Japanese Patent Laid-Open No. 5-49312 (paragraph [0013], FIGS. 2 and 5)

There is a case where seed meal (hereinafter referred to as “iron coating seed meal”) that has been subjected to iron coating treatment so as not to cover the soil is supplied to the field by the above-described powder supply apparatus.
Especially when supplying iron-coated seeds, the feeding guide should be made of a metal or other hard material so that the sliding of the powdered material against the feeding guide is good, or the abrasion of the feeding guide due to contact with the powdered material is less likely to occur. If it is made of a material, it is easy to generate a sound in which the feeding guide and the seed rub against each other.

  The purpose of the present invention is to provide a powder supply device capable of supplying powder in a spot-spreading supply form with good spot-spreading accuracy, even if the feed guide is configured so that the powder is slippery or difficult to wear, An object of the present invention is to obtain a sound that can suppress a sound caused by friction between the feeding guide and the granular material.

According to the first aspect of the present invention, the granular material stored in the granular material tank is intermittently paid out by a set amount by a feed-rotating feeding rotary body provided with a feeding recess on the peripheral surface, and dropped and supplied to the field. A powder and particle supply device,
The granular material that has entered the feeding concave portion on the upper end side of the feeding rotary body is retained in the feeding concave portion until the feeding concave portion moves to the lower end side of the feeding rotary body and discharges the granular material. Providing a feeding guide located along the peripheral surface of the feeding rotating body so as to guide the granular material;
The feeding guide, forming a guide body made of a metal plate in which formed a guide surface acting, the guide surface of the guide body so as to sound absorption or damping action to the guide body to the granular material And a sound absorbing material or a vibration damping material provided in close contact with the surface opposite to the side.

According to the configuration of the first aspect of the invention, the granular material that has entered the feeding recess on the upper end side of the feeding rotating body moves to the lower end side of the feeding rotating body while being guided by the feeding guide so as to stay in the feeding recess. Since it moves to the lower end side of the rotating body and then is discharged from the feeding recess, the granular material that is intermittently fed out by the set amount by the feeding rotating body at a set amount from the feeding recess at the lower end side of the feeding rotary body It can be dropped and supplied to the field in a state of being dropped into the field in a dotted manner.
Even if the guide body of the payout guide is made of a hard material such as a metal plate, the powder body to be supplied is not easily worn by contact with the powder body, such as good sliding of the powder body. Even if a rubbing noise occurs between the guide body and the granular material such as iron coating seeds, the air vibration caused by the sound generation is attenuated by the sound absorbing material, or the vibration of the guide main body due to the sound generation is reduced. It can be absorbed by the damping material to suppress the transmission of the generated sound to the periphery.

  Therefore, the iron coating can be applied to the field with good spotting accuracy, while the sliding of the powder with respect to the feeding guide is improved or the wear of the feeding guide is suppressed. Even if it is a granular material such as seeds, the work can be performed in a good state in which sound generated in the periphery due to friction between the guide body and the granular material is suppressed.

According to the configuration of the first aspect of the present invention, the feeding guide capable of effectively preventing the wear of the guide surface can be obtained at a low cost by the metal plate, and the rubbing sound between the guide main body and the granular material is obtained as a sound absorbing material or It can suppress effectively by contact | adherence with a damping material and a guide main body.

  Therefore, the guide body of the feeding guide can be provided with excellent durability that is difficult to wear out at low cost, while working in a good state of feeding the powder body that effectively suppresses the rubbing noise between the guide body and the powder body. Can be performed.

In the second aspect of the invention , the side of the feeding guide located on the upper side in the rotating direction of the feeding rotary body swings in the radial direction of the feeding rotary body with the side positioned on the lower side of the feeding rotary body rotating direction as the swing fulcrum side. As described above, the feeding guide is supported.

