RU186648U1 - FERTILIZER-ADDITION TO THE PNEUMATIC SEEDER FOR TREATMENT OF SEEDS WITH BIOLOGICAL PRODUCTS - Google Patents

Abstract

The utility model relates to agricultural engineering, in particular to dressers, and is intended for installation on a pneumatic seeder and seed coating with biological products during sowing. A seed dresser-attachment to a pneumatic seeder for seed treatment with biological products contains a container for working fluid 1, metering pump 2, a mixing chamber 3, with a sprayer 4 mounted in a pneumatic seed tube, a collection of surplus biological products 5, a branch pipe 6 and a screw surface 7. At the entrance to the mixing chamber is installed a helical surface with a number of turns from 1 to 3, a diameter equal to the inner diameter of the mixing chamber, and a pitch of turns of 1.5 ... 3 times its diameter. The swirling flow of air and seeds passing through the helical surface ensures uniform distribution of the biological product in the mixing chamber and, therefore, its uniform and complete application to the seeds. In addition, the swirling of the air flow minimizes pressure losses during the passage of the seeds of the mixing chamber and reduces the possibility of clogging. The invention was created with the financial support of the Russian Ministry of Education and Science in the framework of the Federal Target Program "Research and Development in Priority Directions for the Development of the Russian Science and Technology Complex for 2014-2020" Agreement No. 14.610.21.0017 of October 3, 2017, a unique identifier for the project RFMEFI61017X0017.

Description

The utility model relates to agricultural machinery, in particular to dressers, and is intended for installation on a pneumatic seeder and coating seeds with biological products during sowing.

A device is known according to patent RU 2161394 C2, consisting of a hopper, sprayer with a system for supplying working fluid and an unloading conveyor, the design of the seed loader for the sowing complex "Kuzbass" according to patent RU 2217897 C2. A device is also known according to patent RU 2144754 C1 for seed treatment in a seeder, consisting of a container for working fluid, a mixer with a sprayer installed in a pneumatic seed tube, a collection of excess pesticides and a branch pipe.

The disadvantages of the known devices are the uneven coating of the surface of the seeds.

The prototype of the utility model is a device that includes a container for the working fluid, a mixing chamber, with a sprayer installed in a pneumatic seed tube, a collection of excess pesticides and an outlet pipe. The mixing chamber is installed behind the sprayer and is a tube rolled up in the shape of a conical spiral in the direction of the seeds. The inner surface of the pipe is made in the form of diametrically alternating annular elevations and depressions, for example corrugations (patent RU 2483514 C1).

A disadvantage of the prototype is that the large length of the mixing chamber, rolled in the form of a conical spiral, leads to a loss of pressure and, consequently, to an increase in energy consumption and the likelihood of clogging of the pipe with seeds.

The technical task of the utility model is to increase the efficiency of seed treatment with biological products.

The technical result consists in the fact that the treater-attachment to the pneumatic seed seeder for biological products, containing a container for the working fluid, a mixing chamber, with a sprayer installed in the pneumatic seed tube, a collection of surplus biological products and an outlet pipe, is equipped with a screw screw installed at the inlet to the mixing chamber a surface with the number of turns from 1 to 3, a diameter equal to the inner diameter of the mixing chamber, and a pitch of turns of 1.5 ... 3 times its diameter. The swirling flow of air and seeds passing through the helical surface ensures uniform distribution of the biological product in the mixing chamber and, therefore, its uniform and complete application to the seeds. In addition, swirling air flow minimizes pressure loss during the passage of the seeds of the mixing chamber and reduces the possibility of clogging.

The essence of the utility model is illustrated by the diagrams shown in figures 1 and 2 (Fig. 1 - General diagram of a pneumatic seeder with a pickle attachment; Fig. 2 - Screw surface).

The treater-attachment to the pneumatic seed drill for biological treatment of seeds contains a container for the working fluid 1, a metering pump 2, a mixing chamber 3, with a sprayer 4 installed in the pneumatic seed tube, a collection of surplus biological products 5, a branch pipe 6 and a screw surface 7.

The proposed device operates as follows. Seeds dosed by the pneumatic seed drill seeding system are picked up by the air flow and fed into the mixing chamber. From the tank for the working fluid, the dosing pump sends the biological product to the atomizer, which atomizes it in the form of an aerosol. A mixture of air, seeds and aerosols twisted by a helical surface passes through the tube of the mixing chamber, where the seeds are intensively coated with a biological product.

Part of the biological product that didn’t get onto the seeds is deposited in the collection of excess biological products and is again sent for processing through the branch pipe. The air flow swirling with a screw surface allows you to maintain a uniform density of the aerosol cloud inside the mixing chamber, which ultimately leads to a uniform and complete coverage of the treated seeds with a biological product.

The use of this utility model allows to increase the efficiency of seed treatment with biological products.

The invention was created with the financial support of the Russian Ministry of Education and Science in the framework of the Federal Target Program “Research and Development in Priority Directions for the Development of the Russian Science and Technology Complex for 2014-2020” under agreement No. 14.610.21.0017 of October 3, 2017, a unique project identifier RFMEFI61017X0017.
