[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention.

Therefore, they should not be construed as limitations on the embodiments of the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] The following is combined with Figures 1 to 2 The variable bucket of the present invention is described.

[0045] like Figure 1 As shown, an embodiment of the present invention provides a variable bucket, including a bucket body 1, a side plate 2 and a rotating mechanism 3. At least one end of the bucket body 1 is open. The bucket body 1 can generally be understood as a mechanism with a top opening, which is the inlet and outlet of the material. The opening at least one end of the bucket body 1 is understood to mean that it is not completely closed, and there is an opening at least on one side. It can be an opening at one end or an opening at both ends.

[0046] Side plate 2 is a movable component with a first working state and a second working state. The first working state corresponds to side plate 2 closing the opening of the bucket body 1, making the bucket body 1 a completely enclosed space. The second working state corresponds to side plate 2 opening the opening, rotating to the bottom side of the bucket body 1, achieving lateral unobstructed access at the opening. A rotating mechanism 3 is mounted on the bucket body 1, and its output end is connected to side plate 2. Under the action of the rotating mechanism 3, side plate 2 switches between the first and second working states. When the rotating mechanism 3 is activated or driven, it moves side plate 2. When it is necessary to close the bucket body 1, the rotating mechanism 3 drives side plate 2 into the first working state; when it is necessary to open the bucket body 1, the rotating mechanism 3 drives side plate 2 into the second working state.

[0047] This is a variable bucket with variable capacity. The side plate 2 can be opened and closed by the action of the rotating mechanism 3, so as to facilitate the control of the opening state of the bucket body 1. Under the action of the rotating mechanism 3, the side plate 2 switches between the first working state and the second working state. The forward and reverse rotation of the rotating mechanism 3 controls the trajectory of the rotation angle of the side plate 2 during the deformation process, so as to ensure that the side plate 2 operates on a predetermined trajectory. Even if there are residual materials inside the variable bucket, it will not affect the effective closing of the side plate 2 and the opening. At the same time, the side plate 2 switches between the first working state and the second working state through rotation, which can also avoid the collision and wear between the side plate 2 and the bucket body 1. In addition, the variable bucket provided in the embodiment can not only expand the capacity of the bucket, but also has strong loading capacity for loading long strip-shaped objects.

[0048] In a feasible embodiment of the present application, on the basis of the above embodiment, a linear driving mechanism 4 is further included, the linear driving mechanism 4 is rotationally connected with the side plate 2, and there is a connection point between the linear driving mechanism 4 and the side plate 2, allowing the side plate 2 to move under the action of the linear driving mechanism 4. This action can be performed after the side plate 2 has been opened, i.e. when the side plate 2 is in the second working state. Moving the side plate 2 to the bottom of the bucket body 1 can be for more conveniently emptying the materials in the bucket, or for performing certain specific operations or maintenance, or for increasing the capacity of the bucket body 1. In the second working state, the linear driving mechanism 4 is used to move the side plate 2 to the bottom of the bucket body 1. The bottom of the bucket body 1 can be understood as the outside of the bucket, i.e. the side opposite to the inside of the bucket body 1 accommodating the goods. The linear driving mechanism 4 is usually used to shrink the side plate 2 inward after completing the rotation of the side plate 2, so as to avoid unnecessary collision.

[0049] In the above embodiment, the bucket device not only has the function of opening and closing the side plate 2 through the rotating mechanism 3, but also has the function of moving the side plate 2 to the bottom of the bucket body 1 through the linear driving mechanism 4. This multifunctionality makes the bucket device more adaptable to different working environments and requirements.

[0050] It should be noted that when there is only one end opening, the length of the long strip-shaped goods extending to the outside of the bucket body 1 should not be too long, so as to avoid falling due to unstable center of gravity. When there are two end openings, the center of gravity of the goods can be made to coincide with the center of gravity of the bucket, i.e. the lengths of the two ends of the long strip-shaped goods extending to the outside of the bucket body 1 are substantially equal, so as to ensure stability during transportation and prevent falling.

[0051] In one possible embodiment of the present application, the side plate 2 comprises a closure plate 21 and an ear plate 22. The closure plate 21 is used to close the opening, and the shape of the closure plate 21 is matched with the shape of the opening to ensure that the closure plate 21 can tightly close the opening to prevent material from leaking out of the opening. The ear plate 22 is integrally connected with the closure plate 21, and the ear plate 22 can also be fixed together with the closure plate 21 by welding or other connection methods. The ear plate 22 extends towards the side of the rotating mechanism 3, and the purpose of this arrangement is to provide a connection point for the rotating mechanism 3, so that the rotating mechanism 3 can drive the side plate 2 to rotate. The ear plate 22 is used to connect with the rotating mechanism 3 and the linear drive mechanism 4, and when the rotating mechanism 3 is activated, it drives the side plate 2 to rotate through the ear plate 22. In addition to being connected with the rotating mechanism 3, the ear plate 22 is also used to rotate and connect with the linear drive mechanism 4, and the purpose of this arrangement is that when the linear drive mechanism 4 is activated, it will drive the side plate 2 to move linearly through the ear plate 22, rather than rotating. Therefore, the design of the side plate 2 allows it to move complexly through the rotating mechanism 3 and the linear drive mechanism 4. The closure plate 21 is responsible for closing the opening of the bucket, and the ear plate 22 provides a connection point for the rotating mechanism 3 and the linear drive mechanism 4, so that the side plate 2 can be easily opened, closed and moved to the bottom of the bucket body 1. This design makes the bucket device more flexible and functional, and can adapt to different working environments and needs.

