[0027] The present utility model provides a kind of sorghum harvesting and crushing integrated equipment.

[0028] Please refer to Figures 1 to 4 In an embodiment of the present utility model, the sorghum harvesting and crushing integrated equipment includes a frame 10, a harvesting mechanism 20, a crushing mechanism 30, and a control system 40. The harvesting mechanism 20, the crushing mechanism 30, and the control system 40 are arranged on the frame 10. The crushing mechanism 30 is located below the harvesting mechanism 20. The control system 40 is electrically connected with the harvesting mechanism 20 and the crushing mechanism 30.

[0029] The frame 10 serves as the basic structure of the entire equipment, and provides a mounting platform and support for the harvesting mechanism 20, the crushing mechanism 30, and the control system 40. The design of the frame 10 needs to have sufficient strength and stability to withstand various forces and vibrations generated during the harvesting and crushing processes, while ensuring the smooth operation of the equipment in the field.

[0030] The harvesting mechanism 20 is located at the front end of the device and is mainly responsible for the harvesting of sorghum. It usually includes a harvesting head 21 and a conveying device 22. The harvesting head 21 can accurately cut off the sorghum plants, while the conveying device 22 conveys the harvested sorghum heads to the crushing mechanism 30. The design of the harvesting mechanism 20 needs to consider the growth characteristics of sorghum and the field working environment to ensure efficient and low-loss completion of the harvesting task.

[0031] The crushing mechanism 30 is installed below the harvesting mechanism 20 and is used to crush the conveyed sorghum heads. The crushing mechanism 30 usually consists of a crushing shell 31, a crushing roller 32, and a powder outlet assembly 33. The crushing roller 32 applies pressure to the sorghum heads through rotation, separating the grains from the stalks and crushing them into powder; the powder outlet assembly 33 is used to screen the crushed sorghum powder to ensure that its particle size meets the processing requirements.

[0032] The control system 40 monitors the operating state of each component in real time through sensors, such as vibration frequency, conveying speed, and crushing roller 32 rotation speed. According to the information fed back by the sensors, the control system 40 automatically adjusts the operating parameters of each component, such as adjusting the vibration frequency of the vibration motor 333 to optimize the screening efficiency, or adjusting the conveying speed of the conveying device 22 to ensure smooth conveying of sorghum heads. In this way, the control system 40 realizes the coordinated work between each component, ensuring that the device is always in the best working state.

[0033] When the device starts, the harvesting head 21 of the harvesting mechanism 20 first cuts the sorghum plants, separating the sorghum heads from the plants. The cut sorghum heads are sent to the crushing mechanism 30 through the conveying device 22. The conveying speed of the conveying device 22 is adjusted in real time by the control system 40 according to the yield of sorghum and the processing capacity of the device to ensure that the sorghum heads can enter the crushing mechanism 30 smoothly and uniformly. After the sorghum heads enter the crushing mechanism 30, the crushing roller starts to rotate, applying pressure to the sorghum heads, causing the grains to separate from the stalks and be crushed into powder. At the same time, the screen screens the crushed sorghum powder to ensure that its particle size meets the processing requirements. The screened sorghum powder is discharged from the device through the discharge port and enters the subsequent collection or processing link. In the whole process, the control system 40 monitors the operating state of each component in real time and adjusts the operating parameters of the device according to the feedback information to ensure that the device is always in the best working state.

[0034] Through the cooperation of the above-mentioned components, the sorghum harvesting and crushing integrated equipment can complete the harvesting and crushing of sorghum at one time, greatly improving the sorghum processing efficiency. Compared with the traditional step-by-step harvesting and crushing processing mode, the device reduces the loss of sorghum grains during the harvesting process, significantly improves the crushing powder yield. At the same time, the automatic design of the device reduces the degree of manual intervention and reduces the labor input, thereby effectively reducing the production cost. In addition, the efficient operation of the device also reduces the operation time and improves the land utilization rate, bringing significant economic benefits to sorghum growers.

