Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stone processing equipment, in particular to an adjustable stone processing feeding device. Background Art
[0002] In the process of processing building materials into artificial sand and gravel aggregates for building materials, the raw stone materials after mining are transported to the coarse crushing workshop by transport vehicles for preliminary crushing. Since the particle sizes of raw stone materials vary, it is impossible to classify and control them from the source. Therefore, the stones loaded by the transport vehicles are sometimes larger in size and sometimes smaller in size. In order to ensure that the stones can pass through the feed port of the crusher smoothly, the size of the feed port is generally larger to accommodate stones of various sizes entering the crusher processing equipment.
[0003] The existing feeding device has the following problems: when the stone is finely crushed, the finely crushed stone often enters the crusher's feed port at once, stays in the crusher for a very short time, and then falls from the discharge port to the belt conveyor below. At this time, because the running speed of the belt conveyor cannot keep up with the feeding speed, a large amount of fine stone falls in a short period of time, pressing the belt conveyor and causing the equipment to stop, and production cannot continue at this time. If the feed port of the crusher is simply reduced, it cannot meet the requirements of large-diameter stone entering the processing equipment.
[0004] In summary, it is necessary to develop and design an adjustable stone processing feeding device to solve the above-mentioned technical problems. Utility Model Content
[0005] The utility model aims to provide an adjustable stone processing feeding device, which can not only feed large-diameter stones normally, but also provide blocking feeding for small-diameter crushed stones, so as to avoid equipment failure caused by small-diameter crushed stones entering the crusher below too quickly and forming a large amount of material discharge in an instant.
[0006] The technical solution adopted by the utility model is: an adjustable stone processing feeding device, including a vibrating feeder, a stone hopper is installed on the upper rear of the vibrating feeder, and an adjustable material blocking assembly is installed on the front of the vibrating feeder; the vibrating feeder includes a base frame and a rear bracket is provided at the rear of the base frame and a front bracket is provided at the front, a vibrating hopper is provided on the upper part of the base frame, side bases are installed on both sides of the front of the vibrating hopper, a rear spring is installed between the rear of the vibrating hopper and the rear bracket, a front spring is installed between the side base and the front bracket, and also includes a vibration assembly; a notch is provided at the front bottom of the vibrating hopper, and the adjustable material blocking assembly includes an axle seat installed on the side of the front end of the vibrating hopper and a rotating shaft installed on the axle seat, a material blocking plate suspended below is installed on the rotating shaft, and a counterweight block is detachably installed on the outer side of the material blocking plate.
[0007] Preferably, a threaded rod is provided on the outer side of the material blocking plate, and the counterweight block is mounted on the threaded rod and locked with a lock nut.
[0008] Preferably, a wear-resistant plate is fixedly mounted on the inner side wall of the material blocking plate, and the wear-resistant plate covers the inner material-facing surface of the material blocking plate.
[0009] Preferably, the top and front of the stone hopper are open, the inner cavity of the stone hopper gradually narrows from top to bottom and forms a long strip-shaped drop opening at the bottom.
[0010] Preferably, the stone hopper is fixed on the top of a hopper frame using a hopper bracket, the bottom of the hopper frame is fixedly connected to the base frame, an inner hopper connecting beam is installed between the two side walls of the stone hopper, and an outer hopper reinforcing rib is installed on the outer wall of the stone hopper.

[0013] Preferably, a vibrating hopper inner wear-resistant plate is paved on the bottom wall of the vibrating hopper and the inner surface of the side wall.
[0014] The advantages and positive effects of the utility model are:
[0015] The utility model provides an adjustable stone processing feeding device. Compared with the existing stone processing feeding device, the main part of the stone processing feeding device of the utility model is a vibrating feeder. By installing an adjustable material blocking component at the front of the vibrating feeder, the technical effect of blocking the stone is achieved. For small-diameter stone, since the crushed stone is relatively light, the pushing effect on the adjustable material blocking component under the action of vibration is relatively small, so the small-diameter crushed stone can only be discharged outward from the gap between the end of the vibrating hopper and the adjustable material blocking component, realizing controllable discharge instead of centralized discharge. For large-diameter stone, since the stone is relatively heavy, the pushing effect on the adjustable material blocking component under the action of vibration is relatively large, so the large-diameter stone can push the blocking plate outward and fall normally. Therefore, the feeding device of the utility model can not only feed large-size stones normally, but also provide blocking feeding for small-size crushed stones, thereby preventing small-size crushed stones from entering the crusher below too quickly and causing equipment failure due to instantaneous large-scale discharge.
