Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed screening technology, specifically to a seed screening device for planting traditional Chinese medicinal herbs. Background Technology
[0002] Traditional Chinese medicine (TCM) mainly encompasses plant-based medicines (roots, stems, leaves, fruits, etc.), animal-based medicines (such as internal organs, skin, bones, and other tissues), and mineral-based medicines. Given that plant-based medicines constitute the largest proportion of TCM, it is often referred to as Chinese herbal medicines. In the cultivation of Chinese herbal medicines, seed selection is necessary to ensure a good germination rate.
[0003] A search revealed that patent application CN222568344U discloses a seed screening device for Chinese herbal medicine cultivation. While this device controls seed feeding by flipping and releasing a baffle plate to prevent excessive seed accumulation and improve screening quality, it has certain drawbacks. Chinese herbal medicine seeds often contain shriveled seeds with internal debris. Because shriveled seeds are similar in size to normal seeds, they cannot pass through the sieve mesh and are screened together with normal seeds. This results in an unsatisfactory screening effect with the existing device, necessitating further improvement. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a seed screening device for planting Chinese medicinal herbs, which solves the problems mentioned in the background art.
[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:
[0006] A seed screening device for planting Chinese medicinal herbs includes a screening box, wherein a sieve is installed inside the screening box;
[0007] The screening box is equipped with a feed pipe, an air separator is installed at one end of the inner wall of the screening box, an air collection hood is installed at the other end of the inner wall of the screening box, a first air pump is installed at one end of the outer surface of the screening box, and a processing box is installed at the other end of the outer surface of the screening box, with filter bags installed inside the processing box.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, a mounting plate is installed on the bottom end face of the screen, and a vibration motor is installed on the bottom end face of the mounting plate.
[0010] The beneficial effects of adopting the above-mentioned further solutions are:
[0011] The vibrating motor drives the screen to vibrate. When seeds enter the screening box from the feed pipe and fall onto the screen, the vibration causes the seeds to tumble and move continuously on the screen, preventing seed accumulation. At the same time, the vibration also allows smaller impurities and seeds that do not meet size requirements to fall through the screen mesh, ensuring the screening process is carried out effectively.
[0012] Furthermore, mounting blocks are installed at both ends of the feed pipe, and support frames are installed on the mounting blocks by bolts.
[0013] The beneficial effects of adopting the above-mentioned further solutions are:
[0014] The support frame is bolted to the mounting block, providing support for the feed pipe. This ensures the feed pipe remains in a fixed position as the seeds pass through it into the screening box.
[0015] Furthermore, the bottom surface of the inner wall of the screening box is provided with a first collection box and a second collection box. The first collection box is used to collect the screened seeds, and the second collection box is used to collect the seeds that do not meet the quality requirements after screening.
[0016] The beneficial effects of adopting the above-mentioned further solutions are:
[0017] By setting up a first collection box and a second collection box, seeds of different qualities after screening can be collected separately. After sieving and subsequent winnowing, seeds that meet the quality requirements fall into the first collection box, while seeds that do not meet the quality requirements, such as shriveled or damaged seeds and impurities, fall into the second collection box. This separate collection method facilitates the subsequent use of qualified seeds and the handling of unqualified seeds and impurities, improves work efficiency, and avoids seed mixing.
[0018] Furthermore, an air outlet pipe is installed on the first air pump, and the end of the air outlet pipe facing away from the first air pump is installed inside the air separator pipe.
[0019] The beneficial effects of adopting the above-mentioned further solutions are:
[0020] When the first air pump is working, it delivers air through the air outlet pipe into the air separator pipe. The air separator pipe blows airflow into the screening box, using the weight difference of the seeds for air separation. Heavier, plump seeds are less affected by the airflow and fall directly into the first collection box; while lighter, shriveled seeds, as well as dust and debris, are blown by the airflow. Heavier seeds or debris fall into the second collection box, while lighter impurities such as dust move towards the air collection hood, thus achieving further screening of the seeds and improving the quality of seed screening.
[0021] Furthermore, a second air pump is installed on the processing box, and the second air pump is connected to the gas in the processing box through an air inlet pipe.
[0022] The beneficial effects of adopting the above-mentioned further solutions are:
[0023] The second air pump is connected to the processing chamber via an air inlet pipe, creating negative pressure inside the chamber. When air containing dust and debris generated during the air separation process is blown towards the collection hood, the negative pressure generated by the second air pump forces this air into the processing chamber through an extraction pipe. This ensures that dust and debris generated during the screening process are collected in the processing chamber in a timely manner, preventing dust and debris from flying around inside the screening chamber, reducing environmental pollution, and improving the working environment for operators.
