Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery, and specifically relates to a hydraulic drip irrigation belt peanut planter. Background Technology

[0002] Peanut planters with drip irrigation tape are common in existing peanut planters. The drip irrigation tape is laid on the ground as the planter moves, and it cannot be automatically disconnected when the planter changes lanes, limiting the planter's operating speed. Currently, there is no machine that automatically cuts off the drip irrigation tape. In addition, existing peanut planters use a nozzle-type planting disc, which often results in soil residue on the nozzles, affecting planting quality. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a hydraulic drip irrigation tape-breaking peanut planter that is compact in structure, easy and flexible in tape breaking, and reliable in function.

[0004] The technical solution adopted by this invention to solve the technical problem is as follows: A hydraulic drip irrigation tape peanut planter includes a frame, a suspension bracket, a contour wheel, a seed box, a seed tray fixing frame, a drip irrigation tape chuck frame, a drip irrigation tape chuck, a press wheel frame, a press wheel axle, and a press wheel. Its characteristic is that two seed tray fixing frames are fixed on both sides of the frame at the middle. The inner side plate of the seed tray is fixed to the inner frame of the seed tray fixing frame with fixing screws. The seed tray axle is fixed to the middle of the outer frame of the seed tray fixing frame with a fixing nut. The seed tray is fastened to the inner side plate on the seed tray axle. Multiple triangular pressing devices are provided on the outer circumference of both seed trays. Two vertical shaft frames are provided at the rear end of the two seed tray fixing frames. Seed dispensing tongue soil-removing bearings are mounted on the inner side of the shaft frames, and soil-removing devices are mounted on the seed dispensing tongue soil-removing bearings at the root of the pressing devices. A fixing frame is provided above the rear end frame of the frame, and a hydraulic cutter is fixed to the outer surface of the fixing frame with fastening bolts. The device includes a hydraulic tape-breaking cutter. The hydraulic tape-breaking cutter consists of a hydraulic tape-breaking cutter plunger located above the housing, a return spring surrounding the plunger, a hydraulic tape-breaking cutter guard located below the plunger, and a blade fixedly mounted below the plunger within the guard. The blade's width is parallel to the rear frame of the machine and is greater than the diameter of the drip irrigation tape. A hydraulic tape-breaking cutter oil pipe is led out from the top of the housing, and a return oil pipe is led out from the lower middle of the housing. The hydraulic tape-breaking cutter oil pipe connects to the outlet port of the hydraulic tape-breaking cutter lifting control valve, and the return oil pipe connects to the inlet port of the same valve. One end of the hydraulic tape-breaking cutter lifting control valve is fixedly mounted on a diverter valve mounting bracket, and the other end is connected to a control handle using a connecting screw.

[0005] The beneficial effects of this invention are as follows: The hydraulic drip irrigation tape cutting peanut planter uses a hydraulic device to automatically cut the drip irrigation tape, making the peanut planter flexible and time-saving when changing rows for planting, improving work efficiency, eliminating the need for auxiliary workers, and reducing expenses. A soil-removing device is installed at the pressure nozzle of the planting disc, ensuring the planting quality of the peanut planter, increasing peanut yield, and increasing profits. The planter has added a suspension clip, improving terrain adaptability, and allowing one tractor to drive multiple planters. The entire peanut planter has a compact structure, is convenient and flexible to use, and is reliable in function. Attached Figure Description

The hydraulic tape cutter lifting control valve is connected to the seeder lifting control valve via connecting pipe 22.

[0016] The working process of the hydraulic tape-breaking peanut planter is as follows: Before operation, push the hydraulic tape-breaking cutter control handle 17-1 forward to connect the inlet hole 17-2-8, allowing hydraulic oil to enter the planter lifting control valve 18 through the connecting pipe 22 between the hydraulic tape-breaking cutter lifting control valve and the planter lifting control valve. Push the planter lifting control valve handle 18-1 backward to connect the oil inlet hole 3 18-2-5 and the oil outlet hole 2 18-2-6, allowing hydraulic oil to flow through the lifting oil supply pipe 18-4 to lift the planter. When the planter is lifted to a certain height, connect the return oil pipe 18-5 to push the flow divider valve plunger 2 18-2, connecting the oil inlet hole 4 18-2-7 and the oil outlet hole 3 18-2-8. The hydraulic oil flows into the oil storage tank through the drain pipe 2 18-7 and the return oil storage tank pipe 21, keeping the planter in a suspended state. The hydraulic oil in the planter lifting control valve 18 flows back to the oil storage tank through the drain pipe 1 18-6.

[0017] To install the drip irrigation tape, turn the lever 8-5 clockwise to loosen the fastening screw clip 8-3, remove the auxiliary plate 8-2, install the drip irrigation tape, then install the auxiliary plate 8-2 again. Turn the lever 8-5 counterclockwise to secure the auxiliary plate 8-2. Place the drip irrigation tape chuck 8 back onto the drip irrigation tape chuck holder 9, extend the drip irrigation tape head, pass it through the drip irrigation tape guide ring 16, and extend it from between the drip irrigation tape laying auxiliary wheel 12 and the lower drip irrigation tape laying auxiliary wheel 13. The tractor enters the ridge, and the seeder is pushed forward to raise and lower. Control valve handle 18-1 connects oil inlet port 5 18-2-9, oil inlet port 6 18-2-10, and oil outlet port 4 18-2-11. Hydraulic oil from the oil pump and the hydraulic oil in the suspension machine flow into the oil storage tank through the drain port, lowering the seeder and starting operation. During operation, the compaction wheel 10 compacts the seeding holes and rotates simultaneously, driving the drip irrigation belt auxiliary wheel 12. The drip irrigation belt auxiliary wheel 12 drives the lower drip irrigation belt auxiliary wheel 13 to rotate, causing the drip irrigation belt to move synchronously. Okay, proceed with laying the drip irrigation tape; upon reaching the edge of the field, move the hydraulic tape-cutting cutter control handle 17-1 backward. Hydraulic oil enters the hydraulic tape-cutting cutter device housing 15 through the oil inlet 17-2-5 and the connected hydraulic tape-cutting cutter oil pipe 17-4, the oil outlet 17-2-6 and the connected hydraulic tape-cutting cutter return oil pipe 17-5, pushing the hydraulic tape-cutting cutter plunger 15-2, ejecting the hydraulic tape-cutting cutter blade 15-3, cutting the drip irrigation tape. After that, the hydraulic oil flows through... The hydraulic oil from the return pipe 17-5 of the hydraulic tape cutter enters the hydraulic tape cutter lifting control valve 17, pushing the flow divider plunger 17-2 forward, connecting the supply pipe 17-4 and the discharge pipe 17-6 of the hydraulic tape cutter. Then, through the return pipe 21, the hydraulic oil in the housing 15 of the hydraulic tape cutter device flows back into the storage tank. Under the push of the spring 17-2-2, the hydraulic tape cutter plunger 15-2 and the cutter blade 15-3 return to their original positions. Simultaneously, through the inlet port 17-2-5, the outlet port 17-2-6, and the oil pipe 22, the seeder lifting control valve 18 is reconnected. Moving the handle 18-1 of the seeder lifting control valve allows for repeated operation. During sowing, the pressing device 5-1 and the seed metering tongue 5-2 on the sowing tray 5 are prone to soil accumulation, which affects the sowing effect. The soil removal bearing 6-4 installed on the sowing tray frame 6 allows the seed metering tongue 5-2 to remove soil through the vibration generated by the downward rebound when it passes the soil removal bearing 6-4 on the seed metering tongue.