According to the second aspect of the present invention , when the granular material that has entered the feeding recess on the upper end side of the feeding rotating body moves along the movement path that receives the guiding action by the feeding guide, it is opposite to the swinging fulcrum side of the feeding guide. It enters the movement path from the side where the side exists, and moves along the movement path toward the side where the swing fulcrum side of the feeding guide exists. Therefore, even if the granular material when entering the moving path is still insufficiently accommodated in the feeding concave portion and a part of the granular material protrudes outward from the feeding concave portion, the feeding guide The side opposite to the swinging fulcrum side is pressed toward the side away from the feeding rotating body, and enters while being easily swung. The granular material moving along the moving path toward the side where the swing guide fulcrum side of the feeding guide is present is guided by the feeding guide in a state where the pressing action by the feeding guide is gradually strengthened, and the bulky state is eliminated. Therefore, the friction between the granular material moving along the moving path that receives the guiding action by the feeding guide and the feeding guide can be suppressed to a weak state.
Accordingly, it is possible to suppress the friction between the feeding guide and the granular material from the surface of the support structure that supports the feeding guide so as to swing as described above, and to suppress the rubbing sound from this surface. .

In the third aspect of the invention , a flow-down guide plate that causes the granular material stored in the granular material tank to flow down to the feeding rotary body is disposed above the feeding rotary body inside the feeding case that houses the feeding rotary body. Arranged and provided,
A connecting means for detachably attaching the flow guide plate to the feed case is disposed on the feed case so as to be positioned above the flow guide plate in a state of being attached to the feed case in a predetermined mounting posture. The support body provided and the flow guide plate are configured to be engaged with the support body by an operation of inserting the flow guide plate into the inside of the feeding case from above, and disposed above the guide surface of the flow guide plate And a connecting hook provided on the flow guide plate.

According to the configuration of the third aspect of the present invention , when the flow guide plate is inserted into the inside of the feeding case and incorporated from above, the coupling hook can be engaged with the support body by the incorporation operation to bring the coupling means into the coupled state. At this time, the connecting hook and the support are viewed from above the feeding case to know the engagement state of the connecting hook and the supporting body, and it is confirmed that the connecting means is in the predetermined connecting state, and the flow guide plate is used as the feeding case. It can be connected appropriately.

  Therefore, simply by inserting the flow guide plate into the feeding case, it is possible to obtain a state in which the flow guide plate is appropriately attached to the feed case and the powder particles are properly fed by the feed rotating body.

In the fourth aspect of the present invention , the flow guide plate is attached to the flow guide plate so that a slide body that acts on the powder particles that have entered the feed recess of the feed rotary body is assembled together with the flow guide plate inside the feed case. It is attached.

  FIG. 10 is an explanatory view showing the operation of the feeding guide 80. FIG. 11B is a perspective view of the feeding guide 80 attached. As shown in these drawings and FIG. 5, the feeding guide 80 includes a guide surface 81 positioned along the peripheral surface 52 s of the feeding rotator 52, and enters the feeding recess 58 of the feeding rotator 52 to feed the feeding rotator 52. The guide surface 81 guides the seed pod a that moves to the discharge point Z that is installed on the lower end side. In other words, the feeding guide 80 allows the seed pod a to be fed from the feeding recess 58 passing through the brush portion 54a of the lower-side scraped body 54 to the discharge point Z even if the feeding recess 58 is turned sideways or downward. It stays in the feeding recess 58 without spilling from the recess 58, and when the feeding recess 58 reaches the discharge point Z and faces downward, the seed soot a is guided to the seed soot a so as to fall and be discharged from the feeding recess 58. Works.

  As shown in FIG. 5, the scraper 53 on the upstream side includes a brush support portion 53b supported by the lower end portion of the flow guide plate 57, and a brush portion 53a implanted in the brush support portion 53b. It is configured. The downstream scraper 54 includes a brush support portion 54b supported by the feeding case 51 via a rotation support shaft 72, and a brush portion 54a implanted in the brush support portion 54b. . FIG. 9 is an explanatory view showing the operation of the downstream scraper 54. As shown in this figure and FIGS. 5 and 6, the pair of slicing bodies 53, 54 is sliced by the brush parts 53 a, 54 a against the seed pod a that has entered the feeding recess 58 of the feeding rotary body 52.