[0035] In an embodiment, please refer to Figures 1 to 4 The harvesting mechanism 20 includes a harvesting head 21, a conveying device 22, and a grain collecting device 23, the conveying device 22 is arranged on the rack 10, the harvesting head 21 is arranged at the front end of the conveying device 22, the grain collecting device 23 is arranged at the end of the conveying device 22, and the crushing mechanism 30 is located below the grain collecting device 23.

[0036] The harvesting head 21 is the front end part of the device, mainly used for harvesting sorghum ears. It is usually equipped with cutting blades or cutters, which can accurately separate sorghum ears from the plants. The design of the harvesting head 21 needs to consider the growth height and density of sorghum to ensure cutting efficiency and cutting quality. Its structure is usually adjustable, which can adjust the cutting height according to the actual growth of sorghum, avoiding unnecessary damage to the sorghum plants during harvesting.

[0037] The conveying device 22 is a key component connecting the harvesting head 21 and the grain collecting device 23, which functions to convey the harvested sorghum ears from the harvesting head 21 to the grain collecting device 23. The conveying device 22 usually adopts the form of a conveyor belt or a screw conveyor, which can automatically adjust the conveying speed according to the conveying amount of sorghum. The design of the conveying device 22 needs to ensure that the sorghum ears do not jam or fall during the conveying process, while reducing the loss of grains during the conveying process.

[0038] The grain collecting device 23 is located at the end of the conveying device 22, mainly used for collecting the conveyed sorghum ears and preliminarily separating them into grains and ear axes. The device is usually equipped with a threshing cylinder and a screen, the threshing cylinder separates the grains from the ear axes by rotating and applying mechanical force, and the screen is used to screen the separated grains to avoid impurities. The design of the grain collecting device 23 needs to ensure efficient threshing and screening effect, while reducing the breakage rate of grains.

[0039] The crushing mechanism 30 is located below the grain collecting device 23, which is used for further crushing of the collected sorghum grains. Its main components include a crushing roller, a screen and a discharge port. The crushing roller applies pressure to the sorghum grains through rotation to crush them into powder; the screen is used to screen out sorghum powder that meets the particle size requirements, ensuring product quality; the discharge port discharges the screened sorghum powder from the equipment for subsequent collection or processing.

[0040] After the device is started, the cutting blades of the harvesting head 21 begin to work, and according to the set cutting height, the sorghum ears are accurately cut from the plants. The cut sorghum ears enter the first end of the conveying device 22. The conveying device 22 automatically adjusts the conveying speed according to the conveying amount of the sorghum, and stably conveys the sorghum ears to the grain collecting device 23. During the conveying process, the structural design of the conveying device 22 ensures that the sorghum ears do not block or fall off, and at the same time reduces the loss of grains during the conveying process. After the sorghum ears reach the grain collecting device 23, the threshing drum begins to rotate, applying mechanical force to the sorghum ears to separate the grains from the ear shaft. The separated grains pass through the grain collecting device 23 into the crushing mechanism 30. After the grains enter the crushing mechanism 30, the crushing roller begins to rotate, applying pressure to the sorghum grains to crush them into powder. The screen further screens the crushed sorghum powder to ensure that its particle size meets the processing requirements. The screened sorghum powder is discharged from the equipment through the discharge port and enters the subsequent collection or processing link.

[0041] During the entire working process, the control system 40 monitors the running state of each component in real time, and adjusts the operating parameters of the device according to the feedback information, to ensure that the device is always in the best working state.

[0042] In an embodiment, referring to Figures 1 to 4 , the grain collecting device 23 includes a vibrating screen assembly 231, a grain conveying assembly 232, a stalk discharge assembly 233 and a grain collecting box 234. The grain conveying assembly 232 is arranged below the vibrating screen assembly 231, and the stalk discharge assembly 233 is arranged on the side of the vibrating screen assembly 231, for discharging the separated sorghum stalks from the equipment. The grain collecting box 234 is arranged on the rack 10 and located at the end of the grain conveying assembly 232, for collecting the screened grains.

