Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a conveying device and a material crushing system. Background Technology

[0002] In industrial and agricultural production practices, many materials are easy to be sucked up by wind, such as grains and straw. In the process of collecting, transporting and processing such materials, it is common to use a blower as a conveying device to directly suck up the materials and then blow them to a designated location.

[0003] While this can meet basic production needs, it also causes rapid wear and tear on the impeller, blades, and casing of the blower as materials pass through it. This leads to frequent maintenance or replacement of the blower during production, increasing production costs and affecting production efficiency. In particular, when conveying materials containing sand or with a hard texture, the blower blades or casing may be worn through in a short time, which is not conducive to extending the service life of the conveying equipment. Utility Model Content

[0004] In view of this, the present invention aims to provide a conveying device to improve the service life of the conveying device.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A conveying device includes a solid-gas separator having a suction port, a discharge port and an exhaust port, a fan connected to the exhaust port, a conveying pipe connected to the exhaust port of the fan, and a windproof feeding device provided on the discharge port.

[0007] The outlet of the windproof feeding device is connected to the conveying pipe;

[0008] The blower is capable of creating negative pressure in the solid-gas separator and is capable of blowing the material in the conveying pipe.

[0009] Furthermore, the windproof feeding device includes a first windproof unloader connected between the discharge port and the conveying pipe.

[0010] Furthermore, the windproof feeding device includes a first windproof unloader, a screening assembly, and a first pipe body connected in series between the discharge port and the conveying pipe;

[0011] The first tube is set lower along the conveying direction of the conveying pipe.

[0012] Furthermore, a three-way valve is provided at the outlet of the first windproof unloader, and the two outlet ends of the three-way valve are respectively provided with the screening component and the third pipe body, and the outlet end of the third pipe body is connected to the conveying pipe;

[0013] The outlet end of the third tube is set lower along the conveying direction of the conveying pipe.

[0014] Furthermore, the windproof feeding device includes a second windproof unloader located at the discharge port, a screening component located at the outlet of the second windproof unloader, and a third windproof unloader located at the outlet of the screening component.

[0015] The outlet of the third windproof unloader is connected to the conveying pipe.

[0016] Furthermore, a three-way valve is provided at the outlet of the second windproof unloader, and the two outlet ends of the three-way valve are respectively provided with the screening component and the third pipe body, and the outlet end of the third pipe body is connected to the third windproof unloader.

[0017] Furthermore, the conveying pipe is equipped with an openable and closable inspection door;

[0018] The inspection door is located at the bottom of the conveying pipe and extends along the conveying direction of the conveying pipe.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] (1) The conveying equipment described in this utility model is equipped with a solid-gas separator, so the material will not enter the fan during the conveying process, which can reduce the impact and wear on the fan and help improve the service life of the conveying equipment. At the same time, the material will not be hit by the fan blades, effectively ensuring its integrity, and making more materials suitable for conveying by this device. The fan creates negative pressure in the solid-gas separator, which can quickly draw in the gas containing the material. After being separated by the solid-gas separator, the solid material enters the conveying pipe through the windproof feeding device. At the same time, the fan directly supplies air to the conveying pipe, using wind power to push the material forward, which improves the overall operating efficiency. The conveying equipment has a compact overall structure, which is more conducive to being mounted on a mobile chassis for field or site operations, reducing the transportation links of straw or grain and improving the level of agricultural modernization.

[0021] (2) The first windproof unloader can block the reverse flow of air in the conveying pipe to the discharge port of the solid-gas separator, reduce the energy consumption of material conveying, and at the same time improve the transition efficiency of material from the separator to the conveying pipe, making the whole conveying process smoother.

[0022] (3) A screening component is set up to screen the material before it enters the conveying pipe. This can separate out materials that do not meet the requirements, ensure the purity and uniformity of the conveyed material, and meet the requirements of subsequent processing for material quality. The windproof feeding device adopts a series of first windproof unloader, screening component and first pipe body. The first pipe body is set at an inclination along the conveying direction, which can screen the material discharged by the first windproof unloader and then convey the screened material to the conveying pipe through the first pipe body. The material is conveyed by the dual action of gravity and wind force, while preventing the material from flowing back in the first pipe body.

