Description

Technical Field

[0001] The utility model relates to the field of spiral coal unloading machines, in particular to a quick-loading mechanism and a spiral coal unloading device. Background Art

[0002] The spiral coal unloader is an important equipment for unloading coal from railway cars. Its structure is composed of spiral blades, spiral support frames, reducers and motors. When the spiral blades rotate and contact the coal, the coal in contact with the spiral blades is pushed out of the railway car and falls into the coal pit and enters the belt. The unloading operation is convenient, it has strong adaptability to different types of railway cars, and the equipment is simple. It is a commonly used coal unloading device. However, due to the special structural characteristics, the spiral blades will deform and curl during long-term use, which affects the normal unloading efficiency of the coal, increases the number of replacement times of the spiral blades, and increases the use cost of coal unloading. Therefore, a quick-loading mechanism is proposed.

[0003] Moreover, the coal unloading height of the spiral coal unloading device in the prior art is limited. After the spiral coal unloader has unloaded the coal from the car body, a thick layer of coal will be left in the middle of the car body, and the car cleaning personnel are required to clean up the remaining coal. When controlling the descending height of the spiral coal unloader to reduce the accumulation of coal at the bottom of the car body, the distance between the spiral blades of the spiral coal unloader and the car body cannot be accurately controlled. There is a phenomenon that the coal is thickly accumulated and the blades collide with the car body during the unloading process. Therefore, a spiral coal unloading device is proposed.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Secondly, the "one embodiment" or "embodiment" referred to herein refers to a specific feature, structure or characteristic that can be included in at least one implementation of the utility model. The "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1 , Figure 2 and Figure 4 , which is the first embodiment of the utility model, and this embodiment provides a quick-install mechanism.

[0035] The quick-install mechanism includes a connecting assembly 100 .

[0036] Specifically, the connecting component 100 includes a protective tooth block 101, which is arranged in a ring array. The setting of the protective tooth block 101 can effectively prevent the bending and curling of the spiral sheet. A connecting rod 102 is arranged inside the protective tooth block 101, and a locking piece 103 is arranged at the bottom of the connecting rod 102. Through the matching setting between the locking piece 103 and the connecting rod 102, the protective tooth block 101 is effectively installed on the spiral sheet. Adjusting pieces 104 are symmetrically arranged on the middle part of the connecting rod 102, and an anti-slip piece 105 is arranged on one side of the adjusting piece 104. Through the setting of the adjusting piece 104 and the anti-slip piece 105, the adjusted connecting rod 102 can be effectively limited and fixed to prevent the protective tooth block 101 from being pulled out of the protective tooth block 101 when the spiral sheet rotates, thereby ensuring the firmness of the protective tooth block 101.

[0037] Preferably, a first spring 103a is symmetrically arranged on the bottom of the connecting rod 102, and a first limiting ball 103b is arranged on one side of the first spring 103a. Through the setting of the first spring 103a, when the connecting rod 102 moves downward, when it is restricted by the diameter of the limiting hole, the first spring 103a is squeezed, so that the first limiting ball 103b is movably installed on both sides of the connecting rod 102. When the bottom placement hole area of ​​the limiting hole increases, the first spring 103a is no longer affected by the external force and the elastic force is restored, so that the first limiting ball on one side of the first spring 103a pops out and engages in the inside of the protective tooth block 101, thereby achieving the limiting and fixing effect of the connecting rod 102.

[0038] Example 2

[0039] Reference Figure 1-4 , which is the second embodiment of the utility model, is based on the previous embodiment, and is different from the previous embodiment in that: this embodiment provides a quick-install mechanism.

[0040] The connection assembly 100 includes an adjustment member 104 .

[0041] Specifically, a second limiting ball 104a is symmetrically arranged on the middle part of the connecting rod 102. Through the arrangement of the second limiting ball 104a, the connecting rod 102 is effectively limited and fixed to prevent the connecting rod 102 from slipping. An adjustment plate 104b is welded to the outer side of the second limiting ball 104a. Through the arrangement of the adjustment plate 104b, the second limiting ball 104a is effectively connected to the second spring 104d. A locking hole 104c is opened on one side of the adjusting plate 104b. Through the arrangement of the locking hole 104c, the anti-slip rod 105 is convenient to a, the other end of the adjusting plate 104b is provided with a second spring 104d. The second spring 104d can be easily restored to restore the elastic force after installation without the influence of external force, so that the second limiting ball 104a is engaged and installed on both sides of the middle part of the connecting rod 102, so as to avoid the connecting rod 102 from falling during use, thereby ensuring the installation effect of the protective tooth block 101. The second limiting ball 104a, the adjusting plate 104b and the second spring 104d are all movably installed inside the protective tooth block 101.

