Description

In the proposed machine for planting seedlings in cups, a planting machine of already known type is used, made in the form of endless chains, carrying clamps, which serve to feed cups into the furrow formed by the vomer. A feature of the proposed apparatus is that the supporting clamps of the rods are provided with props with rollers supported during the movement of the chains on the outer edge of the fixed frame.

In FIG. 1 shows a general side view of the car; FIG. 2 - top view of the car.

At the front of the machine, collet 9 is mounted, attached to rods 30 pivotally connected to the axis of the 2 rear wheels. Each coulter 9 can be installed in one position or another in height with the help of a chain 15, wound on a roller 16, on whose axis a handle 14 is mounted. Each landing gear of the machine consists of two endless chains 12, worn on sprockets 31, 32, 33 and 34. Tips 12 in the upper part of the landing gear are placed a fixed frame 42, along which supports 44 of holders 45 attached to the links of chains move on rollers 43. Hold (320)

whether they are fixed on chains at equal distances from each other, equal to the required distance between plants in rows. The holder is attached to the chain links by means of a plate 46, from the center of which a rod 47 extends. On this rod there are holders 45, which are forceps held in a closed state by a spring 48. can be lengthened or shortened with the help of the mobile bar 49. Decrease or increase the length of the holders is made 13 according to the size of the transplanted seedlings. The plates 50 are pivotally attached to the ends of the strips 49. The free ends of these plates are provided with thickenings in order to give the plates more weight. The cup, captured by the plates 50 from the conveyor 54, under the action of its own weight, and also due to the greater weight of the lower parts of the plates 50, when moving the chains of the landing gear will automatically assume a vertical position. The chain of the landing gear is set in motion from the rear wheels of the vehicle using a chain transfer 51. Transporter 54

mounted on racks 52 and 53 n has a width that matches the size of the cups. Nodal plates 57 are installed on the sides of the conveyor to prevent a fall. The speed of the conveyor should depend on the distance between the carriers of the landing chain. The change in the speed of the conveyor (this is due to the change of the chain gear 58.

Capturing cups from the conveyor 1 FOLLOWS as follows, Legs 59 closed forceps when approaching the conveyor 54; pass between two strips 60 attached to the guide frame 42 and come closer to them, as a result of which the forceps (holders) are opened so that the end of the conveyor 54 passes freely between them. When the holder plates 50 are above the very end of the conveyor, the knives 59 are released from the guide bars 60, the plates 50 under the action of the spring 48 capture the next cup and, due to the downward movement of the chains, carry it towards the share 9. under the action of the respective guides are closed (not shown in the drawing) and the plates 50 are consumed, releasing the cup. Zagortachs 11 additionally pitch the soil to the embedded plant.

The inclusion of all the mechanisms of the machine in operation is performed using the clutch 62, moved along the rear axis 2, by the lever 63.

The machine has a device for leveling the disposition of plants in transverse rows on subsequent passes, in order to ensure the correctness of the rows of disposition in two mutually perpendicular directions (square fit). Adjusting the arrangement of plants in rows is carried out by changing the speed of movement of the chains of the planting machines. To accelerate the movements of the chains, there is a second chain drive 64, parallel to the gear 51. With the help of the lever 63 and clutch 62, the landing gear can be connected to the other gear, and, in addition, it can be completely stopped for a while with an average clutch length .

The worker controlling the lever 63 is guided in the work along the furrows, previously carried out by the marker 3 in the direction transverse to the machine.

The subject matter of the invention.

A planting machine with a cupping device in the ground consisting of exciting and top-down stacker cups fixed on endless chains moving in their lower parts parallel to the ground at a speed equal to the forward movement speed of the machine, characterized in that rods fixed to endless chains of the landing conveyor, bearing clamps for the cups, are provided with props 44 with rollers 43 supported on the outer frame of the frame 42.
