    The invention relates to a chain feeder drive for a regular corn harvesting machine used mainly for harvesting large crops such as corn and sunflower from several rows in a single working stroke.
    Drive chain feeders are known for single row and multi core corn harvesting machines, in which the feed chains are driven using a shaft located across to the feed direction of the shaft, driven by a V-belt transmission, chain drive or gearbox. The individual supply chains from this shaft are driven through an open bevel gear. The drive shaft rotates in the twin bearing located on the frame, and has a drive sprocket on the upper end.
    The drive shaft can be moved axially to set the gap between the teeth of the bevel gears. In corn-harvesting machines with three or more feeding channels, the latter are displaced in height, so that the working grippers of the feeding chains at the transition point partially overlap each other. As a result of this, the transition to field powering bodies is not as wide as that of the supply chains, which are
    I in the same plane. However, a higher inclination of the driving shafts of the bevel gear transmission is required for the higher supply chains, since the 5 S is the receiving point for the harvested crop in front of the corn harvesting machine. Supply chains must be located at the same height. This requirement of different directions of the output part
    -l can only answer bevel gear; .;
    The disadvantage of the device is that the width of the junction of the discharge opening of multi-spread corn-harvesting machines with feed channels displaced in height and without them becomes so large that the chopper feed device is likely to be made wider than that required for
    0 given bandwidth. In addition, the placement of the wide feed device in field shredders of a self-propelled type is associated with many disadvantages
    5 due to the location of the supply chains
    on one straight line in front of the powering device, since the drive: is carried out from the shaft, is located across the junction of the power supply device. .
    0 Known drives of chain feeders through a bevel gear, which prevent these disadvantages, well, of which the middle supply chains end farther from the feeding device than the external ones, for which an additional shaft is needed. With a shift in height of the supply channels, the width at the point of transition to the supply device can be increased only by means of greater construction and material costs for the supply channels and a large amount of installation work with the drive means. The use of individual bevel gears for each supply chain has the disadvantage that only conical wheels that are relatively labor-consuming to manufacture can be used. In addition, a large number of bevel wheels and a large laboriousness of mutual adjustment of individual bevel gears and pitakhd chains are necessary. Another disadvantage is the short service life of such drives, since I have an open structure and are located in places of heavy contamination. The purpose of the invention is to create a chain-fed feeder for a row corn-harvesting machine with a large working grip, which, having a small joint width at the feeding device of the adjoining field shredder, a simple design and small material intensity, provided. Easy installation and long service life. The basis of the invention is when the chain feeder water is of a closed design, in which the drive sprockets are arranged as necessary to ensure a minimum joint width, and for which a small number of transmission wheels and drive elements are required, provided that a large number of identical parts are used. This goal is achieved by the fact that the drive of the chain feeder is carried out through a multi-stage cylindrical gear transmission, with the transmission shafts at the top protruding from it and equipped with driving sprockets for the supply chains. The shafts of the transfer shaft are located in such a way that, counting from the middle shafts, adjacent to them on both sides and each next cylindrical pair with respect to the previous one, are displaced in the feed direction of the harvested crop. As a result of this, the external supply chains terminate directly at the next field feed grinder next, as well. the average is most distant from it. This arrangement is also decisive for the selection of the outer shapes of the gearbox j-body. The spur gear drive is driven by Goat of one of the two cylindrical pairs located FRIENDLY through the drive unit when its spur gear engages with the corresponding spur gear. The drive of the drive unit is produced by means of known rotating drive elements, such as an articulated shaft, hydraulic motor, gearbox, chain drive, etc. The cylindrical gear train has a housing carrying all the drive mechanisms of the supply chains; However, the drive from the cylinder 1 gear can be made AND directly to one of the transmission shafts. It does not matter which transmission shaft is driven. It is advisable to place the drive below, because otherwise it may interfere with the flow of the crop to be harvested. The drive of the multistage cylindrical gear drive shafts from the drive unit occurs in such a way that the adjacent gear shafts rotate in the opposite direction, and (drive sprockets located on the top of the shafts drive the supply chains in the feed direction. By using one-way transport channels, t. i. that the supply chain is only on one side of the transport channel, ensuring the supply of the culture to be harvested, two transport channels located next to each other At the transition point, ala can end up in one transport channel. This is achieved by the fact that the supply chains