Description
Technical Field
[0001] The utility model belongs to the technical field of scraper conveyors, and particularly relates to a bottom-discharge scraper conveyor. Background Art
[0002] At present, most of the shotcreting processes in domestic coal mines are dry shotcreting processes; dry shotcreting causes a large amount of dust and a large amount of rebound during the spraying process, and the quality of the concrete is unstable; the wet shotcreting process is gradually popularized in coal mines. Compared with the dry shotcreting process, the wet shotcreting process has the advantages of low dust concentration in the construction area, elimination of the harm to the health of workers, small rebound rate, and stable spraying quality.
[0003] Although there are wet shotcreting process equipment in coal mines, due to factors such as the narrow space in the roadway, a large amount of concrete raw materials such as sand, gravel, and cement cannot be stored. For the above reasons, there are disadvantages such as slow construction progress and low efficiency. In view of the above deficiencies, multiple bins are arranged in the roadway to store concrete raw materials such as sand and gravel and cement, and then concrete is prepared and transported over a long distance through a drag pump.
[0004] Due to the arrangement of multiple bins and the distribution of raw materials during the feeding process of the bins, when the existing scraper conveyor is used to transport materials into the bins, after one bin is filled with materials, it is necessary to move the scraper conveyor or set up multiple scraper conveyors to meet the material transportation requirements of multiple different bins. The scraper conveyor is large in volume and troublesome to move, seriously affecting the work efficiency. Summary of the Invention
[0005] The utility model provides a bottom-discharge scraper conveyor to solve the problem that at present, only by moving the scraper conveyor or setting up multiple scraper conveyors can multi-point feeding be realized, which affects the transportation efficiency. By opening a plurality of feeding holes on the middle plate of the scraper conveyor and adjusting the opening and closing of the feeding holes through a push-pull plate, the adjustment of feeding at different positions can be realized, and the structure is simple.
[0006] In order to achieve the above object, the technical solution of the utility model is as follows:
[0007] A bottom-unloading scraper conveyor includes trough sides and a middle plate. The middle plate is fixedly arranged between two trough sides. A plurality of blanking mechanisms are arranged on the middle plate along its conveying direction. The blanking mechanism includes a blanking hole, a draw plate, a support plate, and a sliding member. A blanking hole is formed in the middle plate. A support plate is fixedly arranged on one side of a trough side away from the middle plate. A draw plate is slidably arranged above the support plate. The sliding member includes two oppositely arranged sliding blocks. The two sliding blocks are respectively located at both ends of the blanking hole. The two sliding blocks are fixedly arranged on the lower side of the middle plate, and sliding grooves are formed on their opposite sides. One end of the draw plate passes through the corresponding trough side and is slidably arranged between the two sliding grooves. By sliding the draw plate in the sliding grooves, the opening and closing of the corresponding blanking hole are adjusted, and thus the blanking position of the scraper conveyor is adjusted.
[0008] Preferably, a rib plate is fixedly arranged below the support plate. One end of the rib plate is fixedly connected to the trough side, and the supporting effect of the support plate is strengthened by the rib plate.
[0009] Preferably, the cross section of the trough side is in the shape of "Σ".
[0010] Preferably, limit holes are formed at the four corners of the support plate. Positioning holes matching the limit holes are formed at one end of the draw plate away from the corresponding blanking hole. By passing bolts through the positioning holes and the corresponding limit holes, the draw plate is fixed when the corresponding blanking hole is opened or closed.
[0011] Preferably, a handle is fixedly arranged at one end of the draw plate away from the corresponding blanking hole, and the draw plate is slid by pulling the handle.
