Description

Technical Field

[0001] The utility model relates to the technical field of material yard structures, in particular to a C-type closed material yard. Background Art

[0002] In recent years, the application of C-type mechanized material yards in domestic mining, ports, metallurgy, building materials and other industries has gradually increased. It is currently one of the main storage methods for bulk materials. It has the characteristics of many engineering application examples, flexible process layout, mature process technology, high reliability of process equipment, and mature civil engineering and other public supporting facilities.

[0003] However, this type of material yard uses a separate stacking and unloading operation mode. When stacking, the material falls directly from the unloading equipment into the ground surface pool with free fall. The maximum drop is close to 30m, and the minimum is about 9m. First, some materials are more broken, which is not conducive to production and increases costs. Second, the dust is particularly strong, especially when the moisture content of the material is low, which is not suitable for dry material storage. This C-type material yard layout cannot use centralized bag dust collectors for dust removal. It can only be used to suppress dust by dry fog and fog cannons, but the effect is not ideal. The superposition of dust, water mist and high temperature is not friendly to the on-site working environment, and environmental protection treatment is difficult. Utility Model Content

[0004] The main purpose of the utility model is to provide a C-shaped closed material yard, aiming to reduce the drop of materials directly falling to the ground during unloading.

[0005] To achieve the above-mentioned purpose, the utility model provides a C-type closed material yard, including a closed greenhouse grid frame and a cantilever unloading trolley, a unloading chute, a stacking trolley, a semi-gantry scraper reclaimer, a material yard input belt conveyor, a material yard output belt conveyor and a support frame installed inside the closed greenhouse grid frame, wherein:

[0006] The cantilever unloading trolley is installed above the supporting frame, and the cantilever unloading trolley transfers the materials input by the material yard input belt conveyor to the unloading chute.

The buffer bucket is located below the unloading chute, and the output end of the semi-gantry scraper reclaimer is located above the input end of the material yard output belt conveyor to transmit materials.

[0007] Preferably, the C-type closed material yard also includes a longitudinal partition wall of the material yard and a transverse partition wall of the material pool located inside the closed greenhouse grid, and the support frame is fixedly connected to the top of the longitudinal partition wall of the material yard and the transverse partition wall of the material pool.

[0008] Preferably, the C-type closed material yard also includes a ground track for supporting the movement of the semi-gantry scraper reclaimer and the stacking trolley, and the bottom end rollers of the semi-gantry scraper reclaimer and the stacking trolley are both installed on the ground track.

[0009] Preferably, a top track is installed on the support frame, and the upper rollers of the semi-gantry scraper reclaimer and the stacking trolley are installed on the top track to move relative to the support frame.

[0010] Preferably, a discharge walking track is installed on the support frame, and the cantilever discharge trolley is installed on the discharge walking track so as to be movable relative to the support frame, and the discharge walking track is located above the top track.

[0011] Preferably, the length of the discharge chute is adjustable.

[0012] Preferably, the telescopic swing chute is telescopic in length and can swing inside the material yard.

[0023] Reference Figure 1 and Figure 2 In this preferred embodiment, a C-type closed material yard includes a closed greenhouse grid frame 1 and a cantilever unloading trolley 2, a unloading chute 3, a stacking trolley 5, a semi-gantry scraper reclaimer 6, a material yard input belt conveyor 4, a material yard output belt conveyor 7 and a support frame 8 installed inside the closed greenhouse grid frame 1, wherein,

[0024] The cantilever unloading trolley 2 is installed above the supporting frame 8. The cantilever unloading trolley 2 transfers the materials input by the material yard input belt conveyor 4 to the unloading chute 3. The stacking trolley 5 includes a gantry located below the unloading chute 3, a buffer bucket installed on the gantry, and a telescopic swing chute. The buffer bucket is located below the unloading chute 3 to receive the materials inside the unloading chute 3. The output end of the semi-gantry scraper reclaimer 6 is located above the input end of the material yard output belt conveyor 7 to transmit materials.

[0025] The material field output tape machine 7 system is arranged on both sides of the closed greenhouse grid frame 1. The semi-gantry scraper reclaimer 6 includes an upper cross-type gantry and a reclaiming system. The closed greenhouse grid frame 1 is fully enclosed by a color plate. For other embodiments, the side bottom can also be enclosed by a windshield with an opening rate at a certain height, or it can be enclosed by a brick wall, or it can be fully enclosed by a membrane material. The cantilever unloading trolley 2 adopts a common structure in the prior art.

[0026] Furthermore, the C-type closed material field also includes a material field longitudinal partition wall 9 and a material pool transverse partition wall 10 located inside the closed greenhouse grid 1, and the support frame 8 is fixedly connected to the top of the material field longitudinal partition wall 9 and the material pool transverse partition wall 10. The support frame 8 can adopt a T-shaped structure.

