The height of the supply port is adjustable.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a rush seedling aligning machine for cutting the lower roots and tips of rush seedlings to make the seedling length uniform.

[0002]

[Prior Art]

 Conventionally, a seedling aligning machine that cuts the rush seedlings into a certain length has been known in order to mechanically plant the rush seedlings by a transplanter. The conveyor belt of the rush seedling aligner was horizontal, so that the seedlings were transported horizontally.

[0003]

[Problems to be solved by the device]

 In this case, as shown in FIG. 8, the height Z of the supply port is set to about 100 cm in order to make it possible for the worker to easily supply the seedlings to the supply port while sitting on a chair. And the machine becomes larger. On the other hand, when the machine is downsized, as shown in FIG. 9, the operator has to bend the waist and send the seedlings to the supply port, which causes pain.

When the conveyor belt is in the horizontal direction, the problem other than the height of the supply port and the size of the machine is that the conveyor belt is conveyed between the conveyor belts 3'and 4 ', as shown in FIG. The roots of the seedlings that do not grow in the entire length of the seedlings hang down and become uncertain, resulting in uncertain cutting of the roots. It was possible to disconnect or not. In addition, in FIG. 10, 5'and 6'are cutting blades.

[0005]

[Means for Solving the Problems]

 The present invention uses the following means to solve the above problems. In other words, in the conveyor belt of a rush planting machine that cuts the roots and tips of rush seedlings to make the seedling length uniform, the side of the sprouting seedlings that faces the tips is inclined at a certain angle upward from the horizontal direction, The height of the part can be adjusted and the height of the supply port can be changed.

[0006]

[Action]

 Next, the operation of using the above means will be described. When seedlings are supplied, the height of the tips of the hands is high for easy work, and the height of the supply port is lower than that of the hands, which enables downsizing of the machine. In addition, since the conveyor belt is inclined and the root side is lower than the ear side, the angle at which the root hangs downward relative to the ear is small during cutting, which increases the certainty of cutting. The cut tips also drop after being cut and attached to the seedlings without much adhesion.

【Example】

 Next, an embodiment shown in the attached drawings will be described. 1 is a left side view of the rush plant of the present invention, FIG. 2 is a right side view thereof, FIG. 3 is a front view thereof, FIG. 4 is a side view of an upper conveyor belt 3, FIG. 5 is a plan view thereof, and FIG. Is a side view of the lower conveyor belt 4, and FIG. 7 is a plan view of the same.

The grass seedling aligning machine has the main body unit A mounted on a carriage unit B. As shown in FIGS. 1 to 3, the rush is inserted from the supply port 1 on the left side of the machine with the root on the rear side of the machine and the tip of the machine on the front side. It is nipped by a conveyor belt consisting of 4 and conveyed from the left side to the right side in Fig. 2 inside the machine. During the conveyance, the tips are cut with the cutting blade 5 and the lower end of the root is cut with the cutting blade 6, and the right side of the machine. Is carried out from the carry-out port 7. A supply guide 2 and a discharge guide 8 are attached around the supply port 1 and the discharge port 7, respectively. In such a structure of this machine, as shown in FIG. 1, the supply port 1, the conveyor belts 3, 4 and the carry-out port 7 are such that the front side of this machine is inclined X ° upward from the rear side. Is.

Here, the structure of the trolley B will be described. The caster wheels 9, 9 ... Are attached to the four corners of the lower surface, and the lower end of the inverted U-shaped outer leg portion 10. The legs are formed so that the legs 11, 11 ... Are inserted, and a unit supporting member 13 for mounting the unit is attached between the outer legs 10, 10. Then, in the leg portion, a locking pin hole is provided at a predetermined position of the outer leg portion 10, a plurality of locking pin holes 11a are provided in the inner leg portion 11, and the locking pin 12 locks at an arbitrary position. The height of the legs can be changed by selecting the locking pin hole 11a, and the height Y of the supply port of the main unit A mounted can be adjusted.

The inclination angle X of the conveyor belt of the machine and the feed port height Y must be determined in consideration of the efficiency of seedling alignment and the workability of the machine. Therefore, the transfer angle of seedlings means the angle of the seedlings with respect to the horizontal direction so that the relationship between the transfer angle of seedlings, the cutting condition of roots, and the free fall condition of the tips is the most appropriate position. In order to surely cut the roots, the angle is most certain when the angle of the seedlings and the roots is 90 °, and the angle is 0 °, that is, the ears. The closer it is to the horizontal surface, the more the roots hang down from the ears, making it more difficult to cut. However, on the other hand, when the angle is 0 ° and the ears are horizontal, the ears after cutting are separated and fall without contacting the seedlings after cutting, and as the angles approach 90 °. , The dropped tips touch the seedlings after cutting, which makes them unwell. Therefore, the transfer angle of the seedling, that is, the inclination angle X of the transfer belt or the like is set between 0 ° and 90 ° so that it is convenient for both the cutting condition of the root and the dropping condition of the cut tip. It should be decided.

