Abstract

FIELD: agricultural engineering.

SUBSTANCE: invention relates to devices for clamping nozzle bodies on flexible hoses for various placement on a field sprayer boom. The clamp consists of upper (3) and lower (4) clamps, on the front ends of which there are grooves directed towards and along the profile (2) of the rod. Assembled clamps cover the profile (2) of the sprayer boom and the nozzle body (1). At the opposite end of the lower clamp (4), a threaded hole for the connecting bolt (7) is made, and on the upper (3) clamp, in the area of the threaded hole, a connecting groove is made. The upper (3) clamp is made in the form of a flat plate with a bend of 4-6 degrees on the attachment side of the nozzle body (1). The lower clamp (4) is -shaped. The bend line of the upper clamp (3) coincides with the bend line of the bent end of the lower clamp (4). The groove for installing the nozzle body and the connecting groove of the upper clamp are made longitudinally.

EFFECT: improved clamping efficiency and reliability for use with flexible hose nozzle bodies.

Description

The invention relates to agricultural engineering, in particular, to clamping devices for nozzle bodies on flexible hoses for various placement on a field sprayer boom.

Known clamp-type nozzle holder for the introduction of HCS and SZR for wet boom field sprayers [Teejet tehnologies Catalog 51A-RU, page 59].

The disadvantage of this type of connection is the impossibility of changing the distance between the sprayer housings when the sprayer distributes the working solution in a band.

Also known is a nozzle holder for rods with a hose, which can be fixed to the rod with a bolt with a nut Mb, which is inserted into a special socket in the upper part, and the bolt passes through a hole in the upper part of the profile of the U-shaped rod

The disadvantage of this type of connection is that it requires a lot of holes in the rod to smoothly change the distance between the sprayer housings with an adjustable band distribution of the sprayer's working solution.

The closest technical solution is a clamp for use with nozzle bodies for flexible hoses, consisting of two U-reverse clamps with ends bent in opposite directions, on one side of the clamps on the bent ends, mirror-symmetrical grooves are made along the plane of the rod attachment forming a closed profile, during assembly of the clamps corresponding to the place of the attachment body of the nozzle, and on the opposite bent ends, on the lower clamp, a threaded hole for the connecting bolt is made, and on the upper clamp in the area of the threaded hole, a connecting groove is made, coinciding with the direction of the groove of the opposite end [Teejet technologies Catalog 51A-RU, p. 56].

The disadvantages of the clamp include the complexity of manufacturing the clamp profile and low reliability due to the complicated procedure for installing the clamp on the sprayer boom.

The task is to simplify the manufacture of the clamp for use with nozzle bodies for flexible hoses, to increase the reliability of the clamp fastening and the convenience of its installation.

EFFECT: increased efficiency and reliability of the clamp for use with nozzle bodies for flexible hoses.

The technical result is achieved by a clamp for use with nozzle bodies for flexible hoses, consisting of upper and lower clamps, on the front ends of which there are grooves directed towards and along the profile of the rod, the assembled clamps cover the profile of the sprayer boom and the nozzle body, at the opposite end of the lower clamp, a threaded hole for the connecting bolt is made, and on the upper clamp, in the area of the threaded hole, a connecting groove is made, while the upper clamp is made in the form of a flat plate with a bend of 4-6 degrees on the attachment side of the nozzle body, the lower clamp is made -shaped, and the bend line of the upper clamp coincides with the bend line of the bent end of the lower clamp, in addition, the groove for installing the nozzle body and the connecting groove of the upper clamp are made longitudinally.

In FIG. 1 shows a clamp for use with flexible hose nozzle bodies, side view with the nozzle body installed; fig. 2 - the same, with the nozzle body installed and fasteners tightened; fig. 3 - clamp for use with nozzle bodies for flexible hoses, type A; fig. 4 - clamp for use with nozzle bodies for flexible hoses, view B.

Clamp for use with nozzle bodies for flexible hoses is designed to fasten the nozzle body 1 along the profile 2 of the sprayer boom with the ability to move along the profile 2. The clamp consists of top 3 and bottom 4 clamps. Bottom 4 clamp has - shaped with curved ends. Landing dimensions -shaped shape correspond to profile 2. At one end of the lower clamp 4, a groove 5 is made parallel to the plane of bends -shaped form. The width of the groove 5 corresponds to the size of the attachment point of the nozzle body 1. In turn, at the opposite end of the clamp, a threaded hole 6 is made for the connecting bolt 7. The upper clamp 3 is made by a flat plate with a bend of 4-6 degrees. The bend line 8 of the upper 3 clamp coincides with the bend line 9 of the bent end of the lower 4 clamp, from the attachment side of the nozzle body 1. The width of the groove 10 corresponds to the size of the attachment point of the nozzle body 1. At the opposite end of the top 3 clamp, a connecting groove 11 is made with the width of the diameter of the connecting bolt 7 Groove 10 for installing the nozzle body and groove 11 connecting the upper clamp are made longitudinally.

The proposed clamp device for use with flexible hose nozzle bodies works as follows. To fasten nozzle body 1 along profile 2 on the sprayer boom with the ability to move along profile 2, nozzle body 1 is installed in groove 5 of the lower 4 clamp. -shaped profile and is fixed with the upper 3 clamp, inserting the groove 10 into the attachment point of the nozzle body 1 forming a closed profile. Further, through the groove 11, the bolt 7 is inserted into the threaded hole 6. By tightening the bolt 7, the upper 3 and lower 4 clamps are tightened. When tightening the upper 3 and lower 4 clamps, through the bending of the fold line 8, the ends of the grooves 10 and 5 will be unclenched, fixing and orienting the body of the nozzle 1 along the profile 2 of the rod. When assembled, the clamp secures the body of the nozzle 1 and covers the placement profile in the required place on the sprayer boom with the possibility of adjusting the location when the tightening bolt 7 is loosened.

Thus, the claimed design of the clamp for use with nozzle bodies for flexible hoses provides the claimed technical result: - improving the efficiency and reliability of the clamp for use with nozzle bodies for flexible hoses.
