Description

  The present invention relates to a trimming body and a glaze coating machine equipped with a trimming body, and in particular, includes a slope trimming unit that trims the slope of a kite and an upper surface trimming unit that shapes the upper surface of the kite. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trimming body having a plurality of blades attached to a collar and a tack coater including the trimming body.

  Traditionally, in the lacquering machine that shapes the cocoon, the pre-processing part that cuts the old cocoon (former cocoon) and fills the earth, and the soil piled up by this pre-processing part is rotated and compacted to shape the new cocoon The one provided with the trimming body is generally used.

  Further, as such a trimming body, a frustoconical slope trimming part that shapes the slope of the collar, and a cylindrical member that is connected to the top side of the slope trimming part and shapes the upper surface of the collar What is provided is widely known.

  In recent years, a technique for arranging a plurality of blades having flexible elasticity at a predetermined interval in the circumferential direction has been known as such a coater.

  According to such a technique, when the trimming body rotates, after the upper surface of the collar is gradually tightened by a portion (elastic deformation of the blade plate) that is not fixed to the tubular member of the blade plate, Because it is strongly squeezed by the part fixed to the cylindrical member of the paddy, it will shape a robust new paddy with a better finish regardless of the soil conditions of the field (for example, wet fields with high water content or dry fields with low water content) It becomes possible.

  Here, in general, the vane plate is formed of a relatively weak member such as a synthetic resin (for example, nylon resin or vinyl chloride resin) or a steel plate (for example, a spring steel plate). Over time, wear often causes damage. In such a case, it is necessary to replace the damaged blade plate with a new blade plate. However, such replacement is troublesome and labor-intensive, and the work is complicated.

  Therefore, for example, it is possible to pass through each of the cylindrical member in which the elongated hole-shaped insertion hole is formed, the blade plate in which the insertion hole is formed, and the insertion hole of the cylindrical member and the insertion hole of the blade plate. A plastering machine has been proposed that includes an attachment member formed with an engagement portion and a bolt for fixing the attachment member to a stiffening plate attached to a cylindrical member (see Patent Document 1).

  In such a coater, the blades are attached to the tubular member by first inserting the engaging portions of the attachment members into the tubular member insertion hole and the blade plate insertion hole, respectively. In order to engage the insertion hole with the engaging portion, the mounting member is moved toward the slope adjusting portion side, and then to the side opposite to the slope adjusting portion side (hereinafter referred to as “shaft tip direction”). In order to restrict the movement of the blades, the mounting member is fixed to the cylindrical member (stiffening plate) by bolting.

  In addition to the plastering machine described in Patent Document 1, for example, a base member in which a long hole-like base side hole is formed (hereinafter referred to as a “tubular member”), and a long hole-like plate side hole.畦 upper surface forming plate (hereinafter referred to as “blade plate”) formed with, a holding member formed with an engaging portion that can be inserted into each of the base side hole and the plate side hole, and 畦 upper surface formation A plastering machine has also been proposed that includes a stopper member for restricting the movement of the plate and the clamping member in the axial direction and a stopper mounting bolt for fixing the stopper member to the cylindrical member (see Patent Document 2).

  In such a coater, the blade plate is attached to the cylindrical member by first inserting the engaging portion of the clamping member into each of the base side hole of the cylindrical member and the plate side hole of the blade plate. In order to engage the base side hole and the plate side hole with the engaging portion, the clamping member is moved toward the side surface forming body (slope surface forming portion) side, and then the cylinder on the side opposite to the side surface forming body side In order to restrict the movement of the cylindrical member and the blade, the stopper member is fixed to the cylindrical member by bolting.

  According to the plastering machine described in Patent Document 1 and Patent Document 2, it is possible to easily attach the slats (the upper surface forming body) to the cylindrical member (base member) to some extent.

However, as described above, in each of the coating machines described in Patent Document 1 and Patent Document 2, the engaging portions formed on the attachment member (Patent Document 1) and the clamping member (Patent Document 2) are used as the blades. In addition to being inserted through the holes formed in each of the plate and the cylindrical member and engaging the mounting member (Patent Document 1) and the stopper member (Patent Document 2) to the cylindrical member for the first time, The movement of the blade plate relative to the tubular member is restricted (the blade plate is fixed to the tubular member).
That is, it can be said that the wrinkle coater described in Patent Document 1 and Patent Document 2 has a relatively complicated structure for fixing the blade plate to the tubular member.

  Here, in the technical field of joining members together, it is common that the mounting strength (fixing strength) of the members improves as the structure becomes complicated.

