Description

In devices for transferring arrows from a moving slurry, it is known to make vertically movable with sharpening points, set in a desired position to be lowered from the cart with a yoke attached to a slider tooth associated with sharps. In the proposed device, the tooth, which is picked up from the cart by the bracket, is pivotably mounted on the slider and is equipped with a tail resting against a spring latch that automatically releases it to release the tooth from the bracket after the poles are moved to a new position. To return the tooth, after uncoupling with the bracket, to its original position, it is provided with a retracting spring.

In the schematic drawing of FIG. 1 shows a vertical longitudinal section of the mechanism; FIG. 2-vi slider on top; FIG. 3 is a top view of the mechanism with the slider removed; FIG. 4 - cross-vertical section of the mechanism; FIG. 5-part locking device; FIG. 6 is a side view of the moving part; FIG. 7 - view of the arrow in the plan; FIG. 8 and 9 - details of the pedal.

The mechanism for transferring the arrows is placed in a T-shaped cast-iron box 37 with a tightly closed lid. In the longitudinal part of the box are placed: a slider 2, equipped with a swivel tooth 7 with a tail and a finger 23, connected by a spring or rubber 24 with a fixed pin 25, eighteen rollers 3 (nine on each side) along which the slider 2 moves, one block 4 and two blocks 3-5, coil spring 6, connecting cable 7 and latch 77 in the form of a spring loaded J9 with a swivel pin J8. In the transverse part of the box, there are: a crankshaft vertical shaft 8, two movable ones connected with the knee 8, ti L - 77, having slots 29 to 30 and through the bolts 28 transmitting the movement of the movable parts 75, 74, 15 and 35 arrows 16. (Fig. 4, 6 and 7), wooden pulley 9, freely rotating on the shaft 8 and equipped with two TO-70 pawls, then two sliders 13-13 moving along the guides 12-12 with movable parts 14-14 sharp the arrows 76 and swiftly in pairs of rollers 75-75, and, moreover, on the front sections of the sliders 13 there are also cranked levers 27. Finding the same a carriage portion of the mechanism (Fig. 8)

consists of a rod 41 passing through the floor with a fork in an ideal plug 46 with eyelets 47 pivotally connected to a clip 51 pivotally connected at its ends 48 to a vehicle safety net equipped with stops 49 SO. The rod 41 is wound with a fork and provided with a spring 45 abutting against a sleeve 43 fixed on the pins 44 in the second sleeve 42 inserted into the floor of the vehicle.

To move the driver's driver, approach her, presses her foot on the head of the rod 41, and as she moves

the bracket 57 passes (Fig. 1) through the protective ridge 22, protecting the tooth 7 from impacts of the wheels of the passing vehicle and engages with the tooth 7 of the slide 2 arrows. The tooth 7, moved by the yoke 51 forward, carries along the slider 2, which rolls along the rollers 3 and t is not attached to the rear cable 7, enveloping the blocks 4 to 5 and

Passing on the pulley 9, at point 26 of which it is fixed; its end passes further through the second block 5 onto the connection with the spring 6. As a result, as the slide 3 moves to the right (Figs. 1 and 3), the pulley 9 turns in the opposite direction of the clockwise rotation by approximately 183 ° and the spring 6 is pulled . Together with the pulley 9, the ratchet paws W are turned until one of them rests against the protrusion 34 on the knee of the shaft S, the drive of the latter into rotation, and the 7 7-77-motion connected with it. When moving t g 11-11 to the right, the left wall of the slot 29 in the left t ge 7 T approaches the bolt 28, and at the same. At the same time, the left side of the slot 30 presses on the upper arm of the crank arm 27, and when this shoulder is pressed onto the right oblique wall of the slot 30, the lower shoulder presses down the latch 32 supported by the spring 33, which allows the slider to further advance 13, and with it the moving part of the arrow. At the same time, the rollers 75-75 (both on the left and right sides of the box) retract to the right (Fig. 4), as a result of which the moving parts 7 of the edges on the left side descend and on the right move up until the right slider 13 with the crank lever 27 does not release the latch 32, which under the action of the spring 33 closes the slider 13. At the same time, the slider 2 (Fig. 1) advances to the right and when it approaches its extreme position, the pivot pin 18 on the latch 77 squeezes the spring 7 will come out from under the tail protrusion 1a of tooth 7 and unlocks the latch, and tooth 7, rubbed into the support, turned a right, releasing this bracket 57. Then, under the action of the spring / j tooth J vernets in initial notched, and the slider 2 by the compression spring 6 receives the reverse motion and also returns to its original location, preparing the arrow to the next transfer.

When the carriage is moving against the arrow of the arrow, if it is necessary to keep the sweeping movement, an additional rectangular box is installed in front of the T-shaped main box, in which a slider is placed on rollers, similar to slider 2. Being connected by a cable with the front part of slider 2 in the main box, the latter, which is grasped from the wagon over its tooth with a yoke, does not have a slider 2 behind it, and the transfer of the arrow takes place as stated above. If the movement of the cart occurs only against the wool of the arrows, the entire installation of the main box is done in the opposite direction.

The subject matter of the invention.

Claims (3)

1. A device for translating arrows from moving carriages, including a slide connected with the translation mechanism, moved through the bracket, which is attached to the slide tooth and disengaged from the slide after moving the points, which is different in that the tooth G is installed on the slider 2, it is rotatable and provided with a tail 7a, designed to rest against the latch 77, which automatically releases it, with the purpose of uncoupling the tooth from the brace after transferring the points to a new position (Fig. 1 and 3). 2. The form of the device according to claim 1, characterized in that the latch 77 is made in the form of a spring-loaded slider with a pivot pin J8, which moves the latch to the unlocking position when it stops at the fixed pin 25 (Fig. 1). 3. When making a device according to claim 1 and 2, use the spring 24 coupled with the finger 23 of the rotary tooth 7 and intended to return it to its original position after uncoupling the clip (Fig. 1).
