Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural planting, and particularly relates to a planting device for high-yield peanuts and a planting method thereof. Background Art

[0002] Currently, the peanut planting device is provided with a soil loosening and seeding structure. The soil loosening structure is generally completed by a rotary tillage structure. This method causes greater disturbance to the soil. If peanuts are intercropped, the roots of the intercropped crops will also be damaged. Therefore, an air jet soil loosening device has been invented, which usually includes an air compressor, an air pressure tank / energy storage tank, and a soil loosening head. The high-pressure air passes through the soil loosening head to perform air explosion on the soil layer, so as to generate gaps in the soil, which not only plays the role of loosening the soil, shakes the compacted soil open, but also increases the air permeability of the soil, is beneficial to the growth of plants, and at the same time causes less disturbance to the soil and does not damage the roots of the intercropped crops. However, the air jet soil loosening device usually operates intermittently. After inserting the soil loosening head into the soil, air explosion is carried out and then moved to the next point for insertion and air explosion, and continuous operation cannot be achieved. Summary of the Invention

[0003] The purpose of the present invention is to provide a planting device for high-yield peanuts and a planting method thereof to solve the problems existing in the prior art.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] A planting device for high-yield peanuts, including a frame, on which are sequentially installed from front to back:

[0006] Soil loosening mechanism: including an air compressor, a support rod, and a driving device. The air compressor is sequentially connected with an air pressure tank and an air explosion soil loosening head through an air pipe. The support rod is hinged on the frame. The support rod is hinged with an installation cylinder. The top end of the installation cylinder is hinged with a driving rod and a driven rod. The other end of the driving rod is fixed on the output shaft of the driving device. The other end of the driven rod is hinged on the frame. The air explosion soil loosening head is fixedly connected to the installation cylinder;

[0007] Seeding mechanism: including a seed box, a furrow opener, a soil covering plate, and a press wheel.

[0008] Further, wheels are installed at the rear end of the frame. A support shaft is fixed at the bottom of the frame near the front end. A side plate is fixed on the frame. A cross shaft is fixed on the side plate. A proximity switch is installed on the side plate.

[0009] Further, the bottom end of the installation cylinder is open and a flange is welded at the bottom end. Trunnions are provided on the outer walls on both sides of the installation cylinder. An extension rod is welded at the top end of the installation cylinder.

[0010] Further, one ends of the driving rod and the driven rod are jointly hinged on the extension rod. The other end of the driven rod is hinged on the frame through the cross shaft and the side plate.

[0011] Further, the air-burst soil loosening head is an air jet soil loosening device. A flange is fixed on the outer wall of the soil loosening head. After the top end of the soil loosening head is inserted into the installation cylinder, it is bolted to the bottom end of the installation cylinder through the flange.

[0012] Further, there are two support rods. The two support rods are jointly hinged on the support shaft, and the other ends of the two support rods are respectively hinged on two trunnions.

[0013] Further, valves are installed at both the input end and the output end of the air pressure tank.

[0014] Further, the furrow opener is a disc furrow opener. The furrow opener is fixed on the frame through a connecting piece. A conduit is welded on the back soil surface of the furrow opener by the connecting piece. The output end of the seed box communicates with a seed metering device, and the output end of the seed metering device is inserted into the conduit through a hose.

[0015] Further, the soil covering plate is located behind the furrow opener. The soil-facing surface of the soil covering plate is arc-shaped. A vertical rod is welded on the soil covering plate. The vertical rod is fixed on the frame through a connecting piece. A horizontal rod is welded on the vertical rod. A retaining ring is fixed at the top end of the sliding rod. A spring is sleeved on the sliding rod between the retaining ring and the horizontal rod. The two ends of the spring are respectively fixed on the retaining ring and the horizontal rod. The pressing wheel is fixed at the bottom end of the sliding rod.

[0016] A planting method for a high-yield peanut planting device includes the following steps:

[0017] (1) Put peanut seeds into the seed box and hitch the frame to a tractor.

[0018] (2) Start the air compressor, supplement compressed air into the air pressure tank, and electrically connect the valve at the output end of the air pressure tank with a proximity switch.

[0019] (3) Start the tractor and the driving device. During the walking process, the driving device drives the air-burst soil loosening head in the installation cylinder to reciprocate up and down through a driving rod, and the driven rod rotates accordingly. When the working end of the air-burst soil loosening head inserts into the soil, the driven rod rotates to the front of the proximity switch, triggering the valve at the output end of the air pressure tank to open. The compressed air in the air pressure tank enters the air-burst soil loosening head and is instantly discharged into the soil to form an air-burst effect for soil loosening. The support rod of the driven rod causes the air-burst soil loosening head to swing slightly back and forth.

[0020] (4) After the furrow opener opens a furrow, the peanut seeds in the seed box fall into the furrow through the seed metering device, the hose, and the conduit, and then the soil covering plate covers the soil, and the pressing wheel presses the soil.

[0021] The present invention has the following beneficial effects:

[0022] 1. The present invention can carry out continuous air jet loosening of the soil, followed by furrowing, sowing, soil covering, and rolling. It not only plays the role of loosening the soil, breaking up the compacted soil, but also increases the air permeability of the soil, which is beneficial to the growth of plants. At the same time, it causes little disturbance to the soil and does not damage the roots of the intercropped crops.

[0023] 2. The soil loosening mechanism of the present invention enables the air explosion soil loosening head to reciprocate up and down through the coordinated movement of the hinged support rod, drive rod, and driven rod. As a result, the air explosion soil loosening head repeatedly inserts into the soil for air explosion, without the need to stop midway, achieving continuous operation of the soil loosening mechanism, thus adapting to continuous sowing operations.

[0024] 3. The rolling wheel of the present invention can perform profiling rolling on the soil covering, thereby adapting to the undulations of the soil and enhancing the rolling effect. BRIEF DESCRIPTION OF THE DRAWINGS