in both transport channels are opposite each other, so that, in the opposite direction of the rotation of the transmission shaft, they run off at the joint transition point, as a result of which For harvesting corn from the outer sides of the transition point, four rows can be transmitted at the shortest distance to the feeding device of the shredder. The ends of the two middle rows of the crop being harvested at the transition point are captured by the stalks of the outer four rows, so that over all of these rows there is an additional feeding effect, i.e. a noticeable negative effect of rearranging the ptyge chains away from capture. . It is advisable to choose inter-axial distances of cylindrical pairs as odium-sized in size or gradually reduce from the middle to the outside. The same center distance provides the same capture rate of the supply chains, and a gradual decrease in the center distance leads to an increase in the capture rate of the external supply chains. Increased capture speed should be used when at very | wide harvesting machines, the reception of the stems of the harvested crop from the outside deteriorates. : It is advisable to design the cylindrical cogs of the gear unit so that the drive units of the supply chains, consisting of the transmission shaft with the bearing housing support and the drive sprocket at the top of the drive shaft, and the sprocket gear at the bottom, are mounted on a rigid case and have a detachable connection . The bodies of the bushings are equipped with a round flange, the sizes of which correspond to the diameter of the pitch circle of the corresponding cylindrical gear, and the flanges of the adjacent bearing bodies lie adjacent to each other without clearance. This design allows for quick installation of individual drives of the supply chains on the case, while observing the required coupling ratios. Another design variant is that the body consists of located, on; the distances from each other and the bodies and lids of the transmission carrying shafts with the support, spur gears and driving sprockets connected by the shaped steel. At the top of the ramp above the cover of the shafts in one of the pits there are leading sprockets of the supply chains. The transmission shafts extending beyond the base plate carry cylindrical gears meshed with adjacent cylindrical gears. The oil in the bath overlaps the entire spur gear. Such a variant of transmission using each shaft as drive for power chains can be further modified by the fact that intermediate gears are included between the drive shafts. Due to this, smaller gears can be used, which is advantageous in the dimensions of the spur gear. In addition, by varying the number of intermediate gears and the corresponding location of the supply chains on the left or right in the transport channel, it is possible to provide a drive for the chain feeder of corn harvesting machines when harvesting any number of rows. Another change in the drive supply chains is also possible by replacing the cylindrical pairs of chain transmissions. The advantages of the proposed drive of the drinking chains are that the arrangement of the transmission shafts provides a small width of the junction of multi-range corn harvesting machines. Compared to bevel gears, gears are reduced by half the number of gears, and the cylindrical gears are less complicated to make than bevel gears. Compact .mjH construction in the form of a cylindrical gear. transmissions — eliminates the time-consuming setup required to install the appropriate gear stages and the drives of the individual supply chains when using separate bevel gears. In addition, a cylindrical gear assembly is assembled from a much smaller number of individual parts than a drive consisting of several bevel gears, which has a positive effect on both the production of gears and the provision of spare parts. The installation of spur gears is also accelerated. The structure is closed. drive supply chains. provides a longer service life. FIG. Figure 1 shows a six-sided bottom of a corn-harvesting machine with a cylindrical gear drive as a drive for supply chains, top view; in fig. 2 — cylindrical gear transmission over the external supply channel and drive unit, section; in fig. 3 is a cylindrical gear of a six-sided corn harvesting machine, top view. The corn harvesting machine 1 has six feeding channels 2, which are arranged in accordance with the width between the rows of the crop being harvested. The supply circuits 3 are made in the form of one side-side supply circuit, that is, in one supply channel 2 there is a supply circuit 3 on one side only, At the same time, two supply chains 3 work together in the transition to the power supply unit 4 of the field grinder, What is achieved by the opposite arrangement of the supply chains 3 in the supply channel 2. Thus, two external and both middle supply channels 2 respectively work together. The supply chains 3 terminate in front of the transition point to the feeding device 4 of the field grinder. m a way that, starting from the medium supply circuits 3 adjacent to them on both sides and each A further towards predschuschey shifted .napravlenii supplying retractable cult
    ry As a result, the outer supply chains 3 end at the shortest distance from the feeding unit 4, and the middle supply chains 3 are located at the greatest distance from it. The drive sprockets 5 of the feeding chains 3 are fixed on the console sections of the upstream shafts 6, fitted on the lower end of the cylindrical gear 7. The cylindrical justers 7 form, in accordance with the arrangement of the shafts 6, gears which are meshed and arranged in a row of cylindrical pairs arranged in cylindrical gear 8.
