Description

Technical Field

[0001] This utility model relates to the field of wheat vibrating screeners, specifically a screening device for wheat seed breeding. Background Technology

[0002] Wheat vibrating screens are important equipment used in the grain processing industry for cleaning and screening wheat. They use the reciprocating motion of the screen surface to make wheat grains move relative to each other, thereby achieving effective separation of large, small and light impurities. The equipment is usually composed of a feeding mechanism, screen body, vibrating mechanism and frame, and features small size, stable operation, good sealing and flexible adjustment.

[0003] Existing wheat vibrating screens use the principle of vibration to remove gravel, dust, and debris from wheat. However, a problem exists in actual use: the falling speed of the waste material is uncontrollable, making it difficult to adapt to various environments and usage requirements. Therefore, the inventors urgently need to design a screening mechanism that can adjust the falling speed of the waste material to improve the environmental adaptability of the screening device. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide a screening device for wheat seed breeding to solve the technical problem that the falling speed of waste is difficult to control, which limits its applicability under different environments and needs and affects production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening device for wheat seed breeding, comprising a screening machine body, a screening screen plate disposed on the lower inner side of the screening machine body, a receiving plate disposed on the lower side of the screening machine body, side plates disposed on both sides of the lower side of the screening machine body, one end of the receiving plate being rotatably connected to the screening machine body, and both sides of the receiving plate being fastened to the side plates through an adjustment mechanism to fix the angle position of the receiving plate.

[0006] By adopting the above technical solution, a basic framework for efficient screening has been constructed. The screening screen plate inside the main body of the screening machine can accurately separate materials of different particle sizes, while the rotating receiving plate below is fixedly connected to the side plate through the adjustment mechanism, realizing flexible adjustment of the waste falling angle. This not only enhances the adaptability of the equipment to different working conditions, but also reduces the difficulty of maintenance and improves the stability of operation through the modular structure.

[0007] Furthermore, the adjustment mechanism includes an adjustment groove, which is formed on the side plate and has a curved structure. A mounting seat is provided on the lower surface of the receiving plate at a position opposite to the adjustment groove.

[0008] By adopting the above technical solution, a larger range of motion trajectory is provided for the angle adjustment of the receiving plate. The adjustment groove on the side plate cooperates with the mounting seat on the lower surface of the receiving plate, so that the adjustment rod can move smoothly in the curved path, thereby realizing stepless adjustment of the tilt angle of the receiving plate. This not only enhances the flexibility of the waste falling speed control, but also reduces the jamming phenomenon in the adjustment process through the mechanical optimization of the curved structure.

[0009] Furthermore, an adjusting rod is movably inserted through the inner side of the mounting base. The two ends of the adjusting rod pass through the side plate via adjusting grooves and are fixed in position by a fastening handwheel.

[0010] By adopting the above technical solution, the angle of the receiving plate can be quickly locked and released. The operator only needs to rotate the fastening handwheel to adjust the position of the adjusting rod in the curved groove, thereby changing the tilt angle of the receiving plate, which significantly improves the convenience of equipment adjustment.

[0011] Furthermore, a intercepting gate is longitudinally slidably installed in the starting section of the screening machine body. Guide sleeves are fixedly installed on both sides of the intercepting gate. A guide rod is sleeved on the inner side of the guide sleeve. The guide rod is fixedly connected to the screening machine body. A nut is threaded onto the guide rod to limit the longitudinal position of the guide sleeve and the intercepting gate.

[0012] By adopting the above technical solution, precise interception and control of seed or waste flow rate is achieved. The guide rod is fixedly connected to the main body of the screening machine, and the guide sleeve is locked in position by a nut, so that the interception gate can be adjusted as needed in the initial section. This not only optimizes the flexibility of the screening process, but also avoids the leakage problem caused by gate displacement through physical limit.

[0013] Furthermore, several baffles are equidistantly installed above the vibrating screen section of the main body of the screening machine, and the baffles are inclined.

[0014] By adopting the above technical solution, the inclined structure effectively blocks the wheat seeds splashing during the screening process. The inclined setting of the baffle can reduce the seed loss rate and prevent wheat seeds from splashing to the outside of the screening machine.

[0015] Furthermore, the baffle is angled to deflect excessively high splashing wheat seeds.

