Description

Technical Field

[0001] The invention relates to the technical field of grading and cleaning, in particular to a device for grading and cleaning beet seeds. Background Art

[0002] Beet seeds are the basis for growing beets, an important economic crop, and have the following characteristics: 1. Irregular seed shape: The seed coat of beet seeds is woody, thick, hard, and irregular in shape, resulting in relatively weak germination ability.

[0003] 2. The seed husk contains many chemicals: The chemicals contained in the seed husk of beet seeds inhibit seed germination to some extent, resulting in a low germination rate, and direct sowing affects the germination rate.

[0004] 3. Seeds vary in size: Beet seeds vary greatly in size and germination and emergence times are inconsistent.

[0005] 4. Rough surface of seeds: The surface of beet seeds is rough.

[0006] Based on the above characteristics, beet seeds must undergo a series of processing before sowing, including cleaning, polishing, grading and selection, chemical cleaning, priming, pellet coating, etc. to make the seed particle size uniform and greatly improve its germination rate, so that it can be suitable for mechanized precision sowing and field management.

[0007] In addition, the outer coat of beet seeds contains a variety of chemicals that inhibit germination in some cases. Therefore, before the beet seeds are primed and pelleted, the beet seeds need to be chemically cleaned to reduce the concentration of chemicals outside the seed coat, thereby improving the survival rate and germination rate.

[0008] However, existing beet seed grading and cleaning equipment has obvious deficiencies in many aspects. For example, existing beet seed grading and cleaning equipment often has bottlenecks in cleaning efficiency and cannot achieve comprehensive and efficient cleaning of beet seeds. This is mainly due to limitations in equipment design, such as the limited number of cleaning chambers and the single function of the stirring component. In addition, the cleaning liquid in the cleaning chamber often cannot be flexibly adjusted, resulting in limited cleaning effects. This lack of flexibility in design not only limits the improvement of cleaning effects, but may also cause waste of cleaning liquid and environmental pollution.

[0009] In addition, the stirring components of existing beet seed grading and cleaning equipment often only have a single rotational motion mode, which cannot adapt to the cleaning needs at different stages. This single motion mode limits the stirring component from fully stirring the beet seeds, affecting the cleaning effect. Especially in the early and late stages of cleaning, the degree and distribution of dirt on beet seeds are often different, requiring different stirring methods and strengths.

[0010] Therefore, it is necessary to provide a beet seed grading and cleaning device to solve the above problems. Summary of the invention

[0011] In order to solve the above problems, the present invention provides the following technical solutions: a beet seed grading and cleaning device, comprising a separate stirring component and a plurality of cleaning chambers; Wherein, the separate stirring assembly comprises: A substrate, the bottom of which is detachably connected to a loading frame, and the side of the loading frame is provided with a plurality of through holes; A motor, which is fixed on the substrate, and has an output end, and the output end is connected to an output shaft; A stirring assembly, which is powered by the output shaft, and includes at least a center rod and a stirring blade mounted on the center rod, wherein the center rod has a through inner flow channel in the middle so that gas can be injected into the top of the center rod and discharged from the bottom of the center rod; The loading frame is pre-installed with beet seeds to be cleaned, and the separate stirring assembly is circulated in multiple cleaning bins by external equipment.

[0012] Further, as a preference, a transmission cylinder is fixed above the center rod, an air outlet hole communicating with the inner flow channel is opened at the bottom of the transmission cylinder, and an air inlet hole communicating with the interior of the transmission cylinder is also opened on the outer wall of the transmission cylinder; Two symmetrically arranged limiting sliding grooves are provided on the inner wall of the transmission cylinder, and limiting sliding blocks corresponding to the limiting sliding grooves are fixed on both sides of the output shaft.

[0013] Further, as a preference, an outer sliding groove is opened on the outer wall of the transmission cylinder, and the outer sliding groove is elliptical. A support seat is fixed under the base plate, and a telescopic rod is fixed on one side of the support seat. The telescopic rod has a telescopic end, and the telescopic end slides through the support seat and can extend into the outer sliding groove.

[0014] Further, as a preference, a first one-way valve is provided in the air inlet hole, the first one-way valve only allows gas to enter from the outside of the transmission cylinder to the inside of the transmission cylinder, and a second one-way valve is provided in the air outlet hole, the second one-way valve only allows gas to enter from the inside of the transmission cylinder to the inner flow channel.

