Description

Technical Field

[0001] The present application relates to the field of straw processing, and in particular to a straw breaking and stem-leaf separating device. Background Art

[0002] The straws of crops such as corn are biomass materials with a huge output, and have extremely high utilization value in various fields such as agriculture, animal husbandry, planting, and papermaking; in addition, in recent years, the hard fibers in straws have been widely used in precast wall panels. The lightweight wall panels made of plant fibers such as straws are lightweight, durable, heat-insulating, waterproof, environmentally friendly and non-toxic, and largely meet the current demand for low energy consumption in buildings.

[0003] When using straw fibers to make building materials such as wall panels, due to the relatively fixed shape of straws, and the fiber hardness of the stems and leaves, as well as the shells and cores of the stems being different, during the process of making wall panels and other recycling processes, it is generally necessary to first separate the stems from the stems and leaves, and then break the stems to screen out the required fiber materials, which are then used as one of the raw materials for building materials such as wall panels.

[0004] In view of the above related technologies, currently, when harvesting straws, they are generally baled with stems and leaves and stored. Due to the mutual extrusion between straws, the stems and leaves are attached to the stems, making it difficult to separate the stems and leaves, which in turn affects the overall processing efficiency. Summary of the Invention

[0005] In order to improve the processing efficiency, the present application provides a straw breaking and stem-leaf separating device.

[0006] The present application provides a straw breaking and stem-leaf separating device, adopting the following technical solution: A straw breaking and stem-leaf separating device includes a feeding bin, and an opening for straws to enter is provided at the upper end of the feeding bin; a separating and conveying bin, located on one side of the feeding bin, with openings at both ends in the length direction of the separating and conveying bin, and one end is set as the feeding end and the other end is set as the discharging end, and the feeding end is communicated with one side of the feeding bin; a plurality of feeding rollers, the feeding rollers are parallel to each other, and a plurality of feeding rollers are horizontally rotatably connected in the feeding bin and are arranged along the direction close to the separating and conveying bin for conveying the straws into the separating and conveying bin; a plurality of conveying rollers, the conveying rollers are parallel to each other, and a plurality of conveying rollers are horizontally rotatably connected in the separating and conveying bin and are arranged along the length direction of the separating and conveying bin for conveying the straws to the discharging end, the height of the conveying rollers is equal to or lower than the height of the feeding rollers, the surface of the conveying rollers is provided with patterns, and a driving member for driving the conveying rollers and the feeding rollers to rotate is provided in the separating and conveying bin; a tearing and breaking machine, located on one side of the separating and conveying bin, for breaking the stems, and the tearing and breaking machine is provided with a feeding port and a discharging port, and the feeding port is communicated with the discharging end of the separating and conveying bin.

[0007] By adopting the above technical scheme, the feed roller and the conveying roller both rotate under the action of the driving member. After the straw is unbundled, it enters the feed bin and falls on the feed roller for distribution. At this time, the adjacent straws are dispersed and are conveyed by the feed roller to the conveying roller in the separation and conveying bin. While the conveying roller is conveying the straw, the stems and leaves of the straw will extend between the adjacent conveying rollers. Since the texture on the surface of the conveying roller has a large friction force on the straw, the stems and leaves of the straw are torn off by the conveying roller during the movement of the straw, thereby realizing the separation of the stems and leaves from the stems, and the stems and leaves fall under the separation and conveying bin. The stems enter the tearing and wall breaking machine from the discharge end of the separation and conveying bin for crushing. The required fiber material can be quickly obtained by directly putting in the bundles of straw, with high processing efficiency.

[0008] Optionally, the conveying rollers are all inclined, and the angle between the conveying rollers and the width direction of the separation conveying bin is set to a, and 0° <a<90°。

[0009] By adopting the above technical solution, a certain angle is formed between the inclined conveying roller and the straw moving side by side, and the straw is not easily stuck between adjacent conveying rollers, which is beneficial to improving the conveying effect of the conveying roller on the straw. At the same time, since the conveying roller is inclined, the pulling force of the conveying roller on the stems and leaves is also inclined, making the stems and leaves easier to separate from the stems, and the structure is simple and the effect is effectively improved.

