Abstract
Description
Technical Field
[0001] The invention relates to the technical field of crop processing devices, in particular to a multifunctional vibrating screen for preparing crop seeds. Background Art
[0002] Screening is a crucial step in the production of crop seeds. Although traditional vibrating screens can screen seeds to a certain extent, they have many problems and limitations.
[0003] First, the screening efficiency of traditional vibrating screens is often not high enough. Due to the single screen design, the movement path of the seeds on the screen is limited, and there are insufficient collision opportunities, which leads to a long screening process and inaccurate screening results. This not only affects production efficiency, but also may lead to uneven seed quality. Secondly, traditional vibrating screens are prone to clogging. During the screening process, seeds are often tightly accumulated on the screen due to gravity, forming a layer that is difficult to penetrate, causing the screen to be blocked and affecting the screening effect. At the same time, blockage may also cause equipment failure and increase maintenance costs. In addition, traditional vibrating screens also have difficulties in handling agglomerated seeds. During the seed processing process, sometimes multiple seeds stick together tightly to form agglomerates. These agglomerated seeds are difficult to be effectively broken up on traditional vibrating screens, affecting the efficiency and accuracy of screening.
[0004] In summary, the traditional vibrating screen has problems such as low screening efficiency, easy clogging, and difficulty in handling agglomerated seeds in the process of crop seed production. These problems not only affect production efficiency, but may also lead to a decline in seed quality, bringing adverse effects to crop planting. Summary of the invention
[0005] The invention provides a multifunctional vibrating screen for crop seed production, aiming to solve the problems of low screening efficiency, easy clogging, difficulty in processing agglomerated seeds, etc. existing in the traditional vibrating screen in the crop seed production process.
[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a multifunctional vibrating screen for crop seed production, comprising an equipment frame, on which an upper screen frame and a hopper are arranged in order from high to low, and a discharge port is arranged on the hopper; The four corners of the upper screen frame are installed on the equipment frame through spring support columns, a vibration motor is provided on one side of the upper screen frame, and an upper screen is provided on the inner bottom of the upper screen frame, and the upper screen is directly facing the hopper; A plurality of partitions are arranged in rows and at equal distances on the inner side of the upper screen frame. The partitions are of equal height and parallel to each other, and are inclined in the same direction.
[0007] In some embodiments, the upper screen frame is tilted, the vibration motor is arranged on a higher side of the upper screen frame, the other side of the upper screen frame is an open side, and the open side is provided with a guide groove.
[0008] In some embodiments, a baffle is detachably provided on the opening side.
[0009] In some embodiments, a lower screen frame is provided between the upper screen frame and the hopper, a lower screen is provided in the lower screen frame, and the mesh number of the lower screen is greater than the mesh number of the upper screen.
[0010] In some embodiments, the four corners of the lower screen frame are all set on the equipment frame through elastic telescopic columns, and the telescopic direction of the elastic telescopic columns is lateral telescopic.
[0011] In some embodiments, a transmission rod is connected between the lower screen frame and the vibration motor.
[0012] Compared with the prior art, the present invention has the following beneficial effects: The upper screen frame of the present invention is installed on the equipment frame through spring support columns, and can generate stable and efficient vibrations in conjunction with the use of a vibration motor. This design ensures that the seeds can be quickly dispersed and layered on the upper screen, and after multiple vibrations and collisions, efficient and accurate screening is achieved. Compared with traditional vibrating screens, the screening efficiency of the present invention is significantly improved, and the screening accuracy is also guaranteed, and seeds that meet the requirements can be accurately separated from impurities and unqualified seeds.
[0013] The partitions arranged in rows at equal distances on the inner side of the upper screen frame of the present invention not only increase the movement path and collision chance of the seeds, but also effectively avoid the accumulation and clogging of seeds on the screen through their inclined design. The presence of the partitions forces the seeds to bypass or slide along the partitions, reducing the local accumulation of seeds on the screen, thereby reducing the risk of clogging. At the same time, the inclined design of the partitions and the combined effect of the vibration motor significantly reduce the mechanical damage to the seeds during the screening process, thereby ensuring the integrity of the seeds.
