Embodiment Construction

[0021] The tow-hook plow 1 shown in FIG. 1 can be used especially in coal mining as a coal plow for seam thicknesses of less than 1.5 m and optionally less than 0.6 m, which is designed as a tow-hook plow and includes A multi-part planer strut 10 symmetrically formed with respect to the direction of travel of the tow hook plow 1, which has two outer struts 11 and a middle strut 12, the plow 1 is The machine strut 10 is guided on a non-illustrated face conveyor, which can in particular be designed as a chain-type scraper conveyor. The plow body 2 for separating the ore to be mined, such as coal in particular, at the working face comprises a central plow base body 3 and two lateral tool holders 5, said plow base body being rigidly fixed, in particular welded to the central support plate 12 and is provided with a height-adjustable jacking frame 4, the tool rests 5 on the two sides are respectively swingably hinged on the planer base 3, and the two tool rests pass through accordin...

Abstract

The present invention relates to a sword plough (1) including a middle sword plate part (12) connected to the plural pieces type planer body (2) and two props (10) movable connecting with the outside prop piece (11). The guiding clamp on one side of the filling side for each prop piece is used for guiding the props in the chain guiding channel. In order to realize the fast and easy connecting by the planer drag chain and achieve the notable improved operating characteristic for the sword plough, on a slipping element (40) two chain clamp (41) are formed to connect the planer drag chain (6). The slipping element on one side of the filling side of the middle sword plate part (12) is removably inserted into a recess (13). The recess is limited by a clamp piece (17) in two traffic direction of the sword plough (1), which is provided with a guide bracket (18). The sword plate part exhibits a stop surface (16) for the slip element (40).

Description

technical field [0001] The invention relates to a tow hook planer, which comprises a multi-piece support plate consisting of a support plate fixedly connected to the middle of the planer body and two outer support plates movably connected with it; A guide clamp on one end of the filling side of each spreader member for guiding the spreader in a chain guide channel for the planer chain; A chain clamp in the running direction is used to connect the drag chain of the planer. Background technique [0002] A tow hook planer of the same type is known from DE 31 06 548 A1. In a tow hook planer, the planer support plate (Hobelschwert) engages from below a conveyor with a planer guide and a chain guide on the filling side, for example a chain scraper conveyor, and the planer chain on the support The rear ends of the plates are thus guided on the filling side in chain guide channels, each of which is built in on the conveyor. Coal is extracted economically with the tow-hook planer,...