[0016] The adjustable stone processing feeding device of the utility model has an adjustable material blocking component which is composed of an axle seat, a rotating shaft, a material blocking plate and a detachable counterweight block. The material blocking plate can flexibly swing back and forth with the rotating shaft as the center. The swing characteristics of the material blocking plate can be adjusted by replacing the counterweight block to adapt to different working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.
[0024] See also Figure 1 The adjustable stone processing feeding device of the utility model includes a vibrating feeder, a stone hopper 7 is installed above the rear of the vibrating feeder, and an adjustable material blocking component is installed at the front of the vibrating feeder. During operation, the stone transport vehicle puts the stone into the stone hopper 7, and then the stone falls downward into the vibrating feeder and moves forward under the action of vibration, and finally passes through the adjustable material blocking component and is discharged from the end of the vibrating feeder, and falls downward into the feed port of the crusher equipment (such as a jaw crusher). The adjustable material blocking component provides a material blocking effect on the stone, while meeting the normal feeding of large-diameter stones, solving the problem of concentrated falling of small-diameter stones.
[0025] See also Figure 3 , we can see that:
[0026] The vibrating feeder includes a base frame 1, and a rear bracket 3 is provided at the rear of the base frame 1, and a front bracket 13 is provided at the front. A vibrating hopper 8 is provided above the base frame 1, and side bases 9 are installed on both sides of the front of the vibrating hopper 8. A rear spring 4 is installed between the rear of the vibrating hopper 8 and the rear bracket 3, and a front spring 12 is installed between the side base 9 and the front bracket 13. It can be seen that the vibrating hopper 8 is supported by the rear spring 4 and the front spring 12 in a floating manner.
[0027] It also includes a vibration assembly, as shown in the figure, the vibration assembly includes a vibrator 2 installed at the rear bottom of the vibrating hopper 8 and a driving mechanism that outputs a driving effect to the vibrator 2. The driving mechanism includes a shock-absorbing base 11 installed on the base frame 1, a driving motor 10 is installed on the shock-absorbing base 11, and pulleys are installed on the output shaft of the driving motor 10 and the input shaft of the vibrator 2, and the pulleys are connected by a transmission belt 22. The purpose of installing the driving motor 10 on the shock-absorbing base 11 is to isolate the driving motor 10 from the vibration effect and prevent the operation of the driving motor 10 from being adversely affected.
[0028] In this embodiment, the length of the bottom wall of the vibrating hopper 8 is shorter than the length of the side wall, and a plurality of slag-dropping beams 21 are installed in parallel in the front of the bottom wall of the vibrating hopper 8. The length direction of the slag-dropping beams 21 is parallel to the length direction of the vibrating hopper 8, and a slag-dropping channel is formed between adjacent slag-dropping beams 21. The purpose of setting a slag-dropping area composed of a plurality of slag-dropping beams 21 in the front of the vibrating hopper 8 is to allow stones and soil materials with a particle size smaller than the distance between adjacent slag-dropping beams 21 to pass through the slag-dropping area and fall to the ground below, thereby preventing these finely crushed components (usually approximately in powder form) from entering the crusher equipment.
[0029] In this embodiment, a vibration hopper inner wear plate 20 is paved on the bottom wall and the inner surface of the side wall of the vibration hopper 8. The function of paving the vibration hopper inner wear plate 20 is to improve the wear resistance of the vibration hopper 8 and to improve the service life of the vibration hopper 8.
[0030] See also Figure 2 , we can see that:
[0031] The top and front of the stone hopper 7 are open, and the inner cavity of the stone hopper 7 gradually narrows from top to bottom and forms a long strip-shaped drop opening 18 at the bottom. The stone injected into the stone hopper 7 by the transport vehicle enters the rear part of the vibrating hopper 8 through the long strip-shaped drop opening 18 downward.
