[0022] The following will be combined with the attached Figures 1 to 3 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a hammer mill feeding structure through improvement, such as Figure 1-Figure 3As shown, a feeding structure of a hammer mill comprises a mounting frame 1 and a conveying structure 2, wherein the mounting frame 1 comprises an upper roller 101 and a lower roller 102, wherein the upper roller 101 is rotatably arranged at the top of the mounting frame 1, and the lower roller 102 is rotatably arranged at the bottom of the mounting frame 1; the conveying structure 2 comprises a second conveyor belt 201 and a tipping bucket 202, wherein the tipping bucket 202 is fixedly arranged on the second conveyor belt 201, and the second conveyor belt 201 is movably arranged on the upper roller 101; a first conveyor belt 104 is movably arranged on the lower roller 102, and a plurality of vertical plates 105 are fixedly arranged on the first conveyor belt 104; vibration structures 203 are fixedly arranged on both sides of the tipping bucket 202, a screen frame 111 is further arranged on the side of the mounting frame 1, and a filter screen 112 is arranged at the bottom of the screen frame 111.

[0024] In this embodiment: when the hammer mill feeding structure is used, the raw material is first placed in the raw material box 103, and then the motor 107 is turned on. The motor 107 drives the lower roller 102 to rotate through the belt 108. The upper roller 101 is also rotated under the drive of the external driving device, and the conveying structure 2 also rotates with the upper roller 101. The raw material in the raw material box 103 is driven by the tipping bucket 202 and moves upward. When it moves to the position of the vibration structure 203, the extrusion blocks 206 on both sides of the tipping bucket 202 will vibrate and contact with the vibration rod 110, so that the materials adhered to the bottom of the tipping bucket 202 fall off. The side of the extrusion block 206 is an arc structure, so when the two sides of the tipping bucket 202 come into contact with the vibration rod 110, the extrusion block 206 will move inward along the threaded rod 205. When the tipping bucket 202 leaves the vibration structure 203, the extrusion block 206 returns to its original state under the action of the spring 207. At this time, the raw materials in the tipping bucket 202 fall into the screen frame 111, and the raw materials fall into the entrance of the hammer mill after being screened by the filter screen 112. During the feeding process, the scattered raw materials will fall onto the first conveyor belt 104, and driven by the motor 107, the raw materials are transported to the raw material box 103 and the next cycle is carried out again.

[0025] The utility model can convey materials to the entrance of the hammer mill through the conveying structure 2, and can greatly improve the conveying capacity by arranging multiple groups of tipping buckets 202 on the second conveyor belt 201, and can knock and vibrate the tipping buckets 202 through the vibration structure 203 to avoid the raw materials from sticking to the inner wall after long-term use, thereby affecting the feeding efficiency. The raw materials can be screened by arranging a screen frame 111 on the side of the mounting frame 1 to avoid damage to the equipment when the raw materials are mixed with foreign matter. This structure greatly improves the practicality and safety of the feeding structure of the hammer mill. The first conveyor belt 104 of the utility model can collect the scattered raw materials during the feeding process and re-convey them to the raw material box 103, and can greatly improve the conveying capacity through the vertical plate 105. And the compression degree of the spring 207 can be further adjusted by the cooperation of the threaded rod 205 and the adjusting nut 208, thereby further adjusting the amplitude of the vibration, which can further improve the conveying and feeding effect of the feeding structure of the hammer mill.

[0026] See attached Figure 2 -Attached Figure 3 The conveying structure 2 includes a mounting plate 204 , which is fixedly arranged on the tipping bucket 202 , and a threaded rod 205 is movably arranged on the mounting plate 204 , and an extrusion block 206 is fixedly connected to the top of the threaded rod 205 , and a spring 207 is arranged between the extrusion block 206 and the mounting plate 204 .

[0027] In this embodiment, in order to prevent the raw materials from sticking to the inner wall after long-term use, a conveying structure 2 is provided on the tipping bucket 202. The side of the extrusion block 206 is an arc structure, so when the vibration rod 110 contacts the extrusion block 206, the extrusion block 206 moves inward along the threaded rod 205. When the tipping bucket 202 leaves the vibration structure 203, the extrusion block 206 returns to its original state under the action of the spring 207.

[0028] See attached Figure 2 -Attached Figure 3 The spring 207 is sleeved on the threaded rod 205 , and an adjusting nut 208 is also provided on the threaded rod 205 . The adjusting nut 208 is arranged on the outer side of the mounting plate 204 .

[0029] In this embodiment, in order to facilitate the adjustment of the tightness of the spring 207 and thus further adjust the vibration amplitude of the vibration structure 203 , an adjustment nut 208 is further provided on the threaded rod 205 .

[0030] See attached Figure 1 -Attached Figure 2 A motor 107 is provided at the bottom of the mounting frame 1 , and the motor 107 is connected to the lower roller 102 through a belt 108 .

[0031] In this embodiment, in order to drive the feeding structure to work, a motor 107 is provided at the bottom of the mounting frame 1, and drives the lower roller 102 to rotate through a belt 108.

[0032] See attached Figure 2 -Attached Figure 3 A horizontal frame 109 is arranged on the side of the mounting frame 1 , a vibration rod 110 is arranged on the inner side of the horizontal frame 109 , and the vibration rod 110 is arranged on the right side of the upper roller 101 .

[0033] In this embodiment, in order to improve the vibration effect, a vibration rod 110 is provided inside the cross frame 109. When the tipping bucket 202 moves to the position of the vibration rod 110, the extrusion block 206 on the vibration structure 203 just contacts the vibration rod 110 and generates vibration.

[0034] See attached Figure 1 -Attached Figure 2 A raw material box 103 is arranged on the left side of the mounting frame 1, and a plurality of walking wheels 106 are arranged on the bottom of the mounting frame 1.
