The invention relates to a protective seeding device with which the seed guards are placed on a growing medium. to a desired depth in the substrate, and a seed metering device for guiding the seeds into the substrate inside the seed cover, the metering device comprising a block part placed inside the tubular body and said seed hopper being in contact with said seed hopper.

The planting of the seeds of a plant to be sown in a forest planting instead of the seedlings is not advantageous other than placing some protection on the seeds sown in the planting area for the future seedling. Plastic conical seed covers, for example, have been used as such seed protection. Purely manual seed planting is cumbersome, time-consuming and ergonomically disadvantageous, and thus far too expensive, as a result of which a suitable protective plant achieves significant advantages and cost savings in forest planting.

Finnish patent application No. 761658 discloses a sowing lute, which makes it possible to sow seeds on a growing medium without manual work and to set a sowing cover to protect the seeds. A stack of a plurality of seed guards is arranged at the lower end of the tubular part and the device requires an ejection member for the individual removal of the seed guards. However, this known device has a complex solution and numerous drawbacks.

The device is prone to malfunctions because it removes the seed guards one by one from the stack of numerous seed guards at the lower end of the tubular part. In addition, the seed guards must be specially reinforced to withstand the stresses when pressed into the substrate.

Finnish patent application No. 771605 discloses a protective device that is very simple in structure and absolutely reliable. In this known protective sowing device, a presser ring is connected to the lower end of the tubular body part, which is adapted to receive and retain the sowing guard to be placed therein, and by means of which the sowing guard is pressed into the growing medium to the desired depth. The seed guard printed on the substrate is released from the press ring by lifting the seed guard upwards. In this known device, the seed metering device consists of a feeder in a compartment placed inside the tubular body part and a feeder counterpart attached to the tubular body part. The disadvantage of this known protective device is the complicated operation of the seed metering device. The metering device can often feed an unnecessary amount of extra seeds and often the seeds can also break.

It is a more detailed object of the invention to provide a protective seeding device in which the seed dispensing device is as simple as possible in operation. Yet another object of the invention is to provide a seed supply arrangement for a protective sowing device in which it is possible to adjust the volume of the seed space. It is a further object of the invention to provide a seed supply arrangement in which seed breakage cannot occur. Other Objects of the Invention And the advantages achieved by it will become apparent from the description of the invention.

The objects of the invention are achieved according to the invention by a protective seeding device, which is mainly characterized in that the operation of the seed metering device is operatively connected to the oscillating movement of the protective - 3 §7200 the transport of seeds in the hopper to the other end of the seed hopper, that when the seed drill is rocked back to a substantially vertical working position a few seeds are adapted to be transported to the metering unit in the seed hopper.

Numerous advantages are achieved with the seed drill according to the invention. In the protective seeding device according to the invention, it is realized to combine the seed metering with the oscillating movement of the protective seed. In the seed supply arrangement according to the invention, the seed volume can be adjusted, which is a considerable advantage. In addition, in the seed supply arrangement according to the invention, the seeds cannot break. When the seed feeding arrangement according to the invention is carried out using a seed hopper made of a transparent material, which is still preferably provided with a transparent cap, each seed feeding operation can be monitored.

The invention will be explained in detail with reference to some preferred embodiments of the invention shown in the figures of the accompanying drawings, to which, however, the invention is not intended to be exclusively limited.

Figure I shows a side view of a seed drill with a seed supply system according to the invention.

Figure 2 shows an axonometric view of the carrying and transporting means of the seed covers used in connection with the protective seeding device according to the invention.

Fig. 3 shows a side view of another embodiment of the seed hopper of the seed drill according to Fig. I.

Fig. 4 shows a top view of the seed hopper according to Fig. 3.

In the embodiment according to Figure I, the seed drill is generally indicated by the reference number 10. The seed drill 10 comprises a tubular body part II inside which a block part 12 is placed. The seed drill device 10 further comprises a remover 13 located at the lower end of the block part 12. The protective seeding device 10 further comprises a press ring 14, which in this embodiment is provided with a flange part 15. The press ring 14 is connected to the tubular body part II by means of ring binder holders 16. The protective seeding device 10 further comprises a hand grip 17 provided with a handle 18, a seed hopper 19 and a pressing device.

In the embodiment according to Figure I, the seed hopper 19 is preferably made of a visible material, such as a suitable plastic. Inside the seed hopper 19, for example, a funnel 20 with four arms 21 is placed. The upper end. The seed hopper 19 is further provided with a closing member, i.e. a cap 27.