[0016] By adopting the above technical solution, a semi-enclosed treatment of the screening area is constructed at the physical level to prevent seeds from splashing to the outside of the equipment due to vibration, thereby reducing material loss. Its inclined structure can block the seeds from sliding down the baffle surface to the screening screen.

[0017] Furthermore, a vibration motor is installed on the outer side of the side plate, and a drive mechanism is provided on one side of the main body of the screening machine, the drive mechanism being connected to the vibration motor in a transmission manner.

[0018] By adopting the above technical solution, a stable and controllable vibration source is provided for the main body of the screening machine. The vibration motor converts the rotational motion into high-frequency vibration through the drive mechanism, so that the screening screen plate generates the reciprocating motion required for efficient screening. This not only ensures the uniform transmission of vibration force, but also optimizes the vibration frequency and amplitude through the adjustment function of the drive mechanism to adapt to the screening needs of different seed characteristics.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention utilizes an adjustment mechanism to allow for stepless adjustment of the tilt angle of the receiving plate within a wide range. By changing the position of the adjustment rod in the adjustment groove, the sliding speed of the waste material along the plate surface can be flexibly adjusted to adapt to different working conditions. For example, when rapid discharge is required, the tilt angle can be increased to prevent waste accumulation; when dust control or precise separation is needed, the angle can be decreased to slow down the falling speed. This adjustment method directly affects the trajectory of the waste material, improving the environmental adaptability and screening efficiency of the equipment, simplifying the adjustment process, allowing operators to complete quick adjustments without the aid of tools, and ensuring reliable locking force, thus reducing maintenance frequency.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] This embodiment:

[0028] A screening device for wheat seed breeding, such as Figure 1-4 As shown, the system includes a screening machine body 1, a screening screen plate 2 located on the lower inner side of the screening machine body 1, a receiving plate 4 located below the screening machine body 1, and side plates 5 located on both sides of the lower bottom of the screening machine body 1. One end of the receiving plate 4 is rotatably connected to the screening machine body 1, and both sides of the receiving plate 4 are fastened to the side plates 5 through an adjustment mechanism 6 to fix the angle position of the receiving plate 4, thus constructing the basic framework for efficient screening. The screening screen plate 2 on the inner side of the screening machine body 1 can accurately separate materials of different particle sizes, while the rotating receiving plate 4 below is fastened to the side plates 5 through the adjustment mechanism 6, realizing flexible adjustment of the waste falling angle. This not only enhances the adaptability of the equipment to different working conditions, but also reduces maintenance difficulty and improves operational stability through the modular structure. At the same time, the synergistic effect of the rotating receiving plate 4 and the side plates 5 ensures continuous and efficient screening process, significantly improving the screening accuracy and operational efficiency of wheat seed breeding.

[0029] See Figure 1 , Figure 2 , Figure 4 The adjustment mechanism 6 includes an adjustment groove 601, which is located on the side plate 5 and has a curved structure. A mounting seat 602 is provided on the lower surface of the receiving plate 4, opposite to the adjustment groove 601, providing a larger range of motion trajectory for the angle adjustment of the receiving plate 4. The adjustment groove 601 on the side plate 5 cooperates with the mounting seat 602 on the lower surface of the receiving plate 4, allowing the adjustment rod 603 to move smoothly in the curved path, thereby realizing stepless adjustment of the tilt angle of the receiving plate 4. This not only enhances the flexibility of waste falling speed control, but also reduces the jamming phenomenon during the adjustment process through the mechanical optimization of the curved structure. At the same time, the precise alignment of the mounting seat 602 and the adjustment groove 601 ensures the structural stability of the adjustment mechanism 6 in a vibration environment, providing a reliable guarantee for the long-term operation of the equipment.

[0030] See Figure 1 , Figure 2 , Figure 4 An adjusting rod 603 is movably inserted through the inner side of the mounting base 602. Both ends of the adjusting rod 603 pass through the side plate 5 via the adjusting groove 601 and are fixed in position by the fastening handwheel 604. This enables quick locking and releasing of the angle of the receiving plate 4. The operator only needs to rotate the fastening handwheel 604 to adjust the position of the adjusting rod 603 in the curved groove, thereby changing the tilt angle of the receiving plate 4. This significantly improves the convenience of equipment adjustment. At the same time, this mechanical locking mechanism avoids the introduction of complex electronic components, reducing the failure rate. Furthermore, the setting of the fastening handwheel 604 can generate a large locking force, ensuring that the adjusted angle remains stable during vibration. This provides a precise and controllable waste flow guiding solution for different screening needs.

