Description

Technical Field

[0001] This utility model relates to a stone crushing technology, specifically a technology for conveying stones in a stone crusher. Background Technology

[0002] In the construction industry, stones can be crushed to form a variety of building materials. For example, they can be crushed to form various colored sands that can be used in the field of building decoration.

[0003] The crushing equipment used can be different types of crushers, such as impact crushers or jaw crushers, depending on the size of the stone or the particle size to be crushed. Multiple crushers can also be used in series to obtain the required particle size of gravel.

[0004] In conventional crushers, stones need to be continuously fed into the crusher's opening. Unloading directly from a vehicle's hopper into the opening is often difficult, resulting in too many stones spilling into the surrounding area. Manual feeding is difficult to automate. Existing technologies have begun using conveyor belts for transport; however, existing conveyor belt feeding methods have a technical problem: obstructions such as the support frames often exist below the sides of the conveyor structure. These frames hinder material feeding and discharging. During feeding, the rear of the vehicle's hopper can easily touch the frame, and the frame can also easily touch the crusher, causing stones to fall at the connection point. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, thereby providing a technology that facilitates matching vehicle unloading and adding stones into the crusher.

[0006] To achieve the above objectives, this utility model provides a pre-conveying structure for crushing stone, which includes a transmission platform and a drive assembly;

[0007] The transmission platform has a front end and a rear end, with a suspended structure below the front end and the rear end; the front end is used to receive stones, and the rear end is used to add stones into the crusher; the transmission platform has a front roller and a rear roller, and the front roller and the rear roller have conveyor belts.

[0008] The drive assembly is located in the middle and below the transmission platform. The drive assembly has a drive motor, a drive roller, a left support roller and a right support roller. The drive motor is connected to the drive roller. The conveyor belt is sleeved on the drive roller. The left support roller and the right support roller are respectively arranged on the upper two sides of the drive roller. The conveyor belt turns after passing the left support roller and then passes the rear roller. The conveyor belt turns after passing the right support roller and then passes the front roller.

[0009] Preferably, the drive assembly has a frame housing, inside which the drive roller, left support roller and right support roller are arranged, and the drive motor is arranged on one side of the frame housing; the bottom of the frame housing is provided with casters.

[0010] Preferably, the transmission platform includes a support motherboard, with embedded grooves in the middle of both sides of the support motherboard. Fixing bolts are provided in the embedded grooves, and the interior of the fixing bolts is set in the embedded grooves through embedded blocks. The upper part of the frame housing is tightened and fixed to the fixing bolts by fastening nuts.

[0011] Preferably, fixing bolts are also provided on both sides of the embedding groove, and the fixing bolts fix the fixing plate into the embedding groove, and the front side roller or the rear side roller is erected between the fixing plates at both ends.

[0012] Preferably, the two side plates of the frame housing have mounting slots, and a fixing screw is provided in the mounting slot. One end of the fixing screw abuts against the inner wall of the mounting slot. A detachable clip is also provided in the mounting slot. The engaging part of the clip is sleeved on the free end of the fixing screw. The upper and lower ends of the clip are fixed to the side plate by mounting screws. A support block is provided in the middle of the fixing screw. The support block fits into the middle of the mounting slot. The inner end of the support block is rotatably connected to the left support roller and the right support roller.

[0013] The beneficial effects of this utility model are as follows: by setting the drive component in the lower middle position of the conveyor platform, the lower part of the front and rear ends is a suspended structure. This way, when loading or unloading materials onto the conveyor belt or discharging materials from the conveyor belt to the downstream crusher, the drive component will not touch the frame support structure under the conveyor belt. This makes the cooperation between the two closer and avoids the problem of stones falling at the connection point. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1:

[0025] like Figure 1 and Figure 2 As shown, a pre-conveying structure for crushing stone in this embodiment includes a conveying platform 1 and a drive assembly 2:

[0026] like Figure 3As shown, the conveying platform 1 has a front end 11 and a rear end 12, with a suspended structure below the front end 11 and the rear end 12. The front end 11 is used to receive stones, and the rear end 12 is used to add stones into the crusher. The conveying platform 1 has a front roller 13 and a rear roller 14, with a conveyor belt 15 on the front roller 13 and the rear roller 14. In this structure, the front end 11 and the rear end 12 are both suspended structures without any supporting structure. Instead, they are supported in the middle. This allows the vehicle to approach the front end 11, for example, when dumping stones from a vehicle, part of the vehicle can come close to the front end 11, and even part of the structure can enter below the front end 11. This facilitates the transfer of the stone material to the front end 11 and into the conveying platform 1. Furthermore, the area below the rear end 12 is also a suspended structure. When the rear end 12 is engaged with the crusher 10 on the downstream side, the rear end 12 can be positioned directly above the top side of the opening 11 of the crusher 10. This allows the stones to enter the crusher more effectively without affecting the crusher 10.

