Description
Technical Field
[0001] The utility model relates to a grass chopper and crusher, belonging to the technical field of grass choppers. Background Art
[0002] The hay chopper uses corn stalks, wheat straw, rice straw and other crops as processing materials, and produces feed processing equipment suitable for livestock breeding cattle, sheep, horses and deer feed through mechanical crushing such as chopping and cutting. At present, the chopping discharge port and the filament discharge port in the hay chopper are staggered, and the filament discharge port is located below the chopping discharge port. At the same time, the filament knife roller and the chopping knife roller are also staggered (see Figure 7 ), the distance that the material travels from the grass-chopping chamber into the silk-softening chamber increases, which makes it easy for the material to choke or get blocked, and the distance between the end of the silk-softening discharge port and the grass-chopping chamber is greater than the distance between the shredding discharge port and the grass-chopping chamber, so there is a situation where the chopped material falls on the silk-softening discharge port. Utility Model Content
[0003] In view of the shortcomings of the prior art, the utility model aims to provide a grass chopper and crusher to solve the problems raised in the above-mentioned background technology. The utility model shortens the distance for materials to enter the silk-softening chamber from the grass chopper chamber to prevent choking and blockage, and at the same time prevents the materials discharged from the shredding discharge port from falling on the silk-softening discharge port.
[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a grass chopper, comprising a base, a grass chopper chamber is installed on one side of the upper surface of the base, a chopper roller is rotatably installed in the upper position of the grass chopper chamber, one end of the chopper roller extends to the outside of the grass chopper chamber and is installed with an upper pulley, a silk-softening roller is rotatably installed in the lower position of the grass chopper chamber, one end of the silk-softening roller extends to the outside of the grass chopper chamber and is installed with a lower pulley, a feeding mechanism is installed at the upper position of one side surface of the grass chopper chamber, a chopping discharge port and a silk-softening discharge port are respectively installed at the upper and lower positions of a side of the grass chopper chamber away from the feeding mechanism, a detachable end plate is installed between the chopping discharge port and the silk-softening discharge port, a partition is installed on one side of the end plate, and the partition is inserted between the chopper roller and the silk-softening roller.
[0005] The transmission gear is connected with the gear of the driving mechanism, and the transmission gear is connected with the gear of the driving mechanism, and the transmission gear is connected with the gear of the driving mechanism, and the transmission mechanism ...
[0006] Furthermore, a shaft is rotatably installed in the upper position inside the feed cover, and a plurality of stirring heads for stirring the grass are installed on the outer surface of the shaft. One end of the shaft extends to the outside of the feed cover and is connected and fixed with a driven gear, and the driven gear is meshed with a linkage gear, and the linkage gear is rotatably connected to the feed cover, and the linkage gear is meshed with the lower gear.
[0007] Furthermore, a U-shaped frame is connected and fixed to the bottom of the feed cover, and both ends of the U-shaped frame are connected and fixed to the base.
[0008] Furthermore, the outer surfaces of the upper feed roller and the lower feed roller are processed with a plurality of evenly arranged strip grooves, and the strip grooves are arranged along the length direction of the upper feed roller and the lower feed roller.
[0009] Furthermore, the end plate is an L-shaped structure, and the end plate is connected and fixed to the grass-cutting chamber by screws.
[0010] Beneficial effects of the utility model:
[0011] 1. Install the chopping knife roller at the upper part of the grass chopping chamber, and install the silk-softening knife roller at the lower part of the grass chopping chamber, and install a partition between the chopping knife roller and the silk-softening knife roller. After the partition is pulled out, the chopped material can fall into the lower part of the grass chopping chamber and be crushed by the silk-softening knife roller. At this time, the chopping knife roller and the silk-softening knife roller are arranged vertically, thereby shortening the distance of material transfer and preventing choking and blocking.
[0012] 2. After the partition is inserted between the chopping knife roller and the silk-spinning knife roller, the chopped material is discharged through the chopping discharge port. At this time, the chopping discharge port and the silk-spinning discharge port are in an upper and lower arrangement state, and the chopping discharge port and the silk-spinning discharge port are flush with each other, so the material discharged from the chopping discharge port will not fall on the silk-spinning discharge port.