[0031] See Figure 1 , Figure 2 , Figure 3 The screening machine body 1 has a longitudinally sliding intercepting gate 3 installed in the starting section. Guide sleeves 8 are fixedly installed on both sides of the intercepting gate 3. Guide rods 7 are sleeved on the inner side of the guide sleeves 8. The guide rods 7 are fixedly connected to the screening machine body 1. Nuts are threaded on the guide rods 7 to limit the longitudinal position of the guide sleeves 8 and the intercepting gate 3, realizing precise interception control of seed or waste flow. The guide rods 7 are fixedly connected to the screening machine body 1, and the guide sleeves 8 are locked in position by nuts, so that the intercepting gate 3 can be adjusted as needed in the starting section. This not only optimizes the flexibility of the screening process, but also avoids the leakage problem caused by gate displacement through physical limit. At the same time, the longitudinal adjustment function of the intercepting gate 3 can adapt to the screening needs of different wheat varieties, reduce material waste, and cooperate with the screening screen 2 to achieve screening, significantly improving the versatility and processing efficiency of the equipment in different breeding scenarios.

[0032] See Figure 1 , Figure 2 Several baffles 9 are installed at equal intervals above the vibrating screen section of the main body 1 of the screening machine. The baffles 9 have an inclined structure, which effectively blocks the wheat seeds splashed during the screening process. The inclined setting of the baffles 9 can reduce the seed loss rate and prevent wheat seeds from splashing to the outside of the screening machine. At the same time, the baffles 9 arranged at equal intervals form a grid layer above the screening machine, which not only prevents seeds from splashing to the outside of the equipment and causing losses, but also prevents impurities from mixing into the seeds after screening, which significantly improves the screening purity. In addition, the baffles 9 are easy to disassemble and maintain, further enhancing the practicality of the equipment.

[0033] See Figure 1 , Figure 2 The baffle 9 has an inclined structure to block excessively splashed wheat seeds, creating a semi-enclosed treatment of the screening area at the physical level. This prevents seeds from splashing outside the equipment due to vibration, reducing material loss. Its inclined structure can also prevent seeds from sliding down the baffle surface to the screening screen 2. At the same time, the shielding effect of the baffle 9 reduces dust, improves the working environment, and reduces potential threats to the health of operators. Multiple optimizations are achieved through a simple structure, significantly improving the safety of the equipment and the screening quality.

[0034] See Figure 1 , Figure 2A vibration motor 10 is installed on the outer side of the side plate 5, and a drive mechanism 11 is provided on one side of the screening machine body 1. The drive mechanism 11 is connected to the vibration motor 10, providing a stable and controllable vibration source for the screening machine body 1. The vibration motor 10 converts the rotational motion into high-frequency vibration through the drive mechanism 11, so that the screening screen plate 2 generates the reciprocating motion required for efficient screening. This not only ensures the uniform transmission of vibration force, but also optimizes the vibration frequency and amplitude through the adjustment function of the drive mechanism 11, adapting to the screening requirements of different seed characteristics. At the same time, the external vibration motor 10 is easy to maintain and dissipate heat, extending the service life of the equipment and significantly improving the overall operational stability and energy efficiency.

[0035] The implementation principle of this embodiment is as follows: After the main body 1 of the screening machine is started, its built-in screening screen plate 2 generates high-frequency vibration under the drive of the vibrating motor 10, causing wheat seeds and impurities such as gravel and dust to move in layers under the action of vibration. Seeds that meet the particle size requirements continue to be conveyed through the screening screen plate 2, while impurities and debris fall to the rotatable and adjustable receiving plate 4 below. The adjusting rod 603 in the adjusting mechanism 6 slides in the arc-shaped adjusting groove 601 and is locked with the fastening handwheel 604, so the tilt angle of the receiving plate 4 can be precisely adjusted, thereby controlling the downward speed of the waste material along the plate surface and flexibly adapting to different working conditions. At the same time, the longitudinally adjustable intercepting gate 3 in the initial section is positioned by the guide rod 7 and the nut, which can intercept seeds or adjust the material flow as needed. Together with the inclined baffle 9 above the vibrating screen section, it effectively blocks seed splashing, ensuring that the screening process is stable and efficient. It realizes the fine control of the waste falling speed, seed interception amount and movement trajectory, and significantly improves the flexibility and environmental adaptability of the screening operation.
