Description

Technical Field

[0001] The present invention belongs to the field of agricultural power machinery, relates to a seed cleaning and drying device, and is applicable to the cleaning and drying treatment of seeds. Background Art

[0002] The cleaning and drying of seeds are important links to improve the germination rate and planting success rate of seeds. Many seeds are attached with grease, wax layer, impurities or other substances on their surfaces. These substances will hinder the penetration of moisture, affect the development of germ, and even cause seed rot or reduce the germination rate. For example, the grease and wax layer on the surface of Chinese prickly ash seeds will significantly reduce the water permeability and affect the germination of seeds; while the impurities and viscous substances on the surfaces of rapeseed, soybean and other seeds will also have an adverse effect on the germination rate.

[0003] Traditional seed cleaning methods usually rely on manual operation or simple soaking treatment, with low efficiency and incomplete cleaning effect.

[0004] In the process of implementing the present invention, the inventors found that although some existing cleaning equipment can improve the cleaning efficiency, there are often the following deficiencies:

[0005] Separation of cleaning and drying: Most equipment can only complete one of the cleaning or drying processes, and cannot achieve integrated treatment, resulting in cumbersome operation, time-consuming and laborious.

[0006] Poor cleaning effect: Some equipment cannot completely remove the grease, wax layer or impurities on the seed surface, affecting the germination rate of seeds.

[0007] Risk of damage to seeds: Some mechanical cleaning equipment may cause physical damage to the seed surface and reduce the vitality of seeds.

[0008] Limited scope of application: Existing equipment is usually designed for specific seeds and is difficult to meet the cleaning requirements of various seeds. Summary of the Invention

The device adopts a three-way valve design, which can add cleaning liquid, fresh water, and warm air in sequence to ensure the automation and high efficiency of the cleaning and drying process. The design of the small holes on the cross pipe enables the seeds to fully contact the cleaning agent, fresh water, and warm air, ensuring the cleaning effect and drying effect. The design of the pushing plates and pushing rods can drive the lower seeds to rotate, ensuring the uniformity of cleaning and drying.

Subsequently, the waste liquid is discharged through a drain pipe, and a sieve plate is used to intercept the seeds to prevent seed loss. In the stage of rinsing with clean water, by injecting clean water multiple times and controlling the liquid level height, residual impurities are thoroughly removed, and at the same time, floating shriveled seeds are discarded to improve the seed purity. In the drying stage, warm air below 35°C is introduced and the shaft tube is kept rotating to ensure uniform drying of the seeds and avoid over-drying from affecting the seed viability. Finally, the dried seeds are output through a discharge valve to complete the entire treatment process.

[0089] The following is described with reference to the accompanying drawings and a specific embodiment.

[0090] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention.

[0091] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0092] Example 1

[0093] See Figures 1 to 6 . The seed cleaning and drying device described in this embodiment mainly consists of a barrel-shaped container 100, a cover 110, a funnel 111, a drainage system, a supply pipeline system 200, a rotary stirring system, and a discharging system.

[0094] See Figures 1 to 5 , the barrel-shaped container 100 is used to hold the seeds to be cleaned. Its designed capacity is 50 - 100 kg, ensuring that it can meet the requirements of large-scale seed processing. The barrel-shaped container 100 is made of high-strength and corrosion-resistant materials to adapt to the cleaning requirements of different seeds, especially Chinese prickly ash seeds.

[0095] The top of the barrel-shaped container 100 is provided with a sealingly mated cover 110 to ensure that liquid does not leak during the cleaning process. The top cover 110 of the barrel-shaped container 100 adopts a sealed design. The cover 110 is closely fitted with the barrel-shaped container 100 through a sealing ring or gasket to ensure that liquid does not leak during the cleaning process. A funnel 111 is installed on the cover 110 for adding seeds and collecting floating shriveled seeds. The design of the funnel 111 ensures that seeds can smoothly enter the barrel-shaped container 100 and is convenient for collecting and discarding floating shriveled seeds.

[0096] See Figure 7, in a preferred embodiment, an annular overflow groove 112 is designed at the top of the funnel 111, and an overflow pipe 113 is connected to the bottom of the annular overflow groove 112 to achieve automatic collection and discharge of floating shriveled seeds. During the seed cleaning process, when the liquid level in the barrel rises due to stirring and the buoyancy of the seeds, the floating shriveled seeds will flow into the annular overflow groove 112 along with the liquid. The overflow pipe 113 guides the water and floating seeds in the overflow groove to an external collection device, thus realizing automatic separation and collection. This improvement significantly improves the efficiency and quality of seed cleaning, while reducing the operation complexity and labor intensity.

