DETAILED DESCRIPTION

[0014] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0015] like Figure 1 to Figure 3 As shown, a material crusher includes a casing 1, a feed port is opened on the casing 1, a feed hopper 12 is installed on the feed port, and the feed hopper 12 is fixed to the casing 1; the setting of the feed hopper 12 can make the material enter the casing 1 more conveniently.

[0016] A partition 2 is fixedly provided inside the casing 1, and the partition 2 divides the inside of the casing 1 into a crushing chamber 1 22 and a crushing chamber 2 23. The crushing chamber 1 22 is respectively equipped with two crushing rollers 221, a guide plate 1 222 and a guide plate 2 223 from top to bottom. The outer wall of the casing 1 is equipped with a power mechanism 5 for driving the two crushing rollers 221 to rotate; the power mechanism 5 is set to drive the two crushing rollers 221 to rotate, and when the two crushing rollers 221 complete material crushing, the crushed material will fall onto the guide plate 1 222.

[0017] The power mechanism 5 includes a motor 2 51 fixed to the outer wall of the casing 1, a worm 52 is fixed on the output shaft of the motor 2 51, the bottom end of the worm 52 is rotatably connected to a support plate 521, and two symmetrical bearing seats 55 are fixed on the top of the support plate 521, and the two bearing seats 55 are each provided with a rotating shaft 54 ​​that passes through the outer wall of the casing 1 and is respectively fixed to the two crushing rollers 221, and a worm wheel 53 that meshes with the worm 52 is fixed on the rotating shaft 54, and a gear 1 56 and a gear 2 57 are respectively fixed on the two rotating shafts 54; The starting of the motor 2 51 can drive the worm 52 to rotate. When the worm 52 rotates, it drives the gear 1 56 to rotate. The rotation of the gear 1 56 can drive the gear 2 57 to rotate. The rotation of the gear 1 56 and the gear 2 57 in different directions can drive the two rotating shafts 54 to rotate inside the two bearing seats 55 respectively. When the two rotating shafts 54 rotate in different directions, they can respectively drive the two crushing rollers 221 to rotate in different directions. The rotation of the two crushing rollers 221 in different directions can ultimately achieve the effect of crushing the materials.

[0018] A plurality of through holes 224 are provided on the guide plate 1 222 and the guide plate 2 223 and are arranged at an inclination. A through slot 21 is provided on the partition plate 2. The through slot 21 is penetrated at the tail of the guide plate 1 222 and is located inside the crushing chamber 23. An arc-shaped screening shell 231 is fixedly provided below the tail of the guide plate 1 222. When the crushed material passes through the two crushing rollers 221 and falls onto the guide plate 1 222, the material reaching the size requirement passes through the through holes 224 on the guide plate 1 222 and falls onto the guide plate 2 223. Since the guide plate 1 222 is arranged at an inclination, the remaining material on the guide plate 1 222 will fall into the screening shell 231.

[0019] A baffle 232 is fixedly arranged on the screening shell 231 and a crushing roller 233 is installed inside. One end of the crushing roller 233 passes through the outer wall of the casing 1 and is fixedly arranged with a motor 4. The baffle 232 plays a blocking role to prevent the materials on the guide plate 222 from passing through the baffle 232 and falling into the crushing chamber 23. When the materials inside the screening shell 231 reach a certain level, the motor 4 is started to drive the crushing roller 233 to perform the crushing operation.

[0020] A plurality of discharge holes 234 are provided at the bottom end of the screening shell 231, and the plurality of discharge holes 234 are of the same size as the plurality of through holes 224. A collecting box 3 is provided under the guide plate 223 and the screening shell 231. Since the guide plate 223 is inclined, when the material on the guide plate 1 222 falls into the guide plate 223, the material will eventually pass through the plurality of through holes 224 on the guide plate 223 and fall into the collecting box 3; when the crushing roller 233 in the screening shell 231 performs a crushing operation, the crushed material reaching the required size will eventually fall into the collecting box 3 through the plurality of discharge holes 234.

[0021] Both sides of the outer wall of the casing 1 are provided with discharge troughs 11 that cooperate with the collection box 3. Through the setting of the two discharge troughs 11, the two collection boxes 3 can be pushed into or out of the casing 1 respectively; four universal wheels 31 are fixed at the bottom of the two collection boxes 3, and a handle 32 is fixed on one side of the collection box 3. When the crushed material inside the collection box 3 reaches a certain level, the operator can push the collection box 3 out through the handle 32, and the four universal wheels 31 play a role in facilitating transportation.

[0022] By setting the power mechanism 5, the two crushing rollers 221 can be driven to rotate in different directions respectively, and the two crushing rollers 221 can rotate in different directions to crush the materials. By setting the motor 4, the crushing roller 233 can be driven to crush the materials. By crushing the materials for many times, it can be ensured that the materials meet the size requirements.
