[0001]
[Industrial applications]
INDUSTRIAL APPLICATION This invention is used for the seedling machine of the field effect | action which transplants the seedling (also called cell seedling) grown in the pot.
[0002]
[Prior art]
A plurality of pots are provided integrally in a seedling box side by side, front and rear, left and right, and a technique for growing seedlings by putting floor soil in each pot has been established. Various types of seedling transplanters for mechanically transplanting the seedlings have been proposed and used for trials, but have not yet been established.
[0003]
[Problems to be solved by the invention]
The present invention proposes a new seedling-planting device, thereby trying to make a seedling-planting machine for transplanting pot seedlings for field action closer to a more feasible one.
[0004]
[Means for Solving the Problems]
According to the present invention, in order to solve the above-described problems, seedlings 7a are grown in seedling boxes 6 in which a plurality of pots 6b are provided side by side and in front and rear, and the seedlings 6 are turned upside down with the seedlings 7a facing sideways. A seedling box transfer device 8 for sending, a pushing device 9 for pushing the root mortar 7b in the pot 6b to the seedling 7a side, a seedling sending device 18 for sending the extruded seedling 7a, and a transplant for receiving the seedling 7a and transplanting it to the ground The seedling feeder 18 is provided with a plurality of holding needles 24 on an endless body 23 that rotates around a vertical drive shaft 19 so that the tip of the holding needles 24 swings up and down. It is provided so as to be supported by rails 26 from below on the vicinity of the seedling box 6 sent by the box transfer device 8 and on the cup 28 of the seedling planting device 27 and circulate sideways . Root mortar 7b pushed out sideways when passing near Provided to the rail 26 is the root ball 7b is scraped look down interrupted when passing over the Rutotomoni cup 28, when the holding pin 24 has come in front of the seedling box transport device 8, A seedling plant is characterized in that the tip is lifted by the rail 26 and faces the direction of the pot 6b .
[0005]
[Action]
The seeds are sown by putting floor soil in each pot 6b and irrigated, and after a predetermined number of days have elapsed, the seeds germinate and the seedlings 7a grow. At this time, the root extends along the inner wall of the pot, and the root extends together to form a root pot 7b having the same shape as the pot 6b. While the seedling box 6 is being sent upward or downward by the seedling box transfer device 8, the root mortar 7 b is pushed out toward the seedling 7 a side by the pushing device 9. At this time, since the circulating holding needle 24 faces the seedling 7a in the horizontal posture, the holding needle 24 is inserted into the root mortar 7b by the above-described extrusion. When the holding needle 24 is supported from below by the rail 26 and circulates sideways and comes over the cup 28, the rail 26 is interrupted and changes its posture downward, after which the inserted root is inserted. The pot 7b is scraped off from the holding needle 24. Then, the root mortar 7b is received by the cup 28 of the seedling planting device 27 together with the seedling 7a, and then the cup 28 descends and reaches the ground, and transplants the received seedling 7a. Then, when the holding needle 24 turns and comes to the front of the seedling box transfer device 8 again, the tip is lifted by the rail 26 and the next root pot 7b is inserted in the direction of the pot 6b.

[0012]
The cup 28 of the seedling plant 27 is provided at a position where the tips of the holding needles 24, 24. That is, an L-shaped support frame 30 is provided at the rear end of the pair of links 29, 29 vertically, and moves up and down while maintaining the same posture by the swing of the links 29, 29. A beak-shaped cup 28 is provided on the support frame 30, the front and rear beaks are closed above to receive the seedling 7 a in the cup 28, and the lower beak protrudes into the ridge A below and the closed beak is opened, and the seedling 7 a is opened. Separately transplant to the ground.
[0013]
The scraping device 31 is configured as follows. A pair of disks 32, 32 are arranged on the machine frame 34 back and forth so as to rotate together with their respective horizontal axes 33, 33. The pins 35, 35 protrude rightward from the outer peripheral portions of the disks 32, 32, and the bases of a pair of scraping rods 36, 36 are rotatably mounted on the front pin 35, and the rear side is inserted into the elongated hole 36a in the middle. When the pin 35 is inserted and the disks 32, 32 rotate at the same rotational speed, the rear ends of the scraping rods 36, 36 rotate clockwise. Then, the rear ends of the pair of left and right scraping rods 36, 36 rotate on the left and right sides of the holding needle 24 hanging on the cup 28. Accordingly, when the holding needle 24 into which the root mortar 7b is inserted comes over the cup 28 in a downward position, the left and right scraping rods 36, 36 scrape the root mortar 7b from the holding needle 24, and the seedling 7a The user enters the cup 28 in an upward posture.
[0014]
In the apparatus shown in FIG. 3, the pins 15, 15,... Move forward when the left-end holding needle 24 into which the root mortar 7b is inserted passes the right-end pot 6b, and the six root mortars 7b, 7b are pushed forward and inserted into the respective holding needles 24, and thereafter, the seedling box 6 is fed down by one row. The chain 23 for rotating the holding needles 24, 24,. However, intermittent rotation may be used, but the following configuration is also possible. That is, the seedling feeding device 8 and the extruding device 9 are provided so as to reciprocate right and left, and the rightward moving speed and the turning speed of the chain 23 are the same among the moving speeds. Then, the roots 7b, 7b,... Pushed out by the pins 15, 15,... Are inserted straight into the respective holding needles 24, 24, and the seedlings 7a, 7a,. Work can be speeded up.
[0015]
The means for pushing out the seedlings from the seedling box and transferring them to the cup 28 can be configured as shown in FIG. That is, the seedling box 40 is formed by piercing a plurality of pots 40b, 40b,... On the thick plate 40a. The pots 40b, 40b... Are similarly arranged with the above-mentioned pots 6b, 6b... In front and rear and left and right, and small holes 40d, 40d. The seedlings 7a, 7a,... Are grown in these pots 40b, 40b,.
[0016]
The seedling boxes 40 are arranged vertically with the seedlings 7a, 7a,. The seedling box 40 is sent to the right by a transfer device (not shown) and reaches the lateral end, is sent downward by the distance between the upper and lower pots 40b, 40b, and then is sent to the left to come to the lateral end. After being sent downward as described above, the transfer to the right is repeatedly performed.
[0017]
An air cylinder 41 is provided rearward in front of the seedling box 40, in which a piston 43 pushed forward by a spring 42 is housed, and a piston rod 43a projects rearward. A small hole 43b is provided in the piston 43 and the piston rod 43a, and a pad 44 having the small hole is fixed to the rear end. The air in the air chamber 45 is blown into the front end of the air cylinder 41 via a valve 46. When the seedling box 40 moves and the pot 40b containing the seedlings 7a comes after the piston rod 43a, the valve 46 opens and the high-pressure air in the air chamber 45 enters the air cylinder 41. Then, the piston 43 moves backward and the pad 44 hits the bottom of the pot 40b, and the air in the air cylinder 41 enters the pot 40b through the small hole 43b and the small hole 40d, and removes the root mortar 7b therein. It blows out later with the seedling 7a. After the root mortar 7b is blown out, the valve 46 closes and the air in the air cylinder 41 escapes, and the piston 43 and the piston rod 43a return to the original state by the spring 42.
[0018]
A guide plate 47 that falls backward is provided behind the seedling box 40, and the cup 28 moves up and down thereunder. Therefore, after the blown-out seedling 7a is received by the guide plate 47, it is poured into the cup 28 on its slope, and then the cup 28 descends and transplants the seedling 7a to the ground. With this configuration, the mechanical configuration is reduced, and the performance of the transplant is stabilized.