[0097] See Figure 4 and Figure 5 , the device is provided with a drainage system, including a drain pipe 120 and a sieve plate 121 provided at the bottom of the barrel-shaped container 100. A drain valve (not shown in the figure) is installed on the drain pipe 120. The aperture of the sieve plate 121 is smaller than the seed particle size to ensure that the seeds will not be lost when the waste liquid is discharged. The drain pipe 120 is connected to a suitable drainage facility to ensure that the waste liquid can be smoothly discharged and properly treated.

[0098] See Figure 6 , the device is provided with a supply pipeline system 200, and the supply pipeline system 200 includes a first valve 211, a second valve 212 and a third valve 213, which are respectively connected to a cleaning liquid supply unit (not shown in the figure), a clear water supply unit (not shown in the figure) and a air supply unit (not shown in the figure). These valves are connected to the shaft pipe 220 through pipelines, and the shaft pipe 220 is then communicated with the cross pipe 230. A plurality of small holes 231 are provided on the cross pipe 230, and the aperture of the small holes 231 is smaller than the seed particle size to ensure that the liquid and air can be ejected evenly, while preventing the seeds from entering the supply pipeline system 200. Further, multiple rows of small holes 231 are provided on the cross pipe 230, and a plurality of small holes 231 are uniformly arranged in each row, covering the entire length of the cross pipe 230. The distribution design of the small holes 231 ensures that the liquid or air can be ejected evenly from multiple directions, improving the efficiency and uniformity of cleaning and drying. Figure 6 The front and back directions are shown. In some embodiments, small holes 231 can also be provided in the up and down directions. The multi-directional spraying function of the small holes 231 enables the seeds to fully contact the cleaning liquid during the cleaning process, ensuring that the oil and impurities are completely removed; during the drying process, the warm air can be evenly blown onto the seeds, accelerating the evaporation of moisture and ensuring uniform drying of the seeds. The uniform distribution and multi-directional spraying design of the small holes 231 not only improve the treatment effect, but also enhance the stability and reliability of the device, avoiding poor treatment effect or equipment failure caused by uneven spraying.

[0099] The cleaning liquid supply unit is responsible for providing the cleaning liquid for seed cleaning, such as alkaline cleaning liquid. Its main function is to store and transport the cleaning liquid to ensure that the cleaning liquid can be injected into the barrel-shaped container 100 according to the preset concentration and amount.

[0100] In a preferred embodiment, the cleaning liquid supply unit includes the following components:

[0101] Liquid storage tank: Used to store the cleaning liquid, usually made of corrosion-resistant materials to adapt to different types of cleaning agents.

[0102] Metering pump: Used to precisely control the injection volume of the cleaning liquid to ensure the ratio of seeds to the cleaning agent, such as 50:1. The flow rate of the metering pump can be adjusted as needed.

[0103] Pipes and valves: Connect the liquid storage tank to the supply pipe system 200 of the device to ensure the smooth delivery of the cleaning liquid. A first valve 211 is installed on the pipe to control the injection of the cleaning liquid.

[0104] The clean water supply unit is responsible for providing clean water for rinsing the seeds. Its main function is to store and transport clean water to ensure that the clean water can be injected into the barrel-shaped container 100 according to the preset amount.

[0105] In a preferred embodiment, the clean water supply unit includes the following components:

[0106] Clean water storage tank: Used to store clean water, usually made of food-grade materials to ensure water quality safety.

[0107] Water pump: Used to transport clean water from the storage tank to the device, and the flow rate of the water pump can be adjusted as needed.

[0108] Pipes and valves: Connect the storage tank to the supply pipe system 200 of the device to ensure the smooth delivery of clean water. A second valve 212 is installed on the pipe to control the injection of clean water.

[0109] The air supply unit is responsible for providing warm air for drying the seeds. Its main function is to generate and transport warm air to ensure that the warm air can be introduced into the barrel-shaped container 100 according to the preset temperature and amount.

[0110] In a preferred embodiment, the air supply unit includes the following components:

[0111] Air compressor or blower: Used to generate air flow and provide sufficient air volume to meet the drying requirements.

