Description

Technical Field

[0001] The present application relates to agricultural machinery and equipment, belonging to the technical field of waste ground film recovery, and specifically to a film residue separation device. Background Art

[0002] The main component of mulch film is polyethylene, which is a high molecular compound and is difficult to degrade under natural conditions. If waste mulch film is not recycled in time and abandoned on the edge of the field, it will not only cause environmental pollution and stay in the cultivated land for a long time, but also destroy the soil structure, reduce soil moisture absorption and permeability, thereby reducing soil fertility, affecting crop emergence, and leading to reduced production. my country is a large agricultural country, and mulch film is widely used. With the large-scale application of mulch film covering technology, problems are becoming increasingly apparent: waste mulch film is difficult to recycle and the reuse rate is low. 74% of the global mulch film usage is in China, and the recycling and reuse of waste mulch film needs to be solved urgently. The application of new machinery and new technologies for agricultural residual film has provided a basis for the recycling of agricultural residual film and increased the enthusiasm of farmers to recycle waste film. However, due to the limitations of recycling technology and mechanical equipment, the recycled mulch film contains a large amount of debris such as soil, stone, crop straw, etc., and the proportion of waste mulch film is less than 10%, resulting in the recycling of the recycled waste mulch film cannot be further recycled.

[0003] At present, the existing mixed waste mulch film separation equipment mainly adopts multi-stage drum screens and multi-stage wind selection methods, which have the problems of low sorting efficiency, high energy consumption and high cost, thereby limiting the ability to process and recycle waste mulch films on a large scale, resulting in insufficient enthusiasm of farmers to recycle waste mulch films and inability to promote it; the waste mulch film mixture recovered from cotton fields will contain fallen cotton (after the cotton pickers pick the cotton, the unblooming cotton and the unpicked cotton are all discarded in the field as fallen cotton), which can also be recycled and reused, while the existing separation equipment only aims to obtain waste mulch films. After separation, the cotton is directly discarded together with other impurities, which will cause cotton waste, or a large amount of cotton will remain in the waste mulch films obtained after separation, resulting in a decrease in the recycling and reuse rate of waste mulch films. Summary of the invention

[0004] Purpose of the invention: This application aims to overcome the defects of the prior art and provide a membrane slag separation device.

[0005] Technical solution: A film-residue separation device comprises a box body, a material transfer unit and a sorting unit, wherein the box body has a material feed port, the material transfer unit comprises a conveying part, a driving unit for driving the conveying part for circular conveying, and a plurality of separation rods that can move with the conveying part; the sorting unit comprises a blowing unit, and the wind blown out by the blowing unit can pass through the conveying part and blow the separation rods.

[0006] Furthermore, the conveying part includes an upper rotating shaft, a lower rotating shaft, two upper rotating wheels installed at the upper rotating shaft, and two lower rotating wheels installed at the lower rotating shaft. The two upper rotating wheels and the two lower rotating wheels correspond to each other one by one. A transmission unit is installed between the corresponding upper rotating wheels and the lower rotating wheels, and a connecting part is connected between the two transmission units; the driving unit is used to drive the upper rotating shaft or the lower rotating shaft to rotate.

[0007] Thus, the driving unit drives the upper rotating wheel or the lower rotating wheel to rotate, and drives the corresponding rotating wheel to rotate through the transmission unit.

[0008] Furthermore, a plurality of strip-shaped fixing plates are connected between the two transmission units, and a plurality of the separation rods are disposed at each strip-shaped fixing plate.

[0009] As a result, the material enters the box and falls on the separation rod, and the separation rod is used to hang the material.

[0010] Furthermore, the separation rod is L-shaped.

[0011] Thus, one end of the separation rod is fixed to the strip-shaped fixing plate. Thus, the strip-shaped air outlet can better blow air to the material hung on the L-shaped separation rod.

[0012] Furthermore, the upper rotating wheel and the lower rotating wheel are both synchronous wheels, and the transmission unit is a synchronous belt.

[0013] The long-distance transmission of synchronous wheels is more stable, efficient and has good energy-saving effects.

[0014] In other embodiments, the upper rotating wheel and the lower rotating wheel are both sprockets, and the transmission unit is a chain.

[0015] The sprocket has a stronger carrying capacity and better strength.

