Description

Technical Field

[0001] This utility model relates to the field of breeding and screening technology, and in particular to a breeding and screening device for Trichosanthes kirilowii seeds. Background Technology

[0002] For crops like Trichosanthes kirilowii seeds that require seed cultivation, seed selection is necessary before planting to ensure a good harvest and quality. Traditional screening equipment mainly uses screen vibration or simple up-and-down or left-and-right shaking to remove unqualified small seeds. This screening method is quite effective when processing small quantities of Trichosanthes kirilowii seeds, but due to the limited screening area, it is difficult to provide sufficient screening effect in large-scale production. When processing a large number of seeds, the seeds tend to accumulate, causing some seeds to remain in the same position, resulting in the upper layer of seeds not being fully screened, affecting the thoroughness and efficiency of the screening. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a Trichosanthes kirilowii seed breeding and screening device, which solves the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a Trichosanthes kirilowii seed breeding and screening device, including a material holding box, on both sides of the inside of the material holding box, brackets are fixedly installed, connecting shafts are rotatably installed on the upper ends of the two brackets, a sieve frame is fixedly connected between the two connecting shafts, the top and bottom of the sieve frame are provided with arrayed sieve holes, the inside of the sieve frame is provided with a clearing mechanism for clearing the sieve holes, and one of the brackets is provided with a screening mechanism for driving the sieve frame to swing up and down.

[0005] Furthermore, the screening mechanism includes an electric telescopic rod fixedly installed on one side of the support and a rotating frame fixedly sleeved on the end of the connecting shaft. Guide columns are fixedly connected to both ends of the rotating frame. A support is fixedly connected to the free end of the electric telescopic rod. The support is slidably installed on the side of the support, and a guide frame is slidably inserted into one side of the support. The end of one of the guide columns is movably inserted into the guide frame. A connecting spring is fixedly installed between the guide frame and the material container.

[0006] Furthermore, the unblocking mechanism includes a flap that is movably disposed on the inner wall of the screen frame. Multiple unblocking rods corresponding to the screen holes are fixedly connected to the side of the flap, and a steering component is provided at each of the four corners of the flap.

[0007] Furthermore, the steering component includes a movable rod movably inserted into the end of the bracket, the end of the movable rod being fixedly connected to a rotating shaft via a connecting plate, and the end of the flap having an insertion hole for the rotating shaft to be inserted.

[0008] Furthermore, a telescopic spring is sleeved on the outside of the movable rod, and the two ends of the telescopic spring are respectively fixedly installed on the connecting plate and the screen frame.

[0013] 2. This utility model has screen holes at both the top and bottom of the screen frame, and the screen holes on both sides can be used alternately, which reduces the risk of clogging and ensures the continuity of screening operations.

[0014] 3. This utility model, by setting a flap and providing a turning component at each of the four corners of the flap, can adjust the flipping direction of the flap, so that the flap can clear the double-sided sieve holes and ensure the screening effect of the sieve plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Traditional screening equipment mainly uses the vibration of the screen or simple up-and-down or left-and-right shaking to screen out unqualified small seeds. This screening method is quite effective when processing a small number of Trichosanthes kirilowii seeds, but due to the limited screening area, it is difficult to provide sufficient screening effect in large-scale production. When processing a large number of seeds, the seeds are prone to pile up, causing some seeds to be unable to move, resulting in the upper layer of seeds not being fully screened, affecting the thoroughness and efficiency of screening.

[0023] Example 1

[0024] To address the shortcomings of the aforementioned screening equipment during use, please refer to [link / reference needed]. Figures 1-4The present invention provides a Trichosanthes kirilowii seed breeding and screening device, which enables more thorough seed screening and is suitable for screening large quantities of seeds. This screening equipment uses a material container 1 as its base. Supports 2 are fixedly installed on both sides of the container 1. Connecting shafts 3 are rotatably mounted on the upper ends of both supports 2. A screen frame 4 is fixedly connected between the two connecting shafts 3. The top and bottom of the screen frame 4 have arrayed screen holes 401. A screening mechanism 6 is installed on one of the supports 2 to drive the screen frame 4 to swing up and down. Door panels 7 are detachably installed on both ends of the screen frame 4. Opening the door panels 7 allows the seeds to be screened to be added into the screen frame 4. Closing the door panels 7 then drives the screening mechanism 6 to rotate the connecting shafts 3 back and forth. This rotation causes the screen frame 4 to swing up and down, causing the seeds to roll back and forth, continuously adjusting the position of the seeds within the screen frame 4. This ensures that unqualified small seeds fall completely through the screen holes 401, leaving qualified seeds inside the screen frame 4. Compared to traditional simple vibration methods, this screening equipment avoids seed accumulation, provides more thorough seed screening, and is more suitable for screening large quantities of seeds.

