Description

[Detailed description of the device]

[0001]

[Industrial applications]

 TECHNICAL FIELD The present invention relates to an opening / closing device for a grass seedling aligning machine, which is capable of opening the upper part of a lower conveyor belt for gripping and carrying the grass seedlings.

[0002]

[Prior art]

 In the past, both upper and lower conveyor belts were used in an aligner for aligning seedlings by sandwiching the upper and lower conveyor belts to convey the seedlings while cutting the tips of the foliage and root of the seedling with a cutter. Belts and the like remain incorporated inside the aircraft.

[0003]

[Problems to be solved by the device]

 However, when seedlings are clogged between the upper and lower conveyor belts, it is difficult to remove and clean the rush seedlings, sometimes the aircraft has to be disassembled, and maintenance is poor. There is.

[0004]

[Means for Solving the Problems]

 The present invention has been devised to solve such a problem and to provide a simple structure for easy cleaning.Therefore, the upper conveyor belt and the cutters on both sides thereof are installed on the upper support frame. In addition, the side portion of the upper support frame is pivotally attached to a stay extending upward from the lower support frame equipped with a lower conveyor belt so as to be rotatable around the fulcrum, and the side opposite to the fulcrum is formed. A locking device is interposed between the upper support frame and the lower support frame.

[0005]

[Action]

 Therefore, when the lock device is released and the upper support frame is rotated about the fulcrum, the upper side of the lower conveyor belt can be opened while the upper conveyor belt and the cutters on both sides thereof are lifted upward. As a result, the clogged seedlings can be easily removed and each part can be easily cleaned, and the maintainability is improved.

【Example】

 1 to 6, FIG. 2 shows a front view of the hay and grass seedling aligning machine, and inside the lower support frame B having four supporting legs 6 at the bottom, a horizontal upper surface is provided with roots 1b to foliage 1a. A wide lower conveyor belt 2b on which the entire rush seedling 1 can be placed is stretched, and a supply base 7 and a discharge base 8 are obliquely installed on the start end side and the end side of the belt 2b, respectively. On the upper part of the stay 5 extending upward from the side part of the lower support frame B, the side part of the upper support frame A is pivotally mounted so as to be rotatable around a fulcrum 0, and is moved downward until it abuts against the stopper 9. The upper conveyor belt 2a, which is short and narrow in the longitudinal direction, is capable of being clamped and conveyed between the lower conveyor belt 2b and the lower foliage conveyor belt 2b. It is stretched inside and is laterally lateral to the upper conveyor belt 2a. Constitute Kakarioku belt 10 for feeding engaging the root portion 1b of Igusanae 1 from above stretched to.

Disc-shaped cutters 3a, 3b capable of cutting the tip side of the foliage portion 1a of the rush seedling 1 are mounted on the upper and lower sides of one side of the belts 2a, 2b, which are intermediate portions, and Disc-shaped cutters 4a, 4b capable of cutting the tip side of the root part 1b of the rush seedling 1 are axially mounted on the upper and lower sides of the end side, and are horizontally laid parallel to the inner sides of both belts 2a, 2b. The cutters 3a, 4a and 3b, 4b are mounted on both ends of both rotary shafts 11, 12, respectively, and the rotary shaft 11 is transmitted to the upper conveyor belt 2a and the mooring belt 10 via a sprocket chain 13. The rotary shaft 12 is connected to the lower conveyor belt 2b via a sprocket chain 14 while being connected.

A drive sprocket 16 on the side of the motor 15 mounted in the lower support frame B, a sprocket 17 at the end of the rotary shaft 12, a sprocket 18 at the end of the rotary shaft 11, and a sprocket 18 at the upper support frame A. A chain 23 is mounted on a sprocket 22 at the tip of a tension arm 21 that has one end pivotally supported 19 on the front surface and is pulled upward by a tension spring 20. A lock device C is interposed between the lock device C and the lock device C. The lock plate 25 has one end pivotally supported 24 on the lower support frame B side, and the knob screw 26 is attached to the other end side to lock the lock plate 25. The recess 27 formed in the plate 25 is configured to be engageable with the pin 28 on the upper support frame A side.

Therefore, when the rush seedlings 1 are fed onto the lower conveyor belt 2b from the supply table 7, the rush seedlings 1 are clamped by both belts 2a and 2b and conveyed in the direction of arrow A. The tip side of the foliage portion 1a and the root portion 1b of the rush seedling 1 are cut by the cutters 3a, 3b and 4a, 4b, respectively, and the rush seedling 1 is cut to a predetermined length as shown by B in FIG. The seeds are aligned and discharged from the discharge table 8. However, when seedlings are jammed between the belts 2a and 2b, the tension arm 21 is rotated downward as shown in FIG. 23 is removed from the sprockets 22 and 18, and the lock plate 25 is rotated downward while the knob screw 26 is loosened and unlocked, and as shown in FIG. Up direction When turned to, the upper conveyor belt 2a, the cutters 3a, 4a, etc. can be lifted upward while the upper portion of the lower conveyor belt 2b can be opened, so that the jammed seedlings can be easily removed and cleaned. It can be done, and the maintainability is improved.

FIG. 7 shows another example, which is substantially the same as the above-described embodiment as indicated by the same reference numeral, but the motor 15 side, the rotary shaft 12, the upper conveyor belt 2a side, and the lower conveyor belt 2b side. Is connected via a chain 29, and the upper conveyor belt 2a side and the rotary shaft 11 are connected via a chain 30 so that maintenance can be easily performed.

Further, FIG. 8 shows still another example, which is configured in substantially the same manner as shown by the same reference numerals as the above-mentioned embodiment, but the drive shaft 31 of the motor and the rotary shafts 11 and 12 are connected to the chain 32. The motor drive shaft 31 and the lower conveyor belt 2b are connected to each other via the chain 33, and the upper conveyor belt 2a can be driven by the rotary shaft 11 to facilitate maintenance. It is the one.

[0012]

[Effect of device]

 As described above, according to the present invention, when the lock device C is released and the upper support frame A is rotated around the fulcrum 0, the upper conveyor belt 2a and the cutters 3a, 4a on both sides thereof are lifted upward and the lower conveyor belt A is lifted. Since the upper part of 2b can be opened, the clogged seedlings can be easily removed and cleaned, and the maintainability can be further improved, which is suitable for a simple structure. It has features that can be implemented.
