EXPERIMENTAL RESEARCHES ON THE PROCESS OF WORK OF THE BLOOD CONVEYOR OF THE MODULE OF HARVESTING
TOPS OF ROOT CROPS

Mechanized harvesting of roots is a labor-intensive and energy-intensive technological operation in the general aspect of agricultural crops production and their processing.

The analysis of the known scientific works allowed to state, that practically there are no results of experimental researches, which characterize the width of the roll of the crushed hinge, which is formed by a screw conveyor in the process of operation of the self-assembly module of single-phase coronal-cutting machines.

One of the reserves for raising the performance indicators of the hinge assembly modules is to improve the process of collecting the hinge by improving the working bodies to assemble the main array of hinges.

In this regard, the development of new and improved working bodies for the collection of root crops and the study of the influence of their parameters to improve the performance of gun-harvesting machines is an important national economic task.

Experimental studies to determine the width of the formed roll, conducted to determine the functional patterns of the influence of input factors, or parameters of the working bodies and the conditions of operation of the hook assembly module to the output, or the optimization parameter. The three-factor experiment was conducted at three levels of variation by factors, that is, a planned factor experiment of PFE 33 type was implemented.

An improved design of the module for harvesting the hinges of root crops was proposed by us. These improvements were respectively confirmed by Ukraine's patents for a useful model.

The regression equation is obtained, which characterizes the change in natural quantities. According to the regression equation obtained on the basis of the approximating empirical mathematical model, a response surface and a two-dimensional section of the surface of the response of the functional change of the width of the formed roll cut by a rotary hitch crew and a conveyor on a harvester conveying a felled beet root crop as a functional are constructed.

On this basis, one could argue that developed a theoretical model that functionally describes the change width formed roll concluded on harvested field chopped tops depending on the parameters of screw and technological parameters of module for harvesting fodder tops of root crops in the overall context for analytical level adequate or satisfactory way describes the real process of change The width of the formed roll formed on the collected field of the crushed wick, which was obtained at the empirical level according to the regression equations.

From the standpoint of the system analysis of the technological process of self-propelled root cropping machines that perform a single-phase method for harvesting root crops, it can be argued that the expediency of experimental studies of the width of the formed roll formed on the harvested field by a screw conveyor of the shredded root crop is regulated by ensuring the working efficiency of the vehicles involved in partially unloading the collected root crops From the full bunker of the root cropping machine without its stopping.

In this respect, the width roll formed technology is an important indicator of process module for harvesting fodder tops of root crops, thus to ensure the manufacturability of vehicle width formed windrow of chopped tops should not be greater than the center distance drives a vehicle or the width of the transport path. In most cases, as a rule, the width of the transport line of technological transport during the harvesting of roots is 1.8 m.

Then we can say that getting limits of theoretical and experimental widths formed windrow of chopped tops of root crops do not exceed 1.6 m wide track transport technology transport 1.8 m, that is scattered across the surface tops chopped harvested fields will not interfere with normal movement of the vehicle ( the absence of towing engines of the vehicle).

One of the reserves for raising the performance indicators of the hinge assembly modules is to improve the process of collecting the hinge by improving the working bodies to assemble the main array of hinges.

In this regard, the development of new and improved working bodies for the collection of root crops and the study of the influence of their parameters to improve the performance of gun-harvesting machines is an important national economic task.

The introduction of new highly efficient harvesting complexes, built on the basis of original constructive decisions of the working bodies, is the basis for further development of the agrarian complex of Ukraine. Existing single-phase technology and technical equipment used in the harvesting of root crops does not provide established performance indicators, which results in losses of 20% of the dry weight of root crops, and the available content of the hips in the collected root crops significantly reduces the quality of raw materials and the output of their processing products. In this aspect, raising the technical level of hinge-assembly modules of single-phase machines is an actual scientific task. The regression equation of the change in the width of the formed roll of the crushed hinge was obtained, depending on the parameters of the screw conveyor and working conditions according to the results of experimental studies of the improved module for harvesting fodder tops of root crops are received. It is established that in the given limits of variation of input factors (module speed, productivity of root cushions, rotational speed of a screw) the width of the formed roll of the crushed bundle is in the range from 0.5 to 1.4 m. The obtained research results are the next step in developing a method for optimizing the parameters of machines for harvesting root crops.