[0014] The angle formed between the partition and the upper screen of the present invention, as well as the vibration generated by the vibration motor, act together on the agglomerated seeds, causing them to be subjected to shear force and broken into individual seeds. This design effectively solves the problem that traditional vibrating screens are difficult to handle agglomerated seeds, and improves the uniformity and efficiency of screening.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] like Figure 1-4As shown, this embodiment provides a multifunctional vibrating screen for crop seed production, including an equipment frame 1, on which an upper screen frame 2 and a hopper 4 are arranged in order from high to low, and the hopper 4 is provided with a discharge port 401; The four corners of the upper screen frame 2 are installed on the equipment frame 1 through spring support columns 206. A vibration motor 205 is provided on one side of the upper screen frame 2. An upper screen 201 is provided on the inner bottom of the upper screen frame 2. The upper screen 201 faces the hopper 4. The upper screen frame 2 is installed on the equipment frame 1 through the spring support columns 206. With the use of the vibration motor 205, stable and efficient vibration can be generated, so that the seeds are quickly dispersed and layered on the upper screen 201, thereby achieving efficient screening; Several partitions 202 are arranged in rows at equal distances on the inner side of the upper screen frame 2. Each partition 202 is of equal height and parallel to each other, and each partition 202 is inclined in the same direction. The partitions 202 are spaced apart from the upper screen 201. The partitions 202 arranged in rows at equal distances in the upper screen frame 2 not only increase the movement path and collision opportunities of the seeds, promote the effective separation of the seeds, but also reduce the accumulation and blockage of the seeds on the screen. The partitions 202 are of equal height and parallel to each other, and are inclined in the same direction. This design helps to guide the seeds to flow smoothly and avoid mechanical damage caused by excessive local pressure. Specifically, the partitions 202 are arranged on the inner side of the upper screen frame 2, and are of equal height, parallel to each other and inclined. When the seeds fall from the hopper 4 into the upper screen 201, they may originally slide along a relatively direct path. However, the presence of the partition 202 forces the seeds to change their flow direction, so that they have to bypass the partition 202 or slide along the inclined surface of the partition 202. This process of changing the flow direction increases the length of the movement path of the seeds, and when the seeds come into contact with the inclined partition 202, they may jump up or even roll in the air due to the inclination angle and vibration of the partition 202. This jumping and rolling not only increases the chance of collision between seeds, but also gives the seeds a chance to fall again to different positions of the upper screen 201, thereby further promoting the screening process, and the presence of the partition 202 reduces the accumulation of seeds on the upper screen 201. In the absence of the partition 202, the seeds may be closely piled together due to gravity to form a layer that is difficult to penetrate. The partition 202 divides the upper screen 201 into multiple smaller areas, and the number of seeds in each area is relatively small, reducing the possibility of accumulation and blockage.
[0022] In addition, since the partitions 202 are arranged at an angle, an angle is formed between them and the upper screen 201. When the seeds fall into this angle, under the action of the vibration motor 205, the seeds will vibrate up and down along this angle. This up and down vibration not only increases the chance of collision between seeds, but also promotes the uniform distribution of seeds on the upper screen 201, and in the seed processing process, agglomeration sometimes occurs, that is, multiple seeds are tightly adhered together. When these agglomerated seeds fall into the angle between the partition 202 and the upper screen 201, the up and down vibration effect will be applied to different parts of the agglomerated seeds, thereby generating shear force. This shear force helps to break up the agglomerated seeds into individual seeds, improves the efficiency and accuracy of screening, and the seeds in the angle will continuously contact the upper screen 201 and the partition 202 during the up and down vibration process. This contact not only helps to screen out impurities and unqualified seeds from the sieve holes, but also allows the seeds that meet the requirements to be more purely retained on the upper screen 201 or fall into the collection container below. Therefore, the inclined setting of the partition 202 and the up and down vibration of the seeds within the angle together enhance the screening effect. In the absence of the partition 202, the vibration motor 205 may cause some seeds to splash out from the screen, causing waste and pollution. The existence of the partition 202 acts as a "fence", limiting the seeds within the angle and preventing the seeds from splashing around. At the same time, the partition 202 can also guide the seeds to move along a specific path, further improving the controllability and efficiency of screening.
[0023] The working principle of the present invention is as follows: First, pour the mixed seeds into the upper inlet of the vibrating screen. The vibrating screen consists of an upper screen frame 2, an upper screen 201, a partition 202, a spring support column 206, a vibration motor 205, and a hopper 4 arranged at the bottom. The upper screen frame 2 is installed on the equipment frame 1 through the spring support column 206, and the vibration motor 205 is fixed to the side or bottom of the upper screen frame 2 to generate vibration.
[0024] When the vibration motor 205 is started, the vibration generated by it is transmitted to the upper screen frame 2 through the spring support column 206, so that the upper screen frame 2 and the upper screen 201 and the partition 202 thereon generate stable and efficient vibration. The mixed seeds are vibrated on the upper screen 201 and begin to jump, roll and collide.
[0025] The partitions 202 are equidistant, parallel and inclinedly arranged on the inner side of the upper screen frame 2, which changes the flow direction of the seeds, so that the seeds have to bypass the partitions 202 or slide along the inclined surface of the partitions 202. This design increases the movement path and collision opportunities of the seeds, and promotes the effective separation of the seeds. At the same time, the angle formed between the partitions 202 and the upper screen 201 and the effect of vibration make the seeds in the angle vibrate up and down, accelerate the dispersion of agglomerated seeds, and avoid the accumulation and blockage of seeds.
[0026] After multiple vibrations and screening, the seeds that meet the requirements fall into the hopper 4 below through the mesh of the upper screen 201. The hopper 4 is arranged at the bottom of the vibrating screen to receive the seeds that have been screened. The impurities and unqualified seeds are left on the upper screen 201 or discharged in other ways. The entire screening process is efficient, accurate, and causes little damage to the seeds, meeting the high standards for the production of crop seeds.
