[0002] The simplest screening equipment is a fixed screen, consisting of a fixed, stationary screen surface composed of numerous parallel bars. The screen can be mounted horizontally or tilted, and the material is screened by its own weight sliding down the screen surface. Although its capacity per unit area and screening efficiency are low, it is widely used in coal preparation plants due to its simple structure, lack of power consumption, lack of moving parts, low equipment cost, and easy maintenance.

[0003] After searching, the existing Chinese patent publication number is: CN 218637866 U, which provides a batching screening device for preparing cold-rammed paste. The patent controls the movement of one screen and staggers the two screens to adjust the size of the screen holes to screen aggregates of different sizes. The operation is simple and more convenient.

[0004] Although the above patent can adjust the size of the screen holes to screen aggregates of different sizes, the above-mentioned batching and screening device for cold rammed paste preparation still has the following problems: when the aggregates are fed into the filter screen through the feeding port, the aggregates will accumulate on the filter screen, and then during the later screening, it is not easy to disperse the accumulated aggregates, which will cause the aggregates to accumulate and move, resulting in incomplete screening, etc.

[0005] In view of the above problems, a batching screening device for cold rammed paste preparation is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0027] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0028] See also Figure 1-5The utility model provides a technical solution: a batching and screening device for preparing cold rammed paste, comprising a screening machine body 1 (the screening machine body 1 has the same working principle as that of the existing patent CN 218637866 U). A protective shell 4 is fixedly installed on the top of the screening machine body 1, a discharge port 20 is provided at the bottom of the protective shell 4, a hopper 2 is fixedly installed on the top of the protective shell 4, the hopper 2 is communicated with the interior of the protective shell 4, a driving motor 3 is fixedly installed on one side of the protective shell 4, a rotating shaft 12 is fixedly installed on the output end of the driving motor 3, a round roller 9 is fixedly sleeved on the surface of the rotating shaft 12, the round roller 9 is rotatably connected inside the protective shell 4, a storage trough 10 is provided on the surface of the round roller 9, and the storage trough 10 coincides with the discharge port 20.

[0029] Put the aggregate inside the hopper 2, start the drive motor 3, and make the drive motor 3 drive the rotating shaft 12 to rotate, and then drive the round roller 9 to rotate. When the storage trough 10 is facing upward, the aggregate inside the hopper 2 will enter the storage trough 10. Then, as the round roller 9 rotates, when the storage trough 10 turns one hundred and eighty degrees, the storage trough 10 will coincide with the discharge port 20, and then the aggregate inside the storage trough 10 will be dumped into the interior of the screening machine body 1, thereby realizing the quantitative addition of aggregate, facilitating the later screening, preventing the aggregate from accumulating on the screen inside the screening machine body 1, avoiding uneven screening in the later stage, and preventing uneven screening in the later stage caused by excessive discharge, thereby improving the screening effect.

[0030] A gear 11 is fixedly mounted on the rotating shaft 12, and a groove 13 is provided on the gear 11. A polygonal rod 8 is slidably connected to the interior of the screening machine body 1, and a tension spring 16 is movably sleeved on one end of the polygonal rod 8 extending to the outside of the screening machine body 1. The end of the tension spring 16 close to the screening machine body 1 is fixedly connected to the screening machine body 1, and the end of the tension spring 16 away from the screening machine body 1 is fixedly connected to the polygonal rod 8. A movable outer plate 5 is fixedly mounted on the end of the polygonal rod 8 extending to the interior of the screening machine body 1, and an inner scraper 7 is slidably connected to the interior of the movable outer plate 5. A bracket 15 is fixedly mounted on the top of the movable outer plate 5, and a rack 14 is fixedly mounted on the top of the bracket 15. The rack 14 is meshed with the gear 11.

[0031] When the rotating shaft 12 rotates, the rotating shaft 12 drives the gear 11 to rotate, and since the gear 11 is meshed with the rack 14, the rack 14 and the bracket 15 are driven to move, so that the movable outer plate 5 and the inner scraper 7 are moved, so that the polygonal rod 8 slides inside the screening machine body 1, and the tension spring 16 is stretched. When the aggregate inside the storage trough 10 is poured onto the screen inside the screening machine body 1, the storage trough 10 and the discharge port 20 are no longer coincident, the groove 13 and the rack 14 are no longer coincident, and the polygonal rod 8 is reset by the tension of the tension spring 16, so that the movable outer plate 5 and the inner scraper 7 are reset, and the aggregate on the screen inside the screening machine body 1 is flattened by the inner scraper 7, so that the aggregate is dispersed on the screen, the screening effect is improved, and the later screening is facilitated, and the accumulation of aggregate is prevented, resulting in incomplete screening in the later stage.

[0032] The movable outer plate 5 is internally rotatably connected with a threaded rod 17, the top of which is fixedly mounted with a handle 6, the threaded rod 17 is connected to the internal thread of the inner scraper 7, a limiting slide 18 is provided inside the movable outer plate 5, and the limiting slide 18 is internally slidably connected with a limiting block 19, and the limiting block 19 is fixedly connected to the inner scraper 7 at one end close to the inner scraper 7.

[0033] Turn the handle 6 to rotate the threaded rod 17, driving the inner scraper 7 to slide inside the movable outer plate 5, so that the limiting block 19 slides inside the limiting slide 18, and thus the inner scraper 7 slides inside the movable outer plate 5, making it easier for the inner scraper 7 to rise and fall and slide inside the movable outer plate 5, thereby facilitating the height adjustment of the inner scraper 7, thereby facilitating the adjustment of the leveling height of the aggregate, thereby facilitating the dispersion of the aggregate, and thereby expanding the scope of use of the device.

[0034] Working principle:

[0035] Put the aggregate inside the hopper 2, start the drive motor 3, and make the drive motor 3 drive the rotating shaft 12 to rotate, and then drive the round roller 9 to rotate. When the storage trough 10 is facing upward, the aggregate inside the hopper 2 will enter the storage trough 10. Then, as the round roller 9 rotates, when the storage trough 10 turns 180 degrees, the storage trough 10 will coincide with the discharge port 20, and then the aggregate inside the storage trough 10 will be dumped into the interior of the screening machine body 1, thereby realizing the quantitative addition of the aggregate. When the rotating shaft 12 rotates, the rotating shaft 12 drives the gear 11 to rotate, and then due to the gear 11 It engages with the rack 14, thereby driving the rack 14 and the bracket 15 to move, thereby moving the movable outer plate 5 and the inner scraper 7, causing the polygonal rod 8 to slide inside the screening machine body 1, and thereby stretching the tension spring 16. When the aggregate inside the storage trough 10 is poured onto the screen inside the screening machine body 1, the storage trough 10 and the discharge port 20 will no longer overlap, and the groove 13 and the rack 14 will no longer overlap, and the polygonal rod 8 will be reset by the tension of the tension spring 16, thereby resetting the movable outer plate 5 and the inner scraper 7, and then the aggregate on the screen inside the screening machine body 1 will be flattened by the inner scraper 7.
