Definitions

  • the present invention relates to an agricultural material injection device for supplying granular agricultural materials, such as seeds and fertilizer, to a field.
  • a seed sower which is an example of an agricultural material injection device, has been configured as follows. That is, the device includes a tank for storing seeds, which are an example of agricultural materials, a delivery mechanism for delivering the seeds from the underside of the tank, a shooter unit for shooting the delivered seeds into a field, and a cylindrical guide body extending in the vertical direction for guiding the seeds delivered by the delivery mechanism to the shooter unit.
  • the shooter unit includes a rotor having multiple radially extending blade bodies and driven to rotate at high speed, and is configured so that the seeds delivered by the delivery mechanism and falling downward through the inside of the guide body are ejected downward by the blade bodies of the rotor (for example, see Patent Document 1).
  • the blade body needs to eject the agricultural materials forcefully downward, so the rotor needs to be rotated at high speed.
  • the agricultural materials fall freely relative to the rotor body rotating at high speed, they do not necessarily enter the upstream side of the blade body in the direction of rotation; for example, the agricultural materials may become caught between the tip of the blade body and the inner surface of the cylindrical guide body.
  • the blade body will press the agricultural materials against the inner surface of the guide body with too much force, causing the agricultural materials to be crushed, or that the agricultural materials will become jammed when they are caught between the blade body and the guide body, causing a blockage that makes it impossible to rotate and causing the rotation to stop.
  • the agricultural material injection device is characterized in that it is equipped with a storage section for storing granular agricultural materials, a delivery section for delivering the agricultural materials stored in the storage section, and an injection mechanism for injecting the agricultural materials delivered by the delivery section to a destination, and the injection mechanism is equipped with a gas compression section for compressing gas and a gas ejection section for ejecting the compressed gas to the outside, and is configured to eject the agricultural materials by gas ejected from the gas ejection section.
  • compressed gas is forcefully ejected from the gas ejection section of the injection mechanism to the outside.
  • the gas forcefully ejected to the outside blows agricultural materials away and supplies them to the field.
  • the ejected gas it is possible to move the materials as linearly as possible through the air and supply them to the target location while being less susceptible to the effects of outside winds, etc.
  • the gas compression section is provided with a cylinder tube, a piston that slides within the cylinder tube, and a slide operation mechanism that slides the piston to compress the gas within the cylinder tube.
  • the slide operation mechanism includes a spring that can be compressed and expanded along the sliding direction of the piston, a rack gear provided on the piston, a sector gear that meshes with the rack gear and moves in a direction that compresses the spring, and an actuator that rotates the sector gear.
  • the payout section 8 is provided with a payout roller 14 at a position facing the discharge section 12 of the hopper 7.
  • the payout roller 14 is surrounded by a payout case 15.
  • the payout case 15 is open at the location facing the discharge section 12 of the hopper 7 and at the lower location.
  • the injection mechanism 9 includes a gas compression section 20 that compresses gas, and a gas ejection section 21 that ejects the compressed gas to the outside, and is configured to eject seeds N by the gas ejected from the gas ejection section 21.
  • the gas compression section 20 is provided with a cylinder tube 22, a piston 23 that slides within the cylinder tube 22, and a slide operation mechanism 24 that slides the piston 23 to compress the gas within the cylinder tube 22.
  • the slide operation mechanism 24 includes a spring 25 that can be compressed and expanded along the sliding direction of the piston 23, a rack gear 26 provided on the piston 23, a sector gear 27 that meshes with the rack gear 26 and moves in a direction that compresses the spring 25, an electric motor 28 that acts as an actuator to rotate the sector gear 27, and a battery 29 that supplies power for driving the electric motor 28.
