the plants into the clamping and conveying mechanism, and the clamping and conveying mechanism clamps and conveys them backward.

[0075] The material pushing mechanism includes two material pushing sprockets 4-4. The two material pushing sprockets 4-4 are arranged along the length direction of the mounting frame 4-1. A material pushing chain 4-5 is mounted on the two material pushing sprockets 4-4, and material pushing blocks 4-6 are distributed at intervals on the pushing chain. The moving direction and speed of the material pushing chain 4-5 are the same as those of the belt 4-3. There is a certain distance between the two material pushing sprockets 4-4, so that the plants are jointly conveyed backward by the clamping and conveying mechanism and the material pushing mechanism at the beginning. When the plants are completely clamped, the plants gradually leave the material pushing mechanism and are completely conveyed backward by the clamping and conveying mechanism.

[0076] The harvesting device 5 includes a cutting frame 5-1. The cutting frame 5-1 is directly mounted on the chassis of the vehicle body 1. Two cutters 5-2 with their cutting edges approaching each other are arranged on the cutting frame 5-1. The harvesting device 5 is located directly below the front end of the clamping and conveying mechanism and is used to cut off the plants that have just entered the clamping and conveying mechanism from the lower part. At this time, the plants are in a vertical state. After the plants are cut off, the plants remain in a vertical state and are conveyed backward by the feeding device 4.

[0077] The cutting frame 5-1 can adjust the height of the cutters 5-2. The two circular cutters 5-2 approach each other. When the plants pass between the two cutters 5-2, the two cutters 5-2 cut off the plants.

[0078] Among them, the left-right straightening device 2 and the front-back straightening device 3 jointly form the straightening treatment part of the sugarcane, which straightens the sugarcane in the left-right direction and the front-back direction. At the same time, the front-back straightening device 3 and the feeding device 4 jointly form the proper-position feeding treatment part of the sugarcane. After the sugarcane is straightened left and right, the adjacent plants are separated and queued through the front-back straightening device 3 and the material pushing mechanism. The plants are successively straightened front and back by the material pushing mechanism while the adjacent plants are separated, and then the plants are successively pushed into the feeding device 4 by the material pushing mechanism. In this way, the plants entering the feeding device 4 are spaced apart from each other and will not be close together in two or more. The queued plants are successively conveyed backward by the feeding device 4. During the conveying process, since the plants are clamped and conveyed forward by the upper and lower clamping and conveying mechanisms at the same time, that is, the plants are simultaneously subjected to two parallel forces, the plants will translate along the directions of these two forces, and the plants always remain in a vertical state during the conveying process.

[0079] Such as Figure 6As shown, the reclining device 6 includes two reclining sprockets 6-1 provided on the vehicle body 1. A reclining chain 6-2 is installed on the two reclining sprockets 6-1. Reclining blocks 6-3 are distributed at intervals on the reclining chain 6-2. The reclining chain 6-2 is arranged obliquely up and down. A horizontal reel 6-6 is provided on the vehicle body 1. The reel 6-6 is located below the front end of the reclining chain 6-2. Universal joints 6-4 are respectively provided on the axle of the upper reclining sprocket 6-1 and the axle of the reel 6-6. The two universal joints 6-4 are connected to each other by a connecting shaft 6-5.

[0080] A number of reel teeth 6-7 are evenly distributed around the axis on the reel 6-6.

[0081] As Figure 7 、 Figure 8 As shown, the leaf stripping and tip removing device 7 includes a leaf stripping and tip removing mechanism provided on the vehicle body 1. The leaf stripping and tip removing mechanism includes four parallel rotating shafts 7-1. Drums 7-2 are respectively provided on each rotating shaft 7-1. A number of flexible paddles 7-3 are distributed around the axis on the surface of the drum 7-2. The rotating shafts 7-1 are grouped in pairs of two. The processing channel for the sugarcane to pass through is between the two groups of rotating shafts 7-1. When the sugarcane passes through the processing channel, the leaves on the surface of the sugarcane and the sugarcane body are dialed by the flexible paddles 7-3. A feeding mechanism for driving the sugarcane to pass through the processing channel of the leaf stripping and tip removing mechanism is provided on the leaf stripping and tip removing mechanism. A transmission mechanism is provided at one end of the leaf stripping and tip removing mechanism for transmitting power to drive the feeding mechanism and the leaf stripping and tip removing mechanism.

[0082] Generally, the processing channel of the leaf stripping and tip removing mechanism is in a vertical state, and the sugarcane passes through the processing channel from top to bottom.

