[0058] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0059] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0060] As a first aspect of this utility model, a mounting device is provided for a tractor, such as... Figures 1 to 4 As shown, the mounting device includes a mounting actuator 100 and a base 200, the base 200 being mounted on the tractor. The mounting device further includes a base buffer assembly 300 and a guide limiting assembly. The base 200 is mounted on the tractor via the base buffer assembly 300, allowing the base 200 to move in at least one degree of freedom. The guide limiting assembly is disposed on the base 200 and defines a guide channel 400 with an opening.

[0061] The mounting actuator 100 includes a mounting actuator 110, an actuator drive assembly 120, and a sensing assembly 130. The mounting actuator 110 is mounted on the base 200. The sensing assembly 130 is used to send a first control signal to the mounting actuator 110 when it detects that the mounting mating part 800 has entered the guide channel 400 and reached the set mounting position. The actuator drive assembly 120 is used to drive the mounting actuator 110 into the guide channel 400 when it receives the first control signal.

[0062] After the mounting device is installed on the tractor, the base buffer assembly 300 achieves a flexible connection between the base and the tractor. Therefore, mounting between the tractor and the material car (i.e., as...) is achieved... Figure 5 ,as well as Figure 7 As shown, during the process of the material car mounting fitting 800 and mounting actuator 110 engaging, the base 200 can move within a small range, which makes it easier for the material car mounting fitting 800 and mounting actuator 110 to dock, and avoids damage to the tractor and the material car.

[0063] In addition, the sensing component 130 can trigger the mounting actuator 110 to enter the guide channel and cooperate with the mounting component 800 when the mounting assembly 800 is in place, so as to complete the automatic mounting of the tractor and the material car and improve the mounting efficiency.

[0064] The actuator drive assembly 120 can also drive the mounted actuator 110 away from the guide channel 400 when it receives the second control signal, so as to release the engagement between the mounted actuator 110 and the mounted mating part 800 and complete the automatic unloading of the material car from the tractor.

[0065] It should be pointed out that, in Figure 1 and Figure 4 In the embodiment shown, the mounting actuator has been inserted into the guide channel, in Figure 2 and Figure 3 In the embodiment shown, the mounting actuator is not inserted into the guide channel.

[0066] In this embodiment of the invention, the source of the "second control signal" is not specifically limited. For example, the second control signal can be generated and issued by the main control unit of the tractor. Alternatively, it can be generated and issued by a material transfer platform.

[0067] In this embodiment of the invention, the specific structure of the base buffer assembly 300 is not specifically limited, as long as it enables the base 200 to move in at least one degree of freedom and achieves a soft connection between the base 200 and the tractor. It should be noted that the base buffer assembly 300 should also ensure that the base 200 does not experience excessive displacement or misalignment.

[0068] In this embodiment of the invention, there is no special limitation on "at least one degree of freedom," as long as the base 200 can move under the action of an external force. Typically, an object has six degrees of freedom in space; similarly, the base 200 also has six degrees of freedom. During the docking process, it is common for the mounting fitting 800 and the guide channel 400 to misalign in the left-right direction. Accordingly, the base 200 can move at least in the "left-right direction" (i.e., the x-axis or y-axis).

[0069] As an optional implementation method, such as Figure 3 and Figure 4 As shown, the base buffer assembly 300 includes a connecting shaft 310, a plurality of mounting bases 320, a plurality of first buffers 330, and a plurality of buffer blocks 340. The plurality of mounting bases 320 are used to be mounted on the tractor, and a gap is formed between two adjacent mounting bases 320, wherein a plurality of buffer blocks 340 are disposed in the gap.

[0070] The mounting base 320 has a first shaft hole, and the buffer block 340 has a second shaft hole. The axes of the multiple first shaft holes and the multiple second shaft holes are aligned, and the connecting shaft 310 passes through each of the first shaft holes and each of the second shaft holes.

[0071] One side of the buffer block 340 is connected to the base 200, and the other side of the buffer block 340 is provided with a first buffer member 330, so that the first buffer member 330 is located between the buffer block 340 and the tractor.

[0072] By setting the first buffer 330, the base 200 can approach or move away from the mounting surface of the tractor within a certain range, thereby achieving a soft connection of the base 200 to a certain extent.

[0073] To facilitate the movement of the base 200 within a certain radial range of the connecting shaft, the base buffer assembly 300 may optionally include a plurality of buffer bushings 350 corresponding one-to-one with a plurality of mounting bases 320. The buffer bushings 350 are disposed in the first shaft holes of the corresponding mounting bases 320, and the connecting shaft 310 passes through the buffer bushings 350.