[0024] Furthermore, an extraction tube is embedded and fixed on the side end face of the processing box, and the end of the extraction tube opposite to the processing box is embedded and fixed inside the gas collection hood.
[0025] The beneficial effects of adopting the above-mentioned further solutions are:
[0026] The extraction pipe connects the air collection hood and the treatment box. Under the action of the second air pump, the air collection hood can effectively collect the air containing dust and debris generated during the air separation process and transport it to the treatment box through the extraction pipe. The filter bags in the treatment box can filter the dust and debris, allowing the purified air to be discharged. This achieves effective collection and treatment of dust and debris generated during the screening process, ensuring the environmental performance of the screening device.
[0027] This invention provides a seed screening device for planting traditional Chinese medicinal herbs. It has the following beneficial effects:
[0028] The first and second collection boxes, located on the bottom surface of the inner wall of the screening box, allow for the separate collection of seeds of different qualities after screening. Seeds that meet the quality requirements fall into the first collection box, while seeds that do not meet the quality requirements, as well as impurities, fall into the second collection box. This facilitates the subsequent use of qualified seeds and the handling of unqualified seeds and impurities, improves work efficiency, and avoids seed mixing.
[0029] The first air pump delivers air into the air separator pipe through the air outlet pipe. The air separator pipe blows airflow into the screening box, using the weight difference of the seeds for air separation. Heavier, plump seeds are less affected by the airflow and fall directly into the first collection box. Lighter, shriveled seeds, along with dust and debris, are blown by the airflow. Heavier seeds fall into the second collection box, while lighter impurities such as dust move towards the air collection hood, achieving further screening of the seeds and improving the quality of seed screening.
[0030] The second air pump installed on the processing box is connected to the processing box through the air inlet pipe, which creates negative pressure inside the processing box. This allows the air containing dust and debris generated during the air separation process to be collected into the processing box through the extraction pipe in a timely manner, preventing dust and debris from flying around inside the screening box, reducing environmental pollution, and improving the working environment for operators.
[0031] The extraction pipe connects the air collection hood and the treatment box. Under the action of the second air pump, the air collection hood can effectively collect the dust-laden air generated by the air separation and transport it to the treatment box. The filter bags in the treatment box filter the dust and debris, and the purified air is discharged. This achieves effective collection and treatment of dust and debris generated during the screening process, ensuring the environmental performance of the screening device. Attached Figure Description

Detailed Implementation
[0041] 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.
[0042] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:
[0043] Example 1
[0044] A seed screening device for planting Chinese herbal medicines includes a screening box 1, and a screen 103 is installed inside the screening box 1;
[0045] The screening box 1 is equipped with a feed pipe 2, an air separator pipe 104 is installed at one end of the inner wall of the screening box 1, an air collection hood 107 is installed at the other end of the inner wall of the screening box 1, a first air pump 101 is installed at one end of the outer surface of the screening box 1, and a processing box 3 is installed at the other end of the outer surface of the screening box 1. A filter bag 304 is installed inside the processing box 3.
[0046] A mounting plate 108 is installed on the bottom surface of the screen 103, and a vibration motor 109 is installed on the bottom surface of the mounting plate 108. The vibration motor 109 can drive the screen 103 to vibrate. When seeds enter the screening box 1 from the feed pipe 2 and fall onto the screen 103, the vibration of the screen 103 can cause the seeds to continuously roll and move on the screen 103, preventing seed accumulation. At the same time, the vibration can also cause smaller impurities and seeds that do not meet the size requirements to fall through the mesh of the screen 103, ensuring the screening process.
[0047] Both ends of the feed pipe 2 are equipped with mounting blocks 201. Support frames 202 are bolted to the mounting blocks 201, and the support frames 202 are bolted to the mounting blocks 201, providing support for the feed pipe 2. This ensures that the position of the feed pipe 2 remains fixed during the process of seeds entering the screening box 1 through the feed pipe 2.
[0048] The bottom inner wall of the screening box 1 is equipped with a first collection box 105 and a second collection box 106. The first collection box 105 is used to collect the screened seeds, and the second collection box 106 is used to collect the seeds that do not meet the quality requirements after screening. By setting up the first collection box 105 and the second collection box 106, the seeds of different qualities after screening can be collected separately. After screening by the sieve 103 and subsequent air separation processes, the seeds that meet the quality requirements will fall into the first collection box 105, while the seeds that do not meet the quality requirements, such as shriveled, broken seeds and impurities, will fall into the second collection box 106. This separate collection method facilitates the subsequent use of qualified seeds and the handling of unqualified seeds and impurities, improves work efficiency, and avoids seed mixing.
