Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a high-efficiency grass chopper. Background Art

[0002] In agriculture and animal husbandry, forage processing is extremely critical, affecting feed effectiveness and animal nutrition. Problems with traditional whole-plant feeding include inconvenient storage and transportation, low digestion efficiency, and difficulty for young and weak animals to eat, which has prompted the development of forage chopping technology. Chopping forage not only reduces the volume of forage, facilitating storage and transportation, but more importantly, improves feed utilization. The surface area of ​​chopped forage increases, which helps animal saliva to mix better with feed and promotes enzyme decomposition, thereby improving feed digestibility and nutrient absorption efficiency. For ruminants, finely chopped forage can also promote the activity of microorganisms in the rumen, further improving the nutritional value of the feed.

[0003] In the daily operations of many small and medium-sized farms and ranches, the forage chopping work requires compacting the fluffy forage to reduce the risk of clogging of the chopper. However, this pre-step and the subsequent feeding process currently mostly rely on manual operation. The bundling of the forage and the thrust of the feeding require a lot of manpower and the work efficiency is low. How to invent an efficient forage chopper to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

The cutting knife 8 is provided with a plurality of blades. The blades are slidably arranged with the ends of the upper and lower walls of the extrusion bin 3. The internal space of the extrusion bin 3 gradually becomes smaller from one side of the storage bin 4 to one side of the cutting shaft 6. The hay is transported from the direction of the storage bin 4 to the direction of the cutting knife 8 under the structure of the transmission machine. In the process of transporting the hay, the extrusion bin 3 naturally squeezes the hay and compacts the fluffy hay, eliminating the tedious process of manually compacting the hay, saving human resources and improving work efficiency.

[0023] Reference Figure 1-Figure 6The transmission mechanism includes a transmission motor 9 fixedly connected to the top of the base 1, and both side walls of the extrusion bin 3 are rotatably connected with a transmission shaft 14, wherein a rotating shaft bracket 10 is fixedly connected between the two stands 2, and the rotating shaft bracket 10 is rotatably connected with two lower blade shafts 11 and a speed regulating shaft 12, and the outer wall of the speed regulating shaft 12 is sleeved with a speed regulating wheel 13, and the output end of the transmission motor 9 and the speed regulating wheel 13, the speed regulating shaft 12 and the two lower blade shafts 11, and the speed regulating shaft 12 and the two transmission shafts 14 are all connected through a second belt transmission, and the outer wall of the lower blade shaft 11 is sleeved with a lower spiral blade 15, and the lower spiral blade 15 is located inside the extrusion bin 3, and a plurality of first shaft brackets 16 are fixedly connected to the inner side wall of the extrusion bin 3, and the end of the lower blade shaft 11 is rotatably connected to the first shaft bracket 16, and a plurality of second shaft brackets are fixedly connected to the inner upper side wall of the extrusion bin 3, and the second shaft bracket is rotatably connected with an upper blade shaft 17, and the outer wall of the upper blade shaft 17 is sleeved with an upper spiral blade 18, and the upper blade The ends of the shaft 17 and the transmission shaft 14 are both sleeved with gears.
