Description

Technical Field

[0001] This utility model relates to the field of sugarcane processing technology, and in particular to a sugarcane defoliation device. Background Technology

[0002] Currently, sugarcane is cultivated on a large scale, and large quantities of mature sugarcane are processed in batches. After harvesting, the surface of the mature sugarcane is covered with a lot of hairy leaves, which need to be removed. In the existing technology, an insertion-type sugarcane defoliator is generally used. The sugarcane is inserted into the feed port at one end of the defoliator, and the internal conveying mechanism and defoliation mechanism separate the sugarcane from the hairy leaves on its surface. However, during the process of inserting the sugarcane into the feed port, hairy leaves often block the feed port, which affects the long-term performance of the equipment.

[0003] A sugarcane defoliation device, disclosed in CN211581520U, includes a casing with a defoliation mechanism inside. An inlet and an outlet are located on opposite sides of the casing. A feeding seat and an outlet seat are fixed to the bottom of the outer walls of both sides of the casing, corresponding to the inlet and outlet positions, respectively. Both the feeding seat and outlet seat are arc-shaped. A limiting cylinder is fixed to the top outer wall of the feeding seat near the casing. An mounting cylinder is fixed to the top of the limiting cylinder's outer wall, and a rotating motor is fixed to one side of the mounting cylinder. A cleaning component is fixed to the output shaft of the rotating motor, and one end of the cleaning component is slidably connected to the top of the feeding seat. This invention inserts sugarcane into the limiting cylinder at the top of the feeding seat on one side of the casing. The rotating motor periodically rotates the cleaning component to dislodge the loose leaves on the feeding seat, preventing a large accumulation of leaves that could affect the long-term effectiveness of the equipment.

[0004] However, existing cleaning components can only clean the leaflets indirectly, and cannot simultaneously clean the leaflets during the leaf removal process. Utility Model Content

[0005] The purpose of this invention is to provide a sugarcane defoliation device that solves the technical problem that the cleaning components in the prior art can only clean the leaves indirectly and cannot clean the leaves simultaneously during the defoliation process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sugarcane defoliation device, comprising a casing and a belt conveyor, wherein the casing has an inlet and an outlet at its two ends, respectively, and a transmission platform is provided between the inlet and the outlet. The belt conveyor is located on the side closer to the inlet. A defoliation brush is provided inside the casing on the side closer to the inlet, and a leaf crushing mechanism is provided on the side closer to the outlet. The leaf crushing mechanism includes a scraper plate fixedly connected to the casing and located above the outlet. The scraper plate has multiple feeding grooves extending inward from the outer edge. A feeding shaft is provided in front of the scraper plate, and a feeding roller is provided on the feeding shaft. The feeding roller slides through the feeding grooves. A crusher is provided above the scraper plate. A leaf dropping port is opened behind the crusher in the casing, and a guiding mechanism is provided at the leaf dropping port.

[0007] Furthermore, the transmission platform includes a feeding platform and a discharging platform. The feeding platform is connected to the feeding port and extends upward at an angle from the feeding port. The discharging platform is connected to the rear of the feeding platform and extends downward at an angle from the rear of the feeding platform and is connected to the discharging port.

[0008] Furthermore, a guide arc plate is provided behind the feeding platform and above the unloading platform.

[0009] Furthermore, the scraper blade is located above the unloading platform and parallel to the unloading platform, the feeding roller is located between the scraper blade and the unloading platform, and the housing is provided with a feeding drive motor for driving the feeding roller to rotate.

[0010] Furthermore, the crusher is located behind the feeding trough, and the crusher includes a pair of symmetrically arranged crushing gears and a gear drive motor.

[0011] Furthermore, the material guiding mechanism includes a material guiding pipe located outside the leaf dropping inlet and a material guiding worm located inside the material guiding pipe, with one side of the material guiding pipe being open.

[0012] Furthermore, a discharge guide plate is provided at the opening, and the discharge guide plate extends outward away from the discharge port.

[0013] Furthermore, a worm gear motor is provided on the other side of the feed tube.

[0014] Furthermore, fixing rods are fixed at the four corners of the bottom outer wall of the housing, and the outer walls of the fixing rods are threaded with support tubes.

