Description

Double-ridge rolling insert seeder pulled by walking tractor

technical field

The invention belongs to agricultural machinery, in particular to a corn planter pulled by a small tractor.

Background technique

Existing scattered farmers are engaged in corn sowing operations, and mostly use hand-pressed single-strip inserters or hand-push multi-socket rolling inserters. The farming efficiency of the hand-push multi-nozzle rolling inserter is greatly improved compared with the hand-pressed single-row inserter, but after all, it is powered by human beings. Due to the constraints of human capacity and fatigue caused by continuous output, the farming efficiency is still low. Level. For farmers with more arable land, in order not to miss the farming time, more manpower is required, which will greatly increase the cost of agricultural production. If there is a shortage of manpower, the sowing period will be delayed, and it will be difficult to ensure stable and high yield. The most direct way to solve the above problems is fully mechanized seeding. At present, my country's agricultural production mode is dominated by scattered farmers. It is also not suitable to purchase fully automatic and large-scale seeders. Combining the existing sowing equipment of the current farmers with the walking tractor, the power of the tractor is used to replace the human-driven roll inserter to form a fully mechanized small seeder. It is the optimal way to adapt to the current rural production system. Also do not see at present the technical scheme that hand pushes multi-plug rolling type corn inserter and walk-behind tractor combination.

Contents of the invention

The purpose of the present invention is to provide a double-ridge rolling inserting planter towed by a walking tractor, which is used for sowing corn, soybeans, sorghum and other ridge-grown upland crops, and overcomes the high labor intensity and low sowing speed of human pushing and rolling sowing in the past. Slow, stay on the deficiency of lower farming efficiency.

The planter of the present invention comprises a longitudinal beam connected to the traction pan of a walking tractor, a single ridge roll inserter assembly shaft that crosses the longitudinal beam horizontally and vertically, and the middle part is fixed on the longitudinal beam, and crosses the longitudinal beam horizontally and vertically, and the middle part is fixed on the The assembly shaft of the rolling frame behind the assembly shaft of the inserter on the longitudinal beam, the support wheel installed in the middle and under the rear of the longitudinal beam, is dynamically matched with the two wheels on the assembly shaft of the inserter through the horizontal sleeve fixed on the push rod of the inserter. A rolling inserter, through the horizontal sleeve connected to the pressing roller arm, the two pressing rollers on the pressing roller assembly shaft are dynamically matched, and the screw shaft between the inserting device assembly shaft and the pressing roller assembly shaft and the sleeve is in the axial direction. The position adjustment and locking mechanism is composed of a driving cylinder or a manual lever, a cable and a cable-adjusting support member, and a lifting mechanism for the inserter and the suppression roller.

The casing axial movement locking mechanism between the assembly shaft of the roller inserter and the assembly shaft of the rolling frame and the casing on it is preferably the following structural form:

a. Fix the nut in the tube hole of the tubular assembly shaft, install the rotating screw rod axially locked on the sleeve tube in the casing, extend the end of the screw rod of the casing tube to form a wrench clamping surface or install a rotating handle.

b. Fix nuts with opposite threads in the tube hole of the tubular assembly shaft and the tube hole of the casing respectively, and assemble a screw rod with two sections of reverse threads between the two nuts, and protrude The end of the casing screw rod forms a wrench clamping surface or a rotating handle is installed.

c. A pin column that can be repeatedly installed, disassembled or elastically retracted into the assembly shaft is provided on the peripheral surface of the assembly shaft, and a group of circumferential strip holes matching the pin column are processed on the sleeve.

The preferred lifting mechanism of the inserter and the pressure roller is: connect the upper cable of the inserter to the push rod or roller of the inserter, connect the upper cable of the roller to the roller frame or roller, and install the inserter on the longitudinal beam Pull cable and repression roller pull cable retractable oil cylinder, fix the swing arm shaft perpendicular to the horizontal direction of the longitudinal beam near the oil cylinder on the longitudinal beam, and set the drive shaft swing arm connected with the oil cylinder and the lifting cable connected to the inserter on the swing arm shaft Roll up the cable retractable swing arm of the lifting cable with the suppression roller, and adjust the inserter cable or the suppression roller cable to support the rotating shaft or the pulley according to the pushing direction of the oil cylinder.

In order to compact the planting hole (pit) between the seeder and the front and rear distance between the seeder and the pressure roller after raising the seeder on the ground, the connection state of the lifting cable of the inserter, the lifting cable of the pressing roller and the retractable swing arm of the cable is the oil cylinder. Before starting, the lifting cable of the inserter is in a tensioned state, and the lifting cable of the suppression roller is in a relaxed state, which satisfies the two-stage expansion and contraction of the oil cylinder to lift the inserter and the suppression roller step by step. Or in the structure of stepless expansion and contraction of the oil cylinder, set up the manual lever of the separate traction inserter dragline that is fixed on the longitudinal beam or the arm of the walking tractor.

The positive effects of the present invention are: combining the human-powered rolling seeder with a walking tractor, changing the rolling seeder from human propulsion to tractor traction, and lifting and pulling two seeders to complete synchronous double-ridge sowing, and the duration of sowing is long. It can be extended arbitrarily, realizing the mechanization of sowing suitable for the current rural production mode in our country, and greatly improving the sowing efficiency. The rolling seed inserter and the suppression roller fall to the ground separately and the flexible cable lifts up step by step. The rolling seed inserter and the suppression roller independently float freely with the ups and downs of the ground, and can smoothly sow double ridges even on hillsides.