[0010] Optionally, it also includes: a stem and leaf conveyor belt, located in the separation and conveying bin and below the feeding roller, the stem and leaf conveyor belt is arranged along the length direction of the separation and conveying bin and is used to receive the stems and leaves; a stem and leaf baler, located at the conveying end of the stem conveyor belt and is used to bundle the stems and leaves.

[0011] By adopting the above technical solution, the equipment keeps running, and the stems and leaves keep falling under the separation and conveying bin. The stem and leaf conveyor belt receives the fallen stems and leaves, and transports them to the stem and leaf baler for automatic baling and discharge. This is beneficial to the continuous operation of the equipment and does not easily affect the processing efficiency due to the cleaning of the stems and leaves.

[0012] Optionally, it also includes: a finished product conveying bin, located on one side of the tearing and wall breaking machine, with both ends of the finished product conveying bin being open in the length direction, and one end being connected to the discharge port of the tearing and wall breaking machine; a finished product conveyor belt, located in the finished product conveying bin and arranged along the length direction of the finished product conveying bin, for conveying the finished products from one end of the finished product conveying bin to the other end.

[0013] By adopting the above technical solution, the straw is crushed and moved in the finished product conveying bin under the conveying action of the finished product conveying belt. The user can connect the finished product conveying bin with the warehouse or conveying line, thereby facilitating the direct transportation or storage of the finished products.

[0014] Optionally, it further includes: a dust collector, which is communicated with one end of the finished product conveying bin close to the tearing and breaking machine; a spray pipe, which is located inside the other end of the finished product conveying bin away from the tearing and breaking machine and above the finished product conveyor belt.

[0015] By adopting the above technical solution, after the straw is crushed, in addition to the required hard fiber materials, there are also impurities such as dust. During the movement along the finished product conveyor belt, this part of the impurities is sucked into the dust collector and discharged with the air, and the spraying of the spray pipe is coordinated to reduce the dust caused by air flow.

[0016] Optionally, the driving member includes a chain, a plurality of first sprockets corresponding to the conveying rollers one by one, and second sprockets corresponding to the feeding rollers one by one. The first sprockets and the second sprockets are both engaged with the chain. The first sprockets are coaxially and fixedly connected with transmission shafts, and the transmission shafts are rotatably connected to the separation and conveying bin and are arranged along the width direction of the separation and conveying bin. A universal joint is connected between the conveying rollers and the corresponding transmission shafts.

[0017] By adopting the above technical solution, under the action of the chain, the first sprockets and the second sprockets rotate synchronously. The first sprockets drive the feeding rollers to rotate, and the second sprockets drive the inclined conveying rollers to rotate through the transmission shafts and the universal joints. The structure is simple and the cost is low, and it has the effect of convenient control.

[0018] Optionally, a vibrating plate is arranged in the feeding bin. The vibrating plate is inclined, and there is a feeding gap for the straw to pass through between the lower end surface of the vibrating plate and the inner wall of the feeding bin at the lower end with a lower height. A vibrating motor is arranged on the lower end surface of the vibrating plate.

[0019] By adopting the above technical solution, the baled straw falls on the vibrating plate. Under the vibration of the vibrating motor, the vibrating plate vibrates the straw, and then quickly disperses the adjacent straws, ensuring that when the straw moves on the conveying rollers, it can fully contact the conveying rollers, and further ensuring the separation effect between the leaves and the stems.

[0020] Optionally, there are two vibrating plates. The two vibrating plates are symmetrical to each other, and the lower ends with lower heights are close to each other. The feeding gap is located between the lower ends with lower heights of the two vibrating plates.

[0021] By adopting the above technical solution, the two vibrating plates vibrate and disperse the straw at the same time. While improving the dispersion efficiency, the feeding gap can correct the direction of the straw, making the straw close to the width direction of the separation and conveying bin, and cooperating with the feeding rollers to improve the feeding effect of the straw.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The feed roller and the conveying roller rotate under the action of the driving member. After the straw is unbundled, it enters the feed bin and falls on the feed roller for distribution. At this time, the adjacent straws are dispersed and conveyed by the feed roller to the conveying roller in the separation and conveying bin. While the conveying roller is conveying the straw, the stems and leaves of the straw will extend between the adjacent conveying rollers. Since the texture on the surface of the conveying roller has a large friction force on the straw, the stems and leaves of the straw are torn off by the conveying roller during the movement, so that the stems and leaves are separated from the stems. The stems and leaves fall under the separation and conveying bin, and the stems enter the tearing and wall breaking machine from the discharge end of the separation and conveying bin for crushing. The required fiber material can be quickly obtained by directly putting the bundled straw in, which has high processing efficiency. 2. A certain angle is formed between the inclined conveying roller and the straw moving side by side, so the straw is not easily stuck between adjacent conveying rollers, which is beneficial to improving the conveying effect of the conveying roller on the straw. At the same time, due to the inclination of the conveying roller, the pulling force of the conveying roller on the stems and leaves is also inclined, making it easier to separate the stems and leaves from the stems. The structure is simple and the effect is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0029] The embodiment of the present application discloses a device for breaking straw walls and separating stems and leaves.

