DETAILED DESCRIPTION
[0019] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0020] like Figure 1 - Figure 5 As shown, a fine grain and grass grinder includes a base frame 1, and a grinding box 2 installed on the top of the base frame 1 through a fixing mechanism, the fixing mechanism includes two groups of fixing components, and the two groups of fixing components are respectively located on both sides of the grinding box 2, the fixing components include two supporting legs 8, and a supporting plate 9 installed on the top of the two supporting legs 8, one side of the supporting plate 9 is fixedly connected to the outside of the grinding box 2, and a grinding mechanism is installed inside the grinding box 2, the grinding mechanism includes a rotating rod 3, two mounting plates 4 installed outside the rotating rod 3, a plurality of grinding components installed between the two mounting plates 4, and a rotating mechanism installed on the top of the base frame 1 for driving the rotating rod 3 to rotate, the rotating mechanism includes a rotating motor 10 installed on the top of the base frame 1, a rotating rod 11 installed at the output end of the rotating motor 10, and a pulley 12 installed on the rotating rod 11 and the outside of the rotating rod 3, the two pulleys 12 are connected by belt transmission, the tops of the two supporting plates 9 are respectively installed with fixed sleeves, the two ends of the rotating rod 3 are respectively rotatably connected to the inside of the two fixed sleeves, and the grinding box 2 and the box cover 13 are close to the side of the rotating rod 3 Two notches are provided for the use of the rotating rod 3. The crushing assembly includes a mounting rod 5 installed between two mounting plates 4, a plurality of slots 6 are provided on the outside of the mounting rod 5, and a crushing knife 7 is sleeved on the outside of the slot 6. The slot 6 can limit the crushing knife 7 to prevent the crushing knife 7 from colliding with the two crushing knives 7 when the crushing knife 7 rotates. The crushing knives 7 on each adjacent crushing assembly are staggered. A box cover 13 is hinged on one side of the top of the crushing box 2. When the crushing work is performed, the box cover 13 is fixed to the crushing box plate by bolts. A feed cylinder 14 and a discharge cylinder 15 are installed on the box cover 13, and a plurality of fixed plates 19 are installed on the outside of the rotating rod 3. A cutting knife 16 is detachably installed on one side of the plurality of fixed plates 19. The cutting knife 16 is fixed to the fixed plate 19 by a plurality of bolts, so as to facilitate the disassembly and replacement of the cutting knife 16, and the cutting knife 16 is located on one side of one of the mounting plates 4. A baffle plate 17 is installed on the outside of the rotating rod 3, and the baffle plate 17 is located on one side of the other mounting plate 4, and a plurality of rotating blades 18 are installed between the baffle plate 17 and the mounting plate 4.
[0021] It should be noted that when this kind of fine grain and grass grinder is in use, the rotating motor 10 is started, and the rotating motor 10 will drive the rotating rod 11 to rotate. Under the cooperation of the two pulleys 12 and the belt, the rotating rod 3 will rotate. When the rotating rod 3 rotates, it will drive the two mounting plates 4 to rotate. At this time, the multiple crushing components installed between the two mounting plates 4 will also rotate, thereby causing the multiple crushing knives 7 to rotate. When the user pushes the grain and grass from the feed barrel 14 into the interior of the crushing box 2, the grain and grass will be crushed under the action of the multiple crushing knives 7. Since the multiple crushing knives 7 are sleeved on the outside of the mounting rod 5, When the crushing assembly rotates, the multiple crushing knives 7 can rotate around the rotating rod 3 and can also rotate themselves, thereby expanding the crushing range of the crushing knives 7 and making the food and grass crushed more finely. When the rotating rod 3 rotates, it will drive the multiple cutting knives 16 and the rotating blades 18 to rotate. When the multiple cutting knives 16 rotate, they can perform preliminary crushing of the food and grass. The crushing assembly can perform secondary crushing of the food and grass, thereby improving the crushing effect. The multiple rotating blades 18 will generate wind force during the rotation process, and blow the crushed food and grass out through the discharge barrel 15. The feed barrel 14 is located on the side close to the cutting knives 16.
[0022] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
