[0043] Figure 2 FIG. 1 is a schematic diagram of an exploded structure of an automatic loading structure of a crawler transport vehicle according to an embodiment of the present invention. Figure 2 As shown, the automatic loading structure at least includes a dump bucket assembly 100, a bucket assembly 200 and a bucket driving component. The dump bucket assembly 100 is used to be arranged on the main frame of the crawler transporter, the bucket driving component is arranged on the dump bucket assembly 100, the bucket assembly 200 is hingedly connected to the dump bucket assembly 100, and the bucket assembly 200 includes a front shovel 210. The bucket assembly 200 can rotate around the dump bucket assembly 100 under the driving action of the bucket driving component, so that the front shovel 210 can be located below or above the dump bucket assembly 100.
[0044] The dump bucket assembly 100 can be configured as a self-dumping structure, specifically, it is arranged on the main frame; the bucket driving component as the driving component of the bucket assembly 200 is arranged on the dump bucket assembly 100, and the bucket assembly 200 as the driven component is also arranged on the dump bucket assembly 100. The bucket assembly 100 of the utility model serves as a fixed part in the automatic loading structure, while the bucket driving component and the bucket assembly 200 serve as movable parts. The bucket assembly 200 can rotate counterclockwise from the bottom of the bucket assembly 100 to the top of the bucket assembly 100 under the driving action of the bucket driving component, that is, when the bucket assembly 200 is located below the bucket assembly 100, the material on the ground is automatically loaded into the front shovel 210, and then the bucket driving component drives the bucket assembly 200 to rotate counterclockwise around the bucket assembly 100 until it rotates to the top of the bucket assembly 100, and unloads the material in the front shovel 210 into the bucket, thereby realizing automatic loading of the crawler transport vehicle.
[0045] Since the bucket assembly 200 is hingedly connected to the dump bucket assembly 100 , when the bucket assembly 200 rotates from the bottom of the dump bucket assembly 100 to the top of the dump bucket assembly 100 , the material discharge port of the bucket faces the dump bucket. Figure 3 FIG. 2 is a schematic diagram of the structure of the automatic loading structure of an embodiment of the present invention when the front shovel 210 is located below the dump bucket assembly 100. Figure 3 and Figure 4 It can be seen that the front shovel 210 is located at the lower left of the dump bucket; Figure 5 FIG. 2 is a schematic diagram of the structure of the automatic loading structure of an embodiment of the present utility model when the front shovel 210 is located in front of the dump bucket assembly 100. Figure 5 and Figure 6 As shown, the front shovel 210 is driven by the bucket driving component and is moved to the front of the dump bucket assembly 100; Figure 7 FIG. 2 is a schematic diagram of a structure of an automatic loading structure of an embodiment of the present invention when the front shovel 210 is located above the dump bucket assembly 100. In this figure, the front shovel 210 is further driven by the bucket driving component to rotate from the front of the dump bucket assembly 100 to the top of the dump bucket assembly 100. Figure 8 As shown, at this time, the front shovel 210 is in a vertical state, and the material in the front shovel 210 is unloaded from the discharge port of the front shovel 210 into the dump bucket.
[0046] In some embodiments, the bucket driving component is a cylinder 300, the cylinder end of the cylinder 300 is hingedly connected to the bucket assembly 100, and the cylinder rod end of the cylinder 300 is hingedly connected to the bucket assembly 200. In this embodiment, the cylinder 300 drives the bucket assembly 200 to rotate by the telescopic movement of the cylinder rod. Figure 2 and Fig.14As shown, both the cylinder end and the cylinder rod end of the oil cylinder 300 have a shaft through hole, and the corresponding cylinder end is hingedly connected to the dump bucket assembly 100 through the shaft 500, and the cylinder rod end is also hingedly connected to the bucket assembly 200 through the shaft 500. It can be understood that the bucket driving component is set as the oil cylinder 300 in this embodiment, which is only a preferred example. In some other embodiments, the bucket driving component can also be other components other than the oil cylinder 300 that can drive the bucket assembly 200 to rotate, such as a cylinder.