[0025] To achieve the effect of the screening mechanism 6 on the screen frame 4, an electric telescopic rod 601 is fixedly installed on one side of the support 2, and a rotating frame 602 is fixedly sleeved on the end of the connecting shaft 3. Guide columns 603 are fixedly connected to both ends of the rotating frame 602. A support 604 is fixedly connected to the free end of the electric telescopic rod 601. The support 604 is slidably installed on the side of the support 2, and a guide frame 605 is slidably inserted into one side of the support 604. The end of one of the guide columns 603 is movably inserted into the guide frame 605. A connecting spring 606 is fixedly installed between the guide frame 605 and the material box 1. Driving the electric telescopic rod 601 can drive the support 604 to slide back and forth. The support 604 reciprocates and slides, which can drive the connecting shaft 3 to reciprocate and rotate through the guide frame 605 and the guide column 603, thereby realizing the up and down swing of the sieve frame 4. When the sieve hole 401 at the bottom is blocked, the guide frame 605 can be pulled outward to separate it from the guide column 603. At this time, the connecting spring 606 deforms, and the sieve frame 4 is reversed, flipping the sieve hole 401 at the top to the bottom. After the guide frame 605 is released, it can be reset by the elastic force of the connecting spring 606. The other guide column 603 can enter the guide frame 605. By continuing to drive the electric telescopic rod 601, the sieve hole 401 on the other side can be used to screen the seeds, ensuring the continuity of the screening operation.

[0026] To collect the screened seeds, the inner bottom wall of the holding box 1 is provided with a ramp 101, and the bottom of the side wall of the holding box 1 is provided with a discharge port 102. When the sieve frame 4 is screening, unqualified seeds can slide down the ramp 101 and out of the discharge port 102. After screening, all unqualified seeds have been discharged. Then, the door panel 7 is opened and the electric telescopic rod 601 is driven to tilt the sieve frame 4. Qualified seeds can fall onto the ramp 101 and slide down the discharge port 102. In this way, qualified and unqualified seeds can be discharged in batches, which is convenient for staff to collect.

[0027] Example 2

[0028] After prolonged use, some seeds may inevitably become stuck in the sieve holes 401. To facilitate unclogging the sieve holes 401, please refer to... Figure 3 and Figure 4 As shown, both sides of the inside of the screen frame 4 are provided with a clearing mechanism 5 for clearing the screen holes 401. The clearing mechanism 5 includes a flap 501 movably disposed on the inner wall of the screen frame 4. Multiple clearing rods 502 corresponding to the screen holes 401 are fixedly connected to the side of the flap 501. Each of the four corners of the flap 501 is provided with a turning component 503. The four sets of turning components 503 are paired up to adjust the flipping direction of the flap 501. When the flap 501 flips upward, it drives the clearing rods 502 into the screen holes 401 at the top of the screen frame 4 to clear the screen holes 401 at the top of the screen frame 4. Similarly, when the flap 501 flips downward, it can clear the screen holes 401 at the bottom of the screen frame 4.

[0029] Specifically, the steering component 503 includes a movable rod 5031 movably inserted into the end of the bracket 2. The end of the movable rod 5031 is fixedly connected to a rotating shaft 5033 via a connecting plate 5032. The end of the flip plate 501 has an insertion hole 5034 for the rotating shaft 5033 to be inserted. A telescopic spring 5035 is sleeved on the outside of the movable rod 5031. Both ends of the telescopic spring 5035 are fixedly installed on the connecting plate 5032 and the screen frame 4, respectively. During screening, all four rotating shafts 5033 are inserted into their corresponding insertion holes 5034 by the elastic force of the telescopic springs 5035. The rotating shafts 5033 can rotate the flip plate... The plate 501 is fixed to the side of the sieve frame 4 and does not affect the screening operation of the sieve frame 4. When it is necessary to clean the sieve holes 401 at the top of the sieve frame 4, pull the two rotating shafts 5033 at the bottom of the flip plate 501 to slide out from the insertion hole 5034 and flip the flip plate 501 upward. The unblocking rod 502 can push out the seeds stuck in the sieve holes 401 to unblock the sieve holes 401. Similarly, when it is necessary to clean the sieve holes 401 at the bottom of the sieve frame 4, simply pull the two rotating shafts 5033 at the top of the flip plate 501. The operation is convenient and can unblock the sieve holes 401 on both sides of the sieve frame 4 to ensure the screening effect of the sieve frame 4.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
