Description

Technical Field

[0001] The invention relates to a device capable of loosening block and granular materials, in particular to a material loosening machine. Background Art

[0002] The slag produced during the steelmaking process is generally transported by rail cars to a slag receiving tank set below the ground after preliminary treatment, and then transported to subsequent slag reprocessing equipment via a belt conveyor in the slag receiving tank. After the rail car arrives at the area where the slag receiving tank is located, the bottom of the compartment plates on both sides of the rail car will open, and the slag will automatically flow out of the rail car compartment and into the slag receiving tank under the action of gravity; however, the slag is prone to compaction in the rail car, especially in winter, because the water on the surface of the slag will cause ice, and the compaction situation is more serious. The slag often flows out of the rail car slowly or even fails to flow out. Therefore, it is very necessary to design a device that can loosen the slag, and the present invention is made based on this.

[0003] In addition, the transported coal powder, fly ash or coal blocks are easy to freeze in winter, and the landslide in the existing technology cannot achieve fully automatic sliding, and manual assistance is required for unloading, which increases the difficulty of unloading and reduces labor efficiency. Summary of the invention

The transverse connecting frame and the longitudinal connecting frame form a U-shaped bracket, and two sets of material loosening mechanisms are respectively arranged along the two longitudinal connecting frames.

[0008] The slewing mechanism comprises a hinge shaft connected to the upper arm through a bearing, one end of the hinge shaft is connected to the loosening mechanism frame, and the other end of the hinge shaft is connected to the driving device. The driving device drives the hinge shaft to rotate to realize the swing of the loosening mechanism frame.

[0009] The slewing mechanism comprises a slewing bearing, and the loosening mechanism frame is connected to the boom via the slewing bearing. The swing of the loosening mechanism frame is driven by a driving device which is dynamically connected to the slewing bearing.

[0023] Reference Figure 1 The material loosening machine provided by the present invention includes a movable frame 1, the frame 1 is a door-type frame, the frame 1 is connected to two guide rails 18 by rotating the roller 17 connected to the bottom thereof, the frame 1 is connected with a power device for driving the roller to rotate (the power device is generally a motor, not shown in the figure), the power device is connected to the roller shaft through a gear transmission chain or a chain sprocket transmission chain to drive the roller to roll along the guide rail to drive the frame 1 to move, which is a prior art. The above-mentioned roller rotation driven by the power device is only one of the prior art. Of course, other driving methods can also be used to move the frame along the guide rail, which will not be repeated here. A material loosening assembly is provided on the top of the frame 1; the material loosening assembly includes a large arm 2 with one end hinged to the top of the frame 1, and the up and down swing of the large arm 2 is driven by a cylinder 3 with one end connected to the frame 1 and the other end hinged to the large arm 2; the other end of the large arm 2 is connected to the loosening mechanism frame 4 through a slewing mechanism.

[0024] Reference Figure 2 The loosening mechanism frame 4 includes a connecting frame 12 for connecting with the upper arm 2, a transverse connecting frame 13 is connected to the connecting frame 12, and both ends of the transverse connecting frame 13 are respectively connected to longitudinal connecting frames 14, and the transverse connecting frame 13 and the longitudinal connecting frame 14 form a U-shaped bracket.

[0025] The slewing mechanism can be in the following three ways: one is that the boom 2 is connected with a rotatable hinge shaft through a bearing, one end of the hinge shaft is connected to the connecting frame 12 of the loosening mechanism frame 4, and the other end of the hinge shaft is connected to the driving device power, and the driving device (motor or hydraulic motor) drives the hinge shaft to rotate through a gear transmission chain or a chain sprocket transmission chain to realize the swing of the loosening mechanism frame 4. The other is to use a slewing bearing to realize the connection between the boom 2 and the loosening mechanism frame 4; the slewing bearing is a commonly used mechanical component, which is composed of inner and outer rings, rolling elements, etc., and the inner ring has teeth or the outer ring has teeth. The present invention can use a slewing bearing with teeth on the outer ring, connect its inner ring with the boom 2, and connect its outer ring with the connecting frame 12 of the loosening mechanism frame 4, and the driving device (motor or hydraulic motor) is installed on the boom 2, and the driving device is equipped with a gear meshing with the teeth on the outer ring, and the swing of the loosening mechanism frame 4 is driven by the driving device. The third way is to adopt a rotary drive, which is also a commonly used mechanical component. The rotary drive is a full-circle rotary reduction transmission mechanism that integrates a driving power source. It uses a rotary bearing as a transmission follower and a mechanism attachment. By attaching an active part, a driving source and a cover shell to one of the inner and outer circles of the rotary bearing, and using the other circle as both a transmission follower and a connecting base for the driven working parts, the characteristic of the rotary bearing itself as a full-circle rotary connecting part is utilized to efficiently configure the driving power source and the main transmission parts, making it a universal reduction transmission mechanism that integrates rotation, reduction and driving functions while having a simple structure, and is easy to manufacture and maintain. According to the speed transmission form of the rotary drive, it can be divided into a gear type rotary drive and a worm gear type rotary drive. The present invention adopts a worm gear type rotary drive, and realizes the connection between the connecting frame 12 of the loosening mechanism frame 4 and the upper arm 2 through the rotary bearing of the rotary drive, and the swing of the loosening mechanism frame 4 can be realized by driving the power source (motor or hydraulic motor) of the rotary drive. The present invention takes the third rotary mechanism as the best embodiment. Figure 1 The structure shown is a schematic diagram of a rotary drive 22.

