[0039] Referring to Figures 1-6 The present application provides a sidewalk grading gravel mixing device, comprising:

[0040] The shell 100 comprises a side plate 110 and a cover plate 120, and a mixing space 130 is formed between the side plate 110 and the cover plate 120. The side plate 110 is inclined at a predetermined angle so that one end of the side plate 110 is close to the ground, and the other end of the side plate 110 is away from the ground. The cover plate 120 is connected with the side plate 110 and also has a ground-close end 121 and a ground-away end 122;

[0041] The driven shaft 200 is installed in the mixing space 130 and is rotationally connected with the ground-close end of the side plate 110. A plurality of mounting flanges 210 are provided on the driven shaft 200, and a mixing part is mounted on the mounting flanges 210;

[0042] The driving part 300 is drivingly connected with the driven shaft 200 through the transmission shaft 700;

[0043] The moving assembly comprises a wheel 410, a connecting rod 420, a connecting ring 430 and a locking part. The connecting ring 430 is fixedly connected with the ground-away end 122 of the cover plate 120. The connecting rod 420 extends into the connecting ring 430 to slide in the connecting ring 430. The wheel 410 is rotationally connected with the ground-close end of the connecting rod 420. The locking part fixes the connecting rod 420 to the connecting ring 430;

[0044] The traction assembly is connected with the ground-away end 122, and is used for connecting a traction machine.

[0045] In the technical scheme adopted in this embodiment, the driving member 300 drives the transmission shaft 700 to rotate, the transmission shaft 700 further transmits power to the driven shaft 200, the driven shaft 200 drives the turning and stirring part to rotate, and the turning and stirring part turns and stirs the graded gravel after paving. Since the graded gravel may be thrown out following the turning and stirring part during the turning and stirring process, the side plate 110 and the cover plate 120 are arranged to block the graded gravel thrown up, so that the graded gravel is always in the turning and stirring space 130 and is prevented from being thrown up to hurt people or be scattered everywhere. The side plate 110 and the cover plate 120 are both arranged in an inclined manner, so that the whole shell 100 is also in an inclined state, one end of the shell 100 is close to the ground, and the other end of the shell 100 is far from the ground. The driven shaft 200 is arranged at the end close to the ground, and other components are arranged at the end far from the ground. In this way, the turning and stirring part can conveniently turn and stir the graded gravel after paving, and the graded gravel thrown up can be prevented from impacting other components to damage the functions of the other components. Through cooperation of the traction assembly and the moving assembly, the device can be connected with a traction machine to drive the turning and stirring device to move on the roadbed of the sidewalk, or the paving equipment of the graded gravel can be selected as the traction device to enable the paving construction and the turning and stirring construction to be performed synchronously. In addition, the connecting rod 420 in the moving assembly can be fixed at different positions of the connecting ring 430. By adjusting the position of the connecting rod 420 relative to the connecting ring 430, the inclination angle of the whole turning and stirring device relative to the ground can be adjusted. The inclination angle of the whole device relative to the ground can affect the turning and stirring depth of the turning and stirring part. Through connection with the traction equipment, the device can move on the roadbed to turn and stir the graded gravel after paving.

[0046] Specifically, the connecting ring 430 and the connecting rod 420 are both provided with locking holes 450, and the locking member is a locking pin 440. The locking pin 440 extends into the locking hole 450 to fix the connecting rod 420 to the connecting ring 430. A plurality of locking holes 450 are arranged on the connecting rod 420 to realize locking of different positions of the connecting rod 420. The moving assembly is provided with two groups, which are arranged on both sides in the width direction of the cover plate 120. In addition, since the turning and stirring device mainly moves on the surface of the graded gravel, the surface has many sharp protrusions and is uneven, and therefore the wear resistance of the wheel 410 is required to be high. If the wear degrees of the wheels 410 on both sides are different, the whole device will be high on one side and low on the other side in the width direction, which will affect the turning and stirring effect of the turning and stirring part on the graded gravel. Therefore, the wheel 410 is provided with a rubber layer, the rubber layer is fluorine rubber, the rubber layer is in contact with the ground, and the fluorine rubber has high wear resistance and can meet the requirements of moving on the graded gravel and is not easy to be worn by the graded gravel.

