Description

The invention relates to agricultural machinery, in particular, to combined crops that can be used for the simultaneous sowing of seeds of grain and grass crops.

Combined crops are known, containing a bunker for seeds of various crops, sowing machines, double-disc coulters and t13 mortars.

 The disadvantage of these splines is uneven embedding of seeds of grain crops, since disc coulters have extremely uneven depth (cm). In addition, after the passage of the disc coulters, an extremely uneven soil surface is formed, and this contributes to uneven and deep planting of grass seeds, as a result of which the germination of grass seeds after the passage of the specified NWT-3,6 seed in some cases is 50. In addition , the presence of zagortach of the indicated forks in the form of chains with a uniform magnitude of the thickness of the links does not ensure a uniform embedding of the seeds of grain and grass sown to different depths.

The purpose of the invention is to increase the uniformity of sowing of seeds of two different crops to a predetermined depth.

The goal is achieved by the fact that, in a combined bucket containing a bunker for seeds of different crops, seeding machines, double-disc coulters and loops, the coulters' disks are made of different sizes in diameter and thickness, the small-diameter coulters disks are thicker, and the loops are made in the form installed on spring-loaded racks of chains with variable thickness of links, with chain links of greater thickness | mounted behind larger opener coulters. FIG. 1 is a side view of the combined crop; FIG. 2 is a flow chart for sowing a combined crop. The combined grain crop on a spill (Fig. 1) contains a bunker consisting of tanks for seeds of grain 1, herbs 2 and a seed dose of mineral fertilizers 3. sowing devices (-6, wired 7 and 8, double-disc coulters 9 s discs 10 and 11, frame 12, spring pillars 13 with hooks And, on which zagortachs are fixed in the form of a chain. 15 Disc coulters 9 are arranged in two rows with a spacing of 15 cm (figure 2). The combined disc coulter 9 consists of two discs of different diameter and thickness: an ordinary thin disk 10 (thickness mm) larger, diameter and tsiggindriches The cue disk 11 (thickness mm depending on soil type) is of smaller diameter. The difference between the diameters of disks 10 and 11 of the combined opener 9 is selected from the conditions of the sowing depth of grain and grass crops. The chain 15 consists of sections with different sizes of its links. Moreover, in the wake of a flat ordinary disk 1 O, an area with links of a larger one is installed, and behind a cylindrical 11 - with smaller links. The mill works as follows: During the work of the combined seed, the seeds of grain crops and the sowing dose of mineral Dobrenite .From sowing apparatuses C and 6 tukosem flows through wire 8 to a flat disc 10 of larger diameter, and the seeds of grass seed on wire 7 to a cylindrical disc 11 of small diameter. The cylindrical wide disc 11 leaves a shallow groove (Fig. 2) in which the grass seed arrives. The cylindrical disk 11 also serves as a depth limiter for the course of the disk combined coulter 9, which, with its increased support surface, allows to obtain a stable depth for the sowed crops. The flat disk 10 leaves a deeper groove (Fig. 2), 8 which is fed with grain and mineral fertilizers. Uniform soil embedment of unequal depths of grooves from the passage of flat 10 and cylindrical 11 discs is achieved by storing chains mounted on spring racks 13 due to the fact that its larger links are installed behind the flat disc 10, and smaller links behind the cylindrical disc 1 1. Thus, uniform filling of the grooves of uneven (unequal) depth is achieved. The proposed combined crop can combine seeding at the same time with other types of materials such as, for example, mineral fertilizers and seeds of grain crops or tuk, grass seeds, etc. The use of this combined crop allows to achieve the optimal seeding depth and uniform seeding of the seeds of two opposite crops simultaneously sown at different depths, which ensures more uniform shoots and the simultaneous development and ripening of the cultivated crops, and the formula of the invention of Combined Seed containing a bunker for seeds of various crops, sowing machines, double-disc coulters and coders, in order to increase the uniformity of sowing of seeds different crops at a predetermined depth, the coulter disks are made of equal diameter and thickness, the small diameter coulters disks are thicker, and the lock-overs are designed as chains mounted on spring-loaded racks with varying thickness of links, while the chains of greater thickness are mounted behind the coulter disks larger diameter.