[0112] Air filter: Used to filter impurities and dust in the air to ensure the purity of the air introduced into the seeds.

[0113] Heater: Used to adjust the air temperature to ensure that the warm air temperature is controlled below 35°C to avoid damage to the seeds caused by high temperature.

[0114] Temperature controller: Used to precisely control the warm air temperature to ensure that the temperature is stable within the preset range.

[0115] Pipes and valves: The supply pipeline system 200 connecting the air supply unit and the device ensures the smooth delivery of warm air. A third valve 213 is installed on the pipeline to control the passage of warm air.

[0116] See Figure 5 and Figure 6 , the device further includes a rotary stirring system, which is a key component to ensure the seed cleaning and drying effects. Both ends of the shaft tube 220 are installed on the barrel-shaped container 100 through bearings and connected to the power assembly 300 to ensure that the shaft tube 220 can rotate freely. A bearing seat 141 is provided on the bottom plate 140 of the barrel-shaped container 100, and a bearing is assembled in the bearing seat 141. The bearing uses an oil seal to ensure the rotational sealing performance and prevent cleaning agents, etc. from flowing out from the rotating surface. The horizontal tubes 230 are arranged in multiple layers, with multiple horizontal tubes 230 arranged in each layer and distributed in a spoke-like pattern to ensure the uniform distribution of liquid and air. Figure 6 It shows that 5 layers of horizontal tubes 230 are evenly arranged from top to bottom, with 8 horizontal tubes in each layer and 20 small holes 231 in each horizontal tube. The stirring assembly includes wing plates 240 provided at the outer ends of the horizontal tubes 230, inclined pushing plates 250 and a pushing rod 360 below the bottom horizontal tube 230, which are used to stir the seeds and achieve mixing in the axial and circumferential directions. The power assembly 300 preferably uses an electric motor as the power source, and the electric motor is connected to the shaft tube 220 through a coupling to ensure the smooth transmission of power to the rotary stirring system. The power and speed of the electric motor are selected according to the processing capacity of the device and the characteristics of the seeds to ensure a moderate stirring speed, which can fully mix the seeds without damaging them.

[0117] To achieve precise speed control, the power assembly 300 can be equipped with a speed-changing device or a frequency converter to dynamically adjust the speed according to different cleaning and drying stages. For example, in the cleaning stage, a lower speed helps the seeds to come into full contact with the cleaning liquid; while in the drying stage, appropriately increasing the speed can accelerate the turning of the seeds and improve the drying efficiency.

[0118] The installation of the power assembly 300 needs to ensure its coaxiality with the shaft tube 220 to reduce vibration and wear. In this embodiment, the power assembly 300 is installed on the stable cover 110. Preferably, the power assembly 300 is also equipped with a protective cover to prevent accidental contact by operators and ensure the safe operation of the equipment.

[0119] See Figure 3 and Figure 5 , the discharging system includes a discharging valve 130 provided at the bottom of the barrel-shaped container 100 for discharging the cleaned and dried seeds. The design of the discharging valve 130 ensures the smooth discharge of the seeds and avoids damaging the seeds during the discharging process. During the cleaning process, the discharging valve 130 remains closed to prevent liquid leakage.

[0120] In a further embodiment, the barrel-shaped container 100 is installed by a stable support 400 to ensure the stability and safety of the entire device. The support 400 adopts a metal frame structure, is made of high-strength steel, and has sufficient load-bearing capacity and durability. The barrel-shaped container 100 is fixed to the support 400 by bolts or other fasteners to ensure that it will not displace or shake during the operation of the device. The design of the support 400 also takes into account the center-of-gravity distribution of the barrel-shaped container 100 to ensure that the device remains balanced during the cleaning and drying processes. Preferably, shock-absorbing devices or anti-slip pads are provided at the bottom of the support 400 to reduce vibration and noise during device operation and prevent the device from sliding on the ground. For ease of maintenance and cleaning, the height and angle of the support 400 can be adjusted as needed to ensure that operators can easily access the barrel-shaped container 100 and its related components.

[0121] Example 2

[0122] Based on Example 1, this embodiment adds an automated control system to achieve the intelligence and automation of the seed cleaning and drying processes. The automated control system includes a sensor group, a controller, and an actuator, and can dynamically adjust the cleaning and drying parameters according to preset programs and real-time monitoring data to ensure the efficiency, stability, and consistency of the processing process.

