Abstract

FIELD OF THE INVENTION The invention relates to agriculture, in particular, to openers for a wide range of sub-seeding. The purpose of the invention is to increase the reliability and uniformity of seeding. The opener contains a lancet paw 1, located in the rack of the drive shaft 3, at the end of which there are windows 7 for outputting seeds to the disk vaned diffuser 8, and inside is a cone

distributor 9. The drive shaft is made in the form of a bevel gear. The opener has a safety device made in the form of spring-loaded semi-axes 17 fixed on the sides of the rack, interacting with grooves 18 mounted on frame 21 of brackets 19, seeds enter shaft 3 and then accelerator is received on diffuser 85 and are evenly distributed under curvilinear blades paw. The seeding rate depends on the size of the cone distributor. When a paw encounters a stone, the opener moves back due to its relative rotation around the gearing wheel 12. In order for the wheels 12 and 10 not to engage and the gears, the spring-loaded semi-axes 17 and the opener move in the grooves 18 of the brackets 19, 1 or more.

The invention relates to agriculture, in particular, to openers for variable subsurface sowing.

The purpose of the invention is to improve the reliability of operation and the uniformity of seeding.

The drawing shows the opener of the open sowing of seeds.

The opener of seed sowing of seeds contains a lancet paw 1, which is rigidly fixed on rack 2. At the same time, a hollow shaft 3, the mother-, is installed in the pointed paw and the rack under the visceral shaft. Rialpipe, which is fixed in the bearing units. The tocTOHT bearing units are made of rolling bearings 4, seal 5 and cover 6. At the working end of the hollow shaft 3 there are windows 7 for outputting seeds to the disk vane diffuser 8, and inside there is a cone distributor 9. At the other end of the shaft 3 there is a driven cone wheel 10 With the aid of a special nut 11, the bevel wheel 10 engages with a driving cone wheel 12e fixed to the intermediate shaft 13 and transmits movement to the shaft 3 via a key 14. A feeding socket 15 is attached to the nut 11, which is fixed by a retaining ring 16. The coulter has a safety device, which consists of two semi-axes 17 rigidly fixed on both sides of the rack 2 and freely in the slots 18 of the brackets 19. In the bracket 19 the semi-axle 17 is pressed by the spring 20 The brackets 19 are fixed on the frame 21 of the sowing machine.

The opener works in the following way.

When the coulter moves, the soil rises with the lapel paw 1 and passes over it. At the same time, a compacted seed bed is created under the paw 1. Seeds coming from the bunker are fed to the feed; the bell 15 and directly pass through it, a special nut 11 enters the shaft 3 - the material-wire, in the lower part of which there are windows 7. To ensure even feeding of the grains from the windows 7 shaft 3 on the diffuser 8 mounted cone distributor 9; the size of which depends on the rate of seeding. The seeds fed to the disk diffuser 8 receive acceleration due to the centrifugal force arising from the rotation of the diffusor B, and with the help of curvilinear blades are evenly distributed under the lancet paw 1, the disc diffusor 8 is driven from the tractor's PTO through the intermediate shaft 13 leading the wheel 12, which transmits movement to the driven cone wheel 10 and through the key 14 to the shaft 3. When the paw 1 meets the stone, an additional resistance force arises, due to what the springs 20 are compressed and the vomer departs as d due to its relative rotation around the wheel 12. In order to at this point are not out of engagement gears 12 and 10, supports in the form soshnik.imeet semiaxes brackets 17 and 19, i.e., spring-loaded axle shafts 17 and along with them the axes move in the slots.

18 brackets 19. Moreover, due to the driving wheel driven by the driven conical wheel 10 of the drive wheel 12, the toes of the lancet paw 1 are deflected when meeting the stone. After the obstacle is bypassed, the additional resistance force disappears and the compressed springs 20 return the vomer to its original position.
