In the powder and grain feeding device, particularly required performances are “accuracy of feeding amount” and “secure of the shape of the fed material, that is, no cracks, crushing, and peeling of the coating material”. Further, depending on the work, “intermittent feeding accuracy” is also required.
However, the `` feeding accuracy '', which is the accuracy of whether the feeding amount is constant, the `` point seeding accuracy '', which is the accuracy of feeding the feeding material intermittently at a certain distance, and the initial shape of the feeding material Although “shape securing accuracy” that does not hurt or deform is required, these accuracy are conflicting items that are likely to affect the other if too much is determined.
In order to improve the “point seeding accuracy”, a method of holding a fed product by a guide until immediately before being discharged from a roll is often used. However, since the fed material continues to be sandwiched between the roll groove and the guide for a long distance and time, the fed material is broken when the feeding amount is large, and when the coating material is covered, the coating material is Many peels occur.

In order to improve the accuracy of the number of particles of the delivered material, which is the “delivery accuracy”, a method of scraping the delivered material overflowing from the roll groove portion with a brush or the like is used.
In this case as well, rubbing off the overflowing part will cause cracking or peeling of the ejected material, and wear will also occur on the brush on the scraping side. It becomes.
In addition, there are various objects to be fed out in the material to be fed, and their particle diameters are different. Since the feeding amount differs depending on the situation, the opening degree, which is the size of the roll groove, needs to be changeable. However, when the number of lines is large, it takes time and labor to adjust the feeding amount. .
In the slide roll type feeding device, "feeding accuracy" which is the accuracy of whether or not the feeding amount is constant, "dot seeding accuracy" which is the accuracy of feeding the feeding material intermittently with a certain distance, and the feeding material "Shape securing accuracy" that does not hurt or deform the initial shape of the is required, but these accuracy are conflicting items that are likely to affect the other if too much is determined.
According to the present invention, a structure for improving the accuracy of each of the above is configured by disposing an inlet capsule inside the feeder case, and a shielding guide plate, a shutter plate, and a restriction guide protrusion are attached to the inlet capsule. Things.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

In Claim 1, a slide for disposing a non-sliding side feeding roll and a sliding side feeding roll inside a feeding part case, and placing and fixing a hopper storing powdery particles at an entrance of the feeding part case. In the roll-type feeding device, an inlet-side opening communicating with the hopper is opened in the feeding-portion case, and inside the entrance-side opening , powder particles that are detachable from the feeding-portion case flow. An inlet capsule as an entrance is fitted, and an arc-shaped partition guide plate fitted into a partition groove formed in the outer periphery of the non-sliding side feeding roll is integrally fixed to the inlet capsule. It is a thing.

According to a second aspect of the present invention, in the slide roll type feeding apparatus according to the first aspect, the inlet capsule is directed toward a restricted entrance formed by a partition groove and a partition guide plate formed outside the non-sliding side feed roll. In addition, a restricting guide projection for guiding the granular material is integrally provided.

According to a third aspect of the present invention, in the slide roll type feeding device according to the first aspect, a shutter plate for adjusting an amount of flow into the feeding portion is attached to the entrance capsule so as to be integrally adjustable.

  The present invention has the following effects.

  With this configuration, it is not necessary to mount the restriction guide projection, the shielding guide plate, the shutter plate, and the like in a narrow place at the entrance of the lower part of the hopper in the feeding part case. After assembling them into the inlet capsule in a semi-mechanized state, they can be inserted into the feeding part case and assembled.

In addition, since the shield guide plate, which is difficult to install in a narrow position, can be attached to the entrance capsule outside the feeder case to form a semi-structure, assembly and maintenance can be facilitated.

According to the second aspect of the present invention, the restricting guide projection for restricting the width of the material to be fed into the roll of the slide roll type feeding device can be formed integrally with the inlet capsule. In addition, it is possible to provide a restricting guide projection which is easy to manufacture and has a good slide-out of the ejected material.

Since it is configured as in claim 3, since Ru mounting the shutter plate to the inlet portion capsule, in a state where taken out inlet portion capsule 1, than it has been possible to attach and adjusted the shutter plate at a high precision state .