[0030] Embodiment 1: Reference Figure 1, A straw breaking and stem-leaf separation device, which includes a feeding bin 1, a separation and conveying bin 2, a tearing and breaking machine 3, and a finished product conveying bin 4 installed in sequence. The bundled straw is placed in the conveying bin after being unpacked, dispersed in the conveying bin, and then enters the separation and conveying bin 2. After the separation of the leaves and stems in the separation and conveying bin 2, the stems enter the tearing and breaking machine 3, and the tearing and breaking machine 3 breaks the stems. The broken finished fiber is discharged through the finished product conveying bin 4 for transfer or storage, completing the entire processing process.

[0031] Refer to Figure 1 , The upper end of the feeding bin 1 is open. In this embodiment, the shape of the feeding bin 1 is preferably a rectangular hopper shape that is larger at the top and smaller at the bottom. During operation, the user can use existing grasping equipment such as a grabber to unpack the stored straw and put it into the feeding bin 1 from above. The straw bale falls in the feeding bin 1 due to gravity; several feeding rollers 11 are installed in the feeding bin 1, and the feeding rollers 11 are all horizontally arranged. After the straw bale falls on the feeding rollers 11, it is dispersed for feeding.

[0032] Refer to Figure 1 and Figure 2 , The separation and conveying bin 2 is located on one side of the feeding bin 1 and is connected to the feeding bin 1. The feeding rollers 11 are all arranged along the width direction of the separation and conveying bin 2 and are arranged along the length direction of the separation and conveying bin 2. A driving member 5 for driving the feeding rollers 11 to rotate is installed in the feeding bin 1. Thus, during the rotation of the feeding rollers 11, the adjacent straws are dispersed and conveyed into the separation and conveying bin 2; all the feeding rollers 11 are at the same height, or the feeding rollers 11 closer to the separation and conveying bin 2 are lower in height, as long as it is convenient for the straw to move into the separation and conveying bin 2. In this embodiment, it is preferably that all the feeding rollers 11 are at the same height, and the distance between adjacent feeding rollers 11 is less than the diameter of the straw, so that the straw is not likely to leak under the feeding rollers 11.

[0033] Refer to Figure 2 and and Figure 3 , The driving member 5 includes a chain 51 and several second sprockets 53 corresponding to the feeding rollers 11 one by one. All the second sprockets 53 are simultaneously engaged with the chain 51, and the second sprockets 53 are coaxially and fixedly installed at one end of the corresponding feeding roller 11 in the length direction. A motor (not shown in the figure) is fixedly installed on the side wall of the feeding bin 1, and the output shaft of the motor (not shown in the figure) is coaxially and fixedly connected to one of the feeding rollers 11. Thus, when the motor (not shown in the figure) is started, all the feeding rollers 11 can be driven to rotate synchronously.

[0034] Refer to Figure 1, one end of the separation and conveying bin 2 communicating with the feeding bin 1 is set as the feeding end 21, and the other end is set as the discharging section. The continuous rotation of the feeding roller 11 continuously conveys straw into the feeding end 21. A plurality of conveying rollers 23 are installed in the separation and conveying bin 2. The conveying rollers 23 are all horizontally arranged, that is, both ends in the length direction of the conveying roller 23 are at the same height, and this height is equal to or less than the height of the lowest feeding roller 11, which is convenient for the feeding roller 11 to convey the straw onto the conveying roller 23. In this embodiment, it is preferably that the height of the conveying roller 23 is the same as that of the feeding roller 11.

