Description

Technical Field

[0001] The invention relates to a land reclamation machine, and more particularly to a cutting drum of a land reclamation machine. Background Art

[0002] The opener can clear the ground, create and maintain woodland channels, clear and maintain vegetation, trim trees and hedges, cover trees and hedges to the ground or create firewalls by rotating the cutting drum installed at the front end. When performing relevant rotary cutting, ground clearing and open land, some ground will have some ferrous metal, which will damage the cutting teeth. Although the cutting teeth can be replaced after damage, there is no equipment on the market that can remove metal from the ground before open land. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a cutting drum for a land reclamation machine, which has the beneficial effects of convenient flipping of the debris cover, convenient replacement of the cutting teeth and the ability to remove ferromagnetic metal on the ground.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cutting drum of a land reclamation machine, comprising a covering mounting frame placed at the front end of the land reclamation machine, and a cutting drum that can realize rolling cutting and is arranged on the mounting frame; it is characterized in that: a plurality of detachable cutting teeth are arranged on the cutting drum; the cutting teeth are spirally arranged on the cutting drum; the mounting frame comprises an articulated debris cover arranged above the front end to cover the cutting rolling; it also comprises a heavy steel structure arranged on both sides below the front end of the mounting frame; the heavy steel structure is connected to the mounting frame by screws; a magnetic adsorption device is rotatably arranged at the front end of the mounting frame.

[0005] By adopting the above technical solution: the opener drives the cutting drum to perform rolling cutting through a standard gear motor or a piston motor, which is generally arranged in a mounting frame or driven by a gear or belt arranged in the mounting frame, thereby driving the cutting drum to rotate, and the cutting drum is connected to the mounting frame through a large bearing. The installation and drive of the cutting drum belong to the prior art. The cutting drum in the prior art is replaceable. Generally, the cutting drum is replaced after the cutting teeth are damaged, but there is no structural setting for replacing the cutting teeth. By setting a detachable cutting tooth, a single severely worn cutting tooth can be replaced. At the same time, the cutting teeth are spirally arranged on the cutting drum to facilitate the selective cutting of the cutting drum and to lift the debris along the spiral arrangement square after cutting the grass and wood to avoid the accumulation of debris in the mounting frame; and the setting of the articulated debris cover can block the raised debris and make the debris fall back to the ground. The articulated setting can realize the opening of the debris cover, which is convenient for cleaning and maintenance of the cutting drum. At the same time, the heavy steel structure can improve the overall strength of the mounting frame. The sturdy steel structure can cope with the most stringent covering tasks. At the same time, the low-profile design of the entire structure gives it good visibility.

[0006] The present invention is further configured as follows: the magnetic adsorption device includes a strip plate; a mounting hole is provided at one end of the strip plate; a strip protrusion with a semicircular cross-section is also provided on one side of the strip plate; a through hole is provided on the strip protrusion; a mounting rod is detachably fixedly installed in the through hole; the mounting rod is hollow; an electromagnet is fixedly connected to the end of the mounting rod away from the strip plate; a threaded hole is provided on the side of the strip plate away from the strip protrusion; the threaded hole is communicated with the through hole, and the axis of the threaded hole is perpendicular to the axis of the through hole; after the mounting rod is plugged into the through hole, the screw is threadedly connected to the threaded hole and the end face of the screw is abutted and fixed to the mounting rod.

[0007] By adopting the above technical solution: the magnetic adsorption device can adsorb magnetic metal on the cleared ground, thereby avoiding damage to the cutting teeth when the cutting drum rotates and cuts; the metal is mainly adsorbed by a small lifting electromagnet, which adsorbs the metal when power is on. The entire magnetic adsorption structure can rotate relative to the mounting frame and adjust the distance between the electromagnet and the cleared ground. Of course, the use of the magnetic adsorption device has certain limitations. When there are obstacles such as trees or rocks on the side of the mounting frame, the magnetic adsorption device will be affected. Therefore, the rotation of the strip plate relative to the mounting frame can avoid such problems. The structural setting of the entire magnetic adsorption device can achieve the above effect. The mounting holes on the strip plate are used for rotational connection with the screws between the heavy steel structure and the mounting frame, and the through holes on the strip protrusions are used to install the mounting rod. The hollow setting of the mounting rod is used to pass the power wire. The electromagnet is set at the lower end of the mounting rod and is connected to the power wire. The mounting rod is squeezed and fixed by the screw end face on one side.

[0012] The present invention is further configured as follows: the cutting tooth is connected to the lower side of the connecting seat, and the contact surface with the connecting seat is L-shaped; the cutting tooth is opposite to the threaded hole and a threaded hole is arranged on the opposite surface; an arc-shaped guide surface is arranged on the rear side of the lower end of the cutting tooth, and a sharp corner is arranged at the front end; there are two sharp corners, and a groove guide surface with a semicircular cross-section is arranged on the front side of the cutting tooth between the two sharp corners.

[0013] By adopting the above technical solution: the structural setting of the cutting teeth, through the screws passing through the connecting seat and then threadedly connected to the threaded hole, can achieve detachability, the arc guide surface facilitates the rotational cutting of the cutting drum, and the setting of the two sharp corners can realize the blasting of objects, thereby realizing land reclamation.
