The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] Please see Figures 1 to 6 The present invention preferably provides the following technical solution: a feed grinder with a pre-crushing function, comprising: a machine body; a particle size crushing roller assembly disposed inside the machine body, which can control the degree of pre-crushing of the feed by adjusting the gap between the rollers; a bidirectional cutter assembly disposed inside the machine body and below the particle size crushing roller assembly, for crushing long strips of material and preventing entanglement; and a double belt drive assembly disposed on the machine body, which provides bidirectional driving force to the bidirectional cutter assembly when the particle size crushing roller assembly is working.

[0024] The machine body in this application is equipped with a particle size crushing roller assembly and a bidirectional cutter assembly, respectively, combined with... Figure 2 , 3 As shown in Figures 4, 5, and 6, the particle size crushing roller assembly can control the pre-crushing degree of the feed by adjusting the gap between the rollers, while the bidirectional cutter assembly can receive the feed after the initial crushing by the particle size crushing roller assembly and perform a secondary pre-crushing process on the feed. Furthermore, due to the structural characteristics of the bidirectional cutter assembly, while crushing fibrous materials such as stems and vines, the bidirectional cutter assembly can prevent the fibrous materials such as stems and vines from entangled in the cutter.

[0025] In addition, the particle size crushing roller assembly and the bidirectional cutter assembly are linked together through a dual belt drive assembly. Figure 6 As shown, this design can not only adjust the speed of the bidirectional cutter assembly according to the crushing speed of the particle size crushing roller assembly, but also achieve the bidirectional driving effect of the bidirectional cutter assembly.

[0026] Furthermore, the machine body includes: a frame 111; a housing 112 mounted on top of the frame 111; a feed hopper 113 and a discharge hopper 114 disposed on the upper and lower sides of the housing 112 and communicating with the housing 112; and a long slot feed port 1121 opened on the front side of the housing 112, which can be used for the entry of fibrous materials.

[0027] Example 2

[0028] In another embodiment of this utility model, the particle size crushing roller assembly includes: two transmission blocks 217 mounted on the side wall of the housing 112; transmission shafts 211 rotatably mounted on the two transmission blocks 217 and running in opposite directions; a first conical roller 2121 disposed on each transmission shaft 211, the surface of the first conical roller 2121 being circumferentially provided with first crushing teeth 2122; and a telescopic rod 214 disposed on the side wall of the housing 112 and positioned between the two transmission blocks 217, wherein a second conical roller 2151 extending between the two first conical rollers 2121 is fixed at the telescopic end of the telescopic rod 214, the outer periphery of the second conical roller 2151 being circumferentially provided with second crushing teeth 2152, which are used to adjust the distance between the second crushing teeth 2152 and their adjacent first crushing teeth 2122 when the second conical roller 2151 moves telescopically.

[0029] This embodiment combines Figure 2 , 3 As shown, two transmission blocks 217 are distributed on both sides of the telescopic rod 214. The transmission shafts 211 rotatably mounted on the two transmission blocks 217, the first conical rollers 2121 fixed on the outer periphery of the transmission shafts 211, and the first crushing teeth 2122 fixed on the outer periphery of each first conical roller 2121 are distributed on both sides of the second conical roller 2151 and the second crushing teeth 2152 connected to the telescopic rod 214. When the second conical roller 2151 moves telescopically, the gap between the second crushing teeth 2152 and the first crushing teeth 2122 on both sides can be flexibly adjusted. This design can ensure the consistency of feed pre-crushing particle size as much as possible, while meeting the different pre-crushing requirements of different materials, so that most particles reach or approach the target size, and minimize the adverse effects of excessively large particles on subsequent crushing efficiency and excessively fine powder on increased energy consumption and reduced flowability.

[0030] Furthermore, the side wall of the chassis 112 is also provided with a meshing transmission assembly 213 for driving the two first conical rollers 2121 to run in opposite directions; the meshing transmission assembly 213 includes: two mounting slots opened on the side of the chassis 112 away from the transmission block 217, each mounting slot is provided with a transmission cylinder 2131, wherein one side of the two transmission cylinders 2131 is fixed to the two first crushing teeth 2122 respectively, and the other side of the two cylinders is fixed outward with mutually meshing transmission gear rings 2132; an L-shaped frame 2133 fixed to the outer wall of the chassis 112; and a motor 2134 mounted on the L-shaped frame 2133, wherein the output shaft of the motor 2134 is fixed to one of the transmission gear rings 2132.

[0031] Combination Figure 1 , 2As shown in Figure 4, the two transmission cylinders 2131 are rotatably installed inside the two mounting slots opened on the side wall of the housing 112. One side of each cylinder is fixed to the two first crushing teeth 2122, and the other side is fixed with mutually meshing transmission gear rings 2132. Therefore, when the motor 2134 fixed to one of the transmission gear rings 2132 runs, one of the transmission gear rings 2132 can rotate while the other transmission gear ring 2132 rotates in the opposite direction, so as to realize the reverse and synchronous rotation of the two first conical rollers 2121 and the two first crushing teeth 2122. In conjunction with the second conical roller 2151 fixed between the two first crushing teeth 2122, the pre-crushing process is realized.

[0032] Furthermore, a drive component 216 is provided on the side wall of the chassis 112 near the transmission block 217. The drive component 216 is equipped with a cylinder. The cylinder output end passes through a slot in the side wall of the chassis 112 and is connected to the telescopic rod 214 for driving the extension and retraction of the telescopic rod 214.

[0033] Combination Figure 2 , 3 As shown, the telescopic rod 214 is existing technology, consisting of a sleeve and a rod that is telescopically installed inside the sleeve. The sleeve is connected to the output end of the cylinder inside the drive component 216, and the rod is fixed to the second conical roller 2151. Therefore, when the cylinder is operated, the rod can be retracted or extended inside the sleeve, further realizing the telescopic movement of the second conical roller 2151 and the second crushing tooth 2152. In this application, the distance between the second conical roller 2151 and the first conical rollers 2121 on both sides can be adjusted by the telescopic movement of the second conical roller 2151.

[0036] Combination Figure 2 , 3As shown, a transmission rod 312 and a transmission sleeve 313 are rotatably mounted on the assembly block 311 and are distributed inwards and outwards. The mounting bracket 314 fixed at the end of the transmission rod 312 is provided with a ring of mounting strips 315. Each mounting strip 315 is provided with a number of first cutters 316 near the side of the transmission sleeve 313. These cutters correspond one-to-one with a number of second cutters 317 that are opened in a ring around the outer periphery of the transmission sleeve 313 and are staggered. When the transmission rod 312 and the transmission sleeve 313 run in opposite directions, the crushing operation of the number of sets of first cutters 316 and the number of sets of second cutters 317 can be achieved. While satisfying the crushing operation, the problem of long fiber materials being easily entangled in the first cutters 316 and the second cutters 317 is also overcome.