[0047] Fig. 9 This is a structural schematic diagram of a dump bucket assembly 100 of an automatic loading structure according to an embodiment of the utility model. Fig.10 is a front view of the dump bucket assembly 100, Fig.11 is a side view of the dump bucket assembly 100, as shown Fig. 9 , Fig.10 and Fig.11 As shown, the first end of the bottom of the dumper assembly 100 has a connecting ear plate 110, and the cylinder end of the oil cylinder 300 is connected to the connecting ear plate 110 through a rotating shaft 500. Fig.10 In this embodiment, during the extension process of the cylinder rod of the oil cylinder 300, since the bucket assembly 200 rotates counterclockwise, and since the end of the cylinder rod is connected to the bucket assembly 200, as the bucket assembly 200 rotates counterclockwise, the oil cylinder 300 rotates a certain angle around the rotating shaft 500 between the oil cylinder and the bucket assembly.
[0048] In one embodiment, the bucket assembly 200 further includes a support arm 220, a first end of the support arm 220 being fixedly connected to the front shovel 210, and a second end of the support arm 220 being hingedly connected to both the dump bucket assembly and the cylinder rod end. Fig.12 As shown, the support arm 220 is a bent part as a whole, and includes a connecting portion 221 and a supporting portion 222. The end of the connecting portion 221 abuts against the end of the supporting portion 222. The connecting portion 221 is used to achieve connection with the front shovel 210, and the supporting portion 222 is used to achieve connection with the bucket drive component and the dump bucket assembly 100. The connecting portion 221 is inclined relative to the supporting portion 222, and the angle between the connecting portion 221 and the supporting portion 222 is 120 degrees to 175 degrees. In this embodiment, the connecting portion 221 and the supporting portion 222 can be an integral structure, and the support arm 220 is bent as a whole. The first end of the support arm 220 can also be understood as the end of the support arm 220 close to the front shovel 210.
[0049] Furthermore, the number of the supporting arms 220 is two, such as Fig.12As shown, the two support arms 220 are symmetrically arranged on both sides of the front shovel 210, and the second ends of the two support arms 220 are respectively hingedly connected to the two side walls of the dump bucket assembly 100. Fig.13 The right end of the arm 220 shown, from Fig.13 It can be seen that the first end of the support arm 220 is fixedly connected to the bottom of the front shovel 210, and the second end of the support arm 220 has two connecting holes, one of which is used for hinged connection with the dump bucket assembly 100, and the other is used for hinged connection with the end of the cylinder rod through the rotating shaft 500.
[0050] When there are two supporting arms 220, there are also two corresponding bucket driving components, which are respectively located on both sides of the dump bucket assembly 100. At this time, connecting ear plates are respectively provided on both sides of the first end of the bottom of the dump bucket assembly 100, and the ends of the cylinder bodies of the two bucket driving components are respectively hingedly connected to the connecting ear plates 110 on both sides of the dump bucket assembly 100 through the rotating shaft 500. In order to prevent the rotating shaft from falling off the connecting ear plates, screws or bolts can be further used to lock them.
[0051] In addition, in order to ensure the firmness of the connection between the support arm 220 and the front shovel 210, there are multiple connection points between the front shovel 210 and the support arm 220, and the centers of the multiple connection points are on a straight line. At this time, the left end connection part 221 of the support arm 220 has multiple bolt connection holes, and the multiple bolt connection holes can be arranged at intervals along the length direction of the support arm 220. Correspondingly, the bottom wall of the front shovel 210 also has the same number of connection holes as the connection part 221, and the connection part 221 of the front shovel 210 and the support arm 220 is further connected by screws or bolts.
[0052] Furthermore, the angle between the front shovel 210 and the support arm 220 can be adjusted. For example, the connection hole on the front shovel 210 is a waist-shaped hole, and the support arm 220 and the front shovel 210 can achieve angle adjustment through the waist-shaped hole. When adjusting the angle between the front shovel 210 and the support arm 220, the bolts on the connecting portion 221 can be first loosened, and the support arm 220 or the front shovel 210 can be further moved so that the angle between the front shovel 210 and the support arm 220 reaches the expected angle, and then the bolts on the connecting portion 221 can be tightened. It can be understood that in this embodiment, the waist-shaped hole is set on the front shovel 210 for only an example. In other embodiments, the waist-shaped hole can also be set on the support arm 220.
