SU119385A1 - Measurement adaptation to caterpillar tractors for sowing row crops in various ways without measuring wire - Google Patents

Description

The known measuring devices intended for square-nesting sowing without measuring wire do not provide accurate seeding squares, since either the tractor's power take-off shaft or the driving wheels are used as sources of movement without taking into account the correction of errors in the spacing between the holes and between the angles as a result of skidding and sliding tracks and wheels.

The proposed measuring device for tracked tractors does not have this drawback and ensures the correctness of sowing within the width of the grip of the gun without measuring wire and marking with any step. This is achieved by the combined use of interconnected balancing and correcting differentials, a worm gear and an endless chain, the special links of which can be installed on any schag.

The drawing shows the arrangement.

The device consists of a housing /, equalizing differential 2 with semiaxes 3 VI 4, correcting differential 5 with a hollow shaft 6 VI shaft 7, a reversing mechanism 8, a worm gear pair 9 and 10 with a shaft 11, a conical pair} 2 and 13 with a shaft 14 and stars 15 and 16.

The equalizing differential equalizes the rotation of axes 3 and 4. The axles receive rotation from the right and left final gears of the tractor. The equalizing differential 2 transfers the resulting rotation to the correcting differential 5. The bevel gear 17 of the correcting differential is rigidly connected to the worm gear 9 by means of a hollow shaft 6.

When sowing, the correction mechanism is not used and the conical brush 17 does not rotate. Therefore, the conical scabies 18 rotates at double speed, and the correction differential in this case plays the role of a reducer that doubles the rotation. The number of teeth on the crowns of differentials 2 to 5 is the same.

Shaft 7, which is rigidly connected to rivet 18, transmits rotation to drive shaft 14 by means of a conic pair 12 and 13 and to sprockets 15 and 16, which transmit motion to the pointing circuit and, if necessary, to the driving circuit. The chains can be located both on the left side of the tractor, and on the right (the chains are not shown in the drawing).

Lo 119385-2 -

The reversing mechanism 8 consists of two figured gears 19 and: 20, which with the help of a small bevel gear 21, rotate in opposite directions. Dumping is transmitted from the tractor's take-off shaft, via the shaft 22 and the gear 19 rigidly connected to it.

Double cone clutch 23; on the splined part of the shaft 11 and with the help of the lever 24, it can be pressed against the tapered surface of the shaped gear 19 and 20, as a result of which it receives right or left rotation. The rotation obtained by the clutch is transmitted through the shaft 11 of the worm pair 9 and 10. As a result, a deceleration or acceleration of the rotation of the gear 18 of the correcting differential is achieved.

The reverser is a loose device only for adjustments.

The gear ratios in the gear transmission are adjusted so that the circumferential speed on the sprockets 15 and 16 rbH is the translational speed of the tractor.

The proposed fixture allows to produce with the necessary pitch without the use of measuring wire. The specified spike is achieved at the post office installation of the inferior chain of special links at the required distance from each other. In this case, the length of the drive chain should be a multiple of the seed.

During the period of weeding and dressing, the device actuates the active organs (paws) of the cultivator, which processes the sowing in one pass in rows and between the rows.

When processing, the device allows, as necessary, to make adjustments to the accuracy of the active organs of the keltivator due to the mechanical energy of the engine. The adjustment is made by the operator.

The device allows work to be performed on different gears of the tractor, which switching does not affect the synchronism of the action of the aggregated machines and implements.

During crop care, the fixture allows fertilizing by fertilizing with nests at the desired distance from the plants.