[0016] Furthermore, the driving unit is a reduction motor connected to the upper rotating shaft or the lower rotating shaft through a coupling.

[0017] It is used to drive the upper shaft or the lower shaft to rotate well.

[0018] Furthermore, the upper rotating shaft and the lower rotating shaft are both provided with a plurality of guide rollers.

[0019] Thereby the connection part is better supported, thereby driving the connection part to move cyclically better.

[0020] Furthermore, the connecting portion is a metal mesh woven from metal, and two sides of the metal mesh are respectively connected to the two transmission units.

[0021] The metal mesh has better ventilation and better toughness.

[0022] In other embodiments, the connecting portion is a circle of chain plates, and the chain plates have ventilation holes.

[0023] Furthermore, a circle of chain plates includes a plurality of chain plates distributed in a circle, and any two adjacent chain plates are hinged.

[0024] The chain plate is high in strength and not easy to wear.

[0025] Furthermore, the blowing unit includes a fan and a bellows, the bellows is surrounded by the connecting portion and installed at the bottom end of the internal space of the connecting portion, the top and bottom ends of the bellows are both closed, and the side of the bellows has a plurality of strip-shaped air outlets.

[0026] Therefore, the ground film and cotton on the separation rod rotating through this area are blown out through the strip air outlet.

[0027] Furthermore, the sorting unit also includes a sorting bin connected to the box body, and the wind blown out of the strip-shaped air outlet blows toward the sorting bin.

[0028] Therefore, the wind from the strip air outlet blows the ground film and cotton horizontally. Utilizing the density properties of the ground film and cotton, the ground film and cotton fall successively into the sorting bin along the parabolic direction under the action of the horizontal wind speed, thereby further separating the ground film and the cotton, and the ground film is separated and recovered from the sorting bin.

[0029] Furthermore, the box body includes a front panel, a back panel and two opposite side panels, the front panel and the back panel are opposite to each other, the feed port is located at the front panel, and the sorting bin is connected to the back panel.

[0030] Furthermore, the bottom of the box body has a first feed opening and a second feed opening, the first feed opening is located between the panel and the connecting portion, and the second feed opening is located between the back panel and the connecting portion.

[0031] Therefore, the small pieces of cotton, small pieces of straw and soil mixture at the first feeding port can be further separated into cotton and straw by a cotton cleaner; the large pieces of cotton and large pieces of straw mixture at the second feeding port can be further separated into cotton and straw by a cotton cleaner, so that the cotton can be separated and recovered more conveniently.

[0032] Furthermore, the back plate has a sorting discharge port connected to the sorting bin.

[0033] Therefore, the mulch film and cotton can be blown by the wind from the bellows to the sorting bin for sorting.

[0034] Furthermore, it also includes a dust removal unit, which includes a dust removal plate with multiple dust removal holes. The space between the dust removal plate and the box body forms a dust removal space. The top of the box body is equipped with a top induced draft fan capable of exhausting air from the dust removal space.

[0035] Therefore, during the separation process, the dust in the material enters the dust removal space through the dust removal holes on the dust removal plate, and the induced draft fan at the top of the box body sucks away the dust inside the dust removal space, so that the separated ground film and cotton are purer.

[0036] Furthermore, the box body includes a panel, a back panel and two opposite side panels, the panel and the back panel are opposite, the feed port is located at the panel, and the dust removal plate includes a front dust removal plate located between the panel and the connecting part and a back dust removal plate located between the back panel and the connecting part; the front dust removal plate and the back dust removal plate both have the dust removal holes.

[0037] Therefore, the dust removal space between the dust removal plate and the box body is connected up and down to form a whole, so that the induced draft fan at the top of the box body can be used to suck away the dust inside the upper and lower dust removal spaces.

[0038] Furthermore, the front dust removal plate has an opening facing the feed port.

[0039] Furthermore, a rectangular frame-shaped connecting frame is connected between the front dust removal plate and the panel.

[0040] Furthermore, the opening is surrounded by the connection frame.

[0041] Therefore, the connection frame can prevent the material from falling between the panel and the front dust removal plate, that is, prevent the material from falling into the dust removal space.

[0042] Furthermore, the diameter of the dust removal hole is 2-5 mm.

[0043] Therefore, during the conveying process, tiny dust in the material can enter the dust removal space through the dust removal plate.

