Abstract
Description
Technical Field
[0001] This invention relates to a dual-channel automatic lotus root fiber extraction device comprising a frame, a feeding unit, a lotus root stem conveying unit, a lotus root stem fiber extraction unit, and a lotus root fiber collection unit, belonging to the technical field of lotus root fiber extraction and agricultural product processing equipment. Background Technology
[0002] Lotus root fiber, also known as lotus root silk fiber, refers to the naturally grown and elongated tubular fibers of the secondary wall portion of the lotus root stem (the stem between the lotus leaf or seedpod and the lotus root). It is a natural material widely used in textiles, food, and chemicals. As a primary ingredient in ink paste, lotus root silk is highly valued, with its product, "Longquan Ink Paste," being even more expensive than gold. The market for lotus root silk products is vast, while the supply of raw lotus root silk falls short of demand. Therefore, there is an urgent need to develop equipment for extracting lotus root silk to effectively utilize this resource.
[0003] Currently, there are several methods for extracting lotus root fibers: (1) Manual extraction in small workshops. Craftsmen break the lotus root stems directly and collect the fibers manually. The advantage is that the operation is simple, but the disadvantage is that manual extraction is time-consuming and labor-intensive, with high labor costs and low efficiency. Moreover, freshly harvested lotus root stems need to be broken off quickly for extraction, and once the lotus root stems are dehydrated, it is difficult to extract the fibers. (2) Automatic fiber extractor for lotus root stems. Patent CN202211071431.8 uses a single-channel propulsion motor for feeding, a rotating motor in conjunction with a cutter for cutting, and collects the lotus root fibers by winding them around a fiber-collecting claw. The disadvantages of this type of device are: First, it requires manual filling of lotus root stems and manual cleaning of waste lotus root stems, and the single-channel design can only process one lotus root stem at a time, resulting in high labor costs and low efficiency; Second, it does not clean and moisturize the lotus root stems, and the fiber extraction effect is not good after the lotus root stems are dehydrated; Third, it has high requirements for the cylindricity of the lotus root stems themselves, uses a large number of propulsion motors, and the equipment is relatively complex, with high costs and maintenance costs; Fourth, the fiber-collecting claws are prone to fiber detachment and cannot collect all exposed lotus root fibers.
[0004] To overcome the above problems, this invention discloses a dual-channel automatic lotus root fiber extraction device. It comprehensively considers and upgrades the shortcomings of the aforementioned two lotus root fiber extraction methods, innovatively employing an automated feeding unit integrating cleaning and temperature control functions, a highly efficient and adaptable dual-channel lotus root stem conveying unit, a highly compatible lotus root stem fiber extraction unit, and a lotus root fiber collection unit with a high fiber collection rate. This ensures the freshness of the lotus root stems to improve the fiber extraction effect, while also increasing the efficiency of lotus root fiber extraction and enhancing the practicality of the device. Summary of the Invention
[0005] This invention addresses the problems of high labor costs, poor fiber extraction after dehydration of lotus stems, high requirements for the thickness and cylindricity of lotus stems, and inability to collect all exposed lotus stem fibers in existing lotus root fiber extraction devices. It provides a dual-channel automatic lotus root fiber extraction device. The automated feeding unit reduces manual operation, the washing tank keeps the lotus stems moist to ensure good fiber extraction, the dual-channel lotus stem conveying unit improves fiber extraction efficiency, the elastic lever improves the device's compatibility, and the complex winding trajectory of the fiber collecting rod ensures effective lotus root fiber collection.
[0006] This invention addresses the problems of existing lotus root fiber extraction devices by making fundamental innovations. The basic ideas are: ① A conveyor belt is designed in the feeding unit to automatically fill the lotus root stalks, and a washing tank and diversion port are designed to clean, moisturize, and divert the stalks, thereby improving fiber extraction efficiency. ② A clamping and limiting mechanism and the deformation of elastic levers are used to clamp and release the lotus root stalks. ③ The lotus root fiber collection mechanism is installed at a 30-degree angle on the scissor lift platform, improving the utilization of the working area of the fiber collecting rod. Combined with the complex fiber entanglement trajectory generated by the rotation and self-rotation of the collecting rod, efficient collection of lotus root fibers is ensured.