[0083] The feeding mechanism is provided in the middle of one group of rotating shafts 7-1. The feeding mechanism includes feeding sprockets 7-4 provided on the two rotating shafts 7-1. The feeding sprockets 7-4 are rotatably connected to the rotating shafts 7-1 where they are located. A driving sprocket 7-5 is provided on one side of the rotating shaft 7-1. A feeding chain 7-7 is installed on the feeding sprockets 7-4 and the driving sprocket 7-5. Feeding blocks 7-8 are arranged at intervals on the feeding chain 7-7. The driving sprocket 7-5 is connected to the transmission mechanism through a transmission shaft 7-12.

[0084] The feeding mechanism includes feeding sprockets 7-4 mounted on two rotating shafts 7-1. The feeding sprockets 7-4 are rotatably connected to the rotating shafts 7-1 they are on, and the rotation of the feeding sprockets 7-4 and the rotation of the rotating shafts 7-1 do not affect each other. On one side of the rotating shaft 7-1, a driving sprocket 7-5 and a turning sprocket 7-6 are provided. A feeding chain 7-7 is installed on the feeding sprocket 7-4, the driving sprocket 7-5, and the turning sprocket 7-6. The driving sprocket 7-5 is connected to a transmission mechanism through a transmission shaft 7-12, and the power of the transmission mechanism is transmitted to the driving sprocket 7-5, which drives the movement of the feeding chain 7-7. Feeding blocks 7-8 are arranged at intervals on the feeding chain 7-7. The feeding blocks 7-8 are evenly distributed along the feeding sprocket 7-4. Through the feeding blocks 7-8, sugarcane can be conveyed at a certain speed through the processing channel.

[0085] The two rotating shafts 7-1 in one group rotate in the same direction. For the rollers 7-2 on the rotating shafts 7-1 of this group, the moving direction of the flexible flaps 7-3 on the side of the processing channel is the same as the moving direction of the sugarcane. The two rotating shafts 7-1 in the other group rotate in opposite directions. For the rollers 7-2 on the rotating shaft 7-1 at the inlet end of the processing channel, the moving direction of the flexible flaps 7-3 on the side of the processing channel is the same as the moving direction of the sugarcane.

[0086] At the entrance of the processing channel, the rollers 7-2 of the two rotating shafts 7-1 push from the outside to the inside and downward of the processing channel. The rotation speed of the rollers 7-2 is much greater than the speed at which the sugarcane moves downward along the processing channel. Thus, a downward force is applied to the sugarcane by the flexible flaps 7-3. After the tip of the sugarcane is removed or the leaves on the surface of the sugarcane are removed by the downward force, the removed objects are conveyed downward. The two rotating shafts 7-1 at the exit of the processing channel rotate in opposite directions. One rotates from the inside to the outside and downward of the processing channel, and the other rotates upward on the inside of the processing channel. In this way, the sugarcane rotates at a certain angle around its own axis under the action of the rolling in opposite directions on both sides, so that the sugarcane can be defoliated comprehensively and without dead corners, preventing the drawback that only the two sides of the sugarcane can be defoliated. At the same time, for the two rotating shafts 7-1 on one side and rotating in opposite directions, the rollers 7-2 on the two rotating shafts 7-1 can both dial the removed objects between the two rotating shafts 7-1 and discharge them outward, so as to realize the discharge of sundries during the processing process.

[0087] Such as Figure 9As shown in the figure, the transmission mechanism is located at one end of the leaf stripping and tip removing mechanism. The transmission mechanism includes drive sprockets 7-9 provided at the ends of each rotating shaft 7-1. All the drive sprockets 7-9 are connected by a drive chain 7-10. The rotation direction of the rotating shaft 7-1 as described above is achieved through the winding direction of the drive chain 7-10 and by adding a steering sprocket. Power can be directly input into the transmission mechanism, or it can be first delivered to one of the rotating shafts 7-1, and then the power distribution is realized through the transmission mechanism.

[0088] One of the rotating shafts 7-1 is connected to the feeding mechanism through a sprocket chain reduction mechanism 7-11. The sprocket chain reduction mechanism 7-11 is connected to the drive sprocket 7-5 of the feeding mechanism through a transmission shaft 7-12. The sprocket chain reduction mechanism 7-11 has two stages. After two-stage reduction, there is a large speed difference between the drum 7-2 on the rotating shaft 7-1 and the feeding paddle 7-8 of the feeding mechanism. This speed difference can be adjusted through the sprocket chain reduction mechanism 7-11.