[0044] Furthermore, an elastic material unit is installed in the box body, and the elastic material unit can be touched by the end of the separation rod and allow the separation rod to pass through.

[0045] Therefore, when the conveying part conveys the material upward, the separation rod passes through the elastic unit and its end touches the elastic unit, so that the separation rod vibrates, thereby breaking up the material on the separation rod and dispersing the material, so that the straw, soil and cotton impurities can fall vertically.

[0046] Furthermore, there are a plurality of the elastic material units, and the plurality of elastic material units are divided into multiple layers, and each layer has two of the elastic material units.

[0047] Thereby, the separation rod can be vibrated multiple times to break up the materials multiple times.

[0048] Furthermore, the elastic material unit includes a rotating shaft and a rotating roller installed on the rotating shaft.

[0049] After the end of the separation rod touches the elastic unit and completes the vibration, the elastic unit can rotate to allow the separation rod to pass, thereby continuing to convey the material. The elastic device does not require power. When the separation rod touches the rotating roller, the separation rod is compressed and slightly bends downward. Since the rotating roller can rotate under the friction of the separation rod, the separation rod can continue to move upward, and after separating from the rotating roller, it rebounds upward, thereby achieving the purpose of elasticity, so that the separation rod vibrates, thereby better separating the material.

[0050] Furthermore, the elastic device is installed in the box through a mounting frame.

[0051] Furthermore, the dust removal plate has a groove portion, and the groove portion is used to install the elastic material unit.

[0052] Furthermore, there are a plurality of groove portions.

[0053] Furthermore, a plurality of groove portions are located on the front dust removal plate.

[0054] Therefore, a groove portion is arranged at the dust removal plate to provide space for installing the elastic material unit, thereby making the structure of the device more compact.

[0055] Furthermore, the strip-shaped fixing plate is a U-shaped groove plate.

[0056] Thereby, the end of the L-shaped separation rod can be inserted into the U-shaped groove of the U-shaped groove plate and fixed.

[0057] Furthermore, two ends of the fixing plate are fixed to two chains respectively.

[0058] Thereby, the chain can drive the fixed plate to move synchronously and transport materials.

[0059] In other embodiments, two ends of the fixed plate are respectively fixed to two synchronous belts.

[0060] Therefore, the synchronous belt can drive the fixed plate to move synchronously and transport materials.

[0061] Furthermore, the wind box has 5-10 strip-shaped air outlets.

[0062] Furthermore, the strip-shaped air outlet can discharge air horizontally.

[0063] Thereby, the mulch film and cotton on the separation rod can be blown out from the horizontal direction and fall in a parabolic direction for further sorting.

[0064] Furthermore, the strip-shaped air outlet is rectangular, and the width of the strip-shaped air outlet is 1-10 mm, preferably 1 mm.

[0065] Therefore, the outlet wind speed is higher, and the materials hanging on the mulch film separation rod can be quickly blown down horizontally, so as to achieve the purpose of stripping the materials from the mulch film separation rod, and the horizontal wind speed can be used to separate the mulch film and cotton.

[0066] Furthermore, among the multiple separation rods at the same strip-shaped fixing plate, the interval between any two adjacent separation rods is between 100-500 mm.

[0067] Furthermore, the plurality of separation rods at the same strip-shaped fixing plate are evenly spaced and spaced 100-500 mm apart.

[0068] Therefore, when the separation rod transports materials upward, large pieces of straw, large pieces of cotton, and mulch are caught and moved to the opposite side with the separation rod, while small pieces of straw, soil, small pieces of cotton and other impurities cannot be caught and fall vertically.

[0069] Furthermore, the box body is placed vertically; the front panel, back panel and two side panels are all vertical panels.

[0070] Furthermore, the plurality of strip-shaped fixing plates are distributed at equal intervals along the transmission direction of the transmission unit.

[0071] Furthermore, two adjacent strip-shaped fixing plates are spaced 100-300 mm apart along the transmission direction of the transmission unit.

[0072] From top to bottom, the separation rods at different heights are staggered horizontally, so that the ground film that falls from the upper part can be caught in time by the separation rods at the appropriate level below, instead of falling directly into the bottom discharge port.