[0007] To achieve the above objectives and principles, the technical solution of the present invention is as follows:
[0008] A dual-channel automatic lotus root fiber extraction device consists of five parts: frame 1, feeding unit 2, lotus root stem conveying unit 3, lotus root stem fiber extraction unit 4, and lotus root fiber collection unit 5.
[0009] The frame 1 includes a base 101, side mounting brackets 102, a top mounting bracket 103, a control console 104, and a vision sensor 105. The base 101 is located at the bottom of the device. The side mounting brackets 102 are located on the left and right sides of the base. The top mounting bracket 103 is located at the top of the device. The control console 104 is located on the top mounting bracket and controls the operation of the device. The vision sensor 105 is located on the side mounting bracket 102 and is used to monitor the position of the lotus root stalks.
[0010] The feeding unit 2 includes a feeding bin 201, an upper electric conveyor belt 202, a lower electric conveyor belt 203, an air pump cleaner 204, and a temperature controller 205.
[0011] The feeding bin 201 is welded to the top mounting frame 103 and is divided into upper and lower layers. It is equipped with a lotus root inlet A located on the top left side of the feeding bin 201. The upper left side of the feeding bin 201 is a cleaning pool filled with a suitable depth of cleaning liquid. A pair of air inlets D are located on the upper left side of the feeding bin 201. The air pump cleaners 204 are a pair and are set on the left outer shell of the feeding bin 201, connected to the air inlets D. The upper electric conveyor belt 202 is placed at an angle in the cleaning pool, and its inclined top is connected to the diversion port B. The diversion port B is located in the middle of the upper layer of the feeding bin 201. The lower electric conveyor belts 203 are a pair and are symmetrically placed on the left and right sides of the lower layer of the feeding bin 201, respectively connected to a pair of discharge ports C located on the left and right sides of the bottom of the lower layer of the feeding bin 201.
[0012] The air pump cleaner 204 can spray air into the cleaning tank, causing the lotus root stems to tumble and be cleaned. At the same time, the sprayed air agitates the water flow in the cleaning tank, and in conjunction with the inclined upper electric conveyor belt 202, it can automatically and orderly push the lotus root stems to the diversion port B. The temperature controller 205 is located in the cleaning tank on the left side of the upper layer of the feeding hopper 201. It can adjust the cleaning solution to a suitable working temperature, replenish the moisture of the lotus root stems, activate the elasticity of the lignocellulose in the lotus root fibers, and avoid the problem of poor fiber drawing caused by dehydration of the lotus root stems.
[0013] The lotus root conveying unit 3 includes a conveyor belt mounting base 301, a motor 302, a drive shaft 303, a drive wheel 304, a belt 305, a lotus root conveying groove 306, a driven wheel 307, a driven shaft 308, and a clamping and limiting mechanism 309.
[0014] The conveyor belt mounting bases 301 are a pair, symmetrically welded to the inner side mounting bracket 102; the motor 302 is mounted on the outer side mounting bracket 102 via a motor mounting bracket, and the motor 302 is connected to the drive shaft 303 via a coupling, driving the drive shaft 303 to rotate; the drive wheels 304 are a pair, keyed and assembled on the drive shaft 303, and form a belt drive with the driven wheel 307 via a belt 305; the driven wheel 307 is keyed and mounted on the driven shaft 308; the lotus root conveying groove 306 is bolted to the conveyor belt mounting base 301, blocking the lotus roots conveyed on the belt 305, and providing lateral constraint.
[0015] The clamping and limiting mechanism 309 is located at the end of the lotus root conveying groove 306 and includes a hinge support 3091, a fixed limiting post 3092, a movable limiting post 3093, a movable roller 3094, a connecting rod 3095, a gear and rack 3096, and a motor 3097.
[0016] The hinge support 3091 is a pair of hinge bases spaced 35mm apart, which are welded onto the top mounting bracket 103. The fixed limiting post 3092 is connected to one side of the hinge support 3091 via a hinge and is fixedly installed. The movable limiting post 3093 is connected to the other side of the hinge support 3091 via a hinge. Unlike the fixed limiting post 3092, the rod of the movable limiting post 3093 is connected to the gear rack 3096 via a connecting rod 3095 and is powered by a motor 3097. This allows control of the opening and closing action of the rod of the movable limiting post 3093, which is better adapted to the clamping of lotus root stalks of different thicknesses.
