Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a device for trimming the lower roots and stalks of rush seedlings prior to transplantation.

[0002]

[Prior Art]

 As a prior art of this kind of device, in Japanese Patent Laid-Open No. 3-108403, a pair of upper and lower endless conveyor belts sandwiches a stalk portion of a rush seedling and conveys it in a direction intersecting with the stem axis line thereof. There is disclosed an aligning device for locust seedlings, which is configured to cut the lower root portion and the tip portion of the rush seedling by two cutting means composed of a pair of disc cutters.

In this prior art, the worker hay and grass seedlings are mounted on the guide portions of the pair of front and rear inverted L-shaped markers provided on the supply port side of the pair of upper and lower endless conveyor belts and extending substantially horizontally in the conveying direction. The stalks on the tips of the stalks are placed by hand, and the roots and the cuts on the ears of the weed seedlings are applied to the endless conveyor belt while applying them so that they are located in the guides.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned prior art, when the roots of a plurality of or more than one strain of rush seeds disagree with each other in the stem axis direction, the roots should be abutted against the ground or the floor in advance in order to align the places where the lower roots are cut. After aligning the positions of the roots in the stem axis direction, the roots must be placed on the guides, and the location of the alignment work is different. There was a problem of getting dirty.

Further, since the guide portion extending in a substantially horizontal shape is disposed substantially at a position overlapping with the starting end portion of the lower endless conveyor belt, when the rush seedlings are placed on the guide portion, the conveying action is immediately performed. Therefore, there was also a problem that it was difficult to place saplings exactly on the guide part as a mark of the cutting point. In view of these circumstances, the present invention aims to provide a trimming device that is easy to work.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a pair of upper and lower endless conveyor belts for sandwiching a stem portion of a rush seedling while transporting the seedling seedling in a direction intersecting with the stem axis. In the cut-and-align device for rush seedlings, which is configured to cut the lower part of the roots and the tips of the ears, on the side of the supply port to the pair of endless conveyor belts, there is a mounting table on which the stalks of rushes are placed A guide slide, which is inclined from the placing table toward the supply port, is provided alongside, and a backing plate for abutting the lower part of the root of the grass seedling is provided upright adjacent to the placing table and the guide slide. .

[0007]

[Operation and effect of the device]

 With this configuration, a large number of bundles of grass seedlings are temporarily placed on the mounting table provided on the side of the endless conveyor belt for supplying the grass seedlings. After that, if the lower part of the root is pressed against the pad, the positions of the roots will be easily aligned. Since the placing table and the backing plate are separated from the conveying surface by the endless conveying belt, it is possible to calm down and place a large number of rush seedlings at this location.

[0008] Then, since the appropriate number of stocks are slid and moved from the above-mentioned mounting table to the supply port along the guide slide, the work procedure is improved, and since the lower part of the root is abutted against the above-mentioned pad, mud is applied to other parts. It is also possible to prevent the state of becoming dirty. As described above, according to the present invention, the cutting and arranging work of the grass seedlings is extremely easy.

【Example】

 An embodiment embodying the present invention will now be described with reference to the drawings. Fig. 1 is a left side view of a cutting and aligning device for grass seedlings, Fig. 2 is a front view taken along the line II-II of Fig. 1, and Fig. 3 is a right side view. 4 and 5 are plan views of a lower endless conveyor belt, and FIG. 6 is a plan view of an upper endless conveyor belt.

The cutting and aligning device 1 for rush seedlings is composed of a main body part A and a dolly part B. The dolly part B is a pair of front and rear pipe-shaped frames 2a and 2b bent downward in a U-shape and a lower end. A pedestal 3 provided with caster wheels 6, and the pedestal 3 is vertically movably fitted into the hollow columns of the frames 2a and 2b, and the pedestal 3 is drilled at different height positions. The locking pin 5 is inserted into the plurality of pin holes 4 and the height is adjusted so that the locking can be achieved.

The main unit A is supported by support members 7, 7 that connect the front and rear pairs of frames 2 a, 2 b on both left and right sides. In this machine section A, a lower endless conveyor belt 8 and an upper endless conveyor belt 9 are arranged so that the supply port 10 is on the left side and the discharge port 11 is on the right side in FIG. With the endless conveyor belts 8 and 9, the stem portion of the rush seedling I is sandwiched and conveyed in a direction intersecting the stem axis line (a substantially right angle direction). In that case, the pair of upper and lower endless conveyor belts 8 and 9 are arranged so that the conveyor surfaces thereof are inclined so that the stem axis of the grass seedling I is at an angle θ1 with respect to the horizontal plane (see FIG. 1). As a result, the tip of the rush seedling I can be conveyed in a state in which the tip end side is directed upward toward the front side of the machine unit A and the root part is rearward and downward.