[0049] Example 2
[0050] To wind-separate the lighter, shriveled seeds and to wind-separate and collect the resulting dust and debris, for example, such as Figures 1 to 5 As shown, this utility model also includes:
[0051] An air outlet pipe 102 is installed on the first air pump 101. The end of the air outlet pipe 102 facing away from the first air pump 101 is installed inside the air separator pipe 104. When the first air pump 101 is working, it delivers air to the air separator pipe 104 through the air outlet pipe 102. The air separator pipe 104 blows airflow into the screening box 1, using the weight difference of the seeds for air separation. Heavier, plump seeds are less affected by the airflow and fall directly into the first collection box 105; while lighter, shriveled seeds, as well as dust and debris, are blown by the airflow. Heavier seeds or debris fall into the second collection box 106, while lighter impurities such as dust move towards the air collection hood 107, thereby achieving further screening of the seeds and improving the quality of seed screening.
[0052] A second air pump 302 is installed on the processing box 3. The second air pump 302 is connected to the processing box 3 via an air inlet pipe 303, and can create negative pressure inside the processing box 3. When the air containing dust and debris generated during the air separation process is blown towards the air collection hood 107, under the negative pressure generated by the second air pump 302, this air will enter the processing box 3 through the extraction pipe 301. This ensures that the dust and debris generated during the screening process can be collected in the processing box 3 in a timely manner, preventing dust and debris from flying in the screening box 1, reducing environmental pollution, and also improving the working environment of the operators.
[0053] An extraction pipe 301 is embedded and fixed on the side end face of the processing box 3. The end of the extraction pipe 301 opposite to the processing box 3 is embedded and fixed inside the air collection hood 107. The extraction pipe 301 connects the air collection hood 107 and the processing box 3. Under the action of the second air pump 302, the air collection hood 107 can effectively collect the air containing dust and debris generated during the air separation process and transport it into the processing box 3 through the extraction pipe 301. The filter bag 304 inside the processing box 3 can filter the dust and debris, allowing the purified air to be discharged. This achieves effective collection and treatment of dust and debris generated during the screening process, ensuring the environmental performance of the screening device.
[0054] Working principle:
[0055] Seed feeding: Seeds enter the screening box 1 through the feed pipe 2. The support brackets 202, which are bolted to the mounting blocks 201 at both ends of the feed pipe 2, ensure that the position of the feed pipe 2 is fixed, so that the seeds can enter the screening box 1 stably.
[0056] Vibration screening: Seeds fall onto screen 103, and a vibration motor 109 mounted on the bottom surface of screen 103 drives screen 103 to vibrate. Vibration causes the seeds to tumble and move continuously on screen 103, preventing seed accumulation. At the same time, smaller impurities and seeds that do not meet the size requirements fall through the mesh of screen 103 into the collection area below.
[0057] Initial collection: The bottom inner wall of the screening box 1 is provided with a first collection box 105 and a second collection box 106. After being screened by the sieve 103, larger seeds that meet the size requirements remain on the sieve 103 for further screening, smaller seeds that do not meet the quality requirements and some impurities fall into the second collection box 106, while seeds that meet certain quality requirements remain on the sieve 103 to await further screening.
[0058] Air separation process: The first air pump 101 operates, delivering air through the air outlet pipe 102 to the air separation pipe 104. The air separation pipe 104 blows airflow into the screening box 1, utilizing the weight difference of the seeds for air separation. Heavier, plump seeds are less affected by the airflow and fall directly into the first collection box 105; while lighter, shriveled seeds, as well as dust and debris, are blown by the airflow. Heavier seeds or debris fall into the second collection box 106, while lighter impurities such as dust move towards the air collection hood 107.
[0059] Dust and debris collection: The second air pump 302 on the processing chamber 3 is connected to the gas in the processing chamber 3 through the air inlet pipe 303, creating a negative pressure inside the processing chamber 3. The air containing dust and debris generated during the air separation process is blown toward the air collection hood 107, and under the action of the negative pressure generated by the second air pump 302, this air enters the processing chamber 3 through the extraction pipe 301.
[0060] Filtration and purification: The filter bag 304 installed inside the processing chamber 3 filters the air entering the processing chamber 3, trapping dust and debris inside and allowing the purified air to be discharged, thus effectively treating the dust and debris generated during the screening process. Finally, the first collection chamber 105 collects seeds that meet the quality requirements, and the second collection chamber 106 collects seeds that do not meet the quality requirements and some impurities, completing the entire seed screening process.