[0017] The fixed limiting post 3092 and the movable limiting post 3093 are both equipped with movable rollers 3094 at their bottom ends, which facilitates the conveying of lotus root stalks by squeezing and rolling.
[0018] The lotus root stalk extraction unit 4 includes a linear movement module 401, a mounting column 402, a fixed shaft 403, a cutting module 404, a crank-slider module 405, and a waste processing module 406.
[0019] The linear movement module 401 is mounted on the base 101, and its linear movement direction is on the same straight line as the lotus root feed direction;
[0020] The mounting post 402 is mounted on the linear module 401 by bolts;
[0021] The fixed shaft 403 is fitted onto the mounting post 402. The main shaft 4031 has an L-shaped air hole E inside, and two elastic paddles 4032 are symmetrically distributed at its end. The two elastic paddles 4032 form a hand-held, trumpet-shaped structure, which facilitates the insertion and centering of the lotus root stem, reduces the requirement for the cylindricality of the lotus root stem, and has micro barbs on its inner side and air holes for easy cleaning.
[0022] The cutting module 404 includes a motor 4041, a bearing seat 4042, a pinion 4043, a gear 4044, an annular guide groove 4045, a front tool mounting seat 4046, a rear tool mounting seat 4047, a tool arm 4048, and a tool 4049.
[0023] The motor 4041 is bolted to the top of the mounting column 402. Its output shaft is connected to the pinion 4043 via a bearing seat 4042, driving the pinion 4043 to rotate. The pinion 4043 meshes with the large gear 4044. The large gear 4044 is mounted on the fixed shaft 403 with a clearance fit. Four solid steel bars are welded to its end face. The solid steel bars pass through four small holes evenly distributed along the circumference on the front mounting base 4046 of the tool and are welded to the rear mounting base 4047 of the tool. The annular guide groove 4045 is welded to the front mounting base 4046 of the tool, and a three-quarter spherical guide groove is opened on its circumference. The tool arm 4048 is bolted to the front mounting base 4046 of the tool and the tool 4049. The tail of the tool 4049 is bolted to the rear mounting base 4047 of the tool. The cutting angle of the tool 4049 can be adjusted with the linear movement of the annular guide groove 4045.
[0024] The small gear 4043 meshes with the large gear 4044 to drive the entire cutting module 404 to rotate, and works with the cutter 4049 to complete the circumferential cutting function. The tooth thickness of the small gear 4043 is significantly thicker than that of the large gear 4044, so that the large gear 4044 has linear movement space.
[0025] The crank-slider module 405 includes a motor 4051, a bearing housing 4052, a pinion 4053, a large gear 4054, a connecting rod 4055, and a spherical slider 4056. The motor 4051 is bolted to the mounting post 402, and its output shaft is connected to the pinion 4053 through the bearing housing 4052. The pinion 4053 meshes with the large gear 4054 for transmission. The large gear 4054 is connected to the spherical slider 4056 through the connecting rod 4055 and transmits power to the spherical slider 4056. The spherical slider 4056 is fitted into an annular guide groove 4045 and is constrained by a three-quarter spherical guide rail groove on the annular guide groove 4045. The spherical slider 4056 can drive the annular guide groove 4045 to achieve reciprocating linear motion without hindering the rotational motion of the cutting module 404.
[0026] The waste processing module 406 is arranged on the side of the mounting column 402 and includes an air pump 4061 and a conduit 4062. One end of the conduit 4062 is connected to the air pump 4061, and the other end is inserted into the air hole left on the mounting column 402. The air hole of the mounting column 402 is connected to the L-shaped air hole E in the fixed shaft 403, so that the high-pressure gas generated by the air pump 4061 can flush the lotus root residue in the fixed shaft 403.
[0027] The elastic paddles 4032 are a pair, forming a hand-held trumpet shape, which can guide the lotus root stem to enter the center, and the barbs on them can prevent the lotus root stem from sliding out; the crank slider module 405 can drive the annular guide groove 4045 and the front mounting seat of the cutter 4046 to squeeze the rear mounting seat of the cutter 4047 together, so that the rear mounting seat of the cutter 4047 pushes forward to squeeze the elastic paddles 4032 at the front end of the fixed shaft 403 and deforms and tightens them, which can adapt to the clamping and shrinking process of lotus root stems with different cylindricity, and can be used even if the lotus root stem has a large curvature; the cutting module 404 rotates so that the cutter 4049 makes an annular cut on the surface of the lotus root stem to an appropriate depth; the linear movement module 401 can move backward so that the lotus root stem cut in the annular shape is broken off, exposing the lotus root fibers.