Cutting means 14a and 14b composed of a pair of upper and lower disc cutters 12 and 13 are arranged on the front edge side and the rear edge side of the endless conveyor belts in the middle of the upper and lower endless conveyor belts 8 and 9 in the conveying direction. Then, the root lower part Ib and the tip part Ia of the rush seedling I are cut and cut to a length L (see FIG. 7). As described above, the stem axis of the rush plant I has an angle θ1 with respect to the horizontal plane, and the root portion is located downward, so that the root is less likely to hang downward with respect to the stem axis. It is possible to reliably cut the lower part of the root Ib of various lengths. Furthermore, as described above, the stalk axis is inclined, and the tip portion Ia of the rush seedling I is projected to the outside of the machine near the upper side of the frame 2a on the front surface side of the bogie portion B. It is possible to lower the height of the hand of the worker who holds the tip Ia side of the rush seedling I on the front side of A, and makes it easier for the worker to stand or sit on a chair to improve work efficiency. Can be improved.

As shown in FIG. 2, FIG. 4 and FIG. 9, on the left side of the supply port 10, the stem portion of the rush seedling I is located so that its root lower part Ib faces downward and its tip part Ia faces upward. The mounting table 51a to be mounted is arranged, and the guide slide table 15b extending from the mounting table 15a so as to incline toward the supply port 10 is provided alongside. The inclination angle of the guide slide 15b is approximately the same as the inclination angle θ2 (angle of the opening) on the starting end side of the upper endless conveyor belt 8 described later.

The mounting table 15a and the guide slide table 15b are integrally formed of a metal plate or the like in a character shape in a front view, and these are mounted on the left side surface of the cover body 16 of the lower endless conveyor belt 9 by a bracket. 17a and the overhanging rib 17b are fixed, while straddling the rear end side of the mounting table 15a having the width dimension (W1) and the guide slide table 15 and extending obliquely upward at a right angle to the upper surface thereof, and the supply port 10 The backing plate 18 is arranged so as to extend in the direction.

As a result, the grass seedling I on which the stem portion is to be placed on the placing table 15a can be aligned with the stem axial direction of the root portion very easily by contacting the lower part of the root with the contact plate 18. Wear. The grass seedlings I to be aligned in this way may be sent to the supply port 10 along the inclined surface of the guide slide 15a. The upper endless conveyor belt 8 and the lower endless conveyor belt 9 are notched in the vicinity of the supply port 10 so that the bottom plate Ib naturally hangs downward due to gravity. The portion to be cut) extends rearward from the cutting means 14b so that the cutting can be performed.

The contact plate 18 is slidably attached to a pair of upper and lower guide rails 20 and 20 fixed to the left side surfaces of the cover body 19 and the cover body 16 of the upper endless conveyor belt 8, respectively. The fixing means is used to position and adjust the cutting means 14b for cutting the roots. In that case, a gap plate 60 is provided so as to prevent the root lower part Ib from hanging in the gap between the rear edge of the mounting table 15a and the front side of the backing plate 18 (see FIG. 9).

Reference numeral 21 is a discharge guide for guiding the cut rush seedlings to the storage box 22, and reference numeral 23 is a box for storing the cut lower part Ib (chips) which is naturally dropped. The operator holds the tip of the rush seedling I by hand and accompanies the outlet 11. Next, the structures of the upper endless conveyor belt 8 and the lower endless conveyor belt 9 will be described with reference to FIGS. 2 and 4 to 6. The lower endless conveyor belt 9 is wound around a drive winding support roller 24 on the downstream side (right side in FIG. 2) in the transport direction and a winding support roller 25 for tension on the upstream side (left side in FIG. 2) in the transport direction. The lower drive shaft 27, which is hung and supported, on the wrapping support roller 24 is rotatably supported by the front and rear lower support frames 26, 26. The lower endless conveyor belt 9 is driven by a chain 31 wound around a chain sprocket 28 attached to the lower drive shaft 27 and a chain sprocket 30 of a drive motor 29 with a speed change mechanism arranged in the inner space of the lower cover body 19.