[0042] Preferably, an anti-slip rod 105a is movably inserted inside the lock hole 104c. The anti-slip rod 105a can be set to prevent the second spring 104d from being squeezed by external force during use, causing the adjustment plate 104b and the second limiting ball 104a to be displaced, thereby releasing the limiting and fixing of the connecting rod 102, so that the connecting rod 102 falls from the protective tooth block 101 under the influence of the rotation of the protective tooth block 101 and the external force of the coal, and then the protective tooth block 101 falls from the spiral sheet;

[0043] It is worth noting that: the diameter of the placement hole inside the limiting hole is larger than the surface diameter, a limiting block 105b is welded to the outer side of the bottom of the anti-slip rod 105a, and the limiting block 105b is semicircular, and a rubber block 105c is arranged at the bottom of the anti-slip rod 105a. Through the cooperation between the limiting block 105b and the rubber block 105c, when the anti-slip rod 105a is inserted into the deep inside of the limiting hole with the limiting block 105b and the rubber block 105c, and then rotated, the anti-slip rod 105a is released after rotation, and the rubber block 105c recovers its strength without being squeezed by external force, and bounces the limiting block 105b outward to the top of the inner circle of the limiting hole, so that the limiting block 105b is limited and fixed, thereby realizing the initial limiting of the anti-slip rod 105a, and at the same time realizing the limiting of the adjustment plate 104b.

[0044] Furthermore, a clamping block 105d is slidably installed on the anti-slip rod 105a, and a limiting groove is symmetrically provided on the protective tooth block 101. Through the cooperation between the clamping block 105d and the limiting groove, the clamping block 105d is movably engaged with the protective tooth block 101 through the limiting groove, thereby realizing secondary limiting of the anti-slip rod 105a, effectively preventing the anti-slip rod 105a from falling off during use, and at the same time facilitating quick disassembly and assembly during replacement.

[0045] When in use, first, after the connecting rod 102 is successfully installed on the protective tooth block 101, under the elastic force of the second spring 104d, the adjustment plate 104b and the second limiting ball 104a are pushed to move to the center position, and are movably engaged on both sides of the connecting rod 102e to achieve secondary limiting fixation of the connecting rod 102, and then the anti-slip rod 105a is inserted into the adjustment plate 104b through the lock hole 104c, and then the anti-slip block 105a is rotated so that the limiting ball on the anti-slip block 105a is fixed. Block 105b is rotated to the inner circle of the limiting hole, and the anti-slip rod 105a is released. Under the push of the elastic force of the rubber block 105c, the limiting block 105b and the anti-slip rod 105a slide outward until the limiting block 105b is restricted to the top of the inner circle of the limiting hole, thereby achieving the limiting fixation of the adjustment plate 104b, and then pushing the clamping block 105d so that the clamping block 105d is inserted into the limiting groove to achieve the limiting fixation of the anti-slip rod 105a, thereby achieving the rapid installation of the overall connecting assembly 100.

[0046] When the protective tooth block 101 needs to be removed from the spiral sheet, the above steps can be performed in reverse, which will not be described in detail here.

[0047] Example 3

[0048] Reference Figure 5-7 , which is the second embodiment of the utility model, is based on the previous embodiment, and is different from the previous embodiment in that: this embodiment provides a coal unloading spiral device.

[0049] The coal unloading screw device includes a mounting assembly 200 .

[0050] Specifically, the mounting assembly 200 includes a mounting seat 201. The mounting seat 201 is provided to effectively facilitate the installation of the bracket 202. The bracket 202 is provided on the top of the mounting seat 201. The bracket 202 is provided to facilitate the installation of the spiral pieces 206 at both ends. The spiral pieces 206 are symmetrically provided on both sides of the bracket 202. The spiral pieces 206 can effectively unload the coal inside the carriage. The spiral pieces 206 are provided inside the protective tooth block 101. The bracket 202 is symmetrically provided with triangular blocks 203. The bracket 202 is provided with triangular blocks 203. The bottom end of the triangular block 203 is lower than the spiral piece 206, so when the spiral piece 206 unloads the coal inside the car, the collision between the spiral piece 206 and the bottom of the car is avoided, thereby reducing the damage of the spiral piece 206. The surface of the triangular block 203 is provided with a protective block 204. Through the setting of the protective block 204, the triangular block 203 is avoided from being worn and consumed during use, and the service life of the triangular block 203 and the bracket 202 is extended. The protective block 204 is symmetrically provided with fixing parts 205. Through the setting of the fixing parts 205, the protective block 204 can be effectively connected and installed with the triangular block 203.

[0051] It is worth noting that the triangular block 203 and the protective block 204 are both set in a triangular shape, which can effectively push the coal in the middle of the carriage to both sides while protecting the spiral blade 206, so that the spiral blade 206 can better transport the coal, avoiding a thicker strip of unprocessed coal in the middle of the carriage after unloading the coal, thereby improving the unloading efficiency and cleanliness of the coal in the carriage.

[0052] Preferably, a fixing rod 205a is provided on the protective block 204. Through the setting of the fixing rod 205a, one end of the protective block 204 and the triangular block 203 can be effectively penetrated, and the bottom of the fixing rod 205a is inserted into the other end of the protective block 204 to achieve the connection between the protective block 204 and the triangular block 203. A placement groove 205b is provided inside the protective block 204. The top opening diameter of the placement groove 205b is larger than the bottom opening diameter. The opening of the placement groove 205b facilitates the installation of the third spring 205c and the fixing block 205d. The third spring 205c is symmetrically provided on the fixing rod 205a, and the fixing block 205d is welded to one end of the third spring 205c. Through the setting of the third spring 205c, the fixing block 205d can extend outward into the protective block 204 without being squeezed by the spatial range, thereby achieving the limited fixation of the fixing rod 205a.