[0015] Furthermore, the bottom end of the support tube is fixed with a frustum-shaped support foot.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention solves the technical problem that existing cleaning components can only clean the leaf blades indirectly and cannot clean the leaf blades simultaneously during the leaf removal process.

[0018] Sugarcane enters the machine casing through the feed inlet. The leaves on the sugarcane are removed by the rotation of the defoliating brush. As the brush rotates, the defoliated sugarcane and leaves are moved towards the discharge outlet. This invention features a leaf crushing mechanism at the discharge outlet. A feeding roller rotates via a feeding shaft, lifting the leaves and placing them onto a scraper plate. The feeding roller slides across the scraper plate through a feeding trough, leaving the lifted leaves on the scraper plate. As the leaves accumulate on the scraper plate, they are swept away and crushed by a crusher located on the scraper plate. Finally, the crushed leaves fall from the leaf discharge outlet and are discharged outside the machine casing via a guiding mechanism. This allows for the defoliation of multiple sugarcane stalks with high efficiency. Simultaneously, leaf crushing prevents the defoliation channel from becoming clogged due to unremoved leaves, thus maintaining the efficiency of sugarcane defoliation. Attached Figure Description

The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0028] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0029] like Figures 1 to 5As shown, this utility model provides a sugarcane defoliation device. The machine casing 1 has an inlet 11 and an outlet 12 at both ends. A transmission platform 17 is provided between the inlet 11 and the outlet 12. A belt conveyor 2 is located near the inlet 11 to bring the sugarcane into the inlet 11. Inside the machine casing 1, near the inlet 11, there are three sets of defoliation brushes 4 arranged in parallel. All three brushes rotate clockwise, defoliating the sugarcane from the root. Facing the feed inlet 11, the defoliating brush 4 rotates clockwise to remove the leaves from the sugarcane. A leaf-crushing mechanism 6 is located near the discharge outlet 12. This mechanism includes a scraper plate 61 fixedly connected to the casing 1 and positioned above the discharge outlet 12. The scraper plate 61 has multiple feeding grooves 611 extending inwards from its outer edge. A feeding shaft 62 is located in front of the scraper plate 61, and a feeding roller 63 is mounted on the feeding shaft 62. The feeding roller 63 slides through the feeding trough 611. A crusher 64 is provided above the scraper blade 61. The housing 1 has a shredded leaf discharge port 65 located behind the crusher 64. A guiding mechanism 7 is provided at the shredded leaf discharge port 65. The feeding shaft 62 drives the feeding roller 63 to rotate counterclockwise. The feeding roller 63 picks up the shredded leaves and, with the rotation of the feeding roller 63, picks them up onto the scraper blade 61. The feeding roller 63 slides through the feeding trough 611 and over the scraper blade 61, and the picked leaves... The loose leaves remain on the scraper plate 61. As the loose leaves accumulate on the scraper plate 61, they are swept away and crushed by the crusher 64 located on the scraper plate 61. Finally, they fall out from the crushed leaf discharge port 65 and are discharged outside the machine casing 1 through the guiding mechanism 7. This enables the defoliation of multiple sugarcanes, resulting in high defoliation efficiency. At the same time, while defoliating the sugarcane, the loose leaves can be crushed simultaneously, avoiding the blockage of the defoliation channel inside the machine due to the loose leaves not being cleaned, which would affect the efficiency of sugarcane defoliation.

[0030] like Figures 1 to 3As shown, to ensure cleaner defoliation of the sugarcane and faster discharge from the outlet 12, the conveying platform 17 includes a feeding platform 13 and a discharging platform 14. The feeding platform 13 is connected to the inlet 11 and extends upward at an angle from the inlet 11. The discharging platform 14 is connected to the rear of the feeding platform 13 and extends downward at an angle from the rear of the feeding platform 13, connecting to the outlet 12. The upward angle of the feeding platform 13 provides upward resistance to the sugarcane, which effectively counteracts part of the pushing force of the defoliating brush 4 on the sugarcane, thereby extending the residence time of the sugarcane on the feeding platform 13 and providing more sufficient working time for the defoliating brush 4, ensuring more thorough and clean defoliation of the sugarcane. Furthermore, the discharging platform 14 is connected to the rear of the feeding platform 13, starting from the highest position of the feeding platform 13, thus creating a certain drop at the junction of the two. After the sugarcane has completed the defoliation process on the feeding platform 13, it falls naturally to the unloading platform 14 due to the drop. The unloading platform 14 extends downward at an angle to the discharge port 12. Utilizing gravity, the sugarcane can be discharged quickly and smoothly from the discharge port 12, greatly improving processing efficiency and achieving efficient connection and rapid turnover of the sugarcane defoliation and discharge process.

