Description

Technical Field

[0001] The utility model relates to a device for cleaning and selecting flat-stalked sedge seeds, belonging to the technical field of seed screening. Background Art

[0002] Scirpus flatulosus has extremely important ecological value. It is a key food source plant for rare birds such as the Siberian Crane and the Oriental White Stork. Its research and protection value is extremely high. At present, a large number of Scirpus flatulosus ecological restoration projects have been carried out. The use of Scirpus flatulosus seeds for efficient sexual reproduction is crucial in the restoration work, and seed cleaning is a key link. Therefore, high-quality cleaning of Scirpus flatulosus seeds is of great significance for the restoration of Scirpus flatulosus and the protection of rare birds.

[0003] At present, the seed cleaning of flat-stemmed sedge faces many difficulties. Under the traditional manual cleaning mode, after the seeds are roughly processed and threshed, they are often attached with scales and soft hairs that are difficult to clean. On the one hand, the efficiency of manual cleaning is extremely low, and the staff needs to invest a lot of time and energy in repetitive operations, which seriously affects the progress of the work and the labor cost is also high; on the other hand, even after screening, there will still be a lot of scales and soft hairs remaining. In addition, although wind cleaning has a certain effect, the residue problem is still prominent; electrostatic cleaning is inefficient and slow, and it is difficult to meet the requirements of efficient cleaning. These traditional cleaning methods show obvious shortcomings in the cleaning of flat-stemmed sedge seeds. The removal rate of scales and soft hairs and the seed cleaning rate are both low, and it is impossible to separate seeds of different particle sizes, and it is impossible to achieve the goal of efficient and accurate cleaning.

[0004] With the increasing attention paid to the resources of flat-stemmed Scirpus and the increasingly stringent requirements for seed cleaning quality, a new type of flat-stemmed Scirpus seed cleaner is urgently needed to change the status quo. Especially considering the key position of flat-stemmed Scirpus as an important food source for rare birds, it is very important to effectively protect and study it. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] A device for cleaning and selecting flat-stalked sedge seeds comprises a wind separation box body 1, a screening frame 2, first to fourth screens and a first waste box 7, wherein the first to fourth screens are sequentially spliced ​​and laid on the screening frame 2 from high to low and the apertures are sequentially distributed from small to large, a collecting box is correspondingly arranged on the screening frame 2 under each screen, a vibration device 10 is arranged on each screen, and an electrostatic roller 11 is arranged on one end of the second to fourth screens close to the previous screen.

[0035] A side wall of the wind separation box body 1 is provided with a plurality of wind devices 8 arranged in sequence from top to bottom, and a plurality of waste baffles 9 are arranged in sequence from top to bottom inside the wind separation box body 1, each waste baffle 9 is arranged obliquely, and the high ends of the plurality of waste baffles 9 are arranged one by one corresponding to the plurality of wind devices 8, and a feed port 12 is provided at the top of the wind separation box body 1, and the wind devices 8 and the waste baffles 9 are respectively located on both sides of the space directly below the feed port 12, and the first waste box 7 is located in the wind separation box body 1 and below the low end of the waste baffle 9 at the bottom, and the bottom end of the wind separation box body 1 is open and fixed on the screening frame 2, and the internal space of the wind separation box body 1 is connected with the collecting box below it through the first screen 3.

[0036] The corresponding collecting box below the first sieve 3 is the second waste box 13, which is used to collect the debris screened out by the first sieve 3; the corresponding collecting box below the second sieve 4 is the small-particle seed collecting box 14, which is used to collect small-particle seeds; the corresponding collecting box below the third sieve 5 is the medium-particle seed collecting box 15, which is used to collect medium-particle seeds; the corresponding collecting box below the fourth sieve 6 is the large-particle seed collecting box 16, which is used to collect large-particle seeds.

[0037] Each collection box can be constructed of, for example, an experimental-grade high-molecular-weight polypropylene sheet material without a top, and can be bonded using polyurethane glue.

[0038] The wind separation box body 1 provides space for wind separation.

[0039] Wind coarse screening is achieved through multiple wind devices 8, and the waste selected by wind is discharged into the first waste box through multiple waste baffles 9. The wind devices 8 provide wind to separate most of the seeds from the scale membrane and / or soft hair, and blow the waste to the first waste box 7; the wind devices 8 and the waste baffles 9 are respectively located on both sides of the space directly below the feed inlet 12, which will not affect the falling of the seeds, and also facilitate the waste blown away by the wind device 8 to fall into the first waste box 7 along the waste baffles 9.

[0040] The seeds after being coarsely screened by wind fall into the first screen 3 for subsequent screening.

[0041] The wind separation box body 1 can be constructed of, for example, experimental-grade finely ground aluminum alloy plates, and the plates are connected by welding.

