Description

The invention relates to agricultural machinery, in particular to a device for presowing seed treatment.

A well-known mixer-pelletizer of seeds (AS USSR No. 1817970, publ. 05/30/1993, bull. No. 20), comprising a housing, loading and unloading nozzles, a working body mounted on the shaft, made in the form of coaxially arranged spirals, while spiral have opposite windings with a semi-oval shape and are installed with the possibility of pouring seeds from one spiral into another.

In this analogue, the angular velocity of rotation of the disk is low, which does not allow to obtain a high-quality coating of seeds with coating materials.

A device for pelleting seeds is known (AS USSR No. 1824042, publ. 06/30/1993, bull. No. 24), containing a frame on which is mounted with a slope to the horizon on the shaft of the bowl with a sealed cover, a spray of adhesive and located inside the bowl a mechanism for mixing the seeds, while in order to expand the functionality it is equipped with a pneumatic system for supplying dry powder dressing, a hollow pipe and a cylindrical mesh drum mounted inside the bowl and having a rotation drive consisting of a gearbox and with an electric motor connected to the shaft through a gear wheel and fixed to the bottom of the drum with a hole, the shaft is rigidly connected to the disk and, using a rolling bearing with the bottom of the bowl, is hollow and a hollow pipe of the pneumatic system is coaxially mounted in it, which is connected by means of a bearing rolling with the shaft and communicated through the hole of the disk with the cavity of the drum.

The disadvantages of this analogue are: the uneven deposition of dragee components on the seeds due to the simultaneous rotation of a large volume of seeds in the bowl without high-quality mixing and the cyclical process of dragee.

The closest set of essential features is the installation for pelleting seeds (A.S. USSR No. 301116, publ. 06/01/1971, bull. No. 14), containing a cylindrical body, inside which there is a working body, made in the form of bowls mounted on a common a vertical axis driven in rotational motion from the drive mechanism, guiding funnels, a calibration sieve installed under the bowls and located in the lower part of the housing, with a sloping board, at the outlet of which a transport device is connected associated with working body.

The main disadvantage of the installation for seed pelleting is the uneven coating of the seeds with the components of the pelleting mass due to the absence of adhesive when dragging the seeds and the working body only performs either rotational or oscillatory motion.

The invention consists in the following.

The objective of the invention is to improve the quality of pelleting seeds.

EFFECT: possibility of preliminary applying adhesive liquid to seeds before coating them with coating components and providing both rotational and oscillatory movements of the working body of the device to improve the quality of seed coating.

The specified technical result is achieved by the installation for pelleting seeds, containing a cylindrical body, inside which there is a working body made in the form of bowls mounted on a common vertical axis driven in rotational motion from the drive mechanism, guiding funnels, a calibration sieve installed under the bowls and located in the lower part of the body, with a sloping board, at the exit of which a transporting device is installed, connected with the working body, while inside the body, above each bowl minutes posted spray liquid adhesive which is connected via a tube to the conduit, wherein the vibrator is disposed on the housing. Each tube is installed through an opening in the housing, which is covered by a corrugated cover.

The essential features affecting the achievement of the claimed technical solution are:

- placement inside the housing, above each cup of spray gun adhesive;

- connection of the adhesive fluid dispenser to the pipeline by means of a tube;

- placement of the vibrator on the body;

- installation of tubes through holes in the housing;

- sealing of each hole in the housing with a corrugated cover.

The invention is illustrated in FIG. 1, which shows a diagram of a plant for pelleting seeds.

Installation for drazhirovanie seeds contains a cylindrical body 1, inside which is located the working body, made in the form of bowls 2 mounted on a common vertical axis 3, driven in rotational motion from the drive mechanism 4, guiding funnels 5, a calibration sieve 6, mounted under the bowls 2 and located in the lower part of the housing 1, with a sloping board 7, at the outlet of which a conveying device 8 is connected, connected with the working body. Inside the housing, above each cup, an adhesive liquid atomizer 9 is placed, connected by a tube 10 to a pipe 11. A vibrator 12 is installed on the housing 1. Each tube 10 is installed through an opening in the housing 1, which is closed by a corrugated cover 13.

Installation for pelleting seeds works as follows.

The seeds to be pelleted are fed into the upper bowl 2 mounted on the vertical axis 3 in the cylindrical housing 1. The vertical axis 3 is rotationally driven from the drive mechanism 4. In this case, all the bowls 2 mounted on the vertical axis 3 rotate. The number of bowls 2 and guide funnels 5 corresponds to the number of components that make up the pan coating mass. Moreover, the components are fed to the seeds sequentially.

Simultaneously with the supply of seeds for pelleting to the sprayers 9 through the tubes 10 from the pipeline 11 is supplied under pressure created, for example, by a compressor, an adhesive liquid. The tubes 10 are inserted into the holes made in the cylindrical body 1. The tubes 10 are inserted into the holes so that one end of the tubes is located at the place where the seeds are spilled into the bowl 2 for drazhirovany, and the other outside the cylindrical body 1. Corrugated covers are put on the tubes 10 13, hermetically sealed openings in the cylindrical housing 1. The use of such covers avoids damage to the tubes during vibrations of the cylindrical housing 1. The cylindrical housing 1 is mounted on springs and has the ability to oscillate from vibrations torus 12 with a predetermined frequency.

The frequency of vibrations of the housing 1 and the frequency of rotation of the working body necessary for high-quality seed pelleting are determined experimentally, depending on the mass-geometric parameters of the seeds.

The atomizers 9 located inside the cylindrical body 1 create a finely dispersed state of the adhesive fluid. Due to the fact that the bowls 2 make a complex movement due to their rotation and oscillations, the seeds in the bowls 2 move randomly, which ensures that they are coated with adhesive fluid from all sides.

Seeds coated with an adhesive fluid are sprinkled with the components of the pelleting mass.

The supply of adhesive fluid is carried out at all stages of coating the seeds with the components of the coating mixture.

As the dragee mass increases, under the action of centrifugal force, the seeds are ejected through the bent edge of the upper bowl into the guide funnel 5 and then into the downstream bowl 2, where the dragee continues. From the lower guide of the funnel 5, the coated seeds go to a calibration sieve 6, which separates the seeds into fractions. Qualitative, from the point of view of pelleting, the seeds enter the finished product bin. Seeds, not fully or partially not treated, on the ramp board 7 are sent to the transporting device 8, which are sent for re-panning.

Thus, the claimed constructive implementation of the installation for pelleting seeds allows you to pre-apply adhesive liquid to the seeds before coating them with the components of the coating mixture and provide both rotational and oscillatory movements of the working body of the device and thereby improve the quality of drazhirovanie seeds.