[0027] Specifically, in this embodiment, the C-type closed material yard also includes a ground track for supporting the semi-gantry scraper reclaimer 6 and the stockpiling trolley 5 to travel, and the bottom rollers of the semi-gantry scraper reclaimer 6 and the stockpiling trolley 5 are both installed on the ground track. In other words, the semi-gantry scraper reclaimer 6 and the stockpiling trolley 5 share a ground track.

[0028] Specifically, in this embodiment, a top track is installed on the support frame 8, and the upper rollers of the semi-gantry scraper reclaimer 6 and the stacking trolley 5 are installed on the top track to move relative to the support frame 8. A discharge walking track is installed on the support frame 8, and the cantilever discharge trolley 2 is installed on the discharge walking track to be able to move relative to the support frame 8, and the discharge walking track is located above the top track.

[0029] In this embodiment, the length of the discharge chute 3 is adjustable. The discharge chute 3 can be extended and retracted by a certain distance. The discharge chute 3 is installed on the cantilever discharge trolley 2 and can feed the materials to the stacking trolley 5.

[0030] Furthermore, the length of the telescopic swing chute is telescopic and can swing inside the material yard, so that the swing angle of the telescopic swing chute can be flexibly adjusted according to the height of the pile of materials, thereby adjusting the direction of unloading.

[0031] Specifically, the telescopic swing chute is swung by the winch. The cantilever unloading trolley 2, the unloading chute 3 and the stacking trolley 5 need to be used in a synchronous manner when the materials are input and stored.

[0032] In this embodiment, each half-gantry scraper reclaimer 6 is correspondingly provided with two stockpiling trolleys 5. The C-type closed material yard is provided with two half-gantry scraper reclaimers 6 and four stockpiling trolleys 5.

[0033] Furthermore, the unloading chute 3 is sealed and connected with the buffer bucket to realize the closed unloading of the cantilever unloading trolley 2 and the stacking trolley 5, and the closed unloading further reduces the head generated during unloading. The closed greenhouse grid 1 is also equipped with auxiliary systems such as equipment power supply and lighting system, dust suppression system, fire protection system, heating and ventilation, water supply and drainage, etc.

[0034] This C-type closed material yard includes the following steps when realizing material stacking and taking:

[0035] 1) First, according to the material pre-storage position instruction, the cantilever unloading trolley 2 of the unloading device on the support frame 8 first moves to the designated storage position according to the position relationship between each other, the material input process flow is switched to the designated material input belt conveyor to complete the pre-material input preparation work, and the material yard input belt conveyor 4 starts running.

[0036] 2) Then, the materials to be stored outside the yard are transported by the designated material yard input belt conveyor 4, and the materials transported by the material yard input belt conveyor enter the cantilever unloading trolley 2, and then sent to the buffer bucket of the stacking trolley 5 through the unloading chute 3, and stacked into the material pool through the telescopic swing chute set above it. The cantilever unloading trolley 2 and the stacking trolley 5 are used synchronously when the materials are input and stored, and they move back and forth in the longitudinal direction to store the materials at the designated storage position. After the materials are stacked to a certain height, the telescopic swing chute is lifted, and when the stacking trolley 5 reaches the highest point that can be stacked, it needs to be staggered with the cantilever unloading trolley 2, and the cantilever unloading trolley 2 and the lifting unloading chute 3 further stack the materials.

[0037] 3) According to the production requirements of the user, when a certain material needs to be taken out, the semi-gantry scraper reclaimer in the material yard moves to the designated position of the material yard. At the same time, the scraper of the scraper reclaimer completes the material preparation work before scraping the material.

[0038] 4) Finally, as the material is continuously scraped by the semi-gantry scraper reclaimer 6 to the material yard output belt conveyor 7, the material pile height begins to decrease, and the elevation angle of the scraper changes with the change of the material pile height. The semi-gantry scraper reclaimer 6 completes the entire reclaiming process by moving back and forth along the longitudinal direction of the material yard.

[0039] from Figure 2 It can be seen that the use of a C-type closed material yard can avoid the cross-operation interference problem that exists when the stacking device and the reclaiming device are located on the same working surface. However, when the cantilever unloading trolley 2 and the semi-gantry scraper reclaimer 6 need to be misaligned, the stacking trolley 5 needs to be switched to match them.

[0040] The C-type closed material yard proposed in this embodiment is provided with a stacking trolley 5 for stacking materials, so as to avoid directly putting materials into the material pile, and can effectively reduce a large amount of dust and material crushing caused by the belt conveyor directly unloading the incoming materials into the material yard, which has a very good effect of environmental protection and reducing production costs. In addition, in this C-type closed material yard, each unloading equipment, stacking equipment, and material taking equipment are separated into a single body and can operate at the same time. This C-type closed material yard has the advantages of simple structure, stable and reliable operation, and easy implementation.

[0041] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