  However, in the wrinkle coater described in Patent Document 1 and Patent Document 2, as described above, the head is directed toward the shaft tip with respect to the blade plate during the trimming operation, despite the relatively complicated structure. When force is applied, stress tends to concentrate on the bolt that fixes the mounting member (Patent Document 1) and the stopper member (Patent Document 2), and in some cases, the mounting member and the stopper member are detached from the cylindrical member. There was a fear. In such a case, in the coater described in Patent Document 1 and Patent Document 2, since no measures other than the above bolts are provided to restrict the movement of the blade plate in the axial tip direction, the blade plate is very simple. There arises a problem that the tubular member comes off.

  Moreover, after the temporary coating of the vane plate to the cylindrical member by the attachment member (Patent Document 1) and the clamping member (Patent Document 2), both the coating machines described in Patent Document 1 and Patent Document 2, In order to fix these attachment members and clamping members to the cylindrical member, it is configured to be bolted using a jig such as a wrench.

  For this reason, in the surface coating machine described in Patent Literature 1 and Patent Literature 2, there is a problem that the blade plate is not sufficient in terms of simple replacement of the blades.

  In addition, in the wrinkle coater described in Patent Document 1 and Patent Document 2, it is necessary to prepare a separate member such as a bolt or a mounting member in addition to the blade plate and the cylindrical member, which increases the number of parts (increasing cost). There was also a problem.

  The present invention has been made to solve the above inconveniences, and an object of the present invention is to regulate the movement of the blade plate in the axial tip direction with respect to the tubular member without complicating the structure. An object of the present invention is to provide a trimming body and a tack coater provided with the trimming body.

  In addition, another object of the present invention is to provide a trimming body and a trimming body for use in a plastering machine and the like that can more easily perform blade blade replacement work without increasing the number of parts and complicating the structure. There is also the provision of a coater with a casing.

  The problem is that, according to the trimming body according to the present invention, the slope trimming section capable of shaping the slope of the collar by rotation around the shaft, and the shaft tip direction side of the slope trimming section. An upper surface trimming unit that is connected and rotates together with the slope trimming unit to shape the upper surface of the collar, and the upper surface trimming unit is formed in a cylindrical shape. A cylindrical member and a plurality of blades attached to the outer peripheral surface of the cylindrical member, the blades being capable of engaging with an engaged portion formed on the cylindrical member. This is solved by restricting the movement of at least the cylindrical member in the direction of the shaft tip by having a joining portion and engaging the engaging portion with the engaged portion.

  Moreover, the said subject is solved by providing the said trimming body according to the coating machine which concerns on this invention.

  In the above configuration, by engaging the engaging portion of the blade plate and the engaged portion of the tubular member, at least movement of the blade plate toward the axial front end side with respect to the tubular member is regulated. ing. For this reason, even if it is a simple structure, even if the force which goes to an axial front-end | tip direction acts with respect to a vane plate during the trimming operation by a vane plate, a vane plate will remove | deviate from a cylindrical member carelessly. This can be sufficiently suppressed.

  Moreover, in the said structure, in the state which made the engaging part and the to-be-engaged part engaged, not only the movement to the axial front-end | tip direction of the blade blade with respect to a cylindrical member is controlled, but the circumferential direction of a cylindrical member If the movement in the radial direction is also restricted (Claims 2 to 4), then the direction opposite to the axial direction of the blade plate relative to the tubular member (hereinafter referred to as "anti-axial distal direction"). If a measure is taken to restrict the movement to the side), the blades can be fixed to the tubular member.

  As such a treatment, for example, the second engagement that restricts the movement of the tubular member in the direction opposite to the distal end with respect to the tubular member while being engaged with the second engaged portion formed on the tubular member on the blade plate. It is conceivable that an additional portion is provided (claims 5 and 6).

  When comprised in this way, if a engaging part and a 2nd engaging part are engaged with a to-be-engaged part and a 2nd to-be-engaged part, respectively, a blade can be fixed to a cylindrical member. On the other hand, the blade plate is removed from the tubular member by releasing the engagement state of the engagement portion and the engaged portion and the engagement state of the second engagement portion and the second engagement portion, respectively. It is possible.

  That is, in such a configuration, a simple configuration in which an engaging portion and a second engaging portion, an engaged portion and a second engaging portion are provided on each of the blade plate and the cylindrical member, It is possible to exchange the blades very easily. Moreover, in the said structure, when fixing a blade | wing plate with respect to a cylindrical member, since components other than these blade | wing plates and a cylindrical member are not used, reduction of a number of parts can be aimed at.

  In addition, when the tubular member to which the vane plate is attached is fixed to the slope trimming body, if the vane plate is configured to contact the slope trimming body, the existing one (the slope trimming body) ) Can be used to regulate the movement of the slats toward the opposite end of the shaft (claim 7).

  In such a case, if the second engaging portion and the second engaged portion described above are damaged or deformed, the anti-axial tip direction side by the second engaging portion and the second engaged portion is assumed. Even if the function of restricting the movement of the blade is reduced, it is possible to restrict the movement of the blade in the anti-axial tip direction.