[0020] Compared with the prior art, the present invention provides a beet seed grading and cleaning device, which has the following beneficial effects: In the present invention, efficient and comprehensive cleaning of beet seeds is achieved by combining multiple cleaning chambers with a separate stirring assembly.

DETAILED DESCRIPTION

[0024] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned description of the drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0025] Example: Please refer to Figure 1-Figure 4 In an embodiment of the present invention, a beet seed grading and cleaning device is provided, comprising a separate stirring component 5 and a plurality of cleaning chambers 1; Different cleaning chambers 1 are pre-installed with different liquids, and the different liquids refer to liquids with different cleanliness levels or different components.

[0026] Wherein, the separate stirring assembly 5 comprises: A substrate 51, the bottom of which is detachably connected to a loading frame 52, and the side of the loading frame 52 is provided with a plurality of through holes; A motor 53 fixed on the substrate 51, wherein the motor 53 has an output end connected to an output shaft 54; A stirring assembly 55, which is powered by the output shaft 54, and includes at least a central rod 551 and a stirring blade 552 mounted on the central rod 551. The central rod 551 has a through inner flow channel 554 in the middle so that gas can be injected into the top of the central rod 551 and discharged from the bottom of the central rod 551; The loading frame 52 is pre-placed with beet seeds to be cleaned, and the separate stirring assembly 5 is circulated in a plurality of cleaning bins 1 by an external device.

[0027] The implementation includes the following steps: Step 1: Place the beet seeds in the loading frame 52 of the separate stirring assembly 5 , and connect (for example, by threading) the loading frame 52 to the bottom of the base plate 51 .

[0028] Step 2: Different liquids (based on the degree of cleanliness or composition) are pre-placed in different cleaning chambers 1. These liquids include water, detergents, disinfectants or other special solutions, which are intended to remove impurities, soil or pathogens on the surface of the seeds.

[0029] Step 3: Place the separate stirring assembly 5 in one of the cleaning bins 1, start the motor 53, and drive the stirring assembly 55 to rotate through the output shaft 54. The central rod 551 and the stirring blade 552 of the stirring assembly 55 start to work, stirring and turning the beet seeds in the loading frame 52.

[0030] Step 4: Inject gas (such as air) into the top of the center rod 551 through the inner flow channel 554 that runs through the middle of the center rod 551. The gas is discharged from the bottom of the center rod 551 to form bubbles or airflow, which helps to further stir the seeds and increase the cleaning effect.

[0031] Step 5: The separate stirring assembly 5 is transferred between multiple cleaning chambers 1 by external equipment (such as a hanging rail or a mechanical arm). The liquid in each cleaning chamber 1 cleans the beet seeds at different stages.

[0032] For example, in the first cleaning chamber 1, a relatively mild liquid is used for preliminary rinsing to remove most of the surface impurities.

[0033] In the subsequent cleaning chamber 1, a cleaner liquid or a liquid with a specific composition is used for deep cleaning to remove more difficult stains.

[0034] After being cleaned in a plurality of cleaning chambers 1, the beet seeds reach the required cleanliness.

[0035] Step 6: The separate stirring assembly 5 is moved to the collection area, and the cleaned beet seeds are taken out from the loading frame 52 for subsequent processing (such as drying, packaging, etc.).

[0036] In this embodiment, the beet seeds can be cleaned efficiently and comprehensively by using a plurality of cleaning chambers 1 and a separate stirring assembly 5. The liquid in different cleaning chambers 1 can be flexibly adjusted as needed, and the waste of water resources and chemical cleaning agents can be reduced by accurately controlling the amount and type of cleaning liquid used.

[0037] In addition, the detachable connection design between the loading frame 52 and the base plate 51 makes the cleaning and maintenance of the equipment more convenient and quick, and facilitates loading and unloading of materials.

[0038] In this embodiment, two symmetrically arranged limiting sliding grooves 58 are provided on the inner wall of the transmission cylinder 57 , and limiting sliding blocks 56 corresponding to the limiting sliding grooves 58 are fixed on both sides of the output shaft 54 ​​.

[0039] An outer groove 59 is formed on the outer wall of the transmission cylinder 57, and the outer groove 59 is elliptical. A support seat 510 is fixed below the base plate 51, and a telescopic rod 511 is fixed on one side of the support seat 510. The telescopic rod 511 has a telescopic end, and the telescopic end slides through the support seat 510 and can extend into the outer groove 59.

[0040] Therefore, during implementation, the motor 53 is started first, and the output shaft 54 ​​starts to rotate, driving the stirring assembly 55 to stir.

