Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of agricultural machinery, and in particular to an agricultural dandelion collecting device. Background Art
[0002] Dandelion is a plant with both medicinal and edible properties. Its dried whole herb is used as medicine. It has a bitter and sweet taste and a cold nature, and has the effects of clearing heat and detoxifying, reducing swelling and dispersing stagnation, and promoting diuresis and relieving stranguria. Dandelion is highly nutritious, rich in vitamins, minerals, polysaccharides, and other active ingredients. It also contains a variety of nutrients, including crude fat, vitamins, and protein, and 17 amino acids, seven of which are essential for the human body. Dandelion leaves contain higher levels of potassium, calcium, zinc, and manganese than the average Chinese cabbage. Other organs also contain high levels of potassium, zinc, iron, and manganese. With the exception of the roots, the potassium-to-sodium ratio in all organs is over 10 times higher, contributing to the body's acid-base balance. Dandelion leaves and flowers are edible, raw or cooked. Unopened flower buds can be used to make fried fritters. The whole herb can be dried and brewed into tea, and both the leaves and roots can also be used to make tea. Furthermore, the roots can be dried and roasted to make a coffee substitute. Dandelion, a traditional Chinese herbal medicine, is widely used in livestock production as an ideal feed additive due to its non-residual effects and ability to promote the functioning of the gastrointestinal microbiome. Adding dandelion to feed not only improves egg production and egg quality in laying hens, but also enhances the performance of broiler chickens. Therefore, dandelion has excellent medicinal, nutritional, edible, and livestock benefits, making it widely cultivated by farmers.
[0003] Since dandelion seeds are light, when dandelion flowers and seeds mature, they are easy to scatter and drift away with the wind, making them difficult to collect. If dandelions are picked manually, many dandelion seeds are easily shaken off, so manual collection results in a large loss. Currently, dandelion collection is commonly carried out using the negative pressure adsorption principle, which includes a collector connected to a collection box via a hose. The collection box is provided with a negative pressure blower for generating a negative pressure effect in the collection box. During operation, the collector is manually held and moved around the dandelion planting area, and the dandelions are collected into the collection box under the negative pressure generated by the negative pressure blower. However, since the dandelion fruit has white pappus about 6 mm long, this makes the dandelions fluffy in the collection box, taking up a large amount of space in the collection box, requiring multiple shutdowns for unloading, which seriously reduces the collection efficiency of the dandelions. In some dandelion collection devices, a compression device is provided in the collection box to compress the pappus, which will cause the seed shell to break, affecting the germination rate of the seeds. Therefore, there is an urgent need to design an agricultural dandelion collection device that can improve the collection efficiency of dandelions and protect the seed shell from breaking.

[0031] The negative pressure adsorption component includes a negative pressure fan 33, an air inlet pipe 2, a connecting pipe 3, an air outlet pipe 4 and a collector 7. The separation box 5 is connected to the collector 7 located at the front end of the vehicle 1 through the air inlet pipe 2. The air inlet pipe 2 is connected to the bottom of the screen 6.

[0032] During specific use, the carrier 1 moves in the dandelion planting area, and the negative pressure fan 33 works at the collector 7 to generate negative pressure. The dandelions enter the separation box 5 through the collector 7 under the action of negative pressure. The dandelions entering the separation box 5 move from top to bottom due to the negative pressure and collide with the screen 6, so that the seeds and the pappus are separated.

[0046] Specifically, the provision of the exhaust holes 24 is conducive to the discharge of air, and the provision of the filter cloth 25 is conducive to preventing the hair from being discharged from the exhaust holes 24. The contracted compression box 8 is conducive to improving the compaction of the hair and improving space utilization.
[0047] In order to facilitate the discharge of the pappus, preferably, the rear end of the compression box 8 is detachably connected to an end cover 26, and the end cover 26 is opened to discharge the pappus.
