[0039] The outer wall of the feeding cylinder 1 is horizontally provided with a movable cylinder 18, a movable hole is horizontally formed through the movable cylinder 18, the movable hole is in a rectangular cross section, a movable plate 19 is horizontally movably arranged in the movable hole, the outer wall of the movable plate 19 movably abuts against the inner wall of the movable hole, the inner end of the movable plate 19 is hingedly provided with a linkage plate 20, the bottom of the second guide plate 16 is hingedly provided with an adjusting plate 21, the two sides of the adjusting plate 21 movably abut against the inner wall of the feeding cylinder 1, and the bottom is hingedly connected with the bottom of the linkage plate 20.

[0040] A plurality of adjusting holes 22 are vertically formed through the movable plate 19, a matching hole 23 is vertically formed through the movable cylinder 18, the matching hole 23 is in communication with any one of the adjusting holes 22, further comprising an adjusting pin 24 and an anti-dropping ball 25 with a diameter larger than the adjusting pin 24, the adjusting pin 24 can pass through any one of the adjusting holes 22 and any one of the matching holes 23, and the position of the movable plate 19 is adjusted.

[0041] The feeding device based on the pulverizer, wherein the bottom of the feeding cylinder 1 is in communication with the feeding opening of the pulverizer, that is, the material enters the pulverizer for crushing after passing through the feeding channel. After the material is added into the feeding cylinder 1 from the top of the feeding cylinder 1, the material falls downward under the action of gravity and is guided by the top of the guide piece 2 and then falls downward after passing through the inner wall of the guide piece 2 and the feeding cylinder 1. The material with a small particle size that does not need to be crushed enters the inner cavity of the guide piece 2 after passing through the first feeding hole 4 when the material moves on the top of the guide piece 2. Since the guide piece 2 is in an inclined state, the material with a small particle size is guided by the guide piece 2, moves downward into the discharge piece 3, and is discharged to the outside through the discharge piece 3. In this way, the separation of part or all of the large and small particles can be realized before the material enters the pulverizer, thereby increasing the proportion of the material that needs to be crushed in the pulverizer and ensuring the crushing efficiency.

[0042] In the actual crushing process, although the material with a small particle size does not need to be crushed, the material occupies part of the crushing resources of the larger material in terms of time and space in the crushing chamber. The material that does not need to be crushed is also easy to be further crushed, and even the particle size of the material is too small. Therefore, after the material with a small particle size is guided out and separated from the large material by the guide piece 2 and the discharge piece 3, the crushing efficiency can be ensured, and the small particle material can be prevented from being crushed too small.

[0043] Wherein in the actual crushing, the material enters into the feeding cylinder 1 through the top receiving part 14, and the material is easily added due to the large opening at the top of the receiving part 14. After the material is added to the receiving part 14, it is guided by the first guide plate 15 and the second guide plate 16, and then enters into the feeding cylinder 1 through the material channel. At this time, the angle of the adjusting plate 21 can be adjusted by adjusting the position of the movable plate 19, so that the opening size of the material channel can be adjusted, and thus the speed of the material entering into the feeding cylinder 1 can be controlled, so that the required balance between crushing and feeding can be achieved. When adjusting the angle of the adjusting plate 21, the adjusting pin 24 is pulled out upward, the position of the movable plate 19 is adjusted horizontally, and then the adjusting pin 24 is inserted into the corresponding matching hole 23 and adjusting hole 22 after the angle of the adjusting plate 21 is appropriate. If there is no adjusting hole 22 directly opposite to the adjusting hole 22 at a certain angle, the position of the movable plate 19 can be slightly adjusted so that the matching hole 23 communicates with the adjusting hole 22, which has little effect on the feeding speed of the material. The adjusting hole 22 has several rows (preferably three rows in this embodiment), and the adjusting holes 22 in different rows are in a staggered state, and the matching hole 23 has three, and each adjusting hole 22 corresponds to a row of adjusting holes 22, so that more precise adjustment can be achieved in actual operation.

[0044] Wherein the bulk material rod 17 not only can support and consolidate the second guide plate 16, but also can scatter the material, so that the material can be dispersed to act on the guide member 2. The guide member 2 has several upper and lower distributed, so that the material can fall from left to right, and then fall from right to left, and after several times of reciprocating, the material with smaller particle size can be guided out to the outside through the respective guide member 2 and discharge member 3. Moreover, when the material moves between the different layers of the guide member 2, the supporting bulk material member 5 not only can support the guide member 2, but also can scatter the material, so that the material falls more smoothly and prevents clogging, and also can better screen out small materials; at the same time, the second feeding hole 6 can also screen the material.

[0045] Wherein the top of the discharge member 3 is pointed, so that the residual material on the top of the discharge member 3 can be minimized; secondly, after the small particles enter into the guide member 2 and move downward to the bottom of the guide member 2, they are affected by the first guide member 7 and the second guide member 8, so that the material can enter into the discharge member 3 and be guided out, so that the material can be prevented from stacking in the guide member 2.

[0046] After the small particles are guided out by the discharge member 3, they will fall and act on the protection plate 11 and then fall downward; the material will form a slope on the protection plate 11, so that the subsequent material will impact on the slope formed by the material, thereby reducing the impact of the material on the inner wall of the collecting cover 9, and the collecting cover 9 is protected. After the small particle material falls to the bottom of the collecting cover 9, it is guided into the discharge channel 10 by the slope at the bottom of the collecting cover 9, and finally falls out from the bottom of the discharge channel 10. Meanwhile, there is a container or a conveying belt (not shown in the figure) at the bottom of the discharge channel 10 for collecting the small particle material. When the protection plate 11 is cleaned regularly, only the bolt on the cleaning door 13 (i.e. there is a bolt horizontally movable on the cleaning door 13, and there is a horizontal cylinder on the outer wall of the collecting cover 9, and the bolt is inserted into the cylinder to fix the cleaning door 13) is opened, and then the cleaning door 13 can be opened and the top of the protection plate 11 can be cleaned through the cleaning port.

[0047] The above description is only a description of the preferred embodiments of the present application, and is not any limitation on the scope of the present application. Any modification or modification of the above disclosure by a person skilled in the art belongs to the protection scope of the claims.