[0027] The drive assembly 2 is located below the center of the transmission platform 1. The drive assembly 2 includes a drive motor 21, a drive roller 22, a left support roller 23, and a right support roller 24. The drive motor 21 is connected to the drive roller 22 and can be driven by a gearbox or mechanical conversion structure as described in the prior art. The conveyor belt 15 is fitted onto the drive roller 22. The left support roller 23 and right support roller 24 are respectively arranged on the upper sides of the drive roller 22. The conveyor belt 15 turns after passing the left support roller 23 and then passes the rear roller 14. The conveyor belt 15 turns after passing the right support roller 24 and then passes the front roller 13. Thus, the conveyor belt 15 forms a complete circular motion and is stably supported by the left support roller 23 and right support roller 24.

[0028] The drive assembly 2 is located in the lower middle part of the transmission platform 1. The drive roller 22 is located in the lower middle part, which makes the drive structure very stable. Compared with the single side, it has better stability. The overall weight of the drive motor 21 and drive roller 22 is relatively heavy and the center of gravity is low. This arrangement in the lower middle part makes the support of the entire structure more stable. The drive roller 22 provides rotational power to the conveyor belt 15 and is turned and conveyed through the left support roller 23 and the right support roller 24. It achieves circular transportation at the front end 11 and the rear end 12, which has good stability.

[0029] Example 2:

[0030] Preferably, in this embodiment, the drive assembly 2 has a frame housing 25 ( Figure 1The frame housing 25 contains the drive roller 22, the left support roller 23, and the right support roller 24. The drive motor 21 is located on one side of the frame housing 25. Casters 26 are located at the bottom of the frame housing 25. Figure 1 The movable wheels 26 facilitate the overall movement of the frame housing 25 and the entire structure transmission platform 1, allowing it to be moved in conjunction with the crusher 10, or moved to other locations for use and matching.

[0031] like Figure 4 and Figure 5 As shown, the transmission platform 1 includes a support motherboard 16. The support motherboard 16 has embedding grooves 17 on both sides of its center. Fixing bolts 18 are installed within the embedding grooves 17, and the interiors of the fixing bolts 18 are secured in the embedding grooves 17 via embedding blocks 19. The upper part of the rack housing 25 is tightened and fixed to the fixing bolts 18 by fastening nuts 20. In this way, the support motherboard 16 is fixedly connected to the rack housing 25 below, forming a stable support. Figure 4 The mounting plate 30 of the rack housing 25 is omitted. Figure 5 and Figure 6 The image shows the mounting and fixing of the rack housing 25 and the support plate 16.

[0032] Fixing bolts 18 are also provided on both sides of the embedding groove 17. The fixing bolts 18 fix the end plate 35 into the embedding groove 17. The front roller 13 or the rear roller 14 is erected between the end plates 35 at both ends to form a stable structure.

[0033] like Figure 6 As shown, the two side plates 27 of the frame housing 25 have mounting slots 28, and the side plates 27 have inner pressing plate portions 29. A fixing screw 31 is provided in the mounting slot 28, and the inner end of the fixing screw 31 is threaded onto the inner wall 281 of the mounting slot 28 (threaded hole installation). A detachable clip 32 is also provided in the mounting slot 28, and the engaging part of the clip 32 is fitted onto the free end (outer end) of the fixing screw 31. The upper and lower ends of the clip 32 are fixed to the side plate 27 (fixing plate 30) by mounting screws 33. The clip 32 presses and fixes the screw 31 to the inner pressing plate portion 29.

[0034] The fixing screw 31 has a support block 34 in its middle section. The support block 34 fits into the middle of the mounting slot 28. The inner end of the support block 34 is rotatably connected to the left support roller 23 and the right support roller 24. The fixing screw 31 and the support block 34 are threaded together, meaning that the fixing screw 31 can rotate relative to the support block 34 to facilitate the removal of the fixing screw.

[0035] This design ensures that both the inner and outer ends of the screw 31 are stable and fixed, and facilitates disassembly. When needed, the clip 32 can be removed to disassemble the screw 31, support block, and support roller. During disassembly, first remove the clip 32, then expose the free end of the screw 31. Then rotate the screw 31 to separate it from the inner wall 281, thus removing the fixation and allowing for disassembly.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