[0089] The flexible paddle 7-3 is made of materials with a certain flexibility such as rubber and plastic. A number of convex ridges are distributed on the surface of the flexible paddle 7-3. The length direction of the convex ridges is parallel to the axis direction of the rotating shaft 7-1. The friction between the flexible paddle 7-3 and the surface of the sugarcane is increased through the convex ridges on the surface of the flexible paddle 7-3, so as to better remove leaves and tips.

[0090] An aggregate bin is arranged below the leaf stripping and tip removing mechanism, and a straw discharge guide plate is arranged on one side of the leaf stripping and tip removing mechanism. The sugarcane processed by the leaf stripping and tip removing mechanism falls downward into the aggregate bin, while the tips, leaves and other sundries generated during the processing are discharged outward through the straw discharge guide plate.

[0091] The leaf stripping and tip removing device 7 of the present invention utilizes the self-characteristics of sugarcane. After maturity, the sugar-free tip of the sugarcane dehydrates and withers, and the connection point between the sugar-containing stem and the sugar-free tip is the weakest position in terms of force. When a certain external force is applied to the sugarcane plant, this position is always the first to break. By applying an external force to the sugarcane to break the tip of the sugarcane, the sugar-free tip part of the sugarcane can be accurately removed. The present invention enables the sugarcane to pass through the processing channel of the leaf stripping and tip removing mechanism at a certain speed. During the process of passing through the leaf stripping and tip removing mechanism, the flexible paddle 7-3 on the drum 7-2 quickly pats the surface of the sugarcane, thereby applying an external force to the sugarcane. After the sugarcane is subjected to the external force, the connection point between its stem and tip breaks due to being unable to bear the external force, thus realizing the tip removing operation of the sugarcane.

[0092] Although the positions of the connection points between the stalks and the tips of different sugarcane plants are different, the leaf stripping and tip removing mechanism of the present invention has a certain length. When sugarcanes of different heights are laid forward around a point, the upper parts of the sugarcanes can all completely pass through the leaf stripping and tip removing mechanism, and the connection points between the tips and the stalks of the sugarcanes are within the length range of the leaf stripping and tip removing mechanism. After passing through the leaf stripping and tip removing mechanism, the connection points between the stalks and the tips are all fractured, so as to adapt to sugarcane plants of different heights and different positions of the connection points between the tips and the stalks.

[0093] Since the sugarcane's sugar-free tip can be accurately removed, the remaining part has a high sugar content, a high selling price, and the sugary part will not be removed, thus avoiding losses and maximizing the benefits. At the same time, during the process of removing the tip of the sugarcane by the leaf stripping and tip removing mechanism, since the flexible flap 7-3 continuously and rapidly pats the surface of the sugarcane, the leaves on the sugarcane are thus knocked off, realizing the leaf removing operation of the sugarcane, obtaining a clean and complete plant without impurities, and having a high price when sold, maximizing the benefits of sugarcane growers.

[0094] An engine is installed on the vehicle body 1. The power of the engine is used not only to drive the movement of the vehicle body 1 but also to drive the operation of the leaf stripping and tip removing device 7, etc.

[0095] The sugarcane harvester of the present invention is used for harvesting the whole sugarcane root and has the characteristics of miniaturization and integration.

[0096] The harvester of the present invention harvests one row of sugarcane plants each time. The sugarcane plants pass through the front and rear straightening devices 3 and the left and right straightening devices 2 in sequence, so as to straighten the sugarcane into an approximately vertical state. While straightening, the lower leaves of the sugarcane are removed by the leaf removing device 9, and then enter the feeding device 4. When just entering the feeding device 4, the sugarcane is cut off from the root by the harvesting device 5 below. The cut sugarcane is kept in a vertical state and conveyed backward by the feeding device 4. When the sugarcane reaches the end of the feeding device 4, it is laid backward around its root by the laying device 6. The upper part of the laid sugarcane enters the leaf stripping and tip removing device 7, and the tip of the sugarcane is removed by the leaf stripping and tip removing device 7, and at the same time, the upper leaves of the sugarcane are removed. Finally, the complete and clean whole sugarcane plant is discharged from the leaf stripping and tip removing device 7 and collected.

[0097] The present invention can realize the automatic harvesting of the whole sugarcane plant and can accurately remove the sugar-free tip at the upper end of the sugarcane. At the same time, the volume and weight of the harvester of the present invention are relatively small, the overall length is small, it is easy to operate and has a small turning radius, and it will not cause serious damage to the ridges and the roots of the sugarcane. The present invention can maximize the benefits of sugarcane harvesting, extend the shelf life of sugarcane, reduce the impurity content in sugarcane, and will not cause sugar loss.