  If the treatment for restricting the movement of the blade plate in the direction opposite to the distal end of the blade is performed, the blade blade replacement operation can be performed very simply without using a jig such as a wrench. In addition, when fixing the blades to the cylindrical member, it is possible to configure so as not to use components other than the blade plate and the cylindrical member. In such a case, it is possible to reduce the number of components. is there.

Thus, according to the trimming body or the wrinkle coater according to the present invention, the movement of the blade plate in the axial tip direction relative to the tubular member can be restricted with a simple configuration.
In addition, according to the trimming body or the wrinkle coater according to the present invention, it is possible to more easily replace the blades without increasing the number of parts and complicating the structure.

The axially extending portion 67 comes into contact with the slope forming plate 45 in a state where the cylindrical member 51, the blade plate 61, and the slope adjusting portion 41 are assembled (see FIG. 2).

  Next, a method for fixing the blade 61 to the tubular member 51 will be described with reference to FIGS.

  As shown in FIGS. 3 and 4, the blade plate 61 is fixed to the tubular member 51 first by bending each of the bent pieces 63 b and 63 b of the first claw portions 63 and 63 formed on the blade plate 61. It starts by inserting through the first holes 53 and 53 of the tubular member 51.

  Specifically, in a state where the first claw portions 63 and 63 are positioned on the axial tip direction side of the first hole portions 53 and 53, the standing piece portions 63a and 63a of the first claw portions 63 and 63 are The first claw portions 63 and 63 are inserted into the first hole portions 53 and 53 until they contact the opening edge portions of the portions 53 and 53.

  Next, with the first hole portions 53 and 53 and the first claw portions 63 and 63 as the rotation center, the rotation direction extending portion 66 side (counter rotation direction side) of the blade plate 61 is rotated toward the tubular member 51. The second claw portions 64 and 64 are inserted into the second hole portions 54 and 54, respectively.

  Then, after inserting each of the 2nd nail | claw parts 64 and 64 in the 2nd hole parts 54 and 54, the blade board 61 is slid and moved toward the axial front-end | tip direction. In this way, when the blade 61 is slid, the second claw portions 64 and 64 gradually sandwich the flat portion 52b adjacent to the opening edge of the second hole portions 54 and 54, and The lock part 65 moves on the lock hole part 55 in contact with the part adjacent to the opening edge part of the lock hole part 55 in the flat part 52b. At this time, the axially extending portion 67 side of the blade 61 is slightly elastically deformed toward the radially outer side of the tubular member 51.

  Then, when the blade 61 is further slid in the axial tip direction and reaches the position where the lock portion 65 is aligned with the lock hole 55, the elastically deformed blade plate 61 is restored (the shaft of the blade 61). The locking portion 65 penetrates and engages with the locking hole portion 55 by the deformation of the direction extending portion 67 side toward the radially inner side of the tubular member 51.

  As a result, the blade 61 is fixed to the cylindrical member 51.

  As shown in FIG. 5, in the state where the blade 61 is fixed to the cylindrical member 51, the axial tip end side of the first claw portions 63 and 63 is the opening on the axial tip end side of the first hole portions 53 and 53, respectively. The side surfaces of the second claw portions 64 and 64 on the axial tip direction side are arranged in contact with or close to the edge portions, and the side surfaces on the axial tip direction side of the second hole portions 54 and 54, respectively. It arrange | positions in contact with or adjoins to the opening edge part of the side.

  For this reason, in the present embodiment, the movement of the vane plate 61 in the axial tip direction with respect to the tubular member 51 is mainly caused by the rising edge of the first hole portion 53 on the axial tip direction side and the rising of the first claw portion 63. Abutting with the side surface on the axial tip end side of the piece portion 63a, an opening edge portion on the axial tip direction side of the second hole portion 54, and a side surface on the axial tip end side of the standing piece portion 64a of the second claw portion 64 It is regulated by the abutment.

  Further, in the present embodiment, in the state where the blade plate 61 is fixed to the tubular member 51, the end of the blade plate 61 (tubular member mounting portion 62) on the axial tip end side is the plate portion 56 of the tubular member 51. It arrange | positions in the position which adjoined (or contact | abutted) the edge part 56a.

  For this reason, in this embodiment. For example, the axial tip direction side of the upright piece portion 63a of the first claw portion 63 and the axial tip direction side of the upright piece portion 64a of the second claw portion 64 are worn away by wear, so that the first claw portion 63 and the second claw portion 64 are worn. Even when the function of restricting the movement of the blade 61 in the axial tip direction due to the drop is caused, the end on the axial tip direction side of the blade 61 comes into contact with the end 56 a of the plate portion 56.
