Description

The utility model relates to agricultural engineering, to devices for monitoring and signaling the progress of the technological process by agricultural units, namely, monitoring the sowing of seeds.

Known metering apparatus, consisting of a housing with upper and lower windows for the passage of bulk materials and a shaft located in the housing with a metering coil, driven by a stepper motor (RF patent No. 2263436, IPC A 01 C 7/12, 10.11.2005) .

The known apparatus allows for uniform seeding, however, simple mechanical dosing rigidly ties the operation of the apparatus to the design of the metering coil and completely eliminates the possibility of regulating the seed rate (for example, when switching to another crop or changing the seeding rate).

There is also a known method of controlling the metering system of the seeder and a device for its implementation, including a slotted window with a shutter controlled by an electromagnet located in the hopper of the seeder, a seeder speed sensor and a processor with a control panel electrically connected to the speed sensor and an electromagnet (RF patent No. 2273979 IPC A 01 7/00, 04/20/2006).

This device allows you to excite the shutter oscillations by pulsed signals of a certain frequency and duration, which leads to the expiration of the sown material from the hopper with a given seeding rate. This system is more flexible and easy to use, because the pulse duration corresponds to a predetermined seeding rate of a particular crop and therefore it has become possible to change the seeding rate if necessary.

However, due to the fact that the dosing device is not equipped with seed sowing sensors and a system that allows receiving information about the actual sowing rate and the operation of the entire device as a whole, in case of possible failures in the sowing process due to lack of information, the possibility of prompt response to deviations is excluded In the work, there is an increased consumption of seeds at the same time in the presence of long passes, which ultimately affects the decrease in yield.

There is also a known Niva-23 seeding monitoring system, containing a seeding sensor connected by cable cabling, a track sensor and a monitor with a display and a data processing unit (Niva-23 seeding monitoring system. Technical description and operating instructions, TU U 13947468.007 -98, LLC Poltava Engineering Group, Poltava, Ukraine).

The described construction is the closest in technical essence and the achieved positive result to the claimed utility model and is taken as a prototype.

This design is more perfect than the designs described above and allows you to control the accuracy of sowing seeds, receiving information about the rate and uniformity of sowing, speed and other technological indicators of the sowing unit. Possessing information about the characteristics of the sowing process, it became possible to influence their quality indicators. This system allows you to save seeds, improve the quality of sowing and increase productivity.

However, with certain advantages, this seeding control system has significant disadvantages:

- the system is equipped with a program that does not provide sufficient efficiency in the collection, accumulation and processing of data;

- the data processing unit has a low information sensitivity, the supply and change of current information occurs

at least every first and every 16 meters, which reduces the speed of obtaining and processing information, and therefore the response to any malfunction of the sowing unit, which affects the setup time (increases) and the efficiency of the system as a whole;

- the monitor display (liquid crystal indicator) has the greatest contrast when viewed from a direction perpendicular to its front surface, which is inconvenient to use because during operation, it becomes necessary to read information at different angles other than 90 °; in addition, this type of display is inconvenient to use due to increased storage requirements at low temperatures and low resistance to mechanical damage, which creates additional inconvenience in agricultural production;

- the system is equipped with a weak sound signal, which may not be heard during tractor operation.

Thus, the main disadvantages of the control system for sowing seeds, adopted as a prototype, are low operating conditions, inconvenience in operation, lack of reliability and efficiency.

The purpose of the proposed utility model is to improve operating conditions, increase the convenience, reliability and efficiency in the operation of the control system for sowing seeds.

This goal is achieved by the fact that in the control system for sowing seeds, which are connected by cable cabling and secured with special brackets on the seeder and tractor, seed sensors, a track sensor and a monitor with a display and a data processing unit, according to a utility model, the data processing unit is equipped with a fast processor and upgraded operating program, and the display is an LED matrix module.

In addition, special brackets for securing sensors and a monitor are equipped with gaskets that dampen vibration.

Providing a data processing unit with a high-speed microprocessor and an upgraded operating program can dramatically increase the efficiency of the seeding system. There is the possibility of obtaining and processing information, in fact, for each revolution of the seeder wheel, which in practice reduces the setup time and allows you to very quickly identify any malfunction and therefore quickly respond and eliminate it. Information sensitivity and information processing speed is significantly increased. Modernization of the program also allows optimizing the presentation of the necessary information for the user. The tractor driver, being in the tractor cabin, in time receives information about the rate of sowing seeds in each row, omissions and failures on a particular row, the uniformity of sowing seeds, the distribution of seeds in rows, the speed of movement, etc., which allows him to reliably control the accuracy of sowing seeds . Increasing the sensitivity and efficiency, convenient and optimally presented information significantly improves the operational characteristics of the system, its reliability and efficiency in work.

