Abstract

Caterpillar trolley containing a welded frame, drive gear, gearbox, endless caterpillar belt, tension mechanism, characterized in that a lever-balancer suspension with elastic elements is introduced into it, while the lever-balancer suspension consists of four independent levers on which it is articulated carriages with four rollers are installed, each lever is pivotally mounted on the carriage frame on one side, and on the other hand through elastic elements, each carriage being attached to the frame using two elastic elements.

Description

The inventive utility model relates to agricultural engineering, in particular, to the basic structural elements intended for installation on agricultural machines, to ensure a steady flow of the technological process of harvesting when working in difficult soil conditions (in poor terrain).

There are known designs of crawler (crawler) trolleys developed by Birobidzhan Combine Plant Dalselmash CJSC (www.avtomash.ru/pred/dalselmash/dal_istori.htm), OJSC PA Krasnoyarsk Combine Plant (www.kzk.ru), PO “Gomselmash” (www.gomselmash.by) [1-6].

The crawler track of the known devices consists of a trolley with an endless (closed) caterpillar belt mounted on it. Copying the topography of the soil and smoothness are provided by two independent support carriages, which have a spring consisting of two coil springs. The support carriages consist of four to five road wheels, which are rigidly attached to the carriage. Track rollers of each side on the carriage frame are rigidly combined into the front five-car and rear four-car carriages. In turn, each carriage is pivotally connected to the frame of the tracked trolley, and also connected to the frame through elastic elements.

The disadvantages of the known devices are: a) the rigid combination of track rollers on the carriage frame, which does not allow the rollers to move relative to each other and copy the soil profile when hitting an obstacle, while the rigid connection creates significant loads on the track rollers; b) large vibrations of the combine, increased load on the rollers and pressure on the soil when moving a single surface roughness.

The closest analogue of the claimed utility model is a caterpillar truck used in the design of the PALESSE GS812C combine harvester developed and manufactured by Gomselmash software (www.gomselmash.by) [7]. The disadvantages of the prototype indicated above.

The objective of the claimed utility model is to reduce the load on the rollers due to its more uniform distribution over the entire surface of the caterpillar, reducing the amplitude of the vertical vibrations of the combine and the longitudinal angular vibrations of its skeleton when moving along irregularities to ensure its more stable position during the course of the harvesting process.

The technical result is achieved by the fact that in the caterpillar carriage containing a welded frame, a drive gear (sprocket), a gearbox, an endless caterpillar belt, a tension mechanism, a lever-balancer suspension with elastic elements is introduced. The lever-balancer suspension is four independent levers on which carriages with four rollers are pivotally mounted. Each lever is fixed on the trolley frame on the one hand pivotally, and on the other hand through elastic elements, each carriage being attached to the frame using two elastic elements. Such a suspension allows you to copy the relief, providing increased smoothness, while it provides a reduction in the load on the cart elements, their vibration level, as well as a decrease in the amplitude of the vertical movements of the combine when driving on bumps.

The utility model is illustrated by drawings:

figure 1 - tracked truck, General view;

figure 2 - tracked cart, side view;

figure 3 - lever-balancing suspension.

The caterpillar trolley (figure 1, 2) includes the following elements: 1 - the frame of the caterpillar trolley; 2 - slider; 3 - gear; 4 - a driving wheel (asterisk); 5 - rubber-reinforced caterpillar track; 6 - a directing (tension) wheel; 7 - depreciation-tensioning device; 8-supporting roller; 9 - lever-balancing suspension; 10 - track roller; 11 - a block of elastic elements; 12 - carriage; 13 - carriage lever.

The device operates as follows. During the movement of the harvester along irregularities, the carriage 12, due to the articulation with the lever of the carriage 13, rolls over the unevenness. Part of the load due to uneven movement is transmitted to the carriage lever 13 with elastic elements 11, which absorb the load and vibrations on the frame of the tracked cart. Thus, each pair of rollers 10 copies the irregularity regardless of the operation of the other suspension elements, thereby ensuring constant contact of each roller with the soil and evenly distributing the load over the entire surface of the track 5.

The design of the claimed utility model reduces the load on the rollers, distributing it over the entire surface of the track, reduces the vertical vibrations of the combine and the longitudinal angular vibrations of its skeleton when moving along bumps, providing a more stable position during the process of harvesting, increasing the reliability of the combine, reducing pressure on soil and improved operator comfort during operation.