[0042] The wind device 8 is an electric fan, for example, a laboratory-grade metal breeze electric fan module, connected by a USB interface, with four blades, preferably an overall diameter of 12 cm, multiple wind speeds adjustable, a speed of 500-3000 rpm, and a safety net to prevent fingers from accidentally touching the blades. It is fixed to the side of the wind separation box body 1 with bolts.

[0043] The first waste box 7 is used to collect the waste after the wind-driven impurity removal, and can be, for example, a topless rectangular collection box assembled from experimental-grade high-molecular polypropylene sheets, which is connected to the wind-driven separation box body 1 by mortise and tenon joints.

[0044] By setting the first to fourth screens 3 to 6 and the corresponding vibration device 10 on each screen, the impurities and seeds of different particle sizes can be screened. The vibration device 10 vibrates the corresponding screen, which, on the one hand, makes the light scales, membranes, soft hairs and heavier seeds stratified in the upper layer, which is beneficial to the subsequent electrostatic impurity removal, and on the other hand, makes the seeds move to the next level of the screen at the lower end.

[0045] The vibration device 10 can be, for example, a vibration motor. A hole for the vibration motor is reserved at the corner position of the lower end of each screen, and the vibration motor is fixed to the screen by bolts. The vibration motor is required to use an industrial-grade single-fan micro brushless DC vibration motor, a USB interface, a speed of 3000-6000 rpm, a total length of 5.2 cm, a working life of 30,000 hours, and is fixed with bolts.

[0046] The electrostatic roller 11 is an electrostatic rubber roller, which is used for electrostatic impurity removal, and removes impurities that are not completely removed during the wind impurity removal process to ensure that the quality of the net selection is highly pure. Whether it is tiny impurities or seeds of different particle sizes, they can be accurately separated under the fine processing of this device. An insulating roller bracket is provided to support the electrostatic roller 11 and is connected and fixed to the screening frame 2. A fixed shaft is provided inside the electrostatic roller 11 and a plate-shaped electrode is installed for generating static electricity. Its specific structure is a prior art and will not be repeated here.

[0047] By setting up the screening frame 2, a place for vibration screening, a place for electrostatic impurity removal and a place for placing various collection boxes are provided.

[0048] The utility model realizes efficient cleaning and accurate screening of flat-stemmed sedge seeds through a unique method of combining wind cleaning, electrostatic cleaning and vibration screening. The removal rate of scale membrane and soft hair is as high as 98%, the seed cleaning rate is 100%, and the accuracy rate of separating seeds of different particle sizes is also 100%. Compared with the traditional cleaning method, the efficiency is greatly improved.

[0049] The use of a device for cleaning and sorting flat-stemmed Scirpus seeds according to the utility model greatly improves the quality of cleaning and sorting, and also facilitates the development of subsequent scientific research. At the same time, the utility model is easy and quick to operate, and can significantly reduce labor costs. Compared with traditional manual cleaning and sorting, the labor cost is reduced by up to 80%. Taking the processing of a certain amount of seeds as an example, the traditional method is time-consuming and labor-intensive, while the use of this device only requires a small amount of time and manpower. The device cost is low, which reduces the equipment procurement cost and provides strong support for related protection and research work. It provides a reliable solution for the efficient cleaning of flat-stemmed Scirpus seeds, and also provides strong support for the protection and research of flat-stemmed Scirpus.

[0050] The utility model is highly flexible, adjustable and widely applicable in use. The speed and electrostatic intensity of the wind device 8 and the vibration device 10 can be accurately adjusted according to the seed characteristics and separation requirements to meet the cleaning needs of different types of seeds. Whether it is flat-stemmed sedge seeds or other similar seeds, the optimal separation effect can be achieved. When there are many impurities on the surface of the seeds, the wind force and electrostatic intensity can be increased to completely remove the impurities; when the seed particle size is small, the speed of the vibration device 10 is adjusted to make the seeds move more smoothly to avoid damage. The wide applicability enables this device to play a powerful cleaning function in various work scenarios, whether it is a laboratory, a seed processing plant or a field collection site, it can provide reliable protection for the cleaning of flat-stemmed sedge seeds.

[0051] A transformer box 17 and a controller box 18 are fixedly installed below the screening frame 2. With such a design, the transformer box 17 is used to protect the internal transformer, isolate the external environment, and increase the service life of the machine. The transformer uses a multi-output transformer to meet the working voltage requirements of the wind device 8, the vibration motor, and the electrostatic roller 11. The box body is made of experimental-grade polymer polypropylene sheet material, and the top surface is required to be able to open and close, and a circular hole is opened at the bottom for circuit connection. The controller box 18 is used to integrate the functions of the control device. The box body is made of experimental-grade polymer polypropylene sheet material, and the wind device 8 speed control button, the vibration motor speed control button, the electrostatic intensity adjustment button, and the main power button are set on the top surface. The transformer box 17 and the controller box 18 are preferably fixedly installed below the screening frame 2 through a fixing plate 19. The fixing plate 19 uses an experimental-grade finely ground aluminum alloy plate, and the mounting bolt holes of the transformer box 17 and the controller box 18 are reserved. Welded below the screening frame 2, it is convenient to control and adjust the functions of each part.

