Material feed container for a thick-matter pump
The invention relates to a material feed receptacle for a thick matter pump comprising a receptacle lower part and a receptacle top that is detachably connected to the receptacle lower part, a two-part front wall, a rear wall, two two-part lateral walls, an upwardly pointing material feed opening delimited by a peripheral edge, and a pipe junction, which is situated inside the receptacle, can, on the entry side, swivel in an alternating manner in front of the delivery cylinder openings and which, on the output side, leads to a pressure pipe. The invention provides that the receptacle top has an upper lateral wall part and upper lateral wall parts, which have free ends and which extend away from the front wall part. The invention also provides that the peripheral edge has a first edge part, which forms an upper edge of the receptacle top, and ha a second edge part on the receptacle lower part, which is situated on the rear wall and is joined to the first edge part.
1. Material feed container for a thick-matter pump, comprising a material feed opening that points upward, two feed cylinder openings disposed in a container face wall, a tube switch disposed in the container interior, which can be pivoted alternately in front of the feed cylinder openings on the input side, and opens into a pressure pipe on the output side, and a hinged lid articulated onto a container wall and configured as a hollow plastic body having a first plastic shell that faces the material feed opening, and a second plastic shell forming an upper lid part.
2. Material feed container according to claim 1 , wherein the first plastic shell has a smooth surface that faces the material feed opening.
3. Material feed container according to claim 1 , wherein the second plastic shell has reinforcement beads.
4. Material feed container according to claim 1 , wherein the hinged lid is produced in one piece, using a rotation casting method.
5. Material feed container according to claim 1 , wherein the hinged lid has handles that are molded on.
6. Material feed container according to claim 1 , wherein the hinged lid has hooks for hooking in closure elements attached on a container wall.
7. Material feed container according to claim 1 , wherein the hinged lid is connected with the container face wall by means of at least one hinge and at least one gas spring.
8. Material feed container according to claim 7 , wherein the hinged lid has an attachment device for a rubber apron close to its side connected with the container face wall.
9. Material feed container according to claim 1 , wherein an intermediate ring is disposed in the feed cylinder openings, in each instance, the inner surface of which delimits a flow-through-channel for the thick matter, and the outer mantle surface of which bears at least one toe, whereby the container face wall has at least one partially circumferential inner groove in the feed cylinder opening, as well as at least one bayonet opening running from an inner surface facing the container interior to the inner groove, for accommodating the toe, forming a bayonet closure.
10. Material feed container according to claim 1 , wherein the material feed opening is delimited by a circumferential edge, wherein the material feed container has a lower container part and a container top releasably connected with the lower container part, a two-part face wall, a rear wall and two two-part side walls, in each instance, wherein the feed cylinder openings are disposed in the face wall, wherein the container top has an upper face wall part as well as upper side wall parts that extend away from the upper face wall part, with free ends, and wherein the circumferential edge has a first edge part forming an upper edge of the container top, and a second edge part at the rear wall side, following the first edge part, on the lower container part.
