Description

Technical Field

[0001] The utility model relates to the technical field of coal slime stirring, in particular to a pneumatic large-particle coal slime stirring auxiliary device. Background Art

[0002] Coal slime refers to a semi-solid substance formed by coal powder containing water. It is a product in the coal production process. Depending on the variety and formation mechanism, its properties vary greatly, and its availability also varies greatly. It has many types and a wide range of uses. During production, coal slime is mostly made from coal blocks processed through a stirring and crushing device.

[0003] However, when the existing stirring and breaking devices process coal blocks into large-particle coal slime, most of them directly put the coal blocks into the stirring box of the stirring and breaking device and break them up through the breaking device, resulting in a long breaking time of the coal blocks in the stirring and breaking device, resulting in low breaking efficiency of the coal blocks by the stirring and breaking device, which cannot meet the existing coal slime production needs. Secondly, the loading of coal blocks is mostly done manually, which increases the workload of the staff. Utility Model Content

[0004] In order to solve the problem that when existing stirring and breaking devices process coal blocks into large-particle coal slime, the coal blocks are mostly directly placed into the stirring box of the stirring and breaking device and broken by the breaking device, resulting in low efficiency of the stirring and breaking device in breaking the coal blocks; the purpose of this utility model is to provide a pneumatic large-particle coal slime stirring auxiliary device.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a pneumatic large-particle coal slime stirring auxiliary device, comprising a fixed platform, a stirring and breaking device and a crushing device are fixedly installed on the top surface of the fixed platform, the stirring and breaking device comprises a stirring box, the crushing device comprises a fixed frame, a cylinder is fixedly installed in the middle of the top surface of the fixed frame, a pressure plate is fixedly installed on the output end of the cylinder, and evenly distributed crushing heads are fixedly installed on the bottom surface of the pressure plate, and positioning frames are fixedly installed on both sides of the fixed frame, and the number of the positioning frames is two;

[0006] A crushing box is fixedly installed between the two positioning frames, a fixed frame is fixedly installed in the crushing box, a fixed rod is fixedly installed in the middle of the fixed frame, and evenly distributed crushing knives are fixedly installed on both sides of the fixed rod in the fixed frame. The crushing knives cooperate with the crushing head. The crushing box is located directly above the mixing box, and the crushing device cooperates with the mixing and crushing device.

[0007] Preferably, an intermittent conveying mechanism is installed on one side of the fixed platform, and the intermittent conveying mechanism includes a conveyor belt, and evenly distributed isolation strips are fixedly installed on the surface of the conveyor belt. A discharge platform is fixedly installed at one end of the intermittent conveying mechanism, and the discharge platform cooperates with the crushing box.

[0008] Preferably, the top surface of the fixing frame is located on both sides of the cylinder and fixed sleeves are symmetrically clamped therein, and telescopic rods are symmetrically installed on both sides of the top surface of the pressure plate. The number of the fixed sleeves and telescopic rods is four, and the telescopic rods are slidably installed in the fixed sleeves. A fixing groove is provided in the crushing box, and the fixing frame is fixedly installed in the fixing groove. A protective cover is fixedly installed on the bottom surface of the crushing box, and the protective cover is located directly above the mixing box and cooperates with the mixing box.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. In the utility model, before the coal lumps are crushed by the stirring and crushing device, they are transported to the crushing box of the crushing device by the intermittent conveying mechanism for pre-crushing. After the crushing is completed, they fall into the stirring and crushing device for crushing, thereby improving the crushing efficiency of the coal lumps after entering the stirring and crushing device. This solves the problem that when the coal lumps are directly placed in the stirring and crushing device for crushing, the crushing time of the coal lumps is long, which reduces the crushing efficiency of the stirring and crushing device for the coal lumps.

[0011] 2. In the present invention, with the cooperation of the intermittent conveying mechanism and the unloading platform, the coal blocks that need to be crushed are sequentially conveyed to the crushing box of the crushing device for pre-crushing. After the crushing is completed, they fall into the mixing box of the stirring and crushing device for crushing. There is no need to manually complete the loading of the coal blocks, which reduces the workload of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

The two support frames 43 cooperate with the intermittent conveying mechanism 4 to complete the support and fixation of the intermittent conveying mechanism 4 on one side of the fixed platform 1 through the two support frames 43.

[0025] Working principle: When the coal blocks need to be broken by the stirring and breaking device 2, the coal blocks to be broken are sequentially placed between two adjacent isolation strips 42 on the surface of the conveyor belt 41 in the intermittent conveying mechanism 4, and the coal blocks are conveyed. The conveyed coal blocks fall into the unloading platform 5 in turn, and slide through the unloading platform 5 into the crushing box 35 of the crushing device 3 for pre-crushing.

[0026] Before the coal blocks are crushed by the stirring and crushing device 2, they are transported to the crushing box 35 of the crushing device 3 through the intermittent conveying mechanism 4 for pre-crushing. After the coal blocks are transported to the crushing box 35, the complete coal blocks fall onto the crushing knife 37 installed in the fixed frame 36. The switch of the cylinder 32 is turned on. When the cylinder 32 works, the pressure plate 33 and the crushing head 331 installed on the bottom of the pressure plate 33 are controlled to enter the crushing box 35. With the cooperation of the crushing head 331, the coal blocks on the crushing knife 37 are pressed and crushed. After the coal blocks are crushed in the crushing device 3, they fall into the stirring box 21 of the stirring and crushing device 2 for crushing.
