Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a small seeding and fertilizing machine. Background Technology

[0002] Agricultural row sowing is a highly efficient sowing technique that uses machinery to evenly scatter seeds in shallow furrows, forming neat rows of crops with fixed spacing, facilitating subsequent field management. It improves sowing efficiency, reduces manual labor, and helps achieve uniform crop distribution, thereby optimizing crop growth conditions. A search revealed Chinese invention application CN112425326A, which discloses an integrated agricultural sowing and fertilizing device. The device includes a fertilizing mechanism connected to a support body at the front end of a tilling mechanism, and a sowing mechanism connected to the support body at the rear end. In the tilling mechanism, a plow base is fixedly connected to the support body, a plow handle is connected to the plow base, and a plow shaft is connected in a V-shape to both sides of the lower end of the plow handle. The plow blades are connected to the plow shaft via bearing assemblies. In the fertilizing mechanism, a fertilizing base is connected to the upper end of the support body, a fertilizing box is fixed to the top of the fertilizing base, and a feeding port is located at the bottom of the fertilizing box. A fertilizing feeding seat connects to the feeding port, and an outlet is formed inside the fertilizing feeding seat. A fertilizing distributor is located in the outlet, and the end of a fertilizing shaft is connected to the fertilizing base via bearings, passing through the center of the fertilizing distributor. In the sowing mechanism, a seed box is connected to the upper end of the seeder. This technical solution occupies a small area, solves the problem of separating fertilization and sowing in small-scale agriculture, and completes fertilization and sowing operations in one operation. However, the above method also has the following shortcomings: fertilization and sowing in the same furrow can easily lead to seed burning. Summary of the Invention

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Please see Figure 1-4 This invention provides a technical solution: a small seeding and fertilizing machine, including a frame 1, which is formed by welding rectangular tube profiles and has a traction frame 2 installed at the front end of the frame 1 for connecting with a tractor. Support plates 7 are symmetrically provided on the left and right sides of the front part of the frame 1, and a front pressing roller 8 is installed between the two support plates 7. A tilting and flipping roller frame 12 is hinged to the rear of the frame 1, and a rear pressing wheel 13 is installed at the end of the roller frame 12. Two tilting and flipping round rods 14 are hinged to the rear end of the frame 1. The lower end of the round rods 14 passes through the bracket on the roller frame 12 and is slidably connected to it. A spring 15 is sleeved on the round rod 14, and the spring 15 is used to apply downward pressure to the roller frame 12 for flipping. The rear pressing wheel 13 is used to level the soil covering the seed. The front pressing roller 8 and the rear pressing wheel 13 are dumbbell-shaped, which can shape the ridges.

[0018] A downward-extending soil-breaking plow 3 is installed on the front center of the frame 1. The plow 3 turns the soil to both sides when moving. Two symmetrical discs 4 are installed at the bottom front of the frame 1, arranged in an outward V-shape. A fertilizer applicator 6 is installed on the upper front of the frame 1. The fertilizer applicator 6 includes a hopper a61, with two symmetrical discharge valves a62 installed at the bottom of the hopper a61. The discharge point of the discharge valves a62 is located between the soil-breaking plow 3 and the discs 4. The soil-breaking plow 3 and the discs 4 turn the soil to cover the fertilizer. A downward-extending leveling plate 5 is installed on the lower front of the frame 1. The leveling plate 5 is located between the discs 4 and the front pressing roller 8, with its lower end bent backward. The leveling plate 5 and the front pressing roller 8 are used to level the soil covered with fertilizer. A sowing mechanism 9 is installed in the middle of the frame 1. Two reversible plows 11 are symmetrically installed at the rear of the frame 1. The reversible plows 11 are used to cover the soil after sowing.

[0019] The sowing mechanism 9 includes a hopper b91, a discharge valve b92, and a sowing plow 94. The discharge valve b92 is installed at the lower end of the hopper b91. A seed discharge pipe 93 is installed at the lower outlet of the discharge valve b92 (the discharge valves a62 and b92 are commercially available mature products, which use a rotating impeller to carry the material to the lower outlet). The lower end of the seed discharge pipe 93 is inserted into the middle of the sowing plow 94. The upper plow handle of the sowing plow 94 is fixedly installed with the frame 1. The movement trajectory of the sowing plow 94 is located between two rows of fertilizer furrows, that is, the sowing furrow is located between two rows of fertilizer furrows.

[0020] The lower two sides of the hopper a61 are equipped with support legs, and a transversely penetrating shaft a63 is rotatably connected between the support legs. The shaft a63 passes through the discharge valve a62 and drives its rotation. Shafts b16 and c17 are mounted on the upper side of the frame 1 via bearing seats. Shafts a63 and b16 are driven at their ends by a chain and sprocket. The other end of shaft b16 is also driven by a chain and sprocket to the front press roller 8. A gearbox 10 is mounted on the upper part of the frame 1. Shaft b16 drives the gearbox 10, and the output end of the gearbox 10 drives shaft c17 to rotate via a sprocket and chain mechanism. The end of shaft c17 drives the discharge valve b92. Shafts a63, b16, and c17 rotate synchronously, with one shaft driven by power supplied from the tractor.

[0021] Working principle: When in use, this seeder and fertilizer applicator is installed at the rear of a tractor and towed along the broken ground. The discs 4 arranged in a figure-eight pattern turn the soil and create ridges. At the same time, the soil-breaking plow 31 covers the fallen fertilizer with soil, the leveling plate 5 smooths the top layer of soil, and the front pressing roller 8 performs preliminary leveling of the ridges. Then, the seeding plow 94 plows furrows from the middle of the ridges and sows seeds in the furrows. In this way, sowing and fertilizing are done in separate furrows and are not far apart, which ensures the fertilization effect while avoiding burning the seeds. After sowing, the reversing plow turns the soil to cover the seeds, and finally the rear pressing roller 13 levels the ground to facilitate subsequent mulching.

[0022] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