The pressing device of the protective seeding device 10 comprises a baler body 23 and a presser handle 24. The presser body 23 is connected to a block part 12 inside the tubular body part II, e.g. by means of a spring pin 25. The press device further comprises a spring device 26 adapted to compress as the press body 23 moves downwards. The spring device 26 returns the press body 24 to its original position when the pressing handle 24 is stopped.

In connection with the protective seeding device 10 according to the invention, it is advantageous, but not necessary, to use the carrying and transporting harnesses of the seed guards according to Fig. 2, generally indicated by reference numeral 30. The harness 30 comprises a bracket 31, a harness belt 32 and a guide tube 33. The bracket 31 is provided with a hook-like part for support. The fastening loops or sleeves of the harness belt 32 are provided with, for example, suitable spring hooks 34. A suitable chain 35 is attached to one of the spring hooks 34. The chain 35 is attached to a suction screw 36 attached to one end of the flexible curtain cable 37. The cable screw 38 is attached to the end screw of the curtain cable 37. a threshing brush 39 or the like is attached. The tine brush 39 is adapted to receive a stack of a number of seed guards (not shown). In the embodiment according to Fig. 2, the three other spring hooks 34 in the harness belt 32 hang bottle brushes 39 supporting side protection stacks (not shown).

The operation of the seed feed of the seed drill according to Fig. I is as follows. The seeds are poured into the seed hopper 19 by removing the cap 27. The seeds are generally poured enough to form a seed layer about 3 cm high at the bottom of the seed hopper 19. The seeds in the seed hopper 19 are introduced into the dispenser by raising the seed rod 10 to the support 31 in the harness belt 32, whereby the seed rod 10 normally pivots slightly more than 90 ° from the vertical position, as a result of which the seed hopper 19 is directed slightly obliquely downwards. Due to such a oscillation I i, the seeds are transported in the seed hopper 19 to the 27 end of the cap. When the seed rod 10 is in the transverse position on the transverse hook-like member in the support 31, the seed brush stack 39 supporting the seed guard stack 37 is passed through the guide tube 33, whereby one seed guard to the working position, a few seeds pass through the hopper 20 Arm 21 through the bottom hole of the hopper 20 to the dose 22. When a suitable sowing location is found, the seed guard (not shown) placed on the press ring 14 is pressed into the ground with the seed rod 10 so that the lower part of the press ring 14 molds. At the same time, the pressing handle 24 of the pressing device is pressed downwards, e.g. with the thumb, whereby the block part 12 connected to the pressing body 23 of the pressing device also moves downwards. When the compartment part 12 has lowered by about 5 mm, the tubular body part II under the metering space 22 opens and the seeds can fall all the way to the sowing cover along the tubular body part II. Continuing to press the push handle 24, the release 13 at the lower end of the block part 12 detaches from the paint ring 14 of the seed guard, whereby the seed stick 10 can be lifted back into the support 31 in the harness belt 32 for the next work.

In the seed supply arrangement according to the invention, it is also possible, if desired, to adjust the dose level 22. For this purpose, the lower end of the block part 12 is provided with threads. Correspondingly, the release 13 is provided with threads. When the detacher 13 is screwed deeper into the thread at the lower end of the compartment 12, the nut-operated detacher 13 pulls the upper end of the compartment 12 deeper into the metering slat 22, thereby increasing the volume of the seed space 22. Correspondingly, the volume of the slement space 22 can be reduced by rotating the release 13 in the opposite direction.

The seed drill 10 according to Fig. I can be easily changed from right-handed to left-handed by turning the handle 17 around the tubular body part 180 by 180 °. The seed hopper 19 according to the invention is preferably made of transparent plastic, whereby the amount of seed is easily visible through the seed hopper 19. It is also advantageous to make the closing member, i.e. the cap 27, of the seed hopper 19 from a transparent material, whereby each seed feeding event can be easily seen and monitored.

Figures 3 and 4 show an alternative embodiment of a seed hopper according to the invention. In this embodiment, an inclined tubular member 120, preferably of transparent plastic, is attached to the inner wall of the seed hopper 119. The tubular portion 120 is provided with a longitudinal hole 122 in the seed portion 119 through which the block portion 112 is adapted to pass. The cap of the seed hopper 119 is indicated by the reference number 127. In this embodiment, the dosing space is formed by the upper part of the hole 122, i.e. the upper end of the block part 112 serves as the bottom of the dosing space 122. The volume of the dispensing space 122 can be adjusted in a manner similar to the embodiment of Figure I. The seed feed takes place in the embodiment according to Figures 3 and 4 in combination with the oscillating movement of the KyI belt stick 10 as in Figure! in an embodiment according to