[0032] In this embodiment, the stone hopper 7 is fixed on the top of a hopper frame 5 by a hopper bracket 6, and the bottom of the hopper frame 5 is fixedly connected to the base frame 1, so that the vibration generated by the vibration assembly is transmitted to the stone hopper 7 through the base frame 1, the hopper frame 5 and the hopper bracket 6, that is, the stone hopper 7 is also subjected to a certain vibration, which is conducive to the downward discharge of stones. In this embodiment, an inner hopper connecting beam 16 is installed between the two side walls of the stone hopper 7, and an outer hopper reinforcing rib 19 is installed on the outer wall of the stone hopper 7. The purpose of providing the inner hopper connecting beam 16 and the outer hopper reinforcing rib 19 is to improve the overall structural strength of the stone hopper 7 and enhance the stone hopper 7 to resist the impact of stones.
[0033] In this embodiment, a stone hopper inner wear plate 17 is paved on the inner wall of the stone hopper 7. The function of paving the stone hopper inner wear plate 17 is to improve the wear resistance of the stone hopper 7 and to improve the service life of the stone hopper 7.
[0034] See also Figure 4 , we can see that:
[0035] A notch 23 is provided at the front bottom of the vibrating hopper 8, and the adjustable material blocking assembly is installed above the notch 23. The notch 23 is formed in the following manner: a portion of the front end of the side plate of the vibrating hopper 8 is cut off, and the front end of each slag beam 21 does not extend into the range of the notch 23.
[0036] As shown in the figure, the adjustable material blocking assembly includes an axle seat 24 installed at the front end side of the vibrating hopper 8 and a rotating shaft 14 installed on the axle seat 24, a material blocking plate 15 suspended below is installed on the rotating shaft 14, and a counterweight 26 is detachably installed on the outer side of the material blocking plate 15. The material blocking plate 15 is freely suspended below the rotating shaft 14, and since the rotating shaft 14 can flexibly rotate in the axle seat 24, the material blocking plate 15 can flexibly swing back and forth. As shown in the figure, the middle and lower part of the material blocking plate 15 is located within the range of the notch 23, so a material drop channel is formed between the front part of the vibrating hopper 8 and the material blocking plate 15.
[0037] In this embodiment, a threaded rod 28 is provided on the outer side of the material blocking plate 15, and a counterweight block 26 is mounted on the threaded rod 28 and locked with a lock nut 27, so that the counterweight block 26 can be replaced as needed. When the counterweight blocks 26 of different weights are replaced, the swing characteristics of the material blocking plate 15 change.
[0038] In this embodiment, a wear-resistant plate 25 is fixedly mounted on the inner side wall of the material blocking plate 15, and the wear-resistant plate 25 covers the inner material-facing surface of the material blocking plate 15. The purpose of setting the wear-resistant plate 25 is to increase the service life of the material blocking plate 15. When the wear-resistant plate 25 is excessively worn, the wear-resistant plate 25 is replaced.
[0039] Running process:
[0040] The stone transport vehicle dumps the stone into the stone hopper 7, and the stone gradually moves downward under the certain vibration of the stone hopper 7, and is finally discharged from the long strip drop opening 18 at the bottom and falls into the rear part of the vibrating hopper 8 below; it is worth noting that in this process, among the stones dumped into the stone hopper 7, there is a mutual squeezing effect between the large-size stones, so the dropping speed of the large-size stones is usually lower than that of the small-size stones, that is, under normal circumstances, the small-size stones in the stones fall into the vibrating hopper 8 first, and the large-size stones gradually pass through the drop opening 18 in a slow-release state under the vibration;
[0041] Under the action of vibration, when small-size stones are gradually transferred to the end of the vibrating hopper 8, the small-size stones have little pushing effect on the blocking plate 15, so the blocking plate 15 will not move. At this time, the small-size stones can only be discharged from the gap between the end of the vibrating hopper 8 and the blocking plate 15, achieving the effect of slow release. Therefore, the small-size stones will not fall in a concentrated manner, which solves the problem of equipment operation failure caused by concentrated falling in the working condition where the small-size stones in the prior art enter the crusher equipment in a concentrated manner and then fall on the belt conveyor below. Under the action of vibration, when the large-size stones are gradually transferred to the end of the vibrating hopper 8, the large-size stones have a greater pushing effect on the material blocking plate 15. Therefore, under the pushing effect of the large-size stones, the material blocking plate 15 and its accessories are pushed forward, and the bottom of the material blocking plate 15 moves forward. In this way, the gap for the discharge of stones that were originally not large enough is increased, and the large-size stones are discharged normally and fall into the vibrating hopper 8. After the large-size stones are discharged, the material blocking plate 15 swings back to its original position.