[0035] Refer to Figure 2 and Figure 3 , the distance between adjacent conveying rollers 23 is less than the diameter of the straw, and the driving member 5 further includes a first sprocket 52 for driving the conveying roller 23 to rotate, and then the rotation of the conveying roller 23 is used to convey the straw to the discharging end 22 of the separation and conveying bin 2. Further, in this embodiment, it is preferably that the conveying roller 23 is inclined in the horizontal plane, that is, the distances between both ends in its length direction and the feeding bin 1 are different, so that the straw is not parallel to the conveying roller 23, and the straw is not easily leaked under the conveying roller 23. The included angle between the conveying roller 23 and the width direction of the separation and conveying bin 2 is set as a, and 0° < a < 90°. Within this range, while ensuring the stable rotation of the conveying roller 23 to convey the straw to the discharging end 22, the pulling ability of the conveying roller 23 on the stems and leaves is improved. In this embodiment, 30° is preferably selected.

[0036] Refer to Figure 3 , the first sprocket 52 is coaxially and fixedly connected with a transmission shaft 521 along the width direction of the separation and conveying bin 2. The transmission shaft 521 is rotatably connected to the separation and conveying bin 2. The number of the first sprockets 52 is the same as that of the conveying rollers 23 and they are in one-to-one correspondence. All the first sprockets 52 are simultaneously engaged with the chain 51. Then, under the action of the chain 51, the first sprocket 52 and the second sprocket 53 rotate synchronously. A universal joint 522 is connected between the transmission shaft 521 and the corresponding conveying roller 23. Since the conveying roller 23 is inclined, the universal joint 522 can maintain the continuous transmission of the first sprocket 52 to the conveying roller 23 and convey the straw to the discharging end 22.

[0037] Refer to Figure 1 , when the straw moves above the conveying roller 23, it will also rotate by itself, and the stems and leaves on it will be inserted between adjacent conveying rollers 23. The surface of the conveying roller 23 is provided with patterns for increasing friction. While the straw is moving, the stems and leaves will be pulled and separated from the stalks; the pulling direction of the stems and leaves by the inclined conveying roller 23 is different from the moving direction of the stalks, so that the separation effect of the stems and leaves and the stalks is better. The separated stems and leaves fall below the conveying roller 23, while the stalks are continuously conveyed by the conveying roller 23 to the discharging end 22.

[0038] Refer to Figure 1, since the work continues, if too much stem and leaf accumulate under the separation and conveying bin 2, it is likely to affect the rotation of the conveying roller 23. A stem and leaf conveyor belt 24 is installed below the conveying roller 23 in the separation and conveying bin 2. The stem and leaf conveyor belt 24 is arranged along the length direction of the separation and conveying bin 2. The stem and leaf fall on the stem and leaf conveyor belt 24 and move towards the conveying end of the stem and leaf conveyor belt 24. The conveying end of the stem and leaf conveyor belt 24 is the end close to the discharge end 22 of the separation and conveying bin 2, and a stem and leaf baler 25 is installed at the conveying end of the stem and leaf conveyor belt 24. Any common baler can be selected for the stem and leaf baler 25, and this embodiment will not elaborate too much; after the stem and leaf are sent into the stem and leaf baler 25 by the stem and leaf conveyor belt 24, they are baled and output, ensuring that there is enough space below the conveying roller 23 to accommodate the stem and leaf.

[0039] Refer to Figure 1 , the tearing and breaking mill 3 is provided with a feed inlet 31, a discharge outlet 32 and a slag discharge port. Its feed inlet 31 is communicated with the discharge end 22 of the separation and conveying bin 2. The stalks separated from the stem and leaf are sent into the feed inlet 31 of the tearing and breaking mill 3 by the conveying roller 23. The tearing and breaking mill 3 is common prior art, and this embodiment will not elaborate too much. In this embodiment, a hammer-type tearing and breaking mill 3 is preferably used. The stalks are broken in the tearing and breaking mill 3, and the broken fibers are screened out from the discharge outlet 32, and the remaining roots and other impurities are discharged from the slag discharge port.

[0040] Refer to Figure 1 , the selected roots are the finished products required by this equipment. The finished product conveying bin 4 is in the shape of a cylinder with both ends open. One end of the finished product conveying bin 4 is connected to the discharge outlet 32 of the tearing and breaking mill 3, so that the finished product fibers directly enter the finished product conveying bin 4. A finished product conveyor belt 41 is installed in the finished product conveying bin 4 along its own length direction. The finished product conveyor belt 41 conveys the finished product fibers to the other end of the finished product conveying bin 4. The user can connect the end of the finished product conveying bin 4 far from the tearing and breaking mill 3 to a conveying line or to a warehouse, thereby facilitating the transfer or storage of the finished product fibers.

