Description

The utility model relates to a plate rake for garbage collection.

The problem of modern manufacture of tools such as rakes is that such rakes can be produced by stamping as a single integral part only on complex production equipment using industrial presses. This complicates the tool manufacturing process and limits the possibilities for mass production.

Known broom rake (patent RU68836U, publ.: 10.12.2007), containing a head made of fan-shaped working elements, means for connecting the handle to the head - holder, characterized in that the working elements are rods-teeth, length from 250 to 350 mm are made curved on one side, and with a distance from the bend from 30 to 70 mm, on the other hand, a groove or a hole-groove is made, and the holder has an insert that can be equipped with fastening means to hold additional rake elements, the retention function p Of the other elements in the holder, a nail passes through the groove or grooves of the working elements, fixed in the holes of the holder, and also provided with a comb, which can be made in the form of a straight bar, or in the form of an arc, and can also be equipped with ribs stiffness and optionally can be equipped with a holder.

The decision was made as a prototype.

Such a rake can be produced in a makeshift way on a small bending machine.

But this broom rake is technically difficult to manufacture, because it uses a lot of technological operations to install the plates to form a fan, spread them at the right angle and maintain a given distance. In addition, many bending operations are required to clamp the fan.

The objective of the utility model is to eliminate the disadvantages of the known plate rake.

The technical result is the possibility of manufacturing a rake design in a simpler way with a reduction in technological operations.

The specified technical result is achieved due to the fact that the claimed rake containing a plate made of working elements spaced apart from each other, means for connecting the handle to the plate-shoulder, where the working elements are teeth, are curved, the shoulder has a fastening means for holding the rake elements, different the fact that the teeth on the rake are made in the form of plates, and the fastening means for holding the elements of the rake are two elements: a lock bar and a U-shaped profile, where the bar - the lock is located inside the U-shaped profile and fixed to its base by spot welding, and the lock bar has a number of holes made with a given step, and the U-shaped profile is a plate bent from both edges so that one curved edge has a number of made with at a predetermined pitch of the holes corresponding to the pitch of the holes of the lock plate, and through these holes in the bent edge of the plate and in the lock bar, the teeth are pushed into the bend of the other edge of the plate, which together with the ends of the protruding teeth and the lock bar pressed and tuleyka connected with fastening means for holding the elements of rake weld.

It is permissible that the teeth on the rake are made in the form of metal plates or wire with a diameter of 2.5 mm

It is permissible that the width of the teeth is from 5 to 6.5 mm, and the thickness is 0.8 mm.

It is permissible that the holes for the teeth are round or rectangular, or square, or triangular in shape.

Utility Model Implementation

The rake contains a plate of working elements spaced apart from each other, a means for connecting the handle to the tulle plate, where the working elements are teeth, made curved. At the same time, the tulle has a fastening means to hold the rake elements.

New is that the teeth on the rake are made in the form of a plate of flattened or spring wire, and the fastening means for holding the rake elements are two elements: a lock bar 8 (see Figure 2, Figure 3) and a U-shaped profile, where the lock plate 8 is located inside the U-shaped profile and fixed to its base by spot welding, and the lock plate 8 has a number of holes made with a given pitch 2. The U-shaped profile is a plate 1 (see Figure 1), bent from both edges so that one curved edge 4 has a number of holes with a given pitch of holes 2, corresponding to the pitch of the holes 2 of the lock-plate 8.

Through these holes in the bent edge of the plate 1 and in the lock bar, the teeth are pushed into the bend 3 of the other edge of the plate 1, which together with the ends of the protruding teeth 5 and the lock bar 8 are pressed.

If the tooth plates 5 are made of flattened tape, this simplifies the process of forming teeth, which can be made on one stamp, which cuts a certain length of the teeth, which in turn also reduces the number of technological operations.

The rake teeth are cut from a tape of flattened spring steel 65G.

The width of the tooth can be, for example, 5-6.5 mm, and the thickness 0.8 mm.

The number of teeth can be from 20-35 pcs.

A spring wire, for example, with a diameter of 2.5 mm, can also be used for a tooth.

The tulle itself 6 is connected to the fastening means for holding the rake elements by a welded joint 7.

As a fastening means for holding the rake elements, a steel sheet is used, from which the necessary size rake blanks are cut.

The holes 2 for the teeth can have any shape, not only round, but also rectangular, square, triangular, depending on the convenience of inserting teeth 5 into them.

Rakes can be made as follows.

Take a steel plate 1 (see Figure 1), perform a series of holes 2 from one edge, the number of which corresponds to the number of teeth 5. Then, the edges of the plate 3 and 4 are bent as shown in Figure 3 (A).

The lock plate 8 (see Figure 2) on the rake performs the function of holding the teeth 5 at the same distance so that they do not move (since the teeth are not welded to the metal, but are attached by this lock). The lock bar is bent by about 45 degrees, then spot-welded 7 to the base of the U-shaped profile.

Then, pre-prepared teeth 5 are inserted into the obtained U-shaped profile (see Fig. 3 (B)). The inserted tooth ends are also passed through the corresponding holes 2 in the lock-bar 8.

The inserted ends of the teeth 5 abut against the other curved edge 3 of the U-shaped profile formed from the plate 1 (see Fig. 3 (B)).

On the bending machine, the wall - the edge of the plate 4 is bent (figure 4). When the edge of the plate 4 is bent, the lock-lock 8 is unbent by 180 degrees and at the same time firmly holds and fixes the teeth, and also holds the teeth at the same distance. Planck-lock 8 - the main part of the rake, without it, teeth 5 will move in different directions. After they bend the wall - profile 3 (see Fig. 5), then make another bend of the wall - profile 3 in place with the teeth that are already inserted into the profile 3, bend in the place with the teeth 90 degrees (Fig. 6) the teeth are held firmly in the profile plate 3.

Then, the fastening means are welded to the back side of the plate 1 by a welded joint 7 of the body 6 (see FIG. 6).

The working edges of the teeth 5 are bent either before insertion into the holes 2, as shown in the drawings, or (not shown in the drawings), the working edges of the teeth 5 are bent after making a rake on the stamp at the same time, while the teeth are uniformly and equally bent.

As a result, just a few simple operations to insert the teeth into the holes and two bends produce a solid rake. When working with a rake, the teeth will not fly out, they will take a greater distance in width for cleaning the territory.
