Capsule seeding device

Technical Field

The invention relates to the technical field of agricultural machinery automation, in particular to a capsule seed sowing device.

Background

In recent years, potatoes play an increasingly important role in guaranteeing the safety of grains, and become the fourth main grain behind rice, wheat and corn. With the rapid development of the potato industry, the market demands for mature, reliable and technically advanced potato planting machinery are urgent. At present, potatoes have two seeding modes, one mode is direct seeding after cutting according to potato bud eyes, the mode has realized mechanized seeding, the seeding quality of the potato seeding machine is directly related to the growth and the final yield of the potatoes, and the seed metering device is the most key factor for determining the seeding quality of the potato seeding machine. At present, common seed sowing devices on potato seeders are provided with spoon chain type, spoon disc type, needle punching type, belt type and other implementation modes. The spoon chain type seeding mode is a common seeding mode in the prior art, but the miss-seeding rate is high in the seeding process, the spoon disc type seeding uniformity is poor, the potato seeds are damaged in the needle punching mode, and the belt type seeding mode has the problems of complex structure, inconvenient row spacing and plant spacing adjustment and the like; and the other method is that after the potatoes are cut into pieces, the potatoes are sprouted, and the seedlings are sown after growing to about 1-3cm, and the seedlings are required to be upward in the bud-sowing mode, and the existing sowing modes all adopt manual operation, so that the result is more than half. The main reason why mechanical sowing can not be adopted is that potatoes are often very troublesome in the planting process, and when the existing potato sowing machine is used for sowing, the orientation of potato buds can not be ensured, so that the growth of the potatoes can be influenced.

During specific operation, firstly, a rotating blade on the rotating material cutting and pushing mechanism on the right side of the rack is contracted to the right end of the rack, then the capsule seed row is positioned and placed on the rack, and the opening-closing type bin door of the hole sowing mechanism 4 on the left side of the rack is aligned to the position of soil to be sowed; rotating a rotating blade on the material cutting and pushing mechanism to enable a blade edge of the rotating blade to be correspondingly arranged along the middle position of the width direction of the capsule seed box, starting an electric push rod to enable the rotating blade to cut the air chambers of the capsule seeds in the capsule seed row, and cutting the air chambers of the capsule sealing covers of the capsule seeds in the capsule seed row from right to left by the blade edge of the rotating blade to realize the contact of bud eyes and air; after the rotating blade is retracted in the original way by the electric push rod, the rotating motor is started to rotate the rotating blade (the rotating angle is 90 degrees) to be opposite to the outer side surface of the capsule seed row, the capsule seeds are pushed to move leftwards in sequence from right to left by the rotating blade, when a single capsule seed enters the upper end limiting containing cavity of the preset blanking channel, the limiting loading of the single capsule seed is realized, and the electric push rod pauses the pushing of the capsule seed; the single capsule seeds in the limiting and accommodating cavity are buffered and discharged through the suction device, and are sowed in the soil through the opening-closing type bin door (the situation that a plurality of capsule seeds are extruded on the opening-closing type bin door and are easy to leak or damage is easily caused by the plurality of capsule seeds can be effectively avoided); then starting the electric push rod to push the next capsule seed to enter the limiting accommodating cavity, and moving the rack to enable the opening-closing type bin door to align to the position of soil to be sowed by a new legal person to continue to discharge; and repeating the steps of pushing by the electric push rod and discharging by the opening-closing type bin door until all the capsules in the capsule row are sown, and then putting a new capsule row.

In another embodiment, different from the above embodiments, a plurality of support portions 12 are provided behind the vehicle body 11; the spacing between the plurality of support portions 12 is adjustable; specifically, the supporting parts 12 are connected by an adjustable limiting device, such as a screw and nut connecting component structure.

The automatic capsule sowing machine is compact in structure, more reasonable in arrangement, more economical and practical, capable of achieving effective one-by-one accurate automatic capsule sowing, and suitable for application of agricultural industrialization.
