Feed-mixing wagon

Abstract

A feed-mixing wagon for animal feed, including a frame with a drive, a container with a continuous wall with a feed-unload opening, a feed auger which is arranged in the container for mixing and cutting animal feed and including an auger shaft and an auger body which is arranged around it in a spiral which has several blades. The blades include at least one blade of a first, long type and at least one blade of a second, short type, and at least one blade of the short type is situated closer to the bottom than at least one blade of the long type. As a result of the various blades in the described configuration, the cutting and mixing behaviour can be adjusted in an optimum way.

         14 . A feed-mixing wagon for mixing and unloading animal feed, and comprising:
 a frame with a drive,   a container which is arranged on the frame and is open at the top, with a bottom and a continuous wall arranged thereon and a closable feed-unload opening in the wall, at least one feed auger which is arranged in the container and is rotatably drivable in a direction of rotation about a substantially vertical axis of rotation, which feed auger is arranged to mix and cut animal feed which has been introduced into the container and comprising an auger shaft and an auger body which is arranged around it in a spiral and has an outer edge, on which outer edge a plurality of blades are provided,   wherein the blades comprise at least one blade of a first, long type and at least one blade of a second, short type, wherein the long type is longer than the short type, and wherein at least one blade of the short type is situated closer to the bottom than at least one blade of the long type.   
     
     
         15 . The feed-mixing wagon according to  claim 14 , wherein a blade of the first type is provided as top blade on the outer edge. 
     
     
         16 . The feed-mixing wagon according to  claim 14 , wherein exactly two blades of the first type are provided on the outer edge. 
     
     
         17 . The feed-mixing wagon according to  claim 16 , wherein one of the two blades of the first type is provided substantially halfway up the feed auger. 
     
     
         18 . The feed-mixing wagon according to  claim 14 , wherein at least as many blades of the second type are provided on the outer edge as blades of the first type, in particular more blades of the second type than blades of the first type. 
     
     
         19 . The feed-mixing wagon according to  claim 18 , wherein a first number of the blades of the second type are provided below a bottom blade of the first type, and a second number of the blades of the second type are provided above the bottom blade of the first type, wherein the first number is at least equal to and is preferably larger than the second number. 
     
     
         20 . The feed-mixing wagon according to  claim 14 , wherein the blades, viewed in vertical projection on the feed auger, are distributed substantially evenly over an outer periphery of the feed auger. 
     
     
         21 . The feed-mixing wagon according to  claim 20 , wherein at least the blades of the first type, viewed in vertical projection on the feed auger, are distributed substantially evenly over the outer periphery of the feed auger. 
     
     
         22 . The feed-mixing wagon according to  claim 14 , comprising a motor arranged on the frame for rotatably driving the feed auger, wherein the drive of the frame comprises a motor, in particular wherein the feed-mixing wagon is an autonomous feed-mixing wagon. 
     
     
         23 . A feed-mixing wagon for mixing and unloading animal feed, and comprising:
 a frame with a drive,   a container which is arranged on the frame and is open at the top, with a bottom and a continuous wall arranged thereon and a closable feed-unload opening in the wall,   at least one feed auger which is arranged in the container and is rotatably drivable in a direction of rotation about a substantially vertical axis of rotation, which feed auger is arranged to at least mix animal feed which has been introduced into the container and comprising an auger shaft and an auger body which is arranged around it in a spiral and has, viewed in the direction of rotation, a bottom front edge which is situated closest to the bottom during rotation of the feed auger and extends in a substantially horizontal plane,   wherein a greatest chord of the bottom front edge extends through the auger body and wherein a line through said chord extends, viewed in the direction of rotation, in front of the axis of rotation.   
     
     
         24 . The feed-mixing wagon according to  claim 23 , wherein the bottom front edge is continuously curved, in particular with a local radius of curvature directed radially towards the auger body. 
     
     
         25 . The feed-mixing wagon according to  claim 24 , wherein the feed auger comprises a transition which extends around the auger shaft, between the bottom front edge and the auger body, which transition in particular comprises an edge face which stands at an oblique angle with the horizontal as well as an adjacent horizontal face portion which extends between the edge face and an end radius of the auger body which is arranged as an auger helix body.