[0031] like Figure 1 and Figure 3 As shown, to ensure a smoother and more efficient transfer of sugarcane from the feeding platform 13 to the unloading platform 14, a guide arc plate 15 is provided behind the feeding platform 13 and above the unloading platform 14. The guide arc plate 15 is set on the top of the casing 1, located behind the feeding platform 13 and just above the unloading platform 14. After the sugarcane completes the leaf removal process on the feeding platform 13, it can smoothly and accurately slide down to the unloading platform 14 with the help of the reasonable guidance of the guide arc plate 15, effectively avoiding the jamming problem that may occur during the transfer of sugarcane, thereby ensuring the continuity and stability of the entire sugarcane processing process and improving production efficiency and processing quality.

[0032] To effectively improve the processing efficiency of leaf scraping, a feeding roller 63 is positioned above and parallel to the feeding platform 14, between the scraper plate 61 and the feeding platform 14. A feeding drive motor for driving the feeding roller 63 to rotate is provided on the housing 1. The scraper plate 61 is installed at the same downward angle as the feeding platform 14, and the feeding roller 63 is positioned in the space between the scraper plate 61 and the feeding platform 14. The housing 1 is equipped with a dedicated feeding drive motor to drive the feeding roller 63 to rotate. This allows the leaf scraping picked up by the feeding roller 63 and falling onto the scraper plate 61 to roll more quickly onto the crusher 64 behind it. This not only ensures that the scraper plate 61 can efficiently hold the leaf scraping, preventing it from scattering, but also greatly accelerates the conveying speed of the leaf scraping to the crusher 64, thereby significantly improving the cleaning efficiency of the crusher 64 and optimizing the entire process of leaf scraping.

[0033] like Figure 1 and Figure 2 As shown, the crusher 64 is located behind the feeding trough 611. The crusher 64 includes a pair of symmetrically arranged crushing gears and a gear drive motor. The pair of crushing gears are symmetrically distributed and work together to crush the material. Simultaneously, to ensure stable and efficient operation of the crushing gears, a gear drive motor is specially equipped. This motor provides strong power for the rotation of the crushing gears, driving the two crushing gears to rotate synchronously at a predetermined speed and direction. This allows the material conveyed from the front feeding trough 611 to be crushed quickly and effectively, ensuring a smooth and continuous material handling process, improving the equipment's production efficiency and processing quality, and meeting the actual needs of the production process.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, in order to collect the crushed leaves, a guiding mechanism 7 is installed at the leaf drop inlet 65. The guiding mechanism 7 includes a guiding pipe 71 located outside the leaf drop inlet 65 and a guiding worm 72 located inside the guiding pipe 71. One side of the guiding pipe 71 is an opening 73; a worm motor is located on the other side of the guiding pipe 71. The guiding pipe 71 is a hollow cylinder, and the guiding worm 72 is installed along the center line of the guiding pipe 71. The crushed leaves fall into the guiding pipe 71 through the leaf drop inlet 65, and the guiding worm 72 is driven by the worm motor. The rotation of the worm gear 72 guides the crushed leaves to fall out of the opening in the guide pipe 71. The continuous rotation of the worm gear 72 ensures continuous material discharge. Because the worm gear 72 can rotate continuously and stably, the discharge process of the crushed leaves can continue, thus ensuring that the equipment can efficiently, stably and uninterruptedly collect and discharge the crushed leaves. This greatly improves the overall working efficiency and material handling capacity of the equipment, effectively avoids equipment failures or material blockages that may be caused by the accumulation of crushed leaves, and ensures the smoothness and stability of the entire production process.