[0028] The lotus root silk collection unit 5 includes a scissor-type lifting platform 501 and a lotus root silk extraction mechanism 502;
[0029] The scissor lift platforms 501 are a pair, set on the base 101, and can move up and down; the lotus root silk extraction mechanism 502 is welded to the scissor lift platform 501, and its central plane α is at 30° with the central plane β of the scissor lift platform.
[0030] The lotus root fiber extraction mechanism 502 includes a mounting frame 5021, a turnover motor 5022, a turnover arm 5023, a bearing seat 5024, a bearing 5025, a fiber collecting rod 5026, a deflection arm 5027, a rotation motor 5028, and a support frame 5029.
[0031] The mounting bracket 5021 is welded to the top of the scissor lift platform 501, and a turnover motor 5022 is mounted on it via a motor mounting bracket. The output shaft of the turnover motor 5022 is connected to the turnover arm 5023 via a coupling. The middle section of the wire collecting rod 5026 is mounted on the turnover arm 5023 via a bearing 5025 and a bearing seat 5024. There is a pair of deflection arms 5027, one of which is equipped with a self-rotating motor 5028, the output shaft of which is connected to one end of the wire collecting rod 5026, and the other deflection arm 5027 is connected to the other end of the wire collecting rod 5026. There is a pair of support brackets 5029, which are symmetrically installed on the top of the scissor lift platform 501 by welding and are respectively connected to the two deflection arms 5027.
[0032] The lotus root fiber extraction mechanism 502 drives the rotating arm 5023 through the rotating motor 5022, so that the fiber collecting rod 5026 realizes the hourglass-shaped spatial trajectory around the central axis a. At the same time, the self-rotating motor 5028 drives the fiber collecting rod 5026 to rotate. The burr-containing part of the fiber collecting rod 5026 is the working end, which can collect the lotus root fibers in the burr part as the fiber collecting rod 5026 rotates and rotates.
[0033] The beneficial effects of this invention are:
[0034] 1. The feeding unit in this invention is designed to fill multiple lotus root stalks at once and feed them in an orderly manner, reducing reliance on manual labor and achieving a high degree of automation. The dual-channel lotus root stalk conveying unit can also improve the efficiency of the device in extracting fibers.
[0035] 2. The design of the cleaning tank and temperature controller in this invention can reduce dirt and bacteria on the lotus root stems, replenish the moisture of the lotus root stems, and control the temperature and humidity within a suitable range can activate the elasticity of the lignocellulose in the lotus root fibers, avoiding the problem of poor fiber drawing caused by dehydration of the lotus root stems.
[0036] 3. The design of the flared elastic lever in this invention has good compatibility with lotus root clamps of different thicknesses and cylindricity;
[0037] 4. In this invention, the collecting rod can achieve simultaneous hourglass-shaped spatial trajectory rotation and self-rotation. Its complex winding trajectory can effectively improve the extraction speed of lotus root fibers. The burr design on the collecting rod can prevent lotus root fibers from falling off, thereby increasing the lotus root fiber collection rate. Attached Figure Description

[0061] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0062] Example 1: As Figure 1-12 As shown, a dual-channel automatic lotus root fiber extraction device consists of five parts: frame 1, feeding unit 2, lotus root stem conveying unit 3, lotus root stem fiber extraction unit 4, and lotus root fiber collection unit 5.
[0063] The frame 1 provides support for the entire equipment. The feeding unit 2 is fixedly installed on the top mounting frame 103, serving as the starting point for equipment operation and providing lotus root raw materials. Two sets of lotus root conveying units 3 are symmetrically installed on the side mounting frames 102, conveying the lotus root provided by the feeding unit 2 at a preset speed and providing clamping and limiting functions at one end of the lotus root. Two sets of lotus root silk-drawing units 4 are symmetrically arranged on the base 101, cooperating with the lotus root conveying units 3 to clamp the lotus root and perform rotary cutting and silk-drawing processing. Two sets of lotus root silk-collecting units 5 are symmetrically arranged on the base between the lotus root conveying units 3 and the lotus root silk-drawing units 4, collecting the exposed lotus root silk extracted from the lotus root. Through the cooperation of these five units, the lotus root silk is finally collected on the silk-collecting rod 5026, which is then removed by the user.