[0043] The vibrating screen assembly 231 is the core component of the grain collecting device 23, and its main function is to continuously roll and move the harvested sorghum ears for screening treatment, to separate the sorghum grains and stalks, thereby accelerating the separation process of the grains and the stalks. The design of the vibrating screen assembly 231 needs to consider the screening efficiency and screening quality to ensure the purity and integrity of the sorghum grains.

[0044] The grain conveying assembly 232 is located below the vibrating screening assembly 231 and is mainly responsible for conveying the screened sorghum grains to the grain collection tank 234. This mechanism usually takes the form of a conveyor belt or a screw conveyor, which can automatically adjust the conveying speed according to the amount of grains being conveyed. The surface of the conveyor belt is designed with anti-slip texture to prevent grains from slipping off during the conveying process. The design of the grain conveying assembly 232 must ensure the stability and continuity of the sorghum grains during the conveying process, while reducing the breakage rate and loss rate of the grains.

[0045] The stem discharge assembly 233 is connected to the side of the vibrating screening assembly 231, which can smoothly convey the stems trapped on the stem collection tank to the outside of the equipment. The design of the stem discharge assembly 233 needs to consider the discharge efficiency and direction of the stems to avoid accumulation or blockage of the stems inside the equipment, while reducing interference with the normal operation of the equipment.

[0046] The grain collection tank 234 is installed on the rack 10 and located at the end of the grain conveying assembly 232, used to collect the screened sorghum grains. The capacity of the collection tank is designed according to the processing capacity and operation time of the equipment, which can store a certain amount of sorghum grains. The grain collection tank 234 is equipped with moisture-proof and dust-proof devices inside to ensure the quality of the sorghum grains. In addition, the grain collection tank 234 is also equipped with a discharge port to facilitate users to transfer the collected grains to subsequent processing links or storage facilities.

[0047] When the sorghum ears pass through the conveying device 22 into the vibrating screening assembly 231, the vibrating device starts to work and generates periodic vibrations. The sorghum ears continue to roll and move in the vibration, and the sorghum grains gradually separate from the ear shaft and fall into the grain conveying assembly 232 below through the screen. Larger stems are trapped above the vibrating screening assembly 231 and await subsequent discharge.

[0048] The screened sorghum grains fall into the grain conveying assembly 232, and the conveyor belt or screw conveyor starts to work, smoothly conveying the grains to the grain collection tank 234. During the conveying process, the anti-slip texture design of the conveying mechanism ensures the stable conveying of the grains, avoiding the sliding and accumulation of the grains. At the same time, the conveying speed is automatically adjusted according to the amount of grains being conveyed, ensuring the continuity and efficiency of the conveying process.

[0049] The sorghum stems trapped on the vibrating screening assembly 231 are pushed by the conveying device 22 (such as a conveyor belt or a screw conveyor) to the discharge roller of the stem discharge assembly 233. The design of the discharge mechanism ensures that the stems can be smoothly discharged, avoiding accumulation or blockage inside the equipment, thereby ensuring the normal operation of the equipment.

[0050] The sieved and transported sorghum grains finally enter the grain collection box 234. The moisture-proof and dust-proof device inside the collection box ensures the quality of the grains, while the design of the discharge port facilitates the user to transfer the collected grains to the subsequent processing link or storage facility. Throughout the process, the control system 40 monitors the operating status of each component in real time and adjusts the operating parameters of the equipment according to the feedback information to ensure that the equipment is always in the best working condition.

