Description

The invention relates to the mechanization of agriculture, and in particular to devices for the uniform distribution and application of seed dressings prepared in dry and liquid forms.

A device for spraying seeds according to the copyright certificate SU No. 1688795, IPC A01C 1/08, publ. 11/07/91, bull. No. 41. The unit consists of a tractor with a spraying device mounted on it, equipped with a pump, water tanks and fittings. On the side of the tractor there is a plant for moistening cotton seeds before sowing, mounted on tractor spars, including a frame with an installed screw conveyor with a drive unit, a hopper with a seed metering device for processing and a liquid spray. The conveyor drive unit is connected to the tractor hydraulic system, and the liquid atomizer is connected to the sprayer water system through pipelines connected to the distribution valve. The screw conveyor includes a casing and a screw. The bunker-loading device consists of a casing with a metering device installed, which is made in the form of corrugated or smooth rollers. A liquid atomizer is installed in the tank capacity, connected to the sprayer fittings, and is supplied with water from the containers through the distribution system.

The unit operates as follows. Seeds are poured into the hopper. The metering device driven by the screw drive evenly, in the prescribed mode, feeds them to the screw conveyor casing, while the seeds in the hopper are moistened with water or an aqueous solution (with additives of biostimulants, etc.) with a spray. Next, the seeds, passing along the entire length of the conveyor, mixing, are transported to the final section for loading into the trolley, followed by drying and sowing.

The disadvantage of this device is that the unit requires additional loading equipment.

The prototype of the proposed device is a unit for seed dressing according to copyright certificate SU No. 1069657, IPC A01C 1/08, publ. 01/30/84, bull. Number 4. The treater consists of a frame on which a loading conveyor with a pick-up is mounted. The loading conveyor includes a screw and is equipped with a disk rigidly mounted on the shaft of the screw. The blade has blades facing the screw. The blades are welded to the disc and shaft. A screw mixer with discharge neck is installed on the shaft. Above the screw is a seed hopper with sensors. The work of the mechanisms of the treater is controlled by seed level sensors. The processing chamber is located next to the hopper and is separated from it by a partition with a slide gate. A sprayer is installed in the processing chamber. A tank for pesticides with an agitator and a dispenser is also installed on the frame, which is connected via a pipeline to a pesticide sprayer. The frame is mounted on two support wheels and one drive.

Treater is as follows. The seed dresser is installed in the immediate vicinity of the pile of seeds to be treated. Turn on the treater for automatic mode. The picker, which is a left and right tape auger, directs the seeds to the feed auger, which feeds their hopper with the help of blades, from which the seeds are fed through an open gate valve into the processing chamber, where they are processed with a suspension of toxic chemicals from the sprayer. In a screw mixer, the seeds are mixed with pesticides and discharged into bags through the discharge neck. Using the slide gate, the seeds are dispensed from the hopper into the chamber. The sensor controls the flow of pesticides into the atomizer. When the hopper is filled to the level of the sensor, the drive of the chassis is switched off.

The disadvantage of this device is that the machine is highly specialized, it performs only pickling, there is no universality, i.e. light workload during the year.

The technical task of the invention is to increase productivity by improving the working body of the treater and increasing the versatility of the front loader.

The technical problem posed by the invention is solved in a seed dressing device comprising a screw mixer, a tank for pesticides, a pesticide sprayer, characterized in that the screw mixer is a flexible screw mounted in a front loader bucket and connected to a drive shaft located in the bearings of the housing attached with the possibility of mounting-dismounting to the side wall of the bucket, on the output end of which a driven sprocket of a chain drive driven by a hydraulic ora mounted on the bracket on the rear wall of the bucket, and the opposite wall of the ladle shroud is attached, through flange in which holes connecting member mounted sprayers pesticides, radially spaced around the diameter of the casing and connected by means of flexible pipings capacity.

This design elements in the design of the prototype is not available.

A device for seed dressing consists of a bucket 1 (Fig. 1, 2, 3,4, 5), a flexible screw 2 and a removable container 3 (Fig. 8, 9,10). A flexible screw 2 is installed in the bucket 1, which is welded to the shaft 5 from the right side wall 4 of the bucket 1 (Fig. 7), and from the other auger 2 exits through the left side wall 6 (Fig. 6). Outside the bucket 1, the screw 2 is located in the flexible casing 7. The shaft 5 passes through the housing 8, in which it is seated on two angular contact bearings 9. The housing 8 is bolted 10 to the right side wall 4 of the bucket 1. A hydraulic motor is provided for driving the screw 2 11 and the chain drive 12. The hydraulic motor 11 is attached to the rear wall 13 of the bucket 1 using the bracket 14 and connected to the tractor hydraulic system. A removable tank 3 for pesticides is mounted on the boom 15 of the loader 16 using brackets 17. It is equipped with fittings 18 for supplying and discharging air and pesticides. In the casing 7 of the flexible auger 2 mounted nozzles 19 located in a checkerboard pattern along the entire diameter of the casing. The sprayers 19 are connected to the tank 3 by means of polyethylene or rubber pipes 20. To hold the casing 7 of the flexible screw 2, a removable bracket 21 is attached to the boom 15 of the loader 16. The pipes 20 connect the tank 3 with the tractor compressor 22 and the flexible screw 2.

The housing 8 is made of a welded construction and consists of a sleeve 23 and a flange 24. In the housing 8 there are two seats 25 for angular contact bearings 9. A sleeve 27 is installed in the seat 26 of the housing 8 from the side of the flexible screw 2, and is closed by a cover 28 The cover 28 is made of a welded structure, consisting of a sleeve 29 and a flange 30. A sleeve 32 is installed in the seat 31 of the cover 28. A driven sprocket 33 of the chain drive 12 is mounted on the shaft 5 of the housing 8 using a screw 34 and a key 35.

By turning on the hydraulic motor 11 through the chain drive 12, the flexible screw 2 is rotated. Due to the rotation, the screw 2, actively mixing, feeds grain from the bucket 1 to the casing 7. The compressor 22 is turned on, which creates excess pressure in the tank 3 and feeds toxic chemicals into the casing 7 of the flexible screw 2. In the casing 7 is the processing of grain by pesticides. Moreover, due to the rotation of the screw 2, the seed material is actively mixed with pesticides.

Pickled material is loaded into bags or other sealed containers. If necessary, the grain can be loaded into a vehicle, a seeder loader, or directly into a seeder.

The consumption of pesticides depends on the cross section of pipelines 20 and their quantity and is taken on the type, particle size distribution and physico-mechanical properties.

At the end of the dressing operation of the entire grain volume, the dresser is dismantled, for which the casing 7, the container 3, the chain drive 12, the flexible screw 2 with the shaft 5 and the housing 8, the pipelines 20, the hydraulic motor 11 are removed. For the loader 16 to operate normally with bulk and other cargo, so that the cargo does not wake up, through covers 47 are replaced by blank covers.

Grain pickling occurs in a sealed pipe and does not cause any inconvenience, and does not affect the environment, and the efficiency and versatility of the loader are significantly increased.
