Description

The scope to which the utility model belongs.

The utility model relates to agriculture, in particular, can be used in designs in the form of independent machines and built-in nodes of complex stationary and mobile agricultural machines.

The level of technology.

Known pipeline for gravity transportation of a heap of grain, consisting of a conveying pipe, including straight and curved sections with a guide element made in the form of a groove mounted obliquely in front of the curved section. The invention provides increased wear resistance of the pipeline and minimal damage to the seeds (see patent RU 2279386 C1 publ. 07/10/2006 Bull. 19).

This design allows you to move the material under its own weight only along a downward inclined pipeline. And if necessary, horizontal or vertical movement of the material, it is necessary to use other conveying devices that provide a given type of movement of the material.

A vertical screw conveyor for conveying bulk materials is known, including a cylindrical conveying pipe, a conveying screw located therein, connected to the drive, an unloading nozzle and a loading chamber in the form of a cone-shaped funnel covering the lower part of the casing and the open portion of the conveying screw covered by a tape spiral. The direction of the turns of the conveyor screw and the tape spiral do not match. The tape spiral, placed coaxially with the conveyor screw, is cantilevered with its lower end to the hub connected to the drive, which sits freely on the conveyor screw shaft and in the bottom of the loading chamber. The screw and spiral are installed with the possibility of counter rotation (see patent RU 2130418 publ. 05.20.1999).

The disadvantage of this design is the high trauma of seeds of agricultural crops as a result of falling into the gap between the conveying pipe and the screw.

A self-cleaning screw is known, consisting of a screw installed in a conveyor pipe on a screw shaft, containing perimeter holes with nylon threads fixed to them, consisting of three parallel threads passed through holes of the type of three-thread (see patent RU 2399573 C1 publ. 20.09. 2010 Bul. 26).

The disadvantage of this design is the complexity of manufacture and the presence of injury to seeds of agricultural crops due to the presence of clearance and movement of the screw relative to the conveying pipe.

The closest technical solution is the sowing apparatus of a grain seeder with a central metering of seeds. The sowing apparatus includes loading chambers, a metering device on the drive shaft, loading and unloading windows. The dosing device is made in the form of two pairs of cylinders fixed on the drive shaft with the possibility of rotation with different frequencies. On the inner surfaces of the cylinders, multi-start flat turns are arranged along helical lines. In one pair of cylinders, the turns are made with left-hand winding, in the other with right-hand. The bases of the outer cylinders are worn on the end parts of the receiving chambers. A U-shaped flap with an unloading window is installed between the cylinder pairs. Tedders are mounted on the end parts of the drive shaft. The invention will allow to eliminate damage to the seeds and to increase the uniformity of sowing seeds during slopes (see RU 2452165 C1 publ. 10.06.2012 Bull. 16).

The disadvantage of this design is the lack of a protective casing on rotating parts.

Disclosure of a utility model.

The objective of the proposed utility model is to develop a device for transporting seeds that will reduce injury to seeds and reduce energy and metal consumption of the structure.

The technical result that can be achieved using the proposed device is to reduce traumatizing seeds and reduce energy and metal consumption of the structure.

The technical result is achieved using a device for transporting seeds containing a drive, loading and unloading chambers, a screw with a shaft located in a transport pipe, which is additionally equipped with a carrier pipe, while the screw and shaft are rigidly connected to the transport pipe in a spiral of blades in a single structure, placed with a gap in the cantilever mounted carrier pipe, and it is also equipped with a bandage with a sliding support.

The reduction of seed injury is achieved by the fact that in the proposed design, where the screw is rigidly connected to the conveying pipe in a spiral of blades into a single structure, there is no gap between the conveying pipe and the screw, due to which the seeds are severely damaged when transported by shken conveyors, as well as the presence of the carrier pipe with bandages in one section of the transporting and supporting pipes provided with a sliding support. Reducing the energy and metal consumption of the structure is achieved by the fact that the screw, rigidly connected to the conveying pipe, is made of composite materials (for example, plastic).

A device for transporting seeds includes a drive, a screw located in a transport pipe, while the screw is rigidly connected to the transport pipe in a spiral of blades in a single structure made of composite materials (for example, plastic), placed with a gap in a cantilever mounted carrier pipe, provided in a free end face supporting element for auger shaft.

In one section of the transporting and supporting pipes there are bandages with a sliding support installed in them, made, for example, of a Teflon gasket.

Injury of seeds by screw conveyors is well known, but, nevertheless, the screw is widely used to move grain both horizontally and at an angle to it. The reason is the simplicity of design and low power consumption. The main injury occurs both due to the ingress of grains into the gap between the screw and the conveying pipe, and friction about them.

For one pass through a screw conveyor, it injures seeds of agricultural crops in the range of 1.2-6.0% (see Fadeev L.V. Grain cannot be beaten - it is the basis of human life [Electronic resource] // Access mode: http: // agrodovidka.info/post/7785 (11/10/2016)).

A brief description of the drawings.

In FIG. scheme of a device for transporting seeds.

Implementation of a utility model.

A device for transporting seeds includes a drive 1, a loading chamber 2, a screw 3 on the shaft (not shown in FIG.), Rigidly connected in a spiral fashion of blades (not shown in FIG.) In a single design with a transport pipe 4, for example, a screw 3 and a transport pipe 4 are made of a composite material (for example, plastic), then they are welded into a single structure by a welding extruder, placed with a gap in the cantilever supported carrier pipe 5, in one section of the conveying 4 and carrier 5 pipes there are bandages 6 provided with a sliding op 7, for example, made of a Teflon gasket, in the free end of the screw 3 there is a supporting element 8 for the shaft and an unloading chamber 9.

A device for transporting seeds works as follows.

The seeds of agricultural crops enter through the loading chamber 2 to the screw 3, driven by the drive 1. The seeds moved by the screw 3, enter the conveying pipe 4, which is rigidly connected in a spiral design with the blades in a single structure with the screw 3, due to which there is no the gap, severely injuring the seeds during transportation. On the supporting pipe 5 and on the transporting pipe 4, located in the supporting pipe 5, to impart structural strength, there are bandages 6 with a sliding support 7, in the free end of the screw 3 there is a supporting element 8 for the shaft, in the free end of the screw 3 there is a supporting element 8 for shaft. Next, the seeds transported by the screw 3 enter the discharge chamber 9.

Comparison of the claimed utility model with the prototype shows that the new is the reduction of seed traumatization due to the fact that the screw is rigidly connected in a spiral design of blades into a single structure with the conveying pipe, and the reduction in energy and metal consumption of the structure is achieved by the fact that the screw and conveying pipe are made of composite material.