In addition, with such a structure, it is a versatile feeding part with "accuracy of feeding amount", "securing of the shape of the feeding material", "adjustment of the strip width", "adjustment of all the opening of the strip" and "stoppable" It is.
In addition, by holding the delivered material to the discharge point by the outer peripheral guide behind the brush, the delivered material can be released to the field in one lump. This leads to an improvement in spot seeding accuracy.
The outer periphery guide is not fixed, but is made swingable, so that breakage of the ejected material and peeling of the coating material caused by friction can be reduced.

  In the powder and granular material feeding device, particularly required performances are “delivery accuracy”, “pointing accuracy”, and “shape ensuring accuracy”. That is, the `` feeding accuracy '' which is the accuracy of whether the feeding amount is constant, the `` point seeding accuracy '' which is the accuracy of feeding the feeding material intermittently at a fixed distance, and the initial shape of the feeding material "Shape ensuring accuracy" that does not hurt or deform is required, but these accuracy are conflicting items that are likely to affect the other if too much is determined.

  In order to improve the “point seeding accuracy”, a method of holding a fed product by a guide until immediately before being discharged from a roll is often used. However, since the fed material continues to be sandwiched between the roll groove and the guide for a long distance and a long time, the fed material is broken when the feeding amount is large, and when the coating material is covered, Many peels occur.

  In order to improve the accuracy of the number of particles of the delivered material, which is the “delivery accuracy”, a method of scraping the delivered material overflowing from the roll groove portion with a brush or the like is used. In this case as well, scraping off the overflowing part will cause breakage and peeling of the ejected material, and wear will also occur on the brush on the scraping side, so labor and cost for replacing parts etc. are required It becomes. In addition, there are various objects to be fed out in the material to be fed, and their particle diameters are different. Since the feeding amount differs depending on the situation, the opening degree, which is the size of the roll groove, needs to be changeable. However, when the number of strips increases, time and labor are required to adjust the feeding amount. .

  For this reason, a roll-type seeder equipped with a mechanism for adjusting the opening of all the strips at once is also known, but since there are individual differences due to component precision, mechanisms that can be adjusted individually are also required. is necessary. In addition, since the spacing between seeds varies depending on the material to be fed, it is necessary to provide a "strain adjusting mechanism" that allows the entire feeding portion to be movable. In addition, although a technique using a full-row opening adjustment mechanism and a locking mechanism is disclosed for a dedicated machine such as direct sowing of paddy rice paddy, it is impossible to adjust the spacing between the rows. It was.

The engaging claw 6a is pressed to maintain the engaged state. An engagement / disengagement claw 7a is configured to maintain the engaged state of the locking clutch 6, and when the operation knob 7b is operated to the engagement side, the engagement / disengagement claw 7a presses the clutch urging spring 6c. And the locking clutch 6 is prevented from coming off. When the operation knob 7b is operated to the release side, the engagement / disengagement pawl 7a pushes the sliding-side engaging pawl 6b so that the locking clutch 6 can be disengaged, and the power of the slidable support shaft is transmitted to the feeding drive shaft 5. Is configured not to be.

  The feed drive shaft 5 supporting the stop clutch 6 and the stop clutch operating portion 7 is inserted from the side into a perforated hole opened on the side surface of the feed portion case 2, and the feed drive shaft 5 is connected to the feed portion. The locking clutch 6 is disposed at a portion disposed at the upper opening of the case 2. Since the portion of the locking clutch operating portion 7 is formed on the feeding drive shaft 5 protruding from the right side surface of the feeding portion case 2, a hopper or the like is placed above the feeding drive shaft 5 in a supported state. Even after being fixed, the locking clutch operating section 7 can be operated from the outside of the feeding section case 2.

  On the right side surface of the feeding portion case 2, a feeding amount adjusting portion 4 is formed. The feed amount adjusting section 4 includes a feed amount adjusting gear 15 screwed to a screw shaft 17 and a feed amount adjusting drive gear 16. The feed amount adjustment unit 4 has been described above.

  As shown in FIGS. 1 and 2, on the side surface of the feeding portion case 2, a connection driving shaft of a feeding amount adjusting drive gear 16 for driving the feeding amount adjusting portion 4 is provided below the feeding drive shaft 5. An opening is also provided in which 14 is supported. In FIG. 2, the connection drive shaft 14 has a hexagonal hole opened therein, and a feed amount adjustment drive shaft 21 fitted in common between a plurality of left and right slide roll type feed devices is provided inside the connection drive shaft 14. It is inserted to allow a plurality of feed amount adjustment sections 4 to be adjusted simultaneously, and the connection drive shaft 14 of the feed amount adjustment drive gear 16 slides left and right on the feed amount adjustment drive shaft 21 to adjust the gap between the strips. It is configured to allow the slide roll type feeding device to move left and right.

