Description

Technical Field

[0001] The utility model relates to a liquid fertilizer applicator. Background Art

[0002] Fertilizer products can be divided into solid fertilizers, liquid fertilizers and gas fertilizers according to their state. Because gas fertilizers are very rare, we usually see solid and liquid fertilizers. Traditional fertilizers are usually solid fertilizers, in the form of granules or powders. With the development of the fertilizer industry, liquid fertilizers are becoming more and more common, and people can use them through irrigation and spraying, which is more conducive to rapid absorption by plants. Compared with solid fertilizers, liquid fertilizers are easier to be absorbed by plants, and the absorption and utilization rate is high. Liquid fertilizers are relatively uniform under proper use conditions, and there will be no phenomenon of excessive fertilization of solid fertilizers in a certain location.

[0003] In the authorized Chinese utility model patent "Announcement No.: CN208370224U, Name: Liquid Fertilizer Fertilization Equipment", liquid fertilization is completed through a fertilizer spray device. During the fertilization process, multiple nozzles are used to fertilize multiple crops at the same time, and the fertilization efficiency is high. However, in the above application, the nozzles are used for fertilization, and the position of the nozzles is fixed, so it is difficult to control the depth of fertilization, and thus it is difficult to control the depth of fertilization according to the different crops, resulting in large differences in the fertilization effects of different crops. At the same time, in order to prevent the liquid fertilizer from settling, a stirring structure is generally provided in the prior art, but the stirring structure is generally a mechanical stirring method, and the stirring method is single, and the stirring effect is poor during use, which affects the uniformity of the liquid fertilizer.

At the same time, when the fertilizer spreader moves, gas can be sprayed into the liquid storage tank 2 to stir and mix the liquid fertilizer in the liquid storage tank 2. The auxiliary stirring component 6 mixes the liquid fertilizer to ensure the uniformity of the particles in the liquid fertilizer, thereby avoiding the precipitation of the liquid fertilizer during transportation or fertilization, which affects the fertilization effect or blocks the fertilizer pump 31.

[0068] The fertilization mechanism 3 includes a fertilization pump 31, which is installed on the top of the liquid storage tank 2. The inlet end of the fertilization pump 31 is connected to an inlet pipe 32, and one end of the inlet pipe 32 is connected to the top surface of the liquid storage tank 2.

[0078] When in use, according to different crops and different application positions, the power source 42 is used to drive the threaded column 43 to rotate, thereby driving the height adjustment plate 44 to move along the positioning column 45, thereby driving the transfer box 34 and the fertilizer barrel 35 to move in the same direction.

[0085] After fertilization is completed, the fertilization cylinder 35 moves upward. At this time, the fertilization cylinder 35 passes through the scraping component 5. During the movement of the fertilization cylinder 35, the scraping brush 52 can be used to clean the fertilization cylinder 35, and impurities such as soil can be scraped off from the fertilization cylinder 35 to ensure the cleanliness of the fertilization cylinder 35 and avoid clogging of the fertilization cylinder 35.

[0086] The disassembly plate 53 and the disassembly bolts 54 can be used to facilitate the removal of the scraping brush 52 from the support platform 1, so that the scraping brush 52 can be replaced easily.

[0087] The plurality of disassembly plates 53 are all arranged at an angle, and the length of the disassembly plates 53 decreases from top to bottom.
