PLANTING TUBE FOR LAKE PLANTS - FÖR KLIMPPLANTOR AVSETT PLANTERINGSRÖR

This invention relates to a planting tube through which a planter drops a clump of seedlings into a pit made by the planting tube. The planting tube is then pulled out of the ground and the soil around the seedling is compacted to allow the seedling to take root properly in the ground. The implantation tube comprises a tube with a handle having a fixed jaw at its lower end cooperating with the pedal to open the jaw by depressing the pedal, and the implantation tube is provided with a spring-loaded locking and release mechanism fixed jaw for new planting.

Planting tubes of this type are already known. For example, FI patent publication no. 50033 discloses a planting device comprising a tube with a handle at its upper end, the lower end of which has a blade for making a planting pit in the ground and this blade consists of a fixed jaw extending to the lower end of the tube after which the actuating member is a foot lever attached to a pivoting jaw, which is mounted on a fixed jaw and is further provided with a latch and release device for holding the pivoting jaw in the open position and releasing it in the closed position.

Furthermore, FI patent 63318 discloses an implantation tube in which a different opening and closing mechanism of the pivoting jaw is arranged. This device has fixed pivots on the side edges of the fixed jaw in an upright position passing through the center line of the planting tube, on which a movable jaw is mounted and a U-shaped bracket lever with a leg lever on the other side of the planting tube. The jaw locking device comprises a substantially vertical resilient metal wire attached to the opposite side of the fixed jaw, in which a vertically spaced bend at the top and bottom dead center is made. The locking device further comprises a lug, which is an integral part of the movable jaw and is mounted on a wire-side articulation pin, the tip of which has a pin diverging slightly laterally. The brace lever is attached to one end of the foot lever at an acute angle downwards and the length of the crotch arms extends from the top of the movable jaw to the pivot pins so that when the foot lever is depressed -2- 7 6 90 9 the arch portion of the brace in the rotational motion, the pin disengages from the bend at the top dead center and slides on the surface of the wire into the bend at the bottom dead center, locking into it by the elasticity of the wire.

Other previously known planting means with an openable jaw are presented, for example, in SE-Kuulutus in not 1 + 1 + 3 ^ 071 and Hh3x697 as well as in FI patent applications 8505 ^ 9 and 851 + O8O. All of these devices have an opening jaw that moves the ground to the side when making a planting pit, but the opening jaw is away from the planter. Thus, once the planting is complete, the planter must move to the other side of the seedling in order to properly seal the ground around the seedling displaced by the pivoting jaw of the planting tube. Because the planting work is a contract work that is marked by great urgency, the compaction has not shown that the soil has been properly compacted, but the seedlings come off the soil when they are raised.

The object of the present invention is to provide a planting tube with which a reliable planting result can be easily obtained without slowing down or complicating the planting work. This object is achieved by making a planting tube in which the movable jaw of the blade faces the planter and not outwards from the planter, as is the case with the known planting tubes. The invention is characterized in that the upper part of the pivoting jaw is mounted with a bolt-nut connection on a pedal, which in turn is mounted at the top with a bolt-nut connection on levers mounted with a bolt-nut connection on a lug made on the side of the tube. the top of the jaw facing the tube, opening the planting tube and making a pit in the ground.

The invention will now be described with reference to the drawings, in which Figure 1 is a perspective view of the planting tube opened as seen from the right side of the planter and Figure 2 shows the planting tube as seen from the left side of the planter.

The planting tube according to the invention comprises at its upper end a tube (2) with a handle (1), from the upper end of which the seedling to be planted is dropped into a pit made by the planting tube. For this purpose, the lower end of the pipe has a fixed jaw (3) which is attached to the pipe (2), e.g. by welding. Attached to this fixed jaw (3) is a planting depth stop (H) with a bolt and nut, the end of which has a perpendicularly downwardly turned stop (5) which, when inserted into the ground, ensures that the planting tube remains in place after being planted.