  Next, the feeding mechanism will be described with reference to FIGS. In the slide roll type feeding device, the feeding mechanism of the slide roll type feeding device is of a pumping type, so that the feeding material which cannot be entered into the groove falls by its own weight, so that a large amount of the feeding material does not needlessly enter the groove. It is composed. When the material to be fed up to the upper part of the roll, the brush is present, so that the material to be fed more than the groove is scraped off. Thereby, the accuracy of the number of grains is improved. Since a large amount is not put into the groove by the pumping method, the amount rubbed by the upper brush is reduced, and cracking of the ejected material and peeling of the coating material are reduced. In addition, it is possible to suppress abrasion of the brush.

  Next, after the unreeling material is positioned above the roll, the shielding plate disappears, and the groove width increases. As a result, the unreeling material that fits into the groove moves toward the expanded space, so that there is room in the groove. When passing through the portion of the outer peripheral guide 26 behind the brush, a margin is provided between the outer peripheral guide 26 and the outer peripheral guide 26, which leads to reduction of cracking and coating peeling. In addition, since the delivery material is arranged in the direction perpendicular to the traveling direction, the landing shape on the field, that is, the length in the traveling direction is shorter than usual, and the outer periphery guide 26 that can improve the spot seeding accuracy is located at the upper side. , And can be pivoted downward to the pivoting side.

  By holding the delivered material to the discharge point by the outer peripheral guide 26 behind the brush, the delivered material can be released to the field in one lump. It leads to improvement of spot seeding accuracy. The guide is not fixed, but can be swung, so that breakage of the feeding material and peeling of the coating material caused by friction can be reduced. The adjustment of the slide roll is made up of a combination of gears, and the drive gear for adjustment can be arranged at a position shifted from the rotation axis of the roll. It becomes possible.

  By rotating this shaft, it is possible to adjust multiple openings at a time. Further, since the drive shaft and the feeding portion are not fixed, the feeding portion can be moved. As described above, it is possible to configure a feeding portion that satisfies “improvement of spot seeding accuracy”, “improvement of grain number accuracy”, and “reduction of cracks and separation”. Further, it is possible to provide a slide roll type feeding device which can move between the strips and has a full-opening degree adjusting mechanism and a locking mechanism.

  The problem is solved by a roll having the following structure. Normally, a shielding plate fitting groove 9b of the shielding guide plate 18 is provided in the middle of the roll groove portion 9a of the non-sliding side feeding roll 9, which has been in communication with one. When the non-sliding side feeding roll 9 is rotated in a state where is fitted, the capacity of the feeding portion in the portion of the inlet capsule 1 is limited. The fixed-side feeding roll 9 is provided with a drive shaft hole 9c into which the roll drive shaft 8 is fitted in an engaged state. That is, the roll groove portion 9a is separated by the shielding plate fitting groove 9b, and the shielding guide plate 18 is fitted into the gap. However, the shielding guide plate 18 is arranged only about half of the rear side with respect to the roll rotation direction, and does not extend to other portions. In the roll groove 9a in the range where the shield plate exists, half of the entire groove width is regulated by the shield guide plate 18, so that it is impossible to move the supplied material.

  A roll brush 25 is disposed above the roll above the portion where the rolled-out material is inserted, where the roll groove 9a of the non-sliding-side roll 9 and the projection 10a of the sliding-side roll 10 are engaged with each other. . The roll brush 25 is not fixed, is urged by a spring from above, and has a structure capable of moving up and down. Further, since the shielding guide plate 18 does not exist forward of the roll brush 25 in the roll rotation direction, the shielding guide plate 18 is lost in the shielding plate fitting groove 9b, and the left and right roll groove portions are widened. In 9a, the delivery can be spread. That is, the roll groove 9a can be widened immediately before reaching the lower end of the roll guide width and the shield guide plate 18, that is, the restriction guide protrusion 20.