Accordingly, the powder and granular material supply device A is fed and rotated by the power transmitted by the drive mechanism D to the drive gear 86 provided to be rotatable integrally with one end portion of the rotation support shaft 59 so that the rotation support shaft 59 is rotationally driven. The body 52 is driven by the rotation support shaft 59 in the rotation direction G, and is set by the volume of the feeding recess 58 through the supply space 50 by the feeding rotating body 52 that rotates the seed pod a stored in the powder tank 32. The set amount is intermittently fed out, and the seed pod a fed out by the feeding rotary body 52 is dropped onto the field and supplied in the form of spot sowing supply.

That is, the seed soot a stored in the granular material tank 32 and flowing down from the granular material circulation holes of the lattice body 45 attached to the funnel portion 32 a is caused to flow down to the supply space 50 by the flow guide by the flow guide plate 57 and stay. Let By driving the feeding rotary body 52 in the rotation direction G , each feeding recess 58 moves between the supply space 50 and the discharge point Z. When the feeding recess 58 is located in the supply space 50, the seed pod a of the supply space 50 is introduced and accommodated. The feeding recess 58 containing the seed pod a passes through the brush portions 53a and 54a of the upper and lower side scraped bodies 53 and 54 and is subjected to the scraping action by the brush portions 53a and 54a. Move down the moving path. At this time, even if the feeding recess 58 is turned sideways or downward, the seed soot a does not spill out of the feeding recess 58 due to the guiding action of the guide surface 81 of the feeding guide 80 on the seed soot a. When the feeding recess 58 reaches the discharge point Z, the feeding recess 68 faces downward and the guiding action by the feeding guide 80 is released, so that the seeds a stored in the feeding recess 58 are transferred from the feeding recess 58 to the inside of the cylindrical body 56. Fall into. The seed pod a that has fallen from the feeding recess 58 falls on the dropping path formed by the cylindrical body 56 while being wind-shielded by the cylindrical body 56 so as not to receive and disperse the wind. It falls to the field slightly behind and slightly to the side.

  As shown in FIGS. 5, 7, and 11, the feeding guide 80 includes a guide main body 82 that forms a guide surface 81, and a damping material provided on the opposite side of the guide main body 82 from the side on which the guide surface 81 is located. 83.

FIG. 11A is a perspective view of the feeding guide 80 in a removed state. FIG. 11B is a perspective view of the feeding guide 80 attached. As shown in these drawings and FIG. 5, the guide main body 82 includes a curved portion that forms a guide surface 81 along the peripheral surface 52 s of the feeding rotary body 52 , and a bent end portion 82 a that constitutes a connecting portion to the support 90. And a linear portion 82s positioned between the bent end portion 82a and the curved portion. Feeding guide 80 is constituted by a stainless steel plate bent end portion 82a to the lower end 90a is connected by a connecting screw 91 of the support 90 extending from the brush supporting lifting portion 54b of the downstream side of the scraping member 54 in the downward orientation It is. The guide main body 82 includes a bent guide portion 82b that makes it easy for the seed pod a to enter between the rotary body 52 and the guide main body 82. The damping material 83 is in close contact with the entire surface or almost the entire surface of the guide body 82 excluding the bent end portion 82a and the bent guide portion 82b of the surface of the guide body 82 opposite to the side on which the guide surface 81 is formed. It is made of a plate rubber. A notch 82c into which the guide plate 84 enters is formed on both lateral sides of the end of the guide main body 82 on the upper side in the rotation direction of the feeding rotary body. On both sides of the damping material 83, notches into which the guide plate 84 enters are formed in the same manner as the notches 82c of the guide body 82.

  Therefore, in the payout guide 80, the seed potato a is a seed moth that has been subjected to the iron coating process, and thus a sound is generated in which the seed moth a and the guide surface 81 rub against each other. The feeding guide 80 performs a guiding action on the seed pod a while absorbing the vibration of the guide body 82 due to the generation of sound by the damping material 83.

  Since the feeding guide 80 is supported by the support 90 at the bent end portion 82a on the lower end side of the guide body 82, the upper side of the feeding guide 80 in the feeding rotating body rotation direction with respect to the support 90 is the feeding rotating body rotation direction. The lower rotary side is in a state of swinging in the radial direction of the feeding rotary body 52 with the side positioned on the lower side as the swing fulcrum side.

