Description

A cotton picker spindle seat tube measuring device

Technical Field

The invention belongs to the field of cotton harvesting machinery maintenance, and in particular relates to a cotton picker spindle seat tube measuring device.

Background technique

The spindle picking seat tube is an important carrier for realizing the picking function of the cotton harvesting equipment and is an indispensable component of the cotton harvesting equipment. The manufacturing and assembly accuracy of the spindle picking seat tube directly affects the factory qualified rate and the clean picking rate of the cotton harvesting equipment. As is known, as shown in FIG1 , the conventional structure of the spindle picking seat tube of the cotton picker includes a rotating arm shaft head 01, a rotating arm 02, a rotating support sleeve 03, a seat tube 04 and a picking spindle 05. One end of the rotating arm 02 is sleeved with a rotating support sleeve 03, and the other end of the seat tube 04 is provided with a supporting blind hole. Usually, after a continuous harvesting operation of a cotton harvesting equipment in a harvesting season, the spindle picking seat tube is subjected to the action of alternating loads during the harvesting process, and the rotating arm 02 and the seat tube 04 are deformed. The distance between the axis of the rotating arm shaft head 01 and the rotation center of the rotating arm 02 (i.e., the center distance of the rotating arm) changes, resulting in the swing of the spindle picking seat tube, the change in the spacing size of the picking spindle 05, and the increase in the driving load, which directly affects the clean picking rate of the equipment.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

A displacement measuring assembly is installed on the base 2. The displacement measuring assembly includes a plurality of displacement measuring rods 19 capable of synchronous extension and contraction adjustment. The displacement measuring assembly can also adjust the height and inclination angle of the displacement measuring rods 19. The displacement measuring assembly uses a plurality of displacement measuring rods 19 to correspond to the picking spindles 05 one by one to measure the displacement of the picking spindles 05.

The swing arm center distance measuring component is used to measure the distance between the axis of the swing arm shaft head 01 and the rotation center of the swing arm 02, and the swing arm center distance measuring component measures the swing arm center distance by fixing the end of the seat tube 04 and the swing arm shaft head 01 at the same time.

In the embodiment of the present invention, an adjustable distance support component is defined, which can stably support the seat tube 04 for rotation and can adapt to stable support of seat tubes 04 of different lengths; through the definition of the deformation measurement component, the displacement measurement component and the swing arm center distance measurement component, the seat tube 04 deformation measurement, spindle 05 displacement measurement and swing arm center distance measurement functions of the cotton picker spindle picking seat tube are integrated, and it is possible to detect whether the various dimensions of the spindle picking seat tube are appropriate, so as to promptly inspect and maintain the unqualified spindle picking seat tube, thereby making the cotton picker work stably and efficiently.

A motor 1 transmission-connected to the screw rod 7 is also fixed on one of the end seats 3.

In addition, a scale (not shown) can be set on the deformation measuring rod 17, so that the deformation can be measured by adjusting the deformation measuring rod 17 at the deformation location to read the value.

Then, by measuring the change in the scale (not shown) on the telescopic rod 34, the distance between the axis of the swivel arm shaft head 01 and the rotation center of the swivel arm 02 can be measured, that is, the center distance of the swivel arm is measured.

The above embodiment of the present invention provides a cotton picker spindle seat tube measuring device, which defines an adjustable distance support assembly, can stably support the seat tube 04 for rotation, and can adapt to stable support of seat tubes 04 of different lengths, specifically:

Through the definition of deformation measurement components, displacement measurement components and arm center distance measurement components, the seat tube 04 deformation measurement, spindle 05 displacement measurement and arm center distance measurement functions of the cotton picker spindle seat tube are integrated, which can detect whether the various dimensions of the spindle seat tube are appropriate, so as to timely repair and maintain the unqualified spindle seat tube, so as to make the cotton picker work stably and efficiently. Specifically:

By setting the deformation measuring rod 17 to be able to perform horizontal and vertical adjustment and to be able to move along the guide edge 6, the surface deformation of the seat tube 04 can be measured, that is, by fixing the position of the deformation measuring rod 17, sliding close to the surface of the seat tube 04, when the sliding is hindered, it indicates that the seat tube 04 is deformed, and the seat tube 04 is rotated, so that the deformation measuring rod 17 can perform a comprehensive measurement of the surface of the seat tube 04.

The telescopic cylinder 13 and the arc-shaped telescopic cylinder 23 can be used to conveniently adjust the displacement measuring rod 19 to accurately correspond to the picking spindle 05 after rotating to a certain angle, thereby improving the adaptability of the measurement; by adjusting the expansion and contraction of multiple displacement measuring rods 19, the displacement measuring rod 19 is adjusted to correspond to the standard spacing between the picking spindles 05, and the measurement needs of the picking spindle seat tubes of different models of cotton pickers are adapted, which is convenient and quick.

The telescopic rod 35 is adjusted to meet the changing needs of the distance between the swivel arm shaft head 01 and the end of the seat tube 04 of different types of spindle picking seat tubes, and then locked by fixing bolt three 36. The air pump 11 can be controlled to extend the cylinder 1 28 and the cylinder 2 32 at the same time, and abut and fix them through the circumferentially distributed clamp plate 1 29 and clamp plate 2 33. Since the air pressure of the pneumatic fixation is consistent, the center accuracy of the fixation is high and the fixation efficiency is high. Then, by measuring the scale change on the telescopic rod 34, the distance between the axis of the swivel arm shaft head 01 and the rotation center of the swivel arm 02 can be measured, that is, the center distance of the swivel arm can be measured.