Placing information on the display, which is an LED matrix module allows you to conveniently read information from any angle, which is very convenient in operation. In addition, this type of display has a higher speed of visual perception, is less sensitive to mechanical damage and low temperature, which is also convenient during operation and storage.

The supply of special brackets for fixing the sensors and the monitor with vibration-damping gaskets increases the reliability of operation, as Excessive vibration of system elements can lead to premature failure.

In addition, the inventive system has an audio signal stronger than the audio signal of the prototype, which also increases the convenience in operation.

The set of essential features of the proposed utility model is unknown to the author from the level of existing technology, which allows us to conclude that the technical solution meets the criterion of "novelty."

The set of essential features of the claimed utility model can be repeatedly reproduced in industry and agriculture to achieve the goal of improving operating conditions, improving convenience, reliability and efficiency in work, which allows us to conclude that the technical solution meets the criterion of "industrial applicability".

The essence of the claimed utility model is illustrated by drawings, where: Fig. 1 shows a schematic diagram of the "Rhythm" sowing control system - a general view; figure 2 - shows a monitor display; figure 3 - diagram of the mounting of the monitor with special brackets and vibration damping pads.

The seed rhythm monitoring system "Rhythm" contains seed sowing sensors (1), a track sensor (2) and a monitor (3) with a display (4) and an information processing unit. The listed system elements are connected by cabling (5) and secured with special brackets (6) to the seeder and tractor. The data processing unit is equipped with a high-speed microprocessor and an upgraded operating program. Display (4) is an LED matrix module. On the front panel of the monitor (3) there are control buttons (7). Special brackets (6) are equipped with vibration damping pads (8). At the request of the customer, the control system for sowing seeds can be equipped with seed level sensors.

The control system for sowing seeds "Rhythm" as follows. Using special brackets (6) with vibration damping pads (8), the seed sowing sensors (1), the track sensor (2) are installed on the seeder and monitor elements (3) with a display (4) and a data processing unit in a convenient place in the cab tractor. Then all the elements

interconnected by cabling (5). The cabling is attached to the seeder elements using clamps, brackets or other known elements. After connecting the power connectors, the system is checked for function. The operating program allows automatic testing of the system with a check of the state of the sensors. If necessary, you can configure the system and enter additional parameters (or change them), data for calculation and task setting commands using the control buttons (7) of the monitor (3). Also, if necessary, the path (distance traveled) is calibrated to obtain actual data due to possible slippage of the seeder wheels. The preparations necessary and sufficient for reliable operation are completed and the system is ready for operation.

When the tractor begins to move, the drive wheels of the seeder rotate and the heads of the mounting bolts, passing with a predetermined clearance past the path sensor (2), transmit a signal to the microprocessor. In seeding sensors (1) (capacitive type), when seeds pass between the sensitive elements, a change in capacity occurs, a signal appears, which is also transmitted to the microprocessor of the data processing unit. Thus, the collection and accumulation of information begins, and then its processing in a high-speed microprocessor using an upgraded operating program. The reaction time to a change in a given seeding rate can be changed, as well as the path length of the measurement site. We have the opportunity to receive data for each revolution of the seeder wheel, but in practice, it is optimal to set the fixation after 3-4 turns. Depending on the type of culture, the quality of the prepared field and the seeds themselves, humidity and other conditions, new parameters can be entered into the program. The optimally constructed information necessary for controlling the sowing of seeds is fed to the display (4), made in the form of an LED matrix module, so it is visually convenient for the tractor driver to read it. The operating program allows you to fully control everything

technological cycle of sowing, any malfunctions in the process of work and, accordingly, a quick response to their elimination. In case of possible fatigue and weakening of visual perception, the system is equipped with a sound signal that will inform about the beginning of a malfunction, and looking at the display the tractor operator will immediately receive information in which row, for example, the passage of seeds goes. Thus, complete and accurate information about the progress and quality of sowing seeds, both for each row and for the field as a whole, allows you to quickly influence the sowing process. It becomes possible to determine the highest speed of movement, taking into account all parameters, while maintaining the given uniformity of seeding.

By the forces of the author and a number of interested organizations, a prototype “Rhythm” seed sowing control system was manufactured and tested in operation. Tests have shown that the system monitors deviations from the recommended speed and provides information about it in the form of light and sound alarms, which positively affects such a parameter as the uniformity of seed sowing.

Thus, the claimed control system for sowing seeds "Rhythm" provides improved operating conditions, increased convenience, reliability and efficiency in work.