  Therefore, after the seed soaker a accommodated in the feeding recess 58 passes through the brush portion 54a of the downstream scraper 54, it enters a moving path that receives a guiding action by the feeding guide 80, and this moving path is set as a discharge point Z. Move towards. Even if the seed pod a entering the movement path is in a bulky state in which a part of the seed potato a protrudes outside the feeding recess 58 due to a scraping failure caused by the scraping bodies 53 and 54, the feeding guide 80 rotates the feeding rotary body. The side located on the upper side in the direction and opposite to the swinging fulcrum side is easily pressed and swung to the side away from the feeding rotary body 52, so that the seed surface a and the guide surface 81 of the guide main body 82 can be obtained. It enters the movement path while suppressing the friction of each other to a weak state. The seed soot a that moves along the movement path toward the discharge point Z moves while eliminating the bulky state by receiving the guiding action by the guide body 82 in a state where the pressing action by the guide body 82 gradually increases.

  The support 90 is made of a sheet metal member, and easily swings in the radial direction of the feeding rotary body 52 with a portion connected to the brush support portion 54b of the scraped body 54 as a swing fulcrum. The feeding guide 80 prevents the increase in the holding force of the seed pod a by the guide main body 82 and the feeding rotary body 52 even by the swinging deformation of the support 90, and weakens the friction between the seed potato a and the guide surface 81. Suppress.

As shown in FIG. 9 and FIG. 11B, the guide plate 84 is provided on both sides of the brush portion 54 a of the scraped body 54 in a state where the support plate 90 supports the guide plate 84. The guide plate 84 prevents the seed pod a that has entered between the brush hairs in the brush portion 54 a from entering between the brush bristles and the lateral wall plate portion 51 c of the feeding case 51.

  The downstream scraper 54 is supported by the feeding case 51 via a rotation support shaft 72 so as to be swingable. FIG. 8 shows a state where the scraped body 54 and the feeding guide 80 are operated to the open posture. As shown in this figure, the rotary support shaft 72 is rotated by an opening / closing lever 100 disposed outside the supply case 51 and attached to the end of the rotary support shaft 72, whereby the scraped body 54 and the supply guide are provided. 80 is switched to the open posture to form a discharge path 101 on the outer peripheral side of the feeding rotary body 52, and the seed potato a remaining in the powder tank 32 is discharged into the cylindrical body 56 through the discharge path 101. be able to.

As shown in FIGS. 5 and 6, the flow guide plate 57 is detachably attached to the inside of the feed case 51 by a connecting means 95 provided over the flow guide plate 57 and the feed case 51.
That is, when inspecting or exchanging the feeding rotary body 52 and the scraping body 53, the flow guide plate 57 is removed to secure a working space in the upper portion of the feeding case 51. In addition, when supplying powdered fertilizer or the like instead of the seed vat, the flow guide plate 57 and the scraped body 53 are removed, and a supply space for supplying the granular material to the feeding rotary body 52 is provided with the wall 51g. It is formed on the upper side of the feeding rotary body 52 by the downstream scraper 54. That is, when supplying fertilizer or the like in place of seed pods, the width of the supply space in this case in the rotation direction of the feeding rotator is larger than the width of the supply space 50 in the direction of rotation of the supply rotator in the case of supplying seed pods. Even if the specific gravity of the fertilizer is smaller than the specific gravity of the seed pod, the time for the feeding recess 58 to reach the supply space is lengthened so that the fertilizer etc. enters the feeding recess 58 with a predetermined set amount with high accuracy. When sowing seed supply is performed, the width of the supply space 50 in the rotating direction of the feeding rotary body is reduced by attaching the flow guide plate 57, and the load of the soot seed applied to the feeding rotary body 52 is suppressed to be small.

  The connecting means 95 includes a support body 96 provided with a rod installed inside the feeding case 51, and a connecting hook 97 integrally formed with the flow guide plate 57.

  The support body 96 provided in the feeding case 51 is disposed so as to be positioned above the flow-down guide plate 57 in a state of being attached to the inside of the feeding case 51 in a predetermined mounting posture.
