Problems solved by technology
In the existing top cutting machine tools, the height of the cutting tool is generally fixed, and the cutting height remains unchanged. Therefore, the large green heads of the beet plants are not completely cut off, and the residual harmful nitrogen is not conducive to the sugar analysis. Large, serious waste of resources

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] Such as figure 1 As shown, the sugar beet imitation topping device of the present invention includes a double profiling rod mechanism 2 , a cutting knife 5 , a floating knife 6 and a floating knife height limiting mechanism 7 . The fixed seat 1 and the movable seat 3 are connected by a double profiling rod mechanism 2 . The bottom of movable seat 3 is fixed with cutter 5, guide spring 4 and slide shoe 8, and slide shoe 8 can protect cutter from damage during work. The top of floating knife 6 is connected with the bottom of movable seat 3. The floating knife 6 includes a floating knife body 601 and a floating knife position adjustment mechanism, and the floating knife body 601 is connected with the movable seat 3 through the floating knife position adjustment mechanism. The floating knife height limit mechanism 7 is connected with the double pr...

The invention relates to agricultural machinery, in particular to a sugar beet imitation topping device. Including double profiling rod mechanism, cutting knife, floating knife, floating knife height limit mechanism and floating knife position adjustment mechanism, double profiling rod mechanism includes fixed seat, movable seat, and upper and lower connecting rods connecting fixed seat and movable seat , the bottom of the movable seat I is fixed with a cutter, the top of the floating knife is connected with the bottom of the movable seat II, the height limit mechanism of the floating knife is connected with the double profiling rod mechanism; the double profiling rod mechanism includes a fixed seat, a movable seat Ⅰ, movable seat Ⅱ, and the upper and lower connecting rods connecting the fixed seat and the movable seat, one end of the upper link is connected with the rotating shaft on the top of the fixed seat, the other end of the upper connecting rod is connected with the rotating shaft on the top of the movable seat, and the lower connecting rod One end is connected with the rotating shaft at the bottom of the fixed seat, and the other end of the lower link is connected with the rotating shaft at the bottom of the movable seat. It realizes uniform topping of beets of different sizes, prevents excessive pressure of the floating knife on the top of the beet and causes damage to the beet, and ensures the integrity of the beet.
Description
technical field [0001] The invention relates to agricultural machinery, in particular to a sugar beet imitation topping device. Background technique [0002] Sugar beet is one of the main economic crops in northern my country and one of the two important sources of sugar in the sugar industry. The green tops of beets contain substances that are not conducive to sugar production, so the tops of beets should be trimmed. Beet topping can be done before or after digging. At present, the methods of manual multi-knife cutting and one-knife flat cutting are generally used in sugar beet producing areas in my country to cut tubers. The multi-knife cutting method is to use a knife to cut 5 to 6 blades from the bottom row of leaf scars at the root head of the root tuber like a pencil, with a thickness of 2 to 3 mm, so that the root head is slightly exposed. This kind of operation method has less loss of raw materials, but the labor intensity is high and the industrial efficiency is ...