[0041] Specifically, since two symmetrically arranged limiting grooves 58 are provided on the inner wall of the transmission cylinder 57 and limiting sliders 56 corresponding to the limiting grooves 58 are fixed on both sides of the output shaft 54, when the output shaft 54 ​​rotates, the transmission cylinder 57 also starts to rotate.

[0042] In addition, when the telescopic end of the telescopic rod 511 extends into the outer slide groove 59, due to the elliptical design of the outer slide groove 59, the telescopic end will guide the transmission cylinder 57 (and the stirring assembly 55 connected thereto) to move up and down while rotating.

[0043] As the stirring assembly 55 rotates and moves up and down, the beet seeds are fully stirred and cleaned in the loading frame 52, and the cleaning liquid contacts the seeds through the through holes on the loading frame 52. At the same time, the bubbles and airflow generated by the stirring also help to improve the cleaning effect.

[0044] It should be noted that the stirring component 55 can switch between two movement modes, that is, the stirring component 55 can only rotate, or move up and down while rotating. This composite movement mode can adapt to the cleaning needs at different stages, comprehensively stir the beet seeds, and improve the cleaning effect.

[0045] In addition, a transmission cylinder 57 is fixed above the center rod 551, and an air outlet 513 communicating with the inner flow channel 554 is formed at the bottom of the transmission cylinder 57, and an air inlet 512 communicating with the interior of the transmission cylinder 57 is formed on the outer wall of the transmission cylinder 57; A first one-way valve is provided in the air inlet 512, and the first one-way valve only allows gas to enter the interior of the transmission cylinder 57 from the outside of the transmission cylinder 57. A second one-way valve is provided in the air outlet 513, and the second one-way valve only allows gas to enter the inner flow channel 554 from the interior of the transmission cylinder 57, thereby ensuring one-way transmission of the gas.

[0046] Furthermore, a piston 515 is fixed to the bottom of the output shaft 54 ​​.

[0047] During implementation, as the transmission cylinder 57 descends, the space formed between the interior thereof and the piston 515 increases, forming a negative pressure, the first one-way valve opens, and external air enters the transmission cylinder 57 through the air inlet 512 .

[0048] When the transmission cylinder 57 gradually rises, the space formed between it and the piston 515 is reduced, the gas is compressed, the second one-way valve opens, and the gas enters the inner flow channel 554 through the outlet hole 513 and is discharged from the bottom of the center rod 551 to the vicinity of the stirring assembly 55.

[0049] That is to say, in this embodiment, the transmission cylinder 57 continuously repeats the above steps during the rising and falling process to form an air pump structure, thereby realizing the function of automatically providing gas to the stirring assembly 55 without the need for additional gas supply equipment or control system, thereby reducing energy consumption and operating costs.

[0050] In this embodiment, an elastic limiting member 514 is fixed on the inner top wall of the transmission cylinder 57 .

[0051] In this embodiment, a plurality of reinforcing rods 553 are connected between the central rod 551 and the stirring blade 552 . A nozzle 555 is installed on the reinforcing rod 553 at the bottom. The nozzle 555 is directed vertically downward. The reinforcing rod 553 at the bottom is also connected to the inner flow channel 554 .

[0052] That is, the nozzle 555 on the bottom reinforcing rod 553 is connected to the inner flow channel 554. When the gas passes through the inner flow channel 554, part of the gas is guided to the nozzle 555. The nozzle 555 sprays the gas in a vertical downward direction to form a gas flow or bubbles.

[0053] It should be noted that, in this embodiment, the side of the loading frame 52 is provided with a plurality of through holes, while the bottom of the loading frame 52 does not have through holes. Then, these airflows or bubbles act on the beet seeds at the bottom of the loading frame 52, causing them to be subject to upward buoyancy.

[0054] As the gas is continuously sprayed, the seeds at the bottom are gradually floated up and further dispersed and cleaned under the stirring action of the stirring blade 552 .

[0055] In this embodiment, the top of the cleaning chamber 1 has an opening, a liquid inlet pipe 2 is placed at the opening, the bottom of the cleaning chamber 1 is closed and connected to a liquid discharge pipe 3, and a temperature controller 4 is also provided at the bottom of the cleaning chamber 1.

[0056] The liquid inlet pipe 2 and the liquid discharge pipe 3 cooperate with each other to realize automatic replacement of the liquid, and the set temperature controller 4 can monitor the temperature of the liquid in the cleaning chamber 1 in real time and adjust the temperature appropriately.

[0057] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