The large-diameter disc cutters 13, 13 are detachably and non-rotatably fixed to the cutting lower drive shaft 32 of the cutting means 14a, 14b rotatably supported by the lower support frames 26, 26. Driven by a chain 35 wound around a chain sprocket 33 of a drive motor 29 and a cutting sprocket 34 of a lower drive shaft 32, the rotation is driven. Both ends of a support shaft 36 for rotatably supporting the winding support roller 25 for tension are slidably supported by front and rear elongated holes 37, 37 formed in the lower support frames 26, 26 while the support shaft 36 is supported. The tension of the endless conveyor belt 9 is adjusted through the brackets 38 and the adjusting screws 39 attached to both ends of the belt.

When the idler roller 40 is positioned in front of the disc cutter 13 in the transport direction and near the overlapping portion of the disc cutter 13 and the upper disc cutter 12 (cutting point substantially along the transport direction), It is possible to prevent the position of the rush seedling I from shifting toward the center of the radius of the disc cutter 13 and improve the cutting action. The guide support plate 57 is attached to the outside of the rear lower support frame 26 via the bolts 58 and the brackets 59, and the root lower part Ib conveyed to the guide support plate 57 rides on the lower part of the root lower part Ib. It is possible to prevent drooping at a large angle with respect to the axis, and the cutting is more reliable.

The upper endless conveyor belt 8 is divided into an upper root side conveyor belt 8a and an upper tip side conveyor belt 8b in the lengthwise direction of the belt. The drive shaft 42 is rotatably supported by a pair of front and rear upper support frames 43, 43, and a gear 44 attached to the upper drive shaft 42 meshes with a gear 45 attached to the lower drive shaft 27 to rotate in a predetermined direction. To be done. Further, the small-diameter disk cutters 12, 12 are detachably and non-rotatably fixed to the cutting upper drive shaft 46 of the cutting means 14a, 14b, and the upper drive shaft 42 and the cutting upper drive shaft 46 are connected to the chain 47 and the chain sp. It is interlocked via the rockets 48 and 49.

The intermediate idler roller 50 in the upper endless conveyor belt 8 is separated into a small diameter roller 50b on the root side and a large diameter roller 50a on the tip side, and each is independently rotatably supported by a support shaft 51. ing. The idler roller 50 is arranged so as not to face the idler roller 40 in a side view on the upstream side of the disk cutters 12 and 12 in the conveying direction, and to be close to the lower endless conveying belt 9. On the other hand, the tension winding support roller 52 on the upstream side in the transport direction is disposed at a position apart from the lower endless transport belt 9 and the endless transport belt 8 from the wind support roller 52 to the idler roller 50. The extension direction of the conveying surface is greatly expanded and inclined (angle θ2) toward the conveying upstream side (supply side) with respect to the conveying direction of the lower endless conveying belt 9.

The support shaft 53 that rotatably supports the wrapping support roller 52 is slidably supported by the elongated hole 54 formed in the upper support frames 43, 43 so as to be pulled in the direction of the inclination angle θ2. On the other hand, the tension of the endless conveyor belt 8 is adjusted via brackets 55 and adjusting screws 56 attached to both ends of the support shaft 53. Thus, the intermediate idler rollers 50 and 40 of the pair of endless conveyor belts 8 and 9 which are driven at the same speed are arranged so as not to face each other upstream of the cutting means in the conveying direction. As described above, the action of preventing the slack of each of the endless transport belts 8 and 9 when the rush seedling I is carried while being sandwiched, and the squeezed grass seedling escapes to the cutting point by the roller cutter blades 12 and 13. There is an effect that neither the action of preventing it nor the damage is impaired.

Further, the extending direction of the endless conveyor belt 8 from the wrapping support roller 52 on the upstream side of the upper endless conveyor belt 8 to the idler roller 50 is upstream with respect to the extending direction of the lower endless conveyor belt 9. Since the winding support roller 52 is separated from the lower endless conveyor belt 9 and the idler roller 50 is arranged so as to approach the lower endless conveyor belt 9 so as to be largely spread and inclined toward the side, the supply of the rush seedling I is supplied. On the upstream side of the conveyance which is a part, a large gap can be opened so that the conveyance surface of the upper endless conveyor belt 8 is inclined at a large angle with respect to the lower endless conveyor belt 9. Therefore, it becomes easy to supply the plant of rush seedlings to the supply port 10 of the machine unit A, and it is easy to hold the plant. Moreover, since the position of the intermediate idler roller 50 on the upper endless conveyor belt 8 is merely located upstream of the cutting means 14a and 14b in the conveying direction, the above-mentioned two effects can be achieved without increasing the number of idler rollers installed. (The action of preventing the slack of the endless conveyor belt when the rush plant is carried while being sandwiched and the action of preventing the grass plant I to be sandwiched from escaping to the cut portion) can be achieved. The structure is simple and the manufacturing cost can be reduced.