[0074] By setting a buffer bushing 350, the impact force generated during the movement of the tractor or during the loading of the tractor and the material car can be absorbed.

[0075] In this invention, the shape and structure of the guide channel are not specifically limited. To better guide the mounting component 800, the opening area of ​​the guide channel 400 may optionally be larger than the cross-sectional area inside the guide channel 400. That is, the guide channel 400 is roughly "trumpet-shaped".

[0076] In this embodiment of the utility model, the guide limiting component includes an execution component mounting plate 440 and a plurality of guide limiting plates, the plurality of guide limiting plates and the execution component mounting plate 440 forming the guide channel.

[0077] The execution component mounting plate 440 has a first execution component through hole that extends through the execution component mounting plate 440 in the thickness direction, and the mounted execution component 110 can pass through the first execution component through hole and enter the guide channel 400.

[0078] When installing the guide limit assembly, the guide limit plate and the execution mounting plate assembly 440 can be installed separately, thereby reducing the assembly difficulty.

[0079] As described above, the guide channel 400 is roughly "trumpet-shaped". As an optional embodiment, the guide limiting plate includes a limiting plate portion and a guide plate portion, one end of the limiting plate portion is disposed on the base, the guide plate portion is disposed at the other end of the limiting plate portion, and there is an angle between the guide plate portion and the limiting plate portion.

[0080] In this embodiment of the utility model, the number of guide limiting plates is not specifically limited. For ease of installation, optionally, the plurality of guide limiting plates include a first guide limiting plate 410, a second guide limiting plate 420, and a third guide limiting plate 430, with the first guide limiting plate 410 and the second guide limiting plate 420 disposed opposite to each other, and the execution component mounting plate 440 and the third guide limiting plate 430 disposed opposite to each other.

[0081] The mounting device also includes at least one auxiliary limiting component 500 and at least one guide plate buffer component 600.

[0082] At least one of the first guide limiting plate 410 and the second guide limiting plate 420 corresponds to the guide plate buffer assembly 600.

[0083] The guide plate buffer assembly 600 is disposed on the outside of the corresponding guide limit plate, and at least one auxiliary limit assembly 500 corresponds to at least one guide plate buffer assembly 600.

[0084] When the mounting assembly 800 does not engage with the mounting actuator 110, the auxiliary limiting component limits the corresponding guide limiting plate to ensure smooth mounting.

[0085] When the mounting fitting 800 and the mounting actuator 110 are engaged, the auxiliary limiting component 500 releases its limiting effect on the corresponding guide limiting plate, so that the guide limiting plate can move under the action of the corresponding guide plate buffer component 600. This allows the guide limiting plate to move slightly during the turning of the tractor, preventing damage to the mounting fitting 800 and the mounting actuator 110.

[0086] As an optional implementation, the guide plate buffer assembly 600 may include a buffer assembly mounting bracket 610, a pivot shaft 620, and a torsion spring 630. The buffer assembly mounting bracket 610 is disposed on the base 200 and located outside the corresponding guide limiting plate. The torsion spring 630 is sleeved on the pivot shaft 620. One end of the pivot shaft 620 is fixed to the actuator mounting plate 440, and the other end of the pivot shaft 620 is fixed to the corresponding buffer assembly mounting bracket 610. One end of the torsion spring 630 abuts against the corresponding guide limiting plate, and the other end of the torsion spring 630 is fixed to the buffer assembly mounting bracket 610.

[0087] By setting the torsion spring 630, the guide limit plate can be buffered and reset.

[0088] As an optional implementation, guide plate buffer assemblies 600 can be provided on the outer side of the first guide limiting plate 410 and the outer side of the second guide limiting plate 420.

[0089] In this embodiment of the invention, the specific structure of the auxiliary limiting component 500 is not specifically limited. As an optional implementation, a second execution component through hole is formed on the third guide limiting plate 430, extending through the third guide limiting plate along the thickness direction, and the second execution component through hole is opposite to the first execution component through hole.

[0090] The mounting device also includes a pressure-bearing component 700, a portion of which is located outside the third guide limiting plate and opposite to the through hole of the second actuation component.

[0091] like Figure 9 As shown, the auxiliary limiting component 500 includes a limiting post 510 and an elastic element 520. A limiting post hole is formed on the corresponding mounting bracket 610. The limiting post 510 can pass through the limiting post hole, and the axial direction of the limiting post 510 is consistent with the moving direction of the mounting actuator 110. One end of the limiting post 510 is connected to the elastic element 520, and the elastic element 520 is connected to the pressure bearing member 700. When the pressure bearing member 700 is not subjected to external force, the limiting post 510 protrudes out of the corresponding mounting bracket 610.