At the top of the fixed jaw (3) there are articulated pins (6) fixed to the plane of the longitudinal center line of the tube (2), by means of which the pivoting jaw (7) is mounted on the fixed jaw (3). The pivoting jaw (7) is 1.5 times narrower than the thickness of the fixed jaw (3) below the pivot pins (6). In turn, the pivoting jaw (7) moves the ground ahead more easily to the side, because the pivoting jaw has split the soil layer when the pipe is hit into the ground. In addition, when the pivoting jaw (7) is slightly shorter than the fixed jaw (3) in the part below the pivot pins (6), the fixed jaw (3) does not move when the pivoting jaw (7) moves aside.

There are pins at the ends to keep the pivot pins in place. The second articulation pin (6) (Fig. 1) is provided with an extension (8) mounted on a safety pin spring (9), the upper ends of which are movably arranged in vertical guide fittings (10), one of which is attached to the implant tube (2) and the other of the swivel jaw ( 7) at the top. Thus, when the pivoting jaw (7) pivots to the open position, the safety pin spring (9) can move freely in the guide fittings (10).

At the top of the pivoting jaw (7) there are lugs (11) through which a bolt (12) is inserted, which is locked in place by a nut (13). This bolt forms a joint between the pedal (1U) and the swivel jaw (7). At its upper edge, the pedal (1U) is fastened by a bolt-nut connection (15) to levers (16) which are fastened at one end by a bolt-nut connection (17) to a lug made on the side of the planting tube. When pedaling the pedal (s) down with the foot, etc. bolts; thanks to the brothers (13 and 15, 17) the pivoting jaw (7) presses from its upper end towards the tube (2) and the jaw opens at its lower end so that the seedling can be dropped through the planting tube into the pit made by the pivoting jaw (7).

The locking and unlocking mechanism of the pivoting jaw (7) comprises a slide (18) which moves vertically back and forth in a guide tube (19) attached to the side of the tube (2). The slide (18) is provided with an internal thread to which the release rod (20) of the slide (18) is attached. The slide (18) is locked to the release rod by a nut (21), which also allows the position of the slide (18) to be adjusted vertically. A sleeve (23) is fastened to the trigger rod (20) with a locking screw (22), someone rests against the spring (2U) of the trigger rod (20). The spring (2 ^) is a compression spring, - 6 6909 which is against its upper end against a spring support (25) in which a slot is made for the removal and replacement of the release rod. At its upper end, the release rod (20) is attached by a bend to a rocker arm (26) which is operated by the thumb of the right hand (Fig. 2) by pushing the other end of the lever downwards.

When the pedal (1 ^) is pressed down from the position of Fig. 2 to the position of Fig. 1, the pivoting jaw (7) facing the planter opens and makes a pit for the seedling to be planted. When the jaw (7) turns, the safety pin spring (9) is tensioned. When the upper edge of the pivoting jaw (7) hits the lower end of the slide (18), which is rounded according to Fig. 1, the jaw (7) pushes the slide (18) upwards and the release rod connected to the slide (18) compresses the spring (2b). As the jaw (7) continues to rotate, the slider (18) finally slides to the top of the jaw to one side and the compression from the spring (2k) is released. In this case, the slide (18) comes down and locks the pivoting jaw (7) in the position of Fig. 1 when it rests against the upper edge of the jaw (7). The seedling can then be dropped from the top of the planting tube. When the planting has taken place, the planter presses the other end of the rocker arm (26) down with the thumb of the right hand (Fig. 2), whereby the release rod (20) rises, squeezing the spring (2k) again. At the same time, the slide (18) rises so much that the pivoting jaw (7) is released and due to the compression of the safety pin spring (9) the pivoting jaw (7) closes, i.e. against the fixed jaw (Fig. 2). In this case, the planting tube is again ready to be driven into the ground for the next trout planting. To dampen the impact caused by the impact, the handle (1) is attached to a spring arch (27) made of flexible steel, which gives the trajectory according to the intensity of the impact. By removing the bolt-nut connection (12, 13), the pedal ('\ k) can be turned parallel to the pipe (2) to the transport position.