[0047] The driving member 300 can be any device capable of finally driving the driven shaft 200 to rotate, such as a motor, an engine or the like. The driving member 300 and the transmission shaft 700 are both arranged on the side of the cover plate 120 away from the turning and stirring space 130, and the driving member 300 is mounted to the cover plate 120.

[0048] Further, the turning and stirring part comprises turning plates 600, the turning plates 600 are bent at a predetermined angle, both sides of the mounting flange 210 are provided with the turning plates 600, and the bending directions of the turning plates 600 on both sides of the mounting flange 210 are opposite, and the plurality of turning plates 600 form the turning and stirring part.

[0049] Specifically, in the embodiment, four turning plates 600 are mounted on each mounting flange 210, two on each side, and the four turning plates 600 form a cross structure. The turning plates 600 mounted on the left side of the mounting flange 210 are bent to the left, and the turning plates 600 mounted on the right side of the mounting flange 210 are bent to the right. In addition, more turning plates 600 can also be provided on the mounting flange 210 to form a star structure or other structures. Since the graded gravel has a certain hardness, the turning plates 600 are prevented from being deformed or broken due to collision with the gravel during the turning and stirring process. The material of the turning plates 600 is 18-8 stainless steel, which has good toughness and can meet the turning and stirring function and is not easy to deform or break. The turning plates 600 and the flanges are connected by bolts or screws.

[0050] Further, the traction assembly comprises:

[0051] A traction plate 510, the traction plate 510 is fixedly connected with the remote end 122, and the traction plate 510 is provided with a locking hole;

[0052] A pin shaft 520, the pin shaft 520 connects the traction plate 510 and the traction mechanism through the locking hole.

[0053] The traction assembly is connected with the corresponding traction part on other machines, so that the device can move on the graded gravel under the traction of other machines. The connection between the turning and stirring device and other machines is achieved by pin shaft 520 insertion, and the connection mode has high connection stability.

[0054] In addition, in order to prevent the traction plate 510 from being incompatible with some machines, the turning and stirring device is also provided with a traction frame 530, which is arranged at the center of the cover plate 120 in the width direction.

[0055] Further, the transmission shaft 700 is a five-step stepped shaft, and the transmission shaft 700 is rotatably connected with the side plate 110 through a bearing; and / or,

[0056] The driven shaft 200 is rotatably connected with the side plate 110 through a bearing.

[0057] When the graded gravel is turned over, the driven shaft 200 needs to provide a large torque for the turning plate 600 to ensure the turning effect, so the transmission shaft 700 needs to be able to withstand a large torque. Compared with ordinary shafts, stepped shafts have higher torsional stiffness, which are composed of shafts of different sizes, the diameters of which gradually increase to form a series of stepped shapes, and the shafts of different diameters have different bending degrees when subjected to external force, together bearing the load of the torque, and the stepped shaft can withstand and transmit higher torque. Specifically, the smallest diameter shaft segment of the stepped shaft is connected with the driving part 300, and the largest diameter shaft segment of the stepped shaft is connected with the side plate 110 through a bearing. Similarly, the driven shaft 200 is also rotatably connected with the side plate 110 through a bearing.

[0058] The part of the transmission shaft 700 and the driven shaft 200 passing through the side plate 110 is provided with a gear, the outside of which is sleeved with a chain, and the transmission shaft 700 and the driven shaft 200 are driven through the chain. Compared with a belt or other transmission structure, the chain transmission can transmit a larger torque and will not slip. In addition, the working environment of the turning device is poor, full of clay, sand, gravel and other impurities, which may affect the transmission. Compared with other transmission structures, the chain transmission is more suitable for working in a poor environment.

[0059] Specifically, the chain is arranged on the side of the side plate 110 away from the turning space 130, in order to prevent external clay, sand, gravel and other impurities from affecting the power transmission between the transmission shaft 700 and the driven shaft 200, a protective shell 800 is arranged to cover and protect the connection between the chain, the driven shaft 200 and the side plate 110, and the connection between the transmission shaft 700 and the side plate 110.

[0060] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application, any equivalent structural transformation made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
