Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of astragalus planting devices, in particular to a seed pre-screening device for astragalus planting. Background Art
[0002] Astragalus is a common Chinese medicinal material with extremely high medicinal value. In the process of growing Astragalus, the quality and pretreatment of seeds are crucial for subsequent germination and growth.
[0003] Astragalus seeds have a hard shell. If they are not crushed and broken, the seeds will not germinate smoothly. Effective crushing and breaking the shell can increase the germination rate and survival rate of the seeds, laying the foundation for the good growth of Astragalus.
[0004] However, the traditional astragalus seed pretreatment screening device has obvious defects. In terms of grinding and crushing, the traditional device has poor crushing effect and cannot fully crush the seed shell, resulting in some seeds not being effectively shelled, affecting the germination rate. At the same time, in terms of the soaking germination effect, the traditional device lacks precise constant temperature regulation function, and the temperature control is unstable, which makes the soaking environment of the seeds not ideal, thereby affecting the germination effect and quality of the seeds. These defects seriously restrict the efficiency and quality of astragalus cultivation and need to be improved urgently. Utility Model Content

[0033] The working principle of the utility model is as follows: The seed pre-screening device for Astragalus planting realizes efficient pretreatment of Astragalus seeds through a series of components working in coordination. The Astragalus seeds in the feed bin enter the feeding adjustment mechanism, and the motor drives the rotating shaft to drive the baffle plate to adjust the seeds to enter the crushing channel evenly and in an appropriate amount. In the crushing mechanism on both sides of the channel, the second motor drives the roller to drive the crushing belt to crush the seeds and break the shells. The crushed seeds fall onto the inclined screen, and the oscillation motor drives the screen to vibrate. Qualified seeds fall into the soaking pool from the seed outlet, and the waste residue produced by the crushing falls into the waste residue collection box. The constant temperature adjustment mechanism in the soaking pool monitors the water temperature in real time through the temperature sensor, and the PLC controller controls the operation of the electric heating plate according to the monitoring results to keep the water temperature in the soaking pool constant, creating a suitable germination environment for the seeds.
[0034] Before using the utility model, first connect the external power supply, and its specific working process is as follows:
[0035] 1. Preparation: Pour the astragalus seeds to be pretreated into the feed bin 2, and inject an appropriate amount of water into the soaking tank 7. Start the device and ensure that all components operate normally.
[0036] 2. Feeding adjustment: The motor 11 drives the baffle plate 10 on the rotating shaft 9 to rotate, and controls the feeding speed and amount of seeds at the bottom outlet of the feed bin 2, so that the seeds enter the crushing channel 6 stably and in an appropriate amount.
[0037] 3. Crushing and breaking the shells: The crushing belts 14 on both sides of the crushing channel 6 are driven by the motor 2 15 to rotate in the same direction to crush and break the shells of the seeds entering the channel. The crushing belts 14 rotate in the same direction, so the two crushing belts 14 located inside the crushing channel 6 move in opposite directions, forming a structure similar to crushing and rubbing inside the crushing channel 6, and the two crushing belts 14 move relative to each other up and down to crush and rub the seeds.
[0038] 4. Screening and separation: The crushed seeds fall onto the screen 3, the oscillation motor 4 is started, driving the screen 3 to vibrate, and the seeds slide out of the seed outlet 5 along the screen 3 and enter the soaking tank 7; the waste residue falls through the screen 3 into the waste residue collection box 19.
[0039] 5. Constant temperature soaking: The seeds falling into the soaking pool 7 are soaked under the action of the constant temperature adjustment mechanism. The temperature sensor 17 monitors the water temperature in real time. When the water temperature is lower than the set value, the PLC controller 16 controls the electric heating plate 18 to heat; when the water temperature reaches the set value, the electric heating plate 18 stops heating to keep the water temperature in the soaking pool constant and promote seed germination.
[0040] 6. Waste residue cleaning: After working for a period of time, the waste residue collection box 16 is taken out through the cleaning port 21, the waste residue therein is cleaned, and then the waste residue collection box 19 is put back to its original position to continue collecting waste residue.
[0041] 7. Equipment maintenance: Regularly open the inspection door 20 to inspect, maintain and repair the components inside the device to ensure long-term stable operation of the device.
[0042] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