[0012] By the above technical solutions, the beneficial effects of the present utility model are as follows:
[0013] By arranging a plurality of blanking holes on the middle plate of the scraper conveyor and adjusting the opening and closing of the corresponding blanking holes by sliding the draw plate, multi-point blanking of the scraper conveyor is realized. Without moving the scraper conveyor, the material conveying work of a single scraper conveyor corresponding to multiple bins or blanking positions can be achieved. Description of the Drawings

Specific embodiments
[0021] The present utility model will be further described below in conjunction with the drawings and specific embodiments:
[0022] As Figures 1 to 6 shown, this embodiment provides a bottom-discharge scraper conveyor, including a trough side 1 and a middle plate 2. The cross-section of the trough side 1 is in the shape of "Σ". The middle plate 2 is fixedly arranged between two trough sides 1. Materials are conveyed on the middle plate 2. A plurality of blanking mechanisms are arranged on the middle plate 2 along its conveying direction. Each blanking mechanism includes a blanking hole 3, a pull-out plate 4, a support plate 5 and a sliding member. A blanking hole 3 is opened on the middle plate 2. A plurality of blanking holes 3 are arranged along the extension direction of the middle plate 2. A support plate 5 is fixedly arranged on one side of a trough side 1 away from the middle plate 2. The support plate 5 is welded to the trough side 1. A rib plate 9 is fixedly arranged below the support plate 5. One end of the rib plate 9 is fixedly connected to the trough side 1. The rib plate 9 is welded to the support plate 5 and the trough side 1. The connection strength of the support plate 5 is ensured by the rib plate 9. A pull-out plate 4 is slidably arranged above the support plate 5. As Figure 4 shown, the sliding member includes two oppositely arranged sliding blocks 6. The two sliding blocks 6 are respectively located at both ends of the blanking hole 3. The two sliding blocks 6 are both fixedly arranged on the lower side of the middle plate 2, and sliding grooves are opened on their opposite sides. One end of the pull-out plate 4 passes through the corresponding trough side 1 and is slidably arranged between the two sliding grooves. The pull-out plate 4 is limited and slidably guided through the sliding grooves. The opening and closing of the blanking hole 3 are realized by sliding the pull-out plate 4.
[0023] A handle 7 is fixedly arranged at one end of the pull-out plate 4 away from the corresponding blanking hole 3. The pull-out plate 4 can be conveniently pulled through the handle 7 to adjust the opening and closing of the corresponding blanking hole 3.
[0024] Limit holes 8 are opened at the four corners of the support plate 5. Positioning holes 10 matching the limit holes 8 are opened at one end of the pull-out plate 4 away from the corresponding blanking hole 3. The positioning holes 10 are provided with two. When the blanking hole 2 is closed, as Figure 5As shown, the two positioning holes 10 on the draw plate 4 respectively correspond up and down with the two limiting holes 8 at one end of the support plate 5 close to the trough side 1. Thus, the draw plate 4 can be fixed by inserting bolts into the correspondingly positioned upper and lower positioning holes 10 and limiting holes 8. When the blanking hole 3 is opened, as Figure 6 As shown, the two positioning holes 10 on the draw plate 4 respectively correspond up and down with the two limiting holes 8 at one end of the support plate 5 away from the trough side 1. Thus, the draw plate 4 can be fixed by inserting bolts into the correspondingly positioned upper and lower positioning holes 10 and limiting holes 8, thereby realizing the fixation of the draw plate 4 and preventing the draw plate 4 from sliding when no operation is being performed.
[0025] During use, as Figure 2 As shown, when conveying materials to multiple bins by means of a bottom-unloading scraper conveyor of the present utility model, the draw plate 4 above the corresponding bin is slid by the handle 7 to open the blanking hole 3 above the corresponding bin. The materials conveyed on the middle plate 2 fall into the lower bin through the opened blanking hole 3 during the conveying process, thereby realizing the conveyance of materials to this bin. After the materials in this bin are filled, the corresponding blanking hole 3 above this bin is closed, and the corresponding blanking hole 3 above the next bin is opened to feed the next bin.
[0026] The above-described embodiments are only the preferred embodiments of the present utility model and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present utility model patent shall be included within the scope of the patent application of the present utility model.