[0027] In summary, the multifunctional vibrating screen for crop seed production provided by the present invention solves the problems existing in traditional vibrating screens through a series of innovative designs, achieves efficient and accurate screening effects, and has multiple technical effects such as reducing blockage, mechanical damage, processing agglomerated seeds, and avoiding seed splashing.
[0028] In some embodiments, Figure 1 and Figure 2 As shown, the upper screen frame 2 is tilted, and the vibration motor 205 is arranged on the higher side of the upper screen frame 2. The other side of the upper screen frame 2 is an open side, and the open side is provided with a guide groove 204; the tilted design of the upper screen frame 2 allows the sieved seeds to naturally slide along the inclined surface into the guide groove 204 by gravity, thereby facilitating the collection and subsequent processing of the seeds. Since the seeds can slide smoothly into the guide groove 204, accumulation or retention on the screen is avoided, thereby ensuring the continuity and stability of the screening process. This helps to reduce the frequency of shutdown for cleaning and improve the overall screening efficiency.
[0029] In some embodiments, Figure 2 As shown, a baffle 203 is detachably provided on the opening side, and the baffle 203 can be flexibly installed or disassembled as needed to control the opening size of the opening side, thereby adjusting the discharge speed and flow rate of the seeds. When a large amount of seeds need to be discharged quickly, the baffle 203 can be completely or partially removed so that the seeds can slide smoothly along the guide groove 204; and when the discharge speed needs to be slowed down or fine screening needs to be performed, the baffle 203 can be installed in place, and the discharge amount of the seeds can be controlled by adjusting the gap between the baffle 203 and the upper screen frame 2. The presence of the baffle 203 allows the user to control the discharge process of the seeds more finely. By adjusting the gap between the baffle 203 and the upper screen frame 2, the discharge amount of the seeds can be fine-tuned, thereby achieving a more accurate screening effect. This is especially important for crop seeds that require high-precision screening.
[0030] In some embodiments, Figure 1 and Figure 3As shown, a lower screen frame 3 is provided between the upper screen frame 2 and the hopper 4, and a lower screen 301 is provided in the lower screen frame 3, and the mesh number of the lower screen 301 is greater than the mesh number of the upper screen 201; this design enables the vibrating screen to have a double-layer screening function, the upper screen 201 is mainly used for preliminary screening, and larger impurities and unqualified seeds are screened out, while the lower screen 301 performs more refined screening to ensure that the final seeds are of high purity and good quality. The mesh number of the lower screen 301 is greater than that of the upper screen 201, which means that its sieve hole is smaller and can more effectively intercept fine impurities and unqualified seeds. Through the design of double-layer screening, the present invention makes full use of the space and performance of the vibrating screen. The coordinated use of the upper screen frame 2 and the lower screen frame 3 enables the equipment to process more seeds in the same processing time, thereby improving the utilization rate and production efficiency of the equipment.
[0031] In some embodiments, Figure 3 As shown, the four corners of the lower screen frame 3 are all set on the equipment frame 1 through elastic telescopic columns 302, and the telescopic direction of the elastic telescopic columns 302 is lateral telescopic, and the telescopic amplitude and frequency of the elastic telescopic columns 302 can be adaptively adjusted according to the impact force generated by the seed falling; when the seeds fall into the lower screen frame 3 from above, the impact force generated will drive the elastic telescopic columns 302 to telescope laterally, thereby driving the lower screen frame 3 to produce horizontal and lateral reciprocating motion. This movement increases the movement path and collision opportunities of the seeds on the screen, so that the seeds can be dispersed and layered faster and fall through the sieve holes. Therefore, this design significantly accelerates the screening process and improves the screening efficiency. The reciprocating elastic activity of the lower screen frame 3 allows the seeds to be screened more evenly and fully on the screen. The continuous rolling and collision of the seeds on the screen helps to break the agglomeration, making it easier for impurities and unqualified seeds to be screened out. At the same time, this activity also reduces the accumulation and clogging of seeds on the screen, further improving the accuracy and purity of the screening.
[0032] In some embodiments, Figure 3As shown, a transmission rod 303 is connected between the lower screen frame 3 and the vibration motor 205, and the transmission rod 303 can transmit and enhance the vibration force generated by the vibration motor 205, so that the lower screen frame 3 can perform a more stable and powerful lateral reciprocating motion under the support of the elastic telescopic column 302; the direct connection of the transmission rod 303 ensures that the vibration force generated by the vibration motor 205 can be efficiently and losslessly transmitted to the lower screen frame 3. This design reduces the attenuation of vibration during the transmission process, so that the lower screen frame 3 can receive a stronger and more stable vibration signal, thereby improving the efficiency and effect of screening. Since the transmission rod 303 enhances the transmission of vibration force, the lower screen frame 3 can perform a more powerful and uniform lateral reciprocating motion during the screening process. This movement increases the collision and rolling frequency of seeds on the screen, and promotes the rapid dispersion and stratification of seeds. At the same time, it also helps to break the agglomeration of seeds, making it easier to screen out impurities and unqualified seeds. These factors together improve the efficiency and accuracy of screening and ensure the purity and quality of the final product.
[0033] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