[0051] Through the coordinated work of the above components, the vibration screening assembly 231 can quickly and accurately separate sorghum grains and stems, significantly improving the purity and integrity of the grains. The design of the grain conveying assembly 232 ensures the stability and continuity of the grains during transportation, reducing the breakage rate and loss rate of the grains. The efficient discharge function of the stem discharge assembly 233 avoids the accumulation or blockage of stems inside the equipment, improving the running stability of the equipment. The reasonable design of the grain collection box 234 provides a good storage environment for the collected grains, ensuring the quality of the grains.

[0052] In an embodiment, referring to Figures 1 to 4 , the vibration screening assembly 231 includes a support frame, a vibration motor 333 provided on the support frame, and a screen mesh connected with the output shaft of the vibration motor 333.

[0053] The support frame is the basic structure of the vibration screening assembly 231, used to fix the vibration motor 333 and the screen mesh, and to install them as a whole on the rack 10 of the equipment. The design of the support frame needs to have sufficient strength and stability to withstand the impact force and vibration generated during the vibration screening process. At the same time, the structural design of the support frame also needs to consider the installation position of the vibration motor 333 and the tensioning method of the screen mesh, to ensure that the vibration screening assembly 231 works smoothly and efficiently during operation. The support frame is usually made of high-strength steel and is fixed on the rack 10 by welding or bolt connection to ensure its firmness and reliability.

[0054] The vibration motor 333 is the power source of the vibration screening assembly 231, and its main function is to provide vibration power for the screen mesh. The vibration motor 333 is connected with the screen mesh through its output shaft, and can generate periodic vibration to make the sorghum heads on the screen mesh roll and move constantly under the vibration, thereby accelerating the separation of grains and stems. The vibration frequency and amplitude of the vibration motor 333 can be adjusted according to the characteristics of sorghum (such as grain size, stem hardness, etc.) to achieve the best screening effect. In addition, the vibration motor 333 is also equipped with a speed regulating device, which can adjust the vibration frequency in real time according to the operating state of the equipment and the processing requirements, to ensure the efficiency and stability of the screening process.

[0055] The screen is the core component of the vibrating screening assembly 231, used to separate the sorghum grains from the stems. The screen aperture is designed according to the size of the sorghum grains, usually made of metal wire or high-strength plastic material to ensure durability and screening accuracy. The screen is fixed on the support frame by a tensioning device, and the tensioning degree directly affects the screening effect and the service life of the screen. Reasonable tension can ensure that the screen maintains good elasticity during vibration, avoiding screen relaxation or deformation, thereby improving the screening efficiency and the purity of the grains. The design of the screen also needs to consider its anti-blocking performance to prevent the sorghum heads from blocking the screen holes during screening, affecting the screening effect.

[0056] When the device starts, the vibration motor 333 is first powered on and starts working. The output shaft of the vibration motor 333 produces periodic vibrations, which are transmitted to the screen through the connecting device. The screen starts to vibrate under the drive of the vibration motor 333, and the vibration frequency and amplitude are adjusted according to the pre-set parameters to adapt to the characteristics of sorghum. The conveying device 22 conveys the harvested sorghum heads to the screen of the vibrating screening assembly 231. Under the action of vibration, the sorghum heads roll and move continuously on the screen. The vibration frequency and amplitude of the vibration motor 333 make the grains of the sorghum heads gradually separate from the stem axis and fall into the grain conveying assembly 232 below through the aperture of the screen. Larger stems are intercepted above the screen, waiting to be discharged later. The screen of the vibrating screening assembly 231 continues to vibrate under the drive of the vibration motor 333, and the sorghum heads roll continuously on the screen, further accelerating the separation of grains and stems. The speed regulating device of the vibration motor 333 adjusts the vibration frequency in real time according to the running state of the device and the characteristics of sorghum, ensuring the efficiency and stability of the screening process. The tensioning device of the screen maintains the elasticity of the screen during vibration, preventing the screen from relaxing or deforming, thereby improving the screening efficiency and the purity of the grains. The sorghum stems intercepted on the screen are conveyed to the outside of the device by the conveying device 22 of the stem discharge assembly 233. The design of the stem discharge assembly 233 ensures that the stems can be smoothly discharged, avoiding accumulation or blockage inside the device, thereby ensuring the normal operation of the device. The screened sorghum grains are conveyed to the grain collection box 234 by the grain conveying assembly 232. The conveying speed of the grain conveying assembly 232 is automatically adjusted according to the conveying amount of the grains, ensuring the continuity and efficiency of the conveying process. Throughout the process, the control system 40 monitors the running state of each component in real time and adjusts the operating parameters of the device according to the feedback information, ensuring that the device is always in the best working condition.

