Abstract
Description
Technical Field
[0001] The utility model relates to a seeding and fertilizing machine, belonging to the technical field of agricultural seeding and fertilizing. Background Technique
[0002] China is a large agricultural country. When sowing crops, the agricultural machinery needed has relatively single functions. It is necessary to first use a rotary tiller to loosen and level the soil, and then use two sets of machinery or a set of machinery with fertilizing and sowing functions to carry out fertilizing and sowing respectively.
[0003] With the development of agricultural machinery, there are also some seeding machines that can complete the fertilizing work at the same time after sowing, but there are often the following defects:
[0004] First, some agricultural machinery mixes seeds and fertilizers in a certain proportion and broadcasts them into the farmland at the same time when sowing. Since the seeds and fertilizers are close to each other, it is easy to cause the phenomenon of burning seedlings.
[0005] Second, during the sowing or fertilizing process, the soil easily blocks the seed discharging port of the seed metering device for sowing.
[0006] To sum up, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to improve it. Content of the Utility Model
[0007] Aiming at the deficiencies in the background technique, the utility model provides a seeding and fertilizing machine, which can realize seeding and fertilizing at the same time, and the seeding and fertilizing processes can be broadcast separately to avoid burning seedlings; in addition, it can also avoid blocking of the seed discharging port.
[0008] To solve the above technical problems, the utility model adopts the following technical solutions:
[0009] A seeding and fertilizing machine includes a frame. A seed hopper and a fertilizer hopper are provided at the upper end of the frame. A seed metering device is provided at the front side of the lower end of the frame. The seed metering device is communicated with the seed hopper through a lower seed plastic pipe. A lower fertilizer discharging pipe is provided at the rear side of the seed metering device. The lower fertilizer discharging pipe is communicated with the fertilizer hopper. A soil covering device is provided at the rear end of the lower fertilizer discharging pipe.
[0010] Further, seed metering devices, lower fertilizer discharging pipes and soil covering devices are provided on both sides of the frame, so that the equipment can sow two rows at a time.
[0011] Further, a first support arm and a second support arm are respectively provided on both sides of the frame. The upper ends of the first support arm and the second support arm are hinged to the lower end of the frame. A transverse connecting rod is provided between the first support arm and the second support arm. One end of the transverse connecting rod is hinged to the first support arm, and the other end is hinged to the second support arm.
[0012] Further, the seed metering device is installed at the lower end of the first support arm, and the lower fertilizer discharging pipe is installed at the lower end of the second support arm.
[0013] Further, two traveling wheels are provided at the rear end of the frame. A push-pull rod is provided between the traveling wheels and the second support arm. The front end of the push-pull rod is hinged to the lower end of the second support arm, and the rear end of the push-pull rod is eccentrically hinged to the traveling wheel.
[0014] Further, the soil covering device includes a vertical fixed rod. Two soil covering plates are installed at the lower end of the vertical fixed rod. The two soil covering plates are arranged at a certain angle so that their openings face forward.
[0015] Further, a power transmission gearbox is provided on the frame. A driving sprocket is installed on the transmission shaft of the power transmission gearbox. Feeding devices are respectively provided at the bottoms of the seed hopper and the chemical fertilizer hopper.

After the seed metering device opens a furrow, seeds are sown into the soil in the furrow, and the rear lower fertilizer discharging pipe sows chemical fertilizer onto the soil surface. The subsequent soil covering device fills the furrow. By means of this equipment, sowing, fertilizing and filling are simultaneously achieved, so that the seeds and the chemical fertilizer are separated to avoid burning the seeds.
[0019] 2. The frame, the first support arm, the second support arm and the transverse connecting rod form a parallelogram linkage. Driven by the push-pull rod, the first support arm and the second support arm swing back and forth to prevent the seed discharging port of the seed metering device and the fertilizer discharging port of the lower fertilizer discharging pipe from being blocked.