[0023] (4) A three-way valve is set up so that the flow direction of the material discharged from the first windproof unloader can be selected. The connection path of the three-way valve can be selected as needed. When screening is required, the material is sent to the screening component. When screening is not required, the material is sent directly to the conveying pipe. The operation is convenient and quick.

[0024] (5) A screening component is set up to screen the material before it enters the conveying pipe. This can separate out materials that do not meet the requirements, ensure the purity and uniformity of the conveyed material, and meet the requirements of subsequent processing for material quality. The second and third windproof unloaders play a windproof role before and after screening, respectively. This prevents the conveying airflow from affecting the stability of the screening process and avoids the material after screening from being disturbed by the airflow when it enters the conveying pipe, thus ensuring the efficient connection between screening and conveying.

[0025] (6) A three-way valve is set up so that the flow direction of the material discharged by the second windproof unloader can be selected. The connection path of the three-way valve can be selected as needed. When screening is required, the material is sent to the screening component. When screening is not required, the material is sent directly to the third windproof unloader. The operation is convenient and quick.

[0026] (7) Setting the inspection door at the bottom of the conveying pipe and extending it along the conveying direction is more in line with the flow and accumulation characteristics of materials in the conveying pipe. If the material gets blocked during the conveying process, it will usually accumulate at the bottom of the pipe. The inspection door at the bottom makes it easy to clean the blockage directly. The design that extends along the conveying direction expands the inspection range and allows for more comprehensive inspection and maintenance of the inside of the conveying pipe, further improving the convenience and thoroughness of the inspection.

[0027] This utility model also proposes a material crushing system to improve the service life of the material crushing system.

[0028] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0029] A material crushing system includes the aforementioned conveying equipment.

[0030] Furthermore, the material crushing system includes a crusher;

[0031] The suction port is sealed to the outlet of the crusher and creates a negative pressure in the crusher so that the inlet of the crusher can suck up the material.

[0032] Furthermore, the material crushing system includes a receiving device that receives material at the outlet of the conveying pipe;

[0033] The receiving device can be connected to the receiving container and can adjust the feeding of the material into the receiving container.

[0034] The material crushing system described in this utility model, through the aforementioned conveying equipment, can achieve immediate separation and conveying of crushed materials, avoiding the accumulation of crushed materials inside the crusher, reducing secondary wear on the crusher, and improving the continuity of crushing operations. The high efficiency of the conveying equipment and the synergy with the crushing system shorten the overall process time from crushing to subsequent processing, improve the production efficiency of the entire crushing system, and reduce the system's energy consumption.

[0035] In addition, the suction port of the conveying equipment is sealed to the outlet of the crusher and creates negative pressure inside the crusher, enabling the crusher inlet to automatically suck up materials. This forms an integrated negative pressure system from material suction, crushing to separation and conveying, eliminating the need for additional material conveying equipment to feed the crusher, saving equipment costs and space. At the same time, the negative pressure state can effectively prevent dust generated during the crushing process from overflowing, improving the working environment and reducing the harm of dust to operators and pollution to equipment.

[0036] In addition, an adjustable receiving device is installed at the outlet of the conveying pipe, which can flexibly control the output speed and output volume of the material according to the size of the receiving container and the required amount of material, avoiding material overflow that would cause waste and pollution. By setting a discharge pipe with a steering mechanism, the position of material discharge can be easily adjusted, which is more conducive to conveying materials to trucks or hoppers during field operations. The convenient connection between the receiving device and the receiving container realizes the seamless docking of materials from the conveying pipe to the storage container, reducing material loss during the transfer process, improving the efficiency and standardization of material collection, and adapting to the needs of different holding scenarios, thus enhancing the practicality of the crushing system.

[0062] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0065] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0066] In this utility model, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0067] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0068] An embodiment of the first aspect of this utility model provides a conveying device to improve the service life and production efficiency of the conveying device.

[0069] In industrial and agricultural production practices, many materials are easy to be sucked up by wind, such as grains and straw. In the process of collecting, transporting and processing such materials, it is common to use a blower as a conveying device to directly suck up the materials and then blow them to a designated location.

[0070] While this can meet basic production needs, it also causes rapid wear and tear on the impeller, blades, and casing of the blower as materials pass through it. This leads to frequent maintenance or replacement of the blower during production, increasing production costs and affecting production efficiency. In particular, when conveying materials containing sand or with a hard texture, the blower blades or casing may be worn through in a short time, which is not conducive to extending the service life of the conveying equipment.

