Buffering mechanism of this kind, although engaged so as to be easily attached and detached to the rubber net support member, conventionally, as shown in FIG. 9, the buffer hose 13 supporting the engaging ring 14 of the end members 18 Therefore, when the elastic shock absorbing hose 13 is dropped by the root vegetables, the reaction ring 14 causes the engagement ring 14 at the end of the U-shaped hook 19 of the support member to be attached. It was easy to come off from the free end, making it difficult to prevent root vegetables from colliding, and repairing them required time and effort.

Accordingly, a first object of the present invention is to provide a buffer hose engaging mechanism in which both end support portions of the buffer hose are not likely to come off from the hook-shaped engaging member, and the hose can be easily detached.

By the way, the buffer hose group of the storage tank, when it is desirable to deepen the slack of the hose sequentially from one side of the hose group to the other side, when it is desirable to set the depth gradually from both sides toward the center, There are various forms such as when uniform sagging is desired.
Japanese Utility Model Laid-Open No. 2-61944 discloses an embodiment in which both side support members for engaging a rubber net group are arranged in a V shape or an embodiment in which they are arranged in a flat shape. A separate support member must be prepared for each arrangement form, and the entire support members on both sides must be removed and replaced, which makes the operation remarkably complicated.

  Accordingly, a second object of the present invention is to provide the buffer hose engaging mechanism capable of variously changing the slack arrangement of the hose group simply by replacing common parts in the buffer hose group.

In order to achieve the first object, the basic configuration of the present invention is a locking mechanism for a group of fall buffer hoses installed in a storage tank of a root vegetable harvesting machine. A pair of supporting frames fixed relative to each other; a bending plate is integrally formed on an upper edge and / or a lower edge of a connecting plate attached to and detached from the supporting frame; and a plurality of supporting frames are formed along the longitudinal direction of the bending plate. A locking member main body configured to fix a base end portion of a J-shaped hook in parallel, and to detachably engage a tip locking ring of the drop buffer hose with a free end of the J-shaped hook; J, which is interposed between the engaging member main bodies and is fixed to the engaging member main body on the upper edge and / or the lower edge of the mating plate which is detachably connected to the back surface of the connecting plate of the engaging member main body. Glyph A retaining bracket integrally formed with a plurality of closing pieces that close or close to the free end corresponding to the free end and close the gap; and a relative of the connecting plate of the engaging member body and the mating plate of the retaining bracket a bolt passed through the through holes, characterized by removably coupled to the bolt engaging portion of the previous SL support frame.

In order to achieve the second object, the invention of claim 2 is characterized in that, in the mechanism, the engagement bottom portions of the plurality of J-shaped hooks fixed along the longitudinal direction of the folding plate of the engaging member body are bent. with projecting dimension of the tank inwardly toward the one longitudinal end to the other end side of the plate is set to be gradually increased, and correspondingly, the stopper fitting opposite the free end of J-shaped hooks The overhanging dimension of the tank of the plurality of closing pieces is gradually set wider from the one end side to the other end side of the retaining metal fitting.

  According to a third aspect of the present invention, the engagement bottoms of the plurality of J-shaped hooks fixed along the longitudinal direction of the folding plate of the engaging member body are tanks as they go from the left and right sides in the longitudinal direction of the folding plate toward the center. The inward projecting dimension is set so that it gradually becomes longer, and correspondingly, the projecting dimensions of the multiple closing pieces of the retaining bracket facing the free end of the J-shaped hook are set to the left and right sides of the retaining bracket. It is characterized in that the width gradually increases from the center toward the center.

  In the buffer hose engaging mechanism according to the present invention, the free ends of the individual J-shaped hooks fixed to the bent horizontal plate of the engaging member main body are closed by the corresponding closing pieces of the retaining metal fittings according to the above configuration. For this reason, the both-end engagement ring of the buffer hose engaged from the free end of the J-shaped hook does not have a possibility of coming off from the free end of the J-shaped hook even if the buffer hose is flipped up by the expansion and contraction reaction.

  Since the gap between the free end of the J-shaped hook and the retaining bracket closing piece is closed by tightening the bolt and opened by loosening the bolt, the buffer hose engagement ring can be easily attached and detached.

  By changing the position arrangement of the J-shaped hook engaging bottom that is fixed along the longitudinal direction of the folding plate of the engaging member main body, various arrangements of the slackness of the buffer hose group can be obtained such as slack slack, medium slack, and uniform slack. It can be set to form.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 illustrates members constituting a buffer hose engaging mechanism of a root vegetable storage tank according to the present invention and its assembly, and is integrally coupled to the opposing inner frame of the storage tank (not shown), or The support frame 1 constituting the inner frame itself, the engagement member main body 3 to which a plurality of J-shaped hooks 2a to 2n are fixed, the support frame 1, the engagement member main body 3, and the retaining metal fitting 4 are combined to provide the support. Bolts 5 that are attached to and detached from the frame 1 are provided.

Notches 12a to 12n are formed corresponding to the respective J-shaped hooks 2a to 2n so as to form a predetermined gap facing to 11n, and the engaging ring 14 at the end of each buffer hose 13 is formed. The free ends 11a to 11n corresponding to the J-shaped hooks 2a to 2n are fitted and engaged through the gaps of the notches 12a to 12n.