[0052] The feed inlet 12 is a tapered structure that is wide at the top and narrow at the bottom. With such a design, it is more convenient to pour the seeds to be screened into the wind separation box body 1. The feed inlet 12 can be, for example, four trapezoidal experimental grade high molecular weight polypropylene plates bonded along the bevel edges using polyurethane glue to form a feed inlet 12 that is wide at the top and narrow at the bottom and is through from top to bottom.

[0053] A protective cover 20 is circumferentially arranged on the upper part of the screening frame 2, and the top of the protective cover 20 is arranged higher than each screen. Such a design is used to isolate and protect each screen and the seeds thereon.

[0054] The protective cover 20 is made of transparent material. With such a design, the transparent protective cover 20 can not only effectively isolate and protect the screening frame 2 to prevent external factors from interfering with the cleaning process, but also facilitate the operator to observe the screening situation at any time and adjust the device operating parameters in time. It is preferred to use a high-gloss PMMA polymer organic glass plate, which has a light transmittance of up to 92%, and has the characteristics of easy cleaning and wear resistance, which is convenient for the operator to observe the internal operation of the device and ensure that the device maintains a good appearance and performance during long-term use.

[0055] The periphery of each screen is arranged in close contact with the inner wall of the protective cover 20. Such a design prevents impurities such as seeds or soft hair from falling into the collection box below from the gap between the screen and the protective cover 20 during the vibration screening process, thereby further ensuring the seed selection rate.

[0056] The apertures of the first sieve 3 to the fourth sieve 6 are 0.1 cm, 0.2 cm, 0.3 cm, and 0.5 cm, respectively. This design is used to screen out impurities, small-size seeds, medium-size seeds, and large-size seeds.

[0057] Each collecting box is a drawer-type structure. In this way, the collecting box with a drawer-type structure can be installed on the screening frame 2 in a pull-out manner to facilitate the cleaning of each collecting box.

[0058] A plurality of supporting legs 21 are fixedly provided at the bottom of the screening frame 2. In such a design, the plurality of supporting legs 21 may be, for example, six, two in each group, and the three groups of supporting legs 21 have different heights, which become shorter in the screening sequence direction, so that the screening frame 2 and the screens thereon are arranged in order from high to low.

[0059] The number of the wind devices 8 and the number of the waste baffles 9 are both three.

[0060] The utility model provides an assembly method of a device for cleaning and selecting flat-stalked sedge seeds:

[0061] 1. Bonding the feed inlet: Use polyurethane glue to bond four trapezoidal experimental grade high molecular weight polypropylene sheets along the bevel to form a feed inlet that is wide at the top and narrow at the bottom and runs through from top to bottom, and place them for standby use;

[0072] In the device of the utility model, different parts are made of corresponding high-performance materials. The experimental-grade polymer polypropylene sheet has extremely high durability and excellent sealing. The experimental-grade fine-ground aluminum alloy sheet, with its light weight, is one-third of the weight of traditional steel of the same volume, and has 70% of the strength of steel. It is easy to carry and install the device and can operate stably in various complex environments. The high-gloss PMMA polymer organic glass plate has a light transmittance of up to 92%, and is easy to clean and wear-resistant. It is convenient for operators to observe the internal operation of the device and ensure that the device maintains a good appearance and performance during long-term use. These high-performance materials provide a guarantee for the effective and efficient operation of the device.

[0073] Practical application methods

[0074] After completing the assembly of each part of the device, first turn on the main power supply, then start the wind device, vibration device, and electrostatic drum in sequence. To ensure the best cleaning effect, a small amount of roughly processed threshed seeds can be put in for testing and observation. During this process, pay close attention to the separation situation, and accurately adjust the operating speed of the wind device, vibration device, and electrostatic drum according to the actual separation state to achieve the most ideal cleaning effect.

[0075] After the debugging phase is completed, the roughly processed threshed seeds to be cleaned are slowly poured into the feed port at a uniform speed. During the cleaning process, the waste box needs to be cleaned in time to prevent waste accumulation from affecting the cleaning effect; at the same time, the cleaned seeds should be collected in time to ensure the proper storage of the seeds. Such operation can give full play to the efficient cleaning performance of the device and provide reliable guarantee for the cleaning of flat-stalked sedge seeds.