[0052] That is, the ear plate 22 is provided to connect the linear drive mechanism 4 and assemble the rotating mechanism 3. The linear drive mechanism 4 is connected with the ear plate 22 through the reserved hole of the ear plate 22, to ensure that the displacement of the side plate 2 in the horizontal direction is realized and controlled through the hydraulic system transmission.

[0053] Again referring to Figure 1 and Figure 2In a feasible embodiment of the present application, the rotating mechanism 3 can include a first motor (not shown in the figure), a first gear 31 and a second gear 32. The first motor is used to provide the power of rotation, and is arranged outside the bucket body 1 to facilitate heat dissipation and maintenance, and also does not occupy the space inside the bucket body 1. The first motor is the power source of the rotating mechanism 3, which provides the necessary power to drive the side plate 2 to rotate. The first gear 31 is connected with the output shaft of the first motor and rotates with the operation of the first motor. When the first motor starts, it will drive the first gear 31 to rotate. The first gear 31 plays a role of transmission in the rotating mechanism 3, and transmits the rotating power of the first motor to the second gear 32. The second gear 32 is arranged on the ear plate 22, and is located at a position corresponding to the first gear 31, and is in meshing transmission with the first gear 31. When the first gear 31 rotates, the first gear 31 drives the second gear 32 to rotate in the opposite direction. Under the action of the second gear 32, the side plate 2 can realize 360-degree rotational displacement, and the trajectory of the side plate 2 in the deformation process can be controlled through the forward and reverse rotation of the first motor.

[0054] Of course, the rotating mechanism 3 can also be arranged to rotate as a sprocket, as long as the rotation of the side plate 2 can be realized. Regardless of the specific structure of the rotating mechanism 3, the side plate 2 can rotate according to the predetermined trajectory to switch between the first working state and the second working state.

[0055] After the deformation of the bucket is completed, the side plate 2 is located at the back side of the bucket, and the long strip-shaped load can be placed without any obstruction. And to a certain extent, it has the function of a fork, and can be used for the work of picking up goods. Because of the deformation function of the bucket, it can adapt to more diversified loading requirements in the use scene.

[0056] Among them, the front side of the bucket refers to the side for accommodating goods, and the back side of the bucket refers to the side opposite to the front side of the bucket.

[0057] In a feasible embodiment of the present application, the linear drive mechanism 4 includes a hydraulic cylinder 41 and a piston rod 42. The hydraulic cylinder 41 is used to achieve stable motion transmission, and the transmission efficiency is better than that of a gear structure. In addition, the hydraulic cylinder can achieve self-lubrication in use, so it has the characteristics of long service life. The hydraulic cylinder 41 is arranged on the bucket body 1 to ensure its stability and reliability. The hydraulic cylinder 41 is filled with hydraulic oil, and when it is subjected to external pressure or a control signal, it will generate linear motion through the internal piston. The piston rod 42 is in sliding connection with the hydraulic cylinder 41. The piston rod 42 is installed inside the hydraulic cylinder 41 and forms a sliding connection with it. When the hydraulic cylinder 41 is subjected to pressure, the piston rod 42 will move linearly inside the hydraulic cylinder 41. The piston rod 42 is rotatably connected with the side plate 2. Although the piston rod 42 moves linearly, it means that when the piston rod 42 moves linearly, it can drive the side plate 2 to move linearly. However, the connection between the piston rod 42 and the side plate 2 is rotational. The purpose of this arrangement is that when the side plate 2 rotates with the rotating mechanism 3, the piston rod 42 will not rotate and will not generate a torsional force with the side plate 2. Specifically, the rotational connection between the piston rod 42 and the side plate can use a rotary joint.

[0058] As can be seen, the design of the linear drive mechanism 4 combines the linear motion of the hydraulic cylinder 41 and the rotational connection between the piston rod 42 and the side plate 2, so that the side plate 2 can realize linear motion under the drive of linear motion. This design is simple and efficient, and provides stable linear driving force for the bucket device, so that the side plate 2 can be easily moved to the bottom of the bucket body 1.

[0059] In a feasible embodiment of the present application, the bucket body 1 has openings at both ends, which means that the two ends of the bucket are not completely closed. In order to close the two openings, the side plate 2 is provided with a pair (i.e. two side plates 2). Generally, the two side plates 2 are also symmetrical, one side plate 2 closes one opening, and the other side plate 2 closes the other opening. The rotating mechanism 3 is provided with two, and a pair of side plates 2 are arranged corresponding to the openings at both ends, and the rotating mechanism 3 is connected with the side plate 2 one by one. When the rotating mechanism 3 is activated, it will only drive the side plate 2 connected with it to move, which means that each rotating mechanism 3 is connected with a certain specific side plate 2, rather than driving both side plates 2 at the same time. This design allows the operator or control system to independently control the opening and closing of each side plate, thereby more flexibly and efficiently working. When both side plates 2 are opened, i.e. both side plates 2 are separated from the bucket body in the transverse direction, the transverse obstacle is realized.

