Abstract

 A device for determining the visibility parameters of tractors and agricultural machines consists of a device for determining a control point of a seat, a basic adjustment pad with a circular bubble level, a vertical rack with a swivel bracket, a measuring head for angles, a recording device, a power cable, characterized in that the measurement of viewing angles is carried out using electronic goniometers-encoders, and for a fixed installation of the vertical position of the rack, the basic adjustment a platform that allows you to smoothly adjust it with the help of three adjusting screws along the circular mark of the bubble level.

Description

The invention relates to devices for determining the visibility parameters of tractors and agricultural machines.

The device can be used to measure viewing angles in horizontal and vertical planes through the windows of the tractor cabs and agricultural machines.

The purpose of the utility model is to improve the convenience of recording indicators of visibility parameters, to increase the accuracy and reliability of the recorded data.

A known device for determining visibility from the workplace FE 235 (to Develop devices for determining the effort on the controls and visibility from the workplace [Text]: report No. 11b-99 / KubNIITiM; head. Sholokhov V.F .; execution: Polyakov O. A., Goncharenko P.G. - Novokubansk, 1999. - 72 pp. No. GR 01.990.003524), the construction of which uses the mechanical principle of measuring angular quantities. Determination of viewing angles in the vertical and horizontal planes is carried out on a circular sector scale by rotating the pointer arrow around a vertical or horizontal axis. An arrow-pointer of angles and an all-round visibility scale are mounted on a vertical stand, the vertical position of which is achieved by moving it forward or backward until the pointed ends of two metal cylinders (plumb lines) coincide, one of which is suspended on a thread.

The disadvantages of the known device are: the complexity of the measurements, the need to mount the measuring head for measurements in different planes, the need to enter the data of angular values into the table manually, an outdated technical solution to the design of the device.

To improve the convenience of recording angular indicators of visibility parameters, to increase the accuracy and reliability of the recorded data, a device is proposed, a diagram of which is shown in figure 1.

The proposed device consists of a device for determining the CTS 1, the basic adjustment pad with a circular bubble level 2, a vertical rack with a swivel bracket 3, the measuring head of the corners 4, the recording device 5 and the power cable 6.

The device operates as follows. The device is mounted on the seat of an agricultural machine. After adjusting the horizontal position of the base platform, we proceed directly to the measurement of viewing angles. By rotating the corresponding knobs of the encoder gearboxes, we measure in the horizontal plane, and then in the vertical plane. Encoders form rectangular electrical signals that enter a recording device for digital processing. By pressing the appropriate keys, the viewing angle is measured in the corresponding zone and in the given plane. Angles are measured both clockwise and counterclockwise.

The angle in the corresponding zone and in the given plane is displayed and recorded in non-volatile memory.

The obtained measurement data can be viewed on the display screen and transferred to the memory of a personal computer for further processing.

The advantages of the proposed utility model are to improve the convenience of recording indicators of visibility parameters, increasing the accuracy and reliability of the recorded data.