[0057] The high-strength design of the support frame provides a stable operating foundation for the vibrating screen assembly 231, ensuring that the screen mesh maintains good elasticity during vibration and avoids slackening or deformation. The speed regulation device of the vibrating motor 333 can adjust the vibration frequency and amplitude in real time according to the characteristics of sorghum, significantly improving the screening efficiency and purity of the grains. The reasonable aperture design and anti-blocking performance of the screen mesh further optimize the screening effect, reducing the risk of sorghum panicles blocking the screen holes during screening. Ultimately, the efficient operation of the vibrating screen assembly 231 ensures the high-quality collection of sorghum grains, providing pure raw materials for subsequent crushing processing.

[0058] In an embodiment, referring to Figures 1 to 4 , the stem discharge assembly 233 includes a discharge roller, a guide plate, and a stem collection box. The discharge roller is located on the side of the vibrating screen assembly 231. The guide plate is installed at the outlet of the discharge roller, and the stem collection box is arranged at the end of the outlet of the discharge roller.

[0059] The discharge roller is the core component of the stem discharge assembly 233, and its main function is to discharge the sorghum stems separated by the vibrating screen assembly 231 from the equipment. The discharge roller is usually installed on the side of the vibrating screen assembly 231 and pushes the stems to the guide plate through rotational motion. The design of the discharge roller needs to consider its speed and thrust to ensure that the stems can be smoothly discharged while avoiding excessive mechanical load on the equipment. The guide plate is installed at the outlet of the discharge roller, and its main function is to guide the discharge direction of the stems to ensure that the stems can smoothly enter the stem collection box. The guide plate is usually designed with an inclined structure and can be adjusted according to the discharge speed and direction of the stems to avoid accumulation or rebound of the stems during discharge. The stem collection box is arranged at the end of the outlet of the discharge roller and is used to collect the discharged sorghum stems. The capacity of the stem collection box is designed according to the continuous operation time of the equipment and the discharge amount of the stems, and can accommodate a certain amount of stems to ensure that the equipment does not need to frequently clean the stem collection box during continuous operation. The stem collection box is usually equipped with a detachable cover and a discharge port to facilitate regular cleaning and transfer of the collected stems.

[0060] The vibration screening assembly 231 separates the grains from the stalks in the sorghum ears. After the screening is completed by the vibration screening assembly 231, the stalks are pushed to the discharge roller. The discharge roller starts rotating and pushes the stalks trapped on the screen to the guide plate. The rotation speed and pushing force of the discharge roller are adjusted according to the discharge requirements of the stalks, ensuring that the stalks can be smoothly discharged from the equipment. The guide plate guides the stalks pushed by the discharge roller to the stalk collection box. The inclination angle and structural design of the guide plate ensure that the stalks can smoothly enter the collection box, avoiding the accumulation or rebound of the stalks during the discharge process. The stalks finally enter the stalk collection box, and the design of the collection box can accommodate a certain amount of stalks to meet the continuous operation requirements of the equipment. When the amount of stalks in the collection box reaches a certain amount, the user can clean and transfer the stalks to the designated location through the discharge port.