[0064] Furthermore, the frame 1 includes a base 101, side mounting brackets 102, top mounting brackets 103, a control console 104, and a vision sensor 105; the base 101 is located at the bottom of the device; the side mounting brackets 102 are disposed on the left and right sides of the base; the top mounting brackets 103 are disposed on the top of the device; the control console 104 is disposed on the top mounting bracket and controls the operation of the device; the sensor 105 is disposed on the side mounting brackets 102 and is used to monitor the position of the lotus root stalks.
[0065] Furthermore, the feeding unit 2 includes a feeding bin 201, an upper electric conveyor belt 202, a lower electric conveyor belt 203, an air pump cleaner 204, and a temperature controller 205.
[0066] The feeding bin 201 is welded to the top mounting frame 103 and is divided into upper and lower layers. It is equipped with a lotus root inlet A located on the top left side of the feeding bin 201. The upper left side of the feeding bin 201 is a cleaning pool filled with a suitable depth of cleaning liquid. A pair of air inlets D are located on the upper left side of the feeding bin 201. The air pump cleaners 204 are a pair and are set on the left outer shell of the feeding bin 201, connected to the air inlets D. The upper electric conveyor belt 202 is placed at an angle in the cleaning pool, and its inclined top is connected to the diversion port B. The diversion port B is located in the middle of the upper layer of the feeding bin 201. The lower electric conveyor belts 203 are a pair and are symmetrically placed on the left and right sides of the lower layer of the feeding bin 201, respectively connected to a pair of discharge ports C located on the left and right sides of the bottom of the lower layer of the feeding bin 201.
[0067] After a suitable amount of lotus root stems are fed into the lotus root stem inlet A, the stems fall into the washing tank. The temperature controller 205 adjusts the temperature of the washing solution to a suitable level, replenishes the moisture in the lotus root stems, and activates the elasticity of the lignocellulose in the lotus root fibers. Then, the air pump cleaner 204 sprays air from the air inlet D, causing the lotus root stems to tumble in the washing tank to complete the cleaning. At the same time, the air agitates the water flow and sends the lotus root stems into the upper electric conveyor belt 202, which automatically pushes the lotus root stems in an orderly manner to the diversion port B. After falling from the diversion port B, the lotus root stems randomly enter the lower two sides of the feeding bin 201 and are transported to the discharge port C by the lower electric conveyor belt 203.
[0068] Furthermore, the lotus root conveying unit 3 includes a conveyor belt mounting base 301, a motor 302, a drive shaft 303, a drive wheel 304, a belt 305, a lotus root conveying groove 306, a driven wheel 307, a driven shaft 308, and a clamping and limiting mechanism 309.
[0069] The conveyor belt mounting bases 301 are a pair, symmetrically welded to the inner side mounting bracket 102; the motor 302 is mounted on the outer side mounting bracket 102 via a motor mounting bracket, and the motor 302 is connected to the drive shaft 303 via a coupling, driving the drive shaft 303 to rotate; the drive wheels 304 are a pair, keyed and assembled on the drive shaft 303, and form a belt drive with the driven wheel 307 via a belt 305; the driven wheel 307 is keyed and mounted on the driven shaft 308; the lotus root conveying trough 306 is bolted to the conveyor belt mounting base 301, blocking the lotus roots conveyed on the belt 305, providing lateral constraint. When the lotus roots fall from the discharge port C into the lotus root conveying trough 306, the belt 305 drives the lotus roots forward;
[0070] The clamping and limiting mechanism 309 is located at the end of the lotus root conveying groove 306 and includes a hinge support 3091, a fixed limiting post 3092, a movable limiting post 3093, a movable roller 3094, a connecting rod 3095, a gear and rack 3096, and a motor 3097.