[0053] In one embodiment, the automatic loading structure further includes a pin 400, a locking nut and a locking ring 410, the second end of the support arm 220 has a sleeve, the side wall of the dump bucket assembly 100 has an axial hole, the pin 400 is located in the sleeve and the axial hole, the locking nut and the locking ring 410 are respectively located at both ends of the pin 400, and the locking ring 410 is located on the outside of the support arm 220, and the outside of the support arm can also be understood as the side of the support arm away from the side wall of the dump bucket assembly 100. The pin 400 realizes the hinged connection between the support arm 220 and the dump bucket assembly 100. When the number of the support arms 220 is two, the two side walls of the dump bucket assembly 100 are provided with axial holes. The shaft hole includes a square hole section and a circular hole section. The square hole section is located at one end of the side wall of the dump bucket assembly 100 close to the support arm 220. The pin shaft 400 has a square shaft section at a position corresponding to the square hole section. When the support arm 220 and the dump bucket assembly 100 are connected, the locking nut is located inside the dump bucket, and the locking ring 410 is located outside the support arm 220. The locking ring 410 is used to limit the support arm 220 from moving outward along the pin shaft 400, that is, the locking ring 410 and the locking nut jointly realize the axial limit of the pin shaft 400. In addition, the square shaft section on the pin shaft 400 cooperates with the square hole section on the side wall of the dump bucket assembly 100 to also play a role in axial positioning, so that this structure further improves the connection stability between the support arm 220 and the dump bucket assembly 100.
[0054] For the automatic loading structure in the above embodiment, when the crawler transport vehicle is ready to load, the cylinder rod of the oil cylinder is in a retracted state, and the front shovel is in the lowest position. In this state, the transport vehicle is driven forward to load; when the front shovel is full of material, the cylinder rod of the oil cylinder slowly extends outward, and under the action of the cylinder rod, the front shovel assembly slowly moves upward in a counterclockwise circular motion around the rotating shaft of the support arm and the dump bucket assembly. When the upward movement reaches a certain state, the material in the front shovel will gradually fall into the dump bucket under the action of gravity. When the cylinder rod of the oil cylinder is fully extended, the front shovel of the front shovel assembly is basically directly above the dump bucket, and the material in the front shovel has completely fallen into the dump bucket; further, the cylinder rod of the oil cylinder is gradually retracted, and the front shovel assembly will rotate around the connecting rotating shaft of the support arm and the dump bucket assembly, and gradually fall back to the ground. Repeat the above actions to fill the dump bucket with materials.
[0055] Through the above embodiments, it can be found that the automatic loading structure of the crawler transport vehicle disclosed by the utility model realizes automatic loading of materials through the front shovel based on the drive of the bucket driving component, and does not need to rely on external machinery or manual loading of materials. Therefore, the automatic loading structure improves the material loading efficiency of the crawler transport vehicle and reduces the material loading cost, thereby reducing the production cost and improving the work efficiency. In addition, the automatic loading structure is simple and easy to install. In addition, the angle between the front shovel and the support arm is adjustable, and the pin shaft used to realize the hinged connection between the support arm and the dump bucket assembly has a square shaft section, which is arranged in the square hole section of the dump bucket assembly. The above structure further ensures the rotation stability between the support arm and the dump bucket assembly, thereby improving the stability of the crawler transport vehicle and extending the working life of the crawler transport vehicle.
[0056] According to another aspect of the utility model, a crawler transport vehicle is also disclosed. The crawler transport vehicle includes the automatic loading structure as described in any of the above embodiments.
[0057] In the present invention, features described and / or illustrated for one embodiment may be used in the same manner or in a similar manner in one or more other embodiments, and / or combined with features of other embodiments or replace features of other embodiments.
