SU125423A1 - Universal device for installing stem drives in front of wheels of tilled tractors - Google Patents

Description

The designs of shrub lifters and fairings used in the care of cotton, botanicals for sugar beet and other crops are known.

However, all these devices have a special purpose and can not be used in the processing of other crops.

The proposed device for installing stem drivers in front of the front and rear wheels of tilled tractors, consisting of stem drivers with tips, immersed in soil during operation, a transverse bar for attaching stem drivers to the tractor case, a transverse shaft with a lever for controlling the front and rear stem drivers and a canopy. and adjustment is 5 universal. This allows it to be used in the processing and harvesting of tomatoes, cabbage, potatoes, eggplant, medicinal and ether-bearing plants, and other agricultural crops.

A special feature of the proposed device is the possibility of centralized control of all tractor stem drives, the presence of safety devices preventing the possibility of breakers of tractor stem wheels of the tractor and reliability of the selection of branches from the soil surface.

FIG. 1 shows a side view of the device; in fig. 2 - view from above.

The device consists of stem drivers / front wheels, stem drivers 2 rear wheels with tips 3 and 4, brackets 5 for hanging front stem drivers, bar 6 with fixed brackets 7 mounted on the rear stem drivers, engine number 125423-2 -

arms 8, pivotally connected to the fixed, shaft 9 with levers 10 connected by rods // and 12 with stem of the control lever 13, rigidly connected to the shaft. The springs 14 hold the movable arms in the working position. The beam 6 is attached to the crankcase of the tractor with the help of brackets 15 and 16. The front wheel drive rotates in the hinges 17, and the rear wheel rotates in harnesses 18; the movable arms may deviate, turning around the axes 19. Under the action of their own weight, the stem catchers are pressed to the ground so that the tips are immersed in the ground. To limit their depth, they are provided with reference planes. To limit the embedding of the front stem drivers, use the adjusting screw 20, to limit the rear burial, a special device, consisting of spring, of the spring 14, block 21, and cable pull 22. To compensate for changes in the distance between the shaft and stem drivers that occur when the tractor turns, The front stem driver includes springs 23.

Subject invention

Claims (3)

1. A universal device for installing stem growers in front of wheels of tilled tractors designed to protect plants, for example, tomatoes, cabbage, potatoes and other agricultural crops with mechanized care and cleaning, characterized in that, in order to provide centralized control of stem drives with the help of one lever, a transversely located shaft is applied, to which are mounted the tractor stem drivers, and to compensate for changes in the tractor’s changes when the tractor turns scarlet and anterior stem of the plunger in their gi included elastic springs. 2. The device according to claim 1, characterized in that, in order to protect the stem drivers from damage during the operation and immersion of the tractor wheels in the soil, there is provided for automatic removal of the rear stem drivers from the soil, which means that the bearing bracket of the stem driver is designed as a kinematic chain, one link of which is the stationary part of the bracket with the unit at the free end, the other link is attracted to the stationary part and the spring-supported movable part with the cable, thereby providing for Bracket placement together with stem picker in the vertical direction. 3. The device according to claim 1 and 2, characterized in that, in order to increase the reliability of selection of branches from the soil surface by stem collectors, they are provided with tips, the tip of which sinks into the soil during operation.