[0035] A discharge guide plate 74 is provided at the opening 73. The discharge guide plate 74 extends outward away from the discharge port 12, which guides the broken leaves to be discharged from the side of the housing 1 to avoid interference with the discharge port 12 of the housing 1. At the same time, the discharge guide plate 74 can facilitate the installation of bags.

[0036] This utility model provides a sugarcane defoliation device, aiming to solve the problem that the cleaning components in the prior art can only indirectly clean the leaves and cannot clean them simultaneously during the defoliation process. The device has a feed inlet 11 and a discharge outlet 12 at both ends of the casing 1, with a transmission platform 17 between them. On the feed inlet 11 side, there is a belt conveyor 2 and three sets of clockwise rotating defoliation brushes 4, which are used to feed the sugarcane roots towards the feed inlet 11 and defoliate them. On the discharge outlet 12 side, there is a leaf crushing mechanism 6, including a leaf scraper 61 fixed to the casing 1 and located above the discharge outlet 12. The plate has a feeding trough 611, a feeding shaft 62 and a feeding roller 63 are provided in front, and a crusher 64 is above. Behind the crusher 64, the casing 1 has a leaf crushing outlet 65 and a guiding mechanism 7. Sugarcane enters the machine casing 1 through the feed inlet 11. After being defoliated by the defoliating brush 4, it is carried to the discharge outlet 12 along with the loose leaves. The feeding roller 63 rotates counterclockwise to pick up the loose leaves to the scraper plate 61. After the loose leaves accumulate, they are rolled away and crushed by the crusher 64. They are discharged from the crushed leaf discharge outlet 65 through the guiding mechanism 7 outside the machine casing 1, realizing efficient defoliation of multiple sugarcane and simultaneous crushing of loose leaves, avoiding the blockage of the defoliation channel by loose leaves and affecting efficiency.

[0037] The conveying platform 17 consists of a feeding platform 13 and a discharging platform 14. The feeding platform 13 is connected to the inlet 11 and tilted upwards, creating upward resistance for the sugarcane, which partially offsets the pushing force of the defoliating brush 4, prolongs the residence time, and results in cleaner defoliation. The discharging platform 14 is connected to the rear of the feeding platform 13 and tilted downwards to the outlet 12. There is a drop at the connection point with the feeding platform 13, allowing the defoliated sugarcane to fall onto the discharging platform 14 using this drop and be quickly discharged from the outlet 12 by gravity, improving processing efficiency. To ensure smooth sugarcane transfer, a guide arc plate 15 is installed on the top of the machine casing 1, behind the feeding platform 13, and above the discharging platform 14 to guide the sugarcane to slide down precisely.

[0038] To improve the efficiency of leaf removal, a scraper plate 61 is installed above the feeding platform 14, parallel to it. A feeding roller 63 is located between the scraper plate 61 and the feeding platform 14, driven by a feeding drive motor on the casing 1. The scraper plate 61 is installed at an angle downwards, allowing the leaves picked up by the feeding roller 63 to roll faster towards the rear crusher 64, efficiently cleaning the leaves. The crusher 64 is located behind the feeding trough 611 and includes a pair of symmetrical crushing gears and a gear drive motor, enabling efficient material crushing. A guiding mechanism 7 is installed at the leaf drop inlet 65 and consists of an outer guiding pipe 71 and an inner guiding worm 72. One side of the guiding pipe 71 has an opening 73, and the other side has a worm motor. The crushed leaves fall into the guiding pipe 71, and the worm motor drives the guiding worm 72 to rotate, causing the leaves to continuously discharge from the opening 73, preventing accumulation and blockage, and ensuring efficient and stable operation of the equipment.

[0039] Example 2, as Figure 5As shown, a sugarcane defoliation device has four fixed rods 8 at the four corners of the bottom outer wall of the casing 1, and the outer wall of the fixed rods 8 is threaded with a support tube 81. The bottom end of the support tube 81 is fixed with a frustum-shaped support foot 82.

[0040] Working principle: By rotating the support tube 81, which is threaded to the outer wall of the fixed rod 8, the support height at the four corners of the bottom of the housing 1 can be adjusted, so that the device can be placed stably in the field according to the actual ground conditions.

[0041] In addition to the preferred embodiments described above, there are other embodiments of this utility model.
