Description

The technical field to which the utility model relates is. The plant for pelleting seeds relates to agricultural engineering, in particular to devices for presowing treatment of seeds.

State of the art

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 (RF patent No. 2620015), containing a cylindrical body, inside which there is a working body made in the form of bowls mounted on a common vertical axis, driven into rotational movement 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 there is a transporting device connected with the working body, on The case is equipped with a vibrator. This device is taken as a prototype.

The main disadvantage of the known installation for pelleting seeds is rotational and oscillatory motion. In this installation, the movement of seeds from one bowl to another bowl of the working body occurs due to the inertia of the movement of seeds. But in different bowls, the seeds have different weights, and one rotation speed cannot be suitable for all bowls of the working body. At a low rotational speed, the dragged heavy seeds due to inertia will be transferred from the lower bowl to the calibration sieve, and in the upper bowl the light seeds will simply stick to the edges of the bowl. At a high rotation speed, light seeds due to inertia from the upper bowl will be reloaded into the middle bowl, but heavy coated seeds from the lower bowl will fly out and break due to the high rotation speed of the bowl. In addition, when the vibrator is operating, upon reaching a certain critical mass of pelleted seeds, the pelleted mass will simply collapse from vibration. That is, in this installation, the process of seed pelleting is completely uncontrolled and with a lot of rejects.

Utility Model Disclosure

Brief Description of the Drawings

In FIG. 1 installation for pelleting seeds contains the upper bowl 1, the middle bowl 2, the lower bowl 3, the seed supply pipe 4, spray tubes 5, 7, 9, the re-pelletizing pipe 6, the pipeline 8 of the powdered coating materials, collapsible flange devices 10, the tilt device 11 of a cylindrical housing 20, a drive mechanism 12, a bearing 13 of a common hollow axis of rotation 21, a sloping board 14, a calibration sieve 15, a container 16 for incompletely drazirovannyh seeds, the hopper 17 of the finished product, the duct 18 for supplying warm air, air od exhaust air outlet 19, a cylindrical housing 20, the opening lever 22 vysypnyh gratings 25, the opening lever 23 vysypnyh gratings 26, the opening lever 24 vysypnyh gratings 27, all the levers 22, 23, 24 are located in the opening of the cavity 21, the axis of rotation.

Utility Model Implementation

Installation for pelleting seeds works as follows. Using the device 11, the tilt of the cylindrical housing 20 of the installation is set at a given angle in the working position. Exhaust grilles 25, 26, 27 are closed. The seeds to be pelleted are fed through the pipe 4 to the upper bowl 1 mounted on the hollow axis 21 in the cylindrical housing 20. The hollow axis 21 is rotationally driven by the drive mechanism 12. In this case, all the bowls 1, 2, 3 mounted on a common axis 21. Through a spray 5 in the upper bowl 1 under pressure, a finely dispersed suspension, consisting of dressing agents, growth stimulants and microelements, is portioned. If necessary, it is easy to dry the seeds from excessive moisture by supplying warm air through the duct 18 with exhaust air through the duct 19. After a predetermined time, the cylindrical body 20 of the pelleting plant is brought into a vertical position, with the lever 22 located in the cavity of the axis 21, the grilles 25 located around the axis 21 and the seeds come from the upper bowl 1 into the middle bowl 2, after which, through the lever 22, the discharge grilles 25 are closed and the cylindrical body Fitting 20 is installed vnaklonnoe position. A new batch of seeds is poured into the upper bowl 1 through pipeline 4 and a finely dispersed suspension is portioned through the sprayer 5, and the adhesive liquid is sprayed into the middle bowl 2 through the sprayer 7, after which the seeds coated with adhesive liquid are sprinkled with powdered components of the coating mixture through the pipe 8. Low rotation speed and the absence of vibration provides soft and high-quality coating of seeds with the components of the pelleting mass. After a predetermined time, by means of the tilt device 11, the installation cylindrical body 20 is installed in a vertical position, the discharge grates 26 of the middle bowl 2 are opened with the lever 23, also located around the axis 21 and the coated seeds fall into the lower bowl 3. With the lever 23, the discharge gratings 26 are closed and the discharge ones are opened the lattice 25 with the lever 22. As a result, the next portion of the pickled and treated seeds enters the middle bowl 2 from the upper bowl 1. After that, the discharge gratings 25 are closed, and the cylindrical installation housing 20 again takes a tilt using the tilt device 11. And now, in all three bowls 1, 2, 3, predetermined processes occur. A new portion of seeds enters the upper bowl 1 through a conduit 4, which is pickled and processed through a sprayer 5. In the middle bowl 2, the seeds are treated with an adhesive liquid and subsequently coated with powder components. And in the lower bowl 3, a reinforcing layer is applied through a sprayer 9 by means of a suspension of strengthening water-soluble components and fungicides to scare away birds and mice, followed by drying through a branch of the warm air supply duct 18 and the exhaust air duct 19. After the production process is carried out and the cylindrical body 20 is brought into vertical position with the arm 24, the discharge grates 27 of the lower bowl 3, located around the axis 21, open and the coated seeds pass through the ramp board 14 to the calibration sieve 15. The dragees that have reached the required size enter the hopper 17 of the finished product, where the final drying is carried out, and small dragees through the calibration sieve 15 enter the tank 16, from which they are sent for re-coating in the middle bowl 2 through the piping od 6.

The collapsible installation design makes it easy to rinse and clean the installation. The flowability of seeds and components is ensured by the adjustable rotation of the bowls 1, 2, 3, their tilt and drying of the supply and exhaust air system. This provides a layered application by the component, the same size and quality of coated seeds. Thus, the claimed design of the installation for pelleting seeds can improve the quality of pelleting seeds.