[0061] During the entire process, the control system 40 monitors the running state of the discharge roller and the discharge of the stalks in real time, adjusts the rotation speed and pushing force of the discharge roller according to the feedback information, and ensures the efficient operation of the stalk discharge assembly 233.

[0062] The reasonable design and operation parameter adjustment of the discharge roller ensure that the stalks can be smoothly discharged from the equipment, avoiding the accumulation and blockage of the stalks inside the equipment. The inclined structural design of the guide plate further optimizes the discharge path of the stalks, improving the discharge efficiency. The capacity and discharge convenience design of the stalk collection box meet the continuous operation requirements of the equipment, reducing manual intervention. These optimized designs not only improve the operation efficiency of the stalk discharge assembly 233, but also realize the efficient discharge and collection of sorghum stalks.

[0063] In an embodiment, please refer to Figures 1 to 4 , an observation window is provided on one side of the grain collection box 234 for the operator to observe the storage of grains inside the box; a discharge port is provided at the bottom of the grain collection box 234 for discharging the collected grains.

[0064] The observation window is an important auxiliary device of the grain collection box 234, usually installed on one side of the collection box. Its main function is to provide an intuitive observation angle for the operator to understand the storage of grains in the box in real time. The observation window is usually made of transparent material (such as tempered glass) with good impact resistance and sealing performance, which can prevent dust and impurities from entering the box, and at the same time ensure that the operator can check the accumulation height and state of the grains at any time during the operation of the equipment, avoiding overflow or blockage caused by overfilling of the collection box.

[0065] The discharge port is a critical structure at the bottom of the grain collection tank 234, mainly used for quickly and efficiently discharging the collected sorghum grains. The design of the discharge port needs to consider the convenience and efficiency of discharging, and is usually equipped with adjustable valves or covers to control the discharging speed and direction according to actual needs. In some designs, the discharge port is also used in cooperation with the unloading auger or other conveying devices 22 to further improve the degree of automation of discharging.

[0066] After the vibration screening assembly 231 separates the sorghum grains from the stems, the grains enter the grain collection tank 234 through the conveying device 22. At this time, the operator can observe the storage condition of the grains in the tank through the observation window in real time. The design of the observation window enables the operator to timely discover that the grains are too high or other abnormal conditions during the operation of the equipment, and take appropriate measures such as suspending the equipment or cleaning the collection tank. When the amount of sorghum grains in the grain collection tank 234 reaches a certain amount, the operator confirms through the observation window that it is necessary to discharge. At this time, the equipment suspends the operation of the conveying device 22 to prevent new grains from entering the collection tank. The operator opens the valve or cover of the discharge port, and the grains in the collection tank are quickly discharged through the discharge port.

This design not only improves the collection efficiency, but also reduces the mixing of powders, ensuring the purity of the product.

[0081] The crushed sorghum powder enters the powder outlet shell 331 through the pipeline, first reaching the uppermost layer of the screen. The vibration motor 333 starts to work, generating exciting force to make the screen vibrate. The exciting force of the vibration motor 333 makes the screen vibrate at high frequency, and the sorghum powder continuously rolls and moves on the screen. The fine powder falls into the next level of screen through the screen aperture, while the coarse powder remains on the current screen. The design of the multi-level screen 334 allows the sorghum powder to be accurately separated into different particle sizes during the step-by-step screening process. The screened sorghum powder falls into the corresponding multi-level collection hopper 335. Each collection hopper is designed with an independent discharge port to facilitate the collection and storage of different particle size powders. This grading collection method ensures the purity and quality of the sorghum powder. The collected sorghum powder is discharged through the discharge port of the multi-level collection hopper 335 and enters the subsequent packaging or storage link. The entire screening and collection process is continuously carried out under the drive of the vibration motor 333, ensuring efficient operation of the powder outlet assembly 33.