[0123] The sensor group includes a variety of sensors for real-time monitoring of the internal state of the device.

[0124] In a preferred embodiment during substantive examination, a liquid level sensor is used to monitor the liquid level height in the barrel-shaped container 100 to ensure that the clear water level can rise to the funnel 111 area for separating floating shriveled seeds.

[0125] In a preferred embodiment during substantive examination, a temperature sensor is used to monitor the warm air temperature and the seed surface temperature to ensure that the drying process is carried out within a suitable temperature range.

[0126] In a preferred embodiment during substantive examination, a rotational speed sensor is used to monitor the rotational speed of the shaft tube 220 to ensure a moderate stirring speed.

[0127] In a preferred embodiment during substantive examination, a pH sensor is used to monitor the pH value of the cleaning solution to ensure the cleaning effect during the alkaline cleaning stage.

[0128] In a preferred embodiment during substantive examination, a sound sensor is used to monitor the decibel value of the friction sound between seeds to assist in determining the drying end point.

[0129] The controller uses a PLC (programmable logic controller) or a microprocessor and is signal-connected to the sensor group. The controller has a preset program and dynamically adjusts the injection volume of the cleaning liquid, the number of times of rinsing with clean water, the warm air temperature, and the drying time according to the sensor data. The controller also integrates multi-stage control logic, including an alkaline cleaning stage, a floating seed separation stage, and a drying end-point determination stage.

[0130] The actuators include a first valve 211, a second valve 212, a third valve 213, a power assembly 300, a drain valve installed on the drain pipe 120, and a drive module for the discharge valve 130, such as an electromagnetic driver. These actuators are driven by the controller and perform corresponding actions according to the controller's instructions, such as opening and closing of the valves, starting and stopping of the power assembly 300, etc.

[0131] In the alkaline cleaning stage, the pH sensor monitors the pH value of the cleaning liquid in real time. The controller dynamically adjusts the injection volume / discharge volume of the cleaning liquid according to the sensor feedback to ensure that the pH value of the cleaning liquid reaches the preset value. This helps to improve the cleaning effect and remove the grease and impurities on the seed surface.

[0132] In the clean water rinsing stage, the liquid level sensor monitors the height of the clean water surface. The controller controls the injection volume of the clean water according to the liquid level sensor data to ensure that the liquid level rises to the funnel 111 area for separating and discarding the floating shriveled seeds. This helps to improve the purity of the seeds.

[0133] In the drying stage, a temperature sensor or / and a sound sensor are used to monitor the drying state of the seeds. When the temperature sensor detects that the surface temperature of the seeds (for example, 34 °C) reaches the preset value and lasts for a certain period of time (for example, 10 minutes), or when the sound sensor detects that the friction sound between the seeds reaches the preset decibel value (the decibel values of the friction sounds of different seeds are different) and lasts for a certain period of time, the controller determines that the drying process is completed and triggers the opening of the discharge valve 130 to discharge the dried seeds. By means of the collaborative judgment of multiple sensors, the accuracy of the drying end point can be ensured, and damage to the seeds caused by over-drying can be avoided.

[0134] The cleaning and drying parameters for different seeds need to be determined through conventional experiments. In a further embodiment, characteristic data of different seeds, including parameters such as cleaning solution concentration, pH value, drying temperature, and time, are obtained through cleaning experiments and germination rate experiments. The experimental data is stored in a database, such as a relational database (e.g., MySQL) or a time series database (e.g., InfluxDB), for real-time storage and query. The database is integrated with an automated control system, which uses sensors to monitor the seed status (such as temperature, pH value, etc.) in real time and feeds the data back to a controller (such as a PLC). The controller dynamically adjusts the operation of the equipment according to the preset parameters in the database to ensure the accuracy and consistency of the processing process. By dynamically updating the database, the processing requirements of different seeds are adapted, the cleaning and drying processes are optimized, and the germination rate and planting success rate of the seeds are improved.

[0135] By integrating an automated control system, this embodiment significantly improves the efficiency and quality of seed cleaning and drying. The automated control system reduces human intervention, lowers the operation complexity and labor intensity. The multi-stage control logic and real-time monitoring of sensors ensure the stability and consistency of the processing process, significantly enhancing the germination rate and planting success rate of the seeds. In addition, the automated control system can also adapt to the processing requirements of various seeds, and realizes the cleaning and drying of different seeds through preset programs, having a wide range of application prospects.