[0071] At the same time, although some materials are suitable for pneumatic conveying, they are fragile and will be severely broken after being hit by the fan blades, resulting in a decline in quality and waste of resources. Therefore, other methods of conveying must be used, which is not conducive to expanding the application range of conveying equipment.

[0072] In view of this, in order to overcome the shortcomings of the prior art, the conveying device in this embodiment combines... Figure 1 As shown, the overall design includes a solid-gas separator 1 with a suction port 101, a discharge port 102 and an exhaust port 103, a fan 2 connected to the exhaust port 103, a conveying pipe 3 connected to the exhaust port of the fan 2, and a windproof feeding device 4 provided on the discharge port 102.

[0073] The outlet of the windproof feeding device 4 is connected to the conveying pipe 3. The blower 2 can create negative pressure in the solid-gas separator 1, and the blower 2 can blow the material in the conveying pipe 3.

[0074] Therefore, by setting up the solid-gas separator 1, the material will basically not enter the blower 2 during the conveying process, which can reduce the impact and wear on the blower 2 and help extend the service life of the conveying equipment. The blower 2 creates negative pressure in the solid-gas separator 1, which can quickly draw in the gas containing the material. After being separated by the solid-gas separator, the solid material enters the conveying pipe 3 through the windproof feeding device 4. At the same time, the blower 2 directly supplies air to the conveying pipe 3, using wind power to propel the material forward, thereby improving the overall operating efficiency.

[0075] Secondly, the windproof feeding device 4 effectively prevents the airflow in the conveying pipe 3 from impacting the discharge port 102 of the solid-gas separator 1, ensuring the stable falling of the separated material, preventing material accumulation and blockage, and enhancing the reliability of equipment operation. The overall structure of the conveying equipment is compact, making it easier to mount on a mobile chassis for field or site operations, reducing the transportation links of straw, grain, etc., and improving the level of agricultural modernization.

[0076] Based on the above overview, specifically taking the conveying of straw fragments as an example, due to the action of the blower 2, external materials are drawn into the solid-gas separator 1 through the suction port 101. The solid materials then descend and enter the conveying pipe 3 through the windproof feeding device 4. Simultaneously, under the action of the blower 2, the airflow in the solid-gas separator 1 flows towards the blower 2. The airflow generated by the blower 2 is discharged through the conveying pipe 3, allowing the material to be smoothly conveyed out of the conveying pipe 3. The suction port 101 can be equipped with a second pipe body 104, and the suction position of the conveying equipment can be adjusted through the second pipe body 104.

[0077] Continue to refer to Figure 1 As shown, in order to enhance the conveying function of the conveying pipe 3, an auxiliary fan 5 is provided on the conveying pipe 3. The auxiliary fan 5 can supply air into the conveying pipe 3 to increase the air flow rate inside the conveying pipe 3.

[0078] This arrangement, with the addition of an auxiliary fan 5 to the conveying pipe 3, allows for flexible replenishment of airflow based on the amount of material within the pipe and the length of the conveying distance, further increasing the air velocity within the pipe. This design effectively solves the problem of insufficient conveying power during long-distance conveying or when materials are thick or heavy, preventing material from stagnating within the pipe and ensuring the continuity and stability of material conveying. Furthermore, it can adapt to the conveying needs of different types and states of materials, expanding the equipment's applicability.

[0079] Specifically, there is no limitation on the number of auxiliary fans 5 in this embodiment, as long as they can meet the airflow requirements for material conveying within the conveying pipe 3. Furthermore, the location of the auxiliary fans 5 can be selected based on the actual equipment layout. Preferably, the angle between the outlet direction of the auxiliary fan 5 and the conveying pipe 3 is acute, which makes it difficult for materials to enter the auxiliary fan 5.

[0080] Regarding the specific form of the windproof feeding device 4, in some possible embodiments, the windproof feeding device 4 includes a first windproof unloader connected between the discharge port 102 and the conveying pipe 3.

[0081] In this way, the first windproof unloader can ensure the negative pressure state of the solid-gas separator and block the reverse flow of air in the conveying pipe to the discharge port of the solid-gas separator, reduce the energy consumption of material conveying, and improve the transition efficiency of material from the separator to the conveying pipe, making the whole conveying process smoother.