[0060] Again referring to Figure 1 and Figure 2As shown, in one possible embodiment of the present application, it further comprises a tightening mechanism 5, which is provided on the bucket body 1, and is used to tighten the cargo with the bucket body 1. The tightening mechanism 5 is an important component in the bucket device, and its main function is to firmly tighten the cargo with the bucket body 1 together, to ensure that the cargo will not fall or shift during transportation or operation. When the bucket body 1 grabs the cargo, the tightening mechanism 5 will contact the cargo, and through some way to exert a tightening force on the cargo, such as chain, rope, belt tensioning, etc., as long as it can tighten the cargo and make it relative fixed with the bucket, to ensure the stability and safety of the cargo in the bucket. The main purpose of the tightening mechanism 5 is to prevent the cargo from falling or shifting from the bucket during transportation or operation. This is very important to ensure the safety of work and improve work efficiency.

[0061] In one possible embodiment of the present application, specifically, the tightening mechanism 5 comprises a tightening belt body 51 and a tightening belt joint 52, the tightening belt body 51 is used to provide guidance for the rope, and the tightening belt body 51 is a specific structure or channel designed on the bucket body 1. Its main function is to provide a clear path or guidance for the rope, to ensure that the rope can correctly act on the cargo. Through the guidance of the tightening belt body 51, the rope can be guided to the desired position, so as to ensure that it can effectively contact the cargo and exert a tightening force. This helps to prevent the confusion or wrong application of the rope, and improves the efficiency and reliability of tightening. The tightening belt joint 52 is used to fix the rope, and the tightening belt joint 52 is a specially designed structure for fixing or connecting the rope. It can be a ring, hook or other type of connecting device, which can be tightly connected or fixed with the end of the rope. Through the tightening belt joint 52, the rope can be firmly fixed on the bucket body 1, so as to ensure that it will not loosen or fall off during work. This helps to maintain the continuity and stability of the tightening force, and ensures the safety and stability of the cargo in the bucket.

[0062] In one possible embodiment of the present application, the tightening mechanism 5 has multiple, and the multiple tightening mechanisms 5 are arranged between a pair of side plates 2. The arrangement of multiple tightening mechanisms 5 can significantly improve the tightening effect and stability of the cargo by the bucket device. They are evenly distributed in different positions of the bucket, and work together to ensure the safety and stability of the cargo in the bucket. This design makes the bucket device more adaptable to different working environments and needs.

[0063] The working principle of the variable bucket provided by the application is as follows: when deformation is performed, the outward thrust is transmitted through the hydraulic cylinder body 41 and the piston rod 42, so that the side plate 2 is separated from the embedded structure of the bucket body 1. Then, the first motor controls the rotation mechanism 3 composed of the first gear 31 and the second gear 32, and the first motor realizes forward rotation and reverse rotation, and the control of the rotation speed and the rotation distance. Thus, the side plate 2 is rotated to an appropriate angle, and collision in the subsequent contraction process is avoided. After the side plate 2 is rotated, the piston rod 42 is contracted to an appropriate position, so that interference of the equipment in the working process is avoided. The deformation process is completed, and the structure state of the loading data is transversely unobstructed. When the bucket is deformed, the piston rod 42 is extended, the side plate 2 is rotated, and then the piston rod 42 is contracted and the inward contraction pressure is maintained. In this way, the side plate 2 can have better stability after being combined with the bucket body 1, so that the structure is not unstable due to collision of the bucket during the loading process of the equipment or displacement of the equipment. Such a deformation structure design can cover more use scenarios in the use process. The equipment can perform normal loading work, and the equipment has the attribute of loading long strip goods through the quick and convenient deformation process.

[0064] The tightening belt body 51 device cooperates with the tightening belt joint 52, and the tightening belt device therein is used to bundle and tighten the goods when the goods are loaded in the bucket fork. The tightening belt joint 52 is fixed to the fixing interface reserved on the tightening belt body 51, and the fixing of the goods is completed. In the unloading process, the tightening degree of the tightening belt body 51 device is released, and the goods can be slowly released, so that the protection of the goods in the unloading process is realized.

[0065] The second aspect embodiment of the application provides a working machine including the variable bucket according to any one of the above embodiments.

[0066] The working machine provided by the second aspect embodiment of the application can avoid unnecessary collision and wear when the variable bucket switches between the first working state and the second working state, and can reinforce the goods during loading, so that the stability of the goods during transportation is ensured.

[0067] In the embodiment of the second aspect of the application, the type of the working machine does not constitute a limitation, for example, the working machine can be an excavator, a loader or the like. In other words, as long as the working machine can use the variable bucket in the application, the working machine can be used.