[0071] The hinge support 3091 is a pair of hinge bases spaced 35mm apart, which are welded onto the top mounting bracket 103. The fixed limiting post 3092 is connected to one side of the hinge support 3091 via a hinge and is fixedly installed. The movable limiting post 3093 is connected to the other side of the hinge support 3091 via a hinge. Unlike the fixed limiting post 3092, the rod of the movable limiting post 3093 is connected to the gear rack 3096 via a connecting rod 3095 and is powered by a motor 3097. This allows control of the opening and closing action of the rod of the movable limiting post 3093, which is better adapted to the clamping of lotus root stalks of different thicknesses.
[0072] Both the fixed limiting post 3092 and the movable limiting post 3093 are equipped with movable rollers 3094 at their bottom ends, facilitating the conveying of lotus root stalks by compression and rolling. Initially, the motor 3097 is in a normally closed state, and the belt 305 can drive the lotus root stalks to pass smoothly through the clamping and limiting mechanism 309. When the vision sensor 105 observes that the front end of the lotus root stalk is clamped by the lotus root stalk drawing unit 4, the motor 3097 runs, driving the gear rack 3096 to work. The movable gear rack 3096 pushes the movable limiting post 3093 through the connecting rod 3095, completing the clamping of the lotus root stalk together with the fixed limiting post 3092. After a section of lotus root fibers is collected, the motor 3097 returns to a normally closed state, and the lotus root stalk can pass normally, thus completing the cycle.
[0073] Furthermore, the lotus root stalk extraction unit 4 includes a linear movement module 401, a mounting column 402, a fixed shaft 403, a cutting module 404, a crank-slider module 405, and a waste processing module 406.
[0074] The linear movement module 401 is mounted on the base 101, and its linear movement direction is on the same straight line as the lotus root feed direction;
[0075] The mounting post 402 is mounted on the linear module 401 by bolts;
[0076] The fixed shaft 403 is fitted onto the mounting post 402. The main shaft 4031 has an L-shaped air hole E inside, and two elastic paddles 4032 are symmetrically distributed at its end. The two elastic paddles 4032 form a hand-held, trumpet-shaped structure, which facilitates the insertion and centering of the lotus root stem, reduces the requirement for the cylindricality of the lotus root stem, and has micro barbs on its inner side and air holes for easy cleaning.
[0077] The cutting module 404 includes a motor 4041, a bearing seat 4042, a pinion 4043, a gear 4044, an annular guide groove 4045, a front tool mounting seat 4046, a rear tool mounting seat 4047, a tool arm 4048, and a tool 4049.
[0078] The motor 4041 is bolted to the top of the mounting column 402. Its output shaft is connected to the pinion 4043 via a bearing seat 4042, driving the pinion 4043 to rotate. The pinion 4043 meshes with the large gear 4044. The large gear 4044 is mounted on the fixed shaft 403 with a clearance fit. Four solid steel bars are welded to its end face. The solid steel bars pass through four small holes evenly distributed along the circumference on the front mounting base 4046 of the tool and are welded to the rear mounting base 4047 of the tool. The annular guide groove 4045 is welded to the front mounting base 4046 of the tool, and a three-quarter spherical guide groove is opened on its circumference. The tool arm 4048 is bolted to the front mounting base 4046 of the tool and the tool 4049. The tail of the tool 4049 is bolted to the rear mounting base 4047 of the tool. The cutting angle of the tool 4049 can be adjusted with the linear movement of the annular guide groove 4045.
[0079] The small gear 4043 meshes with the large gear 4044 to drive the entire cutting module 404 to rotate, and works with the cutter 4049 to complete the circumferential cutting function. The tooth thickness of the small gear 4043 is significantly thicker than that of the large gear 4044, so that the large gear 4044 has linear movement space.
[0080] The crank-slider module 405 includes a motor 4051, a bearing housing 4052, a pinion 4053, a large gear 4054, a connecting rod 4055, and a spherical slider 4056. The motor 4051 is bolted to the mounting post 402, and its output shaft is connected to the pinion 4053 through the bearing housing 4052. The pinion 4053 meshes with the large gear 4054 for transmission. The large gear 4054 is connected to the spherical slider 4056 through the connecting rod 4055 and transmits power to the spherical slider 4056. The spherical slider 4056 is fitted into an annular guide groove 4045 and is constrained by a three-quarter spherical guide rail groove on the annular guide groove 4045. The spherical slider 4056 can drive the annular guide groove 4045 to achieve reciprocating linear motion without hindering the rotational motion of the cutting module 404.
