The opener according to claim 1, characterized in that the bell for seeds is placed in the center of the passive zone of the blocked left-side and right-handed razors, a seed divider is installed at the lower end of the bell for seeds, the faces of which are located along the longitudinal axis of the blocked left-side and right-handed paws razors. ! 3. The opener according to claim 1, characterized in that on the lid, closer to the ends of the blocked left-side and right-hand razor paws, earthing devices are installed at an angle to the direction of movement of the opener.

Description

A useful coulter model for simultaneous fertilizer application, weed control and seed sowing refers to agriculture. Modern seeders are not adapted for simultaneous separate fertilizing and sowing seeds. Fertilizers, according to agricultural requirements, should be applied 3-4 cm deeper than the seeds.

Existing disc coulters have low resistance, provide satisfactory quality of sowing, but do not destroy weeds.

Known disc coulter with depth gauge, seed guide funnel, with an elastic reflector (AS No. 586360) does not separately fertilize when sowing seeds and does not destroy weeds.

Soshnik (AS No. 904542) has a disk, lancet paw, augers with a drive, feed channels. The main disadvantage is the complexity of the design and unreliable work in a complex soil environment (sticking, weeds, dust, etc.).

Also known is a combined opener (A.S. No. 1018591). It has a housing, two discs, a bell for fertilizers and a bell for seeds with a lancet paw, in the passive zone of which there is a seed distributor having a vertical dividing plate. However, when the discs are tilted, a vertical dividing plate narrows the passage section of one of the channels and violates the uniform distribution of seeds. This coulter is selected as a prototype.

The purpose of the utility model is to simplify the design, fulfill the agrotechnical requirements for separate fertilizer application and sowing seeds.

The goal is achieved due to the rigid connection of the single-disc opener with interlocked left and right paws-razors, the blades of which are located 3-4 cm above the lower point of the disc.

The proposed opener for strip sowing of crops with simultaneous separate application of fertilizers and seeds includes a disk, a bell for fertilizers, a bell for seeds, a seed distributor and lancet paw. The lancet paw, according to the utility model, is made in the form of interlocked left and right paw razors that are rigidly connected to the disk and also mounted 3-4 cm above the bottom point of the disk. The bell for seeds is placed in the center of the passive zone of the blocked left-side and right-hand razor paws. A seed divider is installed at the lower end of the socket for seeds, the faces of which are located along the longitudinal axis of the blocked left-side and right-hand razor paws. On the lid, closer to the ends of the blocked left-side and right-hand razor paws, earthing devices are installed at an angle to the direction of movement of the opener.

The opener is depicted in figure 1 - side view; figure 2 is a top view.

The coulter consists of a bell for fertilizers 1, a disk 2, a bell for seeds 3, a scraper-anchor-bed forger 4, a seed distributor 5, a cover 6, zagortachki 7, interlocked left-hand razor paw 8 and right-hand razor paw 9, as well as a leash 10 .

The coulter works as follows. The disk 2 with the scraper-anchor-bed-former 4 during the movement of the coulter form a furrow 6-8 cm deep. Fertilizers are fed to the bottom of the furrow through the bell for fertilizers 1. The blocked left-side paw-razor 8 and right-hand paw-razor 9 loosen the soil at a depth of 4-5 cm and cut weeds. Through the bell for seeds 3, the seed distributor 5 seeds are divided into two streams and scattered under the blocked left-side paw-razor 8 and right-hand paw-razor 9, and the seeds are not sown over the furrow with fertilizers.

Zagortachki 7, mounted on the lid 6 at a certain angle to the direction of movement of the coulter, fill the furrow formed by the coulter and take the trimmed weeds to the surface of the soil. The cover 6 is used to protect the seed distributor 5 from the ingress of soil and to secure the earthenware 7.

Preliminary tests have confirmed that the utility model allows agrotechnical requirements for separate fertilizer application and seed sowing to be met. In addition, it was found that if a single-disc opener without interlocked left-side and right-side razor paws at an optimum depth (3-4 cm) covers 60-63% of wheat seeds, then with these razor paws - 78-80%.