[0073] Beneficial effects: 1) The driving unit drives the conveying part to circulate and convey materials in the vertical direction, and the size difference, hardness and specific gravity of the materials are utilized, so that the mulch film, large pieces of straw and large pieces of cotton are hung on the separation rod, and small pieces of straw, soil and small pieces of cotton fall vertically, thereby realizing primary separation; the mulch film, large pieces of cotton and large pieces of straw are transferred to the opposite side of the feed port, and as the separation rod turns over, the large pieces of cotton and large pieces of straw fall vertically due to gravity and fall to the second feed port, thereby realizing secondary separation; thus, the sorting efficiency is high, the energy consumption is low and the cost is low;

[0074] 2) By setting up a sorting unit, the mulch film and cotton hung on the separation rod are blown out in the horizontal direction by a bellows, and the density of the mulch film and cotton is used to make the mulch film and cotton fall successively along the parabola direction under the action of the horizontal wind speed, so as to further separate the mulch film and cotton impurities, thereby achieving three separations with higher separation efficiency, thereby improving the recycling rate of waste mulch film;

[0075] 3) By arranging the first feeding port and the second feeding port at the bottom of the box body, the small pieces of cotton, small pieces of straw and soil mixture at the first feeding port can be further separated into cotton and straw by a cotton cleaning machine; the large pieces of cotton and large pieces of straw mixture at the second feeding port can be further separated into cotton and straw by a cotton cleaning machine, so that the waste mulch can be separated and recycled more conveniently at the same time, thereby reducing cotton waste;

[0076] 4) By providing a material-elasticating unit, when the conveying part conveys the material upward, the separation rod passes through the material-elasticating unit, and its end touches the material-elasticating unit, so that the separation rod vibrates, thereby breaking up the material on the separation rod, dispersing the material, and facilitating the vertical fall of straw, soil and cotton impurities;

[0077] 5) By setting up a dust removal unit, during the separation process, the dust in the material enters the dust removal space through the dust removal holes on the dust removal plate, and the induced draft fan at the top of the box is used to suck away the dust inside the dust removal space, so that the separated mulch and cotton are purer.

The ejector unit 6 includes a rotating shaft and a rotating roller installed at the rotating shaft.

[0091] As shown in the figure, the present application is used to separate the film residue from the recycled waste film mixture. Taking a large amount of waste film recycled from Xinjiang cotton fields as an example, after the recycled waste film is cut, it enters the material transfer unit inside the box through the feed port, and the material at the feed port falls on the separation rod of the conveying part. The driving unit drives the rotating shaft to rotate, so that the upper and lower rotating wheels rotate synchronously through the transmission unit, so that the conveying part circulates and transports; in the process of the conveying part conveying the material upward, the separation rod passes through the elastic material unit, and its end touches the elastic material unit, so that the separation rod vibrates, thereby breaking up the material on the separation rod; as the separation rod is moved, the small pieces of straw in it are The stalks, soil and small pieces of cotton fall freely. During the falling process, since the separation rods are arranged at non-equidistant intervals, the separation rods at different heights are staggered horizontally from top to bottom, so the ground film falling from the upper part can be caught in time by the separation rods at the appropriate level below, instead of falling directly into the bottom discharge port directly below.

[0092] The conveying part continues to drive the separation rod to move, and transfers the ground film, large pieces of cotton, and large pieces of straw to the opposite side of the feed port. The material on the separation rod flips with the separation rod, and large pieces of cotton and large pieces of straw fall vertically due to gravity and fall to the second feed port. The ground film and a small amount of cotton continue to be hung on the separation rod to achieve secondary separation; the remaining material passes through the bellows position of the blowing unit, and the wind from the bellows blows the separation rod through the metal mesh of the conveying part, thereby blowing the ground film and a small amount of cotton hanging on the separation rod horizontally. Due to the different densities of the ground film and cotton, the ground film and cotton fall successively along the parabolic direction under the action of the horizontal wind speed, thereby achieving three separations and obtaining pure ground film and cotton.

[0093] In addition, in the first separation, the small pieces of cotton, small pieces of straw and soil mixture from the first feeding port can be further separated into cotton and straw by a cotton cleaner; in the second separation, the large pieces of cotton and large pieces of straw mixture from the second feeding port can be further separated into cotton and straw by a cotton cleaner, thereby effectively recovering cotton while separating waste mulch and reducing cotton waste.