[0082] The sealing design of the powder outlet shell 331 effectively prevents dust leakage and reduces environmental pollution. The adjustable exciting force and high-frequency vibration of the vibration motor 333 improve the screening efficiency and accuracy. The design of the multi-level screen 334 ensures that the particle size grading of the sorghum powder meets the processing requirements. The independent discharge port design of the multi-level collection hopper 335 further improves the collection efficiency, reduces the mixing of powders, and ensures the purity of the product.

[0083] In an embodiment, referring to Figures 1 to 4 , the multi-level screen 334 includes a top layer screen, a middle layer screen, and a bottom layer screen, and the mesh diameters of the top layer screen, the middle layer screen, and the bottom layer screen are gradually reduced. The multi-level collection hopper 335 includes a top layer collection hopper, a middle layer collection hopper, and a bottom layer collection hopper. The top layer screen, the middle layer screen, and the bottom layer screen are stacked on the mounting frame 332, the top layer collection hopper is arranged on one side of the top layer screen, the middle layer collection hopper is arranged on one side of the middle layer screen, and the bottom layer collection hopper is arranged on one side of the bottom layer screen.

[0084] The multi-level screen 334 and the multi-level collection hopper 335 of the powder outlet assembly 33 are the key parts to realize efficient classification of sorghum powder. The multi-level screen 334 includes a top layer screen, a middle layer screen, and a bottom layer screen, and the mesh diameters of the top layer screen, the middle layer screen, and the bottom layer screen are gradually reduced from top to bottom to adapt to the screening needs of sorghum powder of different particle sizes. The multi-level collection hopper 335 corresponds to each layer of screen and is used to accurately collect sorghum powder of different particle sizes. This design not only improves the screening efficiency, but also ensures the quality and purity of the product.

[0085] The top layer screen is the first layer in the multi-level screen 334, located at the top of the mounting frame 332. Its mesh diameter is relatively large, mainly used for screening out large particle size sorghum powder. This design can quickly remove coarse particles in sorghum powder, providing a basis for subsequent fine screening. The top layer screen is usually made of high-strength, wear-resistant metal materials to ensure its durability in high-load operation.

[0086] The middle layer screen is located below the top layer screen, with a mesh diameter smaller than the top layer screen but larger than the bottom layer screen. The main function of the middle layer screen is to further screen out medium-sized sorghum powder. Through the screening of the middle layer screen, medium-sized particles in the sorghum powder are separated and enter the corresponding collection hopper. The design of the middle layer screen optimizes the screening precision, ensuring that the particle size distribution of the sorghum powder is more uniform.

[0087] The bottom layer screen is the last layer in the multi-level screen 334, located at the bottom of the mounting frame 332.

The design of the bottom layer screen can ensure the precise separation of fine powder in the sorghum powder, meeting the needs of high-precision processing. The bottom layer screen usually uses high-precision screen materials to ensure the precision and efficiency of screening.

[0088] The multi-level collection hopper 335 includes top, middle and bottom layer collection hoppers, corresponding to each layer of screen. These collection hoppers are used to collect sorghum powder of different particle sizes after screening. Each collection hopper is designed with an independent discharge port, facilitating the collection and storage of screened powder separately. This design not only improves the collection efficiency, but also reduces the mixing of powder, ensuring the purity of the product.