  Immediately behind the brush, an outer peripheral guide 26 made of iron or resin, sponge, new light seal, or the like is provided along the roll. The outer groove guide 9a of the non-sliding side feeding roll 9 and the projection of the sliding side feeding roll 10 are formed. The portion 10a is arranged on the outer periphery of the meshing portion. The feeding position of the feed from the hopper arranged above the inlet capsule 1 is not above the non-sliding side feeding roll 9 but the rotating outer periphery of the non-sliding side feeding roll 9 and the sliding side feeding roll 10. From the side or the oblique position of the roll groove 9a. Then, in the pumping state, the amount of unreeled material is set so that a certain amount or more does not enter the stagnation space 27 formed at the end of the shielding guide plate 18 and at the position before reaching the start end of the roll brush 25. The shutter plate 19 is attached to the inlet capsule 1 by a fastener 19a.

  The structure of the inlet capsule 1 is such that the inlet capsule 1 can be fitted in the space between the feeder case 2 and the upper hopper. The entrance capsule 1 has a portion to which the above-mentioned shutter plate 19 can be attached and a portion to which a shielding guide plate 18 to be fitted in a shielding plate fitting groove 9b formed in the non-sliding side feeding roll 9 is attached. By the shielding guide plate 18, the discharged material passes through the inside of the inlet capsule 1 from the hopper, passes under the shutter plate 19, and enters the retaining space 27, and is discharged from the inside of the left inlet capsule 1. A restricting guide projection 20 for guiding movement to a central position is provided from the side surface.

  The restriction guide projection 20 is formed integrally with the inlet capsule 1. Further, the inlet capsule 1 is provided with a fastening diagram in which the shielding guide plate 18 and the shutter plate 19 can be fixed by fasteners such as bolts as described above. When the plate 18 or the shutter plate 19 is attached, or when the restriction guide projection 20 is integrally formed with the extension case 2, it can be fitted inside the extension case 2 in order to facilitate assembly and maintenance. They are configured separately.

  In the space between the feeder case 2 and the hopper, there is provided a capsule fixing body 3 for preventing the entrance capsule 1 from coming out from above with the entrance capsule 1 fitted. The lower portion of the hopper is fixed to the capsule fixing body 3.

  FIGS. 14 to 18 disclose the overall configuration of the inlet capsule 1 constituting a main part of the present invention. That is, when viewed as a whole, the inlet capsule 1 has a shape in which the upper part of the rectangular parallelepiped is opened, and the inlet is dropped into the space closed by the capsule fixing body 3 at the upper part of the feeder case 2. It is configured to be closed and fixed by the capsule fixing body 3. The outer shape of the inlet capsule 1 and the inner diameter of the feeding portion case 2 are formed in a rectangular shape in a plan view so as to be fitted so as to prevent rattling. Just by inserting the inlet capsule 1 inside the feeder case 2, the restriction guide protrusion 20, the shielding guide plate 18, and the shutter plate 19 provided on the inlet capsule 1 have a predetermined distance and interval. It is fixed in a state.

  The entrance capsule 1 is provided with a shield plate mounting portion 30 for fixing the shield guide plate 18 with a fastener 18a. The shielding plate mounting portion 30 is formed at a position where the bottom surface 38 of the inlet capsule 1 and the outer periphery of the feeding rolls 9 and 10 meet near the approximate center of the left-right width of the inlet capsule 1. It extends to the position in front. The shielding guide plate 18 is formed as an arc-shaped long plate, has a shape along the outer periphery of the feeding rolls 9 and 10 and has a thickness to be fitted into the shielding plate fitting groove 9b in all orders.

  Further, the shield plate mounting portion 30 is provided to protrude forward from the shutter plate mounting portion 29 for mounting the shutter plate 19. The shutter plate mounting portion 29 is provided before the starting end of the shielding guide plate 18 and in front of the stay space 27 described above. In other words, they are erected in a direction perpendicular to the rotation direction of the feed rolls 9 and 10 to prevent the feed material from flowing into the stay space 27. On the front surface of the shutter plate mounting portion 29, a base of the shielding plate mounting portion 30 is fixed, and the shielding plate mounting portion 30 protrudes forward, and a shielding guide plate 18 is provided below the shielding plate mounting portion 30. It is fixed by the fastener 18a.
