Description

Technical Field

[0001] The utility model relates to an automatic fertilizer spreader for agricultural planting, belonging to the technical field of agricultural planting. Background Art

[0002] Fertilizers contain various nutrients needed by plants, such as nitrogen, phosphorus, potassium, etc. These nutrients are necessary for the normal growth of crops, provide the nutrient needs of crops, meet the nutritional conditions required for crop development, improve land productivity, and promote the development of agricultural production. The disease and insect resistance of crops are closely related to soil fertility. The supply of nutrients in fertilizers can make the root system of crops stronger, thereby increasing the crop's resistance to diseases and pests and reducing the harm of diseases and pests to crops.

[0003] The existing patent number is CN214102312U, which is an automatic fertilizer spreader for agricultural planting. When uniform fertilization is required, the device pours the fertilizer into the inside of the charging box by hand, and then rotates the output end of the first motor to drive the semicircular block to rotate. The rotation of the semicircular block causes the screen plate to shake up and down, and at the same time, the fertilizer flowing from the charging box to the top of the screen plate is shaken, and the fertilizer is then evenly spread on the ridge blocks from the discharge trough, so that the fertilizer is not generally evenly spread on the ridge blocks when it flows out of the charging box, and at the same time, some crops are prevented from not growing well, thereby improving the practicality of the device. However, this device cannot automatically spread the fertilizer when the device is running and starting and stopping, so it is easy to spread the fertilizer at the moment the fertilizer enters, but when turning a corner or stopping the machine, the fertilizer will continue to be thrown out, which is easy to cause fertilizer accumulation at the start and stop position; and when spreading fertilizer, due to the existence of ridges, the gaps between ridges of different crops are different, and the fertilizer spreading angle of this device is limited, which is difficult to adjust according to the gaps between ridges, so that part of the fertilizer is easily scattered on the side of the ridge, affecting the use effect of the fertilizer.