[0082] Reference Figure 2 As shown, in some other possible embodiments, the windproof feeding device 4 includes a first windproof unloader 402, a screening assembly 405, and a first pipe body 401 connected in series between the discharge port 102 and the conveying pipe 3. The first pipe body 401 is arranged gradually downwards along the conveying direction of the conveying pipe 3. The screening assembly 405 can be in the form of existing screening equipment such as a reciprocating screen, a vibrating screen, or a drum screen.

[0083] Thus, by setting up the screening component 405, the material is screened before entering the conveying pipe 3, which can separate out materials that do not meet the requirements, ensuring the purity and uniformity of the conveyed material and meeting the material quality requirements of subsequent processing. The windproof feeding device 4 adopts a first windproof unloader 402, screening component 405 and first pipe 401 connected in series, and the first pipe 401 is inclined along the conveying direction, which can screen the material discharged from the first windproof unloader 402, and then pass the screened material through the first pipe 401, using the dual action of gravity and wind force to assist in the material conveying, while preventing the material from flowing back in the first pipe 401.

[0084] The conveying pipe 3 can be configured as a horizontal section and an elevating section. Material enters from the horizontal section and is discharged through the elevating section, facilitating feeding to higher material receiving containers, such as truck beds and storage silos. A curved pipe transitions between the horizontal and elevating sections to improve material flow. It should be understood that the term "horizontal section" does not refer to an absolutely horizontal position, but rather to its position relative to the elevating section. The horizontal section is positioned horizontally or gradually upwards from the exhaust port of fan 2 towards the airflow direction.

[0085] Reference Figure 3 As shown, in some other possible embodiments, a three-way valve 9 is provided at the outlet of the first windproof unloader 402. The two outlet ends of the three-way valve 9 are respectively provided with a screening component 405 and a third pipe body 901. The outlet end of the third pipe body 901 is connected to the conveying pipe 3. The outlet end of the third pipe body 901 is set lower along the conveying direction of the conveying pipe 3.

[0086] With this three-way valve configuration, the flow direction of the material discharged from the first windproof unloader 402 can be selected, and the connection path of the three-way valve 9 can be selected as needed. When screening is required, the material is directed to the screening component 405, and when screening is not required, the material is directly directed to the conveying pipe 3. The operation is convenient and quick.

[0087] Specifically, the outlet ends of the first pipe body 401 and the third pipe body 901 are both inserted into the conveying pipe 3, and the part of the part inserted into the conveying pipe 3 near the fan 2 extends into the conveying pipe 3, so as to further prevent the material from being blown by the wind and flowing back, and improve the material conveying effect.

[0088] Reference Figure 4As shown, in some other possible embodiments, the windproof feeding device 4 includes a second windproof unloader 403 provided at the discharge port 102, a screening component 405 provided at the outlet of the second windproof unloader 403, and a third windproof unloader 404 provided at the outlet of the screening component 405, with the outlet of the third windproof unloader 404 connected to the conveying pipe 3.

[0089] Specifically, the screening component 405 can be an existing screening equipment such as a reciprocating screen, vibrating screen, or drum screen, to send large particles into the third windproof unloader 404, and screen out fine dust for further processing. Of course, depending on actual needs and the different materials, small materials can also be sent into the windproof unloader 404 for long-distance transportation, while large particles can be discharged through chutes or other conveying equipment for further processing.

[0090] In this way, by setting up the screening component 405, the material is screened before entering the conveying pipe 3, which can separate out materials that do not meet the requirements, ensuring the purity and uniformity of the conveyed material and meeting the quality requirements of subsequent processing. The second windproof unloader 403 and the third windproof unloader 404 play a windproof role before and after screening, respectively, preventing the conveying airflow from affecting the stability of the screening process, and avoiding airflow interference to the screened material when entering the conveying pipe 3, ensuring efficient connection between screening and conveying.

[0091] Reference Figure 5 As shown, in some other possible embodiments, a three-way valve 9 is provided at the outlet of the second windproof unloader 403. The two outlet ends of the three-way valve 9 are respectively provided with a screening component 405 and a third pipe body 901. The outlet end of the third pipe body 901 is connected to the third windproof unloader 404. By providing the three-way valve, the flow direction of the material discharged from the second windproof unloader 403 can be selected. The connection path of the three-way valve 9 can be selected as needed. When screening is required, the material is directed to the screening component 405; when screening is not required, the material is directly directed to the third windproof unloader 404, making operation convenient and quick.

