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 forcefully eject the granules 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, the injection mechanism is equipped with a rotor for injection, a drive section for driving the rotor to rotate, and a guide extending vertically from the delivery section to the rotor, a recess is formed on the outer periphery of the rotor into which the agricultural materials can enter, the rotor is configured to rotate to eject the agricultural materials that have entered the recess, and the guide has an oblique guide surface that approaches the outer periphery of the rotor as it approaches the outer periphery.
  • the rotor is wider than the storage section when viewed in the direction of the rotor's rotation axis.
  • the lower part of the injection mechanism is formed with an injection port that opens downward.
  • an abnormality detection means is provided to detect whether the agricultural material is retained inside the injection mechanism.
  • the injection mechanism is provided with an escape section that prevents the agricultural material from being retained inside the injection mechanism.
  • the guide body is made of an elastically deformable material, and that the guide body also serves as the escape section that allows the agricultural materials to escape by being pushed and deformed by the agricultural materials that are retained.
  • the guide body which also serves as an escape section, elastically deforms, allowing the jammed agricultural materials to escape.
  • FIG. FIG. FIG. 2 is a side view of the seeding device.
  • FIG. FIG. FIG. 4 is a flowchart of a control operation.
  • Figures 1 and 2 show a work system that supplies agricultural materials to a field.
  • the work system includes a seeding device H, which is an example of an agricultural material injection device according to the present invention, and an unmanned aircraft 2 known as a drone.
  • the aircraft 2 is configured to be able to fly independently.
  • the aircraft 2 has a main body 4, multiple propellers 5, and multiple arms 6.
  • Hopper 7 has a storage space surrounded by side walls. An opening 10 is formed at the top of the storage space, leaving it open at the top. A large number of seeds N can be added through opening 10.
  • the bottom of hopper 7 is provided with a flow-down guide section 11 that tapers downward. At the bottom of flow-down guide section 11 is formed a discharge section 12 that can discharge the stored seeds N downward.
  • the opening 10 at the top of hopper 7 is closed by a removable lid 13 after the seeds N have been added.
  • 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 is equipped with a casing 18 that surrounds the outer periphery, an injection rotor 19 located inside the casing 18, an injection electric motor (hereinafter referred to as the second motor) M2 that serves as a drive unit that drives the rotor 19 to rotate, and a guide body 20 that extends vertically from the payout unit 8 to the rotor 19.
  • the second motor M2 an injection electric motor (hereinafter referred to as the second motor) M2 that serves as a drive unit that drives the rotor 19 to rotate
  • a guide body 20 that extends vertically from the payout unit 8 to the rotor 19.
  • a remote control device Q is provided to manage the operating state of the sowing device H via wireless communication.
  • the sowing device H is provided with a control unit 23 that controls the operation of the first motor M1 and the second motor M2, a first speed sensor 24 that detects the rotational speed of the unwinding roller 14 driven by the first motor M1, and a second speed sensor 25 that detects the rotational speed of the rotating body 19 driven by the second motor M2.
  • the sowing device H is equipped with an abnormality detection means 100 that uses the control unit 23 to detect whether or not seeds N are retained inside the injection mechanism 9.
  • the abnormality detection means 100 also detects whether or not seeds N are retained based on the rotation state of the rotor 19.
  • the operator of remote control device Q can recognize that the operation is abnormal through the notification process, and can then take appropriate measures.
  • a storage section for storing a large number of seeds N may be provided inside the radial direction of the rotor 19, and a configuration may be used in which, of the seeds N stored as the rotor rotates, a single seed N or a small amount of seeds N that can be sown at one sowing point is automatically supplied to the outer periphery of the rotor 19.
  • a separate storage section, flow guide section, etc. are not required, and the configuration can be simplified.