[0081] The waste processing module 406 is arranged on the side of the mounting column 402 and includes an air pump 4061 and a conduit 4062. One end of the conduit 4062 is connected to the air pump 4061, and the other end is inserted into the air hole left on the mounting column 402. The air hole of the mounting column 402 is connected to the L-shaped air hole E in the fixed shaft 403, so that the high-pressure gas generated by the air pump 4061 can flush the lotus root residue in the fixed shaft 403.
[0082] When the lotus root stalk is conveyed to the elastic lever 4032 at the front end of the fixed shaft 403 by the lotus root stalk conveying unit 3, the hand-held, trumpet-shaped elastic lever 4032 guides the lotus root stalk to center and enter, and the barbs on it prevent the lotus root stalk from sliding out. At the same time, the crank slider module 405 can drive the annular guide groove 4045 and the front mounting seat of the cutter 4046 to squeeze the rear mounting seat of the cutter 4047 together, so that the rear mounting seat of the cutter 4047 pushes forward to squeeze the elastic lever 4032 at the front end of the fixed shaft 403 and deforms and tightens it, thus clamping the lotus root stalk. Then the cutting module 404 rotates so that the cutter 4049 makes an annular cut on the surface of the lotus root stalk to an appropriate depth. After that, the linear movement module 401 moves backward, so that the lotus root stalk that has been annularly cut is broken off, exposing the lotus root fibers. After the lotus root collecting unit 5 has collected the lotus root fibers, the crank slider module 405 drives the annular guide groove 4045 and the front mounting seat of the cutter 4046 to leave the rear mounting seat of the cutter 4047. After the rear mounting seat of the cutter 4047 is no longer under force, it slides back naturally, causing the elastic paddle 4032 to relax and the lotus root waste to be loosened. At this time, the waste processing module 406 sprays air to blow out the lotus root waste, waiting for new lotus root to be filled in.
[0083] Furthermore, the lotus root fiber collecting unit 5 includes a scissor-type lifting platform 501 and a lotus root fiber extraction mechanism 502;
[0084] The scissor lift platforms 501 are a pair, set on the base 101, and can move up and down; the lotus root silk extraction mechanism 502 is welded to the scissor lift platform 501, and its central plane α is at 30° with the central plane β of the scissor lift platform.
[0085] The lotus root fiber extraction mechanism 502 includes a mounting frame 5021, a turnover motor 5022, a turnover arm 5023, a bearing seat 5024, a bearing 5025, a fiber collecting rod 5026, a deflection arm 5027, a rotation motor 5028, and a support frame 5029.
[0086] The mounting bracket 5021 is welded to the top of the scissor lift platform 501, and a turnover motor 5022 is mounted on it via a motor mounting bracket. The output shaft of the turnover motor 5022 is connected to the turnover arm 5023 via a coupling. The middle section of the wire collecting rod 5026 is mounted on the turnover arm 5023 via a bearing 5025 and a bearing seat 5024. There is a pair of deflection arms 5027, one of which is equipped with a self-rotating motor 5028, the output shaft of which is connected to one end of the wire collecting rod 5026, and the other deflection arm 5027 is connected to the other end of the wire collecting rod 5026. There is a pair of support brackets 5029, which are symmetrically installed on the top of the scissor lift platform 501 by welding and are respectively connected to the two deflection arms 5027.
[0087] The lotus root fiber extraction mechanism 502 drives the rotating arm 5023 through the rotating motor 5022, so that the fiber collecting rod 5026 can rotate around the central axis a in an hourglass-shaped spatial trajectory. At the same time, the self-rotating motor 5028 drives the fiber collecting rod 5026 to rotate. The burred part of the fiber collecting rod 5026 is the working end, which can collect the lotus root fibers in the burred part as the fiber collecting rod 5026 rotates and rotates.
[0088] The scissor lifting platform 501 is in a stationary state when it is lowered. When the lotus root stalk exposes the lotus root fibers through the lotus root stalk extraction unit 4, the scissor lifting platform 501 rises, and the lotus root fiber extraction mechanism 502 works to collect the exposed lotus root fibers. When a section of lotus root fibers has been collected, the scissor lifting platform 501 falls, and this cycle repeats.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