[0026] Reference Figure 2 , a loosening mechanism is provided on the loosening mechanism frame 4; the loosening mechanism includes a sprocket drive motor 6 installed on the loosening mechanism frame 4 and a sprocket shaft 5 rotatably connected to the loosening mechanism frame 4, the sprocket drive motor 6 is arranged close to the upper arm 2, that is, close to the connecting end of the loosening mechanism frame 4 and the upper arm 2, and the sprocket shaft 5 is arranged away from the upper arm 2, that is, away from the connecting end of the loosening mechanism frame 4 and the upper arm 2, a driven sprocket 7 is fixedly installed on the sprocket shaft 5, a driving sprocket 8 is installed on the sprocket drive motor 6, a chain 9 is installed on the driven sprocket 7 and the driving sprocket 8, a plurality of loosening sheets 10 arranged at intervals are installed on the chain 9, and a loosening wheel 15 is fixedly installed at each end of the sprocket shaft 5; refer to Figure 4The loosening wheel 15 includes a wheel body 16 connected to the sprocket shaft 5, and a plurality of loosening teeth 11 are arranged at intervals on the wheel body 16. The loosening mechanism is composed of two sets, and the two sets of loosening mechanisms are respectively arranged on the two sides of the loosening mechanism frame 4, that is, respectively arranged along the two longitudinal connecting frames 14 of the loosening mechanism frame 4. The driven sprocket 7 of one set of loosening mechanisms is arranged at the outer end of one longitudinal connecting frame 14, and the sprocket drive motor 6 of the loosening mechanism is arranged near the inner end of the longitudinal connecting frame 14 (the end where the longitudinal connecting frame 14 and the transverse connecting frame 13 are connected); the driven sprocket 7 of the other set of loosening mechanisms is arranged at the outer end of the other longitudinal connecting frame 14, and the sprocket drive motor 6 of the loosening mechanism is arranged near the inner end of the longitudinal connecting frame 14.

[0027] Continue to refer to Figure 2 , the loosening piece 10 is tilted, that is, the loosening piece 10 forms a set angle with the length direction of the chain plate of the chain; among the multiple loosening pieces 10: the tilting directions of two adjacent loosening pieces 10 are opposite. The loosening piece 10 can loosen the material (such as slag) during the rotation of the chain, and the setting of the loosening piece 10 can prevent the chain from directly contacting the compacted material clumps, and can protect the chain; that is to say, the loosening piece 10 can dig a groove in the material (such as slag) for the chain to rotate. In order to prevent the loosened material in the groove from affecting the chain, the loosening piece 10 is tilted and the tilting directions of two adjacent loosening pieces 10 are set to be opposite, so that the loosened material can be taken out of the groove and thrown to both sides of the chain, which can more effectively protect the chain; Figure 2 Only a section of the loose pieces on the chain is shown to illustrate the arrangement of the loose pieces 10 on the chain. The number of loose pieces 10 shown does not represent the actual number. The actual number can be arranged on the chain with multiple loose pieces 10 spaced apart according to design requirements. Figure 5 The bottom of the loose piece 10 is fixedly connected with a connecting seat 19, and the loose piece 10 is fixedly connected to the connecting seat at an angle; Figure 3 A loose material piece connecting frame 20 is fixedly connected to the chain plate 21 of the chain 9, and the loose material piece 10 is fixedly connected to the loose material piece connecting frame through a connecting seat; since the loose material piece 10 is fixedly connected to the connecting seat at an angle, after the connecting seat is connected to the loose material piece connecting frame, the loose material piece 10 also forms a set angle with the length direction of the chain plate of the chain 9, that is, the loose material piece 10 is set at an angle.

[0028] Reference Figure 1 The material loosening assembly is divided into two groups, and the two groups of material loosening assemblies are respectively arranged on the opposite sides of the top of the frame 1. According to the working conditions, one group of material loosening assemblies can be used to loosen the material, or two groups of material loosening assemblies can be used at the same time to loosen the material.

[0029] The material loosening machine is used as follows: after the rail car transporting the slag arrives at the designated location, the lower half of the compartment plates on both sides of the rail car opens to allow the slag in the car to flow out; when the slag in the rail car flows out slowly or does not flow out, the material loosening machine can be moved to the rail car so that the material loosening assembly is located directly above the rail car, the oil cylinder is started to flip the big arm down and the loosening mechanism frame is swung toward the slag through the slewing mechanism, and the sprocket drive motor is started at the same time. The sprocket drive motor drives the loosening wheel to rotate through the chain, and the rotating loosening wheel can loosen the slag through the loosening teeth, and the loosening sheet on the chain can also loosen the slag. After the slag is loosened, it can flow out of the rail car smoothly. By adjusting the downward flip angle of the big arm and the swing angle of the loosening mechanism frame, the loosening wheel can enter the bottom layer of the slag from the surface layer of the slag to loosen the slag. The above usage is only described by taking steelmaking slag as an example. The present invention can also be used for loosening power plant slag and other materials. In addition, the present invention can also be applied to the automatic loosening and unloading of agglomerated coal powder, fly ash or coal blocks.
