[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0041] As Figures 1 - 3 shown, the present utility model provides a two - way pushing type self - moving tail equipment for a transfer machine, including:

[0042] The belt rack assembly, there are three belt rack assemblies arranged horizontally.

[0043] Transfer machine assembly, the transfer machine assembly is arranged above the belt rack assembly, and the transfer machine assembly and the second belt rack assembly are connected by a second two-way pushing assembly.

[0044] Wherein, the first two-way pushing assembly assists the movement of the belt rack assembly, and the second two-way pushing assembly assists the movement of the transfer machine assembly.

[0045] Specifically, the belt rack assembly includes:

[0046] Belt horizontal frame 3, the belt horizontal frame 3 is placed horizontally, and a plurality of vertically arranged belt support frames 8 are evenly distributed at the bottom of the belt horizontal frame 3, and a belt support seat 7 is installed at the bottom end of the belt support frame 8;

[0047] A deflecting roller support seat 10 is installed at the tail end of the belt horizontal frame 3 in the third belt rack assembly, and a deflecting roller 9 is rotatably connected to the deflecting roller support seat 10. The belt 11 bypasses the deflecting roller 9 and then completes the deflecting operation of the extension direction;

[0048] A plurality of threaded holes are provided at both ends of the belt horizontal frame 3;

[0049] Two belt horizontal frames 3 are symmetrically arranged and are respectively arranged at both ends of the belt 11, and the extending direction of the belt horizontal frame 3 is parallel to the transportation direction of the belt 11.

[0051] Width adjustment oil cylinder 20, both ends of the width adjustment oil cylinder 20 are respectively connected to two relatively arranged belt support frames 8 through an oil cylinder bolt 18 and an oil cylinder nut 19.

[0052] During specific implementation, the width of the belt rack assembly is controlled by controlling the width adjustment oil cylinder 20 of the device.

[0053] Specifically, the first two-way pushing assembly includes:

[0054] First two-way pushing oil cylinder, both ends of the first two-way pushing oil cylinder are respectively installed on the belt support frame 8 at the tail end in the first belt rack assembly and the belt support frame 8 at the front end of the second belt rack assembly through an oil cylinder support seat 15; two first two-way pushing oil cylinders are correspondingly arranged;

[0055] A limiting conduit 22, wherein two corresponding horizontal limiting conduits 22 are arranged, one of which is installed at the tail end of the belt horizontal frame 3 of the first belt frame assembly, and the other is installed at the front end of the belt horizontal frame 3 of the second belt frame assembly;

[0056] The limiting rod 21 has one end fixedly inserted in one of the limiting conduits 22 and the other end slidably connected in the other limiting conduit 22 .

[0057] When the first bidirectional push cylinder is working, the first belt frame assembly moves forward synchronously or the second and third belt frame assemblies move backward synchronously. During this process, the limiting rod 21 cooperates with the limiting guide tube 22 to limit the forward movement direction of the first belt frame assembly or the backward movement direction of the second and third belt frame assemblies, ensuring that the first belt frame assembly does not move forward obliquely during the forward movement or the second and third belt frame assemblies do not move backward obliquely during the backward movement.

[0058] Specifically, the fixing assembly includes:

[0059] The track clamp 4 is provided with two track clamps 4 and is clamped on both sides of the rear end of the belt horizontal frame 3 in the second belt frame assembly and on both sides of the front end of the belt horizontal frame 3 in the third belt frame assembly. The track clamp 4 and the belt horizontal frame 3 are connected by high-strength bolts 5 and high-strength nuts 6.

[0060] Among them, a plurality of threaded holes are opened on the track clamp plate 4, and the threaded holes opened on the track clamp plate 4 match the threaded holes opened on the belt horizontal frame 3. After passing through the above-mentioned threaded holes, the high-strength bolts 5 are connected with the high-strength nuts 6 to complete the fixation of the plurality of the belt horizontal frames 3.

The fixed ear seat 28 is installed on an oil cylinder fixed frame seat 29, and the oil cylinder fixed frame seat 29 is installed on the belt horizontal frame 3.

[0067] In specific implementation, the oil cylinder fixed frame seat 29 is installed on the belt horizontal frame 3 in the second belt rack assembly. When the belt rack assembly moves forward, the weight of the loading machine assembly is mainly borne by the second belt rack assembly through the second two-way pushing oil cylinder. At this time, when the first two-way pushing oil cylinder works, since the friction between the first belt rack assembly and the ground is less than the friction between the second belt rack assembly and the ground, the first belt rack assembly moves forward under the push of the first two-way pushing oil cylinder.

[0068] Similarly, when the belt rack assembly moves backward, the weight of the loading machine assembly is mainly borne by the first belt rack assembly. The friction between the first belt rack assembly and the ground is greater than the friction between the second belt rack assembly and the ground. Under the push of the first two-way pushing oil cylinder, the second belt rack assembly moves backward.

[0069] It should be noted that before the belt rack assembly moves forward and backward, the belt conveyor needs to be slackened.

[0070] When the second two-way pushing oil cylinder works, it drives the loading machine assembly to move on the belt rack assembly. At the same time, the loading machine assembly is also connected to an external rack device. After the external rack device is fixed, when the second two-way pushing oil cylinder works, the loading machine assembly no longer moves relative to the ground, and the second belt rack assembly moves forward or backward under the drive of the second two-way pushing oil cylinder.

[0071] Specifically, a triple idler 12 is rotatably connected to the top of the belt support frame 8, and the belt 11 is supported above the triple idler 12.

[0072] Specifically, a roller support bracket 14 is installed at the bottom of the belt support frame 8, and a load-carrying idler 13 is rotatably connected to the roller support bracket 14. The belt 11 is supported on the load-carrying idler 13.

[0073] Specifically, the belt support frame 8 has multiple specifications. In specific implementation, those skilled in the art can select the belt support frame 8 with a height dimension that meets the regulations according to the roadway height.

[0074] Specifically, the front and rear ends of the belt support seat 7 are upturned to reduce the resistance suffered by the belt rack assembly during forward or backward movement.

[0075] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0076] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