Next, regarding the relationship between the transporting angle X of the seedlings and the optimum height Y of the supply port, the condition that is most easy to work in the seedling supply work of the operator is that of supplying the seedlings. This means that the height of the hand holding the tip of the seedling is fixed at the optimum position, and this height is about 100 cm. Therefore, when the seedlings are transported horizontally, that is, when X = 0 °, the height of the supply port is the same as the height at hand, as shown in the prior art, so that Y = about 100 cm. It will be. Then, as X approaches 90 °, that is, as the roots of the seedlings to be fed are lowered and inclined with respect to the tips, the height of the feeding port must be made lower than the height at hand, so Y Along with that, it must be enlarged. That is, when X = 30 °, Y = about 650-750 mm, when X = 60 °, Y = about 350-450 mm, and when X = 90 °, Y = about 300 mm is the optimum height.

Here, in selecting the optimum supply port height, it is necessary to consider a loosening machine that is continuously formed with the seedling aligning machine. The loosening machine is a machine for loosening and separating roots of rush seedlings, which have been divided into several strains from one plant, before being applied to a seedling liner. The main structure is that the root of the seedling is put on a roller equipped with a blade to loosen the root and the root is loosened and transported. Therefore, it is necessary to arrange the supply port 1 continuously to the transport device. is there. Further, as shown in the prior art, it is not convenient in terms of the structure of the machine that the conveyor belt is large such that the height is 100 cm or is too low. As a result of taking these into consideration, Y = about 650 to 750 mm was judged to be the optimum feed port height, and therefore a seedling aligner with X = 30 ° was optimal, and X = 30 °. In this case, there is no particular problem with the cutting of roots and the free fall of the tips. Therefore, the supply port of the machine unit A, the conveyor belt, and the like are configured to be inclined at an angle of 30 ° above the horizontal, and the carriage unit B normally sets the leg portion 10 to have a supply port height of about 650 to 750 mm. By making adjustments, it is possible to obtain a seedling liner that is easy to operate and has a good cutting condition of roots and dropping condition of cut ears.

Next, the configurations of the upper conveyor belt 3 and the stock conveyor belt 4 will be described. First, the configuration of the upper conveyor belt 3 will be described with reference to FIGS. 4 and 5. The upper conveyor belt 3 is divided into two parts in the length direction, and is composed of an upper root side conveyor belt 3a and an upper tip side conveyor belt 3b. Both belts are hung on the upper drive roller 14, the upper tension roller 15, and the upper idle roller 16, and are driven by the upper drive roller 14 being connected to the upper drive shaft 17 by a chain 18, The belt and other rollers are rotated. The upper tension roller 15 adjusts the tension of the belt by adjusting the screw 15a. The upper idle roller is composed of two rollers of different sizes and rotating independently. By applying the upper root side conveyor belt 3a to the small roller and the upper tip side conveyor belt 3b to the large roller, respectively. The gap between the upper and lower conveyor belts on the root side is larger than on the tip side. As a result, in the transfer of rush seedlings with a thin tip side and a thicker root, the control on the ear side is too weak to make it impossible to transfer, or the root is suppressed too much and the shoots are crushed. Therefore, it is possible to carry the material at the proper belt gap on both the tip side and the root side. Further, the upper drive shaft 17 is provided with the upper cutting blades 5 on both sides, and the cutting blades 5 are rotated to cut the seedlings. The upper conveyor belt cover 25 covers the cover and rollers, and is fixedly connected by a lower conveyor belt cover 26 and a support member 27, which will be described later.

The lower conveyor belt 4 is wound around a lower drive roller 19, a lower tension roller 20, and a lower idle roller 21, and the drive roller 19 is connected by a chain 22 from a drive shaft M1 of the motor M, To drive. Like the upper tension roller 15, the lower tension roller 20 operates the screw 20a to adjust the tension of the belt. Further, a lower drive shaft 23 having a lower cutting blade 6 attached to both sides is arranged via a chain 24 from the drive shaft M1 of the motor, and the lower cutting blade 6 is driven to engage with the upper cutting blade 5 by biting. Then, the seedlings are cut. The lower conveyor belt and rollers are covered with the lower conveyor belt cover 26.