[0092] In this embodiment of the invention, when the mounting actuator 110 is not in contact with the pressure bearing 700, the limiting post 510 protrudes from the corresponding mounting bracket 610. As the mounting actuator 110 moves further (in... Figure 3 and Figure 4 In the embodiment shown, the mounting actuator 110 (moving downwards) passes through the through hole of the second actuator component, applies pressure to the pressure bearing 700, and drives the limiting post 510 to move against the elastic force of the elastic member 520. This structure ensures that the limiting post 510 protrudes from the mounting frame 610 during mounting, limiting the guide limiting plate; and that after mounting, the limiting post 510 does not protrude from the mounting frame 610, releasing the limiting effect on the guide limiting plate.

[0093] In this embodiment of the utility model, the structure of the pressure-bearing component 700 is not specifically limited. As an optional implementation, the pressure-bearing component 700 is generally U-shaped. That is, the pressure-bearing component 700 may include a pressure-bearing component base plate 730, a first pressure-bearing component connecting plate 710, and a second pressure-bearing component connecting plate 720. The first pressure-bearing component connecting plate 710 and the second pressure-bearing component connecting plate 720 are respectively disposed at both ends of the pressure-bearing component base plate 730 and are respectively connected to the mounting bracket 610 corresponding to the first guide limiting plate 410 and the mounting bracket 610 corresponding to the second guide limiting plate 420. The pressure-bearing component base plate 730 is opposite to the third guide limiting plate 430, and the elastic element 520 is disposed on the pressure-bearing component base plate 730.

[0094] As an optional implementation, both the first guide limiting plate 410 and the second guide limiting plate 420 have corresponding guide plate buffer assemblies 600, so the auxiliary limiting assembly 500 may also include an auxiliary connecting plate 530 connecting the two mounting brackets 610.

[0095] In this embodiment of the invention, the specific structure of the actuator drive assembly 120 is not specifically limited. Optionally, the actuator drive assembly 120 includes a lead screw 121, a lead screw drive motor 122, and a drive assembly mounting bracket 126. The lead screw 121 and the lead screw drive motor 122 are fixed to the base 200 via the drive assembly mounting bracket 126. The lead screw drive motor 122 is used to drive the lead screw 121 to move inward toward the guide channel 400 when receiving the first control signal, ultimately realizing the mounting of the tractor and the material car. Furthermore, the lead screw drive motor 122 is also used to drive the lead screw 121 to move outward toward the guide channel 400 when receiving the second control signal, ultimately realizing the unloading of the material car from the tractor.

[0096] To ensure the stability of the lead screw 121, the actuator drive assembly 120 may optionally include a mechanism connecting plate 123, at least one guide shaft 124, and a linear bearing 125 that mates with the guide shaft 124. The linear bearing 125 is mounted on the drive assembly mounting bracket 126, the mechanism connecting plate 123 is located on the side of the drive assembly mounting bracket 126 facing the guide channel, one end of the guide shaft 124 and the lead screw 121 are connected to the mechanism connecting plate 123, and the other end of the guide shaft 124 is inserted into the corresponding linear bearing 125.

[0097] As an optional implementation, a buffer pad is provided in the guide channel opposite to the outlet of the guide channel.

[0098] In this embodiment of the present invention, the specific structure of the sensing component 130 is not specifically limited. Optionally, the sensing component 130 may include a photoelectric sensor.

[0099] As a second aspect of this utility model, a tractor is provided, the tractor comprising a vehicle body and a mounting device disposed on the vehicle body, wherein the mounting device is the mounting device provided in the first aspect of this utility model.

[0100] As a third aspect of this utility model, a material transport system is provided, the material transport system including a tractor and a material car with a mounting fitting 800, wherein the tractor is the tractor provided in the second aspect of this utility model, and the mounting fitting can enter the guide channel and cooperate with the mounting actuator 110.

[0101] After the mounting device is installed on the tractor, the base buffer assembly 300 achieves a flexible connection between the base and the tractor. Therefore, during the mounting process between the tractor and the material car (i.e., the mounting fitting of the material car and the mounting actuator 110 engage), the base 200 can move within a small range, which facilitates the docking of the mounting fitting of the material car and the mounting actuator 110, and avoids damage to the tractor and the material car.

[0102] In addition, the sensing component 130 can trigger the mounting actuator 110 to enter the guide channel and cooperate with the mounting component when the mounting assembly is in place, so as to complete the automatic mounting of the tractor and the material car and improve the mounting efficiency.

[0103] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