[0136] Embodiment 3

[0137] This embodiment is a specific implementation of the cleaning and drying method for Chinese prickly ash seeds.

[0138] This embodiment uses the device in Embodiment 1 to clean and dry Chinese prickly ash seeds. The surface of Chinese prickly ash seeds is attached with an oil and wax layer, which causes difficulty in water penetration and affects the development of the germ. Through the efficient cleaning and drying treatment of this device, the cleaning quality of Chinese prickly ash seeds can be significantly improved.

[0139] The cleaning and drying steps are as follows.

[0140] 1. Seed input

[0141] Put 100 kg of Chinese prickly ash seeds to be cleaned into the barrel-shaped container 100 through the funnel 111.

[0142] 2. Cleaning solution injection

[0143] Start the first valve 211 to inject the cleaning solution into the barrel-shaped container 100. The cleaning solution is an alkaline cleaning agent (such as 2.5% NaOH solution), and the ratio of seeds to the cleaning agent is 50:1. The cleaning time is generally 20 - 30 minutes. The alkaline cleaning agent can effectively decompose the oil and wax layer on the seed surface and improve the water permeability.

[0144] 3. Soaking treatment (optional)

[0145] According to the specific situation of the Chinese prickly ash seeds, soaking treatment can be selectively carried out. For example, the Chinese prickly ash seeds are first soaked for 30 minutes to ensure that the cleaning agent can fully act on the seed surface.

[0146] 4. Stirring and cleaning

[0147] Start the power component 300 to drive the rotary stirring system to start working. The wing plates 240, the pushing plates 250 and the pushing rods 360 on the horizontal pipe 230 stir the seeds, so that the seeds are in full contact with the cleaning liquid, removing the grease and impurities on the seed surface. The stirring speed should be moderate, and 20 r / min is recommended to ensure that the seeds can be fully cleaned while avoiding damage to the seeds.

[0148] 5. Waste liquid discharge

[0149] Open the drain valve on the drain pipe 120 to discharge the waste liquid from the barrel-shaped container 100. The sieve plate 121 will intercept the seeds to prevent the seeds from being discharged with the waste liquid. The discharged waste liquid should be properly treated to avoid environmental pollution.

[0150] 6. Rinsing with clean water

[0151] Close the drain pipe 120, start the second valve 212, and inject clean water into the barrel-shaped container 100 for rinsing with clean water. Control the liquid level height of each rinsing to rise to the funnel 111 area to ensure that the seeds can be fully rinsed. The rotary stirring system continues to stir slowly to make the seeds in full contact with the clean water, removing the residual cleaning agent and impurities. The number of rinsing times is generally 2 - 4 times, and the rinsing time for each time is 25 minutes. During the rinsing process, when the clean water level rises to the funnel 111 area, the shriveled seeds will float and gather in the funnel 111 area, and these floating seeds are discarded through the funnel 111 to improve the purity of the seeds.

[0152] 7. Drying treatment

[0153] After discharging the waste liquid from the last rinsing, start the third valve 213 and continuously introduce warm air at 30 - 35 °C into the barrel-shaped container 100. At the same time, keep the shaft pipe 220 rotating to make the seeds dry evenly in the warm air. The drying time is 30 - 60 minutes, and the rotation speed is 20 - 30 r / min. During the drying process, the drying state of the seeds can be monitored through the temperature sensor and the sound sensor. When the temperature sensor detects that the surface temperature of the seeds reaches the preset value and lasts for a certain time, or the sound sensor detects that the friction sound between the seeds reaches the preset decibel value and lasts for a certain time, it indicates that the seeds have been dried.

[0154] 8. Seed discharge

[0155] The dried seeds are discharged from the barrel-shaped container 100 through the discharge valve 130. The discharging process should be carried out smoothly to avoid impacting and damaging the seeds. The discharged seeds should be properly collected and stored for subsequent use.

[0156] After cleaning, the surface of the Chinese prickly ash seeds has no smell of oil oxidation, the texture of the seed shell is clear, there is no obvious oily gloss, the surface texture is clear, and there is no greasy feeling when touched by hand. After the moisture on the seed surface dries, when holding the seeds by hand, there is an obvious friction sound between the seeds.