[0041] Refer to Figure 1 , further, the finished product conveying bin 4 can be inclined, that is, its height gradually increases along the direction away from the tearing and breaking mill 3, thereby facilitating requirements such as cloth laying during storage; further, a cloth tube flexible connection 6 can be used between the inside of the finished product conveying bin 4 and the discharge outlet 32 of the tearing and breaking mill 3, thereby facilitating the adjustment of the direction of the finished product conveying bin 4 to meet the requirements of the cloth tube space scenario.

[0042] Refer to Figure 1In addition, since a large amount of dust will be generated during the stem crushing process, the end of the finished product conveying bin 4 close to the tearing and wall breaking machine 3 is connected to a dust collector 42. The dust collector 42 is a prior art and will not be elaborated in this embodiment. This embodiment preferably uses a pulse dust collector 42, which is connected to the top of the finished product conveying bin 4. When the finished fiber passes through the dust collector 42 and the connection point with the finished product conveying bin 4, the nearby air and dust are drawn into the dust collector 42. The dust collector 42 separates the air from the dust, thereby improving the environment of the processing site.

[0043] Reference Figure 1 After the finished fibers pass through the dust collector 42, some dust will still remain. A spray pipe 43 is installed at one end of the finished product conveying bin 4 away from the tearing and wall breaking machine 3. The spray pipe 43 is located at the top of the finished product conveying bin 4 and is connected to an external water source. The water source is sprayed into the finished product conveying bin 4 through the spray pipe 43, thereby better reducing dust; further, an atomizing nozzle can be installed on the spray pipe 43 to make the water source form water mist and spray it into the finished product conveying bin 4. The water droplets of the water mist are small and have a large coverage area. While ensuring the dust removal effect, it is easier to dry. The finished fibers can dry quickly after leaving the finished product conveying bin 4, and are not easily affected in terms of the quality of the finished fibers.

[0044] The implementation principle of Example 1 of the present application is as follows: the feed roller 11 and the conveying roller 23 both rotate under the action of the driving member 5. After the straw is unbundled, it enters the feed bin 1 and falls on the feed roller 11 for distribution. At this time, the adjacent straws are dispersed and are conveyed by the feed roller 11 to the conveying roller 23 in the separation and conveying bin 2. While the conveying roller 23 is conveying the straw, the stems and leaves of the straw will extend between the adjacent conveying rollers 23. Since the texture on the surface of the conveying roller 23 exerts a large friction force on the straw, the stems and leaves of the straw are torn off by the conveying roller 23 during the movement of the straw, thereby realizing the separation of the stems and leaves from the stems, and the stems and leaves fall below the separation and conveying bin 2. The stems enter the tearing and wall breaking machine 3 from the discharge end 22 of the separation and conveying bin 2 for crushing. The bundled straw can be directly put in to quickly obtain the required fiber material, which has a high processing efficiency.

[0045] Embodiment 2: Reference Figure 4 The main difference between this embodiment and the embodiment is that: a vibration plate 12 is installed in the feeding bin 1, and the vibration plate 12 is located above the feeding roller 11. After the unbundled straw enters the feeding bin 1, it falls on the vibration plate 12; further, the vibration plate 12 can be provided with two mutually symmetrical pieces to increase the receiving effect of the vibration plate 12 on the straw. A vibration motor 121 is fixedly installed on the lower end surface of the vibration plate 12. When the vibration motor 121 is started, it drives the vibration plate 12 to vibrate continuously. After the straw falls on the vibration plate 12, the vibration plate 12 vibrates, thereby causing the adjacent straw to be quickly dispersed.

[0046] Reference Figure 4, both vibrating plates 12 are inclined, and the ends close to each other form a blanking gap 122. The scattered straws fall onto the feeding roller 11 from the blanking gap 122. The length direction of the blanking gap 122 is the same as the length direction of the feeding roller 11, so as to ensure that the straws are parallel to the feeding roller 11 after falling, and improve the cloth feeding effect.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