[0092] Reference Figure 6 and Figure 7 As shown, a discharge pipe 8 is pivotally connected to the outlet end of the conveying pipe 3. The discharge pipe 8 has a steering mechanism 801 and rotates relative to the conveying pipe 3 through the steering mechanism 801. By setting the discharge pipe 8 with the steering mechanism 801, the position of material discharge can be easily adjusted, which is more conducive to conveying materials to trucks or hoppers during field operations.

[0093] Specifically, the inner diameter of the discharge pipe 8 is equal to the outer diameter of the conveying pipe 5, and the discharge pipe 8 is rotatably sleeved on the outside of the conveying pipe 5. The steering mechanism 801 includes a gear ring 8011 sleeved on the discharge pipe 8, a worm gear 8012 rotatably connected to the conveying pipe 5, a gear 8013 coaxially fixed with the worm gear 8012, a worm 8014 meshing with the worm gear 8012, and a motor 8015 driving the worm 8014 to rotate. The gear 8013 meshes with the gear ring 8011, thereby driving the discharge pipe 8 to rotate through the motor 8015.

[0094] In addition, regarding the form of inspection door 301, refer to Figure 6 and Figure 7 As shown, it can also be set at the front end of the conveying pipe 3, and the conveying pipe 3 can be set to convey material at an upward angle. The inspection door 301 is hinged to one side of the inlet of the conveying pipe 3 and is connected to a counterweight 302. The counterweight 302 can apply a force to the inspection door 301 to close the inlet of the conveying pipe 3. When the material on the inspection door 301 reaches a certain weight, the inspection door 301 will automatically flip over to discharge the material, and under the action of the counterweight 302, the inspection door 301 will be closed again.

[0095] Reference Figures 1 to 7 Regarding the specific form of the solid-gas separator 1, a cyclone separator can be used. Cyclone separators utilize centrifugal force to achieve solid-gas separation, offering advantages such as simple structure, high separation efficiency, and convenient maintenance. Cyclone separators can rapidly separate materials at high airflow velocities and exhibit excellent separation effects on various materials, including granular and powdery materials. They are suitable for quickly separating materials and gases in conveying equipment, laying a solid foundation for subsequent material transport while reducing equipment manufacturing and operating costs.

[0096] It is understandable that the solid-gas separator 1 can also be other devices or equipment that can separate solids and liquids, such as bag filters, anti-clogging unloading bins, air separation bins, etc., as long as the material can be separated from the air, and there is no limitation on the specific type or structure of the solid-gas separator 1.

[0097] To facilitate maintenance of the conveying pipe 3, an openable and closable inspection door 301 is provided on the conveying pipe 3. This inspection door 301 facilitates routine maintenance and troubleshooting of the equipment. When material blockage, pipe wall wear, or internal residual material needs to be cleaned from the conveying pipe 3, the operation can be performed directly by opening the inspection door 301, without disassembling the entire conveying pipe 3. This reduces maintenance time and workload, lowers equipment maintenance costs, and ensures the continuous and stable operation of the equipment.

[0098] Furthermore, the inspection door 301 is located at the bottom of the conveying pipe 3 and extends along the conveying direction of the conveying pipe 3. Positioning the inspection door 301 at the bottom of the conveying pipe 3 and extending it along the conveying direction better suits the flow and accumulation characteristics of materials within the conveying pipe 3. If material blockage occurs during conveying, it usually accumulates at the bottom of the pipe; the bottom inspection door 301 facilitates direct cleaning of the blockage. The design extending along the conveying direction expands the maintenance range, allowing for more comprehensive inspection and maintenance of the interior of the conveying pipe 3, improving the convenience and thoroughness of maintenance.

[0099] In this embodiment, the first windproof unloader 402, the second windproof unloader 403, and the third windproof unloader 404 can all be star-shaped unloaders, which have high unloading efficiency. In other embodiments, they can be counterweight flap valves.

[0100] A second aspect of this utility model provides a material crushing system, see below. Figure 8 As shown, the material crushing system includes the aforementioned conveying equipment.

