DE2841406A1 - DEVICE FOR SPREADING FERTILIZER ON THE SOIL - Google Patents

Description

g 28 4 I 4 O

The present invention relates to an apparatus which is mounted on a liquid distributor to ensure an even Ensure distribution of fertilizers on the soil.

In particular, the invention relates to a device such as it in the applicant's French patent 74 36 407 dated October 31, 1974.

The device according to the above patent is used to spread fertilizers in granular form and consists of a housing in the general shape of an isosceles triangle, has two parallel mounted cover plates, which with each other through a common wall connected between the two same sides are, with the angle lying on these two same sides receiving a nozzle that closes on a manifold is attached and opens into the interior of the housing, while the third sides are free for an opening for outflow of granules, the housing containing pins inside, which are at right angles between its two cover plates, which are mounted in parallel to. these are used, as well as baffles, also used at right angles to the cover plates mentioned and mounted so that the flow of granules passed through the nozzle into the housing impinges diametrically on the pins and so gradually divided into two equal amounts, so that through the opening an even layer of granules trickles.

Previously, such a device was made of metal and consisted of a main housing with tenons and baffles and a cover attached to the housing and fastened with screws. This production is relatively cumbersome and expensive. In addition, in order to function properly, the device must be kept scrupulously clean. You have to do that

To be able to clean the inside, regularly unscrew the cover. This makes cleaning impractical.

The aim of the present invention was, inter alia, to produce a device of the type mentioned, but it is essential easier to manufacture and easy to clean thanks to convenient dismantling.

The present invention is a device consisting of a housing in the general shape of an isosceles Triangle consists, has two cover plates mounted in parallel, which are connected to each other by a common wall between the two same sides are connected, in which on these A connecting piece is attached to the two same sides adjacent angle, which is attached to the distributor and into the interior of the housing opens, while the third sides are free for an opening for the spread of granules, whereby one enters the housing, between its two parallel mounted cover plates, at right angles to these, pegs and baffles have been used, which are arranged so that the.through the nozzle in the housing directed stream of granules strikes diametrically on the cones and so gradually divided into two equal amounts so that an even layer of granulate flows out through the opening, the device being characterized in that the housing is made in two parts, the first part of which consists of the two parallel mounted cover plates of the wall that connects the two same sides with the nozzle that ■ this part is still made of molded plastic material, while the second part, also made of molded plastic material, consists of a plate, the dimensions of which correspond to the internal dimensions of the housing, is connected to the housing and intermittently on a surface that has tenons and baffles.

This arrangement results in a device which is particularly simple and inexpensive to manufacture and in which one for the purpose

cleaning is very easy through the spreading opening of the plate can decrease from the first part.

According to a "special form of construction, the two are precise on the same sides of the panel with an edge that rests on the inner surface of the wall.

There now follows a detailed description of the invention with reference to a particular embodiment, which is shown in the enclosed Drawings is represented.

Pig. 1: perspective view of the top and bottom of the device in the open state;

Pig. 2: elevation of the device;

Pig. 3: Representation in section along line III-III in Pig. 2

The device shown in the Figures comprises a housing 1 of molded plastic material having two cover plates 2, 3, each of which has the general shape of an isosceles triangle, its two equal sides 4, 5 through one Side wall 6 are connected, while the sides 7 and 8 are free, and so between them an opening for the spread 9 space finds.

The housing 1 has at its opposite the expansion opening 9 At the end of a nozzle 10, which is connected by an elastic hose to a distributor device for fertilizers in granular form and opens into the housing.

The housing 1 is made of molded plastic material. The cover plates 2 and 3 contain ribs 11, so that a certain reinforcement of the cover plates is achieved.

In the housing 1 there is a plate 15, also made of molded Plastic material, in the porm of the interior of the housing 1,

The plate 15 has the shape of the support plate 16, on the surface of which pins 17 and baffles 18 are placed at right angles are.

The two sides of the plate 15, which are to lie exactly on the wall 6, are delimited by a sand.

The pins 17 are arranged so that the granulate stream, the flows in through the nozzle 10, strikes the pin radially and is divided into two equal amounts, the Sheets 18 facilitate this division.

A part of the pin 17 is hollow so that screws 20 can be attached with which the plate 15 is fixed to the housing 1 will.

Since the whole device is light, two screws are sufficient for fastening. Mainly self-tapping screws are used, which cut a mating thread in the hollow tenon.

The design of the device is therefore particularly simple. The plate 15 can be used to clean the pins 17 and baffles remove from housing 1 without difficulty.

Of course, the invention is not limited to that described here and shown execution limited. Numerous changes to details are possible without affecting the framework of the invention would be exceeded.
