SI9800071A - Ear raiser clamping device - Google Patents

Abstract

The ear raiser clamping device features a two level adjustment of the notch of the mowing ridge (12), which is carried out by a locking part (5) that can be rotated with the help of a plug inserted in openings (3) and (4), which are on the sides of the handle (1). On the blocking part (5) there is a cut-out (6), which ends on the lower side by a staggered bed (8) and on the lower one with an even surface (9) for the pressure cylinder spring (7) which pushes the blocking part (5) down to the surface of the handle tooth (16). By turning the blocking part (5) from the open position, when it is possible to move the finger of the mowing ridge (12) to such a position, that the surfaces (14) and (18) meet on the surface (15) of the handle tooth (16), a two-level adjustment of the mowing ridge (12) can be provided. If the locking part (20) is inserted into the handle (1) and is turned in such a way that the surface (21) touches the surface (15) of the handle tooth (16), a single level adjustment of the finger (12) of the mowing ridge is provided to a level adjustment (19), having its intermediate level setting between the level setting (13) and (17). One of the main features of the holder (1) of the ear raiser clamping device is also that the holder has welded connecting legs (23) and (24) on the lower part of the handle and that welded barrier after installation of the clamping device to the flat fan of the wheat raiser is not visible, giving the complete assembly of the ear raiser clamping device a more attractive look.

Description

CLASS CLAMPING CLAMP

The object of the invention is a clamp hoist device located on a clam hopper. This clamping device consists of a holder in which a locking part is movably attached by means of a pin. The locking part can be rotated so that it can be inserted into the holder of the clamping device of the mowing ridge finger, or rotated to allow height adjustment of the mowing finger finger. The invention is provided in different solutions depending on the different height adjustments of the finger of the mowing ridge, the design of the holder, and the implementation of the locking part.

The invention belongs to the international patent classification in A 01 D 65/00 and additionally in A 01 D 55/00 and A 01 D 34/13.

A technical problem that is solved by the invention is such construction of the clamping device of the clamshell lift, which allows maximum smooth external contours of the holder and the locking part and does not have outward protruding parts, thus preventing any stopping and locking of the clay or similar cutting material during mowing. however, automatic uncontrolled opening of the locking part is prevented due to the impact of the cutting material. The invention also enables the slaughter lift to be a complete structural unit, thereby preventing the loss of any part of this device in practical use. The invention also enables rotation of the locking part to achieve the desired adjustment heights, which is much easier than the hitherto insertion of the spring as a locking element through the holes of the holder of the clamping device.

The solutions I have known so far are:

According to patent DE 2835505 C2, the retainer is attached to the flat profile of the clamshell lifter and has a thin steel wire for securing the arresting pin with the ear against failure, the other end of which is arrested in the hole in the retainer.

- 2 According to patent DE 2928871 C2, the holder is mounted on a flat profile, in the holder there is a thicker spring, one arm of which arrests the finger of the mowing ridge, and the other arm encircles the holder with its curved part to protect the spring against failure.

A common feature of all the solutions mentioned so far is the relatively unsafe arrest of the safety spring in the clamping device holder of the hoist lift, and the relatively technologically demanding production of the safety spring - tolerance and bending of the safety spring wire in several planes. Also, in these structural solutions, the problem of stopping the slime or the cutting material in the area of the holder of the clamping device or the spring of the holder due to outward projections arises. According to the invention, the problem is solved by means of a rotary or movable locking part located in the holder.

In the locking part there is a notch in which there is a pressure spring, which is resting on the upper side on the stud and on the lower side on a flat contact surface, thereby pushing the locking part down on the surface of the tooth of the holder located on the holder of the clamping device. The locking part may also be without a pressure spring and its cutout on the underside ends rounded.

For a system with two or more height adjustments, the locking part has two or more support surfaces, and for a system with a single height adjustment the locking part has only one support surface. Height arrest of prison work at different heights or. thus, the height arrest of the finger of the mowing ridge, respectively. open position dearetation is enabled by rotation or rotation. by lifting this part. The holder of the clamping device is designed to be provided with a welding barrier on the underside of the holder, or with a welding barrier on the upper side of the holder.

- 4 The clamping device of the clamshell lifting device for the two-height adjustment of the mowing finger finger forms a holder 1 in which, by means of a pin 2 inserted through the holes 3 and 4 located on the holder 1, a locking part 5 having a cutout 6 is movable, in which the pressure spring 7 is located. The cutout 6 ends with a pivoted pivot 8 on the upper side and a flat bearing surface 9 on the lower side, which serves for tensioning the spring springs 7. After mounting the locking part 5 in the holder 1, the pin 2 is riveted. against the failure so that a riveting head is formed at the end of the plug 2. The locking part 5 has a hole 11 on the upper side, in which a metal wire can be manually inserted before dearement, making it even easier to perform deareration.

The finger of the mowing ridge 12 is inserted into the holder 1 in the open position, and the position of the first height adjustment 13 is reached by rotating the locking part 5 so that the surface 14 of the locking part 5 rests on the surface 15 of the tooth of the holder 16 and the position of the second height adjustment 17 is reached. to rotate the backing portion 5 so that the surface 18 of the locking part 5 fits on the surface 15 of the tooth of the holder 16.

In the one-height clamping device of the clamshell lifting device, it is also possible to insert the mowing finger 12 into the holder 1 in the open position, and to achieve the height position 19 by rotating the locking portion 20 so that it attaches the surface 21 to the surface 15 of the tooth of the holder 16.

In a multi-height clamping device, it is also possible to insert the mowing finger 12 into the holder 1 in the open position by rotating the locking part so that the corresponding contact surface rests on the surface 15 of the tooth of the holder 16.

The contact arms 23 and 24 on the underside of the holder 1 connect the holder 1 to the welding barrier 22, wherein the tooth holder 16 has an extended portion of the contact arm 23. The holder may also be arranged such that the contact arms 27 and 28 on the upper side of the holder connect the holder 1 with a welding barrier 25, wherein the tooth of the holder 16 is made by means of a notch 26 on the underside of the holder. If the holder is cast as cast, it is free of the welding barrier.