[0089] The crushed sorghum powder enters the powder outlet shell 331 through the pipeline, first reaching the top layer of the screen. At this time, the vibration motor 333 starts to work, generating a vibration force to make the screen vibrate. The top layer of the screen has a larger mesh diameter, which can quickly screen out sorghum powder with larger particle size. These coarse particles are guided to the top layer of the collecting hopper through the vibration of the screen. The top layer of the collecting hopper is arranged on one side of the top layer of the screen, which can accurately collect these coarse particles. The sorghum powder screened by the top layer of the screen falls into the middle layer of the screen. The middle layer of the screen has a smaller mesh diameter, which can further screen out sorghum powder with medium particle size. These medium-sized powders are guided to the middle layer of the collecting hopper through vibration, and the middle layer of the collecting hopper is arranged on one side of the middle layer of the screen to ensure that these powders are accurately collected. The sorghum powder screened by the middle layer of the screen falls into the bottom layer of the screen. The bottom layer of the screen has the smallest mesh diameter, which can screen out the finest sorghum powder. These fine powders are guided to the bottom layer of the collecting hopper through vibration, and the bottom layer of the collecting hopper is arranged on one side of the bottom layer of the screen to ensure that the fine powders are accurately collected. After being screened by the multi-stage screen 334, sorghum powder of different particle sizes enters the corresponding multi-stage collecting hopper 335. Each collecting hopper discharges the powder through an independent discharge port into the subsequent packaging or storage link. The entire screening and collecting process is continuously carried out under the drive of the vibration motor 333, ensuring the efficient operation of the powder outlet assembly 33.

[0090] Through the reasonable design of the top layer of the screen, the middle layer of the screen and the bottom layer of the screen, and the accurate layout of the multi-stage collecting hopper 335, the powder outlet assembly 33 of the utility model realizes the efficient classification and accurate collection of sorghum powder.

[0091] In an embodiment, referring to Figures 1 to 4 , the powder outlet assembly 33 includes three guide plates, one guide plate is arranged between the top layer of the screen and the top layer of the collecting hopper, one guide plate is arranged between the middle layer of the screen and the middle layer of the collecting hopper, and one guide plate is arranged between the bottom layer of the screen and the bottom layer of the collecting hopper.

[0092] In the design of the powder outlet assembly 33, the guide plate is a key auxiliary component for guiding the sorghum powder after screening to smoothly enter the corresponding collecting hopper. A guide plate is arranged between each layer of screen and collecting hopper to ensure that the powder can move along the predetermined path during vibration, avoiding the accumulation or scattering of the powder between the screen and the collecting hopper. The design of the guide plate optimizes the powder conveying path, reduces the resistance of the powder in the conveying process, and at the same time ensures the smoothness and accuracy of the screening process.

[0093] The mesh diameter of the top layer screen is the largest, mainly used for screening out the largest size of sorghum powder. The coarse particle powder after screening smoothly enters the top layer collecting hopper under the action of vibration through the guide plate. The top layer guide plate is installed between the top layer screen and the top layer collecting hopper, and the surface thereof is designed as a smooth inclined surface to reduce the resistance of the powder in the conveying process. The angle and length of the guide plate are optimized according to the vibration characteristics of the screen and the particle size of the powder, to ensure that the coarse particle powder can efficiently enter the collecting hopper. The mesh diameter of the middle layer screen is between the top layer and the bottom layer screen, responsible for further screening out the medium size of sorghum powder. The sorghum powder after the top layer screen falls into the middle layer screen, and the medium size powder smoothly enters the middle layer collecting hopper under the action of vibration through the middle layer guide plate. The design of the middle layer guide plate further optimizes the conveying path of the powder, to ensure that the medium size powder can efficiently enter the middle layer collecting hopper, avoiding the accumulation or scattering of the powder between the screen and the collecting hopper. The mesh diameter of the bottom layer screen is the smallest, mainly used for screening out the finest size of sorghum powder. The sorghum powder after the middle layer screen falls into the bottom layer screen, and the fine particle powder smoothly enters the bottom layer collecting hopper under the action of vibration through the bottom layer guide plate. The design of the bottom layer guide plate ensures the accurate collection of the fine particle powder, avoiding the flying and loss of the fine powder. The surface of the bottom layer guide plate is also designed as a smooth inclined surface to reduce the resistance of the powder in the conveying process, and its angle and length are optimized according to the characteristics of the fine powder.

[0094] By setting the guide plates between the top layer, middle layer and bottom layer screens and the corresponding collecting hoppers, the powder outlet assembly 33 of the utility model significantly improves the screening efficiency and collection accuracy of sorghum powder.
