Description

Technical Field

[0001] The utility model relates to the technical field of vibrating feeding equipment, in particular to a vibrating feeder with a uniform feeding and stable structure. Background Art

[0002] A vibrating feeder, also known as a vibrating feeder, is a commonly used material conveying and feeding device, widely used in industries such as mining and coal mining. Vibrating feeders use vibration to transport materials from a storage bin or hopper to the next processing device or system. The excitation force generated by the vibrating motor causes the vibrating body to continuously vibrate, pushing the material into the conveyor trough, achieving continuous material conveyance.

[0003] In ore dressing, vibrating feeding equipment is often used to evenly transport the ore to be beneficiated into the dressing equipment. For example, a search revealed a patent publication numbered CN219751269U, which provides a uniformly distributed high-frequency vibrating feeder. The feeder includes a receiving bin with support columns arranged on its sides, distributed at the corners of the bin. A crossbeam is fixed to the top of the support columns, and a feed bin is fixed to the middle of the crossbeam. The feed structure includes a left frame, a left plate fixed to the left side of the left frame, a middle plate fixed below the left plate, a vibrator mounted on the side wall of the middle plate, a left pull block fixed to the left side of the left plate, a left hanging block fixed to the left side of the crossbeam, a left tension spring connecting the left pull block and the left hanging block, a right pull arm fixed to the right side of the left frame, and a right hanging block corresponding to the right pull arm fixed to the side of the crossbeam. The high-frequency vibration of the vibrator facilitates the uniform distribution of the stones that fall into the frame, facilitating uniform feeding and distribution of the stones, making operation simpler and more efficient.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example: Reference Figure 1-5 The vibrating feeder shown has a stable structure for uniform feeding, comprising a feeding box 1 with a feed port 101 and a removal port 102 respectively provided at the upper and lower ends, a feeding plate 2 provided on the inner side of the feeding box 1, the feeding plate 2 is tilted downward toward the side of the removal port 102, and a vibrator 3 is installed at the bottom of the feeding plate 2.

[0030] Among them, a dispersion mechanism is provided on the upper side of the feeding plate 2, and the dispersion mechanism includes a reciprocating drive assembly, a movable plate 4 and a plurality of first dispersion columns 5. The length direction of the movable plate 4 is arranged toward the unloading direction of the feeding plate 2. The reciprocating drive assembly is connected between the feeding box 1 and the movable plate 4 to drive the movable plate 4 to move horizontally back and forth perpendicular to the unloading direction of the feeding plate 2. A plurality of first dispersion columns 5 are fixed at equal distances at the lower end of the movable plate 4 along the length direction of the movable plate 4 to horizontally disperse the stones rolling down from top to bottom on the feeding plate 2, so as to feed the materials more stably and evenly.

[0031] Regarding the reciprocating drive assembly, specifically, the reciprocating drive assembly includes a drive motor 6, a reciprocating threaded screw 7 and a guide rod 8. The drive motor 6 is fixed to the side end of the feed box 1, and the reciprocating threaded screw 7 is rotatably installed on the feed box 1, and one end of the reciprocating threaded screw 7 is fixed to the output end of the drive motor 6. A reciprocating shaft sleeve that is compatible with the reciprocating threaded screw 7 is installed on the movable plate 4, the guide rod 8 is fixed to the inner side of the feed box 1, and the movable plate 4 is slidably sleeved on the outer side of the guide rod 8.

[0032] Among them, a sorting screen 9 is provided on the upper side of the dispersing mechanism, and the sorting screen 9 is installed on the feeding box 1. The feed port 101 and the removal port 102 are provided on the same side of the feeding box 1. The sorting screen 9 is tilted downward toward the side away from the feed port 101. The feeding box 1 is provided with a feeding port 103 on the side of the sorting screen 9 that is tilted downward. The set sorting screen 9 can screen the stones, remove stones with too large particle size, and further improve the uniformity of the feeding.

[0033] Taking into account the problem of clogging of the sieve holes on the sorting screen 9, a plurality of dredging components 11 are installed on the upper end of the movable plate 4 through the support frame 10. The plurality of dredging components 11 are adapted to the sieve holes on the sorting screen 9. Specifically, the dredging component 11 includes a fixed sleeve 111, an elastic member 112 and a dredging block 113. The fixed sleeve 111 is fixed to the support frame 10. The dredging block 113 is slidably sleeved on the inner side of the fixed sleeve 111, and the dredging block 113 is connected to the inner side of the fixed sleeve 111 through the elastic member 112. The dredging block 113 is adapted to the sieve holes on the sorting screen 9, and the end of the dredging block 113 in contact with the sorting screen 9 is provided with a chamfer.

[0034] During the reciprocating movement of the dredging component 11 along with the movable plate 4 , the sieve holes can be dredged by utilizing the dredging block 113 in cooperation with the elastic member 112 , thereby realizing the integrated dispersion and dredging of the above-mentioned dispersion mechanism.

[0035] In order to further improve the dispersion effect of ore and stone, a guide plate 12 parallel to the sorting screen 9 is provided on the lower side thereof.

[0036] Furthermore, a plurality of second dispersion columns 14 are fixed at equal intervals along the length direction of the support frame 10 near the end face of the movable plate 4. The second dispersion columns 14 can pre-disperse the stones falling onto the guide plate 12 in the horizontal direction as the movable plate 4 moves back and forth, thereby reducing the dispersion pressure of the first dispersion column 5 on the stones.

[0037] The working principle of the utility model is as follows: ore and stone are fed into the feed port 101, and the stone is screened by the provided sorting screen 9 to remove the stone with too large a particle size. The stone that meets the feed particle size falls from the screen hole onto the guide plate 12, and is then concentratedly guided to the inclined top of the feed plate 2 by the guide plate 12. The reciprocating drive assembly drives the movable plate 4 to move horizontally back and forth perpendicular to the feeding direction of the feed plate 2, and drives a plurality of first dispersion columns 5 to horizontally disperse the stone rolling down from the top to the bottom of the feed plate 2, thereby achieving uniform feeding.

[0038] Among them, the second dispersion column 14 can pre-disperse the stones that fall onto the material guide plate 12 in the horizontal direction as the movable plate 4 moves back and forth, thereby reducing the dispersion pressure of the first dispersion column 5 on the stones; and in the process of the dredging component 11 moving back and forth with the movable plate 4, the dredging block 113 is used to cooperate with the elastic member 112 to dredge the sieve holes, thereby realizing the integrated dispersion and dredging of the above-mentioned dispersion mechanism.
