Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, and in particular relates to an agricultural mechanized fertilization device. Background Technology

[0002] Fertilization refers to agricultural techniques that apply fertilizers to the soil to provide the nutrients needed by plants and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich soil fertility, and improve economic benefits. It is not only beneficial to the growth and development of crop roots, but also helps to improve the soil's water and fertilizer retention capacity.

[0003] Existing agricultural mechanized fertilization devices, while capable of mixing fertilizer raw materials, suffer from a wide variety of raw materials of varying quality, making it difficult to guarantee that the raw materials are free of impurities. If these impurities enter the device, they will not only damage the internal components but also affect the normal operation of subsequent fertilization work. Furthermore, the width of different fertilization areas varies, and failure to control the discharge volume at the discharge port in a timely manner will result in waste. In view of this, we propose an agricultural mechanized fertilization device. Utility Model Content

[0017] The beneficial effects of this utility model are:

[0018] 1. This agricultural mechanized fertilization device, before mixing the fertilizer, first starts the first motor to drive the third rotating shaft. When the third rotating shaft rotates, the two second bevel gears will rotate accordingly. Since the two second bevel gears are facing the same direction, when the two second bevel gears rotate in the same direction, they will drive the two first bevel gears and the two fourth rotating shafts to rotate in the same direction. When the two fourth rotating shafts rotate in the same direction, the two third bevel gears will also rotate in the same direction. When the two third bevel gears rotate in the same direction, they will drive the two fourth bevel gears and the two second rotating shafts to rotate in the same direction. When the two second rotating shafts rotate in the same direction, they will drive the cams to rotate in the same direction. When the two cams rotate in the same direction, under the cooperation of the two connecting rods and the two connecting seats, they will drive the two first fixed plates to slide up and down simultaneously. When the two first fixed plates slide up and down, the screen plate located between the two first fixed plates will also slide up and down. At this time, the raw materials to be used are poured into the top surface of the screen plate through the feed port, and the raw materials can be screened through the screen plate. Excessively large impurities will be left on the top surface of the screen plate, thereby preventing impurities from entering the mixing box and causing damage to the inside of the mixing box, which has practical benefits.

[0019] 2. This agricultural mechanized fertilization device, after the screened raw materials fall into the mixing box, the output shaft of the first motor rotates, which, in conjunction with two pulleys and a belt, drives one of the first rotating shafts to rotate. The rotation of this first rotating shaft, in conjunction with two gears, drives the other first rotating shaft to rotate. As the two first rotating shafts rotate, multiple mixing rollers also rotate, thus mixing the raw materials. This has the advantage of convenience. Starting the valve allows the mixed raw materials to be transported to the water inlet box through the guide pipe. Based on the width of the fertilization area, the second motor starts, driving the threaded rod to rotate. Since the threaded rod has two sections with opposite threads, when the threaded rod rotates, it drives two threaded sleeves and two sliding blocks to slide in opposite directions. When the two sliding blocks slide in opposite directions, the distance between them is adjusted, thus adjusting the position of the two sliding blocks according to the width of the fertilization area. After adjustment, the fertilizer is discharged through multiple discharge holes, avoiding discharge into unnecessary areas, offering convenient and practical advantages. Attached Figure Description