The retaining metal fitting 4 is externally fitted to the engaging member main body 3 from behind, and has an alignment plate 15 having a predetermined vertical width facing the back surface of the connecting plate 8 of the engaging member main body 3. Free ends 11a to 11n on the upper edge and lower edge of the plate 15 near the free ends 11a to 11n of the J-shaped hooks 2a to 2n fixed to the bending plates 9 and 10 of the engaging member main body 3, Closing pieces 16a to 16n for closing gaps between the notches 12a to 12n are integrally formed.
A through-hole 17 of a bolt 5 corresponding to the through-hole 7 drilled in the connecting plate 8 of the engaging member main body 3 projects from the mating plate 15 of the retaining metal fitting 4.

Thus, the retaining metal fittings 4 are opposed to each other from the back surface of the engaging member main body 3, and the bolts 5 are inserted into the corresponding through holes 7, 17, and the bolts 5 are inserted into the support portions 6 of the support frame 1. Screw the tip of the screw with temporary fixing.
In the assembly process of the screwing screwing, the engaging member main body 3 and the retaining metal fitting 4 are loosely fitted to the shaft of the bolt 5 so that the J-shaped hooks 2a to 2n of the engaging member main body 3 are fitted. Since the gap is held between the free ends 11a to 11n of the metal fittings 4 and the closing pieces 16a to 16n of the retaining metal fitting 4, the engaging ring 14 of the buffer hose 13 is fitted from the free ends 11a to 11n of the J-shaped hooks 2a to 2n. And are engaged with the J-shaped hooks 2a to 2n.

Thereafter, when the bolt 5 in the temporarily fixed state is fastened to the support portion 6 of the support frame 1, the engaging member main body 3 and the retaining metal fitting 4 are closely coupled to the support frame 1 as shown in FIG. 2. As a result, the engaging member main body 3 and the notches 12a to 12n are closed by the closing pieces 16a to 16n of the retaining metal fitting 4, and there is no gap on the tip side of the J-shaped hooks 2a to 2n.
Thus, as shown in FIG. 3, even if the buffer hose 13 springs up due to the spring reaction, the engagement ring 14 at the tip is interfered with the closing pieces 16a to 16n of the retaining bracket 4, and the free ends 11a of the J-shaped hooks 2a to 2n. It does not deviate from ~ 11n.
Further, when the bolt 5 is loosened, a gap is generated at the front end side of the free ends 11a to 11n of the J-shaped hooks 2a to 2n, and the buffer hose 13 can be detached.

  In the illustrated embodiment, J-shaped hooks 2a to 2n and notches 12a to 12n are provided on upper and lower folding plates 9 and 10 on both upper and lower edges of the engaging member main body 3 in two upper and lower stages through a predetermined vertical width. Correspondingly, closure pieces 16a to 16n are provided in two upper and lower stages on both the upper edge and the lower edge of the retainer metal fitting 4, so that the net comprising the buffer hose 13 group is constructed in two stages. Although illustrated, this invention is not limited to this, The case where it is set as a 1 step | paragraph structure is also included.

  In addition, when the J-shaped hooks 2a to 2n of the engaging member main body 3 and the notches 12a to 12n and the closing pieces 16a to 16n of the retaining metal fitting 4 are formed in two stages, the hook on one stage is the other stage. The upper and lower two-stage buffer hoses 13 arranged between adjacent hooks are stretched up and down in a zigzag manner.

  FIGS. 1 to 3 show only one side engaging portion of the buffer hose engaging mechanism. However, when installing in the tank, as shown in FIG. A similar mechanism is provided, and the both end engaging rings 14 of the buffer hose 13 group are engaged and installed in a net shape.

  1 and 2, the engagement bottom portion of the J-shaped hooks 2 a to 2 n of the engagement member body 3, that is, the engagement portion of the engagement ring 14 of the buffer hose 13 is on one side of the support frame 1. The length of the inward extension of the tank becomes longer as it goes from the other side to the other side, and correspondingly, the closing piece of the retaining metal fitting 4 facing the free ends 11a to 11n of the J-shaped hooks 2a to 2n The overhanging dimensions of the tanks 16a to 16n are set longer from one side of the retaining metal fitting 4 to the other side. In the embodiment configured as described above, as shown in FIG. 5 and FIG. 6, the slack depth of the buffer hose 13 group is inclined to one side in the tank, and the root vegetables permeated into the tank are transferred to the buffer hose 13 group. Pass while rolling along the slope.

  On the other hand, the arrangement of the sag depth of the buffer hose 13 group according to the present invention is not limited to this, and for example, as shown in FIG. 7, the engagement bottoms of the J-shaped hooks 2a to 2n of the engagement member body 3 are engaged. The extension dimension toward the inside of the tank is set longer from the both sides of the member main body 3 toward the center, and the figure is omitted, but the extension extension dimensions of the closing pieces 16a to 16n of the retaining metal fitting 4 are correspondingly increased from both sides. You may make it the structure set long as it goes to the center. In this embodiment, as shown in FIG. 8, the installed buffer hose 13 group becomes deeper from both sides toward the center, and the root vegetables introduced are directed from both sides to the center part of the buffer hose 13 group. Passes downward while rolling.

  FIGS. 5 to 8 show a state before the retaining metal fitting 4 is attached to the engaging member body 3 for easy understanding of the description.

Since the buffer hose that interferes with the falling speed of the root vegetables does not come off due to the recoil due to the expansion and contraction, the yield due to the damage of the root vegetables is improved, and the productivity is improved.
Moreover, since the work interruption due to the removal of the buffer hose is eliminated, the harvesting work efficiency is improved.
