Description

A precision seeder for corn ridge mulching, watering and fertilizing

technical field

The invention belongs to the technical field of agricultural machinery manufacturing, and relates to a seeder, in particular to a precision seeder for raising corn ridges and film-covering for watering and fertilizing.

Background technique

At present, there are many types of corn seeders, but their functions are single, and it is impossible to complete the operation of ditching, peritoneum, fertilization, watering, and precision planting at one time. It needs to be completed step by step, especially in drought years, due to insufficient soil moisture, normal seedlings cannot emerge. , delayed the farming time.

Contents of the invention

In view of the problems and deficiencies in the above-mentioned prior art, the object of the present invention is to provide a precision seeder for corn ridge mulching, watering and fertilization, which realizes fertilization, watering, film covering, seeding, etc. during operation. requirements, and by adjusting the position of the ground wheel on the frame to control the depth of sowing corn, by changing the transmission ratio of the transmission to meet the sowing requirements of different plant spacing, and realize precision sowing.

The technical scheme adopted by the present invention to solve the above-mentioned problems is a precision seeder for corn ridges, film-covering, watering and fertilization, including a frame, a water pump, a water tank, a fertilizer box, and a seed box. The water pump and the water tank are installed on the top of the frame. The front position, and the water outlet of the water tank communicates with the water inlet of the water pump, the fertilizer box is installed in the upper middle position of the frame, the seed box is installed in the upper rear position of the frame, and the lower side of the frame is provided by Ridgers, formwork, packers, soil covering devices, and fertilizer openers are installed in sequence from front to back; the fertilizer discharge groove on the fertilizer opener is connected to the fertilizer box through a fertilizer pipe, and the seed discharge of the fertilizer box A ratchet and a small sprocket are installed on the shaft; the ground wheel is installed on the frame through an adjustment rod and a handle, and a large sprocket is coaxially connected to the ground wheel; the small sprocket is connected with the large sprocket through a chain, The seed opener is installed at the lower side of the frame and the rear position, the seeding groove of the seed opener communicates with the seed box through the precision seeder; the drainage groove of the seed opener communicates with the water outlet of the water pump through the water pipe The speed changer, the small sprocket, and the precision seeder are respectively connected by a chain, and the water pump is provided with a one-way valve, and one end of the valve stem stretches into the one-way valve, and the other end of the valve stem is connected with the regulating valve. One end of the screw rod is connected, and the other end of the adjusting screw rod is in contact with the middle of the connecting rod; the lower end of the connecting rod is hingedly connected with the frame, and the upper end is in contact with the blade of the ratchet.

The lower ends of the seeding groove and the drainage groove of the seed opener are respectively equipped with blocking plates, and the two blocking plates are connected by rods.

The working principle of a precision seeder for corn ridge mulching, watering and fertilizing according to the present invention is:

When the seeder starts to work driven by the tractor, the first step is to ridge the ground with the ridge board, then spread the plastic film wound on the formwork on the ridge, and then the pressing wheel will spread the mulch film on the ridge After compaction, the soil covering device will turn the soil over the edge of the mulching film to realize the mulching operation; in the second step, the opener will open a groove, and the fertilizer will flow through the fertilizer box through the fertilizer pipe under the drive of the ratchet shaft. It falls into the groove opened by the opener to realize the fertilization operation; in the third step, every time the ratchet rotates a tooth, the ratchet gives a force to the adjustment valve stem, and then the one-way valve is opened under the action of the valve stem, and then After the water in the water tank is pressurized by the water pump, it enters the drainage groove of the seed opener through the water pipe to flush out the interlocking blocking piece, so as to realize water application and seed discharge operations. The position of the ground wheel in the frame can be adjusted by the handle and the adjustment rod to realize the operation of different planting depths, and the continuous planting of different plant spacing can be realized by changing the transmission ratio of the transmission.

The beneficial effect of the present invention is that continuous planting can be realized when the precision seeder is working, the productivity is high, and corn planting of different depths can be realized by adjusting the position of the ground wheel in the frame; the transmission ratio of the transmission can be adjusted Realize the planting requirements of different plant spacing; realize the cooperation requirements between fertilization and water application of corn; can greatly save labor and improve operation quality. the
