ES2222066A1 - Stone-raking and beach-cleaning machine has large drag screen inserted into the earth - Google Patents

Abstract

Tractor which is connected (2) to a trailer (1) and which can be used to calibrate the depth to which the front part of a large drag screen (4) is inserted into the earth (9), said screen taking the form of a mesh drum (4.1) which is fixed using metallic hoops (4.2) and stiffeners (4.3). The inventive machine is provided with deflector blades (4.4) for separating and screening the earth using a combination of the forward motion of the trailer and the rotation of the screen in relation to lower side bearings (10) and front side bearings. In this way, the earth is screened and the larger stones and objects to be removed pass through the upper rear area.

Description

Improvements introduced in the object of the patent of invention nº 200101645, called cleansing machine and beach cleaner

Object of the invention

The present invention relates to improvements introduced in the object of the invention patent No. 200101645 denominated cleansing machine and beach cleaner.

This invention characterizes a special construction of the drive means and vanes solidarity with the sieve, its sectorized construction, is also develops the drag spiral cited in the patent main, as well as a metallic collection sheet is incorporated and a tilting drawer for stone and waste disposal.

Background of the invention

The patent cleansing machine 200101645 of the applicant, as a machine for agricultural uses and for beaches, is intended for the selection and removal of stones and garbage

This invention characterized a trailer provided with a large drag screen, with front frame partially sunk in the ground and with a cylindrical drum longitudinal, provided with a spiral of drag of stones, internal or, with some blades, equivalent in this function of separation, the screen being interchangeable and being operated well hydraulically, with hydraulic motor and transmission belt or directly from the tractor, turning on some bearings lower lateral support and being centered by other bearings lateral, which also supports the front tilt of the frame, completing the set an evacuation hopper of stones and a transverse conveyor belt, which unloads in a circulating vehicle parallel to the trailer or in a tank storage.

The applicant is unaware of the existence of elements and equipment of the features of the invention that Now we proceed to describe.

Description of the invention

The present invention relates to improvements introduced in the sieve, the drive of the same and in the means of evacuation of the object of the invention patent No. 200101645, called cleanser and beach cleaning machine.

This invention characterizes a special construction of the screen itself, in order to avoid disassembly almost complete machine for replacing it when, to separate land or beach sand of different dimensions from grain, when moving from one land to another or from one type of beach to another different, there are different dimensional requirements of Mesh light.

For this purpose the sieve drum is sectorized through a regular rigid structure, consisting of a diversity of frameworks provided with the corresponding sectors of mesh, which are screwed to it, thus easily replacing these frames for others with different light mesh, more suitable in each case.

The screen drive has a motor hydraulic charge of rotating the pneumatic wheel pressing firmly on the transmission band of the movement to that.

At the exit. of the sieve are arranged vanes, slightly deviated from the radial arrangement and rotating solidarity with it, which collect stones and waste and they pour them on a sloping metal sheet, which directs them to the outer drawer which is unloaded by lifting and tilting simultaneous with the help of vertical pistons arranged in the rear area of the trailer that supports the sieve.

The circular tubular housing of the vanes, annex to the sieve and immediately prior to the exit of waste and of stones to the drawer, it is of variable dimensions in its diameter, in depending on the characteristics of the land on which it is going to use the machine

It also has a host that is responsible for feeding and circulation inside the sieve drum of Products collected from the front frame.

This auger is built in sheet steel, thicker at its front end for deformation-free absorption of the blows of the stones and, progressively and towards the end opposite, of smaller thickness and even perforated to facilitate the Earth or sand outlet.

In the case of use of the machine on beaches, incorporates to it, in its later zone, in the previous one or in both rollers, rotating or not and intended to flatten the ground, removing the grooves of the tractor wheels and dl trailer, as well as the marks left on it by the front Forward.

Description of the drawings

This descriptive report is complemented, with a set of drawings, illustrative of the preferred example and never limiting the invention.

Figure 1 is a rear view of the trailer in which can be seen the pistons, the raised drawer and the blade of discharge of stones and waste.

Figure 2 shows a detail of it area, also with 1 raised drawer, as well as with the sheet and the blades

Figure 3 is a partial perspective of the side of the trailer, with the drawer disassembled and showing the screen sectorized, as well as the accommodation of the blades.

Preferred Embodiment of the Invention

In view of the foregoing, the The present invention relates to improvements introduced in the Patent No. 200101645, of cleansing machine and beach cleaner, essentially characterized by having the sieve of a diversity of meshes (1.1) of different light based on sectorizing the drum (1) of the sieve with a regular rigid structure (1.2), constituted by a diversity of frames (1.3 bolted to it, arranging the operation of the screen of a hydraulic motor (2) which rotates the pneumatic wheel (2.1) that firmly presses the band of transmission (2.2).

Some vanes (3.1), slightly deviated from the radial and turning arrangement in solidarity with the sieve, and incorporated in a housing (3) of variable diameter, collect and pour the stones and debris on a sheet (4) of metal discharge in pending, which directs them to the drawer (5), which is unloaded by simultaneous lifting and tilting with the help of some pistons (6),  feeding and removing the collected products endless (7) built in sheet steel, thicker at its front end and, progressively thinner and perforated.

In beach machines the machine incorporates in its rear area, in the previous one or both, rollers, rotating or not, to flatten the earth and eliminate furrows and marks.

It does not alter the essentiality of this invention variations in materials, shape, size and arrangement of component elements, described in a non-limiting manner, sufficient this one to proceed to its reproduction by an expert.

Claims (2)

1. Improvements introduced in the object of the invention patent No. 200101645, called cleanser and cleanser, essentially characterized by having the screen of a variety of meshes (1.1) of different light based on sectorizing the drum (1) of the sieve with a regular rigid structure (1.2), constituted by a variety of frames (1.3) bolted to it, providing the actuation of the screen of a hydraulic motor (2) that rotates the pneumatic wheel (2.1) that firmly presses the band of transmission (2.2), while pallets (3.1), slightly deviated from the radial arrangement and integral with the sieve, and incorporated into a housing (3) of variable diameter, collect and pour the stones and debris onto a sheet (4) of metallic discharge in slope, which directs them to the drawer (5), which is discharged by simultaneous lifting and tilting with the help of pistons (6), feeding and removing the collected products An endless (7) built of steel sheet, thicker at the front end and progressively smaller and perforated. 2.
