Introduction
Decree of the President of the Republic of Uzbekistan #PF-4947 dated 7th February 2017 "Actions strategies on further development of the Republic of Uzbekistan" and Resolution of the President of the Republic of Uzbekistan #PK-3459 dated 4th January 2018 "Supplementary measures to increase agricultural equipment" [1; 2] shows its valuable importance in mechanization of this sphere.
Lessening energy and resources in economy, the use of energy saving technologies for production, wide use of being restored energy sources, increasing labor productivity in economy sphere are set up in the 3rd chapter 3.2 part, 7 item in the Strategy of Actions of development the Republic of Uzbekistan in the period of 2017-2021 years, and 3 chapter 3.3 part is indicated works which are being performed in the sphere of agriculture "Modernization the agriculture and develop it intensively" [1].
Nowadays the most part of cotton growing appropriates to irrigated farming. Nevertheless cotton growing in irrigating agriculture demands more labor forces, it is considered preferable for high yields productivity. Because of crops' area relf and uneven fields related with the cotton irrigating pro-
cess will be implemented better by means of dividing pawls on the small fields. In this process along and across cotton pawls should be implemented before irrigating and use it till the end of crops period. Taking into consideration and making it quantities with all agricultural means is considered the actual problematic issue. Nowadays this process is being carried out by means of manual work at certain farmers. Manually made capsizer creating surface pawls is also being used. This device does not give an opportunity to use widely because of creating across pawl between cotton raw doing aggregate in twice, the height of hurting cotton young growth. As solution of such kind of problems the scientists are doing research work according to create. This by technical means to form two longitudinal aggregating get done among a number of cotton past the threshold, at the same time to injure the cause of the high level of the germination of cotton-wide, there is no allow you to apply. The solution of this problem by scientists as among a number of active cotton Bukhara branch of the Tashkent Institute of Engineers for Mechanization and Agriculture to form a longitudinal threshold screw work conducts scientific research in the
creation of the device. Recommended his new device has many advantages, particularly the lack of negative effects on cotton and energy economical, and other advantages of the threshold implementation as a form i.e. in transition.
Novelty of this recommended assembly which is created along pawl between cotton rows is defended by useful patent model № FAP 00671 by the intellectual property of the Republic of Uzbekistan.
Among the news of the longitudinal threshold as recommended assembly cotton pawls this form of utility model patent at the Intellectual Property Agency of the Republic of Uzbekistan is protected by № FAP 00671. The soil for the
purpose of lifting and transport device at a specific angle from the body of work screw were used.
Checking results of theoretical research conducted on the creation of this device working parameters and modes of the body of his work experience program in research in order to study the effects on the productivity of the work of bodies in laboratory conditions of energy section, and provided the basis of the parameters.
A number of longitudinal experimental studies among cotton the threshold in accordance with the program to form the model for conducting experimental research in laboratory conditions of the device prepared (Fig.1).
Figure 1. Laboratory assembly to investigate technologic process of creating along pawl device between cotton rows
From the model envisaged for the implementation of this laboratory prepared the following research work:
- work up the soil in relation to the direction of the movement of the body screw to set the angle of rotation of screw of his work due to the speed of movement and the number of studies on the productivity effects.
- blade raised in relation to its axis of screw of the corner to determine the effect on work productivity;
- screw its energy and agronomic performance to determine the effect of step diameter;
- experience using the planning method from which many of the working body to determine the value of parameters and modes of rational use.
A special laboratory to conduct research in the context of the laboratory experience and prepared the design of the device (Fig.1).
The laboratory device consists of the following parts: the soil of the channel 1, the wheelchair can move freely 2, (elec-
tric engine) 3, 4 screw the body of work of body work to set up a special device acting the wheelchair 5, the direction of the body in relation to the full settings available work actions a combination of the situation device 6 to transfer the rotary actions in the plane perpendicular to the body ofwork reducer device 7, become in the process of offering expenses out of the wheelchair due to the number of the chain gear 9, gear star shaped 10, 11 and 12 consists of a gear between the straps 13 forming pulley.
The device works in the following order of laboratory. The soil moving device that can move freely while the wheelchair 2 to channel 1 (electric engine) 3 moves forward. Experience device (screw body work) 4, 5 through a special device mounted to the wheelchair 2. The working action of the straps to the wheelchair body 2 through 13 screw 4 gear mounted cone special from 7 reducer device works out. Laboratory work in relation to the direction of movement of the device 6 is replaced by the slope angle combination of the body 4 screw. I am handling
the removable device in the laboratory experiment the results from the soil's volume 8 will be evaluated through.
To change the angle of inclination relative to the movement of the laboratory device from 0 to 75 degrees on the reverse side of the support, a threaded connection 6 is installed.
The main working element of the device at this angle the soil laboratory work screw carrier body 4, the rotary movement of the wheelchair's forward stationary be tried along with her 2 two-storey chain of 7 to 10 through the gear 9 to come to action from the reducer device in the shape of star cone, committing three gear rotary motion out of it that shaft making in diameter from 11 to 13 by straps 12 divided parts pulley of the screw is transmitted. Pulley that purpose through the change of level of the soil's rotation due to the rotary motion, which removes screw through this change and to determine the optimal number of parameters is designed to achieve. Laboratory model of creating along pawl between cotton rows' assembly is prepared according to working organ size 1/3 and fixed to soil channel cart through special device creating along pawl in soil channel laboratory assembly, gives an opportunity to practice several speed movement in operation modes (Fig.2).