[0101] With this configuration, the material crushing system of this embodiment, through the aforementioned conveying equipment, can achieve immediate separation and conveying of crushed materials, preventing the accumulation of crushed materials within the crusher 6, reducing secondary wear on the crusher 6, and improving the continuity of the crushing operation. The high efficiency of the conveying equipment and the synergy with the crushing system shorten the overall process time from crushing to subsequent processing, improve the overall production efficiency of the crushing system, and reduce the system's energy consumption.

[0102] The material crushing system includes a crusher 6, with a suction port 101 sealed to the outlet of the crusher 6. A negative pressure is created within the crusher 6, allowing material to be drawn in through its inlet. Alternatively, a second pipe 104 can be sealed at one end to the outlet of the crusher 6 and at the other end to the suction port 101 of a conveying device. This creates a sealed connection between the conveying device and the outlet of the crusher 6, generating negative pressure within the crusher 6 and enabling automatic material intake. This forms an integrated negative pressure system that handles material intake, crushing, separation, and conveying. No additional material conveying equipment is needed to supply material to the crusher 6, saving equipment costs and space. Furthermore, the negative pressure effectively prevents dust from spilling out during the crushing process, improving the working environment and reducing the harm to operators and equipment contamination caused by dust.

[0103] Of course, if operating in a fixed location, materials can also be supplied to the crusher through existing equipment such as conveyor belts, auger conveyors, or chutes. Users can make flexible use of these methods according to the actual scenario.

[0104] In addition, the material crushing system includes a receiving device 7 connected to the outlet of the conveying pipe 3. The receiving device 7 can connect to a receiving container and can adjust the material flow into the container. The adjustable receiving device 7 at the outlet of the conveying pipe 3 allows for flexible control of the material output speed and volume based on the size of the receiving container and the required material quantity, preventing material overflow and waste / contamination. The convenient connection between the receiving device 7 and the receiving container enables seamless material transfer from the conveying pipe 3 to the storage container, reducing material loss during transfer, improving material collection efficiency, adapting to different storage scenarios, and enhancing the practicality of the crushing system.

[0105] Specifically, taking straw crushing as an example, the receiving device 7 includes a hopper 701 and a material valve 702. For convenient bagging, the conveying pipe 3 in this embodiment includes a horizontal section and an inclined lifting section. Material enters from the horizontal section and exits from the inclined lifting section. The top inlet of the hopper 701 is located below the outlet of the conveying pipe 3, capable of holding the straw fragments discharged from the conveying pipe 3. A discharge port 102 is provided at the bottom of the hopper 701, and the material valve 702 is located on the discharge port 102 to control the material discharge and stop of the hopper 701. In use, simply place the bag containing the straw fragments onto the bottom of the discharge port 102 for bagging.

[0106] Understandably, conveying equipment can also be used. Figure 6 and Figure 7 As shown, the outlet end of the conveying pipe 3 is pivotally connected to the discharge pipe 8. The discharge pipe 8 has a steering mechanism 801 and rotates relative to the conveying pipe 3 via the steering mechanism 801. By providing a discharge pipe with a steering mechanism 801, the position of material discharge can be easily adjusted, which is more conducive to conveying materials to trucks or hoppers during field operations.

[0107] In practical applications, depending on the characteristics and cleanliness of the materials, the receiving device 7 can be an existing air-separation chamber or an anti-clogging discharge chamber. The material discharged from the conveying pipe 3 is directly blown into the air-separation chamber or the anti-clogging discharge chamber for further air separation to remove floating dust, debris, and light impurities. The material can then be directly collected below the air-separation chamber or the anti-clogging discharge chamber. Of course, it is more convenient to arrange the receiving device 7 below the outlet of the air-separation chamber or the anti-clogging discharge chamber.

[0108] Understandably, depending on the application scenario, the material crushing system can be mounted on a mobile chassis for field operations. To further improve efficiency, the conveying pipe 3 can be equipped with a universal mechanism, allowing it to change the discharge direction as needed. The hopper 701 can also be a large cargo box mounted on a mobile chassis, or other transport vehicles working in conjunction with it, such as large trucks or dump trucks, thereby replacing the bagging step to improve field operation efficiency, achieve rapid harvesting, and avoid losses caused by climate change.

The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this utility model can have various modifications and variations.
