Abstract

The utility model discloses a durable sweep rake, comprising a fixed cross beam (1) and rake teeth (2), wherein the fixed cross beam (1) is also provided with a rake handle sleeve (3), the rake teeth (2) and the fixed cross beam (1) are respectively made from metal, the rake teeth (2) and the fixed cross beam (1) are moulded in an integrated manner, and the rake teeth (2) are arranged on the lower surface of the fixed cross beam (1). By adopting the technical scheme, the rake teeth and the fixed cross beam are moulded in an integrated manner, on the one hand, a welding process is omitted, thus processing equipment and a mould are simplified, manpower and material resource are saved, energy consumption is reduced, and manufacturing cost is reduced; and on the other hand, when the sweep rake which is moulded in the integrated manner is used, the phenomenon that the rake teeth fall off easily can not be caused, thus service life of the sweep rake is prolonged.

Description

Durable harrow

Technical field

The utility model relates to a kind of small farm instrument, particularly a kind of durable harrow

Background technology

At present, harrow comprises fixed cross beam (1) and is positioned at the rake teeth (2) of fixed cross beam (1) one side that the middle part of said fixed cross beam (1) opposite side is provided with rabble arm cover (3); It is cylindrical mostly rake teeth is, said rake teeth and fixed cross beam welding, and such structure is after using a period of time; Rake teeth is prone to and comes off; Service life is not long, and welds the investment that will cause a lot of manpowers and the energy, makes that the manufacturing cost of harrow is high.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides the durable harrow of a kind of long service life, low cost of manufacture.

To achieve these goals; The technical scheme of the utility model is following: a kind of durable harrow; Comprise fixed cross beam (1) and be positioned at the rake teeth (2) of fixed cross beam (1) one side, the middle part of said fixed cross beam (1) opposite side is provided with rabble arm cover (3), and said rake teeth (2) and fixed cross beam (1) are processed by metal; And said rake teeth (2) and fixed cross beam (1) are one-body molded, and an end of said rake teeth (2) is arranged on the fixed cross beam (1).

Adopt technique scheme, said rake teeth and fixed cross beam are one-body molded, have saved the technology of welding on the one hand, make simplifications such as process equipment mould, have saved the man power and material, have reduced energy resource consumption, have reduced manufacturing cost; On the other hand, integrated harrow is not prone to the phenomenon that rake teeth comes off when in use, makes that the service life of harrow is elongated.

In technique scheme, said rake teeth (2) is flat, and the center is lower recess longitudinally, and forms protruding reinforcement (4) at the back side of concave face.Said rake teeth adopts flat, and the middle part is to lower recess, on the one hand; The rake teeth of flat than columniform rake teeth when boring soil owing to increase with the contact area of soil, so the user can be more laborsaving when using, in order to increase the mechanical strength of flat rake teeth self; We are designed to it; One side forms depression, and another side then forms protruding reinforcement, has increased the mechanical strength of rake teeth itself.

In technique scheme, the connecting portion of said rabble arm cover (3) and fixed cross beam (1) is provided with rabble arm cover reinforcement (5), and an end of said rabble arm cover reinforcement (5) is fixed on the rabble arm cover (3), and the other end is fixed on the fixed cross beam (1).Can increase the mechanical strength that the rabble arm cover is connected with fixed cross beam like this, make its difficult drop-off.

In technique scheme, in order to make the mechanical strength of fixed cross beam better, the thickness of said fixed cross beam (1) is 6-10mm.

In technique scheme, in order to make the intensity of rake teeth better, the thickness of said rake teeth (2) tooth root is 5-7mm, and the thickness of its crown is 1-2mm.

Beneficial effect: the utility model is reasonable in design, simple in structure, low cost of manufacture, and mechanical strength is high, long service life.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Embodiment 1, and shown in Fig. 1-3, the durable harrow of the utility model mainly is made up of fixed cross beam 1, rake teeth 2 and rake teeth cover 3; Rake teeth 2 is positioned at fixed cross beam 1 one sides, and the middle part of said fixed cross beam 1 opposite side is provided with rabble arm cover 3, and this is a prior art; Do not do at this and to give unnecessary details, key is: said rake teeth 2 and fixed cross beam 1 are processed by metal, and said rake teeth 2 is one-body molded with fixed cross beam 1; Wherein the thickness of fixed cross beam 1 is 6-10mm, and rake teeth 2 is flat, and the thickness of rake teeth 2 tooth roots is 5-7mm; The thickness of its crown is 1-2mm, and the center forms protruding reinforcement 4 longitudinally to lower recess at the back side of concave face; The connecting portion of said rabble arm cover 3 and fixed cross beam 1 is provided with rabble arm cover reinforcement 5, and an end of said rabble arm cover reinforcement 5 is fixed on the rabble arm cover 3, and the other end is fixed on the fixed cross beam 1.
